The portal scaffold is a standardized steel pipe scaffold composed of portal frame, cross support, connecting rod, buckle scaffold board or horizontal frame, lock arm, etc., and then equipped with horizontal reinforcing rod, cross bracing, sweeping rod, sealing rod, bracket and base, and connected with the main structure of the building by wall connecting parts. Portal steel pipe scaffold can be used not only as external scaffold, but also as internal scaffold or full scaffold.

purpose

1. It is used for supporting the roof in the formwork of buildings, halls, bridges, viaducts and tunnels or as the main frame of flying formwork support.

2. Make internal and external grid scaffolds for high-rise buildings.

3. Movable working platform for electromechanical installation, hull repair and other decoration works.

4. The temporary site dormitory, warehouse or work shed can be formed by using portal scaffold and simple roof truss.

5. It is used to set up temporary auditorium and grandstand

Fastener scaffold has the characteristics of flexible disassembly, convenient transportation and strong universality. Therefore, it is widely used in China. In scaffold engineering, its use accounts for more than 60%. It is the most widely used and widely used scaffold at present. However, this kind of scaffold has poor safety assurance and low construction efficiency, and can not meet the needs of the development of capital construction projects.

There are many specifications and sizes of main components

There are many specifications and sizes of portal scaffolds all over the world, including international units and British units of measurement. For example, the width of 1219 portal frame in English unit is 4 ‘(1219mm) and the height is 6′ (1930mm), and the width of 1219 portal frame in international unit is 1200 mm and the height is 1900 mm. The gantry width of foreign scaffold companies mainly includes 900, 914, 1200 and 1219 mm. There are many dimensions of gantry height, forming a set of system.

The product specifications of several manufacturers in China are also very inconsistent. Some imitate foreign product specifications, and some domestic research units design a set of system by themselves. Some adopt British size and some adopt international unit size. For example, the width of the gantry is 1219mm in English system, 1200mm in international system of units, and the frame spacing is 1829mm and 1830mm respectively. Due to these different dimensions, the gantry cannot be used for each other. As another example, there are more than eight height specifications and sizes of the gantry, and there are also many spacing sizes between the connecting pins, resulting in many specifications and varieties of cross diagonal bracing.

It is precisely because of the wide range of sizes that we need powerful enterprises like us to meet various requirements of customers. Welcome to inquire, please email us for details.
