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.

In this invention, base materials of standardized lengths as described above are sequentially connected in four directions to form a large number of squares with the base materials on the ceiling construction surface, and the ceiling board is placed within these squares and suspended. It provides metal fittings to hold the parts.

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 bored.

A locking piece 6 having a length larger than the width of the metal plate 3 is continuously provided at the lower part of the metal plate 3, and locking grooves 7 are formed on both sides between the metal plate 3 and the locking piece 6.

The connecting fitting 2 is centered around a horizontally installed fixing plate 9, which has a semicircular or right-angled depression 8 in a square part of a rectangular plate.
Connecting pieces 10 are horizontally extended outward on the four sides of the fixing plate 9, and regulating pieces 11 are bent downward and connected at right angles on both sides of the protruding direction of each connecting piece 10.

At the bottom of each section 8 of the fixing plate 9, there is a regulating piece 12 extending in the same direction as the connecting pieces 10 on both adjacent sides and having a right-angled shape.
are arranged in series, and a mounting piece 1 is placed horizontally on the inner corner side of each regulating piece 12.
Set up 3 in a row.

A gap 14 is formed between the upper and lower regulating pieces 11 and 12, and the gap 14 is approximately the same thickness as the side plate B of the base material A mentioned above. A through groove 15 having the same length as that of the locking groove 7 provided in the metal plate 3 is provided on both sides of the through groove 15, which has a circular recess approximately the same width as the width between the locking grooves 7 on both sides of the center part. Within this range, inclined cut-and-raised pieces 16 whose tips are located at the uppermost position are provided to protrude on the fixing plate 9 in opposite directions.

The present invention has the above configuration, and the hanging fitting 1 and the connecting fitting 2 are as follows:
A groove 15 in which the locking piece 6 at the lower part of the hanging fixture 1 is formed in the fixing plate 9
If the hanging bracket 1 is inserted into the lower surface of the fixing plate 9 from above and rotated along the slope of the cut and raised pieces 16 protruding from the fixed plate 9, each cut and raised piece 16 will fit into the locking grooves on both sides of the metal plate 3. 7, in contact with the lower end of the metal plate 3, fixing the hanging bracket 1 by the elasticity of the metal plate,
It becomes possible to connect and fix both.

In the base material A, the connecting piece 10 of the connecting fitting 2 is fitted into the rectangular frame of the base material A, so that the connecting piece 10 overlaps with the upper plate E of the base material A, and both side plates B are placed between the regulating pieces 11 and 12. It can be attached to the connecting fitting 2 by placing the mounting piece 13 in the groove formed in the ceiling plate placing piece C of the base material A, and in this way, each connection of the connecting fitting 2 can be attached. By attaching the base material A to the piece 10 and sequentially connecting the base materials 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 the hanging bolt 17 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, 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 material A in a grid pattern, and the hanging fitting 1 and the connecting fitting 2 are loosened by the slanted cut and raised pieces 16. It is firmly connected without causing any problems.
