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 since the square nut 2 rotated idly, the tightening was not reliable and unstable. However, when the upper and lower hollow panels 5 are assembled, the metal fittings for the upper hollow panel 5 must be positioned below the beam 6 from the assembly position, so the upper and lower It is difficult to obtain the surface accuracy of the hollow panels, and furthermore, separate receiving angles 4 are required at the joints of the upper and lower hollow panels, which has the disadvantage 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 substantially inverted U-shaped bracket formed by a load receiving plate and left and right side walls, and a lower part that can be locked to the upper part of the receiving angle. This is a hollow panel mounting fitting characterized by having an integrally protruding U-shaped locking portion.

<Function> As described above, the present invention has a downward U-shape that can be locked to the upper part of the receiving angle at the upper part of one side of the approximately inverted U-shaped metal fitting formed by the load receiving plate and the left and right side walls. Since the locking portion is integrally protruded, the substantially inverted U-shaped metal fitting can be clamped and fixed to the upper end of the hollow panel, and the upper part of the receiving angle can be inserted and locked into the locking portion. This allows the hollow panel to be easily and securely attached to a beam or the like.

Furthermore, if a notch is provided protruding from one side wall of the approximately inverted U-shaped metal fitting, and the middle partition of the hollow panel is inserted into this notch, the movement of the hollow panel in the width direction is controlled by this metal fitting. This makes it possible to omit fixing fittings in the width direction of the hollow panel.

<Example> To specifically explain an example of the metal fitting according to the present invention with reference to the drawings, in FIGS. 1 and 2, 7 is connected to a load receiving plate 8 provided on the upper surface. It is a substantially inverted U-shaped metal fitting formed in a substantially inverted U-shape with the left and right side walls 9, 10, and has a cutout into which a middle partition of a hollow panel (not shown) can be inserted, extending from the load receiving plate 8 to the side wall 9. A notch 11 is formed, and the upper part of the side wall 9 bulges outward to form a bulge 12, and a packing 13 is laminated on the inner surface of the lower part of the side wall 9.

Next, at the upper end of the side wall 10 of the metal fitting 7, a downward U-shaped locking part 14 which can be locked to the upper part of the receiving angle 4 is integrally protruded.

When using the metal fitting according to the present invention, as shown in FIG. The hollow panel 5 is firmly attached and fixed to the beam 6 by locking the portion 14 to the receiving angle 4 welded to the beam 6 and further welding the locking portion 14 and the receiving angle 4 to each other. 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 it is not necessary to tighten bolt sets or the like as in the conventional method. No tools or work are required, and since there are no protruding parts such as bolts, it looks good in terms of design, and if a gasket is provided, variations in panel thickness can be completely absorbed. In this case, a hollow panel can be stably fixed to a beam etc. using a single metal fitting without using a combination of several types of metal fittings, and if a part of the metal fitting is expanded, By installing this, it is possible to omit the edge chamfering process of the panel, and it is also possible to prevent stress from being generated at the panel edge when the panel sways due to frontal wind pressure loads, etc., and it also allows the upper and lower metal fittings to be received on the side of the angle. By bringing the panels into close contact with each other, the upper and lower panels can be easily and precisely aligned, which has great effects.

[Brief explanation of the drawing]

FIG. 1 is an explanatory perspective view of the metal fitting of the present application, FIG. 2 is an explanatory cross-sectional view of its use, and FIG. 3 is an explanatory view showing a conventional example. 1 is a bolt, 4 is a receiving angle, 5 is a hollow panel, 6 is a beam, 7 is a substantially inverted U-shaped metal fitting, 8 is a load receiving plate, 9 and 10 are side walls, 12 is a bulge, 13 is a packing, and 14 is an engagement plate. This is the stop.
