Installation of basketball stand
Before installation, the basketball stand should be set out on the court so that the line of the basketball court can be drawn before installation.
For standard basketball stands, the distance between the hoop and the ground is 3050mm, the distance between the backboard and the ground is 2900mm, and the distance between the backboard and the bottom line is 1200mm. Mobile basketball stands are relatively simple to install, but installation personnel are required to install and debug them. Here we mainly describe the installation of buried basketball stands.
The main thing to pay attention to is the location of the buried pit. Before drilling, we need to know the arm length of the basketball frame. Take the round tube basketball frame that our company often installs as an example. The arm length of this basketball frame is 1800, and the distance from the bottom line to the column is 600. The required hole width is 700mm * 700mm, 800mm. Here we need to explain that the hole is dug, Since the distance between the hoop and the ground is 3050mm, a rope is used to cover the hoop during installation. The rope length is just 3050mm. If the basketball stand is buried in the pit, the rope should just contact the ground. The distance between the excavated pit and the bottom line is 350mm at this time.
After the basketball stand is placed in the pit and the position is determined, the pit shall be filled with concrete. It shall not be used within three days. The backboard generally has 2-4 connecting rods, which are mainly used to adjust the angle of the backboard and stabilize the backboard.
For the special installation position of some basketball stands, such as roof or roof, we can also use embedded Bolt By setting the flange After being buried in the pit and filled, connect the bottom of the basketball stand with the embedded parts.
The embedded parts of the basketball stand shall not be less than 400mm × 400mm, and shall be buried 1m below. The embedded parts shall have certain corrosion resistance, anti acid and anti alkali functions. The upper and lower fixation of the embedded parts shall be firm, and the fastening screws shall be hot-dip galvanized.
Maintenance of basketball stand
Because the indoor basketball rack does not need to worry about wind and rain, the steel is not easy to rust, but it also has disadvantages. Due to the lack of natural washing by rain, the backboard is easy to be dirty after long use, and it can be cleaned with a longer mop.
The outdoor basketball stand steel is exposed for a long time. Once the paint falls off, the steel is easy to rust. If the paint surface is broken, it should be repaired in time. Once the basketball stand is seriously rusted and perforated, it should be stopped immediately.
The backboard will not be hit by bricks and stones under normal use.
No dunking is allowed for non spring hoops. If the hoops are inclined or broken. Contact the manufacturer for maintenance or replacement.
