[0003] After retrieval, the Chinese patent publication number is: CN220978824U, an adjustable concrete formwork support device, which relates to the field of concrete formwork support. It includes a plurality of reinforcing plates arranged around the outside of the formwork. Each of the plurality of reinforcing plates includes a connecting plate and an adjusting plate. A through groove is opened on the adjusting plate. One of the connecting plates passes through the through groove of the adjacent adjusting plate. A reinforcing component for attaching the reinforcing plate tightly to the outside of the formwork is also provided between the adjacent connecting plate and the adjusting plate. This application has the effects of conveniently reinforcing and supporting the concrete formwork and having a wide adaptability range for reinforcement installation. However, when adjusting the formwork size, this device needs to manually rotate the screw sleeve for multiple turns and drive the relative displacement of the push rod to make the reinforcing plate close to the formwork.

[0045] Working principle: The fixed plate 3 is firmly fixed to the bottom plate 1 by welding, providing a stable base for the entire support device. The moving plate 6 slides horizontally in the through hole 4, realizing the rapid adjustment of the width of the concrete formwork. The one-way rack 7 on the moving plate 6 meshes with the one-way teeth 10 in the tooth block 9 on the left side of the fixed plate 3, ensuring that the moving plate 6 can maintain a stable position during the sliding process and preventing movement caused by external forces. The sliding connection of the T-shaped slider 8 in the T-shaped groove 5 provides vertical guidance and support for the moving plate 6, ensuring the smoothness and stability of its sliding. At the same time, the design of the T-shaped slider 8 and the T-shaped groove 5 also increases the overall strength of the device and improves its load-bearing capacity. Leakage holes 11 are opened on the top walls of both the fixed plate 3 and the moving plate 6. These holes can effectively drain excess liquid during the concrete pouring process, avoiding problems such as formwork deformation or loosening of the support structure caused by water accumulation.

[0046] Moreover, the water storage tank 201 is connected to the water pump 203 through the supply pipe 202. As the water pump 203 operates, the water source flows into the shunt pipe 204 through the supply pipe 202. The shunt pipe 204 enables the water source to be evenly distributed to each spray pipe 205. These spray pipes 205 are equidistantly installed on the top wall of the shunt pipe 204, ensuring the even spraying of the water source. At the front end of each spray pipe 205, an atomizing nozzle 206 is connected. These atomizing nozzles 206 will spray the water source on the surface of the concrete formwork in an atomized form. The atomized water source can better contact the concrete and effectively provide moisture for the concrete, thereby preventing the concrete from cracking due to excessive drying and ensuring that the concrete is always in the best state.
