Passive low-energy building external thermal insulation system construction process

Abstract

The invention discloses a passive low-energy building external thermal insulation system construction process that is different from an existing process described on the graph; the process comprises the following steps: laying warming plates into a thermal insulation wall, and building a reinforcement mat and casting same with the thermal insulation wall into one body. The single layer insulationstructure integrated technology firstly lays the thermal insulation wall, and then deploys the main structure steel bars; verticality control and template adjustment and calibration are fast.

Description

technical field [0001] The invention belongs to the field of building thermal insulation materials, in particular to a construction process of a passive low-energy building external wall thermal insulation system. Background technique [0002] Low-energy buildings refer to buildings that adapt to climate characteristics and natural conditions, and adopt high-efficiency fresh air heat recovery technology to minimize the cooling demand of buildings and make full use of renewable energy through enclosure structures with higher thermal insulation performance and airtight performance , A building that provides a comfortable indoor environment with less energy consumption and meets the basic requirements of green buildings. [0003] One of the key technologies for low-energy buildings is high-efficiency thermal insulation of the enclosure structure. At present, the construction industry mainly adopts double-layer or single-layer insulation board post-attachment construction techno...

Problems solved by technology

[0009] However, these methods are only suitable for thinner insulation boards

like figure 1 As shown, it is a schematic diagram of the construction process of the existing cast-in-place concrete composite thermal insulation system with thermal insulation composite panels. It can be seen from this that the existing integrated technology generally binds the main structural steel bars first, and then arranges the thermal insulation panels. In view of the thickness required for low-energy buildings It is thicker than the traditional thickness, generally up to 300mm, which is equivalent to a "light masonry wall". It has good integrity and is not conducive to the adjustment of the distance between the inner and outer formwork cavities
