Construction method for high-ductility heat-insulating masonry wall

Abstract

The invention discloses a construction method for a high-ductility heat-insulating masonry wall. The method comprises the following steps: according to a design size of the cross section of the masonry wall, smearing a layer of high-performance masonry mortar on a position where the masonry wall is needed; paving building blocks on the high-performance masonry mortar, and smearing the high-performance masonry mortar, according to a design height of the masonry wall, completing the masonry of the wall, and curing for 7 days so that the wall reaches the initial strength; smearing a high-performance cement-based material on the surface of the completed masonry wall, and laying a fiber weaving net on the high-performance cement-based material, and smearing the high-performance cement-based material on the fiber weaving net, wetting and curing for 28 days until reaching an age of the high-performance cement-based material; and smearing polymer adhesive mortar on the high-performance cement-based material at one side, contacting with an outside natural environment, of the masonry wall, and laying a heat-insulating board on the polymer adhesive mortar, finally smearing decoration mortar on the heat-insulating board. The method is capable of effectively improving the ductility of the newly constructed masonry wall, reducing a risk that the masonry structure is seriously damaged,even collapsed, in an earthquake, effectively improving the heat-insulating performance of the newly constructed masonry wall, and reducing the construction energy consumption of the masonry wall.

Description

technical field [0001] The invention relates to a masonry wall and a construction method thereof, in particular to a construction method of a masonry wall with high ductility and thermal insulation performance. Background technique [0002] For a long time to come, masonry structures will still occupy an important position in my country's industrial and civil buildings. As a component material of masonry structure, masonry is made of blocks and mortar. Due to the influence of material properties and composition, masonry has high discreteness and randomness, and its heterogeneity is stronger than that of concrete. High, belonging to typical brittle materials. The results of the earthquake damage investigation show that, as the main bearing member of the masonry structure, the masonry wall will severely crack or even collapse in the earthquake, resulting in the most serious damage to the masonry structure in previous earthquakes. The ductility of the body wall is poor. At t...
