Waterproof joints and construction methods of roof deformation joints in underground garages

Abstract

The invention relates to the technical field of architectural design, and specifically discloses a waterproof joint for deformation joints on the roof of an underground garage and a construction method thereof, including a structural base layer connected in sequence from bottom to top, a trapezoidal waterproof protruding layer, and a trapezoidal waterproof coiled material attachment layer, a trapezoidal waterproof layer, a structural layer, and a soil covering layer. A waterstop is installed in the middle of the waterproof protruding layer. A waterstop waterproof layer is laid on the inner wall of the waterstop. The upper end of the waterstop is provided with an embedded The caulking is filled with waterproof ointment, a wooden board is laid at the joint between the bottom of the waterproof protruding layer and the structural base, and at least one waterproof blocking strip is poured on the wooden board. The construction method mainly adopts the method of post-pouring and mid-burying. The invention solves the technical problems such as the traditional waterproofing treatment nodes are too complicated and unfavorable for construction, and if the effect is not good after construction, it is not suitable for repairing and other technical problems.

Description

technical field [0001] The invention relates to the technical field of architectural design, in particular to a waterproof joint of a deformation joint of a roof of an underground garage and a construction method. Background technique [0002] At present, the use of underground space is becoming more and more common, and deformation joints are often set to solve the structural shrinkage and deformation caused by unfavorable factors such as complex and irregular shape and super-long structure of underground buildings. At present, the waterproof structure of basement deformation joints usually adopts buried or externally attached rubber waterstops, but the rubber waterstops may lose waterproof due to excessive shear or axial deformation, poor protection, long-term use and aging and other factors. function, and because in most cases, the construction is pre-buried in advance and cannot be replaced, there is a lack of effective repair methods in the later stage. And when the wa...

Problems solved by technology

At present, the waterproof structure of the deformation joints in the basement usually adopts the buried or external rubber waterstop, but the rubber waterstop will lose its waterproof due to excessive shear or axial deformation, poor protection, and long-term aging. Function, and because most of the cases are pre-buried in advance of construction and cannot be replaced, there is no effective repair method in the later stage
