Description

[Detailed description of the invention] The present invention provides a fastening fitting 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 improvements.

Conventional fasteners of this type are generally constructed as shown in FIGS. 1 and 2, and are used as shown in FIG. 3.

In other words, as shown in Figs. 1 and 2, the conventional fastening fittings are provided with a rectangular steel plate 1 having an appropriate thickness, with the long side of the rectangular steel plate 1 located in the central part, and the entire length of the rectangular steel plate 1 in the width direction. A bending part 2 having an inclination angle is provided to make the rectangular steel plate 1 have a different phase.
The steel plate part 3 is divided into two steel plate parts 3 and 5, and a hole 4 for a tightening bolt is provided in the center of one steel plate part 3 with the inclined bent part 2 as a boundary. When fixing the boards P such as panels to the base material (frame) 7 of the structure,
As shown in FIG. 3, the fastening fitting is fixed to the plate P with tightening bolts B, nuts)-N, and the other steel plate portion 5 of the fastening fitting is fixed to the plate P.
The structure base material 7 is clamped and fixed to the plate P.

However, with the above-mentioned conventional fastening fittings, if the tightening bolt B becomes loose due to the shaking of the building, etc., the upper side of the tightening bolt B is large and heavy, and the fastening fitting may become loose. Since the lower edge 7a of the structure base material 7 is a free end,
There was a risk that the bolt P would rotate around the tightening pole B as an axis and separate from the base material 7 of the structure, causing dangers such as the plates P of panels etc. falling off.

Therefore, conventionally, a method has been used in which the other steel plate portion 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 may interfere with welding work depending on the specifications of the structure base material 7, resulting in extremely low work efficiency and high costs. The disadvantage was that it was uneconomical.

The present invention was proposed with the aim of eliminating the drawbacks of the conventional products mentioned above.
A bending part 2 having an appropriate inclination angle is provided along the entire length of the rectangular steel plate 1 in the width direction in the central part of the longitudinal direction of the rectangular steel plate 1.
is divided into two steel plate parts 3 and 5 having different phases, and a hole 4 for a tightening bolt is provided in the center of one steel plate part 3 with the inclined bent part 2 as a boundary. In the fastening fitting, on both sides of the inclined bent part 2 on the side of the other steel plate part 5 with the inclined bent part 2 as a boundary, a surface of the one steel plate part 3 that comes into contact with a plate such as a panel etc. This invention relates to a fastening fitting for architectural panels, characterized in that protrusions 6, 6' having an appropriate width and length that protrude toward the side are provided.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 4 to 6.

In those figures, 1 is a rectangular steel plate, 2 is an inclined bent part, and 3 is a rectangular steel plate.
denotes one steel plate part 4 bordering on the inclined bent part 2, 5 a hole for a tightening bolt, 5 the other steel plate part bounded by the inclined bent part 2, B a tightening bolt, N a nut, P is a panel board, 7
is a structure base material, and the structure, function, and mutual relationship of these members are as described below.Protrusions that contact the lower end surface of the structure base material 7 are provided at both ends of the inclined bent portion 2. Other than the points provided, it is almost the same as that of the conventional fastening fitting described above.

(Equivalent parts are given the same symbols.) 6.6' is
Plates such as panels of the one steel plate section 3 are attached to both ends of the inclined bent section 2 on the other steel plate section 5 side, bordering the inclined bent section 2 at the center in the longitudinal direction of the rectangular steel plate 1. A pair of protrusions 6, 6' with appropriate width and length that can protrude toward the surface in contact with the surface of the panel.As shown in Fig. When it is fastened to the structure base material 7, its dimensions are such that it comes into contact with the lower end surface 7a of the structure base material 7 and prevents the main fastening metal from rotating around the tightening pole) B. is set.

The present invention is characterized in that the protrusions 6, 6' having the above structure are provided.

One embodiment of the fastening metal fitting of the present invention is constructed as described above, and when fixing boards such as panels to the structure of a building using this fastening metal fitting, it is possible to use the fastening metal fitting in the same manner as conventional methods. It is sufficient to perform a simple operation of simply tightening and fixing the main fastening fittings to the plate P of panels etc. using the tightening bolts B and N. , because it is in contact with the pair of protrusions 6 and 6' of the fastening fitting, even if the tightening part B of the main fastening fitting loosens for some reason, the tightening part B of the main fastening fitting will not be connected to the shaft. This rotation is prevented, so that the main fastening fittings will not come off from the structure base material 7, and there is no risk of dangerous accidents such as the plates P of panels falling off.

Since the fastening fitting of the present invention has the above-mentioned structure and function, its structure is extremely simple and easy to handle, and it can be used to attach panels to building structures simply, quickly, and economically. It can be fixed accurately and reliably, and
This has the practical effect of always maintaining the fixed state.
