Manufacturing method and structure of super large area basement floor without cracks and leakage

Abstract

The invention discloses a non-crack, non-leakage super large-area basement floor production method and structure, The present invention first pours a layer of concrete self-waterproof floor, and the concrete self-waterproof floor is poured with impermeable concrete; a layer of high-impact polystyrene is laid on the concrete self-waterproof floor (HIPS) Drainage slab layer made of materials; then pour a layer of plain concrete leveling layer on the drainage slab layer; pour a layer of plain concrete leveling layer with a thickness of 160 ～ 260 mm thick reinforced concrete layer, and the reinforced concrete layer is divided into small monolithic reinforced concrete layers through expansion joints, and extruded polystyrene board materials are filled in each expansion joint; and then in each reinforced concrete layer A layer of polyurethane coating is painted on the small monolithic reinforced concrete layer, and silicone weather-resistant adhesive is filled in the gap between every two adjacent polyurethane coatings. The invention has the advantages of not easy to sink, 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.
