Problems solved by technology

In the above two technical solutions, the thermal insulation anchors are embedded in the wall during the component manufacturing process, but usually, after the prefabricated thermal insulation wall is installed on the project site, it is necessary to add crack resistance to the outside of the thermal insulation board. The protective layer, the alkali-resistant glass fiber mesh cloth in the anti-crack protective layer is also fixed with thermal insulation nails in the traditional external wall insulation process. Although the thermal insulation anchors in the prefabricated thermal insulation wall play the role of anchoring the thermal insulation board, they have It cannot be used for post-anchoring alkali-resistant glass fiber mesh cloth
In order to anchor the alkali-resistant fiberglass mesh reliably, it is necessary to re-drill the anchor nails in the wall, but too many insulation nails will bring the risk of water seepage and leakage to the wall

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0035] refer to Figure 1 to Figure 5 As shown, an embodiment of the construction method of the insulation structure integrated prefabricated exterior wall panel of the present invention for the thermal insulation and anti-crack protection layer, the prefabricated exterior wall panel 3 is constructed by using the externally attached steel sheet 1 and the plastic anchor plate 2, and the prefabricated exterior wall panel The wall panels have been installed. The prefabricated exterior wall panels include metal anchors 4, a precast concrete structure layer 5 and an insulation layer 6. The metal anchors fix the insulation layer on the surface of the precast concrete structure layer. The...

Abstract

The invention discloses a construction method of a heat-insulation anti-crack protective layer of a heat-insulation structure integrated prefabricated external wall panel, which is characterized in that the heat-insulation anti-crack protective layer of the prefabricated external wall panel is constructed by adopting an externally bonded steel sheet and a plastic anchoring disc, and the prefabricated external wall panel comprises a metal anchoring part, a prefabricated concrete structure layer and a heat-insulation layer, the metal anchoring part is provided with a bottom plate on the surface of the heat preservation layer, at least two metal wires are fixed to the surface of the externally-attached steel sheet, and a plurality of observation holes are further formed in the surface of the externally-attached steel sheet. During construction, the bottom plate of the corresponding metal anchoring part is cleaned firstly, and the externally-pasted steel sheet is fixed to the corresponding bottom plate through glue; then, anti-crack mortar is brushed on the outer side of the heat preservation layer, and alkali-resistant glass fiber gridding cloth is hung on the outer side; the plastic anchoring disc abuts against the anti-crack mortar surface corresponding to the externally-attached steel sheet, the metal wires are bent, pressed and fixed to the plastic anchoring disc, and the alkali-resistant fiberglass gridding cloth is fixed; and water-resistant putty is brushed, and construction is finished. The construction efficiency is improved, the wall does not need to be drilled for fixation, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a construction method for a thermal insulation and anti-crack protection layer of an integrated prefabricated exterior wall panel with thermal insulation structure. Background technique [0002] The construction process of non-prefabricated building thermal insulation external wall panels is usually carried out after the construction of the structural wall is completed. The on-site construction period is long and the production cost is high. If it happens to be winter, the construction quality is difficult to guarantee. The integrated prefabricated exterior wall panel with thermal insulation function is mass-produced in the factory, and the thermal insulation and concrete structure are integrated, which greatly simplifies the later on-site thermal insulation construction process, shortens the construction period, and reduces the cost. [0003] In the traditional c...
