The Development of Formwork Scaffolding

图片
  In the early 1970s, China's building structure was mainly brick structure, and the shuttering used in construction was mainly wooden formwork. Since the 1980s, with the promotion of the policy of replacing wood with steel, various new structural systems have emerged, reinforced concrete structures have increased rapidly, and steel formwork has become popular in construction. Since the 1990s, China's building structure system has developed greatly. With the large-scale infrastructure construction, the construction of expressway, railway, urban rail transit, high buildings, super high buildings and large-scale public buildings, new requirements have been put forward for formwork and scaffolding  construction technology. In China, the pattern of combined steel formwork has been broken, and has gradually changed into a pattern of coexistence of various types of formworks, and the development speed of new formwork is very fast.   Wood formwork: the formwork made of wood. The commo

  5. It is widely used. Aluminum alloy formwork is suitable for wall, horizontal floor, column, beam, staircase, windowsill, floating slab, etc.;   6. The concrete surface effect is good after formwork removal. After the aluminum alloy formwork is removed, the surface quality of the concrete is smooth, which basically meets the requirements of the finish and fair faced concrete. There is no need to carry out batch swing, which can save the cost of batch swing;   7. There is no construction waste on site. All accessories of the aluminum alloy formwork system can be reused. After the formwork is removed, the construction environment is safe, clean and tidy;   8. It is standard and universal. There are many specifications of  aluminum alloy formwork , which can be assembled according to the project; when the used formwork is rebuilt into a new building, only 20-30% of the non-standard boards need to be replaced, which can reduce the cost;   9. The recycling value is high. After the alumin

  1.The construction period is short.The aluminum alloy formwork system is a quick dismantling formwork system. A set of formwork can reach one floor in four or five days under normal construction, which greatly saves the management cost of the contractor;   2. The repeated use times are more and the average use cost is low. Aluminum formwork system of aluminum alloy building uses aluminum alloy profile formed by overall extrusion as raw material (6063-T6 or 6061-T6), and a set of formwork can be used for more than 300-500 times, with low average use cost;   3.Convenient and efficient.  Aluminum alloy formwork  system is simple and convenient, with an average weight of 35kg/m. It is completely assembled by hand without the assistance of any mechanical equipment (workers only need a wrench or a small hammer, which is convenient and fast). Skilled installation workers can install 20-30 square meters per day (compared with wood mold: aluminum mold installation workers only need 70-80% of

How to Find a Good Scaffolding Company

  Many people think that scaffolding is only an auxiliary tool, as long as it can be used.However, this view is very ridiculous, because scaffold is not only an auxiliary tool, but also a barrier to ensure the safety of users. Therefore, it is very important to choose the scaffold companies with excellent product quality.   When purchasing scaffold, we should first understand the scaffold industry. In reality, the types of scaffolding are not single, and different types of scaffold have different functional characteristics. In order to find regular  scaffolding manufacturers in china , their scale should be carefully analyzed by users.   Different from other high-tech products, the design and production technology content of scaffolding are limited. We can look over its production process, spraying and other surface treatment process, and then we will be able to quickly identify which scaffolding company is good. Therefore, in order to ensure the quality of scaffold products, it is rec

How to Identify the Quality of Scaffolding When You Buy It

  1. Looking at scaffolding's material When choosing the scaffolding, you can learn about the material from the seller and see whether the first-grade steel pipe is used. Many small workshops lower the market price, and then mix the first-grade steel pipes and the second-grade steel pipes. The second-grade steel pipe is prone to bulging and cracking in the construction site, causing safety accidents. Therefore, it is very important to choose scaffolding according to material.   2. Looking at scaffolding's appearance The appearance mainly depends on the consistency of glazing color, flatness, surface gloss, smoothness, the degree of sintering on the back, brand trademark, etc.   3. Looking at scaffolding's water absorption The less water absorption, the better. Poor freezing resistance due to high water absorption. The inspection method is to compare the weight difference between the dry scaffolding and the soaked scaffolding, which is the moisture content. According to the

Can Scaffolding Really Solve the Problem of Corporate Aerial Work?

  The materials used by the manufacturer for scaffolding are generally bamboo, wood, steel pipe or synthetic materials. Some projects also use scaffolding as templates. In addition, scaffolding is also widely used in the advertising industry, municipal administration, traffic roads and bridges, mines and other parts. It refers to the various brackets erected by workers on the construction site to solve the problem of vertical and horizontal erection.   In order for construction personnel to work up and down or to protect the outer safety net and install components at high altitude. To put it bluntly, it is to build a shelf. Different types of construction use scaffolding and  scaffolding shuttering  supports for different purposes. There are two types of scaffolding: comprehensive scaffolding and single-item scaffolding. All industrial and civil construction units that can calculate the construction area and are generally contracted by a construction unit shall perform the induction sc

Why is Scaffolding Prone to Collapse?

  Scaffolding is easy to cause casualties in various constructions. Why do such accidents happen frequently? According to statistics, the phenomenon of non-standard scaffolding at some construction sites is still common, which has led to the repeated occurrence of scaffolding collapses. Specifically, there are following situations:   1. The raw materials of scaffolding do not meet the requirements, and the necessary inspections and tests are not performed before use.   There are clear rules for the materials and standards of scaffolding. Before the scaffolding is erected, it is necessary to inspect and test the steel pipe, fastener, base and steel (wood) scaffolding board outside the site. The scaffolding can be transported to the construction site for use only after it is recognized as qualified. For various reasons, contractors often seek economic benefits, so that a lot of non-conforming materials scaffold framework accessories into the construction site, which also leads to the col
