Tempered Glass Backboard Installation Key Points and Introduction by Cangzhou Haoran Sports Equipment Co., Ltd.
I. Core Key Points for Tempered Glass Backboard Installation
* **Connection Point Plane and Uniform Stress Distribution:** All five connection points must be strictly on the same plane to ensure uniform stress distribution and prevent backboard breakage due to localized stress concentration.
* **The backboard arm, backboard, and rim must be in a straight line.** The backboard arm and rim must not directly contact the glass backboard to prevent impact force from being directly transmitted to the glass surface.
* **Material and Tool Requirements:**
* **Connecting Parts:** Use 304 stainless steel bolts (e.g., M12×60) with neoprene rubber washers to avoid direct metal-glass contact and reduce the risk of wear.
* **Sealing Treatment:** After installation, seal the connection points with silicone sealant (e.g., for composite fiberglass backboards) to prevent rainwater seepage and internal corrosion.
* **Special Tools:** Use a torque wrench (set to 35 N·m), vacuum suction cup (load capacity ≥ 150 kg), etc., to ensure installation accuracy and safety. Installation Process and Acceptance Standards
Sequence: Frame → Column → Extender Arm → Rear Tie Rod → Backboard → Hoop → Upper/Lower Tie Rod → Add Counterweight.
Verticality and Horizontality: Backboard verticality deviation ≤ 1mm/m, horizontality deviation ≤ 2mm. Use a feeler gauge to check gap uniformity (gap 5mm±1mm).
Wind Pressure Resistance: Simulate 1.5 times the design wind pressure (e.g., 0.55kN/m²) test; maximum deflection ≤ L/200 (L is the shorter side length of the glass); no residual deformation after unloading.
Safety Certification: Glass must comply with GB 15763.2-2005 standard; after breakage, it should form obtuse-angled particles (particle count ≥ 40 particles/25mm×25mm).
Construction Environment and Protection
Site Preparation: Clear obstacles within a 5m radius, lay 50mm thick wooden scaffold boards (bearing capacity ≥ 2kN/m²), and erect full-span scaffolding (upright spacing 1.2m×1.2m).
Temporary Power Distribution: Three-level power distribution with two-level protection; leakage current ≤30mA, operating time ≤0.1s.
Personnel Protection: Equipped with double-hook safety belts (static load test ≥15kN), fall arrestors (effective length 3m), and insulated gloves (withstanding voltage 380V).
