Construction connection structure for building deformation joint

Abstract

The invention discloses a construction connection structure for a building deformation joint. The construction connection structure comprises a concrete wall, the deformation joint, a bituminous waterproof sheet material layer, a waterproof elastic material connection band, L-shaped connectors, a stainless steel component A, connectors in the shape shown in the description, an elastic rubber band,a buried water-stop belt and a stainless steel component B, wherein the deformation joint is formed in the middle of the concrete wall, the bituminous waterproof sheet material layer is wrapped intothe portion, between concrete wall bodies, of the deformation joint, the stainless steel component A and the stainless steel component B are installed on the tops of the portions, on the two sides ofthe deformation joint, of the concrete wall, and the elastic rubber band, the buried water-stop belt and the waterproof elastic material connection band are sequentially arranged between the tops of the stainless steel components A and B from top to bottom. By means of the construction connection structure, the waterproof and anti-seep performance of the deformation joint are enhanced, the construction connection structure has sufficient expansion and contraction margins, pull crack breakage of the material is avoided or reduced, the construction connection structure is suitable for the building deformation joint which is large in joint width, and the problems are effectively solved that the deformation joint leaks, the waterproof sheet material is pulled apart, and the sheet material layer is damaged to lead to waterproof failure.

Description

technical field [0001] The invention relates to the field of construction, in particular to a construction connection structure of 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 f...

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.
