Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance construction, in particular to a rotatable tension rod. Background Art

[0002] A cable-stayed bridge is a modern bridge structure whose primary feature is the stable structural system connected to the bridge deck by cables. Due to their long spans, beautiful appearance, and economical and practical construction, cable-stayed bridges are widely used around the world. However, because cables are susceptible to environmental and load factors during use, their performance can gradually deteriorate or even fail. To ensure the safety and proper operation of cable-stayed bridges, they require regular inspection and maintenance, and replacement when necessary.

[0003] The tensioning rod is an important device in the replacement process of the inclined cable. The tensioning rod tensions or releases the cable force through the jack, thereby completing the installation or removal of the inclined cable. It is found in engineering practice that when the inclined cable is relatively long, under the action of gravity, the inclined cable will have a large sag, so that the end of the inclined cable is far away from the guide tube. When using traditional tensioning rods for construction, the length of the tensioning rod often cannot meet the construction requirements. If the tensioning rod is extended, its length will be limited due to the limited space in the tower, which will also bring inconvenience to the construction and affect the construction efficiency. At the same time, if the existing steel rod tensioning rod is too long, due to its high rigidity, it is not conducive to the smooth progress of construction work during the replacement of the inclined cable.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation. Therefore, they cannot be understood as a limitation on the present invention.

[0021] In addition, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] See also Figure 1 As shown, an embodiment of the present invention provides a rotatable tension rod, comprising a first connecting segment 1 and a second connecting segment 2. The first and second connecting segments 1 and 2 are detachably connected by at least one set of rotational tension segments 3, each comprising a third connecting segment 31 and a fourth connecting segment 32, which are rotatably connected via a connector.

[0023] During installation, according to the on-site length requirements, multiple sets of corner tensioning sections 3 are installed in sequence between the No. 1 connecting section 1 and the No. 2 connecting section 2 to make the total length reach the required length. Figure 4As shown, the No. 1 connecting segment 1 is connected to the tensioning rod connecting sleeve 5, and the tensioning rod connecting sleeve 5 is further connected to the inclined cable anchor cup, thereby playing the role of pulling and tensioning the inclined cable. The No. 2 connecting segment 2 is connected to the tensioning jack 6, thereby forming a tensioning device together with the multi-section rotatable tensioning rod. After fixing the device, the tensioning jack 6 is used to apply force. After the tensioning of one section of cable is completed, the redundant tensioning rod is removed and the tensioning work is continued, which plays the role of uninterrupted tensioning of the cable-stayed bridge cable. In addition, since the No. 3 connecting segment 31 and the No. 4 connecting segment 32 are rotatably connected by a connecting piece, the No. 3 connecting segment 31 and the No. 4 connecting segment 32 can be rotated arbitrarily.

[0024] See also Figure 2 As shown, one end of the No. 1 connecting segment 1 is provided with a No. 1 bolt segment 11 and a No. 1 annular rib 12 clamped on the outer periphery of the No. 1 bolt segment 11 by a caliper. By rotating the No. 1 annular rib 12, the No. 1 bolt segment 11 can be driven to rotate synchronously. One end of the No. 2 connecting segment 2 is provided with a No. 2 bolt hole segment 21 and a No. 2 annular rib 22 clamped on the outer periphery of the No. 2 bolt hole segment 21 by a caliper. By rotating the No. 2 annular rib 22, the No. 2 bolt hole segment 21 can be driven to rotate synchronously, which facilitates the loading and unloading between the No. 1 connecting segment 1 and the No. 2 connecting segment 2 and other components.

[0025] Similarly, one end of the No. 3 connecting segment 31 is provided with a No. 3 bolt hole segment 311 and a No. 3 annular rib 312 clamped on the outer periphery of the No. 3 bolt hole segment 311 by a caliper. By rotating the No. 3 annular rib 312, the No. 3 bolt hole segment 311 can be driven to rotate synchronously. One end of the No. 4 connecting segment 32 is provided with a No. 4 bolt segment 321 and a No. 4 annular rib 322 clamped on the outer periphery of the No. 4 bolt segment 321 by a caliper. By rotating the No. 4 annular rib 322, the No. 4 bolt segment 321 can be driven to rotate synchronously. The No. 4 bolt segment 321 and the No. 1 bolt segment 11 are matched with the No. 3 bolt hole segment 311 and the No. 2 bolt hole segment 21. By setting the bolt segment, bolt hole segment and annular rib 312, the adjacent bolt segments and bolt hole segments can be installed and disassembled by rotating the annular rib 312 in the opposite direction, and the construction is convenient and quick.

[0026] See also Figure 1 As shown, the connecting member includes two sets of connecting ring assemblies 4 arranged opposite to each other, one set of connecting ring assemblies 4 is arranged at one end of the No. 3 connecting section 31 away from the No. 3 bolt hole section 311, and the other set of connecting ring assemblies 4 is arranged at one end of the No. 4 connecting section 32 away from the No. 4 bolt section 321. Figure 3As shown, the connecting ring assembly 4 includes a U-shaped steel ring 41, a flange 42 and a screw 43. The two ends of the U-shaped steel ring 41 are respectively fixedly connected to a flange 42. The flange 42 is fixedly installed on the end of the No. 3 connecting section 31 or the No. 4 connecting section 32 by a screw 43. The two adjacent U-shaped steel rings 41 are hooked and locked with each other. The U-shaped steel rings 41 can be rotated arbitrarily, so that the entire tensioning rod composed of multiple groups of corner tensioning sections 3 forms a certain curvature in the length direction.

[0027] It can be understood that by providing an end thread 13 at the end of the No. 1 connecting section 1 away from the No. 1 bolt section 11, the No. 1 connecting section 1 is connected to the tension rod connecting sleeve 5 through the end thread 13, which makes loading and unloading convenient and quick.

[0028] The present invention provides a rotatable tensioning rod that can, according to the on-site length requirements, sequentially connect a corresponding number of corner tensioning sections 3 between the first connecting section 1 and the second connecting section 2 to meet the requirements of the construction site for completing the tensioning construction of various lengths of inclined cables. At the same time, the corner tensioning section 3 includes a third connecting section 31 and a fourth connecting section 32, which are rotatably connected by a connecting piece, so that the entire tensioning rod composed of multiple groups of corner tensioning sections 3 forms a certain curvature in the length direction. This avoids the existing steel rod tensioning rod, which is very rigid and is not conducive to the smooth progress of construction work during the inclined cable replacement process. This solves the construction difficulties of the existing inclined cable tensioning, reduces the difficulty of inclined cable tensioning, reduces the tensioning cost, and improves the efficiency of inclined cable tensioning construction.

[0029] The above detailed description of the preferred embodiments of the present invention should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
