New Material Application Knowledge: Aluminum Alloy Formwork in The Construction Of The Application

1.1 introduction to aluminum alloy formwork. Aluminum alloy formwork is mainly composed of formwork system, fastening system, supporting structure system and accessory system. The utility model has the characteristics of high strength requirement and large thickness. When the aluminum alloy and its skeleton after welding, will become the highest strength and stiffness effect of the metal template

1.2 aluminum alloy template advantages.

1.2.1 aluminum alloy formwork has its own small weight, usually about 20kg, can effectively enhance the use of construction efficiency. For example, the pin or wedge acting on the connecting system, because of its convenient construction characteristics, so, in actual operation, only manual handling, can save equipment investment, improve construction efficiency

1.2.2The control effect of the convenience of the support system is outstanding. Although there are not many supporting rods in aluminum alloy formwork, the maximum distance of independent support is in the range of 1200mm × 1300mm, which can provide a more relaxed space environment for the actual construction of high-rise buildings

1.2.3Has the high strength, the stability and the bearing capacity. After installation, the overall structure is relatively stable, bearing capacity can reach 70 kw/m2

1.2.4Has the high strength, the stability and the bearing capacity. After installation, the overall structure is relatively stable, bearing capacity can reach 70 kw/m2;

1.2.5The template can be removed to maintain a good surface effect. The template is installed and connected tightly, the gap is controlled strictly, the effect after construction is remarkable and the size is accurate. After the demolition can ensure the smooth surface effect, to meet the construction design requirements;

1.2.6The utility model can be repeatedly used, and the average construction cost is reduced. Under normal operation, a set of aluminum alloy template can be used more than 400 times, the more times it is reused, the lower the actual cost;

1.2.7Is advantageous to the construction site civilization construction, enhances the security. After completion of construction, the site environment is well, no garbage and sundries, and aluminum alloy formwork is non-combustible material, effectively prevent the occurrence of fire;

1.2.8High recovery rate. The aluminum alloy template achieves the service life, carries on the scrap time, has the high processing value;

1.2.9In favor of reducing energy consumption. Because of the nature of its main materials for renewable materials, so in line with the requirements of energy-saving emission reduction, followed the basic policy of green environmental protection.

1.3 disadvantages of aluminum alloy templates.

1.3.1 because the number of buildings more than 25 storeys, can make the economic effect of aluminum template play out, otherwise, the cost is not low anti-high;

1.3.2 aluminum template production, to strictly follow the established construction drawings, because, once confirmed, can not be changed, otherwise it will lead to template modification costs of additional expenditure;

1.3.3such template first use period, the cost is relatively high.
