  When assembling the formwork using separators, not only do you have to install a considerable number of separators per unit area of the plywood board, but also facing each other, taking into account the position of the reinforcing bars so that they do not collide with the reinforcing bars After drilling a through hole in one of the plywood plates, the drilling position of the other plywood plate corresponding to the through hole must be accurately positioned (marking out), and the through hole must be drilled in the plywood plate. Therefore, in order to maintain the parallel state of the veneer plates facing each other using a separator, it is necessary to rely on many years of experience and intuition of the mold carpenter.

  As another example of the present invention, the first mold panel and the second mold panel are hexahedrons having a facing surface, a contact surface, an upper surface, a lower surface, and both side surfaces. Is applied with a polyurea resin that lowers the frictional resistance of the formwork panels to the concrete and increases the strength of the entire formwork panels, and a smooth coating layer of a predetermined thickness is formed from the cured polyurea resin. Formed on the surface.

  Another example of the present invention is a seismic reinforcing wall made of reinforced concrete in which the building is that of an existing building and the reinforcing wall is made in the existing building.

  According to the reinforcing wall construction method according to the present invention, in the mold assembly process, the first to n-th vertical installation members are installed immediately after the first mold panel and immediately before the second mold panel. Even if the lateral pressure of the concrete placed in the inner space between the panels acts on each panel, the first to nth vertical installation members suppress the deformation of the first formwork panel in the front-rear direction and the second mold. Since the forward and backward deformation of the frame panel is suppressed, the first and second formwork panels can sufficiently withstand the lateral pressure of the concrete, and the parallel state between the panels can be maintained. Reinforcement walls can be made at the construction site as designed by the structural calculation. Since the reinforcing wall construction method can maintain the parallel state between the panels by installing the first to nth vertical members, there is no need to install a plurality of separators when assembling the formwork. The labor and time for installing the separator can be saved, and the reinforcing wall can be made efficiently in a short construction period. The reinforcing wall construction method allows an operator other than the mold carpenter to assemble the mold in a short time without relying on an experienced mold carpenter, and the reinforcing wall can be easily and inexpensively made.

  Reinforcing the formwork in a series in the lateral direction by repeating the first vertically fixing material fixing process, the first fixing panel of the formwork panel, the second fixing process of the formwork panel, and the second fixing process of the vertically extending material. In the wall construction method, by repeating these steps, the first and second formwork panels can be arranged in series in the lateral direction, so that the lateral dimensions of the formwork can be extended, and the reinforcement wall to be constructed Forms can be assembled to fit the horizontal dimensions.

  A first horizontal fixing material fixing step of fixing the first to n-th horizontal installation materials to the vertical installation materials while being arranged immediately after the first to n-th vertical installation materials installed immediately after the first formwork panel; A horizontal installation material second fixing step in which the first to nth horizontal installation materials are arranged immediately before the first to nth vertical installation materials installed immediately before the second formwork panel and fixed to the vertical installation materials; In the formwork assembling process, the reinforcing wall construction method including the first to nth horizontal members is arranged immediately after and immediately before the first to nth vertical members, and the horizontal members are fixed to the vertical members. Therefore, even if the lateral pressure of the concrete placed in the inner space between the panels acts on each panel, the horizontal members prevent deformation and bending of the vertical members, and the horizontal members and These vertically installed members suppress the deformation of the first and second formwork panels in the front-rear direction and the front direction. In addition, the first and second formwork panels can sufficiently withstand the lateral pressure of the concrete, and the panels can be maintained in parallel with each other. You can make a wall. Since the reinforcement wall construction method can maintain the parallel state between these panels by installing the first to n-th vertical installation materials and the first to n-th horizontal installation materials, there are a plurality of methods when assembling the formwork. There is no need to install a separator, and it is possible to save time and labor for installing the separator, and a reinforcing wall can be efficiently made in a short construction period. The reinforcing wall construction method allows an operator other than the mold carpenter to assemble the mold in a short time without relying on an experienced mold carpenter, and the reinforcing wall can be easily and inexpensively made.

  In the vertical fixing material second fixing step, at least two vertical installation materials are installed between both side edges extending in the vertical direction of the first formwork panel, and between the side edges extending in the vertical direction of the second formwork panel. In the reinforcing wall construction method in which at least two vertical installation members are installed in the first and second formwork panels, at least three vertical installation members are installed and placed in an inner space between the panels. Even if the side pressure of the concrete acts on each panel, the longitudinal construction material can suppress the deformation of the first formwork panel in the front-rear direction and the longitudinal direction of the second formwork panel. The forward deformation can be suppressed. In the reinforcing wall construction method, by installing at least three longitudinal members on the first and second formwork panels, even if the side pressure of the concrete acts on the first and second formwork panels, the panels are deformed. In other words, the panels can be kept parallel to each other, and a reinforcing wall as designed can be created at the construction location of the building.

  In the first horizontal mounting material fixing step, the horizontal mounting materials are fixed to the vertical mounting materials so that at least one horizontal mounting material is positioned in front of each of the first formwork panels arranged in the vertical direction. In the material second fixing step, the reinforcing wall construction method for fixing the horizontal members to the vertical members so that at least one horizontal member is located in front of each of the second formwork panels arranged in the vertical direction Since at least one horizontal member is located on one first formwork panel and at least one horizontal member is located on one second formwork panel, it was placed in the inner space between the panels. Even if the lateral pressure of the concrete acts on each panel, the first and second molds because the horizontal members and the vertical members suppress the deformation of the first and second formwork panels in the front-rear direction and the front direction. The frame panel is Can withstand the side pressure of the concrete, the panels will not be deformed, the panels can be maintained in parallel, and the reinforced walls as designed by the structural calculation will be created at the building construction site. be able to.

  In the first horizontal fixing material fixing step and the second horizontal fixing material fixing step, the number of first and second horizontal mounting materials installed on the formwork panel positioned vertically below is set to the first number on the formwork panel positioned vertically above. The method of constructing a reinforcing wall more than that of the first and second horizontal members is that the side pressure of the concrete placed in the inner space between the panels acts greatly on the panel located below in the vertical direction. Since there are a large number of first horizontal installation members installed on the panels located, the horizontal installation members and the vertical installation members reliably suppress the deformation of the panel located below in the front-rear direction and the front direction. The second formwork panels can sufficiently withstand the lateral pressure of the concrete, the panels are not deformed, the panels can be maintained in parallel, and the building structure can be maintained. You can make the structure calculated as designed reinforcement wall portion.

  In the first fixing process for the formwork panel and the second fixing process for the vertical installation material, the first formwork panels are connected to the vertical installation material via a predetermined connecting member, and the second fixing process for the formwork panel and the vertical installation material. In the second fixing step, the reinforcing wall construction method for connecting the second formwork panels to the vertical installation members via the connection members includes the first and second formwork panels and the vertical installation materials via the connection members. By connecting them together, it is possible to prevent the panels from falling down during the assembly of the formwork or during the placement of the concrete into the space, and the formwork can be assembled smoothly during the formwork assembly process, and In the setting step, concrete can be smoothly placed in the inner space between the first and second formwork panels.

  A truss structure in which the first to n-th vertical installation members are made up of first and second vertical members that extend straight in the vertical direction and truss members that are positioned between the vertical members and extend in a zigzag direction in the vertical direction. Yes, in the first vertical fixing material fixing step and the second vertical fixing material fixing step, the upper ends of these truss structures are firmly fixed to the upper first mounting position and the upper second mounting position, and the truss structure The reinforcing wall construction method for firmly fixing the lower end portion to the lower first mounting position and the lower second mounting position is a truss structure having a large function of suppressing the movement in the front-rear direction and the front as the first to n-th vertical installation members. By using the object, even if the side pressure of concrete placed in the inner space between the panels acts on each panel, the truss structure reliably deforms the first formwork panel in the front-rear direction rearward 2nd type Since the front and rear deformation of the panel is reliably suppressed, the first and second formwork panels can sufficiently withstand the lateral pressure of the concrete, and the parallel state of the panels can be maintained. Reinforcing walls can be made at the construction site of the design as designed.

  The truss structure includes a dimension adjusting member capable of adjusting the height dimension thereof, and the dimension adjusting member is fixed to the upper first and second mounting positions or the lower first and second mounting positions and the first vertical end. A reinforcing wall that is located on the material side and has an opening that can be adjusted in a vertical fixing position with respect to the first vertical material, and the first vertical material is detachably connected to the dimension adjusting material through the opening. In the construction method, the vertical dimension of the truss structure can be adjusted by the dimension adjusting material. Therefore, the vertical dimension of the truss structure can be matched with the height dimension of the construction part of the reinforcing wall. The structure can be securely fixed at the construction site, and the truss structure can reliably suppress the deformation of the first form panel in the front-rear direction and the deformation of the second form panel in the front-rear direction. Can do.

  A placement window for placing concrete in the inner space is formed in at least one of the first form panel and the second form panel, and a confirmation window for confirming the placement state of the concrete in the inner space is provided in the first form frame. Reinforced wall construction method that is made on at least one of the panel and the second formwork panel, and in the concrete placing process, the concrete is placed in the inner space from the placement opening while confirming the concrete placement state from the confirmation window. The concrete can be easily placed in the inner space using the casting opening made in the formwork panel, and the concrete placement state in the inner space can be confirmed from the confirmation window. Concrete can be reliably placed over the entire space, and a reinforcing wall can be reliably formed at the construction site of the building.

The polyurea resin which reduces the frictional resistance with respect to the concrete of the 1st and 2nd formwork panels and increases the intensity | strength of the whole formwork panel is apply | coated to 6 surfaces of those formwork panels, and the smoothness of predetermined thickness by the hardened polyurea resin is carried out. In the reinforcing wall construction method in which the coating layers are formed on the six surfaces of the formwork panels, a smooth coating layer having a predetermined thickness is formed on the six surfaces of the first and second formwork panels by the cured polyurea resin. Since the frictional resistance against the six-sided concrete is reduced by the above, the first and second formwork panels can be easily removed from the hardened concrete when the formwork is disassembled after curing the placed concrete. . In the reinforcing wall construction method, since the smoothness of the six surfaces of the first and second formwork panels is maintained by the polyurea resin coating layer, the used panels can be used repeatedly, and the cost of the formwork Can be suppressed. In the reinforcing wall construction method, the strength of the first and second formwork panels is increased by the polyurea resin coating layer, and deformation such as buckling, breakage, and bending of the panel during use is prevented. Concrete can be sufficiently retained in the space between the two formwork panels, and a reinforcing wall as designed according to the structural calculation can be made at the construction location of the building.
The method of building a reinforced wall, which is a reinforced concrete seismic reinforcement wall in which the building is an existing building and the reinforcing wall is made on the existing building, is the same as the design calculated for the construction location of the existing building by these processes. A new reinforced concrete seismic reinforcement wall can be newly installed, and a reinforced concrete seismic reinforcement wall can be efficiently made in a short time, and the seismic reinforcement wall can be made inexpensively without requiring labor.

FIG. FIG. 5 shows a state in which the first mold panel fixing step is completed, and FIG. 8 shows a state in which the second mold panel fixing step is completed. 5, 8, and 9, illustration of reinforcing bars arranged in the inner space 40 is omitted.

  After the first truss structure 22a is installed at each of the attachment positions 14 to 17 (after the truss structure first fixing process is completed), the first form panel panel fixing process is performed. In the first formwork panel fixing step, as shown in FIGS. 5 and 9, three first formwork panels 29a to 29c are installed in the order of panel 29c → panel 29b → panel 29a with respect to the first truss structure 22a. To do. In this embodiment, an example is shown in which three panels 29a to 29c are installed. However, depending on the vertical dimension of the seismic reinforcement wall 11 to be constructed and the vertical dimension of the panel, 2 panels may be installed in the vertical direction. There are cases where one panel is installed or four or more panels are installed vertically.

  The first formwork panels 29a to 29c (including the second formwork panels 30a to 30c) have a planar shape having a predetermined thickness dimension formed into a square plate shape. The first formwork panels 29a to 29c are opposed to the second formwork panels 30a to 30c with a predetermined area facing each other, the truss structures 22a to 22f (first vertical members 23) ) Is a hexahedron having a contact surface 31 of a predetermined area, upper and lower surfaces 32 and 33, and both side surfaces 34 and 35. The second mold panels 30a to 30c are opposed to the first mold frame panels 29a to 29c with a predetermined area facing each other. The truss structures 22a to 22f (second vertical members 24) ) Is a hexahedron having a contact surface 31 of a predetermined area, upper and lower surfaces 32 and 33, and both side surfaces 34 and 35.

  There is no particular limitation on the vertical dimension, horizontal dimension, and thickness dimension of the formwork panels 29a to 29c, 30a to 30c, and the lateral dimension and thickness dimension of the seismic reinforcing wall 11 to be constructed are taken into consideration. The dimensions of the panels 29a to 29c and 30a to 30c are determined by the structural calculation. Also, various types of panels 29a to 29c and 30a to 30c having different dimensions can be prepared, and these can be used in an appropriate combination when the mold 10 is assembled.

  The formwork panels 29a to 29c and 30a to 30c are manufactured at the manufacturing plant, transported to the construction site of the earthquake-proof reinforcement wall 11, and then used as they are, or cut into desired dimensions at the construction site. However, it can also be used in accordance with the vertical and horizontal dimensions of the seismic reinforcement wall 11 to be constructed. The reinforcing wall construction method involves processing (cutting) the formwork panels 29a to 29c and 30a to 30c into desired dimensions at the construction site of the seismic reinforcement wall 11, and moving the formwork panels 29a to 29c and 30a to 30c in the vertical direction. Because the dimensions and lateral dimensions can be changed freely, it is more suitable for the vertical and lateral dimensions of the seismic reinforcement wall 11 to be constructed compared to pre-determined formwork members such as steel molds. The seismic reinforcement wall 11 according to the structural calculation can be constructed in the seismic retrofitting of an existing building (building) having different vertical and horizontal dimensions, respectively. .

Located at the bottom of.

  The first to sixth horizontal installation members 45a to 45f are hollow metal tubes having a circular cross section made of metal such as iron, aluminum, brass, and alloy, but metals such as iron, aluminum, brass, and alloy. A hollow metal tube having a quadrangular cross-sectional shape made from the above can be used, and steel materials such as H-shaped steel, I-shaped steel, and square steel can also be used. Note that six first to sixth horizontal members 45a to 45f are installed in front of the first formwork panels 29a to 29c, and six first to sixth sixth form panels 30a to 30c are provided in front of the first formwork panels 30a to 30c.

FIG. 23 is a diagram illustrating an example of the constructed earthquake-resistant reinforcing wall 11. FIG. 21 shows placement of concrete 41 in the inner space 40. FIG. 22 shows a state in which the concrete placing process has been completed, and FIG. 23 shows a state in which the mold form dismantling process has been completed. In FIGS. 21 and 22, illustration of reinforcing bars arranged in the inner space 40 is omitted.

  First and second positioning step, angle first and second installation step, truss structure first fixing step, formwork panel first and second fixing step, truss structure second fixing step, horizontal installation material first and When the second fixing step is completed, the assembly of the mold 10 is finished. Between the first formwork panels 29a to 29c and the second formwork panels 30a to 30c, an inner space 40 having a predetermined volume for placing the concrete 41 is formed. Although not shown, air holes are formed in any of the panels 29a to 29c and 30a to 30c to release air existing in the space 40 when the concrete 41 is placed in the space 40 to the outside.

  After assembling the formwork 10, a concrete placing process is performed. In the concrete placing process, as shown in FIG. 21, concrete 41 is placed in the inner space 40 from a placement opening 42 formed in the second formwork panel 30a. Although the concrete 41 is placed in the space 40 (not shown), a hose extending from the concrete mixer is connected to the placement port 42 of the panel 30a, and the concrete 41 is press-fitted into the space 40 from the placement port 42. The air in the space 40 is exhausted to the outside through the air holes formed in any of the panels 29a to 29c and 30a to 30c. In the concrete placement step, the concrete 41 is placed while visually confirming the space 40 from the confirmation window 43 and using the confirmation window 43 to determine the concrete 41 placement state in the space 40.

  In the concrete placement process, the concrete 41 can be easily placed in the space 40 by using the placement opening 42 formed in the panel 30a, and the concrete is placed at the construction site of the earthquake-proof reinforcement wall 11 inside the building. 41 can be reliably placed. In addition, since the concrete 41 can be placed in the space 40 through the confirmation window 43, the concrete 41 can be reliably placed in the entire space 40, and the concrete 41 is not placed in the space 40. Can be prevented.

  When the concrete 41 is placed in the space 40 by the concrete placing process, the lateral pressure of the concrete 41 flowing into the space 40 acts on the first formwork panels 29a to 29c. When the side pressure of the concrete 12 acts on the panels 29a to 29c, the panels 29a to 29c try to bulge forward in the front-rear direction, but the bulges of the panels 29a to 29c are suppressed by the truss structures 22a to 22c, and the concrete 41 The deformation of the panels 29a to 29c and the collapse of the stacked panels 29a to 29c due to the lateral pressure are prevented. Further, when the lateral pressure of the concrete 41 acts on the panels 29a to 29c, the truss structures 22a to 22c thereby bulge forward in the front-rear direction, but each truss structure is formed by the first to sixth horizontal members 45a to 45f. The bulges of the objects 22a to 22c are suppressed, and deformation and bending of the truss structures 22a to 22c due to the side pressure of the concrete 41 are prevented.

  Further, when the concrete 41 is placed in the space 40 by the concrete placing step, the side pressure of the concrete 41 that has flowed into the space 40 acts on the second formwork panels 30a to 30c. When the side pressure of the concrete 41 acts on the panels 30a to 30c, the panels 30a to 30c try to bulge backward in the front-rear direction, but the bulges of the panels 30a to 30c are suppressed by the truss structures 22a to 22c, and the concrete 41 The deformation of the panels 30a to 30c due to the side pressure and the collapse of the stacked panels 30a to 30c are prevented. Further, when acting on the side pressure panels 30a to 30c of the concrete 41, the truss structures 22a to 22c try to bulge backward in the front-rear direction, but each truss structure is formed by the first to sixth horizontal members 45a to 45f. The swelling of 22a-22c is suppressed, and the deformation | transformation and bending of truss structure 22a-22c by the side pressure of concrete 41 are prevented.

  In the mold 10, the polyurea resin 37 is applied to the six surfaces 31 to 36 of the first and second mold panels 29 a to 29 c and 30 a to 30 c, and the panels 29 a to 29 c and 30 a to 30 c themselves are cured by the cured polyurea resin 37. Since the bending strength is greatly increased, even if the lateral pressure of the concrete 41 acts on the panels 29a to 29c and 30a to 30c, the panels 29a to 29c and 30a to 30c are not bent, and the panels 29a to 29c, The straight state of 30a-30c can be maintained. Further, the strength of the panels 29a to 29c and 30a to 30c is increased by the coating layer of the polyurea resin 37, so that deformation of the panels 29a to 29c and 30a to 30c during use, such as buckling, breakage, and bending, is prevented. The concrete 41 can be sufficiently retained in the space 41 between the panels 29a to 29c and 30a to 30c.

  After placing the concrete 41 in the space 40, the concrete 41 is cured for a predetermined period. After the curing period of the concrete 41 elapses, a mold form dismantling process is performed. In the mold disassembly step, the fixing bracket 46 is removed from the second vertical member 25 of the first to third truss structures 22a to 22c, and the first to sixth horizontal installation members 45a to 45f are removed from the truss structures 22a to 22c. Remove. After the horizontal members 45a to 45f are removed, the connecting cloth string 44 is unwound from the second vertical member 24 of the truss structures 22a to 22c, and the bolt screw holes and dimension adjusting members of the first and third angles 18, 20 are removed. The adjuster bolt is removed from the bolt screw hole of the fixed end portion 26 of the 26, the fixed end portion 27 of the dimension adjusting member 26 and the angles 18, 20 are released, and the bolts of the second and fourth angles 19, 21 are also released. The adjuster bolt is removed from the screw hole and the bolt screw hole at the lower end portion of the first vertical member 23, the lower end portion of the first vertical member 23 and the angles 19, 21 are released, and the bottom or floor of the ceiling beam 13A is removed. The truss structures 22a to 22c are removed from the top surface of the beam 13B.

  After removing the truss structures 22a to 22c, the anchor bolts are extracted from the resin anchors and mechanical anchors of the anchor holes drilled in the lower first mounting position 15 and the lower second mounting position 17 on the top surface of the floor beam 13B. The fixing of the floor beam 13B and the angles 19, 21 is released, and the anchor is made from a resin anchor or a mechanical anchor in an anchor hole drilled in the upper first mounting position 14 or the upper second mounting position 16 on the bottom surface of the ceiling beam 13A. The bolt is pulled out, and the fixation between the ceiling beam 13A and the angles 18 and 20 is released.

  After removing the first to fourth angles 18 to 21, the panels 29a to 29c and 30a to 30c are moved in the front-rear direction while holding the handles 38 of the first and second formwork panels 29a to 29c and 30a to 30c by hand. Pull the panel 29a to 29c, 30a to 30c by pulling forward or backward in the front-rear direction. Since the polyurea resin 37 is applied to the six surfaces 31 to 36 of the panels 29a to 29c and 30a to 30c, and the frictional resistance of the six surfaces 31 to 36 is greatly reduced, the cured concrete 41 after curing is a panel. The panels 29a to 29c and 30a to 30c can be easily detached from the concrete 41 without adhering to the 29a to 29c and 30a to 30c. By removing all the members that form the mold 10 and disassembling the assembled mold 10, a new reinforced concrete seismic reinforcement wall 11 shown in FIG. 23 is formed.

  In the seismic reinforcing wall construction method, the first to third truss structures 22a to 22c (first to nth truss structures) and the first to sixth horizontal members 45a to 45f (first to nth horizontal members) , The lateral pressure of the concrete 41 placed in the inner space 40 between the first and second formwork panels 29a to 29c and 30a to 30c acted on the panels 29a to 29c and 30a to 30c. However, the panels 29a to 29c and 30a to 30c are not deformed, and the formwork 10 can sufficiently withstand the lateral pressure of the concrete 41, and the panels 29a to 29c and 30a to 30c are parallel to each other. Since the concrete 41 placed in the space 40 does not harden in a deformed state, it can be maintained in a new state as designed in the structure of the existing building. It is possible to make the muscle concrete seismic reinforcement wall 11.

  The reinforcing wall construction method does not need to install a plurality of separators when assembling the formwork 10, and can save labor and time for installing the separators, as well as rely on the experience and intuition of formwork carpenters. In addition, the mold 10 can be assembled efficiently in a short time, and the seismic reinforcement wall 11 can be constructed at low cost without requiring labor. In addition, since the reinforcing wall construction method does not require a separator to be installed in the space 40 when the mold 10 is assembled, the separator does not interfere with the reinforcing bars arranged in the space 40 and can be freely placed in the space 40. Reinforcing bars (embedded anchors, vertical bars, horizontal bars, column bars, hoop bars, ribbed bars, diagonal reinforcing bars, etc.) can be arranged, and a strong seismic reinforcing wall 11 made of reinforced concrete can be made. In the reinforcing wall construction method, the strength, smoothness and strength of the six surfaces 31 to 36 of the panels 29a to 29c and 30a to 30c are maintained by the coating layer of the polyurea resin 37, so that the used panels 29a to 29c and 30a to 30a to 30c are maintained. 30c can be used repeatedly, and the cost of the mold 10 can be greatly reduced as compared to a mold that makes the plywood disposable.

  Note that the side pressure of the concrete 41 placed in the space 40 greatly affects the panels 29b, 29c, 30b, and 30c positioned below, but the reinforcing wall construction method is based on the panels 29b and 29c positioned between the middle and the bottom. , 30b, 30c (panels 29b, 29c, 30b, 30c positioned below in the vertical direction), the number of horizontal members installed is larger than that of the horizontal members for the panels 29a, 30b positioned at the top. ~ The panels 29b, 29c, 30b, 30c are reliably swelled in the front-rear direction by the sixth horizontal members 45b-45f, and the panels 29b, 29c, 30b when the concrete 41 is placed in the space 40, The deformation of 30c can be reliably prevented.
