Abstract

PROBLEM TO BE SOLVED: To provide a joint device for a floor, which can be safely used by efficiently inhibiting a joint plate from causing a rattle or incurring danger because its height is different from the heights of right and left floor surfaces, even when right and left floor skeletons cause differential settlement.SOLUTION: In this joint device 1 for the floor, a joint plate slide supporting recess 6 for supporting the joint plate 8 in a horizontally slidable manner is provided in both or either of the right and left floor skeletons, on the side of the joint portion, of the right and left floor skeletons 3 which are provided via the joint portion 2. A surface, abutting on the joint plate, of the joint plate slide supporting recess, is formed as an inclined plane 5 having the other side of the joint portion set gradually higher than the side of the joint portion.

Description

  The present invention relates to a floor joint device that covers a space between right and left floor frames provided via joint portions.

  Conventionally, in this type of floor joint device, a joint plate slide support concave portion having an inclined anti-joint portion is formed on the joint portion side of one floor frame, and the other floor corresponding to the joint plate slide support concave portion is formed. A joint plate support recess is formed in the joint side portion of the housing, the tip is supported by the joint plate slide support recess, the rear end is supported by the joint plate support recess, and the tip can be rotated upward. A joint plate having a rear end attached to the joint plate supporting recess is used.

  The floor joint device constructed in this way can efficiently absorb the shaking motion of an earthquake where the joint part becomes wider or narrower, but when the left and right floor frames sink unevenly, the joint plate plate slide support The joint part side end of the concave part comes into contact with the bottom surface near the center part of the joint plate, and the joint plate has the disadvantage that it becomes loose and dangerous, and the heights of the left and right floor surfaces and the joint plate are different, There was a drawback that it was dangerous and could not be used safely.

Japanese Patent No. 3,854,872

  In view of the above-mentioned conventional drawbacks, the present invention can cause the joint plate to become loose even when the left and right floor frames sink unevenly, or may become dangerous because the height differs from the height of the left and right floor surfaces. An object of the present invention is to provide a floor joint device that can be efficiently blocked and used safely.

  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 supports a joint plate slidably movable in the left-right direction on both or one of the left and right floor housings on the joint portion side of the left and right floor housings provided via the joint portion. A floor joint device having a joint plate slide support concave portion, wherein the joint plate slide support concave portion is formed on an inclined surface in which the surface of the joint plate slide support concave portion which is in contact with the joint plate side is sequentially higher than the joint portion side. It is composed.

As is clear from the above description, the present invention has the following effects.
(1) A floor having joint plate slide support recesses for supporting the joint plate so as to be slidable in the left-right direction on both or one of the left and right floor housings on the joint portion side of the left and right floor housings provided via the joint portion. In the joint device, since the surface of the joint plate slide support recess that comes into contact with the joint plate is inclined so that the joint portion side is gradually higher than the joint portion side, the left and right floor frames are sunk unevenly due to an earthquake or the like. In addition, it is possible to efficiently prevent the joint plate from coming into contact with the joint portion side end of the joint plate slide support recess.

Therefore, the left and right floor surfaces and the upper surface of the joint plate can be kept substantially flush with each other, and the center portion of the joint plate can be used as a fulcrum as in the past to reliably prevent rattling. it can.
(2) According to the above (1), the joint plate slide support concave portion may be inclined so that the joint portion side is sequentially lowered, so that the structure is simple and can be easily installed.
(3) According to the second aspect, the same effects as in the above (1) and (2) can be obtained, and since only the guide member needs to be installed, the installation work can be easily performed in a short time.
