Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, in particular to a cable hanging anchor structure. Background Art

[0002] During the construction of an arch bridge, it is usually necessary to use a cable crane to lift the arch ribs of the arch bridge. When the cable crane is lifting, the load-bearing cables of the cable crane need to be anchored on the ground. The load-bearing cables play a decisive role in the stability of the cable crane. In the prior art, the anchoring of the load-bearing cables is mainly carried out by anchoring pre-embedded steel sections in concrete and anchoring them through the bonding force between the concrete and the steel sections. This anchoring method is affected by the quality of concrete and has certain uncertainties. The probability of failure due to pulling out is very high. Utility Model Content

[0003] The utility model aims to provide a cable hanging anchor structure to solve the problems raised by the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable hanging anchor structure, including an anchor beam and an anchor cable, the anchor beam is evenly provided with a plurality of through holes, and a plurality of anchor cables are provided, one end of the anchor cable is anchored in the ground concrete layer, and the other end of the anchor cable is passed through the through hole on the anchor beam, and the pad at the end of the anchor cable is pressed against the top surface of the anchor beam through an anchor.

[0005] Furthermore, a plurality of load-bearing cable fixing grooves are evenly distributed on the anchor beam.

[0006] By providing a load-bearing cable fixing groove, when the load-bearing cable is anchored, the load-bearing cable can be wrapped around the anchoring beam in the fixing groove to prevent the load-bearing cable from sliding along the anchoring beam, thereby improving the stability of the load-bearing cable connection.

[0007] Furthermore, concrete is poured inside the anchor beam.

[0008] Pouring concrete into the anchor beam is low-cost and can increase the strength of the anchor beam.

[0009] Furthermore, a support seat is provided below the anchor beam.

[0010] Providing a support seat to support the anchor beam can facilitate the binding and fixing of the load-bearing cable, and the support seat can increase the contact area between the anchor beam and the concrete floor, reducing the damage to the concrete floor when the anchor cable is pre-tensioned.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides an anchor beam and presses the anchor beam against the concrete floor by pre-tightening the anchor cable, so that the tensile capacity of the concrete floor can be tested by arranging a pressure detection device under the anchor beam, and the pre-tightening effect of the anchor cable can provide the anchor beam with a force in the opposite direction to the tensile force of the load-bearing cable before the load-bearing cable of the cable crane is fixed, thereby improving the reliability of the concrete layer or mountain anchor in bearing the tensile force, and the anchor beam is convenient for later disassembly and can be used repeatedly, saving material costs.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a cable hanging anchor structure, including an anchor beam 1 and an anchor cable 2, the anchor beam 1 is evenly provided with a plurality of through holes 12 penetrating up and down, and the side wall of the anchor beam 1 is evenly provided with a plurality of load-bearing cable fixing grooves 14 for fixing the cable hanging load-bearing cables, the interior of the anchor beam 1 is poured with concrete 11, and a plurality of support seats 13 are evenly provided under the anchor beam 1; a plurality of anchor cables 2 are arranged, one end of the anchor cable 2 is anchored in the ground concrete layer 3, and the other end of the anchor cable 2 is passed through the through hole 12 on the anchor beam 1, and the pad 22 at the end of the anchor cable 2 is pressed against the top surface of the anchor beam 1 through the anchor 21.

[0019] In the specific implementation process, when it is necessary to use a cable to lift the arch bridge ribs, firstly, according to the quality of the concrete layer 3 at the construction site and the weight of the arch ribs to be lifted, the appropriate anchor cables 2 are selected and the number of anchor cables 2 is determined. The anchor cables 2 in this embodiment are commercial components that can be purchased on the market. The selection method and anchoring method of the anchor cables 2 are existing methods well known to those skilled in the art and are not described in detail here. After the anchor cables 2 are passed through the through holes 12 of the anchor beams 1 and anchored in the concrete layer 3, the anchor cables 2 can be pre-tensioned by the anchor device 21 to press the anchor beam 1 against the concrete layer 3. In this process, the anchor cables 2 can be pre-tensioned by the anchor device 21. A pressure detection instrument is set under the anchor beam 1 for detection. The numerical value displayed by the pressure detection instrument is compared with the theoretical tension of the load-bearing cable when the cable crane is lifting the arch rib to determine whether the cable crane lifting conditions are met. After the test is completed, the load-bearing cable can be fixed in the load-bearing cable fixing groove 14 to carry out the cable crane lifting construction. The structure of the load-bearing cable fixing groove 14 and the load-bearing cable fixing method can be adjusted according to the experience of technical personnel in this field. It is only necessary to ensure that the anchoring is firm and the load-bearing cable does not slide on the anchor beam 1. In this embodiment, the load-bearing cable fixing groove 14 adopts an annular groove structure, and the load-bearing cable is wrapped around the notch of the annular groove and tied and fixed.
