[0002] With the rapid development of urbanization, urban buildings are becoming increasingly dense, which puts higher requirements on the construction of underground pipe corridors in municipal engineering. The construction and application of caissons are also more common. The geological conditions in some caissons are complex. When using traditional scaffolding for construction, the scaffolding is erected at a high height, and the foundation also needs to be hardened. Some companies will use the pre-buried beam caisson internal frame construction method in engineering caisson construction, which optimizes the scaffolding erection method inside the caisson, reduces the scaffolding erection height, and shortens the caisson scaffolding construction period. However, it is difficult to connect and fix the I-beam with its upper steel pipe scaffolding, and there are certain safety risks. How to quickly connect and fix the scaffolding and I-beam while ensuring safety and firmness is a problem that needs to be solved now. Utility Model Content

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] Example 1

[0019] like Figure 1 , Figure 2 As shown, a scaffolding installation fixing structure on the surface of an I-beam in a steel frame structure in a caisson comprises: a plurality of fixing mechanisms 3 fixed on an I-beam 2 in a steel frame structure in a caisson 1, wherein the I-beam 2 in the steel frame structure is fixedly connected to the inner side of the caisson 1 through the fixing mechanism 3, and the bottom of the scaffolding can be fixed in a limited position. In this embodiment, the fixing mechanism 3 of the following structure is used to fix the bottom of the scaffolding in a limited position;

[0020] The fixing mechanism 3 includes: a limit block 310 and a welding plate 320. The limit block 310 is located between two I-beams 2 arranged side by side, and the two ends of the limit block 310 extend into the abdominal cavity of the two I-beams 2 respectively. The welding plate 320 is arranged above the two I-beams 2, and the two ends of the welding plate 320 are fixed to the wing plates of the two I-beams 2 respectively.

[0021] The limit block 310 and the welding plate 320 are connected by a connecting column 330, and the distance between the limit block 310 and the welding plate 320 is preferably slightly larger than the thickness of the wing plate of the I-beam 2; two placement blocks 340 are fixed side by side on the welding plate 320, and a limit groove 360 ​​for limiting the bottom of the scaffolding is formed between the two placement blocks 340 on the welding plate 320.

[0022] During installation, the fixing mechanism 3 is placed vertically between the two I-beams 2, and then the limit block 310 is inserted under the wing plates of the two I-beams 2 and aligned with the abdominal cavities of the two I-beams 2, and then the fixing mechanism 3 is rotated 90° to allow the two ends of the limit block 310 to enter the abdominal cavities of the I-beams 2 respectively to achieve the limit; then the two ends of the welding plate 320 are first fixed to the wing plates of the two I-beams 2 respectively, and then the bottom of the scaffolding is placed in the limit groove 360 ​​in turn to complete the fixed and limited effect of the scaffolding. Through the fixing mechanism 3, the scaffolding and the I-beams 2 in the steel frame structure can be effectively connected and fixed, and certain restrictions are maintained on the scaffolding, thereby effectively improving the fixing efficiency of the entire scaffolding, and it is easy to disassemble and can be reused, thereby effectively improving the efficiency of the entire project, saving time and labor, and saving energy and materials.

[0023] Example 2

[0024] like Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0025] At least two through holes 342 are formed on the placement block 340 along the length direction of the I-beam 2. All through holes 342 on one of the two placement blocks 340 are coaxial with all through holes 342 on the other placement block 340. If the number of through holes 342 on the placement block 340 is two, then the two through holes 342 on one of the two placement blocks 340 are coaxial with the two through holes 342 on the other placement block 340.

[0026] The fixing mechanism 3 further includes: a plurality of bolts 350, one end of each bolt 350 is inserted into a through hole 342 on one of the two placement blocks 340 through a through hole 342 on the other placement block 340, and the bottom of the scaffold is located in the area between two adjacent bolts 350 in the limiting groove 360, and the gap between the two bolts 350 is preferably equal to the diameter of the bottom of the scaffold, so that the bottom of the scaffold can be completely restricted to prevent shaking;

[0027] After the bottom of the scaffold is placed in the limiting groove 360 ​​and is limited, the bolts 350 are quickly installed to limit and fix the bottom of the scaffold in the limiting groove 360 ​​to prevent it from falling off and improve the stability of the scaffold after being fixed.

[0028] Example 3

[0029] like Figure 2 As shown, this embodiment is a further improvement on the basis of Embodiment 1 or 2, and the details are as follows:

[0030] A placement groove 341 is formed on each placement block 340 along the width direction of the I-beam 2, and the through holes 342 on each placement block 340 are connected to the placement groove 341 thereon. The nut of the bolt 350 is located in the placement groove 341 on one of the placement blocks 340. When the bolt 350 is removed, the nut can fall directly into the placement groove 341 to prevent the nut from falling into the caisson 1.

[0031] Furthermore, the width of the limit block 310 along the length direction of the I-beam 2 is smaller than the distance between the wing plates of the two I-beams 2, which facilitates the installation of the fixing mechanism 3 between the two I-beams 2 in the early stage.

[0032] Example 4

[0033] like Figure 2 As shown, this embodiment is a further improvement on the basis of Embodiment 1, 2 or 3, and the details are as follows:

[0034] The welding plate 320 is fixed to the wing plate of the I-beam 2 by spot welding, and the fixing method is simple and has good stability.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
