Abstract
Description
Technical Field
[0001] This utility model relates to a combined tensioning fixture for finished steel strand suspension cables, belonging to the technical field of bridge tensioning equipment. Background Technology
[0002] During the operation of cable-stayed bridges, cable tension deviations may occur, necessitating the use of appropriate tension adjustment devices to regulate the cable tension. This ensures both the safety of bridge operation and allows for scientific management based on tension adjustments. Currently, the anchor cup and tie rod are connected via a connecting sleeve, which occupies a large space and leaves limited tensioning space, failing to meet tension requirements. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a steel strand finished cable combination tensioning fixture that is simple in structure, easy to operate, space-saving, and meets the tension force requirements.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a combined tensioning fixture for finished steel strand suspension cables, including an anchor cup, the bottom of which is located inside an anchor plate, and the anchor plate is located on a bridge body plate; an anchor cup nut is fitted on the anchor cup, the anchor cup nut is threadedly connected to the anchor cup, and the anchor cup nut is supported on the anchor plate; a tie rod is provided at the top of the anchor cup, the tie rod is threadedly connected to the anchor cup, and a top plate and a tie rod nut are sequentially provided on the tie rod from bottom to top, the tie rod nut being threadedly connected to the tie rod; a combined jack is provided between the top plate and the anchor plate, and the top plate is supported on the combined jack; when the combined jack is activated, it pushes the top plate upward, causing the tie rod to move upward, rotating the anchor cup nut and the tie rod nut, and after repeated operation, the anchor cup is tensioned into place.
[0005] The tie rod is a hollow structural component.
[0006] The inner wall of the pull rod has internal threads.
[0007] The combined jacks include multiple jacks, which are evenly distributed around the anchor cup. The bottom of each jack is supported on the anchor plate, and the extended ends of each jack abut against the bottom surface of the top plate.
[0008] Compared with the prior art, the advantages of this utility model are: a steel strand finished cable combination tensioning fixture, the tie rod is designed as a sleeve and directly connected to the anchor cup, eliminating the need for a connecting sleeve, the structure is simple, the operation is convenient, and space is saved; four jacks form a combined jack, which meets the tension force requirements. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of a steel strand finished cable assembly tensioning fixture according to an embodiment of the present utility model; Figure 2 for Figure 1 Top view; Figure 3 A schematic diagram showing the anchor cup being tensioned into position; In the diagram: 1. Tie rod, 2. Tie rod nut, 3. Top plate, 4. Jack, 5. Anchor cup nut, 6. Anchor plate, 7. Bridge plate, 8. Anchor cup. Detailed Implementation
[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0011] like Figure 1 As shown, this embodiment of a steel strand precast cable tensioning assembly includes vertically arranged anchor cups 8, with anchor plates 6 passing through the bottom of the anchor cups 8, and the anchor plates 6 are placed on the bridge deck 7. An anchor cup nut 5 is fitted onto the anchor cup 8, and the anchor cup 8 and anchor cup nut 5 are threadedly connected, with the anchor cup nut 5 supported on the anchor plate 6. A hollow tie rod 1 is provided at the top of the anchor cup 8, with internal threads on the inner wall of the tie rod 1, and the tie rod 1 is threadedly connected to the anchor cup 8. A top plate 3 and a tie rod nut 2 are sequentially fitted onto the tie rod 1 from bottom to top, and the tie rod nut 2 is threadedly connected to the tie rod 1, with the tie rod nut 2 supported on the top plate 3. A combined jack is provided between the top plate 3 and the anchor plate 6, and the top plate 3 is supported on the combined jack. Figure 3 As shown, when the combined jack is started, it pushes the top plate 3 to move upward, causing the tie rod nut 2 and tie rod 1 to move upward. Rotating the tie rod nut 2 causes the tie rod 1 to rotate downward. Rotating the anchor cup nut 5 causes the anchor cup 8 to screw into the anchor plate 6. Through repeated operation, the anchor cup is tensioned into place.
[0012] like Figure 2 As shown, the above-mentioned combined jacks include four jacks 4, which are evenly distributed around the anchor cup 8. The bottom of the jacks 4 is supported on the anchor plate 6, and the extended ends of the jacks 4 abut against the bottom surface of the top plate 3.
[0013] The tie rod in this application is designed as a sleeve, which connects directly to the anchor cup, eliminating the need for a connecting sleeve. This design simplifies the structure, makes operation convenient, and saves space. The four jacks form a combined jack, which meets the tension requirements.
[0014] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
Claims
