Construction method of external thermal insulation system of foam cement thermal insulation board outer wall

Abstract

The invention discloses a construction method of an external thermal insulation system of a foam cement thermal insulation board outer wall. The construction method comprises the steps that first, thermal insulation boards are laid, specifically, a thermal insulation board laid layer which is formed by splicing the foam cement thermal insulation boards is laid on a building outer wall; second, holes in the outer sides of a door and a window are reinforced, and the bottom of a middle-upper laid area, the top of a lower laid area and the inner sides of two side laid areas in the thermal insulation board laid layer are all covered with fiberglass gridding cloth to form a gridding cloth reinforcing layer; third, plastering construction is conducted, specifically, plastering construction comprises the processes of 301 primary rendering coat mortar coating construction and fiberglass gridding cloth pasting, 302 secondary rendering coat mortar coating construction and fiberglass gridding cloth pasting, and 303 plastering treatment of the holes in the outer sides of the door and the window; and fourth, finishing construction is conducted, specifically, finishing construction comprises the processes of 401 putty layer construction and 402 finishing coating construction. The construction method of the external thermal insulation system of the foam cement thermal insulation board outer wall is simple in step, reasonable in design, convenient to construct, good in using effect, capable of completing the construction process of the external thermal insulation system of the foam cement thermal insulation board outer wall easily and capable of guaranteeing the construction quality.

Description

technical field [0001] The invention belongs to the technical field of construction of an external thermal insulation system for an external wall of a building, and in particular relates to a construction method for an external thermal insulation system of an external wall of a foamed cement thermal insulation board. Background technique [0002] With the rapid development of the construction industry, the innovative application of building insulation materials is also very extensive. Building thermal insulation materials in the external wall insulation system must not only meet the thermal insulation performance requirements, but also meet the national standards for fire protection. Foamed cement insulation board (also known as cement foam insulation board or foam concrete insulation board), as a new type of building insulation material, not only meets the requirements for thermal insulation performance, but also has a fire rating that meets the national A-level standard.

Problems solved by technology

[0004] Nowadays, in the construction process of the external wall external insulation system of foamed cement insulation board, there is no unified, standardized and specific construction method to follow, so it is inevitable that the construction operation is relatively random, irregular, and construction efficiency is low during actual construction. , poor construction quality and many other problems
