Description

Production process of heat-insulation prefabricated member

Technical Field

The invention belongs to the field of building component production, and particularly relates to a production process of a heat-insulation prefabricated member.

Background

At present, the building construction mode of China mostly adopts a manual operation mode of cast-in-place, and the building construction method has low industrialization level and low production rate. With the development of building industrialization, huge economic benefits and social benefits are presented, and the resource utilization efficiency and the production efficiency are greatly improved.

In the prior art, in the production line of concrete prefabricated members, maintenance is an indispensable production process, in the flow of prefabricated member maintenance, especially in the in-process of pre-maintenance, generally pile up neatly the mould that will pour on the transportation line and push the maintenance kiln in through the track on the pile up neatly frame and maintain, or directly pile up neatly and maintain on the support frame of maintenance kiln, these two kinds of pile up neatly modes are comparatively complicated, need to carry out strict operation control to the pallet truck, in the mode of adopting the pile up neatly frame to push maintenance in the maintenance kiln in addition, the pile up neatly frame is very easily rusted under the condition of maintenance kiln high humidity, high temperature for a long time, the complexity of maintenance kiln has undoubtedly been increased to the latter mode, increase its construction cost, increased the maintenance cost of maintenance kiln simultaneously. In addition, the curing of the concrete prefabricated member in the prior art usually includes two curing processes, for example, patent CN101508144B discloses a production process of the concrete prefabricated member with energy-saving and environmental protection functions, the curing process includes static curing and steam curing in a steam chamber; patent document CN106166794A discloses a preform production line, the curing line of the production line comprises a pre-curing kiln and a final curing kiln, and the pre-curing kiln and the final curing kiln are connected through a transfer line; the maintenance method not only has complex maintenance process, but also has larger energy consumption.

therefore, it is urgently needed to develop a production process of prefabricated parts, which is energy-saving, production cost-saving, simple in process flow and small in occupied area.

Disclosure of Invention

The invention aims to provide a production process of a prefabricated part, which is energy-saving, production cost-saving, simple in process flow and small in occupied area.

The above purpose is realized by the following technical scheme: a production process of a heat-insulating prefabricated member comprises the following steps: (1) pretreatment of the mold: at least comprises the step of cleaning the mould; (2) mixing the ingredients: weighing the components in the raw materials according to a proportion, uniformly mixing, and uniformly mixing and stirring the raw materials and water, wherein the raw materials at least comprise cement and fine aggregate; (3) material distribution: pouring the mixture obtained by uniformly stirring the raw materials and water in the step (2) into the mould treated in the step (1), and vibrating uniformly to form a concrete layer; (4) setting of the heat preservation layer: placing the heat-insulating layer in the mould after the material is distributed, and compounding the heat-insulating layer on the upper part of the concrete layer; (5) and (5) maintenance: stacking the moulds subjected to the step (4), forming relatively independent and closed maintenance spaces between a bottom mould and side moulds of the moulds and the heat insulation layer on the bottom mould, and performing heat insulation and moisture preservation maintenance on the concrete layer by utilizing the heat insulation performance of the heat insulation layer and the hydration heat generated during the hydration of the concrete; (6) and (6) demolding.

The invention is different from the conventional mode that the structural layer and the insulating layer are bonded by using the adhesive in the post-treatment operation process after the maintenance is finished, and after the structural layer is poured, the structural layer concrete is directly bonded on the insulating layer composite structural layer by using the cohesiveness of the structural layer concrete, so that the process is simpler and the composite effect is better. Meanwhile, the maintenance mode adopted in the invention is carried out after the heat-insulating layer is compounded on the structural layer, the heat loss in the maintenance space is reduced by utilizing the heat-insulating property of the heat-insulating layer, the heat energy utilization rate is improved, the hydration heat of the prefabricated member is fully utilized to maintain the prefabricated member in the constant-temperature maintenance space, and the maintenance effect is improved.

The production process of the heat-preservation prefabricated member as claimed in claim 8, wherein guide rails are arranged on the conveying lines which are connected in parallel, the molds move along the guide rails through a transmission device, and the molds on the conveying lines which are connected in parallel are operated in a staggered mode; and the first extruding mechanism and/or the second extruding mechanism reciprocate between the conveying lines which are connected in parallel to distribute the materials.

11. The production process of the heat-preservation prefabricated member as claimed in claim 4, wherein the step (4) is followed by a step of arranging a back bolt: the back bolt extends into the decorative layer from the heat insulation layer through the grabbing piece, and the slurry of the decorative layer and the structural layer tightly wraps the back bolt through vibration of the vibration device.

12. The production process of the heat-preservation prefabricated member as claimed in claim 11, wherein the step (6) is followed by a prefabricated member post-treatment process, and the prefabricated member post-treatment process at least comprises the steps of shot blasting or surface treatment, film coating, cutting, grooving and packaging.
