Outside thermal insulation construction method for anchoring and sticking composite thermal insulation plate outside wall

Abstract

The invention relates to walls (roof coverings) of industrial and civil buildings, in particular to a heat conservation construction method for bonding cement based environmental protection thistle boards and insulation plates into composite insulation plates to anchor and adhere outside the outer walls of the composite insulation plates. The invention is characterized in that firstly adhesion agent 6 is used for adhering the insulation plates 3 and the cement based environmental protection thistle boards 5 into the composite insulation plates for standby application; secondly, microfoam gum 2 is used for adhering the composite insulation plates with base courses 1, and nylon sleeve steel nails 4 are used for anchoring in a construction site; thirdly, location references are formed by the mortise-and-tenon joint structure of each L-shaped groove and tongue 10 of two adjacent composite insulation plates, the flatness of the outer surface is also ensured, abutment joint positions are coated with foam rubber 11 to be sealed, flexible anti-cracking putty 7 is applied to the outer surfaces of preprocessed grooves with 1.5 to 2.0 mm depth and 50 to 80 mm width, alkali proof mesh cloth 8 is pressed in the grooves, then the flexible anti-cracking putty 7 is applied, the grooves are leveled up by using the method of pressing the cloth once and applying the putty twice; fourthly, the depressions of the holes of the TOX nylon sleeve steel nails 4 are leveled up by flexible anti-cracking putty 12 made of the same material. When facings 14 are the styles of imitation aluminum-plastic curtain wall facings or imitation facing brick facings, weatherproof silicone seal gum 13 is applied for sealing ornamental joints.

Description

1. Technical field [0001] The invention relates to walls (roofs) of industrial and civil buildings, in particular to a construction method for applying cement-based environmentally friendly lightweight boards and insulation boards to form composite insulation boards, anchoring and bonding composite insulation boards for external wall insulation. 2. Background technology [0002] my country's building energy-saving standards are advancing to 65%, and will continue to increase. However, the style of external thermal insulation engineering decoration is increasingly rich and multi-grade. So far, most of the external thermal insulation technologies for external walls are constructed on site and pollute the environment; moreover, thermal insulation, waterproofing, and decoration must be constructed independently, so it is impossible to achieve the multifunctional requirements of thermal insulation, waterproofing, and decoration in one construction; the non-polyurethane rigid foam...

AI Technical Summary

Problems solved by technology

So far, most of the external thermal insulation technologies for external walls are constructed on site and pollute the environment; moreover, thermal insulation, waterproofing, and decoration must be constructed independently, so it is impossible to achieve the multifunctional requirements of thermal insulation, waterproofing, and decoration in one construction; the non-polyurethane rigid foam currently used The external insulation structure of the insulation layer generally has defects such as high thermal conductivity of the insulation layer, easy cracking, and water seepage; and the construction method of spraying polyurethane insulation layer also has certain defects: 1. Spraying construction causes polyurethane microfoam to float, which seriously pollutes the environment

2. The floating loss of polyurethane microfoam and the smoothness of polyurethane surface repair cause excessive waste of raw materials

3. It takes a lot of man-hours to repair the polyurethane surface

4. The cross-sectional density of the sprayed polyurethane insulation layer is not uniform, and the quality accidents of the external insulation project due to the volume shrinkage of the insulation layer occur from time to time
