Quality Problems of Rental Scaffolding

Scaffolding Safety Reasons for Frequent Accidents

Since 2000, especially in the past year, China's construction industry has occurred many times the mold frame support system in a major collapse of security incidents in the construction process, in the behind these shocking case, we must clearly recognize scaffolding support safety incidents occurred due to many reasons, and there have recently been a growing trend. Through the analysis of the causes of these accidents, the reasons are generally focused on the following three aspects: First, the construction unit problems in design and design calculations, in order to save costs, reduce material expenses taken to reduce frame construction organization design material configuration program. Second, the construction workers at the site are not operating in accordance with the construction specifications, in the erection of the support system failed to correct the installation, safety training is not in place, and the scene lacks an effective safety oversight. Third, the scaffolding tower equipment itself has quality problems, steel, fasteners, materials and wall thickness is not up to standards and the loads is not enough, due to the larger force in tall mold base construction, prone to lead to point to area systemic collapse accident.



Scaffolding Quality is the Root Cause of the Frequent Problem

As we all know, all substandard, inferior quality products behind are mostly driven by economic interests. Specific to the template scaffolding pole leasing companies, operating income source is rent, rental supplies rent is calculated based on length, number and area of use, so the use of scaffoldings lower than the national standards thinner, lighter, or low-grade material as raw material supplies, leasing companies can get a lower purchase price more rentable materials. The use of materials such as steel, fasteners of non-standard products leasing companies in the leasing market because the cost is lower than those of normal material procurement company in accordance with the national standards, these companies often contract negotiated without the knowledge of the construction unit due have the advantage on the price of the bid, which provides for the use of poor quality materials market. If these substandard construction equipments enter lease circulation market, it will bring great risks to construction safety.

The Fundamental Way to Solve Scaffolding Problem

Seen from the current situation, to solve this problem, we must strengthen the role of industry associations, the establishment of industry self-regulatory organization, through the development of a series of standards, norms, strengthen propaganda, and actively cooperate with the authorities at all levels to guide the construction unit with legitimate business the leasing company for business cooperation, there is no market for those who take cut corners, opportunistic and other illegal means to operate the enterprise, is the fundamental way to solve the quality problems of scaffolding.

A Variety of Mobile Scaffoldings

What is a Mobile Scaffold?

Mobile scaffolding refers to the various erection brackets on the construction site for workers to operate the vertical and horizontal transport. It is a generic term of the construction industry, refers to the formwork used on the construction site in the exterior wall, interior or higher storey and the place that is unable to do the direct construction. Mainly it is convenient for the construction workers to easily up and down to work or perimeter security network maintenance and high-altitude mounting member, simply put that is to put on airs, scaffolding making materials are usually: bamboo, wood, steel or synthetic materials. Some workers use scaffolding tower when the template is used, in addition to widely used in the advertising industry, municipal, transportation, roads and bridges, mining and other sectors.



Development Course of Mobile Scaffold

Mobile scaffolding formwork, as the basis of building facility, is widely used in a variety of large and small construction sites. And it plays a great supporting role. The course of its development is quite long, nearly being the final perfect from the imperfect start step by step, and after a long process. Mobile scaffolding is first successfully developed by the United States, Europe, Japan and other countries began to develop and use the scaffolding early in 1960s. It has the features of simple assembly and disassembly, good bearing performance, the use of safe and reliable, the fast development of mobile scaffolding in a variety of new scaffoldings, it is the developed earliest and the largest usage in Europe and the United States, Japan and other countries, its use accounts for about 50% of the various types of scaffolding. China from the late 1970s has imported from Japan. The United States, the United Kingdom and other countries and also introduce this scaffolding.

The Major Parts of Mobile Scaffolding Poles

The mobile scaffolding is composed of main box, cross box, cross bracing, scaffold boards and adjustable stand. The cross-bracing is also known as helical rod, and mobile scaffolding is a vertical cross-type rod connecting two masts. At the both ends of the rod, there are pin holes, when assembly, lock with the lock pin firmly on the mast pole. Surface treatment: electroplating (cold galvanizing), dip zinc (hot dip galvanized) Caster is also known as ground round, and it can be installed in the lower part of the mobile scaffold composed of mobile scaffolding. It is available as mechanical and electrical installation.

Scaffolding that Can Save a Lot of Wood

Significance of New Scaffolding

A new building with a template composite structure can obtain four national patents, and this is a thing that the designer of the Changli farmer entrepreneurs Wei Zhiguang has never thought of. Industry experts commented on the composite structure of the set of template like this: "the successful development of the template system for the construction industry is a revolutionary innovation, it can greatly improve the efficiency in the building industry, and if do general promotion, the annual savings for the state timber can be up to 2000 million cubic meters."


The Invention of New Building Scaffolding

The 44-year-old Wei Zhiguang once worked as a construction worker and carpenter, and then he starts up a decorative interior design company. He found that when the workers pouring concrete construction, structures assembled wooden structure of the bracket takes great time and effort, and the wood used to build scaffolding tower would became fuelwood after several times use. The project started construction of the country each year tens of thousands, and the resulting waste timber amazing. So, Wei Zhiguang initiation of an idea: If you could invent an installation to facilitate the demolition, the attrition rate and the low modular template support structure, it not only can save hours of work, but also can save wood. The love-pondering Wei Zhiguang began his research in 2002. Access to large amounts of data, he found, are not a new building with template support system at home and abroad. So, Wei Zhiguang acted quickly to form a small team to the edge of the edge manufacturing, he is responsible for drawing paper and others responsible for the production. Test failed after 20 times, and has invested more than 200 million of development fee, in 2004, the new building structure using a combination of templates scaffolding poles finally successfully developed. In 2005, this new building, the template composite structures, and its technology beams, template supporting combination structure and template support mandrel respectively won the olecranon card four national patents.

The Advantages of the New Scaffolding

The new building with template combination structure is made of high-performance cold rolled steel, a smart telescopic structure, the installation and removal and height, and pitch adjustment flexibility and does not need to use a timber, a round nails and wire fixed in greatly when improve efficiency and at the same time, saving a lot of wood and other supplies. After testing, the use of the construction technology, 4 group people and 8 hours to install the template structure of 400 square meters, and the same amount of work, if use the traditional technology requires a minimum of two days.
