Description

  The present invention relates to a wall surface construction method for constructing a wall surface by stacking a plurality of panel bodies and filling the back surface of each stage of the panel body with a back-in part.

  Conventionally, as this type of wall surface construction method, for example, a plurality of concrete molds disclosed in Patent Document 1 are stacked, and concrete is placed on the back of the concrete molds, while the walls of a sabo dam or concrete are placed. There are things that build retaining walls. A concrete formwork is a square concrete panel. When this panel is stacked and a wall surface is constructed, as shown in FIG. 1 of the same document, a bolt hole drilled in a connecting bracket attached to the lower panel is provided on the back surface of the upper panel. Fits into embedded bolt hole. Then, the bolts are inserted into the bolt holes drilled in the connecting bracket and screwed into the embedded bolt holes provided on the back surface of the upper panel so that the upper and lower panels are connected via the connecting bracket. Connected. As shown in FIG. 2 of the same document, when four connecting brackets having a wide panel side are provided on the back of the panel, bolt holes and upper connecting brackets formed in the lower panel connecting brackets are provided. The upper and lower panels are connected to each other by fitting the bolt holes drilled in the holes and inserting screws into the respective bolt holes to fix the connection fittings. In addition, as shown in FIG. 7 of the same document, when the connection holes are provided in the upper and lower edges of the panel, the connection holes provided in the lower panel and the connection holes provided in the upper panel are combined. The upper and lower panels are connected by inserting bolts into the connection holes.

Japanese Patent No. 3242160

  However, in the wall surface construction method disclosed in Patent Document 1 above, when building the wall surface by stacking the panels, the upper panel is compared to the lower panel so that the bolt holes and the connection holes fit each other. Must be located. Therefore, if the positional relationship between the upper and lower panels is shifted when stacking the panels, the bolt holes and the connecting holes are not aligned with each other, so that the upper and lower panels cannot be connected and the wall cannot be constructed. In addition, it is necessary to insert bolts and screws into each bolt hole and each connecting hole to fasten the upper and lower panels, and to provide temporary support materials to support the panels in order to make the panels stand alone. In some cases, it took a lot of work and the panel stacking work efficiency was not good.

  In addition, when stacking the upper panel on the lower panel, it is difficult to install the upper panel directly above the lower panel so that the walls of each panel are flush with each other. When the upper panel body is shifted to the side or the rear side, an operation for correcting this shift occurs, and the panel stacking work efficiency decreases.

  Also, when used on the wall of a flexible structure such as a reinforced earth method, the upper and lower panels are rigidly connected with bolts and screws, so the embankment behind the panel is deformed and the back of the panel If the load is applied unevenly, a large load may be locally applied to the bolt or screw that rigidly connects the panels, and these may be damaged, and the wall is constructed by the conventional wall construction method disclosed in Patent Document 1 above. The wall surface was inferior in durability. In addition, when the embankment behind the panel sinks or deforms, the panel that is rigidly connected with bolts and screws cannot move following it, and a cavity is formed on the back side of the panel, etc. As a result, the wall surface is weakened.

  Further, in the case of curved construction in which the laying extension direction of the wall surface is bent, when building a slanted wall surface by stacking panels obliquely, the radii drawn by the panel at the lower part of the wall surface and the panel at the upper part of the wall surface are different. Therefore, a gap that extends from the upper part of the wall surface toward the lower part is generated between the panels. For this reason, when performing curved construction with the wall surface slanted, it is necessary to cast in-fill concrete to fill the gaps between the panels, or to process the trapezoids with different sizes for each stage where the panels are stacked Conventionally, much work has been required for the construction of the interstitial concrete and the panel processing.

The present invention has been made to solve such problems,
The end protrudes upward from the front and back sides of the lower panel body, and is provided on the lower panel body with a predetermined gap between at least one of the front or back of the upper panel body and the end. Alternatively, the upper panel body is positioned between the front connection member and the rear connection member to be provided, or the ends protrude downward from the front side and the rear side of the upper panel body, The upper panel body so that the lower panel body is sandwiched between the front connection member and the rear connection member provided or provided on the upper panel body with a predetermined gap between at least one of the rear surface and the end portion. A first support step and a support jig interposed between the front or back and the end of the upper or lower panel body having a predetermined interval. Stacked panel body as one cycle and the second step of fixing a,
A wall surface construction method for constructing a wall surface by performing the third step of filling the back surface of the panel main body to a predetermined height with the back portion after any cycle was configured.

  According to this configuration, in the first step, the end portion protrudes upward from the front side and the back side of the lower panel body, and is provided between or provided on the lower panel body. The upper panel body is positioned on the upper panel body, or the end portion protrudes downward from the front side and the rear side of the upper panel body, and the front connection member and the rear connection member provided or provided on the upper panel body. The upper panel body is positioned so that the lower panel body is sandwiched therebetween, and a predetermined distance between the front or rear surface of the upper or lower panel body and the end of the front coupling member or the rear coupling member is determined by the second step. A support jig is interposed while there is a gap, and the panel body is fixed and stacked. It is possible to match supported by the position.

  For this reason, when stacking the panel main bodies, it is possible to pack the panel main bodies from the end for each stage without considering the positional relationship between the upper and lower panel main bodies in the laying extension direction. Therefore, when the panels are stacked, the positional relationship between the upper and lower panels is shifted, so that the bolt holes and connection holes of the upper and lower panels do not match each other as before, and the upper and lower panels cannot be connected with bolts or screws. Thus, the wall cannot be constructed.

  In addition, when stacking multiple panel bodies, the upper and lower panel bodies are simply engaged with each other by the front connection member and the rear connection member, and between the panel body and the end of the front connection member or the rear connection member with a predetermined gap. By interposing a support jig on the upper and lower panel bodies, the upper and lower panel bodies support each other, and the panel body becomes independent. For this reason, the work of fastening the upper and lower panels with bolts and screws and the work of providing temporary support materials to support the panels, which have been conventionally performed to make the panels self-supporting, are not required. improves. Moreover, since the shape of the panel body can be made thin and simple, the manufacturing cost of the wall surface can be greatly reduced.

  In addition, when the upper panel body is stacked on the lower panel body, when the front connection member and the rear connection member are pre-attached or integrally molded to the lower or upper panel body, the upper panel body is It is guided and moved by a front connecting member and a rear connecting member provided in advance in the lower or upper panel body. Therefore, in this case, it is difficult for the upper panel body to be shifted to the front side or the rear side of the wall surface of the lower panel body, and it can be easily installed directly above the lower panel body. Will improve. The configuration in which the front panel connecting member and the rear panel connecting member engage with the adjacent panel main body is more independent than the configuration in which the front panel connecting member or the rear surface connecting member only engages with the adjacent panel main body. It becomes easy to do. As a result, there is provided a wall surface construction method capable of constructing a wall surface with a simple work process, good work efficiency, and a stable and independent panel body.

  In addition, since it is configured such that a predetermined gap is provided between at least one of the front or back surface of the panel body and the end of the front connection member or the back connection member provided in the adjacent panel body, the lower or upper stage When the front surface connecting member and the back surface connecting member are provided in advance in the panel main body, a gap is secured when the panel main body is positioned in the space between the front surface connecting member and the back surface connecting member. For this reason, the panel main body smoothly moves in the space between the front connection member and the rear connection member, and the pattern provided on the surface of the panel main body is not damaged by being caught on the surface of the panel main body. The work efficiency of stacking work is improved.

  In addition, when used on the wall of a flexible structure such as a reinforced earth method, because the upper and lower panel bodies are not rigidly connected with bolts, etc., if the embankment etc. behind the panel body sinks or deforms, The panel body can move following its subsidence and deformation. Therefore, as in the conventional wall construction method in which panel bodies are rigidly connected with bolts etc., the embankment behind the panel sinks or deforms and the load is applied to the back of the panel, causing the panels to be rigidly connected. A flexible and highly durable wall is built-in, which prevents damage to the bolts, etc. that are applied by a large load locally, and damages the wall due to the formation of a cavity on the back side of the panel. A wall surface construction method is provided.

The present invention also provides:
In the first step, the upper panel between the front connecting member and the rear connecting member provided or provided on the lower panel main body with a predetermined interval between the front and back surfaces and the end of the upper panel main body. Position the main body, or provide a predetermined gap between the front and back surfaces of the lower panel main body and the end, and the lower panel between the front connecting member and the rear connecting member provided or provided on the upper panel main body. Position the upper panel body so that the panel body is
In the second step, at least one support jig is interposed between one end of the front connection member and the back connection member and the front or back surface of the panel body, and the other end of the front connection member and the back connection member. The panel main body is fixed by interposing at least two support jigs at positions higher and lower than any one of the support jigs between the rear surface and the front surface of the panel main body.

  According to this configuration, in the second step, at least one support jig is interposed between one end of the front connection member and the back connection member and the front surface or the back surface of the panel body, and the front connection member and the back surface The at least two support jigs are interposed between the other end of the connecting member and the back surface or the front surface of the panel main body at a position higher and lower than any one of the support jigs, so that the first step In the lower panel body, the lower panel body is positioned between the front connection member and the rear connection member provided or provided or provided between the front connection member and the rear connection member. The upper panel body positioned so as to be sandwiched is fixed.

  For this reason, for example, one support jig is interposed between the end of the front connection member provided on the lower panel body and the front surface of the upper panel body, and the rear surface provided on the lower panel body. When two support jigs are interposed between the end of the connecting member and the back surface of the upper panel main body at a position higher and lower than the one support jig, the panel main body is tilted forward and stacked. Even if the load that causes the upper panel body to fall to the front side is applied to the upper panel body from the rear side due to the weight of the panel body or due to the side pressure from the back part provided on the back surface of the panel body, etc. One support jig interposed between the end of the front connection member and the front surface of the upper panel body, and one support jig between the end of the back connection member and the rear surface of the upper panel body In the lower position The supporting jig, the load is received. In addition, the load that causes the upper panel body to fall to the back side due to the weight of the panel body due to the panel body being tilted backward and due to some side pressure applied to the front surface of the panel body is applied to the upper panel body. One support jig interposed between the end portion of the front connection member and the front surface of the upper panel body, and between the end portion of the rear connection member and the rear surface of the upper panel body, even from the front side. This load is received by the support jig interposed at a position higher than one support jig. As a result, since the load applied from both the front side and the back side can be received by the support jig, there is a predetermined gap between the front and back sides of the panel body and the ends of the front connecting member and the back connecting member. However, the panel body can be securely fixed without the panel body falling over or wobbling.

  Also, when the panel body is stacked without aligning the positional relationship between the upper and lower panel bodies in a curved construction where the laying extension direction of the wall surface is bent, the panel body stacked below and the panel body stacked above are not one side, Intrusion occurs between the front side or the back side of the panel body. Further, when the panel main bodies are stacked with the upper and lower panel main bodies aligned, the panel main body stacked below and the panel main body stacked upward do not have such entry / exit. However, according to this configuration, a gap is provided between the front and back surfaces of the panel main body and the end portions of the front connecting member and the rear connecting member, whether or not they come in and out. By interposing the support jig, the panel main body can be fixed without the front and back surfaces of the panel main body and the front connecting member and the end of the back connecting member colliding with each other. Similarly, a panel main body having an uneven pattern on the surface can also be fixed. Therefore, by adjusting the mounting position of the support jig according to the direction of the load applied to the panel body, and by adjusting the number of support jigs to be interposed according to the magnitude of the load applied to the panel body, It is possible to construct a strong wall that can be freely adapted to various situations such as the direction and size of the load applied to the panel body.

  In addition, whether or not it comes in and out, by providing a gap between the front and back of the panel body and the front connection member and the end of the back connection member, interposing a support jig in this gap The upper and lower panel bodies can be supported at desired positions in the wall extending direction without colliding with the front and back surfaces of the panel body and the front connection members and the end portions of the back connection members. When performing curved construction, without considering the positional relationship of the upper and lower panel bodies in the laying extension direction, the panel body is packed from the end for each step, and the panel body is tilted diagonally without aligning the upper and lower panel body positions. Can be stacked. Therefore, only a slight gap corresponding to the difference in curvature radius corresponding to the height of the panel body itself is generated between the panel bodies in the laying extension direction. For this reason, it is no longer necessary to place interstitial concrete that fills the gaps that occur between the panel bodies or to form trapezoids with different sizes for each stage in which the panels are stacked. As a result, the work efficiency of panel stacking work is greatly improved.

The present invention also provides:
In the first step, the upper panel between the front connecting member and the rear connecting member provided or provided on the lower panel main body with a predetermined interval between the front and back surfaces and the end of the upper panel main body. Position the main body, or provide a predetermined gap between the front and back surfaces of the lower panel main body and the end, and the lower panel between the front connecting member and the rear connecting member provided or provided on the upper panel main body. Position the upper panel body so that the panel body is
In the second step, at least one support jig is interposed between one end of the front connection member and the back connection member and the front or back surface of the panel body, and the other end of the front connection member and the back connection member. The panel body is fixed by interposing at least one support jig at a height different from any one of the support jigs between the back surface and the front surface of the panel body.

  According to this configuration, in the second step, at least one supporting jig is interposed between one end of the front connection member and the back connection member and the front surface or the back surface of the panel body, so that the front connection member and the back connection are provided. By interposing at least one support jig at a height different from any one of the support jigs between the other end of the member and the back surface or the front surface of the panel body, in the first step, The lower panel body is sandwiched between the front connection member and the rear connection member provided or provided between the front connection member and the rear connection member provided or provided on the panel main body. The positioned upper panel body is fixed.

  For this reason, for example, one support jig is interposed between the end of the front connection member provided on the lower panel body and the front surface of the upper panel body, and the rear surface provided on the lower panel body. When a support jig is interposed between the end of the connecting member and the back surface of the upper panel body, the panel body is tilted backward and stacked when the support jig is interposed at a position higher than one support jig on the front side. Even if the upper panel body is loaded on the upper panel body from the front side due to the weight of the main body or due to some lateral pressure applied to the front surface of the panel body, the load is applied to the lower panel body. One supporting jig interposed between the end of the front connecting member and the front of the upper panel body, and the end of the back connecting member provided on the lower panel main body and the back of the upper panel main body of In, the support jig interposed higher than one support fixture of the front-side position, the load is received. Further, between the end of the front connection member provided on the lower panel body and the front surface of the upper panel body, and between the end of the back connection member provided on the lower panel body and the upper panel body. A support jig is interposed between the back surface and the panel body as described above. When the panel body is stacked and the wall surface is constructed diagonally, the panel body is inclined by moving the panel body to the back side. It is possible to counter a lateral pressure from a back-side portion or the like on the back side of the panel main body according to the inclination angle. As a result, the load from the front side can be received by the support jig, and the load from the back side can be received by the weight of the panel body. Further, when the panel body is stacked and the wall surface is constructed vertically, it is possible to counter the lateral pressure from the front and back surfaces of the panel body according to the weight of the vertically standing panel body. For this reason, even if there is a predetermined gap between the front and back of the panel main body and the end of the front coupling member and the rear coupling member, the panel main body is securely fixed without falling or wobbling. can do.

  In addition, when the panel body is stacked diagonally without aligning the positional relationship between the upper and lower panel bodies in curved construction, the panel body stacked below and the panel body stacked above are not one side, the upper and lower panel bodies Entry / exit occurs between the front side or the back side of the. Further, when the panel main bodies are stacked with the upper and lower panel main bodies aligned, the panel main body stacked below and the panel main body stacked upward do not have such entry / exit. However, according to this configuration, the panel body is inclined to the back side, whether or not it comes in and out, and between the front and back surfaces of the panel body and the ends of the front connection member and the back connection member. By providing a gap and interposing these support jigs in the gap, the panel body can be fixed without the front and back surfaces of the panel body and the front connection members and the end portions of the back connection members colliding with each other. Similarly, a panel main body having an uneven pattern on the surface can also be fixed.

  Also in this configuration, a gap is provided between the front and rear surfaces of the panel main body and the end portions of the front coupling member and the rear coupling member, and a support jig is interposed in the gap, so that the front and rear surfaces of the panel main body are provided. The upper and lower panel bodies can be supported at a desired position in the wall extending direction without colliding with the ends of the front connection member and the rear connection member. Without considering the positional relationship of the panel body in the laying extension direction, it is possible to pack the panel body diagonally without aligning the positional relationship of the upper and lower panel bodies by packing the panel body from the end for each stage. Therefore, only a slight gap corresponding to the difference in curvature radius corresponding to the height of the panel body itself is generated between the panel bodies in the laying extension direction. For this reason, even with this configuration, it is necessary to place interstitial concrete that fills the gaps generated between the panel bodies, or to process a trapezoid with a different size for each stage on which the panels are stacked, as in the past. As a result, the construction work of the interstitial concrete and the panel processing work are reduced, and the work efficiency of the panel body stacking work is greatly improved.

  In addition, the present invention is characterized by performing a fourth step of removing the front connecting members that engage the panel bodies whose back surfaces are filled up to a predetermined height by the back portion in the third step.

  According to this configuration, the front connection members that engage the panel bodies whose back surfaces are buried to a predetermined height by the back portion are mutually removed in the fourth step, and the removed front connection members are connected to the other panel bodies. As a result, the number of connecting members required for the construction of the wall surface is reduced, and the manufacturing cost of the wall surface is reduced.

  Further, in the second step, in the second step, one end of the support jig is screwed to the end portion of the front connection member or the rear connection member having a predetermined interval, and the support jig is rotated to be taken in and out. The protruding end of the jig is brought into contact with and engaged with the front or back of the upper or lower panel body, and the panel body is fixed.

  According to this configuration, the support jig is rotated so that the protruding end of the support jig whose one end is screwed into the end of the front connection member or the back connection member is taken in and out, and the front or back surface of the upper or lower panel body By being brought into contact with and engaged with each other, a support jig is interposed between the front surface or the back surface and the end portion of the upper or lower panel body having a predetermined interval, and the panel body is fixed. For this reason, the upper and lower panel bodies can be easily supported together by adjusting the insertion / removal of the supporting jig to / from the front or rear side of the panel body of the front coupling member or the rear coupling member engaged with the adjacent panel body. It is possible to engage without wobbling, and work efficiency is improved.

  Further, in the present invention, in the second step, the panel body is fixed by inserting or sandwiching a support jig between the front or back surface and the end of the upper or lower panel body having a predetermined interval. It is characterized by.

  According to this configuration, the upper or lower panel body having a predetermined interval is inserted by inserting or sandwiching the support jig between the front or back surface and the end of the upper or lower panel body having a predetermined interval. A panel is fixed by interposing a support jig between the front surface or the back surface and the end portion of the panel. For this reason, by adjusting the amount by which the support jig is inserted between the front or back surface of the adjacent panel body and the end of the front connection member or the back connection member, or by adjusting the thickness of the support jig to be sandwiched Thus, the upper and lower panel bodies can be easily supported and engaged without wobbling, and the working efficiency is improved.

  Further, the present invention is such that a support jig projects from the end of the front connection member or the back connection member with a predetermined interval, and the upper panel body is positioned on the lower panel body in the first step. The panel body is fixed by interposing a support jig between the front or back of the upper or lower panel body having a predetermined interval and the end, and the first step and the second step are performed simultaneously. Features.

  According to this configuration, the upper panel body is positioned between the front connection member and the rear connection member provided or provided on the lower panel body, or the front connection provided or provided on the upper panel body. The first step of positioning the upper panel main body so that the lower panel main body is sandwiched between the member and the rear connecting member, so that a support jig is attached to the end of the front connecting member or the rear connecting member having a predetermined interval. And the second step of fixing the panel body is performed simultaneously. For this reason, the stacking work efficiency of the panel main body is improved because the second step does not need to be performed as a separate step.

  Moreover, this invention is an 1st process. By inserting an adjustment material between the attachment surface to the panel main body of a front surface connection member or a back surface connection member, and the front surface or back surface of a panel main body, an adjacent panel main body is inserted. A predetermined interval is provided between the front surface or the back surface and the end portion.

  According to this configuration, the adjustment material is interposed between the front connecting surface of the front connecting member or the rear connecting member to the panel main body and the front surface or the rear surface of the panel main body, so that the end of the front connecting member or the rear connecting member. And a predetermined interval between the adjacent panel main bodies is adjusted according to the size of the in / out between the upper and lower panel main bodies and the protruding state of the pattern. By this adjustment, it is possible to avoid collision between the end portion of the front connection member or the back connection member and the adjacent panel body.

  In the first step, the thickness of the panel body of the portion where the front connection member or the back connection member is fixed to the panel body is adjacent to a portion where the thickness of the front connection member or the back connection member faces the end of the front connection member. The thickness of the panel body is larger than the thickness of the panel body so that there is a predetermined interval between the adjacent panel body and the end portion.

  According to this configuration, the thickness of the panel main body of the portion where the front connecting member or the rear connecting member is fixed to the panel main body is equal to the thickness of the panel main body adjacent to the portion facing the end of the front connecting member or the rear connecting member. By being thicker than this, a predetermined interval is provided between the adjacent panel body and the end. For this reason, it is possible to avoid collision between the adjacent panel main body and the end of the front connection member or the rear connection member due to the entry / exit between the upper and lower panel main bodies and the unevenness of the pattern.

  In the first step, the front connection member or the back connection member may be bent so that the adjacent panel body that is provided or engaged with the provided panel body forms a surface having a predetermined shape. It is characterized by being.

  According to this configuration, the panel body provided with or provided with the front connection member or the back connection member and the adjacent panel body engaged with the front connection member or the back connection member form a surface having a predetermined shape. The front connecting member or the rear connecting member is bent. For this reason, a wall surface having a desired shape is constructed by stacking the panel body using a front connection member or a rear connection member bent so as to form a surface having a desired shape in an adjacent panel body. Can do. For example, when the panel body is stacked on the front surface of the existing structure, using the front connection member or the back connection member that is bent so as to form a surface having the same shape as the wall surface shape of the existing structure with the adjacent panel body, By stacking the panel body, it is possible to construct a new wall surface that matches the wall surface shape of the existing structure.

  Further, the present invention is characterized in that, in the first step, the panel body is bent so as to form a surface having a predetermined shape with an adjacent panel body engaged through the front connection member and the back connection member. And

  According to this structure, the panel main body is bent so as to form a surface having a predetermined shape with the adjacent panel main body engaged through the front connecting member and the rear connecting member. For this reason, a wall surface having a desired shape can be constructed by stacking panel bodies bent so as to form a desired surface. For example, when the panel body is stacked on the front surface of the existing structure, the panel body is stacked using the panel body bent in the same shape as the wall surface shape of the existing structure, so that it matches the wall shape of the existing structure. New wall surfaces can be constructed.

  In the first step, the front panel connecting member or the rear panel connecting member provided or provided in the panel main body is connected to the panel at one end farther away from the fixed portion with the panel main body. A fulcrum that contacts the front surface or the back surface of the main body is provided.

  According to this configuration, even if a load is applied to the end portion side of the front connecting member via the panel main body due to the side pressure of the back portion filled in the back surface of the panel main body, the fulcrum provided at one end of the front connecting member By contacting the front surface of the panel main body on the opposite side of the fixed portion, this load can be received even at a fulcrum that contacts the front surface of the panel main body. In addition, even if a load is applied to the end of the back connecting member through the panel main body due to some lateral pressure applied to the front surface of the panel main body, the fulcrum provided at one end of the back connecting member sandwiches the fixed portion. By contacting the back surface of the panel body, the load can be received at a fulcrum that contacts the back surface of the panel body. For this reason, the load applied to the end side of the front connection member or the back connection member is supported by the fixed position of the front connection member or the back connection member and the fulcrum provided at one end thereof, and the front connection is performed only at the fixed position. Compared to the case where the member or the back surface connecting member is fixed, the front surface connecting member or the back surface connecting member is securely fixed to the panel body without wobbling.

  In the first step, the present invention is characterized in that the front connecting member or the rear connecting member is formed separately from the panel body and is detachably or pivotably attached to the panel body.

  According to this configuration, since the front connecting member or the rear connecting member is formed separately from the panel main body, the front connecting member or the rear connecting member and the panel main body can be separately manufactured at low cost. Or the manufacturing cost of a wall surface can be reduced significantly compared with the case where a back connection member and a panel main body are manufactured integrally. In addition, when stacking the panel body, without considering the positional relationship of the upper and lower panel bodies in the laying extension direction, if the panel body is packed and stacked from the end for each step, each front connection provided on the upper and lower panel bodies The members or the back connecting members and these members and the members provided on the panel body collide with each other. However, when the front connecting member or the rear connecting member is detachably attached to the panel body, the front connecting member or the rear connecting member can be removed by attaching one of the front connecting member or the rear connecting member that is collided to the panel main body or shifted to another position. Collisions between the back connecting members and the members provided on the panel body can be avoided. Further, in the case where the front connecting member or the rear connecting member is rotatably attached to the panel main body, one end of the front connecting member or the rear connecting member that collides with the panel main body around the attachment position of the panel main body. By rotating on the front surface or the back surface, it is possible to avoid a collision between the front connection members or the back connection members or the members provided on the panel body.

  According to the present invention, as described above, when the panels are stacked, the positional relationship between the upper and lower panels is shifted, so that the bolt holes and connection holes of the upper and lower panels do not match each other, and the upper and lower panels are not aligned. Panels cannot be connected with bolts or screws, and walls cannot be constructed. In addition, the conventional work of fastening the upper and lower panels with bolts and screws and the work of providing temporary support materials to support the panels are not required, so the panel body stacking work efficiency is improved. To do. Moreover, since the shape of the panel body can be made thin and simple, the manufacturing cost of the wall surface can be greatly reduced. In addition, when the lower or upper panel body is provided with a front connecting member and a rear connecting member in advance, the upper panel body is difficult to be shifted to the front side or the back side of the wall surface of the lower panel body, It can be easily installed directly above the lower panel body, improving the efficiency of stacking panels. In addition, a wall surface construction method is provided in which the work process is simple, the work efficiency is good, and the wall surface on which the panel body is stable and independent can be constructed. In addition, when the lower or upper panel body is provided with the front connection member and the rear connection member in advance, the panel body moves smoothly between the front connection member and the rear connection member, and the surface of the panel body As a result, the operation efficiency of stacking the panel main body is improved without being damaged by the pattern provided in the uneven shape.

  FIG. 2A is a side view of the wall surface structure in the process of building the panels 1A and 1B shown in FIG. 1 by stacking a plurality of stages by the wall surface construction method of the present embodiment. In the figure, the same parts as those in FIG.

  This wall surface is constructed by stacking a plurality of panel main bodies 1a in a straight line construction in which the laying extension direction is straight or in a potato stacking method (to be described later) in which a wall surface in a curved construction in which the laying extension direction is bent is flush.

  When constructing the wall surface, first, the panel body 1a of the lowermost panel 1A is installed on the foundation 11 on the crushed stone 16 in the preparation. At this time, a triangular pillar-shaped sleeper 12 is installed at the rear end of the holding block 6a provided extending from the position higher than the lower end of the panel main body 1a to the back side, and the inclination angle of the panel 1A is based on the inclination angle. 11 is adjusted perpendicular to the surface. Further, a scissor line 13 is installed at the lower front end of the panel main body 1a via a wedge 14, so that the lowermost panel main body 1a protrudes forward and is prevented from falling over. Note that the spare block 6a may be provided not on the lowermost panel body 1a but on the panel body 1a of the panel 1B stacked in the second and subsequent stages.

  Next, the concrete 15 is placed on the back surface of the panel main body 1a of the lowermost panel 1A installed to a height A that is about half of the panel main body 1a. Thereby, the panel body 1a of the lowermost panel 1A is fixed on the foundation 11 together with the holding block 6a. This completes the preparation.

  Next, in the first step, the panel body 1a of the second panel 1B is stacked on the panel body 1a of the lowermost panel 1A installed. At this time, a predetermined gap is provided between the back surface of the panel body 1a of the upper panel 1B and the engagement surface 3a1 of the back surface connecting member 3a whose other end protrudes upward from the back surface side of the panel body 1a of the lower panel 1A. The panel main body 1a of the upper panel 1B is inserted between the front connection member 2a and the rear connection member 3a, one end of which is attached to the panel main body 1a of the lower panel 1A. Here, the adjustment material 8a is interposed between the attachment surface of the back surface connecting member 3a attached to the panel body 1a of the lowermost panel 1A and the back surface of the panel body 1a of the lowermost panel 1A. A predetermined interval 17 is provided between the back surface of the panel body 1a of the adjacent second-stage panel 1B and the engagement surface 3a1 formed at the end of the back surface connecting member 3a.

  Next, in the second step, one end of the bolt 4c is screwed to the other end of the back surface connecting member 3a having a predetermined interval 17, and the bolt 4c is rotated to move in and out of the engaging surface 3a1 of the back surface connecting member 3a. By doing so, the protruding end of the bolt 4c is brought into contact with and engaged with the back surface of the panel body 1a of the upper panel 1B, and the panel body 1a of the upper panel 1B is fixed. The bolt 4c constitutes a support jig interposed between the back surface of the panel body 1a of the upper panel 1B having a predetermined interval 17 and the engagement surface 3a1 of the back surface connecting member 3a.

  Next, in the third step, the concrete 15 is placed on the back surface of each panel body 1a of the panels 1A and 1B stacked in two steps up to a height B that is about half of the panel body 1a of the second panel 1B. Is done. At this time, the long anchor bolts 4b protruding from the back of each panel body 1a are buried by the concrete 15 and become an anchor for further improving the integration of each panel body 1a and the concrete 15 after curing.

  Next, in the fourth step, after the concrete 15 is cured, the panel of the lowermost panel 1A that engages the panel bodies 1a that are buried to a predetermined height by the concrete 15 whose back surface is cured in the third step. The front connecting member 2a provided on the front surface of the main body 1a is removed. Thereafter, the third panel 1B is similarly stacked on the second panel 1B using the front connecting member 2a and the back connecting member 3a, and the concrete 15 is similarly placed up to the height C behind it. Thereafter, the cycle of the first to fourth steps is repeated to construct the wall surface.

  In the first step described above, before the upper panel main body 1a is stacked above the lower panel main body 1a, the front connecting member 2a and the rear connecting member 3a are tightened with bolts 4a and nuts 5b in advance. When the upper panel main body 1a is stacked above the lower panel main body 1a, the front panel connecting member 2a and the rear connecting member 3a are mounted with their ends protruding above the lower panel main body 1a. The upper panel main body 1a was inserted and positioned in the space. However, the front connecting member 2a and the back connecting member 3a may be provided integrally with the panel main body 1a when the panel main body 1a is formed, instead of being attached to the panel main body 1a with bolts 4a and nuts 5b. . Also, before the upper panel body 1a is stacked above the lower panel body 1a, the bolts 4a and the nuts 5b are loosened, and the ends of the front connection member 2a and the rear connection member 3a are connected to the lower panel body 1a. Leave the front connection member 2a and the back connection member 3a not attached to the lower panel body 1a at all so as not to protrude from above, and stack the upper panel body 1a above the lower panel body 1a. At the same time or after stacking, the ends of the front connection member 2a and the back connection member 3a protrude from above the lower panel body 1a, and the front connection member 2a and the back connection member 3a are tightened with bolts 4a and nuts 5b. Is attached to the panel body 1a, and the upper panel body 1a is positioned between the front connection member 2a and the back connection member 3a. Unishi may be.

The panel main body 1a is protruded from above, or only one of the front connection member 2a and the rear connection member 3a is attached to the lower panel main body 1a with one end protruding upward. At the same time, either one of the front connection member 2a or the back connection member 3a is integrally formed with the lower panel body 1a and the upper panel body 1a is stacked above the lower panel body 1a. Or after being loaded, the bolt 4a or the nut 5b was loosened and did not protrude from above, or was not attached, or was integral The other of the front connection member 2a or the back connection member 3a that is not molded is attached to the panel body 1a by projecting from the upper side of the lower panel body 1a, and the upper panel is interposed between the front connection member 2a and the back connection member 3a. You may make it position the main body 1a.

  Further, the wall surface is constructed by performing the third step of filling the back surface of the panel body 1a at each stage to a predetermined height with the concrete 15 after the completion of any of the panel stacking cycles of the first and second steps. It may be. Further, after the third step of placing the concrete 15, the first step to the third step described above are performed a predetermined number of times depending on how the concrete 15 is cured without performing the fourth step of removing the front connection member 2 a immediately. It is also possible to employ a configuration in which a fourth step of removing the front connecting member 2a attached to the panel body 1a on the front side of the hardened concrete 15 is performed after the arbitrary step of fully hardening.

  Similarly, in each wall surface construction method described below, the front connecting member 2a and the rear connecting member 3a may be formed integrally with the panel main body 1a when the panel main body 1a is formed. Further, in the first step, the front connecting member 2a and the rear connecting member, which are attached to the lower panel body 1a at the same time as or after the upper panel body 1a is stacked above the lower panel body 1a. The upper panel body 1a may be positioned between the end portions of 3a. Further, in the first step, the front connecting member 2a and the rear connecting member, which are attached to the upper panel body 1a at the same time or after the upper panel body 1a is stacked on top of the lower panel body 1a. The upper panel body 1a may be positioned so that the lower panel body 1a is sandwiched between the end portions of 3a. Moreover, you may make it the structure performed after completion | finish of the arbitrary processes of the panel pile-up cycle by the 1st and 2nd process for the 3rd process filled with the concrete 15. FIG. Similarly, the fourth step of removing the front connecting member 2a may be configured to be performed after the first to third steps are performed a predetermined number of times without being performed immediately after the third step of placing the concrete 15. .

  In the above-described process of stacking the panel main body 1a, a load exerting the upper panel main body 1a to the front side is applied to the upper panel main body 1a from the rear side by the side pressure of the concrete 15 placed on the back side of the panel main body 1a. However, on the front side and the back side of the upper panel body 1a, the upper end of the front connection member 2a and the tip of the bolt 4c receive this load applied in the directions of arrows 9a1 and 9a2 shown in FIG.

The panel main body 1a of the upper panel 1B is inserted between the front connection member 2a and the rear connection member 3a, one end of which is attached to the panel main body 1a of the lower panel 1A. Here, the adjustment material 8a is interposed between the attachment surface of the front connecting member 2a attached to the panel body 1a of the lowermost panel 1A and the front surface of the panel body 1a of the lowermost panel 1A. A predetermined interval 19 is provided between the front surface of the panel body 1a of the adjacent second-stage panel 1B and the engagement surface 2a1 of the front connection member 2a.

  Next, in the second step, one end of the bolt 4c is screwed to the other end of the front connection member 2a having a predetermined interval 19, and the bolt 4c is rotated to move in and out of the engagement surface 2a1 of the front connection member 2a. Thus, the protruding end of the bolt 4c is brought into contact with and engaged with the front surface of the panel body 1a of the upper panel 1B, thereby fixing the panel body 1a.

  Next, in the third step, the back surface of the panel body 1a of the second-stage panel 1B is filled with concrete 15 to a predetermined height B. Next, in the fourth step, after the concrete 15 is cured, the panel of the lowermost panel 1A that engages the panel bodies 1a that are buried to a predetermined height by the concrete 15 whose back surface is cured in the third step. The front connecting member 2a provided on the front surface of the main body 1a is removed. Thereafter, these steps are repeated to construct the wall surface.

  In the above-described process of stacking the panel main body 1a, a load exerting the upper panel main body 1a to the front side is applied to the upper panel main body 1a from the rear side by the side pressure of the concrete 15 placed on the back side of the panel main body 1a. However, on the front side and the back side of the upper panel body 1a, this load is applied in the direction of the arrows 9c2 and 9c3 with the front center of the back connection member 3a contacting the tip of the bolt 4c and the joint of the upper and lower panel bodies 1a. This prevents the upper panel body 1a from falling to the front side. In addition, the load that tilts the upper panel body 1a to the back side due to the weight of the panel body 1a due to the panel body 1a being tilted backward and due to some side pressure applied to the front surface of the panel body 1a is Even if it is applied to the panel main body 1a from the front side, the front end and the rear end of the upper panel main body 1a receive the load applied to the tip of the bolt 4c and the upper end of the rear connecting member 3a in the directions of the arrows 9c2 and 9c1, The upper panel body 1a is prevented from falling to the back side. Also in this case, the nut 5c to which the bolt 4c is screwed is appropriately selected from the three according to the magnitude of the load applied to the front side or the back side of the upper panel body 1a.

  FIG.4 (b) is a partial side view of the wall surface structure constructed | assembled by the wall surface construction method by the 3rd modification of 1st Embodiment. In FIG. 4B, the same or corresponding parts as those in FIG.

  In the second modification of the first embodiment, as shown in FIG. 6A, one end of the front connecting member 2a and the back connecting member 3a is attached to the panel main body 1a and the other end of the panel main body 1a. It protrudes upward from the upper front side and the upper rear side, and is attached to the panel body 1a. However, in the third modification shown in FIG. 5B, one end of the front connecting member 2a and the back connecting member 3a is attached to the panel body 1a, and the other ends are the lower front side and the lower back side of the panel body 1a. The panel body 1a is attached to the panel body 1a. The other configuration is the same as that of the first embodiment.

  In the third modification, in the first step when stacking the panel main bodies 1a in a plurality of stages, the front surface of the lower panel main body 1a and the front connection member 2a whose other end protrudes downward from the front side of the upper panel main body 1a. The lower panel body 1a is inserted between the front connection member 2a and the back connection member 3a, one end of which is attached to the upper panel body 1a, so that a predetermined distance 19 is provided between the engagement surface 2a1 and the engagement surface 2a1. The upper panel body 1a is placed on the lower panel body 1a. Thereafter, the wall surfaces are constructed by the second to fourth steps similar to those of the second modification shown in FIG.

  In the above-described process of stacking the panel main body 1a, a load exerting the upper panel main body 1a to the front side is applied to the upper panel main body 1a from the rear side by the side pressure of the concrete 15 placed on the back side of the panel main body 1a. However, at the front and back of the lower panel body 1a, the front end of the bolt 4c and the center of the front surface of the back connection member 3a contacting the joint of the upper and lower panel bodies 1a receive this load applied in the directions of the arrows 9d2 and 9d1. Thus, the upper panel body 1a is prevented from falling to the front side. In addition, the load that tilts the upper panel body 1a to the back side due to the weight of the panel body 1a due to the panel body 1a being tilted backward and due to some side pressure applied to the front surface of the panel body 1a is Even if it is applied to the panel main body 1a from the front side, the front end and the rear surface of the lower panel main body 1a receive the load applied to the tip of the bolt 4c and the lower end of the rear connecting member 3a in the directions of the arrows 9d2 and 9d3, The upper panel body 1a is prevented from falling to the back side. At this time, the nut 5c to which the bolt 4c is screwed is appropriately selected from the three according to the load applied to the front side or the back side of the upper panel body 1a.

  FIG. 5 is a side view of a wall surface structure completed by stacking a plurality of panels 1A and 1B shown in FIGS. In the figure, the same or corresponding parts as in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is omitted.

  This wall surface structure is an example in which the wall surfaces shown in FIGS. 2 and 4 are paired so that the back surfaces of the panel main bodies 1a face each other. As shown in FIG. 4 described above, a plurality of panels 1A and 1B shown in FIG. Moreover, as shown in FIG. 2 mentioned above, the panels 1A and 1B shown in FIG. A roadway 20 is provided behind the wall surface structure, and a guard rail 21 is provided at the top. When constructing this wall surface structure, a part of the foundation ground 22 ahead is dug down, the crushed stone 16 and the foundation 11 are laid in the dug down part, and the panels 1A and 1B are installed on them.

  According to the wall surface construction method according to the first embodiment and the first to third modifications as described above, the first step has the other end at the lower stage as shown in FIGS. 2 (a) and 4 (a). The upper panel body 1a is inserted and positioned between the front connection member 2a and the rear connection member 3a, which protrudes upward from the front and rear sides of the panel body 1a and has one end attached to the lower panel body 1a. Alternatively, as shown in FIGS. 2B and 4B, the other end protrudes downward from the front side and the back side of the upper panel body 1a, and one end is attached to the upper panel body 1a. The upper panel body 1a is positioned so that the lower panel body 1a is sandwiched between the front connection member 2a and the back connection member 3a. By the second step, the front or back surface and front surface of the upper or lower panel body 1a are positioned. The bolts 4c constituting the support jig are interposed between the engagement surfaces 2a1 and 3a1 at the ends of the connecting member 2a or the back connecting member 3a and the engagement surfaces 2a1 and 3a1, thereby fixing the panel body 1a. Thus, the upper and lower panel main bodies 1a can be supported at a desired position in the extending direction of the wall surface.

  For this reason, when stacking the panel main body 1a, it is possible to pack the panel main body 1a from the end for each step without considering the positional relationship between the upper and lower panel main bodies 1a in the laying extension direction. Accordingly, when the panels 1A and 1B are stacked, the positional relationship between the upper and lower panels 1A and 1B is shifted, so that the bolt holes and connecting holes of the upper and lower panels do not match each other as in the conventional case, and the upper and lower panels are bolted. It will not be impossible to connect the wall with the screw or screw.

  Further, when the panel main bodies 1a are stacked in a plurality of stages, the upper and lower panel main bodies 1a are simply engaged with each other by the front connecting member 2a and the rear connecting member 3a, and the panel main body 1a and the engaging surface 2a1, which have predetermined intervals 19 and 17, By interposing the bolt 4c between 3a1 and 3a1, the upper and lower panel main bodies 1a support each other, and the panel main body 1a becomes independent. For this reason, since the operation | work which fastens the upper and lower panels with a volt | bolt and a screw, and the operation | work which provides the temporary support material etc. which support a panel conventionally performed in order to make panel 1A, 1B self-supporting is unnecessary. Stacking work efficiency is improved. Moreover, since the panel main body 1a can be made thin and simple, the manufacturing cost of the wall surface can be greatly reduced.

  When the upper panel body 1a is stacked on the lower panel body 1a, the upper panel body 1a is guided by the front connection member 2a and the back connection member 3a attached to the lower or upper panel body 1a. Moving. For this reason, the upper panel body 1a is difficult to be shifted to the front side or the back side of the wall surface of the lower panel body 1a, and can be easily installed directly above the lower panel body 1a. Stacking work efficiency is improved. In addition, the configuration in which the front panel connecting member 2a and the back panel connecting member 3a are engaged with the adjacent panel main body 1a is a configuration in which only one of the front panel connecting member 2a and the back panel connecting member 3a is engaged with the adjacent panel main body 1a. In addition, the panel main body 1a can easily stand on its own. As a result, a wall surface construction method is provided in which the work process is simple, the work efficiency is good, and the wall surface on which the panel main body 1a is stable and independent can be constructed.

  In addition, there are predetermined gaps 19 and 17 between at least one of the front surface or the back surface of the panel body 1a and the engagement surfaces 2a1 and 3a1 of the front connection member 2a or the back connection member 3a attached to the adjacent panel body 1a. Since it is configured to be open, when the panel body 1a is inserted into the space between the front connecting member 2a and the back connecting member 3a, a gap is secured. For this reason, the panel main body 1a smoothly moves in the space between the front connecting member 2a and the rear connecting member 3a, and a pattern or the like provided on the surface of the panel main body 1a may be caught and damaged. In addition, the work efficiency of the stacking work of the panel body 1a is improved.

  In addition, when used on the wall surface of a flexible structure such as a reinforced earth method, the upper and lower panel bodies 1a are not rigidly connected with bolts or the like, so that the embankment or the like behind the panel body 1a sinks or deforms. Then, the panel main body 1a can move following the subsidence and deformation. Therefore, as in the conventional wall surface construction method in which the panel main bodies 1a are rigidly connected to each other with bolts or the like, the embankment or the like behind the panel sinks or deforms, and the load is biased to the back of the panel. A flexible and durable wall surface will not be damaged, as a large load is applied locally to the bolts to be connected and it will not be damaged, or a cavity will be formed on the back side of the panel, etc. A wall surface construction method that can be constructed is provided.

  Moreover, according to the wall surface construction method by 1st Embodiment and the 1st-3rd modification, as shown in FIG. 5, the panel main bodies 1a with which the back was hardened to the predetermined height with the concrete 15 was mutually mutually made. The front connecting member 2a to be engaged is removed in the fourth step, and the removed front connecting member 2a is used for connecting the other panel main bodies 1a, so that the number of connecting members required for the construction of the wall surface is reduced. This reduces the manufacturing cost of the wall surface.

The adjusting member 8a is not interposed between the mounting surface of the front connection member 2a to be formed and the front surface of the panel body 1a. However, in the second embodiment shown in FIG. 6, the adjusting material 8a is interposed between the attachment surfaces of the front connecting member 2a and the rear connecting member 3a attached to the panel body 1a and the front and back surfaces of the panel body 1a. It is inserted.

  Moreover, in 1st Embodiment, as shown in FIG. 1, three holes are provided in the other end of the back connection member 3a which protruded upwards, and a hole is provided in the other end of the front connection member 2a which protrudes upwards. Is not provided. However, in the second embodiment shown in FIG. 6, three holes are provided at the other ends of the front connecting member 2a and the rear connecting member 3a protruding upward. Nuts 5c are welded to the three holes of the front connecting member 2a, and bolts 4f and 4g are screwed into the upper and lower nuts 5c. A nut 5c is welded to the three holes of the back connecting member 3a, and a bolt 4h is screwed into the central nut 5c.

  Further, in the second modification of the first embodiment, as shown in FIG. 3, the angle formed by each bent piece of the V-shaped support member 6b fixed to the lower back of the panel body 1a of the lowermost panel 1A is It has an acute angle. However, in the second embodiment shown in FIG. 6, the angle formed by the bent pieces of the L-shaped support member 6c fixed to the lower back of the panel body 1a of the lowermost panel 1C is a right angle.

  Further, in the first embodiment, as shown in FIG. 1, the front connecting member 2a and the back connecting member 3a are arranged on the front and back surfaces of the panel body 1a with a predetermined distance from each other when viewed from the front of the panel body 1a. ing. However, in the second embodiment shown in FIG. 6, the front connecting member 2a and the back connecting member 3a are disposed so as to overlap each other when viewed from the front of the panel body 1a. In the first embodiment, there is no pattern on the front surface of the panel body 1a. However, in the second embodiment, an uneven pattern is provided on the front surface of the panel body 1a.

  FIG. 7A is a side view of the wall surface structure in the process of building up the panels 1C and 1D shown in FIG. 6 by stacking a plurality of stages by the wall surface building method of the second embodiment. In the figure, the same or corresponding parts as those in FIGS. 2 and 6 are designated by the same reference numerals, and the description thereof is omitted.

  When constructing the wall surface, first, in the preparation, the panel body 1a of the lowermost panel 1C is installed on the foundation 11 made of concrete in the front surface of the pier 30a which is an existing structure. At this time, the panel body 1a of the panel 1C is fixed to the base 11 by the L-shaped support member 6c, the scissors 13 and the rust 14. Moreover, the vertical reinforcement 31a by which the lower end was embed | buried in the foundation 11 which consists of concrete is extended and provided in the perpendicular direction.

  Next, in the first step, the panel body 1a of the second panel 1D is stacked on the panel body 1a of the lowermost panel 1C installed. At this time, the front and back surfaces of the panel main body 1a of the upper panel 1D and the front connecting member 2a and the rear connecting member 3a whose other ends protrude upward from the front and back sides of the panel main body 1a of the lower panel 1C. The upper panel is disposed between the front connecting member 2a and the rear connecting member 3a attached to the panel body 1a of the lower panel 1C so that the predetermined distances 19 and 17 are provided between the mating surfaces 2a1 and 3a1. A 1D panel body 1a is inserted. Here, the adjustment material 8a is interposed between the attachment surface of the front connecting member 2a attached to the panel body 1a of the lowermost panel 1C and the front surface of the panel body 1a of the lowermost panel 1C. A predetermined interval 19 is provided between the front surface of the panel body 1a of the adjacent second-stage panel 1D and the engagement surface 2a1 of the front connection member 2a. Further, the adjustment material 8a is interposed between the attachment surface of the back surface connecting member 3a attached to the panel body 1a of the lowermost panel 1C and the back surface of the panel body 1a of the lowermost panel 1C, so that A predetermined interval 17 is provided between the back surface of the panel body 1a of the second-stage panel 1D and the engagement surface 3a1 of the back surface connecting member 3a.

  Next, in the second step, one bolt 4h is interposed between one engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel body 1a of the second-stage panel 1D, and the other of the front surface connecting members 2a. The panel main body 1a of the second-stage panel 1D is fixed by interposing bolts 4f and 4g between the engagement surface 2a1 and the front surface of the panel main body 1a at positions higher and lower than one bolt 4h. Let At this time, the protruding end of the bolt 4f abuts on the joint portion between the patterns on the front surface of the panel body 1a, and the protruding end of the bolt 4g abuts on the pattern on the front surface of the panel body 1a. These bolts 4h, 4f and 4g constitute a support jig. Further, the horizontal reinforcing bar 31b is engaged with the anchor bolt 4b on the back surface of the panel body 1a to fix the horizontal reinforcing bar 31b to the vertical reinforcing bar 31a, and the reinforcing bar 31 composed of the vertical reinforcing bar 31a and the horizontal reinforcing bar 31b is assembled. The panel main body 1a is self-supporting by the front connection member 2a and the back connection member 3a. Further, the anchor bolt 4b on the back surface of the panel main body 1a is engaged with the horizontal reinforcing bar 31b, so that the panel main body 1a is stronger than the case where the protruding anchor bolt 4b is simply embedded in the concrete 15 and fixed. To the concrete 15. Moreover, the assembly accuracy of the reinforcing bar 31 is improved by engaging the horizontal reinforcing bar 31b with the anchor bolt 4b on the back of the panel body 1a that is regularly installed.

  When performing the first step, the bolt 4h is previously projected between the engagement surface 3a1 and the back surface of the panel body 1a, and in the second step, the bolt 4f and the bolt 4g are connected to the engagement surface 2a1. You may make it interpose between the front surfaces of the panel main body 1a. On the contrary, when performing the first step, the bolt 4f and the bolt 4g are previously projected between the engagement surface 2a1 and the front surface of the panel body 1a, and in the second step, the bolt 4h May be interposed between the engagement surface 3a1 and the back surface of the panel body 1a.

  Next, in the third step, the back surface of the panel body 1a of the second-stage panel 1D is filled with concrete 15 to a predetermined height B. Next, in the fourth step, after the above-described concrete 15 is cured, the panel of the lowermost panel 1C that engages the panel bodies 1a that are buried to a predetermined height by the concrete 15 whose back surface is cured in the third step. The front connecting member 2a provided on the front surface of the main body 1a is removed. Thereafter, these steps are repeated to construct the wall surface.

  In the above-described process of stacking the panel main body 1a, even if a load is generated that tilts the upper panel main body 1a to the front side, the tips of the bolt 4f and the bolt 4h are the arrow 9e1 and the arrow on the front and rear surfaces of the upper panel main body 1a. The load applied in the direction of 9e2 is received to prevent the upper panel body 1a from falling to the front side. Further, even when a load that causes the upper panel main body 1a to fall to the back side is generated, the load applied to the front ends and the rear surfaces of the upper panel main body 1a by the bolts 4g and 4h in the directions of the arrows 9e3 and 9e2 is applied. This prevents the upper panel body 1a from falling to the back side.

The panel body 1a of the lower panel 1C is inserted between the attached front connection member 2a and back connection member 3a, and the panel body 1a of the upper panel 1D is placed on the panel body 1a of the lower panel 1C. . Thereafter, the wall surfaces are constructed by the second to fourth steps similar to those of the second embodiment shown in FIG.

  In the above-described process of stacking the panel main body 1a, even if a load that causes the upper panel main body 1a to fall to the front side is generated, the front ends and the rear surfaces of the lower panel main body 1a have the tips of the bolts 4f and 4h at the arrows 9f3 and the arrows. The load applied in the direction of 9f2 is received to prevent the upper panel body 1a from falling to the front side. Even if a load that tilts the upper panel main body 1a to the back side occurs, the front ends of the lower panel main body 1a receive the load applied to the front ends of the bolts 4g and 4h in the directions of the arrows 9f1 and 9f2. Thus, the upper panel body 1a is prevented from falling to the back side.

The front connection member 2a of the lower panel body 1a is removed.

  In this embodiment, the shape of the wall surface structure surrounding the pier 30a is a rectangular parallelepiped shape according to the rectangular cross-sectional shape of the pier 30a. However, when the pier having a circular cross section is surrounded, the shape of the wall surface structure is cylindrical. It becomes a shape. In the present embodiment, the wall surface structure is constructed around the pier 30a. For example, the wall surface structure of the present embodiment is cylindrical on the outer wall facing the cavity of a structure having a cavity inside such as a hole. The structure constructed | assembled in a shape may be sufficient. In this case, the front surface of the panel body faces the cavity side of the structure. Here, when the size of the cylindrical structure is small, the shape of the wall surface formed by the flat panel main body 1a is not a cylindrical shape but a polygonal shape. For this reason, you may make it comprise the panel main body 1a by shape | molding in a curved surface shape according to the bending method of a cylindrical structure.

  Next, in the third step, the back surface of the panel body 1a of the second-stage panel 1D is filled with concrete 15 to a predetermined height B. Next, in the fourth step, after the above-described concrete 15 is cured, the panel of the lowermost panel 1C that engages the panel bodies 1a that are buried to a predetermined height by the concrete 15 whose back surface is cured in the third step. The front connecting member 2a provided on the front surface of the main body 1a is removed. Thereafter, these steps are repeated to construct the wall surface.

  In the above-described process of stacking the panel main body 1a, even if a load that causes the upper panel main body 1a to be tilted to the front side occurs, the front ends of the upper panel main body 1a have their respective ends of the bolts 4f and 4h at the arrows 9g1 and the arrows. By receiving this load in the direction of 9g2, the upper panel body 1a is prevented from falling to the front side. Further, even when a load that causes the upper panel main body 1a to be tilted to the back side is generated, the load applied to the front ends and the rear faces of the upper panel main body 1a by the bolts 4g and 4h in the directions of the arrows 9g3 and 9g2 is applied. This prevents the upper panel body 1a from falling to the back side.

  FIG.10 (b) is a partial side view of the wall surface structure constructed | assembled by the wall surface construction method by the 3rd modification of 2nd Embodiment. In FIG. 4B, the same or corresponding parts as those in FIG.

  In the second modification, as shown in FIG. 5A, the front connecting member 2a and the back connecting member 3a have one end attached to the panel body 1a and the other ends on the upper front side and upper back side of the panel body 1a. It protrudes upward from the side and is attached to the panel body 1a. However, in the third modification shown in FIG. 5B, one end of the front connecting member 2a and the back connecting member 3a is attached to the panel body 1a, and the other ends are the lower front side and the lower back side of the panel body 1a. The panel body 1a is attached to the panel body 1a. The other configuration is the same as that shown in FIG.

  In the third modification, in the first step when stacking a plurality of panel main bodies 1a, the front and rear surfaces of the panel main body 1a of the lower panel 1C and the front side of the panel main body 1a of the upper panel 1D at the other end And the front body connecting member 2a projecting downward from the back side and the engagement surfaces 2a1, 3a1 of the back surface connecting member 3a with a predetermined distance 19, 17 between the one end of the panel body 1a of the upper panel 1D. The panel main body 1a of the lower panel 1C is inserted between the attached front connecting member 2a and rear connecting member 3a, and the panel main body 1a of the upper panel 1D is placed on the panel main body 1a of the lower panel 1C. . Thereafter, the wall surfaces are constructed by the second to fourth steps similar to those of the second modification shown in FIG.

  In the above-described process of stacking the panel main body 1a, even if a load that causes the upper panel main body 1a to fall to the front side is generated, the front ends of the lower panel main body 1a and the tips of the bolts 4f and 4h are indicated by arrows 9h3 and arrows. The load applied in the direction of 9h2 is received to prevent the upper panel body 1a from falling to the front side. Further, even when a load that causes the upper panel main body 1a to fall to the back side occurs, the load applied to the ends of the bolts 4g and 4h in the directions of the arrows 9h1 and 9h2 on the front and rear surfaces of the lower panel main body 1a. This prevents the upper panel body 1a from falling to the back side.

  According to the wall surface construction method according to the second embodiment and the second modification as described above, as shown in FIGS. 7A and 10A, in the second step, the back connection member 3a is engaged. One bolt 4h is interposed between the surface 3a1 and the back surface of the panel body 1a, and a position higher than the one bolt 4h between the other engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1a. The upper panel is positioned in the first step between the front connecting member 2a and the rear connecting member 3a attached to the lower panel body 1a by interposing the bolt 4f and the bolt 4g at the lower position. The main body 1a is fixed.

  For this reason, even if the load which tilts the upper panel main body 1a to the front side due to the lateral pressure of the concrete 15 placed on the rear surface of the panel main body 1a is applied to the upper panel main body 1a from the rear side, Between the engagement surface 2a1 and the front surface of the upper panel body 1a, the bolt 4f interposed at a position higher than one bolt 4h, and the engagement surface 3a1 of the back connection member 3a and the rear surface of the upper panel body 1a. The load in the direction of arrows 9e1, 9g1 and arrows 9e2, 9g2 is received by one bolt 4h interposed therebetween. Further, even if a load that causes the upper panel body 1a to fall to the back side due to some lateral pressure applied to the front surface of the panel body 1a is applied from the front side of the panel body 1a, the upper surface of the engagement surface 2a1 of the front coupling member 2a A bolt 4g interposed between the front surface of the panel main body 1a and a position lower than one bolt 4h, and a single bolt interposed between the engagement surface 3a1 of the back connection member 3a and the back surface of the upper panel main body 1a. The load applied in the directions of arrows 9e3 and 9g3 and arrows 9e2 and 9g2 is received by 4h. As a result, the load applied from both the front side and the back side can be received by the bolts 4f, 4g, and 4h. Therefore, the front and back sides of the panel body 1a, the front connecting member 2a, and the engaging surfaces 2a1 and 3a1 of the back connecting member 3a Even if the predetermined distances 19 and 17 are provided between the panel main body 1a and the panel main body 1a, the panel main body 1a can be securely fixed without falling or wobbling.

  In addition, according to the wall surface construction method according to the first and third modifications of the second embodiment, as shown in FIGS. 7B and 10B, the engagement of the back connection member 3a is performed in the second step. One bolt 4h is interposed between the mating surface 3a1 and the back surface of the panel body 1a, and is higher than one bolt 4h between the other engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1a. Since the bolt 4g and the bolt 4f are interposed at the lower position and the lower position, the lower panel body 1a is positioned in the first step so that the lower panel body 1a is sandwiched between the front connection member 2a and the rear connection member 3a. The upper panel body 1a is fixed.

  For this reason, even if the load that causes the upper panel body 1a to fall to the front side due to the lateral pressure of the concrete 15 placed on the back surface of the panel body 1a is applied to the upper panel body 1a from the rear side, the lower panel body 1a The load applied in the directions of the arrows 9f3 and 9h3 and the arrows 9f2 and 9h2 is received on the front surface and the back surface. Further, even if a load that tilts the upper panel body 1a to the back side due to some lateral pressure applied to the front surface of the panel body 1a is applied to the panel body 1a from the front side, the arrows on the front and back surfaces of the lower panel body 1a Loads in the directions of 9f1, 9h1 and arrows 9f2, 9h2 are received. As a result, the load applied from both the front side and the back side can be received by the bolts 4f, 4g, and 4h. Therefore, the front and back sides of the panel body 1a, the front connecting member 2a, and the engaging surfaces 2a1 and 3a1 of the back connecting member 3a Even if the predetermined distances 19 and 17 are provided between the panel main body 1a and the panel main body 1a, the panel main body 1a can be securely fixed without falling or wobbling.

  Moreover, according to the wall surface construction method by the 2nd, 3rd modification of 2nd Embodiment, as shown to Fig.10 (a) and (b), of the concrete 15 laid in the back surface of the panel main body 1a. Even if a load is applied to the other end side of the front connection member 2a through the panel body 1a due to the side pressure, the bolt 4i, which is a fulcrum provided at one end of the front connection member 2a, is on the opposite side across the attachment location by the bolt 4a. By contacting the front surface of the panel body 1a, this load can be received even at a fulcrum that contacts the front surface of the panel body 1a. Further, even if a load is applied to the other end side of the back surface connecting member 3a via the panel body 1a due to some lateral pressure applied to the front surface of the panel body 1a, the fulcrum provided at one end of the back surface connecting member 3a is caused by the bolt 4b. By contacting the back surface of the panel main body 1a on the opposite side across the mounting location, this load can be received even at a fulcrum that contacts the back surface of the panel main body 1a. For this reason, the load applied to the other end side of the front connecting member 2a or the back connecting member 3a is supported by the mounting location of the front connecting member 2a or the back connecting member 3a and the fulcrum provided at one end thereof, and only at the mounting location. Compared with the case where the front connection member 2a or the back connection member 3a is fixed, the front connection member 2a or the back connection member 3a is securely fixed to the panel body 1a without wobbling.

  In the second embodiment and the first to third modifications, one bolt 4h is interposed between the engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel body 1a, and the front surface connecting member 2a is engaged. Bolts 4f and 4g are interposed between the joint surface 2a1 and the front surface of the panel body 1a at positions higher and lower than one bolt 4h. However, at least one bolt is interposed between the engagement surface 3a1 of the back surface connection member 3a and the back surface of the panel body 1a, so that A configuration may be adopted in which at least two bolts are interposed at a position higher and lower than the one bolt.

The bolt 4h was screwed into the central nut 5c at the other end of 3a. However, in the fourth modification shown in FIG. 11, the bolt 4h is screwed into the central nut 5c at the other end of the front connecting member 2a, and the bolt 4f is connected to the upper and lower nuts 5c at the other end of the rear connecting member 3a. The bolt 4g is screwed.

  FIG. 12A is a side view of the wall surface structure in the process of building up the panels 1C and 1D shown in FIG. 11 by stacking a plurality of stages by the wall surface building method of the fourth modified example of the second embodiment. In the figure, the same or corresponding parts as those in FIGS. 2 and 11 are denoted by the same reference numerals, and the description thereof is omitted.

  In 2nd Embodiment, as shown to Fig.7 (a), the panel main body 1a was piled up by the multistage perpendicular | vertical. However, in the 4th modification shown in Drawing 12 (a), panel main part 1a is piled up in multiple steps diagonally.

  When constructing the wall surface, in the first step, the panel body 1a of the second panel 1D is stacked on the panel body 1a of the lowermost panel 1C installed. At this time, the front and back surfaces of the panel main body 1a of the upper panel 1D and the front connecting member 2a and the rear connecting member 3a whose other ends protrude upward from the front and back sides of the panel main body 1a of the lower panel 1C. The upper panel is disposed between the front connecting member 2a and the rear connecting member 3a attached to the panel body 1a of the lower panel 1C so that the predetermined distances 19 and 17 are provided between the mating surfaces 2a1 and 3a1. A 1D panel body 1a is inserted.

  Next, in the second step, one bolt 4h is interposed between one engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1a, and the other engagement surface 3a1 of the back connection member 3a and the panel The panel main body 1a is fixed by interposing the bolt 4f and the bolt 4g at positions higher and lower than the single bolt 4h between the back surface of the main body 1a. In addition, when performing said 1st process, the volt | bolt 4f and the volt | bolt 4g are made to protrude beforehand between the engagement surface 3a1 and the back surface of the panel main body 1a, and in the 2nd process, the volt | bolt 4h is engaged with the engagement surface 2a1. You may make it interpose between the front surfaces of the panel main body 1a.

  Next, in the third step, the back surface of the panel body 1a of the second-stage panel 1D is filled with concrete 15 to a predetermined height B. Next, in the fourth step, after the above-described concrete 15 is cured, the panel of the lowermost panel 1C that engages the panel bodies 1a that are buried to a predetermined height by the concrete 15 whose back surface is cured in the third step. The front connecting member 2a provided on the front surface of the main body 1a is removed. Thereafter, these steps are repeated to construct the wall surface.

  In the above-described process of stacking the panel main body 1a, even if a load that causes the upper panel main body 1a to fall to the front side is generated, the front ends and the rear surfaces of the upper panel main body 1a are respectively connected with the arrows 9i2 and By receiving this load applied in the direction of 9i3, the upper panel body 1a is prevented from falling to the front side. Further, since the panel body 1a is tilted and stacked, the weight of the panel body 1a causes a load that causes the upper panel body 1a to fall to the back side. The tips of the bolts 4h and 4f receive this load applied in the directions of the arrows 9i2 and 9i1, and the upper panel body 1a is prevented from falling to the back side.

  FIG.12 (b) is a partial side view of the wall surface structure constructed | assembled by the wall surface construction method by the 5th modification of 2nd Embodiment. In FIG. 4B, the same or corresponding parts as those in FIG.

  In the 4th modification of 2nd Embodiment, as shown to the same figure (a), as for the front connection member 2a and the back connection member 3a, one end is attached to the panel main body 1a, and the other end is the panel main body 1a. It protrudes upward from the upper front side and the upper rear side, and is attached to the panel body 1a. However, in the fifth modification shown in FIG. 4B, one end of the front connecting member 2a and the back connecting member 3a is attached to the panel main body 1a, and the other ends are the lower front side and the lower rear side of the panel main body 1a. The panel body 1a is attached to the panel body 1a. The other configuration is the same as the configuration of the fourth modification of the second embodiment.

  In the fifth modification, in the first step when stacking a plurality of panel main bodies 1a, the front and rear surfaces of the panel main body 1a of the lower panel 1C and the front side of the panel main body 1a of the upper panel 1D at the other end And the front body connecting member 2a projecting downward from the back side and the engagement surfaces 2a1, 3a1 of the back surface connecting member 3a with a predetermined distance 19, 17 between the one end of the panel body 1a of the upper panel 1D. The panel body 1a of the lower panel 1C is inserted between the attached front connection member 2a and back connection member 3a, and the panel body 1a of the upper panel 1D is placed on the panel body 1a of the lower panel 1C. . Thereafter, the wall surfaces are constructed by the second to fourth steps similar to the fourth modification shown in FIG.

  In the above-described process of stacking the panel main body 1a, even if a load that causes the upper panel main body 1a to fall to the front side is generated, the front ends and the rear surfaces of the lower panel main body 1a have the tips of the bolts 4h and 4g indicated by arrows 9j2 and 9j1. By receiving this load in the direction of, the upper panel body 1a is prevented from falling to the front side. Further, since the panel body 1a is tilted backward and stacked, even if a load that causes the upper panel body 1a to fall to the back side occurs due to the weight of the panel body 1a, the front and back surfaces of the lower panel body 1a The tips of the bolts 4h and 4f receive this load applied in the directions of the arrows 9j2 and 9j3, so that the upper panel body 1a is prevented from falling to the back side.

  FIG. 13 is a side view of a wall surface structure completed by stacking a plurality of panels 1C and 1D shown in FIG. In the figure, the same parts as those in FIGS. 11 and 12A are denoted by the same reference numerals, and the description thereof is omitted.

  This wall surface structure is an example of a wall surface structure constructed by the wall surface construction method of the fourth modified example of the second embodiment shown in FIG.

  According to such a wall surface construction method according to the fourth modification of the second embodiment, as shown in FIG. 12A, in the second step, the engagement surface 2a1 of the front coupling member 2a and the panel body 1a. One bolt 4h is interposed between the front surface of the rear panel connecting member 3a and the bolt 4f at a position higher and lower than the one bolt 4h between the other engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel body 1a. And the bolt 4g are interposed, the upper panel body 1a positioned in the first step is fixed between the front connection member 2a and the rear connection member 3a attached to the lower panel body 1a. .

  For this reason, even if the load which tilts the upper panel main body 1a to the front side due to the lateral pressure of the concrete 15 placed on the rear surface of the panel main body 1a is applied to the upper panel main body 1a from the rear side, One bolt 4h interposed between the engagement surface 2a1 and the front surface of the upper panel body 1a, and one bolt 4h between the engagement surface 3a1 of the back connection member 3a and the back surface of the upper panel body 1a The load applied in the directions of the arrows 9i2 and 9i3 is received by the bolt 4g interposed at a lower position. Further, the panel body 1a is tilted backward and stacked, and due to the weight of the panel body 1a, and due to some lateral pressure applied to the front surface of the panel body 1a, the load that tilts the upper panel body 1a to the back side is reduced. Even if it hits the main body 1a from the front side, one bolt 4h interposed between the engaging surface 2a1 of the front connecting member 2a and the front surface of the upper panel main body 1a, and the engaging surface 3a1 of the rear connecting member 3a and the upper step The load applied in the direction of the arrow 9i2 and the arrow 9i1 is received by the bolt 4f interposed between the rear surface of the panel main body 1a and a position higher than the one bolt 4h. As a result, the load applied from both the front side and the back side can be received by the bolts 4f, 4g, and 4h. Therefore, the front and back sides of the panel body 1a, the front connecting member 2a, and the engaging surfaces 2a1 and 3a1 of the back connecting member 3a Even if the predetermined distances 19 and 17 are provided between the panel main body 1a and the panel main body 1a, the panel main body 1a can be securely fixed without falling or wobbling.

  Further, according to the wall surface construction method according to the fifth modification of the second embodiment, as shown in FIG. 12B, in the second step, the engagement surface 2a1 of the front connection member 2a and the panel body 1a One bolt 4h is interposed between the front surface and the bolt 4g and the lower position between the other engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel body 1a. By interposing the bolt 4f, the upper panel body 1a positioned so that the lower panel body 1a is sandwiched between the attached front coupling member 2a and rear coupling member 3a is fixed.

  For this reason, even if the load which falls the upper panel main body 1a to the front side is applied to the upper panel main body 1a from the rear side by the lateral pressure of the concrete 15 placed on the rear surface of the panel main body 1a, the lower panel main body 1a The load in the direction of the arrow 9j2 and the arrow 9j1 is received on the front surface and the back surface of the. Further, the panel body 1a is tilted backward and stacked, and due to the weight of the panel body 1a, and due to some lateral pressure applied to the front surface of the panel body 1a, the load that tilts the upper panel body 1a to the back side is reduced. Even when the main body 1a is applied from the front side, the load applied in the directions of the arrows 9j2 and 9j3 is received on the front and back surfaces of the lower panel main body 1a. As a result, the load applied from both the front side and the back side can be received by the bolts 4f, 4g, and 4h. Therefore, the front and back sides of the panel body 1a, the front connecting member 2a, and the engaging surfaces 2a1 and 3a1 of the back connecting member 3a Even if the predetermined distances 19 and 17 are provided between the panel main body 1a and the panel main body 1a, the panel main body 1a can be securely fixed without falling or wobbling.

  In the fourth and fifth modifications of the second embodiment, as shown in FIGS. 12 (a) and 12 (b), between the engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1a. One bolt 4h was interposed, and bolts 4f and 4g were interposed between the engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel body 1a at a position higher and lower than the one bolt 4h. However, at least one bolt is interposed between the engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1a, so that any of the engagement surfaces 3a1 of the back connection member 3a and the back surface of the panel body 1a A configuration may be adopted in which at least two bolts are interposed at a position higher and lower than the one bolt.

  Further, the panel body 1a, the concrete 15 placed on the back surface of the panel body 1a, and the rod-shaped member or wire member inserted into the existing structure or slope on the back surface of the concrete 15, the inserted rod-shaped member or wire The wall surface constituted by the panel main body 1a may be fixed to the existing structure or the front surface of the slope by filling the filler around the shaped member.

  Moreover, the panel main body 1a by the curve construction performed without aligning the positional relationship of the upper and lower panel main bodies 1a by the wall surface construction methods of the second embodiment and the first to fifth modifications shown in FIGS. When the panels are stacked, the panel main body 1a stacked below and the panel main body 1a stacked above are not one surface, and the entrance / exit occurs between the front side or the back side of the upper and lower panel main bodies 1a. Moreover, when constructing an inclined wall surface by stacking the panel main bodies 1a obliquely in curve construction, a gap is generated between the panel main bodies 1a in the laying extension direction. The entrance and exit and the gap will be described with reference to FIG.

  14 (a) and 14 (b) show that the panel 1D used in the wall surface construction method (see FIG. 12 (a)) of the fourth modified example of the second embodiment is stacked in a plurality of stages obliquely by the potato stacking method. It is the side view and top view of the wall surface structure which carried out curve construction, The figure (c) is the top view which looked at this wall surface structure from the wall surface direction upper direction. FIGS. 14D and 14E show that the panel 1D used in the wall surface construction method (see FIG. 12A) of the fourth modified example of the second embodiment is stacked in a slanted manner by a plurality of stages in a staggered manner. It is the side view and top view of the wall surface structure which carried out curve construction, The figure (f) is the top view which looked at this wall surface structure from the wall surface direction upper direction. In the figure, the same or corresponding parts as those in FIG. 12A are denoted by the same reference numerals and the description thereof is omitted. 14A to 14F, the illustration of the pattern provided on the panel main body 1a shown in FIG. 12A is omitted. 14B, 14C, 14E, and 14F, illustration of members such as the front connecting member 2a and the back connecting member 3a that are attached to the panel body 1a is omitted.

  In the wall surface construction method shown in FIGS. 4A, 4B, and 4C, the side seams of the panel bodies 1a arranged in the lower stage and the side seams of the panel bodies 1a arranged in the upper stage are high. The panel main body 1a is stacked in a plurality of stages obliquely by a tube stacking method in which the panel main bodies 1a are stacked in a straight line in the vertical direction. Further, in the wall surface construction method shown in (d), (e) and (f) of the same figure, the joints of the side edges of the panel bodies 1a arranged in the lower stage and the joints of the side edges of the panel bodies 1a arranged in the upper stage The panel main body 1a is stacked in a slanted manner in a plurality of stages by a staggered stacking method in which the panel main bodies 1a are stacked at random without considering the above.

  When the panel main body 1a is stacked in a plurality of stages in a curved construction, the radii drawn by the lower panel main body 1a and the upper panel main body 1a are different. For this reason, when the panel body 1a is stacked in a plurality of stages obliquely by curve construction by the potato stacking method, as shown in FIG. 5B, a gap 41 that extends from the lower part to the upper part of the panel body 1a is formed between the panel body 1a. In this case, it is necessary to fill the gap 41 with a filling concrete or the like, or to process it into a trapezoidal shape having a different size for each stage where the panel body 1a is stacked. In addition, when the panel body is stacked in multiple stages diagonally by curving construction by the staggered stacking method (not shown) that installs the side edges of each panel body to be aligned in a straight line every other step, the panel bodies It is necessary to adjust the positional relationship between the upper and lower panel main bodies 1a in order to align every other joint, and a gap is generated between the panel main bodies 1a in the same manner as the potato stacking method. It is necessary to bury concrete or the like, or to process the trapezoids having different sizes for each stage on which the panel main body 1a is stacked. In this case, the work efficiency is not good. On the other hand, when the panel main body 1a is stacked in a slanted manner by the curved construction by the shift stacking method, the labor of stacking the panel main body by adjusting the positional relationship of the panel main body 1a as in the staggered stacking method is not required. There is no need to fill in the gap between the la and fill it with concrete, or to form a trapezoid with a different size for each step of laminating the panel body 1a. Efficiency is good.

  When the panel main body 1a is stacked in a plurality of stages by curve construction by the potato stacking method, as shown in the same figure (a), (b) and (c), the positional relationship between the upper and lower panel main bodies 1a does not enter or exit. . On the other hand, when the panel main body 1a is stacked in a plurality of stages by curving work performed without aligning the positional relationship between the upper and lower panel main bodies 1a by a shift stacking method or the like, as shown in FIGS. In addition, the lower panel body 1a and the upper panel body 1a are arranged so that their vertical positions are not aligned, and the front and back surfaces of the upper and lower panel bodies 1a are not flush with each other. That is, as shown in the plan view of FIG. 5 (f), the upper panel body 1a indicated by the dotted line and the panel body 1a indicated by the solid line provided in the lower stage are displaced due to the curved construction. The panel main body 1a enters and exits. Further, as shown in the side view of FIG. 4D, when the panel main body 1a is viewed from the side, entry / exit occurs between the front side and the back side of the upper and lower panel main bodies 1a.

  According to the wall construction method of the staggered stacking method shown in FIGS. 4D, 3D and 3F, the panel body without aligning the positional relationship between the upper and lower panel bodies 1a in the curved construction in which the wall extending direction is bent. When laminating 1a, as described above, the panel main body 1a stacked below and the panel main body 1a stacked above do not form one surface, and the entrance and exit occur between the front and back sides of the upper and lower panel main bodies 1a. However, according to this configuration, there is a gap between the front and back surfaces of the panel main body 1a and the engagement surfaces 2a1 and 3a1 of the front connecting member 2a and the back connecting member 3a, whether or not they come in and out. And the front and back surfaces of the panel main body 1a and the engaging surfaces 2a1 and 3a1 of the front surface connecting member 2a and the back surface connecting member 3a are provided by interposing bolts 4f, 4g and 4h constituting the supporting jig in the gap. The panel body 1a can be fixed without hitting it. Similarly, the panel main body 1a having an uneven pattern on the surface can also be fixed. Accordingly, the mounting position of the bolts 4f, 4g, 4h is adjusted according to the direction of the load applied to the panel body 1a, and the number of interposed bolts is adjusted according to the magnitude of the load applied to the panel body 1a. Thus, it is possible to construct a strong wall surface that can freely cope with various situations such as the direction and size of the load applied to the panel body 1a.

  Further, whether or not the entry / exit occurs, a gap is provided between the front and back surfaces of the panel main body 1a and the ends of the front connection member 2a and the back connection member 3a, and bolts 4f, 4g, By interposing 4h, the front and back surfaces of the panel body 1a and the engaging surfaces 2a1 and 3a1 of the front surface connecting member 2a and the back surface connecting member 3a do not collide with each other so that the upper and lower panel bodies 1a can be desired in the direction of extending the wall surface. Therefore, when the inclined wall surface is curved, the panel main body is arranged for each stage by the above-described shift stacking method in which the positional relationship between the upper and lower panel main bodies 1a is not considered in the laying extension direction. By laminating 1a from the end, the panel body 1a can be stacked obliquely without aligning the positional relationship between the upper and lower panel bodies 1a. Accordingly, only a slight gap corresponding to the difference in curvature radius corresponding to the height of the panel main body 1a is generated between the panel main bodies 1a in the laying extension direction. For this reason, as in the prior art, it is no longer necessary to place interstitial concrete that fills the gaps generated between the panel main bodies 1a, or to process a trapezoid with a different size for each stage where the panel main bodies 1a are stacked, The construction work of the interstitial concrete and the processing work of the panel body 1a are reduced, and the work efficiency of the stacking work of the panel body 1a is greatly improved.

  Further, according to the wall surface construction method according to the second embodiment and the first to fifth modifications thereof, the bolts 4f, 4g, and 4h are rotated, and one end is provided on the other end side of the front connection member 2a or the back connection member 3a. The projecting ends of the bolts 4f, 4g, and 4h screwed into and out of the engagement surfaces 2a1, 3a1 are brought into contact with and engaged with the front surface or the back surface of the upper or lower panel body 1a. Bolts 4f, 4g, and 4h are interposed between the front surface or the back surface of the upper or lower panel body 1a having the spacings 19 and 17 and the engagement surfaces 2a1, 3a1, thereby fixing the panel body 1a. For this reason, the upper and lower panel main bodies 1a are adjusted by adjusting the insertion and removal of the bolts 4f, 4g, 4h to the engaging surfaces 2a1, 3a1 of the front connecting member 2a or the rear connecting member 3a that engage with the adjacent panel main bodies 1a. Can be easily supported and engaged without wobbling, and the working efficiency is improved.

  Moreover, according to the wall surface construction method by 2nd Embodiment and its 1st-5th modification, the attachment surface to the panel main body 1a of the front connection member 2a or the back connection member 3a, and the front surface or back surface of the panel main body 1a By interposing the adjusting member 8a between the engagement surfaces 2a1, 3a1 of the front connection member 2a or the back connection member 3a and the adjacent panel body 1a, the predetermined intervals 19, 17 are It adjusts according to the magnitude | size of the exit / entry produced between the panel main bodies 1a, and the protrusion condition of a pattern. By this adjustment, it is possible to avoid collision between the engagement surfaces 2a1, 3a1 of the front connection member 2a or the back connection member 3a and the adjacent panel body 1a.

  Further, according to the wall surface construction method according to the second modification of the second embodiment, as shown in FIGS. 9 and 10, the panel of the attachment portion that is a fixed portion of the back connecting member 3a to the panel body 1a. The thickness of the main body 1a is thicker than the thickness of the adjacent panel main body 1a at the portion facing the engaging surface 3a1 of the back surface connecting member 3a, so that a predetermined interval is provided between the adjacent panel main body 1a and the engaging surface 3a1. 17 is opened. For this reason, it is possible to avoid a collision between the adjacent panel body 1a and the engagement surface 3a1 of the back connection member 3a due to the entry / exit between the upper and lower panel bodies 1a and the unevenness of the pattern. In addition, the panel main body 1a of the attachment part to the panel main body 1a of the front connection member 2a is not interposed between the attachment surface to the panel main body 1a of the front connection member 2a, and the front surface of the panel main body 1a. Is thicker than the thickness of the adjacent panel body 1a at the portion facing the engaging surface 2a1 of the front connecting member 2a, so that a predetermined distance 19 is provided between the adjacent panel body 1a and the engaging surface 2a1. You can also open it. In this case, collision between the adjacent panel body 1a and the engaging surface 2a1 of the front coupling member 2a due to the entry / exit between the upper and lower panel bodies 1a and the unevenness of the pattern can be avoided.

  FIG. 17 is a side view of a wall surface structure completed by stacking a plurality of panels 1C and 1D shown in FIG. In the figure, the same parts as those in FIG. 16A are denoted by the same reference numerals, and the description thereof is omitted.

  Panels 1C and 1D constructed as shown in FIG. 16 are provided on the front surface of the wall surface of the tunnel 30c, and the wall surface of the tunnel 30c is repaired by these panels 1C and 1D. The panel body 1a of the panel 1D at the ceiling portion of the tunnel 30c is firmly fixed to the tunnel 30c by the two bolts 4j through the concrete 15 buried in the back surface of the panel body 1a, so that the ceiling of the tunnel 30c is firmly formed. It is fixed to the part and prevented from falling.

  Here, in the tunnel 30c shown in FIG. 16, since the panel body 1a of the third-stage panel 1D is slightly inclined to the front side in accordance with the wall surface shape of the tunnel 30c, the panel body 1a of the second-stage panel 1D is The bolt 4f and the bolt 4g are attached to the front connecting member 2a, and the bolt 4h is attached to the rear connecting member 3a. However, in the tunnel 30c shown in FIG. 17, the panel body 1a of the third-stage panel 1D is slightly inclined to the back side according to the wall surface shape of the tunnel 30c. Bolts 4h are attached to the front connecting member 2a, and bolts 4f and 4g are attached to the rear connecting member 3a.

  In the sixth and seventh modifications shown in FIGS. 15 to 17, the wall surface of the curved tunnel 30c is repaired by stacking the upper panel body 1a at an angle different from the surface of the lower panel body 1a. . However, the front connecting member 2a or the back connecting member 3a is bent so that the panel main body 1a attached to one end thereof and the panel main body 1a engaged with the other end form a predetermined shape. It may be configured to repair the wall surface of the tunnel 30c. According to this configuration, the panel main body 1a is stacked by using the front connection member or the rear connection member bent so as to form a surface having a desired shape in the adjacent panel main body 1a, thereby forming a desired shape. Wall surfaces can be constructed. For example, when the panel main body 1a is stacked on the front surface of an existing structure such as the tunnel 30c, the front connection is bent so that a surface having the same shape as the wall surface of the existing structure is formed by the adjacent panel main body 1a. By stacking the panel main body 1a using the members or the back connection members, a new wall surface that matches the wall surface shape of the existing structure can be constructed. In particular, this configuration is effective when applied to a wall surface having a curved surface with a small radius and a large curvature.

  Also, the panel body 1a is piled up so as to form a surface having a predetermined shape with the adjacent panel body 1a engaged through the front connection member 2a and the back connection member 3a, and the tunnel body 30c is stacked. The structure which repairs a wall surface may be sufficient. According to this configuration, a wall surface having a desired shape can be constructed by stacking panel bodies that are bent so as to form a desired surface. For example, when the panel body is stacked on the front surface of the existing structure such as the tunnel 30c described above, the panel body is stacked using the panel body bent in the same shape as the wall surface shape of the existing structure. A new wall surface can be constructed according to the shape of the body wall. Also in this case, it is particularly effective to apply this configuration to a wall surface having a curved surface with a small radius and a large bend.

  FIG. 20 is a side view of a wall surface structure completed by stacking a plurality of panels 1E and 1F shown in FIG. In the figure, the same parts as those in FIG.

  This wall surface structure is an example in which the wall surface structure constructed by the wall surface construction method of the above-described third embodiment is constructed on the foundation ground 22 in front of the retaining wall 30d that has become aged or deformed.

  According to the wall surface construction method according to the third embodiment and the first modification thereof, one bolt is provided between the engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1b in the second step. 4k is interposed, and one bolt 4l is interposed at a height different from one bolt 4k between the engagement surface 3a1 of the back surface connecting member 3a and the back surface of the panel main body 1b. 19 (a), it is positioned between the front connecting member 2a and the back connecting member 3a attached to the lower panel body 1b, or attached as shown in FIG. 19 (b).

It is possible to counter the side pressure from the back portion or the like made of the concrete 15 on the side. As a result, the load from the front side can be received by the bolts 4k and 4l and the load from the back side can be received by the weight of the panel body 1b. Further, when the panel main body 1b is stacked and the wall surface is constructed vertically, it is possible to counter the lateral pressure from the front and back surfaces of the panel main body 1b according to the weight of the panel main body 1b standing vertically. For this reason, even if the predetermined intervals 19 and 17 are provided between the front and rear surfaces of the panel main body 1b and the engagement surfaces 2a1 and 3a1 of the front connection member 2a and the rear connection member 3a, the panel main body 1b may fall over. The panel body 1b can be reliably fixed without wobbling.

  In addition, when the panel main body is stacked obliquely without aligning the positional relationship between the upper and lower panel main bodies 1b in curved construction, the panel main body 1b stacked below and the panel main body 1b stacked above are not one side, Intrusion occurs between the front side and the back side of the panel body 1b. Further, when the panel body 1b is stacked with the upper and lower panel bodies 1b aligned, the panel body 1b stacked below and the panel body 1b stacked above do not come and go. It becomes. However, according to this configuration, a gap is formed between the front and back surfaces of the panel main body 1b and the engagement surfaces 2a1 and 3a1 of the front surface connecting member 2a and the back surface connecting member 3a, regardless of whether or not the entry / exit occurs. By providing these bolts 4k and 4l in the gap, the front and back surfaces of the panel main body 1b and the engaging surfaces 2a1 and 3a1 of the front connecting member 2a and the rear connecting member 3a do not collide with each other. Can be fixed. Similarly, the panel main body 1b having an uneven pattern on the surface can also be fixed.

  Also in this configuration, a gap is provided between the front and back surfaces of the panel body 1b and the end portions of the front surface connecting member 2a and the back surface connecting member 3a, and bolts 4k and 4l are interposed in the space so that the panel body The upper and lower panel bodies 1b can be supported at desired positions in the extending direction of the wall surface without colliding with the front and back surfaces of 1b and the engaging surfaces 2a1, 3a1 of the front connecting member 2a and the back connecting member 3a. In the case of curved construction on the inclined wall surface, the panel body 1b is packed from the end for each step without considering the positional relationship between the upper and lower panel bodies 1b in the laying extension direction. The panel main body 1b can be piled up diagonally without aligning. Therefore, only a slight gap corresponding to the difference in curvature radius corresponding to the height of the panel body 1a is generated between the panel bodies 1b in the laying extension direction. For this reason, even with this configuration, as in the prior art, it is possible to place interstitial concrete that fills the gaps generated between the panel main bodies 1a, or to form trapezoids having different sizes for each stage on which the panel main bodies 1a are stacked. This eliminates the need to perform this work, reduces the work for constructing the interstitial concrete and the processing work for the panel body 1a, and greatly improves the work efficiency of the stacking work for the panel body 1b.

  In the present embodiment, in the second step, as shown in FIG. 19, one bolt 4k is interposed between the engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1b, so that the back connection member 3a. In this configuration, one bolt 4l is interposed at a height different from one bolt 4k between the engagement surface 3a1 and the back surface of the panel body 1b. However, at least one bolt is interposed between the engagement surface 2a1 of the front connection member 2a and the front surface of the panel body 1b, and any of the engagement surfaces 3a1 of the back connection member 3a and the back surface of the panel body 1b Alternatively, at least one bolt may be interposed at a height different from that of the one bolt.

Bolts 4f, 4g, and 4h are interposed between the engagement surfaces 2a1 and 3b1 of the 3b, and the panel main body 1c is fixed and stacked. It can be supported at a desired position in the extending direction of the wall surface.

  For this reason, when stacking the panel main body 1c, it is possible to pack the panel main body 1c from the end for each stage without considering the positional relationship between the upper and lower panel main bodies 1c in the laying extension direction. Therefore, when the panels 1G are stacked, the positional relationship between the upper and lower panels 1G is shifted, so that the bolt holes and connecting holes of the upper and lower panels do not match each other, and the upper and lower panels are connected with bolts and screws. You won't be unable to build a wall.
