Embodiment Construction

[0050] The process steps of using the method of the present invention to construct the high-performance sand aerated concrete block wall are as follows:

[0051] 1. Construction preparation

[0052] (1) Select high-performance sand aerated concrete that meets performance requirements according to design requirements

[0053] The main technical performance indicators of block and high-performance sand aerated concrete block are shown in Table 5.2.1-1, and the block material should have a factory certificate and test report when entering the site. The construction site should be neatly stacked according to varieties, specifications and strength grades, and handled with care to prevent bumps and missing edges and corners. The ground of the stacking site should be flat, dry and rain-proof;

[0054] (2) Blocks should be stored for more than 15 days before leaving the factory, and the product age should not be less than 28d during masonry;

[0055] (3) The special adhesive for dr...

Abstract

The invention relates to the technical field of construction, and inparticular relates to a dry-method construction method for a high-performance autolaved aerated concrete block wall. The dry-method construction method comprises the following process procedures: performing construction preparation, positioning and paying off, leveling a wall foundation, erecting story poles, placing wall tie bars, constructing a block wall body, laying pipelines inside the wall body, mounting door/window hole cross beams, constructing outer wall concrete thermal bridge parts, constructing an outer wall waterproof interface agent, pasting special plaster putty on the inner wall in batch, constructing an inner wall finish coat layer, pasting wall surface heat-preservation blocks, and constructing a roof surface finish coat layer. The dry-method construction method is characterized in that a dry-method construction process is adopted for a blocking wall body, the part between the wall body and a beam top is filled with a polyurethane foamed adhesive, moreover a special construction method of an outer wall concrete thermal bridge part is adopted, the common quality problems of creep change of conventional masonry mortar and mortar joint cracks along wall surfaces are effectively solved, the overall property, the shock resistance and the heat-preservation property of the wall are improved, and the dry-method construction method can be widely applied to production construction of various buildings.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a dry construction method for a high-performance sand aerated concrete block wall. Background technique [0002] High-performance sand aerated concrete blocks are made of siliceous and calcareous materials as main raw materials, aluminum powder (aluminum paste) as foaming agent, advanced production process equipment, and high-pressure steam curing. The new wall material with porous structure, its main performance indicators such as appearance quality, dimensional deviation, thermal conductivity, etc. are better than the requirements of national standard superior products. High-performance sand aerated concrete blocks have the characteristics of light weight, heat preservation, heat insulation, fire resistance, waterproof performance and accurate product geometry; at the same time, they have the effects of sound insulation, shock resistance, energy saving and environ...
