Description

[Detailed description of the invention] This invention relates to an installation device for concrete wall panels that constitute the curtain wall of a building, and is particularly suitable for use as an installation device for lightweight aerated concrete (hereinafter referred to as ALC) wall panels. be.

Conventionally, to install this type of wall panel, as shown in Utility Model No. 58-85008 shown in Figures 3 and 4,
A device for attaching panels by inserting a steel bar c into a hole b formed in the edge face a of an exterior wall panel A, and stacking and welding a flat steel piece e at the base of the steel bar c onto the flange surface of a reinforcing steel material d. There is. However, in this device, the base of the steel bar is fixed to the reinforcing steel, so the panel cannot follow the interlayer displacement of the structural frame during an earthquake, and there is a risk of cracking due to shear force. In addition, the work of welding the base of the steel bar and the reinforcing steel at the panel installation site reduces construction efficiency.

Furthermore, as shown in FIG. 5, there is a method in which the panel A is held down from the indoor surface f using plate-shaped metal fittings i and bolts h, but the plate-shaped metal fittings are exposed on the surface. To prevent this, Figures 6 and 7
As shown in the figure, there is also a method of providing a counterbore k in the erected panel A and fixing the panel A to an angle o welded to the beam steel frame using bolts h, washers m, and nuts n. However, with this method, it is necessary to fill the pit hole K with repair mortar P and to finish the spot repaired part in the same condition as the panel surface.
The work is complicated and construction efficiency decreases. In addition, this pit repaired area may remain as uneven color after exterior finishing with architectural spray paint, etc., or may cause contact between the base material and the repaired mortar due to drying shrinkage of the repaired mortar or vibration of the bolts during an earthquake. This may impair the design of the panel surface, such as cracks appearing at the border.

Furthermore, as shown in FIG. 8, there is also a method in which a panel mounting fitting q is buried inside the panel in advance, and the panel is mounted from the indoor surface using bolts r. However, with this method, it is necessary to embed the mounting fittings in advance at a predetermined position within the panel during the panel manufacturing process, and the mounting position may be changed during on-site construction or the panel may be cut before use. In such cases, the position of the embedded metal fitting cannot be changed, making it difficult to adapt to the situation.

This invention was developed with the aim of solving the above-mentioned problems, and allows the panels to follow the inter-story displacement of the structural frame during an earthquake, has high construction efficiency, does not impede the design, and can be installed at the panel installation site. To provide a wall panel mounting device capable of adjusting the length of a panel by cutting at. The details will be explained below with reference to illustrated embodiments.

FIG. 1 is a longitudinal sectional view illustrating an embodiment of this invention. In the figure, 1 and 2 are an upper layer panel and a lower layer panel, and 3 is a beam steel frame. The metal fittings used include a receiving metal fitting 4, an angle-shaped metal fitting 5, a lower mounting metal fitting 6, and a bar-shaped steel material 7 for mounting the lower panel. The metal support 4 is attached to the beam steel frame 3 by welding, and a vertical flange 4a is provided to project from the beam steel frame 3. This vertical flange 4a has a horizontally elongated hole 4b into which the angle-shaped metal fitting 5 is inserted, and a screw insertion hole 4c in contact with the lower part of the horizontally elongated hole 4b. The angle-shaped metal fitting 5 consists of a panel self-weight bearing flange 5a and a vertical flange 5b in which a groove 5c for screw insertion is formed. The lower mounting hardware 6 has a lightning bolt-shaped cross section, and has a bolt insertion hole 6a in the upper part and a screw insertion groove 6b in the lower part. The bar-shaped steel material for attaching the lower panel is bent into an L shape, and one end is threaded 7a.

When installing the upper and lower panels 1 and 2, as shown in Fig. 2, the brackets 4 are fixed to the beam steel frame 3 in advance, and a circular shape is formed perpendicularly to the upper horizontal edge surface of the lower panel. Insert one end of the bar-shaped steel material 7 into the hole, and insert the other end, which protrudes from the back of the panel and has been threaded 7a, into the screw insertion hole 4c formed in the vertical flange 4a of the bracket 4. The lower panel is built in so that the back of the lower panel 2 is in contact with the lower panel. The circular holes formed on the edge side of the panel may be pre-formed at the panel manufacturing site, but they can be easily drilled with a hand-held electric drill that is commonly used at the construction site. Therefore, it can also be applied to panels whose length is adjusted by cutting on site.

Next, the horizontally elongated hole 4 of the vertical flange 4a of the receiving part 4 is
Insert the dead weight bearing flange 5a of the angle-shaped metal fitting 5 from the inside of the vertical flange 4a into b, and insert the angle-shaped metal fitting 5 so that the threaded protruding portion of the bar-shaped steel material 7 is inserted into the screw insertion groove 5c. Attach.

As mentioned above, installation of the metal fittings is very easy as the metal fittings can be fitted into holes whose positions have been adjusted in advance.

Next, sandwich the vertical flange 4a of the receiving angle 4 and the vertical flange of the angle-shaped metal fitting 5, and insert the lower part so that the threaded protruding portion of the bar-shaped steel material 7 is inserted into the screw insertion groove 6b of the mounting hardware 6. The mounting bracket 6 is attached to the vertical flange 5b of the angle-shaped bracket 5.
The lower panel 2, the angle-shaped fitting 5, and the lower mounting fitting 6 are fixed to the receiving metal 4 by stacking them on the inside of the bar-shaped steel material 7, screwing nuts 8 into the threaded portions of the bar-shaped steel material 7, and tightening them.

Next, the upper panel 1 is placed on the self-weight bearing flange 5a of the angle-shaped metal fitting 5, and the lower mounting metal fitting 6 is attached.
Upper panel 1 is fixed by screwing bolts 9 into the inner surface of panel 1 through bolt insertion holes 6a.

As described above, when a panel is attached to a structure using the mounting device of the present invention, the panel can be attached to the bolt insertion holes 6a of the lower mounting hardware and the screw insertion holes 4 of the bracket 4.
It becomes possible to cause a rotational shift around c, and the panel causes a rotational movement to follow the interstory displacement of the structural frame during an earthquake.

The present invention has the above-mentioned structure, and the holes formed on the panel edge surface can be easily drilled with a hand-held electric drill commonly used at construction sites, so they can be cut to length at the panel installation site. It can also be applied to panels that have been adjusted. Each mounting bracket can be installed by simply fitting it into a pre-formed hole and tightening bolts on site, making installation easy and highly efficient.

Furthermore, since the panel can rotate around the bolt insertion holes of the lower mounting hardware and the screw insertion holes of the receiving metal,
The panel has the function of rotating and following the displacement between the layers of the structural frame during an earthquake.
