Abstract
The utility model discloses a hollow prestressed reinforced concrete ribbed plate which comprises a prestressed reinforced concrete base plate 1 and reinforced concrete longitudinal ribs 2. Hollow concrete thin-walled boxes 3 are embedded between the base plate 1 and the longitudinal ribs 2 at equal intervals; a wing flange 4 is respectively retained at two sides of the base plate 1; and rib grooves 5 are retained in the transverse direction of the base plate 1. Thus, after a plurality of the hollow prestressed reinforced concrete ribbed plates are assembled, a bottom mold for a reinforced concrete two-way ribbed cover plate in a reinforced concrete cover plate culvert is automatically formed, and then a hollow reinforced concrete two-way ribbed cover plate in the reinforced concrete cover plate culvert is formed by casting reinforced concrete two-way rib beams and panels. The cover plate has the characteristics of large bearing capacity, good integrity, simplicity, convenience and fastness in construction, low construction cost and the like and can be widely used as reinforced concrete cover plates of various culverts in highway engineering.
Description
Technical field:
The utility model relates to the prestressed reinforced concrete hollowcore slab with ribbing of steel bar concrete slab culvert in a kind of highway engineering.
Background technology:
In the design of the cover plate of the steel concrete slab culvert in highway engineering since the span of culvert cover plate generally less (≤6m),, often adopt the prefabricated reinforced concrete solid slab for easy construction, thickness of slab does not wait at 30～50cm.Because banketing on the culvert cover plate is thicker, from great, therefore, its cover plate is as pressing the solid slab design of prefabricated reinforced concrete, and the consumption of its concrete and reinforcing bar is big and uneconomic, and there are not lateral ties between the precast plate, globality is poor, and cover plate itself does not have water proofing property, need carry out construction of waterproof layer, so the overall cost of prefabricated reinforced concrete cover plate is not low.
The steel bar concrete two-way multi-ribbed plate is because two-way with ribbing, and rib spacing is less, and therefore, not only stress performance is good, and rigidity is big, good integrity, be out of shape little, and from heavy and light, material saving, good economy performance.Its inconvenience is that template supports complexity, the cost height, and therefore, the template that if can reasonably handle the steel bar concrete two-way multi-ribbed plate well supports, and its application in the steel bar concrete slab culvert will extensively be promoted.
The utility model content:
The purpose of this utility model is to provide the permanent form of a kind of prefabricated reinforced concrete hollowcore slab with ribbing as close rib building roof, then by after water steel bar concrete girt strip and panel, make it to form the cover plate in the all-in-one-piece steel bar concrete slab culvert.
The technical solution adopted in the utility model is: prestressed reinforced concrete hollowcore slab with ribbing, it comprises a prestressed reinforced concrete base plate, two vertical ribs of steel bar concrete, concrete thin-walled hollow box is embedded between base plate and the vertical rib equally spacedly, and the edge of a wing is left in described base plate both sides, laterally leaves the rib groove.
In order to improve crack resistance, strengthen rigidity and supporting capacity, described base plate adopts prestressed reinforced concrete, and vertical rib adopts steel bar concrete.
Hollow box is the hollow box of concrete opening thin.
Because base plate of the present utility model leaves the edge of a wing, laterally leave the rib groove, after some the utility model assembly units, will form the bed die of the steel bar concrete two-way ribs cover plate in the steel bar concrete slab culvert automatically, build two-way girt strip of steel concrete and panel then, form the hollow cover plate of steel bar concrete two-way ribs.This kind cover plate, it is big to have a bearing capacity, and good integrity, characteristics such as easy construction is quick, cost is low can be widely used in the steel bar concrete cover plate of the various culverts in the highway engineering.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model cross-section cutaway view.
Fig. 3 is the utility model side sectional view.
The specific embodiment:
As can be seen from Figure 1, the utlity model has base plate 1 and vertical rib 2, hollow box 3 is embedded between base plate 1 and the vertical rib 2 equally spacedly, and the edge of a wing 4 is left in described base plate 1 both sides, laterally leaves rib groove 5.Vertical rib 2 adopts steel bar concrete, and base plate 1 can adopt steel bar concrete, but preferably adopts prestressed reinforced concrete, can make its mechanical property better like this, and hollow box 3 adopts the hollow box of concrete opening thin.
