Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a joint device for closing off the gap between the two building frames of buildings that are juxtaposed side by side.

[Conventional technology]

Conventionally, joint devices of this type have various structures. For example, JP-A-60-
The joint device disclosed in No. 13155 attaches a cover plate with a spring member that provides a reversal elastic force.

[Problem that the invention attempts to solve]

However, with structures that use such conventional spring members, when the clearance between the two frames becomes large to a certain extent, it becomes difficult to manufacture due to the shape and dimensional constraints of the spring members, so it is necessary to add a lot of reinforcement, or It will have to be extremely large. In addition, if the clearance changes significantly during an earthquake, and furthermore, both the building blocks vibrate inward and outward directions to a certain extent or more, it will not be possible to adequately cope with the situation. There was also the problem that the large clearance and large adaptability would make it extremely expensive. Another problem was that the installation work was difficult. In particular, when the cover plate was pulled outward by wind pressure (negative pressure), there was a risk that it could not withstand it and come off.

The object of the present invention is to provide a joint device for buildings that can solve the above-mentioned problems of the conventional art.

[Means for solving problems]

The joint device for buildings of the present invention includes a pair of edge members that are fixed to the edges of opposing building blocks with a predetermined clearance and have longitudinal grooves that open inward; a cover plate for covering the gap from the outside; having engagement protrusions at both ends that slidably engage with the grooves of the edge material; and a back surface of the cover plate; a bridging rod attached to the side via a connector; a first locking device attached to the edge material; and a second locking device that locks to the first locking device and is attached to the back surface of the cover plate. and a holding and pressing piece that holds the first and second locking devices in a locked state, and is attached to the first locking device so as to be movable in the longitudinal direction of the cover plate. 1. A joint device for a building, comprising: an adjustment tool comprising: a falling-off prevention member;

[Effect]

With the above configuration, the engaging protrusions at both ends of the bridging rod slide while engaging with the grooves of the pair of edge members on the back side of the cover plate, and the entire bridging rod swings. This allows it to adapt to changes in the clearance between both bodies.

In addition, on the back side of the cover plate, the engaging protrusions at both ends of the bridging rod slide while engaging with the grooves of the pair of edge members, and the entire bridging rod swings in the inward and outward directions. Flexibly adapts to changes in the internal and external directions of both body parts.

Of course, it is possible to simultaneously adapt to the two types of changes between the two bodies, and the amount of adaptation is extremely large.

Furthermore, due to changes in the longitudinal direction of the cover plate,
This is achieved by attaching an adjustment tool for the falling-off prevention member so as to be movable in the longitudinal direction. Moreover,
In the attached state, the cover plate is held by the edge material via the falling-off prevention member, thereby preventing the cover plate from falling off. In addition, if the fall prevention member is attached to the edge material before the cover plate is attached to the edge material via the bridging rod, the cover plate can be attached to the edge material while the fall prevention member holds the cover plate. Can be installed.

In the state where the bridging rod 23 is attached in advance to the a side, the bridging rod 23 is held in a pinched manner by the first elastic member 34 and the second elastic member 35 of the connecting tool 31, so that the bridging rod 23 The rod 23 does not wobble, and the rotation of the bolt 32 can be accurately transmitted to the bridging rod 23 via the nut member 33. Therefore,
Even if the clearance L is different in size, the engaging protrusions 27, 27 can be accurately and easily engaged with the grooves 13, 13.

[Effect of idea]

The joint device of the present invention has a drop-off prevention member 41
are attached to the edge members 4 and 5, and the bridging rod 23 is attached in advance to the back surface 20a side of the cover plate 20 using the connector 31, and the cover plate 20

is attached to the edge materials 4 and 5, and the attachment work is simple.

Moreover, since the bridging rod body 23 in the form of a strip or a rod is used, the joint device becomes particularly suitable when the clearance L is large. In other words, a simple shape. The bridging rod 23 of the structure allows bridging between the frames 1 and 2 having a large clearance L while maintaining sufficient strength and rigidity. In particular, even when the cover plate 20 is strongly pulled by wind pressure (negative pressure), the bridging rod 23 can sufficiently withstand it.

Of course, there are fluctuations in which the clearances L of the frames 1 and 2 increase or decrease relative to each other as shown by arrows M and N, fluctuations in the direction shown by arrow B, fluctuations in the longitudinal direction of the cover plate, and combinations of these. It responds flexibly to fluctuations with a large amount of adaptation.

Furthermore, since the cover plate 20 is held by the edge members 4 and 5 through the falling-off prevention member 41 in the attached state, the cover plate 20 can be prevented from falling off when subjected to excessive fluctuations such as during an earthquake. It will be planned. Furthermore, if the fall prevention member 41 is attached to the edge members 4 and 5 before the cover plate 20 is attached to the edge members 4 and 5 via the bridging rod 23, the cover plate 20 can be held by the fall prevention member 41. The cover plate 20 can be attached to the edge members 4 and 5 while the cover plate 20 is being moved, making the attachment work extremely easy.
