Description

Technical Field

[0001] This invention relates to the field of structural column casting equipment technology, specifically a casting mold for building construction. Background Technology

[0002] Structural columns refer to reinforced concrete structural columns that should be installed in the walls of multi-story brick-concrete structures to enhance the integrity and stability of the building. These columns are connected to the ring beams of each floor to form a spatial frame that can resist bending and shearing, and are an effective measure to prevent the building from collapsing.

[0003] However, after the existing structural columns are cast using molds, the excess concrete at the flared end still needs to be removed. This removal work is not only wasteful of manpower, time, and effort, affecting subsequent procedures, but also generates construction waste that causes environmental pollution. Furthermore, most of the existing casting molds are fixed, one-piece structures that are large in size, making them inconvenient to transport, difficult to combine and adjust according to the current height requirements of the construction, and difficult to dismantle and reuse. All of these factors have a negative impact on the casting of structural columns in building construction. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a casting mold for building construction.
