A waterproof connection structure for building deformation joints

Abstract

The invention discloses a waterproof connection structure for a building deformation joint. The waterproof connection structure comprises concrete walls, stainless steel components, polyethylene foamfilling blocks, a middle-buried type water stop belt, a pitch waterproof roll layer and a waterproof elastic material connecting belt. The deformation joint is arranged at the middle portions of the concrete walls, and the pitch waterproof roll layer is wrapped in the deformation joint between the concrete walls. The parts, on the outer sides of the pitch waterproof roll layer, of the concrete walls are provided with the stainless steel components. Each stainless steel component comprises a stainless steel plate A and a stainless steel plate B. The polyethylene foam filling blocks, the middle-buried type water stop belt and the waterproof elastic material connecting belt are sequentially arranged between the stainless steel plates A and the stainless steel plates B from top to bottom. Thewaterproof performance and the anti-seepage performance of the deformation joint are improved, the sufficient telescopic allowance is achieved, material tension fracture damage is avoided or reduced,and the waterproof connection structure can be suitable for building deformation joints with the large joint width. The waterproof connection structure effectively solves the problems that water seepsand leaks from the deformation joint, a waterproof roll is in tension fracture, a waterproof layer of the roll is damaged, and water prevention is in failure.

Description

technical field [0001] The invention relates to the field of construction, in particular to a waterproof connection structure for construction deformation joints. Background technique [0002] The waterproofing of building deformation joints is a difficult problem in underground engineering. The construction is difficult and the reliability of waterproofing is poor. The current construction technology of deformation joint waterproofing has lasted for nearly 50 years, and there is no perfect solution yet. According to relevant information, according to incomplete statistics, about 60%-70% of the deformation joints have water leakage to varying degrees. [0003] In the prior art, waterproof materials such as mid-buried waterstops, detachable Ω waterstops, external waterstops, and metal plate waterstops are generally used in waterproofing projects for waterproofing of building deformation joints. [0004] However, the most ideal waterproof measure for deformation joints is fu...

AI Technical Summary

Problems solved by technology

However, in the actual installation process, the expansion and contraction margin of the waterproof membrane is insufficient, and the waterproof membrane at the position of the deformation joint is cracked, destroying the waterproof layer of the membrane and making the waterproof failure

Moreover, a single form of waterproof membrane is insufficient in waterproof and anti-leakage performance, and it is difficult to assemble, resulting in slow construction speed and unreliable waterproof quality.
