Description
Technical Field
The invention relates to the technical field of fabricated buildings, in particular to a construction method of a heat-insulating anti-cracking protective layer of a prefabricated external wall panel with an integrated heat-insulating structure.
Background
The construction process of the non-prefabricated assembled building heat-insulating external wall panel usually can carry out external heat-insulating construction after the construction of a structural wall is finished, the field construction period is long, the production cost is high, and the construction quality is difficult to ensure even in winter. The integrated prefabricated external wall panel with the heat insulation function is produced in batches in a factory, and the heat insulation and concrete structure are integrally manufactured, so that the later-stage on-site heat insulation construction process is greatly simplified, the construction period is shortened, and the cost is reduced.
The traditional construction method of the heat-insulating anti-cracking layer comprises the steps of firstly leveling mortar for a wall surface, then coating an interface agent to adhere to a heat-insulating plate, coating anti-cracking mortar on the surface of the heat-insulating layer, then paving alkali-resistant glass fiber net grid cloth, separating seams, pressing the alkali-resistant glass fiber net grid cloth into the grooves by using a trowel to form grooves, pressing and coating by using force, and then pressing the grid cloth into the mortar. After the anti-crack mortar is solidified, the insulation board is driven with insulation nails for reinforcement, and then the anti-crack mortar or the waterproof putty is brushed. Therefore, in the traditional external wall heat insulation process, the heat insulation nails are used for fixing the heat insulation boards and fixing the alkali-resistant glass fiber gridding cloth.
The existing assembled heat-insulating external wall panel is a sandwich external wall panel consisting of a concrete outer leaf wall panel, a heat-insulating plate and a concrete inner leaf wall panel, and the concrete outer leaf wall panel and the concrete inner leaf wall panel are connected in a mode that a special connecting piece penetrates through a heat-insulating layer. The connecting piece constraint effect is stronger, and the stress that outer leaf plate temperature deformation produced is difficult to release under the cold and hot circumstances in turn, has outer leaf plate concrete fracture risk, has the risk of droing even, causes serious potential safety hazard.
Therefore, technical personnel propose an integrated prefabrication method for placing an insulation board on the outer surface of a wall body, such as a composite prefabricated external wall board with an insulation structure and a production process thereof mentioned in patent CN 110748080A, and a prefabricated external wall structure with an insulation effect and a manufacturing method thereof mentioned in patent CN 105064532 a. In the two technical schemes, the heat-insulating anchoring parts are all embedded into the wall body in the manufacturing process of the components, under the normal condition, after the prefabricated heat-insulating wall body is installed on the engineering site, an anti-cracking protective layer needs to be added on the outer side of the heat-insulating plate, the alkali-resistant glass fiber gridding cloth in the anti-cracking protective layer is fixed by the heat-insulating nails in the traditional outer wall heat-insulating process, and the heat-insulating anchoring parts in the prefabricated heat-insulating wall body play a role of anchoring the heat-insulating plate, but cannot be used for anchoring the alkali-resistant glass fiber gridding cloth in the later period. If the alkali-resistant glass fiber mesh cloth needs to be anchored reliably, the anchoring nails need to be drilled in the wall body again, but the risk of water seepage and water leakage is brought to the wall body due to the fact that the heat-insulating nails are arranged too much.
In summary, it is urgently needed to develop a construction method of a thermal insulation anti-cracking protection layer of a thermal insulation integrated prefabricated external wall panel.
