我國移動腳手架的材料劃分方法

我國移動腳手架的材料劃分方法1）梯式腳手架單一規格鋼管的腳手架。它隻使用一種規格的鋼管，如扣件式鋼管腳手架，隻使用Ф48×3.5的電焊鋼管。2）門式腳手架多種規格鋼管組合的移動腳手架。它由兩種以上的不同規格的鋼管構成，如門式腳手架。3）移動腳手架以鋼管為主的移動腳手架。即以鋼管為主，並輔以其它型鋼桿件所構成的門式腳手架，如設有槽鋼頂托或底座的裡門式腳手架，有連接鋼板的挑梯形腳手架等。
China's mobile scaffolding material division method 1) ladder scaffold single specification steel pipe scaffold. It only uses one kind of steel pipe, such as fastener type steel pipe scaffold, and only uses 48 x 3.5 welded steel pipe. 2) scaffolding of various kinds of steel pipe scaffolds with portal type scaffolds. It consists of two or more kinds of steel pipes, such as portal scaffolds. 3) mobile scaffold with steel pipe as the main scaffold. That is to say, scaffolding consisting mainly of steel pipes and supplemented by other steel members, such as inner scaffolding with channel steel top bracket or base, and lifting scaffolding with connecting steel plates, etc.
移動腳手架按垂直力分類
Classification of mobile scaffolds by vertical forces
（1）靠接觸面摩擦作用傳力。即靠節點處的接觸面壓緊後的摩擦反力來支承橫桿荷載並將其傳給立桿，如扣件的作用，通過上緊螺栓的正壓力產生摩彩色沥清地坪擦力；
(1) force transfer by contact surface friction. That is to say, the load of the cross bar is supported by the friction reaction after th环氧地坪e contact surface of the joint is compressed and transmitted to the vertical bar, such as the role of the fastener, which generates friction through the positive pressure of the tightening bolt.
（2）靠焊縫傳力。大多數橫桿與立桿的承插聯結就是采用這種方式，門架也屬於這種方式；
(2) transfer force by welding seam. Most of the crossbar and vertical pole socket connection is in this way, the portal frame also belongs to this way.
（3）直接承壓傳力。這種方式多見於橫桿擱置在立桿頂端的裡梯形腳手架；
(3) direct pressure transmission. This method is commonly seen in the scaffolding resting on the top of the vertical pole.
（4）靠銷桿抗剪傳力。即用銷桿穿過橫桿的立式聯結板和立桿的孔洞實現聯結、銷桿雙面受剪力作用。
(4) the shear force of the pin. That is to say, the pin rod is connected through the vertical connecting plate of the cross bar and the hole of the vertical bar, and the pin rod is subjected to shear force on both sides.
在立桿與立桿的聯結中，也有3種傳力方式：
There are 3 ways of transferring force between the vertical pole and the upright bar.
（1）承插對接的支承傳力。即上下立桿對接，采用連接棒或承插管來確保對接的良好狀態；
(1) bearing transfer force. That is to connect the upper and lower poles, and use connecting rods or socket pipes to ensure a good state of docking.
（2）銷桿連接的銷桿抗剪傳力；
(2) the shear force of pin rod connected with pin;
（3）螺扣連接的嚙合傳力。即內管的外螺紋與外（套）管的內螺紋嚙合傳力。其中後兩種傳力方式多用於調節高度要求的立桿連接中。
(3) the meshing force of the screw connection. That is, the outer thread of the inner tube is engaged with the internal thread of the outer sleeve. The latter two ways of transmission are mostly used to adjust the vertical bar connection with high requirements.
移動腳手架按固著方式
Mobile scaffolds are fixed.
（1）定距連接：即聯結焊件在桿件上的定距設置，桿件長度定型，聯結點間距定型；
(1) Fixed-pitch connection: that is, the fixed-pitch setting of the connecting weld on the rod, the fixed-pitch setting of the rod length and the fixed-pitch setting of the connecting point;
（2）不定距聯結：即聯結件為單設件，通過上緊螺栓可夾持在桿件的任何部位上。
(2) Uncertain distance connection: that is, the connecting part is a single unit, which can be clamped on any part of the rod through the tightening bolt.
按作業方式
By way of operation
（1）插入打緊；
(1) insert tight;
（2）擰緊螺栓。
(2) tighten bolts.
