Description

Technical Field

[0001] The present invention relates to the field of bridges, and particularly to a detachable floating bridge. Background Art

[0002] As is well known, a floating bridge, that is, a bridge floating on the water with floating bodies replacing bridge piers, is one of the very common bridge types nowadays. The current floating bridge is mainly formed by welding profiles to form a general framework of the bridge body, fixing the floating bodies below the framework, and finally laying bridge boards above the framework. However, since the framework is formed by welding, the shape of such a floating bridge is fixed after being formed and cannot be changed. Therefore, it is impossible to adjust its length, width or shape according to different scenarios. Moreover, the formed framework has a large volume, which has the disadvantage of being inconvenient to carry during transportation such as at the exit. This undoubtedly has problems such as high costs, inconvenience in transporting to mountainous areas for installation construction, and low installation construction efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a detachable floating bridge that can be easily assembled and disassembled.

[0004] The detachable floating bridge according to the first aspect embodiment of the present invention includes: a framework, the framework includes a plurality of connecting beams, and some or all of the plurality of connecting beams are detachably connected to each other in pairs through a threaded structure; floating boxes, detachably connected to the lower part of the framework through a threaded structure; and bridge boards, laid on the framework.

[0005] The detachable floating bridge according to the embodiment of the present invention has at least the following beneficial effects: The connecting beams are connected to form a framework through a threaded structure. Therefore, the framework can be simply disassembled or assembled by releasing the threaded connection, thereby changing the length, width and shape of the framework, and further being applicable to different usage scenarios. At the same time, the floating boxes are also connected to the framework through a threaded structure. Therefore, only by releasing the threaded connections at various places can the floating bridge be disassembled, so that the formed floating bridge can be simply and directly disassembled into connecting beams and independent floating boxes that are convenient for transportation, thereby reducing the labor and material costs required during transportation. Moreover, the threaded structure has the advantage of being simple to disassemble and assemble, so the floating bridge can be conveniently disassembled and assembled, greatly improving the installation construction efficiency of the floating bridge.

[0006] According to some embodiments of the present invention, the frame includes two girders and a plurality of crossbeams parallel to each other. The two girders are respectively detachably connected to both ends of the crossbeams through threaded structures. The crossbeams are connected between the two girders, so that the area between the two girders can be filled, thereby supporting the bridge deck provided there. The connection of the threaded structure enables the girders and the crossbeams to be simply and directly installed and disassembled, thus facilitating disassembly and transportation or installation construction, and further reducing the labor and material costs required during transportation and installation.

[0007] According to some embodiments of the present invention, connection clamping plates are provided on the side walls of the girders, and first connection holes are provided on the connection clamping plates; connection flanges are provided at the ends of the crossbeams, and second connection holes are provided on the connection flanges. The first connection holes and the second connection holes are connected and fixed by bolts. The connection clamping plates can connect the ends of the crossbeams to the girders, thereby realizing their detachable installation. The connection clamping plates can not only provide a site for threaded installation for the connection of the crossbeams, but also cooperate with the side walls of the crossbeams to position the ends of the crossbeams, so as to align the first connection holes and the second connection holes, and further make the threaded connection process more convenient.

[0008] According to some embodiments of the present invention, one of the connection clamping plates and the crossbeams is provided with a clamping block, and the other is provided with a clamping groove, and the clamping block is stuck in the clamping groove. The cooperation of the clamping block and the clamping groove can not only enable the connection clamping plates and the crossbeams to be quickly positioned, but also prevent the two from moving and causing misalignment during the connection by bolts, and further ensure the stability of the bolt connection.

[0009] According to some embodiments of the present invention, the girders are surrounded by a plurality of connection walls, and the thickness of the connection clamping plates is greater than the thickness of the connection walls. The connection clamping plates are used to connect with the crossbeams. Since the thickness of the connection clamping plates is greater than the thickness of the connection walls, when subjected to an external force sufficient to cause deformation of the girders, the connection clamping plates have a higher anti-deformation ability relative to the connection walls. Therefore, the connection clamping plates are more difficult to deform, and further ensure that the connection clamping plates can be stably connected to the crossbeams and ensure the floating bridge is more stable.

[0010] According to some embodiments of the present invention, a deformation cavity is provided inside the crossbeams. When subjected to a large external impact, the deformation cavity will deform, thereby buffering the external impact, and further reducing the impact of the external impact on the connection plates. When one side of the crossbeam is impacted, the other side can still stably connect to the girder after being buffered by the deformation cavity. Therefore, the overall impact resistance of the crossbeam is higher.

[0011] According to some embodiments of the present invention, a plurality of keel beams are detachably connected to the cross beam. The keel beams intersect with the cross beam, and the bridge deck is laid on the keel beams. The keel beams can further fill the area between the two main beams, thereby stably supporting the bridge deck.

[0012] According to some embodiments of the present invention, a water and electricity cover plate is clamped to the side of the main beam. The water and electricity cover plate is located between the two main beams and can clamp the bridge deck between the water and electricity cover plate and the keel beam. The water and electricity cover plate cooperates with the keel beam to press and fix the bridge deck, so the stability of the bridge deck on the keel beam can be improved.

[0013] According to some embodiments of the present invention, a lapping part and an abutting part are provided on the keel beam. The lapping part of one of the plurality of keel beams is detachably connected to the abutting part of another. The plurality of keel beams can be connected pairwise, so as to more stably support the bridge deck, and thus can meet the use requirements of different scenarios.

[0014] According to some embodiments of the present invention, a plurality of reinforcing ribs are provided on the side of the floating box away from the frame. Some or all of the plurality of reinforcing ribs extend to the edge of the floating box, and some or all of the plurality of reinforcing ribs cross each other. By providing a plurality of reinforcing ribs, the rigidity and strength of the box body can be increased, thereby increasing the load-bearing stability of the box body. The crossed part of the reinforcing ribs can not only increase the load-bearing area, but also disperse and guide the gravity borne, so the load-bearing stability can be improved. Since some or all of the reinforcing ribs extend to the edge of the load-bearing surface, the reinforcing ribs are connected to the edge of the box body. When the side of the box body is impacted, the reinforcing ribs can also perform corresponding buffering, thereby enhancing the load-bearing stability of the box body.

[0037] Refer to Figure 1 , a detachable floating bridge, comprising: a frame 100, a floating box 300 and a bridge deck 200. The frame 100 includes a plurality of connecting beams, and some or all of the plurality of connecting beams are detachably connected to each other in pairs through a threaded structure; the floating box 300 is detachably connected to the lower part of the frame 100 through a threaded structure; the bridge deck 200 is laid on the frame 100. The connecting beams are connected into the frame 100 through a threaded structure, so the disassembly or assembly of the frame 100 can be simply realized by releasing the threaded connection, thereby changing the length, width and shape of the frame 100, etc., and then being applicable to different usage scenarios. At the same time, the floating box 300 is also connected to the frame 100 through a threaded structure. Therefore, only by releasing the threaded connections at various places can the disassembly of the floating bridge be realized, so that the formed floating bridge can be simply and directly disassembled into connecting beams and independent floating boxes 300 that are convenient for transportation, thereby reducing the labor and material costs required during transportation. Moreover, the threaded structure has the advantage of being simple to disassemble and assemble, so the disassembly and assembly of the floating bridge can be carried out conveniently, so as to greatly improve the installation and construction efficiency of the floating bridge.

[0038] In some embodiments, refer to Figure 2, the frame 100 includes two main girders 120 and a plurality of cross beams 130 that are parallel to each other. The two main girders 120 are detachably connected to both ends of the cross beam 130 through a threaded structure. The cross beam 130 is connected between the two main girders 120, so that the area between the two main girders 120 can be filled, thereby supporting the bridge deck 200 provided there. The connection of the threaded structure enables the main girder 120 and the cross beam 130 to be simply and directly installed and disassembled, thus facilitating disassembly and transportation or installation construction, and further reducing the labor and material costs required during transportation and installation.

[0039] In some embodiments, referring to Figure 3 , a connection clamping plate 123 is provided on the side wall of the main girder 120, and a first connection hole 125 is provided on the connection clamping plate 123; a connection flange 133 is provided at the end of the cross beam 130, and a second connection hole 135 is provided on the connection flange 133. The first connection hole 125 and the second connection hole 135 are connected and fixed by a bolt 900. The connection clamping plate 123 can connect the end of the cross beam 130 to the main girder 120, thereby realizing the detachable installation of the two. The connection clamping plate 123 can not only provide a threaded installation site for the connection of the cross beam 130, but also cooperate with the side wall of the cross beam 130 to position the end of the cross beam 130, so as to align the first connection hole 125 and the second connection hole 135, and further make the threaded connection process more convenient.

[0040] In some embodiments, referring to Figure 3 , one of the connection clamping plate 123 and the cross beam 130 is provided with a clamping block 124, and the other is provided with a clamping groove 134. The clamping block 124 is stuck in the clamping groove 134. The cooperation of the clamping block 124 and the clamping groove 134 can not only enable the connection clamping plate 123 and the cross beam 130 to be quickly positioned, but also prevent the two from moving and causing misalignment during the connection of the bolt 900, and further ensure the stability of the connection of the bolt 900. Specifically, the clamping block 124 is provided on the connection clamping plate 123126, and the clamping groove 134 is provided on the cross beam 130.

[0041] In some embodiments, referring to Figure 4 , the main girder 120 is surrounded by a plurality of connecting walls 121, and the thickness of the connection clamping plate 123 is greater than the thickness of the connecting wall 121. The connection clamping plate 123 is used to connect with the cross beam 130. Since the thickness of the connection clamping plate 123 is greater than the thickness of the connecting wall 121, when subjected to an external force sufficient to cause the main girder 120 to deform, the connection clamping plate 123 has a higher anti-deformation ability relative to the connecting wall 121. Therefore, the connection clamping plate 123 is more difficult to deform, and further ensures that the connection clamping plate 123 can be stably connected to the cross beam 130 and ensures the stability of the floating bridge.

[0042] In some embodiments, the thickness of the connecting card plate 123 is 6 mm - 20 mm. The range of 6 mm - 20 mm is a reasonable thickness value range obtained through testing. If the thickness of the connecting card plate 123 is less than 6 mm, problems such as notches or deformation are likely to occur due to the overly thin connecting card plate 123, and the lateral impact force that the overall profile can withstand is also reduced. If the thickness of the connecting card plate 123 is greater than 20 mm, there will be a problem of excessive cost. Therefore, the range of 6 mm - 20 mm is a reasonable thickness value range obtained through testing. Specifically, the thickness of the connecting card plate 123 is 10 mm. Through testing, it is found that the connecting card plate 123 with a thickness of 10 mm is in the best state in terms of load-bearing, wind load, water flow force, mooring force, squeezing force, or impact force.

[0043] In some embodiments, referring to Figure 4 , a plurality of friction teeth 126 are provided on the connecting wall 121. The friction teeth 126 can increase the relative friction force when the connecting wall 121 contacts the external structure, thereby making the connection with the remaining beam bodies more stable.

[0044] In some embodiments, referring to Figure 4 , a first locking groove 128 is provided at the bottom of the main beam 120, a second connection hole 135 is located at the bottom of the cross beam 130, and a bolt 900 is installed in the second connection hole 135 and part of the bolt 900 is stuck in the first locking groove 128. The first locking groove 128 can connect and lock the cross beam 130 from below, thereby connecting the cross beam 130 more firmly to the main beam 120.

[0045] In some embodiments, referring to Figure 2 , a front and rear connecting beam 160 is provided between two main beams 120. The front and rear connecting beam 160 is connected to the ends of the main beams 120, and the two main beams 120 are respectively threadedly connected to the two ends of the front and rear connecting beam 160. The front and rear connecting beam 160 can connect the ends of the two main beams 120, thereby connecting the two main beams 120 into a whole. Specifically, the bolt 900 passes through the front and rear connecting beam 160, and the head of the bolt 900 is installed in the first locking groove 128.

[0046] In some embodiments, referring to Figure 2 , a card slot 134 is provided on the front and rear connecting beam 160, and a card block 124 is provided on the connecting card plate 123, and the card block 124 is stuck in the card slot 134.

[0047] In some embodiments, referring to Figure 4 , a clamping portion 127 is provided on the main beam 120, and a buffer member 500 is clamped on the clamping portion 127. The buffer member 500 can reduce the impact force on the main beam 120 when the ship hits the floating bridge, thereby avoiding deformation or damage of the main beam 120. Specifically, the buffer member can be a fender.

[0048] In some embodiments, referring to Figure 4 , a first locking groove 128 is provided on the girder 120. Bolts 900 for connection can be provided in the first locking groove 128, so as to realize the mutual connection and combination of a plurality of girders 120, and further splice the girders 120 into a combined body with a larger size and greater strength to meet the usage requirements.

[0049] In some embodiments, referring to Figure 5 , a deformation cavity 137 is provided inside the cross beam 130. When subjected to a large external impact, the deformation cavity 137 will deform, so as to buffer the external impact, and further reduce the influence of the external impact on the connecting plate. When one side of the cross beam 130 is impacted, the other side can still stably connect to the girder 120 after the deformation cavity 137 buffers, so the overall impact resistance of the cross beam 130 is higher.

[0050] In some embodiments, referring to Figure 6 , the connecting flange 133 includes a first plate member and a second plate member. The first plate member and the second plate member are respectively arranged on the upper and lower parts of the cross beam 130, and the second connecting holes 135 are multiple and are respectively arranged on the first plate member and the second plate member. The first plate member and the second plate member can respectively connect the girder 120 to the upper and lower parts of the profile body, so that the connection points between the girder 120 and the cross beam 130 are increased, and further the connection is more stable, and it is difficult for external impacts to damage the connection between the cross beam 130 and the girder 120.

[0051] In some embodiments, referring to Figure 6 , the second plate member protrudes outward relative to the cross beam 130 in the front-rear direction. The girder 120 can be lapped on the protruding part of the second plate member, so as to obtain a positioning effect between the two, and further facilitate their connection.

[0052] In some embodiments, referring to Figure 2 , a plurality of keel beams 140 are detachably connected to the cross beam 130. The keel beams 140 intersect with the cross beam 130, and the bridge plate 200 is laid on the keel beams 140. The keel beams 140 can further fill the area between two girders 120, so as to stably support the bridge plate 200.

[0053] In some embodiments, referring to Figure 2 , a water and electricity cover plate 400 is clamped on the side of the girder 120. The water and electricity cover plate 400 is located between two girders 120 and can clamp the bridge plate 200 between the water and electricity cover plate 400 and the keel beam 140. The water and electricity cover plate 400 cooperates with the keel beam 140 to press and fix the bridge plate 200, so the stability of the bridge plate 200 on the keel beam 140 can be improved.

[0054] In some embodiments, referring to Figure 2 , the end of the keel beam 140 is connected to the front and rear connecting beams 160 by bolts 900.

[0055] In some embodiments, referring to Figure 7 , a lapping portion 143 and an abutting portion 147 are provided on the keel beam 140, and the lapping portion 143 of one of the plurality of keel beams 140 is detachably connected to the abutting portion 147 of another. The plurality of keel beams 140 can be connected in pairs, so as to provide a more stable support for the bridge deck 200, and thus can meet the usage requirements for different scenarios.

[0056] In some embodiments, referring to Figure 7 , a stepped position is formed between the lapping portion 143 and the abutting portion 147. The lapping portion 143 on another keel beam 140 can be lapped on this stepped position, so that the two connected keel frames 100 have the same height, and the pontoon bridge will not show unevenness, thereby improving the smoothness of the pontoon bridge.

[0057] In some embodiments, referring to Figure 7 , the abutting portion 147 is arranged at the lower part of the keel beam 140, and a supporting portion 145 for supporting the bridge deck 200 is arranged at the upper part of the keel beam. The supporting portion 145 and the abutting portion 147 are respectively located at the upper and lower parts of the keel beam 140, so that the problem of deformation and failure caused by excessive force on a single part of the keel beam 140 can be avoided. Specifically, the lower part of the abutting portion 147 is used to abut against the floating box 300, and the supporting portion 145 is used to abut against the bridge deck 200.

[0058] In some embodiments, referring to Figure 8 , among the two mutually connected keel beams 140, the end of one of them is lapped on the abutting portion 147 of the other. The lapping of the end and the side wall enables the relative angle between the two keel beams 140 to be adjusted, so that the range where the frame 100 can be laid on the horizontal plane becomes wider, and thus the area of the pontoon bridge is enlarged.

[0059] In some embodiments, referring to Figure 8 , among the two mutually connected keel beams 140, the abutting portion 147 of one of them is shorter than its lapping portion 143, and the end of this lapping portion 143 is lapped on the abutting portion 147 of another keel beam 140. The shortening of the abutting portion 147 enables a yielding effect to be generated during lapping, so as to ensure that the lapping portion 143 can be smoothly lapped and matched with the abutting portion 147 of another keel beam 140, thereby ensuring the overall stability of the frame 100.

[0060] In some embodiments, referring to Figure 9A plurality of reinforcing ribs 350 are provided on the side of the pontoon 300 away from the frame 100, and some or all of the plurality of reinforcing ribs 350 extend to the edge of the pontoon 300, and some or all of the plurality of reinforcing ribs 350 cross each other. By providing a plurality of reinforcing ribs 350, the rigidity and strength of the box body can be increased, thereby increasing the load-bearing stability of the box body. The cross-section of the reinforcing ribs 350 can not only increase the load-bearing area, but also disperse and guide the gravity borne, thereby improving its load-bearing stability. Since some or all of the reinforcing ribs 350 extend to the edge of the load-bearing surface, the reinforcing ribs 350 are connected to the edge of the box body. When the side of the box body is impacted, the reinforcing ribs 350 can also perform corresponding buffering, thereby improving the load-bearing stability of the box body.

[0061] In certain embodiments, reference Figure 9 The reinforcing ribs 350 intersect each other at the center of the load-bearing surface of the pontoon 300. Since the intersection of the two reinforcing ribs 350 is located at the center of the load-bearing surface of the pontoon 300, the center of the pontoon 300 has higher load-bearing stability, and the gravity received by the center of the pontoon 300 can be evenly distributed to the edge, thereby improving the stability of the pontoon 300 when subjected to force.

[0062] In certain embodiments, reference Figure 9 The load-bearing surface is a rectangular surface, and the two intersecting reinforcing ribs 350 are respectively located on the two diagonals of the load-bearing surface. The reinforcing ribs 350 are arranged at the diagonals of the load-bearing surface, so that the entire load-bearing surface can be evenly loaded, thereby improving the load-bearing stability of the pontoon 300. In addition, the reinforcing ribs 350 are symmetrically distributed on the load-bearing surface, which can avoid affecting the shrinkage of the plastic, thereby preventing uneven deformation of the plastic pontoon 300 and the corresponding stress concentration problem, and avoiding damage to the pontoon 300.

[0063] In certain embodiments, reference Figure 9 A plurality of support platforms 310 are arranged on the load-bearing surface, and the support platforms 310 are located in the middle of the edge of the pontoon 300. The support platforms 310 can support the staggered parts of the reinforcing ribs 350, thereby increasing the load-bearing surface of the pontoon 300 to the connecting beam, thereby improving the load-bearing stability of the pontoon 300.

[0064] In certain embodiments, reference Figure 9 A plurality of reinforcing grooves 320 are provided on the side wall of the pontoon 300, and the reinforcing grooves 320 are concave relative to the side wall of the pontoon 300 to form a rib structure on the inner wall of the pontoon 300. The second reinforcing ribs 350 can increase the rigidity and strength of the side wall of the pontoon 300, thereby increasing the load-bearing stability of the pontoon 300.

[0065] In certain embodiments, reference Figure 9, the reinforcing groove 320 is located in the middle of the side wall of the floating box 300. The second reinforcing ribs 350 are evenly and symmetrically distributed in the floating box 300, which can not only support the bearing surface evenly from all directions, but also avoid affecting the shrinkage of the plastic, thus preventing uneven deformation and corresponding stress concentration problems of the plastic floating box 300 and avoiding damage to the shape.

[0066] In some embodiments, referring to Figure 9 , a plurality of third connection holes 370 are provided on the floating box 300, and the third connection holes 370 and the first connection holes 125 are connected by bolts 900. The opposite sides of the floating box 300 are connected to the two girders 120 by bolts 900, which not only enables a single floating box 300 to firmly support the frame 100 in the width direction, but also the floating box 300 can play a role in lateral support, thereby improving the stability of the floating bridge.

[0067] In some embodiments, the floating box 300 includes a frame (not shown in the figure), concrete poured on the frame, and plastic foam filled in the concrete (not shown in the figure). The concrete has excellent waterproofing ability, so it can effectively prevent water from contacting the frame and the plastic foam, thereby improving the service life and stability of the floating box 300.

[0068] In some embodiments, additives with coagulation-promoting and densifying effects, such as waterproofing agents, air-entraining agents, and expansion agents, are added to the concrete. The additives can enhance the hydrophobicity and impermeability of the cement mortar and concrete, thus ensuring that the concrete has a high waterproofing ability.

[0069] In the description of this specification, the description of reference terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0070] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
