Description

Technical Field

[0001] The utility model relates to the technical field of shear wall formworks, in particular to a special aluminum alloy formwork for an assembled concrete shear wall structure. Background Art

[0002] At present, in the construction of cast-in-place concrete structures, formwork is needed as a mold for forming concrete structures or reinforced concrete structures. The formwork is generally composed of a panel and a support system (including keels, trusses, beams, etc., as well as vertical support structures), and connecting accessories (including bolts, connecting buckles, and connecting parts and accessories between the formwork surface and the supporting components and between the supporting components). The formwork is divided into steel formwork, aluminum alloy formwork, bamboo plywood, wooden formwork, and plastic board according to the material.

[0003] Traditional aluminum alloy formwork is often used in large-scale cast-in-place concrete structure construction. However, aluminum alloy formwork is rarely used in the formwork construction of local cast-in-place structures in prefabricated concrete buildings. The local cast-in-place structures in prefabricated concrete buildings mainly refer to the post-cast concrete structure used in the handover area when it is connected with other prefabricated components connected to prefabricated shear walls and prefabricated shear walls. Since most prefabricated concrete shear wall buildings only have the node areas cast in place, and the cast-in-place area is relatively small, wooden formwork is now mostly used for on-site assembly. The disassembly and assembly of the formwork is time-consuming and labor-intensive, and the work efficiency is low.

[0004] For example, Chinese patent CN214834717U discloses a special aluminum alloy formwork for a prefabricated concrete shear wall structure. Through the cooperation of an inner angle formwork, an inner straight formwork, an outer angle formwork and an outer straight formwork, the aluminum alloy formwork can be enclosed on-site at the junction area of ​​the prefabricated concrete shear wall, thereby solving the problem of time-consuming and labor-intensive on-site binding of wooden formworks, and facilitating the pouring of the junction area. Through the mutual cooperation of a first connecting groove, a first connecting plate, a first fastening screw and a first screw hole, the inner angle formwork and the inner straight formwork can be quickly assembled. Through the mutual cooperation of a second connecting groove, a second connecting plate, a second fastening screw and a second screw hole, the outer angle formwork and the outer straight formwork can be quickly assembled, thereby improving work efficiency.

[0005] However, the device cannot adjust the distance between the inner angle template and the inner straight template during use, thereby reducing the practicality of the device.

[0006] For this reason, we urgently need to provide a special aluminum alloy formwork for assembled concrete shear wall structure. Utility Model Content
