Embodiment

[0026] 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.

[0027] 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;

[0028] 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;

[0029] Then mix material A and material B evenly and spray it to the inner surface quickly. The foaming time is 20-30s, and the thicknes...

Abstract

The invention provides a construction method of a foamed polyurethane thermal insulation layer, and belongs to the field of building construction. The construction method particularly comprises the following steps of 1, manufacturing an outer plate; 2, manufacturing a fixing device; 3, manufacturing a pre-spraying outer plate; 4, pouring on site; and 5, sealing seams. According to the method, a hook connecting rod is used to fix the outer plate is fixed to a wall body on the premise that the wall body is not damaged, polyurethane is poured into a cavity formed by the outer plate and the wall body in a stacked mode, pressure force brought by foaming deformation of the polyurethane is buffered and borne by flexible foam polyurethane pre-sprayed on the outer plate, the outer plate is light and thin, selectable materials are rich, a wall is not damaged in the construction process, construction is easy, so that method is particularly suitable for high-rise operation.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an on-site construction method of a large-area polyurethane thermal insulation layer. Background technique [0002] In the north, it is very cold in winter, and a layer of insulation layer is generally constructed on the outside of the wall. Generally, rock wool board is used as the insulation material, and it is transported to the construction site and then veneered for construction. The rock wool is thick, and there is a certain degree of difficulty in lifting high-rise construction. [0003] After technological reform, now high-end residential buildings mostly use polyurethane (polyurethane) which is lighter and has better thermal insulation performance as the insulation layer material. Firstly, polyurethane foam boards are made in the building material factory, and then transported to the site for placement. There are still the following problems: 1. The adh...
