The invention aims to solve the system quality problems of cracking, water seepage and the like caused by local cold and hot bridges generated by penetrating type connecting pieces adopted by the traditional composite heat-insulation template, and simultaneously solve the system safety and practicability problems caused by heavy weight and thick plastering of the traditional composite heat-insulation template.
Description
Technical Field
The invention relates to the technical field of wall heat preservation, in particular to a cast-in-place concrete heat preservation integrated wall structure fixed by adopting a non-penetrating connecting piece and a construction method thereof.
Background
At present, the construction method mainly adopted in the construction of the integrated technology of the external thermal insulation engineering thermal insulation structure of the building external wall is as follows: the heat-insulation board is reinforced and compounded through mortar to achieve certain anti-bending load capacity, the heat-insulation board can be directly used as a non-dismantling heat-insulation template, the connecting piece is fixed with the compound heat-insulation template through penetrating through the compound heat-insulation template, the connecting piece bolt is bound and fixed with the reinforcing steel bar, and the connecting piece is cast with the concrete wall body into a whole during cast-in-place, so that the connecting piece is connected and fixed with the wall body, and the system is called as a non-dismantling external heat-insulation template cast-in-place concrete system.
The adopted composite heat-insulation template as the disassembly-free external template needs to be capable of bearing the impact of concrete on the composite heat-insulation template during cast-in-place concrete, so that the thickness of a mortar composite layer is thicker and at least needs to reach more than 12mm so as to reach certain strength and bending load resistance, and the surface density generally reaches more than 35 kg/square meter. The composite heat-insulating template has larger weight, the composite flatness is difficult to control, and the construction difficulty is large. Meanwhile, when the penetrating type connecting piece is adopted, on one hand, the penetrating hole of the connecting piece destroys the integrity of the inner surface and the outer surface of the composite heat-insulation template, obvious cold and hot bridge concentration points can appear at the mounting position of the connecting piece in a heat-insulation system, and the risk of surface layer cracking and water seepage is very easy to appear at the position; on the other hand, the disc at the tail end is positioned on the outer surface of the composite heat-insulation template and shows a convex trend, the plastering on the next step of the composite heat-insulation template needs a larger plastering thickness during leveling treatment, the self weight of the heat-insulation outer side wall body is larger, larger shearing force is generated on the heat-insulation layer in the system, the heat-insulation layer is extremely easy to crack, and the safety and the practicability of the outer wall heat-insulation system are influenced.
