Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a template structure for casting the outer columns at the corners of a flat warehouse. Background Technology

[0002] Flat warehouses are core facilities in the grain storage sector. To maximize their grain storage space, structural columns are typically designed as external columns, meaning that one corner of a rectangular column is flush with two perpendicular walls of the building, while the other three corners do not occupy interior space.

[0003] Considering the functionality, structural safety, and cost of flat warehouses, their structural design typically consists of a "structural frame + masonry load-bearing walls + horizontal connecting beams." To ensure the structural safety of the masonry load-bearing walls under grain storage conditions, the height of a single load-bearing masonry wall cannot be too high at one time. The entire structural surface of the warehouse wall is formed by repeated alternations of masonry load-bearing walls and horizontal connecting beams. During construction, in addition to ensuring the structural safety of the warehouse wall, the airtightness requirement of the warehouse wall must also be strictly guaranteed. Therefore, the traditional construction method of pouring concrete for the main structure first and then constructing the masonry cannot be used. When constructing flat warehouses, the masonry walls are first built to the level of the horizontal connecting beams, and then the connecting beam reinforcement is tied, the formwork is erected, and the concrete is poured. This maximizes the airtightness requirement of the flat warehouse. However, the prior construction of the masonry walls restricts the reinforcement space for the corner column formwork, resulting in construction difficulties and making it difficult to guarantee the construction quality.
