Abstract
The utility model discloses a hollow slab bridge girder construction, include the violently hollow sheet layer of the mutual concatenation of the level of indulging of a plurality of cored slabs to and lay in the supercrust on hollow sheet layer upper portion, form the hinge seam between the horizontal cored slab, its characterized in that: the bottom and the upper portion symmetry of cored slab are equipped with the prestressing steel pipeline, and these pipeline both ends still are connected with the anchor slab, prestressing steel on the cored slab anchor slab respectively with two upper and lower anchor slabs of adjacent cored slab on prestressing steel articulated. The utility model discloses a lower part sets up prestressing steel pipeline and anchor slab on hollow core slab, and is articulated each other through prestressing steel between the cored slab adjacent like this, has strengthened the connection rigidity between the cored slab.
Description
Technical field
The utility model relates to a kind of hinged hollow slab bridge girder construction, belongs to bridge field.
Background technology
Assembling Hollow Slab Beam Bridge have form of structure simple, by material economy, prefabricated convenience, be easy to standardized production and construction, be convenient to the advantages such as transporting and hoisting, apply comparatively general.But this kind of bridge type Calculation of Thickness of Bridge Deck Pavement is less is generally 8cm, and direction across bridge rebar spacing is generally 15cm more greatly.Bridge deck pavement thickness is inadequate, and bar diameter is less, spacing arranges that the tensile property that the situation such as larger makes to mat formation is poor, and the synergy of beam body reduces, integral rigidity reduces.The concrete hinge seam watered after lateral ties in addition between each plate-girder of hollow slab bridge mainly rely on realizes, its objective is and the Local Loads transverse distribution acted on lane plate is born jointly to each plate-girder, realize the collaborative work of many plates, avoid the disadvantageous single slab bearing phenomenon of structure.But due to the impact of design, reason in construction and operating environment, it is the FAQs of threat hollow slab bridge operation security all the time that hinge seam destroys.
Utility model content
The utility model causes by concrete hinge seam singular association the shortcoming that beam bridge integral rigidity is lower between current hollowcore slab, provides a kind of hollowcore slab anchoring interconnective hollow slab bridge girder construction.
The technical scheme in the invention for solving the technical problem is:
Hollow slab bridge girder construction, comprise the hollow flaggy that some hollowcore slab transverse and longitudinal levels are spliced mutually, and be layed in the supercrust on hollow flaggy top, hinge seam is formed between horizontal hollowcore slab, it is characterized in that: the bottom of described hollowcore slab and top are arranged with prestressed reinforcement pipeline, this pipe ends is also connected with anchor slab; Prestressed reinforcement on hollowcore slab anchor slab is hinged with the prestressed reinforcement on two anchor slabs up and down of adjacent vacant core respectively.
The bottom of described hollowcore slab and both upper ends thereof all form outward extending cantilever, and described prestressed reinforcement pipeline runs through the cantilever at the upper and lower two ends of hollowcore slab; The anchor slab in same level face is hinged, and forms the bottom surface of cutting with scissors and stitching with extension cantilever.
Two symmetrical kidney ellipsoid holes are provided with in described hollowcore slab.
Described supercrust by transverse reinforcement and longitudinal reinforcement form main body layer of concrete.
The thickness of described layer of concrete is 10 ~ 15cm.
Described layer of concrete concrete used is the waterproof concrete that label is greater than C40.
Described prestressed reinforcement scribbles corrosion-resistant coating.
Described prestressed reinforcement pipeline is pvc pipe.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by arranging prestressed reinforcement pipeline and anchor slab in precast hollow slab top and the bottom, is hinged by prestressed reinforcement between such adjacent vacant core, enhances the coupling stiffness between hollowcore slab.
In addition, the bottom of hollowcore slab and both upper ends thereof all form outward extending cantilever, and described prestressed reinforcement pipeline runs through the cantilever at the upper and lower two ends of hollowcore slab; The anchor slab in same level face is hinged, and form the bottom surface of cutting with scissors and stitching with extension cantilever, then the hinge formed at prestressed reinforcement and cantilever stitches filling concrete between bottom surface, and the hinge made like this seam is for " Shen " font, and this structure hinge sewer has and bears more by force shearing, axle power.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1: hollow slab bridge girder construction, comprise the hollow flaggy 10 that some hollowcore slab 12 transverse and longitudinal levels are spliced mutually, and be layed in the supercrust 20 on hollow flaggy top, hinge seam 11 is formed between horizontal hollowcore slab, horizontally set two hollowcore slabs in the present embodiment diagram, reality can need to increase horizontal hollowcore slab quantity according to road surface.The bottom of hollowcore slab and both upper ends thereof all form outward extending cantilever 121, and the bottom of hollowcore slab and top are arranged with prestressed reinforcement pipeline 122, and this prestressed reinforcement pipeline runs through the cantilever at the upper and lower two ends of hollowcore slab, and pipe ends is also connected with anchor slab 123; Prestressed reinforcement on hollowcore slab anchor slab is hinged with the prestressed reinforcement on two anchor slabs up and down of adjacent vacant core respectively.Like this, the anchor slab in same level face is hinged, and forms the bottom surface of cutting with scissors and stitching with extension cantilever, and the hinge then formed at prestressed reinforcement and cantilever stitches filling concrete between bottom surface, the hinge seam made like this is for " Shen " font, and this structure hinge sewer has and bears more by force shearing, axle power.
In addition, for reducing hollowcore slab weight, two symmetrical kidney ellipsoid holes 124 in hollowcore slab, are provided with.For ensureing the structural strength of prestressed reinforcement, prestressed reinforcement scribbles corrosion-resistant coating, and prestressed reinforcement pipeline is pvc pipe.
In addition, supercrust by transverse reinforcement and longitudinal reinforcement form main body layer of concrete.The thickness of preferred layer of concrete is 10 ~ 15cm.Concrete adopts label to be greater than the waterproof concrete of C40.
