[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that make travel more convenient by crossing mountain streams, poor geology, or meeting other transportation needs. Bridges need to be analyzed before they are designed, and the bridge construction is often simulated by building a bridge model.

It is not easy to align quickly during splicing, which affects the work efficiency of bridge model splicing; bridge models generally support the bridge deck model through load-bearing column models. If they are accidentally touched, they are prone to tipping over, thereby reducing the stability of the bridge model during use; bridge models are generally disassembled for carrying and transportation, but general bridge models are not easy to store, which can easily lead to the loss of parts of the bridge model during use after a long time.

The plug columns 202 and the sockets 203 are plugged and matched with each other. The bridge deck splicing plates 1 are fixed by the splicing component 201. The splicing component 201 is formed by convex strips 2 011, a groove 2012, a block 2013 and a groove 2014. A groove 2012 is provided on one side of the bridge deck splicing plate 1.

[0029] When in use, since the bridge model can be directly placed on the surface of the base 301 when it is spliced, the fastening bolt 3023 can be loosened to keep the fastening bolt 3023 away from the threaded hole 3022, and then the storage box 3021 can be pulled out, and the model to be spliced ​​can be taken out and directly spliced.

After use, the disassembled model can be directly placed inside the threaded hole 3022, and the model can be directly stored under the action of the threaded hole 3022, so as to realize the function of easy storage of the bridge model.

[0030] Furthermore, if Figure 4 As shown, the surface of the load-bearing column 102 is provided with an adsorption and fixing mechanism 4, which is composed of a negative pressure cavity 401 and an adsorption and fixing component 402. A negative pressure cavity 401 is opened at the bottom position of the load-bearing column 102, and an adsorption and fixing component 402 is arranged on the surface of the load-bearing column 102. The interior of the adsorption and fixing component 402 includes a piston 4021, a movable groove 4022, a magnetic sheet 4023 and a magnet 4024. A movable groove 4022 is opened at the top position of the surface of the load-bearing column 102, and the inner wall of the movable groove 4022 is inlaid with a magnetic sheet 4023. A piston 4021 is arranged inside the negative pressure cavity 401, and the piston 4021 and the negative pressure cavity 401 slide together.

[0031] When in use, the load-bearing column 102 is placed on the surface of the base 301, and then the piston 4021 inside the movable groove 4022 is pulled so that the piston 4021 draws out the air in the negative pressure cavity 401, thereby adsorbing and fixing the load-bearing column 102 and the base 301, making the load-bearing column 102 more stable. At this time, the magnet 4024 moves to be in close contact with the magnetic sheet 4023, and the piston 4021 is fixed under the magnetic attraction cooperation of the magnet 4024 and the magnetic sheet 4023, so as to realize the adsorption and fixing function of the bridge model on the load-bearing column 102.

[0032] Working principle: When in use, first take the bridge deck splicing plate 1 to the side of another bridge deck splicing plate 1, and insert the bottom of the convex strip 2011 into the groove 2012, then push the bridge deck splicing plate 1, and make one end of the convex strip 2011 close to the bottom of the groove 2012 under the sliding cooperation of the convex strip 2011 and the groove 2012, and quickly splice the two bridge deck splicing plates 1. At this time, the clamping block 2013 is clamped into the clamping groove 2014, and the clamping block 2013 and the clamping groove 2014 are locked. The two bridge deck splicing plates 1 are quickly fixed under the snap-fitting action, and then the arch frame 101 is placed on the surface of the spliced ​​bridge deck splicing plates 1, so that the plug column 202 is inserted into the socket 203, and the bridge deck splicing plates 1 and the arch frame 101 are spliced ​​and fixed under the plug-in cooperation of the plug column 202 and the socket 203. Similarly, the bridge deck splicing plates 1 and the load-bearing columns 102 are spliced ​​and fixed to realize the rapid splicing function of the bridge model, thereby improving the work efficiency when splicing the bridge model.

[0033] Then, the load-bearing column 102 is placed on the surface of the base 301, and then the piston 4021 inside the movable groove 4022 is pulled so that the piston 4021 draws out the air in the negative pressure cavity 401, thereby adsorbing and fixing the load-bearing column 102 and the base 301 to make the load-bearing column 102 more stable. At this time, the magnet 4024 moves to be in close contact with the magnetic sheet 4023, and the piston 4021 is fixed under the magnetic attraction cooperation of the magnet 4024 and the magnetic sheet 4023 to realize the adsorption and fixing function of the bridge model on the load-bearing column 102, thereby improving the stability of the bridge model during use.

[0034] Since the bridge model can be directly placed on the surface of the base 301 when it is used, when in use, the fastening bolt 3023 can be loosened to keep the fastening bolt 3023 away from the threaded hole 3022, and then the storage box 3021 can be pulled out, and the model to be spliced ​​can be taken out and directly spliced. If the model needs to be moved, the base 301 can be directly moved. After use, the disassembled model can be directly placed inside the threaded hole 3022, and the model can be directly stored under the action of the threaded hole 3022, so as to realize the function of easy storage of the bridge model, thereby avoiding the phenomenon of loss of parts when the bridge model is used, and finally completing the use of the bridge model.
