Truly energy-saving, environmental protection, economic and practical.
Workers can complete all operations with a hammer, avoiding many inconveniences caused by bolt operation; ③ Strong versatility: the main components adopt the steel pipe of the ordinary fastener type steel pipe scaffold, which can be connected with the ordinary steel pipe with fasteners, with strong versatility.
The load acting on the cross bar is transmitted to the vertical bar through the turnbuckle, which has a strong shear resistance (the maximum is 199kn).
Workers can complete all operations with a hammer.
The components are collision resistant.
④ Large bearing capacity: the connection of the vertical pole is coaxial socket, and the horizontal pole is connected with the vertical pole by the bowl buckle joint, which has reliable bending, shear and torsional mechanical properties.
The assembly and disassembly is fast and labor-saving.
Disadvantages: ① the horizontal bar is a shaped bar of several sizes, and the bowl buckle node on the vertical bar is set at a spacing of 0.6m, which limits the size of the frame ② the U-shaped connecting pin is easy to lose ③ the price is relatively expensive 2.0 wheel buckle scaffold wheel buckle (in-line) scaffold is a new type of in-line steel pipe scaffold with self-locking function, which is produced according to the standard jgj231-2010 “safety technical specification for socket and turnbuckle steel pipe support in construction” issued by the Ministry of housing and urban rural development, The main components are upright and cross bars.
⑥ The service life of the turnbuckle scaffold is much longer than that of the fastener scaffold, which can generally be used for more than 10 years, because the bolt connection is abandoned.
It has the characteristics of rapid assembly and disassembly, labor-saving, simple structure, stability and reliability, strong versatility, large bearing capacity, safety and efficiency, not easy to lose, easy to manage, easy to transport and so on.
Disc type multifunctional scaffold is an upgraded product after bowl buckle scaffold.
Eight holes are opened on the disc φ 48*3.5mm, Q345B steel pipe is used as the main component.
② Efficacy: the longest common rod is 3130mm and weighs 17.07kg.
The assembly and disassembly speed of the whole frame is 3 ~ 5 times faster than that of the conventional one.
At the same time, it is equipped with safety net support, cross bar, scaffold board, toe board and ladder erection.
Pole accessories such as cantilever beam and wall brace are safe and reliable to use.
⑤ The products are packaged in a standardized way, with less maintenance, fast loading and unloading, convenient transportation and easy storage.
A disc is welded on a certain length of steel pipe every 0.60m.
3.0 disc scaffold disc scaffold is a new type of scaffold, which was introduced from Europe in the 1980s.
⑦ It has the function of early removal: the crossbar can be removed in advance for turnover, saving materials, timbers and labor.
(the bearing capacity of the whole scaffold is increased, which is about 15% higher than that of the fastener type steel pipe scaffold in the same situation.) ⑤ safety and reliability: when designing the joint, the screw friction and self gravity of the upper bowl buckle are taken into account, so that the joint has a reliable self-locking ability.
It has won various international and domestic awards for several times, and is one of the ten key new technologies promoted by the Ministry of construction before 2000.
The structure of the buckle joint is reasonable.
It is also called chrysanthemum disc scaffold system, plug-in disc scaffold system, wheel disc scaffold system, buckle disc scaffold, layher frame (layer frame, Leia frame), because the basic principle of this scaffold was invented by layher company in Germany, and it is also called “Leia frame” by insiders.
It can also be used to erect construction sheds, material sheds, lighthouses and other structures.
③ With large bearing capacity: the vertical rod connection is coaxial socket, the node is in the frame plane, the joint has bending, shear and torsional mechanical properties, the structure is stable, and the bearing capacity is large.
It is especially suitable for setting up curved scaffold and heavy-duty support frame.
⑧ The practice shows that the stability and safety of the single span, multi span continuous beam and frame structure building formwork support system with a beam span of less than 15m and a clearance layer height of less than 12m are better than the bowl buckle scaffold and better than the gantry scaffold.
This novel and beautiful disc is used to connect the cross bar with a connecting sleeve at the bottom..
Even if they are rusted, they will not affect the use of assembly and disassembly.
Advantages of bowl buckle scaffold: ① multi function: according to the specific construction requirements, it can form single and double row scaffolds with different frame sizes, shapes and bearing capacities, support frames, support columns, material lifting frames, climbing scaffolds, cantilever frames and other multi-functional construction equipment.
It is mainly used for lighting frame and background frame of large-scale concerts.
④ Safety and reliability: the function of self gravity is taken into account in the design of the joint, so that the joint has a reliable two-way self-locking ability.
1.0 Bowl buckle scaffold bowl buckle scaffold is a new socket type steel pipe scaffold.
Characteristics of wheel buckle scaffold ① it is multifunctional: it can form single and double row scaffolds, support frames, support columns and other multi-functional construction equipment with different frame sizes, shapes and bearing capacities according to specific construction requirements.
The scaffold has created the toothed bowl buckle joint, which has the characteristics of rapid assembly and disassembly, labor-saving, stable and reliable structure, perfect equipment, strong versatility, large bearing capacity, safety and reliability, easy processing, not easy to lose, easy management, easy transportation, wide application and so on, greatly improving the work efficiency.
Even if the upper bowl buckle is not pressed, the cross bar joint will not come out and cause accidents.
Moreover, the axis line of each member intersects at one point, and the node is in the frame plane.
The assembly and disassembly speed of joints is more than 5 times that of conventional blocks, which is fast and labor-saving.
② It has high efficiency: simple structure, simple and fast disassembly and assembly, which completely avoids the loss of bolt operation and scattered fasteners.
The axial force transmission of the upright makes the scaffold in three-dimensional space have high structural strength and good overall stability, and has a reliable self-locking function, which can effectively improve the overall stability strength and safety of the scaffold, and better meet the needs of construction safety.
The socket of this scaffold is a disc with a diameter of 133mm and a thickness of 10mm.
It is an upgraded product after the bowl scaffold.
Therefore, the structure is stable and reliable, and the bearing capacity is large.
The load acting on the cross bar is transmitted to the vertical bar through the lower bowl buckle, which has a strong shear capacity (up to 199kn).
