Description

Technical Field

[0001] The utility model relates to the technical field of precast slab processing, and specifically relates to a precast slab mold. Background Technique

[0002] Precast slabs are the floor slabs used in early 20th-century buildings. They are the modules or plates used in engineering. Because they are concrete precast components produced and processed in a precast yard and directly transported to the construction site for installation, they are called precast slabs. When making precast slabs, first nail a hollow model with wooden boards, lay steel bars in the hollow part of the model, then fill the hollow part with cement, and after drying, knock off the wooden boards, and what remains is the precast slab. Precast slabs have many uses in construction, such as the cement slabs covering the ditches beside the road; the cement slabs used as heat insulation layers on the roof are all precast slabs.

[0003] Among them, corresponding molds are used in the processing of precast slabs. There is a cement precast slab mold with the Chinese patent publication number CN214187673U. Through its pressing mechanism, the front template, rear template, left template, and right template can be tightly pressed inward, making the mold more stable, thereby ensuring that the cement precast slab will not deform or crack, and improving the strength and service life of the cement precast slab.

[0004] However, since the device makes and holds the precast slab through the substrate, it is difficult to take out and has insufficient practicality. Content of the Utility Model
