Abstract
The utility model provides a novel precast approach bridge which comprises a bridge panel and supporting plates for supporting the bridge panel, and is characterized in that the bridge panel is of an integral structure combined by at least two parts; a group of parallel supporting plates are arranged below each bridge panel; and the opposite surfaces of the supporting plate at the butt joint of two bridge panels are parallel to each other and are planes. By adopting a split reinforced concrete structure, the approach bridge is precast in a factory, and the conventional total road surface is not required to be destroyed during installation, so that the construction time of an urban overpass is shortened; and moreover, by adopting the split precast and combined bearing mode, the precast approach bridge has high bearing capacity and has less possibility of corroded, and the service life of the approach bridge is prolonged.
Description
Technical field
The invention belongs to the bridge construction field, especially a kind of novel prefabricated access bridge structure, it can assemble, shorten the time of the building method of urban interchange fast on the basis of not removing original road surface.
Background technology
The traffic congestion phenomenon of modern society big and medium-sized cities is serious day by day, how to realize the urgent problem that solves of the unimpeded human needs of being of urban traffic.The main cause of city traffic congestion is that road junction, city contact is seized by the throat; Because traffic lights are set lets pass by turns; The vehicle that causes all to pass through slatterns the time more than at least 70%, and just compelled to take the road time nearly more than 70% more for vehicle, thereby the formation traffic is often stopped up.Address this problem and can make the at grade intersection of existing road change graded crossing into, promptly build the urban traffic overpass bridge through improving the crossing, let each Hang Qilu of vehicle, do not disturb mutually.
But modern city builds up already, must shut off traffic in the building course of overpass bridge, and the urban traffic of blocking up is made the matter worse.Even prefabricate mode that is employed in bridge modules such as the column of overground part, bent cap, bent cap bearing and bridge panel can reduce the time that part shuts off traffic, but the access bridge part still needs cast on-site.Therefore, need at first original road surface to be abolished, formwork cast then needs also after the cast that maintenance is more than 28 days at least, and the time that shuts off traffic like this is oversize, and the pressure that urban traffic is caused is too big.If adopt the access bridge of steel work, though shorten the time that shuts off traffic, the abutment of steel work access bridge is embedded in underground for a long time, is very easily penetrated into underground inorganic base or acid corrosion, shortens the application life of access bridge.
Summary of the invention
The technical problem that the utility model will solve provides a kind of prefabricated novel access bridge; It adopts split type reinforced concrete structure, and is at first prefabricated in factory, need not abolish whole existing road surfaces during installation; Not only shortened building the time of urban interchange; And adopting mode separate prefabricated, the combination load-bearing, its weight capacity is strong, be difficult for being corroded, and prolonged the application life of access bridge.
For solving the problems of the technologies described above; The technical scheme that the present invention takes is: a kind of prefabricated novel access bridge; Comprise bridge deck and the gripper shoe that supports said bridge deck; Crucial improvement is that said bridge deck are combined into overall structure by two parts at least, and every part bridge deck below is provided with one group of parallel gripper shoe, and the opposite face of the gripper shoe of two bridge deck joints is parallel to each other and is the plane.
The joint of adjacent two bridge deck and gripper shoe is cast with concrete.
The joint of adjacent two bridge deck and gripper shoe is provided with the reinforcing bar dowel that stretches out.
The construction sequence of above-mentioned access bridge:
A, according to access bridge footing width and size and center, the dark 5cm-10cm groove of milling on original road surface, the levelling of making cement concrete;
B, prefabricated access bridge is installed in the groove successively, the groove that is covered with cement concrete is aimed at the access bridge base angle, makes it firm;
C, with junction, original road surface, according to access bridge headrest size, the open channels on original road surface, the degree of depth surpasses height of headrest 10cm, in ditch, fills out 10cm solid cement concrete, and access bridge ground connection piece is installed;
D, install after, build access bridge with the concrete unification and connect seam, re-lay bridge floor.
The bottom of said gripper shoe is fixed in the groove on the road surface by concrete.Through the structure of concrete, prevent the relative ground motion of access bridge with access bridge and an integral body of ground formation.
The beneficial effect that adopts technique scheme to produce is:
1) the utility model will adopt the access bridge of precast reinforced mixed earth, save the curing time of cast-in-site access bridge, thereby accelerate the speed of building of urban interchange, make city intersection of completion in 7 days become possibility; And the steel concrete access bridge is corrosion-resistant, cost is low;
2) every section access bridge all adopts the branch body structure, is convenient to transportation and prefabricated; The joint of two bridge deck and gripper shoe has rebar connector, is cast with concrete, with two bridge deck of butt joint and the structure of an integral body of gripper shoe formation, has increased safety reliability;
3) groove forms an overall structure to the gripper shoe of access bridge with being provided with on the ground through concrete, has increased the stable degree of access bridge, effectively prevents moving of access bridge.

Wherein, 1-1, left side plate, 1-2, intermediate plate, 1-3, right side plate, 2, gripper shoe, 3, groove, 4, concrete.
The specific embodiment
Fig. 1 is the sectional structure sketch map of the utility model cross section, and it comprises bridge deck and the gripper shoe 2 that supports said bridge deck, and in the present embodiment, said bridge deck are formed overall structure by intermediate plate 1-2, left side plate 1-1 and right side plate 1-3; The below of said intermediate plate 1-2, left side plate 1-1 and right side plate 1-3 is equipped with one group of parallel gripper shoe of one cast; The opposite face of the gripper shoe of the joint of on the left side plate 1-1 and intermediate plate 1-2 and intermediate plate 1-2 and right side plate 1-3 is parallel to each other and is the plane; The gripper shoe bottom footing that connects is half shape of a hoof; The footing that is two gripper shoe bottoms of intermediate plate 1-2 all is half shape of a hoof; The side gripper shoe bottom footing of said left side plate 1-1 and right side plate 1-3 is the shape of a hoof, and opposite side gripper shoe bottom is half shape of a hoof; Referring to Fig. 1.The joint of bridge deck that connect and gripper shoe 2 is provided with the reinforcing bar dowel that stretches out, and in the gap of reinforcing bar dowel, is cast with concrete 4, and bridge deck that connect like this and the gripper shoe that connects are integrally formed structure.
The utility model can also be designed to by two or four access bridges that connect with top according to the width and the carrying situation of bridge floor.
The work progress of the utility model: A, according to access bridge gripper shoe footing width and size and center, the dark 5cm-10cm groove 3 of milling on original road surface, the levelling of making cement concrete;
B, prefabricated access bridge is installed in the groove 3 successively, access bridge gripper shoe footing is aimed at the groove 3 that is covered with cement concrete, makes it firm;
C, with junction, original road surface, according to access bridge headrest size, the open channels on original road surface, the degree of depth surpasses height of headrest 10cm, in ditch, fills out 10cm solid cement concrete, and the ground connection piece is installed;
D, install after, build access bridge with the concrete unification and connect seam, re-lay bridge floor.
To sum up, employing the utility model is simple in structure, cost is lower, be convenient to transportation, supporting capacity is strong, and has shortened building the time of urban interchange.
