Why do we promote ring lock scaffolding coupler?

Date: 02.08.2022 Viewed: times

In the process of daily inspection, it is found that tube clamp scaffolding coupler generally has problems such as substandard quality of steel pipe fasteners and irregular erection. Therefore, the ring lock scaffolding coupler came into being. The ring lock scaffolding coupler is a kind of scaffolding product with higher safety and efficiency, which has won unanimous praise from construction units and favored by local policies. At present, many places in the country have issued documents to promote the use of ring lock scaffolding coupler.

Ring Lock Scaffolding Coupler Advantage

First, the safety level of the ring lock scaffolding coupler is higher. The dimensions of the ring lock scaffolding coupler rods are all fixed modules, and the spacing and step distance are fixed, which basically avoids the influence of human factors on the structure of the frame. The ring lock scaffolding coupler adopts Q345B low-carbon alloy. Structural steel, the rod is not easy to deform and damage, and the bearing capacity and stability of the frame body are better.

The second is the better image of the civilized ring lock scaffolding coupler building. The surface of the ring lock scaffolding coupler is treated with hot-dip galvanizing, which is not easy to fall off paint and rust. Poor and other disadvantages, rainwater is not easy to erode, not easy to rust, and the color is uniform, and the large area of silver looks more atmospheric and beautiful. There are no loose screws, nuts, fasteners and other accessories on the ground in the frame erection area. The civilized construction in the area where the frame is erected is better.

Third, some cities have banned tube clamp scaffolding coupler, which may cause some unqualified tube clamp scaffolding coupler to flow into other cities, which will bring great security risks to the safety of supporting systems in other cities. Therefore, it is particularly necessary to comprehensively promote the application of socket-type ring lock scaffolding coupler.

Ring Lock Scaffolding Coupler

ring lock scaffolding coupler refers to a steel pipe bracket in which the vertical rods are connected by sleeves or intubation sockets, and the horizontal rods and inclined rods are clamped into the connecting plate with rod end buckle joints, and connected with wedge-shaped pins to form a steel pipe bracket with a constant structure and geometry. The socket type disc buckle type steel pipe bracket is composed of vertical rods, horizontal rods, inclined rods and other components.

Also known as plug-in scaffolding, roulette scaffolding, and buckle-disc scaffolding. The socket is a disc with a diameter of 133mm and a thickness of 10mm. There are 8 holes on the disc. The main component is made of φ48*3.5mm and Q345B steel pipe. Rod bottom with connecting sleeve. The cross bar is a plug with a pin welded on both ends of the steel pipe.

(1) Requirements for erection of double-row outer scaffolding:

The height of double-row outer scaffolding and formwork support should not exceed 24m; when it exceeds 24m, it should be specially designed.

The poles on the first floor of the scaffold should be staggered with poles of different lengths, and the vertical distance of the staggered poles should not be less than 500mm.

The frame size can be selected according to the needs of use, and the step distance of adjacent horizontal bars should be 2M. The vertical distance of the pole should be 1.5M or 1.8M. And should not be greater than 2.1M. The horizontal distance of the pole should be 0.9M or 1.2M.

The inclined rods of the double-row outer scaffolding shall be provided with a vertical inclined rod for every 5 spans and each layer along the longitudinal outer side of the frame body; or steel pipe scissor braces shall be provided between every 5 spans.

(2) Provisions for the setting of connecting wall parts

The connecting wall parts must be rigid rods that can withstand tensile and compressive loads. The connecting wall parts and the scaffolding facade and wall should be kept vertical. The connecting wall parts on the same floor should be on the same plane, and the horizontal spacing should not be greater than 3 spans. The distance between the outer sides should not be greater than 300mm.

The connecting wall piece should be set next to the buckle node with the horizontal rod, and the distance from the connection point to the buckle node should not be greater than 300mm; when the steel pipe fastener is used as the connecting wall rod, the connecting wall rod should be connected with the vertical rod by the right angle fastener.

When the lower part of the scaffolding cannot be erected temporarily, it is advisable to expand the scaffolding in multiple rows and set up inclined rods to form an additional trapezoidal frame in the shape of an outer slope. The additional trapezoidal frame can be removed after the upper connecting wall is erected.

(3) Provisions for setting up operation layers

The hook of the steel scaffold must be fully buckled on the horizontal rod, the hook must be in a locked state, and the scaffold on the working layer should be fully paved.

The outer side of the scaffolding frame body of the working layer should be provided with toe guards and protective railings, and the outer facade of the scaffolding should be covered with dense mesh safety nets; the upper protective railing should be set at a height of 1000mm from the working layer, and the middle protection railing should be set at 1000mm. The height from the working floor is 500mm.

When the gap between the working layer of the scaffold and the outer side of the main structure is large, a cantilever tripod should be set up to hang on the connecting plate, and a scaffold board that can form the inner side of the scaffold should be laid.
