      門式腳手架大无限彩票开户是修建用腳手架中,使用最廣的腳手架之一。因為主架呈“門”字型,所以稱為門式或門型腳手架,也稱鷹架或龍門架。這種腳手架主要由主框、橫框、穿插斜撐、腳手板、可調底座等構成。

    銜接構建方面,門架的各種銜接扣件螺栓擰緊扭力矩在40~65 N·m之間,以防構件不能有用承力或被損壞,搭設完結后用扳手隨機抽樣檢查,不合格的有必要重新擰緊,直至合格停止。不允許短少銜接構件或螺栓擰而不緊或在裝置后隨意拆開,使門式腳手架發作變形而受到損壞。支持立桿要筆直,縱橫向水平桿要平坦。立桿應盡量選用通長鋼管,如需接收,接頭要錯開,不在同一步距內,立桿口有必要按標準對接,確保架體筆直度。相鄰的兩根縱向水平桿的接頭要相互交織,接駁口有必要按標準對接。
