AI Technical Summary

Technical Problem

The construction of building exterior walls presents challenges such as difficulty in reinforcing the formwork on the exposed surfaces, inadequate reinforcement leading to bulging, misalignment at the junction of upper and lower floors, exposed rebar, and voids. The construction period is also long and highly susceptible to weather conditions, especially the high risk factor associated with suspended platform construction.

Method used

The prefabricated insulated exterior wall construction structure includes a standard insulated wall and a diagonal bracing structure. Through the combination of anchor holes, anchor bars, horizontal anchor bars and diagonal bracing structure, a reliable connection between the standard insulated wall and the existing wall and interlayer slab is achieved. Waterproofing is carried out, and grouting material is used for tight anchoring. Combined with temporary fixing and position adjustment of the diagonal bracing structure, the construction accuracy is ensured.

Benefits of technology

It improves the integrity and stability of the exterior walls and interlayer slabs, avoids misalignment and water leakage, shortens the construction period, improves construction quality and safety, and reduces environmental dependence.

Abstract

The invention discloses a construction structure and method of an assembly type heat preservation outer wall, anchoring holes are formed in the top of a standard heat preservation wall body and the top of an external existing wall body, and anchoring steel bars are fixedly arranged at the bottom of the standard heat preservation wall body; horizontal anchoring ribs and grouting holes are arranged on the side face of the standard thermal insulation wall body, and the grouting holes are communicated with all the anchoring holes; the bottom of the standard thermal insulation wall body is fixedly connected with a lower standard thermal insulation wall body or an external existing wall body; one end of each horizontal anchoring rib is fixed on the inner side surface of the standard thermal insulation wall body, and the other end of each horizontal anchoring rib is fixed on to-be-poured interlayer plate reinforcing steel bars with the same elevation; one end of the cable-stayed bracing structure is fixed to the lower poured interlayer plate, and the other side of the cable-stayed bracing structure is fixed to the standard heat preservation wall. Based on the measures, the problems that an outer wall formwork is difficult to reinforce, the construction period of an outer wall heat preservation hanging basket is long, the environment influence is large, and the danger coefficient is large are solved; and the construction procedures of outer wall reinforcement and outer wall heat preservation are reduced, the construction progress is accelerated, and the construction quality is improved.
