One: Common tower type
Steel tower masts are usually divided into the following categories from the type of steel material:
1. Angle steel tower
The main material and the web rod are mainly made of angle steel. According to the different section variables, there are triangular towers, quadrangular towers, pentagonal towers, hexagonal towers, and octagonal towers. The most commonly used communication is the quadrangular tower and the triangular tower
2. Steel pipe tower
The main material is steel pipe, and the inclined material is made of angle steel or steel pipe. The same angle steel tower is classified according to the cross-sectional shape. The three-tube tower and the four-tube tower are the most used for communication.
3. Single-tube tower (single-tube tower)
The entire tower body is a cantilevered structure made of a single large-diameter steel pipe
4. Mast or stay tower
A towering steel structure consisting of a central column and fiber ropes (or cables).
Two: Common tower types
1. Single-tube tower:
Definition: The single-tube tower is a self-supporting high-rise steel structure with a single large-diameter conical steel pipe as the main structure. The cross-section of the tower body can be processed into two types: circular and regular polygons.
Main features: The cross section of the tower body of the plug-in single-tube tower is generally 12-sided to 16-sided, using external climbing, and the climbing ladder is set outside the tower body
Applicable height: 40m, 45m, 50m
2. Three-pipe tower
Definition: Three-pipe tower refers to a self-supporting high-rise steel structure with a tower column made of steel pipes and a triangular section of the tower body.
Main features: The tower column of the three-tube tower is made of steel pipes, and the cross-section of the tower body is triangular, which is a towering steel structure different from angle steel.
Applicable height: 40m, 45m, 50m
3. Angle steel tower
Definition: Angle steel tower refers to a self-supporting towering steel structure made of angle steel
Main features: The tower body of the angle steel tower is assembled with angle steel profiles, which are connected by bolts, and the welding workload is small. Applicable heights: 45m, 50m, 55m
4. Landscape Tower
Definition: The landscape tower is a self-supporting high-rise steel structure with a single large-diameter conical steel pipe as the main structure, and the landscape shape is set in consideration of the requirements; the cross section of the tower body can be processed into two types: circular and regular polygons. Inner flange connection as a whole
Main features: Inner flange landscape tower, the cross-section of the tower body is circular, using internal climbing, the climbing ladder is set inside the tower body, the landscape shape can be flexibly set according to the application scene, the owner’s requirements, etc. Applicable heights: 30m, 35m
5. Street light pole
Definition: Street light pole is a special kind of landscape tower, which is widely used on both sides of municipal roads, scenic spots, parks, squares, etc.
Main features: The cross section of the tower body is circular. The shape can be flexibly set according to the application scene, the owner’s requirements, etc. Applicable height: 20m
6. Roof cable mast
Definition: Roof-stayed mast refers to the towering steel knots constructed on the roof of an existing building and composed of uprights and cables. Main features: The cable-stayed mast is a non-self-supporting tower, and the tower body cannot bear the load independently. Apply pre-tension to provide the rigidity of the cable tower Applicable height: 15m
7. Portable tower house integration
Definition: Portable tower room integration is a towering structure that integrates a computer room and tower mast for wireless communication. It is mainly composed of a tower body, a computer room system and a counterweight system.
Main features: fast integration and easy relocation Applicable height: 20m-35m
8. Bionic tree
Definition: Bionic tree is a special kind of landscape tower, which is widely used in scenic spots, parks, squares, etc. Its landscape shape is tree shape
Main features: The cross section of the bionic tree tower body is circular, using internal climbing, and the climbing ladder is set inside the tower body. The tree shape can be flexibly set according to the application scene, the owner’s requirements, etc. Applicable height: 20m-35m
9. Ground cable tower
Definition: Guyed tower is a non-self-supporting towering steel structure composed of tower columns and guyed wires
Main features: The cable tower is a non-self-supporting tower. The tower body cannot bear the load independently. It is necessary to increase the pulling fiber to resist the external load and apply pre-tension through the pulling fiber to provide the rigidity of the cable tower. Applicable height: 20m-30m
10. Roof heightening
Definition: Roof-increasing frame refers to the towering steel structure of lattice type built on the roof of an existing building Main features: The height is generally not too high, and the section is generally a regular polygon. Applicable height: 10m-20m
11. Roof pole
Definition: A pole with support erected on the roof of an existing building for direct antenna installation
Main features: A roof pole is generally only used to install a pair of antennas: According to the connection form with the roof, it is divided into two types: planting bar pole and counterweight pole Applicable height: 2m-8m
12. Roof Landscape Tower
Definition: The roof landscape tower is a roof tower mast set on the roof considering the landscape needs. Main features: Flexible shape to meet landscape needs Applicable height: 8m-18m
13. Beautify the antenna
Definition: The beautification antenna is an antenna pole with a camouflage cover set on the roof. The setting of the camouflage cover considers the integration with the surrounding environment. Common cover shapes include chimneys, water tanks, and outdoor units of air conditioners.
14. H rod
Definition: The H-pole in communication line engineering is called by the image of the layout of electric masts, equipment mounting brackets, and platforms, and it is a convention.
Main features: H pole is generally two masts generally high.
Three: tower type distinction tips
1. The difference between angle steel tower and steel pipe tower: angle steel tower is angle steel (triangular steel); tube tower is tubular steel, round tube steel
2. The difference between mast and tower: usually below 20m is pole, above 20m is tower: roof is pole,
The ground is the tower.
3. The height-increasing frame is a towering steel structure of lattice type, the height is generally not too high (10m-20m), and the section is one
It is generally a regular polygonal section. The ground is elevated for the ground, and the roof is elevated for the roof.
