Abstract

The invention relates to a pouring mold and pouring process for a light-weight aggregate concrete PC component, and belongs to the field of concrete prefabricated part pouring. The pouring mold comprises a bottom mold, a plurality of vertically-connected vertical molds and a mold sealing plate, wherein one or more grouting connectors are arranged on the bottom mold; the vertical molds are arrangedto be annular frames with upper openings and lower openings, vertical mold flanges are arranged at the upper openings and the lower openings, the adjacent vertical molds are connected through the vertical mold flanges, and the vertical mold on the lowermost layer is connected with the bottom mold through the vertical mold flanges; and exhaust holes are formed in the mold sealing plate, and the mold sealing plate is connected to the vertical mold flanges. According to the pouring mold, the grouting connectors are formed in the bottom mold, light-weight aggregate concrete is injected into the pouring mold from the lower part through the grouting connectors, air in the pouring mold is exhausted upwards, the light-weight aggregate concrete does not need to be vibrated, the light-weight aggregate is evenly distributed in the pouring mold, and the pouring quality of a light-weight aggregate concrete prefabricated component is improved.

Description

technical field [0001] The present application relates to the field of pouring concrete prefabricated parts, in particular to a pouring mold and pouring process for lightweight aggregate concrete PC components. Background technique [0002] Lightweight aggregate concrete refers to concrete using lightweight aggregate, and its apparent density is not more than 1900kg / m3. The so-called lightweight aggregate is an aggregate used for the purpose of reducing the quality of concrete and improving the thermal effect, and its apparent density is lower than that of ordinary aggregate. Lightweight aggregate concrete has the characteristics of light weight, high strength, heat preservation and fire resistance, and has good deformation performance and low elastic modulus. Lightweight aggregate concrete is used in industrial and civil buildings and other projects. It can reduce the structural weight, save material consumption, improve component transportation and hoisting efficiency, re...
