Prefabricated wall formwork assembly and manufacturing and mounting method thereof

Abstract

The invention relates to the technical field of wall formworks and discloses a prefabricated wall formwork assembly. The prefabricated wall formwork assembly comprises a prefabricated outer wall layer, a prefabricated inner wall layer and a reinforcing structure, wherein the reinforcing structure is composed of a plurality of prefabricated positioning connecting fasteners; each prefabricated positioning connecting fastener comprises a connecting part, a front fastening part arranged at the front end of the connecting part and a rear fastening part arranged at the rear end of the connecting part; the prefabricated outer wall layer is formed by stacking a plurality of prefabricated outer wall formworks; front positioning connecting clamping grooves are formed in the peripheries of the prefabricated outer wall formworks; the prefabricated inner wall layer is formed by stacking a plurality of prefabricated inner wall formworks; and rear positioning connecting clamping grooves are formed inthe peripheries of the prefabricated inner wall formworks. The invention further discloses a manufacturing and mounting method of the prefabricated wall formwork assembly. The prefabricated wall formwork assembly has the advantages of high structural strength, high mounting efficiency and high reliability.

Description

technical field [0001] The invention relates to the technical field of wall formwork, in particular to a prefabricated wall formwork assembly and its manufacturing and installation methods. Background technique [0002] In the traditional exterior wall construction, after the steel bars are tied, the workers install the external and internal formwork and the support system on the scaffold platform and the floor respectively. The concrete pouring cavity is formed, and the formwork and support are removed after the concrete reaches the formwork removal strength. As we all know, the traditional construction method has defects such as low construction efficiency and high labor intensity. With the rapid development of building formwork, in recent years, non-demolition formwork has appeared. As a part of the wall; if it is used as an outer wall, the inner side is generally bonded with an insulating layer, and the outer side can also be provided with a decorative layer, so that th...

As we all know, the traditional construction method has defects such as low construction efficiency and high labor intensity. With the rapid development of building formwork, in recent years, non-demolition formwork has appeared. As a part of the wall; if it is used as an outer wall, the inner side is generally bonded with an insulating layer, and the outer side can also be provided with a decorative layer, so that the decorative layer and the insulating layer can be formed at one time, which greatly improves the construction efficiency. The insulation layer in the integrated exterior wall formwork generally adopts a plane bonded structure, but this type of formwork assembly has the following defects: ① When assembling adjacent prefabricated wall formwork, it is necessary to place expansion joints at the junction to prevent multiple prefabricated walls Deformation and cracking occur between the body formwork, but the fixing of the expansion joint strip is very unreliable, and it is easy to fall off or be squeezed out, causing the entire prefabricated wall formwork assembly to be easily loosened; ② Due to the need to form a pouring cavity, the existing external wall and The internal wall structure has low strength and poor stability, and the overall strength of the entire prefabricated wall formwork assembly finally formed is insufficient, resulting in poor pouring effect in the pouring cavity
