[0027] The embodiment of the present application provides a pier body construction platform, which can solve the problems of difficulty in controlling the overall stability of the pier body construction platform, many safety hazards and great safety risks.

[0028] This embodiment is described in the state that a pier body construction platform disclosed in this application has been built. Figure 1 Structural diagram of the pier construction platform installed on the bridge cap and Figure 2The top view of the pier body construction platform installed on the bridge pedestal includes multiple support bases 1, multiple support base embedded parts 1 corresponding to the number of support bases 1 and used to be buried in the bridge pedestal 5, one or more circular frames 2 and multiple connecting parts.

[0029] In this embodiment, four supporting bases 1 are specifically provided, four supporting base embedded parts 1 are also provided, and two circular frames 2 are provided. The supporting base embedded parts 1 are embedded in advance at the four corners of the bridge pier 5, and a supporting base 1 is fixed on each supporting base embedded part 1. A connecting piece is provided on each of the four supporting bases 1. The four supporting bases 1 are connected to the four corners of the circular frame 2 through the connecting piece. After the circular frame 2 connected to the supporting base 1 is fixed, a second circular frame 2 is erected along the vertical direction of the bridge pier body. The four circular frames 2 are also connected to the four corners through four connecting pieces to complete the connection and fixation. Since the supporting base embedded parts 1 are embedded in the bridge pier 5 in advance, so that the supporting base 1 is more stable on the bridge pier 5, and the circular frame 2 is connected to the supporting base 1 through the connecting piece, the overall structure is more integrated, thereby improving the overall stability of the pier body construction platform.

[0030] Reference Figure 3 The overall structural diagram of the embedded parts of the support base, the embedded parts 1 of the support base include an embedded steel plate 111, a plurality of embedded bolts 112 and a plurality of embedded steel bars 113. In the present embodiment, three embedded steel bars 113 are welded on the embedded steel plate 111 and four embedded bolts 112 are fixed thereto. Four bolt holes are provided on the support base 1 corresponding to the embedded bolts 112 so that the support base 1 can be fixed more stably on the embedded steel plate 111. When installing the pier body construction platform, the embedded steel bars 113 are inserted into the interior of the bridge pedestal 5 so that the embedded steel plate 111 is fixed on the surface of the bridge pedestal 5. Then the embedded bolts 112 are passed through the bolt holes on the support base 1. The embedded bolts 112 are tightened to complete the embedding work of the embedded parts 1 of the support base and the connection and fixation between the support base 1 and the embedded parts 1 of the support base. The structure is simple and the installation is convenient.

[0031] In order to further strengthen the load-bearing capacity of the support base 1, four reinforcing steel plates 12 are welded to the support base 1, so that the support base 1 can more stably support the circular frame 2 and improve the stability of the pier body construction platform.

[0032] Reference Figure 4 A top view of the support base and the connecting member. In the present embodiment, the connecting member is specifically configured as a connecting angle steel 3 and a connecting bolt. The connecting angle steel 3 is provided with a plurality of connecting holes for passing the connecting bolts, and the connecting angle steel 3 is welded and fixed to the upper end of the support to complete a rigid connection between the connecting angle steel 3 and the support, so that the connection between the connecting angle steel 3 and the support is more stable.

[0033] Reference Figure 1 Structural diagram of the pier construction platform installed on the bridge cap and Figure 2 A top view of the pier construction platform installed on the bridge cap. The circular frame 2 includes a protective net frame 21 and a skeleton structure. In this embodiment, the skeleton structure is composed of a plurality of vertical poles 22 and a plurality of horizontal cross bars 23. The vertical poles 22 and the horizontal cross bars 23 are also connected to each other through connecting angle steels 3 and connecting bolts. Both ends of the vertical poles 22 and the horizontal cross bars 23 are provided with connecting holes adapted to the connecting bolts, so that the vertical poles 22 and the horizontal cross bars 23 are connected and fixed by connecting bolts. The connection method is simple, and the connecting angle steels 3 are connected. It can improve the stability of the connection between the vertical poles 22 and the horizontal crossbars 23, making the skeleton structure more stable; the protective net frame 21 includes a steel mesh 211 and a steel frame 212. The steel mesh 211 is laid on the bottom plane of the skeleton structure and on the plane parallel to the skeleton structure and the bridge pier body. The steel frame 212 is welded obliquely on the steel mesh 211 to further improve the strength of the steel mesh 211, thereby improving the bearing capacity of the pier body construction platform to ensure the personal safety of construction workers when performing construction operations on the pier body construction platform.

[0034] During the construction of high piers, since their span, load and height are greater than those of ordinary road bridges, for some high-height bridge piers, construction workers usually first construct at the bottom of the bridge pier, and then connect the second layer of the circular frame 2 to gradually raise the bridge pier in layers. In order to further improve the stability of the multi-layer pier construction platform, a balancing rod 4 is also provided in this example. One end of the balancing rod 4 is buried inside the bridge pier, and the other end of the balancing rod 4 extends from the bridge pier and is connected to the skeleton structure. Figure 2 In this embodiment, four balancing rods 4 are specifically provided, and the balancing rods 4 extend from the bridge pier body and are welded and fixed to the horizontal cross bar 23 in the upper part of the lower circular frame 2, so that the pier body construction platform with multi-layer circular frames 2 can be more stable and reduce the existence of safety hazards.

[0035] In order to facilitate the construction workers to carry out high pier construction, refer to Figure 1Structural schematic diagram of the pier body construction platform installed on the bridge pier, a ladder passage 24 is also set up between adjacent circular frames 2, and the protective net frame 21 on the bottom plane of the circular frame 2 has a hollow portion reserved at the corners of the protective net frame 2 to facilitate the installation of the ladder passage 24. In this embodiment, the ladder passage 24 is fixedly connected to the protective net frame 21 with iron wire. In other embodiments, the ladder passage and the protective net frame 21 can also be fixed with connecting bolts, so that the ladder passage 24 can be more firmly installed between adjacent circular frames 2, thereby facilitating construction personnel to move freely between the circular frames 2 on different floors, thereby avoiding the need to provide additional facilities such as climbing frames and lifting platforms for the pier body construction platform during the construction of high piers with higher heights, so as to improve the construction efficiency of high pier construction.

[0036] The implementation principle of the present application is: when setting up the pier body construction platform, the embedded steel bars 113 are first embedded in the bridge pedestal 5, so that the embedded steel plate 111 is fixed on the surface of the bridge pedestal 5, and then the embedded bolts 112 are passed through the bolt holes on the support base 1, and the connecting angle steels 3 are welded to the upper end of the support base 1 after tightening the embedded bolts 112, and then the connecting bolts and the connecting angle steels 3 are used to splice multiple columns and multiple horizontal cross bars 23 to form a skeleton structure, and a steel mesh 211 with a steel skeleton 212 welded obliquely is laid on the bottom plane of the skeleton structure and the plane parallel to the bridge pier body; for a bridge pier body with a higher height, the splicing of the multi-layer circular frames 2 is also completed by connecting the angle steels 3 and the connecting bolts, and the balancing pull rods 4 are embedded in the bridge pier body, and the extended ends of the balancing pull rods 4 are welded and fixed to the upper horizontal cross bars 23 in the lower circular frame 2, and finally a ladder channel 24 is set up between adjacent circular frames 2, so that the installation of the pier body construction platform can be completed.
