使用说明与常见问题How-to & FAQ

「甲板地板用量计算器」是什么？What is the Decking Calculator tool?

按甲板长宽、板宽、板缝和板长计算需要多少块面板、龙骨数量和螺钉数，含损耗；面板沿长度方向铺设，龙骨垂直于面板按间距排布。Work out deck boards, joists and screws from the deck size, board width, gap and board length, with waste: boards run along the length and joists run across them at the chosen spacing.

如何使用「甲板地板用量计算器」？How do I use the Decking Calculator tool?

在「甲板地板用量计算器」中，填写「甲板长度（英尺，面板方向）」、「甲板宽度（英尺）」、「面板实际宽度（英寸，示例 5.5 = 6 英寸名义板）」、「板缝（英寸）」、「面板长度」等参数，结果会随输入实时计算并显示在下方。In the Decking Calculator: Fill in "Deck length (ft, board direction)", "Deck width (ft)", "Actual board width (in, example 5.5 = nominal 6 in board)", "Gap between boards (in)", "Board length"; results are recalculated instantly as you type.

面板数量怎么算？How are the boards counted?

排数 = 甲板宽度 ÷ (板宽 + 板缝)，向上取整；总长度 = 排数 × 甲板长度；每排需要 ⌈甲板长度 ÷ 板长⌉ 块板（一块板不能同时用在两排），块数 = 排数 × 每排块数 × (1 + 损耗率)，向上取整。注意用面板的实际宽度：名义 6 英寸的板实际约 5.5 英寸。Rows = deck width ÷ (board width + gap), rounded up; total length = rows × deck length; each row needs ⌈deck length ÷ board length⌉ boards (one board cannot serve two rows), so boards = rows × boards per row × (1 + waste), rounded up. Use the actual width: a nominal 6 in board is about 5.5 in.

龙骨和螺钉怎么算？How are joists and screws counted?

龙骨垂直于面板，沿甲板长度按中到中间距排布：根数 = 长度 ÷ 间距（向上取整）+ 1，保证甲板两端都有龙骨。每块面板在每根龙骨处用 2 颗螺钉，螺钉数 = 排数 × 龙骨数 × 2。Joists run across the boards, spaced along the deck length: joists = length ÷ spacing, rounded up, + 1, so both ends of the deck have a joist. Each board gets 2 screws at every joist, so screws = rows × joists × 2.
