A lightweight material reinforcer for an iron tower

Abstract

The present invention provides a lightweight material reinforcer for an iron tower. The iron tower is composed of a truss tower structure consisting of a main material angle steel and a secondary material angle steel. The feature is that a number of reinforcers are installed on the main material angle steel at preset intervals. The reinforcer includes an L-type clamping plate and an inner section plate. The L-type clamping plate and the inner section plate are bolted to clamp the main material angle steel. The inner section plate includes an upper section plate inclined upward at an angle of 45° and a horizontal lower section plate. The contact surfaces between the upper section plate and the lower section plate and the main material angle steel are in an arc shape. The beneficial effects of the present invention include: improving the compressive stability of the main material angle steel, no need to drill holes on the original tower, convenient construction operation, not easy to accumulate snow and ice, and prestressing can be applied to the two limbs of the main material angle steel during installation. When the main material angle steel is under pressure, the reinforcer can play a clamping role more quickly to prevent the main material angle steel from deforming and becoming unstable.

Description

Technical Field

[0001] The invention relates to the installation of electric wires, in particular to a lightweight material reinforcer for an iron tower. Background Art

[0002] With the extensive application of new energy technologies, the grid connection of photovoltaic and wind power stations, and the charging of new energy vehicles, the current passing through some high-voltage lines has increased significantly, and it is necessary to replace wires with larger cross-sections. Large-section wires impose a greater load on the tower, which exceeds the load capacity of the original tower. Replacing the tower with a larger load capacity requires re-expropriation of land for civil construction, which is expensive and has a long construction period. Reinforcement of the original tower can greatly save the cost of building high-voltage lines and save construction time. However, the existing reinforcement methods have the disadvantages of poor reinforcement effect and excessive weight of additional materials.

[0003] After the existing overhead transmission lines have been in operation for a period of time, the design standards need to be improved due to the construction of highways or high-speed railways below the lines, and the wires need to be re-erected or the towers need to be reinforced. Tower reinforcement usually involves reinforcing the main materials. The reinforcement device with additional secondary main materials has greatly increased the weight of the tower, reducing some of the reinforcement effects. In addition, due to the ice-covered climate conditions, the reinforcement device increases the accumulation of ice, which increases the load on the tower to a certain extent. Summary of the invention

[0004] The technical problem to be solved by the patent of this invention is to provide a lightweight material reinforcer for an iron tower, to reinforce the main material of the iron tower body, and to improve the compressive stability of the main material angle steel. There is no need to drill holes in the original tower material, and it is only necessary to adapt the reinforcer according to the model of the main material, which makes the construction operation convenient.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A lightweight material reinforcer for an iron tower, the iron tower is composed of a truss tower structure consisting of a main material angle steel and a secondary material angle steel, characterized in that a plurality of reinforcers are installed on the main material angle steel at preset intervals, the reinforcer comprises an L-shaped clamping plate and an inner section plate, the L-shaped clamping plate and the inner section plate are connected with bolts to clamp the main material angle steel, the inner section plate comprises an upper section plate inclined upward at an angle of 45° and a horizontal lower section plate, the contact surfaces of the upper section plate and the lower section plate with the main material angle steel are in an arc shape, and the space enclosed by the upper section plate, the lower section plate and the main material angle steel is filled with foam plastic.

[0007] Preferably, the reinforcer material is aluminum alloy.

[0008] Preferably, the preset spacing is 300-600 mm.

[0009] Beneficial effects of the invention: The patent of the present invention is used to reinforce existing transmission towers to improve the bearing capacity and disaster resistance of the towers. Compared with the existing transmission tower reinforcement method, it has the following advantages. First, it improves the compressive stability of the main material angle steel, improves the strength of the tower, and at the same time greatly reduces the weight of the reinforcement material, reducing the additional load applied to the tower by the reinforcement material. Second, there is no need to drill holes in the original tower. Third, the construction operation is convenient. Fourth, it is not easy to accumulate snow and ice, reducing the additional load on the tower in ice disaster weather. Fifth, the contact surface between the upper section plate and the lower section plate and the main material angle steel is arc-shaped, and prestress can be applied to the two limbs of the main material angle steel during installation. When the main material angle steel is under pressure, the reinforcer can play a clamping role more quickly to prevent the main material angle steel from deforming and becoming unstable.

[0014] See also Figure 1~Figure 3 As shown, a lightweight material reinforcer for an iron tower is installed with a plurality of reinforcers 2 at a preset spacing on the main material angle steel 1. The reinforcer 2 includes an L-shaped clamping plate 4 and an inner section plate 3. The L-shaped clamping plate 4 and the inner section plate 3 are connected to clamp the main material angle steel 1 through bolts 5. The installation can be performed without drilling holes in the main material. The inner section plate 3 includes an upper section plate 7 tilted upward at an angle of 45° and a horizontal lower section plate 6. The upper section plate 7 tilted upward at an angle of 45° can reduce snow accumulation and ice formation. The contact surfaces of the upper section plate 7 and the lower section plate 6 with the main material angle steel 1 are arc lines 8. Prestress can be applied to the two limbs of the main material angle steel during installation. When the main material angle steel is under pressure, the reinforcer can play a clamping role faster to prevent the main material angle steel from deforming and becoming unstable. The reinforcer material is aluminum alloy. The space enclosed by the upper section plate 7, the lower section plate 6 and the main material angle steel 1 is filled with foam plastic (not shown). The preset spacing is 300~600mm.
