Construction method for net-free cast-in-place polystyrene board heat insulation system

Abstract

The invention discloses a construction method for a net-free cast-in-place polystyrene board heat insulation system. The construction method sequentially comprises the following steps that the two sides of a polystyrene board are sprayed with interface mortar before casting of a formwork; the polystyrene board is cut according to the shape of a building and installed; anti-crack mortar is evenly smeared on the surface of the polystyrene board, and a cut alkali-resisting gridding cloth is immediately pressed into the anti-crack mortar with an iron plaster trowel; and after the anti-crack mortaris dried, a hot-dip galvanized welded wire mesh is fixed. By means of the construction method for the net-free cast-in-place polystyrene board heat insulation system, the problems that in the prior art, the external wall surface, especially the external wall surface of an old building, is damaged in external environment, the bodies of residents are influenced, and the warming and cooling cost isalso greatly increased are solved, when the construction method for the net-free cast-in-place polystyrene board heat insulation system is applied, the outer surface of the building can be wrapped forprotection, and the service life of the building is greatly prolonged while the heat insulation of the building is achieved. The built wall heat insulation system is the best external wall protectionsystem of a new building, and is also a best maintaining system of an old building.

Description

technical field [0001] The invention relates to heat preservation of polystyrene boards, in particular to a construction method of a netless cast-in-place polystyrene board heat preservation system. Background technique [0002] In the prior art, the outer wall is used as the outer layer of the building, which must withstand the influence of all external climates, such as heat, cold, freezing, snow, hail, rain and wind. Rainwater, temperature changes, and environmental pollution alternately and continuously act on the exterior wall, causing cracks and mold to form on the exterior wall. Buildings were damaged, occupants were physically affected, and heating and cooling costs were dramatically increased. Compared with the expensive building maintenance costs, the value of the external wall thermal insulation system is much higher than its own cost. It "wraps" and protects the exterior of the building. While meeting the thermal insulation performance of the building, it greatl...

Problems solved by technology

[0003] The invention solves the problems existing in the prior art that the outer walls, especially the outer walls of old buildings, are damaged in the external environment, the body of the occupants is affected, and the cost of heating and cooling is also greatly increased. The construction method of the polystyrene board thermal insulation system can "wrap" and protect the exterior of the building when it is applied, which greatly prolongs the life of the building while satisfying the thermal insulation performance of the building
