Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a horizontal non-bearing wall panel (hereinafter referred to as a panel) which is horizontally stacked between columns of a building, and in particular provided at predetermined intervals on the columns. The present invention relates to a mounting structure for a horizontal non-bearing wall panel excellent in earthquake resistance, which is directly placed on the received steel material.

[Conventional technology and problems]

Conventionally, in order to form a wall body using a panel, a column (a frame member vertically arranged at a predetermined interval on a beam member) is usually vertically arranged so that five or less panels can be stacked. The receiving steel is horizontally fixed by, for example, welding so that it is linearly aligned in the horizontal direction at a predetermined interval, and both ends of the panel are abutted with adjacent panels on the receiving steel. It has been carried out by directly placing a small gap so that it comes to the central portion and laminating a predetermined number of panels thereon, which is repeated. As shown in FIG. 14, each panel is directly fixed by penetrating a bolt 13 protruding from the pillar 6 near the end of the central portion of the panel 1 in the width direction, or as shown in FIG. A cover plate 17 is provided along the outer surface of the vertical joint portion of the panel by hook bolts 16 projecting from the central portion of the pillar 6 for each stage of the panel.
Panel 1 was held down by stopping.

However, if external force such as seismic force or wind pressure is once deformed on the building as shown in FIG. 16, the receiving steel material 7 fixedly mounted on the pillar 6 also tilts due to the deformation of the pillar, and the lower surface of the panel. As a result of the point steel and the receiving steel material contacting each other at a point or a line, cracks 1 are generated in the lower two to three panels as shown in FIG.

When such a panel is used as an outer wall, rainwater penetrates through the cracks, which is not preferable for building maintenance, and when the cracks become large, fragments may fall off, which is dangerous. Atsuta

[Means for solving problems]

As a result of repeated research to solve these problems and obtain a panel mounting structure having earthquake resistance, the present inventors have found that the interlayer deformation angle 1/30
When the deformation is 0 or more, cracks occur in the panel.Therefore, a ridge is provided in the lower portion of both side ends of the panel to be placed on the receiving steel material in contact with the receiving steel material so that the panel is oriented toward the receiving steel material in the inner surface direction. The present invention has been made based on the finding that cracking can be prevented even if the interlayer deformation angle is 1/300 or more by making it swingable as the fulcrum of the protrusion. That is, according to the present invention, a receiving steel material is fixedly installed on a vertically arranged pillar so that a predetermined space is provided in the vertical direction and a straight line is formed in the horizontal direction, and the receiving steel material is straddled over the facing steel material. Place both ends of the horizontal product non-bearing wall panel on top of each other, and place both ends of the adjacent horizontal product non-bearing wall panel with a small gap between them to stack up to 5 horizontal product non-bearing wall panels. Then
In a horizontal product non-bearing wall panel mounting structure that is joined to the pillar directly or through a cover plate by bolts protruding from the pillar, both ends of the lower surface of the horizontal product non-bearing wall panel placed on the receiving steel and the receiver A horizontal product non-bearing wall panel mounting structure in which a ridge is provided between the steel product and the lateral product non-bearing wall panel is configured to be swingable in the in-plane direction with respect to the receiving steel product with the ridge being a fulcrum. Is.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

〔Example〕

FIG. 1 is a side view showing an embodiment of the panel of the present invention, and FIGS. 2 to 9 are side views showing embodiments of the panel of the present invention having different fulcrums.

Reference numeral 1 denotes a panel (horizontal non-bearing wall panel), the main body 2 of which is made of a relatively soft material containing a metal reinforcing material, such as an ALC plate, or
PC board, lightweight concrete board, calcium silicate board, rock wool, extruded board, cement extruded board, ceramic board,
For example, gypsum board. 3 is a protrusion, for example, the second
As shown in the figure, the hemispherical projection 3 is provided so as to project downward,
It is fixed to both ends of the lower surface of the panel body 2 by nailing or the like, and fulcrums 4 are formed between it and the receiving steel material.

3 to 9 show various other embodiments of the fulcrum 4. Thus, in the structure shown in FIG. 3, the protrusions 5 made of an elastic material such as rubber are fixed on the receiving steel material 7 horizontally fixed to the pillars 6 vertically arranged at a predetermined interval on the beam material. The fulcrum 4 is formed by joining the position and forming the concave groove 8 that fits the protrusion 5 at the lower end of the panel body 2.

In the structure shown in FIG. 4, a metal rod is used as a ridge 5 to be joined at a predetermined position on a steel material 7, and a plate 9 having a fitting groove is attached as a protector to a lower end of the panel body 2 to form a fulcrum 4. Is.

In FIG. 5, a ridge 5 is formed by molding a metal plate instead of the metal rod in FIG.

The one shown in FIG. 6 is provided on both sides of the ridge 5 of the elastic material or the metal rod,
Cushioning body 10 made of elastic material such as rubber or sponge
Is arranged to serve as a fulcrum 4 so as to elastically support the swing of the panel and also act as a buffer.

In FIG. 7, the ridge 5 and the shock absorber 10 are integrally formed to form a fulcrum 4. The ridge 5 has a hardness of 60 to 90 ° and a shock absorber.
10 is preferably made of rubber or the like so as to have a hardness of 20 ° to 30 °.

In the structure shown in FIG. 8, a metal plate is formed to provide ridges 5 and small protrusions 11 on both sides to serve as a fulcrum, and the small protrusions 11 act as a buffer.

In FIG. 9, the ridge 5 is surrounded by a bag 12 made of an airtight elastic material such as rubber, and a fulcrum 4 is formed by enclosing a gas such as air inside the bag. is there.

As described above, the fulcrum 4 may be formed in a hemispherical shape as shown in FIG. 2 so as to be in contact with the receiving steel plate in a dot shape, or in a linear shape as in FIGS. 3 to 9. It's good.

Since the panel used in the present invention is configured in this way, the pillars 6 vertically arranged between the beams at intervals corresponding to the length of the panel 1 are vertically separated by a predetermined distance (5 sheets to be stacked). (Corresponding to the sum of the heights of the panels within), and the receiving steel material 7 is fixed horizontally so as to form a straight line in the horizontal direction, and the panel is provided on the receiving metal fitting so as to straddle between the adjacent receiving steel materials 7. Place both ends of the lower surface of 1. This state is shown in FIG. 10 (a) showing the panel 1 as a top view and FIG. 10 (b) showing it as a side view. At this time, both ends of the panel 1 are arranged so as to be slightly spaced apart from the ends of the adjacent panels 1 in the substantially central portion of the pillar 6. Then, in the same manner as in the conventional method shown in FIG. 14, the central portions of both ends are fixed by bolts 13 projecting from the pillars 6, respectively. Then,
Similarly, as shown in FIG. 12 of a normal panel, a predetermined number of panels within 5 sheets are stacked with a slight gap 14 between each panel and bolts are similarly attached to the pillars 6.
Secure with 13. Next, since the next receiving steel material 7 is similarly fixed to the pillar, the panel 1 used in the present invention is placed and fixed to the pillar in the same manner as described above, and 5 or less ordinary panels are stacked in the same manner. Secure to the pillar. Repeating this operation, each gap 14 does not prevent the swinging of the panel, for example, a cushioning material 19 such as rock wool or rock foam material is filled as necessary, and the joint surface is filled with a sealing material 15. A desired wall surface is formed by increasing the waterproof property. As in the conventional method shown in FIG. 15, each panel is attached to the outer surface of the vertical joint portion of each panel by hook bolts 16 projecting one by one from the center of the pillar 6. It is also possible to fix each panel to the holding pillar 6 by stopping the cover plate 17 arranged along the line.

Therefore, even if an external force is applied to the building using the panel mounting structure of the present invention and the pillar 6 swings to the left or right as shown in FIG. 13, the panel members are displaced from each other at the horizontal joints. Following the deformation, the receiving steel material 7 inclines at an angle according to the inclination angle of the column 7, but it is possible to always transmit a constant panel weight to the panel lower surface with the ridge 5 as the fulcrum 4, and to receive the receiving steel material 7 and the lower surface of the panel 1. They do not interfere with each other, so-called mutual interference. Therefore, the crack 18 does not occur in the panel. That is, according to the experiment, when the panel mounting structure of the present invention is used, the receiving steel material 7 and the panel 1 do not interfere with each other for deformation up to an interlayer deformation angle of ± 1/60, and a crack occurs in the panel edge. It never happened.

EFFECTS OF THE INVENTION The present invention is configured such that a ridge is provided between both end portions of the lower surface of the panel and the receiving steel material, and the panel is swingable in the in-plane direction with respect to the receiving steel material using the ridge as a fulcrum. When forming a wall surface, the panels are stacked with a small gap between them, so even if the pillars of a building are deformed by an external force, the panels can easily follow the deformation. The excellent effect of not swinging and damaging the panel is recognized.
