Technical Field

[0001] The utility model relates to the technical field of reinforcement, in particular to a carbon fiber reinforcement structure for an electric pole tower. Background Art

[0002] At present, there are two solutions for the reinforcement of iron towers. The first is to use angle steel to reinforce the main material of the iron tower to stabilize the control rods, and change the parallel axis arrangement of the main material to the minimum axis arrangement. The second is to use the same angle steel as the main material to diagonally reinforce the main material. The biggest disadvantage of these two methods is that they greatly increase the weight of the iron tower and increase the moment of the foundation surface. They solve the load-bearing problem of the tower, but also bring new problems and fail to effectively ensure the stability of line operation. Utility Model Content

[0003] The purpose of the utility model is to provide a carbon fiber reinforcement structure for a power pole tower, which improves the strength of the reinforcement by the higher specific strength and specific modulus of the carbon fiber reinforcement. At the same time, the carbon fiber has the advantages of light weight and high strength, and has excellent mechanical properties and chemical stability. It reduces the overall gravity of the iron frame after reinforcement. On the basis of the defects of traditional reinforcement methods, it can effectively improve the stiffness and bearing capacity of the original structure, especially significantly improve the fatigue life of fatigue damaged steel structures, and delay the expansion of fatigue cracks, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbon fiber reinforcement structure for a power pole tower, comprising an iron frame of the power pole tower to be reinforced, a carbon fiber reinforcement piece being adhered to the outer side of the iron frame, a plurality of sets of locking pieces being clamped on the outer sides of the iron frame and the carbon fiber reinforcement piece, the locking pieces comprising buckles and fastening bolts, a through hole being provided on the outer side of the buckle, and an internal threaded tube being fixed to the inner cavity of the through hole, one end of the internal threaded tube extending outward, the fastening bolt being threadedly connected to the inner cavity of the internal threaded tube, and one end of the fastening bolt being adhered to the outer side of the carbon fiber reinforcement piece.

[0005] Preferably, the iron frame comprises two integrally formed and vertical iron plates, one end of the iron plate is integrally formed with an arc plate, and the carbon fiber reinforcement is attached to the corner of the intersection of the iron plates away from the arc plate.

[0006] Preferably, the inner side of the carbon fiber reinforcement is provided with an arc chamfer, and the buckle is attached to the edge of the arc chamfer.

[0007] Preferably, a plurality of groups of support plates are fixed to the outer side of the buckle, the outer side of the support plates are arranged in a smooth arc shape, and the support plates and the fastening bolts are distributed in a staggered manner.

[0008] Preferably, the support plates of the two groups of locking members fit together, and two groups of fastening bolts are arranged between the two groups of support plates. The two groups of fastening bolts are diagonally distributed on the outside of the buckle.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model installs the carbon fiber reinforcement piece on the iron frame, uses the strength and bending resistance of the carbon fiber reinforcement piece to support the iron frame, and then uses locking pieces to fix the carbon fiber reinforcement piece and the iron frame, thereby ensuring the stable support of the iron frame by the carbon fiber reinforcement piece and delaying the expansion of fatigue cracks. On the basis of the defects of traditional reinforcement methods, the utility model can effectively improve the stiffness and bearing capacity of the original structure. At the same time, compared with traditional metal reinforcement pieces, the weight proportion of the carbon fiber reinforcement piece is reduced, thereby reducing the load on the power tower.

[0011] 2. The utility model provides an arc chamfer on the inner side of the carbon fiber reinforcement to improve the bending resistance of the carbon fiber reinforcement itself, so as to prevent the carbon fiber reinforcement itself from being easily deformed and unable to effectively support the iron frame.

[0019] By installing the carbon fiber reinforcement 2 on the iron frame 1, using the strength and bending resistance of the carbon fiber reinforcement 2 to support the iron frame 1, and then using the locking piece 3 to fix the carbon fiber reinforcement 2 to the iron frame 1, the carbon fiber reinforcement 2 can be guaranteed to stably support the iron frame 1 and delay the expansion of fatigue cracks. On the basis of the defects of traditional reinforcement methods, the stiffness and bearing capacity of the original structure can be effectively improved. At the same time, compared with traditional metal reinforcements, the weight of the carbon fiber reinforcement 2 is reduced, which reduces the load on the power tower.

[0020] The iron frame 1 includes two integrally formed and vertical iron plates 101, one end of the iron plate 101 is integrally formed with an arc plate 102, and the carbon fiber reinforcement 2 is attached to the corner away from the arc plate 102 at the intersection of the iron plates 101.

The support plate 6 and the fastening bolts 302 are staggered. The buckle 301 is supported by the setting of the support plate 6 to prevent the buckle 301 from being deformed under the support of the fastening bolts 302. The supporting force of the support plate 6 is utilized to ensure that the fastening bolts 302 stably support the carbon fiber reinforcement 2, so that the carbon fiber reinforcement 2 fits the outside of the iron frame 1.
