Читать книгу Building Your Own Dock - Sam Merriam - Страница 14

Plain and simple, this dock section is framed using nominal 2x6 (38- by 140-millimeter) stringers and 1x6 (19- by 140-millimeter) decking. With its timbers spaced about 2 feet (60.96 centimeters) apart, the capacity is sufficient for 40 pounds per square foot (1,900 N/m²). If made completely with PT wood, a 4-foot-wide by 10-foot-long (1.22- by 3.05-meter) section as shown here has a weight of about 200 pounds (90.8 kilograms). Use cedar decking on the PT frame and the weight drops to about 170 pounds (77.18 kilograms). Increase the frame to 2x8 (38 x 184 millimeters); with cedar decking it would weigh about 210 pounds (95.24 kilograms).
