The product is highly economical and more convenient and faster to use: During use, you only need to insert the plugs at both ends of the horizontal bar into the corresponding tapered holes on the vertical bar, and then tap it tightly. However, the speed of assembly and disassembly and the quality of overlap cannot be achieved by traditional scaffolding. Its erection and disassembly speed is 4-8 times that of fastener steel pipe scaffolding, and more than 2 times that of bowl-buckle type scaffolding. Reduce labor time and labor remuneration, reduce freight and reduce overall costs. The joint structure is reasonable, easy to operate, lightweight and convenient. The weight of the pole is 6-9% less than that of a bowl-buckle pole of the same length.
4. Large carrying capacity. The vertical pole transmits force axially, making the scaffold as a whole in three-dimensional space, with high structural strength and good overall stability. The disc has reliable axial shear resistance, and the axes of various poles intersect at one point, and the number of connecting crossbars is larger than that of the bowl. There are twice as many buckle joints, and the overall stable strength is increased by 20% due to bowl buckles and scaffolding.
5. Safe and reliable. An independent wedge is used to penetrate the self-locking mechanism. Due to interlocking and gravity, the crossbar plug cannot come out even if the latch is not knocked tightly. The plug-in has a self-locking function. You can press the latch to lock or pull it out for disassembly. In addition, the contact surface between the fastener and the pillar is large, which improves the bending strength of the steel pipe and ensures that when the two are combined, the pillar will not Skewing will occur.
The roulette type multifunctional steel pipe scaffolding has high vertical intersection accuracy between the axis of the vertical pole and the axis of the crossbar, and the force properties are reasonable. Therefore, the bearing capacity is large, the overall rigidity is large, and the overall stability is strong. Each vertical pole is allowed to carry 3-4 tons. The number of inclined tie rods used is much less than that of traditional scaffolding.
6. Good overall benefits. The component series is standardized to facilitate transportation and management. There are no scattered and easily lost components, low loss, and low later investment.
When installing, you only need to align the crossbar joint with the position of the daisy disk, then insert the latch into the hole of the daisy disk and through the bottom of the joint with your hand, and then tap the top of the latch with a hammer to make the crossbar joint on The arc surface is closely integrated with the vertical pole.
Bowl-button type scaffolding
