01 when designing aluminum alloy formwork, the owner’s structural drawings and architectural drawings must be very accurate.

That is, first remove the plate mold, starting from the keel, remove the pin, remove the plate mold, then remove the C groove, and then remove the column mold.

Flat End Socket

Similarly, aluminum formwork also has certain limitations: it must be used in buildings with a large number of standard floors to reduce the use cost (buildings with less than 30 floors in a single building are not considered, except for those constructed by stages).

The aluminum formwork system is simple and convenient to assemble, with an average weight of about 20kg.

The purchase price of a set of templates is shared equally, which saves a lot of costs compared with traditional templates.

The normal construction of a set of formwork can reach one floor in four to five days, and the assembly line construction can be better carried out, which greatly improves the construction progress and saves the management cost.

03 when new formwork is used, for the first and second time, due to the chemical reaction between concrete and aluminum surface, the concrete surface is flat, but some small bubbles will appear.

According to the theoretical data provided by the manufacturer, it can be reused for up to 300 times.

The normal construction of a set of formwork can reach one floor in four to five days, and the assembly line construction can be better carried out, which greatly improves the construction progress and saves the management cost.

The aluminum formwork system is a quick formwork removal system.

05 less joints, high precision, good concrete surface effect after formwork removal.

Based on the above analysis, it is more economical to purchase aluminum formwork for 60 times or more than to rent aluminum formwork.

Moreover, the system design is simple, and the workers’ hands-on speed and formwork turnover speed are very fast.

The support system is simple in structure and easy to remove, so the whole construction environment is safe, clean and tidy.

The following technical advantages can be particularly reflected in areas with high urbanization degree: the construction period is short.

During the whole process, the supporting parts shall not be removed..

02 the cost of large steel formwork is lower than that of aluminum formwork, but the large steel formwork has higher requirements for machinery and labor, and the construction period is relatively long.

If the structural shape changes, it needs to be returned to the factory for reprocessing.

1、 Which is more economical to rent or purchase aluminum alloy formwork? Aluminum alloy formwork can be rented or purchased.

The first supported formwork shall be removed later, and the second supported formwork shall be removed first.

02 the one-time investment is high (for a 30 story building with a single floor area of 900m2, for example, a one-time investment of 3.564 million yuan is invested in the purchase).

It is completely handled and assembled manually without the assistance of any mechanical equipment.

08 high aluminum formwork with recycling value has many specifications, which can be assembled with plates of different specifications according to the project; When the used formwork is reconstructed into a new building, only about 20 non-standard plates need to be replaced, which can reduce the cost.

Therefore, the aluminum formwork system is suitable for super high-rise buildings or multi-storey buildings and villas with a high degree of standardization.

0303 introduction to aluminum formwork construction process installation of aluminum formwork: removal of aluminum formwork: the removal sequence is different from that of general wood formwork.

06 there is little construction waste on site, the support system is simple, and all accessories of the aluminum formwork system can be reused.

05 comparison of characteristics of aluminum formwork and steel formwork: comparison of one-time investment costs of aluminum formwork, steel formwork and wood formwork: Note: it is considered as a 30 story building with a single floor area of 900m2.

The aluminum formwork system is a quick formwork removal system.

Each time, it is calculated at a return rate of 30%, and the return department needs an additional processing fee of 700 yuan / ㎡.

01 the aluminum formwork system adopts the aluminum alloy profile formed by overall extrusion as the raw material, and a set of formwork can be overturned and used more than 300 times for standardized construction.

10.

After the aluminum formwork is processed, it can not be modified on site.

2、 Cost comparison and summary analysis of aluminum formwork, wood formwork and large steel formwork: if aluminum alloy formwork is purchased, a single project (with the same structural form) can be used for 60 times, which is more economical than wood formwork in terms of cost (including waste disposal after aluminum alloy formwork is not used).

Cost analysis of aluminum formwork construction key points and combined use method of cast construction 01 characteristics of aluminum formwork components of aluminum formwork system need to be designed according to floor characteristics, which requires high ability of design technicians.

Comparison of aluminum formwork, steel formwork and wood formwork support system: 02 aluminum formwork cost analysis mainly analyzes from two aspects: which is more economical to rent or purchase aluminum formwork; Cost comparison of aluminum formwork, wood formwork and large steel formwork.

04 aluminum formwork is not used for basement formwork temporarily.

In addition, it can better carry out assembly line construction, greatly improve the construction progress and save management costs.

01 if different items of aluminum alloy formwork are purchased for continuous turnover and need to be returned to the factory, 90 times of turnover of aluminum alloy formwork can be the same as the cost of wood formwork (including waste disposal after aluminum alloy formwork is not used).

03 with good stability and high bearing capacity, the bearing capacity of most aluminum formwork systems can reach 60kn per square meter, which is enough to meet the bearing capacity requirements of most residential buildings.

(wood formwork can be cut freely on the project).

Skilled installation workers can install 20-30 square meters per person per day, greatly saving labor costs.

07 standard and universal aluminum formwork system is a quick formwork removal system.

After the formwork removal, there is no waste on site.

Even if the early-stage capital investment and storage costs of aluminum formwork are considered, the turnover of 90 times or more is more economical than the rental costs.

09 all materials of low carbon emission reduction aluminum formwork system are renewable materials, which comply with the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects.

02 convenient construction and high efficiency.

The purchase price is about 1200 yuan / ㎡, and the residual value is about 230 yuan / ㎡.

The normal construction of a set of formwork can reach one floor in four to five days.

About 80% of the modules in the aluminum formwork system can be recycled in multiple projects, while the remaining 20% can only be recycled in a class of standard floors.

04 scope of application: the wide aluminum formwork is suitable for the use of walls, horizontal floors, columns, beams, stairs, windowsills, floating plates and other positions, and is also useful for the formwork support of secondary structures such as ring beams, structural columns and inverted sill.
