[0007] As preferred, the overhanging platform is provided with guardrail.

[0008] Compared with prior art, the utility model has the advantages and positive effects that:

[0009] The utility model uses prefabricated overhanging platform, and preset support beam and pull rod before pier pouring, and the support beam and pull rod are stably fixed after pier pouring, so that the overhanging platform is fixed by the support beam and pull rod conveniently, and the utility model is arranged below pier, not limited by road width. BRIEF DESCRIPTION OF DRAWINGS

[0010] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] Figure 1 This is a schematic diagram of a structure that combines an elevated bridge and a suspended monorail bridge.

[0012] Figure 2 This is a view of the suspended platform from above.

[0013] In the above figures, 1 is the bridge pier; 11 is the supporting beam; 12 is the tie rod; 2 is the box girder; 3 is the track beam; 4 is the monorail; 5 is the suspended platform; 51 is the mounting slot; 52 is the connector; 6 is the inclined ladder; and 7 is the stay cable. Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] like Figure 1 , Figure 2 As shown, a structure combining an elevated bridge and a suspended monorail bridge includes a pier 1, a box girder 2 above the pier 1, and a track beam 3 suspended below the box girder 2. The track beam 3 is used to run a monorail vehicle 4. The above is prior art and will not be described in detail here. To facilitate the construction of the suspended platform, this utility model also includes a prefabricated steel structure suspended platform 5. Since the pier 1 is a reinforced concrete structure, several outwardly extending support beams 11 are pre-installed on the pier 1 before the concrete is poured. After the concrete is poured, the support beams 11 are firmly fixed. Several installation slots 51 are provided on the lower side of the suspended platform 5 corresponding to the support beams 11. The support beams 11 are inserted into the installation slots 51. Positioning bolts for positioning the suspended platform 5 are provided on the side of the installation slots 51. The positioning bolts connect the installation slots 51 to the support beams to facilitate the installation of the suspended platform 5. A connector 52 is provided at the end of the suspended platform 5 away from the pier 1. The connector 52 is connected to a stay cable 7. A tie rod 12 is connected to the upper end of the stay cable 7. One end of the tie rod 12 is inserted into the pier 1. That is, the tie rod 12 and the support beams 11 are also fixed after the concrete is poured.

[0017] Specifically, the high bridge in the middle of the wide road, the distance from the roadside to the high bridge is long, and the difficulty of constructing the suspended platform 5 is large, therefore, the utility model constructs the suspended platform 5 under the high bridge, and utilizes the pier 1 as the support, reduces the additional construction, the support beam 11 provides the support for the suspended platform 5, and the inhaul cable 7 provides the pulling force for the end of the suspended platform 5 far from the pier 1, so that the utility model realizes fixing the suspended platform 5 on the high bridge.

[0018] Further, the suspended platform 5 is connected with the inclined ladder 6, and the lower end of the inclined ladder 6 is placed on the ground.

[0019] Further, the suspended platform 5 is in T shape from the perspective of looking down.

[0020] Further, the suspended platform 5 is provided with the guardrail.

[0021] The above is only the preferred embodiment of the utility model, and is not other forms of the limitation of the utility model, any skilled person in the art can utilize the disclosed technical content to make changes or modifications into the equivalent embodiment applied to other fields, but any simple modification, equivalent change and modification made according to the technical essence of the utility model to the above embodiment without departing from the technical scheme content of the utility model still belongs to the protection scope of the technical scheme of the utility model.
