Manufacturing method and structure for basement floor without crack, leakage and with oversized area

Abstract

The invention discloses a manufacturing method and a structure for a basement floor without crack, leakage and with an oversized area. According to the method and the structure, disclosed by the invention, a concrete self waterproof floor board layer is firstly poured, and the concrete self waterproof floor layer is poured by adopting leakage resisting concrete; a drain board layer made from high impact polystyrene (HIPS) is paved on the concrete self waterproof floor board layer; then, a plain concrete leveling layer is poured on the drain board layer; a reinforced concrete layer of which the thickness is from 160 to 260mm is poured on the plain concrete leveling layer, the reinforced concrete layer is divided into small integrated reinforced concrete layers by expansion joints, and extruded polystyrene board materials are filled in the expansion joints; a polyurethane coating layer is painted on each small integrated reinforced concrete layer of the reinforced concrete layer, and silicone weather-proof glue is filled in a gap between every two adjacent polyurethane coating layers. The structure has the advantages of difficulty in sinking, no crack, no leakage and the like.

Description

technical field [0001] The invention relates to a method and structure for making a super large-area basement floor without cracks and leakage, and belongs to the technical field of making super-large-area basement floors. Background technique [0002] There are relatively mature construction techniques for the construction technology of large-area fine stone concrete floors at home and abroad. However, at present, when using the existing technology to construct a super-large-area floor (the area of ​​the floor is ≥ 10,000 square meters, it is a super-large-area floor), especially when using the existing technology to construct a super-large-area basement floor, it is very difficult. It is prone to quality problems such as floor subsidence, irregular cracking of the floor, serious floor leakage, large deviation of floor surface flatness, and short service life of the floor. Therefore, the manufacturing method of existing super large area basement floor is still not ideal en...

Problems solved by technology

However, at present, when using the existing technology to construct a super-large-area floor (the area of ​​the floor is ≥ 10,000 square meters, it is a super-large-area floor), especially when using the existing technology to construct a super-large-area basement floor, it is very difficult. It is prone to quality problems such as floor subsidence, irregular cracking of the floor, serious floor leakage, large deviation of floor surface flatness, and short service life of the floor.

Therefore, the manufacturing method of existing ultra-large area basement floor is still not ideal enough.
