[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Through the arrangement of the onshore positioning piece or the underwater positioning piece, the present invention realizes the positioning of the temporary floating bridge by installing the onshore positioning piece or the underwater positioning piece around the temporary floating bridge, which can protect the temporary floating bridge from tipping over and prevent the temporary floating bridge from drifting with the water flow or wind and waves.

[0023] 3. By providing the roller and the underwater strut in the present invention, in the face of strong wind weather, rapid river flow or heavy load on the floating bridge, the roller on the limit plate member rolls on the side of the underwater strut, which can ensure that the whole temporary floating bridge adjusts up and down according to different situations, reduce the deformation and damage of the temporary floating bridge caused by water wave impact or pressure, extend the service life of the temporary floating bridge. At the same time, during the up and down adjustment of the temporary floating bridge, the roller slides on the underwater strut, and the convex teeth play a buffering role, which can reduce the change speed when the temporary floating bridge rises and falls, so that the temporary floating bridge rises and falls smoothly, thus ensuring the safety of pedestrians and vehicles on the floating bridge road surface.

[0024] 4. In the present invention, the temporary floating bridge, including the floating box, the bridge end assembly, the floating bridge surface layer assembly, the underwater positioning member, the onshore positioning member and the isolation guardrail, all adopt a spliced and modular installation structure.

DETAILED DESCRIPTION

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 1 ,Figure 5 and Figure 6 As shown in Figure 6 , multiple sets of bridge end components 2 are provided, which are arranged along the four peripheries of the floating box layer 1. The bridge end components 2 in different directions on the periphery of the floating box layer 1 are connected by the bridge end intersection connectors 3. The bridge end components 2 are connected to the floating box layer 1 through the plug-in components. As Figure 7 shown in Figure 7 , the bridge end component 2 includes a floating box connector 21 and a bridge end body 22. The floating box connector 21 is arranged on the side of the bridge end body 22 close to the floating box layer 1, and is a hexagonal prism with a rectangular cross-section. The floating box connector 21 is connected to the adjacent floating box 11 through the plug-in component. The floating box connector 21 has two structures, one with a convex block 112 and the other with a concave part 111. The floating box connector 21 with the convex block 112 is inserted into the corresponding position of the concave part 111 of the adjacent floating box 11, and the floating box connector 21 with the convex block 112 is inserted into the corresponding position of the convex block 112 of the adjacent floating box 11. The combination of the bridge end component 2 and the bridge end intersection connector 3 around the floating box layer 1 ensures the integrity of the main part of the temporary floating bridge, and at the same time increases the stability of the floating bridge.

[0050] As Figure 2 shown in Figure 2 , a floating bridge surface layer component 4 is arranged on the upper surface of the floating box layer 1. As Figure 8 shown in Figure 8 , the floating bridge surface layer components 4 are distributed in a matrix. As Figure 9 , Figure 10 and Figure 11 shown in Figure 9 , Figure 10 and Figure 11 , the floating bridge surface layer component 4 is divided into a middle floating bridge surface layer part 4a, a side floating bridge surface layer part 4b and a corner floating bridge surface layer part 4c. Positioning grooves 115 are provided on the surfaces of the floating box 11, the floating box connector 21 and the bridge end intersection connector 3. The middle floating bridge surface layer part 4a is fixed above the combination of four floating boxes 11 through the positioning grooves 115, the side floating bridge surface layer part 4b is fixed above the combination of two floating boxes 11 and two floating box connectors 21 through the positioning grooves 115, and the corner floating bridge surface layer part 4c is fixed above the combination of the floating box 11, the bridge end intersection connector 3 and two floating box connectors 21 through the positioning grooves 115. The combined floating bridge surface layer component 4 can completely cover the whole of the floating box layer 1, the bridge end component 2 and the bridge end intersection connector 3. The floating bridge surface layer component 4 covering the floating box layer 1 ensures the flatness of the floating bridge road surface on the one hand; on the other hand, the connection of the floating bridge surface layer component 4 with the floating box layer 1, the bridge end component 2 and the bridge end intersection connector 3, combined with the connection method of the plug-in components between the floating box layer 1, the bridge end component 2 and the bridge end intersection connector 3, makes the temporary floating bridge fixed as a stable whole. The combination method is simple and easy to operate, facilitating the installation and disassembly of the temporary floating bridge; finally, when the floating bridge surface layer component 4 is subjected to the pressure of vehicles and pedestrians, it ensures that the floating box layer 1 can be evenly stressed and is not easily deformed, thereby improving the stability of the floating bridge; on the other hand, the floating bridge surface layer component 4 serves as an isolation layer to protect the floating box 11 from damage and avoid affecting the buoyancy effect of the floating box 11 after water ingress.

[0051] As Figure 12 shown, the pontoon bridge surface layer assembly 4 all includes a frame 41 and bridge deck members 42. The bridge deck members 42 are embedded inside the frame 41. The edge shape of the bridge deck members 42 conforms to the shape of the frame 41. The bottom of the bridge deck members 42 rests on the surface of the pontoons 11, the pontoon connectors 21 or the connectors 3 at the intersection of the bridge ends.

[0052] As Figure 4 、 Figure 7 and Figure 12 shown, downward extension positioning members 412 are provided at the four bottom corners of the frame 41. The downward extension positioning members 412 are L-shaped and are inserted into the positioning grooves 115. The positioning grooves 115 of the pontoons 11 are cross-shaped grooves located at the central part of the pontoons 11. The downward extension positioning members 412 of four adjacent groups of frames 41 installed on the same pontoon 11 are jointly inserted into the cross-shaped positioning grooves 115 of the pontoon 11. The positioning grooves 115 of the pontoon connectors 21 are T-shaped grooves located in the middle of the edges of the pontoon connectors 21. The downward extension positioning members 412 of two adjacent groups of frames 41 installed on the same group of pontoon connectors 21 are jointly inserted into the T-shaped positioning grooves 115 of the pontoon connectors 21. The positioning grooves 115 of the connectors 3 at the intersection of the bridge ends fix the downward extension positioning members 412 at the four corners of the pontoon bridge surface layer assembly 4. The setting of the positioning grooves 115 ensures that the pontoon bridge surface layer assemblies 4 are all limited in fixed positions, not easily offset relative to the pontoon layer 1, and maintain the flatness and stability of the surface of the pontoon bridge surface layer assemblies 4.

[0053] The middle pontoon bridge surface member 4a is a square with a side length the same as that of the pontoon 11. The side pontoon bridge surface members 4b are rectangles with a long side the same as the side length of the pontoon 11 and a short side being the sum of the side length of the pontoon 11 and the short side of the pontoon connector 21. The corner pontoon bridge surface members 4c are squares with a side length being the sum of the side length of the pontoon 11 and the short side of the pontoon connector 21. The positioning grooves 115 of the pontoons 11 are located at their centers, and the positioning grooves 115 of the bridge end assemblies 2 are located in the middle of their long sides. Therefore, when pedestrians and vehicles apply force to the pontoon bridge surface layer assembly 4, the pressure points on the four corners below exactly fall on the centers of the pontoons 11 and the middle of the long sides of the bridge end assemblies 2, facilitating the dispersion of pressure to the surrounding areas. The centers of the pontoons 11 and the middle of the long sides of the bridge end assemblies 2 can withstand pressure better than their respective parts, avoiding damage and deformation to the connection parts between the pontoons 11 and the bridge end assemblies 2 when stressed, and maintaining the stability and safety of the temporary pontoon bridge.

[0054] As Figure 13As shown, the bridge end assembly 2 further includes a positioning member mounting member 23, and the positioning member mounting member 23 is disposed on the side of the bridge end body 22 away from the floating box layer 1. The underwater positioning member is mounted on the positioning member mounting member 23 of the bridge end assembly 2 on the shore, and the shore positioning member is mounted on the positioning member mounting member 23 of the bridge end assembly 2 on the shore. By installing the shore positioning member or the underwater positioning member around the temporary floating bridge, the positioning of the temporary floating bridge is achieved, which can protect the temporary floating bridge from tipping over and prevent the temporary floating bridge from drifting with the water flow or wind and waves.

[0055] As Figure 14 shown, the positioning member mounting member 23 includes an outer connecting frame 231 and a limiting plate member 232. The limiting plate member 232 is connected to the bridge end body 22 through the outer connecting frame 231. The limiting plate member 232 is hingedly connected to the outer connecting frame 231. There are two groups of outer connecting frames 231, and the outer connecting frames 231 are symmetrically arranged about the limiting plate member 232 in the left and right directions. The underwater positioning member and the shore positioning member are installed through the limiting plate member 232 of the positioning member mounting member 23 from top to bottom. The positioning member mounting member 23 that does not need to connect the shore positioning member or the underwater positioning member can be rotatably retracted to 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.

[0056] The positioning member mounting member 23 further includes a spring damper 233. The two ends of the spring damper 233 are respectively fixedly connected to the outer connecting frame 231 and the bridge end body 22. Under the action of the spring damper 233, an activity range in the horizontal direction is provided between the combination of the floating box layer 1 and the bridge end assembly 2 and the position of the shore positioning member or the underwater positioning member. When the temporary floating bridge is affected by strong wind weather or rapid river conditions, it will squeeze or stretch the spring dampers 233 in different circumferential directions of the combination of the floating box layer 1 and the bridge end assembly 2. Under the buffering force of the spring dampers 233, the drifting amplitude of the combination of the floating box layer 1 and the bridge end assembly 2 on the water surface can be reduced, improving the stability and safety of the temporary floating bridge. At the same time, the temporary floating bridge can translate within the activity range, reducing the impact force of the water flow or wind direction on the temporary floating bridge and extending the service life of the temporary floating bridge.

[0057] As Figure 15 and Figure 16As shown, the onshore positioning member includes a ground positioning plate 52 and a plug-in member 53. The plug-in member 53 is arranged at the bottom of the ground positioning plate 52. The plug-in member 53 can pass through the through hole of the limit plate member 232 while the ground positioning plate 52 cannot pass through the through hole of the limit plate member 232. The underwater positioning member includes an underwater support rod 51, a plug-in member 53 and a height adjusting member 54. The plug-in member 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 limit plate member 232 through the height adjusting member 54. The bottom of both the height adjusting member 54 and the ground positioning plate 52 are provided with a first clamping member 56. The height adjusting member 54 and the ground positioning plate 52 are both clamped and connected to the first positioning hole 2321 on the limit plate member 232 through the first clamping member 56. When the underwater positioning member and the onshore positioning member are installed on the limit plate member 232, the first clamping member 56 at the bottom of the ground positioning plate 52 is fixed in the first positioning hole 2321 on the limit plate member 232 on the shore. At this time, the plug-in member 53 under the ground positioning plate 52 is fixed on the ground on the shore. The first clamping member 56 at the bottom of the height adjusting member 54 sleeved on the peripheral side of the underwater support rod 51 is fixed in the first positioning hole 2321 on the limit plate member 232 at the water surface. At this time, the height of the underwater support rod 51 can be adjusted so that the plug-in member 53 at its bottom is fixed on the underwater bottom.

[0058] As Figure 17 and Figure 18As shown, the height adjuster 54 includes a base 541, a vertical member 542, a roller 543, a first gear 544, and a top seat 545. The first clamping member 56 is located at the bottom of the base 541. The base 541 is connected to the limit plate member 232. The underwater strut 51 passes through the through groove of the base 541. Two groups of vertical members 542 are arranged above the base 541. Rollers 543 are installed on one side of each of the two groups of vertical members 542 close to the underwater strut 51. Convex teeth 511 are arranged on two side surfaces of the underwater strut 51 close to the rollers 543. The roller 543 of one group of vertical members 542 is coaxially connected to the 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. The adjustment auxiliary member 55 includes a motor 551, a positioning plug 552, and a second gear 553. The body of the motor 551 is inserted and connected to the jack 5451 on the top seat 545 through the positioning plug 552. The output end of the motor 551 is connected to the second gear 553. The second gear 553 is meshed and connected with the first gear 544. When the underwater strut 51 is inserted into the bottom of the water, the adjustment auxiliary member 55 can help the underwater positioning members on each limit plate member 232 to complete the installation. Place the underwater strut 51 between the two rollers 543 and extend it into the water. Insert the positioning plug 552 of the adjustment auxiliary member 55 into the jack 5451. The motor 551 of the adjustment auxiliary member 55 drives the second gear 553 to rotate. Match the second gear 553 with the first gear 544. The first gear 544 rotates accordingly. The first gear 544 drives the rotation of the roller 543 on the vertical member 542 where it is located. The roller 543 rotates and acts on the position of the convex teeth 511 of the underwater strut 51. The roller 543 on the other side rotates accordingly. During the rotation of the two rollers 543, the underwater strut 51 is stably driven downward and firmly inserted into the bottom of the water, thus completing the positioning of the side of the floating bridge in contact with the water body. The installation method of the adjustment auxiliary member 55 improves the installation efficiency of each underwater positioning member, can save manual operation, and is more firmly fixed than manually operating the underwater strut 51. In the face of strong wind weather, fast-flowing rivers, or heavy loads on the floating bridge, the rollers 543 on the limit plate member 232 roll on the side of the underwater strut 51, which can ensure that the overall temporary floating bridge adjusts up and down according to different situations, reduce the deformation and damage of the temporary floating bridge caused by water wave impact or pressure, and extend the service life of the temporary floating bridge; at the same time, during the up and down adjustment of the temporary floating bridge, the rollers 543 slide on the underwater strut 51, and the convex teeth 511 play a buffering role, which can reduce the change speed when the temporary floating bridge rises and falls, so that the temporary floating bridge rises and falls smoothly, thus ensuring the safety of pedestrians and vehicles on the floating bridge road surface.

[0059] As Figure 19 shown, an isolation guardrail 6 is arranged between two adjacent groups of underwater struts 51. The isolation guardrail 6 includes a top ring 61, a whole ring 62, a ring connecting member 63, a rope blocking connecting member 64, and a rope blocking member 65. The top ring 61 is installed between the two convex teeth 511 of the two groups of underwater struts 51. AsFigure 20 As shown in the figure, the top ring 61 is composed of two sets of fixed semi-rings 611. The fixed semi-ring 611 is U-shaped. One end of the fixed semi-ring 611 is provided with a second clamping member 6111, and the other end is provided with a second positioning hole 6112. The second positioning holes 6112 of the two sets of fixed semi-rings 611 are correspondingly clamped and connected with the second clamping members 6111. The integral ring 62 is sleeved on the underwater strut 51. The lower part of the top ring 61 is connected with multiple sets of ring connectors 63 through a rope blocking connector 64. The inner diameter of the integral ring 62 is larger than the outer diameter of the underwater strut 51 at the position of the convex teeth 511, and the inner diameter of the top ring 61 is smaller than the outer diameter of the underwater strut 51 at the position of the convex teeth 511. During installation, first sleeve the integral ring 62 on the underwater strut 51, and then install the top ring 61 at the top. The second clamping member 6111 of one set of fixed semi-rings 611 is fixedly connected with the second positioning hole 6112 of the other set of fixed semi-rings 611. The two sets of fixed semi-rings 611 are spliced into the top ring 61, and the combination is installed on the underwater strut 51 and is limited between the two convex teeth 511. The convex teeth 511 limit the height of the top ring 61. Only the topmost top ring 61 needs to be fixed, and the installation and disassembly steps are simple and easy to operate. Rope blocking connectors 64 are arranged on the circumferences of both the top ring 61 and the integral ring 62. One end of the rope blocking 65 is fixed by the rope blocking connector 64. The rope blocking 65 is respectively connected between adjacent two sets of integral rings 62 and between adjacent two sets of top rings 61. The ends of the rope blocking 65 are fixed by the rope blocking connectors 64 between the top rings 61 or the integral rings 62 on adjacent two sets of underwater struts 51. The rope blocking 65 is used for isolation, playing a protective role to prevent accidents from falling into the water. When the temporary use of the temporary floating bridge ends, the component structures of the isolation guardrail 6 are all convenient for disassembly and secondary installation.

[0060] The temporary floating bridge is composed of floating boxes 11, bridge end components 2, floating bridge surface layer components 4, underwater positioning members, shore positioning members and isolation guardrails 6, all of which are spliced and modular installation structures. On the one hand, the temporary floating bridge can be customized and combined in different sizes according to working conditions during splicing, with a wide range of applications; on the other hand, the operation of the temporary floating bridge is simple, and it can be quickly assembled and disassembled on site, saving time and improving construction efficiency. It is also convenient for disassembly when the temporary use ends. Moreover, the components of the spliced floating bridge can be repeatedly spliced and installed in other places, further reducing costs and improving resource utilization efficiency, and improving the practicality of the temporary floating bridge.
