Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a steel truss installation system. Background Art

[0002] In the bridge industry, there are many different bridge types, and steel truss bridges are one of the most widely used bridge types due to their diverse structural forms, large spans, and high load-bearing capacity. Steel trusses are trussed steel and used as the primary load-bearing components in industrial and civil building roof structures, crane beams, bridges, and hydraulic gates. Various towers, such as masts, television towers, and transmission line towers, often utilize spatial steel trusses composed of three, four, or more planar trusses.

[0003] The inventors have discovered that the construction of existing steel truss bridges has at least the following shortcomings:

[0004] The main span of a steel truss bridge is designed as a hollow structure, with an upper beam and a lower beam installed within it. The upper beam is located above the lower beam, and both beams extend across the width of the main span. The lower beam passes through the main truss of the steel truss bridge, creating a cross-section between the two. Traditionally, the main truss is installed on the lower beam using a hoisting method, which is prone to interference, making construction difficult, posing safety risks, and inefficient.

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0040] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0042] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0043] In the prior art, when installing a steel truss on a main bridge in which a crossbeam 011 is provided in a hollow structure, the integral steel truss is directly hoisted into the hollow structure of the main bridge. Since the steel truss needs to pass through the main bridge, interference occurs between the crossbeam 011 in the hollow structure and the steel truss, which is prone to collision. This results in a high safety risk in construction and low construction efficiency.

[0044] In view of this, the designer provides a steel truss installation system that can reduce construction difficulty, reduce the probability of interference between the steel truss and the beam 011, and improve construction safety and efficiency.

[0045] Please combine Figure 1It should be noted that the steel truss installation system is used to install the steel truss main body 002 on the bridge body 001. Bridge body 001 is configured as a hollow structure, that is, bridge body 001 is provided with an installation channel. The installation channel is provided with two crossbeams 011 extending in the width direction of bridge body 001. The two crossbeams 011 are arranged at intervals in the length direction of bridge body 001. Bridge body 001 has two inner sidewalls arranged in the width direction of the bridge body. Each inner sidewall is provided with a support bracket 012 located below the crossbeam 011. A pad stone 013 is located in the middle position above the support bracket 012.

[0046] Meanwhile, the steel truss body 002 includes three units, each of which includes an upper chord 024, a lower chord 025, and a connecting beam 026 connecting the upper chord 024 and the lower chord 025. For ease of description, the three units are the first side span 021, the middle side span 022, and the second side span 023. The middle side span 022 also includes a first oblique beam 027 and a second oblique beam 028. The ends of the first oblique beam 027 and the second oblique beam 028 are both connected to the lower chord 025 of the middle side span 022 and are located on both sides of the connecting beam 026. The other ends of the first oblique beam 027 and the second oblique beam 028 are respectively connected to the upper chords 024 of the first side span 021 and the second side span 023.

[0047] When the steel truss installation system is used to install the steel truss main body 002 to a set position on the bridge body 001, the steel truss main body 002 is divided into multiple units and installed successively, thereby reducing construction difficulty and improving construction safety.

[0048] Please combine Figures 1-4 In this embodiment, the steel truss installation system includes a first support frame 100 and a second support frame 200 distributed on both sides of the bridge body 001. The first support frame 100 includes a load-bearing frame 110 and a first guide rail 120. The load-bearing frame 110 is erected on the first side of the bridge body 001, and the first guide rail 120 is installed on the top of the load-bearing frame 110 and abuts against one side of the corbel 012; the second support frame 200 includes a first split frame 210, a second split frame 220 and a second guide rail 230. The first split frame 210 is overlapped on the second side of the bridge body 001, and the second split frame 220 is detachably matched with the side of the first split frame 210 away from the first split frame 210. The second guide rail 230 is connected to the top of the first split frame 210 and the second split frame 220, and the second guide rail 230 abuts against the other side of the corbel 012.

[0049] Based on the above, the operation method of the steel truss installation system provided in this embodiment is as follows:

[0050] First, the first support frame 100 and the first split frame 210 are respectively set up on both sides of the bridge body 001. The first guide rail 120 on the first support frame 100 is overlapped on the corbel 012 and the end thereof abuts against one side of the pad stone 013. Correspondingly, the second guide rail 230 of the first split frame 210 is overlapped on the corbel 012 and the end thereof abuts against the other side of the pad stone 013. In this way, the first guide rail 120, the pad stone 013 and the second guide rail 230 cooperate to form a guide structure. The lower chord 025 of the middle side span 022 is lifted onto the first guide rail 120 on the first side of the bridge body 001 using the lifting equipment 003. One end of the first oblique beam 027 is then mounted on the lower chord 025. The lower chord 025 is then pulled using a rope or jack, causing the lower chord 025 and the first oblique beam 027 to slide in a first direction toward the cross beam 011. The distance between the first oblique beam 027 and the cross beam 011 is controlled to be between 3 and 5 cm, allowing the lower chord 025 of the middle side span 022 to move onto the second guide rail 230, facilitating the lifting and installation of the second oblique beam 028 on the second side of the bridge body 001. Furthermore, since the 3-5 cm distance between the first oblique beam 027 and the cross beam 011 is maintained, collision between the first oblique beam 027 and the cross beam 011 can be avoided. Next, on the second side of the bridge body 001, the second oblique beam 028 is lifted using the lifting equipment 003, and the second oblique beam 028 is installed on the lower chord 025 of the middle side span 022. In this way, the first oblique beam 027 and the second oblique beam 028 are respectively located on both sides of the cross beam 011.

[0051] Next, the lower chord 025 of the middle side span 022 is slid in the second direction until the middle of the lower chord 025 substantially overlaps the middle of the pad stone 013. At this point, the distance between the first diagonal beam 027 and one of the crossbeams 011 is equal to the distance between the second diagonal beam 028 and the other crossbeam 011, i.e., the middle side span 022 is centered. It should be understood that since the second split frame 220 does not engage with the first split frame 210 when the second diagonal beam 028 is initially hoisted, a larger space is freed up for the hoisting equipment 003 to move. The hoisting equipment 003 can be moved closer to the first split frame 210, facilitating the hoisting of the second diagonal beam to the lower chord 025 of the middle side span 022 and facilitating the installation of the second diagonal beam.

[0052] After adjusting the position of the middle side span 022, the hoisting equipment 003 is used to continue hoisting the connecting beam 026 of the middle side span 022 from the second side of the bridge body 001. Connecting beam 026 is lowered between the two crossbeams 011, connecting the bottom of connecting beam 026 to the lower chord 025. Similarly, because the second split frame 220 is not mounted on the first split frame 210, the hoisting equipment 003 has ample room for maneuver, making the hoisting operation easier. Next, the hoisting equipment 003 is used to hoist the upper chord 024 of the middle side span 022 from the second side of the bridge body 001 and connect it to the top of connecting beam 026. Upper chord 024 is located above the two crossbeams 011. The installation of the middle side span 022 is now complete.

[0053] Then, the first side span section 021 is installed, the first side span section 021 is lifted from the first side of the bridge body 001, and the upper chord 024 of the first side span section 021 is connected to the upper chord 024 of the middle side span section 022, the lower chord 025 of the middle side span section 022 is connected to the lower chord 025 of the first side span section 021, and the first oblique beam 027 is connected to the upper chord 024 of the first side span section 021.

[0054] Finally, the second side span section 023 is installed. First, the second split frame 220 is installed on the side of the first split frame 210 away from the bridge body 001. In this way, the support area of ​​the second support frame 200 is increased, which is conducive to supporting the second side span section 023. During construction, the second side span section 023 is lifted from the second side of the bridge body 001, and the upper chord 024 of the second side span section 023 is connected to the upper chord 024 of the middle side span section 022, and the lower chord 025 of the middle side span section 022 is connected to the lower chord 025 of the second side span section 023, and the first oblique beam 027 is connected to the upper chord 024 of the second side span section 023. At this point, the installation of the steel truss main body 002 and the bridge body 001 is completed.

[0055] During the installation process, the steel truss body 002 is split into multiple units and installed separately, which reduces the construction difficulty, reduces the probability of collision between the steel truss body 002 and the beam 011, and improves construction safety.

[0056] It should be understood that after the bridge construction is completed, the first support frame 100 and the second support frame 200 are removed, and wind-resistant bearings and other structures are provided on the corbels 012 to support the lower chord 025 of the middle side span 022.

[0057] The following embodiments illustrate the detailed structure of the steel truss installation system provided in this application by way of examples.

[0058] Please combine Figures 1-4In this embodiment, optionally, the first support frame 100 further includes concrete piles. The load-bearing frame 110 includes a plurality of first vertical support columns 111 and a plurality of first transverse support columns 112. At least some of the plurality of first vertical support columns 111 are fixed to the concrete piles; the plurality of first transverse support columns 112 are connected to the plurality of first vertical support columns 111. By providing the concrete columns 130, the supported position of the load-bearing frame 110 can be adjusted as needed, the support firmness of the load-bearing frame 110 can be increased, the load-bearing frame 110 can be adapted to different on-site environments, and the construction flexibility can be improved.

[0059] It should be understood that the number of first vertical support columns 111 and first transverse support columns 112 can be set as needed. The first vertical support columns 111 and first transverse support columns 112 are arranged vertically and crosswise, and can be installed at the intersection using steel fasteners. In addition, to improve stability, a first diagonal support column 113 is also provided between the first vertical support columns 111 and the first transverse support columns 112.

[0060] In this embodiment, optionally, the load-bearing frame 110 also includes a stabilizing sleeve, which includes a base plate and multiple reinforcement plates. The base plate is fixedly connected to the bottom end of the first vertical support column 111, and the multiple reinforcement plates are arranged around the first vertical support column 111. Each reinforcement plate is fixedly connected to the base plate and the first vertical support column 111 at the same time.

[0061] It should be understood that the stabilizing sleeve can increase the contact area between the first vertical support column 111 and the supported surface, such as the ground or the top surface of the concrete column 130, thereby improving the installation firmness of the first vertical support column 111. The first vertical support column 111 can provide stable support and ensure the stability of the position of the first guide rail, thereby improving the safety of the construction process.

[0062] In this embodiment, the first guide rail 120 optionally includes two first rail bodies 121 arranged opposite each other and a plurality of first connecting sleeves 122. A first running wheel assembly is disposed on the top of each first rail body 121, and a first baffle 123 is disposed on the outside of the first rail body 121. Multiple first connecting sleeves are mounted below each first rail body 121, and each of the first connecting sleeves is respectively sleeved onto the top of a corresponding first vertical support column 111. The first connecting sleeves may be steel sleeves, which provide high structural strength and a long service life.

[0063] It should be understood that by cooperating with the two first rail bodies 121 to guide the steel truss body 002, the steel truss body 002 is more stable and less likely to deviate when sliding relative to the first rail body 121, thereby enhancing construction safety. Furthermore, the first rail body 121 is plugged into and mated with the first vertical support column 111 via the first connecting sleeve, simplifying assembly and increasing assembly efficiency. The first baffle 123 limits the range of deflection of the steel truss body 002 when sliding relative to the first rail body 121, preventing the steel truss body 002 from sliding off the first rail body 121 and ensuring construction safety.

[0064] Optionally, at least a portion of the first baffles 123 is configured to be tilted outward, so that the distance between the two first baffles 123 gradually decreases from top to bottom. Since the first baffles 123 are tilted relative to the first rail body 121, when the steel truss body 002 is hoisted onto the first rail body 121 using the hoisting equipment 003, the steel truss body 002 can be smoothly supported by the first rail body 121 under the guidance of the first baffles 123 on both sides. In other words, the first baffles 123 serve to guide the steel truss body 002 to its lower position, shortening the time it takes for the steel truss body 002 to cooperate with the first rail body 121 and improving hoisting efficiency.

[0065] In this embodiment, optionally, the ends of some of the first transverse support columns 112 of the load-bearing frame 110 can abut against one side surface of the corbel 012. The load-bearing frame 110 cooperates with the corbel 012 to improve the stability of the load-bearing frame 110, thereby enabling the load-bearing frame 110 to provide stable support and improve construction safety.

[0066] In this embodiment, the second guide rail 230 can optionally be configured as a retractable structure. The length of the second guide rail 230 can be adjusted as needed to accommodate different construction scenarios, providing flexibility and convenience. For example, when only the first split frame 210 is installed, the length of the second guide rail 230 can be shortened to accommodate the length of the first split frame 210. When the second split frame 220 is assembled with the first split frame 210, the length of the second guide rail 230 can be increased so that it can be distributed across the top of the second split frame 220, facilitating the bearing and sliding of the second side span 023.

[0067] For example, the second guide rail 230 includes multiple guide units, each of which includes a second rail body 231 and multiple second running wheel assemblies. Multiple guide units are arranged side by side, and the second rail bodies 231 of adjacent guide units are detachably connected. By selecting the number of guide units and splicing a corresponding number of guide units together, a second guide rail 230 of a corresponding length can be obtained, thereby adapting to different construction scenarios and facilitating adjustment. A second connection kit 235 can be installed at the bottom of the second rail body 231, and the second connection kit 235 plugs into the second vertical support column 211.

[0068] Furthermore, a first connecting flange 233 and a second connecting flange 234 are provided on both sides of the second rail body 231, and the first connecting flange 233 and the second connecting flange 234 of adjacent second rail bodies 231 are fixedly connected by bolts.

[0069] It should be understood that a second baffle 232 may be provided on the outer side of the second rail body 231 , and the structure of the second baffle 232 may be the same as that of the first baffle 123 .

[0070] In this embodiment, the first split frame 210 or the second split frame 220 optionally includes a second vertical support column 211 and a second transverse support column 212, wherein the second vertical support column 211 and the second transverse support column 212 are fixedly connected, and the second guide rail 230 is connected to the top of the second vertical support column 211. The first split frame 210 and the second split frame 220 have a simple structure and are easy to manufacture. To improve the connection strength, the first split frame 210 or the second split frame 220 may further include a second diagonal support column 213 that simultaneously connects the second vertical support column 211 and the second transverse support column 212.

[0071] In this embodiment, optionally, part of the second transverse support columns 212 of the first split frame 210 can abut against the side of the corbel 012 away from the first support frame 100 to improve the stability of the first split frame 210 .

[0072] In addition, the first split frame 210 and the second split frame 220 can be detachably connected by a steel member.
