Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an expansion joint for covering a gap of a structure appearing on a roof surface of a building, and particularly to a new expansion joint for roof which has a simple structure and is easy to install.

[0002]

[Prior Art]

 Since a structure is constantly distorted due to expansion and contraction due to temperature changes, unequal subsidence, and earthquakes, etc., a gap structure is configured as a means to prevent destruction of the structure caused by such distortion, and even on the roof surface of the structure. Since this gap appears, a roof expansion joint is used as a structure that covers this gap so that it can be expanded and narrowed and level difference can be absorbed during use. Various types of expansion joints for roofs have been used in the past, but they had the problem that they were difficult to keep away from rain and the structure became complicated.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object thereof is to provide an expansion joint for a roof having a new structure that does not have a complicated structure, is simple in construction, and can ensure a reliable rain finish. Is to

[0004]

[Means for Solving the Problems]

 The expansion joint for roof of the present invention is an expansion joint to be installed in the strain absorbing gap appearing on the roof part of a building, and in the gap direction at the upper edge of the standing wall part that stands up from the base plate part in an L shape. A bent support edge is formed integrally or integrally, and a guide rail that bends in the lower surface direction and extends in the longitudinal direction is formed at the end edge of the support edge. A pair of frame bases that are fixed to face each other, a connecting plate that hangs on the supporting edges of both frame bases, and both side edges are bent and hung outside the frame base, and both frame bases A suspension in which two guide rollers are rotatably attached to the upper surfaces of both ends of the rod, which are longer than the distance between the guide rails of the table, so as to be rotatable, and a fastening bolt is inserted in the center of the rod. And a top plate portion having a chevron section, which is provided on the upper surface of the connecting plate and has both side edges bent to the outside of the side edge of the connecting plate. And a cover member that fastens both side edges, and a connecting plate that is hung on both frame bases, and two guide rollers each on the guide rails of both frame bases at appropriate intervals in the longitudinal direction. The gist of the invention is that it is tightly fixed with a suspending member attached so as to sandwich it and a fastening bolt. Further, it is desirable that the fastening bolt of the suspending member be elastically biased to the rod body in the fastening direction via a coil spring.

[0005]

[Action]

 According to the above structure, the connecting plate is attached to the suspending member pivotally mounted at both ends slidably between the frame bases by the fastening bolts, and the cover member is covered and fixed to the connecting plate. Since the construction work is extremely easy and the cover member is instructed so that the cover member is always located in the center of the gap by the suspending member, there is no bias, and high reliability of rain is obtained. .

【Example】

 An embodiment according to the present invention will be described below with reference to FIGS. Reference numerals 1 and 1 denote frame bases made of aluminum drawn objects fixed to the upper surfaces of the roof edges of the frames a and b, which are opposed to each other with a gap G interposed therebetween, and each stand from the base plate 1a in an L shape. A support edge 3 which is bent in the gap G direction is integrally formed on the upper edge of the standing wall portion 2, and a guide rail 4 which is bent in the lower surface direction is formed in the longitudinal direction at the end edge of the support edge 3. The frame bases 1 and 1 are fixed to the upper surfaces of the frames a and b by anchor bolts 5 so that the guide rails 4 and 4 are parallel to each other.

Further, reference numeral 6 is a draining member fixed to the outside of the standing wall portion 2 of the frame base 1, and the hem portion 7 is located at a step portion c lower than the upper surfaces of the skeletons a and b. In addition, a water repelling seal 8 is formed between the upper end portion of the water draining member 6 and the standing wall portion 12, which is made of an elastic material such as neoprene rubber and has a sliding contact lip curved outward in the longitudinal direction. It becomes.

A connecting plate 9 made of an aluminum-drawn material is hung on the supporting edges 3 and 3 of the frame bases 1 and 1 so as to be slidable in the width direction. , 1 has a structure in which side edges 10, 10 are bent and hung at a sufficient distance on the outer side of the first and second parts, and a bolt insertion hole is arranged in the longitudinal direction at an appropriate interval in the center.

Since the connecting plate 9 is fastened to the suspending member 11 by using the bolt insertion hole, the suspending member 11 is more than the distance between the guide rails 4 and 4 of the frame bases 1 and 1. Also, two guide rollers 13 and 13 are rotatably mounted on the upper surfaces of both ends of the sufficiently long rod 12 with a small gap into which the plate thickness of the guide rail 4 can be tiltably inserted. A fastening bolt 16 into which a coil spring 15 having appropriate elasticity is externally inserted is inserted into a small hole 14 formed in the center of the rod body 12 from the lower surface side, and is fixed by a nut 17.

In the connecting plate 9, the fastening bolts 16 are inserted into the bolt insertion holes from the lower surface side while the guide rollers 13, 13 at both ends are engaged with the guide rails 4, 4 of the frame bases 1, 1. When the nut 18 is fastened, the elastic force of the coil spring 15 is applied between both members by the fastening of the nut 18, so that the connecting plate 9 is held stably.

Reference numeral 19 is a bar member that covers the upper surface and side surface of the connecting plate 9, and is bent and hung by an aluminum pulling member to the outside of the top plate portion 20 having a chevron cross section and the side edges 10 and 10 of the connecting plate. The side edges 21 and 21 are formed, and the lower end portions of both side edges 10 and 21 are fastened and integrated by a small screw 22. In the drawing, 23 is the hem portion 7 of the draining member 6 and the skeletons a and b. Caulking material filled in between, 24 is a water stop plate provided in the gap G, and 25 is a fireproof belt.

In the expansion joint for roof having the above-mentioned structure, when the gap G is widened, a pair of guide rollers 13, 13 pivotally mounted on both ends of the suspending member 11 are arranged in the longitudinal direction along the guide rails 4, 4. The connecting plate 9 is slidable, and at this time, the connecting plate 9 attached to the rod body 12 by the fastening bolts 16 is always tightened stably by the elastic force of the coil spring 15.

[0013]

[Effect of the device]

 As described above, in the expansion joint for roof according to the present invention, the connecting plate is attached to the suspending member having both ends slidably mounted between the frame bases by the fastening bolts, and the cover member is attached to the connecting plate. Since the structure is such that the cover is adhered and fixed, the construction work is extremely easy, and the cover member is stably supported by the suspending member so that it is always located in the center of the gap, and there is no bias. For this reason, it has various excellent characteristics such as high reliability of rain shut-off, and the effect after implementing the present invention is extremely large.
