Problems solved by technology

[0002] In the prior art, the insulation material between the inner and outer two-layer leaf walls of the sandwich insulation wall is usually a prefabricated insulation board. When the wall is built on site, the insulation board is inserted into the cavity between the inner and outer two-layer leaf walls. Yes, first of all, the energy consumption of prefabricated thermal insulation materials in the factory not only does not comply with the national policy of energy conservat

Embodiment Construction

[0018] There is a drill hole (3) at the mortar joint of any leaf wall of the inner and outer leaf walls (1) or (2), through which the hole is injected into the cavity between the inner and outer leaf walls Insulation foam material.

[0019] The thermal insulation foaming material is urea-formaldehyde foaming material or polystyrene foaming material or nitrogen urea foaming material or polyurethane foaming material.

[0020] At least one leaf wall of the two inner and outer leaf walls is made of non-load-bearing hollow blocks.

[0021] The load-bearing blocks are solid bricks or hollow bricks.

[0022] Boreholes (3) are inspection holes (6) and / or pouring holes (5).

[0023] The positions of the pouring holes (5) are at 1 / 4 and 3 / 4 of the height of each floor wall, and the thermal insulation material is poured into the cavity between the inner and outer leaf walls on-site by spray guns.

[0024] Inspection holes (6) are located at 1 / 2 of the wall height and / or at the bottom ...

Abstract

The invention relates to sandwich heat-preservation wall and a construction method thereof. The heat-preservation wall consists of two layers of cavity wall which is brick-built by the internal and the external layers of masonry blocks; the heat-preservation layer is formed by insulation material by spot foaming. The insulation foaming material can be urea formaldehyde foaming material or polystyrene foaming material or urea nitrogen foaming material or polyurethane foaming material. The sandwich heat-preservation wall can improve wall heat-preservation performance, decrease production procedure, reduce production cost and waste, and meet the environment protection requirement for saving energy and reducing emissions.

Description

technical field [0001] The invention relates to heat preservation of external walls, in particular to a structure and a construction method of a sandwich heat preservation wall. Background technique [0002] In the prior art, the insulation material between the inner and outer two-layer leaf walls of the sandwich insulation wall is usually a prefabricated insulation board. When the wall is built on site, the insulation board is inserted into the cavity between the inner and outer two-layer leaf walls. Yes, first of all, the energy consumption of prefabricated thermal insulation materials in the factory not only does not comply with the national policy of energy conservation, emission reduction and environmental protection, but also there will inevitably be a lot of defective products in the production process, which will cause waste of materials. Secondly, insulation boards will inevitably appear during transportation. The breakage and breakage of the wall, again, the insula...
