Problems solved by technology

Although it does not pose a structural safety risk, if it is a crack in the outer wall, it will easily cause leakage, which will seriously affect the normal use of the residents, and it will be difficult to maintain; especially for high-rise buildings, the wind pressure on the outer wall is large. , is strongly affected by wind and rain, and other continuous quality or safety accidents may occur after leakage

Embodiment 1

[0030] A construction method for preventing cracks in a filling wall, the filling wall includes an inner wall and an outer wall, and is characterized in that it includes the following steps:

[0031] a. Filling wall masonry, the inner wall is built with 190mm thick lightweight aggregate concrete small hollow blocks, the outer wall is built with sintered coal gangue porous bricks, and the size and thickness of the blocks are consistent with the thickness of the shear wall to avoid The thickness of the plastering layer on both sides of the subsequent transfer of different materials is inconsistent; Mb7.5 cement mortar or Mb7.5 cement mixed mortar with medium coarse sand should be used for masonry mortar, and mountain sand should not be used, and the mud content of the sand should be controlled below 5%. ; The mortar consistency is 50-80mm, and the mortar layering degree is 10-30mm; the bulk density of inner wall blocks is 1000kg / m 3 Below, the bulk density of external wall block...

Abstract

The invention relates to a construction method for preventing crack of an infilled wall. The infilled wall comprises an inner wall and an outer wall. The method is characterized by comprising the following steps of: a, constructing the infilled wall; b, embedding a tie bar; c, suspending a hot dip galvanizing steel wire gauze; d, spraying bonding agent; e, paving fiberglass mesh; f, plastering mortar in a layering way; g, coating and polishing a putty layer; and h, painting paint, wherein the paint adopts emulsion paint which can be different according to design requirements and is painted for three times by a brush. The construction method for preventing crack of the infilled wall has the advantages that: the construction steps are reasonable in design, simple in operation, and safe and reliable in construction quality; and the infilled wall has no delaminating, hollowing, ash blasting or cracking.

Description

technical field [0001] The invention relates to a construction method for a building wall, in particular to a construction method for preventing cracks from being filled in the wall. Background technique [0002] Masonry materials are an important part of building materials. Due to the needs of environmental protection and energy saving, masonry materials have changed from traditional clay bricks to concrete hollow blocks, fly ash aerated silicate blocks, and aerated concrete blocks. And other new wall materials, in various forms. When masonry works with concrete, cement mortar and other materials, the drying shrinkage deformation values ​​vary greatly, and some even differ by several times, and cracks are prone to occur during long-term work. Cracks in masonry filled walls are deformation cracks, which are mainly caused by temperature, drying shrinkage and other reasons. Although it does not pose a structural safety risk, if it is a crack in the outer wall, it will easily...
