Abstract
The invention provides a section steel plate rib concrete composite floor slab, and belongs to the field of building structures. The section steel plate rib concrete composite floor slab is formed by a prefabricated bottom board and a cast-in-place concrete layer. The prefabricated bottom board is formed by a lower reinforced concrete layer, transverse steel ties, light padding blocks and section steel plate longitudinal ribs. Longitudinal prestressed steel bars and saddle-shaped transverse steel bars are arranged on the lower reinforced concrete layer of the prefabricated bottom board at intervals. The two section steel plate longitudinal ribs are arranged in the longitudinal direction of the inner sides of the two ends of the transverse steel bars. Perforations in the lower portions of the section steel plate longitudinal ribs are correspondingly fixed with end openings of the transverse steel bars in a clamping mode respectively. The transverse steel ties and the light padding blocks are arranged on the surface of the lower reinforced concrete layer according to set parallel intervals to form the prefabricated bottom board. A solidly integrated composite floor slab is formed as long as the cast-in-place concrete layer is arranged on the prefabricated bottom board. According to the design, the prefabricated bottom board has the advantages of being low in weight, good in integrality, strong in deformation resistance performance, large in applicable transverse span, good in heat preservation and sound insulation performance, capable of being produced on an industrialized scale, and high in production efficiency.
Description
Technical field
A kind of shaped steel steel plate of the present invention rib reinforced concrete slab belongs to building structure field.
Background technology
At present, the concrete floor in the building field is divided into Bars In Poured Concrete Slab, precast plate and traditional laminated floor slab three types.The cast-in-place part of tradition laminated floor slab and the globality that pre-erection combines Bars In Poured Concrete Slab are by force and the saving of precast plate is supported and the advantage of template, use more and more extensive, wherein especially more common with the concrete rib laminated floor slab in engineering.
Existing concrete rib laminated floor slab is with vertical rib and the cross rib of steel concrete as laminated floor slab, and intercostal is hollow or is filled with the light filling piece, alleviates deadweight.For guaranteeing the transverse integral between plate and the plate, often need indulge perforate on the rib at concrete, perhaps keep somewhere the beard muscle, but it is comparatively complicated to open transverse holes technique at the vertical rib of plate, is difficult to realize, and is unfavorable for factory's streamlined production.Anti-shearing concrete area in the concrete rib laminated floor slab cross section is less, so that the shear strength between preformed layer and in-situ layer is relatively poor, enough shear reinforcements need be set satisfies the shearing resistance requirement, and the reinforcing bar configuration is more, and the reinforcing bar binding amount is larger.
For this reason, from solving the existing limitation problem of reinforced concrete laminated floor slab, further further investigation and exploitation replace the Novel superposed floor of the reinforcing bar in the concrete rib with the shaped steel steel plate, improve the performance of floor aspect vertical span and horizontal coupling stiffness, improve overall performance and the batch production level of floor, become the common problems of concern of industry.
Summary of the invention
The purpose of patent of the present invention provides a kind of shaped steel steel plate rib reinforced concrete slab, improves the reinforced concrete slab anti-deformation, strengthens the bearing capacity of concrete folding plate floor, to satisfy the demand of long span building; And possess good insulation, soundproof effect, be suitable for the efficient industrial rate and produce.
The purpose of patent of the present invention is achieved by the following technical solution:
A kind of shaped steel steel plate of the present invention rib reinforced concrete slab, formed by prefabricated panel and cast-in-situ concrete layer, described prefabricated panel is comprised of steel concrete lower floor, horizontal steel tie, light filling piece and the vertical rib of shaped steel steel plate, the steel concrete lower floor of described prefabricated panel is arranged at intervals with respectively longitudinal prestressing reinforcing bar and shape of a saddle transverse reinforcement, and the transverse ends of described shape of a saddle transverse reinforcement has the closed port that upwards stretches out; The vertical rib of described shaped steel steel plate is two, the inboard vertically setting along the transverse reinforcement two ends, and its underpart perforation respectively port with transverse reinforcement is corresponding, and fixes with transverse reinforcement; On described steel concrete lower floor surface, between the vertical rib of both sides shaped steel steel plate, arrange horizontal steel tie by setting parallel interval, in the interval of horizontal steel tie, the light filling piece is set, consist of prefabricated panel, at the construction field (site), build the cast-in-situ concrete layer and form laminated floor slab in moulding prefabricated backplate surface.
Described shape of a saddle transverse reinforcement, the transverse ends of its two parallel reinforcing bars protrude upward and constitute Π shape closed port.
The vertical rib of described shaped steel steel plate is right angle shaped steel steel plate, and its vertical plane has perforation.
The perforation of described right angle shaped steel steel plate is provided with the reinforcing bar draw-in groove, with corresponding horizontal shape of a saddle reinforcing bar fixing.
The horizontal panel of the vertical rib of described horizontal steel tie two ends and right angle, both sides shaped steel steel plate is fixed.
The present invention is provided with horizontal shape of a saddle reinforcing bar in prefabricated panel steel concrete lower floor, the transverse ends of its two parallel reinforcing bars is the Π shape closed ports that protrude upward, the vertical rib of shaped steel steel plate that arranges in the vertical both sides of prefabricated panel, not only the horizontal shape of a saddle reinforcing bar of the perforation of its vertical plate face and steel concrete lower floor fixes, and the two ends of the horizontal steel tie of its level board face and prefabricated panel link, therefore adopt prefabricated panel of the present invention to implement at the scene when cast-in-place, this cast-in-situ concrete and prefabricated panel are connected to form firmly one superimposed sheet.The design's science, simple and direct has little, the good integrity of deadweight, strong, the applicable large characteristics of horizontal span of resistance to deformation performance, and has the performances such as insulation, sound insulation concurrently.Its prefabricated panel can adopt batch production production, and production efficiency is high, easy construction.
