Description

Technical Field

[0001] The utility model relates to the technical field of track beam construction, in particular to a supporting bracket device suitable for track beam construction of high-pile docks. Background Art

[0002] As an important part of the wharf structure, the cast-in-place rail beam of the high-pile wharf superstructure is a controlling construction task during the construction process. The construction of cast-in-place rail beams is not only a key element of the overall structural framework, but also plays a decisive role in ensuring the stability and load-bearing capacity of the wharf. Therefore, the construction quality of cast-in-place rail beams is directly related to the success or failure of the entire wharf project. However, due to the large deadweight of cast-in-place rail beams and the lack of sufficient support structure between the beams, it is difficult to obtain a stable and spacious working platform during construction, which undoubtedly brings many difficulties and challenges to the construction work.

[0003] In order to deal with this problem, the construction team usually adopts the conventional method of supporting the bottom formwork with the reverse bottom hanging method of fine-rolled threaded steel bars. This method uses the high strength and good anchoring performance of fine-rolled threaded steel bars to firmly fix the bottom formwork in the predetermined position, thereby providing the necessary working conditions for the construction of cast-in-place track beams. However, this reverse bottom supporting structure also has some problems that cannot be ignored. First, due to its large size and the space it occupies, it often interferes with other operations on the construction site and even affects the subsequent binding of the steel bars of the upper crossbeam structure. Secondly, due to the limited service life of the fine-rolled threaded steel bars, they need to be replaced regularly, which undoubtedly increases the maintenance cost and time cost during the construction process. In addition, the installation and disassembly cycle of the reverse bottom supporting structure is long, which is not conducive to continuous construction. Summary of the invention

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a support bracket device suitable for cast-in-place track beam construction, which has the advantages of being repeatedly used after installation and improving construction speed.

[0007] Furthermore, the corbel support component includes a corbel diagonal support and a corbel auxiliary support, the corbel auxiliary support is vertically installed on the cast-in-place pile below the track beam, one end of the corbel diagonal support is installed on one end of the corbel auxiliary support, and the other end of the corbel diagonal support is installed on the cast-in-place pile below the track beam.

[0008] Furthermore, the suspension arms disposed at both ends of the main load-bearing beam are inverted L-shaped suspension arms.

[0009] Furthermore, the corbel diagonal brace, corbel auxiliary brace and cast-in-place piles below the track beam are installed to form a triangular space.

[0010] The advantages and positive effects of the utility model are:
