Description

[Detailed explanation of the invention] This invention uses lightweight concrete wall slabs for the building frame.
In particular, the present invention relates to a wall slab mounting device used to fix the upper and lower ends of the wall slab to a steel beam or the like in a wall structure constructed of ALC slabs.

In recent years, many steel-framed buildings have been constructed using lightweight concrete wall slabs, especially ALC slabs, as curtain walls. It is attached to a beam, etc. using metal fittings or on-site welding, and the hook bolts and mounting hardware at the upper and lower ends of the wall slab are fixed to the wall slab mounting device or through-receiving material. However, on-site welding is unreliable, and the construction cost is high, making it uneconomical.Furthermore, this type of cross-shaped wall plate mounting device has disadvantages such as not being able to adequately follow interstory displacement caused by other earthquakes, etc. was seen.

Therefore, in order to solve the above-mentioned conventional problems, this invention makes it possible to easily position the lower end of the upper floor and the upper end of the lower floor of the wall slab without welding on site. Provided is a wall slab mounting device that can be fitted onto the contact surface, that is, the wall slab fixing surface, can be fixed well, can be erected without damaging the wall slab, and is designed to further improve the ability of the wall slab to follow interstory displacement due to earthquakes, etc. The purpose is to

According to this invention, the wall plate mounting device has a horizontal flange portion and upper and lower contact plates, and the horizontal flange portion is attached to the upper surface of the flange of a steel beam in a wall structure in which a wall plate is built into a building frame. It consists of a mounting member having a cross-shaped cross section to which the wall panel is fixed, and upper and lower wall panel mounting brackets made of plate material and provided near the upper and lower ends of the wall panel so that the hook-shaped portion projects inward. A slot hole with a width sufficiently larger than the thickness of the upper wall plate mounting bracket is provided in the lower abutting plate of the member at a position corresponding to the position of the upper wall plate mounting bracket immediately below the horizontal flange portion, and the groove hole The hook-shaped part of the upper wall plate mounting bracket at the upper end of the wall plate is locked to the lower edge of the wall plate, and the hook-shaped part of the lower wall plate mounting bracket at the lower end of the wall plate is attached to the upper abutment plate of the mounting member. It is fixed to the edge.

Other objects, features, and advantages of this invention will become more apparent from the detailed description given below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the wall slab mounting device 1 of this invention is mainly composed of a mounting member 2 with a cross-shaped cross section having a horizontal flange portion 3, a lower abutment plate 4 extending downward from the horizontal flange portion 3, and an upper abutment plate 5 extending upward from the horizontal flange portion 3, and upper and lower wall slab mounting brackets 12, 13. The horizontal flange portion 3 of the mounting member 2 of this wall slab mounting device 1 is provided with an appropriate opening or hole 6 corresponding to the position of the upper wall slab mounting bracket 12 to be attached to the wall slab 10, and the upper wall slab mounting bracket 12 is attached to the wall slab 10 by the horizontal flange portion 3.
In order to fix the upper wall slab 10 to the lower abutment plate 4, for example, mortar can be filled in. Also, the lower abutment plate 4 has a groove 7 for engaging the upper wall slab mounting bracket 12.
is provided immediately below the horizontal flange portion 3 in correspondence with the position of the upper wall slab mounting bracket 12, and the width of this slot 7 is sufficiently larger than the plate thickness of the upper wall slab mounting bracket 12, and has a margin to fully follow the interlayer displacement of the wall slab 10 due to earthquakes, etc. That is, the upper wall slab mounting bracket 12, which is a well-known sliding metal fitting, is made of a suitable metal plate material so that the hook-shaped portion protrudes inward, and the hook-shaped notched portion is engaged with the horizontal edge of the slot 7, so that the upper wall slab mounting bracket 12 can slide along the edge of this slot 7. In addition, the upper abutment plate 5 is provided with notches in the vertical direction at equal intervals in the longitudinal direction and at certain intervals in the illustrated embodiment, but it is of course possible to provide a continuous lengthwise direction without such notches. In addition, in order to attach the upper wall slab mounting bracket 12 to the wall slab 10, a metal plate material is provided on the wall slab 10.
The upper wall slab mounting bracket 12 may be inserted and attached at the time of installation, or may be attached and fixed in advance before installation, or may be embedded and molded together with the wall slab when molding the wall slab. For such upper wall slab mounting bracket, a slide flat metal fitting known as a mounting bracket for a well-known slide construction method is used, and a suitable hook-shaped portion is suitably provided. Similarly, the lower wall slab mounting bracket is made of a suitable metal plate material, and a well-known mounting bracket for a slide construction method with a hook-shaped portion is used.

Next, using the wall plate mounting device 1 of this invention, the wall plate is attached as follows. First, the horizontal flange portion 3 of the mounting member 2 is fixed to the upper surface of the upper flange of the steel beam 20 of the building by appropriate means such as welding. The mounting member 2 fixed to the steel beam 20 in this way
To fix the lower floor wall slab 10 to The hook-shaped part of the metal fitting 12 is locked in the slot 7 part of the lower contact plate 4 of the mounting member 2, and then the upper wall plate mounting fitting 12 is temporarily nailed to the wall plate 10, and the hole in the horizontal flange part 3 is fixed. Insert and fill mortar from 6 to wall plate 1
The upper wall plate mounting bracket 12 is fixed to the upper wall plate 0, thereby fixing the wall plate 10 to the mounting member 2 of the steel beam 20. Of course, it is preferable to fix the lower end of the wall slab 10 at the same time as the upper end 10' of the wall slab 10 is fixed. That is, the fixing of this lower end is similar to the fixing of the lower end 11' of the upper floor wall slab 11 shown in FIG. First,
The lower end 11' of the upper wall slab 11 is brought into contact with the upper abutting plate 5, and the lower wall slab mounting bracket 13 is attached to the upper abutting plate 5.
The hook-shaped part of the lower wall plate mounting bracket 13 is temporarily fixed and nailed to the wall plate 11, and then, or at the same time, the upper end of the wall plate 11 is attached to the lower abutting plate attached to the upper floor steel beam. After abutting and fixing in the same manner as described above, mortar is inserted and filled into the joints between the wall slabs 11 and fixed. In this way, the wall slab can be fixed at its upper and lower ends respectively to the steel beam, preferably simultaneously.

Wall plate mounting device 1 of this invention configured in this way
According to the above, if the mounting member 2 is accurately attached to the steel beam 20, the wall slabs 10 and 11 can be simply and easily fixed vertically to the steel beam 20, without using a welding machine or the like as in the conventional method. , the wall slab can be fixed easily and reliably, and more economical construction is possible. Furthermore, based on the dimensional relationship between the width of the slot and the thickness of the upper wall plate mounting bracket, the hook-shaped portions of the lower and upper wall plate mounting brackets attached to the wall plate are connected to the upper abutting plate of the wall plate mounting device. Since it is held so that it can slide an appropriate distance along the upper edge of the upper edge and the edge of the slot in the lower abutment plate, it can satisfactorily follow the displacement between the floors of the building due to earthquakes or the like.

As described above, the wall plate mounting device of this invention has a simple structure, which makes it easy and accurate to erect the wall plate, making it an economical structure for residential construction.
