Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated column moulds, in particular to a prefabricated column mould which is convenient for demoulding. Background Art

[0002] Precast columns are columns made of reinforced concrete. They are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic structures. They are often used as floor supports, bridge piers, foundation columns, towers, and compression rods for trusses.

[0003] Prefabricated columns often require related molds to plasticize them during production. However, the mold needs to be disassembled after pouring. A Chinese patent discloses a prefabricated column mold that is easy to demold (authorization announcement number CN214353160U). This patented technology can achieve the airtightness of the mold joint by splicing the structure. The top mold is inverted on the top of the bottom mold, and the slot and the block are tightly engaged. Then, the fixing bolts set inside the splicing plates at both ends of the bottom mold and the top mold are fixed with bolts. When pouring concrete into the assembled mold, the concrete will flow into the gap between the slot and the block. Since a layer of sealing gasket is fixed inside the slot, the gap at the connection between the slot and the block is blocked, thereby preventing the concrete inside the mold from leaking.

[0004] However, although the problem of concrete leakage can be avoided in actual use, rectangular prefabricated columns cannot be produced in actual use, and it is not convenient to disassemble them. In order to solve the above problems, we have made improvements and proposed a prefabricated column mold that is easy to demold. Utility Model Content
