[China Aluminum Network] The current domestic architectural templates are more traditional in the following categories:
1) Compared to the traditional wood formwork, poplar formwork and pine formwork are more common. This kind of formwork is relatively light and the cost is slightly lower, but its durability is not very good, and its reusability is very low.
2) The steel formwork, as its name suggests, is steel and its strength is very high. However, its weight is too heavy and it is well reused. The cost is extremely high.
Plastic template, not afraid of water, low cost, durable, but not strong enough.
Compared with the above three kinds of traditional templates, aluminum templates and repeated use are much earlier than the first three kinds of common templates, strong and light weight, not rust, suitable for the South and some of the tide. The main advantage is that once the aluminum formwork is assembled, it can be poured once. If it is the same floor, the building sample is repeated like a residential area, and the aluminum template is used. The advantages of the construction period and price are obvious. And the patchwork is very fine, the wall is very beautiful, and the post-decoration is also very convenient.
Relative to the traditional template aluminum alloy template has the following advantages:
1) The construction period is short: the aluminum alloy building formwork system is the quick release formwork system, and the normal construction of one set of templates can reach the fourth or fifth day floor, which greatly saves the management cost of the construction unit (currently under construction in Macau - TN27 public housing construction Up to three days on the first floor.
2) Repeated use, low average cost of use: Aluminum alloy construction aluminum formwork system uses aluminum alloy profiles formed by integral extrusion as raw material (6063-T6 or 6061-T6), a set of template specification construction can be flipped to use 300- More than 500 times, the average cost of use is low.
3) Convenient construction and high efficiency: The aluminum alloy building formwork system is simple and convenient to assemble, with an average weight of 30kg/m2. It is completely assembled by hand and does not require the assistance of any mechanical equipment (employee construction usually requires only a wrench or a small hammer. Convenient and quick), skilled installers can install 20-30 square meters per person per day (compared with wood model: aluminum mold installation workers only need 70-80% of the wood mold installation workers, and do not need skilled workers, just before installation Simple training for construction staff can be.)
4) Good stability and high bearing capacity: All parts of the aluminum alloy building formwork system are assembled from aluminum alloy plates. After the assembly of the system is completed, an overall frame is formed, the stability is very good, and the bearing capacity can reach 60 KN per square meter.
5) Wide range of applications: Aluminium alloy building formwork is suitable for the use of walls, horizontal floors, pillars, beams, stairs, windowsills, drift boards, etc.
6) Surface effect of concrete after demoulding: After the aluminum alloy construction template is demolded, the surface quality of the concrete is smooth and smooth, and the requirements for facing and fair-faced concrete can basically be achieved, and no need for renewal, which can save the expense of levitation.
7) No construction waste on site: All parts of aluminum alloy construction formwork system can be reused. After the construction is demolished, there is no garbage on site and the construction environment is safe, clean and tidy.
8) Standards and versatility: Aluminum alloy building formwork has many specifications, which can be assembled with different specifications according to the project; when replacing a used building template with a new building, only 20-30% of non-standard plates need to be replaced to reduce cost.
9) High recovery value: After the aluminum alloy construction template is scrapped, when the waste disposal value is high, the average cost 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 formwork system are renewable materials, in line with the national regulations on energy saving, environmental protection, low-carbon, and emission reduction of construction projects. Many developed countries have already stipulated that construction projects are not allowed to use wood formwork and require the use of renewable materials.
11) The support system is convenient: In the traditional construction method, the template construction technology such as the floor slab and the platform generally adopts full hall brackets, which is labor-consuming. On the other hand, the supporting poles of the aluminum formwork molds are relatively small (with an independent support spacing of 1200mm), which allows a large operating space, free access to personnel, smooth material handling, and easy management on site.
