Description

Technical Field

[0001] This utility model belongs to the field of steel arch rib hoisting technology, specifically relating to a limiting device for positioning steel arch rib hoisting. Background Technology

[0002] Tied-arch bridges, also known as thrustless arch composite system bridges, are a type of bridge that combines the advantages of both arches and beams. They combine the two basic structural forms of arches and beams to jointly bear loads, fully utilizing the structural performance of beams under bending and arches under compression, as well as their combined effect. Depending on the connection method between the arch ribs and the roadway beams, arch composite system bridges can generally be divided into thrust-supported and thrustless types, with tied-arch bridges belonging to the thrustless arch composite system category. The arch ribs of a tied-arch bridge require a support system during construction to provide necessary support and fixation. However, in actual construction, when the arch ribs are hoisted and placed onto the support system, positional deviations can easily occur, hindering precise positioning of the arch ribs and thus affecting actual construction efficiency and quality.

The device features a clever and reasonable structural design with strong practicality. The entire limiting device is installed and fixed on temporary supports via a support base. Sliding support components support and limit the two sides of the steel arch rib, while height support components support and limit the bottom of the steel arch rib. This achieves precise support and positioning of the steel arch rib, ensuring the stability and accuracy of hoisting and positioning, effectively improving construction quality and efficiency. Furthermore, the sliding support components are adjustable, allowing their position to be adjusted according to actual needs, enhancing the device's versatility and flexibility.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The support base is connected to a temporary support. The support beam is welded and fixed to the support base. Two sets of sliding support assemblies are symmetrically arranged at both ends of the support beam and are adjustablely connected to it. The two sets of sliding support assemblies provide limiting support on both sides of the steel arch rib. The height support assembly is located between the two sets of sliding support assemblies and is fixedly mounted on the support beam. The height support assembly provides support contact with the steel arch rib. The bottom of the arch rib features a clever and reasonable structural design with strong practicality. The entire limiting device is installed and fixed on temporary supports through a support base. The sliding support assembly supports and limits the two sides of the steel arch rib, while the height support assembly supports and limits the bottom of the steel arch rib. This achieves precise support and positioning of the steel arch rib, ensuring the stability and accuracy of the hoisting and positioning of the steel arch rib, effectively improving construction quality and efficiency. Furthermore, the sliding support assembly is adjustable, allowing its position to be adjusted according to actual needs, thus improving the versatility and flexibility of the device.

[0006] Furthermore, connecting columns are provided at all four corners of the bottom of the support base. Flange blind plates are welded and fixed to the bottom of the connecting columns. Connection holes are provided on the flange blind plates. The structural design is ingenious and reasonable.

Both ends of the support beam are equipped with side support plates. The other end of the adjusting screw passes through the corresponding side support plate, and the adjusting screw is clamped and fixed to the side support plate by two limiting nuts. The two limiting nuts are located on both sides of the side support plate. This ingenious design ensures the firmness and reliability of the sliding support assembly on the support beam by clamping and fixing the adjusting screw to the corresponding side support plate through the two limiting nuts. Moreover, by adjusting the length of the adjusting screw passing through the side support plate, the position of the limiting bracket can be adjusted, so that the sliding support assembly can be adjusted according to the size of the steel arch rib, the hoisting position requirements, etc., thereby facilitating the precise placement of the steel arch rib in the subsequent hoisting.

[0012] Furthermore, the limiting bracket has a triangular structure, which is ingenious and reasonable in its design. This ensures the structural stability and firmness of the limiting bracket, guarantees its stable support and limiting of the steel arch rib side, and improves its safety and service life.
