However, as a result of diligent studies by the present inventor, it has been found that the structure of Patent Document 1 has a problem that the range applicable to a building is limited because the seismic resistance is not sufficient.

An object of the present invention is to provide a wall panel mounting structure having a wide range of application to a building.

When a wall panel containing FRP is attached to a wall forming portion of a building, the present inventor does not deform much when a force such as a seismic force is input to the building due to the fact that FRP is a brittle material. I paid attention to the fact that it would be destroyed. Then, in a structure in which a wall panel containing FRP having a low deformation ability is attached to a wall forming portion of a building, a means for increasing the energy absorption amount, which is the product of the force and the amount of deformation when input to the building, is studied diligently. , The present invention has been completed.

At least one of the upper end and the lower end of the wall panel is formed with a through hole for passing the upper fixing means or the lower fixing means. It is configured to allow at least one through hole of the upper end portion and the lower end portion to extend in the vertical direction with respect to a load of a predetermined value or more.

According to the wall panel mounting structure and seismic structure of the present invention, it is allowed that the vertical fracture of the through hole is started when a load exceeding a predetermined value is applied to the building, so that the load is continuously applied.

Here, in Patent Document 1, in order to secure sufficient joint strength between the earthquake-resistant wall and the skeleton such as columns and beams of the building, the joint member is attached to the earthquake-resistant wall with an adhesive and a bolt to reinforce it. It is disclosed that even if there is a gap between the frame and the shear wall, it is only a clearance.

It is further equipped with an adhesive to bond the.

The adhesive between the fixing member and the wall panel allows it to receive a small load. Therefore, the through hole for small load can be prevented from extending building in the vertical direction. Therefore, it is possible to prevent damage to the wall panel due to a weak seismic force, and it is possible to broaden the application range to the building.

The structure of the wall panel 10 shown in FIG. 5 is an example, and can be appropriately changed according to the required performance.

Returning to FIGS. 1 and 2, the upper fixing means 20 is provided so as to be fastened to the upper end portion of the wall panel 10, and the lower fixing means 30 is provided so as to be fastened to the lower end portion of the wall panel 10. There is. The upper fixing means 20 is fixed to the upper end of the wall forming portion of the building, and the lower fixing means 30 is fixed to the lower end of the wall forming portion of the building. The upper fixing means 20 includes a fixing member 21 and a bolt 22. The lower fixing means 30 includes a fixing member 31 and a bolt 32. In the upper fixing means 20, the fixing member 21 and the bolt 22 are integrated, and in the lower fixing means 30, the fixing member 31 and the bolt 32 are integrated.

The fixing members 21 and 31 have a plate shape and extend so as to overlap each other along the horizontal direction of the upper end portion and the lower end portion of the wall panel 10. The fixing members 21 and 31 are in contact only with the front surface and the back surface (panel surface) of the wall panel 10, and are not in contact with the upper end surface and the lower end surface. The fixing members 21 and 31 of the present embodiment are a pair of reinforcing members provided so as to sandwich the upper end portion and the lower end portion of the wall panel 10. The reinforcing member reinforces the yield strength of the wall panel 10, and is, for example, shaped steel (FIG. 2 is C-shaped steel).

Each of the fixing members 21 and 31 is fixed to the wall forming portion by, for example, being fastened to the wall forming portion of the building with a fastening member such as a bolt.

Further, bolts 22 and 32 for fastening to the wall panel 10 are fixed to the fixing members 21 and 31, respectively. The bolts 22 and 32 are penetrated through through holes 11 formed in the upper end and the lower end of the wall panel 10. Therefore, the through hole 11 of the wall panel 10 is a bolt hole in the present embodiment.

As shown in FIG. 2, the structure 1 of the present embodiment further includes adhesives 23 and 33. The adhesives 23 and 33 are provided between the fixing members 21 and 31 and the upper and lower ends of the wall panel 10 in order to connect the fixing members 21 and 31 and the wall panel 10. The adhesives 23 and 33 are provided on the surfaces of the fixing members 21 and 31 facing the wall panel 10, and are preferably provided on the entire facing surfaces.

As described above, the wall panel 10 of the present embodiment is connected to the fixing members 21 and 31 by the bolts 22 and 32 and the adhesives 23 and 33. The fixing members 21 and 31 are connected to the wall forming portion of the building with bolts. Therefore, the wall panel 10 is attached to the wall forming portion via the upper fixing means 20 and the lower fixing means 30. On the other hand, in the present embodiment, both side ends of the wall panel 10 are not fixed to the wall forming portion of the building. Therefore, when a load such as an impact load is applied to the building, both side ends of the wall panel 10 do not interlock with the wall forming portion of the building. In this way, the vertical direction of the wall panel 10 in the structure 1 is restrained, but the side surface of the wall panel 10 is released.

Structure 1, for a given load or greater, and is configured so that at least one through-hole 11 of the upper portion or the lower portion of the wall panel 10 to allow the extension building in the vertical direction. In other words, when a load equal to or greater than a predetermined value is applied, the upper fixing means 20 and the lower fixing means 30 move relative to the wall panel 10. In other words, when a load equal to or greater than a predetermined value is applied, at least one of the through holes 11 starts to break in the vertical direction. In the present embodiment, the load absorbing mechanism of a predetermined value or more is composed of a through hole 11 of the wall panel 10 and bolts 22 and 32 penetrating the through hole 11. Therefore, when the load, such as a predetermined or more impact load is applied, against the force of the wall panel 10 and extending Baso, since the bolts 22 and 32 to move the through hole 11, FRP of the through hole 11 ulcers While being done, it absorbs energy such as impact energy.

The load of a predetermined value or more is a load intended to cause sequential fracture by the fibers of FRP contained in the wall panel 10, for example, a predetermined seismic force, and specifically 80 kN or more, preferably 100 kN or more. Is. The load is a force applied to the building from the outside of the building and is not limited to the impact load.

Here, in the structure 1 of the present embodiment, through holes 11 for passing the upper fixing means 20 and the lower fixing means 30 are formed in each of the upper end portion and the lower end portion of the wall panel 10, and the load is increased to a predetermined value or more. against it, both holes 11 of the upper and lower ends is configured to allow the extension building in the vertical direction. However, in the structure of the present invention, a through hole for passing the upper fixing means or the lower fixing means is formed in the upper end or the lower end of the wall panel, and the upper end or the lower end is penetrated with respect to a load exceeding a predetermined value. it may be configured such holes to allow the extension building in the vertical direction.

Further, in this embodiment, in order through hole 11 extending building in the vertical direction and is made to pass through the bolts 22, 32 into the through hole 11, extending bus means through holes 11 of the present invention in the vertical direction V It is not limited to, and may be, for example, a shaft member serving as a fixed shaft.

Further, in the present embodiment, the upper fixing means 20 and the lower fixing means 30 include the fixing members 21 and 31 fixed to the wall forming portion of the building by the fastening member, but the upper fixing means and the lower portion of the present invention are included. The fixing means may not include a fixing member. In this case, for example, the shaft member penetrating the through hole 11 of the wall panel 10 is directly fixed to the wall forming portion of the building.

Further, in the present embodiment, the wall panel 10 and the fixing members 21 and 31 are connected by two means of the bolts 22 and 32 and the adhesives 23 and 33, but the adhesives 23 and 33 are omitted. You may. The role of receiving the small load of the adhesives 23 and 33 may be omitted, or may be played by another member. In order to play the same role as the adhesives 23 and 33 that receive a small load, for example, a thermosetting resin may be used as the resin constituting the FRP, or spot welding or the like may be used.

Subsequently, as an effect of the structure 1 of the present embodiment, an operation when a predetermined load or more is applied to the structure 1 in which the wall panel 10 is attached to the wall forming portion of the building will be described.

When, for example, a seismic force is applied to the structure 1 as a load equal to or greater than a predetermined value, a horizontal force acts on the wall panel 10. The upper and lower end portions, the through hole 11 of the wall panel 10, since bolts 22 and 32 extends through, by the movement of the bolt 22, through holes 11 extending Biteiki vertically, the through-holes 11 Destruction in the vertical direction of is started. When a load of a predetermined value or more is continuously applied, the fiber bundles of FRP contained in the wall panel 10 forming the edge of the through hole 11 are gradually broken, resulting in sequential failure.

This point will be described mainly with reference to FIG. 7. FIG. 7 shows the load applied to the wall panel 10 of the present embodiment and the amount of deformation thereof. In FIG. 7, the vertical axis shows the load applied to the wall panel 10, and the horizontal axis shows the amount of deformation with respect to each load.

Since FRP is a brittle material, when the load shown in FIG. 7 is x1 or less, it does not break because it is in the elastic region, but since FRP itself has no plastic region, it breaks when the load exceeds x1. However, in this embodiment, for a given load or greater, which is configured as at least one through-hole 11 of the upper portion or the lower portion of the wall panel 10 to allow the extension building in the vertical direction, The load applied to the building is received by the bolts 22 and 32 fixed to the building, and the bolts 22 and 32 move so as to break the through hole 11 of the wall panel 10 in the vertical direction. Therefore, when a load of a predetermined value or more is continuously applied, the fibers in the FRP constituting the through hole 11 are gradually destroyed, so that the amount of deformation shown in FIG. 7 is apparently from y1 to y2. Will have a plastic region of. That is, it is possible to form a region in which the amount of deformation until the wall panel 10 is destroyed is increased from y1 to y2.

The present inventor has 10 through holes 11 having a diameter of 22 mm at the upper and lower ends of a wall panel 10 having a length of 3000 mm in the vertical direction and a length of 1820 mm in the horizontal direction (at the four corners) as shown in FIG. When two are formed in the vertical direction and a load is applied, a load of 100 to 120 kN (x1 in FIG. 7) is in the elastic range, and the load has a shear deformation angle of 10 to 20 (1/1000 rad) (FIG. 7). It has been confirmed that it has y1) and has an apparent plastic region up to a shear deformation angle of 40 to 55 (1/1000 rad) (y2 in FIG. 7) by sequential fracture.

As described above, in the structure 1 of the present embodiment, apparent plastic deformation is caused by the sequential fracture of the through holes provided in the FRP, and the deformability of the FRP panel is acquired. Therefore, the wall panel containing the FRP is obtained. Even if 10 is used, the problem that the deformation performance is small due to the brittle material of FRP is overcome. Since the energy absorption amount when the seismic force or the like is input to the building is obtained by the product of the load and the deformation amount, the structure 1 of the present embodiment can improve the deformation performance, so that the energy absorption amount can be improved. If the amount of energy absorbed can be improved, final destruction such as collapse of a building can be prevented. For this reason, the structure 1 of the present embodiment has an applicable range to the building, as opposed to the conventional technique in which the applicable range to the building to which the wall panel containing FRP is attached is limited due to the small deformation performance. Can be widened.

In particular, stress is concentrated at the four corners of the wall panel 10, but in the present embodiment, through holes 11 are formed at both ends of the upper end portion and the lower end portion of the wall panel 10 at intervals in the vertical direction. doing. Therefore, since the sequential fracture can be effectively generated at the place where the stress is concentrated, the energy absorption amount is improved by increasing the deformation amount. The present inventor has confirmed that when a load equal to or higher than a predetermined value is applied under the above-mentioned conditions, the through holes 11 provided at the four corners at intervals in the vertical direction communicate with each other.

Further, in order to more reliably generate the sequential destruction of the fibers, in the present embodiment, a wall panel containing FRP using continuous fibers, more specifically woven fabric, is used, and the wall panel penetrates at least. In the vicinity of the hole 11, fibers having an inclination of −45 ° or more and 45 ° or less with respect to the horizontal direction are contained.

Further, in order to facilitate the sequential destruction of fibers, the tubular member 12 through which the bolts 22 and 32 are penetrated is used to increase the through hole 11 by the bolts 22 and 32.

Further, since the structure 1 of the present embodiment is intended to be a seismic structure, an adhesive joint is realized as a primary design in the seismic design, and a bolt joint is realized as a secondary design. That is, it is designed so that the adhesives 23 and 33 receive a small load and the bolts 22 and 32 receive a large load. For example, can withstand an adhesive 23, 22 with respect to the seismic intensity of 5 or less seismic force, the bolt 22, 32 is moved to the extended building so the through hole 11 in the vertical direction relative to the seismic force exceeding intensity 5 I can endure it. Therefore, since it is possible to prevent the through hole 11 from starting to be destroyed by a small load, it is possible to prevent the wall panel 10 from being damaged by a weak seismic force.

Further, in order to facilitate the sequential destruction of fibers, in the present embodiment, at least one of the upper end portion and the lower end portion of the wall panel 10 is connected to the wall forming portion of the building, but the side of the wall panel 10 The one is not connected to the wall forming part of the building.

As described above, the wall panel mounting structure and seismic structure of the present embodiment can have a wide range of application to buildings, and thus can be applied to, for example, houses, buildings, hospitals, stations, etc. as buildings. ..

The structure of the wall panel 10 shown in FIG. 5 can be applied to the floor panel 61 and the ceiling panel 62, but can be appropriately changed depending on the required performance.

Since the apartment house 40 of the present embodiment includes the wall panel 10 containing FRP that enhances the proof stress, the proof stress of the housing unit 60 can be improved. By improving the proof stress of the housing unit 60, the proof stress of the structure 50 can be borne by the housing unit 60. Therefore, the proof stress of the apartment house 40 can be maintained even if the proof stress required of the structure 50 is reduced.

Further, since the FRP is lightweight, the housing unit 60 of the present embodiment is a box body having proof stress in spite of its light weight. Therefore, since the housing unit 60 can be relocated while the interior and the like are housed inside the box body, the housing unit 60 is mounted in the living space 52 of the structure 50 by using a crane as shown in FIG. It is also easy to do.
