Concrete casting production technique with energy-saving environmental-protection function

Abstract

The invention relates to production technology for a concrete precast element with energy-saving and environment-friendly functions. In the production of the prior concrete precast element, the fixing of a precast element mould, operators, lifting equipment and raw materials of production are in a motion state, and the production has low efficiency, serious noise pollution, large steam loss, and large energy consumption, and cannot isolate vibrating noise. The technology comprises the following steps: demoulding of a precast element; clearing the inner surface of the mould and spraying mould oil; installing an embedded part and lifting a reinforcement cage; casting concrete and vibrating the concrete; touching the surface of the concrete and clearing the outside surface of the mould; standing and curing; polishing the surface of the concrete; and steam curing. The mould does reciprocating running circularly by current production equipment, and workers, materials and equipment are fixed relatively so as to improve the productivity. The working procedures of vibrating and steam curing are carried out in a fixed station so as to isolate the noise effectively and carry out effective heat insulation on the steam loss and heat loss. The production technology has significant energy conservation and environment protection, and is favorable for popularizing.

Description

technical field [0001] The invention relates to the production field of building materials, in particular to a production process for concrete prefabricated parts with energy-saving and environment-friendly functions. Background technique [0002] The traditional production process of concrete prefabricated parts is that the prefabricated part mold is fixed, and the operators, hoisting equipment and production raw materials are in a state of motion. Due to the relatively heavy weight of concrete prefabricated components, prefabricated components and molds are generally between a few tons and more than ten tons. As a last resort, the molds are placed in different positions in the factory, and sufficient distance is left between the molds. The equipment lifts the steel cage and concrete to the mold, and at the same time, the workers walk to the mold for operation, forming a fixed production factor of the mold, while the other three production factors are constantly running, th...

Due to the relatively heavy weight of concrete prefabricated components, prefabricated components and molds are generally between a few tons and more than ten tons. As a last resort, the molds are placed in different positions in the factory, and sufficient distance is left between the molds. The equipment lifts the steel cage and concrete to the mold, and at the same time, the workers walk to the mold for operation, forming a fixed production factor of the mold, while the other three production factors are constantly running, that is, the operators, lifting equipment and raw materials all move back and forth, making Low production efficiency

Since the mold is placed in different parts, the vibration noise cannot be isolated; the noise generated during concrete molding will cause great pollution to the environment

Under the conditions of this production mode, the steam curing of the mold can only be made of relatively soft materials such as canvas as a curing cover, which will cause a lot of steam loss and consume a lot of energy.
