Aluminum alloy template for the first time in Tianshui area

There is a construction project in Huatian Science and Technology Park at the west exit of Tianshui City. Although it is just an ordinary high-rise apartment building, it has attracted wide attention in the Tianshui construction industry because the construction company Gansu Jiantou Bajian Group is in Tianshui District. The first use of aluminum alloy templates has a significant effect on building quality and perception.

Huatian Science and Technology Talent Apartment Project has 26 floors above the ground, 1 underground floor, a total construction area of ​​20,800 square meters, and a construction cost of 41.40 million yuan. The entire building is a two-elevator apartment. The quality goal is to ensure the Maiji Award and the Gansu Construction Investment Cup to create a flying award.

In the construction of the main body, the eight-building group took the lead in the introduction of aluminum alloy formwork construction technology in Tianshui City. Before that, they had sent personnel to manufacturers and foreign construction projects to inspect and observe, and finally determined the introduction and application of this new process.

According to Wang Zhizhou, deputy manager of the eight-building group company, the aluminum alloy formwork was specially designed according to the design of the construction, and a contract for production and installation was signed with the manufacturer. The manufacturer sent someone to the site to install it, and the manufacturer recovered the work after completion. The use of aluminum alloy formwork in the standard floor clean house has obvious advantages.

Compared with the traditional wooden formwork, the aluminum alloy formwork is connected by screws to the components without the need for pipe or fasteners. It has good stability and is safe and convenient. The strength of the plate and the special wall-penetrating wire do not have to worry about excessive vibration, and the expansion mold and deformation occur. The chance is very small and the concrete quality is guaranteed. After actual measurement, the yin and yang angle error does not exceed 3 mm, the verticality of the external wall does not exceed 5 mm, and some of the internal walls even reach 2 mm or less, far below the national standard; the walls are empty, the honeycomb is pitted, and the staircase construction is completely closed. Eliminating the deformation damage, the stairs slope surface without molding. When Tianshui City's construction administrative department organized the industry to observe and study, it was evaluated: “The wall surface is of good quality, verticality and flatness are all relatively good, and the yin and yang corners are square, meeting the national regulatory requirements.”

Since the aluminum alloy formwork is transported in bulk, and the site number is assembled, each component can't be carried out in the subsequent process. Therefore, the first floor is installed slowly, the rear can be much faster, the total construction period is reduced, and the main construction can ensure the 5th floor. .

In terms of cost, the aluminum alloy formwork is 20% more expensive than the wood formwork, but since the inner wall does not require plastering, it should be calculated at the same level. At the same time, the lighter self-respect, which reduces the labor intensity of workers, is welcomed by the workers. They reflected: "The concrete is not afraid of leakage, no floor ash, and there is little rubbish on the floor."

Of course, the aluminum alloy template also has its disadvantages, which are greatly affected by weather conditions. When the temperature is low, it does not absorb water. When the outdoor sunlight is in direct sunlight, the metal temperature is too high; once the template is ordered, the project cannot have large design changes. But these can be completely overcome compared to their advantages.

During the construction, Huatian Science and Technology Talent Apartment project has received more than 30 companies to observe and learn. The colleagues have expressed that: “The quality of concrete is really good, aluminum alloy template is worth promoting.” In the big inspection of the eight construction group in the second half of this year, Hua Tian Technology Talent Apartment project scored the first, setting a benchmark.
