Abstract
The utility model relates to a hollow slab bridge structure with an integration pavement layer. The hollow slab bridge structure comprises a prefabricated hollow slab and the integration pavement layer, and is characterized in that structural reinforcing steel bars which extend out of the surface to be connected with the integration pavement layer are arranged at the slab top of the prefabricated hollow slab, and a double-layer reinforcing steel bar net is arranged on the integration pavement layer. According to the hollow slab bridge structure, the integration pavement layer has the good durability and the good integrality, transverse distribution of loads can be well achieved, and effective connection between the hollow slab and the integration pavement layer is guaranteed through the structural reinforcing steel bars which extend out of the top of the hollow slab to be connected with the integration pavement layer. Due to the fact that a hinged seam structure is eliminated, the defects that in an assembly type hollow slab bridge hinged-seam junction face structure commonly used domestically at present, reinforcing steel bars are difficult to pick out, the hinged-seam field construction difficulty is high, and diseases are prone to being generated in practical use are overcome.
Description
Technical field

Background technology
According to interrelated data, show, end assembling Hollow Slab Beam Bridges in 2010 shared ratio in highway in China Modular Bridge System and reached 64%.This class bridge have building height low, be convenient to the advantages such as prefabricated, design and construction is easy.Domestic conventional assembling hollow slab bridge is first pulled hollowcore slab and hinge seam bonding surface distributing bar to the position of being close to side form when prefabricated plate-girder at present, after form removal, pulled out, but often easily there is the phenomenon of distributing bar Transducers Embedded in Concrete, cause and pull out difficulty.Hinge seam construction size is relatively little, and reinforcing bar is intensive, and when construction hinge seam structure, concrete is difficult to effectively be vibrated.By the assembling hollow slab bridge to runing, carry out field investigation discovery, because many reason hinges of design, construction and operation stage are stitched the Major Diseases form that the hinge seam diseases such as bottom infiltration is whitened, bottom mortar comes off, longitudinal cracking become this class bridge.Along with the development of hinge seam disease, hinge seam structure is progressively lost the ability of lateral transport load, finally causes the stressed phenomenon of veneer to occur, assembling hollow slab bridge life-span and traffic safety are caused to grave danger.
Summary of the invention
In order thoroughly to avoid hinge seam structure many defects in actual use at present, technical problem to be solved in the utility model is to provide a kind of with the mat formation hollow slab bridge structure of layer of integration, not only improved adopt this with integration reliability and the durability that the hollow slab bridge of layer laterally connects of mating formation.Owing to having cancelled hinge seam structure, avoided that current domestic conventional assembling hollow slab bridge hinge seam bonding surface distributing bar digs out that difficulty, hinge seam site operation difficulty are large, be prone to the shortcoming of disease in practical application.
To achieve these goals, the technical solution of the utility model is: described precast hollow slab has and stretches out surface and the integration distributing bar that is connected of layer of mating formation at Ban Ding, the described integration layer layout double steel bar net of mating formation.
Further, described precast hollow slab transverse shape is the rectangle with circular hole, this hollowcore slab height is conventional same little across hollowcore slab height under footpath with respect to domestic, all the other structures are identical, described to stretch out mat formation distributing bar that layer is connected of Method Pre-stress Concrete Hollow Slab top and integration be the mat formation handling reinforcement of layer steel mesh reinforcement of integration, and bridge is indulged to interlaced arrangement in the stirrup edge in itself and hollowcore slab.
Further, described integration mat formation layer thickness minimum be 20cm, reinforcing bar horizontal spacing is 10cm-15cm.
The mat formation construction method of hollow slab bridge structure of layer of the utility model band integration, carry out according to the following steps: (1), when precast hollow slab, carries out colligation or welding by stretching out Method Pre-stress Concrete Hollow Slab top and the integration main muscle of tension at the bottom of layer distributing bar being connected and plate upper frame stud and plate of mating formation according to design attitude; (2), after stripping, precast hollow slab is lifted on the seating plane of design; (3) according to design attitude colligation integration mat formation layer reinforcing bar; (4) poured integral mat formation layer concrete.
Further, described in step (1) and (2), precast hollow slab transverse shape is the rectangle with circular hole, described precast hollow slab transverse shape is the rectangle with circular hole, and this hollowcore slab height is conventional same little across hollowcore slab height under footpath with respect to domestic, and all the other structures are identical.Described to stretch out mat formation distributing bar that layer is connected of Method Pre-stress Concrete Hollow Slab top and integration be the mat formation handling reinforcement of layer steel mesh reinforcement of integration, and bridge is indulged to interlaced arrangement in the stirrup edge in itself and hollowcore slab.
Further, the integration described in step (3) and (4) mat formation layer thickness minimum be 20cm, reinforcing bar horizontal spacing is 10cm-15cm.
Further, in step (4), the described integration layer concrete of mating formation should be integral cast-in-situ.
As known from the above, the utility model as a kind of with the mat formation construction method of hollow slab bridge structure of layer of integration, not only improved and adopted thisly with integration reliability and the durability that the hollow slab bridge of layer laterally connects of mating formation, and overcome that current domestic conventional assembling hollow slab bridge hinge seam bonding surface distributing bar digs out that difficulty, hinge seam site operation difficulty are large, be prone to the shortcoming of disease in practical application.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
