In order to achieve this goal, the person in charge chooses to use sealant to connect the steel plate to realize the effective protection of the building formwork.
It can be assembled manually, or the whole can be hoisted by machinery after being assembled into pieces.
The use of colloidal materials may lead to the problem that the concrete pouring is not firm, resulting in the bad situation of joint slurry leakage during the installation of formwork.
Compared with the traditional construction technology, the construction waste generated by the prefabricated building construction is significantly reduced, which not only alleviates the environmental pollution caused by the construction, but also shortens the time spent by the construction technology.
The application scope of aluminum alloy formwork is especially applicable to concrete structure buildings with more than 25 standard floors and external walls designed as internal insulation, and the floor height should be less than 3.3m.
The construction activities shall be carried out according to the corresponding process, such as the placement of pull screw, the rubber cup and hose shall be firmly sleeved, and the connection with the formwork surfaces on both sides shall be ensured.
When the aluminum alloy formwork supporting profile steel cantilever steel pipe external scaffold is used, it is necessary to re configure the formwork on the cantilever layer, which reduces the integrity of the aluminum alloy formwork, the concrete forming effect is poor and the aluminum formwork is processed The reserved position of I-beam requires high precision, the construction is difficult and affects the construction period.
Joint review of construction drawings the construction unit, the design unit, the general contractor and the aluminum alloy formwork subcontractor shall jointly review the drawings and make corresponding image data and records.
Moreover, the outer wall is a full concrete wall structure, so it is not easy to set wall connecting parts, steel wire rope unloading and other measures, which will affect the structural construction and is not conducive to the control of construction quality and safety guarantee.
As for the use of release agent, it should be noted that the water-based release agent should be used for the last release, and the oily release agent was applied before.

8.
Light weight, less than 19kg per square meter.
The bearing capacity is large, and the aluminum alloy formwork can bear 30KN per square meter.
Strengthen the fixation of wall column formwork to ensure good contact between back edge and formwork, and reasonably control the tightness between back edge and pull screw.
The construction period is short, 2 ~ 3 times faster than the general formwork construction.
Standardized construction, high turnover times, and 300 times of normal use.
6.
After half a century of research and application, the technology has developed relatively mature, but the aluminum alloy template technology appeared relatively late in China.
3.
Ordinary people believe that the price of aluminum alloy is higher than that of wood products, and the cost of construction will also be higher than that of wood plywood.
The application of aluminum alloy formwork to carry out prefabricated building construction activities should continuously enhance the rationality and effectiveness and promote the sustainable development of the current society.
The development of this technology can effectively make up for the shortage of wooden formwork.
Conduct in-depth docking with door and window units, railing units and water and electricity installation units to ensure that each detail can be reasonably connected, and timely determine with the construction unit, design unit and supervision unit.
5.
The drawing optimization project department shall cooperate with the design department of aluminum alloy formwork subcontractor to optimize the original construction drawings.
Therefore, the development of aluminum alloy template technology in China is relatively backward.
Advantages of aluminum alloy formwork 1.
climbing frame), which can effectively reduce the holes left in the structure and organize the interspersed construction of various processes (the exterior wall doors and windows, railings, putty, etc.
High recycling value.
Ensure that the building formwork is firmly connected with each other during construction.
Therefore, it is not recommended to use section steel cantilever steel pipe external scaffold.
Aluminum alloy building formwork has high residual value and obvious cost sharing advantage.
The assembly construction method has emerged in the construction, so as to better meet the needs of social progress.
The use of prefabricated building construction means is in line with the green construction concept, and aluminum alloy formwork is a typical representative.
Use of aluminum alloy building formwork, wall formwork, horizontal floor slab, column, beam, climbing formwork, etc.
Once changed, it will have a great impact on the construction period and cost.
The contract shall be signed in accordance with the company’s aluminum alloy formwork subcontract model, supplemented with corresponding special terms, timely signed the contract and paid the advance payment.
Consideration should be given to all aspects in order to reduce the possibility of construction problems.
are constructed in the reverse method from bottom to top with the main body), so as to avoid plastering on the exterior wall, improve the project quality, speed up the construction period and improve the image of the construction site.
However, in fact, the cost of aluminum alloy formwork is lower than that of wood products.
At this time, the appearance and quality of the building may be adversely affected..
7.
After the structure, architectural design and delivery standards are determined by all units, they cannot be modified or adjusted.
The construction is convenient, and the aluminum alloy building formwork is easy to assemble.
Precautions for the construction of fabricated formwork there are many precautions for the construction of fabricated formwork.
Reduce the possibility of construction problems and effectively reduce the construction cost.
4.
2.
Aluminum alloy formwork subcontracting inspection shall select large-scale and experienced aluminum alloy formwork manufacturers, and aluminum alloy formwork units that have cooperated with the construction unit of the proposed project shall be given priority.
The concrete surface quality is flat and smooth, which can achieve the effect of facing or fair faced concrete.
Aluminum alloy building formwork has high strength, high precision and few slab joints.
If the construction process is not well controlled in the production process, the quality of components will not be guaranteed.
Focus on the manufacturer’s strength, aluminum material, plate forming, production process, design optimization ability, processing quality, supply capacity, measured actual quantity qualification rate of concrete forming and technical service, understand its production and processing cycle, product price, recovery residual value rate, accessory supporting form, and consider the transportation distance.
The aluminum alloy template with low production cost first appeared in the United States.
Inspect the factories and projects under construction of aluminum alloy formwork manufacturers.
Wide range of applications.
The form of supporting external frame is especially suitable for cooperating with the attached lifting scaffold (i.e.
Fabricated components can effectively avoid this deficiency and produce components according to the standard requirements, which ensures the production quality of components to a great extent.
With the rapid economic development, the industry innovation has been strongly driven.
In terms of traditional construction activities, there are relatively high professional requirements for constructors.
