PVC (Polyvinyl chloride) protective corner technology for external corner in heat preservation construction of exterior wall

Abstract

The invention provides a PVC (Polyvinyl chloride) protective corner technology for an external corner in heat insulation construction of an exterior wall. The technology comprises the following steps of laying a finished PVC protective corner with double-wing mesh cloth at each position of external corners, such as large external corners, windows, cornices and holes, of a wall surface before surface mortar is plastered on the exterior wall for heat insulation for the last time; arranging a through line at each external corner position; firstly plastering rendering putty on the bottom layer, adjusting the protective corner installation position according to the through line, pressing the double-wing mesh cloth, then plastering wall surface putty and pressing glass fiber mesh cloth, and plastering the surface mortar for the last time. The PVC protective corner technology for the external corner in the heat insulation construction of the exterior wall has the advantages that the heat insulation quality and acceptance check of the exterior wall conform to standard error requirements, the sealing property and safety of the exterior heat insulation system of the exterior wall are improved, and the durability of the exterior heat insulation system of the exterior wall is guaranteed; meanwhile by utilization of the protective corner, the construction speed is increased, the construction period can be shortened, the labor cost is reduced, the construction cost is reduced, the impact resistance of the external corner is improved, a wall corner is effectively prevented from being damaged, the appearance quality is improved, the construction quality is improved, and the service life of the exterior wall for heat insulation is prolonged.

Description

technical field [0001] The invention belongs to the field of external wall thermal insulation construction, and in particular relates to a PVC corner protector process for external wall thermal insulation construction. Background technique [0002] The exterior walls of buildings are usually treated with thermal insulation. Due to factors such as the quality of workers and construction conditions, the construction quality of exterior wall insulation construction is uneven, making it difficult to guarantee the thermal insulation effect and sensory quality of exterior walls. The external wall insulation construction requires the positive and negative angles to be ±3mm, and the verticality ±3mm. However, in actual construction, it is difficult to ensure the construction error allowed by the code, resulting in unqualified construction quality. Contents of the invention [0003] In view of this, the present invention aims to propose a PVC corner protector process for external w...

Problems solved by technology

[0002] The exterior walls of buildings are usually treated with thermal insulation. Due to factors such as worker quality and construction conditions, the construction quality of exterior wall insulation construction is uneven, which makes it difficult to guarantee the thermal insulation effect and sensory quality of the exterior walls.

The external wall insulation construction requires the positive and negative angles to be ±3mm, and the verticality ±3mm, but it is difficult to guarantee the construction error allowed by the code in actual construction, so the construction quality is unqualified.
