Pre-fixed plate system wall insulation system construction technology

Abstract

The invention relates to the building wall insulation system construction technology, and specifically refers to a pre-fixed plate system wall insulation system construction technology; the core of the technology is to use a drilling, pre-buried or bonding mode to lead out vertical outward thread rod from a base wall; the thread rods are bonded or hung with one or more layers of insulation plates; an outer side of the insulation plate is provided with thread caps in a screwing or knocking mode, thus firmly fixing the insulation plates on the base wall; then later polishing-plastering netting steps are followed. The pre-fixed plate system wall insulation system construction technology solves seepage and virtual fixation disadvantages of the conventional technology, optimizes a construction flow, ensures engineering quality, reduces construction cost, and has wide application in civil building and cold storage engineering.

Description

technical field [0001] The invention relates to a construction process of a building wall thermal insulation system, in particular to a construction process of a pre-fixed plate system wall thermal insulation system Background technique [0002] Energy conservation and emission reduction is a common problem faced by the whole world, and building energy conservation is an important part of it. The external thermal insulation system of building exterior wall is an important means to realize building energy saving. At present, the thin-plaster external wall external thermal insulation system based on various thermal insulation boards is usually used as the basic form of external wall thermal insulation. [0003] At present, the construction process of plastered exterior wall external insulation system based on thermal insulation board is basically the same. In summary, after the base wall is treated, the thermal insulation board is pasted first, and then the fixing parts are d...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the insulation board is installed first, and then the fixing parts are drilled, the quality of the hole cannot be observed

In actual engineering, it is also impossible to clean the dust in the hole

[0006] 2. The drilling depth must be greater than the thickness of the insulation board plus the depth into the base wall, and a longer drill bit is required

If it is in severe cold areas such as Northeast China or when the energy saving requirements are further improved, a drill bit with a length of 20-30 cm is required, which is not easy to construct, easy to break the drill, easy to cause reaming, and affect the installation quality of the fixing parts.

[0007] 3. For the rainy areas in the south, when it is required to plug the hole, due to the existence of the insulation board, it cannot be effectively plugged and waterproof

[0008] 4. For projects such as cold storage, when it is necessary to install multi-layer insulation boards (sometimes up to 4-6 layers), it is impossible to use one fixing piece to fix multi-layer insulation boards at the same time, and it is necessary to adopt various temporary fixing measures or transitional measures, which will affect the progress. also increase the cost

[0009] 5. In the short term after the insulation board is pasted, when installing the fixing parts, it is easy to disturb the bonding mortar, which will affect the bonding strength and cause virtual sticking
