Externally reinforced concrete irrigated and heat preservation wall structure embedded energy-saving system and its construction method

Abstract

The invention relates to an energy-saving system for a reinforced concrete outer-casting built-in heat insulation wall body structure and a construction method thereof, which can effectively solve the problems of external wall heat insulation of a high-rise building with high heat insulation requirement and cracking and falling of a heat insulation layer. The system is produced by a wall body and reinforcing steel bars in the wall body which are cast by concrete. The method comprises the following steps that: a reinforcing steel bar frame of the wall body is produced and arranged, namely parallel vertical reinforcing steel bars and indoor floor-connecting board tie bars perpendicular to the parallel vertical reinforcing steel bars are bound together, a grid board is hoisted and externally suspended outside the vertical reinforcing steel bars of the wall body, and is bound with the vertical reinforcing steel bars of the wall body by hooked bars and binding steel bars as well as framework positioning bearing bars, then a framework is arranged on the framework positioning bearing bars and is firmly bound with reinforcing steel bars of beams and boards of a floor, lapping bars are reserved, a heat insulation grid board is firstly arranged, then reinforcing steel bars of corbel brackets of a balcony and an air conditioning board external wall are bound, finally the concrete is cast, the curing is performed, and the framework is removed to repair the structure. The system has good heat insulation effect, energy conservation, environmental protection, simple method, and huge economic benefit and social benefit.

Description

1. Technical field [0001] The invention relates to the field of construction, in particular to an energy-saving system and a construction method for an externally cast reinforced concrete built-in thermal insulation wall structure energy-saving system. 2. Background technology [0002] With the development of science and technology and the improvement of people's material and cultural life, people's requirements for the living environment are getting higher and higher, especially for residential and office buildings. It is generally divided into external wall insulation, internal wall insulation composite wall insulation and self-insulation with thermal insulation materials. The thermal insulation effect inside the wall is not ideal, the construction period is long, the cost is high, and the quality cannot be guaranteed.

AI Technical Summary

Problems solved by technology

The thermal insulation effect inside the wall is not ideal, the construction period is long, the cost is high, and the quality cannot be guaranteed. The overall housing structure is limited to buildings with less than 8 floors; moreover, the main structural steel bars and thermal insulation grid bars are integrated by the factory, and the transportation and on-site installation are technically difficult, requiring professional equipment, high strength, and high cost ; At the same time, the on-site installation of grid slabs will increase the structural anchorage, and the cost of connecting steel bars will increase by 7-10 yuan / m 2 ;Structure design of different conventional construction drawings is required, the theoretical calculation is complex and highly professional; the design and processing of nodes, and the load bearing force of the entire outer wall protection layer mainly rely on diagonal tension bars (￠3, 100 pieces / m 2 ) transmission, there are hidden dangers in permanent security
