Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable building template supporting device. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric size, maintain its correct position, and bear the self-weight of the building formwork and the external load acting on it. Building formwork is the formwork and support for concrete pouring. According to the nature of the material, it can be divided into building formwork, building wood glue board, film-faced board, multi-layer board, double-sided glue, double-sided film-faced building formwork, etc. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork, etc. according to the construction process conditions.

[0003] After searching, it was found that the announcement number is CN220815075U, and the name is an adjustable building formwork support structure. The application proposes that in the prior art, the announcement number is CN218715149U, which discloses a building formwork support device that is easy to adjust. The problem is that it is inconvenient to use a wrench with one hand, which reduces the convenience of operating the device and increases the labor cost. The height adjustment is completed through a complex mechanical connection form. However, the application adopts a non-standard building formwork support structure, which is different from the traditional scaffolding steel pipe support system. The overall structure is complex and the overall mass is heavy. Because it is installed with a complex drive connection form inside, its outer diameter is significantly larger than the traditional scaffolding steel pipe, resulting in the inability to use traditional fasteners and unable to complete the connection with the existing scaffolding system. The interconnection components and matching cross frames are produced separately, which not only seriously increases the cost of use, but also makes it difficult to meet the construction specifications, affecting the convenience of use. The later maintenance and overhaul costs are high, which increases the burden on construction companies, and further improvements can be made. At the same time, the application is difficult to quickly center and align. When supporting under the beam, it is easy to have eccentric support problems, affecting the stability of the structure, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
