Abstract
The utility model discloses a bridge cord laying cat passage and suspension system device. Two cat passages are respectively arranged in the central positions of an upstream horizontal cord and a downstream horizontal cord, and each cat passage consists of a walkway, an anchoring system and a trimmer joist. The walkway consists of six walkway cords that are positioned with an irregular interval, and is provided with steel plate walkway mesh pieces and antiskid wooden strips on the surface. The steel plate walkway mesh pieces and antiskid wooden strips are bound with iron wires. A bracket is arranged on the walkway every five meters, and each bracket has a roller wheel. Each bracket is connected with the walkway cords via U-shaped clips, and the walkway cords are anchored on the transverse dummy plates on the reserved section of the bridge surface. The track cords and handrail cords are anchored on the bottom plate of the arch rib of the midspan. The anchoring system is provided with pin rolls in the double-piece lifting ears, and connected with a 20-ton assembly pulley having a 5-ton hand-operated adjusting hoist. Six supporting trimmer joists are evenly arranged below the arch rib of the midspan, and each trimmer joist is suspended on the arch rib via steel cables. A platform is provided below each end of a trimmer joist, and the walkway cords are fixed at the bottom of the platform via press plates. The utility model can be used as the auxiliary passage system device for the laying construction of ultra-heavy ultra-long vertical cords across the river before the bridge surface is built in place.
Description
Technical field
The utility model relates to a kind of bridge rope-placing cat walk and suspension system apparatus, and particularly the horizontal rope of ultralong overweight is crossed over the accessory channel system and device that uses in the river surface erection construction before bridge floor is not in place.
Background technology
In the world, the horizontal rope of large span arch bridge erection ultralong overweight is striden in the process of river, and general the employing on the arch put the rope method, and the water surface crosses that Suo Fa is put in the river and auxiliary cableway is installed the rope method of putting.Reach 550 meters Lu Pu bridge for the main span degree, used horizontal rope is in weight, length, diameter and stretching force are unprecedented in rope of the same type, if adopt on the arch and put the rope method, the arch rib that utilization installs is made passage, the subject matter that exists is that the span centre arch rib exceeds about 60 meters than bridge floor, and the width that tilts to the inside diminishes gradually and since the interim knotted rope of arch rib do not remove as yet, horizontal Suo Wufa is transferred to the bridge floor position from arch rib, therefore, workload and the required tractive force of arranging horizontal rope traction and pulley system on the arch rib end face are all very big, and existing equipment can't meet the demands; Cross the river from the water surface and set up, need a large amount of operation at sea, influence the navigation channel, and long construction period, can't satisfy construction period, horizontal rope of while sets up quality also to be difficult to guarantee; Adopt auxiliary cableway to install, the sag of horizontal rope is difficult to control, and construction risk is big, and the tension force of trailer system is very big, and existing equipment can't meet the demands.
Summary of the invention
The purpose of this utility model provides the construction equipment of a kind of auxiliary cat road and the combination of joist suspension, solves the horizontal rope of ultralong overweight and strides the difficult problem that set up in the river, guarantees that the horizontal Suo Shunli of Lu Pu bridge crosses the river and sets up.
For realizing the purpose of this utility model, the technical scheme that is adopted is: a kind of bridge rope-placing cat walk and suspension system apparatus, set up two cat roads respectively in the horizontal rope of upstream and downstream center, per pass cat road is by the aisle, anchor system and joist are partly formed, the aisle is by six roots of sensation aisle rope equidistant placement not, laying steel plate aisle net sheet above is connected with anti-skidding batten and by the iron wire colligation, the support that in the system of aisle, has roller together every five meters settings, support is connected by U type folder with the aisle rope, be provided with the track rope above the support, two limits, aisle are provided with manrope, the aisle rope is anchored in bridge floor and reserves on the diaphragm of section, during being anchored in, track rope and manrope stride on the arch rib base plate, anchor system is established bearing pin in the biplate hanger, and be connected with five tons and pull 20 tons of assembly pulleys regulating cucurbit, in stride supportings joist in six roads evenly be set under the arch rib, the per pass joist is suspended on the arch rib by wire rope, joist two ends below is provided with platform, the aisle rope is fixed on the platform bottom by pressing plate, and the track rope is through the roller at joist top.Mao Dao two ends tension force is in 20 tons, and the span centre maximum defluxion is within two and half.Aisle rope diameter is 32 millimeters a independent wire strand, and track rope diameter is 28 millimeters a independent wire strand.The joist diameter is 900 millimeters, and wall thickness is 20 millimeters, and length is 39 meters steel pipe, and the wirerope diameter that hangs joist is 65 millimeters.
The utility model is owing to adopted technique scheme, therefore setting up the horizontal rope of ultralong overweight, particularly striding the beneficial effect that is had in the erection construction of river at the horizontal rope of Lu Pu bridge is to utilize auxiliary cat road system can solve the horizontal rope of ultralong overweight to stride the difficult problem that set up in the river; Simultaneously, cat road and joist system organically combine, and suspend line style control problem in the air in midair before having solved horizontal rope bridge floor not being in place under stress state, and short construction period, to the minimum that influences in navigation channel.
