Description

Technical Field

[0001] This utility model relates to the field of bridge structure technology, and in particular to a prefabricated cap beam support frame. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a pier to support, distribute, and transfer the load of the superstructure. Its main function is to support the superstructure of the bridge and transfer all the load to the substructure. During the construction of bridge cap beams, temporary support scaffolds are required to provide a working area for construction workers.

[0003] The cap beam of a bridge is located on top of the bridge piers. In conventional bridge construction, scaffolding and formwork are often required when constructing the cap beam. The construction period is long, the procedures are complex, and it is not environmentally friendly, which hinders its widespread use. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides a prefabricated cap beam support frame, aiming to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides a prefabricated cap beam support frame, comprising: a support frame body, a cap beam body disposed above the support frame body, and one or more cap beam bodies disposed parallel above the support frame body, with two cap beam bodies connected end to end locked and fixed together by a connector to form a prefabricated structure.

[0006] The design of the support frame body serves to fix and support the cap beam body. The number of cap beam bodies can be selected according to actual needs. When the corresponding installation is completed, the design of the connectors ensures the stability of the connection between the cap beam bodies.

[0007] Preferably, the support frame body includes uprights and cross braces. Two uprights are arranged in parallel and are made of steel. The cross braces are arranged on opposite sides of the two uprights and are welded to the uprights.

[0008] Compared to concrete columns, steel columns are lighter, making them easier to transport and install, shortening the construction cycle. Furthermore, steel is relatively inexpensive, requires less maintenance, and offers higher overall long-term benefits. The horizontal bracing design strengthens the column's support, while the welded design ensures the stability of the connection between the bracing and the column.

[0009] Preferably, the cap beam body includes distribution beams and connecting columns. Two distribution beams are arranged parallel to each other vertically, and the two distribution beams are connected by connecting columns. A stiffening triangular plate is provided at the connection between the connecting column and the distribution beam.

[0010] The upper and lower distribution beams are made of the same material, with the bottom distribution beam being longer than the top distribution beam. At least one connecting column is inclined between the upper and lower distribution beams to ensure the overall strength of the cap beam, and the stiffening triangular plate design ensures the stability of the connection between the connecting column and the distribution beam. The maximum stress of the main truss of the cap beam, σmax = 178.4 MPa < 305 MPa, meets the requirements. The maximum shear stress, max = 55.8 MPa < 175 MPa.

[0011] Preferably, it also includes a slope adjustment frame, which is set above the bottom distribution beam and has structural steel on it.

[0012] The slope adjustment frame utilizes existing commercially available structures in this field. By precisely adjusting the slope between the cap beam and the support, the frame ensures that the longitudinal and transverse slopes of the bridge match the design requirements, guaranteeing that the supports are under horizontal stress and preventing deformation or damage due to uneven stress. The steel sections provide safety protection. The maximum stress of the slope adjustment frame, σmax = 183.9 MPa < 215 MPa, meets the requirements, and the maximum shear stress, max = 82.3 MPa < 125 MPa. The above methods all employ common knowledge within this field and will not be elaborated upon further.

[0013] Preferably, it also includes auxiliary frames, with one or more auxiliary frames arranged parallel to each other below the bottom distribution beam, located on both sides of the column.

[0014] The auxiliary frame serves as a temporary support. In actual use, the appropriate number of auxiliary frames can be selected and installed according to actual needs.

[0015] Preferably, it also includes a sand discharge box, which is located at the connection between the column and the bottom distribution beam.

[0016] The unloading sand box adopts the existing structure in the market. With its functions of pressure dispersion, controllable unloading, and convenient construction, the unloading sand box balances safety and economy in bridge, building and other projects, and is a key device for temporary support and load transfer.

[0017] The beneficial effects of this utility model are:

[0018] When using this utility model, the number of cap beam bodies can be selected according to actual needs. When the corresponding installation is completed, the design of the connector ensures the stability of the connection between the cap beam bodies, realizing the assembly function. This design simplifies the process, shortens the construction cycle to a certain extent, and is conducive to its widespread use. Attached Figure Description
