A new type of large-span rib beam composite plate and construction method

Abstract

The application relates to a novel large-span rib-beam composite board and a construction method, belonging to the field of building construction. A new large-span rib-beam composite board includes a prefabricated board arranged between two beams, and one side of the prefabricated board is provided with A number of main rib beams are arranged on the other side of the superimposed concrete layer, and the two ends of the main rib beam are respectively connected with two beams; the construction method is: S1. Lift the prefabricated plate to the top of the two beams; S2. After the rib beam is aligned with the embedded parts, put down the prefabricated plate, so that the main rib beam is embedded in the embedded part, and then weld the main rib beam and the cross beam; S3. Pour concrete on the side of the prefabricated plate away from the main rib beam and the top of the column, The concrete forms a superimposed concrete layer to realize the forming and installation of a large-span rib-beam superimposed board; the present application has the effects of improving the structural stability of the superimposed board and reducing the difficulty of installation.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a novel large-span rib-beam composite board and a construction method. Background technique [0002] With the continuous progress of construction technology, people can continue to expand the building space, so that the architectural design of large span and large bay is more and more widely used, and the architectural design of large span and large bay often uses laminated board, The characteristics of the laminated board are high rigidity, good seismic performance, and a relatively simple production method. [0003] Laminated slabs are prefabricated slabs and cast-in-place reinforced concrete laminates that are assembled together. When installing laminated slabs, the laminated slabs are generally connected between two beams. For large-span buildings, the length of the laminated slabs produced In actual construction, it is found that the laminated board with a lon...

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
