Embodiment Construction

[0019] Such as figure 1 As shown, the autoclaved aerated concrete block wall self-insulation system construction technology of the present invention has included the following steps:

[0020] The first step: construction preparation

[0021] 1. Sprinkle water on the block masonry surface 1-2 times 2 days before masonry. The moisture content of the upper wall of the block should be 10%-15%, and the surface immersion depth should be 8-10mm.

[0022] 2. Special tools should be used for sawing blocks. Axes or tile knives are not allowed to chop at will. In order to reduce the workload of on-site sawing during construction, avoid waste, and facilitate material preparation, the arrangement of blocks should be designed before masonry.

[0023] 3. Air-entrained concrete of different densities and strength levels should not be mixed, and blocks from different manufacturers should not be mixed. Air-entrained concrete blocks should not be mixed with other bricks and blocks. Partial use...

Abstract

The invention discloses a construction process for a self-heat-insulation system of an autoclaved aerated concrete block wall. A wall building process is subjected to three necessary technical slot time, namely the time from building and walling of autoclaved aerated concrete blocks to curing lasts for at least 28 days; reserved clearances between the top of the autoclaved aerated concrete block wall and a beam and between the top and a board, namely rear blocking ports can be supplementarily built after at least seven days at interval; and the time from completion of the autoclaved aerated concrete block wall to wall plastering lasts for at least 30 days. By adopting the three necessary technical slot time, the construction surface is fully dried, thus greatly reducing the internal stress of materials due to drying shrinkage deformation and temperature change of the material and preventing crack and leakage of the wall. In addition, an inorganic heat-insulation material or aerated concrete blocks are used for heat insulation at the thermal bridge positions of reinforced concrete walls, posts and beams of outer walls according to thermotechnical calculation, thus eliminating thermal bridges and meeting the energy-saving requirement.

Description

technical field [0001] The invention relates to a construction method for filling wall masonry, in particular to a construction process for an autoclaved aerated concrete block wall self-insulation system. Background technique [0002] Autoclaved aerated concrete block is a new energy-saving self-insulation material recommended by the Ministry of Construction. It has light bulk density, low thermal conductivity, good thermal insulation effect, high fire resistance, strong stability, and can last the same life as the building. With the advantages of high efficiency, safety and environmental protection, it can meet the requirements of building energy conservation with a single material. At present, the autoclaved aerated concrete self-insulation system with good thermal insulation performance, waste utilization and environmental protection is vigorously promoted, which meets the requirements of building energy-saving, economical and applicable safety technology routes.
