Problems solved by technology

[0002] At present, ordinary prefabricated reinforced concrete slabs, densely ribbed slabs, and unbonded prestressed slabs are widely used in building structure engineering. However, ordinary prefabricated concrete slabs have small spans, poor integrity, and poor seismic performance; densely ribbed slabs and Unbonded prestressed slabs have a long construction period, complex process, high cost, and poor thermal insulation and sound insulation effects

Embodiment Construction

[0014] Now further illustrate how the present invention is implemented in conjunction with accompanying drawings:

[0015] The invention is a box-type prestressed concrete light composite slab, which is composed of an upper cast-in-place concrete slab S and a lower reinforced concrete prefabricated slab X. The lower reinforced concrete prefabricated slab X is a closed prefabricated slab composed of a reinforced concrete bottom layer, a lightweight filled core layer and a concrete outer layer, such as Figure 5 . The reinforced frame of the reinforced concrete bottom layer 1 is composed of common steel bars and prestressed steel bars. The common steel bars are: there are П-shaped vertical end horizontal steel bars 6 arranged at longitudinal intervals, and the encrypted horizontal steel bars 7 are distributed at both ends of the longitudinal direction. The common longitudinal steel bars 4 are used The tensioning device is arranged between the lightweight filling core block 2 an...

Abstract

The invention discloses a box type prestress concrete light composite slab and belongs to the field of building components. The box type prestress concrete light composite slab is composed of an upper cast-in-place concrete slab and a lower reinforced concrete prefabricated slab. A reinforced concrete bottom layer of the lower reinforced concrete prefabricated slab is composed of a rebar framework and pouring concrete. The rebar framework is composed of prestress rebar and common rebar. Common transverse rebar is distributed on the lower layer. Longitudinal rebar is arranged on the two sides. Prestress steel is longitudinally arranged on the transverse common rebar. A soft filling core layer is composed of light filling core blocks which are transversally spaced and transverse concrete ribs and is arranged on the surface of the reinforced concrete bottom layer. A closed lower reinforced concrete prefabricated slab is formed by pouring concrete on the periphery and the top face of the light filling core. The box type prestress concrete light composite slab is formed after the upper cast-on-site concrete slab is poured on the surface of the lower reinforced concrete prefabricated slab. The box type prestress concrete light composite slab is reduced in self-weight, improves structural integrity and the overall earthquake resistance, and can meet the requirements of large-span buildings.

Description

technical field [0001] The invention relates to a box-type prestressed concrete light laminated board, which belongs to the field of building components. Background technique [0002] At present, ordinary prefabricated reinforced concrete slabs, densely ribbed slabs, and unbonded prestressed slabs are widely used in building structure engineering. However, ordinary prefabricated concrete slabs have small spans, poor integrity, and poor seismic performance; densely ribbed slabs and Unbonded prestressed slabs have a long construction period, complex process, high cost, and poor thermal insulation and sound insulation effects. Therefore, relevant parties have been devoting themselves to the development of lightweight infill composite panels with good seismic resistance and integrity, and suitable for large-span buildings. Contents of the invention [0003] The purpose of the present invention is to provide a box-type prestressed concrete light-duty laminated slab, which can ...
