Deformation joint structure and construction method thereof

Abstract

The invention relates to a deformation joint structure and a construction method thereof. The deformation joint structure comprises a water stopping belt, a tongue-and-groove support and a flexible caulking plate, wherein the two ends of the water stopping belt are embedded into a first concrete structure and a second concrete structure; the tongue-and-groove support is formed at the bottom of the first concrete structure and extends to the bottom of the second concrete structure, and the tongue-and-groove support is arranged in the manner of corresponding to the embedding end, embedded in the second concrete structure, of the water stopping belt; and the flexible caulking plate is clamped between the first concrete structure and the second concrete structure and comprises a bottom caulking plate body supported between the tongue-and-groove support and the water stopping belt and a top caulking plate body erected above the water stopping belt. A connector of a deformation joint is tight, the tongue-and-groove support is arranged at the bottom of the deformation joint, the rigid waterproofing structure is additionally arranged, the water stopping belt is arranged at the upper portion of the tongue-and-groove support, the flexible waterproof function is achieved, a sealant is arranged at the top of the deformation joint for achieving the waterproof function, the overall waterproof performance is good, the anti-deformation capacity is high, and the structure reliability of the deformation joint is high.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a deformation joint structure and a construction method thereof. Background technique [0002] Conventional building foundations have cushions, on which a waterproof layer is made, and then the structural concrete foundation is poured on the waterproof layer. However, conventional municipal structures such as river channels, box culverts, and large equipment pits do not have concrete cushions and waterproof layers, and large structures cannot be constructed at one time. The treatment of joints between successively constructed concrete structures is particularly important. Existing deformation joints The structure is to fill the deformation joint between the front and rear concrete structures with sealant, and the middle part of the deformation joint is provided with a waterstop buried in the front and rear concrete structures, but only the deformation joint structure formed b...
