Production line for concrete prefabricated piece

Abstract

The invention belongs to the field of building part production and particularly discloses a production line for a concrete prefabricated piece. The production line comprises a mould pretreatment station, a material distribution station, a mould combination station and a demoulding station. The mould combination station is used for stacking and combining moulds after material distribution is completed, connecting portions are arranged at the bottoms and on the upper portions of the moulds, and the vertically-arranged moulds are fixed through the connecting portions. An independent curing space is formed between the vertically-arranged moulds, and the prefabricated piece is cured in the curing space. According to the production line for the concrete prefabricated piece, a curing kiln or other curing rooms are not needed in the curing link, only the moulds are conveyed to stock dump after being stacked and combined, and demoulding can be conducted after curing is conducted for a certain time; the technological process is simplified, a stacking frame or other supports are not needed in the curing process, and production efficiency is improved while production cost is reduced; and meanwhile, due to the fact that the curing kiln and the like does not need to be used, cost is reduced, energy consumption is lowered, maintenance cost of facilities is reduced, and the occupied area of the whole technological production line is greatly reduced.

Description

technical field [0001] The invention belongs to the field of building component production, in particular to a production line for concrete prefabricated parts. Background technique [0002] At present, most of the building construction methods in our country still use the manual method of pouring on site, which has a low level of industrialization and low productivity. With the development of construction industrialization, it has shown huge economic and social benefits, greatly improving resource utilization efficiency and production efficiency. [0003] In the prior art, in the production line of concrete prefabricated parts, curing is an indispensable production process. In the process of prefabricated parts curing, especially in the process of pre-curing, the poured concrete is usually placed on the transportation line. The molds are stacked on the palletizing frame and pushed into the curing kiln through rails for curing, or they are directly stacked on the support fr...

[0003] In the prior art, in the production line of concrete prefabricated parts, curing is an indispensable production process. In the process of prefabricated parts curing, especially in the process of pre-curing, the poured concrete is usually placed on the transportation line. The molds are stacked on the palletizing frame and pushed into the curing kiln through rails for curing, or they are directly stacked on the support frame of the curing kiln for curing. These two palletizing methods are more complicated and require strict operation of the palletizing truck. In addition, the palletizing rack is pushed into the curing kiln for maintenance. The palletizing rack is easily corroded under the conditions of high humidity and high temperature in the curing kiln for a long time. The latter method undoubtedly increases the complexity of the curing kiln and increases the Its construction cost increases the maintenance cost of the curing kiln at the same time

In addition, the maintenance of concrete prefabricated parts in the prior art usually includes two maintenance processes. For example, patent CN101508144B discloses a production process of concrete prefabricated parts with energy-saving and environmental protection functions. The maintenance process includes static maintenance and steam curing in a steam chamber; Patent document CN106166794A discloses a prefabricated part production line, the curing line of the production line includes a pre-curing kiln and a final curing kiln, and the pre-curing kiln and the final curing kiln are connected by a transfer line; the above-mentioned curing method is not only complicated in the curing process , and the energy consumption is large
