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

Abstract

The invention relates to an exterior wall insulation construction method of composite cast-in-site concrete with non-reinforcing mesh polystyrene board, which can effectively solve the problems of the exterior walls with high quality, high speed, and low cost in the construction. The exterior wall insulation construction method is characterized in that: a flame retardant polystyrene board with concave and convex tooth sockets on one surface serves as the thermal insulation material for the cast-in-site concrete exterior wall; steel bars of the wall body are bundled; the polystyrene board is arranged on the outer side of the bundled steel bars of the wall body; an insulation board and a formwork are installed; the polystyrene board is penetrated by clips of the polystyrene board; the clips and the steel bars of the wall body are bundled and fixed by bundled iron wires; after the concrete is cast, dovetail grooves of the polystyrene board are fixedly combined with the concrete; after the formwork is removed, maintenance is carried out, and then repair and leveling are conducted through gelatin powder; after an anti-crack protection layer is coated and exterior wall putty is scraped, coating is made or face bricks of the exterior wall are constructed, so as to improve the application effect. As the polystyrene board and wall body are fixedly combined as a whole for once, the existing surface-sticking process for the insulation board and the wall body is omitted, thereby the construction procedure is reduced, the construction period is shortened, and the economic and social benefits are great.

Description

1. Technical field [0001] The invention relates to the construction field, in particular to a construction method for thermal insulation of cast-in-place concrete external walls with a netless polystyrene board. 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 improving the quality of the indoor thermal environment and the q...

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 quality, high speed and low cost of external wall construction, and the technical solution for it 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 wall reinforcement, place the polystyrene board on the outside of the bound exterior wall reinforcement, install the insulation board and For the formwork, use polystyrene board clips (or nylon anchor bolts) to penetrate the polystyrene board, and tie the clips to the 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 template is maintained, it is repaired and leveled with rubber powder, and the anti-crack protective layer is applied. After scraping the putty on the external wall, paint or paste external 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 process of pasting the insulation board and the wall, reduces the construction process, greatly shortens the construction period, and has huge economic and social benefits
