The models of disc-buckle scaffolding are mainly divided into two types: A-type and B-type according to the safety technical regulations JGJ231-2010 for the construction of socket-type disc-buckle steel pipe brackets. Type A: It is the 60 series that is often said in the market, that is to say, the pole diameter is 60mm, which is mainly used for heavy supports, such as bridge engineering. Type B: It is the 48 series, the pole diameter is 48mm, which is mainly used in housing construction and decoration, stage lighting racks and other fields. In addition, according to the connection mode of the disc-buckle scaffolding pole, it is divided into two forms: outer sleeve connection and inner connecting rod connection. At present, the 60 series disc buckle scaffolding on the market generally adopts internal connection, that is, the connecting rod is connected inside the vertical pole. The 48 series disc buckle scaffolds are generally connected by outer sleeves, and some are connected by inner connecting rods, especially in the fields of stage racks and lighting racks. The main components of the disc buckle scaffold are: vertical pole, horizontal pole, inclined pole, adjustable top and bottom support. The distance between the discs is 500mm.
The specification modulus of the disc buckle pole is 500mm, the specific commonly used specifications are 500mm, 1000mm, 1500mm, 2000mm, 2500mm, 3000mm, and the base is 200mm.
The model specification modulus of the disc buckle horizontal rod is 300mm. Namely 300mm, 600mm, 900mm, 1200mm, 1500mm, 1800mm, 2400mm. Note: The nominal length of a horizontal rod is the distance between the axis of the vertical rod, so the actual length is shorter than the nominal length by the diameter of the vertical rod. According to the nature of the project, the general formwork supports the scaffold, and the largest amount is 1.5m horizontal rods, 1.2m and 1.8m, etc., used in conjunction. For the operating frame, the length of the horizontal rod is generally 1.8m, and 1.5m, 2.4m, etc. are used in conjunction.
The specifications of the vertical diagonal bar of the disc buckle are divided according to the length and step distance of the horizontal bar. Generally, the step distance of the horizontal bar supported by the template is 1.5m, so the vertical diagonal bar supported by the template is generally 1.5m in height. Example: The vertical diagonal rod with a 900m horizontal rod is 900mmX1500mm. In actual projects, the most commonly used vertical diagonal rods for formwork support frames are 1500mmX1500mm, 1800mmX15mm, and the most commonly used for ordinary scaffolding projects are 1800mmX1500mm or 1800mmX2000mm.
