Abstract

The invention provides an operating platform for high bridge pier steel bars. The two ends of a vertical force-bearing support are connected with an upper horizontal force-bearing support and a lower horizontal force-bearing support respectively, an inclined force-bearing support is arranged between the vertical force-bearing support and the upper horizontal force-bearing support, and the vertical force-bearing support, the upper horizontal force-bearing support, the lower horizontal force-bearing support and the inclined force-bearing support form a stable steel structure. A protective fence is arranged on the upper horizontal force-bearing support, a safety protective net is installed on the protective fence, platform scaffold boards are laid on the upper horizontal force-bearing support and the lower horizontal force-bearing support respectively, and the lower horizontal force-bearing support is connected with a supporting frame through a bolt. An upper operating platform body and a lower operating platform body can be provided, the safety of high bridge pier steel bar operation is well guaranteed, and the sense of safety of operating personnel is greatly improved; the operating speed of installing the steel bars is greatly increased, and the high bridge pier operating personnel can perform operation conveniently, rapidly, safely and reliably.

Example Embodiment

[0011] The structure of the present invention is as figure 1 As shown in -2, a steel bar working platform for high piers of a bridge, the two ends of the vertical force-bearing support 8 are respectively connected with the upper horizontal force-bearing support 7 and the lower horizontal force-bearing support 7', and the vertical force-bearing support 8 is connected with the upper horizontal force-bearing support. There is also an oblique force bearing bracket 9 between the 7, the vertical force bearing bracket, the upper and lower horizontal force bearing brackets and the oblique force bearing bracket constitute a stable and stable steel structure 1, and the upper horizontal force bearing bracket 7 is provided with Guardrail 2, a safety net 4 is installed on the guardrail 2, platform scaffolding boards 3 are paved on the upper horizontal force bearing bracket 7 and the lower horizontal force bearing bracket 7', and the lower horizontal force bearing bracket 7' passes through the bolt 6 Connect to the support frame 5. The components constituting the steel structure 1 are connected by bolts or welding. The side of the support frame 5 is provided with support frame bolts 10 for fixing the support frame 5 on the template 11 .
[0012] The manufacturing process of the present invention is as follows:
[0013] (1) Cut the material according to the design drawings, and use angle steel or channel steel to make vertical force-bearing brackets 8, upper horizontal force-bearing brackets 7, lower horizontal force-bearing brackets 7' and oblique force-bearing brackets 9;
[0014] (2) At the position where the steel structure 1 of the upper and lower platforms is released on the production platform, it should be noted that the minimum size of the upper platform ring inward is larger than the outer size of the high pier formwork 11 (it can be controlled by 15~20cm), and it should be welded or connected by bolts. , removed from the production platform for backup;
[0015] (3) Use a crane to lift and align the upper platform. After the position of the upper platform meets the requirements, it is welded with the vertical vertical, horizontal and horizontal inclined brackets, and the working platform is completed by a stable steel structure 1 composed of horizontal, vertical and oblique force-bearing brackets;
[0016] (4) Welding and installing the guardrail 2 of the two platforms, laying the platform foot plate 3, and installing the guard net 4;
[0017] (5) Weld or bolt the support frame 5 on the installation formwork on the outside of the high pier formwork 11, and the structure of the steel bar working platform for the high pier of the bridge is completed.
[0018] After the installation of the present invention is completed, a stable steel structure composed of horizontal, vertical and oblique supporting force-bearing profiles (angle steel, channel steel, etc.) in a circumferential direction is formed around the high pier, and two upper and lower working platforms are formed. There is a certain height difference between the platforms. The steel bar binding operators of the high piers of the bridge can complete the construction work on the two platforms. The operators on the upper and lower working platforms can cooperate with each other to install the steel bars quickly and conveniently. The two platforms can be scattered and reasonably stacked. .
