门式脚手架是一种工厂生产、现场搭设的移动脚手架,是当今国际上应用最普遍的脚手架之一。它不仅可作为外脚手架,也可作为内脚手架或满堂移动脚手架门式钢管脚手架因其几何尺寸标准化、结构合理、受力性能好、施工中装拆容易、安全可靠、经济实用等特点,广泛应用于建筑、桥梁、隧道、地铁等工程施工,若在门架下部安放轮子,也可以作为机电安装、油漆粉刷、设备维修、广告制作的活动工作平台。

Portal scaffolding is a kind of scaffolding built in factories. It is one of the most widely used scaffolding in the world today. It can not only be used as an external scaffold, but also as an internal scaffolding or full scaffolding. Portal steel tubular scaffolding is widely used in construction of buildings, bridges, tunnels and metros because of its standardized geometry, reasonable structure, good mechanical performance, easy installation and disassembly, safety, reliability, economy and practicability. If wheels are placed under the portal scaffolding, it can also be used as mechanical and electrical installation, painting and equipment. Maintenance, advertising production activities platform.

门式钢管脚手架的搭设一般只要根据产品目录所列的使用荷载和搭设规定进行施工,不必再进行验算。如果实际使用情况与规定有不同,则应采用相应的加固措施或进行验算。通常门式钢管移动脚手架搭设高度限制在45m以内,采取一定措施后可达到80m左右。施工荷载取值一般为:均布荷载1.8kN/㎡,或作用于脚手板跨中的集中荷载2kN.

The erection of portal steel tubular scaffolding generally needs only construction according to the service load and erection stipulations listed in the product catalogue, and no checking calculation is needed. If the actual usage is different from the regulations, corresponding reinforcement measures or checking computations should be adopted. Generally, the erection height of portal steel tube scaffolding is limited to 45 m, and it can reach about 80 m after taking certain measures. The values of construction load are generally: 1.8kN/ of uniform load, or the concentrated load acting on the span of the scaffold plate 2kN.

门式钢管门式脚手架是用普通钢管材料制成工具式标准件,在施工现场组合而成。其基本单元是由一副门式框架、二副剪刀撑、一副水平梁架和四个连接器组合而成。若干基本单元通过连接器在竖向叠加,扣上臂扣,组成一个多层框架。在水平方向,用加固杆和水平梁架使相邻单元连成整体,加上斜梯、栏杆柱和横杆组成上下步相通的外门式脚手架

Portal steel pipe scaffolding is a tool-type standard component made of common steel pipe material, which is assembled in the construction site. Its basic unit is composed of a portal frame, two pairs of scissors, a pair of horizontal beam frame and four connectors. Several basic units are vertically stacked through the connector and buckle up the arms to form a multi-storey frame. In the horizontal direction, the adjacent elements are connected into a whole by the reinforcement bar and the horizontal beam frame, and the outer scaffolding connected with the upper and lower steps is composed of inclined ladder, balustrade column and cross bar.
