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

Embodiment Construction

[0030] The present invention will be described further in conjunction with accompanying drawing now.

[0031] A method for constructing waterproof joints of underground garage roof deformation joints according to the present invention mainly includes the following process steps:

[0032] 1. Cast-in-place bottom structure base 1;

[0033] 2. Lay a 100mm thick emulsified asphalt wood wool board 2 on the structural base;

[0034] 3. After the rough surface is chiseled on the upper end of the emulsified asphalt wood wool board 2, a waterproof blocking strip 3 is poured;

[0035] 4. Pour a trapezoidal waterproof protruding base surface 4 on the emulsified asphalt wood wool board 2 or pour the rough surface, and reserve a layer of cracks in the middle when pouring the waterproof protruding base surface 4;

[0036] 5. Lay a layer of waterstop waterproof layer 5 fully covered with SBS waterproof membrane or self-adhesive waterproof membrane on the inner wall of the gap, and then ins...

Abstract

The invention relates to the technical field of building design, and particularly discloses an underground garage roof deformation joint waterproof joint and a building method thereof. The joint comprises a structural base layer, a trapezoid waterproof protruding layer, a trapezoid waterproof roll addition layer, a trapezoid waterproof layer, a structural layer and an overlaying soil layer which are sequentially connected from bottom to top. A water stop belt is installed in the middle of the waterproof protruding layer, a water stop belt waterproof layer is laid at the inner side wall of thewater stop belt, a caulked joint is arranged at the upper end of the water stop belt, the caulked joint is filled with a waterproof ointment, a wooden plate is laid at the joint of the bottom end of the waterproof protruding layer and the structural base layer, and at least one waterproof blocking strip is poured on the wooden plate. The building method mainly adopts the back pouring embedded method. The technical problems that a traditional waterproof treatment joint is excessively complex, construction is not facilitated, the constructed effect is not good, and repair is not treated appropriately are solved.

Description

technical field [0001] The invention relates to the technical field of architectural design, in particular to a waterproof joint of deformation joints on the 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. Deformation joints are often set up to solve the structural shrinkage and deformation caused by unfavorable factors such as complex and irregular shapes of underground buildings and super-long structures. 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. And when the waterproof treatment...
