Description

Technical Field

[0001] The utility model relates to the field of core molds, in particular to a pull-out type prefabricated beam and slab built-in core mold. Background Art

[0002] When prefabricating hollow bridge slabs, a core mold must be placed in the beam body to create the hollowness. After the concrete is poured and formed, the core mold must be removed. Removing the mold is often a very troublesome task, because the concrete will stick to the core mold during the solidification process, and the concrete will also expand during the solidification process, squeezing the core mold and increasing the bonding strength of the concrete. The current practice of removing the core mold is to arrange workers to climb into the core mold, loosen the screws, disassemble the core mold, and then use a winch to pull the core mold out. Not only is the space inside the core mold small and inconvenient for operation, but the temperature is often as high as 50 degrees Celsius. The working environment is relatively harsh, and the workers need to work inside for at least 30 minutes. The difficulty can be imagined, so the work of removing the core mold will bring more costs to the product.

[0003] For example, in a patent for a pull-out prefabricated beam and slab built-in core mold (Announcement No.: CN214238735U), it includes a left core mold and a right core mold. A single core mold includes two hinged templates. The left core mold and the right core mold are spliced ​​into a built-in core mold. A core mold skeleton is provided inside the core mold. Support frames are provided on both sides of the core mold skeleton. One end of the support frame is hinged to the core mold skeleton, and the other end is hinged to the inner side of the core mold. A limit block is provided on the core mold skeleton, and the support frames on both sides of the core mold skeleton are against one side of the limit block. The limit block is used to simply limit the support frame on one side, so that the entire support frame can only rotate to one side. A hydraulic cylinder can also be used to drive the support frame to realize auxiliary demolding. The overall rigidity is large, and the installation and disassembly are convenient and quick. The template will not deform during installation and disassembly, which can improve the construction quality and construction progress.

[0004] The above patent can improve the construction quality and construction progress by built-in core mold and support frame. In daily use, the core mold will rotate through the support frame to bend the middle hinge to realize mold removal, resulting in the upper and lower ends of the core mold still needing to be separated from the prefabricated beam by the staff, thereby affecting the disassembly speed of the device and reducing the disassembly efficiency of the device. Therefore, it is necessary to invent a pull-out prefabricated beam plate with built-in core mold to solve the above problem. Utility Model Content
