Technical Introduction
1. Introduction and application background of aluminum formwork system
-The effect of construction quality improvement (the quality of design and production determines the quality of construction)
-Effect of reducing construction cost
-Improve the effect of on-site construction (reduce labor and improve the construction ability of non-professional personnel)
-Improvement effect of construction site environment
-Construct a safe construction site (prevent construction site accidents)
2. Construction quality improvement effect (the quality of design and production determines the quality of construction)
-- Maintain the precision of the frame with high-quality design and precise processing
-Vertical and horizontal accuracy
-- prevent the phenomenon of wall plate bulging and floor sagging during frame construction
-Maintain the consistency of the quality of the frame (to prevent the site builder from changing it arbitrarily)
-- Prevent the occurrence of defects and cracks
3. The effect of reducing construction costs.
-- shorten the construction period
-Reduce the cost of opening and gap treatment and wall decoration
-Reduce scaffolding, bracing and related installation and handling costs
-- Reduce the cost of construction waste generation and site cleaning.
-Reduce the cost of auxiliary construction.
4. Improve the effect of on-site construction (reduce labor and improve the construction ability of non-professional personnel)
-- Safe construction period (4-6 days/floor)
-- Improve the construction ability of non-professional personnel
-- Do a good job in the inspection of drawings in advance to improve the efficiency of auxiliary construction.
-Accuracy of the location of building landfills (cables, equipment)
5. Improvement effect of construction site environment
-- Recycling of materials (waste reduction; low-carbon environmental protection, energy conservation and emission reduction, in line with national green construction regulations)
-Clean site management
6. Build a safe construction site (to prevent accidents on the construction site)
-- Ensure the distance between supports to ensure sufficient working space
-- The application of accurate structural calculation system can ensure the safety of construction.
-Reduce the incidence of accidents during site cleaning
7. Summary of Aluminum Formwork System
1. Aluminum template material and composition
⑴. Definition: Aluminum formwork system is a formwork system that uses aluminum alloy extruded profiles processed into aluminum formwork to maximize the construction efficiency of the construction site.
(2). Material: A6061-T6
Features:
Project Unit 6061-T6
Specific gravity Kg/cm3 2.71
Tensile strength Rm/MPa >260MPa
Allowable amount shall be 1.250 Kgf/cm2
Zero coefficient Kgf/cm2 7.0*105
Composition:
① Wall slab ② Floor slab, side keel, middle keel and support head ③ Floor slab connectors and supports ④ Corner and beam side plate
Installation and price
| Cost performance of aluminum alloy formwork and wooden formwork | ||
| Aluminum alloy formwork | Wooden formwork | |
| Price |
Current price is 1800 yuan/m2 |
45 yuan/m2 (including labor and materials) |
| Number of uses | 300-500 times (A set of formwork can be flipped and reused according to specifications) |
3-7 times (Note: When replacing formwork, consider the labor and time to remove the old wooden formwork) Labor and manpower) |
| From the above comparison, it can be seen that the usage rate of aluminum formwork is about 60 times that of wooden formwork, From this, we can calculate the actual price of aluminum alloy formwork compared to wooden formwork: |
||
| For a 30-story building, the actual aluminum price is 1800 ÷ 60 = 30 yuan/m2. Adding the labor installation fee of 200 yuan/m2, the actual price is only 52 yuan/m2, not including the recycling of waste aluminum (400 yuan/m2), which is actually lower than the price of wooden formwork. |
