Description

[Detailed description of the invention] The present invention is a fastening device for installing and fixing wall boards, especially panels such as lightweight aerated concrete boards, asbestos cement extrusion boards, and sandwich boards, to the structure of a building. Regarding.

Conventionally, when constructing and fixing architectural panels to the structure of a building, fasteners with the structure shown in Figures 1 and 2 were usually used, and the fasteners as shown in Figure 3 were used. I am doing it.

In other words, as shown in FIGS. 1 and 2, the conventional fastening metal fittings have a rectangular steel plate 1 having an appropriate thickness at an appropriate inclination angle approximately at the center in the longitudinal direction over its entire length in the width direction. The rectangular steel plate 1 is divided into two steel plate parts 3 and 5 having different phases by providing a bending part 2 having a curved shape. It has a structure with holes 4 for fastening bolts, and when fixing the plate P of panels etc. to the base material (frame) 7 of the structure with the fastening metal fittings, it is necessary to use the third
As shown in the figure, the fastening metal fittings are fixed to the plate P using tightening bolts B and N, and the structure base material 7 is clamped and fixed to the plate P by the other steel plate portion 5 of the fastening metal fittings. It has become.

However, with the above-mentioned conventional fastening fittings, if the tightening pole (B) becomes loose due to the shaking of the building, etc., the fastening fitting may be large and heavy on the upper side of the tightening pole (B), and may become unstable. Since the lower edge 7a of the structure base material 7 is a free end, it rotates around the tightening pole B as an axis and separates from the structure base material 7, causing plates P such as panels to fall off. There was a risk of danger occurring.

Therefore, conventionally, a method has been used in which the other steel plate part 5 of the fastening fitting is welded and fixed to the structure base material 7.
(See Figure 3) This countermeasure is not only cumbersome and requires a lot of effort, but also interferes with welding work depending on the specifications of the structure base material 7, and the work efficiency is extremely low.
This also has the disadvantage of being uneconomical, leading to increased costs.

The present invention was proposed with the aim of solving the above-mentioned drawbacks of the conventional ones. The rectangular steel plate 1 is divided into two steel plate parts 3 and 5 having different phases by providing a bending part 2 with an appropriate inclination angle, and one of the steel plate parts 3 with the inclined bending part 2 as a corner. A fastening metal body with a tightening bolt hole 4 in the center, a width approximately equal to the width of the fastening metal body, and a length slightly longer than the other steel plate portion 5 bordering on the inclined bent portion 2. It has a long length and has a pair of holding members 5a and 5a' that hold the steel plate part 5 at appropriate positions at both ends of one side, and a bending part 6b of an appropriate length at the lower end of the other side to prevent rotation. The present invention relates to a fastening device for architectural panels characterized by comprising a metal fitting 6.

Hereinafter, the present invention will be specifically explained with reference to the rotary protective fitting 6, which is a component of the present device, shown in FIGS. 4 and 5, and an example of the use of the present invention shown in FIGS. 6 and 7.

In those figures, 1 is a rectangular steel plate, 2 is an inclined bent part, and 3 is a rectangular steel plate.
is one steel plate portion bounded by the inclined bent portion 2, 4 is a tightening bolt hole, 5 is the other steel plate portion bordered by the inclined bent portion 2, B is a tightening bolt, N is a nut, P is a panel board,
Reference numeral 7 denotes the base material of the structure, and the structure, function, and mutual relationship of these members are almost the same as those of the conventional fastening metal fittings mentioned above, except for the provision of anti-rotation metal fittings (to be described later). are given the same reference numerals) The above-mentioned members 1 to 5 form a fastening fitting main body.

6 has a width approximately equal to the width of the fastening metal body and a length slightly longer than the length of the other steel plate portion 5 bordering on the inclined bent portion 2, and is placed at appropriate positions on both ends of one side. A pair of holding members 5a and 5a' that hold the steel plate part 5, and a rotation prevention metal fitting that is a part of the main fastening device, which has a bending part 6b of an appropriate length at the lower end of the other side, are used at the same time. As shown in FIGS. 6 and 7, the movement prevention fitting 6 is attached to the steel plate portion 5 of the fastening fitting main body, and its bent portion 6b abuts the lower edge of the structure base material 7, and its upper edge The portion 6C is bent so as to come into contact with the upper end surface of the steel plate portion 5.

In the present invention, the anti-rotation fitting 6 configured as described above is attached to the steel plate portion 5 of the fastening fitting body, and the tightening pin of the fastening fitting body is fixed.
It is characterized in that rotation about B is prevented.

One embodiment of the fastening device of the present invention is constructed as described above, and when fixing panels, etc. to the structure of a building using this device, the method shown in FIGS. 6 and 7 is as follows. As shown in the figure, the anti-rotation fitting 6 is inserted into the steel plate portion 5 of the fastening fitting main body via its pair of holding members 6a and 5a', and its upper end 6C is bent to prevent the rotation. Attach the metal fitting 6 to the specified position on the steel plate part 5 of the fastening metal body, and tighten it by tightening the hole hB.
, If the fastening fitting main body is tightened and fixed to the plate P of the panel etc. via the nut N, the rotation prevention fitting 6 is attached to the structure base material 7.
The plates P of the panels are fixed in place by the steel plate portion 5 of the fastening fitting main body through.

In this case, the lower bent portion 6b of the anti-rotation fitting 6 comes into contact with the lower edge 7a of the structure base member 7, and if the tightening bolt B becomes loose for some reason, the tightening port of the fastening fitting body will ) In addition to preventing rotation around axis B, it is also useful for positioning the base material 7 of the structure.

Since the device of the present invention has the above-mentioned configuration and function, the device according to the present invention can be easily installed by simply attaching a rotation prevention fitting with an extremely simple structure to a conventionally well-known fastening fitting main body. , easy to handle and therefore low cost,
A practical effect can be achieved in that it is possible to realize a fastening device for architectural panels that is free from the risk of accidents such as panels falling off.
