Abstract
The utility model discloses a novel cat road bridge main rope structure, including a wire rope and two anchor logs, two the anchor log sets up respectively at either end of a bridge and bridge tail, and punish at two anchor logs and do not install a fixed pulley, wire rope one end is fixed on the anchor log of either end of a bridge, and the fixed pulley of bridge tail is walked around earlier to the other end, then turns back and walk around the fixed pulley of either end of a bridge, fixes the end on the anchor log of bridge tail at last. The beneficial effects of the utility model are that: the disposable installation of wire rope, the vector of each section of wire rope is unanimous, and the atress is even, and the bridge floor all keeps on a horizontal plane at any state, need greatly not practice thrift the engineering time to one ground regulation of each wire rope like traditional mode, has also saved a large amount of manpower and materials to reduced construction cost, improved wire rope and receive the mechanical mass.
Description
Technical field
The utility model relates to construction engineering technical field, particularly a kind of novel cat bridge main rope structure.
Background technology
Cat bridge belongs to little sag flexible suspension bridge, have the construction period short, invest the advantages such as minimum, lightweight, the material usage province of constructing, particularly suitable Yushan Hill height slope is steep, The water is deep and the current fast, drift is many, river bed quicksand washes away in the terrain environment of the geographical conditions extreme difference such as large.Cat bridge is usually used in the place that main equipment cannot arrive at all and is used as interim bridge or construction bridge, passes through and pump carries out generous amount concrete fast transportation ordinatedly with convenient working personnel, plays its unique applications.
At present when construction cat bridge, substantially be all adopt many wire rope to be connected respectively with the anchoring pile of two sides, this mode not only speed of application is slow, and the vector of every root wire rope is difficult to regulate unanimously, cause the discontinuity of each wire rope, be difficult to keep bridge floor in one plane.
Summary of the invention
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of novel cat bridge main rope structure.
The technical solution adopted in the utility model is such:
A kind of novel cat bridge main rope structure, comprise steel cable and two anchoring piles, two described anchoring piles are separately positioned on end of the bridge and bridge tail, at two anchoring pile places, a fixed pulley is installed respectively, described wire rope one end is fixed on the anchoring pile of end of the bridge, the other end first walks around the fixed pulley of bridge tail, then turns back and walks around the fixed pulley of end of the bridge, is finally fixed on termination on the anchoring pile of bridge tail.
As preferably, the center of two fixed pulleys distance that misplaces in the longitudinal direction of bridge equals fixed pulley diameter, and wire rope is walked around three sections that two fixed pulleys are formed and is parallel to each other.Wire rope walk around three sections that two fixed pulleys are formed not parallel also passable, but the stress of wire rope under carrying condition is just larger.Therefore, in order to improve security system, the diameter of fixed pulley being done a bit make to be parallel to each other between three of wire rope sections greatly as much as possible.
As preferably, described fixed pulley diameter is 70cm, and the center of two fixed pulleys distance that misplaces in the longitudinal direction of bridge is 70cm.
As preferably, each section of wire rope common place plane lays steel mesh reinforcement and colligation is fixed, and then layer overlay bamboo slab rubber is as bridge floor.After spreading steel mesh reinforcement and bamboo slab rubber, then in both sides, guardrail is installed, just can have walked safely above.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
The disposable installation of wire rope, the vector that wire rope is each section is consistent, uniform force, bridge floor all remains on a horizontal plane in any state, do not need to regulate one by one each wire rope as traditional approach, greatly saved the engineering time, also saved a large amount of manpower and materials, thus reduce construction cost, and improve main rope by mechanical mass.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Mark in figure: 1 is anchoring pile, and 2 is fixed pulley, and 3 is wire rope.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.

Described fixed pulley 2 diameter is 70cm, and the center of two fixed pulleys 2 distance that misplaces in the longitudinal direction of bridge is 70cm.
Embodiment 2:
A kind of novel cat bridge main rope structure, comprise steel cable 3 and two anchoring piles 1, two described anchoring piles 1 are separately positioned on end of the bridge and bridge tail, at two anchoring pile 1 places, a fixed pulley 2 is installed respectively, described wire rope 3 one end is fixed on the anchoring pile 1 of end of the bridge, the other end first walks around the fixed pulley 2 of bridge tail, then turns back and walks around the fixed pulley 2 of end of the bridge, be finally fixed on termination on the anchoring pile 1 of bridge tail.
Described fixed pulley 2 diameter is 70cm, and the center of two fixed pulleys 2 distance that misplaces in the longitudinal direction of bridge is 70cm.
Each section of wire rope 3 common place plane lays steel mesh reinforcement and colligation is fixed, and then layer overlay bamboo slab rubber is as bridge floor.
