Description

[Detailed Description of the Invention] The present invention relates to a metal fitting for connecting and suspending ceiling base materials in a lightweight steel frame ceiling base structure.

Conventional lightweight steel frame ceiling base structures were formed by connecting the field edge orthogonally to the lower surface of the field edge support suspended horizontally, and extending the ceiling board to the lower surface of the field edge. In this case, the field edge support and the field edge must be connected orthogonally, and the field edge and the ceiling board must be attached with screws, etc., which requires a lot of ceiling construction and construction work, and various metal fittings are also required. there was.

Therefore, in recent years, a ceiling base material A as shown in FIG. 1 has been used.

That is, a ceiling plate mounting piece C that is horizontally bent outward is provided in series at the lower end of both side plates B forming a frame with a rectangular cross section, and a connecting groove is formed by folding the mounting piece C upwardly and inwardly. be.

The present invention involves sequentially connecting base materials of standardized lengths as described above in four directions, forming a large number of squares with the base materials on the ceiling construction surface, and placing the ceiling board within these squares. It provides metal fittings for hanging.

Below, one embodiment of the present invention will be described in detail according to the drawings.
In FIGS. 3 and 3, reference numeral 1 indicates a hanging metal fitting, and 2 indicates a connecting metal fitting. A bolt insertion hole 5 is formed, and a small hole 6 for inserting a wire is formed in the upper part of the connecting piece 4 or the metal plate 3, that is, in the upper part of the hanging fixture 1.

At the bottom of the metal plate 3, a locking piece 7 having a length larger than the thickness of the metal plate 3 is arranged in series, and above the locking piece 7, the metal plate 3 has a cut-and-raised piece that slopes downward. 8 is provided in a protruding manner, and the distance between the lower end of the cut-and-raised piece 8 and the upper end of the locking piece 7 is approximately the same as the thickness of the fixing plate of the connecting fitting, which will be described later.

The connecting fitting 2 is a rectangular plate with a semicircular or right-angled recess 9 provided therein, and is installed horizontally.
Connecting pieces 12 are arranged horizontally outward on the four sides of the fixing plate 11 around the fixing plate 11 having a through groove 10 that is about the same width as the width of the metal plate 3 and smaller than the width of the locking piece 7. , and regulating pieces 13 are bent downward at right angles to both edges of each connecting piece 12 in the protruding direction.

At the bottom of each section 9 of the fixing plate 11, there is a regulating piece 1 extending in the same direction as the connecting pieces 12 on both adjacent sides and having a right-angled shape.
4 are arranged in series, and a mounting piece 15 is arranged in series on the inner corner side of each regulating piece 14 in a horizontal manner.

A gap 16 is formed between the upper and lower regulating pieces 13 and 14, which is approximately the same thickness as the side plate B of the base material A described above.

The present invention has the above-mentioned configuration, and if the hanging fitting 1 is inserted into the groove 10 from below the fixing plate 11 of the connecting fitting 2 and from the connecting piece 4 side and protruding to the upper part of the fixing plate 11, the width of the hanging fitting 1 can be increased from the groove 10. The large locking piece 7 is in contact with the lower surface of the fixed plate 11, the lower end of the cut and raised piece 8 is in contact with the upper surface of the fixed plate 11, and the fixed plate 11 is held between the cut and raised piece 8 and the locking piece 7. The metal fittings 1 and 2 can be connected without falling out of the through groove 10.

In the base material A, the connecting piece 12 of the connecting fitting 2 is fitted into the rectangular frame of the base material A, so that the connecting piece 12 and the upper plate E of the base material A overlap, and both side plates B have regulating pieces 13 and 14. By placing the mounting piece 15 between them and inserting it into the groove formed in the ceiling plate mounting piece C of the base material A, it is possible to attach it to the connecting fitting 2. In this way, each of the connecting fittings 2 By attaching the base material A to the connecting piece 12 and sequentially connecting the base material A at the other end of each base material A connected in four directions using the connecting fittings 2, a large number of squares are formed by the base material A.

If the hanging fixture 1 is connected to a hanging bolt 17 or wire suspended from the roof girder material or the upper floor lower girder material, the base material A forming a large number of squares will be suspended from the ceiling construction area. Thus, ceiling construction is completed by simply placing and supporting the ceiling board on the mounting piece C of the base material A forming each cell.

According to the present invention described above, it is possible to sequentially connect and suspend the standardized ceiling base materials A in a grid pattern, and the hanging fitting 1 is inserted into the groove 10 formed in the fixing plate 11 of the connecting fitting 2. Both metal fittings 1 and 2 are firmly connected by the locking piece 7 and the cut-and-raised piece 8 without any loosening.
