[0028] [First Embodiment]

[0029] Refer to Figures 1 to 4 The first embodiment provided by the present utility model is shown as follows. This embodiment provides a steel frame bridge support structure. As Figure 1 shown, it includes a support column 1. A base plate 2 is fixedly connected to the bottom of the support column 1. Connection devices 3 are arranged on both sides of the support column 1. By setting the connection devices, compared with the chain and rope connection methods in the prior art, a higher-strength connection relationship can be formed between several support columns that play a supporting role on both sides of the steel frame bridge, thereby ensuring the stable position of the support columns and making it not easy to shake during use, so that the steel frame bridge is more stable and the use effect and practicality of the support structure are improved.

[0030] As Figures 2 - 3 shown, the connection device 3 in this embodiment includes a rotating member 31. The rotating member 31 is fixedly connected to one side of the support column 1. A connecting plate 32 is rotatably connected to the outer periphery of the rotating shaft of the rotating member 31. A jack 36 is opened inside the connecting plate 32. An insertion plate 35 is inserted into the inside of the jack 36 and is in plug-in fit with it to realize the plug-in fixation of the connecting plate 32. A connecting block 33 fixed to the steel frame bridge is accommodated inside the insertion plate 35. A screw 34 is threadedly connected inside the insertion plate 35. One end of the screw 34 penetrates through the insertion plate 35 and extends into the inside of the connecting block 33 and is threadedly connected with it. The fixed connection of the insertion plate 35 at the bottom of the connecting block 33 is realized through the threaded connection method of the screw 34; preferably, as Figures 1 - 3 shown, the insertion plate 35 in this embodiment is set to be multi-clawed (quadruple-clawed in this embodiment) to realize the comprehensive and uniform coverage of the connecting block 33; and the cross-section of the connecting block 33 is set to be T-shaped to facilitate plugging into the inside of the insertion plate 35.

[0031] As Figures 2 - 3As shown in the figure, the plugging method in this embodiment is as follows: A limiting rod 38 is fixedly connected to the top of the plug board 35. Limiting grooves 37 are respectively formed on the outer sides of the connecting blocks 33. The limiting rod 38 is located inside the limiting groove 37 and is slidably connected thereto. Through the sliding arrangement of the limiting rod 38 and the limiting groove 37, when the screw rod 34 rotates, the position of the plug board can be ensured to be stable and not prone to deflection, and the plug board 35 can be quickly inserted into the limiting groove 37 formed on the outer side of the connecting block 33, ensuring the normal use of the connecting device.

[0032] As Figure 2 shown in the figure, clamping blocks 310 are respectively arranged on both sides of the connecting block 33. A clamping groove 39 is formed at the top of the side of the connecting plate 32 away from the support column 1. The clamping block 310 is inserted into the clamping groove 39 and is in clamping fit therewith. Through the clamping fit of the clamping block 310 and the clamping groove 39, the connecting plate 32 can be stably contacted and pressed against the surface of the connecting block 33, ensuring the stability of the position and improving the connection stability between adjacent support columns.

[0033] As Figure 3 shown in the figure, a nut 311 is threadedly connected to the outer circumference of the screw rod 34. The nut 311 abuts against the bottom of the plug board 35. Through the setting of the nut 311, when the screw rod drives the plug board to fix the connecting plate, the screw rod is not prone to rotational loosening due to the nut contacting and pressing against the surface of the plug board. At the same time, a limiting ring 312 is fixedly connected to the arc surface of the screw rod 34. The inner wall of the limiting ring 312 is threadedly connected to the screw rod 34. The axial plugging position of the plug board 35 is limited by the limiting ring 312 to meet the requirements of different axial sliding positions of the plug board 35.

[0034] As Figure 4 shown in the figure, a reinforcing device 4 is arranged on the outer circumference of the support column 1. By setting the reinforcing device, the support column can be reinforced, thereby further improving the support stability of the bridge main body.

[0035] In this embodiment, the reinforcement device 4 includes a fixing ring 43 slidably connected to the outer periphery of the support column 1. A reinforcement groove 42 is formed in the inner wall of the fixing ring 43. The top of the reinforcement plate 41 is inserted into the inside of the reinforcement groove 42, and the bottom of the reinforcement plate 41 is clamped with the base plate 2. A bolt 44 passes through the fixing ring 43 and is threadedly connected to the support column 1; this makes the position of the support column more stable and not prone to swaying, ensuring the stable limiting of the steel truss bridge structure by the support column, and improving the practicality and use effect of the support column. Positioning plates 45 are respectively fixedly connected to the outer periphery of the support column 1, and the positioning plates 45 are inserted and matched with the inner wall of the reinforcement plate 41. Through the arrangement of the positioning plates, the connection strength between the reinforcement plate and the support column is further improved, making the position of the reinforcement plate more stable and ensuring the stable support of the support column; positioning blocks 47 are respectively fixed at the four corners of the support column 1, and positioning grooves 46 are respectively formed at the four corners of the inner wall of the fixing ring 43. The positioning blocks 47 are located inside the positioning grooves 46 and are inserted and matched with them. Through the insertion of the positioning blocks and the positioning grooves, the assembly position of the fixing ring is more stable and does not shake or shift, and thus better forms a support effect on the support column.

[0036] The specific working process of this embodiment is as follows:

[0037] When the support column 1 is supporting and protecting the steel truss bridge, rotate the connecting plates 32 on both sides of the support column 1, so that the connecting plates 32 rotate through the rotating shafts of the rotating members 31 fixed to the support column 1 until the connecting plates 32 contact and press against the surface of the connecting block 33 on one side of the bottom of the steel truss bridge. Then rotate the screw 34 on the connecting block 33. Through the sliding limit of the insertion plate 35 by the limit rod 38 and the limit groove 37, when the screw 34 rotates, it is not easy to make the insertion plate 35 move until the insertion plate 35 is inserted into the insertion holes 36 on the connecting plates 32 on both sides of the connecting block 33. Then rotate the nut 311 on the screw 34 so that the nut 311 contacts and presses against the surface of the insertion plate 35. By setting the connecting device, compared with the chain and rope connection methods in the prior art, a higher-strength connection relationship can be formed between several support columns that play a supporting role on both sides of the steel truss bridge, thereby ensuring the stable position of the support columns and not being prone to shaking during use, making the steel truss bridge more stable, and improving the use effect and practicality of the support structure.

[0038] When the support column 1 forms stable support for the steel truss bridge, first slide down the fixing ring 43 on the support column 1 until the reinforcing groove 42 on the inner wall of the fixing ring 43 is inserted into one side of the reinforcing plate 41 clamped to the surface of the base plate 2. Then, penetrate bolts 44 through the inner walls around the fixing ring 43 until the bolts 44 extend into the support column 1 and are threadedly connected thereto. By providing the reinforcing device, the outer periphery of the top of the support column can be restricted by the fixing ring, the bottom is fixed by plugging through the base plate, and the middle part can achieve positioning and reinforcement functions through the reinforcing plate and the positioning plate, thereby further reinforcing the support column and further improving the support stability of the bridge main body.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
