Novel large-span ribbed beam laminated slab and construction method

Abstract

The invention relates to a novel large-span ribbed beam laminated slab and a construction method, and belongs to the field of building construction. The novel large-span ribbed beam laminated slab comprises a prefabricated slab arranged between two cross beams, a laminated concrete layer is arranged on one face of the prefabricated slab, a plurality of main ribbed beams are arranged on the other face of the prefabricated slab, and the two ends of each main ribbed beam are connected with the two cross beams correspondingly. The construction method comprises the steps that S1, the prefabricated slab is lifted to the positions above the two cross beams; S2, after the main ribbed beams are aligned with embedded parts, the prefabricated slab is put down, the main ribbed beams are embedded in the embedded parts, and then the main ribbed beams and the cross beams are welded; and S3, concrete is poured on the face, away from the main ribbed beams, of the prefabricated slab and the tops of stand columns, and the concrete forms the laminated concrete layer to achieve forming and mounting of the large-span ribbed beam laminated slab. According to the novel large-span ribbed beam laminated slab and the construction method, the effects of improving the structural stability of the laminated slab and reducing the mounting difficulty are achieved.

Description

technical field [0001] The application relates to the field of building construction, in particular to a novel large-span rib-beam laminated slab and a construction method. Background technique [0002] With the continuous advancement of construction technology, people can continuously expand the building space, making the architectural design of large span and large bay more and more widely used, and the architectural design of large span and large bay often uses laminated panels. The laminated slab is characterized by high rigidity, good seismic performance, and a relatively simple manufacturing method. [0003] The laminated slab is an assembled integral floor slab composed of prefabricated slabs and cast-in-place reinforced concrete layers. When installing a laminated slab, the laminated slab is generally connected between two beams. For large-span buildings, the length of the laminated slab produced Longer, in the actual construction, it is found that the long laminate...

Problems solved by technology

[0003] The laminated slab is an assembled integral floor slab composed of prefabricated slabs and cast-in-place reinforced concrete layers. When installing a laminated slab, the laminated slab is generally connected between two beams. For large-span buildings, the length of the laminated slab produced Longer, in the actual construction, it is found that the long laminated board is easy to bend after installation and use, so people need to divide the laminated board into multiple parts, and then connect multiple laminated boards when installing the laminated board, so as to maintain The structure of the laminated board is stable, but this will increase the difficulty of installation and increase the cost
