Ministry of Housing and Urban-Rural Development issued the Catalogue of Prohibited and Restricted Technologies for Housing Construction and Municipal Infrastructure Projects (the second batch), which will be implemented after August 28, 2025. The second batch of catalogues will eliminate 23 construction technologies, equipment and materials. The first and second batches add up to 45 items being eliminated, and the third batch is still being collected. It is mentioned
in the second batch that
the wheel-buckle scaffold shall not be used as the supporting scaffold for the divisional and subdivisional works with greater danger. Replace it
with socket and spigot type plate and buckle type scaffold.
Disc vs Wheel
Plate buckle frame is the recommended process of new technology in the construction industry, and wheel buckle frame has been gradually eliminated by the market. The plate buckle frame with
two
different
shapes: the vertical pole is used to receive the faceplate with 8 holes, 4 of which are equipped with diagonal bracing, and the hot-dip galvanized process surface layer.
Wheel buckle frame: there are 4 holes for the vertical pole to receive the faceplate, and there is no diagonal bracing hole position, and the surface layer is painted. The shapes of the
plate buckle frame and the wheel buckle frame are basically the same, and the biggest difference between them is the position of the receiving plate. The plate buckle scaffold has 8 holes, and the wheel buckle scaffold has 4 holes. The second is the surface process, the plate buckle scaffold is hot galvanized, the wheel buckle scaffold is painted, which needs to be renovated after a period of use, and the plate buckle scaffold is more beautiful in appearance. The
three
components are different
: the components of the plate-buckle scaffold are all made of low-alloy structural steel (national standard Q3 45B).
Wheel buckle frame: the components of the wheel buckle scaffold are generally made of carbon steel (national standard Q235). The material strength of the
disk buckle frame is the strength of the wheel buckle frame. 1.
The four
differences are the different
structural modes of the disk buckle frame: the node connection mode adopts the bolt connection mode, with its own diagonal brace, and the shape is perfect.
Wheel buckle frame: the node connection mode is coaxial socket, and the node is connected in the plane of the frame. The design features of
the plate buckle frame are more advanced, so that the force transmission of each rod can pass through the center of the node, and the use is safer. The fifth
difference is that the application scope is different
: with stable system and high load-bearing performance, it can be widely used in outdoor high formwork, high load-bearing structural support system and indoor support frame.
Wheel buckle frame: generally, the wheel buckle frame is only applicable to the low-rise indoor support formwork. Because of its structure, the
wheel buckle frame is mostly used for indoor support of housing construction projects; because of its own diagonal rod, the disk buckle frame has better stability and unlimited scope of application.
The Ministry of Housing and Urban-Rural Development has published two batches of prohibited and restricted catalogues, and this article is a summary of the two batches of prohibited and restricted catalogues:
In November 2024, the official website of the Ministry of Housing and Urban-Rural Development published the Catalogue of Prohibited and Restricted Technologies for Housing Construction and Municipal Infrastructure Projects (the second batch), which will be implemented after August 28, 2025. The second batch of catalogues eliminated 23 items of construction technology, equipment and materials. In December
2021, the Ministry of Housing and Urban-Rural Development issued the Catalogue of Construction Processes, Equipment and Materials for Housing Construction and Municipal Infrastructure Projects that Endanger Production Safety (the first batch), which has been formally implemented. The first batch of catalogues has eliminated 22 construction processes, equipment and materials.
The second batch: a total of 23 construction processes were eliminated. Equipment and materials
Prohibit the use of technology (9 items)
Steel bar "hot bending" processing technology
Stone and porcelain plate backward hanging technology
Manual hanging basket (on-site assembly)
Three-point safety belt
