[Detailed description of the device]

[0001]

[Industrial application] This invention is a structure in which a metal panel made of aluminum, a steel plate, or the like that composes the ceiling of a building, that is, a ceiling panel made of a metal plate is attached to a grid set made of a base material such as a steel rim. In the above, the present invention relates to a structure in which the end portion of the other base material as the crossbar is joined to the side portion of the base material as the main bar constituting the lattice set.

[0002]

2. Description of the Related Art Conventionally, when a ceiling is made up of a ceiling panel made of a metal plate, a grid set is used in which a base material formed of a steel plate is assembled in a grid shape. When constructing this lattice set, it is necessary to join the ends of the short base material as the crossbars to the side portions of the long base material as the main bars. Therefore, conventionally, a specially shaped engaging hole is formed in the side surface of the main bar, and a specially shaped engaging piece provided at the end portion of the crossbar is engaged with the engaging hole, whereby the main bar and the crossbar are engaged. Are joined together.

[0003]

In the above-described conventional method of connecting the base materials, it is necessary to provide a special hole in the main bar on site, so that the connection is extremely troublesome and the rattling is prevented even after the installation. Therefore, there was a problem that it was necessary to insert an iron plate piece to stabilize it.

The object of the present invention is to solve the above-mentioned problems of the conventional connecting structure of the base material, eliminate the troublesome structure such as drilling and inserting the iron plate piece, and make the main bar made of the base material with one touch. The purpose is to provide a structure in which the crossbar and the crossbar can be combined.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an engaging portion having an upwardly U-shaped cross section and elastically bent downward in a corrugated manner from the upper outer side of both sides thereof. When constructing the grid set for mounting the ceiling panel by connecting the base materials that have been installed in a grid pattern, an engaging piece that rises upward is fixed to the end of one base material, and this engaging piece Provided is a structure for connecting a base material for a ceiling panel, which is provided with a protrusion that engages with an engaging recess inside the engaging portion when one piece is pushed between a side portion of the other underlying material and the engaging portion. To do.

[0006]

Since the present invention has the above-mentioned structure, when assembling the grid set for mounting the ceiling panel of the building by assembling the base material in a grid pattern, the engaging piece at the end of the short base material as a crossbar is used. Is pushed between the side part of the long base material as the main bar and the engaging part, the projection of this engaging piece engages with the engaging recess of the engaging part of the main bar to connect the main bar and the cross bar. To do.

[0007]

In the embodiment shown in the drawings, reference numeral 1 is a base material generally called a steel field edge, in which a steel plate is bent in a U-shape with an upward cross section, and the upper portions of both side portions 2 thereof are bent inward in a U-shape. Further, the receiving edge 4 having a double structure is formed by folding back to the outer side, and the extended portion is bent along the outer side of the side portion 2 to form an engaging portion 5, and the lower edge 6 thereof is formed. Is an obliquely outward direction. The inside of the upper portion of the lower edge 6 is used as an engaging recess 7.

As shown in FIG. 2, the base material 1 has a long main bar A, and a plurality of the base materials are arranged in parallel at a predetermined interval and are suspended from the ceiling slab 8 of the building as shown in FIG.

That is, as shown in FIG. 4, a hanger 11 is fixed to the lower end of a hanging bolt 10 suspended from an insert 9 embedded in a slab 8 with a nut.
1. The clip 13 is attached by engaging the bent portion at the upper end of the clip 13 with the base material receiving metal fitting 12 supported at the lower end of the clip 13, and the upward hooks 14 on both sides of the lower end of the clip 13 are engaged with the receiving edges 4 on both sides of the base material 1. To combine.

FIGS. 1 and 2B are crossbars arranged at a constant interval between the main bars A, which have the same structure as the main bar A and are shortened. This crossbar B
1 to 3, the upper U-shaped frame 15 made of a steel plate is firmly attached to the ends of the frame 15 and both upper edges of the frame 15 are crimped into the left and right receiving edges 4, and the bottom of the frame 15 is extended. Then, the engaging piece 16 facing upward is provided on the portion protruding from the end of the base material 1.
Is provided, and the engaging piece 16 is pushed from below between the side portion 2 of the main bar A and the engaging portion 5 to provide the projection 1 provided on the engaging piece 16.
The main bar A and the cross bar B are coupled by engaging the recess 7 of the engaging portion 5 with the main bar A.

Reference numeral 20 denotes a ceiling panel made of a metal plate such as aluminum. A peripheral wall 21 is formed upward on four sides of the ceiling panel, and an upper edge of the peripheral wall 21 is further bent inward to form an inward edge 22.
To form.

A connecting piece 23 made of a steel plate or the like is attached to the inward edge 22. As shown in FIG. 3, the connecting piece 23 is attached by sandwiching the inward edge 22 of the ceiling panel 20 with the laterally U-shaped holding portion 24 provided at the bottom, and the connecting piece 2 facing upwards.
3 is inserted between the side portion 2 of the base material 1 and the engaging portion 5, and the protrusion 25 of the connecting piece 23 is engaged with the recess 7.

Further, as shown in FIG. 5, when the end portion of the crossbar B is obliquely cut, the end portion of the frame 15 is also inclined in the same manner, and the engaging piece 16 is also inclined in the horizontal direction, the main bar is formed. A
Between the side part 2 and the engaging part 5 of the engaging piece 1 which is inclined in the horizontal direction.
When 6 is pushed in, the crossbar 4 is joined to the main bar A in a zigzag shape as shown in FIG.

In this case, the ceiling panel 20 has a triangular shape, and a ceiling excellent in design can be obtained.

[0015]

[Effect] As described above, the present invention provides the main bar forming the lattice set and the cross bar with the engaging portions bent in a corrugated shape on the outer sides of the both sides of the base material having the upward U-shaped cross section which serves as the cross bar. At the end of the base material, an engaging piece that rises upward is provided, and a projection that engages with the engaging recess of the engaging portion is provided on the engaging piece. When the engaging piece at the end portion of the base material that serves as a crossbar when configured is pushed from below between the side portion of the base material that serves as the main bar and the engaging piece, the projection of the engaging piece causes The main bar and the cross bar are coupled by engaging with the engaging recess. Therefore, the assembly of the grid set for mounting the ceiling panel becomes easy and efficient, and the troublesome work of providing a special hole is unnecessary. Further, if the end portion of the crossbar is tilted in the horizontal direction together with the engaging piece, the crossbar can be joined to the main bar in an inclined shape.
