DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] An embodiment provided by the present invention: a spliced ​​construction temporary floating bridge, such as Figure 1 and Figure 2 As shown, it includes a pontoon layer 1, a bridge end assembly 2, a bridge end intersection connector 3, a floating bridge surface assembly 4, an underwater positioning member, an onshore positioning member and an isolation guardrail 6.

[0040] like Figure 3 and Figure 4 As shown, the pontoon layer 1 is composed of a plurality of pontoons 11 distributed in a matrix, and adjacent pontoons 11 are connected by plug-in components, which include convex blocks 112 and concave parts 111. The pontoons 11 are hexagonal prisms with a square cross section, and plug-in components are arranged around the pontoons 11. The pontoons 11 are arranged on two adjacent sides, and concave parts 111 are arranged on the other two sides. The concave parts 111 of the pontoons 11 are plugged in one-to-one with the convex blocks 112 of the adjacent installed pontoons 11. The temporary floating bridge can adjust the length and width of the pontoon layer 1 according to the actual required size of the river channel through the structural mode of splicing and combining the pontoons 11 to adapt to different usage scenarios and needs.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, there are multiple groups of bridge end components 2, which are arranged along the edges of the pontoon layer 1. The bridge end components 2 in different directions around the pontoon layer 1 are connected by the bridge end intersection connector 3, and the bridge end components 2 are connected to the pontoon layer 1 through the plug-in component. Figure 7 As shown, the bridge end assembly 2 includes a pontoon connector 21 and a bridge end body 22. The pontoon connector 21 is arranged on one side of the bridge end body 22 close to the pontoon layer 1, and is a hexagonal prism with a rectangular cross section. The pontoon connector 21 is connected to the adjacent pontoon 11 through a plug-in assembly. The pontoon connector 21 has two structures, one with a protrusion 112 and one with a recess 111. The pontoon connector 21 with the protrusion 112 is plugged into the position corresponding to the recess 111 of the adjacent pontoon 11, and the pontoon connector 21 with the protrusion 112 is plugged into the position corresponding to the protrusion 112 of the adjacent pontoon 11. The combination of the connector 3 at the intersection of the bridge end assembly 2 and the bridge end around the pontoon layer 1 ensures the integrity of the main part of the temporary floating bridge, while increasing the stability of the floating bridge.

[0042] like Figure 2 As shown, the upper surface of the pontoon layer 1 is provided with a floating bridge surface layer assembly 4. Figure 8 As shown, the floating bridge surface layer components 4 are arranged in a matrix. Fig. 9 , Fig.10 and Fig.11 As shown, the floating bridge surface layer assembly 4 is divided into an intermediate floating bridge surface layer member 4a, a side floating bridge surface layer member 4b and a corner floating bridge surface layer member 4c. Positioning grooves 115 are provided on the surfaces of the pontoons 11, the pontoon connectors 21 and the connectors 3 at the intersection of the bridge ends. The intermediate floating bridge surface layer member 4a is fixed on the combination of four pontoons 11 through the positioning grooves 115. The side floating bridge surface layer member 4b is fixed on the combination of two pontoons 11 and two pontoon connectors 21 through the positioning grooves 115. The corner floating bridge surface layer member 4c is fixed on the combination of the pontoons 11, the connectors 3 at the intersection of the bridge ends and the two pontoon connectors 21 through the positioning grooves 115. The floating bridge surface layer assembly 4 thus assembled can completely cover the entirety of the pontoon layer 1, the bridge end assembly 2 and the connectors 3 at the intersection of the bridge ends. On the one hand, the floating bridge surface layer assembly 4 covering the pontoon layer 1 ensures the flatness of the floating bridge road surface; on the other hand, the connection between the floating bridge surface layer assembly 4 and the pontoon layer 1, the connection between the bridge end assembly 2 and the bridge end, combined with the connection method of the plug-in assembly between the pontoon layer 1, the bridge end assembly 2 and the bridge end, makes the temporary floating bridge fixed as a stable whole, and the combination method is simple and easy to operate, which is convenient for its installation and disassembly as a temporary floating bridge; finally, when the floating bridge surface layer assembly 4 is subjected to the pressure of vehicles and pedestrians, it ensures that the pontoon layer 1 can be evenly stressed and not easily deformed, thereby improving the stability of the floating bridge; on the other hand, the floating bridge surface layer assembly 4 acts as an isolation layer to protect the pontoon 11 from damage, thereby avoiding the buoyancy effect of the pontoon 11 being affected by water ingress.

[0043] like Fig.12 As shown, the floating bridge surface layer components 4 include a frame 41 and a bridge deck member 42. The bridge deck member 42 is embedded in the frame 41. The edge shape of the bridge deck member 42 is consistent with the shape of the frame 41. The bottom of the bridge deck member 42 falls on the surface of the pontoon 11, the pontoon connector 21 or the connector 3 at the intersection of the bridge end.

[0044] like Figure 4 , Figure 7 and Fig.12 As shown, the four bottom corners of the frame 41 are all provided with downward extending positioning pieces 412, which are L-shaped and inserted into the positioning groove 115. The positioning groove 115 of the pontoon 11 is a cross-shaped groove located at the center of the pontoon 11, and the downward extending positioning pieces 412 of four adjacent groups of frames 41 installed on the same pontoon 11 are inserted into the cross-shaped positioning groove 115 of the pontoon 11 together; the positioning groove 115 of the pontoon connector 21 is a T-shaped groove located in the center of the edge of the pontoon connector 21, and the downward extending positioning pieces 412 of two adjacent groups of frames 41 installed on the same group of pontoon connectors 21 are inserted into the T-shaped positioning groove 115 of the pontoon connector 21 together; the positioning groove 115 of the connector 3 at the intersection of the bridge ends fixes the downward extending positioning pieces 412 of the four corners of the floating bridge surface layer assembly 4. The positioning grooves 115 ensure that the floating bridge surface layer components 4 are all limited in fixed positions and are not easily offset relative to the pontoon layer 1, thereby maintaining the flatness and stability of the surface of the floating bridge surface layer components 4.

[0045] The middle floating bridge surface layer member 4a is a square with the same side length as the pontoon 11, the side floating bridge surface layer member 4b is a rectangle with the same long side as the pontoon 11 and the short side being the length of the pontoon 11 plus the short side of the pontoon connector 21, and the corner floating bridge surface layer member 4c is a square with the length of the pontoon 11 plus the short side of the pontoon connector 21. The positioning groove 115 of the pontoon 11 is located at its center, and the positioning groove 115 of the bridge end assembly 2 is located in the middle of its long side. Therefore, if pedestrians and vehicles cause the floating bridge surface layer assembly 4 to be stressed, the pressure points of its four corners below just fall on the center of the pontoon 11 and the middle of the long side of the bridge end assembly 2, which is convenient for dispersing pressure to the surroundings. The center of the pontoon 11 and the middle of the long side of the bridge end assembly 2 are more able to withstand pressure than their respective parts, avoiding damage and deformation of the connection between the pontoon 11 and the bridge end assembly 2 when stressed, and maintaining the stability and safety of the temporary floating bridge.

[0046] like Fig.13As shown, the bridge end assembly 2 also includes a positioning member installation member 23, and the positioning member installation member 23 is arranged on the side of the bridge end body 22 away from the pontoon layer 1. The underwater positioning member is installed on the positioning member installation member 23 located on the bridge end assembly 2 on the shore, and the onshore positioning member is installed on the positioning member installation member 23 located on the bridge end assembly 2 on the shore. The temporary floating bridge is positioned by installing the onshore positioning members or the underwater positioning members around it, which can protect the temporary floating bridge from turning over and prevent the temporary floating bridge from drifting with the water flow or wind and waves.

[0047] like Fig.14 As shown, the positioning member installation member 23 includes an external connection frame 231 and a limiting plate 232. The limiting plate 232 is connected to the bridge end body 22 through the external connection frame 231. The limiting plate 232 is hingedly connected to the external connection frame 231. The external connection frame 231 is provided with two groups, and the external connection frame 231 is symmetrically arranged about the limiting plate 232. The underwater positioning member and the onshore positioning member are installed on the limiting plate 232 of the positioning member installation member 23 from top to bottom. The positioning member installation member 23, which does not need to be connected to the onshore positioning member or the underwater positioning member, can be rotatably stored on the side of the bridge end body 22, reducing the volume of the bridge end assembly 2, and facilitating the storage and carrying of the temporary floating bridge during transportation or storage after use.

[0048] The positioning member installation member 23 also includes a spring damper 233, and the two ends of the spring damper 233 are respectively fixedly connected to the external connection frame 231 and the bridge end body 22. Under the action of the spring damper 233, a horizontal range of movement is provided between the combination of the pontoon layer 1 and the bridge end assembly 2 and the position of the onshore positioning member or the underwater positioning member. When the temporary floating bridge is affected by strong winds or turbulent river conditions, the spring damper 233 in different circumferential directions of the combination of the pontoon layer 1 and the bridge end assembly 2 will be squeezed or stretched. Under the buffering force of the spring damper 233, the drift amplitude of the combination of the pontoon layer 1 and the bridge end assembly 2 on the water surface can be reduced, thereby improving the stability and safety of the temporary floating bridge. At the same time, the temporary floating bridge can move horizontally within the range of movement, reducing the impact of water flow or wind direction on the temporary floating bridge, and extending the service life of the temporary floating bridge.

[0049] like Fig.15 and Fig.16As shown, the onshore positioning member includes a ground positioning plate 52 and a plug-in 53, the plug-in 53 is arranged at the bottom of the ground positioning plate 52, the plug-in 53 can pass through the through hole of the limiting plate 232 and the ground positioning plate 52 cannot pass through the through hole of the limiting plate 232; the underwater positioning member includes an underwater support rod 51, a plug-in 53 and a height adjustment member 54, the plug-in 53 is arranged at the bottom of the underwater support rod 51, the underwater support rod 51 is vertically slidably connected in the through hole of the limiting plate 232 through the height adjustment member 54, the height adjustment member 54 and the bottom of the ground positioning plate 52 are both provided with a first clamping member 56, the height adjustment member 54 and the ground positioning plate 52 are both clamped and connected with the first positioning hole 2321 on the limiting plate 232 through the first clamping member 56. When the underwater positioning member and the onshore positioning member are installed on the limiting plate 232, the first clamp 56 at the bottom of the ground positioning plate 52 is fixed in the first positioning hole 2321 on the limiting plate 232 on the shore. At this time, the plug-in 53 below the ground positioning plate 52 is fixed to the ground on the shore; the first clamp 56 at the bottom of the height adjustment member 54 sleeved on the side of the underwater support rod 51 is fixed in the first positioning hole 2321 on the limiting plate 232 at the water surface. At this time, the height of the underwater support rod 51 can be adjusted so that the plug-in 53 at its bottom is fixed to the bottom of the water.

[0050] like Fig.17 and Fig.18As shown, the height adjustment member 54 includes a base 541, a stand 542, a roller 543, a first gear 544 and a top seat 545. The first clamp 56 is located at the bottom of the base 541. The base 541 is connected to the limiting plate 232. The underwater support rod 51 passes through the through groove of the base 541. Two groups of stand 542 are arranged above the base 541. The two groups of stand 542 are both equipped with rollers 543 on one side close to the underwater support rod 51. The two sides of the underwater support rod 51 close to the rollers 543 are arranged with convex teeth 51 1, wherein a roller 543 of a group of vertical members 542 is coaxially connected to a first gear 544, a top seat 545 is arranged above the vertical member 542, an adjustment auxiliary member 55 is installed on one side of the top seat 545, and the adjustment auxiliary member 55 comprises a motor 551, a positioning plug rod 552 and a second gear 553, the body of the motor 551 is plugged into the socket 5451 on the top seat 545 through the positioning plug rod 552, the output end of the motor 551 is connected to the second gear 553, and the second gear 553 is meshed with the first gear 544. When the underwater support rod 51 is inserted into the bottom of the water, the adjustment auxiliary component 55 is used to help complete the installation of the underwater positioning component on each limiting plate 232, and the underwater support rod 51 is located between the two groups of rollers 543 and extended into the water, and the positioning rod 552 of the adjustment auxiliary component 55 is inserted into the insertion hole 5451, and the motor 551 of the adjustment auxiliary component 55 drives the second gear 553 to rotate, and the second gear 553 is matched with the first gear 544, and the first gear 544 rotates accordingly, and the first gear 544 drives the rotation of the roller 543 on the vertical component 542, and the roller 543 rotates and acts on the position of the convex tooth 511 of the underwater support rod 51, and the roller 543 on the other side rotates accordingly, and during the rotation of the two groups of rollers 543, the underwater support rod 51 is stably driven downward and firmly inserted into the bottom of the water, thereby completing the positioning of the side of the floating bridge contacting the water body. The installation method of the adjustment auxiliary part 55 improves the efficiency of the installation of each group of underwater positioning parts, can save manpower, and is more firmly fixed than manual operation of the underwater support rod 51. In the face of strong winds or turbulent rivers and when the floating bridge bears a large load, the roller 543 on the limit plate 232 rolls on the side of the underwater support rod 51, which can ensure that the temporary floating bridge as a whole is adjusted up and down according to different situations, reduce the deformation and damage of the temporary floating bridge caused by the impact or pressure of water waves, and extend the service life of the temporary floating bridge; at the same time, during the up and down adjustment process of the temporary floating bridge, the roller 543 slides on the underwater support rod 51, and the convex teeth 511 play a buffering role, which can reduce the speed of change when the temporary floating bridge is raised and lowered, so that the temporary floating bridge can be raised and lowered smoothly, thereby ensuring the safety of pedestrians and vehicles on the floating bridge road.

[0051] like Fig.19 As shown, an isolation guardrail 6 is arranged between two adjacent groups of underwater support rods 51.
