Bowl-lock Scaffolding: Bowl-lock scaffolding is a new type of socket-type steel pipe scaffolding. It features a unique toothed bowl-lock joint, offering rapid assembly and disassembly, labor-saving construction, stable and reliable structure, comprehensive equipment, strong versatility, high load-bearing capacity, safety, ease of processing, low risk of loss, convenient management, easy transportation, and wide application, significantly improving work efficiency. It has received numerous international and domestic awards and was one of the ten key new technologies promoted by the Ministry of Construction before 2000.
Advantages of Bowl-lock Scaffolding:
1. Multifunctionality: This construction equipment can be assembled into single-layer or double-layer scaffolding, support frames, support columns, material lifting frames, climbing scaffolding, cantilever frames, and other equipment of different shapes, sizes, and load-bearing capacities according to different construction needs. Furthermore, this equipment can also be used to construct construction sheds, warehouse sheds, lighthouses, and other building structures. It is particularly suitable for constructing curved scaffolding and supports with high load-bearing capacity.
2. Efficiency: The longest commonly used member is 3130mm, weighing 17.07KG. The assembly and disassembly speed is 3-5 times faster than conventional methods, requiring less effort. Workers can complete all work with just a hammer, avoiding the inconvenience of bolt operations.
3. High Versatility: The main components use ordinary coupler-type steel pipe scaffolding pipes, which can be connected to ordinary steel pipes using couplers, offering high versatility.
4. High Load-Bearing Capacity: The uprights are connected by coaxial socket joints, and the horizontal members are connected to the uprights via cup-lock joints. These joints have reliable bending, shear, and torsional mechanical properties. Furthermore, the centerlines of all members intersect at a single point, and the nodes are within the frame plane; therefore, the structure is stable, reliable, and has a high load-bearing capacity. (The overall load-bearing capacity is increased by approximately 15% or more compared to equivalent coupler-type steel pipe scaffolding.)
5. Safe and Reliable: The joint design takes into account the spiral friction and self-weight of the upper cup coupler, giving the joint reliable self-locking capability. The load acting on the horizontal bar is transferred to the vertical bar through the lower cup coupler, which has strong shear resistance (maximum 199KN). Even if the upper cup coupler is not tightened, the horizontal bar joint will not come loose and cause an accident. It is also equipped with safety net supports, horizontal bars, footboards, toe boards, ladders, cantilever beams, wall ties, and other accessories, ensuring safe and reliable use.
6. The main components use Φ48×3.5, Q235 welded steel pipes, with a simple manufacturing process and moderate cost. Existing coupler-type scaffolding can be directly modified without complex processing equipment.
7. Less Prone to Loss: This scaffolding has no loose, easily lost couplers, minimizing component loss.
8. Minimal Maintenance: This scaffolding structure eliminates bolt connections. The components are impact-resistant and durable. General rust does not affect assembly and disassembly operations, requiring no special maintenance or repair.
9. Easy Management: The components are standardized and painted orange, resulting in an aesthetically pleasing appearance. Components are neatly stacked, facilitating on-site material management and meeting the requirements of civilized construction. 10. Transportation: The longest component of this scaffolding is 3130mm, and the heaviest component weighs 40.53kg, making it easy to handle and transport.
Ringlock Scaffolding: Ringlock (direct-insertion) scaffolding is a new type of direct-insertion steel pipe scaffolding with a self-locking function. It is manufactured in accordance with the “Safety Technical Standard for Socket-Type Ringlock Steel Pipe Scaffolding in Building Construction” JGJ/T 231-2021 issued by the Ministry of Housing and Urban-Rural Development. The main components are uprights and horizontal bars. The ringlock node structure is reasonable, and the uprights transmit force axially, resulting in high overall structural strength and stability in three-dimensional space. It also has a reliable self-locking function, effectively improving the overall stability and safety of the scaffolding, and better meeting the needs of construction safety. It features rapid assembly and disassembly, labor-saving construction, simple and reliable structure, strong versatility, high load-bearing capacity, safety and efficiency, low risk of loss, easy management, and easy transportation.
Advantages of ringlock scaffolding:
1. Reliable two-way self-locking capability: Firstly, the locking function of the horizontal and vertical members at the connecting plates is mainly achieved and guaranteed by the structural design, reducing the disadvantages of manual locking in traditional scaffolding and minimizing the instability factor of personnel. Secondly, at the same node, the connection and locking method of multiple horizontal members to the same vertical member changes from the traditional interlocking type to an independent, non-interfering self-locking type. In traditional scaffolding, if the locking of one horizontal member at the same node becomes loose, the locking of other horizontal members to the vertical members will also be compromised.
2. Excellent Economy and Overall Performance: With no movable parts, it consists only of uprights and horizontal bars, all manufactured in the factory. This minimizes the risk of loss or damage to movable parts common in traditional scaffolding, reducing economic losses for construction companies. Furthermore, the absence of movable locking devices ensures a reasonable distribution of tension and pressure at each node, guaranteeing excellent rigidity and overall stability, and minimizing the safety hazards associated with movable locking devices in traditional scaffolding.
3. Easier and Faster Installation: Installation is simple. Just insert the plugs at both ends of the horizontal bar into the corresponding conical holes on the upright and tighten. The speed and quality of assembly and disassembly are unmatched by traditional scaffolding. Its assembly and disassembly speed is 8-10 times that of coupler-type scaffolding and more than twice that of cup-lock scaffolding.
4. High Load-Bearing Capacity: The vertical intersection accuracy of the upright and horizontal axis lines of the ring-lock multi-functional steel pipe scaffolding is high, and the stress distribution is reasonable. Therefore, it has a high load-bearing capacity, high overall rigidity, and strong overall stability. Each upright can bear 3-4 tons. Furthermore, the number of diagonal braces used is significantly less than that of traditional scaffolding.
5. Multifunctionality: The ring-lock multi-functional steel pipe scaffolding can be used with adjustable lower supports, adjustable upper supports, double adjustable early dismantling mechanisms, cantilever beams, cantilever frames, and other accessories. It can be used in conjunction with various types of steel pipe scaffolding to achieve various multifunctionalities.
Disc-Lock Scaffolding: Disc-lock scaffolding is a new type of scaffolding. This product was introduced from Europe in the 1980s and is an upgraded replacement for cup-lock scaffolding. Also known as the chrysanthemum disc scaffolding system, insert disc scaffolding system, wheel disc scaffolding system, snap-on disc scaffolding, Layher scaffolding (layer scaffolding, Layher scaffolding, because its basic principle was invented by the German company LAYHER, it is also called “Layher scaffolding” in the industry). It is mainly used for lighting, scaffolding, and backdrop scaffolding in large concerts. The disc-type multi-functional scaffolding is an upgraded product following the cup-lock scaffolding. The socket of this scaffolding is a 133mm diameter, 10mm thick disc with 8 holes. It uses φ48*3.5mm, Q345B steel pipe as the main component. The uprights are made by welding a disc every 0.60m along a certain length of steel pipe. These novel and aesthetically pleasing discs connect the horizontal bars with connecting sleeves at the bottom. The horizontal bars are made by welding plugs with pins to both ends of the steel pipe.
Advantages of disc-lock scaffolding:
1. Reliable two-way self-locking capability;
2. No moving parts;
3. Convenient and quick transportation, storage, erection, and dismantling;
4. Reasonable load-bearing performance;
5. Freely adjustable;
6. Standardized product packaging;
7. Reasonable assembly; its safety and stability are better than cup-lock scaffolding and superior to frame scaffolding.
Coupled-type steel pipe scaffolding: Coupled-type steel pipe scaffolding refers to scaffolding and support frames constructed of couplers and steel pipes, erected for construction work and bearing loads. Couplers are fastened with bolts.
Advantages of coupled-type steel pipe scaffolding:
1) High load-bearing capacity. When the geometric dimensions and structure of the scaffolding meet the relevant requirements of the specifications, the load-bearing capacity of a single pipe column of the scaffolding can generally reach 15kN～35kN (1.5tf～3.5tf, design value).
2) Convenient assembly and dismantling, flexible erection. Because the length of the steel pipes is easily adjustable and the fastener connections are simple, it can be adapted to scaffolding for various planar and vertical buildings and structures.
3) Relatively economical. Processing is simple, and the initial investment cost is low. If the scaffolding geometry is carefully designed and attention is paid to improving the turnover rate of steel pipes, good economic results can be achieved in terms of material usage. The steel pipe scaffolding with fasteners uses approximately 15 kg of steel per square meter of building area.
