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, this type of floor joint device has formed joints between the left and right floor frames in order to absorb the shaking movement at the time of an earthquake, and uses joint plates having a width of about twice the width of the joints. ing.
However, in the case of a seismic isolation building, a joint with a large width must be provided, but it cannot be installed unless there are sufficient dimensions between the joint and the boundary line, or between the joint and the wall or pillar. There were drawbacks.

  For this reason, using a joint plate with a width dimension slightly larger than the width dimension of the joint section, the panel body that supports the joint plate at the time of an earthquake, and when the joint section becomes narrow, the lower part is attached to the housing via the hinge member, There is considered a floor joint device in which an upper portion is supported by a plate-like support member attached to a panel body via a hinge member.

  However, since such a floor joint device uses a plate-like support member, there is a disadvantage that sufficient strength cannot be obtained and a joint plate filled with heavy mortar or cement cannot be safely supported. .

  In order to eliminate this defect, it is conceivable to use a pipe material for the support member. However, since the support member is located in the joint part, there is a disadvantage that the width dimension of the joint part becomes small.

JP 2004-150231 A

  In view of the conventional drawbacks as described above, the present invention can safely support a heavy joint plate in a state where sufficient strength is obtained without reducing the width dimension of the joint part, and the joint part and the boundary line. It is an object of the present invention to provide a floor joint device that can be used safely by absorbing the expansion and contraction movement corresponding to the joint portion width dimension.

  Another object of the present invention is to allow the joint plate to move in an approximately parallel state with at least two brackets and an inclined surface of the joint plate slide support recess when the joint plate moves upward. An object of the present invention is to provide a floor joint device that can be used.

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 joint plate slide support recess having an inclined joint surface formed on the floor surface in the vicinity of the joint portion side portion of one floor frame through the joint portion, The rear end portion is pivotally supported in an inclined state so that the front end portion is positioned upward by turning to the joint portion side portion of the floor case, and the front end portion is perpendicular to the wall surface of the joint portion side portion of the one floor case. At least two or more plate-like brackets that are long in the vertical direction and are tilted so as not to become tilted, and at least two or more brackets are pivotally supported so that the rear end is movable at least upward. The joint is supported at the tip of the joint plate slide support recess, and the rear end can be moved upward to the joint side part of the other floor frame so that it can slide on the joint cover. Supported by Tip constitutes the floor joint device between joint plate covering the joint plate slide support recess.

As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, since at least two or more brackets that are long in the vertical direction are used, a large load in the vertical direction can be supported.
Therefore, a heavy joint plate filled with mortar or concrete can be safely supported.
(2) When at least two brackets are narrowed at the joint, they are pressed and rotated by the other floor frame, and when the pivot is turned, the tip of the bracket is positioned above, so the joint cover and joint plate can be moved to the joint plate slide. It can be moved upward in a substantially parallel state with the inclined surface of the support recess.
Therefore, since the joint plate does not become inclined when the joint plate is pushed upward as in the prior art, it can be used safely.
(3) By forming the joint plate slide support recess in the vicinity of the joint part according to (1), it is possible to use a joint plate that is slightly larger than the width dimension of the joint part.
Therefore, if the same width dimension as the width dimension of the joint portion is between the joint portion and the boundary line, it can be installed.
Therefore, it can be installed even in a narrow space between the joint portion and the boundary line.
(4) In the second aspect, the same effects as in the above (1) to (3) can be obtained, and the joint cover is pivotally supported by at least two brackets so as to be movable in the horizontal direction. When moving, it can be slid left and right.
(5) In claim 3, the same effects as in the above (1) to (3) can be obtained, and at least two brackets are supported by the support means on the side surface of one floor frame and the joint of the other floor frame. Since it is not perpendicular to the side surface, even if at least two or more brackets are pressed by the joint surface of the other floor frame, it can be smoothly rotated.
