Description

Technical Field

[0001] This invention belongs to the field of adjustable support construction technology for independent bridge pier cap beam construction, and particularly relates to an adjustable support construction bracket and method for independent bridge pier cap beam construction. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a pier or pile frame to support, distribute, and transfer the load of the superstructure. It is also called a cap beam. A reinforced concrete or lightly reinforced concrete horizontal beam is installed on the pier (apron) or pile frame. Its main function is to support the superstructure of the bridge and transfer all the load to the substructure.

[0003] A search revealed a patent document with publication number CN206070387U, which discloses a steel truss support structure for bridge pier cap beam construction. This structure is installed on pre-cast concrete pier columns, with pre-drilled holes in the upper part of the columns. Steel bars are inserted into these holes. Steel supports are symmetrically installed at both ends of the steel bars, and platform lifting and adjusting devices are symmetrically installed on the supports. A load-bearing steel truss platform is mounted on the lifting and adjusting devices, which are supported by the lifting and adjusting devices of two adjacent concrete pier columns. Pads are placed on the load-bearing steel truss platform, and standardized steel formwork is installed on these pads. This support structure exhibits high strength and rigidity, and is structurally reliable. It can shorten the construction time of bridge pier cap beams, ensure the rapid formation of the steel truss support, improve the construction safety of the support system, achieve stability of the bridge pier cap beam formwork, and guarantee the high-quality technical effect of dense concrete pouring for the cap beam.

[0004] However, the above structure still has shortcomings. When fixing the load-bearing steel truss platform, a cross-shaped planar structure is generally used for reinforcement and stability. However, the existing cross-shaped planar structure is generally fixed by welding, which has the disadvantages of inconvenient disassembly and difficult adjustment.

[0005] Therefore, it is necessary to provide a new adjustable support construction scaffold and method for the construction of independent bridge pier cap beams to solve the above-mentioned technical problems. Summary of the Invention

[0013] As a further embodiment of the present invention, the first support column and the two second support columns are provided with the same first base plate, and the first base plate is provided with a first support mechanism. The first support mechanism includes two load-bearing steel truss platform units, a second base plate and a transverse distribution beam unit. The two load-bearing steel truss platform units are both set on the first base plate. The load-bearing steel truss platform unit is composed of two I-shaped seats, a vertical fixing rod, a square connecting plate, an I-shaped seat, and a prismatic connecting frame.

Then adjust their positions according to the specifications of the cross-shaped horizontal bracing, and then fix them.

[0020] S2: When fixing, the first fixing block is slidably installed on the two second mounting blocks. During the sliding process, the L-shaped block is pulled to move, so that it squeezes the return spring through the L-shaped block.

Then, the second fixing block is inserted into the first fixing block, the second fixing block and the first fixing block. During the insertion process;

[0021] S3: While the second fixed insert block drives the rack to move, the meshing action drives the gear to rotate, which in turn drives the corresponding gear to rotate. This rotation then drives the take-up wheel. Under the action of the fourth, third, second, and first guide wheels, the stop block is pulled to move, causing the stop block to move the third fixed insert block. This, in turn, stretches the telescopic spring, causing the third fixed insert block to insert into the second fixed insert block. This limits and fixes the second fixed insert block. Finally, bolts are used to install the cross-shaped parallel coupling onto the corresponding first mounting block.
