AI Technical Summary
The existing formwork-free molds for casting structural columns lack stability between the U-shaped hollow blocks and the reinforcing steel bars of the structural columns, which makes the U-shaped hollow blocks easy to separate during casting, affecting the construction effect.
The system employs a combination structure of steel trusses and mounting blocks, which are connected by fastening bolts and nuts to increase the stability between the U-shaped hollow blocks and the steel trusses. The use of sliders and grooves ensures the stable installation of the U-shaped hollow blocks.
This improved the stability between the U-shaped hollow blocks and the steel truss, prevented the blocks from separating during the pouring process, and ensured the forming quality and construction progress of the structural columns.
