Problems solved by technology

[0004] The purpose of the present invention is to: in the prior art, when the main arch is installed with a cantilever assembly method using a cable crane or an arch hoist, the arch line shape of the steel pipe will change with the pouring of the outsourcing concrete, resulting in the buckle cable connector and After the buckle cable is connected, it cannot adapt to the change of the buckle cable angle, resulting in uneven force, and then there are problems affecting the normal installation and use safety of the steel pipe arch bridge. A steel pipe arch bridge buckle cable connecting device and connecting method are provided. The cable connector is hinged on the steel pipe arch, so that when the angle of the cable changes, the cable connector can adapt to the angle change of the cable and rotate accordingly, ensuring that the cable connector is evenly stressed and always in a relatively free state, thereby ensuring Normal installation and quality safety of steel pipe arch bridge

Embodiment 1

[0049] Such as figure 1 with image 3 As shown, the steel pipe arch bridge cable connection device includes a cable connector 1 for connecting with the cable. The steel pipe arch 4 is connected with a hoisting member 2 , and the hoisting member 2 is hinged to the cable connector 1 .

[0050] As one of the implementations, the lifting member 2 includes a fixed part 21, and a hinged part 22 connected to the fixed part 21, the fixed part 21 is connected to the steel pipe arch 4, and the hinged part 22 is connected by the rotating pin 3 Hinged with the buckle connector 1.

[0051] As one of the implementations, the fixed part 21 is a plurality of annular ribs 21a arranged on the outer wall of the steel pipe arch 4, and the plurality of annular ribs 21a are connected side by side to the outer wall of the steel pipe arch 4, and the hinged The part 22 is an ear plate 22a connected to a plurality of annular ribs 21a, and a plurality of annular ribs 21a are arranged on the outer wall...

Embodiment 2

[0064] The buckle cable coupling device of the steel pipe arch bridge of the present embodiment is basically the same as that of Embodiment 1, as figure 2 As shown, the difference lies in the structure of the fixing part 21. In this embodiment, the fixing part 21 is a sleeve 21c set on the outer wall of the steel tube arch 4, and the hinge part 22 is an ear plate 22a connected to the outer wall of the sleeve 21c.

[0065] The fixed part in the form of a sleeve structure is connected to the outer wall of the steel pipe arch, thereby increasing the contact area between the fixed part and the steel pipe arch, and ensuring that the hoisting member has a larger force range and is more uniform and reasonable during the process of hoisting the steel pipe arch.

[0066] Further, the outer wall of the sleeve 21c is connected with sleeve ribs 21d, and the sleeve ribs 21d are respectively arranged at both ends of the sleeve 21c, and the ear plate 22a is connected between the two sleeve r...

Embodiment 3

[0069] Steel pipe arch buckle cable connection method, such as figure 1 with figure 2 Shown, when adopting the fastening cable coupling device of embodiment 1 or embodiment 2 to connect and connect, comprise the following steps:

[0070] a. Connect the hoisting member 2 to the steel pipe arch 4;

[0071] b. Processing buckle connector 1;

[0072] c. Connect and fix the buckle cable on the buckle cable connector 1;

[0073] d. Lift the buckle connector 1 and the buckle to the target installation position, and insert the rotating pin 3 to complete the installation and connection of the buckle connector 1 and the hoisting member 2

[0074] e. Carry out tensioning of the buckle cable and complete the construction of the reorganized buckle cable.

[0075] Step a can also be performed after step c, and it is only necessary to connect the hoisting component to the steel pipe arch before installing the cable connector to the hoisting component.

[0076] In the above way, the hoi...

Abstract

The invention relates to the technical field of bridge construction and in particular relates to a steel pipe arch bridge cable-stay connecting device and connecting method. The steel pipe arch bridgecable-stay connecting device disclosed by the invention comprises a cable-stay connector connected with a cable stay, wherein a hoisting component is connected onto a steel pipe arch and is hinged with the cable-stay connector by virtue of a rotating pin. According to the connecting device, the cable-stay connector is hinged onto the steel pipe arch, so that the cable-stay connector can adapt tothe angle change of the cable-stay so as to rotate when the angle of the cable-stay is changed. Therefore, the uniform stress of the cable-stay connector is ensured, the cable-stay connector is alwayspositioned in a relatively free state, and normal installation and quality safety of the steel pipe arch bridge is further ensured.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a buckle-cable coupling device and a coupling method for a steel pipe arch bridge. Background technique [0002] Steel pipe arch bridges usually use cable cranes or arch hoists to install the main arch in the form of cantilever assembly. When the cantilever method is used for construction, the angle of the buckle cable is fixed, and the magnitude and direction of the force are relatively clear. However, with the application of modern concrete-filled steel tube structure technology characterized by pumped concrete, the removal of buckles can only be carried out after the concrete web of the steel tube arch is poured. The change of the steel pipe arch line will change accordingly, and the angle of the buckle cable will also change accordingly. [0003] Since the thickness of the concrete surrounding the steel pipe arch is relatively thin, only about 600mm at the thinn...
