ã€ALUMINIUM NETWORK】Currently, aluminum alloy formwork has been widely used as a substitute for traditional formwork, and with its light weight, high strength, large board width, and less seaming features, it is useful to ensure construction quality despite the early stage of aluminum alloy formwork. The investment is relatively high, but it can effectively shorten the construction period, improve the construction quality, and reduce unnecessary troubles caused by secondary construction. Together, because the planning of the aluminum film has the characteristics of standardization and diversification, he has been able to adapt to any orientation of installation and construction, and has provided a useful guarantee and improvement for the standardization of construction projects. In terms of economic benefits, the aluminum alloy formwork and traditional formwork have invested a lot more in the early stages. The reason for this is the widespread expectation. The reason is that although traditional molds such as wooden molds are used less in the early stage, they are invested more in the later stage, and aluminum molds are used in the whole. The benefits are higher. Together, because the aluminum alloy is an environmental protection construction material, it has a high recovery rate and recovery value, and the salvage value recovery rate can reach over 80% of the original data quotation. In addition, aluminum alloy stencils can be reused repeatedly to save capital. In other words, the use of aluminum alloy formwork, in addition to the high initial investment, the late investment is zero, which is also the reason for its outstanding economic benefits.
At present, the domestic construction template is more traditional:
1) Compared to the traditional wooden templates, poplar templates and pine wood templates are commonly used for comparison. This kind of template is relatively light and relatively low cost, but the durability is not very good, and the repeated use rate is very low.
2) The steel formwork, which is literally steel, is very strong. However, the weight is too heavy to use repeatedly and the cost is extremely high.
Plastic template, not afraid of water, low cost, durable, but not strength.
Compared to the above three kinds of traditional template comparison, aluminum template and repeated use are far earlier than the first three common templates, strong intensity and light weight rust suitable for the south and some local tide. More than the main aluminum template can be poured once after the end of the assembly, if it is the same floor, like a residential building as repeat samples, the use of aluminum templates, the advantages of the offer period is significant, and the patchwork is very fine, into a wall is very Beautiful, late 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 construction template system is a quick release mold system, and a normal construction of the template can reach the first floor of the fourth or fifth day, which greatly saves the capital for the construction unit (currently under construction in Macau - TN27 public layer construction Up to three days
2) The number of repeated applications is low, even use of low cost, aluminum alloy construction aluminum formwork system chooses the aluminum alloy profiles consisting of all the kneading to do the raw material (6063-T6 or 6061-T6), a set of template specification construction can be flipped to use 300 ~ More than 50 times, even use of capital is low.
3) Convenient construction and high power: The aluminum alloy construction template system is simple and convenient to assemble, with a uniform weight of 30 KG/?. It is completely assembled by hand and does not require any mechanical equipment to annoy and assist. (A worker usually only needs a wrench or a small hammer for construction. Convenient and fast, skilled installation workers install 20 to 30 square meters per person per day (compared with wooden molds: aluminum mold installation workers only need 70 to 80% of the workers of the wood mold installation, and do not need skilled workers, only need to install the equipment before The construction staff can do a brief training.)
4) High bearing capacity: All parts of the aluminum alloy construction template system are made of aluminum alloy plates. After the system is assembled, it forms a whole structure, and the stability is very good; the bearing capacity can reach 60KN per square meter.
5) A wide range of applications: Aluminium alloy construction template suitable for the use of wall, horizontal floor, columns, beams, stairs, windows, drift board and other aspects.
6) Concrete appearance after demoulding: After the aluminum alloy construction template is demoulded, the quality of the concrete surface is flat and bright, and it can basically reach the demand of the coagulation of the facing and the clear water, and no need to carry out the concoction, which can save the expense of penalties.
7) No construction waste on site: All parts of the aluminum alloy construction template system can be reused. After the construction is demolished, there is no waste on the site. The construction environment is safe, clean and tidy.
8) Standardization and versatility: There are many norms for the construction of aluminum alloys. The non-standard version can be reduced by changing 20 to 30% of the total. cost. ,
9) High recovery value: After the aluminum alloy construction template is abolished, when the residual value of the waste disposal is high, the average cost advantage is significant (the recovery price per square meter is about 400 yuan).
10) Low-carbon emission reduction: Aluminum alloy construction template system All data can be regenerated, in line with national regulations on energy saving, environmental protection, low-carbon, and emission reduction of construction projects. Many developed countries have already ruled on construction projects and banned the use of wood stencils. They only need to use templates for reproducing materials.
11) The support system is convenient: In the traditional construction method, the template construction skills such as middle floor slabs and channels are used throughout the selection of joint brackets and cost data. On the other hand, the aluminum aluminum formwork mold support site has relatively little support (the use of an independent support spacing of 1200mm), large operating space, personnel access, data transfer and clear, on-site easy to handle.
