Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint covering device for covering joints of ceilings or side portions of right and left buildings separated by joints.

[0002]

2. Description of the Related Art Conventionally, this type of joint cover device is mounted on the left and right buildings by a plurality of mounting brackets for urging the joint cover so that the two rule parts always contact the ceiling portions of the right and left buildings.

[0003]

In the conventional joint cover device, when the right and left buildings sway due to an earthquake or the like, the joint cover device can move following the swaying motion of the joint in the width direction and the vertical direction. When the left and right buildings swing in the front-rear direction, the joint cover is damaged or a gap is formed between the joint and the side wall.

The present invention has been made in view of the above-mentioned conventional drawbacks,
Even if the left and right buildings swing in the vertical direction, the front and rear, and the left and right directions due to an earthquake or the like, the joint cover follows and moves, and the joint cover device can efficiently prevent a gap from being formed at an end of the joint cover. It is intended to provide.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a ceiling joint cover for covering the joints of the ceiling portions of the left and right buildings separated from each other by a joint, and both of the ceiling joint covers. A plurality of ceiling joint cover mounting brackets to be attached to the left and right buildings in a state where the rule parts are constantly urged to contact the ceiling portions of the left and right buildings, and project outward at least at one end of the ceiling joint cover. End cover composed of two slide plates respectively slidably attached to the end cover and two or more slide plates for urging the two slide plates of the end cover so as to always project outward. The joint cover device is constituted by the tension spring.

[0006]

The joint cover device constructed as described above is mounted on the ceiling joint cover so that the end covers always project outward when the left and right buildings swing due to an earthquake or the like. The cover moves with no gap between the cover and the wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 9, reference numeral 1 denotes a joint cover of the present invention which covers a joint 2 a of a ceiling portion of the left and right buildings 3 and 3 A separated from each other via a joint 2. The joint cover device 1 includes a ceiling joint cover 4 that covers a joint portion 2a of a ceiling portion, and a ceiling joint cover 4 that covers the joint portion 2a.
A plurality of ceiling joint covers attached to the left and right buildings 3, 3A in such a state that the both sides of the right and left buildings 3 and 3A are always urged to abut on the joints 2a of the ceiling portions of the left and right buildings 3, 3A. A mounting bracket 5, end covers 6, 6 slidably mounted on both ends of the ceiling joint cover 4 so as to protrude outward, and the end covers 6, 6 always protrude outward. Tension spring 7 urged as
7 is comprised.

Reference numeral 8 denotes an inner wall joint cover device which covers the joint portions 2b of the side walls of the left and right buildings 3, 3A.

As shown in FIG. 4, the ceiling joint cover 4 has a ceiling joint cover main body 9 formed in a lip grooved steel shape.
And tension spring locking pieces 1 formed at portions near both ends near both ends of the ceiling joint cover body 9.
0 and 10.

As shown in FIGS. 5 and 6, the ceiling joint cover mounting bracket 5 includes a support arm 11 bridged between the joints 2a of the ceiling portions of the left and right buildings 3, 3A, and a bridge above the ceiling. A ceiling joint cover attaching plate 13 having both ends formed with L-shaped support legs 12, 12 bridged to the ceiling portion between the joint portions 2a of the ceiling portion, and a substantially central portion of the ceiling joint cover attaching plate 13 A mounting bolt 15 that is rotatably mounted and penetrates a bolt insertion hole 14 formed substantially at the center of the support arm 11, and is locked by nuts 16, 16 screwed to the tip of the bolt 15. An urging spring 18 urges the bolt 15 interposed between the locking piece 17 and the support arm 11 upward to constantly urge the ceiling joint cover attaching plate 13 to the ceiling. .

As shown in FIGS. 7 and 8, the end cover 6 has an angle-shaped engaging piece 19 slidably attached at a substantially central portion thereof, and an engaging piece engaged with the engaging piece 19. It comprises two slide plates 21 and 22 having a portion 20, and tension spring attachment pieces 23 and 23 formed substantially at the center of the rear ends of the slide plates 21 and 22.

As shown in FIG. 9, the joint cover device 1 having the above structure has end covers 6, 6 at both ends of the ceiling joint cover 4.
And insert the tension springs 7, 7, 7 into the tension spring mounting pieces 23, 23, 23, 23 of the end covers 6, 6, and the tension spring locking pieces 10, 10, 10, 10 of the ceiling joint cover 4. , 7 and end covers 6, 6
Is installed so that it always projects outward.

The ceiling joint cover mounting plate 1 of the ceiling joint cover mounting bracket 5 arranged at a predetermined interval is provided.
3 is fixed using two screws 24, 24.

The joint cover device 1 configured as described above.
When the left and right buildings 3 and 3A swing vertically and horizontally due to an earthquake or the like, the swing movement is caused by the sliding movement of the plurality of urging springs 18 of the ceiling joint cover mounting bracket 5 and the ceiling joint cover 4 with the ceiling portion. The swinging movement in the front-rear direction is absorbed by the movement of the end covers 6, 6 always projecting outward due to the tensile force of the tension springs 7, 7, 7, 7 of the end covers 6, 6.

[0016]

Next, different embodiments of the present invention shown in FIGS. 10 to 12 will be described. In describing different embodiments of the present invention, the first embodiment of the present invention will be described.
The same components as those of the embodiment are denoted by the same reference numerals, and overlapping description will be omitted.

In the second embodiment of the present invention shown in FIGS. 10 to 12, the main difference from the first embodiment of the present invention is the end covers 6A, 6A, which are end covers 6A, 6A.
Is a channel-shaped engagement piece 19A, and two slide plates 21A having a channel-shaped engagement portion 20A formed at an L-shaped tip end slidably engaged with the engagement piece 19A,
In the point that the joint cover device 1A is configured using the end covers 6A, 6A formed in this way,
The same operation and effect as those of the first embodiment of the present invention can be obtained.

[0018]

[Effects of the present invention] As is clear from the above description, the following effects can be obtained in the present invention.

(1) A ceiling joint cover that covers the joints of the ceiling parts of the left and right buildings separated from each other via the joint part, and both rules of the ceiling joint cover always contact the ceiling parts of the left and right buildings. A plurality of ceiling joint cover mounting brackets to be attached to the left and right buildings while being urged, and two slides respectively slidably attached to at least one end of the ceiling joint cover so as to protrude outward. The left and right buildings are composed of an end cover consisting of a plate and two or more tension springs which urge the two slide plates of the end cover to always project outward. Even when rocking due to an earthquake, etc., in the front-rear, left-right direction and up-down direction, it moves following the rocking movement, preventing damage to the ceiling joint cover and preventing gaps from forming between the side wall surface and the end cover. It can be reliably prevented by ride movement.

(2) According to the above (1), the end cover is always urged outward by the tension spring so that the end cover is always urged outward. In addition, the tension spring can be easily mounted.

(3) According to the above (1), since the structure is simple, installation is easy and mounting can be performed at low cost.
