Description

Technical Field

[0001] The present application relates to the field of high pier column construction, and in particular to a lifting frame for the formwork climbing construction of high pier columns. Background Technique

[0002] At present, the formwork climbing construction technology for high pier columns is a commonly used construction method in bridge engineering, especially suitable for high pier operations above 25 meters, including high piers with various cross-sectional forms such as circular, conical, and rectangular. This technology can effectively improve the construction quality of highway bridge projects and the safety guarantee level during the construction process.

[0003] Currently, a lifting frame is used for the formwork climbing construction of high pier columns. The working platform is supported on the corbel brackets or vertical and horizontal rib straps of the steel formwork, and the working platform and formwork are lifted by a tower crane. Construction workers perform operations such as formwork installation, removal, steel bar tying, pouring, tamping, and measurement on the upper and lower layers of the working platform.

[0004] The above-mentioned existing technical solutions have the following defects: When the construction workers build the lifting frame, the lifting frame is fixed on the high pier column, and the construction workers need to manually screw the fixing steel plate into the high pier column to fix the lifting frame. The steel rod is located at the lower layer of the lifting frame. During installation, the construction workers need to hang in the air, which poses a risk of falling and has low safety. Utility Model Content

[0005] In order to quickly and automatically fix the lifting frame at the formwork climbing construction position of the high pier column and reduce the possibility of danger when fixing the lifting frame, the present application provides a lifting frame for the formwork climbing construction of high pier columns.

[0006] The above technical object of the present application is achieved through the following technical solutions:

[0007] A lifting frame for the formwork climbing construction of high pier columns includes an installation platform and a telescopic installation component. The installation platform is sleeved on the high pier column, and the telescopic installation component is arranged at the lower part of the installation platform. The telescopic installation component includes an installation part, a driving sleeve, and a fixing column. The installation part is arranged at the lower part of the installation platform, and placing cavities are opened on the opposite surfaces of the installation part. The driving sleeve is rotatably arranged in the placing cavity, and the fixing column is slidably arranged in the driving sleeve.

[0008] By adopting the above technical solutions, by setting the installation platform and the telescopic installation component, the lifting frame can be quickly fixed at the position for formwork climbing construction of the high pier column, avoiding the situation that construction workers fix the lifting frame in a suspended state and improving safety. The telescopic installation component includes an installation part, a driving sleeve, and a fixing column. Rotate the driving sleeve, and drive the fixing column to move towards the direction close to the pier column body until it is inserted into the fixing hole reserved on the pier column body, thereby fixing the height of the lifting frame. Compared with the installation and fixation by construction workers, the work efficiency is improved.

[0009] Optionally, a threaded driving groove is provided on the driving sleeve, a driving member is fixedly arranged on the peripheral wall of the fixed column, the driving member can slide along the driving groove, the telescopic mounting assembly further includes a motor, the motor is arranged at the lower part of the mounting table, and the end of the motor output shaft is coaxially and fixedly connected to the end of the driving sleeve.

[0010] By adopting the above technical solution, since the driving member can slide along the driving groove, when the driving sleeve is rotated by the motor, the side wall of the driving groove and the peripheral wall of the driving member slide relative to each other. Because the driving groove is threaded, the fixed column can be moved towards the main body of the pier until it is inserted into the fixing hole reserved on the pier body, so as to fix the height of the climbing formwork, which is convenient for the subsequent climbing formwork construction of high piers.

[0011] Optionally, a limiting groove is provided on the peripheral wall of the placement cavity, and the end of the driving member is slidably arranged in the limiting groove.

[0012] By adopting the above technical solution, by providing the limiting groove, the rotation of the fixed column during movement can be avoided, and the work efficiency can be reduced.

[0013] Optionally, the mounting table includes a mounting frame and a mounting plate. The mounting plate is laid on the upper part of the mounting frame. The climbing formwork further includes a lifting member. The mounting plate is provided with a receiving hole. The lifting member is arranged in the receiving hole. One end of the lifting member is hinged to the mounting frame, and the other end of the lifting member is provided with a lifting hole.

[0014] By adopting the above technical solution, by providing the lifting member with a lifting hole, after the climbing formwork construction of the first-level high pier is completed, the climbing formwork is lifted by using a tower crane hook to hook the lifting member, which is convenient for the subsequent climbing formwork construction of high piers. The receiving hole can accommodate the lifting member and prevent the lifting member from being damaged.

[0015] Optionally, a blocking groove is provided at the upper end of the hole wall of the receiving hole. The climbing formwork further includes a cover plate, and the cover plate is hinged to the groove wall of the blocking groove.

[0016] By adopting the above technical solution, by providing the cover plate, the lifting member can be protected to prevent the lifting member from being damaged during the climbing formwork construction of high piers.

[0017] Optionally, the side wall of the cover plate hinged to the blocking groove is processed to form a protruding arc surface.

[0018] By adopting the above technical solution, the protruding arc surface formed on the cover plate can make the cover plate rotate more easily and improve the work efficiency.

[0019] Optionally, the climbing frame further includes vertical columns and horizontal columns. The vertical columns are vertically arranged on the upper surface of the mounting plate, and the horizontal columns are arranged at the upper ends of the vertical columns. Multiple horizontal columns are perpendicularly welded to form a platform frame.

[0020] By adopting the above technical solution, by arranging the vertical columns and horizontal columns, support can be provided for the staff to carry out the form turnover construction of high pier columns. The platform frame composed of horizontal columns is provided with multiple layers, which can improve the form turnover construction efficiency of high pier columns.

[0021] Optionally, diagonal columns are fixedly connected between the horizontal columns.

[0022] By adopting the above technical solution, by arranging the diagonal columns, the support strength of the horizontal column platform can be enhanced, and the safety of the staff during construction on the climbing frame can be improved.

[0023] In summary, the present application has the following technical effects:

[0024] 1. By arranging the installation platform and the telescopic installation component, the climbing frame can be quickly fixed at the position for form turnover construction of high pier columns, avoiding the staff from fixing the climbing frame in a suspended state and improving safety.
