Advantages of aluminum alloy template:
1.Short construction period: the aluminum alloy building formwork system is quick release formwork system, a set of formwork can reach three or four days of normal construction of a floor, greatly saving the contractor's management costs
2.Repeated use times, low average use cost: aluminum alloy building aluminum formwork system USES aluminum alloy profiles formed by overall extrusion as the raw material alloy 6061-t6, a set of formwork specifications construction can be used for more than 300-500 times, low average use cost.
3.Construction is convenient, high efficiency: aluminum alloy construction template system assembly is simple, convenient, average weight 30 kg/m2, completely by artificial assembly, need no help from any mechanical equipment, construction workers are usually only need a wrench or a small hammer, convenient and quick), the installation of skilled workers can be installed 20-30 square meters per person a day (compared with wood pattern: aluminum mold installation workers only need to block 70-80% of the workers, and there's no need to skilled workers, just before the installation simple construction personnel training).
4.Good stability and high bearing capacity: all parts of the aluminum alloy building formwork system are assembled by aluminum alloy plates. After the system assembly is completed, a whole frame is formed with good stability.Carrying capacity up to 60KN per square meter.
5.Wide range of applications: aluminum alloy building template suitable for the use of wall, horizontal floor, pillars, beams, stairs, window sills, floating board and other positions.
6.Concrete surface effect after mold removal: after mold removal of aluminum alloy building formwork, the quality of the concrete surface is smooth and smooth, which can basically meet the requirements of facing and fair-faced concrete. There is no need for batch swing, which can save the cost of batch swing.
7.No construction waste on site: all parts of the aluminum alloy building formwork system can be reused. After the construction and mold removal, there is no waste on site, and the construction environment is safe, clean and tidy.
8.Standard, strong universality: aluminum alloy building template specifications, according to the project can use different specifications plate assembly;When used templates are used to rebuild new buildings, only 20-30% of the non-standard boards need to be replaced, which can reduce the cost.
9.High recovery value: after the scrap of aluminum alloy building template is scrapped, when the residual value of waste treatment is high, the cost-sharing advantage is obvious (the recovery price per square meter is about 400 yuan).
10.Low-carbon emission reduction: all materials of the aluminum alloy building template system are liveable materials, in line with the national regulations on energy conservation, environmental protection, low carbon and emission reduction for construction projects.Many developed countries have already stipulated that wooden formwork should not be used in construction projects.
11.The support system is convenient: in the traditional construction method, the formwork construction technology such as floor slab and platform generally adopts full hall support, which costs a lot of labor and materials.On the other hand, there are relatively few supporting rods on the site of supporting die of aluminum formwork (one with an independent supporting interval of 1200mm is adopted), which has large operation space, personnel passage, smooth material handling and easy site management.
Aluminum formwork construction of concrete structure size easy to control, precision butt, easy to mold characteristics, to ensure the surface of concrete smooth, smooth, avoid the traditional wood construction of a large number of construction waste (wood chips, concrete slag) disadvantages.Aluminum alloy template technology with quick release system by artificial resulto, changed the traditional rely on tower crane and construction method of discharging platform, effectively speed up the construction progress, shorten construction period, reduce the labor intensity, improve the efficiency of the construction, the construction process of green environmental protection, energy saving, low carbon in line with the development of green environmental protection new building concept.
Aluminum template with high strength, light weight, high impact strength, easy to assemble and disassemble, green environment protection, cold and high temperature resistance can be used normally within the range of 300 times or more,100% recyclable, easy to recycle, high value.The integrated cost can save more than 30% of the cost compared with the wooden template, which is the ideal template for the 21st century environmental friendly and economical housing construction.
Aluminum formwork technology with quick release system by artificial resulto, changed the traditional rely on tower crane and construction method of discharging platform, effectively speed up the construction progress, shorten construction period, reduce the labor intensity, improve the efficiency of the construction, the construction process of green environmental protection, low carbon energy saving, in line with the development of green environmental protection new building concept.
At present, steel formwork, wood formwork, bamboo formwork, plastic formwork and aluminum alloy formwork are widely used in concrete casting in construction industry.Steel formwork is heavy, easy to rust, and easy to be cemented with concrete in the process of concrete casting, so it is difficult to demould;Although the weight of the wood template is light, its strength is low, it is not waterproof, easy to mold and rot, low reuse rate, the need to consume wood resources, is not conducive to the protection of ecological environment and forest resources;The disadvantage of bamboo template is low reuse rate and non-recyclable;Plastic template rigidity is poor, easy to change, and high cost.These formwork durability is not good, the production standard degree is low, can not ensure the quality of concrete engineering, and the construction speed is slow, the turnover of the formwork is low, the material consumption is large.

There is no need for mechanical hoisting, the construction site is clean and tidy, and the management cost of civilized construction is low;4. High recovery value, residual value of aluminum formwork is up to 90% of the price of aluminum ingots.
Third, significant social benefits
1. Energy conservation and environmental protection, low carbon emission reduction, a model of circular economy;2. Civilized construction to avoid secondary pollution on the construction site;3. Significantly reduce construction intensity and protect labor.
Aluminum formwork system, made of high strength aluminum alloy, strong bearing capacity but light and flexible disassembly.It is convenient to realize one casting, which makes the site operation simple and easy to operate, and saves a lot of labor quantity and labor cost on site.Moreover, the aluminum formwork system can be used repeatedly, and because of the update of the formwork material, the waste and consumption of forest resources in the construction industry are greatly reduced.Moreover, it is the integration of building formwork and support system from construction equipment to construction technology, providing a complete solution for concrete pouring construction.
The aluminum formwork system has the following nine features:
1. Lightweight: the products are all made of high-strength aluminum alloy, with an average weight of 25 kg per square meter.About 2.5 square meters of the largest size of the template, can be easily carried by a person.
2. Flexibility: the construction method of general ground assembly and hoisting by tower crane can be adopted.In the tower crane insufficient construction site, can be manually disassembled.
3. Simple: the main parts are pins, wedges and wall inserts, which can be installed and removed quickly with only a hammer and a little trained manual labor.
4. High efficiency: integrated, standardized and modular system design can facilitate the realization of one casting, make on-site operation simple and easy to operate, and greatly save the number of on-site labor and labor costs.Effectively shorten the construction period, usually every 3-4 days to complete a floor assembly and pouring.
5. High strength: with the latest technology of aluminum alloy materials and reasonable template structure design, the bearing capacity of aluminum template system can reach 60KN/m, which is equivalent to the design bearing capacity of all-steel large template.
