Manufacturing method for small concrete prefabricated blocks on construction site

Abstract

The invention discloses a manufacturing method for small concrete prefabricated blocks on a construction site. The manufacturing method comprises the following steps: manufacturing a steel mould, selecting a site with a flat surface on the construction site as a bottom plate of the steel mould, clearing the mould and coasting a mould release agent on the side walls of the mould, pouring concrete in twice and compacting through a reamer, scraping off and trowelling concrete on the upper surface of the steel mould with a trowelling tool; and lifting the mould after set time according to conditions such as a temperature, and maintaining the concrete prefabricated blocks according to an air temperature and a site condition. The manufacturing method has the advantages of being low in requirements on an operation site, high in construction efficiency, low in cost, capable of being recycled, simple and convenient in operation, and high in finished product surface quality.

Description

technical field [0001] The invention relates to a method for making a small concrete prefabricated block at a construction site. Background technique [0002] In the construction of construction projects, some small prefabricated concrete blocks are often needed. Since the amount is not large, if they are customized in a factory and then transported to the construction site, the construction cost will increase. At this time, prefabrication is often carried out at the construction site. When carrying out prefabrication processing on the construction site, the traditional method is to use wooden formwork to make molds, and the molds are composed of baffles, partitions, clamps and tension bolts. Make slots on the baffle according to the size of the prefabricated block. When installing, clamp the partition in the groove of the baffle. After the assembly is completed, use the pull bolts to reinforce it. After a group of prefabricated concrete blocks are processed, the mold is r...
