Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method of reinforcing a ceiling opening which is opened as a lighting fixture or a duct outlet.

[0002]

2. Description of the Related Art Conventionally, in order to reinforce an opening of a ceiling that has been opened as an opening of a lighting fixture or a duct, a field edge cut for the opening is connected with another field edge or a field edge receiver, The opening is reinforced. At this time, the field edge material and field edge receiving material used as a reinforcing material are arranged along the periphery of the opening,
Alternatively, a method of arranging above the opening and welding to another adjacent field edge or field edge receiver has been adopted.

[0003]

However, according to such a conventional reinforcing method, since the reinforcing material is welded around and above the opening, it is necessary to perform this reinforcing work before mounting the ceiling board. Therefore, first, the marking on the field edge or the field edge receiver is cut and then cut, the reinforcing material is welded and reinforced, and then the ceiling board is mounted. Further, a series of operations such as marking out the opening on the ceiling and cutting the opening again requires a great deal of time and labor, which is inefficient.

Therefore, the present invention was created in order to solve the above problems, and an object thereof is to provide a method of reinforcing an opening of a ceiling base, which can simplify the work of reinforcing the opening of the ceiling. Is.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention relates to a hanging bolt P via a field edge receiver Q to a field edge S.
A method of reinforcing an opening portion of a ceiling base material by suspending a ceiling board R, comprising: a board opening step of forming a predetermined opening portion R1 in the ceiling board R; and a ceiling base material field along the opening portion R1 of the mounted ceiling board R. For the purpose of solving the problem, it is composed of a base material cutting step of cutting the edge S and the field rim receiver Q and a connecting step of connecting the end portion of the cut ceiling base material to the suspension bolt P by the suspending wire T. Use it as a means.

[0006]

That is, according to the present invention, the end portion of the ceiling substrate located in the opening of the ceiling substrate is connected to the suspension bolt P via the suspending wire T and is reinforced. At this time, the opening reinforcement work is performed as a post-work after the mounting of the ceiling board R.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings. The working process of the present invention includes a board opening process (see FIG. 1), a base material cutting process (see FIG. 2), and a connecting process (see FIG. 3).

In the board opening step (see FIG. 1), the ceiling board R is marked out and a predetermined opening R1 is formed. The opening operation of the ceiling board R may be performed either after the ceiling board R is attached to the ceiling substrate formed of the field edge S or the field edge receiver Q, or before the ceiling board R is attached. And
After mounting the ceiling board R on the ceiling substrate, the process proceeds to the next substrate material cutting step.

In the step of cutting the base material (see FIG. 2), the ceiling edge field S along the opening R1 of the mounted ceiling board R is cut.
And cut off the field Q. At this time, the worker cuts the base material exposed from the opening R1 of the ceiling board R, and the opening R1 of the ceiling board R does not need to be stamped on the base material conventionally.

The connecting step (see FIG. 3) is a step of connecting the ends of the cut ceiling base material to the suspension bolts P with the suspension wires T. Hanging wire T used at this time
Is equipped with a connecting metal fitting 1 connected to the hanging bolt P and a fixing metal fitting 2 connected to the ceiling substrate at both ends of the suspension wire T, respectively, to facilitate the connection work of the suspension wire T.

The connecting metal fitting 1 is connected to the side surface of the hanging bolt P by utilizing the elastic force of the metal fitting. In the illustrated example, both end portions of the connecting plate 1A bent in a substantially V shape on the side surface are formed on the side surface. A notch 1B for engaging with the hanging bolt P is provided, a connecting arm 1C is swingably connected to the central portion of the connecting plate 1A, and an end portion of the suspension wire T is connected to the connecting arm 1C. (See Figure 4). At this time, the hanging bolt P may be any type of hanging bolt P such as a type in which both ends of the bolt are threaded or a type in which the entire bolt is threaded.

The fixing metal fitting 2 is particularly designed to be connected to the field support Q (see FIG. 5). That is, the connecting arm 2B for connecting the suspending wire T is screwed to the substantially C-shaped fixture 2A mounted on the side surface of the field rim receiver Q. Then, the wire pulling metal fitting 2C is connected to the end portion of the connecting arm 2B to adjust the length of the suspending wire T.

FIG. 6 shows an example of the use of the opening reinforced by the present invention, in which a lighting fixture is arranged.

[0014]

The present invention achieves the original object by being configured as described above. That is, it is a method of reinforcing the opening portion of the ceiling base material by suspending the field edge S on the suspension bolt P via the field edge receiver Q, and a predetermined opening portion R1 on the ceiling board R.
Board opening process to pierce and the mounted ceiling board R
Of the ceiling base material along the opening R1 of the ceiling base material cutting step for cutting the field edge S and the field edge receiver Q, and the connection of connecting the ends of the cut ceiling base material to the suspension bolts P with the suspending wires T. Depending on the process, the opening of the ceiling base can be reinforced, so that the opening can be reinforced in a later process after mounting the ceiling board R.

As a result, it is possible to omit the work of marking out the ceiling substrate and the welding work of the reinforcing material to the ceiling substrate, which have been required until now, and the reinforcing work can be extremely simplified. Is.

As described above, according to the present invention, various industrially beneficial effects can be obtained such that the work of reinforcing the opening of the ceiling can be simplified.
