Production process of heat preservation prefabricated part

Abstract

The invention belongs to the field of production of building components, and particularly discloses a production process of a heat preservation prefabricated part. The production process comprises the following procedures: (1) pretreatment of a mold; (2) mixing of materials; (3) material arrangement on a concrete layer; (4) pretreatment of a heat preservation layer: galling and / or slotting the heat preservation layer; (5) compounding of the heat preservation layer and a structural layer: putting the heat preservation layer into a mold with materials, enabling the surface, subjected to pretreatment, of the heat preservation layer to be in contact with a concrete layer, and carrying out rolling vibration to enable the heat preservation layer to be compounded on the concrete layer; (6) maintenance; (7) demolding. According to the production process of the heat preservation prefabricated part, by the use of the cohesiveness of concrete in the concrete layer, the heat preservation layer is directly compounded on the structural layer, and the process is simpler; the compounding surfaces of the heat preservation layer and the concrete layer are galled and / or slotted and subjected to rolling vibration, so that slurry in the concrete layer can be embedded into the compounding surface of the heat preservation layer or the formed slots to enhance the adhesion force between the heat preservation layer and the structural layer, and the compounding effect is better.

Description

technical field [0001] The invention belongs to the field of building component production, in particular to a production process of a thermal insulation prefabricated part. Background technique [0002] At present, most of the construction methods in my country still use the manual operation method of on-site pouring, which has a low level of industrialization and low productivity. With the development of construction industrialization, it presents huge economic and social benefits, greatly improving resource utilization efficiency and production efficiency. [0003] For the thermal insulation decorative board, the traditional production method is to compound the thermal insulation board with the structural layer at a later stage. For example, the patent document CN106166794A discloses a prefabricated production line, including a decorative layer production line and a body production line. The decorative layer production line includes production according to prefabricated p...

[0003] For thermal insulation decorative boards, the traditional production method is to compound the thermal insulation board with the structural layer in the later stage. For example, the patent document CN106166794A discloses a prefabricated production line, including a decorative layer production line and a body production line. The decorative layer production line includes production according to prefabricated parts. The pouring molding line, maintenance line, cutting line and post-processing line are arranged in sequence. The post-processing line is equipped with an insulation layer installation station, that is, the insulation layer is the decorative layer and the structural layer. On the layer, the specific operation is to use glue for bonding, but the above-mentioned process is complicated, and at the same time increases the cost. The combination between the structural layer and the composite layer is mainly connected by glue, the reliability is not high, and the glue may be aging. , leaving a security risk
