Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a structure in which a metal panel made of aluminum, a steel plate, or the like, which constitutes the ceiling of a building, that is, a panel made of a metal plate is attached to a grid set made of a base material such as a steel rim.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, when a ceiling is formed by a ceiling panel formed of a metal plate, a grid set in which a base material formed of a steel plate is assembled in a grid shape is used. To attach the panel to this grid set, screw holes are provided in the base material that composes the grid set, holes are provided in the panel to insert screws, and the screws passed through these holes are used in the screw holes of the base material. It is screwed in and fixed.

[0003]

[Problems to be solved by the device]

 The conventional panel mounting method as described above requires a great deal of labor for mounting, and the head of the screw is exposed even after mounting, so that the appearance is not good. For this reason, there was a problem in that it was necessary to attach a blind cover plate to cover the screws after mounting.

An object of the present invention is to solve the problems of the above-described conventional ceiling panel mounting structure, and to provide a structure in which the ceiling panel can be mounted by one-touch without a troublesome structure such as screwing. Is to provide.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a base material provided with an elastic engaging portion bent downward from the upper outside of both side portions in an upward U-shaped cross section, and an upward facing peripheral portion. A ceiling panel provided with a peripheral wall and fixed to the peripheral wall of the ceiling panel, and when pushed between the side portion of the base material and the engaging portion, engages with an engaging recess inside the engaging portion. Provided is a ceiling panel mounting structure including a connecting piece provided with a protrusion.

[0006]

[Action]

 Since the present invention has the above-mentioned configuration, when mounting the ceiling panel to the lattice set in which the base material is assembled in a lattice shape and suspended from the ceiling slub of the building, an appropriate position of the inward edge of the upper part of the peripheral wall of the ceiling panel is used. A plurality of connecting pieces are arranged around the ceiling panel by means such as engaging the clasps of the connecting pieces with each other. Then, when the connecting piece around the ceiling panel is pushed between the side portion of each base material and the engaging portion, the projection of each connecting piece engages with the recess of the engaging portion to form the ceiling panel into a lattice set. To fix.

[0007]

【Example】

 In the embodiment shown in the drawings, 1 is a base material generally called a steel field edge, which is formed by bending a steel plate into a U-shape with a horizontal cross section, and bending the upper portions of both side portions 2 into an inward U-shape, and further outward. The receiving edge 4 having a double structure is folded back to form an engaging portion 5 by bending the extended portion along the outside of the side portion 2 into a corrugated shape, and the lower edge 6 thereof is obliquely outside. It is oriented. 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 base materials A are arranged in parallel at a predetermined interval and are suspended from a ceiling slab 8 of a building as shown in FIG.

That is, as shown in FIG. 3, 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, and a base material receiving metal fitting 12 supported by the lower end of the hanger 11 is supported. The clip 13 is attached by engaging the bent portion of the upper 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.

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. The connecting means between the crossbar B and the main bar A is free, but in the embodiment, as shown in FIG. 4, the engaging piece 15 is projected upward from the lower part of the end of the crossbar B, and the engaging piece 15 is formed. Is pressed from below between the side portion 2 of the main bar A and the engaging portion 5, and the projection 16 provided on the engaging piece 15 is engaged with the recess 7 of the engaging portion 5 to join them.

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 thereof, and an upper edge of the peripheral wall 21 is further bent inward to form an inward edge 22.

A connecting piece 23 made of a steel plate or the like is attached to the inward edge 22. As shown in FIG. 3, this 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 upward connecting piece 23 is attached to the side portion 2 of the base material 1. And the engaging portion 5, the projection 25 of the connecting piece 23 is engaged with the recess 7.

[0013]

【effect】

 In this invention, as described above, since the wavy bent engaging portions are provided on the outer sides of both sides of the base material of the upward U-shaped cross section which constitutes the lattice set, the structure of the base material is different from that of the base material. By pushing the connecting piece fixed to the peripheral wall of the ceiling panel from below between the side part of the base material and the engaging piece, the projection of the connecting piece engages with the recess of the engaging portion, and with one touch. Ceiling panel is installed. Therefore, the mounting of the ceiling panel becomes easy and efficient, and since the screw is not required for mounting the ceiling panel, there is an effect that a troublesome work for hardening the screw is also unnecessary.
