Treatment and construction method for connecting part of roof waterproof structure deformation joint and external wall

Abstract

The invention relates to a treatment and construction method for a connecting part of a roof waterproof structure deformation joint and an external wall. The method at least comprises the following technological processes of steel bar embedding at one side of a roof deformation joint, measuring and paying-off, formwork erecting (side formwork at one side), wall body and cover plate steel bar binding, base layer clearing, formwork erecting (side formwork at the other side), concrete casting, formwork dismounting, base layer clearing, wall body buildingat the other side, flashing position constructing, wall body deformation joint constructing, wall body painting, JS waterproof paint brushing, roof flushing position waterproof layer constructing, waterproof filling embedding, and waterproof paint coating and brushing on the surface. By using structural design innovation on the roof deformation joint and the wall body deformation joint, under the condition of ensuring the use function (upward, downward, leftward and rightward free deformation) of the deformation joints, the seepage phenomenon occurring in the positions of the roof deformation joint and the wall body deformation joint can be avoided; the durability of the deformation joints is high; and cracking and damage cannot easily occur.

Description

technical field [0001] The invention relates to the technical field of anti-leakage valve applications, in particular to a construction method for treating the junction of deformation joints of roof waterproof structures and exterior walls. Background technique [0002] With the development of social economy and the dense population, high-rise buildings emerge as the times require. Because the higher the building is built, the higher the construction technology will be, and the quality of the house will be improved at the same time, and the phenomenon of water leakage is also obviously reflected. At present, solving roof and wall leakage has become a common concern of construction units and users. Although the current roof waterproof structure plays an important role in the use process, due to various unavoidable factors during the construction process, it cannot be completely Reliable guarantee, its leakage points mainly appear in the structural change parts (the connectio...

At present, solving roof and wall leakage has become a common concern of construction units and users. Although the current roof waterproof structure plays an important role in the use process, due to various unavoidable factors during the construction process, it cannot be completely Reliable guarantee, the leakage points mainly appear in the structural change parts (the connection between the deformation joint and the wall, the flooding part of the parapet and the gable wall), this problem has been plagued by the construction unit
