At present, Aluminum Alloy template instead of the traditional template has been widely used, and its light weight, high strength, large size plate, less seams features useful to ensure the quality of construction, although the initial investment Aluminum Alloy template is relatively high, but can effectively shorten the construction period, improve construction quality, reduce unnecessary trouble two construction. Together, because the planning of aluminum film has the characteristics of standardization and diversification, so that he can adapt to any direction of the device and construction, and make the standardization of construction project has been effectively guaranteed and improved. In the aspect of economic benefit, Aluminum Alloy template and the traditional template with more upfront investment, are all over the look, the reason is the traditional wood template in spite of less upfront investment, but late into many, high benefit from the whole of the selection of aluminum mold. Together, because the aluminum alloy is environmentally friendly construction materials, has a high recovery rate and recovery value, salvage recovery rate can reach more than 80% of the original data quotation. In addition, the aluminum alloy template can be repeatedly used, saving the capital. In other words, the use of aluminum alloy templates, in addition to higher pre investment, the later investment is zero, which is also the reason for its economic benefits.
At present, there are several traditional construction templates in china:
1）The most traditional wood template, compared with the common poplar template and pine template, this template is relatively light, the money is slightly lower, but the durability is not too good, and the rate of repeated use is very low。
2）Steel formwork, steel strength is obviously very large. But the weight is too heavy, repeated use, high cost。
Plastic template, not afraid of water, low cost, durable, but the strength is not good。
Compared with the above three traditional templates, the aluminum template and repeated use are far ahead of the three common templates, which are of high strength and light weight, suitable for the South and some of the local tide. The most important is the aluminum template assembly after the end of a pouring, if it is the same story, like a cell that repeated building, using aluminum template, the duration of the price advantage is very significant, and the seam is fine, into the wall is very beautiful, the decoration is also very convenient。
Compared with traditional formwork, aluminum alloy template has the following advantages：
1）Short construction period: Aluminum Alloy construction formwork system for quick release system, a set of templates of normal construction can reach four or five days a construction unit, saving management costs (current Macao in the construction of the project -TN27 layer construction layer can be up to three days。
2）Repeated use less, uniform use of low cost, aluminum alloy building aluminum formwork system, select all kneading aluminum alloy profiles as raw material (6063-T6 or 6061-T6), a set of template construction can be used more than 300~50 times, uniform use of low cost。
3）The construction is convenient, high power: Aluminum Alloy construction formwork system is simple, convenient assembly, uniform component of 30KG/ square meters, completely by manual assembly, do not need any mechanical equipment to assist the construction workers (annoying generally only need a wrench or a small hammer, convenient and quick, skilled workers per person per day device device (with 20~30 square metres of wood CF: aluminum die for workers to wood workers 70~80% device, and does not require skilled workers, only need device for construction personnel training can be brief)。
4）High bearing capacity: aluminum alloy building template system, all parts are made of aluminum alloy plate assembly, after the system is assembled, constitute a whole structure, the stability is very good, the bearing capacity can reach 60KN per square meter。
5)Wide range of applications: the use of aluminum alloy template, suitable wall, horizontal floor, pillars, beams, stairs, windows, floating plate and other directions。
6) Effect of concrete appearance after stripping: Aluminum Alloy built after template removal, the concrete appearance quality of flat light, basically can reach the finish and water coagulation needs, without plaster, plaster can save cost。
7）No construction waste: Aluminum Alloy construction formwork system all accessories can be used repeatedly, the construction site after the removal, no waste, construction of environmental safety, clean and tidy。
8）Specification, versatility: aluminum alloy building template specification more, according to the project selection of different specifications, plate assembly used templates to rebuild the new building, only need to change the non-standard version of 20~30%, can reduce the cost。、
9) High recovery value: Aluminum Alloy built template is invalid, when the residual waste disposal, equally significant cost advantage (per square meter price recovery in about 400 yuan)。
10) Low carbon emission reduction: aluminum alloy building template system all data can be recycled data, consistent with the national construction project energy saving, environmental protection, low-carbon, emission reduction rules. Many developed countries have rules in the use of wood construction projects not only require the use of recycled materials template, template。
11）Support system is convenient: traditional construction methods, such as the middle floor, channel and other template construction skills throughout the selection of scaffolding, cost information. And the support of the root formwork is relatively less (using the independent support spacing 1200mm one), the operation space is large, the personnel pass, data transfer dredge, on-site easy to handle。
