Description

Waterproof type building indoor floor deformation joint structure

Technical Field

The utility model relates to a building movement joint structure, more specifically say, relate to a waterproof type building indoor floor movement joint structure.

Background

Due to the influence of temperature variation, uneven settlement, earthquake and other factors, additional stress is generated inside the building structure, and the stress often cracks or even damages the building. In order to reduce the influence of stress on the building, the structure is broken at the deformation sensitive part in advance during design, and a gap, namely a deformation joint, is reserved so as to ensure that each broken part of the building has enough deformation space and not to damage the building or generate cracks. According to different design concepts, the deformation joint is divided into an expansion joint, a settlement joint and a shockproof joint. The deformation joint reduces deformation cracks which are difficult to process in a plurality of projects, ensures the safety of the structure, and brings adverse effects to the use of the building if the structure of the joint is not properly processed. For example, in floors where waterproofing is required, the deformation joints are difficult to waterproof, and the deformation joints cannot meet the finishing requirements of the floor, and the normal use of the floor is affected by the oversize of the members.

With the continuous development and progress of society, people not only have a constant demand on the buildings, but also have higher requirements on the comfort and the delicacy of the buildings. The design of the deformation joint is an important component in the building design, whether the design is reasonable or not directly influences the normal use of the building and the beauty of the building, and sufficient attention should be paid in the design. However, in many projects at present, deformation joint treatment is not reasonable and satisfactory, and waterproof treatment of the deformation joint is not in place, so that problems of water leakage of floors and the like are caused, and the problem becomes a pain point problem of building deformation joints. As for the waterproof treatment technology of deformation joints, there are also related technical schemes, such as a water leakage prevention building structure applied to floor deformation joints disclosed in chinese patent No. ZL201620633150.0 and a waterproof and drainage combination floor deformation joint waterproof structure and construction method disclosed in chinese patent application No. 201611239971.7. The above patent application waterproof the deformation joint by the waterproofing membrane, but its deformation joint member can not prevent water leakage completely, for this reason also need design drain tank and drain pipe in the deformation joint structure, be used for the ponding drainage that the waterproofing membrane collected. However, the waterproof structure has a complex structural design, the drainage grooves and the drainage pipes are difficult to lay, parts needing sealing are added, and the waterproof effect is not ideal; and the inside ponding of waterproof construction easily leads to inside moldy scheduling problem, and the clearance is difficult.

Therefore, it is of positive practical significance to discuss a reasonable and durable indoor floor waterproof deformation joint structure.
