Description

[0002] At present, steel box girder support structures are key components in bridge construction, which are used to support steel box girders and ensure their stability. In traditional steel box girder support structures, no limiting devices are usually provided on both sides of the support structure, so that the steel box girder is prone to skewing during hoisting and installation. Such skewing not only increases the workload of subsequent angle adjustment, but also brings difficulties to the accurate installation of the steel box girder, affecting the construction efficiency and the stability of the bridge structure. Therefore, the existing steel box girder support structure has obvious deficiencies in ensuring the correct installation of the steel box girder and the safety of the bridge.

[0012] In some embodiments, the support body is provided with sliding grooves which are arranged in cooperation with the limiting blocks, and the number of the sliding grooves is equal to the number of the limiting blocks, so as to carry the limiting blocks and enable the limiting blocks to slide along the tracks of the sliding grooves.

[0013] In some embodiments, the first abutting end is a limiting through groove which is in communication with the corresponding sliding groove, and the connecting piece is a limiting screw, and the limiting through groove penetrates the support body in the thickness direction, so that the limiting screw can pass through the limiting through groove and be inserted into the insertion hole arranged on the limiting block.

[0015] In some embodiments, the steel box girder is provided with at least two second abutting ends which are arranged on the side or bottom of the steel box girder along the length direction of the steel box girder.

[0016] The second limiting end is arranged on the side wall of the support body, and the upper side end of the second limiting end is higher than the upper surface of the support body, so that the upper side end of the second limiting end can be connected with the second abutting end.

[0017] In some embodiments, the second limiting assembly comprises a body fixing block and a plurality of fixing pieces, and the second limiting end is a rod-shaped structure, wherein the body fixing block is fixed to the side wall of the support body, and a through hole is formed in the center of the body fixing block, so that the second limiting end can pass through the through hole on the body fixing block and be fixedly connected to the body fixing block through the fixing pieces.

[0018] In the installed state, the second limiting end is connected with the corresponding second butt joint end, thereby limiting the relative displacement between the steel box girder and the support body.

[0025] Compared with the prior art, the steel box girder support structure provided by the present application has at least one of the following beneficial effects:

[0026] 1. By designing the first limiting assembly and the second limiting assembly, the steel box girder can be accurately limited in the width and length directions, ensuring that the steel box girder maintains the correct position and angle during hoisting and installation, reducing the possibility of skewing. At the same time, the movable connection design of the first limiting assembly allows the operator to adjust the position of the limiting end according to the actual width of the steel box girder, improving the flexibility and adaptability of the installation process.

[0027] 2. Through the threaded connection of the limit screw and the limit nut, the operator can quickly unlock and lock the limit block by turning the limit nut. At the same time, the position of the limit block can be precisely adjusted to adapt to steel box girders of different widths, achieving precise width-direction limiting and improving the efficiency of installation and adjustment.

[0028] 3. By arranging at least two second mating ends along the length of the steel box girder on its side or bottom, and setting second limiting ends on the side walls of the support structure, an effective connection can be formed with the second mating ends of the steel box girder. This design not only enhances the stability of the steel box girder in the length direction, but also improves the rigidity and reliability of the entire support structure.

[0029] 4. The uniform support of multiple supporting bodies ensures that the steel box girder is subjected to uniform support force along its entire length. This helps to avoid deformation or stress concentration of the steel box girder due to uneven support force. Moreover, the uniformly distributed supporting bodies provide multiple support points, which increases the stability of the structure. Especially when subjected to large loads or under the action of external forces such as wind loads and earthquakes, the stability of the steel box girder can be better maintained.

[0042] In bridge engineering, steel box girder as a common long-span bridge structure form, its stability and accurate installation are crucial to the safety and functionality of the whole bridge. Steel box girder is usually connected by full welding of top plate, bottom plate, web plate, transverse diaphragm, longitudinal diaphragm and stiffening rib and other components, with wide and flat shape characteristics. However, in the existing steel box girder support structure, a significant problem is the lack of effective limiting device. This deficiency leads to the steel box girder prone to deviation during lifting and installation, resulting in a decrease in positioning accuracy, and thus affecting the overall construction quality of the bridge.

[0043] Specifically, the conventional steel box girder support structure fails to provide sufficient limiting devices on the piers or support bodies to resist and limit the displacement of the steel box girder in the transverse or longitudinal direction. Under the action of external forces such as earthquakes, this structure lacking limiting devices may cause the steel box girder to collide with the piers, resulting in excessive transverse displacement of the girder body, even bearing failure, which seriously threatens the safety and stability of the bridge.

[0044] In one embodiment, referring to the drawings attached hereto Figure 1 , a steel box girder support structure is provided, which can provide stable support and accurate limiting during the lifting and installation of the steel box girder 1, to ensure the correct position and angle of the steel box girder 1, reduce the adjustment work in construction, improve the construction efficiency, and enhance the stability and durability of the bridge structure.

[0045] In one embodiment, referring to the drawings attached hereto Figure 1 , a steel box girder support structure is provided, which can provide stable support and accurate limiting during the lifting and installation of the steel box girder 1, to ensure the correct position and angle of the steel box girder 1, reduce the adjustment work in construction, improve the construction efficiency, and enhance the stability and durability of the bridge structure.

[0046] As shown in Figure 2 and Figure 4 , the first limiting assembly 3 is movably connected to the support body 2 and includes a plurality of first limiting ends 31, which are operable to move along the width direction of the steel box girder 1 to abut to the corresponding two side walls of the steel box girder 1 respectively, to realize limiting in the width direction. The second limiting assembly 4 is at least partially provided on the support body 2 and includes at least two second limiting ends 41, which are provided on both sides of the support body 2 in the length direction, and in the installed state, the second limiting ends 41 are respectively connected to the predetermined positions of the steel box girder 1, to realize limiting in the length direction.

[0047] It can be understood that through the cooperative action of the first limiting assembly 3 and the second limiting assembly 4, the steel box girder 1 can be accurately limited in two main directions, to ensure that the steel box girder 1 maintains the correct position and angle during lifting and installation, reduces the possibility of skew, and thus improves the installation accuracy.

[0048] In actual application, the position of the support body 2 is determined according to the bridge design requirements, and is fixed at the preset position. The operator can adjust the position of the first limiting end 31 according to the actual width of the steel box girder 1, so that it can be accurately abutted to the two side walls of the steel box girder 1, realizing the limiting in the width direction. At the same time, when the steel box girder 1 is hoisted to above the support body 2, the operator will butt the second limiting end 41 with the preset position of the steel box girder 1, realizing the limiting in the length direction.

[0049] Optionally, a guide rail is installed on the support body 2, and the first limiting end 31 is connected with a sliding block which slides on the guide rail to realize the adjustment along the width direction of the steel box girder 1. The guide rail can be linear or curved to adapt to different installation requirements. After sliding in place, the position of the first limiting end 31 is locked by a locking piece, thereby forming the limiting effect. Alternatively, the first limiting end 31 is connected with the support body 2 through a telescopic connecting component, such as a telescopic joint or a telescopic sleeve, allowing the first limiting end 31 to be telescopic along the width direction of the support body 2 to adapt to steel box girders 1 of different widths.

[0050] In addition, in the present embodiment, the second limiting end 41 can be directly designed to abut against the side wall of the steel box girder 1 to prevent the steel box girder 1 from deviating in the length direction. Of course, the second limiting end 41 can also be butt-locked with some preset structures on the steel box girder 1.

[0051] In one embodiment, as shown in Figure 1 The number of support bodies 2 is two or more, and the support bodies 2 are uniformly distributed along the same straight line to provide overall support for the steel box girder 1. In other words, by providing multiple support points, the stability of the structure is increased. Each support body 2 includes a support column 22 and a load-bearing base 21. The support column 22 is fixed at a preset position, and the load-bearing base 21 is fixed at the bottom of the support column 22.

[0052] The first limiting end 31 and the second limiting end 41 are respectively arranged on the load-bearing base 21, ensuring that the limiting ends can accurately cooperate with the butt ends on the steel box girder 1 during hoisting and installation of the steel box girder 1, realizing accurate limiting.

[0053] Optionally, as shown in the figure, in each support body 2, the number of support columns 22 can be one or more. When the number of support columns 22 is more than one, they are uniformly connected to the bottom of the load-bearing base 21 at a preset interval, enhancing the stability and load-bearing capacity of the entire support structure.

[0054] Based on the above embodiments, reference can be made to the accompanying drawings Figure 2At least two first limiting ends 31 are symmetrically arranged on each load-bearing base 21. In the installed state, the interval between the two first limiting ends 31 is at least equal to the width of the steel box girder 1, so that the opposite two side edges of the steel box girder 1 can be limited between the corresponding two first limiting ends 31, ensuring the stability and alignment accuracy of the steel box girder 1 during hoisting and installation.

[0055] In one embodiment, as shown in Figure 2 , a plurality of first docking ends 201 are arranged on the support body 2, which can match the first limiting ends 31.

[0056] Further, as shown in Figure 3 , the first limiting end 31 includes a limiting block 311 and a connecting piece 312 arranged in cooperation with the limiting block 311, and each limiting block 311 corresponds to at least one connecting piece 312. The connecting piece 312 is connected to the first docking end 201 in the installed state, realizing the abutment of the limiting block 311 and the side wall of the steel box girder 1, thereby limiting the steel box girder 1 in the width direction.

[0057] It should be noted that in the present embodiment, the corresponding connection of the first docking end 201 and the first limiting end 31 can realize the accurate limiting of the side wall of the steel box girder 1. The cooperation of the limiting block 311 and the connecting piece 312 ensures that the side wall of the steel box girder 1 can be stably supported and limited during installation, preventing lateral deviation during hoisting or use.

[0058] In addition, a plurality of limiting blocks 311 can simultaneously limit different positions of the steel box girder 1, providing multiple support points, enhancing the stability of the entire support structure, helping to distribute the weight of the steel box girder 1 and reducing the pressure on a single support point.

[0059] Meanwhile, in the present embodiment, at least one connecting piece 312 is arranged on each limiting block 311, and the number and specific position of the connecting piece 312 on the limiting block 311 are determined according to multiple factors such as the shape, size of the limiting block 311 and the arrangement form of the first docking end 201. The position of the connecting piece 312 on the limiting block 311 can be adjusted as needed to adapt to different arrangement forms of the first docking end 201.

[0060] Based on the present embodiment, optionally, as shown in Figure 3 , the limiting block 311 is designed as an L-shaped cross section, which allows the limiting block 311 to simultaneously fit the side wall and the bottom wall of the steel box girder 1.

[0061] It can be understood that the L-shaped section of the limiting block 311 increases the contact area with the steel box girder 1, thereby improving the stability of the overall structure. This design reduces the possibility of deviation of the steel box girder 1 during hoisting, improving the safety of construction.

[0062] In one embodiment, the steel box girder support structure further comprises a first locking mechanism that simultaneously interfaces with the first interface end 201 and the first limiting end 31, allowing the first interface end 201 and the first limiting end 31 to be fixed relative to each other, thereby limiting the position of the limiting block 311 on the support body 2, ensuring that the limiting block 311 will not be displaced due to external forces, improving the safety of construction.

[0063] In actual construction, the first locking mechanism can be implemented in various ways. For example, it can be designed as a system including a bolt, a nut and a washer, wherein the bolt passes through the corresponding holes of the first interface end 201 and the first limiting end 31, and the locking is achieved by tightening the nut.

[0064] In another embodiment, the first locking mechanism can be a buckle system, which quickly locks the positions of the first interface end 201 and the first limiting end 31 after they are aligned, improving the flexibility and adaptability of the first locking mechanism, which can be adjusted according to specific construction conditions and design requirements.

[0065] Optionally, the first locking mechanism can be equipped with an intelligent monitoring system to monitor the position and locking state of the limiting block 311 in real time, ensuring that the correct limiting can be maintained at any time.

[0066] Based on the above embodiments, further, the support body 2 is provided with sliding grooves 202, which are arranged in cooperation with the limiting blocks 311. Specifically, the number of sliding grooves 202 is equal to the number of limiting blocks 311, ensuring that each limiting block 311 has a corresponding sliding groove 202. This design allows the limiting block 311 to slide along the trajectory of the sliding groove 202, thereby achieving flexible positioning and adjustment on the support body 2.

[0067] It can be understood that through the sliding groove 202, the operator can accurately adjust the position of the limiting block 311 to achieve accurate limiting of the steel box girder 1, simplifying the operation process and ensuring the stability and safety of the steel box girder 1 during hoisting and installation.

[0068] In addition, in order to improve wear resistance and prolong service life, anti-wear materials can be added to the contact surface between the sliding groove 202 and the limiting block 311. These materials can be materials with high hardness and strong wear resistance, such as tungsten carbide, ceramic, high-speed tool steel or special alloy, thereby reducing wear caused by long-term friction and prolonging the service life of the structure.

[0069] In one embodiment, the first docking end 201 is a limiting through slot, and the connecting piece 312 is a limiting screw rod. The limiting through slot and the corresponding sliding slot 202 are connected in communication, so that the limiting screw rod can pass through the limiting through slot and be inserted into the insertion hole provided on the limiting block 311, thereby realizing the relative connection between the limiting block 311 and the support body 2.

[0070] Specifically, as shown in Figure 3 The first locking mechanism includes a plurality of limiting nuts 5. The inner thread of each limiting nut 5 is matched with the outer thread of the corresponding limiting screw rod. By screwing the limiting nut 5, the limiting nut 5 can slide along the limiting screw rod, thereby adjusting the position of the limiting block 311. When it is necessary to fix the position of the limiting block 311, the limiting nut 5 is screwed until it is pressed against the support body 2. When it is necessary to adjust the position of the limiting block 311, the limiting nut 5 is simply unscrewed in the opposite direction, so that the limiting block 311 can be easily unlocked and moved.

[0071] Furthermore, in order to ensure the stability and uniformity of force of the limiting block 311, two limiting screw rods are correspondingly connected to each limiting block 311, and the two limiting screw rods are symmetrically distributed on the two sides of the limiting block 311. Such a design enables the limiting block 311 to maintain balance when subjected to force, thereby reducing the deviation or deformation caused by unilateral force. Correspondingly, the limiting through slots on the support body 2 are also provided in two, which are respectively connected in communication with the two limiting screw rods, allowing the limiting screw rods to pass through the limiting through slots and be inserted into the insertion holes on the limiting block 311. On the other hand, in this embodiment, the double-screw rod design provides double protection. Even if one side of the screw rod fails or loosens, the other side of the screw rod can still fix the limiting block 311, thereby enhancing the stability of the entire structure.

[0072] In one embodiment, the steel box girder 1 is provided with at least two second docking ends 11, which are arranged on the side or bottom of the steel box girder 1 along the length direction of the steel box girder 1, so that the steel box girder 1 forms a plurality of connection points with the support body 2 in the length direction, thereby increasing the flexibility and stability of the connection.

[0073] The second limiting end 41 is arranged on the side wall of the support body 2, and the upper side end of the second limiting end 41 is higher than the upper surface of the support body 2, so as to ensure that the upper side end of the second limiting end 41 can form effective connection with the second docking end 11 on the steel box girder 1. It can be understood that the upper side end of the second limiting end 41 is higher than the upper surface of the support body 2, so that the steel box girder 1 can be directly docked with the second limiting end 41 during hoisting, thereby simplifying the hoisting and positioning process and improving the construction efficiency.

[0074] Optionally, the upper end of the second limiting end 41 is higher than the upper surface of the support body 2, so that the steel box girder 1 can be directly connected with the second limiting end 41 during hoisting, simplifying the hoisting and positioning process and improving the construction efficiency. Alternatively, the second connecting end 11 can be designed as a clamp structure with a clamping end, so that the second limiting end 41 can be clamped into the clamping end to form a fixed connection, thereby facilitating the quick and accurate fixing of the steel box girder 1 on the support body 2 during hoisting.

[0075] In one embodiment, as shown in Figure 4 The second limiting end 41 is designed as a rod structure, wherein the body fixing block 42 is fixed to the side wall of the support body 2, and a through hole is formed in the center of the body fixing block 42. This design allows the second limiting end 41 to pass through the through hole on the body fixing block 42 and be fixedly connected with the body fixing block 42 through the fixing members 43. In the installed state, the second limiting end 41 is connected with the corresponding second connecting end 11, thereby limiting the relative displacement between the steel box girder 1 and the support body 2 and ensuring the stability and accurate positioning of the steel box girder 1.

[0076] It can be understood that the structure of the body fixing block 42 and the fixing members 43 enhances the fixing strength of the second limiting end 41, ensuring that the connection between the steel box girder 1 and the support body 2 will not loosen under a large load. On the other hand, the through hole design of the body fixing block 42 makes the installation of the second limiting end 41 simple and fast. Only the rod structure needs to be passed through the through hole and fixed with the fixing members 43 to realize the connection between the second limiting end 41 and the body fixing block 42.

[0077] Among them, the rod structure of the second limiting end 41 provides a flexible connection method, which can be clamped or directly inserted into the second connecting end 11. Both can quickly position and fix the steel box girder 1, reduce the hoisting time, simplify the installation process, and improve the construction efficiency.

[0078] Based on the above embodiment, further, the second limiting assembly 4 further includes a beam body fixing block 44, and the second limiting end 41 is a limiting abutting screw, and the fixing member 43 is a fixing nut.

[0079] Among them, the beam body fixing block 44 is fixed to the bottom of the steel box girder 1, and a through hole is formed in the center of the beam body fixing block 44, thereby forming the second connecting end 11 together with the steel box girder 1. In the installed state, the limiting abutting screw is fixed to the body fixing block 42 through the fixing nuts, and the side end thereof is inserted into the through hole of the beam body fixing block 44, realizing the relative connection between the second limiting end 41 and the second connecting end 11.

[0080] It should be noted that in the embodiment, the fixing nuts can be tightened or loosened from the upper end and the lower end of the main body fixing block 42 to the direction of the main body fixing block 42 to achieve the position fixing or adjustment of the limiting abutting screw. In addition, in order to provide multiple fixing points and enhance the stability of the entire structure, two or more main body fixing blocks 42 can be provided, and the number of fixing nuts can be increased accordingly.

[0081] In addition, since the relative position between the limiting abutting screw and the main body fixing block 42 can be adjusted, by rotating the fixing nut, the limiting abutting screw can be inserted into the through hole of the beam body fixing block 44 at different depths to adapt to the steel box girder 1 under different installation conditions.

[0082] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should be considered as the protection scope of the present application.
