Problems solved by technology

[0004] When hoisting prefabricated slabs, hooks are usually connected to the upper chord reinforcement of the steel truss protruding from the prefabricated slab to lift the prefabricated slab, but to ensure the quality of the lifting, the on-site personnel need to connect as many hooks as possible to different steel trusses , the number of steel trusses on the prefabricated slab is laid according to the design, and there are corresponding spacing requirements between two adjacent steel trusses. Increasing the number of steel trusses will change the failure form of the laminated slab into brittle failure. Therefore, when the number of steel trusses on the prefabricated slab is not When meeting the hoisting requirements, it will increase the difficulty of transportation and installation of prefabricated panels

Embodiment Construction

[0036] The following is attached Figure 1-6 The application is described in further detail.

[0037] The embodiment of the present application discloses a prefabricated floor structure. refer to figure 1 , the prefabricated floor structure includes a prefabricated slab 1 connected to a support frame 2 on the upper surface of the prefabricated slab 1 . The prefabricated slab 1 is in the shape of a rectangle, and several steel bar trusses protruding from the upper surface of the prefabricated slab 1 are formed on the prefabricated slab 1. In the implementation of this application, two steel bar trusses are arranged at intervals along the width direction of the prefabricated slab 1. The length of the steel bar truss The direction is set parallel to the length direction of the prefabricated slab 1 .

[0038] In the implementation of this application, there are two support frames 2 parallel to the length direction of the steel bar truss at intervals, each support frame 2 includ...

Abstract

The invention relates to a fabricated floor structure. The fabricated floor structure comprises a prefabricated slab and a plurality of supporting frames connected to the upper surface of the prefabricated slab. Each supporting frame comprises connecting units and hoisting ribs, wherein at least two sets of connecting units are arranged in the direction parallel to the length direction of a steel bar truss at intervals, each connecting unit comprises two connecting ribs fixed to the prefabricated slab and an abutting rib connected between the two connecting ribs, and the abutting rib is connected with the connecting ribs through height adjusting parts; and the hoisting ribs are connected to the abutting ribs. The fabricated floor structure has the effects that the load borne by the steel bar truss during hoisting is reduced, and thus the probability of bending deformation of the steel bar truss during transportation and hoisting of the prefabricated slab is decreased.

Description

technical field [0001] The present application relates to the technical field of floor construction, in particular to an assembled floor structure. Background technique [0002] At present, the prefabricated floor slab refers to the floor slab that is poured in the factory, then transported to the site, and assembled by lifting equipment. [0003] The prefabricated floor slab is usually a laminated floor slab, that is, the prefabricated slab is prefabricated in the factory, then lifted to the site, and then a concrete layer is cast on the upper surface of the prefabricated slab, and the prefabricated slab is passed between the concrete layer and the prefabricated slab. The steel trusses above form the connection. The cross-section of the steel truss is triangular and the bottom end is pre-embedded in the prefabricated slab, and the top of the steel truss protrudes from the prefabricated slab and extends into the concrete layer. [0004] When hoisting prefabricated slabs, h...
