Advantages of aluminium alloy formwork:
1. Short construction period: aluminum alloy architectural template system for quick removal system and a template of normal construction can reach three or four days a, greatly reduce the construction cost of the management of the unit
2. Recycle times, average and low cost: aluminum aluminum alloy construction formwork system with integral extrusion forming of aluminum alloy profiles do raw material alloy 6061-T6. A template specification construction can turn over to use more than 300-500 times, average and low cost.
3. It is convenient for construction, high efficiency: aluminum alloy architectural template system assembly is simple and convenient, the average weight 30KG/m2, completely by artificial assembling, does not need any mechanical equipment to assist (construction workers usually only need a spanner or a small hammer, convenient), skilled installation workers per person per day can be installed 20-30 square meters (compared with wood, aluminum mold installation workers need only 70-80% of wooden model of the installation workers, and removes the need for skilled workers, just prior to installation of construction personnel were simple training can).
4. The stability and bearing force: aluminum alloy architectural template system all parts of the assembly of the aluminum alloy plate and, after the completion of the assembly system, forming a whole frame, stability is very good; bearing capacity per square metre 60KN.
5 wide range of application: aluminum alloy construction formwork is suitable for the use of wall, level floor, column, beam, stair, window sill, floating board and so on.
6. After the removal effect of the surface of the concrete: aluminum alloy architectural template removal, surface quality of concrete is smooth, basically can reach concrete veneer and water requirements, without the need of plaster, saving plastering costs.
7. At the scene of the construction waste: aluminum alloy architectural template system all the components can be reused, construction after the removal, on-site any garbage, safe work environment, clean and tidy.
8. Standard, strong versatility: aluminum alloy architectural template specifications, according to the project with different specifications of the board assembly; template used rebuilt new buildings, only need to replace the 20-30% of non standard board, can reduce the cost.
9. The recovery of high value: building formwork of aluminum alloy scrap, when waste disposal of high salvage and levelized cost advantage obviously (per square metre price recovery probably around 400 yuan).
10 low carbon emission reduction: aluminum alloy construction formwork system all materials are available in raw materials, in line with national construction projects, energy conservation, environmental protection, low carbon, emission reduction requirements. Many developed countries have required construction projects are not allowed in the use of wood templates, the use of raw materials can be used in the template.
11. Support system is convenient: scaffold is widely used in the traditional construction method in floor, platform formwork construction technology, labor and material costs. While the aluminum formwork supporting pole support rod is relatively small (using an independent support spacing 1200mm one), the operation of large space, personnel access, material handling flow, the site is easy to manage.
Aluminum formwork construction of concrete structure size easy to control, butt joint precision, easy demould characteristic, to ensure that the concrete surface is smooth, bright and clean, to avoid the generate a large number of traditional wood construction defects of construction waste (sawdust, slag concrete). Aluminum alloy process template using quick dismantling system, through the artificial layer by layer to transfer, change the traditional reliance on tower crane and unloading material platform construction method, effectively speed up the construction progress, shorten the construction time limit for a project, reduces the labor intensity, improves the efficiency of the construction, construction process of green environmental protection, low carbon and energy saving, in line with the new principle of green building development.
Aluminum plate high strength, light weight, high impact strength, convenient assembly and disassembly, green environmental protection, cold tolerance and high temperature range can be normal use can be used more than 300 times, 100% can be recycled, recycling convenient, high value. The comprehensive cost savings of more than 30% wood template, the template is an ideal environmental and economical housing construction in twenty-first Century.
Aluminum formwork technology using quick dismantling system, through the artificial layer by layer to transfer, change the traditional reliance on tower crane and unloading material platform construction method, effectively speed up the construction progress, shorten the construction time limit for a project, reduces the labor intensity, improves the efficiency of construction, construction of green environmental protection, low carbon and energy saving, in line with the new principle of green building development.
At present, the common use of concrete casting in the construction industry template are steel formwork, wood template, bamboo template, plastic template and aluminum alloy template, etc.. Large mass of steel template, easy to rust, and in the concrete pouring process easy and concrete adhesive together, demoulding difficulty; wood template although light weight, but its strength low, not waterproof, easy to mildew and rot, repeated use rate is low, to the consumption of timber resources, is not conducive to the protection of the ecological environment and forest resources; the disadvantages of bamboo template is the repeated use rate is low, and can not be recovery; plastic template poor rigidity, variable type and high cost. The above template durability is not good, the standard of production is low, can not ensure the quality of concrete construction, and the construction speed is slow, the number of template turnover is low, the material consumption is large.
First, the advanced technical indicators
1, good stability, high bearing capacity, bearing capacity up to 60KN/ square meters; 2, good quality of concrete pouring, flatness and verticality index was significantly higher than that of wood template; 3, high construction efficiency, dismantling template time better than wood template; 4, floor overall pouring molding, smooth surface, completely can achieve free plastering level.
Two, outstanding economic benefits
1, can be reused for more than 500 times, the use of low cost; 2, high construction efficiency, short construction period, save time and cost; 3, the basic no need hoisting machinery, construction site clean and tidy, civilized construction management costs low; 4, high recovery value, residual aluminum template up 90% of the aluminum ingot prices.
