[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] like Figure 1-4 As shown, an adjustable upright fixing device for a cantilever scaffolding comprises a support member 2, a positioning tube 3 and a sliding member 7. The support member 2 and the sliding member 7 are both in contact with the steel section 1. The positioning tube 3 is fixedly installed on the upper surface of the support member 2. The sliding member 7 is sleeved on the support member 2 and slides along the support member 2, so that the sliding distance of the sliding member 7 on the support member 2 can be adjusted according to the size of the steel section. When the support member 2 and the sliding member 7 are in contact with the steel section, they are fixedly connected by a building lead screw. There are no holes or grooves on the support member and the sliding member. The structure is simple, the structural strength is high, the manufacturing cost is low, and the turnover will not be affected by the adhesion of debris during use.

[0025] like Figure 2 As shown, the support member 2 includes a support plate 201, a vertical plate 202 and a first horizontal plate 203, one end of the support plate 201 is welded to the top end of the vertical plate 202, and the bottom end of the vertical plate 202 is welded to one end of the first horizontal plate 203;

[0026] The lower surface of the support plate 201 abuts against the upper surface of the flange plate of the steel section 1 , the inner side wall of the vertical plate 202 abuts against the side wall of the flange plate of the steel section 1 , and the upper surface of the first horizontal plate 203 abuts against the lower surface of the flange plate of the steel section 1 .

[0027] Specifically, the positioning tube 3 is vertically welded to the upper surface of the support plate 201 along the axial direction, and is used for inserting the vertical poles of the scaffolding.

[0028] like Figure 3-4 As shown, the sliding member 7 includes a channel steel 701 and a second horizontal plate 702, and the second horizontal plate 702 is welded at the opening of the channel steel 701;

[0029] The inner wall of the channel steel 701 abuts against the support plate 201 and slides along the support plate 201;

[0030] The upper surface of the second horizontal plate 702 abuts against the lower surface of the flange plate of the steel section 1 .

[0031] Specifically, it also includes a first connecting ear plate 5 and a second connecting ear plate 6. The first connecting ear plate 5 is welded to the upper surface of the support plate 201, and the second connecting ear plate 6 is welded to the upper surface of the channel steel 701. The opening diameters of the first connecting ear plate and the second connecting ear plate are equal and are in the same axial direction.

[0032] Specifically, the first connecting ear plate 5 and the second connecting ear plate 6 are connected by a building screw 4, and nuts are connected at both ends of the building screw 4, and the nuts are respectively abutted against the surfaces of the first connecting ear plate 5 and the second connecting ear plate 6 that are away from each other. The support and the sliding member are fixed by the building screw. When the nuts on both ends of the building screw are in a tightened state, the support and the sliding member can be pulled to abut against the flange plate of the steel section. When the nuts on both ends of the building screw are in a loosened state, a gap is left between the support and the sliding member between the steel section to facilitate position adjustment. Furthermore, a protective tube can be wrapped around the outside of the building screw to prevent concrete or debris from falling and affecting the building screw. Even if concrete or debris falls directly on the building screw, the concrete on the building screw is easy to clean, and the impact on the separation of the support and the sliding member is small, which is convenient for turnover.

[0033] The use process of the utility model is as follows:

[0034] First, one end of the support plate connected with the vertical plate and the first horizontal plate is brought into contact with the flange plate of the steel section, and the position of the support plate is preliminarily adjusted;

[0035] Secondly, after the initial position adjustment is completed, the sliding piece is installed from the other end of the support plate;

[0036] Then, the construction screw is passed through the first and second connecting ear plates, and the nuts at both ends of the construction screw are properly tightened, and the support member and the sliding member are operated to slide on the steel section to achieve precise positioning. After the precise positioning is completed, the nuts at both ends of the construction screw are tightened so that the nuts are respectively abutted against the surfaces of the first connecting ear plate and the second connecting ear plate that are away from each other, thereby completing the fixing operation;

[0037] Finally, insert the scaffolding poles onto the positioning tubes.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
