[0002] Construction formwork refers to temporary or permanent formwork used in construction projects to support, bear load, and shape concrete structures. Its main function is to shape the concrete structure and maintain its shape after pouring until the concrete hardens and reaches sufficient strength. Formwork is an indispensable infrastructure in construction, widely used in the construction of floor slabs, beams, columns, walls, and other structures. Construction formwork is the core of concrete shaping during the pouring process, supporting and fixing the concrete to ensure it maintains the required shape and dimensions during hardening. Together with the support device, the formwork forms a stable support structure capable of withstanding the weight and pressure of the concrete during pouring. During on-site construction, to ensure ease of use, the support device is generally a one-piece welded steel component. Due to different construction needs, the installation height of construction formwork varies. Ordinary steel components cannot be adjusted in length, requiring the selection of steel components of different lengths, which is inconvenient. To address the aforementioned issues, this application proposes an adjustable building formwork support device. Utility Model Content

After the base plate 31 is installed, the bolts in the third mounting hole 310 will limit the slider 33 to prevent the slider 33 from disengaging from the slide groove 32.

[0032] The working principle and usage process of this utility model are as follows: First, use bolts to fix the base plate 31 to the ground or a designated position in the third mounting hole 310. The third mounting hole 310 facilitates the installation of the base plate 31 by the operator, thus facilitating the installation of the device. After the base plate 31 is installed, the bolts in the third mounting hole 310 limit the slider 33, preventing it from dislodging from the slide groove 32. Then, install the mounting plate 1, placing it on the slider 33. Next, use bolts to fix the slider 33 to the mounting plate 1, allowing the mounting plate 1 to move along the slide groove 32 to adjust the position of the support plate 4. This adjustment does not require disassembling the base plate 31, allowing operators to adjust the position of the support plate 4 according to on-site construction needs. After adjusting the position of the mounting plate 1, bolts can be used to pass through the second mounting hole 39 and the second threaded hole 38 to fix the mounting plate 1, preventing...

By removing the bolts in the second connecting hole 43, the connecting plate 42 can be de-fixed to the circular plate 29, allowing workers to replace the support plate 4 with a suitable size according to the size of the building template and construction needs, ensuring the stability of the support. When the support height needs to be adjusted, the second threaded ring 213 can be rotated first, causing the second threaded ring 213 to drive the second connecting rod 212 to move, which in turn drives the circular plate 29 to move, and the circular plate 29 to move the moving column 26 together, adjusting the height of the support plate 4 at the top of the moving column 26. When a higher position needs to be supported, the threaded rod 214 can be rotated, causing the threaded rod 214 to drive the first threaded ring 211 to move, which in turn drives the first connecting rod 210 to move the annular plate 28 together, and the annular plate 28 to move the second sleeve 23 together, preventing the moving column 26 from detaching from the second sleeve 23 and improving the stability of the support.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
