The bowl-type scaffolding is a new type of socket-type scaffolding. Compared with the traditional fastener-type steel scaffolding, it has great advantages in use. It is very convenient and quick to install and disassemble, and the safety of colleagues is slightly higher. . So what are the methods and scope of use of bowl-type scaffolding? The following small series will introduce you to:
1. Main technical content
The poles and crossbars of the bowl-type scaffolding are fixed length rod fittings made of medium-sized φ48×3.5 welded pipes, and the horizontal rods and the poles are connected by a unique bowl-and-buckle joint. The lower bowl buckle accepts the crossbar plug, the upper bowl buckle locks the crossbar plug; the basic size of the bowl buckle scaffold is set to the fixed modulus dimension, the step height is 600mm, and the vertical and horizontal column spacing is 300mm. Modular number; bowl-type scaffolding is generally used with a variety of auxiliary parts such as adjustable pole base, adjustable screw and wall support.
2. Technical indicators
There is currently no corresponding safety technical specification for bowl-type scaffolding to allow the design of the frame by the load method. When applying, refer to the "Construction Scaffolding Handbook" of China Construction Industry Press to compile the mobile scaffolding plan; the bowl-button scaffolding is used to check the allowable load of the pole to determine the erection size. When the step is 600mm, the allowable load of the pole is 4OkN/root; when the step is 1200mm, it is allowed to be 30kN/root; when the step is 1800mm, it is allowed to be 25kN/root; when the step is 2400mm, it is allowed to be 20kN/ root.
3. Scope of application
The bowl-type scaffolding currently has a certain amount of use in the highway and railway construction departments. Through promotion, the housing and municipal construction departments gradually replace 30% of the fastener-type steel pipe scaffolding, changing the situation of using single fastener-type steel pipe scaffolding in the past; For the external scaffolding with a height of 50m or less. It is also suitable for use as a basic frame for segmented cantilever and climbing scaffolding. It is also used as a scaffolding in the middle; it is suitable for use as a formwork bearing bracket for building construction, municipal, and bridge concrete horizontal members.
The above is some of the technical content of the bowl-shaped scaffolding that Xiaobian has summarized for you. I hope to help you!
