Rapid scaffold connecting device and construction method thereof

Abstract

The invention relates to a rapid scaffold connecting device and a construction method thereof. The rapid scaffold connecting device comprises a stand column which is sleeved with a ring disc connected with the ends of a plurality of transverse rods, U-shaped ends clamped to the ring disc are fixedly connected to the ends of the transverse rods, and the U-shaped ends and the ring disc are fixedly connected through bolts A and nuts A; and the stand column is further sleeved with a positioning ring buckle located below the ring disc to limit gliding of the ring disc. The rapid scaffold connecting device is large in rigidity, high transverse rod transmitting loads can be borne, the eccentricity effect is avoided during stressing, the stress performance is good, safety is high, and the overall stability of a scaffold is greatly improved; and rapid mounting and demounting of the scaffold can be achieved, the construction speed is high, and needed manpower is less.

Description

technical field [0001] The invention relates to a quick-connecting device for scaffolding and a construction method thereof, belonging to the field of civil engineering. Background technique [0002] Scaffolding is mainly used in civil engineering construction sites. It is a variety of brackets erected to solve high-altitude operations, vertical and horizontal transportation, and can also provide assistance for the enclosure of building peripheral safety nets and high-altitude installation components. According to the different materials used, scaffolding can be divided into bamboo scaffolding, wooden scaffolding, steel pipe scaffolding, synthetic material scaffolding and so on. At present, fastener-type steel pipe scaffolding is the most used in my country, which has the advantages of convenient assembly and disassembly and low cost, but also has the disadvantages of eccentric force, poor stability, and low construction efficiency, which seriously affects the erection quali...

AI Technical Summary

Problems solved by technology

The horizontal bar transmits load and distributes internal force to the vertical bar through the grip force of the fastener, and the second-order effect produced by this eccentric force will also have an adverse effect on the bearing capacity and stability of the scaffold

At the same time, the node connection stiffness is related to the manufacturing quality of fasteners and the tightening torque during installation, which makes the stiffness of each node of the same scaffold more discrete, which reduces the safety.

[0003] In recent years, the bowl-buckle scaffolding with axial force transmission has gradually begun to be widely used, which solves the problem of eccentric force of the fastener-type scaffolding, but the cost of the bowl-buckle scaffolding is higher than that of the fastener type, and it needs to be pressed on the pole. Setting bowl buckle nodes at intervals makes the process more complicated and limits the size of the frame, which is also inconvenient

[0004] From the above, it can be seen that the eccentric force of the scaffolding pole leads to a decrease in stability, insufficient rigidity of the connection node with the crossbar, and the complexity of the process increases the cost of manufacturing and construction, which are the main problems of scaffolding at present.
