Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a floor slab construction support device. Background Technology

[0002] In building construction, the construction of cast-in-place floor slabs requires the use of support devices to support the bottom of the floor slab formwork. The initial support devices are usually made of wooden rods or metal pipes, and their height is not adjustable, so they need to be made according to different support height requirements.

[0003] In the prior art, Chinese utility model patent document CN217812558U discloses a precast floor slab support device. In this device, independent columns are placed vertically at designated locations according to construction requirements. A triangular stabilizer secures the position of the independent columns, improving their installation stability. An independent top support is installed at the top of the independent column, and an I-beam is placed in a groove. A fixing mechanism secures the I-beam within the groove, improving the connection stability between the I-beam and the independent top support, and thus enhancing the installation stability of the precast floor slab. While the fixing mechanism improves the connection stability between the I-beam and the independent top support, the I-beam requires a through hole matching the fixing component for connection. However, currently used I-beams typically do not have pre-drilled openings. Therefore, to use this support device, the I-beam needs to be drilled, which not only increases labor time but also affects the load-bearing capacity of the I-beam.

[0004] Therefore, it is necessary to design a floor slab construction support device that can improve the stability of the connection with the I-beam without affecting the load-bearing capacity of the I-beam to solve the current technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a floor slab construction support device that improves the stability of the connection between the slab and the I-beam without affecting the load-bearing capacity of the I-beam.
