Disk-lock Scaffolding

Disk-lock Scaffolding is a new type of modular steel pipe support system,whose core feature is to connect uprights,crossbars,and diagonal bars through disc-shaped nodes to form a stable spatial grid structure.Compared with traditional clip on scaffolding,it has the advantages of structural stability,efficient disassembly and assembly,safety and reliability,and strong turnover.It has become one of the mainstream support and scaffolding systems in construction and is widely used in projects such as bridges,subways,buildings,and large venues.

1、Core Composition and Node Design

Main components

Pole:Bearing core,made of high-strength Q355B steel pipe(partially Q235),with standardized length(such as 0.5m,1m,1.5m,2m,etc.),can be extended by docking sleeves;Weld a circular node every 500mm(or 600mm)on the pole.

Horizontal bar:Connect adjacent upright poles,with horizontal bar joints welded at both ends with plugs that can be inserted into the holes of the upright pole disc and fixed with wedge-shaped pins.

Diagonal bar:enhances overall stability,divided into vertical diagonal bars(scissor braces)and horizontal diagonal bars.The joints at both ends are similar to horizontal bars,but the angle is adapted to the diagonal force,usually arranged at 45°or 60°.

Disc Node:The core connecting component on the upright pole,which is a steel plate disc with a thickness of 8-10mm.It has 8 holes evenly distributed around the circumference(some of which are 6),used to insert plugs for horizontal and diagonal bars.It is quickly fixed by wedge-shaped pins(self weight or tapping locking),and has strong rigidity and direct force transmission.

Auxiliary components:including adjustable base(adjusting pole height to adapt to uneven ground),adjustable bracket(supporting formwork or upper structure),pedals,guardrails,sweeping poles,etc.

Node advantage

The circular node is connected by a"plug+wedge pin",replacing the traditional bolt fastening of fasteners,and has self-locking function(the wedge-shaped pin becomes tighter when loaded).The node has excellent shear and torsion resistance,and the overall stability of the structure is much higher than that of the fastener scaffold(fasteners are prone to deformation due to loose bolts).

2、Core Performance and Advantages

Stable structure and high bearing capacity

The upright pole is made of high-strength steel,with a yield strength of 355MPa(traditional Q235 steel pipe is 235MPa),and a higher compressive bearing capacity;The rigid connection of circular nodes forms a geometrically invariant system for the entire scaffold,with a lateral stiffness 3-5 times that of clip on scaffolding.It can be used for high formwork(such as formwork support exceeding 8 meters in height),large-span structures(such as sports stands),and other scenarios with large loads.

The load transmission path is clear:the upper load is transmitted through the upright pole→adjustable base→foundation,and the horizontal force is transmitted through the horizontal bar and diagonal bar.The nodes do not slip,and the deformation is small,which can effectively control the construction accuracy(such as floor elevation deviation).

Efficient disassembly and assembly,saving construction time

Without the need for wrenches or other tools,the installation and removal of horizontal and diagonal bars can be completed by manually tapping the wedge pins.The speed of single person spacing can reach 3-5 minutes/cubic meter,which is 2-3 times that of clip on scaffolding,greatly reducing labor costs and installation time.

The standardization level of components is high(fixed length),and there is no need for cutting or processing on site,reducing material waste and construction waste,and facilitating quantity counting and management.

Safe and reliable,reducing risks

The node self-locking function avoids the risk of frame instability caused by loose bolts in traditional fasteners;The verticality of the upright pole is easy to control(with fixed disc spacing,which can be used as a reference),and the diagonal pole layout is standardized(set at each step according to design requirements),with strong overall anti overturning ability.

Protective components such as pedals and guardrails can be quickly connected to the frame,forming a closed working space and reducing the risk of falling from heights;The adjustable base and bracket have high adjustment accuracy(usually±50mm),ensuring that the support surface is flat and stressed.

High turnover frequency and good economic efficiency

Steel has high strength and wear resistance.The circular nodes are welded firmly,and the components are not easily damaged.The normal turnover can reach more than 300 times(about 100-150 times for clip on scaffolding),and the long-term use cost is much lower than that of traditional scaffolding.

During the disassembly and assembly process,the component loss rate is low(without issues such as missing fasteners or slipping bolts),and the recycling value is high,making it suitable for large-scale construction enterprises to purchase and use in a centralized manner.

3、Applicable scenarios

High formwork engineering:For cast-in-place concrete floor slabs and beams with a floor height exceeding 8 meters,use their high bearing capacity and stability to control structural deformation.

Bridges and municipal engineering:such as bridge abutments,pier column formwork support,and scaffolding around subway station foundation pits,which can adapt to complex terrain and load requirements.

Large industrial plants:such as the operating platform and support used in the installation of steel structure plants,which require frequent disassembly and high safety requirements.

Group building:such as standardized construction of residential buildings,components can be rotated in batches to improve construction efficiency.

Emergency rescue:A temporary rescue platform built after a disaster can be quickly put into use due to its fast disassembly and good stability.
