(1)梯式脚手架单一规格钢管的脚手架。它只使用一种规格的钢管,如扣件式钢管脚手架,只使用Ф48×3.5的电焊钢管。2)门式脚手架多种规格钢管组合的脚手架。它由两种以上的不同规格的钢管构成,如门式脚手架。3)移动脚手架以钢管为主的脚手架。即以钢管为主,并辅以其它型钢杆件所构成的脚手架,如设有槽钢顶托或底座的里脚手架,有连接钢板的挑脚手架等。

(1) scaffolding of ladder type scaffold with single specification steel pipe. It uses only one type of steel pipe, such as fastener scaffolding, and only_48 *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 shaped steel rods, such as inner scaffolding with trough steel top bracket or base, scaffolding connected with steel plates, etc.

按垂直力

According to the vertical force

(1)靠接触面摩擦作用传力。即靠节点处的接触面压紧后的摩擦反力来支承横杆荷载并将其传给立杆,如扣件的作用,通过上紧螺栓的正压力产生摩擦力;

(1) force transfer by contact surface friction. That is to say, the cross bar load is supported by the friction reaction after the contact surface at the node is pressed and transmitted to the vertical bar, such as the effect of fastener, and the friction is produced by the positive pressure of the upper tightening bolt.

(2)靠焊缝传力。大多数横杆与立杆的承插联结就是采用这种方式,门架也属于这种方式;

(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)直接承压传力。这种方式多见于横杆搁置在立杆顶端的里脚手架;

(3) direct pressure transmission. This method is commonly seen in the scaffolding resting on the top of the vertical pole.

(4)靠销杆抗剪传力。即用销杆穿过横杆的立式联结板和立杆的孔洞实现联结、销杆双面受剪力作用。

(4) the shear force of the pin. That is to say, the pin rod passes through the holes of the vertical connecting plate and the vertical rod to realize the connection and the pin rod is subjected to the shear force on both sides.

在立杆与立杆的联结中,也有3种传力方式:

There are 3 ways of transferring force between the vertical pole and the upright bar.

(1)承插对接的支承传力。即上下立杆对接,采用连接棒或承插管来确保对接的良好状态;

(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)销杆连接的销杆抗剪传力;

(2) the shear force of pin rod connected with pin;

(3)螺扣连接的啮合传力。即内管的外螺纹与外(套)管的内螺纹啮合传力。其中后两种传力方式多用于调节高度要求的立杆连接中。

(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.

按固着方式

Fixing mode

(1)定距连接:即联结焊件在杆件上的定距设置,杆件长度定型,联结点间距定型;

(1) Fixed-distance connection: that is, the fixed-distance setting of the connecting weldments on the rods, the length of the rods and the spacing of the connecting points;

(2)不定距联结:即联结件为单设件,通过上紧螺栓可夹持在杆件的任何部位上。

(2) indeterminate spacing connection: that is, the connecting piece is a single unit, which can be clamped on any part of the rod by means of the upper tightening bolt.

按作业方式

By way of operation

(1)插入打紧;

(1) insert tight;

(2)拧紧螺栓。

(2) tighten bolts.
