According to the configuration of the present invention, a vertical piece of a butted portion of a pair of ceiling frames is formed by an outer corner connecting tool formed at a right angle and an inner corner connecting tool formed to be more easily elastically deformed than the outer corner connecting tool and formed at an obtuse angle. The ceiling frame is connected by tightening the inner and outer corner connectors with screws in this state.As the screws are screwed, the inner corner connectors are elastically deformed and drawn to the outer corner connectors. At the same time, the area of frictional engagement with the ceiling frame is increased, and the ceiling frames are attracted to each other. Therefore, the gap generated between the ceiling frames can be closed. Further, since the screws are used for tightening the inside and outside corner connecting tools, the tightening can be adjusted according to the width of the gap. Further, even if a gap is generated due to the weight of the lighting fixture or the like after the ceiling frame is installed, the gap can be eliminated by tightening the screw. Furthermore, the height of the outer corner connector is the same as the vertical piece, and it is engaged between the engaging portion of the ceiling frame and the horizontal piece, so there is no displacement in the height direction of the outer corner connector and it is difficult to come off In addition, since the pair of ceiling frames can be connected without alignment, the structure is simplified. Furthermore, in the event of an earthquake or the like, the ceiling frame can slide with respect to the inner and outer corner connectors, so the inner and outer corner connectors are not deformed, and tighten the screws after the earthquake has disappeared. The original tightened state can be obtained.

〔Example〕

One embodiment of the present invention will be described with reference to FIGS.

The ceiling frame 1 has a horizontal piece 1a and a vertical piece, as shown in FIG.
1b is formed in an inverted T shape, and a vertical pipe 1b is provided with a square pipe-shaped engaging portion 1c at the tip thereof. As shown in FIG. 4, the distal end of the ceiling frame 1 has a notch 1d for screw insertion formed by cutting the vertical piece 1b and the engaging portion 1c, and when the pair of ceiling frames 1 In addition, a gap can be formed. Further, the tip of the horizontal piece 1a is cut at 45 ° so that no gap is formed when the pair of ceiling frames 1 are put together. As shown in FIG. 1, the ceiling frame 1 is formed in a grid, and a ceiling material 2 and a lighting fixture 3 are installed inside the grid. A ceiling is formed by connecting a large number of grids. When the grids are connected in series, spacers 4 are installed in gaps generated between adjacent grids. A hanger 5 is fixed to the spacer 4, and a hanging bolt 6 is connected to the hanger 5 so that the grid is hung on an upper floor (not shown).

As shown in FIG. 5, each of the corner connectors 7 and 8 comprises a substantially L-shaped inner corner connector 7 and an outer corner connector 8. FIG. 6 is a perspective view of the corner connectors 7, 8 of FIG. 5 as viewed from the opposite side.

The inner corner connecting tool 7 is formed to be lower in height than the outer corner connecting tool 8, so that it is more easily elastically deformed than the outer corner connecting tool 8. To make it easier to deform,
The plate thickness may be reduced. As shown in FIG. 7, the inner corner connector 7 is formed such that a pair of flanges are opened at an obtuse angle (for example, 95 °) when not tightened with a screw. The butting portion of the pair of flanges is formed so as to be perpendicular to the joining line generated at the butting portion of the ceiling frame 1. In this portion, a screw insertion hole 7a for inserting the screw 9 is formed.

The outer corner connector 8 is formed in an L-shaped cross section, and is formed in accordance with the height of the vertical piece 1b of the ceiling frame 1. The corners of the pair of flanges of the outer corner connecting tool 8 are formed so as to be pressed inward to be perpendicular to the joining line of the butt portion of the ceiling frame 1. In this portion, a screw hole 8a communicating with the screw insertion hole 7a of the inner corner connecting tool 7 is formed.

An installation procedure of the ceiling frame 1 according to this embodiment will be described. A pair of ceiling frames 1 each having the tip of the horizontal piece 1a cut at 45 ° are placed facing each other. Each vertical piece of a pair of ceiling frames 1
The outer corner connector 8 is brought into contact with 1b. The inner corner connector 7 is installed inside the vertical piece 1b. A screw 9 is inserted from the screw insertion hole 7a of the inner corner connector 7 and the outer corner connector 8
Screw hole 8a. As the screwing proceeds, the inner corner connector 7 is drawn toward the outer corner connector 8. At this time, the inner corner connecting tool 7 bends at a right angle, draws the vertical piece 1b of the ceiling frame 1, and closes the gap between the butted portions of the ceiling frame 1. The screw 9 is stopped when the gap is closed. Thus, the installation of the ceiling frame 1 is completed.

According to the configuration of this embodiment, the pair of ceiling frames 1 is formed by the outer corner connecting tool 8 formed at a right angle and the inner corner connecting tool 7 formed to be more elastically deformable than the outer corner connecting tool 8 and formed at an obtuse angle. The ceiling frame 1 is connected by sandwiching the vertical piece 1b of the abutting portion and tightening the inner and outer corner connectors 7, 8 with the screws 9 in this state. 7 is elastically deformed and drawn to the outer corner connecting tool 8, and at the same time, the area of frictional engagement with the ceiling frame 1 increases, and the ceiling frame 1 is drawn toward each other. Therefore, the gap generated between the ceiling frames 1 can be closed. In addition, since the screws 9 are used for tightening the inner and outer corner connectors 7, 8, the tightening can be adjusted according to the width of the gap. After the ceiling frame 1 is installed, the lighting fixture 3
Even if a gap occurs due to such weight, the gap can be eliminated by tightening the screw 9. Further, the height of the outer corner connector 8 is the same as that of the vertical piece 1b and is engaged between the engaging portion 1c of the ceiling frame 1 and the horizontal piece 1a. The ceiling frame 1 can be connected without any alignment, and the structure can be simplified. Further, in the event of an earthquake or the like, the ceiling frame 1 can slide with respect to the inner and outer corner connectors 7, 8, so that the inner and outer corner connectors 7, 8 can be slid.
The screw is not deformed, and after the earthquake or the like disappears, the screw can be re-tightened to the original tightened state.

[Effect of the invention]

According to the connecting structure of the ceiling frame of the present invention, a pair of ceiling frames is formed by an outer corner connecting tool formed at a right angle and an inner corner connecting tool formed at an obtuse angle that is more easily elastically deformed than the outer corner connecting tool. The vertical frame of the butted part is sandwiched, and the ceiling frame is connected by screwing the inner and outer corner connectors with screws in this state.As the screws are screwed, the inner corner connectors elastically deform and the outer corners are deformed. At the same time that the ceiling frame is attracted to the connector, the area of frictional engagement with the ceiling frame increases, and the ceiling frames are attracted to each other. Therefore, the gap generated between the ceiling frames can be closed. Further, since the screws are used for tightening the inside and outside corner connecting tools, the tightening can be adjusted according to the width of the gap. Further, even if a gap is generated due to the weight of the lighting fixture or the like after the ceiling frame is installed, the gap can be eliminated by tightening the screw. Furthermore, the height of the outer corner connector is the same as the vertical piece, and it is engaged between the engaging portion of the ceiling frame and the horizontal piece, so there is no displacement in the height direction of the outer corner connector and it is difficult to come off In addition, since the pair of ceiling frames can be connected without alignment, the structure is simplified. Furthermore, in the event of an earthquake or the like, the ceiling frame can slide with respect to the inner and outer corner connectors, so the inner and outer corner connectors are not deformed, and tighten the screws after the earthquake has disappeared. The original tightened state can be obtained.
