Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ceiling device, and more particularly to a connecting structure of a main T-bar on which a ceiling plate is mounted and a cross T-bar.

[Conventional technology]

A conventional typical structure for connecting the main T-bar and the cross T-bar in a mutually orthogonal state is shown in Japanese Patent Publication No. 62-31133 "Ceiling Device".

As shown in FIG. 2, the locking parts 101 and 102 are cut and raised so as to form a pair of upper and lower parts on the vertical plate part of the main T-bar 1, and the locking parts 101 and 102 and the vertical plate part are connected to each other. The main T-bar 1 and the cross T-bar 2 are in an orthogonal state by inserting and engaging the locking tongue piece 103 provided in the end portion of the cross T-bar 2 in the direction orthogonal to the longitudinal direction in the clearance between them. It is a structure that connects to.

By the way, in FIG. 2, reference numerals 13 and 23 denote horizontal edges of the main T-bar 1 and the cross T-bar 2, respectively, and a groove formed in the end face of the ceiling plate (not shown) is fitted and supported therein. It is like this.

[Problems to be solved by the device]

The other end (not shown) of the cross T-bar 2 is also the main T-bar 1.
However, the insertion engagement is the same as that shown in the figure. Therefore, when the main T-bar 1 and the cross T-bar 2 are not correctly arranged in the orthogonal state, the main T-bar 1
It is difficult to insert the locking tongue 103 into the clearance between the locking portions 101 and 102 of the vertical plate and the vertical plate portion, and particularly when the length of the locking tongue 103 is increased to increase the strength of the connection, this assembly There is a serious drawback that the difficulty of work doubles.

Further, in this conventional technique, the cross T-bar 2 is the locking tongue piece 10.
In the extreme case, there is a risk of disconnection from the main T-bar 1 because there is no means to prevent the 3 from moving in the direction of slipping out.

[Means for Solving the Problems]

The present invention has been made to solve the above-mentioned problems, and a wall surface of a vertical plate portion is formed by cutting and raising a wall parallel to the vertical plate portion, and is fitted above the locking wall. A main T-bar having a hole formed therein and a lateral deviation preventing piece which is projected at the end portion in the longitudinal direction and should be fitted into the fitting hole are formed, and the lateral deviation preventing piece extends below the lateral deviation preventing piece in a direction orthogonal to the lateral deviation preventing piece. A cross T-bar formed with a lock plate to be engaged between the lock wall and the vertical plate portion, wherein the lock plate of the cross T-bar is perpendicular to the lock wall of the main T-bar. The ceiling is characterized in that, when it is inserted into a clearance between the plate portion and the plate portion from above, the lateral deviation prevention piece is fitted in the fitting hole and both the main T-bar and the cross T-bar are connected in an orthogonal state. It is a device.

[Action]

The locking plate of the cross T-bar is sandwiched between the vertical plate portion of the main T-bar and the engaging wall, and the movement of the cross T-bar in the longitudinal direction is completely locked.

At the same time, the lateral shift preventing piece of the cross T-bar fits into the fitting hole of the main T-bar, and the cross-T bar is completely prevented from moving in the longitudinal direction.

〔Example〕

FIG. 1 shows an embodiment of the present invention with a main T bar and a cross T
It is a perspective view showing the bar in a separated state, and this embodiment will be described with reference to this figure.

An engaging wall 11 is formed at the connecting portion of the vertical plate portion of the main T-bar 1 so as to be parallel to the vertical plate portion and cut and raised so as to define a gap of an appropriate size therebetween.

Thus, the upper edge of the engagement wall 11 is formed as an insertion guide portion 11A that is bent outward.

Further, a fitting hole 12 having a width which will be described later in the longitudinal direction of the main T-bar 1 is formed above the engagement wall 11.

The fitting hole 12 is a hole that is cut upward in a slot shape from the hole in which the engagement wall 11 is cut and raised, and both corners of the lower part thereof have a shape that is slightly turned up from the position of the broken line as shown in an enlarged manner. It is formed as a locking lock portion 12A. That is, it should be noted that the locking lock portion 12A projects slightly outward from the vertical plate surface of the main T-bar 1.

A lateral deviation preventing piece 22 is provided at an end portion in the longitudinal direction of the cross T-bar 2 so as to protrude by an appropriate length, and a locking plate 21 extending in a direction orthogonal to the lateral deviation preventing piece 22 is provided below the lateral deviation preventing piece 22.

The extending length of the locking plate 21 is the width of the engaging wall 11 (main T
The length is preferably substantially equal to the length of the bar 1 in the longitudinal direction), and the upper corners of the lateral deviation prevention pieces 22 are formed as fitting rounded portions 22A having an appropriate radius.

The clearance between the engagement wall 11 of the main T-bar 1 and the vertical plate portion and the width of the fitting hole 12 are preferably slightly larger than the plate thicknesses of the locking plate 21 and the lateral deviation prevention piece 22 described above, respectively.

To connect the cross T-bar 2 to the main T-bar 1 described above, the locking plate 21 of the cross T-bar 2 is aligned with the clearance between the engagement wall 11 of the main T-bar 1 and the vertical plate portion, It may be pushed downward in the direction of arrow P in the figure.

By doing this, the locking plate 21 is guided by the insertion guide portion 11A and fits into the clearance behind the locking wall 11, and at the same time, the lateral slip prevention piece 22 is fitted into the fitting hole 12 so as to slide from the upper edge thereof. Marry. Of course, the lateral shift prevention piece 22 needs to have an appropriate length to facilitate this fitting, and the fitting rounded portion 22A
Also helps this insertion.

However, in the case of connection fitting, the locking lock portion 12A already described
Presses against the side surface of the locking plate 21, and when the fitting operation is completed, a clicking sound is emitted to notify the fitting to the correct position and prevent the upward escape.

[Effect of device]

According to this invention, the movement of the cross T-bar in the longitudinal direction is caused by the engagement between the engagement wall and the locking plate, and the left and right along the longitudinal direction of the main T-bar are caused by the engagement between the lateral deviation prevention piece and the fitting hole. Since all movements are securely locked, the main T
This has the effect of ensuring a reliable connection between the bar and the cross T bar. Further, it is an assembling method in which the locking plate of the cross T-bar is pushed into the clearance behind the locking wall of the main T-bar from above. At the time of assembling, the cross-T bar is pushed slightly tilted so that the assembling operation is easy. is there. Further, if it is limited to the embodiment, there is an effect that the locking lock portion can prevent the situation of falling out of the assembled and connected state.
