The gap between my country's scaffolding and advanced

The scaffolding formwork supporting system is developed correspondingly with the progress of formwork engineering technology. Supporting systems in many countries have been developed into construction tools with their own characteristics, constituting various series of products. For a long time, supporting systems supporting wooden formwork projects have generally used wood supports and bamboo supports. At the beginning of the 20th century, Britain first applied the steel pipe bracket composed of joints and steel pipes, and gradually perfected and expanded it into a fastener-type steel pipe bracket. Because of the cumbersome processing, flexible disassembly and assembly, convenient handling, and strong versatility, this type of bracket will soon be applied to countries all over the world. In many countries, various types of fastener-type steel pipe supports have been constructed, and they have become one of the most commonly used formwork supports.

In the 1930s, Switzerland invented the adjustable steel pillar, which is a single-tube type pillar. The height of the steel pillar can be adjusted by using a screw tube device. Because of its simple structure, flexible assembly and disassembly, this kind of pillar has been widely used in various countries. Its structure has two types: thread exposed type and thread block type. Compared with the exposed threaded steel pillar, the threaded sealed steel pillar has the advantages of preventing dirt such as mortar from sticking to the thread, maintaining the thread, and not being damaged during operation and transportation. Therefore, thread-locked steel pillars are commonly used in some European countries. Since the 1980s, in order to increase the use of steel pillars, many countries have made improvements on the turntable and top attachments of the steel pillars, greatly increasing the use of steel pillars, and some have attached a foldable tripod at the bottom. The single-tube pillar can be installed independently, which is more conducive to the assembly and disassembly of the steel pillar.

Since the 1950s, the United States first successfully developed a door-shaped scaffold (door-type scaffold). Because of its simple assembly and disassembly, good load-bearing performance, and safe and reliable use, the deployment speed is very fast. In the early 1960s, countries such as Europe and Japan successively introduced and deployed this kind of scaffolding, and formed a door-type bracket system of various specifications. In France, Germany, Italy and other countries, trapezoidal, quadrilateral and triangular formwork support systems that are basically similar to the door-type support structure have also been developed and applied. In Europe, Japan and other countries, portal brackets are used the most, accounting for about 50% of all types of brackets. Many countries have also established many professional companies that consume various portal scaffolding systems.
