Description
Technical field
The utility model belongs to technical field of bridge construction, and in particular to a kind of anchoring of multispan arcading bridge section tie-rod rope
Structure.
Background technique
Arch bridge can generate horizontal thrust under the action of vertical load, need to offset this level using horizontal rope and push away
Power can just make infrastructure bear lesser horizontal force, it is ensured that basic stress is safe and reliable in this way.
General arch bridge pontic is equipped with stringer, and stringer refers to being in same plane with arch rib in superstructure, along bridge
Beam longitudinally disposed and that bridge deck is collectively formed with crossbeam, floorings.Stringer case refers to stringer top plate and bottom plate and left and right web
Cabinet made of (plate of side) encloses, as shown in Figure 3.
For single span arch bridge, generally horizontal rope is arranged in the case of stringer, on the one hand can improve the use environment of rope, separately
Traditional steel anchor box can be used in one side rope anchoring structure.And it is arranged so the requirement for being generally also able to satisfy horizontal cable stretching, because
It is generally dividing strip for the bridge floor region where arch rib, can not arrange girder in access bridge side.
But for Multi-arch bridge, in order to offset horizontal thrust of the intermediate arches across generation, generally require corresponding across interior cloth
Set segment tie-rod rope, at this moment, if will tie-rod rope be arranged in steel case stringer, on the one hand, due to having been arranged in stringer case
Elongated rope (elongated rope is the long rope drawn from whole bridge one end to the other end that Multi-arch bridge was equipped with originally), increases arrangement segment rope meeting
Keep space in case crowded；On the other hand, in the case, tension operation is also very inconvenient for segment rope arrangement.This is because steel case stringer
It is continuously that the disengaging of straining device needs in addition to punch, narrow space in case, mobile, tension operation inconvenience.And segment rope
Tensioning after main structure is built up and using the maintenance stage it is still in need, and at this moment in order to horizontal cable stretching utensil disengaging need
It to punch to existing structure, structure is had damage.The operations such as the tensioning to segment rope may touch, damage elongated rope.
Summary of the invention

On the outside of plate, it is fixedly connected；
It is (opposite with 5 extending direction of tie-rod rope i.e. towards arch outside direction that the end plate 1 is set to biography outer one end of shear 2
One end), it is fixedly connected both perpendicular to biography shear 2 and stringer case side plate, 1 simultaneous interpretation shear 2 of end plate；The end plate 1 is equipped with rope
Hole；
The anchor plate 4 is set to 1 lateral funiculus hole site of end plate, corresponding on anchor plate 4 to be equipped with and rope hole is in the same size
Perforation；Anchor plate 4 is fixedly connected with end plate 1；
The stiffener 3 is rectangular slab, if there is dry plate, places and parallel to each other vertically, is respectively perpendicular and is set to biography shear 2
Between, the biography shear 2 adjacent with upper and lower two panels is fixedly connected；Wherein:
Upper and lower two panels passes shear 2 and left and right two panels stiffener 3 forms several cuboid cavitys, wherein having for tie-rod
The cuboid cavity that rope 5 passes through, the cuboid cavity face the rope hole of end plate 1；
5 both ends of tie-rod rope are equipped with anchor head, and one end of tie-rod rope 5 passes through the Suo Konghou of the end plate 1 of an anchor case 8, uses
The locking of one nut 6,6 end face stress of nut are against on anchor plate 4.
In the utility model, on the inside of stringer case side plate (web), the corresponding position for passing shear 2 is additionally provided with several auxiliary
Stiffener 7；It is horizontal positioned and parallel to each other to assist stiffener 7, and is vertically installed in stringer case side plate interior sides, is fixedly connected.It is auxiliary
Helping stiffener 7 is the stabilization for further strengthening stringer case side plate, and balance passes shear 2 and bends effect to the song of stringer case side plate.
In the utility model, described is fixedly connected as welding.
In the utility model, shear is passed with stiffener and forms several cuboid cavitys being connected, additional end plate sealing-in exists
The one end of cuboid cavity forms a firm structure framework, as anchor case；Passing shear is that the anchor force of tie-rod rope is passed
The side plate of stringer is passed, each biography shear is fixed together by stiffener；It interacts, plays further strengthening biography and cut
The stabilization of plate；Anchor case is set on the outside of stringer case side plate, and two anchor casees are respectively arranged at main span arch both sides, 5 both ends of tie-rod rope point
Not with the end plate connection of two anchor casees, the horizontal thrust that the span of arch generates is born.
The utility model structure is simple, external anchor case and tie-rod rope, can meet multispan multiple-arch bridge main span segment tie-rod rope
Arrangement space demand is convenient for construction and maintenance, and when tie-rod rope installs simultaneously tensioning, straining device is limited less by structure space, is convenient for
Installation and removal.
