Exterior wall cladding system integrating insulating layer, decorative layer and formwork and construction method thereof

Abstract

The invention discloses an exterior wall cladding system integrating an insulating layer, a decorative layer and a formwork and a construction method thereof. The system comprises multiple cold-bending profiles, multiple pre-punched holes are formed in the side face of each cold-bending profile, and the cold-bending profiles are connected in pairs through multiple tie bars and are placed in a reinforcement cage; the system further comprises multiple external hanging formworks, each external hanging formwork integrates the insulating layer, the decorative layer and the formwork, multiple hanging parts are arranged on each external hanging formwork, and the external hanging formworks are hung on the pre-punched holes through the hanging parts and can be connected again through the tie bars; multiple internal formworks are arranged at the relative positions parallel to the external hanging formworks, and opposite pull is formed between the external hanging formworks and the internal formworks to offset mold expanding force. The cold-bending profiles serve as a part of rebars of a shear wall system, the tie bars are additionally arranged in the reinforcement cage to ensure the accurate size of the reinforcement cage, and the hanging parts can be arranged to be of a clamping groove suspension structure. By means of the specially-made reinforcement cage and the prefabricated external hanging formworks, the system is assembled into a container shape high in integral rigidity, a great number of original scaffold projects for ensuring stability of the system are omitted, manpower and material resources are saved greatly, and the economic effect is remarkable.

Description

technical field [0001] The invention relates to the field of industrial and civil buildings, more precisely, it relates to an exterior wall hanging board system and a construction method thereof integrating an insulation layer, a decoration layer and a formwork. Background technique [0002] There are roughly three types of wall insulation today: ① external thermal insulation; ② internal thermal insulation; ③ single material thermal insulation. Due to the various disadvantages of internal heat preservation, such as taking up more indoor space; the problem of "thermal bridge" is not easy to solve; it is difficult to fix objects on the wall, especially when residents undergo secondary decoration, there will be more damage, which will affect the heat preservation effect; due to the building structure External wall exposure, internal insulation cracking caused by temperature difference changes, etc. Internal thermal insulation will be gradually replaced by reasonable external t...

AI Technical Summary

Problems solved by technology

[0006] The core of the present invention is to unify the functions of the original thermal insulation layer, exterior wall decorative surface layer, and formwork support system to form a whole, and through the connecting piece or connecting bolt and the holed profile in the reinforcement cage to replace the longitudinal main reinforcement. Hole connection, the modulus of the connecting parts of the two is uniform; since the formwork tension is very large during construction, a certain number of tie bars are set between the cold-formed profiles from a mechanical point of view; Using high and low grooves (if necessary, add foam or rubber strips), the upper and lower wall panels are connected to each other as a whole to avoid grout leakage; from an economic point of view, the external wall insulation and external hanging panel system fundamentally solves the problem of traditional concrete walls There are many problems such as long construction period of multi-process and low safety
