Description

[Detailed Description of the Invention] The present invention relates to a T-bar connection structure.

Conventionally, there are various types of ceiling structures, but for example, a plurality of main T-bars are suspended in parallel below the slab at predetermined intervals using hanging fittings,
A ceiling plate is stretched between adjacent main T-bars so that both ends are placed on the upper surface of the flange of the T-bar, and the side ends of the ceiling plate are placed on the flange of the cross T-bar provided between the T-bars. A construction method is used in which the roof panels are placed in place and the ceiling panels are connected.

By the way, in the above construction method, when connecting the main T-bars to be connected in the longitudinal direction, for example, a rectangular joint fitting with cut and raised pieces provided on the side surface is used.

However, in the above-mentioned conventional joint fittings, the tip of the cut-and-raised piece is bent using an appropriate tool after the cut-and-raised piece of the fitting is inserted into the engagement hole provided in the web of the T-bar. Therefore, the connection work is time-consuming, and since the above-mentioned engagement hole and cut and raised piece are only engaged, there is a drawback that play occurs in the longitudinal direction and horizontal direction of the T-bar at the connection part. .

The present invention was developed in view of the above-mentioned drawbacks of the conventional art, and provides a T-bar connection structure that does not require tools, is easy to connect, and can be firmly connected without play. . Next, the present invention will be explained with reference to the accompanying drawings, which are one embodiment.

Fig. 1 shows the connection structure of the T-bar according to the present invention, in which gripping pieces 3, 3 are cut and raised from the middle part toward both ends on the side surface of the web part 2, and the gripping piece 3 has a tip part of the gripping piece. Locking portions 4 are respectively provided which are cut and raised in opposite directions. In addition, 5
is the flange part.

Reference numeral 6 denotes a T-bar having an inverted T-shape in cross section, and as shown in FIG. 3, a notch 8 is provided at one end of the web portion 7, and a slit-shaped hole 9 is provided near the notch 8. A projection 11 is provided on the upper surface of the flange portion 10 in the longitudinal direction at a predetermined distance from the web portion 7.

Next, a procedure for connecting the T-bars 6, 6 using the connecting fitting 1 having the above configuration will be explained.

First, the web portion 7 of one adjacent T-bar 6 is inserted into the gap between one of the clamping pieces 3 cut and raised in the web portion 2 of the connecting fitting 1 and the web portion 2 . Next, insert the web part 7 of the other T-bar 6 into the gap between the other clamping piece 3 of the connecting fitting 1 and the web part 2,
The end faces of both T-bars 6 are brought together. By the above-mentioned fitting, the web part 7 of the T-bar 6 is clamped by the clamping piece 3 of the connecting fitting 1, as shown in FIG.
The bars 6 are connected, and the locking parts 4 provided on the clamping pieces 3 of the connecting fitting 1 engage with the holes 9 provided in the web part 7 of the T-bar 6, so that the T-bar 6
Prevents it from slipping out or wobbling. This locking portion 4 may be a protrusion that projects inward from the clamping piece. Furthermore, as a result of the above fitting, the flange portion 5 of the connecting fitting 1 is fitted between the web portion 7 of the T-bar 6 and the protrusion 11 provided on the flange portion 10, as shown in FIG. 6 to prevent it from swinging horizontally. In this case, the intermediate portion 1a of the connecting fitting 1 is fitted into the notch 8 provided at the end of the T-bar 6.

In the above embodiment, notches 8 are provided at the ends of adjacent T-bars 6, but the invention is not limited to this. A notch portion into which the intermediate portion 1a of the first portion is inserted may be provided.

As is clear from the above description, according to the present invention, one T-bar of adjacent T-bars is fitted into one clamping piece of the connecting fitting, and the other T-bar is fitted into the other clamping piece of the connecting fitting. Since it can be inserted, there is no need for tools like in the past. T-bars can be easily connected. Furthermore, since the locking portion provided on the clamping piece of the connecting fitting is engaged with the slit-shaped hole provided in the web portion of the T-bar, rattling in the longitudinal direction can be prevented. In addition, by fitting the flange part of the connecting fitting between the web part of the T-bar and the protrusion provided on the flange part, it is possible to prevent the T-bar from swinging laterally, and the T-bar can be firmly connected. can do.
