[0002] With the intensification of the global energy crisis and the improvement of environmental awareness, building energy conservation has become an important development direction of the construction industry. As one of the key links in building energy conservation, the importance of exterior wall insulation is becoming increasingly prominent. As a high-quality insulation material, homogeneous board has been widely used in the field of building exterior wall insulation due to its good insulation performance, light weight, high strength, and convenient construction. In the construction process of the homogeneous board exterior wall insulation system, it usually includes multiple links such as base treatment, bonding layer construction, insulation layer construction, plastering layer construction, and finishing layer construction. Each link requires delicate operation and strict quality control.

[0003] At present, in the prior art, the homogeneous board insulation layer is fixed by gluing during construction. After being glued over a large area, there is a lack of long-term effective fixation, which makes it more likely to cause the risk of falling off or shifting. Summary of the invention

[0006] The metal support bracket is pre-treated for corrosion resistance.

[0007] The specifications and dimensions of the metal support brackets must meet the insulation layer thickness requirements, and the installation quantity must be determined based on the floor height.

[0008] The homogeneous board insulation layer is fixed to the outer side of the outer wall by means of a strip bonding method.

[0009] The adhesive is applied to the bonding surface of the homogeneous board insulation layer, and the thickness of the adhesive applied is such that the thickness of the adhesive after bonding and extrusion is 3-5mm.

[0010] The effective bonding area of ​​the homogeneous board insulation layer is not less than 60%.

[0011] The homogeneous board exterior wall insulation construction method comprises the following steps: Step 1: Install anti-corrosion treated metal support brackets at the reinforced concrete frame beam position of the floor, and fix them on the base with expansion bolts; Step 2: Apply adhesive to the bonding surface of the insulation board, and use the strip bonding method to stick the first homogeneous board insulation layer to the initial position on the outside of the building exterior wall; Step 3, laying the homogeneous board insulation layer horizontally from bottom to top in sections, until the laying is completed; Step 4: After the adhesive has finally set, install about 50% of the expansion anchors first, and then install the remaining 50% of the expansion anchors after laying the alkali-resistant glass fiber mesh cloth.

[0012] When pasting the homogeneous board insulation layer, gently knead and squeeze it evenly to make it dense, and adjust the board with a 2m ruler and rubber hammer.

[0013] The thickness of the adhesive applied is 3-5mm after pasting and extrusion, and the effective bonding area of ​​the homogeneous board insulation layer is not less than 60% of the entire board area.

[0014] The vertical staggered joints of the upper and lower rows of homogeneous board insulation layers are 1 / 2 of the board length, and the local minimum staggered joint shall not be less than 200mm.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The exterior wall insulation homogeneous board is affixed to the building wall as a whole, reducing the hollow part of the wall. It is installed by a combination of gluing and nailing, which improves the bonding strength between the insulation board and the wall and ensures the stability and safety of the insulation system.

[0016] 2. Use anchor bolts to fix the base layer to enhance the connection between the insulation board and the base layer, and prevent the insulation board from falling off and shifting.

[0017] 3. This method is easy to operate and does not require the addition of too much additional hardware. It can be promoted and applied in corresponding fields and has good market application value. BRIEF DESCRIPTION OF THE DRAWINGS
