A MOBILE AND CYCLIC BEAM-DROPPING BRACKET FOR A CONTINUOUS BEAM
O# BLOCK
This invention belongs to the technical field of continuous beams, particularly relating to a mobile and cyclic beam-dropping bracket for a continuous beam 0# block.
With the development of the economy and the increasing demands for urban landscapes, the use of various continuous beams in bridge engineering to span different routes has become increasingly common. The construction of the continuous beam O# block, as the first step in the construction of the bridge superstructure, involves heavy construction weight, high working height, and high safety risks. It is a key procedure in the construction of continuous beams, and ensuring the safety of its construction work is of utmost importance. At present, the construction of the continuous beam 0# block mainly adopts ground support brackets and pier top brackets. Due to their prefabrication in the factory, easy installation, and good adaptability to the site environment and pier height, pier top brackets are increasingly used in the construction of continuous beam O# blocks, enhancing the efficiency of bracket installation and removal, and improving material turnover efficiency, which is of great significance for saving construction costs of continuous beams.
In existing technology, patent publication number CN214401417U discloses a rotatable bracket for a continuous beam 0# block, where the various rods are connected by hinges, and the rods are separated by the removal of the hinges. Patent publication number
CN117090139A discloses a bracket device that uses pier body embedded parts and bolt connections to the pier body, and uses a sand box to implement the bracket dismantling and formwork removal.
In the aforementioned bracket devices, the production and installation of hinged rods, the positioning of embedded parts, and other processes have high technical requirements and present some difficulties in actual on-site operations.
2 LU507663
To solve the aforementioned problems existing in current technology, the purpose of this invention is to provide a mobile and cyclic beam-dropping bracket for a continuous beam O# block that is easy to assemble and disassemble.
The technical solution adopted by this invention is:
À mobile and cyclic beam-dropping bracket for a continuous beam 0# block, including a corbel embedded in the pier column of the bridge pier, with a wedge drop beam device connected to the corbel; it also includes a shaped steel frame, the lower end of the shaped steel frame is connected to the wedge drop beam device, and the upper end of the shaped steel frame is connected to the pier cap.
The wedge drop beam device of this invention relies on the wedging action of the inclined surfaces to press the shaped steel frame tightly, ensuring the stability of the shaped steel frame after installation. The inclined surfaces of the wedge drop beam device are not connected, and during disassembly, separating the inclined surfaces of the wedge drop beam device allows for the rapid disassembly of the shaped steel frame. This invention facilitates the lowering of the wedge drop beam device, the removal of the formwork and shaped steel frame, and achieves rapid disassembly and turnover of the bracket.
As a preferred embodiment of this invention, the wedge drop beam device includes an adjusting threaded rod and four wedge steel ingots, arranged in a return pattern. The upper wedge steel ingots are connected to the shaped steel frame, the lower wedge steel ingots are connected to the corbel, and the adjusting threaded rod passes through the left and right wedge steel ingots, with adjusting nuts threaded on both ends of the adjusting threaded rod.
During installation, tightening the adjusting nuts pushes the left and right wedge steel ingots inward. Under the squeezing action, the left and right wedge steel ingots move diagonally upward relative to the lower wedge steel ingots, and the upper wedge steel ingots move diagonally upward relative to the left and right wedge steel ingots, thus moving the upper wedge steel ingots upward in a straight line. After the upper wedge steel ingots have moved into place, it is convenient to accurately connect the upper end of the shaped steel frame to the bridge segment cap. During disassembly, the adjusting nuts are turned in the opposite direction, moving the left and right wedge steel ingots apart until the upper wedge steel ingots
3 LU507663 separate from the left and right wedge steel ingots, at which point it is convenient to disassemble the shaped steel frame.
As a preferred embodiment of this invention, the inner sides of the wedge steel ingots are chamfered. A space is left on the inner side of the four wedge steel ingots to facilitate their inward movement.
As a preferred embodiment of this invention, the inner planes of the left and right wedge steel ingots are parallel to each other. When the left and right wedge steel ingots move towards each other, their inner planes fit together, improving the stability of the wedge drop beam device.
As a preferred embodiment of this invention, for solid piers, corbels are set on both sides of the pier column.
As a preferred embodiment of this invention, it also includes tie rods, which are connected to the corbels on both sides of the pier column, with tie nuts threaded on the ends of the tie rods.
After tightening the tie nuts, the tie rods pull and fix the corbels on both sides.
As a preferred embodiment of this invention, for hollow piers, the ends of the corbels protrude from both sides of the pier column. The full length of the corbel passes through the whole pier column, allowing the corbel to also serve as a platform for setting up the formwork support bracket for the upper solid section.
As a preferred embodiment of this invention, the pier cap is pre-embedded with fastening threaded rods, the shaped steel frame is fixed with end caps, and the fastening threaded rods pass through the end caps and are locked by fastening nuts. Tightening the fastening nuts fixes the end cap of the shaped steel frame to the pier cap.
As a preferred embodiment of this invention, both sides of the end cap are connected with a fastening threaded rod.
As a preferred embodiment of this invention, the shaped steel frame includes a tripod, the upper end of the tripod is connected to the pier cap, the lower end of the tripod is connected to the wedge drop beam device, and several cross bars connect the tripods on the same side.
The beneficial effects of this invention are:

The wedge drop beam device 4 of this invention relies on the wedging action of the inclined surfaces to press the shaped steel frame 5 tightly, ensuring the stability of the shaped steel frame 5 after installation. The inclined surfaces of the wedge drop beam device 4 are not connected, and during disassembly, separating the inclined surfaces of the wedge drop beam device allows for the rapid disassembly of the shaped steel frame 5. This invention facilitates the lowering of the wedge drop beam device 4, the removal of the formwork and shaped steel frame 5, and achieves rapid disassembly and turnover of the bracket.
Specifically, the wedge drop beam device 4 includes an adjusting threaded rod 41 and four wedge steel ingots 42, arranged in a return pattern. The upper wedge steel ingots 42 are connected to the shaped steel frame 5, the lower wedge steel ingots 42 are connected to the corbel 3, and the left and right wedge steel ingots 42 have pre-drilled holes, with the adjusting rod passing through the holes of the left and right wedge steel ingots 42, and both ends of the adjusting threaded rod 41 are threaded with adjusting nuts 43. For round-end piers, a seam steel plate is used to fill the gap between the wedge drop beam device 4 and the pier body 1.
During installation, tightening the adjusting nuts 43 pushes the left and right wedge steel ingots 42 inward. Under the squeezing action, the left and right wedge steel ingots 42 move diagonally upward relative to the lower wedge steel ingots 42, and the upper wedge steel ingots 42 move diagonally upward relative to the left and right wedge steel ingots 42, thus moving the upper wedge steel ingots 42 upward in a straight line. After the upper wedge steel ingots 42 have moved into place, it is convenient to accurately connect the upper end of the shaped steel frame 5 to the bridge segment cap 2. During disassembly, the adjusting nuts 43 are turned in the opposite direction, moving the left and right wedge steel ingots 42 apart until the upper wedge steel ingots 42 separate from the left and right wedge steel ingots 42, at which point it is convenient to disassemble the shaped steel frame 5.
