Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of structural reinforcement in civil engineering, and in particular relates to a multi-directional energy dissipation reinforcement device for angle steel of a transmission tower. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] As an important load-bearing component, angle steel is widely used in steel structure construction, especially as the main structural material and diagonal material, playing an irreplaceable role in angle steel towers and angle steel-circular tube combined towers. Angle steel components are prone to rust when exposed to the natural environment for a long time, and are prone to deformation or damage to varying degrees in harsh environments such as hurricane loads and earthquakes, resulting in low overall bearing capacity and reduced stiffness of the transmission tower. For some transmission towers that have exceeded their service life and have many damaged rods but can still continue to bear loads, they account for a large proportion of the entire power grid project, and demolition and reconstruction will inevitably cause a great waste of time and financial resources, resulting in huge losses; in contrast, the use of reasonable and effective reinforcement methods is an ideal choice, while traditional reinforcement methods often require drilling or welding of the original angle steel, which is not only difficult to operate, but also easy to weaken the cross section of the angle steel and cause stress concentration when subjected to force; therefore, it is of great practical significance to design a non-destructive reinforcement form that is simple in form and does not damage the original components.
[0004] At present, domestic and foreign scholars have conducted relevant research on angle steel reinforcement, proposed different reinforcement methods and conducted real-type test verification, such as T-type reinforcement, Y-type reinforcement and FRP new material reinforcement, but the reinforcement form is relatively rigid, and the clamp form is complex, which makes it difficult to implement the reinforcement of the angle steel located in the middle and upper part of the transmission tower. Therefore, in order to reasonably process components and perform on-site operations, the reinforcement form must be simple and the original angle steel cannot be drilled or welded at high altitude. However, the simple clamp form consumes a lot of materials, and it is difficult to ensure the effective improvement of bearing capacity without drilling and welding. Utility Model Content

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0028] Example 1
[0029] In a typical implementation of the present invention, Figure 1-4 As shown, a multi-directional energy dissipation reinforcement device for the angle steel of a transmission tower is provided, comprising a clamp 3, a fixed steel plate 1, a first reinforcement device 4 and a second reinforcement device 5; the clamp 3 and the fixed steel plate 1 are connected into an integral structure, and are clamped around the periphery of the reinforced angle steel 6; the second reinforcement device 5 is arranged between the reinforced angle steel 6 and the fixed steel plate 1, and the second reinforcement device 5 is filled with a damping liquid 7; the first reinforcement device 4 is fixed to the inner wall of the outer shell of the second reinforcement device 5; a damping rod is arranged on the first reinforcement device 4, and a movable piston 12 is arranged on the second reinforcement device 5, and the reinforced angle steel 6 is energy-dissipated and reinforced in different directions by the damping rod 9 and the movable piston 12 in cooperation with the damping liquid 7.
[0030] In this embodiment, the clamp 3 and the fixed steel plate 1 are connected to form a right-angled triangle structure, wherein the clamp 3 is two right-angled sides perpendicular to each other, and the two right-angled sides are fixedly connected by bolts 2, and the fixed steel plate 1 is a hypotenuse, and both ends of the fixed steel plate 1 are connected to the clamp 3 by bolts 2.
[0031] The inside of the right-angled triangle formed by the clamp 3 and the fixed steel plate 1 is the inner side, and the outside is the outer side. The inner wall surface of the clamp 3 fits with the outer wall surface of the reinforced angle steel 6, and the two end surfaces of the right-angle surface of the reinforced angle steel fit with the inner wall surface of the fixed steel plate 1. The fixed steel plate is pasted with a rubber pad on the part in contact with the reinforced angle steel, so that the contact part of the reinforced angle steel maintains good mechanical properties.
[0032] In this embodiment, friction pads 14 are provided at the positions where the second reinforcement device 5 contacts the reinforced angle steel 6 and the fixed steel plate 1. The installation of friction pads can increase the pre-tightening force between different components, making the device tighter and less likely to loosen. In addition, friction pads are also provided on the wall surface where the clamp 3 contacts the reinforced angle steel 6. In this case, the friction pads are L-shaped friction pads that match the shape of the reinforced angle steel.
[0033] In this embodiment, the cross-section of the shell of the second reinforcement device 5 is a hexagonal structure, the shell is filled with damping fluid 7, and the three spaced outer wall surfaces of the shell are respectively in contact with the inner wall surface of the fixed steel plate 1 and the two inner wall surfaces of the reinforced angle steel 6.
[0034] like Figure 2 As shown, the damping rod 9 on the first reinforcement device 4 is a J-shaped structure. Setting the damping rod to a J-shape can increase its contact area with the damping fluid, so that it can better reduce vibration and dissipate energy; and multiple other energy dissipation devices can be installed on its straight arm part to achieve a joint effect. There are two damping rods 9 on each first reinforcement device 4. One end of the two damping rods 9 is hinged by a hinged support 8. The hinged support 8 is fixedly mounted on the inner wall of the outer shell of the second reinforcement device 5. The ends of the two damping rods 9 with hooks are arranged back to back. When the structure vibrates or deforms, it drives the J-shaped damping rod 9 to move, and by moving in the damping fluid and colliding with each other, it plays an energy dissipation role.
[0035] Furthermore, a plurality of elastic energy-absorbing rods 10 are fixedly installed at intervals on the damping rod 9. The elastic energy-absorbing rods are arc-shaped structures and are made of materials with good elastic-plasticity, such as mild steel, fibrous materials, etc., to better achieve energy-absorbing effects. A plurality of the first reinforcement devices are arranged at intervals on the inner wall of the outer shell of the second reinforcement device.
[0036] In this embodiment, the second reinforcement device 5 is provided with a plurality of parts in the length direction of the reinforced angle steel, such as Figure 3 As shown, the movable pistons 12 in two adjacent second reinforcement devices 5 are connected by a connecting rod 13. The movable piston 12 is located in the outer shell of the second reinforcement device 5. The movable piston 12 is covered with small holes to achieve better vibration reduction and energy dissipation. The movable piston can slide inside the second reinforcement device 5.
[0037] Furthermore, the shells of two adjacent second reinforcement devices 5 are connected via at least one damping energy dissipation rod 11, and the damping energy dissipation rod 11 contains a piston, a connecting rod and a damping fluid.
[0038] In this embodiment, a plurality of clamps 3 can be provided according to the length of the angle steel, and are arranged on the outside of the reinforced angle steel 6 .
[0039] In this embodiment, the number of the reinforced angle steel 6 connected to the bolts 2 fixing the steel plate 1 is four or more.
[0040] In this embodiment, the damping fluid of the reinforcement device adopts high-density viscous damping fluid.
[0041] The installation method of the transmission tower angle steel multi-directional energy-absorbing reinforcement device provided in this embodiment is as follows: first, complete the assembly between the small components, such as installing the first reinforcement device inside the second device and filling it with damping fluid, then installing the movable piston and the damping energy-absorbing rod, and placing the assembled device between the two limbs of the reinforced angle steel, and finally installing the clamp so that the reinforcement device and the reinforced angle steel form a whole.
[0042] The working principle of the multi-directional energy-absorbing reinforcement device for the angle steel of the transmission tower provided in this embodiment is as follows: when the reinforced angle steel is subjected to stress in different directions and produces deformation and movement, its deformation is first restricted by the fixed steel plate and the clamp, and the vibration is transmitted to the reinforcement device, and then the damping energy-absorbing rod and the second reinforcement device perform damping and energy-absorbing effects. As the damping fluid oscillates, the J-shaped damping rod in the first reinforcement device moves, and drives the elastic energy-absorbing rod to move, and the two achieve reinforcement through mutual collision and damping energy-absorbing. In summary, the three together achieve reinforcement of the original angle steel.
[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
