Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall surface joint device that covers joint portions between inner wall surfaces and outer wall surfaces of left and right buildings built via joint portions.
[0002]
[Prior art]
A conventional wall joint device attaches a joint cover that can cover the wall portions of the left and right buildings near both ends of the joint portion at both ends, and this joint cover is always in contact with the wall portions of the left and right buildings. It consists of a fixture.
[0003]
[Problems to be solved by the invention]
The conventional wall joint device has a drawback that a wide joint cover must be used in order to cover the joint portion with the joint cover even if the joint portion becomes wide due to an earthquake or the like. It was.
In addition, when the joint cover is slightly larger than the width of the joint part, the above-mentioned drawback can be solved, but when the joint part becomes wide, both ends of the joint cover are left and right buildings. The joint covers and fixtures were damaged by the left and right building enclosures when they came off the wall and returned to their original positions.
[0004]
In view of the above-mentioned conventional drawbacks, the present invention reliably prevents the joint cover from entering the joint part and damaging it when returning to the original part even if the joint part becomes wide without using a large joint cover. An object of the present invention is to provide a wall surface joint device that can open a joint cover as easily as a door when necessary.
[0005]
The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.
[0006]
[Means for Solving the Problems]
To achieve the above object, according to the present invention, one end portion covering the joint portion between the wall surfaces of the left and right buildings built via the joint portion is rotatably attached to the housing of one building via a hinge member. A joint cover in which the other end portion is slidable along the wall surface of the other building, and the other end portion which is a free end portion of the joint cover is always biased so as to abut against the wall surface of the other building. When the joint and the other end, which is the free end of the joint cover, are spread due to an earthquake or the like, a coil spring or rubber is attached between the gap of the joint to prevent the joint from entering the joint. A joint device for a wall surface is constituted by a joint cover intrusion prevention rod such as a wire stretched through a force member.
[0007]

A shaft portion 15 having a shape and a C-shaped bearing portion 16 attached to the shaft portion 15 so as to be rotatable by a predetermined amount are fixed to the frame body 9 of the joint cover 5 by a plurality of screws 17 or the like. And the other mounting plate 18.
[0011]
As shown in FIG. 6, the urging mechanism 6 is fixed to the housing 3 b at the end of the joint 2 of the other building 3 by a plurality of screws 19, and the joint cover 5 side is formed on the inclined surface 20. The guide member 21 is guided, and is guided by the guide member 21, one end is fixed to the free end side reinforcing bar 10 of the joint cover 5, and the other end is a lower position of the guide member 21 of the other building 3. And a joint cover urging rod 23 such as a rope or a wire, which is stretched through an urging member 22 such as a coil spring or rubber, fixed to the housing 3b.
In the embodiment of the present invention, a joint spring urging rod 23 formed of a coil spring and a wire is used.
[0012]
As shown in FIG. 7, one end of the joint cover intrusion prevention rod 8 is fixed to the inclined surface 20 of the guide member 21 of the biasing mechanism 6, and the other end is attached to one mounting plate 14 of the hinge member 4. It is fixed to the housing 3 b of the lower position of the guide roller 24 of one building 3 through the attached guide roller 24.
In the embodiment of the present invention, the joint cover intrusion prevention rod 8 formed of a coil spring and a wire is used.
[0013]
In the wall joint device 1 having the above configuration, when the left and right buildings 3 and 3 are shaken by an earthquake or the like and the joint portion 2 becomes narrow, the free end portion of the joint cover 5 is the other building 3 as shown in FIG. Is slid on the wall surface 3a to absorb the shaking motion.
[0014]
When the joint portion 2 becomes wide, the joint cover 5 moves together with the one building 3 as shown in FIG. 9, and the free end portion of the joint cover 5 moves from the wall surface 3 a of the other building 3. Although it leaves | separates, it will be in the state which contacted the joint cover penetration | invasion prevention rod 8 and was prevented from invading into the joint part 2.
When the joint cover 5 returns to its original position, the free end portion of the joint cover 5 slides along the joint cover intrusion prevention rod 8 and is guided to the wall surface 3 a of the other building 3.
[0015]
When the left and right buildings 3 and 3 swing in different front and rear directions, the joint cover 5 can be rotated by the hinge member 4 as shown in FIG. 10 to absorb the swinging motion.
[0016]
