Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete piles, in particular to a precast concrete pile mould. Background Art

[0002] Precast reinforced concrete piles are prefabricated in a prefabricated component processing plant, and after being cured and reaching the designed strength, they are transported to the construction site, driven into the soil with a pile driver, and then the pedestal beam (slab) foundation is poured on the top of the pile. Precast reinforced concrete piles have the advantages of easy production, high strength, high rigidity and can be made into various cross-sectional shapes. They are the most widely used pile type.

[0003] At present, most of the concrete precast pile molds on the market are equipped with a device for adjusting the mold plate to adjust the size of the mold when the size of the precast pile is to be adjusted. The adjustment plate for adjusting the size of the mold must be fixedly connected before pouring concrete, but the exact amount of concrete will not be poured in. During the drying process of concrete, the concrete often squeezes the fixed adjustment plate, which will cause deformation of the adjustment plate after repeated use, which is not conducive to the accurate pouring of concrete thereafter. In addition, the existing concrete precast pile structure is single and can only complete a single pile shape. The device does not have the function of splicing and dismantling to adjust the length of the concrete precast pile during use, and it is not convenient for combined installation. For this reason, we provide a concrete precast pile mold. Summary of the invention
