Technical Field

[0001] The present invention relates to the field of construction technology, and particularly relates to an inclined column steel formwork support device. Background Art

[0002] With the continuous deepening of urban construction in China, the construction industry is developing towards high quality and large scale. In high-rise comprehensive buildings and large underground structures, due to requirements in terms of functions, shapes, forces, etc., inclined column structures such as V-shaped columns are often required. However, when using inclined columns, the following problems often exist: When casting concrete inclined columns in formwork, it is necessary to control their slopes to ensure the quality and precision of construction. The traditional method is to set up a full hall scaffold as the support structure for the inclined column formwork, but this method takes up a large amount of space, has low efficiency, poor precision, and is time-consuming and laborious; the traditional construction method cannot achieve the function of arbitrarily adjusting the angle of the inclined column. Especially for large inclined columns with multiple suspended surfaces in underground projects with narrow construction environments, the traditional steel formwork and steel formwork supports cannot solve the above problems, so it will also affect the construction progress.

[0003] To solve the above problems, an inclined column steel formwork support device is needed. Summary of the Invention

Moreover, this support structure is small in volume, suitable for narrow construction environments such as underground areas, has reliable support, can be reused, and has wide applicability.

[0006] Further, the jacking adjustment plate includes a jacking plate body hinged to the support base and a limiting rib plate protruding upward along the jacking plate body. The limiting rib plate is an arc-shaped structure and is used to support and limit the inclined column steel formwork.

[0007] Further, the jacking plate body forms two jacking arms. A "U"-shaped slot is formed between the two jacking arms. The two jacking arms have the same structure and are symmetrically arranged with respect to the "U"-shaped slot. The lower surface of the jacking arm is provided with a positioning groove.

[0008] Further, a hydraulic jacking mechanism is installed on the support base. An installation opening for installing the hydraulic jacking mechanism is formed on the support base.
