[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the present disclosure is not limited to the following embodiments.

[0024] [First embodiment] Fig. 1 is a perspective view showing a plate-like structure for construction according to a first embodiment of the present disclosure. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. The plate-like structure 100 of this embodiment is used as a wall material, particularly as a seismic wall. Furthermore, the plate-like structure 100 of this embodiment alone forms an architectural structure.

[0025] 1, 2 and 6, the plate-like structure 100 comprises a pair of steel frames (also referred to as first steel frames) 1 formed from shaped steel, a pair of wooden intermediate frames 2 joined to the pair of steel frames 1 along the longitudinal direction thereof, and wooden boards 3 joined to the pair of intermediate frames 2. The plate-like structure 100 also comprises intermediate connectors 4 for joining the pair of intermediate frames 2 to the pair of steel frames 1, respectively, and wooden board connectors 5 for joining the wooden boards 3 to the pair of intermediate frames 2, respectively. The plate-like structure 100 further comprises a pair of additional wooden intermediate frames 6.

[0026] The steel frame material 1 of this embodiment is used as a column to form a steel column, and is made of H-shaped steel. As shown in Fig. 2, the steel frame material 1 has a web portion 7 and flange portions 8 that extend perpendicular to each other. Since the steel frame material 1 is an H-shaped steel in this embodiment, a pair of flange portions 8 is provided at both ends of the web portion 7, and the web portion 7 is provided in the middle of the pair of flange portions 8.

[0027] In Figure 2, the direction in which the web portion 7 extends (left-right direction in the figure) is referred to as the direction of the web portion 7, and the direction in which the flange portion 8 extends (up-down direction in the figure) is referred to as the direction of the flange portion 8. Furthermore, with regard to the direction of the web portion 7, the right side of the figure is referred to as one side, and the left side is referred to as the other side. Furthermore, with regard to the direction of the flange portion 8, the upper side of the figure is referred to as the inside, and the lower side is referred to as the outside. In other words, with regard to the direction of the flange portion 8, the direction approaching the width center C (see Figure 1) of the plate-like structure 100 is referred to as the inside, and the direction away from the width center C is referred to as the outside.

[0028] The steel frame 1 extends in a direction perpendicular to the direction of the web portion 7 and the flange portions 8. Therefore, this extending direction is called the longitudinal direction. The steel frame 1, the web portion 7, and the flange portions 8 all extend in the longitudinal direction.

[0029] For ease of understanding, as shown in Figures 1 and 2, the direction of the web portion 7 is referred to as the front-to-rear direction, the direction of the flange portion 8 as the left-to-right direction, and the longitudinal direction as the up-to-down direction. One side of the direction of the web portion 7 is the front side, and the other side is the rear side. With regard to the steel frame 1 on the right side shown in Figure 2, the inside is the upper side, and the outside is the lower side.

[0030] The plate-like structure 100 of this embodiment is configured to be symmetrical from left to right, so the following description will mainly focus on the right side, with supplementary explanations of the left side provided as necessary.

[0031] The steel frame members 1 extend in the vertical direction and are provided in pairs on the left and right. The pair of steel frame members 1 are arranged parallel to each other and spaced apart in the left-right direction. The pair of steel frame members 1 are parallel to each other. The pair of steel frame members 1 are arranged so that the inner surfaces 9 of their respective web portions 7 face each other and so that each pair of flange portions 8 (front and rear) protrudes inward from the web portion 7. However, since the steel frame members in this embodiment are H-shaped steel, the pair of flange portions 8 also protrude outward from the web portion 7.

[0032] The steel frame 1 has a base plate 10 welded to its bottom surface. As is well known, the base plate 10 is a part that is fixed to anchor bolts (not shown) that protrude from a concrete foundation (not shown). The base plate 10 is rectangular and has anchor bolt insertion holes 11 at its four corners. Anchor bolts are inserted into the anchor bolt insertion holes 11, and nuts (not shown) are tightened onto the anchor bolts. This fixes the base plate 10 onto the concrete foundation, and the steel frame 1 is fixed in an upright position on the concrete foundation.

[0033] The intermediate members 2 extend vertically over almost the entire length of the steel frame 1, and are provided in pairs on the left and right. Fig. 2 shows the right-hand intermediate member 2, and Fig. 3 shows the left-hand intermediate member 2. These intermediate members 2 have a symmetrical configuration, so the following explanation will focus on the right-hand intermediate member with reference to Fig. 2.

[0034] The intermediate material 2 abuts or comes into surface contact with the inner surface 9 of the web portion 7, and has a protruding portion 12 that protrudes inward (to the left) from the flange portions 8. The intermediate material 2 is disposed between the front and rear flange portions 8, inside the web portion 7. The intermediate material 2 is disposed between the front and rear flange portions 8 in a fitted state, with a gap between them and the flange portions 8.

[0035] As shown in FIG. 2, the intermediate member 2 is made from a wooden block lumber having a quadrangular (approximately square) cross section, and has a quadrangular basic cross-sectional shape. In this embodiment, a corner of the inner front part of the intermediate member 2, in other words, almost the entire front part of the protruding portion 12, is cut out in a quadrangular shape to form a step portion 13. In the cross-sectional view shown in FIG. 2, the step portion 13 is defined by a step side surface 14 extending in the front-rear direction and a step front surface 15 extending in the left-right direction. The step side surface 14 is located inside the front flange portion 8. The step front surface 15 is located rearward of the front surface 16 of the intermediate member 2.

[0036] The additional intermediate members 6 also extend vertically over almost the entire length of the steel frame 1, and are provided in pairs on the left and right. The additional intermediate members 6 have the same length as the intermediate members 2. These additional intermediate members 6 have a symmetrical configuration, so the following description will focus on the right-hand member with reference to Figure 2.

[0037] The additional intermediate material 6 abuts against the outer surface 17 of the web portion 7 and has a protruding portion 18 that protrudes outward (to the right) from the flange portion 8. The additional intermediate material 6 is disposed between the front and rear flange portions 8, outside the web portion 7. The additional intermediate material 6 is disposed between the front and rear flange portions 8 in a fitted state, with a gap between them and the flange portions 8.

[0038] As shown in Figure 2, the additional intermediate member 6 is made from a wooden block lumber with a quadrangular (approximately square) cross section. The additional intermediate member 6 does not have a step portion 13 like the intermediate member 2. Preferably, the additional intermediate member 6 is made from the same wooden block lumber as the intermediate member 2. This allows for the use of common materials and reduces manufacturing costs.

[0039] The intermediate connector 4 is formed in an axial shape and extends in the left-right direction to connect the web portion 7 and the intermediate member 2. In this embodiment, the intermediate connector 4 connects the intermediate member 2 and the additional intermediate member 6 to the web portion 7.

[0040] In this embodiment, the intermediate connector 4 is formed by a headless bolt, i.e., a cut bolt. Through holes 2A, 6A, and 7A are formed in the intermediate member 2, the additional intermediate member 6, and the web portion 7 in the left-right direction, and the intermediate connector 4 is inserted through these through holes 2A, 6A, and 7A. Nuts 20 are fastened to both ends of the intermediate connector 4 via washers 19, thereby fastening the intermediate member 2, the additional intermediate member 6, and the web portion 7 together. Enlarged diameter portions 21 are provided at the inner end of the through hole 2A in the intermediate member 2 and the outer end of the through hole 6A in the additional intermediate member 6 to accommodate the mounting portions of the washers 19 and nuts 20. This prevents the intermediate connector 4, nuts 20, and washers 19 from protruding from the inner surface 22 of the intermediate member 2 and the outer surface 23 of the additional intermediate member 6.

[0041] As shown in FIG. 1, a plurality (seven) of intermediate connectors 4 and the resulting joints are provided at equal intervals in the longitudinal direction (vertical direction) of the steel frame 1.

[0042] The wooden board 3 functions as a substantial wall material and has a vertically elongated rectangular shape when viewed from the front. The wooden board 3 has a height equal to the length of the intermediate material 2, a predetermined left-right width, and a predetermined front-to-rear thickness. The wooden board 3 of this embodiment is formed from the well-known CLT, but the material is not limited to this. The wooden board 3 is overlapped from the front onto the protruding portion 12. The left-to-right width of the wooden board 3 is slightly smaller than the internal dimension between the front flange portions 8 of the pair of steel frame members 1. Because the wooden board 3 has a symmetrical configuration, the following description will focus on the right side with reference to Figure 2.

[0043] At the outer (right) end of the wooden board 3, a square notch is cut out at the rear corner to form a step 24. In a cross-sectional view as shown in Figure 2, the step 24 is defined by a step side surface 25 extending in the front-to-rear direction and a step rear surface 26 extending in the left-to-right direction.

[0044] In this manner, in this embodiment, steps 13, 24 are formed on both the protruding portion 12 of the intermediate material 2 and the wooden board 3. The protruding portion 12 and the wooden board 3 are fitted together (spigot-fitted) at these steps 13, 24. This allows the relative position of the wooden board 3 in the front-to-rear direction to be further rearward with respect to the intermediate material 2 compared to when the steps 13, 24 are not provided. The wooden board 3 in this embodiment is positioned so as not to protrude from the steel frame material 1 in the front-to-rear direction (particularly to the front).

[0045] More specifically, the front surface 27 of the wooden board 3 and the front surface 16 of the intermediate member 2 are arranged flush (on the same plane). The entire wooden board 3 is positioned within the range of the inside dimension L1 of the front and rear flange portions 8, and is positioned so as not to protrude in the front-to-rear direction beyond the range of the inside dimension L1. The front-to-rear thickness L2 of the wooden board 3 is smaller than the front-to-rear width L3 of the intermediate member 2. Correspondingly, the front-to-rear width L4 of the step portion 24 of the wooden board 3 is smaller than the front-to-rear width L5 of the step portion 13 of the intermediate member 2.

[0046] Here, as a modified example, it is conceivable to not provide the step portion 24 on the wooden board 3, but instead increase the front-to-back width L5 of the step portion 13 of the intermediate material 2 (changing L5 to L5+L4), so that the front surface 27 of the wooden board 3 and the front surface 16 of the intermediate material 2 are flush with each other. However, this would require a larger cutout in the intermediate material 2, which could reduce the strength of the intermediate material 2.

[0047] In the present embodiment, steps 13, 24 are provided on both the intermediate material 2 and the wooden board 3, so the necessary strength of the intermediate material 2 can be ensured without excessively cutting out the intermediate material 2. In addition, because the amount of cutting out of the wooden board 3 is small, the strength of the wooden board 3 can be sufficiently ensured.

[0048] The wooden board connector 5 is formed in a shaft shape and extends in the front-rear direction to connect the wooden board 3 and the protruding portion 12. In this embodiment, the wooden board connector 5 is formed by a well-known drift pin.

[0049] In the intermediate material 2, a portion (uncut portion) 28 of the protruding portion 12 adjacent to the rear side of the step portion 13 and not cut out is formed, and in the wooden board 3, a portion (uncut portion) 29 of the wooden board 3 adjacent to the front side of the step portion 24 and not cut out is formed, with press-fit holes 28A, 29A extending in the front-to-rear direction to allow the wooden board connector 5 to be press-fitted. The press-fit hole 29A in the uncut portion 29 of the wooden board 3 is a through hole. In contrast, the press-fit hole 28A in the uncut portion 28 of the protruding portion 12 is a bottomed hole with an open front end and a closed rear end. The wooden board connectors 5 are press-fitted from the front side into the press-fit holes 29A on the front side and the press-fit holes 28A on the rear side in order, thereby fixing the wooden board 3 to the intermediate material 2. The wooden board connectors 5 are press-fitted to a depth sufficient to prevent them from protruding from the press-fit holes 29A.

[0050] As shown in Figure 1, a plurality of wooden board connectors 5 and the resulting joints are provided at equal intervals in the longitudinal direction (vertical direction) of the steel frame 1. There are more wooden board connectors 5 than intermediate connectors 4, and they are provided at a height position that does not interfere with the intermediate connectors 4.

[0051] When the wooden board 3 is joined to the intermediate material 2, the upper end surface 30 of the wooden board 3 is positioned flush with the upper end surface 31 of the intermediate material 2, as shown in Fig. 6. Also, the lower end surface 32 of the wooden board 3 is positioned flush with the lower end surface 33 of the intermediate material 2, as shown in Fig. 11.

[0052] As shown in Fig. 1, in this embodiment, both ends of another steel frame (referred to as second steel frame) 34 extending in the left-right direction are joined to the upper ends of the left and right steel frames 1. This second steel frame 34 functions as a beam connecting the upper ends of the steel frames 1 acting as columns. This pair of steel frames 1 and second steel frame 34 form a gate-shaped frame, and wooden boards 3 are attached to the pair of steel frames 1 in this frame via intermediate members 2. However, the wooden boards 3 are not attached to the second steel frame 34.

[0053] Figure 13 shows the configuration of the mounting portion of the second steel frame 34. Although Figure 13 shows the configuration of the second embodiment described later, the configuration of the mounting portion of the second steel frame 34 is the same as in the first embodiment, so for convenience, the description will be made using Figure 13. The configuration of this mounting portion is also symmetrical.

[0054] The second steel frame 34 is shown by a dashed line and is positioned above the intermediate member 2 and the wooden board 3. The second steel frame 34 is formed from an H-shaped steel. The second steel frame 34 is oriented so that its web portion 7 extends in the vertical direction and its flange portion 8 extends from the web portion 7 in the front-to-rear direction.

[0055] A pair of upper and lower diaphragms 35 are welded to the upper end of the steel frame 1 at the same height as the upper and lower flange portions 8 of the second steel frame 34. A flat bracket 36 perpendicular to the diaphragms 35 is also welded to these diaphragms 35 and the steel frame 1. The web portion 7 of the second steel frame 34 is attached to the bracket 36 in an overlapping manner using multiple (two) bolts 37 and nuts 38 aligned vertically. After attachment, the upper and lower flange portions 8 and the diaphragms 35 are adjacent to or abutting each other.

[0056] In the plate-like structure 100 of this embodiment, the intermediate members 2 and wooden boards 3 function like braces or diagonal braces. Specifically, as shown in FIG. 7 , when an earthquake or other event occurs, the plate-like structure 100 sways, for example, from side to side, causing the left and right steel frame members 1 to tilt left and right, and the portal frame to deform into a parallelogram shape (except a rectangle). However, the intermediate members 2 and wooden boards 3 resist this tilting and deformation, preventing it. When the left and right steel frame members 1 tilt, the intermediate members 2 tend to shift in position relative to the steel frame members 1 in the longitudinal direction or vertical direction (shear direction) a, and the wooden boards 3 tend to shift in position relative to the intermediate members 2 in the longitudinal direction or vertical direction (shear direction) a. However, these positional shifts are suppressed by the connection with the intermediate connectors 4. The shear force in the longitudinal direction a acting between the steel frame members 1, intermediate members 2, and wooden boards 3 acts as an axial force on the steel frame members 1. Therefore, the intermediate member 2 and the wooden board 3 function like a brace, suppressing tilting of the steel frame 1 and, in turn, shaking and vibration of the plate-like structure 100. In this way, the plate-like structure 100 of this embodiment can function as an excellent earthquake-resistant wall.

[0057] When an earthquake or the like occurs and the plate-like structure 100 shakes, the intermediate members 2 and the wooden boards 3 tend to shift in position in the longitudinal direction (shear direction) a of the steel frame 1. Therefore, preventing this positional shift leads to preventing the plate-like structure 100 from shaking.

[0058] 1, the plate-like structure 100 of this embodiment includes, in addition to the intermediate connector 4, a restricting member 39 that restricts the relative longitudinal movement of the intermediate material 2 with respect to the steel frame material 1. The restricting member 39 abuts against the longitudinal end face of the intermediate material 2.

[0059] 8 and 9 show a first example of the restricting member 39. The restricting member 39 of this first example includes a restricting bracket 40 attached to the inner surface 9 of the web portion 7 of the steel frame 1 and abutting against the upper end surface 31 of the intermediate member 2. The restricting bracket 40 also abuts against the longitudinal end surface of the wooden board 3, specifically the upper end surface 30, and is designed to restrict the longitudinal movement of the wooden board 3 relative to the steel frame 1 and the intermediate member 2.

[0060] 1 and 10 , the restricting member 39 is also used to restrict the longitudinal movement of the additional intermediate member 6 relative to the steel frame material 1. Specifically, the restricting bracket 40 is also attached to the outer surface 17 of the web portion 7 of the steel frame material 1, and is also abutted against the upper end surface 46 of the additional intermediate member 6. Hereinafter, the restricting bracket 40 attached to the inner surface 9 of the web portion 7 will be referred to as the inner restricting bracket 40, and the restricting bracket 40 attached to the outer surface 17 of the web portion 7 will be referred to as the outer restricting bracket 40.

[0061] The regulating bracket 40 is formed from a metal plate and is generally L-shaped overall. The regulating bracket 40 integrally includes a web mounting portion 41 that is attached to and overlaps the inner surface 9 or the outer surface 17 of the web portion 7, an end surface abutting portion 42 that abuts against the upper end surface 31 of the intermediate member 2 or the upper end surface 46 of the additional intermediate member 6, and a pair of reinforcing plates 43 joined to the web mounting portion 41 and the end surface abutting portion 42. The web mounting portion 41 and the end surface abutting portion 42 are formed by bending a single metal plate at a right angle. The pair of reinforcing plates 43 are joined by welding, spanning the web mounting portion 41 and the end surface abutting portion 42 diagonally.

[0062] The positions of the inner and outer regulating brackets 40 in the longitudinal direction (vertical direction) of the web portion 7 are adjustable. Specifically, the web mounting portion 41 is provided with a plurality (four) of elongated holes 44 extending in the vertical direction. The web portion 7 is also provided with the same number (four) of circular holes (not shown) corresponding to the elongated holes 44. A bolt 45 is inserted from the inside through the elongated hole 44 of the inner regulating bracket 40, the circular hole, and the elongated hole 44 of the outer regulating bracket 40, and a nut 45A is tightened onto the male thread portion of the bolt 45 protruding from the outer regulating bracket 40. As a result, the inner and outer regulating brackets 40 are tightened together and fixed to the web portion 7. The height positions of the inner and outer regulating brackets 40 can be adjusted by loosening the nut 45A.

[0063] The inner and outer restraining brackets 40 are fitted between the front and rear flange portions 8 of the steel frame 1. The inner restraining bracket 40 is fixed to the web portion 7 with bolts 45 and nuts 45A at a height position such that it abuts against the upper end surface 31 of the intermediate member 2 and the upper end surface 30 of the wooden board 3. Therefore, the inner restraining bracket 40 restricts any positional deviation in the height direction (specifically, the upward direction) of the intermediate member 2 and the wooden board 3 relative to the steel frame 1. This makes it possible to prevent the plate-like structure 100 from shaking. In particular, the inner restraining bracket 40 abuts against the uncut portion 28 of the protrusion 12 and the uncut portion 29 of the wooden board 3.

[0064] Furthermore, the outer restraining bracket 40 is attached to the outer surface 17 of the web portion 7 of the steel frame 1 and abuts against the upper end surface 46 of the additional intermediate member 6. As a result, the outer restraining bracket 40 also restrains positional deviation in the height direction (specifically, the upward direction) of the additional intermediate member 6 relative to the steel frame 1, further preventing shaking of the plate-like structure 100.

[0065] The restricting member 39 of this first example includes a restricting bracket 40, and a bolt 45 and a nut 45A that attach the restricting bracket 40 to the web portion 7.

[0066] 11 shows a second example of the restricting member 39. The restricting member 39 of this second example includes a fixing plate 47 fixed to the web portion 7 of the steel frame 1 by welding, a restricting plate 48 that abuts against an end face of the intermediate material 2, specifically the lower end face 33, and a pressing bolt 49 that is screwed through the fixing plate 47 and presses the restricting plate 48 against the lower end face 33 of the intermediate material. The restricting plate 48 of this embodiment also abuts against the longitudinal end face of the wooden board 3, specifically the lower end face 32, and is configured to also restrict the longitudinal movement of the wooden board 3 relative to the steel frame 1 and the intermediate material 2.

[0067] The fixing plate 47 is formed from a metal plate that is square in plan view, is placed horizontally, and is welded to the inner surface 9 of the web portion 7 of the steel frame material 1 and to the front and rear flange portions 8 at a position below and spaced a predetermined distance from the intermediate material 2 and the wooden board 3. The fixing plate 47 is provided with a plurality of (two) female screw holes 50 that pass through it and into which a plurality of (two) pressing bolts 49 are screwed.

[0068] 12 is a perspective view of the restricting plate 48 as seen from the bottom side. The restricting plate 48 is also formed from a metal plate that is rectangular in plan view and is arranged horizontally. The bottom surface of the restricting plate 48 is provided with multiple (two) recesses 51 into which the tips of the pressing bolts 49 are inserted and positioned. The restricting plate 48 is fitted into the space surrounded by the inner surface 9 of the web portion 7 of the steel frame 1 and the front and rear flange portions 8.

[0069] The fixing plate 47 and the restricting plate 48 protrude inward from the front and rear flange portions 8 of the steel frame 1. The restricting plate 48 abuts against the uncut portion 28 of the protruding portion 12 and the uncut portion 29 of the wooden board 3, similar to the restricting bracket 40 of the first example.

[0070] As a result, the positional deviation of the intermediate material 2 and the wooden board 3 in the height direction (specifically, the downward direction) relative to the steel frame material 1 is restricted by the restricting plate 48, and shaking of the plate-like structure 100 can be prevented.

[0071] The height position of the regulating plate 48 can be adjusted by tightening or loosening the pressing bolt 49. The effect of this will be explained later.

[0072] By tightening the pressing bolt 49, the position of the restricting plate 48 rises and the restricting plate 48 is pressed against the lower end surface 33 of the intermediate material and the lower end surface 32 of the wooden board 3. A lock nut may be added to prevent the pressing bolt 49 from loosening after tightening.

[0073] As shown in Fig. 1, the restricting member 39 of this second example is also used to restrict the longitudinal movement of the additional intermediate member 6 relative to the steel frame material 1. Specifically, below the additional intermediate member 6, a fixing plate 47 is attached to the outer surface 17 of the web portion 7 of the steel frame material 1. A restricting plate 48 is then abutted against the lower end surface of the additional intermediate member 6, and a pressing bolt 49 presses the restricting plate 48 against the lower end surface of the additional intermediate member 6. In this way, the restricting plate 48 also restricts positional deviation in the height direction (specifically, the downward direction) of the additional intermediate member 6 relative to the steel frame material 1, making it possible to further prevent shaking of the plate-like structure 100.

[0074] 13 and 14 show a third example of the restricting member 39. The restricting member 39 of this third example includes a diaphragm (specifically, a lower diaphragm) 35 welded to the steel frame 1 across a gap from the upper end surface 31 of the intermediate member 2, a mortar frame 52 inserted into the gap and abutting against the upper end surface 31 of the intermediate member 2, and mortar 53 filled into the mortar frame 52 so as to fill the gap. The mortar frame 52 of this embodiment also abuts against the upper end surface 30 of the wooden board 3, and is designed to restrict the relative longitudinal movement of the wooden board 3 with respect to the steel frame 1 and the intermediate member 2.

[0075] An area (referred to as the inner flange area) surrounded by the web 7 and the front and rear flanges 8 is formed inside the web 7 of the steel frame 1. The mortar frame 52 is partially inserted and fitted into the inner flange area from the inside to the outside. The inner flange area is rectangular in plan view, and the mortar frame 52 is rectangular in plan view that is longer in the left-right direction than the inner flange area.

[0076] 14, the mortar frame 52 is formed of a metal plate. The mortar frame 52 is divided into an inserted portion 52A that is inserted into the inner flange region and an uninserted portion 52B that is not inserted into the inner flange region. The dashed-dotted line a is the boundary line that separates the inserted portion 52A from the uninserted portion 52B.

[0077] The mortar frame 52 has a bottom plate portion 54 that abuts against the upper end surfaces 31, 30 of the intermediate material 2 and the wooden board 3. An uninserted portion 52B of this bottom plate portion 54 abuts against both the protruding portion 12 of the intermediate material 2 and the wooden board 3. The bottom plate portion 54 prevents the mortar 53 from coming into direct contact with the intermediate material 2 and the wooden board 3, thereby protecting the intermediate material 2 and the wooden board 3.

[0078] In the uninserted portion 52B of the mortar frame 52, a frame plate portion 55 having a U-shape in plan view is provided along the peripheral edge of the bottom plate portion 54 to prevent the mortar 53 filled in the mortar frame 52 from leaking out.

[0079] For the insertion portion 52A, the web portion 7 and the front and rear flange portions 8 of the steel frame 1 function as a frame plate to prevent the outflow of the mortar 53, so a frame plate portion 55 is not provided. The frame plate portion 55 and the front and rear flange portions 8 are adjacent to each other, and their inner surfaces are arranged flush with each other.

[0080] As shown in Figure 13, the bottom plate portion 54 of the mortar frame 52 and the diaphragm 35 have the same shape in a plan view, and when the mortar frame 52 is inserted into the gap, the gap is closed by the frame plate portion 55. Mortar 53 is injected through an injection port 56 formed in the diaphragm 35. Air is discharged from the small gap between the steel frame 1 and the diaphragm 35 when the mortar is injected, and water vapor is discharged when the mortar dries.

[0081] In this way, the mortar frame 52 and the mortar 53 are integrally attached to the steel frame 1 and the diaphragm 35, filling the gaps between the intermediate member 2 and the wooden board 3 and the diaphragm 35. The dashed line a in FIG.

[0082] In this third example, the mortar frame 52 is brought into contact with the uncut portion 28 of the protruding portion 12 of the intermediate material 2 and the uncut portion 29 of the wooden board 3 .

[0083] The mortar 53 and mortar frame 52 regulate the positional deviation of the intermediate material 2 and wooden board 3 in the height direction (specifically, the upward direction) relative to the steel frame 1, thereby preventing the plate-like structure 100 from shaking.

[0084] Although the restricting member 39 in this third example is not provided for the additional intermediate member 6, it may of course be provided.

[0085] Next, a method for assembling the plate-like structure 100 of this embodiment will be described. Here, examples using first and second examples of the restricting member 39 will be shown.

[0086] First, a pair of steel frame members 1 forming pillars is placed on a concrete foundation (not shown) as shown in Fig. 3. At this time, anchor bolts (not shown) are inserted into the anchor bolt insertion holes 11 of the base plate 10, and nuts (not shown) are tightened onto the anchor bolts to fix the pair of steel frame members 1 onto the concrete foundation.

[0087] Next, a second steel frame 34 forming a beam is attached to the pair of steel frames 1 using bolts 37 and nuts 38. This forms a gate-shaped frame.

[0088] Next, the intermediate member 2 and the additional intermediate member 6 are attached to the pair of steel frames 1 using intermediate connectors 4, washers 19, and nuts 20, respectively. As a result, the intermediate member 2 and the additional intermediate member 6 are attached to the steel frame 1 along its longitudinal direction, and the steel frame 1 is reinforced.

[0089] Next, as shown in FIG. 4, the wooden board 3 is overlapped on the pair of intermediate members 2 from the front and fitted together.

[0090] Next, as shown in Fig. 5, wooden boards 3 are attached to the pair of intermediate members 2 using wooden board connectors 5. This joins the pair of steel frames 1, the pair of intermediate members 2, the pair of additional intermediate members 6, and the wooden boards 3 together to form a strong earthquake-resistant wall. Fig. 7 is a front view corresponding to Fig. 5.

[0091] 1, the first example of the restricting member 39 (including the restricting bracket 40, etc.) is attached to the upper side. The second example of the restricting member 39 (including the restricting plate 48, etc.) is attached to the lower side. This completes the plate-like structure 100, further increasing its strength.

[0092] In addition, the fixing plate 47 of the restricting member 39 in the second example is welded in advance to the steel frame 1. The order of attaching the steel frame 1 to the intermediate member 2 and the additional intermediate member 6 may be reversed, with the intermediate member 2 and the additional intermediate member 6 being attached to the steel frame 1 first, and then the steel frame 1 being attached to the concrete foundation.

[0093] Next, the effects of this embodiment will be described.

[0094] In this embodiment, the intermediate member 2 and the additional intermediate member 6 are attached in advance to the steel frame member 1 by intermediate connectors 4 extending in the left-right direction. Then, the wooden board 3 is placed on the intermediate member 2 from the front, and the wooden board 3 is attached to the intermediate member 2 by wooden board connectors 5 extending in the front-rear direction.

[0095] Therefore, the configuration of the plate-like structure 100 is very simple. Also, the work of attaching the wooden boards 3 can be performed from the front side of the wooden boards 3, making installation very easy. In particular, the work of attaching the wooden boards 3 is very easy because it is only necessary to drive and press-fit the wooden board connectors 5, which are made of drift pins, into the press-fit holes 29A of the wooden boards 3 and the press-fit holes 28A of the intermediate material 2 from the front.

[0096] Meanwhile, the intermediate member 2 and the additional intermediate member 6 sandwich the web portion 7 of the steel frame 1 and can be firmly joined to the web portion 7 by the intermediate connector 4. This allows the web portion 7 to be significantly reinforced, and the bending deformation of the steel frame 1 due to horizontal force and the buckling deformation due to axial force can be reliably suppressed.

[0097] As described above, the intermediate material 2 and the wooden board 3 function like a brace, so that the shaking and vibration of the plate-like structure 100 can be reliably suppressed when an earthquake occurs.

[0098] In addition, the brace functional parts attached to the steel frame 1 are divided into intermediate members 2 and wooden boards 3, which can be attached from different directions (towards the flange portion and the web portion), improving workability.

[0099] In addition, the metal steel frame 1 is combined with the wooden intermediate material 2, the additional intermediate material 6, and the wooden board 3, giving the plate-like structure 100 a soft overall impression, which is also effective in terms of design.

[0100] In this embodiment, an additional intermediate member 6 is provided in addition to the intermediate member 2, and the web portion 7 of the steel frame 1 is sandwiched between the intermediate member 2 and the additional intermediate member 6, and they are fastened together by a common intermediate connector 4. This increases the strength of the web portion 7 and makes it easy to attach the intermediate member 2 and the additional intermediate member 6.

[0101] In this embodiment, steps 13, 24 are formed on the protruding portion 12 of the intermediate material 2 and the wooden board 3, and the protruding portion 12 and the wooden board 3 are fitted together at the steps 13, 24. This makes it easy to position the wooden board 3 relative to the intermediate material 2, and makes it easy to attach the wooden board 3. It is also advantageous to position the wooden board 3 so that it does not protrude in the front-to-rear direction from the steel frame material 1, improving earthquake resistance performance.

[0102] In other words, if the wooden board 3 protrudes in the front-to-back direction from the steel frame 1, the left-to-right force applied from one steel frame 1 during an earthquake will escape in the front-to-back direction, making it difficult to transmit that force to the other steel frame 1.

[0103] In this embodiment, the wooden board 3 is positioned so that it does not protrude in the front-to-rear direction (particularly the front side) from the steel frame 1. The entire wooden board 3 is positioned within the range of the inside dimension L1 of the front and rear flange portions 8, and is positioned so that it does not protrude in the front-to-rear direction beyond the range of the inside dimension L1. Therefore, in the event of an earthquake, the left-to-right force applied from one steel frame 1 can be efficiently transmitted to the other steel frame 1, resulting in high earthquake resistance performance.

[0104] In this embodiment, the steps 13, 24 are provided on both the protrusion 12 and the wooden board 3, so that the thickness of the uncut portions 28, 29 in the front-rear direction can be ensured sufficiently, and the strength of both can be ensured sufficiently.

[0105] In this embodiment, a restricting member 39 is provided that abuts against the longitudinal end face of the intermediate material 2 to restrict the relative longitudinal movement of the intermediate material 2 with respect to the steel frame material 1, thereby preventing the intermediate material 2 from shifting in position in the longitudinal direction of the steel frame material 1 when an earthquake occurs, thereby improving earthquake resistance performance.

[0106] In this embodiment, the restricting members 39 also abut on the longitudinal end faces of the wooden boards 3. This prevents the wooden boards 3 from shifting in position in the longitudinal direction relative to the intermediate members 2 and the steel frame members 1 in the event of an earthquake, further improving earthquake resistance.

[0107] In this embodiment, the restricting member 39 is also provided for the additional intermediate member 6, so that the additional intermediate member 6 can be prevented from shifting in position when an earthquake occurs, and earthquake resistance can be further improved.

[0108] Generally, wood tends to shrink over time. In the case of the first example of the restricting member 39 shown in Fig. 8, the positions of the upper end surface 31 of the intermediate material 2 and the upper end surface 30 of the wooden board 3 may drop over time, creating a gap between the restricting bracket 40 and the upper end surfaces 31 and 30.

[0109] However, in this embodiment, the height position of the restriction bracket 40 is adjustable, so it is possible to prevent such gaps from occurring. For example, if the positions of the upper end faces 31, 30 drop over time, creating a gap, the bolts 45 can be loosened to lower the position of the restriction bracket 40, and then the restriction bracket 40 can be brought into contact with the upper end faces 31, 30 again, and then the bolts 45 can be tightened. This allows the earthquake-resistant effect of the restriction member 39 to be maintained.

[0110] The same is true for the second example of the restricting member 39 shown in Figure 11, since the height position of the restricting plate 48 is adjustable. For example, if the positions of the bottom end surface 33 of the intermediate material 2 and the bottom end surface 32 of the wooden board 3 rise over time, creating a gap, the pressing bolt 49 can be tightened to raise the position of the restricting plate 48 so that it once again abuts against the bottom end surfaces 33, 32. This allows the earthquake-resistant effect of the restricting member 39 to be maintained.

[0111] 13, the height of the mortar frame 52 cannot be adjusted. Therefore, if gaps occur between the upper end surface 31 of the intermediate material 2 and the upper end surface 30 of the wooden board 3 and the mortar frame 52, measures such as inserting additional boards to fill these gaps can be considered.

[0112] Although the restricting member 39 of the first example has an orthodox structure, it is somewhat disadvantageous in that it is relatively large in height. In contrast, the restricting members 39 of the second and third examples can be made smaller in height than the restricting member 39 of the first example. Therefore, when the restricting members 39 of the second and third examples are used on the upper end surfaces 31 and 30, the gap between the intermediate member 2 and the wooden board 3 and the second steel frame member 34 serving as a beam can be reduced. See Figures 1 and 13 for a comparison. The restricting member 39 of the third example is characterized in that it uses a diaphragm 35, which is intended for a separate purpose, such as for attaching the second steel frame member 34, as one of its components.

[0113] There is a clearance required for insertion between the through holes 2A, 6A, 7A of the intermediate material 2, additional intermediate material 6, and web portion 7 and the intermediate connectors 4 that are inserted through them. Therefore, there is a possibility that the intermediate material 2 and additional intermediate material 6 may shift in position in the longitudinal direction relative to the steel frame material 1 due to shaking, aging, manufacturing errors, construction errors, etc. The restricting member 39 is also effective in preventing such positional shifts.

[0114] [Second embodiment] Next, a second embodiment of the present disclosure will be described. Note that a description of the same parts as in the first embodiment will be omitted, and the following description will focus on the differences.

[0115] 15 shows a plate-like structure 200 according to the second embodiment. This plate-like structure 200 is used as a ceiling material, particularly an earthquake-resistant ceiling, and is joined to the upper end of the front surface of the plate-like structure 100 of the first embodiment.

[0116] The plate-like structure 200 of this embodiment is basically configured in the same way as the plate-like structure 100 of the first embodiment. However, the restricting member 39 is not provided. The plate-like structure 200 of this embodiment comprises a pair of steel members (also referred to as third steel members) 201, a pair of intermediate members 202, a wooden board 203, an intermediate connector 204, and a wooden board connector 205 (see FIG. 18). The plate-like structure 200 further comprises a pair of additional intermediate members 206. The plate-like structure 200 is also configured symmetrically.

[0117] The third steel frame 201 is used as a beam to form a steel beam. The third steel frame 201 is joined by welding to the upper front end of the steel frame 1 at a height equal to that of the second steel frame 34 of the plate-like structure 100. The third steel frame 201, and therefore the plate-like structure 200, extends diagonally upward and forward from the steel frame 1. The longitudinal length of this plate-like structure 200 is relatively short in the illustrated example, but may be formed to a longer length.

[0118] These plate-like structures 100 and 200 constitute an architectural structure 300. A method for assembling the architectural structure 300 will be described below.

[0119] First, as shown in Figure 16, a pair of steel frames 1 and a second steel frame 34 are assembled as in the first embodiment, and then the base end surface or rear end surface of a pair of third steel frames 201 is welded to the upper front end portions of the pair of steel frames 1.

[0120] Next, as shown in Figure 17, the intermediate member 2 and additional intermediate member 6 of the plate-like structure 100 are attached to a pair of steel frames 1, respectively, and the intermediate member 202 and additional intermediate member 206 of the plate-like structure 200 are attached to a pair of third steel frames 201, respectively.

[0121] 18, wooden boards 3 are attached to the pair of intermediate members 2 of the plate-like structure 100, and wooden boards 203 are attached to the pair of intermediate members 202 of the plate-like structure 200. At this time, the wooden boards 203 are attached to the pair of intermediate members 202 from below.

[0122] Finally, as shown in FIG. 15, the restricting members 39 of the first and second examples are attached to the plate-like structure 100, and the architectural structure 300 is completed.

[0123] The plate-like structure 200 has the same configuration as the plate-like structure 100, except for its orientation, and therefore functions as an excellent earthquake-resistant ceiling, and can reliably suppress the shaking and vibration of the architectural structure 300 in the event of an earthquake, etc. Furthermore, like the plate-like structure 100, it is also very easy to install.

[0124] Since the plate-like structure 200 is a ceiling material, it is desirable that it be able to deform more flexibly in the event of an earthquake, etc., compared to the plate-like structure 100, which is a wall material. For this reason, no restricting member is provided on the plate-like structure 200. However, such a member may be provided if necessary.

[0125] These plate-like structures 100, 200 can be used not only as the architectural structure 300 shown in the figure, but also as components of any architectural structure, such as wall materials or ceiling materials. For example, the plate-like structures 100, 200 can be used as wall materials and ceiling materials in a triangular arch-shaped architectural structure installed across a sidewalk for design purposes. In this way, it is possible to grasp an architectural structure in which the architectural plate-like structure according to the present disclosure is used as at least one of a wall material and a ceiling material.

[0126] Although the embodiments of the present disclosure have been described in detail above, various other embodiments and modifications of the present disclosure are possible.

[0127] (1) For example, as shown in Figure 19, the additional intermediate member 6 (or 206) may be omitted. In this case, the intermediate connector 4 connects only the intermediate member 2 to the steel frame 1. Please refer to Figure 2 and Figure 19 by comparing them.

[0128] (2) In the first example of the regulating member 39 shown in FIGS. 8, 9 and 10, the elongated hole 44 of the regulating bracket 40 may be changed to a circular hole, and the circular hole of the web portion 7 may be changed to a elongated hole extending in the height direction.

[0129] Also, instead of using the nuts 45A, female screw holes may be provided in the web portion 7, and the bolts 45 may be fastened into the female screw holes to attach the regulating brackets 40. The inner and outer regulating brackets 40 do not necessarily have to be fastened together, and may be attached separately.

[0130] (3) For example, in the first embodiment, the cross-sectional structures of the steel frame material 1, the intermediate material 2, and the wooden board 3 can be changed.

[0131] FIG. 20 is a plan cross-sectional view showing a number of modified examples in which the cross-sectional structure has been changed. In FIG. 20, (A) is a diagram showing a standard example of the cross-sectional structure of FIG. 2. In a first modified example shown in (B), the steel frame material 1 has been changed to a channel steel with a U-shaped cross section. In a second modified example shown in (C), the steel frame material 1 has been changed to an angle steel with an L-shaped cross section. In a third modified example shown in (D), the steel frame material 1 has been changed to a T-shaped steel with a T-shaped cross section. In a fourth modified example shown in (E), the steel frame material 1 has been changed to a Z-shaped steel with a Z-shaped cross section.

[0132] In the fifth to eighth modified examples shown in (F) to (I), the cross-sectional structures of the intermediate member 2 and the wooden board 3 are modified compared to the standard example. In the fifth modified example shown in (F), the step portion 24 of the wooden board 3 is omitted, and the step portion 13 is provided only in the intermediate member 2. Compared to the standard example, the front-to-rear width L5 of the step portion 13 is increased. In the sixth modified example shown in (G), the step portion 13 of the intermediate member 2 is omitted, and the step portion 24 is provided only in the wooden board 3. This causes the wooden board 3 to protrude forward from the steel frame material 1. In the seventh modified example shown in (H), no step portion is provided in either the intermediate member 2 or the wooden board 3. In this case, the wooden board 3 protrudes further forward from the steel frame material 1. In the eighth modified example shown in (I), step portions 13, 24 are provided in both the intermediate member 2 and the wooden board 3. However, the front surface 27 of the wooden board 3 is positioned flush with the front surface 57 of the steel frame material 1, so that the wooden board 3 does not protrude forward from the steel frame material 1 as much as possible. In this way, the thickness in the front-to-rear direction of the uncut portions 28, 29 in at least one of the intermediate material 2 and the wooden board 3 can be increased compared to the standard example.

[0133] These cross-sectional structures are also applicable to the second embodiment.

[0134] (4) FIG. 21 is a cross-sectional plan view showing a ninth modified example, which is a modified example of the first embodiment.

[0135] In this modification, protruding portions 2B and 6B that protrude further rearward than the rear flange portion 8 are additionally provided to the intermediate member 2 and the additional intermediate member 6 of the first embodiment.

[0136] In the intermediate material 2, the protruding portion 12 that protrudes inward from the flange portion 8 is extended rearward to form the protruding portion 2B. Alternatively, the protruding portion 2B is formed by extending rearward the uncut portion 28 that is adjacent to and directly behind the cut-out step portion 13.

[0137] In the additional intermediate material 6, the protruding portion 18 that protrudes outward from the flange portion 8 is extended rearward to form the protruding portion 6B. The protruding portion 6B of the additional intermediate material 6 is configured to be plane-symmetrical to the protruding portion 2B of the intermediate material 2 with the position of the web portion 7 as the boundary.

[0138] According to this modification, the front-rear thickness of the intermediate member 2 and the additional intermediate member 6 increases by the amount of the added protrusions 2B and 6B, and therefore the rigidity thereof can be increased.

[0139] (5) FIG. 22 is a cross-sectional plan view showing a tenth modified example, which is a modified example of the first embodiment.

[0140] In this modification, a steel frame 1A that functions as a partition or connecting member is additionally provided between the steel frame 1 that forms the left and right columns. An intermediate member 2 and a wooden board 3 are attached to the left and right side surfaces 9A, 17A of the web portion 7 of this steel frame 1A. Therefore, there are multiple wooden boards 3.

[0141] In this case, the configuration of the intermediate material 2 and wooden board 3 on the left side of the web portion 7 is the same as the configuration of the intermediate material 2 and wooden board 3 on the right side of the first embodiment shown in Figure 2. Also, the configuration of the intermediate material 2 and wooden board 3 on the right side of the web portion 7 is the same as the configuration of the intermediate material 2 and wooden board 3 on the left side of the first embodiment.

[0142] In other words, the configuration of the intermediate material 2 and wooden board 3 on the left side of the web portion 7 and the configuration of the intermediate material 2 and wooden board 3 on the right side of the web portion 7 are plane-symmetrical with respect to the web portion 7.

[0143] The illustrated left and right intermediate members 2 are fastened together to the web portion 7. That is, intermediate connectors 4 are inserted into the through holes 2A of the left and right intermediate members 2 and the through holes 7A of the web portion 7. Nuts 20 are fastened to both ends of the intermediate connectors 4 via washers 19, and the left and right intermediate members 2 and the web portion 7 are fastened together and fixed to each other.

[0144] According to this modification, even if the width of the plate-like structure 100 becomes large, the width of each wooden board 3 can be kept small, improving workability. In addition, since multiple wooden boards 3 can be connected by intermediate members 2 and steel frames 1A, the overall rigidity can be increased.

[0145] By increasing the number of such steel frames 1A, intermediate members 2 and wooden boards 3, the left and right width of the plate-like structure 100 can be gradually increased.

[0146] The structure of this modified example can also be applied to the plate-like structure 200 according to the second embodiment. In this case, a steel frame 1A that functions as an intermediate beam or a connecting member is added between third steel frames 201 that form the left and right beams.

[0147] (6) FIG. 23 is a cross-sectional plan view showing an eleventh modified example, which is a modification of the tenth modified example (FIG. 22).

[0148] In this modification, the steel frame 1A described above is replaced with a square steel pipe 1B. The square steel pipe 1B has a through hole 7B penetrating in the left-right direction, and an intermediate connector 4 is inserted into this through hole 7B. This also achieves the same effects as the tenth modification.

[0149] The configurations of the above-described embodiments and variations can be combined in part or in whole unless there is a particular contradiction. The embodiments of the present disclosure are not limited to the above-described embodiments, and all variations, applications, and equivalents encompassed within the spirit of the present disclosure as defined by the claims are included in the present disclosure. Therefore, the present disclosure should not be interpreted as being limited, and can be applied to any other technology that falls within the spirit of the present disclosure.
