Abstract
The utility model relates to an arch bridge suspender structure with a rigid tie bar, comprising a sling, wherein one end of the sling is fixed on an arch rib, another end of the sling is fixed on the tie bar, a steel pipe is sleeved with the sling, steel plates are embedded into the arch rib and the tie bar in advance, the steel pipe is fixedly connected with a steel plate, a squeezing hole is arranged on the steel pipe, an upper guide pipe is arranged in the arch rib, a lower guide pipe is arranged in the tie bar; one end of the lower guide pipe contacting with the steel pipe is higher than the tie bar, the steel pipe is fixedly connected with the steel plate by a suspender sleeve; the outer parts of the upper, lower guide pipes are provided with spiral ribs and the upper, lower guide pipes are reinforced and fixed by an anchor steel rib. The safety margin of the suspender is added by sleeving the strained steel pipe with the flexible sling, the service life of the suspender is prolonged. Because the steel pipe can independently bear the load of the sling segment, the sling exchanging has relative small effect on the adjacent suspender and the sling is conveniently exchanged.
Description
Technical field
The utility model relates to the suspension rod design field of arch bridge, especially relates to a kind of arch bridge suspender structure with rigid tie bar.
Background technology
At present, in the construction of arch bridge and design, the flexible hoist cable of general normal employing is as suspension rod, but its in the application of rigid tie bar arch bridge, suspension rod STRESS VARIATION amplitude is bigger on the one hand, and has caused the life-span of hoist cable often shorter, safety stock is not enough; In the process of suspender replacement hoist cable, the STRESS VARIATION amplitude of contiguous suspension rod is often bigger on the other hand, and structure stress is undesirable, changes difficulty.
Summary of the invention
The utility model technical problem to be solved provides a kind of arch bridge suspender structure with rigid tie bar, and it can reduce suspension rod STRESS VARIATION amplitude, prolongs suspension rod application life, under the prerequisite of not appreciable impact structure stress, makes things convenient for suspender replacement.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of arch bridge suspender structure with rigid tie bar, comprise hoist cable, and hoist cable one end is fixed on the arch rib; The other end is fixed on the tie-rod, is with steel pipe on the described hoist cable, is embedded with steel plate in arch rib and the tie-rod; Steel pipe is fixedly connected with steel plate; Steel pipe is provided with the mud jacking hole, is provided with upper conduit in the arch rib, is provided with downcomer in the tie-rod.
Infiltrate entering downcomer in back in the suspension rod for prevention of water at the interface of steel pipe and tie-rod, the end that described downcomer contacts with steel pipe exceeds tie-rod, and steel pipe is fixedly connected with steel plate through the suspension rod sleeve pipe; Further: described downcomer exceeds 5 centimetres of tie-rods.
For adapting to mud jacking technology, for preventing that infiltration from lost efficacy foamed plastics, be provided with steam vent in the arch rib of described upper conduit upper end simultaneously, be provided with drain hole in the tie-rod of downcomer lower end.
In order to strengthen the bonding strength of arch rib and steel pipe, steel plate and steel pipe junction are fixed with stiffener in the described arch rib.
In order to carry the local pressure in arch rib and the tie-rod, described upper conduit and downcomer outside are provided with spiral bar.
In order to be that upper conduit closely is connected with tie-rod with arch rib with downcomer, described upper conduit and downcomer are provided with welding and paste the angle.
The beneficial effect of the utility model is: through increase the safety stock of suspension rod at the stressed steel pipe of flexible hoist cable overcoat, prolong suspension rod application life; Because steel pipe can independently bear the load of its hoist cable section, thus less to contiguous suspension rod influence when changing hoist cable, change conveniently.
