What are the advantages of ringlock scaffolding?

In recent years, in the Chinese construction market, ringlock scaffolding has gradually become the main Construction Scaffold, and cuplok scaffolding has gradually disappeared from everyone’s field of vision. Ringlock scaffolding is a new type of building a support system with diverse functions. According to different construction requirements, it can be constructed with different shapes and load-bearing capacity of single and group frame sizes, double-row scaffolds, support columns, support frames, and other functions. equipment.

Ringlock scaffolding is widely used in construction, municipal roads and bridges, rail transit, energy and chemical industry, aviation, and shipbuilding industry, large-scale cultural and sports activities temporary construction facilities, and other fields.

1. The main accessories of the scaffolding

The main accessories of Ringlock scaffolding are vertical, horizontal, diagonal brace, adjustable base, U-Head Jacks, etc.

Vertical: A circular connecting plate that can be buckled with 8 direction joints is welded every 0.5 meters. One end of the vertical is welded with a connecting sleeve or an internal connecting rod to connect the vertical.

Horizontal: It is composed of a plug, a wedge pin, and a steel pipe. The crossbar can be buckled on the vertical rod disc.

Diagonal Brace: The diagonal rod is divided into the vertical diagonal rod and horizontal diagonal rod. It is a rod to ensure the stability of the frame structure. The two ends of the steel pipe are equi pped with buckle joints, and the length is determined by the spacing and a step distance of the frame.

Adjustable base: a base installed on the bottom of the frame to adjust the height of the scaffold.

Adjustable U-head Screw Jacks: a screw jack installed on the top of the pole to accept the keel and adjust the height of the supporting scaffold.

2.Installation method of new type ringlock scaffolding

When installing, you only need to align the horizontal connector to the position of the ringlock plate, then insert the pin into the ringlock hole and pass through the bottom of the connector, and then hit the top of the pin with a hammer to make the arc surface on the horizontal joint tightly integrated with the vertical stantard.

The Vertical Standard is made of Q345B low-carbon alloy structural steel, Φ60.3mm, and the wall thickness is 3.2mm. The maximum load of a single standard is 20 tons, and the design load can be up to 8 tons.

The horizontal is made of Q235 material, the middle is 48.3mm, and the wall thickness is 2.75mm

The diagonal brace is made of Q195 material, Φ48.0mm, and the wall thickness is 2.5mm; the disc is made of Q345B material, and the thickness is 10mm; this system is equipped with a special vertical diagonal brace, instead of steel pipe fastener type vertical scissor brace, vertical rod synchronous design, opposite The verticality of the rod is synchronized to correct the deviation. According to the current engineering experience, the supporting scaffold in the ringlock can be erected at a height of 20-30 meters at one time.

3.The detailed breakdown of the scaffolding

4.Why is the ringlock scaffolding more and more popular?

Advanced technology: The ringlock connection method has 8 connections for each node, which is an upgraded product of the scaffolding currently used worldwide.
Raw material upgrade: The main materials are all made of vanadium-manganese alloy structural steel, whose strength is 1.5-2 times higher than that of traditional scaffolding ordinary carbon steel pipe (GB Q235).
Hot Zinc Process: The main components are treated with an internal and external hot-forged zinc anti-corrosion process, which not only improves the service life of the product, but also provides a further guarantee for product safety, and at the same time, it is beautiful and beautiful.
Large bearing capacity: Taking the heavy support frame as an example, the single standard (060) allows the bearing load to reach 140KN.
Less consumption and lightweight: In general, the spacing of the poles is 1.2 meters, 1.8 meters, 2.4 meters, and 3.0 meters. The stride of the crossbar is 1.5 meters. The maximum distance can reach 3 meters, and the step distance can reach 2 meters. Therefore, the consumption under the same support area will be reduced by 60%-70% compared with the traditional cuplok scaffolding support frame.
Fast assembly, convenient use, and cost-saving: due to the small amount and lightweight, the operator can assemble more conveniently, and the efficiency can be increased by more than 3 times. Each person can build a 200-300 cubic meter frame per day. Comprehensive costs (set-up and disassembly labor costs, round-trip transportation costs, material rental costs, mechanical shift fees, material loss, wastage costs, maintenance costs, etc.) will be saved accordingly. Generally, it can save more than 30%.

5.Compare to the cuplok scaffolding, what are the advantages ringlock scaffolding has?

6.Low purchase cost

Compared with the cuplok scaffolding, it saves more than 1/3 of the steel consumption. The reduction of steel consumption is in line with the national policy orientation of a low-carbon economy, energy-saving, and emission reduction. In addition to huge social benefits, it also provides a reliable and guaranteed formwork support system for construction units, which greatly reduces the purchase cost of enterprises.

7.Low tower construction cost

How to ensure the safety of ringlock scaffolding operation?

Firstly, find out the factors that affect the safety of ringlock scaffolding. There are three main aspects: one is the safety and reliability of ringlock scaffolding itself, the second is the safety protection measures of ringlock scaffolding, and the third is the safe operation of ringlock scaffolding. Let’s take a look separately.

Ruggedness and stability are the safe and reliable foundation of ringlock scaffolding. Under allowable load and weather conditions, the structure of ringlock scaffold must be stable without shaking, shaking, tilting, sinking, or collapsing.

To ensure the safety and reliability of ringlock scaffolding, the following basic requirements should be ensured:

1) The frame structure is stable.
The frame unit shall be of a stable structure; the frame body shall be provided with diagonal rods, shear braces, wall rods, or bracing and pulling parts as required. In the passages, openings, and other parts that need to increase the structural size (height, span) or bear the specified load, strengthen the rods or braces according to the needs.

2) The connection node is reliable.
The cross position of the rods must meet the requirements of the node structure; the installation and fastening of the connectors meet the requirements. The connecting wall points, support points and suspension (hanging) points of the disc-buckle scaffolding must be set at the structural parts that can reliably bear the support and tension load, and the structure check calculation should be carried out if necessary.

3) The foundation of the disc scaffold should be firm and firm.

Safety protection of disc scaffolding

The safety protection on the ringlock scaffold is to use safety facilities to provide safety protection to prevent people and objects on the rack from falling. Specific measures include:

1) Ringlock scaffolding

(1) Safety fences and warning signs should be set up on the job site to prohibit irrelevant personnel from entering the dangerous area.

(2) Temporary supports or knots should be added to the ringlock scaffolding parts that have not been formed or have lost structural stability.

(3) When using a seat belt, a safety rope should be pulled when there is no reliable seat belt buckle.

(4) When dismantling the ringlock scaffolding, it is necessary to set uplifting or lowering facilities, and throwing is prohibited.

(5) Movable ringlock scaffolds such as hoisting, hanging, picking, etc., should be supported and pulled to fix or reduce their shaking after moving to the working position.

2) Operating platform (work surface)

(1) Except that 2 scaffolding boards are allowed to be used for decoration ringlock scaffolding with a height of less than 2m, the working surface of other ringlock scaffolding shall not be less than 3 scaffold boards, and there is no gap between the scaffold boards. The gap between the faces is generally not more than 200mm.

(2) When the scaffold board is flat-joined in the length direction, its connecting ends must be tightened, and the small crossbar under its end should be fixed firmly and not floating to avoid sliding. The distance between the center of the small crossbar and the board ends should be Control in the range of 150-200mm. The scaffold boards at the beginning and end of the ring lock scaffold should be reliably bolted to the ringlock scaffold; when lap joints are used, the lap length must not be less than 300mm, and the beginning and end of the scaffold must be fastened firmly.

(3) The protective facilities facing the outer facade of the operation can use scaffolding boards plus two protective railings, three railings plus outer plastic woven cloth (height not less than 1.0m or set according to steps). Two levers are used to tie a bamboo fence with a height of not less than 1m, two railings are fully hung with safety nets or other reliable enclosure methods.

(4) The frontage and pedestrian transportation channels:
① Use plastic woven cloth, bamboo fence, mat, or tarpaulin to completely close the street surface of the ringlock scaffolding.
②Hang safety nets on the frontage, and set up safety passages. The top cover of the passage should be covered with scaffolding or other materials that can reliably bear falling objects. The side of the canopy facing the street should be provided with a baffle no less than 0.8m higher than the canopy to prevent falling objects from rebounding onto the street.
③ Pedestrian and transportation passages that are close to or passing through the ringlock scaffolding must be provided with tents.
④The entrance of the upper and lower ringlock scaffolding with a height difference should be provided with ramps or steps and guardrails.

The safe operation of using ringlock scaffolding

1) The use load must meet the following requirements

(1) The load on the working surface (including scaffolding boards, personnel, tools and materials, etc.), when the design is not specified, the masonry work frame load shall not exceed 3kN/㎡, and the other main structural engineering workload shall not exceed 2kN/㎡, The load of decoration work shall not exceed 2kN/㎡, and the load of protection work shall not exceed 1kN/㎡.

(2) The load on the work surface should be evenly distributed to avoid excessive loads being concentrated together.

(3) The number of scaffolding layers and simultaneous working layers of ringlock scaffolding shall not exceed the regulations.

(4) The number of paving layers and load control of the transfer platform between the vertical transportation facilities (Tic Tac Toe, etc.) and the ringlock scaffold shall not exceed the requirements of the construction organization design, and the number of paving layers and excessive stacking of construction materials shall not be arbitrarily increased.

(5) Lining beams, fasteners, etc. should be installed along with the transport, and shall not be stored on the ringlock scaffolding.

(6) Heavier construction equipment (such as electric welders, etc.) shall not be placed on the ringlock scaffolding.

2) The basic components and connecting wall parts of the scaffold shall not be dismantled arbitrarily, and various safety protection facilities of the scaffold shall not be dismantled arbitrarily.

3) Basic rules for the correct use of disc scaffolding

(1) The materials on the working surface should be cleaned up in time to keep the working surface tidy and unobstructed. Do not place tools and materials randomly, so as not to affect the work safety and cause falling objects and hurt people.
(2) At the end of each work, the materials on the shelf have been used up, and the unused ones should be stacked neatly.
(3) When performing operations such as prying, pulling, pushing, and pushing on the working surface, take the correct posture, stand firm or hold a firm support, so as not to lose stability or throw things out when the force is too strong.
(4) When electric welding is performed on the working surface, reliable fire prevention measures should be taken.
(5) When working on the rack after rain or snow, the snow and water on the working surface should be removed to prevent slipping.
(6) When the height of the working surface is not enough and needs to be raised, a reliable method of raising shall be adopted, and the height of raising shall not exceed 0.5m; when it exceeds 0.5m, the paving layer of the shelf shall be raised according to the erection regulations.
(7) Vibrating operations (rebar processing, wood sawing, placing vibrators, throwing heavy objects, etc.) are not allowed on the disc-buckle scaffolding.
(8) Without permission, it is not allowed to pull wires and cables on the buckle scaffolding, and it is not allowed to use open flames on the buckle scaffold.
