59 visitsWhen installing an underground basketball stand, the standard size of the edge of the basketball stand (post) from the end line of the basketball court is 60 cm. This size is the core parameter to ensure the compliance of the basketball stand installation and the safety of sports. The following is a detailed explanation:
1. Why is a 60 cm offline distance required?
Comply with sports rules
The International Basketball Federation (FIBA) and domestic standards stipulate that the basketball stand posts must be away from the end line to prevent players from being injured when colliding. The 60 cm spacing provides players with enough buffer space to reduce accidental injuries caused by collisions with basketball stands.
Ensure the safety of shooting and rebounding
When shooting or competing for rebounds, players may lean toward the end line. The 60 cm distance can prevent players from hitting the basketball stand posts due to inertia, while ensuring that the vertical projection of the rebound does not interfere with activities in the end line area.
Adapt to the requirements of the venue buffer zone
A 2-meter safety buffer zone must be reserved outside the end line of the basketball court (for players running, referees, etc.). The 60 cm offline distance is part of the buffer zone design to ensure that the basketball stand does not take up additional space after installation.
2. Other key dimensions during installation
Pre-buried pit dimensions
Common specifications: 70 cm long × 70 cm wide × 80 cm deep (or 80 cm long × 80 cm wide × 70 cm deep, please refer to the product manual for details).
Function: The pre-buried pit is used to fix the base of the basketball stand. After the concrete is filled, it needs to be cured for 3-5 days to ensure firmness.
Backboard height from the ground
Standard value: The lower edge of the backboard is 290 cm from the ground, and the upper edge of the basket ring is 305 cm from the ground.
Requirement: The backboard must be installed vertically, and the five points must be evenly stressed (especially the tempered glass backboard) to avoid cracking due to uneven stress.
Basketball stand arm span and venue layout
Arm span selection: The arm span of a fixed basketball stand is usually 160 cm, 180 cm or 225 cm. For example, if the arm span is 160 cm, the fixing point of the basketball stand should be 35 cm outside the end line (calculation method: 160 cm - 120 cm (backboard projection distance) - 5 cm (safety margin)).
Minimum venue size: The length of the basketball stand placement area must be ≥30 meters (including buffer zone) and the width must be ≥15 meters to accommodate a standard basketball court and safe activity space.
3. Installation precautions
Horizontal calibration
The installation ground may be uneven. You need to use a level ruler to test around the basketball stand pipe wall to ensure that the frame is vertical to avoid tilting and causing the backboard to break or the shooting trajectory to deviate.
Concrete maintenance
After the pre-buried pit is filled with concrete, it is necessary to wait for 3-5 days for it to completely dry and solidify before installing the main structure of the basketball stand (such as columns and backboard) to prevent unstable fixation due to the concrete not being completely dry.
Anti-rust treatment
The columns and metal parts of the basketball stand need to be electrostatically sprayed or thickened with anti-rust technology to extend the service life, especially for outdoor humid environments.
Backboard protection
The lower edge of the tempered glass backboard needs to be covered with polyurethane protective strips to prevent players from being injured when colliding and reduce wear on the edge of the backboard.
