Description

Near zero energy consumption building indoor ground movement joint airtight construction device Technical Field The invention relates to the technical field of building energy conservation, in particular to an airtight construction device for an indoor ground deformation joint of a near-zero energy consumption building. Background Along with the continuous improvement of building energy-saving standards, near-zero energy consumption buildings become an important direction of building development in China. The overall air tightness of the building is one of the core technical characteristics of near-zero energy consumption building, the good air tightness can effectively reduce cold and hot loads caused by cold air permeation in winter and uncontrolled ventilation in summer, the energy consumption of heating and air conditioning of the building is obviously reduced, and the building is a necessary premise for achieving the near-zero energy consumption. In indoor building construction, floor deformation joints are necessary construction joints provided for adapting to temperature deformation, settlement deformation and earthquake displacement of the building structure. However, the deformation joint penetrates through the floor, so that a potential channel for indoor and outdoor air exchange is formed, and the airtight node treatment effect directly influences the standard of the overall airtight performance of the building. Therefore, the airtight structural design of the deformation joint is an important point and a difficult point of the airtight design of the near-zero energy consumption building envelope. At present, the Chinese patent with publication number of CN109267709B and publication date of 2019, 01 and 25 proposes a deformation joint anti-leakage structure and a repairing method thereof, wherein the deformation joint anti-leakage structure comprises a multi-layer sealing anti-leakage structure, an elastic filling material, a sealing paste filling layer, a flexible waterproof material layer, a pressing strip and a structural layer main body, wherein a first-layer sealing is formed through the elastic filling material and the sealing paste, a second-layer sealing is formed through fixing the flexible waterproof material layer and the pressing strip, and a water stopping groove and sealing glue are combined. The deformation joint is ensured not to damage the sealing performance during deformation. Aiming at the related technology, because the indoor ground needs to be cleaned and maintained daily, including activities such as water drying and mopping, water vapor is easy to permeate into the deformation joint through the joint or capillary action of the surface layer material. After the traditional flexible waterproof material layer is wetted for a long time, deterioration phenomena such as mildew, chalking, strength attenuation and the like are easy to occur, so that the airtight performance of the traditional flexible waterproof material layer is obviously reduced and even completely fails, and the severe requirements of indoor airtight performance for a long time, stability and reliability can not be met.
