Component prefabricated mold

Abstract

The invention provides a component prefabricated mold used for prefabricating a concrete component. The component prefabricated mold comprises a mold body and a semi-closed hanging formwork, the semi-closed hanging formwork comprises a flat portion, the flat portion is horizontally disposed, and the flat portion is provided with at least one shear key mold; the semi-closed hanging formwork is provided with a positioning portion which is fixedly connected to the mold body and the flat portion, and the positioning portion makes the flat portion locate above the mold body. According to the component prefabricated mold, the semi-closed hanging formwork which can achieve the forming of a shearing key of the top surface of the component and achieve water collecting and leveling operation of concretes on the top surface of the component is fixedly arranged on the top of the mold body, so that the component prefabricated mold ensures that pouring of the concretes is dense and the surfaces of the concretes are flat while the shearing key is formed in the top of the component, and the dimensional accuracy of the component is effectively improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a component prefabricated mold. Background technique [0002] In the existing construction engineering field, prefabricated concrete components and installation on the construction site are the future development trends. Common concrete components include columns and cover beams. Compared with building component molds on the construction site and pouring them directly, these precast concrete components have the advantages of easy on-site management and high construction accuracy. However, compared with cast-in-place, due to the size limitation of precast concrete members, a complete member needs to be spliced ​​by multiple precast member nodes, and multiple pairs of shear keys need to be set on the joint surface of two adjacent precast member nodes. to connect with each other. [0003] In the prior art, the mold for manufacturing the precast concrete component is complet...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the fact that the molds for manufacturing precast concrete components in the prior art are completely closed. During the pouring and tamping process, air bubbles are often precipitated inside the concrete, and they will shrink and form water when the concrete is solidified. , so this kind of completely closed mold will not be able to collect water and level the concrete when it is solidified, which will cause the top surface of the finished component to be uneven, and there will be quality defects such as air bubbles and voids, which cannot meet the requirements of bridge construction. Defects in precision requirements, providing a prefabricated mold for components
