Assembled laminated floor slab and its construction method based on tool-type hanging formwork

Abstract

The invention relates to an assembled composite floor slab based on tool type template lifting. The assembled composite floor slab comprises a composite floor slab shaping supporting system, a composite floor slab cast-in-situ belt template lifting system, a composite floor slab and beam connecting structure and a composite floor slab and wall connecting structure, the composite floor slab shapingsupporting system comprises an adjustable lifting beam, a prefabricated floor slab and independent supports, limiting screws are pre-embedded on a lower floor slab, the independent supports are erected among the limiting screws and comprise frame grid plate bases lower vertical rods, sleeving connection type upper vertical rods, protection frames and tool beams from bottom to top, the prefabricated floor slabs are hosted to tool beams of the independent supports by the adjustable lifting beam and adjusted flat by fine-adjustable supporting seats at the bottoms of the protection frames, and ahoisting rope is arranged on the adjustable lifting beam. The composite floor slab has the advantages that a unit-type adjustable shaping supporting system replaces a traditional independent steel support, the fine-adjustable supporting seats are additionally arranged, construction errors of the composite floor slab can be reduced, and deformation in the construction stage of a laminated cast-in-place layer is decreased.

Description

technical field [0001] The invention relates to an assembled laminated floor slab based on a tool-type hanging formwork and a construction method, which belongs to the field of main structure engineering and is suitable for the construction of laminated floors in an assembled integral shear wall structure. Background technique [0002] At present, the traditional housing construction mode is gradually developing into an industrialized construction mode, further realizing standardization, scale, industrialization and assembly. Reinforced concrete floor slabs are the main components of house construction. For the floor slabs, laminated slabs can be constructed in the way of prefabrication to the greatest extent, which represents the development direction of the national construction industrialization and is conducive to effectively reducing the waste of resources and waste of formwork materials such as plywood. It saves labor. It combines in-depth design technology and modern ...

Problems solved by technology

[0003] However, the deformation of the prestressed PK slab during the construction process of the laminated floor during transportation, stacking, hoisting and the construction of the laminated cast-in-place layer will affect the normal use of the laminated floor

At the same time, due to the lack of mechanical research on the construction process of prestressed PK slab laminated slabs and the lack of theoretical guidance in the construction process, there is blindness in the formulation, implementation and inspection of construction plans, especially the support system of laminated slabs and cast-in-place beams , The detailed processing of wall nodes has a large room for optimization
