1. Comparison between coupler steel pipe scaffold and new scaffold
Fastener steel pipe scaffold in bridge municipal engineering, industrial construction engineering and the inner frame full of red frame support mold performance, its bearing capacity is large and safe and efficient. Compared with ordinary steel pipe fasteners, its dismantling speed is increased by 2-4 times.
Ringlock scaffold is mainly suitable for civil construction projects, building internal frame support mold and full room rack support. Its dismantling speed is amazing, which can reach 8-10 times that of ordinary steel pipe fasteners, and even 2-4 times faster than ringlock scaffolding. However, ordinary steel pipe fasteners are mainly used for outer frame skew bracing.
However, it is worth noting that there are shortcomings in construction efficiency, labor intensity and safety, and its use is gradually decreasing. Today, it is more regarded as auxiliary scaffolding, mainly used for irregular parts of the tower installation and connection.
2. H Frame scaffolding
The frame scaffold is constructed with standard H frame, scissor brace and its related components. It is mainly used for the construction of external scaffolding, and in the construction of scaffolding in the tower, if the length of the building wall is not an integer multiple of the standard distance between the door frame, it is usually impossible to use scissors to support, at this time, it is necessary to use the scaffolding steel pipe as a horizontal pipe and inclined pipe to strengthen.
The ladder frame design of the frame scaffold gives it excellent load-bearing capacity and stability, while the shelf ladder also provides convenient access for personnel. In addition, the trapezoidal frame can also be flexibly used as a template bracket, an active platform, etc., with various functions. Frame scaffolding can not only be used for tower full scaffolding, but also for building temporary stands and viewing platforms. The height of the tower is generally limited to 45 meters, but with appropriate measures, the height can be raised to 60-70 meters.
3.Cuplock scaffold
Cuplock scaffolding is divided into light, ordinary and heavy three categories. Lightweight bowl buckle scaffolding is mainly suitable for decoration projects, while ordinary cuplock scaffolding can be used for decoration, masonry and as a formwork support frame. For large loads, heavy cuplock scaffolding is more suitable.
This kind of scaffold is combined with 0.3 meter long transverse rod, vertical rod and top rod to form a stable support column. The basic dimensions of these support columns are 0.3 m x 0.3 m x 0.6 m, and the height can be flexibly combined. The column head and column foot are respectively equipped with adjustable seat and cushion seat (or corner seat), so that the lattice composite steel column can be used alone or in group combination. This design gives the cuplock scaffold a significant advantage when used as a rigid structural member.
Compared with the frame scaffold, the cuplock scaffold is excellent in load-bearing, and the derrick and platform set up by the tower are more stable and reliable than the frame scaffold.
4.Aluminum scaffolding tower
Tower scaffold can play its unique role in many occasions because of its few parts, compact frame, convenient assembly and disassembly and strong bearing capacity. Through the complementary docking of the two triangle frames, a rectangular frame can be easily formed, and the standard frame of the square tower scaffold itself presents a rectangular shape. These two kinds of tower scaffolding can be used for tower internal and external scaffolding to meet different construction needs. In addition, through the tower group method, multiple tower scaffolds can be flexibly combined to build an operating platform or a full scaffold to further expand its scope of use.
Tower scaffold has excellent performance in formwork support, especially suitable for Bridges, water conservancy and hydropower projects with large forces formwork support. The triangular frame unit can bear up to 15t, and the bearing capacity of the square tower scaffold unit tower is up to 18t, ensuring stability and safety in the construction process.
From the above comprehensive comparative analysis, we can look forward to the future development trend of scaffolding. With the advancement of science and technology and the improvement of environmental protection requirements, scaffolding will gradually evolve into a lightweight, high-strength, standardized, assembled and multi-functional direction. At the same time, the establishment of a professional scaffolding contracting company will also become an important direction for the development of the industry. In terms of materials, traditional materials such as wood and bamboo will be replaced by metal products; In the construction process, more efficient assembly methods will be gradually adopted, and the use of cumbersome parts such as fasteners and bolts will be reduced or completely abandoned. In addition, the material will gradually turn to lightweight high-strength materials such as thin-wall steel and aluminum alloy products to meet the development needs of the future construction field.
