1. Product specifications and materials The outstretched arm is 1.8m , one the rim of ring is 3.05M away from the ground, the support were welded by 180x180x4.0mm or 150*150*3mm special high quanlity large rond corners square pipe. Arm was welded by 150x150x3.0mm square pipe. The back pull rod was bended once by 40x40x2.0mm square pipe, The upper fulcrum is once bended theφ32x2.5mm steel pipe on the bending machine ,which avoids the hidden danger of rust caused by welding and welding slag. By adjusting the upper pull rod to adjusted the plane and perpendicularity of the backboard.
2．backboard： Specification: 1800*1050x10 (mm) smc backboard or high-strength tempered glass backboard with high transparency、good weather resistance、 anti-aging、 corrosion resistance、 not easy to blur and other characteristics. and the lower side of the backboard covered with a U-type padding,the height and thickness of before and after the surface are all ≥20mm, bottom thickness ≥50mm, can effectively protect transport It is not hurt to mobilize dunks
3．ring： The backboard is with standard basket ring and Φ18 steel, which is rolled on the automatic tube winding machine. The hoop has good tensile properties and high strength. The use of high-strength stainless steel bolts, nuts and washers is strong, which can prevent loosening in long-term use. The lower rim of the ring is welded with 12 seamless steel tubes with a φ10*2mm, and PE rope is worn inside. The white rope net is evenly suspended on the PE rope in the pipe, and the basket ring is a double spring elastic structure
4．surface treatment The final surface treatment was finished on the automatic spraying line by electrostatic epoxy based powder spraying on the automatic spraying line. The thickness of the coating was 80um to 120um. The product has the advantages of acid and alkali resistance, moisture and heat resistance, anti-aging, beautiful appearance, and the product coating formula does not contain toxic elements, to avoid damaging the health of users.
5. buried instruction Note: Foundation size as shown in the following figure, the size of pile foundation: excavation horizontal size of 800X800mm, depth of 1000mm. The buried part is M18X900 buried hook, the buried flange is 7 holes flange, and the one is two holes near the edge line of the site
* first at the bottom put into 100mm high C20 concrete, and then put the embedded parts into the pit (two buried hooks direction
near the site edge)
* and then injection of concrete 800mm high ,
* fill in the backfill Layer 100mm.
6、fastene r
All fasteners of the
basketball backstop use the Jinyi brand screw, which is a well-known international brand. The surface is hot-dip galvanized to ensure that it will not rust for a long time
