Construction method of self-insulating autoclaved sand aerated concrete masonry combined with inorganic insulation mortar

Abstract

The invention relates to a construction method of combining self-thermal insulation autoclaved aerated concrete blocks with an inorganic thermal insulation mortar. A self-thermal insulation block wall is build between reinforced concrete walls on the two sides and formed by laying the self-thermal insulation autoclaved aerated concrete blocks, wherein the length of the block is L; in the odd layers of blocks, the length of the head block and the tail block is less than L; in the even layers of blocks, gaps in the inner side surfaces of the head block and the tail block have the same length of the head block and the tail block in the odd layers of blocks; a gap is formed among the head block and the tail block of each layer of the blocks and the reinforced concrete wall and filled with soft stuff; the inner side surface of the reinforced concrete wall is coated with a cracking-resistance thermal-insulation layer, and the gaps, the inner side surfaces of the head blocks and the tail blocks of the odd layers of blocks and notches of the head blocks and the tail blocks of the even layers of blocks are also coated with the cracking-resistance thermal-insulation layer. The contraction deformation difference between the reinforced concrete wall and the self-thermal insulation wall is coordinated, so that thermal bridge portions are closely combined with the self-thermal insulation wall to form a whole body, wall cracking is prevented, and thermal insulation performance is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method of self-insulating autoclaved sand aerated concrete masonry combined with inorganic insulating mortar. Background technique [0002] At present, the energy-saving building envelope structure adopting wall self-insulation system is generally composed of load-bearing reinforced concrete walls, columns and non-load-bearing autoclaved sand aerated concrete masonry walls. The physical and mechanical properties of reinforced concrete, autoclaved sand aerated concrete blocks, masonry mortar and other materials are different in terms of compressive tensile strength, drying shrinkage, thermal conductivity, etc., such as: autoclaved sand aerated concrete blocks The thermal conductivity is smaller than that of reinforced concrete walls, while the compressive tensile strength and drying shrinkage of autoclaved sand aerated concrete blocks are worse than those of rei...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly solves the problem that the original "thermal bridge" treatment scheme of embedded concrete walls and columns in the self-insulating exterior wall cannot effectively coordinate the shrinkage and deformation differences of different wall materials, resulting in the formation of reinforced concrete walls, columns and self-insulating walls at the junction. The thermal bridge part is prone to cracking and thermal insulation failure technical problems; provide a self-insulating autoclaved sand aerated concrete masonry combined with inorganic thermal insulation mortar construction method, which can coordinate the shrinkage between reinforced concrete walls, columns and self-insulation walls The difference in deformation makes the thermal bridge part and the self-insulating wall tightly integrated into a whole, prevents the wall from cracking, ensures thermal insulation performance, and the construction process is relatively simple, reducing construction safety hazards and saving procurement costs
