Problems solved by technology

[0003] 1. The locking of the tube fasteners of the tube buckle scaffolding is carried by frictional force, which is easy to fall off and cause safety accidents. It has been eliminated in developed countries;
[0004] 2. The bearing capacity of portal scaffolding is small, and the overlapping height is limited; the bowl-buckle scaffolding is supported by short-distance horizontal bars at right angles and uses a large amount of steel, so the lateral bearing capacity is poor and it is easy to collapse in a large area;
[0005] 3. Due to the wedge-shaped flat pin, the self-locking failure of the wedge-shaped flat pin under the action of factors such as horizontal load, dynamic load, thermal expansion and contraction, etc., will cause the node to loosen, and the frame will shake and deform, and the frame cannot be guaranteed. Overall stability, there are serious security risks
[0006] 4. After the existing scaffolding is built, the overall structural strength is relatively weak, the scope of use is relatively single, and the safety protection for construction personnel is also weak, and tens of thousands of construction workers are injured and killed every year due to safety accidents of existing scaffolding;
[0007] 5. In addition, the common problem is that the above-mentioned scaffolds do not have the ability to use large loads and large spans, there is no rigid locking device for their longitudinal connection parts, and the space tension and stability measures are also limited, which also limits their lap height.

Abstract

The invention discloses a disc lock type scaffold constructing system which comprises basic structural member portions (including upright rods, horizontal rods, diagonal rods, sweeping rods and the like), stabilizer portions (including space stabilizing tie pieces, wall connecting members and the like), safety protection systems (including safety net systems, pedal anti-dropping locking interface devices, blocking and protective barriers and the like) and support adjusting portions (including adjustable bottom support members, formwork strut members, universal support members and the like). The disc lock type scaffold constructing system has the advantages that porous connecting discs and rotary lock butting systems are arranged on the upright rods, so that the upright rods, matched transverse rods, the diagonal rods, the tie pieces, safety nets and the like can be assembled to form the disc lock type scaffold constructing system with stable space structures, safety protection functions and ability of meeting different load requirements, basic elements and subsystems have structural association and dependence relations with one another, all structural members are series of standard members and can be produced on a large scale, and accordingly the disc lock type scaffold constructing system is truly safe, reliable and practical and is truly high in efficiency.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a disc-lock type scaffold construction system with safety locking and protection functions used in construction projects. Background technique [0002] At present, the common construction scaffolds at home and abroad include pipe buckle type, door type, bowl buckle type and disc buckle type. No matter what kind of scaffolding, there are many defects in use, mainly including: [0003] 1. The locking of the pipe fasteners of the pipe buckle scaffolding is carried by frictional force, which is easy to fall off and cause safety accidents, which has been eliminated in developed countries; [0004] 2. The bearing capacity of portal scaffolding is small, and the overlapping height is limited; the bowl-buckle scaffolding is supported by short-distance crossbars at right angles and uses a large amount of steel, so the lateral bearing capacity is poor and it is easy to collapse in l...
