A series mould table device and production process for three-dimensional production of precast concrete slabs

technical field

The invention belongs to the technical field of prefabricated construction engineering, and particularly relates to a series mold table device and a production process for three-dimensionally producing precast concrete slabs.

Background technique

Vigorously developing prefabricated buildings is the basic direction of my country's construction industry upgrading. The consumption of prefabricated concrete components, especially floor slabs and wall panels, is increasing. The traditional production processes and methods not only have large investment, low efficiency, and energy consumption, but their production capacity is increasingly unable to meet market demand.

The formwork table is the production platform of concrete prefabricated components. The main beam of the mold table is the main force-bearing member of the entire mold table, which is responsible for ensuring the smoothness and stability of the entire mold table, and transfers the load of the entire mold table to the ground foundation. The sub-beam of the mould table ensures that the mould table panel is flat and stable, and transmits all the loads on the mould table panel to the main beam of the mould table. The formwork panel is the operating surface for making concrete prefabricated components, and is generally made of hard and smooth materials such as steel plates to ensure that the surface of the concrete prefabricated components is smooth and flat.

The existing mold table forms are: fixed mold table and assembly line mold table.

The fixed mold table is laid directly on the ground, that is, the main beam of the mold table touches the ground and remains stationary. The fixed mold table is produced by tiling: the mold table is laid flat in the workshop and fixed. Basic process: After the mold is poured, it is maintained on site, and the finished product is hoisted in-situ piece by piece. The defect is: the main beam of the formwork table is directly in contact with the ground foundation. If the ground is not flat, it is easy to cause the main beam to be twisted and affect the accuracy of the components; the formwork table cannot be stacked: the main beam will be deformed by layer-by-layer pressure, and it is more likely to be distorted in contact with the ground. Deformation; large floor space, large capital investment, low production efficiency, and large demand for personnel; single-layer plane maintenance, high energy consumption, flat lay production, difficult transfer of materials and finished products; mixed personnel, materials, and equipment, great potential safety hazards, and workshops The space is not used in any way.

The main beam of the die table of the assembly line is placed on the track and runs on the track through the movable pulley. Flat die assembly line production: place the die table on the track, the production station personnel do not move, the die table moves on the track, and is lifted to a centralized point for maintenance through its complicated mechanical device. The disadvantage is: the mold table cannot be stacked, and the mold table is held up by the bracket structure during centralized maintenance, that is, the upper and lower mold tables are not in contact, otherwise it will be deformed. High requirements for workshops and infrastructure, large investment, long construction period, high investment in production equipment, long installation period, complex electronic control equipment, high requirements for operators, and large production area; serious unreasonable maintenance of components: products produced in different periods Maintenance in the same maintenance area not only consumes a lot of energy, but also cannot guarantee the quality of the product; the mold table can only move in a plane, and it can only move in the specified route, the space cannot be used reasonably, and the production efficiency is low; single-line assembly operation, once arbitrary If there is a problem in the link, the entire production line will be blocked, the material will be organized, the finished product transportation line will be too long, the efficiency will be low, and the waste will be serious.
