Description

  The present invention relates to a wall joint device for covering between wall surfaces such as inner wall surfaces and outer wall surfaces of left and right buildings installed via joint portions.

  Conventionally, the wall joint device installed between the wall surfaces of the left and right buildings has a structure in which, when the joint portion becomes narrow, the center portion protrudes inward to absorb the shaking motion.

Therefore, the conventional wall joint device uses a mechanism that slides in the left-right direction and a mechanism that slides in the front-rear direction, so the structure is complicated, the cost is high, and the slide movement is difficult to smooth. There was a drawback.
JP 2000-192558 A

  In view of the above-mentioned conventional drawbacks, the present invention can be installed between left and right buildings by only sliding in the left and right direction. Then, it aims at providing the joint device for walls which can absorb the shaking motion and can prevent damage.

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.

  In order to achieve the above object, the present invention provides a left and right rotating holder that is attached to a wall case on the joint portion side of a left and right building that is installed via a joint portion so as to be rotatable in the front-rear direction via a fixture. A central maintaining link in which at least two or more end portions are pivotally supported by the left and right pivot holders, and a center maintaining link that is always located in the center of the joint, and at least two or more center maintaining links. A rear end portion is attached to a support column pivotally supported by the central pivot portion so as to be located on the back surface of the link, and the left and right rotation holders, and approximately a quarter of the joint portion includes at least two or more of the joint portions. A left and right fixed joint cover formed with a stopper piece projecting forward at a predetermined portion of the front end portion so as to be supported by the front surface of the central maintenance link; and a stopper piece of the left and right fixed joint cover on the front surface of the column. Parts not located A plurality of left and right slide bodies mounted so as to be slidable in the left and right directions so that the front ends of the left and right fixed joint covers can enter, and the left and right slide bodies that slide left and right Left and right slide joint covers each having a locking piece to be engaged with a stopper piece of the left and right fixed joint cover at the front end portion to which the rear end portion is attached, and a plurality of support pieces fixed to the front surface of the column A central fixed joint cover that covers a portion of the left and right slide joint covers that is substantially fixed at the center, excluding the tip, and a right and left bias that constantly biases the left and right slide bodies or the left and right slide joint covers in the storage direction. The mechanism constitutes a wall joint device.

  As is clear from the above description, the present invention has the following effects.

A rear end portion is attached to the column pivotally supported by the central pivot portion and the left and right rotation holders, and approximately one quarter of the joint portion is supported by the front surfaces of the at least two central maintenance links. Left and right fixed joint covers formed with a stopper piece projecting forward at a predetermined part of the front end portion so as to cover, and a part where the stopper pieces of the left and right fixed joint covers are not located on the front surface of the column, Left and right fixed joint covers A plurality of left and right slide bodies that are slidably movable in the left-right direction so that the front end part can enter, and a tip that has a rear end attached to each of the left and right slide bodies that slide to the left and right The left and right slide joint covers having locking pieces to be engaged with the stopper pieces of the left and right fixed joint covers at the part, and the left and right sides having a substantially central part fixed to a plurality of support pieces fixed to the front surface of the support column Since the center fixed joint cover that covers the portion excluding the tip of the slide joint cover, and the right and left urging mechanism that constantly urges the left and right slide bodies or the left and right slide joint covers in the storage direction, The left and right slide joint covers can slide to the left and right to absorb the shaking movements of the left and right buildings due to earthquakes where the joints become narrower or wider. That.
Therefore, it is only necessary to move the left and right slide joint covers in the left-right direction, and the left and right slide joint covers can be moved smoothly.

(2) By said (1), the rocking | fluctuation motion of the different front-back direction of a right-and-left building can be absorbed by rotation of a right-and-left rotation holder.

(3) According to the above (1), the left and right fixed joint covers are supported by the central maintenance link, the front ends are locked with the front ends of the left and right slide joint covers, and the left and right slide joint covers are the central fixed joint covers. Since the portion excluding the tip portion is covered, it is possible to efficiently prevent the tip portions of the left and right fixed joint covers and the tip portions of the left and right slide joint covers from fluttering.

(4) According to (1), the left and right fixed joint covers, the left and right slide joint covers, and the center fixed joint cover having a small width can be used.
Therefore, transportation and installation work can be easily performed.

(5) In claim 2, the same effects as in the above (1) to (4) can be obtained.
