Non-net polyphenyl plate cast-in-place concrete exterior wall heat-preserving construction method

Abstract

The invention relates to a construction method for thermal insulation of cast-in-place concrete external walls with non-network polystyrene boards, which can effectively solve the problems of good construction quality, high speed and low cost of external walls. The polystyrene board is used as the thermal insulation material of the cast-in-place concrete exterior wall, the wall reinforcement is bound, the polystyrene board is located on the outside of the bound exterior wall reinforcement, the insulation board and formwork are installed, and the polystyrene board clips are used to penetrate the polystyrene board. The board is bound and fixed with the steel bar of the wall by binding iron wire. After the concrete is poured, the dovetail groove of the polystyrene board is firmly combined with the concrete. Layer, after scraping the putty on the external wall, paint or paste the external wall bricks to improve the use effect. The polystyrene board and the wall are firmly integrated into one, which survives at one time, eliminating the past paste process of the insulation board and the wall, reducing construction The process shortens the construction period, and the economic and social benefits are huge.

Description

1. Technical field [0001] The invention relates to the field of construction, in particular to a thermal insulation construction method for cast-in-place concrete exterior walls with polystyrene boards. 2. Background technology [0002] In recent years, with the rapid development of urban construction, people's living standards have been continuously improved, and people have become more and more yearning for a comfortable living environment, especially the desire to buy residential houses. At present, real estate is in a booming period, and construction There are more and more buildings, so the requirements for building energy-saving standards are getting higher and higher. In order to improve the operating efficiency of heating, cooling, lighting, ventilation, water supply and drainage, and passages, as well as the use of renewable energy, in order to ensure the use of buildings Under the premise of environmental protection and indoor thermal environment, external wall ins...

AI Technical Summary

Problems solved by technology

[0004] In view of the above situation, the purpose of the present invention is to provide a new thermal insulation construction method of cast-in-place concrete external wall with no mesh polystyrene board, which can effectively solve the problems of good construction quality, high speed and low cost of external wall, and its technical solution Yes, use a flame-retardant polystyrene board with concave-convex grooves on one side as the insulation material for the cast-in-place concrete exterior wall, bind the external wall reinforcement, place the polystyrene board on the outside of the bound external wall reinforcement, and install the polystyrene board and formwork, use polystyrene board clips (or nylon anchor bolts) to penetrate the polystyrene board, and bind the clips to the external wall steel bars by binding iron wires. After pouring concrete, the dovetail groove of the polystyrene board is firmly combined with the concrete. After the formwork is removed, it is maintained, and then repaired and leveled with rubber powder. After the anti-crack protective layer is scraped and putty on the outer wall, paint or paste the outer wall bricks to improve the use effect. The polystyrene board and the wall are firmly integrated. One-time survival, the whole process saves time and effort, saves the previous polystyrene board and wall pasting process, reduces the construction process, greatly shortens the construction period, and has huge economic and social benefits
