Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction and relates to a tower body angle steel main material reinforcement structure of a transmission angle steel tower. Background Art

[0002] At present, the reinforcement method of the angle steel main material of the transmission angle steel tower is to connect the angle steel main material with the auxiliary main material angle steel or welded components of the same specification as the main material through clamp bolts to form a component reinforcement method of a combined cross section. The combined cross sections include cross, T-shaped, Y-shaped, polygonal, etc. Although the bearing capacity of the angle steel components has been improved to a certain extent, there are the following problems:

[0003] 1. There are various forms of combined sections, but the design specifications do not give the wind load shape coefficient values ​​of various combined sections, which makes it inconvenient for designers to calculate the shape coefficient of the reinforced angle steel tower.

[0004] 2. The bearing capacity of reinforced components connected by clamp bolts is affected by parameters such as the number of clamps, clamp positions, and bolt preload. The specification does not provide relevant technical parameter requirements, which is inconvenient for designers and construction personnel to use.

[0005] 3. The use of welding to reinforce the main angle steel material greatly increases the difficulty of on-site construction.

[0006] 4. Strengthening the secondary main material increases the wind-blocking area of ​​the tower body main material, that is, increases the wind load on the tower body, thereby increasing the pull-out force of the foundation, and requires a higher economic cost to reinforce the anchor bolts and foundation. Summary of the invention

[0007] In order to overcome the shortcomings of the existing technology, the utility model provides a transmission angle steel tower tower body angle steel main material reinforcement structure, which is easy to install on site, has high construction efficiency, simple calculation method, improves the deformation resistance and stable bearing capacity of the angle steel main material, and the overall stability of the reinforced tower section.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A transmission angle steel tower body angle steel main material reinforcement structure, the reinforcement structure includes an angle steel main material, a U-shaped cross-section auxiliary main material, a connecting plate and a horizontal support angle steel, the U-shaped cross-section auxiliary main material is embedded in the angle steel main material, the connecting plates are arranged at both ends and the middle position of the U-shaped cross-section auxiliary main material, two U-shaped cross-section auxiliary main materials located on the same angle steel main material are fixedly connected by the connecting plates at both ends, and the connecting plates at the middle position of the U-shaped cross-section auxiliary main material reinforced by the angle steel main materials at the diagonal positions of the tower body are connected by the horizontal support angle steel.

[0010] Furthermore, the connecting plate at the middle position is fixedly connected to the end of the horizontal supporting angle steel by bolts.

[0011] Furthermore, the middle parts of the two horizontal supporting angle steels reinforced by the angle steel main material at the same diagonal position are fixedly connected by bolts.

[0012] Preferably, the two U-shaped section auxiliary main materials located on the same angle steel main material are connected by connecting plate bolts at both ends, that is, the two connecting plates at the upper end and the lower end are fixedly connected by bolts.

[0013] More preferably, the connecting plates are welded to both ends and a middle position of the U-shaped cross-section secondary main material.

[0014] The beneficial effects of the utility model are mainly manifested in:

[0015] 1. The U-shaped section auxiliary main material is embedded in the angle steel main material. The U-shaped section auxiliary main material and the connecting plate can be welded in the factory. The U-shaped section auxiliary main materials and the horizontal supporting angle steel are connected by bolts, which is convenient for on-site installation and has high construction efficiency.

[0016] 2. The U-section secondary main material is embedded in the angle steel main material, without changing the shape of the angle steel main material, that is, the value of the angle steel body coefficient is not changed.

[0017] 3. The U-shaped section auxiliary main material can restrain the deformation of the angle steel main material, thereby improving the deformation resistance and stable bearing capacity of the angle steel main material.

[0018] 4. The U-shaped section secondary main material and horizontal support angle steel can reduce the calculated length of the tower body angle steel main material, thereby improving the stable bearing capacity of the compressed angle steel main material, and the calculation method is simple.

[0019] 5. All U-section secondary main materials form a whole through horizontal support angle steel to improve the stability of the reinforced tower section.

[0020] 6. Compared with other reinforcement methods that add secondary main materials, this reinforcement method increases the wind-blocking area of ​​the tower body very little, and can reduce the amount of steel and concrete used for anchor bolts and foundation reinforcement.
