Combined die plate

Abstract

The invention belongs to the technical field of building prefabricated parts, and discloses a combined die plate for molding a prefabricated part. The combined die plate at least comprises a first flange die plate body and a second flange die plate body; the first flange die plate body is located on the upper portion of the second flange die plate body, the first flange die plate body and the second flange die plate body are connected into a whole through a connecting and fixing device, and the connecting and fixing device is located on the same side of the first flange die plate body and the second flange die plate body. According to the combined die plate, a die is subjected to function or specification splitting and split into multiple die plate bodies such as the first flange die plate body and the second die plate body, the die plate bodies are combined into a combined flange die plate, and the combined die plate is fixed to a bottom die through the connecting and fixing device; accordingly, not only is the die conveniently managed, but also one die can achieve multiple purposes, the repeating utilization rate of the die is increased, and the apportioned cost of the die is reduced.

Description

technical field [0001] The invention belongs to the technical field of building prefabricated parts production, and in particular relates to a combined formwork. Background technique [0002] In the production process of modern building prefabricated components, the top five cost components are construction costs, moulds, steel bars, management fees and concrete, which account for nearly 80% of component production costs. Finding ways to reduce the cost of prefabricated components makes assembly Compared with cast-in-place construction, the monolithic structure has a price competitive advantage, which is an urgent problem in the prefabricated construction industry. Because the prefabricated components are produced by special molds, the mold structure is complex, and the special molds cannot be produced universally, resulting in high mold cost, labor costs for simultaneous mold assembly, low construction efficiency, and large investment. The molds are generally customized acc...

Problems solved by technology

Because the prefabricated components are produced by special molds, the mold structure is complex, and the special molds cannot be produced universally, resulting in high mold cost, labor costs for simultaneous mold assembly, low construction efficiency, and large investment. The molds are generally customized according to engineering characteristics. After a certain number of repeated uses It will be scrapped; according to the way of the prior art, the amortization cost of the mold is very high. In addition to improving production efficiency to reduce various amortization costs, if the mold structure can be simplified, generalized, standardized, and the service life can be extended, It can greatly reduce the mold amortization cost of prefabricated components
