Description

Suspension type cat road veil installation system
Technical field
This utility model relates to Architectural Equipment field, especially relates to a kind of suspension type cat road veil installation system.
Background technology
Suspension bridge, has another name called suspension bridge (suspension bridge), refers to be hung and be anchored in the cable (or steel chain) bridge as the main supporting member of superstructure of two sides (or bridge two ends) by Sarasota.Its cable geometry is determined by the equilibrium condition of power, normally close to parabola.Hang down many suspension rods from cable, bridge floor is hung, standing between bridge floor and suspension rod put stiff girder, form combined system with cable, to reduce the deflection deformation caused by mobile load.
Suspension bridge is mainly made up of parts such as suspension cable, Sarasota, anchorage, suspension rod, bridge decks.The main supporting member of suspension bridge is suspension cable, and it is primarily subjected to pulling force, and the steel (steel wire, wirerope etc.) that general tensile strength is high make.Typically being respectively provided with a cables in the both sides of bridge, two ends are fixed on the anchor ingot of bank, bear weight by these two main push-towing ropes, arrange two towering Sarasotas kept at a certain distance away, be used for supporting main push-towing rope on river surface.Commonly referred to as main span between two Sarasotas, the distance of two Sarasotas to bank is commonly referred to as end bay.
Cat road is erected under main push-towing rope when being suspension bridge construction, is parallel to the linear temporary construction sidewalk of main push-towing rope.It is the height scaffolding that workmen carries out construction operation, is main push-towing rope system or even the operation platform of the whole superstructure of suspension bridge.Workmen completes such as strand traction thereon, saddle, tight cable, cord clip and hoist cable are installed, box beam lifts and building site connects, main push-towing rope twines the vital task such as silk, protective coating to adjust stock, shaping to enter.Each one of upstream and downstream, section is the most U-shaped, long and narrow and have some to rock, therefore claims " cat road ", and English is catway.It is extremely important temporary facility in suspension bridge construction, and bridge will be removed after being completed.
Cat road system is typically made up of track cable (including bitter end length adjustment device), surface layer, railing and handrail, interconnection, global anti-wind system etc..
The main bearing member of track cable Shi Weimao road structure, it is common that use the steel wire rope of twisting to make.According to construction requirement and external design and construction experience, the general centrage by cat road shaping rear load-bearing rope is less than main cable erection centrage about 1.5m setting.The selection of this distance, in time should taking into full account main cable erection workmen easy to operate in addition to, it is often more important that use the working place requirement of special machine (such as: cable compacting machine, winding machine and wire) when must take into the traction of strand, the banding of main push-towing rope and application.
Cat road surface layer includes steel web frame, is divided into upper and lower two-layer, and one thick one is thin, becomes cat road veil.The layout of cat road surface layer not only should have the structure structure being easy to safety work, also should consider when selection that meeting cat road entirety has enough rigidity.For the requirement of working space, the design width in cat road usually takes about 4.0m.Design cat road centrage keeps consistent with main push-towing rope centrage vertical simultaneously, so after main push-towing rope molding, loosening a series of operations such as cat road track cable, is suspended to cat road on main push-towing rope be prone to keep balance.
Cat road arranges railing post every several meters, sets a manrope and one to two root guard rope, the handrail that manrope is walked mainly as workman with steel wire rope on the every lateral rail of length range, and guard cable is mainly used in fixing side shield net, to ensure safety.Side shield net uses the big eye steel wire of high about 1.0m.
The interconnection in cat road can meet the cat road contact between upstream and downstream, convenient construction personnel and equipment and the transfer of material, and improves the stability in the large in cat road self, strengthens its wind loading rating, perpendicular with main push-towing rope.For reducing dead load quality, horizontal overline bridge is considered as the truss structure of steel pipe or square steel, and should carry out structural strength checking computations.The surface layer of interconnection and railing protection Ke Yumao road surface layer are arranged identical.
The global anti-wind system in cat road, owing to the construction of main push-towing rope belongs to work high above the ground, and the construction being now arranged in the bridge spanning the sea in high wind area increases, so the impact of wind becomes especially prominent.For wind resisting stability, the enough rigidity in construction period cat road and adjust linear needs, below cat road, generally set wind resistance cable system and horizontal overline bridge passage) ensure.Wind resistance cable can not be set for various reasons, the density of horizontal overline bridge can be increased or use other measures to strengthen stability and the rigidity in cat road.The global stiffness in cat road is relevant with the quality in the span of track cable, the pretension of wind resistance cable and cat road with stability.Though cat road is the temporary structure of work progress, but in use it is also possible to be attacked by high wind and typhoon.In order to ensure cat road use during safety, the wind loading rating in the set cat road of checking, the cat road structure of general suspension bridge also should do wind tunnel test and wind resisting stability analysis and calculating.Additionally on cat road also should arrange illumination and caution device, it should by unit in charge of construction according to use and navigation need lay.
In the prior art, the construction in cat road typically uses artificial laying, and workmen steps down in and lays cat road veil and railing post etc. piecewise on cat road track cable, in work high above the ground, danger very, lays under efficiency, and laying is long for man-hour, lays relatively costly.
Based on this, this utility model provides a kind of suspension type cat road veil installation system to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is to provide a kind of suspension type cat road veil installation system, to solve to lay in prior art cat road surface layer length in man-hour, cost technical problem high, inefficient.
In embodiment of the present utility model, provide a kind of suspension type cat road veil installation system, described suspension type cat road veil installation system include two hoist engines, two pull device, a plurality of cat road track cable and a plurality of interconnection;
