Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a ceiling material positioning device.

[Background technology]

As shown in Fig. 1, in order to attach the ceiling material 1, a T-bar 3 assembled in a lattice shape with hanging fittings 2 is suspended from the slab of the building frame to form a ceiling material support frame 4 with an inverted T-shaped cross section. Conventionally, a construction method in which the ceiling material 1 is dropped into the support frame 4 has been widely adopted.

At this time, in order to prevent the ceiling material 1 dropped into the support frame 4 from floating up, a floating prevention device 5 as shown in FIG. 2 is attached to the T-bar 3. As shown in FIG. 3, this lifting prevention device 5 is bent into a U-shape so as to fit over the head 3a of the T-bar 3, and has cut and raised pieces on both sides 5a to prevent it from coming off. 6
is provided inward and fixed to the head of the T-bar 3, and the lower ends of both side pieces 5a are bent into an L shape, and the end edges of the ceiling material 1, which is fixed on the support piece 3b of the T-bar 3, are attached upward. The ceiling material 1 was held down from above to prevent it from floating up.

However, such floating preventer 5 could not prevent the ceiling material 1 from sliding on the support piece 3b (in the direction of the arrow shown in FIG. 3). In addition, the lower end of the anti-float device 5 is outwardly L.
Since the ceiling material 1 is bent into a shape, when constructing the ceiling material 1, as shown in FIG. Next, it is necessary to attach the floating prevention device 5 to the T-bar 3, but it is necessary to attach the anti-floating device 5 to the T-bar 3.
When the ceiling material 1 is already installed on the surface and the C surface, there is a problem in that it is difficult to install the floating preventive device 5 because it has to be installed from the D surface which is far from the installation place.

[Purpose of invention]

The object of this invention is to provide a ceiling positioning device that can prevent ceiling materials from floating and shifting.

[Disclosure of invention]

The ceiling material positioning device of this invention is bent into a substantially U-shape and is fitted and fixed to a rising piece of a ceiling material support frame having an inverted T-shaped cross section, and the ceiling material that has been dropped into the support frame is attached to a side piece. A protrusion for preventing floating is provided, and a hanging piece for ceiling positioning is provided hanging from the protrusion, and a hanging piece for ceiling positioning is provided at one end of the upper part of the protrusion for preventing floating, and the lower part is provided at a right angle to the side piece. A plate-shaped body is provided as a hanging piece for positioning the material.

An embodiment of this invention will be described with reference to FIGS. 5 to 10. That is, as shown in FIG. 5, this ceiling material positioning device includes a main body 8 which is bent into a substantially U-shape and has protrusions 7 on both sides, and a T-shape extending from one end of the main body 8 to both sides. It is provided with an elongated main body 8 and a plate-shaped body 9 having approximately the same height.

Inwardly bent cut-and-raised pieces 10 are provided on both sides of the main body 8, and when the main body 8 is fitted onto the T-bar 3, the T-bar head is formed as shown in FIG. The main body 8 engages with the lower groove 11 of the
This prevents the main body 8 from floating up and fixes the main body 8 to the T-bar 3. Further, the projections 7 provided on both sides of the main body 8 have sloped upper portions so that the side pieces of the main body 8 will bend when the ceiling material 1 is lowered and will not hinder the lowering of the ceiling material 1. . The hanging piece 12 at the bottom of the projection 7 comes into contact with the side rising portion 1a of the ceiling material 1.

This positioning device 13 has T as shown in FIG.
It is attached to a corner portion of a ceiling material support frame 4 framed with bars 3. Installation is on one of the corner T-bars 3
This is done by fitting the main body 8 onto the rising piece. In this way, the adjacent ceiling material support frame 4
A main body 8 and a plate-like body 9 are arranged at each corner of the
As a result, it is possible to provide a wall portion that prevents the ceiling material 1 from slipping or shifting in both the vertical and horizontal directions.

Next, the operation of this embodiment will be explained with reference to FIGS. 8 and 9. As shown in FIGS. 8 and 9, when the ceiling material 1 is installed, the rising portion of the ceiling material 1 is controlled by the hanging piece 12 of the main body 8 and the hanging piece 14 for positioning the ceiling material at the lower part of the plate-like body 9. The outer surface is pressed down in the vertical and horizontal directions to prevent the ceiling material 1 from shifting. Further, the projection 7 of the main body 8 presses the upper end of the rising portion 1a of the ceiling material 1 to prevent the ceiling material 1 from floating up.

Since the protrusion 7 is formed in a sloped shape as described above, the positioning device 13 is fitted to the corner of the ceiling material support frame 4 in advance as shown in FIG. 7, and then the ceiling material 1 is dropped. I can do it.

As shown in FIG. 10, the positioning device 13 is attached to two diagonally opposite corners of the ceiling material support frame 4. In this way, the main body 8 and the plate-shaped body 9 can prevent the ceiling material 1 from shifting in the vertical and horizontal directions. Furthermore, as shown in FIG. 10, one positioning device 13 can prevent two adjacent ceiling materials 1 from shifting and floating, so one positioning device 13 is required for each ceiling material. Economical.

In addition, as shown in FIG. 11, by providing a projection 7' on the plate-shaped body 9' as well, it is possible to more safely prevent the ceiling material 1 from rising. Furthermore, in FIG. 12, the main bodies 8 and 8' are connected orthogonally to each other, and this also has the same effect as the previous embodiment.

[Effect of idea]

According to this invention, it is possible to reliably prevent the ceiling material from floating and shifting in the horizontal and vertical directions.
