Construction method for embedding thermal insulation in concrete structure exterior wall surface

Abstract

The invention discloses a construction method of a concrete structure external wall with a built-in thermal insulating layer. The construction method comprises the steps of putting polystyrene plates among multiple layers of reinforcing meshes, obliquely inserting reinforcing steel bars in three-dimensional direction, welding the steel bars to obtain a thermal insulating wire rack board, and simultaneously pouring concrete on both internal and external sides to form a structural system. The specific construction method comprises the steps of: fabricating the thermal insulating wire rack board, banding external wall boundary members (embedded columns) and external wall board steel bars, installing the thermal insulating wire rack board, connecting steel bars around the thermal insulating wire rack board and laying pipelines, installing and fixing steel struts on the inner side of the thermal insulating wire rack board and cushion blocks on the outer side of the thermal insulating wire rack board, erecting inner templates for an external wall, erecting outer templates for the external wall, testing, simultaneously pouring concrete at both the internal side and the external side, removing templates, and curing. The inventive concrete structure external wall with the built-in thermal insulating layer has the advantages of solid connection, good sound insulating and thermal insulating effects, long service life, simple construction method, good shock resistant effect, short construction time, environmental friendliness, low construction cost, and good social and economic benefits; and is suitable for various urban residential buildings.

Description

1. Technical field: [0001] The invention relates to a building construction method, in particular to a construction method for a built-in insulation layer on the exterior wall of a concrete structure. 2. Background technology: [0002] Exterior wall insulation technology is widely used in current construction projects, but because the insulation layer is placed outside the structural surface, and it is mostly connected to the wall by bonding, due to the influence of natural conditions such as wind and sun, the insulation layer cannot It has the same service life as the wall structure layer, and quality problems such as cracking and peeling of the outer surface of the building often occur within the design service life, which does not achieve a good thermal insulation effect and affects the appearance. 3. Contents of the invention: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a constructio...
