Waterproof structure of building construction roof expansion joint

Abstract

The invention relates to the technical field of roof expansion joint waterproofing, in particular to a building construction roof expansion joint waterproof structure which comprises roof panels, an expansion joint is arranged between the roof panels, and a first water stop reversed beam and a second water stop reversed beam are vertically poured on the roof panels and located on the two sides of the expansion joint. A pair of water stop steel plates which are extruded and fixed by one-way telescopic rods are arranged between the expansion joints, and a water stop transverse top plate which covers the first water stop reversed beam is transversely arranged at the upper end of the second water stop reversed beam. And meanwhile, the storage groove is formed in the water stop reversed beam, the end of the waterproof coiled material is folded and stored, the waterproof stability effect is effectively improved, and therefore the phenomenon that accumulated rainwater flows back from the expansion joint is avoided.

Description

technical field [0001] The invention relates to the technical field of roof expansion joint waterproofing, in particular to a waterproof structure for roof expansion joints in building construction. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation, such as walls, floors, and roofs (except wooden roofs), into two independent parts, so that buildings or structures can be horizontally expanded along the long direction to prevent cracks in the house due to climate change. The method is: reserve gaps at certain distances along the length of the building, and disconnect the building from all components above the ground su...

AI Technical Summary

Problems solved by technology

[0003] At present, the waterproofing of expansion joints on the roof of existing buildings generally uses water-stop beams directly to block the roof water. This phenomenon is a common problem of roof waterproofing, which leads to water seepage in the roof and expansion parts, and rainwater is easy to accumulate in the gaps between the joints of the water-stop anti-beams, and then further affects the wall below the expansion joints, making the outer wall Internal water seepage has seriously affected the use of the owner's house

[0004] To this end, a waterproof structure for roof expansion joints of building construction is provided to solve the problem of fixed installation of the ends of waterproof membranes
