Description

Technical Field

[0001] The utility model belongs to the technical field of high pier construction of bridges, and in particular relates to a hydraulic climbing formwork and a construction elevator connecting platform for high pier bridge construction. Background Art

[0002] For high bridge piers with a height of ≥40m, hydraulic climbing formwork and construction elevators are currently commonly used to ensure construction quality and safety for construction workers to go up and down the high bridge piers. However, the installation of construction elevators has strict regulations on the angle and length of attachment, and the hydraulic climbing formwork has its own operating platform, and its width setting is mainly based on the length requirement of the backward sliding track during the demoulding process. The higher the bridge pier is and the larger the cross-sectional size of the pier body is, the wider the required operating platform width is. Therefore, the above method has the following defects in the actual construction process: there is a cross-conflict between the position of the construction elevator cage and the operating platform of the hydraulic climbing formwork in the plane position, and the construction personnel cannot reach the bottom operating platform of the hydraulic climbing formwork through the construction elevator. In actual construction, the conventional way to solve this problem is to set a corresponding limit device for the construction elevator so that the top reaches a certain distance from the bottom of the hydraulic climbing formwork operating platform and stops. The construction personnel go up and down the high piers of the bridge by the simple steel ladder welded in advance on the hydraulic climbing formwork frame. However, this approach has great safety risks. The higher the pier is, the greater the risk is. In addition, the simple steel ladder needs to be welded on the hydraulic climbing formwork frame in advance, which is difficult to weld and install, has a long disassembly cycle, and has low work efficiency. It cannot be circulated after the construction is completed, resulting in waste. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provide a hydraulic climbing formwork and a construction elevator connecting platform for high pier bridge construction, thereby solving the cross-conflict between the construction elevator cage and the operating platform of the hydraulic climbing formwork in the plane position. Construction personnel can quickly and safely reach the high pier bridge for construction, thereby reducing operation risks and improving work efficiency.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A hydraulic climbing formwork and a construction elevator connecting platform are used for high pier bridge construction. The connecting platform includes a platform bottom surface, a rectangular frame surrounded by a plurality of horizontal bars and a plurality of vertical bars, a movable door arranged on one side of the rectangular frame, an electrical interlocking device installed on the movable door, and a ladder arranged in the rectangular frame; the bottom edge of the rectangular frame is fixedly connected to the bottom surface of the platform, a connecting hole is provided on the top edge of the rectangular frame, and the top of the rectangular frame is connected to the hydraulic climbing formwork frame through the connecting hole and high-strength bolts, and the electrical interlocking device controls the construction elevator to automatically cut off power and stop running when the movable door is opened.

[0006] Furthermore, a dense safety net is arranged on the side of the rectangular frame.

[0007] Furthermore, skirting boards are arranged around the connection between the rectangular frame and the bottom of the platform.

[0008] Furthermore, the bottom surface of the platform is a 5mm closed patterned steel plate, and the plurality of cross bars and the plurality of vertical bars are galvanized steel pipes.

[0009] Beneficial effects of the utility model:

[0010] The utility model discloses to connect the hydraulic climbing formwork frame with the construction elevator, avoids welding the steel ladder on the hydraulic climbing formwork frame in advance, only needs to fix the connection platform, and the installation is convenient and fast; it solves the intersection conflict in the plane position between the existing construction elevator cage and the operating platform of the hydraulic climbing formwork, ensures that the construction personnel can reach the high pier bridge safely and quickly for construction, reduces the construction risk and improves the work efficiency.
