Lattice for draining waste water of swimming pool, has rope extended through opening formed in spacer and channel formed in UV sunlight and chemical erosion-resistive bar, using which bars and spacers are connected
摘要
<p>The lattice has several UV sunlight and chemical erosion-resistive bars (10) each provided with a channel (12) extended along its transverse direction. Several spacers (20) are placed between adjacent bars, provided with an opening (22) corresponding to the channel provided in the bars. The bars and the spacers are connected using a rope (30) extended through the opening formed in the spacer and channel formed in the bar. An independent claim is included for method for forming lattice.</p>
