Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically a type of pre-embedded cable fastener. Background Technology

[0002] In the traditional construction of steel arch frames for arch bridges, the method of fixing the ties using "direct anchorage to anchor piles + simple turning nodes" has obvious drawbacks:

[0003] Force transmission node problem: The cable passes directly through the reserved hole of the anchor pile or is connected through the right-angle turning part without a dedicated tube transition structure. This will cause stress concentration at the corner of the cable due to the sudden change in bending angle, which will accelerate the wear of the cable and increase the risk of breakage.

[0004] Disadvantages of anchorage end structure: Anchorage embedded parts often use single steel sections or simple welded parts, which are insufficient in shear and torsional stiffness and are prone to deformation under diagonal tension loads.

[0005] Existing patents, which employ a single anchoring structure or merely improve the form of the steering component, have not formed a systematic solution of "adjustable tube transition + high-rigidity fixed anchoring".

[0006] Therefore, this utility model provides a pre-embedded shaped fastener to solve the above problems. Utility Model Content

[0008] This utility model provides a shaped pre-embedded fastener, which aims to solve the problems mentioned in the background art.

[0009] (II) Technical Solution

[0011] As a preferred technical solution of this application, the anchoring pre-embedded component includes an anchor, which is fixedly installed in the anchor pile. A steel wire rope is fixedly installed at the left end of the anchor, and a jack is provided at the left end of the steel wire rope. Two sets of steel crossbeams are provided inside the anchor, and a buckle is installed at the left end of the jack. Pre-embedded pipes are inserted into multiple sets of pre-embedded pipes, and the pre-embedded pipes are connected to the jack.

[0012] As a preferred technical solution of this application, the inner wall radius of the multiple sets of pre-embedded pipes is three times or more greater than the diameter of the multiple sets of buckles, and the inner walls of the openings at both ends of the multiple sets of pre-embedded pipes are trumpet-shaped.

[0013] As a preferred technical solution of this application, the jack head is composed of a U-shaped rope clamp and the left end of a steel wire rope.

[0014] As a preferred technical solution of this application, a steel pad is provided at the anchor pile where the jack and wire rope are installed. The upper side of the steel pad is in contact with the wire rope, and the inclination angle of the steel pad matches the direction of the wire rope.

[0015] As a preferred technical solution of this application, the two sets of steel beams are symmetrically fitted together, and the two sets of steel beams are fitted together to form an I-shaped composite section.

[0016] (III) Beneficial Effects

[0017] 1.

[0019] 3. The combined design of multiple sets of pre-embedded pipes and anchoring pre-embedded components forms a complete system of "smooth force transmission - reliable anchoring", which ensures the continuity of load transmission from the arch seat to the anchor pile, avoids the problems of force line disconnection and uneven force distribution in traditional distributed design, and provides stable and reliable support for the construction of the arch seat.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a pre-embedded component for a shaped fastener, such as... Figure 1-4 As shown, the fixed-type cable pre-embedded component includes an arch seat 1 and an anchor pile 2. The arch seat 1 and the anchor pile 2 are arranged in parallel to each other. Multiple sets of front anchor pre-embedded holes 9 are provided on the left side of both the front and rear ends of the arch seat 1, and multiple sets of rear anchor pre-embedded holes 10 are provided on the right side of both the front and rear ends of the arch seat 1. Multiple sets of pre-embedded pipes 11 are fixedly installed in the multiple sets of front anchor pre-embedded holes 9 and multiple sets of rear anchor pre-embedded holes 10. Multiple sets of anchor pre-embedded components are provided in the anchor pile 2.

[0028] During use, the multiple sets of fastening cables 8 first smoothly transition through the multiple sets of pre-embedded pipes 11 in the multiple sets of front anchor pre-embedded holes 9 and multiple sets of rear anchor pre-embedded holes 10, avoiding right-angle bends or small-radius zigzag transitions of the pre-embedded pipes 11 at the turning point of the arch seat 1, thereby effectively reducing the risk of wear and breakage of the pre-embedded pipes 11 due to stress concentration. At the same time, the pre-embedded components are reinforced, thereby improving the shear, bending and torsional stiffness.

[0029] The anchoring pre-embedded component includes an anchor 3, which is fixedly installed inside the anchor pile 2. A steel wire rope 4 is fixedly installed at the left end of the anchor 3, and a jack 5 is provided at the left end of the steel wire rope 4. Two sets of steel crossbeams 6 are provided inside the anchor 3. A fastening cable 8 is installed at the left end of the jack 5. Pre-embedded pipes 11 are inserted into multiple sets of pre-embedded pipes 11, and the pre-embedded pipes 11 are connected to the jack 5.

[0030] Anchor 3, wire rope 4 and jack 5 are fixedly installed in anchor pile 2. The shear, bending and torsional stiffness of the anchor embedded part is enhanced by two sets of steel beams 6 in anchor 3, so that it can reliably bear the diagonal load transmitted by the steel arch frame and suppress out-of-plane displacement and local instability of the anchor end.

[0031] The inner wall radius of the multiple sets of pre-embedded pipes 11 is three times or more greater than the diameter of the multiple sets of buckles 8, and the inner walls of the openings at both ends of the multiple sets of pre-embedded pipes 11 are trumpet-shaped.

[0032] It effectively avoids stress concentration caused by right-angle or small-radius bends, and can significantly reduce the frictional resistance when threading the cable, thus greatly improving the threading efficiency.

[0033] The jack 5 consists of a U-shaped rope clamp and the left end of the steel wire rope 4.

[0034] By using a U-shaped rope clip to engage with the left end of the wire rope 4, the buckle 8 can be quickly and effectively secured, improving construction efficiency.

[0035] The jack 5 and the wire rope 4 are installed at the anchor pile 2 and a steel pad 7 is provided. The upper side of the steel pad 7 is in contact with the wire rope 4, and the tilt angle of the steel pad 7 matches the direction of the wire rope 4.

[0036] The angle of the steel pad 7 is matched with the direction of the steel wire rope 4 to form a smooth force transmission path and eliminate stress concentration at the right angle turn.

[0037] The two sets of steel beams 6 are symmetrically fitted together, and the two sets of steel beams 6 are fitted together to form an I-shaped composite section.

[0038] Compared to single-channel steel, the shear bearing capacity and lateral stiffness are significantly enhanced, effectively suppressing out-of-plane displacement at the anchoring end; the six grooves of the steel beam form a mechanical interlock with the concrete, improving the bonding strength and preventing the embedded parts from being pulled out.

[0039] Working principle: During use, multiple sets of pre-embedded pipes 11 are installed simultaneously with the concrete pouring of the arch seat 1. Then, multiple sets of tie cables 8 are inserted through multiple sets of front anchor pre-embedded holes 9 and multiple sets of rear anchor pre-embedded holes 10. The multiple sets of tie cables 8 are smoothly transitioned through multiple sets of pre-embedded pipes 11. The design of multiple sets of pre-embedded pipes 11 avoids right-angle bends or small-radius zigzag transitions of tie cables 8 at the arch seat 1, thereby effectively reducing the risk of wear and breakage of tie cables 8 due to stress concentration. At the same time, the anchors 3 and wire ropes 4 in the anchoring pre-embedded components are pre-embedded in the anchor piles 2 through concrete. The multiple sets of tie cables 8 are fixedly connected to multiple sets of jacks 5.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
