Prefabricated plate manufacturing, hoisting and secondary pouring integrated device and construction method

Abstract

The invention relates to the technical field of assembled buildings, and particularly relates to a prefabricated plate manufacturing, hoisting and secondary pouring integrated device and a construction method. The device comprises a die table, supports and brackets. The die table is provided with a plurality of positioning grooves. The corresponding bracket is placed in each positioning groove. Each bracket is detachably connected with the corresponding support. When concrete is poured on the die table and prefabricated plates are formed, the supports and the prefabricated plates are poured into a whole. When a plurality of die tables are stacked, the supports can be used for supporting the upper-layer die table. When the multiple prefabricated plates are stacked, the supports can be usedfor supporting the upper-layer prefabricated plate. When the prefabricated plates are subjected to secondary pouring, cast-in-place layer concrete, the supports and the prefabricated plates are pouredinto a whole. By means of the prefabricated plate manufacturing, hoisting and secondary pouring integrated device and the construction method, large-batch plane production or three-dimensional production of the concrete prefabricated plates can be achieved, and the safe and reliable continuous operation process of storage, transportation and hoisting is achieved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to an integrated device and construction method for manufacturing, hoisting and secondary pouring of prefabricated panels. Background technique [0002] With the rapid development of my country's construction industrialization process, the demand for concrete laminated floor slabs is increasing. Composite floor slabs include factory prefabricated bottom slabs and on-site secondary pouring layers, which are indispensable horizontal prefabricated components in the field of prefabricated buildings. The prefabricated slab is made of truss steel bars, steel mesh, and concrete pouring, with a general thickness of 50-80mm. The existing devices and methods involving production, storage, transportation, hoisting and secondary pouring at home and abroad: [0003] Production of laminated slab bottom plate: production of flat formwork, when the product is demoulded...

AI Technical Summary

Problems solved by technology

The defects of laminated base plate production are: flat production, low efficiency, and large floor space; three-dimensional production, high requirements for mold tables, and high overall cost; product demoulding is easy to damage: the base plate is very thin, there are few lifting points for demoulding, and the force is large , it is very easy to cause the hanging point to fall off; the cost of setting up more embedded hanging points will increase

[0007] The above two methods: either press the truss reinforcement or the concrete sheet, both of which will cause damage to the component; the stacking height is limited to 4-6 layers, the product occupies a large area, and it is difficult to transport it; the board is pressed, and the damage rate in the transportation link is extremely high.

[0008] Laminated slab floor hoisting: The hoisting point is generally a truss steel bar or a pre-embedded hoisting point, which is generally dragged and pulled. The disadvantages of this method are:

The defect of secondary pouring of laminated slabs is: there is no reference point, and the total height of laminated slabs (thickness of prefabricated slab + thickness of cast-in-place layer) is difficult to control; it will either cause material waste (too thick) or cause safety hazards (too thin)
