Description

  The present invention relates to a wall structure constructed between upper and lower horizontal members such as beams and girders of a building.

  In recent years, the necessity of thinning has been emphasized for the protection of planted forests and the promotion of forestry, and the promotion of the use of thinned wood cut by thinning has become an important issue. In order to promote the use of thinned wood, wall structures using small diameter trees such as thinned wood have been proposed.

  As a wall structure using this small-diameter tree, conventionally, a cylindrical thinning of a certain length is processed into a wall member having a T-shaped cross section consisting of a base and a protruding part protruding perpendicularly from the center of the base, The wall member is inserted into the required number of reinforcing bars in the vertical direction on the base member inserted through the reinforcing bar, the filling member is filled in the space of each upper and lower wall member generated when the wall member is stacked for each stage, and the nut is placed in the reinforcing bar. And are connected together (see Japanese Patent Application Laid-Open No. 2006-104737, FIG. 6).

  The wall members are stacked one above the other in such a way that the protruding direction of the protruding portion is reversed in each step and the upper end surface of the lower protruding portion and the base bottom surface of the upper wall member are in the same plane. It is what was done. Since the filling member filled in the space between the upper and lower wall surface members is in close contact with a part of the wall surface member, contact between a part of the wall surface member and the air is avoided, and the gap is thereby closed.

  The clogging of the gap makes the wall surface member less susceptible to expansion and contraction due to changes in temperature and humidity, and the gap between the wall surface members is also reduced, so that a wall surface structure excellent in heat insulation and sound insulation can be obtained. Moreover, since the said wall surface structure is comprised by the combination of the wall surface member which processed small diameter trees, such as a thinning material, it is possible to promote utilization of a thinning material.

  By the way, in this wall surface structure, a base member and a wall surface member stacked in a required number of steps are connected and fixed by tightening nuts to reinforcing bars inserted therethrough. It is possible to build between the horizontal members.

  However, when building a wall structure between upper and lower horizontal members such as beams and girders of an existing building, such as repairing a wall structure or renovating a building, the conventional wall structure is applied as the wall structure. Then, it is difficult to stack the wall surface member on the reinforcing bar inserted through the lower horizontal member as the base member, and it is also difficult to connect and fix the reinforcing bar to the upper horizontal member.

  In view of this, an object of the present invention is to easily construct a wall structure between an upper horizontal member such as a beam or girder of an existing building and a lower horizontal member.

  In order to solve the above-described problems, the present invention is configured such that a through-hole provided in a wall member having a certain length is inserted into a pipe so that the pipe cannot rotate, and the wall member is stacked in the vertical direction. A wall body configured to be fitted between the upper horizontal member and the lower horizontal member of the building, and a reinforcing bar having a threaded portion at the upper and lower ends is inserted into the pipe. The reinforcing reinforcing bar includes a long nut provided at an upper end portion thereof and a wedge inserted between the pipes to fix the reinforcing reinforcing rod in a non-rotatable manner. The lower horizontal member is fixed to the upper surface of the reinforcing reinforcing bar. A nut into which a lower end portion of a reinforcing bar is screwed, and the upper horizontal member has a bolt fixed to a lower surface thereof and connected to an upper end portion of the reinforcing reinforcing bar and the long nut, and the upper horizontal member and the The wall body between the lower horizontal member The upper end of the lower horizontal member is screwed at the lower end of the reinforcing bar, the wedge is inserted between the pipe and the reinforcing bar, and the reinforcing bar is fixed in a non-rotatable manner. The bolt of the horizontal member and the reinforcing reinforcing bar of the wall surface body are connected by the long nut.

  According to this configuration, the wall body formed by stacking wall members is fitted between the upper horizontal member and the lower horizontal member of the building, and the reinforcing bars of the wall member are connected to the bolts on the lower surface of the upper horizontal member and the lower horizontal member. Because it is connected to the nut on the top surface of the frame, there is no need to insert the horizontal material in the upper and lower parts of the building through the pipe, and a wall structure is placed between the upper horizontal material and the lower horizontal material in the building. Easy to build.

  In addition, the wall member includes a base having a required thickness with a split small-diameter tree obtained by dividing a cylindrical small-diameter tree of a certain length in half in the length direction, and the center of the base. The base is formed in a T-shaped cross section that protrudes in a direction orthogonal to the base, and the thickness of the base is smaller than half of the height of the protrusion, and is based on the bottom of the base A through-hole is provided in the thickness direction of the protrusion at the midpoint of the upper end surface of the protrusion, and the wall surface body is arranged in a posture in which the base bottom surface of the wall member is vertical and the protrusion is horizontal. In addition, the upper base side surface is placed on the lower projecting portion side surface, the projecting direction of the projecting portion is reversed for each step, and the upper end surface of the lower projecting portion and the upper base bottom surface belong to the same plane. The wall members are stacked in a state where they are aligned vertically. It is possible to adopt a configuration in which the space between the upper and lower wall surface members generated at the time of stacking by one stage is filled with a filling member such as wall soil and the uppermost wall surface member is detachably provided. it can.

  According to this configuration, since the uppermost wall member is detachably provided, the long nut that connects the upper end of the reinforcing bar and the bolt of the upper horizontal member with the uppermost wall member removed. These can be connected by operating. For this reason, the assemblability of the wall surface body is good.

  In addition, the wedge is a cylindrical body inserted through the reinforcing reinforcing bar, and if the outer peripheral surface is formed so as to reduce in diameter downward, the wedge and the reinforcing reinforcing bar are driven by driving the wedge. Since the wedge can be inserted into the entire circumference between the reinforcing bars, the reinforcing bars are surely incapable of rotating in the pipe.

  A plurality of the wall surface members are arranged in the lengthwise direction at each step, and each wall surface member is arranged in a staggered manner by shifting the distance of half of the length of the wall surface member one step at a time. It can also be set as the structure made.

  As described above, in this invention, a wall body made up of wall members inserted vertically through a pipe is fitted between an upper horizontal member and a lower horizontal member of an existing building, and these horizontal members are fitted. The wall structure can be easily constructed between the upper horizontal member and the lower horizontal member of the existing building.

  A first embodiment of the present invention is shown in FIGS. As shown in FIGS. 1 and 2, the wall surface structure of this embodiment includes a wall member 12 having a T-shaped cross section between an upper horizontal member 10 and a lower horizontal member 11 such as a beam or a girder of a building. The wall member 15 formed by stacking a plurality of wall members 12 in the vertical direction is inserted into the pipe 14 through which the reinforcing bar 13 passes, and the reinforcing bar 13 is fixed to the nut 16 fixed to the upper surface of the lower horizontal member 11. The bolt 18 fixed to the upper horizontal member 10 and the reinforcing reinforcing bar 13 are connected by a long nut 19 in a state where the reinforcing reinforcing bar 13 is fixed by screwing and driving a wedge 17 between the pipe 14 and the reinforcing reinforcing bar 13. is there.

  As shown in FIG. 3, the wall surface member 12 is obtained by processing divided small-diameter trees 32 and 32 obtained by dividing a cylindrical small-diameter tree 31 having a constant length L in half in the length direction. As shown in FIG. 4A, the wall surface member 12 formed from the divided small-diameter tree 32 includes a base portion 35 having a constant thickness a having a bottom surface 34 as a major part of the dividing surface 33 of the divided small-diameter tree 32, The cross section is formed into a T-shaped cross section including a protruding portion 36 having a height b protruding from the center of the base portion 35 at a right angle.

  The thickness a of the base 35 is formed to be less than half of the height b of the protrusion 36, and the upper surface of the base 35 and the upper end surface 37 of the protrusion 36 are parallel to the dividing surface 33 (bottom surface 34). In addition, the side surface 38 of the base portion 35 and the side surface 39 of the protruding portion 36 are formed so as to be orthogonal to the dividing surface 33. As shown in FIG. 5, the wall surface member 12 is used in a posture in which the bottom surface 34 of the base portion 35 is vertical and the side surface 39 of the protruding portion 36 is horizontal.

  The thickness a of the base portion 35 of the wall member 12 is formed to be equal to or less than half the height b of the protruding portion 36, as shown in FIG. 4B, on the side surface 39 of the protruding portion 36. When the side surfaces 38 are abutted and the upper end surface 37 of the lower protruding portion 36 and the bottom surface 34 of the upper base portion 35 are vertically aligned so as to be in the same plane, they are placed between the upper and lower wall surface members 12. This is because a space 41 with a constant interval d surrounded by the base portion 35 and the protruding portion 36 is formed.

  Further, as shown in FIG. 4A, a through hole 42 is formed in the protruding portion 36 in the thickness direction at an intermediate point of the height c of the upper end surface 37 of the protruding portion 36 with respect to the bottom surface 34 of the base portion 35. Provided. As shown by the one-dot chain line in FIG. 6, the through-hole 42 is located at a distance e from the both end faces of the wall surface member 12 and at a distance e on both sides across the center line 43 of the wall surface member 12. And a total of four locations.

  The through holes 42 are provided at predetermined positions of the wall surface member 12 as described above, when a plurality of wall surface members 12 are arranged in the length direction with their end surfaces abutting each other, with the end surfaces of the wall surface members 12 sandwiched therebetween. This is because the pair of through-holes 42 that are separated from each other by the distance e is arranged for every half length L / 2 of the wall surface member 12. With the arrangement of the pair of through holes 42, a wall surface structure in which the wall surface members 12 are combined in a staggered manner can be configured as in an embodiment described later.

  The wall surface body 15 is mainly configured by combining the wall surface member 12, and wall surface end members 12a and 12b having an L-shaped cross section are used as auxiliary members. As shown in FIG. 7A, the wall surface end member 12 a has a part of the base portion 35 of the wall surface member 12 cut along a surface along one side surface 39 of the protruding portion 36. Similar to the member 12, a through hole 42 is provided.

  Further, as shown in FIG. 7B, the wall surface end member 12 b has a through hole 42 in the wall surface end member 12 a as a notch 44 extending to the upper end surface 37 of the protruding portion 36. By providing this notch 44, the wall surface end member 12 b is detachably attached to the uppermost stage of the wall surface body 15 by fitting the reinforcing bar 13 into the notch 44.

  The pipe 14 is made of aluminum, and as shown in FIG. 8, the outer diameter of the pipe 14 has a size suitable for the through hole 42 of each wall surface member 12. When the through-hole 42 of the wall surface member 12 is inserted into the pipe 14, the pipe 14 becomes non-rotatable due to frictional resistance between the inner surface of the through-hole 42 and the outer diameter surface of the pipe 14.

  The reinforcing reinforcing bar 13 inserted into the pipe 14 is an iron shaft, has a threaded portion at the upper and lower end portions thereof, a long nut 19 provided at the threaded portion of the upper end portion, and the long nut 19 Are provided with a locking nut 20 for restricting the downward movement of the screw and a cylindrical wedge 17 (see FIG. 9). The wedge 17 is formed so that the outer peripheral surface is reduced in diameter downward, and the lower end portion is provided so as to be inserted between the pipe 14 and the reinforcing reinforcing bar 13. By inserting the wedge 17, the reinforcing steel bar 13 becomes non-rotatable in the pipe 14.

  As shown in FIG. 8, the wall surface body 15 formed by stacking the wall surface members 12 in a plurality of stages in the vertical direction is arranged in a posture in which the protruding portion 36 side surface 39 of the wall surface end member 12a faces downward, and the wall surface end member 12a. The through hole 42 is inserted into the pipe 14. On the wall surface end member 12a, the bottom surface of the base portion 35 of the wall surface member 12 is arranged so that the bottom surface is vertical and the projection portion 36 is horizontal, and the upper base portion 35 side surface 38 is on the side surface 39 of the lower projection portion 36. The protrusions 36 are aligned vertically so that the protrusion direction of each protrusion is opposite to each other and the upper end surface 37 of the lower protrusion 36 and the bottom surface 34 of the upper base 35 belong to the same plane (FIG. 4B). )), The required number of stages are sequentially inserted into the pipe 14. As shown in FIG. 9, the wall surface end member 12 a passes through the through hole 42 of the reinforcing reinforcing bar 13 on the protruding portion 36 side surface 39 of the wall surface member 12 inserted through the base 35 side surface 38 of the wall surface end member 12 a. And stacked vertically. Further, the space 41 between the upper and lower wall surface members and the wall surface end member 12a generated when the wall surface member 12 and the wall surface end member 12a are stacked one by one is filled with a filling member 45 such as wall soil or putty. (See FIG. 10).

The wall surface structure is configured as described above, and the assembling procedure will be described with reference to FIGS.
First, as shown in FIG. 8, the wall surface end member 12 a is arranged in a posture in which the side surface 39 faces downward, and the through hole 42 of the wall surface end member 12 a is inserted into the pipe 14 through which the reinforcing steel bars 13 have passed. By inserting the through-hole 42 into the pipe 14, the pipe 14 becomes non-rotatable.

  Next, the wall surface member 12 extends the through hole 42 to the reinforcing reinforcing bar 13 so that the base portion 35 side surface 38 of the wall surface member 12 rides on the protruding portion 36 side surface 39 of the wall surface end member 12a on the wall surface end member 12a. It is inserted. A space 41 formed between the wall surface member 12 and the wall surface end member 12 a is filled with a filling member 21 such as wall soil and putty avoiding the reinforcing bars 13.

  The through holes 42 of the wall surface member 12 are inserted into the reinforcing reinforcing bars 13 in the reverse direction so that the base surface 35 side surface 38 of the upper wall member 12 is placed on the protruding portion 36 side surface 39 of the lower wall member 12. Further, the wall member 12 is stacked in a required number of steps in the vertical direction so that the upper end surface 37 of the lower protrusion 36 and the bottom surface 34 of the upper base 35 belong to the same plane. In the same manner as described above, the space 41 between the upper and lower wall surface members 12 generated when the wall surface members 12 are stacked one by one is filled with the filling member 21 such as wall soil and putty, avoiding the reinforcing reinforcing bars 13.

  Further, as shown in FIG. 9, the wall surface end member 12a passes through the wall surface end member 12a so that the base portion 35 side surface 38 of the wall surface end member 12a is placed on the protruding portion 36 side surface 39 of the uppermost wall surface member 12 stacked in the required number of steps. The hole 42 is inserted into the reinforcing steel bar 13. The space 41 formed between the uppermost wall member 12 and the wall surface end member 12 a is also filled with the filling member 21 such as wall soil and putty avoiding the reinforcing reinforcing bars 13.

  In this way, the wall members 12 and 12a stacked in the required number of steps are integrated by being inserted into the pipe 14, and as shown in FIG. 10, a cylindrical wedge is formed on the upper end of the reinforcing bar 13 penetrating the pipe 14. 17, the lock nut 20 and the long nut 19 are attached to form the wall surface body 15.

  Next, as shown in FIG. 11A, a bolt 18 having a head of a wood screw fixed coaxially to the head is fixed to the recess provided on the lower surface of the upper horizontal member 10 by the wood screw. Further, the nut 16 is fixed to a recess provided on the upper surface of the lower horizontal member 11 so as to be coaxial with the bolt 18 in the vertical direction. The nut 16 only needs to be fixed in a non-rotatable state with respect to the concave portion of the lower horizontal member 11, and as a fixing means, for example, a ring body is fitted to the outer periphery of the nut 16, and the ring body and the nut A wood screw is fixed between 16 and fixed by the wood screw, or the shape of the recess of the lower horizontal member 11 is formed into a square cross section, and the outer periphery of the nut 16 and the inner surface of the recess What is fixed by restricting rotation so as to abut can be adopted.

  Subsequently, the upper horizontal member 10 and the lower horizontal member are arranged on the wall surface 15 so that the reinforcing reinforcing bars 13 are coaxial with the bolts 18 of the upper horizontal member 10 and the nuts 16 of the lower horizontal member 11. (See FIG. 11B).

  The long nut 19 of the fitted wall body 15 is first rotated so as to move downward, butts against the locking nut 20 and screwed further. At this time, since the rotation of the long nut 19 is restricted by the lock nut 20, the reinforcing reinforcing bar 13 rotates together with the screwing of the long nut 19, and the reinforcing reinforcing bar 13 is screwed into the nut 16 of the lower horizontal member 11. Thus, the reinforcing steel bar 13 and the nut 16 are coupled.

  Thereafter, a cylindrical wedge 17 inserted through the reinforcing bar 13 is driven into the pipe 14, and the reinforcing bar 13 is fixed in a non-rotatable state by the wedge 17. In this fixed state, the long nut 19 is rotated so as to move upward, and is screwed into the bolt 18 of the upper horizontal member 10 to connect the bolt 18 and the reinforcing reinforcing bar 13 (see FIG. 11C).

  After the reinforcing reinforcing bars 13 are connected, as shown in FIG. 11 (d), a pair of wall surface end members 12 b are formed between the upper wall surface end members 12 a and the upper horizontal member 10, and the protruding portions 36 are mutually reinforcing reinforcing bars. 13 so that the protruding portion 36 of one wall surface end member 12b is in contact with the base portion 35 of the other wall surface end member 12b, and the notch 44 of each wall surface end member 12b is in that position. The reinforcing reinforcing bars 13 are fitted to each other, and the pair of wall surface end members 12b are fixed to each other with wood screws (see FIG. 11 (e)).

  The wall surface structure of the first embodiment configured as described above is finished as a wall surface structure having a length L and a thickness c corresponding to the height c of the upper end surface 37 of the protrusion 36 (see FIGS. 1 and 2). ). Thereby, it is not necessary to insert the upper horizontal member 10 and the lower horizontal member 11 such as beams and girders of the existing building through the pipe 14 (reinforcing reinforcing bar 13), and the wall surface body made of the wall surface member 12 therebetween. 15 can be fitted and fixed together. For this reason, the wall structure can be easily constructed between the upper horizontal member 10 and the lower horizontal member 11 of the existing building when the wall structure is repaired or the building is renovated.

  Further, in this wall surface structure, the wall surface body 15 is formed by integrating a wooden wall surface member 12 into a pipe penetrating the reinforcing reinforcing bar 13 and inserting the pipe in a non-rotatable state and stacking a required number of steps. For this reason, the position displacement of each wall surface member 12 with respect to the pipe 14 hardly occurs, and the wall surface body 15 is firmly integrated. By connecting and fixing the wall body 15 between the upper horizontal member 10 and the lower horizontal member 11, a wall structure having excellent earthquake resistance and wind resistance is obtained.

Next, Embodiment 2 regarding a wall surface structure will be described based on FIGS. 12 and 13.
The wall surface structure of the second embodiment also uses the wall surface member 12 and the wall surface end members 12a and 12b described above. In this case, the wall surface member 12 and the wall surface end members 12a and 12b have a constant length L, Half length L / 2 is used. The arrangement in the vertical direction of the wall surface structure of the second embodiment is the same as that of the wall surface structure of the first embodiment.

  As shown in FIG. 12, the arrangement in the length direction is such that a predetermined number of wall members 12 and wall end members 12a and 12b having a fixed length L are arranged with their end faces butted in the length direction. The wall surface members 12 are arranged with the required number of end surfaces thereof being abutted for each step, and the wall surface members 12 having a length L / 2 are abutted with the end surfaces of the arranged end surfaces. The wall members 12 of length L / 2 arranged at one end for each step are alternately arranged so as to be the right end and the left end of each wall member 12 arranged in the length direction, and each wall member 12 of each wall member 12 is arranged step by step. The butted surfaces are shifted by a distance L / 2 that is half the length L of the wall surface member 12 and the wall surface end members 12a and 12b.

  Further, as described above, the wall surface members 12 arranged in the length direction are provided with a pair of through holes 42 that are separated from each other by a distance 2e for each distance of the length L / 2 that is half of the wall surface member 12. (See FIG. 6). For each step, the abutting surface of the wall surface member 12 is shifted by a distance L / 2 that is half the length L of the wall surface member 12, and the through holes 42 of the wall surface member 12 are aligned. Thereby, the wall surface member 12 and the wall surface end member 12a arranged in the length direction can pass through the through-hole 42 to the reinforcing reinforcing bar 13, and each wall surface member 12 and each wall surface end member 12a, 12b are staggered as a whole. The wall surface structure can be made to have a desired length.
