Description
Technical Field
The utility model relates to a truss reinforced concrete composite slab, and belongs to the technical field of building structures.
Background
The building industrialization has become the inevitable trend of the development of the building industry in China, the cast-in-place building mode is changed into the assembly integral type building mode of prefabricating in factories and assembling on site, and the method has become the mission of modern building practitioners. At present, the laminated floor slab mainly comprises a common flat plate type prestressed concrete laminated floor slab, a prefabricated ribbed prestressed concrete laminated slab and a truss reinforced concrete laminated slab.
The traditional method of the truss reinforced concrete composite slab is to directly select a drawing set, and mainly facilitates the arrangement of trusses so as to improve the production efficiency of members. But has the disadvantages that the reinforcing steel bars of the drawing set are not strictly arranged according to the stress direction of the bidirectional plate blocks; the cross section height of the truss used by the method of the laminated slab with the same thickness is lower, so that the pipeline is not beneficial to the later-stage cast-in-place laminated slab surface equipment penetration.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the reinforced concrete composite slab of the truss, which improves the height of the cross section of the truss to bring convenience to the pipe arrangement in site construction.
The utility model is realized by the following technical scheme:
a truss reinforced concrete laminated slab comprises a prefabricated slab, wherein a first steel bar group and a second steel bar group which are perpendicular to each other are arranged in the prefabricated slab, two sides of the first steel bar group and two sides of the second steel bar group extend out of the prefabricated slab, and the second steel bar group is positioned below the first steel bar group; the prefabricated slab is further provided with a truss rib, and the bottom of the truss rib and the second steel bar group are in the same plane.
The first steel bar group comprises a plurality of first steel bars, one side of each first steel bar is provided with a bent portion, and an angle between each bent portion and each first steel bar is 135 degrees.
According to the truss reinforced concrete composite slab, the protruding part of one side, provided with the bent part, of the first reinforcing steel bar is longer than the protruding part of the other side of the first reinforcing steel bar.
The truss reinforced concrete composite slab comprises truss upper chord ribs, web ribs and truss lower chord ribs which are sequentially connected, wherein the web ribs are symmetrically arranged on two sides of the upper chord ribs.
According to the truss reinforced concrete composite slab, the cross section of each truss rib is triangular.
According to the truss reinforced concrete composite slab, the second steel bar group comprises second steel bars, and the lengths of the parts of the two sides of the second steel bars, which extend out of the prefabricated slab, are the same.
The utility model achieves the following beneficial effects:
according to the laminated slab, the second steel bar group is arranged below the first steel bar group, and the bottom of the truss and the second steel bar group are in the same plane, so that the requirement that bottom bars of the laminated slab are arranged according to the stress direction of the plate is met, and the cross section height of the truss can be increased to bring convenience to the pipe arrangement in site construction.
