Description

Technical Field

[0001] The present invention relates to the field of forming of steel bar structures for bridge girders, and particularly to an apparatus for manufacturing steel bar components of segmental girders and a manufacturing method thereof. Background Art

[0002] Transportation accounts for an increasingly large proportion in economic development, and bridges are an essential and important part of transportation facilities. With the increasing maturity of bridge construction technology, in order to save land resources and increase the traffic capacity of vehicles or ships under and on the bridge, reinforced concrete box girders are also developing towards larger box girders that are longer and wider, and the steel bar structures of box girders are getting larger and heavier, which brings new challenges to the construction of box girder steel bar structures.

[0003] The steel bar components of large segmental girders have characteristics such as structural interlocking, extremely large spans and cross-sections. In traditional construction methods, at the construction site of segmental girder steel bars, the most common construction method is to manually carry steel bars into the external formwork of segmental girders for positioning, binding or welding. The construction intensity is high, the construction efficiency is low, and it is also difficult to ensure the production cycle of segmental girder steel bars; due to the large size of segmental girders, a large amount of manpower is required, which belongs to labor-intensive operations, and the safety risk at the construction site is increased invisibly; at the same time, due to the uneven technical levels of workers, it is difficult to ensure the construction quality of segmental girder steel bars. At present, there is also a method of using prefabricated steel bar mesh sheets for assembly to construct segmental girder steel bars. However, due to the large flexibility of steel bar mesh sheets, each mesh sheet needs to add more lifting points to prevent lifting deformation, which not only increases the lifting cost, but also makes it difficult to ensure the final assembly quality. Therefore, this method is difficult to be widely used in the construction of segmental girder steel bars.

[0004] Currently, society's requirements for the construction efficiency, quality, safety, etc. of large bridges are constantly increasing. Therefore, the future development trend in the steel bar field will be the manufacturing of steel bar components of segmental girders. Summary of the Invention

This process should not be used to circumvent the other solutions of this patent; if the steel bar mesh only contains one steel bar unit, there is no process of assembling and connecting other units.

[0066] The steel bar parts of the segmental assembled box girder manufactured by the technical solution are divided into several small blocks for forming, and the overall stiffness of the blocks is relatively large, and the blocks are not easily deformed during transportation, hoisting and assembly. Therefore, this process is suitable for the manufacture of the steel bar parts of the segmental assembled box girder.

[0067] In the solution, the shapes of each mesh and the blocks are described by taking the steel bar structure of the double-chamber segmental assembled box girder as an example. Therefore, the structural shapes of the two should not be used as limiting conditions for the solution of the present invention; the forming of the steel bar mesh and the steel bar blocks can be considered by using artificial jigs or by mechanical means. Therefore, the forming process should not be used as a limiting condition for the solution of the present invention; the assembly process of the steel bar blocks into steel bar parts according to the technological sequence is described by taking the steel bar structure of the double-chamber segmental assembled box girder as an example. Therefore, the assembly sequence should not be used as a limiting condition for the solution of the present invention.

The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
