It is a front view of the board wall 111 of the past (comparative example). It is a front view of the board wall 111 which shows a diagonal compression phenomenon.

=== This Embodiment ===
1A and 1B are explanatory views of the plate wall 11 according to the present embodiment. In FIG. 1A, the left half of the plate wall 11 is shown in front view, and the right half of the plate wall 11 is shown in center longitudinal sectional view. 1B is a cross-sectional view taken along the line BB in FIG. 1A.

In the following, the three directions orthogonal to each other are defined as a wall height direction, a wall width direction, and a wall thickness direction of the plate wall 11. Here, the wall height direction is the vertical direction, which is the vertical direction, and the wall width direction and the wall thickness direction are respectively horizontal. The wall width direction is also referred to as the left-right direction, and the wall thickness direction is also referred to as the front-rear direction.
Moreover, in FIG. 1A and FIG. 1B, the cross-sectional part which should be originally shown by hatching is also shown without hatching in order to prevent the complication of a figure.

  The building of this embodiment is a wooden building, and the wooden frame has a pair of left and right columns 1 and 1 (corresponding to a vertical member) and a pair of upper and lower beams 3 and 3 (corresponding to a horizontal member). ing. The lower beam 3 may be a ground cover. Moreover, although the pillar 1 and the beam 3 are cocoons, for example, wood other than this may be sufficient. The column 1 and the beam 3 are connected and fixed in a mutually non-movable manner by an appropriate fitting structure such as a mortise and a mortise at the end portions 1e and 3e and a plug 4 so that the rectangular frame A rectangular space when viewed from the front is sectioned inside the wooden frame.

  A plate wall 11 is provided in the rectangular space. The plate wall 11 has a plurality of substantially rectangular plate members 15, 15. Each plate 15 is in contact with the plate 15 adjacent to the upper and lower sides at a small end (kob) 15k, with the longitudinal direction thereof being directed to the left and right horizontal directions and the width direction being directed to the vertical direction. The plate members 15, 15... Are arranged in an aligned manner with the vertical direction, which is a direction perpendicular to the longitudinal direction, as the alignment direction.

  Moreover, the fitting convex part 17 or the fitting recessed part 18 is formed in the upper end surface 15u and the lower end surface 15d which are the small ends 15k of each board | plate material 15, respectively. And the fitting recessed part 18 or the fitting convex part 17 is formed in the small end 15k of the board | plate material 15 adjacent to the upper direction and the downward direction corresponding to said fitting convex part 17 or the fitting recessed part 18. As shown in FIG. By fitting the fitting protrusions 17 and the fitting recesses 18 corresponding to each other, the plate members 15 adjacent to each other in the vertical direction are sequentially connected together to integrate all the plate members 15, 15. As a single earthquake-resistant plate wall 11. The details of the fitting convex portion 17 and the fitting concave portion 18 will be described later.

  The plate wall 11 is fixed to the columns 1 and 1 by, for example, a fitting structure such as a tenon 15h and a tenon 1h. That is, a tenon 15h is integrally formed at each of the end portions 15e and 15e in the left and right direction, which is the longitudinal direction of each plate member 15, and correspondingly, on the bottom surface of the groove-like large case 1t of the column 1 A mortise 1h is formed. Then, in a state where the left and right end portions 15e, 15e of the plate member 15 are in the large insertion 1t of the column 1, the tenon 15h of each end portion 15e, 15e is fitted into the tenon 1h on the bottom surface of the large insertion 1t. Thus, the pillar 1 and the plate wall 11 are connected to each other in a state in which a vertical shearing force can be transmitted.

  Similarly, the plate wall 11 is fixed to the beams 3 and 3 by a fitting structure such as a tenon 15h1 and a tenon 3h. That is, a tenon 15h1 is integrally formed on the upper end surface of the upper end plate member 15 and the lower end surface of the lower end plate member 15, respectively. , 3t are respectively formed with mortises 3h. Then, in a state where the upper end surface of the upper plate member 15 is in the large insertion 3t of the upper beam 3, the tenon 15h1 of the upper end surface fits into the mortise 3h on the bottom surface of the large insertion 3t, and the lower end surface of the lower plate member 15 However, the tenon 15h1 on the bottom surface of the lower beam 3 is fitted in the mortise 3h on the bottom surface of the large beam 3t in the state where the lower beam 3 is in the large case 3t. The plate wall 11 is connected in a state where a horizontal shearing force can be transmitted.

  In the example of FIG. 1A, except for the plate member 15 at the upper end and the plate member 15 at the lower end, the planar shapes of the plate members 15, 15... Positioned between them are the same every other vertical direction. . That is, these plate materials 15, 15... Are roughly classified into two types of outer shape plate materials 15 in consideration of the shapes of the fitting convex portion 17 and the fitting concave portion 18. More specifically, there are two types: the second, fourth, sixth and eighth plate 15 groups from the top, and the third, fifth and seventh plate 15 groups from the top. The outline shape is roughly divided. However, it does not have to be roughly divided into two types. That is, the plate members 15, 15... Do not have to have the same shape every other one in the vertical direction. For example, the width dimension (length in the vertical direction in the example of FIG. 1A) and the plate thickness (FIG. 1B). In this example, the length in the front-rear direction) may be different for each plate material.

FIG. 2 is an explanatory diagram of the fitting convex portion 17 and the fitting concave portion 18, and shows the central portion of the plate wall 11 in an enlarged front view.
The fitting convex part 17 and the fitting concave part 18 which connect the board | plate materials 15 and 15 integrally are each formed in integral with the small end 15k of the board | plate material 15 as a part of board | plate material 15, respectively. In other words, the fitting convex portion 17 is protruded at the small end 15k of the plate material 15 by cutting out the peripheral portion thereof, while the fitting concave portion 18 has a part of the plate material 15 fitted to the fitting convex portion. It is recessed at the small end 15k by being cut out in the shape of 17 or a similar shape. And the dimension of the fitting convex part 17 is formed in the same dimension as the fitting recessed part 18, or slightly larger, and a clearance gap is not formed between each other at the time of a fitting. Therefore, on the basis of the fitting, the upper plate member 15 and the lower plate member 15 are integrated in a state in which the relative movement in the horizontal direction, which is the longitudinal direction, is restricted. Then, the fitting is sequentially repeated with respect to all the plate members 15, 15... Arranged in the vertical direction, and as described above with reference to FIG. 1A, all the plate members 15, 15. The plate wall 11 is formed to receive horizontal external force such as seismic force input from the pillar 1 and the beam 3 to enhance the earthquake resistance of the wooden building.

  In addition, the shape of the fitting convex part 17 and the fitting recessed part 18 is each maintained in the same shape in any cross section over the full thickness of a wall thickness direction (direction which penetrates the paper surface of FIG. 2). Therefore, when making it fit, it can be made to fit easily by sliding in the wall thickness direction in the state which the fitting convex part 17 and the fitting recessed part 18 piled up in the front view.

By the way, as mentioned above, the reason for using the fitting structure which consists of the fitting convex part 17 and the fitting recessed part 18 without using the dowel 121 (FIG. 9) for connection of board | plate materials 15 and 15 in this embodiment. This is for improving the yield strength of the plate wall 11. This will be described in detail below.
3 is a part of the plate 15 that is inseparably integrated with the plate 15 for one plate 15 (the lower plate 15 in FIG. 3). Therefore, by directly engaging the plate materials 15, 15, it is possible to secure a large shear load area with respect to the horizontal force, and as a result, the plate materials 15, 15 adjacent to each other in the vertical direction even under the action of a large horizontal external force It becomes difficult to relatively move in the horizontal direction, and the horizontal strength as the plate wall 11 is improved. It has also been confirmed by experiments described later that the in-plane shear rigidity and proof stress as the plate wall 11 are improved.

  In the example of FIG. 2, one end surface 17 e 1 in the left-right direction of the fitting convex portion 17 is formed on a vertical plane orthogonal to the left-right direction, and the other end surface 17 e 2 in the same direction is formed from the tip 17 s of the fitting convex portion 17. It forms in the taper surface so that the length of the left-right direction of the fitting convex part 17 may become short toward the base end 17b. And if comprised in this way, the board | plate materials 15 and 15 will be firmly connected by the said taper surface 17e2 in the said alignment direction so that separation is impossible, and this can improve the integrity of the board wall 11. On the other hand, the one end surface 17e1 of the fitting convex portion 17 is not a tapered surface as described above but a vertical surface. Therefore, when fitting the fitting convex part 17 and the fitting concave part 18, it becomes easy to make it fit.

  In some cases, the one end surface 17e1 of the fitting convex portion 17 may also be a tapered surface having a reverse gradient with respect to the other end surface 17e2, that is, the tapered surfaces having the opposite inclination to each other are formed on the left and right sides of the fitting convex portion 17. You may form in the both end surfaces 17e1 and 17e2 of a direction. In this case, the workability of the fitting work is inferior to that of the above-described configuration, but the integrity of the plate wall 11 can be improved as compared with the above.

Furthermore, in the example of FIG. 2, both the fitting convex part 17 provided with the above-mentioned taper surface 17e2 and the fitting concave part 18 in which this fitting convex part 17 can be fitted are formed in each small end 15k. ing. That is, the part which is not the fitting convex part 17 in the small end 15k becomes the fitting concave part 18, whereby the fitting convex part 17 and the fitting concave part 18 are alternately arranged in the left-right direction (longitudinal direction of the plate 15). Are formed at a predetermined pitch P.
And according to this structure, since the fitting state which cannot be separated in the said alignment direction is ensured over the full length of the left-right direction, the connection of board | plate materials 15 and 15 can be strengthened, and the integrity of the board wall 11 is achieved. As a result, it is possible to further improve the earthquake resistance of the plate wall 11.

  Desirably, the fiber direction of the plate material 15 made of wood is set along the left-right direction which is the longitudinal direction of the plate material 15. If it does in this way, the compression strength and compression rigidity of fitting convex part 17 and fitting concave part 18 can be raised about the horizontal direction which is the longitudinal direction of board material 15. That is, since the fitting convex portion 17 and the fitting concave portion 18 are mutually compressed in the fiber direction of the plate member 15, the force is transmitted, so that the initial rigidity is increased. As a result, it is possible to reduce the amount of compressive deformation such as crushing and squeezing of the fitting convex portion 17 and the fitting concave portion 18 when a horizontal external force acts on the plate wall 11, and as a result, the left and right plate members 15, 15 adjacent to each other vertically The relative movement in the direction can be reliably regulated.

Since the horizontal proof stress improvement effect of the plate wall 11 by the fitting convex part 17 and the fitting recessed part 18 demonstrated above was confirmed also by experiment, the result etc. are demonstrated below.
4A and 4B are schematic views of the test pieces 11s1 and 11s2 and the test apparatus used in the experiment. FIG. 4A shows the case of the fitting convex portion 17 and the fitting concave portion 18 as an example, and FIG. 4B shows the case of a dowel 121 as a comparative example.

The test piece 11s1 of the embodiment shown in FIG. 4A is roughly equivalent to the one obtained by cutting out the portion of the two-dot chain line in the plate wall 11 of FIG. Moreover, the test piece 11s2 of the comparative example shown in FIG. 4B is also the same size as the above-mentioned example as an external dimension. That is, each of the test pieces 11 s 1 and 11 s 2 has three plate members 15, 15, 15 arranged in the alignment direction orthogonal to the longitudinal direction of the plate member 15.
In the embodiment, one plate material 15, 15 is attached to both sides of the central plate material 15 in the alignment direction by the fitting convex portion 17 and the fitting concave portion 18, respectively. In the example, one plate 15, 15 is attached to both sides of the central plate 15 via dowels 121.

Each of the plate members 15, 15... Has a uniform thickness of 47 mm over the entire surface. Moreover, the dimensions of the fitting convex part 17 and the fitting concave part 18 are the same, and the details are as follows. First, the vertical length L1 as the height of the fitting convex portion 17 is 15 mm, the horizontal length L2b on the base end 17b side of the fitting convex portion 17 is 177 mm, and the horizontal length L2b on the distal end 17s side. The length L2e is 180 mm. In this way, by making the length L2e on the distal end 17s side longer than the length L2b on the proximal end 17b side, as shown in FIG. While the one surface 17e1 is a vertical surface perpendicular to the left-right direction, the other surface 17e2 is inclined from the vertical surface by a predetermined gradient (length in the left-right direction: length in the up-down direction = 6: 15). It has a tapered surface.
On the other hand, in the dimensions of the dowels, the vertical direction × the horizontal direction × the wall thickness direction is 60 mm × 24 mm × 24 mm, respectively.

  On the other hand, the test apparatus has fixed heads 91 and 91 and a movable head 93. The plate members 15 and 15 on both sides of the test piece 11s1 (11s2) are fixed to the fixed heads 91 and 91, and the movable head 93 is fixed to the movable head 93 with the central plate member 15 fixed thereto. By sliding along the longitudinal direction of the plate 15 at a speed of, for example, 2 mm / min, a load in the same direction is applied to the central plate 15 and the load value of the movable head 93 is measured while measuring the load value at that time with the load cell. Measure the slide amount. Then, the measured load value and slide amount are plotted on the same graph as the load value and displacement amount of the load-displacement graph, respectively. In addition, the maximum value of the slide amount was 40 mm, that is, after unloading after sliding to 40 mm.

  5A and 5B show experimental results of Examples and Comparative Examples, respectively. In each figure, the entire graph is shown on the left side, and the initial displacement portion of the graph is enlarged on the right side so that the initial stiffness can be seen. Also, here, the above-described experiment was performed three times for the example and twice for the comparative example, so that FIG. 5A shows three graphs and FIG. 5B shows two graphs. Has been.

  Further, in the same experiment, a coral material is used for the plate material 15 of the plate wall 11 in correspondence with the contents of the above-described embodiment, while a white coral that is harder than the coral is used for the dowel 121 of the comparative example. In addition, the fitting convex part 17 and the fitting recessed part 18 of an Example are naturally the same saddle materials as the board | plate material 15. FIG.

Hereinafter, experimental results will be described with reference to the graphs of FIGS. 5A and 5B.
First, the proof stress of each test piece 11s1, 11s2 was evaluated by the first load peak value in the graph. 5A, the average value of the peak values of the three graphs is 107.7 kN, and in the comparative example of FIG. 5B, the average value of the peak values of the two graphs is 35.kN. 3 kN. From this, it can be seen that the test piece 11s1 of the example shows much higher proof stress than the test piece 11s2 of the comparative example.

  Incidentally, when the graph of the initial stiffness on the right side of FIG. 5A and FIG. 5B is seen, the initial stiffness is significantly higher in the example than in the comparative example. It is assumed that force is transmitted by compression between each other.

  Here, with reference to FIG. 9 and FIG. 1A, an earthquake-resistant repair method using the plate wall 11 of the present embodiment will be described by taking an example of an existing wooden building as an example. This seismic retrofitting is done together when dismantling and repairing existing wooden buildings.

  First, when dismantling the existing column 1 and beam 3 shown in FIG. 9 from the building, the existing plate wall 111 is removed from the column 1 and beam 3. That is, the existing plate materials 115, 115... And dowels 121, 121.

  Next, the plate members 15, 15... Of FIG. Then, the plate members 15 and 15 are sequentially connected by fitting the fitting convex portion 17 and the fitting concave portion 18 and assembled to the plate wall 11. Thereby, a connection structure is changed from the dowel 121 to the fitting convex part 17 and the fitting recessed part 18 integral with the board | plate material 15, and the earthquake resistance is improved.

  Then, before re-assembling the existing pillar 1 and beam 3 after repair, a plurality of mortises 1h, 1h,..., 3h, 3h ... is formed (FIG. 1A). When the columns 1 and the beams 3 are assembled, the tenons 15h, 15h, 15h1, 15h1,... Of the plate wall 11 are fitted into the mortises 1h, 1h,. The plate wall 11 is attached to the column 1 and the beam 3, and the seismic retrofitting work for the plate wall 11 is completed.

By the way, in the above description, only the existing plate wall 111 was replaced with the new plate wall 11 and the existing pillar 1 and beam 3 were used as they were. However, the present invention is not limited to this. For example, an existing wooden building Alternatively, the column 1 and the beam 3 may be newly installed, and the plate wall 11 according to this embodiment may be attached to the added column 1 and beam 3.
Furthermore, it goes without saying that the plate wall 11 of the present embodiment can be applied not to an existing wooden building but to a newly built wooden building.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, The deformation | transformation as shown below is possible in the range which does not deviate from the summary.

In the above-described embodiment, as shown in FIG. 1A, the longitudinal direction of the plate material 15 of the plate wall 11 is aligned in the horizontal direction, but the present invention is not limited to this. For example, as shown in the front view of the plate wall 11 in FIG. 6, the longitudinal direction of the plate material 15 may be aligned in the vertical direction (vertical direction). And also by this structure, the horizontal proof stress of the board wall 11 can be raised by the same reason as the above-mentioned, and it becomes possible to improve the earthquake resistance of a building. That is, when the horizontal external force F0 acts on the plate wall 11, as shown in FIG. 6, the horizontal external force F0 is converted into the vertical shearing force F1 via the internal force of the plate wall 11, so that the shearing force F1 The plate members 15 and 15 move relative to each other in the vertical direction. At this time, the relative movement in the vertical direction is restricted by the fitting convex part 17 by fitting with the fitting concave part 18. The convex part 17 can have the same yield strength improvement effect as the above-mentioned embodiment.
Incidentally, also in this case, the shape of the fitting projection 17 in the front view is parallel to the longitudinal direction of the plate material 15 rather than the length in the direction parallel to the alignment direction of the plate material 15 from the viewpoint of improving the shear load area and the like. It is preferable that the length in the direction is longer. That is, in this case, since the longitudinal direction of the plate member 15 is directed in the vertical direction, the shape of the fitting convex portion 17 is set such that the vertical length is longer than the horizontal length.

  In the above-described embodiment, as shown in FIG. 2, the shape of the fitting convex portion 17 as a whole is a substantially rectangular shape in front view, and the other end surface 17 e 2 in the left-right direction has the tapered surface 17 e 2. The shape of the convex portion 17 is not limited to this. For example, as shown in FIG. 7, the left and right end surfaces 17e3 and 17e4 of the fitting convex portion 17 may be rectangular fitting convex portions 17 formed on a vertical plane orthogonal to the left and right direction. Further, it may be a fitting projection 17 having a triangular shape or a trapezoidal shape when viewed from the front. In these cases, it goes without saying that the fitting concave portion 18 is formed in a concave shape such as the same shape or a similar shape corresponding to the shape of the fitting convex portion 17.

In some cases, as shown in FIG. 8A, the tapered surface of the other end surface 17e2 of the fitting convex portion 17 may be formed as a tapered surface having a gradient opposite to the tapered surface of FIG. Specifically, as shown in FIG. 8A, one end surface 17e1 in the left-right direction of the fitting convex portion 17 is formed on a vertical plane orthogonal to the left-right direction, and the other end surface 17e2 in the left-right direction of the fitting convex portion 17 is fitted. You may form in the taper surface 17e2 so that the length of the left-right direction of the fitting convex part 17 may become large as it goes to the base end 17b from the front-end | tip 17s of the joint convex part 17. As shown in FIG. If it does in this way, the front view shape of the fitting convex part 17 can be made into the shape which the base end 17b side expanded, and it becomes possible to prevent the said fitting convex part 17 from cracking and a chip | tip effectively.
Further, in some cases, in addition to the above-described tapered surface 17e2, as shown in FIG. 8B, the one end surface 17e1 of the fitting convex portion 17 may be a tapered surface having a reverse gradient from the other end surface 17e2. That is, you may form the taper surface of a mutually reverse inclination in the both-ends surface 17e1, 17e2 of the left-right direction of the fitting convex part 17. FIG. In this case, the front-view shape of the fitting convex portion 17 in FIG. 8B is a shape in which the base end 17b side is further expanded, and as a result, cracking and chipping of the fitting convex portion 17 can be more effectively suppressed. It becomes. 8A and 8B, it goes without saying that the fitting concave portion 18 is formed in a concave shape such as the same shape or a similar shape corresponding to the shape of the fitting convex portion 17. .

  In the above-described embodiment, the plate material 15 related to the column 1 and the beam 3 and the plate wall 11 of the building frame is made of wood, but the material is not limited to wood. For example, it may be made of concrete, resin, or metal.

In the above-described embodiment, as shown in FIG. 1A, the shape of the front view of all the fitting convex portions 17, 17... Is the same shape, but is not limited to this. The visual shape may be different.
In addition, if the longitudinal direction of at least one fitting convex portion 17 is oriented in a direction parallel to the longitudinal direction of the plate member 15, the corresponding bending rigidity can be improved. Therefore, at least one fitting convex portion is provided. It suffices if the longitudinal direction of 17 is in a direction parallel to the longitudinal direction of the plate 15.
However, as shown in FIG. 1A, the length L2 of the fitting projection 17 in the longitudinal direction of the plate member 15 (the left-right direction in FIG. 1A) is the alignment direction of the plate member 15 ( Needless to say, it is preferable that the length of the fitting protrusion 17 in the vertical direction in FIG. 1A is equal to or longer than the length L1 because the yield strength of the plate wall 11 can be more reliably increased.

  In the above-described embodiment, the length of the fitting convex portion 17 in the thickness direction (that is, the wall thickness direction) of the plate material 15 is made the same as the thickness of the plate material 15, whereby the fitting convex portion 17 is the plate of the plate material 15. Although it was exposed from the surface in the front direction, it is not limited to this. For example, the length of the fitting convex portion 17 in the thickness direction of the plate material 15 may be smaller than the thickness of the plate material 15, and in that case, the fitting convex portion 17 is embedded in the small end 15 k of the plate material 15. From the front, the fitting convex portion 17 becomes invisible. Incidentally, in this case, from the viewpoint of workability of the fitting operation between the fitting convex portion 17 and the fitting concave portion 18, it is preferable that the left and right end surfaces of the fitting convex portion 17 are formed in parallel to each other. That is, the front shape of the fitting convex portion 17 is preferably a rectangular shape or a parallelogram shape.

  In the above-described embodiment, as shown in FIG. 1A, the plate wall 11 having the tenon 15t integrally formed at both end portions 15e and 15e in the longitudinal direction is illustrated for each plate material 15. Has not been described, so its function and effect will be described here.

  In FIG. 9, the front view of the board wall 111 of a comparative example is shown. As in this comparative example, the plate members 115, 115... Generally associated with the plate wall 111 do not have tenons at both end portions 115e, 115e in the longitudinal direction. Accordingly, even in the pair of left and right columns 1 and 1, no mortise is formed, that is, only the large insertion 1t is formed in a groove shape along the top and bottom. Then, both end portions 115e, 115e in the longitudinal direction of the plate material 115 are inserted into the large case 1t and fixed to the pair of left and right columns 1,1. Similarly, the pair of upper and lower beams 3 and 3 are not formed with a mortise hole, and only the large insertion 3t is formed in a groove shape along the left and right. The upper end surface 115m of the lower end and the lower end surface 115n of the lower end plate member 115 do not have tenons, so that the upper end surface 115m of the upper end plate member 115 and the lower end surface 115n of the lower end plate member 115 become the large inserts 3t and 3t, respectively. It is inserted and fixed to a pair of upper and lower beams 3 and 3.

  In such a configuration, when a horizontal external force F as shown in FIG. 10 is applied, the wooden frame composed of the pillar 1 and the beam 3 is deformed into a parallelogram shape relatively easily as shown by a two-dot chain line in FIG. Resulting in. In other words, since the entire plate cannot transmit shearing force on all sides within the shaft group that has received shearing force, when it receives and resists compressive force in the diagonal direction, compressive force is applied to the corners at both ends of the diagonal. As a result, lateral compression occurs in the direction perpendicular to the fibers on the opposite ends of the plate, and the diagonal length is shortened, so that the wooden frame is easily deformed into a parallelogram. Then, due to the so-called diagonal compression phenomenon, the compression bundle generated on the diagonal of the obtuse inner angles θ1, θ3 of the four inner angles θ1, θ2, θ3, θ4 of the wooden frame shown in FIG. The stress from the compression bundle acts near the intersection of the beam member 3 and the column member 1 due to the influence, and this part is easily damaged.

  On the other hand, in the plate wall 11 of the present embodiment in FIG. 1A, each plate member 15, 15... Has a tenon 15t at each end portion 15e, 15e in the left-right direction, which is the longitudinal direction thereof. Corresponding to the mortises 15t, 15t..., Mortise holes 1h, 1h. Further, a plurality of tenons 15h1, 15h1,... Are intermittently formed on the upper end surface of the upper end plate member 15 and the lower end surface of the lower end plate member 15, and the upper beam 3 and the lower beam are correspondingly formed. A plurality of mortises 3h, 3h,... Are intermittently formed on the bottom surface of each of the three large inserts 3t, 3t.

  Therefore, even when the horizontal external force F shown in FIG. 10 is applied, the stress in the vertical direction can be transmitted to the columns 1 and 1 at both ends 15e and 15e of the plate 15 by fitting the tenon 15t and the tenon 1t. Similarly, by fitting the tenon 15h1 and the tenon 3h, the horizontal stress transmission between the upper end surface of the upper end plate member 15 and the upper beam 3, and the lower end surface of the lower end plate member 15 and the lower beam 3 It is possible to transmit stress in the horizontal direction. As a result, the horizontal and vertical component forces of the compression bundle can be effectively transmitted to the beam member 3 and the column member 1, and the value of the horizontal external force F is larger than that of the frame form shown in FIG. Can be set. As a result, the in-plane shear rigidity and proof stress of the plate wall 11 are further improved.

  That is, since both end portions of each plate member 15 are inserted into the column 1, a vertical shearing force is transmitted, and the upper and lower plate members 15 are fitted to the beam 3 in the same manner as described above. Horizontal shear force is transmitted. For this reason, as in the conventional plate wall 111, if it is just fitted in the grooves 1t and 3t, the force is transmitted to the four-axis shaft with diagonal compression force like a brace, The corner plate 15 is crushed in the direction perpendicular to the fiber and the rigidity and proof strength are not improved. However, this problem can be solved and the rigidity and proof strength can be improved.

  Incidentally, in the above description, the effect of improving the yield strength has been described by taking as an example a case where a plurality of plate materials 15, 15... Are arranged in the vertical direction while aligning the longitudinal direction of the plate material 15 in the horizontal direction (FIG. 1A). This is not a limitation. That is, as shown in FIG. 6, even when a plurality of plate materials 15, 15... Are arranged in the horizontal direction (left-right direction) while aligning the longitudinal direction of the plate material 15 in the vertical direction (vertical direction), the tenon 15h1 Needless to say, the proof stress is improved by the engagement between the mortise and the mortise 1h and the mortise 15h and the mortise 3h.
