Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint device between adjacent building frames.

[0002]

2. Description of the Related Art Generally, in order to prevent rainwater from flowing down through the gaps between buildings which are arranged side by side with a gap of about 50 mm to 100 mm, between the rising skeletons such as parapets at the top of the buildings. It is necessary to install an expansion joint device.

An example of such an expansion joint device is shown in FIG. This is one in which one end of the cover material 65 is locked and held by the holding member 60 provided on the wall skeleton a ′, and the other end is placed on the support member 1 of the rising skeleton a. In the device F, the holding member 6
0 is a locking groove 61 that opens downward at the upper end of the fixed edge 60a.
The protruding edge 60b that forms the shape is bent into a hook shape, and the water stop plate fitting groove 60c is formed at the lower end.
On the inner side of the opening end of the locking groove 61, a locking uneven strip 62 is formed. The holding member 60 is fixed by screwing the fixed edge 60a to the wall body a ', and
An exterior material 63 and a caulking seal material 64 are provided above the b. The cover material 65 is formed by forming a hanging edge 65b at one end of the rising edge 65a and providing a locking edge 65c at the other end, and an engaging edge of the holding member 60 is provided at an upper end portion of the locking edge 65c. A locking jaw 66 is formed which is locked to the locking uneven strip 62 of the stop groove 61. Hanging edge 6 of standing edge 65a
The portion on the 5b side is placed on the airtight material 6 fitted to the support member 1 of the rising frame a.

However, this is a construction in which the cover material 65 is pulled up from the bottom so that the locking jaw portion 66 of the locking edge 65c is locked in the locking groove 61, and the cover material 65 resists the load thereof. Moving up is not only a very troublesome operation, but also has the drawback that the cover material 65 easily separates from the support member 1 due to strong wind or the like.

On the other hand, the one disclosed in Japanese Utility Model Laid-Open No. 48-19409 is also known, and similarly, when one of them is a rising frame and the other is a wall frame, it is horizontally arranged between the building frames. A cover member is formed by forming an edge and an upright edge into an L shape, and a pair of upper and lower engaging portions are formed upward on the wall body side, and the above-mentioned engagement is provided on the back side of the upright edge of the cover material. A downward locking portion corresponding to the stopper is formed, and the locking portions are locked while the cover material is pressed downward in parallel along the wall body surface.

In this case, the locked state is good, but if the cover material is pressed downward in parallel along the wall body surface, the lower surface of the horizontal edge will hit the upper surface of the standing body and can be pushed further down. Can not. For this reason,
Since the locking work must be performed by applying a large force while properly controlling the posture of the cover material, the work is still very troublesome.
