Recently, in the construction industry, a new type of material has been heated up by major companies. Do you know what kind of material it is?-Building aluminum formwork.

This material is widely used in some large real estate companies, such as Vanke, Country Garden, and Greenland. Vanke began to try to apply aluminum formwork to real estate construction in 2012-2013, and Country Garden borrowed from Vanke's aluminum formwork technology and also applied aluminum formwork to construction in 2015. So when it comes to aluminum formwork, you may not be very familiar with it. In China, aluminum formwork may only be used in some large-scale industries at present, and there are only a handful of companies that can produce architectural aluminum formwork.

Aluminum formwork is called aluminum formwork system for construction. It is a new generation of new formwork support system after bamboo and wood formwork and steel formwork. The application of the aluminum formwork system in the construction industry has improved the overall construction efficiency of the construction industry, including building materials and manual arrangements, which greatly saves a lot.

I believe everyone is familiar with wooden molds and steel molds, so does aluminum formwork really have such a big advantage?

1. Building aluminum formwork is regarded as a new generation of building materials in the field of construction in our country. Our country's construction industry is a key industry for wood consumption, and the annual wood consumption accounts for about 30% of the country's total wood consumption. Among them, the wooden formwork used in the field of construction, because of its low recycling rate, causes a lot of waste of wood resources. However, aluminum alloy formwork has the advantage of being recyclable. Therefore, in the case of our country's wood supply and demand contradiction and environmental protection pressure, it is even more important to vigorously develop and promote new formwork materials such as aluminum alloy formwork and accelerate the implementation of the project of replacing wood with aluminum.

2. Compared with wooden formwork and steel formwork, it has the characteristics of good economy, high recycling value, fast construction progress, high construction efficiency, safe and clean construction site, good construction image, low dependence on machinery, and wide application range.

Application and Splicing Advantages

Aluminum alloy building formwork is suitable for the use of formwork such as wall formwork, horizontal floor slab, column, beam, climbing form, bridge formwork, etc. Can be assembled into small, medium or large templates. The product is light in weight and can be assembled manually or mechanically hoisted after forming. The main connection method is wedge pin connection, and the construction usually only needs a wrench or a small hammer, which is convenient and quick. Before installation, only simple training is required for the construction staff; no matter how the aluminum formwork system is used, the basic methods and components are the same, and the construction staff can use it skillfully; the formwork has high precision and can save secondary plastering materials on the wall. And labor costs also ensure the quality of the building with a higher safety factor.

The aluminum alloy building formwork has a high recycling value and a lower average cost. Many regions have a history of more than ten years, and their use is becoming more and more popular. Because of its obvious advantages, it is also a renewable energy source. It responds to the call of ‘’Four energy-saving and one environmental protection" and is the future development direction. The aluminum alloy formwork market has a bright future.

Ten Advantages of Aluminum Formwork

One of the advantages of aluminum formwork: high construction efficiency and short cycle: the aluminum alloy building formwork system is a quick-release mold system, which can be removed in 18-36 hours, so only one layer of aluminum formwork and three layers of single supports are required. Use, normal construction can reach one floor within 4-5 days, thus greatly shortening the construction period, saving management costs for the construction unit, and shortening the development cycle for real estate developers.

The second advantage of aluminum formwork: reusable and low cost: all parts of the aluminum formwork system can be reused, and the aluminum formwork system uses integral extrusion to form aluminum alloy profiles as raw materials (6061-T6), and a set of formwork specifications can be reversed. Use more than 300 times, the use cost is low.

The third advantage of aluminum formwork: easy construction and high efficiency: the aluminum formwork system is simple and convenient to assemble, and only needs to increase the standard board proportionally during installation. The weight of the aluminum formwork is light 18-25 kg per square meter. The construction process is completely assembled and transported manually. , Does not rely on lifting machinery and equipment (workers usually only need a wrench or a small hammer, which is convenient and quick), and each installer can install 20-30 square meters per day (aluminum formwork installers can save 30% compared with wooden formwork, and no A technician is required, and the construction staff only needs to be trained for 1 hour before installation).

The fourth advantage of aluminum formwork: good stability and high bearing capacity: the aluminum formwork system is all assembled by aluminum formwork. After the system is assembled, it forms an overall frame with good stability. The bearing capacity can reach 60KN per square meter. There will be a mold expansion accident.

The fifth advantage of aluminum formwork: a wide range of applications: the aluminum formwork system is suitable for all building components, such as load-bearing walls, columns, beams, floors, stairs, balconies, etc., which can be completed by pouring cement at one time.

Sixth advantage of aluminum formwork: good concrete surface effect after demoulding: After the aluminum formwork is demolished, the concrete surface quality is smooth and clean, which can meet the requirements of finishes and fair-faced concrete, without the need for plastering, which can save the cost of secondary plastering.

Seventh advantage of aluminum formwork: no construction waste on site, safer construction: all parts of the aluminum formwork can be reused, there is no rubbish on site after demolding, no rust, no fire hazard, no nails on the installation site, no The remaining wood chips, wood pins and other construction debris from the chainsaw, the construction site is tidy, will not generate a large amount of construction waste like using wooden templates, and fully meets the green building construction standards. Through the use of lightweight panels, it is ensured that the construction personnel can be on the panels Work safely.

The eighth advantage of aluminum formwork: one-time design, high precision, and strong practicability: one-time design and molding according to construction drawings, integral pouring, tight construction and high accuracy, ensuring the overall strength and service life of the building, and it is very suitable for standard high-rise buildings. For super high-rise buildings and multiple buildings of the same family, the aluminum formwork can be assembled with different specifications of plates according to the project. When the used formwork is rebuilt into a new building, only about 20% of the non-standard plates need to be replaced.

Nine of the advantages of aluminum formwork: high recovery rate and large residual value: aluminum alloy materials can be recycled all the time. After the aluminum formwork system is scrapped, the residual value is high when the waste is processed. All the materials of the aluminum formwork are renewable materials, which meet the requirements for energy saving, environmental protection, low carbon, and emission reduction of construction projects, and the industrial policy of sustainable development.

The tenth advantage of aluminum formwork: Few supporting systems and easy walking: In traditional construction methods, formwork construction techniques such as floor slabs and platforms generally use full-floor brackets, which consumes labor and materials. The bottom support system of the aluminum alloy formwork adopts "single-pipe vertical independent" support, with an average spacing of 1.2 meters, no need for horizontal or inclined support support, large operating space, smooth passage of construction personnel, smooth material handling, and easy and convenient removal of single supports. Easy to manage.

As a new type of environmentally friendly and energy-saving building turnover formwork material, aluminum alloy formwork will be a trend in future development. In fact, friends who do construction abroad must know that aluminum formwork construction has already been implemented abroad. At the same time, Talents for aluminum formwork design are also very scarce in the future. From a domestic perspective, large enterprises such as Vanke have already begun to use aluminum formwork. Driven by some large enterprises, it is believed that aluminum formwork will soon become popular in the construction industry. .
