Assembled superimposed sheet construction hoist and mount system

Technical Field

The invention relates to the technical field of construction and hoisting of laminated slabs, in particular to an assembly type construction and hoisting system for laminated slabs.

Background

The traditional construction process is cast-in-place reinforced concrete, and is finished by template building, reinforcing steel bar laying and concrete pouring, because a pouring method is adopted completely, a large amount of templates and concrete need to be used, the consumed materials are excessive, and the environmental pollution is serious at the same time, so that the laminated slab is pushed out at the present stage and is made of environment-friendly materials, and after the laminated slab is used, the use of the templates can be reduced, the laminated slab is used as a partial bottom plate for pouring, and meanwhile, because the reinforcing steel bars are also arranged in the laminated slab, the laminated slab can replace a part of concrete as a construction material, namely, the template materials are reduced, and the concrete consumption is also reduced.

The laminated slab is produced in batches according to specifications by a factory, then is transported to a construction site by a truck for hoisting, a tower crane hook is manually hooked on a keel of the laminated slab, the laminated slab is transported to a floor needing to be installed by a tower crane, a template is installed on the floor, the part of the laminated slab needing to be installed is hollowed out, the template is not installed, only a mold table capable of placing the laminated slab is built, after the laminated slab is transported to the floor by the tower crane, the laminated slab is positioned by naked eyes, meanwhile, the laminated slab slowly falls on the mold table by matching with the tower crane, during the operation of the tower crane, even if the tower crane works under the condition of manual assistance, the work is unstable, so that the position of the laminated slab deviated from the mold table is more, manual adjustment is needed by manually using a crowbar, and the construction hoisting work flow is only completed, hoist and mount superimposed sheet process, the superimposed sheet needs to remain partial volume and is located outside the moulding platform, a concrete contact that is used for making the superimposed sheet can with the present pouring mixes, and when installing the superimposed sheet, the workman can't make superimposed sheet and moulding platform parallel and level fast, the superimposed sheet stretches out the moulding platform part simultaneously and is not conform to the specification, can lead to superimposed sheet and concrete mix the place inadequately too seldom, drop easily, consequently, it is in the settlement scope to guarantee that the superimposed sheet stretches out the moulding platform position at hoist and mount superimposed sheet process, otherwise need to measure hoist and mount again or need the manual work to carry out a lot of regulation to the superimposed sheet position, so not only increase staff's work load, when surveying hoist and mount superimposed sheet again, the superimposed sheet still has the risk that drops, cause the incident easily.

Therefore, in order to enable the laminated slab to be parallel and level quickly, the extending part is guaranteed to be in the set range, the workload of workers is reduced, the hoisting working efficiency is improved, and the assembled laminated slab construction hoisting system is provided.
