Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a post-casting formwork device for column foot splitting in floor construction. Background Art

[0002] Flooring refers to the floor that is constructed using specific materials and processes to present a certain decorative and functional floor, such as epoxy self-leveling floor, corundum wear-resistant floor, epoxy terrazzo floor, cement-based terrazzo, epoxy colored sand floor, epoxy anti-static floor, epoxy anti-slip floor, polyurea anti-corrosion floor, polyurethane floor, silicon PU floor, concrete sealing and curing agent floor, etc.

[0003] After searching, a Chinese patent discloses a post-casting formwork device for column bases during floor construction (authorization announcement number CN220487108U), "including a first template and a second template, a connecting end is provided between the first template and the second template, the connecting end includes a hexagonal connecting device and a conversion cylinder, the conversion cylinder is located inside the hexagonal connecting device, a bearing base is provided at the bottom of the conversion cylinder, and the conversion cylinder and the bearing base are connected, the surface of the hexagonal connecting device is provided with a first through hole, and the first through hole array is distributed on the surface of the hexagonal connecting device. It solves the problem that the floor column base is prone to cracking after the cutting. When cutting the seam at the edge of the floor column, the cutting is generally carried out along the column base after the floor construction is completed, which can easily cause cracks in the ground. This finished formwork tool is used to support the formwork first and then cast, which avoids the damage of the floor surface layer by cutting the seam after casting. The use of this post-casting formwork device for column bases during floor construction can effectively solve the problem that the cutting of the floor column base is prone to cracks."

[0004] Although the above-mentioned formwork device can effectively solve the problem that cracks are easily generated in the cutting seams of the floor column bases, the formwork and the hexagonal connecting device are assembled and disassembled using bolts. Due to the small space in the conversion cylinder, it is not easy to pass the bolts through the through holes on the conversion cylinder and the hexagonal connecting device and then into the formwork. Two wrenches are needed to tighten the bolts, and the disassembly efficiency is low. In addition, once the staff tightens the bolts with too much force, the thread may slip, making the subsequent disassembly very troublesome. Utility Model Content
