Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a subway bridge supporting platform for construction engineering. Background Art

[0002] To meet the convenience of daily travel and commuting for urban residents, the development of subways is accelerating, and the speed and scale of their construction are constantly expanding. As a key part of subway lines, the construction quality and safety of iron bridges are of paramount importance. However, the construction environment of subway bridges is complex and difficult, especially in urban center areas, where construction space is limited and construction conditions are harsh, which poses great challenges to the construction process. Therefore, during subway construction, the requirements for the bridge support platform are extremely high. Traditional subway bridge support platforms are generally temporary structures. Not only are the installation steps complicated, but they are also unstable and cannot be reused, resulting in resource waste and environmental pollution. To this end, we propose a subway bridge support platform for construction projects. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] Reference Figure 1-4 , a subway bridge support platform for construction engineering, comprising a support main board 1, two sets of mutually symmetrical support components 2 are fixedly mounted at the four corners of the support main board 1;

[0022] The support assembly 2 includes a base 201, a base column 202 is fixedly installed on the upper end of the base 201, a support frame 203 is fixedly installed on the upper end of the base column 202, four groups of protrusions 204 are fixedly provided around the support frame 203, a support arm 205 is movably installed on the protrusion 204, and a foot seat 206 is fixedly provided on the end of the support arm 205 away from the support frame 203, a conical fixing part 207 is fixedly provided on the foot seat 206, a hydraulic shaft 208 is fixedly provided on the upper end of the support frame 203, a telescopic column 209 is fixedly installed on the other end of the hydraulic shaft 208, the other end of the telescopic column 209 is fixedly connected to a connecting plate 210, and the other end of the connecting plate 210 abuts against the bottom of the support main board 1.

[0023] Through the combination of the base 201, the base column 202, the support frame 203, the protrusion 204, the support arm 205, the foot 206 and the conical fixing part 207, the device forms a stable support structure. The movable installation of the protrusion 204 and the support arm 205 allows the support arm 205 to adjust its angle within a certain range to adapt to different construction environments and bridge structures. The setting of the hydraulic shaft 208 and the telescopic column 209 can simply and quickly adjust the height of the support main board 1, facilitate construction operations, and also enable the device to adapt to different terrains. Even in uneven areas, the height of the telescopic column 209 can be changed by adjusting the hydraulic shaft 208, so that the support main board 1 remains flat.

[0024] As an optional embodiment, a mounting groove 214 is fixedly provided in the middle of the base 201, and several groups of reset spring groups 215 are fixedly provided in the mounting groove 214. The other end of the reset spring group 215 abuts against the bottom of the base column 202. Multiple groups of connecting blocks 212 are fixedly provided at the bottom of the base column 202. A second fixing bolt 213 is provided on the connecting block 212. The base column 202 and the base 201 are fixedly connected by the second fixing bolt 213.

[0025] Several groups of return spring groups 215 are arranged in the installation groove 214 opened in the middle of the base 201. One end of these return spring groups 215 is fixedly connected to the bottom of the installation groove 214, and the other end is abutted against the bottom of the base column 202. The design of the return spring group 215 is to produce a certain elastic deformation when subjected to external force, thereby absorbing and buffering the impact force and maintaining the stability of the support assembly 2. Multiple groups of connecting blocks 212 are fixedly provided at the bottom of the base column 202. These connecting blocks 212 are provided with second fixing bolts 213. By tightening the second fixing bolts 213, the base column 202 and the base 201 can be firmly connected together to ensure that the overall structure of the support assembly 2 is stable and reliable.

[0026] As an optional embodiment, the diameter of the base column 202 is slightly smaller than the opening diameter of the mounting groove 214. When the base column 202 is fixedly connected to the base 201, the return spring assembly 215 is in a compressed state.

[0027] The diameter of the base column 202 is slightly smaller than the opening diameter of the mounting groove 214. This design enables the base column 202 to be smoothly inserted into the mounting groove 214 and maintain a certain gap between the base column 202 and the mounting groove 214. The existence of this gap can accommodate the reset spring group 215 and ensure that the base column 202 will not be subject to excessive resistance during the installation process. When the support component 2 is subjected to external force, the elastic deformation of the reset spring group 215 can maintain the stability of the device. This design can effectively reduce the vibration and shaking of the support component 2 and improve the stability of the entire support platform.

[0028] As an optional embodiment, two groups of symmetrical first fixing bolts 4 are fixed at the four corners of the supporting main board 1, and two groups of symmetrical threaded holes 211 are fixed at the upper end of the connecting plate 210. The connecting plate 210 and the supporting main board 1 are fixedly connected by the first fixing bolts 4.

[0029] Through the cooperation of the first fixing bolt 4 and the threaded hole 211, a stable and adjustable connection structure is formed between the support main board 1 and the connecting plate 210, which improves the structural stability and installation convenience of the support platform and provides reliable support for subway bridge construction.

[0030] Preferably, a plurality of evenly distributed grids 3 are fixedly provided on the surface of the supporting main board 1 .

[0031] Through the dispersing effect of the grid 3 structure, the supporting main board 1 can bear greater weight and load, which not only improves the bearing capacity, stability and economy of the supporting platform, but also optimizes material usage and heat dissipation and drainage performance, providing better support and protection for subway bridge construction.

[0032] When the present invention is in use, the staff can fix the base column 202 and the connecting plate 210 together through the second fixing bolt 213, and then adjust the height of the telescopic column 209 through the hydraulic shaft 208 according to the actual situation, so that the connecting plate 210 is against the support main board 1 to reach a balanced state, and then adjust the stretching angle of the support arm 205, and drive the conical fixing part 207 into the ground to improve the stability of the device. The several groups of reset spring groups 215 arranged in the installation groove 214 opened in the middle of the base 201 can produce a certain elastic deformation when the device is subjected to external force, thereby absorbing and buffering the impact force and maintaining the stability of the support assembly 2.

Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
