Description

  The present invention relates to a load-bearing wall panel constituting a load-bearing wall of a building such as a house or an apartment house.

  As this type of load-bearing wall panel conventionally used, for example, a configuration shown in Patent Document 1 or the like below can be cited. That is, in the conventional configuration, a pair of vertical frames, an upper frame material, and a lower frame material are connected in a rectangular shape to form a frame. The face material is overlapped on the frame so as to cover the opening of the frame, and the face material is joined to the frame by driving a drill screw into the face material and the frame over the entire circumference of the frame. The joint by the drill screw secures the shear performance of the load-bearing wall panel. The higher the shear performance of a load-bearing wall panel, the higher the seismic performance of a building using the load-bearing wall panel.

JP 2017-002513 A

  In the above-described conventional load-bearing wall panel, since the face material is joined to the frame by driving a drill screw into the face material and the frame over the entire circumference of the frame, the load-bearing wall is subjected to, for example, an earthquake or strong wind. When a horizontal force is applied to the panel, the face material and the frame are going to be integrally deformed. When the horizontal force input to the load-bearing wall panel exceeds a predetermined magnitude, breakage occurs, for example, in which a drill screw is cut into a face material, and the strength of the load-bearing wall panel is reduced.

  In general, in order to make the bearing wall panels less likely to break, the number of bearing wall panels used in the building is increased to disperse the horizontal force acting on each bearing wall panel. However, simply increasing the number of load-bearing wall panels results in an excessive acceleration response of the building when a horizontal force acts on the building, resulting in a heavy load on the members supporting the load-bearing wall panels and the load-bearing wall panels themselves. For this reason, it is considered that for the input of the horizontal force, increasing the damping performance of the horizontal force is superior to increasing the rigidity of the building.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a load-bearing wall panel capable of improving the horizontal force damping performance of a building.

  A load-bearing wall panel according to the present invention includes a first vertical frame member, a second vertical frame member, an upper frame member, and a lower frame member connected to each other so as to form a rectangular shape as a whole. A frame body having an opening surrounded by the vertical frame material, the upper frame material, and the lower frame material; and at least one of the first and second vertical frame materials displaceable in the extending direction of the first and second vertical frame materials. A fastened variable frame member, and a face member disposed to close the opening of the frame body and connected to at least one of the first and second vertical frame members via the variable frame member; The horizontal force input to the frame is attenuated by friction caused by relative displacement between the first and second vertical frame members and the variable frame member.

  According to the load-bearing wall panel of the present invention, the horizontal force input to the frame is attenuated by the friction accompanying the relative displacement between the first and second vertical frame members and the variable frame member. Therefore, the horizontal force damping performance of the building can be improved.

  The load-bearing wall panel 1 shown in FIG. 1 is a panel material for forming a load-bearing wall of a building such as a house or an apartment house. Although the load-bearing wall panel 1 of the present embodiment is mainly adapted to be used in a thin-walled lightweight steel building, the load-bearing wall panel of the present invention may be used in other buildings.

  As shown in FIG. 1, the load-bearing wall panel 1 has a rectangular shape having a height direction 1a and a width direction 1b. The load-bearing wall panel 1 is adapted so that the height direction 1a extends in the vertical direction and the width direction 1b extends in the horizontal direction. The load-bearing wall panel 1 has a frame 2, a variable frame member 3, a plurality of fasteners 4 and a face member 5.

  As shown in FIGS. 1 and 2, the frame 2 includes a first vertical frame member 21, a second vertical frame member 22, an upper frame member 23, a lower frame member 24, an intermediate vertical frame member 25, and a plurality of hole-down hardware. 26.

  The first and second vertical frame members 21 and 22 are elongated members that extend in the height direction 1 a of the load-bearing wall panel 1, and are spaced apart from each other in the width direction 1 b of the load-bearing wall panel 1. . The first and second vertical frame members 21 and 22 of the present embodiment are made of lip-shaped channel steel. The lip-shaped channel steel is a section steel having a web, a pair of flanges protruding from both sides of the web, and a pair of lips protruding from the tip of the flange. The first and second vertical frame members 21 and 22 are arranged such that the back surfaces of the webs (the surfaces on the side where the flange is not projected) face each other. The back surface of the web constitutes vertical frame inner surfaces 21a and 22a of the first and second vertical frame members 21 and 22.

  The upper frame member 23 and the lower frame member 24 are elongate members extending in the width direction 1b of the load-bearing wall panel 1, and are arranged apart from each other in the height direction 1a of the load-bearing wall panel 1. As the upper frame member 23 and the lower frame member 24, members shorter than the first and second vertical frame members 21 and 22 are used. The upper frame member 23 and the lower frame member 24 of the present embodiment are made of channel steel. A channel steel is a steel section having a web and a pair of flanges protruding from both sides of the web. The upper frame member 23 and the lower frame member 24 are arranged such that the surfaces of the webs (the surfaces on the side from which the flanges protrude) face each other.

  As shown in FIG. 1, the first vertical frame member 21, the second vertical frame member 22, the upper frame member 23, and the lower frame member 24 are connected to each other so as to form a rectangle as a whole. At the center of the frame 2, an opening 2a is provided which is surrounded by the first vertical frame member 21, the second vertical frame member 22, the upper frame member 23 and the lower frame member 24.

The detailed relationship between the first vertical frame member 21, the second vertical frame member 22, the upper frame member 23, and the lower frame member 24 is as follows.
That is, the upper ends of the first and second vertical frame members 21 and 22 are inserted between the flanges of the upper frame member 23. By attaching the connecting member 6 to the flanges of the first and second vertical frame members 21 and 22 and the flange of the upper frame member 23, the upper ends of the first and second vertical frame members are connected to the upper frame member 23. I have.
Similarly, the lower ends of the first and second vertical frame members 21 and 22 are inserted between the flanges of the lower frame member 24. By connecting the connecting member 6 to the flanges of the first and second vertical frame members 21 and 22 and the flange of the lower frame member 24, the lower ends of the first and second vertical frame members 21 and 22 are attached to the lower frame member 24. Are linked.
As the connecting member 6, it is preferable to use a drill screw from the viewpoint that drilling of a pilot hole can be omitted, but other members such as a normal bolt and nut or a rivet may be used.

  The first and second vertical frame members 21 and 22 are rotatable about a connection point between the upper frame member 23 and the lower frame member 24. By setting the number of connecting members 6 used for each connecting portion to one, the first and second vertical frame members 21 and 22 can be more reliably rotatable. Even if the number of connecting members 6 used in each connecting portion is two or more, by arranging those fastening members in a narrow area, the first and second vertical frame members 21 and 22 can be made rotatable. it can.

  The intermediate vertical frame member 25 is a longitudinal member extending in the height direction 1 a of the load-bearing wall panel 1, and is an intermediate position between the first and second vertical frame members 21 and 22 in the width direction 1 b of the load-bearing wall panel 1. Are located in The intermediate vertical frame member 25 of the present embodiment is made of the same lip-shaped channel steel as the first and second vertical frame members 21 and 22 described above. The upper end of the intermediate vertical frame member 25 is inserted between the flanges of the upper frame member 23 and is connected to the upper frame member 23 by the connecting member 6. Similarly, the lower end of the intermediate vertical frame member 25 is inserted between the flanges of the lower frame member 24 and is connected to the lower frame member 24 by the connecting member 6.

  The plurality of hole-down metal members 26 are metal members fixed to upper and lower portions of the first and second vertical frame members 21 and 22. When the first vertical frame member 21, the second vertical frame member 22, the upper frame member 23, and the lower frame member 24 are connected in a rectangular shape, the hole-down metal member 26 and the upper frame member 23 and the lower frame member 24 The insertion holes 7a are arranged in a straight line. An anchor bolt 7 shown by a two-dot chain line in FIG. 3 is passed through the insertion hole 7a. The anchor bolts 7 can connect the load-bearing wall panel 1 to a foundation, a floor panel of a higher floor or another load-bearing wall panel 1.

  As shown particularly in FIG. 3, the hole-down metal member 26 is disposed so as to have a gap 26 a having a predetermined width between the upper frame member 23 and the web of the lower frame member 24. If the gap 26a is small, the hole-down metal member 26 comes into contact with the upper frame member 23 and the lower frame member 24 when the first and second vertical frame members 21 and 22 are rotated, so that the first and second vertical frames are formed. The rotation of the members 21 and 22 is restricted. The gap 26a has a width that allows the assumed maximum amount of rotation of the first and second vertical frame members 21 and 22. The width of the gap 26a is such that the hole-down metal member 26 does not contact the upper frame member 23 and the lower frame member 24 even when the first and second vertical frame members 21 and 22 are rotated by the assumed maximum amount. be able to. Also, by providing such a gap 26a, it is possible to correct the displacement between the foundation, the floor panel on the upper floor or the other load-bearing wall panel 1 and the load-bearing wall panel 1.

  The variable frame member 3 is displaceable in the extending direction of the first and second vertical frame members 21 and 22 (that is, the height direction 1a of the load-bearing wall panel 1) by the plurality of fasteners 4 so as to be displaceable. These members are fastened to the members 21 and 22.

  Returning to FIG. 1, the face material 5 is a flat member arranged so as to close the opening 2 a of the frame 2. The face material 5 of the present embodiment has a face material main body 51 and a plurality of interpolated face materials 52.

  The face material main body 51 is a flat plate-shaped member having an area larger than the opening 2a, and is arranged so as to cover the opening 2a from the outside of the frame 2. The outer peripheral portion of the face material main body 51 is overlaid on the webs of the first vertical frame material 21, the second vertical frame material 22, the upper frame material 23, and the lower frame material 24. As particularly shown in FIG. 1, the face material main body 51 is connected to the first and second variable frame members 31 and 32 by a plurality of connecting members 6, and the first and second variable frame members 31 and 32 are connected to each other. 32 are connected to the first and second vertical frame members 21 and 22.

  The interposed face material 52 is a flat plate member smaller than the face material body 51, and is disposed above and below the face material body 51. As particularly shown in FIG. 3, the interposed face material 52 is inserted between the webs of the upper frame material 23 and the lower frame material 24, and is interposed between the face material main body 51 and the upper frame material 23 and the lower frame. The web of material 24 is sandwiched. The face material main body 51 and the insertion face material 52 are connected to the upper frame material 23 and the lower frame material 24 by a plurality of connecting members 6.

  As the face material main body 51 and the insertion face material 52, an inorganic board (hard plaster board), a non-combustible decorative board, or a structural plywood can be used. When it is necessary to improve the fire resistance performance of the load-bearing wall panel 1, an inorganic board or a non-combustible decorative board is used as the face material main body 51 and the insertion face material 52.

Next, the operation and action of the load-bearing wall panel 1 of the present embodiment will be described.
Figure 5 is an explanatory view showing a state in which the horizontal force F _H is input to the bearing wall panel 1 of FIG. 1. For example, in the event of an earthquake or strong wind, the horizontal force F _H is input to the frame 2. When the horizontal force F _H is input to the frame 2, the first and second vertical frame members 21 and 22 rotate around the connection point between the upper frame member 23 and the lower frame member 24 as shown in FIG. Then, the frame 2 is distorted.

As described above, since the first and second variable frame members 31 and 32 are displaceable in the extending direction of the first and second vertical frame members 21 and 22, the first and second variable frame members 31 and 32 are displaced in the first direction when the frame body 2 is distorted. And the second variable frame members 31 and 32 are relatively displaced with respect to the first and second vertical frame members 21 and 22. At this time, since the first and second variable frame members 31 and 32 are fastened to the first and second vertical frame members 21 and 22 by the plurality of fasteners 4, the first and second variable frame members 31 and 32 are provided. Friction occurs with the relative displacement between the first and second vertical frame members 21 and 22. Due to this friction, the horizontal force F _H input to the frame 2 is attenuated. Therefore, by using the load-bearing wall panel 1 of the present embodiment in a building, the horizontal force damping performance of the building can be improved. By adjusting the tightening force of the fastening body 4, the magnitude of the friction caused by the relative displacement between the first and second variable frame members 31, 32 and the first and second vertical frame members 21, 22 is adjusted. That is, the horizontal force damping performance can be adjusted.

  In addition, the first and second variable frames are formed by an inner intervening plate 45 having a length extending over a plurality of bolts 40 arranged apart from each other in the extending direction of the first and second vertical frame members 21 and 22. It is inserted between the inner surfaces 31d, 32d of the members 31, 32, the inner washer 42, and the nut 43 (fastening member). Therefore, the friction generated on the inner surfaces 31d and 32d of the first and second variable frame members 31 and 32 can be increased as compared with the case where the inner intervening plate 45 is omitted, and the horizontal force damping performance of the building can be reduced. It can be more reliably improved.

  Furthermore, since the lubricating coating is provided on the inner surfaces 31d and 32d of the first and second variable frame members 31 and 32 and the surface of the inner intervening plate 45, the first and second variable frame members 31 and 32 and the first and second variable frame members 31 and 32 are provided. The relative displacement between the second vertical frame members 21 and 22 can be generated more smoothly. As a result, it is possible to avoid large transient friction, and to obtain more stable horizontal force damping performance.

  Furthermore, since the outer intervening plate 44 provided with a lubricating coating on the surface is provided between the inner surfaces 21a, 22a of the vertical frame members and the outer surfaces 31c, 32c of the first and second variable frame members 31, 32, The relative displacement between the first and second variable frame members 31 and 32 and the first and second vertical frame members 21 and 22 can be more smoothly generated. As a result, it is possible to avoid large transient friction, and to obtain more stable horizontal force damping performance. Further, the material cost can be reduced as compared with the case where the outer intervening plate 44 is omitted and the lubricating coating is provided on the entire inner surface 21a, 22a of the vertical frame member.

  Further, since the plurality of insertion face members 52 arranged so as to sandwich the upper frame member 23 and the lower frame member 24 between the face member body 51 are fastened to the face member body 51, The strength of the upper and lower parts can be improved.

In the load-bearing wall panel 1 of the second embodiment, the first and second variable frame members 31 and 32 are connected to each other by a connection plate 33. The connecting plate 33 can be constituted by a steel plate integrally formed with the first and second variable frame members 31 and 32. More specifically, the connection plate 33 can be a plate portion in which the flanges of the first and second variable frame members 31 and 32 that are in contact with the face material main body 51 are extended. That is, the connecting plate 33 is overlaid on the face material main body 51. The connecting plate 33 is connected to the face material main body 51 by a plurality of connecting members 6.

  The insertion surface member 52 according to the second embodiment extends from the upper frame member 23 and the lower frame member 24 to a position where it comes into contact with the upper edge and the lower edge of the connecting plate 33. Other configurations are the same as those of the first embodiment.

  In such a load-bearing wall panel 1, since the first and second variable frame members 31, 32 are connected to each other by the connection plate 33, when the frame body 2 is distorted as shown in FIG. The stress acting on the main body 51 can be dispersed to the connecting plate 33, and the possibility that the face material main body 51 is damaged by the stress can be reduced. This configuration is particularly useful when the face material main body 51 is formed of an inorganic board or a non-combustible decorative board that is more brittle than a structural plywood. Since the insertion surface member 52 extends from the upper frame member 23 and the lower frame member 24 to the upper edge and the lower edge of the connecting plate 33, the damage of the surface member main body 51 can be avoided more reliably.

Embodiment 3 FIG.

In the load-bearing wall panel 1 according to the third embodiment, the insertion face member 52 extends from the upper frame member 23 and the lower frame member 24 to a position overlapping the upper and lower portions of the connecting plate 33. Further, the insertion face member 52 is connected to the upper and lower portions of the connection plate 33 by a plurality of connection members 6. Other configurations are the same as those of the second embodiment.

In such a load-bearing wall panel 1, since the insertion face material 52 is superimposed on the connection plate 33 and connected to the connection plate 33, when the horizontal force F _H is input to the frame 2, the insertion face material is used. 52 can move integrally with the connecting plate 33. Therefore, the stress applied to the face material main body 51 can be reduced as compared with the case where the insertion face material 52 and the connecting plate 33 move individually, and the possibility that the face material main body 51 is damaged can be reduced. In addition, even if the face material main body 51 is damaged, strength can be exhibited by the interposed face material 52 and the connecting plate 33, and the strength of the load-bearing wall panel 1 as a whole can be more reliably secured.

Embodiment 4 FIG.
FIG. 10 is a perspective view showing a load-bearing wall panel 1 according to a fourth embodiment of the present invention, and FIG. 11 is an exploded perspective view showing the load-bearing wall panel 1 of FIG. The load-bearing wall panel 1 according to the fourth embodiment is obtained by adding a plate-shaped member 8 to the load-bearing wall panel 1 according to the second embodiment. The plate-shaped member 8 is a member disposed so as to sandwich the interposed face material 52 and the connecting plate 33 between the face material main body 51, and is connected to the interposed face material 52 and the connecting plate 33 by the connecting member 6. ing. That is, the insertion surface member 52 and the connection plate 33 are connected to each other via the plate-shaped member 8.

In such a load-bearing wall panel 1, since the insertion face member 52 and the connecting plate 33 are connected to each other via the plate-shaped member 8, the horizontal force F is applied to the frame 2 as in the configuration of the third embodiment. _{When H} is input, the insertion surface member 52 can move integrally with the connecting plate 33. Therefore, the stress applied to the face material main body 51 can be reduced as compared with the case where the insertion face material 52 and the connecting plate 33 move individually, and the possibility that the face material main body 51 is damaged can be reduced. In addition, even if the face material main body 51 is damaged, strength can be exhibited by the interposed face material 52 and the connecting plate 33, and the strength of the load-bearing wall panel 1 as a whole can be more reliably secured.

  The present invention is not limited to the embodiments, and can be embodied by modifying the constituent elements without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in each embodiment. For example, some components may be deleted from all the components shown in the embodiments. Further, components of different embodiments may be appropriately combined.

  For example, in the first to fourth embodiments, the variable frame member 3 is described as being fastened to both the first and second vertical frame members 21 and 22. It may be configured such that it is fastened to only one of the vertical frame members. In this case, the face material may be connected only to one of the first and second vertical frame materials via the variable frame material.

  In the first to fourth embodiments, the lubricating coating is provided on both the inner surfaces 31d and 32d of the flat plate portions 31a and 32a of the first and second variable frame members 31 and 32 and the surface of the inner interposed plate 45. However, the lubricating coating may not be provided on at least one of the inner surface of the first and second variable frame members and the surface of the inner interposed plate.

  Further, at least one of the outer interposed plate 44, the inner interposed plate 45, and the interposed surface member 52 may be omitted. Further, the number of each member may be changed.

  Furthermore, the face material main body 51 may be directly connected to at least one of the first and second vertical frame members 21 and 22.
