Description
Technical Field
The invention belongs to the field of building construction, and particularly relates to a basement roof deformation joint waterproof and drainage integrated system and a construction method.
Background
At present, waterproof structures of a buried water stop and an externally attached water stop or a detachable water stop are commonly adopted in the design of deformation joints of a top plate of a basement. In the construction process of the basement roof structure, the embedded water stop is required to be pre-buried in advance, and meanwhile, the externally attached water stop or components required by pre-buried installation of the detachable water stop are required to be constructed in the construction process of the basement roof concrete structure. The embedded water stop and the externally attached water stop or the detachable water stop are used for providing two waterproof structures for deformation joints of the roof of the basement.
(1) The existing deformation joint structure is complex in construction process and low in operability. Because the embedded rubber water stop needs to be pre-embedded in advance, and the embedded water stop is positioned in the middle of the structure without any supporting and fixing positions, how to install and fix the embedded rubber water stop needs to be considered. When the two sides of the deformation joint are structural beams, the embedded water stop belt cannot be directly embedded due to the influence of beam stirrups, and the structural structure is designed independently to meet the installation conditions. Meanwhile, the rubber water stop is made of flexible materials and soft in texture, so that the problems of bending, kinking, inextensibility and the like are very easy to occur in the fixing process, and the waterproof effect is very easy to influence. The invention aims to solve the problem of difficult installation of the embedded water stop, search for a simpler installation mode and simultaneously search for a waterproof structure which is not influenced by the structure types (beams or plates) at two sides of the deformation joint.
(2) The existing deformation joint structure has weak capability of resisting deformation and preventing waterproof damage. Whether it is external-attached type waterstop or detachable type waterstop, when the displacement deformation occurs to the structures at two sides of the deformation joint, the adhesion part of the rubber waterstop and the concrete structure is easy to crack and destroy, and the water seepage channel is easy to generate, so that the waterproof layer of the rubber waterstop at the outer side is disabled, and the hidden trouble of seepage is generated. Meanwhile, the embedded rubber water stop is directly contacted with the concrete structure, and when the structures at two sides of the deformation joint are unevenly settled, sharp stones in the concrete structure are extremely easy to damage the embedded rubber water stop, so that the leakage problem is generated. The invention aims to improve the deformation resistance of the basement deformation joint structure, can adapt to the structural deformation of the two sides of the top plate of the basement and does not generate waterproof damage.
