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 for a foamed polyurethane insulation layer, which belongs to the field of building construction. Specifically, it is carried out through the following steps: 1) making an outer plate; 2) making a fixing device; 3) making a pre-sprayed outer plate; 4) pouring on site ; 5) Seam sealing. The present invention uses the hook connecting rod to fix the outer plate on the wall without damaging the wall. Polyurethane is poured into the cavity formed by the outer panel and the wall, and the compressive force brought by the deformation of polyurethane foam is borne by the pre-sprayed soft foam polyurethane buffer on the outer panel. The outer panel of the invention is light and thin, has abundant optional materials, does not damage the wall during construction, and is simple in construction, and is especially suitable for high-rise operations.

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...
