During installing and using Ringlock Scaffolding,the considerations of the construction technology of ringlock scaffolding that you should know

The most widely used scaffolding products are ringlock scaffolding, and its construction safety requirements are also very strict. Only in accordance with the normative construction standards and correct use methods can the safety of construction operations and personnel be guaranteed. Let's talk about the construction technology of ringlock scaffolding. You must get!

At the construction site,There are two major steps to follow when using ringlock scaffolding:

1. First, you need to install the scaffold, and the accessories that make up the scaffold, such as the base, the pole, the diagonal rod, etc., are built in accordance with the requirements of the specification;

2. Next, the connection of the scaffold needs to be inspected, and the construction work can only be carried out after the inspection is qualified.

There are three points to pay attention to during the installation and use of ringlock scaffolding:

1. Check whether there is stagnant water on the scaffolding and other related accessories to ensure that the overall use specification meets the requirements for the use of the ringlock scaffolding, especially the verticality of the corner and the fracture.

2. Check whether there is any looseness in the connection, and whether safety measures such as personnel protection are in place to avoid any safety accidents.  

3. The ringlock scaffolding needs to be checked regularly during use to avoid unauthorized disassembly of the scaffold, and whether the inspection personnel are on duty with a certificate.  

Because the ringlock scaffolding has the characteristics of versatility, high efficiency, high bearing capacity, safety and reliability, and at the same time, it is not easy to cause problems in the process of use. It is simple and convenient to load and unload, and is easy to store. Therefore, engineering construction plays an important role in many of our construction industries.

Different categories of Ringlock Scaffolding and the corresponding characteristics

Features of ringlock scaffolding

The pole is made of Q345B material, so the bearing capacity is high, especially the 60 series ringlock scaffolding, which is much higher than other traditional scaffolding. The same project can greatly reduce the amount of scaffolding, save labor and construction period, and the surface is hot-galvanized, and the overall appearance is . However, due to the high production cost of scaffolding, there are still some applicable projects from economic considerations.

The most commonly used engineering category of ringlock scaffolding

High formwork, large span, cantilevered structure, heavy support, safe climbing ladder for deep foundation pits,

High mold type

Since the ringlock scaffolding is characterized by the high bearing capacity of the vertical poles, the spacing of the cross-bars can be longer than ordinary scaffolding, so the number of vertical poles, top supports, and bottom supports are all reduced year-on-year. For projects of the same scale, the overall amount of scaffolding can be reduced by 30% —50%, the corresponding transportation, warehousing, loading and unloading costs can be reduced, due to the fast installation, the labor is also greatly reduced, so that the higher production cost of the ringlock scaffolding can be amortized as a whole, so this type of project is the most suitable.

Large span

Because of the built-in diagonal pull rod, it is equivalent to the role of scissor support, which can make the whole frame body become countless triangular geometric invariants, and the safety factor is very high. For large-span scaffolding projects with low bearing capacity, on the basis of ensuring the safety factor, it can also save considerable material and labor compared with traditional scaffolding, etc. This type of project is also very suitable

Overhanging structure

Because the ringlock scaffolding is equipped with diagonal rods, it can be erected with a cantilever structure, which is convenient and quick. For scaffolding on the market, only steel pipe fasteners can be used to erect overhanging scaffolding, but the installation operation is more complicated, time-consuming, labor-intensive, and material-consuming. The bowl-buckle scaffold, although it can also have diagonal rods, is difficult to find in the domestic market.

Heavy support

For example, bridge projects and projects with large concrete beams and thick slabs can take advantage of the large bearing capacity of ringlock scaffolding, and it is also the most widely used type in actual projects.

Safe Climbing Ladder for Deep Foundation Pit

Traditional horse tracks for deep foundation pits are mostly built with steel pipe fasteners, which are more random, time-consuming and laborious to erect, and are aesthetically pleasing and not standardized enough. The other is the construction of steel stairs. The biggest drawback is that it must be hoisted and installed, and transportation and storage are not as convenient as scaffolding. It can only be used for climbing ladders and has a single purpose.

The ringlock scaffolding can complete all erection works with only a hammer, and it is very safe, standardized, beautiful, and convenient for transportation and storage. It can be used as a scaffold after dismantling and can be used in many places.

Quality standards that should be met by the scaffolding before leaving the factory

Because of its safety and beauty, material saving and high efficiency, fast construction and other advantages, ringlock scaffolding has won unanimous praise and praise from many construction companies in recent years, especially in the field of difficult and risky formwork support such as high formwork.

The reason why ringlock scaffolding can have outstanding performance in various fields is closely related to product function design, but it is also inseparable from the excellence of manufacturing.

The "Technical Specification for Safety of Socket-type ringlock scaffolding in Construction JGJ231-2010" has made detailed and clear regulations on the production quality requirements. Let's take a look at what tests a qualified ringlock scaffolding has to go through before it leaves the factory.

1. The welding of rods should be carried out on special process equipment, and the welding parts should be firm and reliable. The welding wire should meet the requirements of the current national standards for carbon steel and low-alloy steel welding wire for gas shielded arc welding, and the effective weld height should not be less than 3.5mm.
