Adopt the utility model discloses the construction can be set up the support at the river side and assemble into whole with the arch rib, then with the whole smooth bridge that moves of arch rib, has solved and has set up the problem that the support construction influences the navigation in the river.
Description
Technical Field
The utility model relates to a steel construction arched bridge construction technical field, concretely relates to system of sliding that is used for chevron shape fish belly formula arched bridge to encircle rib installation.
Background
The fish belly formula arched bridge adopts in city river-crossing bridge design as the view bridge usually, during the construction, the installation of arch rib generally adopts the method of setting up the support in the river course to divide the segmental installation, because arch rib section weight is big, the support needs full berth can satisfy the arch rib installation, it corresponds with the breast support to need girder roof upper bracket simultaneously, so that transmit the load to on the basis, the quality is difficult to control in aquatic support setting up, the cost is higher, and under the condition that the river course has the navigation requirement, it can influence the navigation to set up the support.
Disclosure of Invention
The utility model discloses a to above-mentioned problem on the purpose, provide a chevron shape fish belly formula arched bridge arch rib system of wholly sliding, avoid setting up the influence of support to river course navigation, reduce construction cost simultaneously.
The technical scheme of the utility model as follows:
the utility model provides a whole system that slides of chevron shape fish belly formula arched bridge arch rib which characterized in that: the front end bottom of the arch rib and the rear end bottom of the two wings of the arch rib are respectively provided with a group of rollers, each group of rollers is supported on a guide rail, each guide rail is laid along the longitudinal direction of the bridge, the tops of the two bearing platforms of the arch bridge are respectively provided with a counter-force seat, a pull rod is respectively arranged between the two counter-force seats and the rear ends of the two wings of the arch rib in a penetrating way, the rear end of the pull rod is anchored with the arch rib, the front end of the pull rod penetrates through the counter-force seats and a traction jack, and the base of the traction jack is supported on the front end surface of the counter-force seat; a temporary tie bar is respectively arranged between the front end of the arch rib and the rear ends of the two wings of the arch rib in a penetrating way.
The utility model discloses during the construction, can set up the support earlier and assemble into wholly with the arch rib in the river side, then with the whole smooth bridge that shifts of arch rib, the arch rib is assembled the support and is all set up basically on the land, does not influence the navigation, has solved and has set up the problem that the support construction brought in the river. The erection of the land support is easy to control, the construction is convenient, the overwater workload is less, and the construction cost can be reduced.

Detailed Description
As shown in fig. 1 and 2, a group of rollers 2 are respectively arranged at the bottom of the front end of a herringbone fish belly type arch rib 1 and the bottom of the rear ends of two wings of the arch rib, each group of rollers is supported on a guide rail 3, each guide rail 3 is laid along the longitudinal direction of the bridge, reaction seats 5 are respectively arranged at the tops of two bearing platforms 4 of the arch bridge, pull rods 6 are respectively arranged between the two reaction seats 5 and the rear ends of the two wings of the arch rib in a penetrating manner, the rear ends of the pull rods are anchored with the arch rib, the front ends of the pull rods 6 penetrate through the reaction seats 5 and penetrate through traction jacks 7, and bases of the traction jacks 7 are supported on the front end surfaces of the reaction seats 5; a temporary tie bar 8 is respectively arranged between the front end of the arch rib and the rear ends of the two wings of the arch rib.
As shown in fig. 3, the axle 9 of the roller 2 transversely passes through the lower end of the arch rib 1, and two ends of the axle are respectively provided with a roller; limiting plates 10 protruding upwards are respectively arranged on two sides of the guide rail 3 to prevent the roller from derailing when sliding
As shown in fig. 4, the top surface of the bearing platform 4 is provided with an embedded steel plate 11, and the bottom of the reaction force seat 5 is welded on the embedded steel plate.
Adopt the utility model discloses install the arch rib on the arch bridge, need assemble into whole with the arch rib at the bridgehead. When the arch bridge bearing platform is poured, arranging an embedded steel plate at the top, and welding a counter-force seat on the embedded steel plate; 3 guide rails are laid at the bridge head along the bridge direction, then a support is erected at the bridge head of the arch bridge to assemble arch ribs, and during assembly, rollers are mounted at the front ends of the arch ribs and the bottoms of the rear end sections of the two wings in advance and are supported on the guide rails. After the arch rib is assembled, a temporary tie bar is arranged between the front end and the two rear ends of the arch rib, a pull rod penetrates through the counter-force seat and the rear ends of the two wings of the arch rib, a traction jack is arranged at the front end of the pull rod, the arch rib is pulled to slide forwards for one section every time the jack pushes one stroke, and pushing is repeated until the arch rib is completely slid to the installation position.
