What is a scaffold anti-slip buckle?

Scaffold anti-slip buckle is a fastener on fastener-type steel pipe scaffold, which is a fastening connector fastened with bolts. Fasteners are divided into right-angle fasteners (cross fasteners and directional fasteners), rotary fasteners (movable fasteners and universal fasteners) and butt fasteners (straight fasteners and direct fasteners).

Fastener-type steel pipe scaffold refers to the scaffold and supporting frame which are erected for building construction and bear load, and are composed of fasteners and steel pipes, collectively referred to as scaffolding.

The fastener-type steel pipe scaffold commonly used in China is made of cast iron, and its mechanical properties should comply with steel tube scaffold couplers Steel Pipe Scaffolding (GB 1583 1-2006), and the material should not be lower than KT330-08. It is also required that the fastener-type steel pipe scaffold system has fewer parts, simple installation and easy disassembly.

Advantages and disadvantages of fastener scaffold:

1, advantages

1) has a large bearing capacity. When the geometry size and structure of the scaffold meet the relevant requirements of the code, in general, the bearing capacity of the scaffold single column can reach15kn ~ 35kn (1.5tf ~ 3.5tf, the design value).

2) Convenient disassembly and assembly and flexible erection. Because the length of steel pipe is easy to adjust and the fastener connection is simple, it can be used for scaffolding of buildings and structures in various planes and facades.

3) economy, simple processing and low one-time investment cost; If the geometric dimensions of scaffolding are carefully designed and the turnover rate of steel pipes is improved, the material consumption can also achieve better economic results. Fastener steel pipe frame is equivalent to about 15 kg of building steel per square meter.

2. Deficiencies

1) fasteners (especially its screws) are easy to lose;

The torque for tightening bolts should not be less than 40N·m and not more than 65 N m;

2) The members at the joint are eccentrically connected, and the load and internal force are transferred by the anti-sliding force, which reduces its bearing capacity;

3) The connection quality of fastener nodes is significantly influenced by the quality of fasteners themselves and the operation of workers.
