DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a reinforcing structure for a steel ceiling.

[0002]

2. Description of the Related Art A steel ceiling constructed by attaching a ceiling material to a lower surface of a steel bezel assembled in an upper part of a room is, for example, when arranging lighting equipment on the ceiling material, the ceiling material must be reinforced. No.

[0003] In a structure for reinforcing a ceiling material in which lighting equipment is arranged, a reinforcing plate is usually placed on the back surface of the ceiling material.

[0004]

However, if the field edge is a wooden member, the field edge and the reinforcing plate can be connected to each other by a fastening means such as nailing, so that the reinforcement can be easily performed.
When a steel ridge is used as described above, it is difficult to easily connect the reinforcing plate and the steel ridge.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to make it possible to easily perform a connection operation between a reinforcing plate for reinforcing a ceiling material and a steel rim, thereby improving the reinforcement. It is an object of the present invention to provide a steel ceiling reinforcement structure capable of performing construction work efficiently.

[0006]

In order to solve the above-mentioned problems, a reinforcing structure for a steel ceiling according to the present invention comprises a steel ceiling formed by attaching a ceiling material to a lower surface of a steel ridge formed in an upper part of a room. When arranging the lighting equipment, decorative pillars, partition walls, etc., it is a structure to reinforce the ceiling material for arranging the equipment, and the reinforcing material is supported by the adjacently disposed steel field edge to which the ceiling material to which the equipment is to be attached is attached. The members are connected to each other, a reinforcing plate is superimposed on the back surface of the ceiling material, and an end of the reinforcing plate is supported by the reinforcing support member, and the ceiling material and the reinforcing plate are integrated by a screw member. I made it.

According to the present invention, a ceiling material on which various equipment such as a decorative column, a partition wall, and lighting to be installed in a room is disposed by a reinforcing plate supported on a steel bezel via a reinforcing support member. Because it is reinforced, the ceiling material is surely reinforced even when installing heavy equipment.

The steel bezel is made of a lip grooved steel with an opening between lip pieces facing upward, and the reinforcing support member is fitted into the opening of the steel bezel from above. A fitting portion that fits in may be provided, and the reinforcing support member may be pushed into the steel bezel from above, and the fitting portion may be fitted and connected to the opening.

By doing so, the opening of the steel field edge is
The reinforcing support member can be connected to the steel bezel by a simple operation of fitting the fitting portion of the reinforcing support member from above.

A lower plate receiving portion for receiving the reinforcing support member from an underside of an end of the reinforcing plate;
A member having a plate upper receiving portion that is located above the plate lower receiving portion by the thickness of the reinforcing plate and abuts on the upper surface of the reinforcing plate may be used.

With this configuration, the reinforcing support member holds the ends of the reinforcing plate from above and below by the plate lower receiving portion and the plate upper receiving portion, so that the reinforcing plate can be reliably lifted when the screw member is driven. Can be prevented.

The reinforcing support member is formed by bending a metal plate to form the plate-shaped fitting portion, the plate-shaped lower plate receiving portion, and the plate-shaped upper plate receiving portion. You may.

With this configuration, a lightweight and low-cost reinforcing support member can be provided.

[0014] Further, the adjacent steel bezel to which the ceiling material on which the equipment is to be placed is attached may be constituted by at least two steel bezels arranged in parallel with each other.

[0015] In this case, since many steel ridges support the ceiling material on which the equipment is to be disposed, a more robust structure for reinforcing the ceiling material is obtained.

The hole provided in the center of the reinforcing plate 8 is a hole 8a for lighting wiring.

Then, the screw member 10 is driven into the overlapping gypsum board 4 and the reinforcing plate 8 from below to integrate the gypsum board 4 and the reinforcing plate 8.

According to the reinforcing structure for lighting a steel ceiling, the gypsum board 4 on which the lighting equipment is to be placed is supported by the steel ridges 2A and 2B via the reinforcing support members 6 and the reinforcing plate 8 is provided. Therefore, the gypsum board 4 can be reliably reinforced even when a large-weight lighting facility is installed.

Further, the openings 2c of the steel ridges 2A and 2B are provided.
In addition, the reinforcing support member 6 can be connected to the steel ridges 2A and 2B by a simple work of fitting the fitting portion 6a of the reinforcing support member 6 from above, so that the efficiency of the reinforcing work is improved. be able to.

The reinforcing support member 6 is formed by a plate lower receiving portion 6b and a plate upper receiving portion 6c.
Of the reinforcing plate 8 when driving the screw member 10 can be reliably prevented.

Further, the reinforcing support member 6 forms the fitting portion 6a, the plate lower receiving portion 6b, and the plate upper receiving portion 6c by bending a metal plate.
A lightweight and low-cost member can be provided.

Next, FIG. 2 shows a steel ceiling lighting reinforcement structure according to a second embodiment. Note that the same components as those of the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. Further, reference numeral 1 in FIG.
