Combined steel die for highway prefabricated concrete member

Abstract

The invention discloses a combined steel die for a highway prefabricated concrete member. The combined steel die comprises steel die tables which are fixedly provided with die cavities, and each die cavity is internally provided with a plurality of inner membranes; and each inner membrane comprises a stereotyping diaphragm installed removably, and the outer side of each steel die table is providedwith lifting rods. The combined steel die has the beneficial effects that the multi-cavity combined die is adopted, and adjustable temporary templates are arranged for the die cavities so that the die has the ability of producing various prefabricated blocks of different models; the problem of difficult demoulding is solved, so that the turnover rate of the templates is improved; the prefabricating speed of members is increased, and the combined steel die has the advantages of the simple structure, easy operation and good effect; concrete construction production links are optimized, and the labor consumption can be reduced effectively; and the cost amortization is reduced, and the utilization rate of the die for machining small members is improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a composite steel mold used for expressway assembled concrete components. Background technique [0002] With the rapid development of the national economy and the accelerated pace of structural adjustment of my country's mold industry, the development of molds tends to be more and more large-scale and precise. On the one hand, most of the existing small-scale prefabricated component molds use a single plastic mold, the formwork utilization rate is low, and steam curing cannot be performed, and the concrete strength is slow to increase. On the other hand, the prior art cannot realize mechanized production, and requires a large amount of labor, resulting in a waste of labor. The main problems are as follows: 1. The single mold method is inefficient, has a high labor occupation rate, and is not suitable for large-scale production; 2. The single mold method is not suitable for large-...

AI Technical Summary

Problems solved by technology

On the one hand, most of the existing small prefabricated component molds use a single plastic mold, the utilization rate of the formwork is low, and steam curing cannot be performed, and the concrete strength is slow to increase

On the other hand, the existing technology cannot realize mechanized production and requires a lot of labor, resulting in a waste of labor

The main problems are as follows: 1. The single mold method has low efficiency and high labor occupancy rate, and is not suitable for large-scale production; 2. The single mold method is not suitable for large-scale production prefabrication, and product quality cannot be guaranteed
