However, the suspended formwork construction is easily affected by various factors such as the construction environment, the skills of workers, and the quality of materials, and quality problems such as non-compact concrete and uneven surface are likely to occur. The construction of the suspended formwork for the hole needs to be carried out at a high altitude, with great operation difficulty and requires experienced workers to operate. At the same time, due to the relatively complex structure of the suspended formwork, both the installation and disassembly require a large amount of manpower and time, with problems such as great construction difficulty, poor stability, and high safety risks. Therefore, a formwork support device for reserved holes at the corners of building floors is proposed to solve the above problems. Content of the Utility Model

[0006] In some embodiments, there are two flat supports, and the difference in the vertical height between one flat support and the other flat support is the same as the thickness of the wooden formwork.

[0007] In some embodiments, the wooden formwork is arranged on the flat support with a lower vertical height. The lower surface of the wooden formwork is attached to the flat support, the upper surface of the wooden formwork is attached to the reserved hole at the upper floor slab, and the area of the wooden formwork is larger than the area of the reserved hole.
