Description

Technical Field

[0001] This utility model relates to the construction of cable-stayed suspension systems and arch bridge construction, and more specifically to an angle-adaptive steel anchor beam. Background Technology

[0002] Currently, arch bridge construction commonly employs the cable-stayed anchoring method. Due to variations in site conditions and bridge type, different arch bridges require different anchor beam designs, resulting in variations in the angle of the steel strands. Each anchor beam at any location needs to be individually designed and fabricated. The large number of steel anchor beams used leads to high costs, and traditional steel anchor beams typically have fixed angles that cannot be adjusted. Furthermore, when the angles of the steel strands differ, reusability is not possible, necessitating the design and fabrication of different steel anchor beams for different angles of steel strands. Utility Model Content

[0003] This patent addresses the aforementioned problems by improving the steel anchor beam and designing an angle-adaptive steel anchor beam that can be applied to different construction scenarios, reused in different bridge projects, thereby improving utilization and reducing costs.

[0004] The technical solution of this utility model is as follows:

[0005] An angle-adaptive steel anchor beam includes: a crossbeam, two sets of supports, and an anchor pad slider;

[0006] The top plate of the crossbeam has notches at both ends for steel strands to pass through;

[0007] The supports are fixed to both ends of the top plate of the crossbeam, and an arc-shaped support panel is fixed on the support; the arc-shaped support panel has a hole in the middle for the steel strand to pass through; and the arc-shaped support panel has baffles on both sides of its edge.

[0008] The anchor block slider consists of a fixed plate, an arc plate, and a connecting part. One end of the connecting part is fixedly installed with the fixed plate, and the other end is connected to the inner wall of the arc plate. The arc plate is placed on the arc support surface, and the outer surface of the arc plate matches the arc support surface. The fixed plate has a circular hole, and one end of the steel strand passes through the circular hole and is clamped by the steel strand clamp.

[0009] The crossbeam includes a bottom plate and a top plate, which are connected by a first connecting plate; multiple sets of first reinforcing plates are welded to the side of the crossbeam.

[0010] The connecting part of the anchor pad slider is composed of multiple second connecting plates and second reinforcing plates.

[0011] The arc-shaped support panel is welded to the top plate of the crossbeam via a third connecting plate, and the support is provided with multiple sets of third reinforcing plates.

[0012] The curved plate is close to the corresponding baffle strips on both sides. That is, the width of the curved plate is slightly smaller than the distance between the two baffle strips.

[0013] All panels are made of Q355B steel plates and are connected by welding.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By using an arc-shaped panel and anchor pad slider, the angle can be adjusted, allowing a single steel anchor beam to be used in different construction scenarios. It can adaptively adjust to various required angles, thereby improving utilization and reducing costs. Attached Figure Description
