[0002] Due to the good mechanical properties and the convenience of processing and installation of steel structures, more and more steel bridges are being used in urban bridge construction. At the same time, considering the aesthetics of the bridge body, decorations can be made on the bottom and side of the steel bridge. For long-span steel bridges, their cross-section height is relatively large. If the width of the bridge body is relatively wide, reaching 20 - 30m, or the internal functional structure is complex, the construction of the bottom of the bridge body and the interior of the bridge will become difficult. Due to its span, the bridge maintenance vehicle cannot meet the tasks of bridge bottom construction or maintenance. For bridge bodies with a relatively high cross-section, the hanging basket-type maintenance hanger also cannot meet the construction requirements. Especially for the vertical rotation type opening bridge with a large cross-section beam and slab structure, the internal decoration and maintenance height of the bridge body is high, and the internal structure is complex, and the ordinary beam bottom maintenance platform cannot meet the requirements.

[0047] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be interactively combined without mutual contradiction and conflict.

[0048] For the vertical rotating opening bridge with large cross-section beam and slab structure, the internal decoration and maintenance height of the bridge body 1 is high, and the internal structure is complex, so the traditional maintenance platform at the bottom of the beam cannot meet the requirements. A suspended construction platform of the present utility model can be provided with a scaffolding 215, and the operation platform of the scaffolding 215 can be set up according to different internal structures. It can be used for internal construction of the bridge body 1 and also for construction at the bottom of the bridge body 1.

[0049] Refer to Figure 1-8, A suspended construction platform, comprising: at least two trusses 2 arranged side by side and passing through the bottom of the bridge. Adjacent trusses 2 are fixedly connected by a first connecting member 201 to form a continuous construction platform; both ends of the truss 2 are provided with first lifting lugs 204, and a plurality of second lifting lugs 205 are provided between both ends of the truss 2; the first lifting lugs 204 are connected to the bridge body 1 through a second connecting member 202, and the second lifting lugs 205 are connected to the bridge body 1 through a third connecting member 203 to enhance the bearing capacity of the truss 2; third lifting lugs 218 are further provided at both ends of the truss, and the third lifting lugs 218 are connected through a fourth connecting member 217, and the truss 2 is hoisted in place through the fourth connecting member 217. The truss 2 has high bearing capacity, high stability, durability, earthquake resistance, etc., making it an indispensable and important part in modern architecture and engineering. The utility model utilizes at least two trusses 2 arranged side by side and connects them through a first connecting member 201 between adjacent trusses 2 to achieve the purpose of expanding the construction area of the construction platform. Among them, the first lifting lugs 204 are connected to the bridge body 1 through the second connecting member 202, so that the construction platform composed of the trusses 2 is suspended at the bottom of the bridge body 1. To further enhance the bearing capacity of the bridge body 1, a number of second lifting lugs 205 are provided to connect with the bridge body 1. It should be noted that the first lifting lugs 204 are load-bearing lifting lugs, installed at both ends of the truss 2 for bearing the truss 2; the second lifting lugs 205 are working lifting lugs, and a plurality of them are arranged along the extension direction of the truss 2. According to the actual working conditions, the working lifting lugs can be connected to the bridge body 1 through the third connecting member 203 to enhance the bearing capacity of the operating platform. In addition, the working lifting lugs are also used to support and suspend construction workers or equipment for operations at high altitudes or specific positions; the third lifting lugs 218 are installation lifting lugs, used for connecting the installation lifting lugs through the fourth connecting member 217 during installation to hoist the truss in place.

[0050] Specifically, the first connecting member 201 includes a steel pipe and fastening bolts, and the steel pipe is fixed between adjacent trusses 2 through the fastening bolts. Specifically, the steel pipe is preferably a scaffolding 215 steel pipe.

[0051] Specifically, the second connecting member 202 and the third connecting member 203 can be rope bodies, preferably steel ropes.

[0052] In some embodiments, the first lifting lugs 2 and the third lifting lugs 218 can be lifting lugs with the same structure. As long as they can achieve the functions of installation and bearing.

[0053] In some embodiments, refer to Figure 3-5, 7 - 8, the truss 2 includes an upper chord 2061, a lower chord 2071, web members 208, and diagonal braces 209; there are at least two upper chords 2061, which are fixedly connected by a first cross - link 2062 to form an upper chord surface 206; there are at least two lower chords 2071, which are fixedly connected by a second cross - link 2072 to form a lower chord surface 207; the upper chord surface 206 and the lower chord surface 207 are arranged in parallel, and the web members 208 are vertically connected between the upper chord 2061 and the lower chord 2071 at relative positions; the diagonal braces 209 are obliquely arranged between the upper chords 2061 and the lower chords 2071 at different positions. It can be understood that the truss 2 is mainly strengthened as a whole by the diagonal braces 209 arranged between the upper chords 2061 and the lower chords 2071 at different positions. That is to say, the diagonal braces 209 are cross - arranged inside the truss 2, forming several triangular structures inside the truss 2. Due to the stable structure of the triangle, the truss 2 has extremely strong load - bearing capacity. Among them, the chord members, the lower chord 2071, the web members 208, the first cross - link 2062, the second cross - link 2072, and the diagonal braces 209 are all made of steel structures and are fixed by bolting or welding.

[0054] Further, referring to Figure 5 , a gangplank 210 is laid on both the upper chord surface 206 and the lower chord surface 207; after the gangplank 210 is laid on the upper chord surface 206, a construction platform is formed; after the gangplank 210 is laid on the lower chord surface 207, a storage platform 211 is formed for storing construction materials. After laying the gangplank 210, a construction platform is formed above the truss 2. Preferably, a gangplank 210 is also laid between adjacent trusses 2 and above the first connector 201, so that an integral construction platform is formed between the two trusses 2 to meet the maintenance work of large - section bridges. In addition, a storage platform 211 is formed below the construction platform, that is, on the lower chord surface 207, which can be used to store some light construction materials, reduce the frequency of material handling back and forth, and improve construction efficiency. A manhole 212 is provided on the construction platform for accessing the storage platform 211. Workers can freely shuttle between the construction platform and the storage platform 211 through the manhole 212 to pick up construction materials. Specifically, the manhole 212 can be a through - hole provided on the gangplank 210 or a passage formed by removing the gangplank 210 to form the manhole 212.

[0055] In some embodiments, referring to Figure 3 , 7 , since it is high - altitude operation and the construction working conditions are relatively dangerous, to improve the safety during construction, guardrails 216 are provided on both sides along the extending direction of the truss 2 above the construction platform. That is to say, the guardrails 216 enclose the entire construction platform, protecting the safety of workers when they are working on the construction platform.

[0056] In some embodiments, with reference to Figure 2 and 6 , on the construction platform, the scaffolding 215 will be flexibly erected according to the specific internal structure of the bridge body 1 to make up for the height difference between the construction platform and the construction site. The operation platform may shake during use, which poses a certain safety hazard to the erected scaffolding 215. Therefore, a plurality of positioning structures 213 are provided on the construction platform, and the scaffolding 215 is erected on the construction platform. The scaffolding 215 is positioned through the positioning structures 213. The scaffolding 215 is positioned and fixed through the positioning structures 213. In this way, even if the construction platform shakes during use, the scaffolding 215 will be firmly fixed on the platform, eliminating the risk of tipping over.

[0057] To further improve the safety of the scaffolding 215, with reference to Figure 2 , a fastening member 214 connected to the bridge body 1 is provided on the scaffolding 215 to provide support for the scaffolding 215. Since the structures of the bridge bodies 1 are different, when erecting the scaffolding 215 under specific working conditions, the connection positions can be determined according to the height of the scaffolding 215 and the distance between the scaffolding 215 and the bridge body 1. Among them, one end of the fastening member 214 can be bolted to the scaffolding 215, and the other end can be buckled or bolted to the bridge body 1.

[0058] Furthermore, on the scaffolding 215, with reference to Figure 2 , a guardrail is arranged along the operation area on the scaffolding 215 to protect the safety when working on the scaffolding 215.

[0059] In some embodiments, with reference to Figure 1 , the second connecting member 202 is fixedly connected to the bridge body 1 through an anchor member 11 provided on the bridge body 1; a chain hoist device 12 is arranged between the second connecting member 202 and the anchor member 11 for adjusting the length of the second connecting member 202. Since the operation platform of the present invention is large and heavy, therefore, a place with high enough strength on the bridge body 1 is selected as the anchor member 11, and the entire weight of the operation platform can be better borne through the anchor member 11 provided on the bridge body 1. In addition, to further improve the usability of the operation platform, the length of the second connecting member 202, that is, the steel wire rope, can be adjusted through the chain hoist device 12, so that the operation platform can be raised or lowered relative to the bridge body 1.

[0060] Further, a pulley assembly is arranged on the bridge body 1 on the side of the chain hoist device 12 away from the anchor member 11. Through the pulley assembly 13, the chain hoist device 12 can adjust the length of the steel wire rope more labor-saving. Specifically, the chain hoist device 12 is an electric chain hoist device 12, which is more labor-saving and safe.

[0061] The above is a specific description of the preferred embodiment of the present utility model. However, the present utility model is not limited to the described embodiment. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present utility model. These equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
