Description

[Detailed description of the invention] The present invention relates to a connection device for connecting two members for ceiling structure in a T-shape.
The longer side piece of is used as the first fitting piece 14, and the shorter side piece is used as the first insertion piece 2, and the first jointer 1
The longer side piece of the second jointer 13 having the same shape and size as 2 is used as the second insertion piece 3, and the shorter side piece is used as the second fitting piece 15, and the fitting part on the side surface of the main bar 1 is used. 11, the first fitting piece 14 of the first jointer 12
and the second fitting piece 15 of the second jointer 13 are fitted, and the first insertion piece 2 and the second insertion piece 3 having different lengths are protruded in parallel from the side surface of the main bar 1, and the vertical piece of the cross bar 4 is fitted. Fitting portions 5 are provided on the upper and lower sides of both ends of the cross bar 4, and the vertical piece 4a of the cross bar 4 is inserted into the first insertion piece and the second insertion piece.
This connection device is inserted between two insertion pieces 3 and the first insertion piece 2 and second insertion piece 3 are fitted into upper and lower fitting parts 5.

Conventionally, one side piece 6a of each of the two symmetrical L-shaped jointers 6 is fitted into the fitting portion 8 of the main bar 7, and the main bar 7 is connected to the two L-shaped jointers 6 at right angles.
Protrude the other side piece 6b of the same length of the two L-shaped jointers 6, insert the other side pieces 6b of the two L-shaped jointers 6 into the fitting parts 10 on both sides of the cross bar 9, and connect the main bar 7 and the cross bar 9. were connected in a T-shape.
However, in such a conventional example, since the other side pieces of the two L-shaped jointers of the same length protrude at right angles to the main bar, when connecting the main bar and the cross bar, the fitting part of the cross bar is The other side pieces of the two L-type jointers must be inserted at the same time, and when attempting to insert the other side piece of one L-type jointer, the other side piece of the other L-type jointer comes off, and the other side piece of the other L-type jointer comes off. When trying to insert the other side piece of the L-type jointer, the other side piece of one jointer came off, and this combined with the poor scaffolding for ceiling construction made it difficult to connect the main bar and crossbar. .

The present invention was made in view of the above-mentioned conventional drawbacks, and its purpose is to first insert only the second insertion piece into the fitting part on one side of the crossbar, thereby holding the crossbar. Then, while holding the crossbar, the first insertion piece can be inserted into the fitting part on the other side of the crossbar independently of the second insertion piece while the crossbar is guided by the second insertion piece. Assembling the bar and crossbar becomes easier, and the construction time can be shortened. Moreover, the first insertion piece and the second insertion piece, which have different lengths, have the same shape and the first jointer of the same size. Second
To provide a connecting device which can be formed using a jointer and can reduce the number of parts.

The present invention will be explained in detail below with reference to the accompanying drawings. The main bar 1 is formed into a substantially T-shape.
Approximately L-shaped fitting portions 11 are formed at the upper and lower portions of both side surfaces of the rising piece 1a. Further, the cross bar 4 is also formed in a substantially inverted T-shape, and substantially L-shaped fitting portions 5 are formed at the upper and lower portions of both sides of the vertical piece 4a of the cross bar 4. Main bar 1 and cross bar 4
The first jointer 12 and the second jointer 13 for connecting are L-shaped plates, and the first jointer 12 and the second jointer 13 have the same shape and the same size. That is, one side piece of the first jointer 12 is the first fitting piece 14, the other side piece of the first jointer 12 is the first insertion piece 2, and one side piece of the second jointer 13 is the second fitting piece. 15, and the other side piece of the second jointer 13 is used as the second insertion piece 3, and as shown in FIG. Length A of insertion piece 3
and the length B of the first insertion piece 2 of the first jointer 12 and the second fitting piece 1 of the second jointer 13.
The length B of 5 is made the same. Cutouts 16 are provided at the upper and lower parts of the proximal end portions of the first insertion piece 2, the second insertion piece 3, the first fitting piece 14, and the second fitting piece 15 for straddling the fitting parts. Thus, the first fitting piece 14 of the first jointer 12 and the second fitting piece 13 of the first jointer 12 are attached to the fitting part 11 of the main bar 1 from the end of the main bar 1.
Insert the second fitting piece 15 to fit the first jointer 12 and second jointer 13 to one side of the main bar 1, and insert the first insertion piece 2 and the second insertion piece 3 at right angles to the main bar 1. protrude in parallel. The main bars 1 are arranged parallel to each other in the ceiling installation space, and then the cross bar 4 is arranged at right angles to the main bar 1, and only the tip of the second insertion piece 3 of the second jointer 13 is placed from the end surface of the cross bar 4. The first jointer 12 is inserted into the fitting groove 5 on one side of the cross bar 4 to hold the cross bar 4, and while the cross bar 4 is held, the second insertion piece 3 guides the cross bar 4 while the first jointer 12 is inserted. Piece 2
The vertical piece 4a of the cross bar 4 is inserted between the first insertion piece 2 and the second insertion piece 3 by inserting the second insertion piece into the other fitting part 5. In this way, the cross bar 4 is horizontally suspended between the main bar 1, and the main bar 1 and the cross bar 4
are arranged in a grid pattern, and the ceiling material is supported by the horizontal piece 1b of the main bar 1 and the horizontal piece 4b of the cross bar 4. In this way, the first insertion piece 2 and the second insertion piece 3 are inserted into the crossbar 4 independently, and the first
When inserting the insertion piece 2, the first insertion piece 2 can be inserted while holding the cross bar 4 by the second insertion piece 3 and guiding the cross bar 4 from the second insertion piece 3, making assembly easy. construction time can be shortened.

As described above, the connecting device of the present invention allows only the second insertion piece to be inserted into the fitting part on one side of the crossbar, thereby holding the crossbar. The first insertion piece can be inserted into the fitting part on the other side of the cross bar independently of the second insertion piece while guiding the bar, and therefore the main bar and cross bar can be assembled and constructed simultaneously. It has the advantage that time can be shortened, and the longer side piece of the L-shaped plate-shaped first jointer is used as the first fitting piece, and the shorter side piece is used as the first insertion piece, The longer side piece of the second jointer, which has the same shape and size as the first jointer, is used as the second insertion piece, and the shorter side piece is used as the second fitting piece. The first fitting piece of the first jointer and the second fitting piece of the second jointer are fitted together, and the first insertion piece and the second insertion piece, which have different lengths, protrude in parallel from the side surface of the main bar. The first insertion piece and the second insertion piece have different lengths.
When protruding the insertion piece, the first and second jointers of the same shape and size can be used, and only one type of jointer is required, and the number of parts can be reduced, and manufacturing, transportation, and It has the advantage of being useful in each process of construction.
