Description

Slot type reserved joint construction structure

Technical Field

The utility model belongs to the construction field, concretely relates to slot type reserves seam construction structures.

Background

At present, the waterproof structure design of the reserved seam of the top plate of the basement generally adopts a waterproof structure combining a buried water stop and an externally-attached water stop or a detachable water stop. In the basement roof structure work progress, need bury formula waterstop in advance in pre-buried, need paste formula waterstop or the required component of pre-buried installation detachable waterstop outward in the construction of basement roof concrete structure work progress simultaneously. Two waterproof structures are provided for reserved seams of the top plate of the basement by the buried water stop and the externally attached water stop or the detachable water stop.

The existing reserved seam structure has the disadvantages of complicated construction process and low operability. Because the buried rubber waterstop needs to be pre-buried in advance, and the buried rubber waterstop is located in the middle of the structure and does not have any support or fixed position, how to install and fix the buried rubber waterstop needs to be considered. When the both sides of the reserved joint are structural beams, the embedded water stop cannot be directly embedded due to the influence of beam stirrups, and the structural structure needs to be designed independently to meet the installation condition. Meanwhile, the rubber water stop is made of flexible materials and is soft in texture, so that the problems of bending, kinking, non-stretching and the like are easily caused in the fixing process, and the waterproof effect is easily influenced. The utility model discloses bury formula waterstop installation difficulty problem in wanting to solve, seek simpler mounting means, look for the waterproof structure that does not receive reserved joint both sides structural style (roof beam or board) to influence simultaneously.

Secondly, the existing reserved seam structure has weak capability of resisting deformation and preventing water damage. No matter the external-sticking type water stop belt or the detachable type water stop belt, when the structures on the two sides of the reserved joint are displaced and deformed, the adhesion part of the rubber water stop belt and the concrete structure is easy to crack and break, and a water seepage channel is easy to generate, so that the waterproof layer of the rubber water stop belt on the outer side loses effect, and the leakage hidden danger is generated. Meanwhile, the buried rubber water stop belt is directly contacted with the concrete structure, and when structures on two sides of the reserved seam are unevenly settled, sharp stones in the concrete structure are easy to damage the buried rubber water stop belt, so that the leakage problem is caused. The utility model discloses the anti deformability of seam structure is reserved to the intention improvement basement, can adapt to the structural deformation of basement roof both sides and do not take place waterproof destruction.
