Description

  The present invention relates to a load-bearing wall panel, and more specifically, a pair of frame members made of thin lightweight steel, a first surface member such as a folded plate provided across the pair of frame members, and the first surface. The present invention relates to a load-bearing wall panel including a second face material provided along the material.

Conventionally, as a load-bearing wall panel, a panel having a multilayer structure in which a face material is fixed to one side or both sides of a frame has been proposed (see, for example, Patent Documents 1 to 3).
In the panel described in Patent Document 1, the metal flat plate is subdivided by a plurality of reinforcing materials (ribs) arranged at a fine pitch inside the frame, thereby preventing the shear buckling of the metal flat plate when a shear force is applied. It is configured to be able to.
Further, in the panels described in Patent Documents 2 and 3, the thin steel plate and the plywood (or gypsum board) are integrated by forming a face material by bonding a plywood or gypsum board to one or both sides of the thin steel plate. The panel is designed to improve the shear strength of the panel.

Moreover, the panel which joined the folded plate as a face material to the frame is also utilized as a load-bearing wall panel (for example, refer patent document 4).
In the panel described in Patent Document 4, when a horizontal force such as an earthquake acts, the yield strength at which the valley of the folded plate bearing the shearing force yields and the bearing pressure around the screw fixing the folded plate to the frame By appropriately setting the yield strength due to the deformation, it is possible to prevent a sudden decline in the yield strength due to the shear buckling of the folded plate, the deformation of the frame, and the like, and the deformation performance of the panel can be improved.

However, the conventional panels described in Patent Documents 1 to 4 have the following problems.
That is, in the panel described in Patent Document 1, it is necessary to make the pitch of the reinforcing material fine in order to prevent shear buckling of the metal flat plate, and the number of reinforcing members increases, so the weight and manufacturing cost of the panel are increased. There is a problem that increases.
In addition, in the panels described in Patent Documents 2 and 3, since the thin steel plate and the plywood or gypsum board are bonded, the shear strength of the entire panel can be improved, but the plywood or gypsum board bears the shearing force. In a large deformation area, the plywood or the plaster board is damaged, and if it is damaged, there is an inconvenience that repair work and costs are required.
On the other hand, in the panel described in Patent Document 4, since the shear strength of the panel is controlled by supporting and deforming the folded plate around the screw, the deformation strength is improved, but the shear strength itself is not increased. It is impossible to effectively utilize all the yield shear strength possessed by.

  An object of the present invention is to provide a load-bearing wall panel that can be reduced in weight and cost, and that can effectively improve the energy absorption performance by effectively utilizing the shear strength while ensuring the deformation performance of the face material. It is in.

  The load-bearing wall panel of the present invention is provided along at least one pair of frame members facing each other, a first face member provided across the pair of frame members, and at least one surface of the first face member. A load-bearing wall panel comprising a second face material, wherein the first face material is fixed by first fixing means along a longitudinal direction of the pair of frame members, and the first face material It is composed of a steel surface material set so as to yield a shear with a predetermined shear force acting in the in-plane direction, and the second surface material allows shear deformation of the first surface material and the first surface. It is attached to at least one of the frame material and the first surface material via a second fixing means capable of regulating the out-of-plane deformation of the material.

  According to the present invention described above, the first face material composed of the steel face material is shear yielded, so that the yield shear strength is fully utilized and the out-of-plane deformation of the first face material is second. By regulating the face material, it is possible to prevent out-of-plane buckling of the sheared and yielded first face material, and to ensure the deformation performance of the first face material even after yielding without causing a sudden decrease in yield strength due to buckling. can do. Therefore, since it is possible to prevent out-of-plane buckling of the first face material without providing a reinforcing material at a fine pitch as in the prior art, a predetermined shear strength can be achieved while reducing the weight and cost of the panel. A panel having excellent deformation performance can be formed, and the energy absorption performance of the panel can be improved. Further, since the second fixing means for attaching the second face material is configured to allow shear deformation of the first face material, even if the first face material undergoes shear deformation, the second face material is Shear deformation does not occur, that is, no shear force acts on the second face material (or only a small shear force acts), and damage to the second face material can be prevented. Therefore, even after the seismic force acts on the panel and the energy is absorbed by shear deformation of the first face material, the second face material can maintain the initial state, and the repair can be made unnecessary. The burden of expenses etc. can be reduced.

At this time, in the load-bearing wall panel of the present invention, the first face member is composed of a folded plate having a peak portion and a valley portion extending in a direction across the pair of frame members, and the valley portion. The first fixing means includes a first fixing member that passes through one of the valley portion of the folded plate and the frame material and is fixed to the other. It is preferable.
According to such a configuration, the first face material is formed of a folded plate, and the trough is fixed to the frame member by the first fixing member, so that the stress at the time when the trough of the folded plate is shear yielded is framed. It is possible to reliably transmit to the material, and to ensure that the shear strength of the panel is exhibited.

And in the load-bearing wall panel of the present invention, the second face material is provided in contact with the crest of the folded plate from the opposite side of the frame material, and the second fixing means is the second face material. And a second fixing member that penetrates through the peak portion or valley portion of the folded plate and is fixed to the frame member.
According to such a configuration, as described above, in the mechanism of shear yielding the valley portion of the folded plate, the deformation of the valley portion having shear yielded can be achieved by providing the second face material in contact with the mountain portion of the folded plate. Transmission to the second face material can be made difficult, and damage to the second face material can be prevented more reliably.

Furthermore, in the load-bearing wall panel according to the present invention, an insertion hole having a larger diameter than the shaft diameter of the second fixing member is formed in a peak portion or a valley portion of the folded plate, and the second fixing portion is formed in the insertion hole. It is preferable that the member is inserted.
According to such a configuration, an insertion hole having a large hole diameter is formed in the peak portion or valley portion of the folded plate through which the second fixing member passes, and the shaft portion of the second fixing member is inserted into the insertion hole. Thus, the second fixing member and the folded plate can be prevented from interfering with respect to the in-plane direction of the panel, and transmission of shearing force from the first face material to the second face material in the in-plane direction can be reliably blocked. Can do.

On the other hand, in the load-bearing wall panel of the present invention, the second face material is provided as a pair along one and the other face of the first face material, and the second fixing means is the pair of second face materials. And a second fixing member that penetrates the first face material, and a fastening member that tightens the pair of second face materials in an approaching direction together with the second fixing member, and the first face material or An insertion hole having a larger diameter than the shaft diameter of the second fixing member may be formed in the second face material, and the second fixing member may be inserted through the insertion hole.
According to such a configuration, it is possible to prevent out-of-plane buckling of the first face material by sandwiching between the pair of second face materials. Even in this case, the transmission of the shearing force from the first surface material to the second surface material is ensured by inserting the second fixing member through the insertion hole having a large hole diameter formed in the first surface material or the second surface material. Can be blocked.

At this time, in the load-bearing wall panel of the present invention, the first face member is composed of a folded plate having a peak portion and a valley portion extending in a direction across the pair of frame members, and the valley portion. The first fixing means includes a first fixing member that passes through one of the valley portion of the folded plate and the frame material and is fixed to the other. The second fixing member of the second fixing means is preferably provided so as to penetrate the peak portion of the folded plate.
According to such a configuration, even in a structure in which out-of-plane buckling of the first face material is prevented by being sandwiched between the pair of second face materials, the first face material is configured by the folded plate and the valley portion is used as the frame material. When fixed, by passing the second fixing member through the peak portion and attaching the pair of second face materials, the deformation of the valley portion where the shear yield has occurred can be made difficult to be transmitted to the second face material. Damage can be prevented more reliably.

Furthermore, in the load-bearing wall panel of the present invention, it is preferable that the hole diameter of the insertion hole is formed large in a range of 200% to 400% of the shaft diameter of the second fixing member.
According to such a configuration, by appropriately setting the hole diameter of the insertion hole and the shaft diameter of the second fixing member, the second face material can be reliably held and the first face material can be changed to the second face material. By interrupting the transmission of the shearing force, it is possible to reliably prevent the second face material from being damaged.

In the load-bearing wall panel of the present invention, the second face material is an interior panel provided to cover an indoor side that is one side of the first face material, and a house that is the other side of the first face material. It is preferable that it is comprised by the at least one panel of the exterior panel provided covering the outer side.
According to such a structure, a 2nd surface material is comprised with the interior panel for foundation | substrates, such as a gypsum board provided in the indoor side of a 1st surface material, the heat insulation board provided in the outdoor side of a 1st surface material, By configuring the second face material with an exterior panel such as an exterior base, the second face material can be effectively used as an interior base or exterior base in addition to the function of preventing buckling of the first face material. . Even when the second face material is used as the interior / exterior base, since the damage of the second face material can be prevented as described above, the repair can be made unnecessary and the burden of repair costs and the like can be reduced.

  According to the load-bearing wall panel of the present invention as described above, the out-of-plane buckling of the first face material subjected to shear yield is prevented by regulating the out-of-plane deformation of the first face material with the second face material. The deformation performance of the first face material can be ensured even after yielding without causing a sudden decrease in yield strength due to buckling. Accordingly, since the energy-bearing wall panel of the present invention can effectively absorb energy such as earthquakes, the panel can be used to construct a highly durable and economical bearing wall and prevent damage to the second face material. Since it can be done, the burden of repair costs after energy absorption can be reduced.

[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The load-bearing wall panel 1 according to the present embodiment is fixed to a suitable floor column and upper and lower beams in a frame wall construction method or the like, and is used as a load-bearing wall of the building. As shown in FIG. 2, a frame 2 that is a four-frame framework from a thin lightweight steel (lip groove steel), and a first face material (steel) that is fixed to an indoor side surface that is one surface of the frame 2. A folded plate 3 as a surface material) and an interior panel 4 as a second surface material attached to the indoor side further than the folded plate 3. In other words, the framed wall construction building is a steel house in which the frame 2 of the load-bearing wall is composed of thin lightweight steel and the face material that is a horizontal force bearing element (seismic element) is composed of the folded plate 3. The outer wall of this building is composed of a heat insulating material or exterior material (siding) provided on the outdoor side of the load bearing wall panel 1 and an interior finishing material such as a cloth provided on the interior panel 4 of the load bearing wall panel 1. It is configured. The load-bearing wall panel 1 is not limited to the one constituting the outer wall of the building, but may be used as an inner wall provided with an interior finishing material on one side or both sides of the panel 1.

  The frame 2 of the load-bearing wall panel 1 includes an upper frame member 21, a lower frame member 22, and left and right vertical frame members 23, which are frame members made of lip channel steel, and an upper frame member 21 and a lower frame member 22. And a vertical beam 24 constructed over the road. Each of the frame members 21, 22, 23 and the vertical rail 24 has a web 25 extending in the indoor / outdoor direction and a pair of flanges 26 continuous to both the indoor side and outdoor side ends of the web 25. It is formed in a U shape (C shape). In such a frame 2, a pair of frame members is constituted by the left and right vertical frame members 23, and the folded plate 3 is fixed to the left and right vertical frame members 23 by a plurality of tapping screws 5 as first fixing means. The interior panel 4 is fixed by a plurality of long screws 6 as second fixing means. The folded plate 3 has upper and lower edges fixed to the upper frame member 21 and the lower frame member 22 with tapping screws 5, and a central portion in the left-right direction is fixed to the vertical rail 24 with tapping screws 5. The frame 2 is not limited to the one having the vertical bars 24, and the vertical bars 24 may be omitted, or two or more vertical bars 24 may be provided.

  The folded plate 3 is formed to have a crest 31 and a trough 32 that are alternately provided so as to extend between the left and right vertical frame members 23, and an inclined portion 33 that connects them. The tapping screws 5 are joined to the vertical frame member 23 and the vertical rail 24. The tapping screw 5 is a first fixing member that penetrates the trough 32 of the folded plate 3 from the opposite side of the frame 2 and is screwed to the flange 26 on the outdoor side of the vertical frame member 23 and the vertical beam 24. By tightening such a tapping screw 5, the folded plate 3 is joined to the frame body 2 with the indoor side surface of the valley portion 32 abutting against the flange 26. Such a folded plate 3 functions as an oblique member in which each valley portion 32 bears a shearing force when a horizontal force such as an earthquake load acts on the load bearing wall panel 1, and the inclined portion 33 and the mountain By forming a truss mechanism in which the portion 31 functions as a string member, it is possible to bear a horizontal force, and the trough portion 32 is configured to exhibit a predetermined shear strength in a mechanism state in which the trough portion 32 shears and yields. .

  The interior panel 4 is made of a non-metallic plate material such as a gypsum board, and both left and right edges thereof are fixed to the vertical frame member 23 by long screws 6. As shown in FIG. 3, the long screw 6 penetrates the interior panel 4 from the side opposite to the frame body 2, further penetrates the valley portion 32 of the folded plate 3, and the flange 26 on the outdoor side of the vertical frame member 23. The interior panel 4 is in a state in which the indoor side surface of the interior panel 4 is brought into contact with the surface of the crest 31 of the folded plate 3 by tightening such a long screw 6. It can be attached to the frame 2. Even when the valley portion 32 of the folded plate 3 bears a shearing force as described above, the interior panel 4 attached in this manner abuts against the peak portion 31 of the folded plate 3. Out-of-plane deformation to the outside is regulated by the interior panel 4 so that the entire folded plate 3 can be prevented from buckling. Further, an insertion hole 34 having a large hole diameter in the range of 200% to 400% of the shaft diameter of the long screw 6 is formed in advance in the trough 32 of the folded plate 3, and the long screw 6 is formed in the insertion hole 34. By being inserted, even when the trough 32 of the folded plate 3 is sheared and deformed, the trough 32 and the long screw 6 are configured not to interfere with each other.

The load-bearing wall panel in the present embodiment is not limited to the load-bearing wall panel 1 shown in FIGS. 1 to 3, and may be the load-bearing wall panel 1 </ b> A shown in FIG. 4.
That is, in the load-bearing wall panel 1A shown in FIG. 4, the long screw 6 that is the second fixing means (second fixing member) penetrates the interior panel 4 from the side opposite to the frame body 2, and further, The interior panel 4 is configured to be attached to the frame body 2 by passing through the portion 31 and screwing into the flange 26 on the outdoor side of the vertical frame member 23. Here, the above-described insertion hole 34 for inserting the long screw 6 is not formed in the peak portion 31 of the folded plate 3, and the peak portion 31 penetrates when the long screw 6 is screwed. Therefore, the long screw 6 is provided in a state of being engaged with the peak portion 31 in the in-plane direction. In such a load-bearing wall panel 1A, as described above, the out-of-plane deformation of the folded plate 3 toward the outdoor side is restricted by the interior panel 4, thereby preventing the entire folded plate 3 from buckling. ing. Further, although the crest 31 of the folded plate 3 and the long screw 6 are engaged, the engagement position is separated from the trough 32 by the crest height of the crest 31, so that the trough 32 is subjected to shear deformation. It can be absorbed by the fall of the long screw 6, so that the interior panel 4 is not easily deformed. In the load bearing wall panel 1A, the long screw 6 may be inserted by forming an insertion hole similar to the insertion hole 34 in the peak portion 31 through which the long screw 6 passes.

According to the above embodiment, the following effects can be obtained.
That is, since the internal panel 4 prevents the entire folded plate 3 from buckling, and the shear deformation in the in-plane direction generated in the folded plate 3 is not transmitted to the interior panel 4 or is difficult to be transmitted, the yield shear strength of the folded plate 3 is reduced. The deformation performance up to and after the yielding can be ensured, and the interior panel 4 can be prevented from being damaged. Therefore, since it is not necessary to provide a large number of reinforcing materials at a fine pitch to prevent out-of-plane buckling of the folded plate 3, energy absorption is achieved while reducing the weight and cost of the load-bearing wall panels 1 and 1A. A load-bearing wall with excellent ability can be constructed. Furthermore, since the interior panel 4 that prevents buckling of the folded plate 3 also serves as a base material for interior finishing, the number of members can be further reduced and the cost can be reduced. Since the transmission of the deformation is suppressed and the damage can be prevented, the repair of the interior panel 4 and the interior finish material after the earthquake can be made unnecessary or simplified, so that the burden such as the repair cost can be reduced.

[Second Embodiment]
Next, the load-bearing wall panel 1B according to the second embodiment of the present invention will be described with reference to FIGS.
In the present embodiment, the number of attached second face materials and the attached form are different from those of the first embodiment, but other configurations are substantially the same as those of the first embodiment. Hereinafter, the differences will be described in detail.

An interior panel 4A similar to the interior panel 4 is provided as an inner second face material, and a heat insulating panel 7 is provided as an outdoor second face material. The interior panel 4A and the heat insulating panel 7 are attached to the folded plate 3 by a long screw 6 (second fixing member) and a washer 8 (clamping member) as second fixing means.

  Specifically, the long screw 6 penetrates the interior panel 4A from the side opposite to the frame 2 and penetrates the mountain 31 of the folded plate 3 and also penetrates the heat insulating panel 7 and then the washer 8 is attached to the tip thereof. It is designed to be screwed together. Therefore, by tightening the long screw 6 and the washer 8, the indoor side surface of the interior panel 4A is brought into contact with the surface of the mountain portion 31 of the folded plate 3, and the outdoor side surface of the heat insulating panel 7 is contacted with the valley portion 32 of the folded plate 3. The interior panel 4A and the heat insulation panel 7 are attached to the folded plate 3 in a state where they are in contact with the surface, and by sandwiching between the interior panel 4A and the heat insulation panel 7, the out-of-plane deformation of the folded plate 3 is restricted, and the folded plate 3 can be prevented from buckling. Further, an insertion hole 35 having a large hole diameter in the range of 200% to 400% of the shaft diameter of the long screw 6 is formed in the peak portion 31 of the folded plate 3 in advance, and the long screw 6 is provided in the insertion hole 35. By being inserted, even when the folded plate 3 is deformed by shear yielding, the crest 31 and the long screw 6 are configured not to interfere with each other.

  Since the same effect as that of the load-bearing wall panels 1 and 1A can be obtained by the load-bearing wall panel 1B, the heat-insulating panel 7 that prevents buckling of the folded plate 3 also serves as a heat-insulating material. Can be further reduced to reduce the cost. Furthermore, since the crest 31 of the folded plate 3 and the long screw 6 do not interfere with each other, and the deformation of the folded plate 3 is difficult to be transmitted to the interior panel 4A and the heat insulation panel 7, the interior panel 4A and the heat insulation panel 7 are damaged. This can be prevented and repair after an earthquake can be made unnecessary or simplified, so that the burden of repair costs and the like can be reduced.
