Non-standard layer aluminum alloy formwork square wood composite structure of high-rise buildings

technical field

The utility model relates to a formwork support structure, in particular to a non-standard layer aluminum alloy formwork square-wood composite structure of a high-rise building.

Background technique

At present, more and more construction companies choose to use the aluminum alloy formwork support system in the construction of the main structure of high-rise residential buildings. It is not easy to explode, and it is energy-saving and environmentally friendly, and will not cause on-site pollution. However, due to the relatively high unit price per square meter of aluminum formwork and the relatively fixed specifications, it is generally only used on the standard floor. For the top floor of high-rise residential buildings, the floor height is generally about 10cm higher than the standard floor, and the standard layer aluminum formwork cannot be directly used for construction. . The normal standard size aluminum alloy formwork support system has a turnover of more than 200 times. Considering the cost of the formwork, most of the aluminum alloy formwork currently used on the construction site is leased by the manufacturer. According to the conventional cost calculation, the turnover of the aluminum alloy formwork on site exceeds 18 times is relatively economical, and the number of formwork turnover increases, which can save construction costs and reduce the construction cost of aluminum alloy formwork. If the lessor is required to specially make a set of non-standard layer aluminum alloy formwork, only the top layer of the high-rise building will be used for the last time, which obviously wastes the rent, and will affect the construction period and increase the construction cost.

Therefore, in order to solve the above problems, the technicians considered the gap between the aluminum alloy formwork and the top form of the standard height to be supplemented by square wood, and the overall pouring of the non-standard layer by using the combination of aluminum alloy formwork and square wood, as well as saving Construction cost and shorten construction period.

CN 206928651 U discloses a formwork connection structure at the intersection of a wall aluminum formwork and a roof wooden formwork. In the scheme, it is disclosed that a wall aluminum formwork and a top wooden formwork are used as a support system, and between the wall aluminum formwork and the top wooden formwork There is a vertical wooden formwork in the space between the vertical wooden formwork and the wooden square on the front of the vertical wooden formwork. Fastened with spikes. The top plate of this scheme uses the design scheme of wood formwork, and the tie bolt assembly is only to fix the square wood and aluminum alloy formwork, the square wood and the vertical wood formwork are fixed by long nails, and the vertical wood formwork and the roof wood formwork are fixed between It is fixed by long nails, that is to say, the top plate wooden formwork and the aluminum alloy formwork are indirectly connected, and are easily deformed by force. In addition, this fixing method is complicated to operate, requiring a lot of manpower to drive the nails into the square wood one by one. After use, the nails need to be pulled out to achieve turnover, which is inconvenient to use and low in efficiency.

Finally, steel bar binding and concrete pouring are carried out according to the standard layer, which saves the time for the use of wood formwork and the time for setting up the formwork, and speeds up the construction progress. , saving the construction period. After the reinforcement is completed, the integrity is good, and no construction joints are left after the concrete pouring is completed, so as to avoid the occurrence of hidden leakage in the later stage.

The non-standard layer on the top layer is constructed with aluminum alloy formwork + square wood support system. Except for the parts such as the wall, top plate, and exterior wall shape that are higher than the local wall position of the standard layer, most of the contact surfaces of the formwork are still aluminum alloy formwork, and the surface of the formwork is still made of aluminum alloy formwork. Smooth, high overall rigidity, high overall formwork precision control, smooth surface after concrete pouring, no misalignment phenomenon, component size and position meet the design requirements, in addition, some external wall modeling components are supported by aluminum alloy formwork The system is completed in one construction, which not only ensures the integrity, but also has a better look and feel than the secondary structure construction in the later stage.

An L-shaped reinforcing plate 4 is vertically arranged in the corner aluminum alloy formwork. The bending resistance of the corner aluminum alloy formwork can be enhanced by the L-shaped reinforcing plate 4, so as to prevent deformation at the corner and affect the concrete structure.

Specifically, during on-site construction, the standard layer aluminum alloy formwork is first used to support the formwork of the wall and beam parts. Beam part) and the lower formwork are supplemented by adding square wood corresponding to the height and width of the section. The outer surface of the square wood is fixed at intervals of 600mm by the pull screw to ensure that the square wood and the aluminum alloy formwork are firmly fixed and prevent the concrete pouring process. In the middle, the mold expansion phenomenon occurs due to the lateral pressure of the concrete.

When the concrete is poured, the vibrator is used to fully vibrate, and the wall and roof are poured at one time, which not only ensures the integrity of the concrete structure, improves the structural safety, but also does not produce construction joints, which avoids the use of the top room by the owner in the later period. A leakage problem occurs during the process, which affects the use function.
