Problems solved by technology

[0004] There are still the following problems: 1. The adhesion between the polyurethane foam board and the wall is poor, and high-strength adhesive needs to be applied additionally; 2. The high-rise patch still needs the cooperation of a crane; 3. There are gaps between the sheets, and the entire insulation layer is not As a whole, subsequent potting treatment and reinforcement are required
This leads to on-site construction, especially high-rise operations that require the cooperation of cranes. At the same time, in order to fix the heavy outer panels, the fixing devices often use drilling rods and other methods. The subsequent removal is time-consuming and laborious, and damages the wall.
[0006] What's more, the polyurethane insulation layer is not resistant to high temperature, and the optimal fire protection level is B class, which will produce toxic gas after burning. Therefore, 100% polyurethane insulation material is used, and it is difficult for high-rise buildings to meet the national fire protection regulations.

Embodiment

[0028] The following is the specific construction method of the present invention, which is not a limitation to the claims. Changes made by those skilled in the art based on the relevant knowledge in the field are also within the protection scope of the present invention.

[0029] The plate used in the present invention is a PVC exterior wall hanging plate, the combustion performance is B2 level, and the thickness is 6mm;

[0030] For buildings in Jinan (North) area, according to the construction requirements, a layer of 30cm thick insulation layer needs to be constructed on the outer wall of the six-storey building. After the building material processing factory produces the 1.0m*1.0m outer panel, the four front-end protruding connecting rods are bonded At the four corners of the outer plate, the end without protrusions is the bonding end;

[0031] Then mix polyurethane material A and material B evenly and spray it to the inner surface quickly, the foaming time is 10-20s, the...

Abstract

The invention provides a composite insulating layer construction method, and belongs to the field of building construction. The method particularly comprises the following steps of 1) manufacturing anouter plate; 2) manufacturing a fixing device; 3) manufacturing an asbestos-foamed polyurethane outer plate; 4) pouring on site; 5) sealing seams. A hook connecting rod is used, and the outer plate is fixed to a wall body on the premise that the wall body is not broken. During on-site construction, polyurethane is poured into a cavity formed by the fixed outer plate and the wall body in a stackedmode, and a compression force brought by foaming deformation of the poured polyurethane is borne by flexible foam polyurethane of the asbestos-foamed polyurethane outer plate. In the constructed insulating layer, the polyurethane is separated by asbestos, and the fireproof capacity of the insulating layer is improved. The adopted outer plate is light and thin, selectable materials are rich, the wall body is not damaged in the construction process, construction is convenient, and the national fireproof requirement is met.

Description

technical field [0001] The invention belongs to the field of building construction methods, and in particular relates to a construction method for a composite thermal insulation outer layer. Background technique [0002] In the prior art, asbestos or polyphenylene is mostly used as insulation materials for building exterior walls, which can only be processed and produced in construction factories and then transported to the construction site for pasting. The insulation boards are bulky, and high-rise buildings need lifting cooperation for pasting. And the insulation effect is poor. [0003] In recent years, due to technological progress, polyurethane insulation has become popular in a large area. It is light in weight and can be constructed on site, saving transportation costs. Moreover, the insulation effect of polyurethane insulation is better than that of asbestos board or polystyrene board. Under the same insulation effect of external walls, asbestos Or polystyrene boar...
