Method for manufacturing precast concrete member and used molding equipment thereof

Abstract

The invention relates to a method for manufacturing a precast concrete member and used molding equipment for implementing the method. The method for manufacturing the precast concrete member enables concrete to be filled in completely, enables dense exhausting to be fully carried out and improves quality and intensity of concrete component products. The method for manufacturing the precast concrete member comprises the following steps that (a) a plurality of core tubes having identical external dimensions with component through holes and identical overall dimensions with grooves are inserted into a molding cavity of the molding equipment and are supported; (b) concrete is poured into the molding cavity until the molding cavity is filled; (c) a plurality of vibrating tubes are made to penetrate through the molding equipment to be inserted into the molding cavity, a vibrating motor is started simultaneously with the inserting of the vibrating tubes, inserting of the vibrating tubes into the molding cavity and vibrating are carried out at the same time, the vibrating tubes are pulled back after being inserted into the molding cavity completely, and the vibrating motor is switched off after the vibrating tubes are pulled out completely; (d) concrete is poured into the molding cavity with concaves emerged until the molding cavity is filled again; (e) after initial set occurs to the concrete, the core tubes are pulled out from the molding cavity; (f) the concrete members are taken out after the concrete is condensed completely.

Description

technical field [0001] The invention relates to a manufacturing method of prefabricated concrete components in the construction field and supporting equipment for implementing the method. Background technique [0002] With the transformation and upgrading of the traditional construction industry to the modern construction industry, the development of housing industrialization has become inevitable. Housing industrialization is to realize the factory production of housing components. First of all, it requires the factory production of building components. Building components mainly include prefabricated building walls. Concrete components, prefabricated concrete components for building slabs and other supporting building parts materials. [0003] In the prior art, there are many kinds of prefabricated concrete member structures, all of which are formed by injecting concrete into the mould.

[0003] In the prior art, there are many kinds of prefabricated concrete member structures, all of which are formed by injecting concrete into the mould. The Chinese patent application with the publication number 103074955A filed by the applicant records that a plate body has multiple through holes and recesses. The structure of the groove, when producing components with such a structure, due to the need to arrange a number of core tubes in the cavity to form through holes and grooves at intervals, the space in the cavity is narrow and complicated, so that the concrete can be completely injected into the prefabricated component. All parts are very difficult, let alone fully compacted and vented concrete, which affects the quality and strength of components
