Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a mounting bracket used when attaching hollow panels to beams, etc., and is particularly suitable for easy and reliable installation when installing hollow panels on-site. Furthermore, the present invention relates to metal fittings that are excellent in workability, safety, economy, design, etc. with little variation.

<Prior art> Conventionally, as shown in FIG. 3, for example, hollow panels 5 arranged above and below are attached and fixed to a beam 6 via bolts 1, square nuts 2, Z fittings 3, receiving angles 4, etc. However, bolt holes had to be drilled in the hollow panel 5, a bolt tightening process was required to fasten the metal fittings, and the square nuts 2 rotated idly, making tightening unstable and uneasy. , poor workability,
In addition, when the upper and lower hollow panels 5 are assembled, the metal fittings for the upper hollow panel 5 must necessarily be located below the beam 6 from the assembly position, so the surface accuracy of the upper and lower hollow panels must be improved. Furthermore, separate receiving angles 4 are required at the joint of the upper and lower hollow panels, which has the drawback of poor workability and economical efficiency.

Furthermore, in order to improve these conventional drawbacks, for example, Utility Model Application No. 60-40609 and No. 60-48511 have been developed.
No. 60-172944, etc., have also been developed, but these technologies involve combining a mounting bracket with a special shape and a bottom chord material, or combining a special fixing bracket and mounting material. However, both techniques have disadvantages such as inferior workability, economy, and safety, as well as a lack of consideration for the connection of the upper and lower hollow panels as mentioned above. Ta.

<Problems to be solved by the invention> The metal fitting according to the invention is a completely new technology developed in view of these drawbacks of the conventional technology. To provide a completely new metal fitting that can easily and securely clamp and fix angles from the front and back sides, respectively, and can also accurately achieve mutual surface precision even when upper and lower hollow panels are assembled. It is something.

<Means for solving the problem> The present invention has a cutout portion at a predetermined position on the side.
This is a hollow panel mounting fitting made of a combination of a T-shaped fitting and a substantially T-shaped fitting made of a plate-like body having a bar at the lower end that can be inserted into the notch.

<Function> In the present invention, a substantially U-shaped metal fitting having notches at predetermined positions on both left and right sides as described above and a substantially T-shaped metal fitting having a bar at the lower end that can be inserted into the notch are made to have a tolerance. Since the upper and lower ends of the hollow panel are sandwiched between the substantially U-shaped metal fittings, and the receiving angle is sandwiched between the side surface of the substantially U-shaped metal fittings and the substantially T-shaped metal fitting, the hollow panel can be easily and securely fixed to beams, etc.

Further, by bringing the side surfaces of the substantially U-shaped metal fittings attached to the upper and lower hollow panels into close contact with the side surfaces of the receiving angles, the surface precision of the upper and lower hollow panels can be accurately achieved.

Furthermore, when the middle partition of the hollow panel is inserted into one notch of the approximately U-shaped metal fitting, the movement of the hollow panel in the width direction can be fixed by this metal fitting. can be omitted.

<Example> To specifically explain one embodiment of the metal fitting according to the present invention with reference to figures, in FIGS. 1 and 2, 7 is a substantially U-shaped metal fitting with an open upper part. The lower part of the inner wall has an outward bulge 8, and a notch 9 protrudes from the center of the inner wall into which an unillustrated intermediate partition provided on the hollow panel 5 can be inserted. A packing 10 is laminated on the inner surface of the upper part of this inner wall, and an upper tapered part 11 of the outer wall is slightly opened outward, and a notch part 12 is bored in the center of this outer part. .

Next, reference numeral 13 denotes a substantially T-shaped metal fitting, in which a bar 16 that can be inserted into the notch 12 that is bent slightly outward and protrudes is integrated at the lower center end of a plate-like body 15 having an upper edge 14. It is arranged in series.

When using the metal fittings according to the present invention, the substantially U-shaped metal fittings 7 are attached to the upper and lower ends of the hollow panel 5 as shown in FIG. At the same time, the main body 15 of this metal fitting 13 is dropped between the upper part of the metal fitting 7 and the hollow panel 5, and the upper end of the receiving angle 4 welded to the beam 6 is forcibly inserted between these metal fittings 7 and 13. However, by welding the metal fittings 7 and 13 together and also welding the metal fitting 13 and the receiving angle 4 in the same manner, the hollow panel 5 can be attached and fixed to the beam 6.

In addition, the lower hollow panel 5 achieves accurate mutual surface accuracy with the upper hollow panel 5 by bringing the side surface of the metal fitting 7 attached to the upper end of the hollow panel 5 into close contact with the side surface of the receiving angle 4. I can do it.

<Effects of the invention> Since the metal fittings according to the invention have the above-mentioned structure and function, it is possible to significantly simplify and ensure the construction of hollow panels on-site, and there is no need to tighten bolt sets or the like as in the past. No tools or work are required, and there are no protruding parts such as bolts, so it looks good in terms of design, and if a gasket is provided, variations in panel thickness can be completely absorbed, and the metal fittings can be completely fixed. By installing this, when the panel is inflated, it is possible to omit the edge chamfering of the panel, and it also prevents stress from being generated at the panel edge when the panel bends due to frontal wind pressure loads, etc. By bringing the metal fittings into close contact with the side surfaces of the receiving angle, it has great effects such as making it possible to easily and precisely match the upper and lower panels.
