Embodiment Construction

[0024] Attached below Figure 1~4 The specific implementation manner of the height-adjustable prefabricated laminated floor slab of the present invention is described.

[0025] As shown in the drawings, a height-adjustable fabricated laminated floor slab of the present invention includes angle steel 1 , steel bar truss 2 , L-shaped screw rod 3 , concrete 4 and nut 5 .

[0026] Angle steel 1, concrete 4 and steel bar truss 2 are combined and poured into component A1, and the production of A1 is completed in the factory; steel bar truss 2 is distributed at the bottom of component A1 as stress reinforcement; two angle steel 1 are arranged on the prefabricated slab along the direction of the beam holes on the angle steel 1 before pouring; during pouring, a hole of the same size is reserved on the position corresponding to the opening of the angle steel 1 on the component A1; hole on A1, and tighten the lower part of component A1 through nut 5, the cross bar is hung on the upper s...

Abstract

A height-adjustable fabricated composite floor slab comprises angle steel, steel bar trusses, L-shaped screw rods, concrete and nuts. A component A1 is composed of the angle steel, the concrete and the steel bar trusses jointly, and holes are reserved in the component A1 when the hole-forming corresponding positions of the angle steel are poured; a prefabricated plate is manufactured in a factoryand assembled on site in a lifted mode; transverse rods of the L-shaped screw rods are hung on the upper surface of a steel girder, and vertical rods penetrate through the holes in the component A1 and are screwed through the nuts; after lifting, the height of the prefabricated plate can be adjusted by adjusting the nuts on the L-shaped screw rods, the relative positions of floor slab bodies and the steel girder are adjusted, and it is guaranteed that the lower surfaces of all the floor slab bodies are flush; through the connecting mode, part of the girder depth is hidden, and thus the structural spatial arrangement is more flexible and attractive; the adhesive force of new and old concrete layers is increased through the steel bar trusses in the component A1, and the overall performance of the composite floor slab is improved; and the component A1 and the girder are lifted on site through the L-shaped screw rods and the nuts, and the height-adjustable fabricated composite floor slab conforms to the concept of assembly-type buildings.

Description

technical field [0001] The invention belongs to the field of building structural components and is suitable for fabricated steel structure buildings. Background technique [0002] In the case of a large excess of steel production in my country every year, the country has implemented a series of policies and guidelines to promote the use of steel in building structures, and vigorously develop steel structure buildings. Steel structures are developing rapidly due to their light weight, good plasticity and toughness, and good seismic performance. The assembled steel structure system that has emerged has the advantages of fast construction speed, less construction pollution, and easy quality assurance. It is a "green" Construction is suitable for the development of China's construction industry and makes my country's construction industry return to industrialization. [0003] Precast concrete laminated floor slab refers to an assembled integral floor slab formed by superimposing...
