Description

Technical Field

[0001] This utility model relates to the field of building structures, specifically to a connection reinforcement device between a Bailey beam and a steel column. Background Technology

[0002] Bailey bridge panels, also known as Bailey trusses, Bailey beams, or trusses, were first invented during World War II by a British engineer to address the need for rapid bridge erection during the war, and were named after him. Bailey bridge panels are characterized by their simple structure, convenient transportation, rapid erection, large load capacity, good interchangeability, and strong adaptability. Therefore, they are widely used in highway bridges, gantry cranes, guide beams, bridge erecting machines, and suspended platforms. Bailey truss combination gantry cranes utilize prefabricated highway steel bridge components to assemble the gantry frame, and their span and column height are adjustable to adapt to different working sites. They are widely used in highway, railway, municipal, building, and water conservancy construction projects, as well as in bridge construction prefabrication yards for lifting and moving prefabricated components and transporting large beams beside bridge piers.

[0003] The existing connection between Bailey bridges and steel columns is mostly achieved by setting a load-bearing beam horizontally on the steel column and placing the Bailey bridge on the load-bearing beam. However, most existing methods involve placing the Bailey bridge directly on the load-bearing beam without any connection structure between it and the steel column, resulting in poor overall structural integrity between the two.

[0004] To address this, we propose a reinforcement device for the connection between Bailey beams and steel columns. Summary of the Invention

[0005] To address the aforementioned shortcomings of the existing technology, this utility model provides a strengthening device for the connection between Bailey beams and steel columns.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A reinforcement device for connecting a Bailey beam and a steel column includes: a steel column; a load-bearing beam horizontally mounted on the top of the steel column; a Bailey beam placed on the load-bearing beam; and a reinforcement structure mounted on the steel column and connected to the Bailey beam, wherein the reinforcement structure is used to strengthen the structure between the steel column and the Bailey beam.

[0008] By mounting the load-bearing beam onto the steel column, the connection between the load-bearing beam and the steel column is strengthened, and the problem of non-removable welding fixation is avoided. Setting up a reinforcing structure to connect the steel column and the Bailey beam can effectively strengthen the connection structure between the Bailey beam and the steel column, and improve the overall integrity and structural strength of the device.

[0009] Further specified, both the steel column and the load-bearing beam are I-beams. The top of the steel column is equipped with a snap-fit ​​part, the outer diameter of which matches the inner diameter of the I-beam opening of the load-bearing beam. The load-bearing beam is H-shaped and snapped onto the snap-fit ​​part. The snap-fit ​​part is formed by cutting the wing plate at the top of the steel column to match the I-beam opening of the load-bearing beam. Snapping the load-bearing beam onto the snap-fit ​​part can effectively prevent the load-bearing beam from slipping and improve the stability of the device.

[0010] Further defining and strengthening the structure includes gusset plates and connecting bars. The gusset plates are mounted on steel columns and have several vertically formed connecting holes. One end of each connecting bar is bolted to a connecting hole, and the other end is bolted to a Bailey beam. By mounting the gusset plates on the steel columns and connecting bars connecting the steel columns and Bailey beams, a right-angled triangle is formed between the connecting bars, the steel columns, and the Bailey beams. The connecting bars, acting as the hypotenuse of the right-angled triangle, provide support for the Bailey beams, resulting in higher structural strength.

[0011] Further defining the Bailey beam, it includes a male and a female plug located on both sides, with corresponding pin holes on both the male and female plugs. Adjacent Bailey beams are fixed by inserting the male plug into the female plug and passing the connecting bolt through the pin holes.

[0012] Further specified, the other end of the connecting bar is fixed by passing through the connecting bolt. The steel column is provided with node plates on both sides of the Bailey beam extension direction, and the number of connecting holes matches the number of connecting bolts. By connecting one end of the connecting bar to the Bailey beam to the connecting bolt, it can provide support for the connection point between two adjacent Bailey beams, prevent the Bailey beam from collapsing from the connection point, and effectively improve the strength.

[0013] The beneficial effects of this utility model are as follows: by fixing the load-bearing beam onto the steel column, the side slippage of the load-bearing beam is avoided and it can be disassembled. The structure is strengthened to connect the steel column and the Bailey beam, which enhances the overall integrity of the device, improves the strength of the Bailey beam connection point, and improves safety.

[0019] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious.

[0020] Example:

[0021] like Figures 1-3 As shown, a Bailey beam and steel column connection reinforcement device includes a steel column 1, a load-bearing beam 2, a Bailey beam 3, and a reinforcement structure 4. Both the steel column 1 and the load-bearing beam 2 are I-beams. The top of the steel column 1 is provided with a snap-fit ​​part 11, the outer diameter of which matches the inner diameter of the I-beam opening of the load-bearing beam 2. The load-bearing beam 2 is H-shaped and snapped onto the snap-fit ​​part 11. The Bailey beam 3 is placed on the load-bearing beam 2. The Bailey beam 3 includes a male insertion end 31 and a female insertion end 32 located on both sides. Pin holes are correspondingly opened on both the male insertion end 31 and the female insertion end 32. Adjacent Bailey beams 3 are connected through the male insertion end 31. The female plug is inserted into the male plug 32 and the connecting bolt passes through the pin hole to achieve fixation; the reinforcing structure 4 is set on the steel column 1 and is used to strengthen the structure between the steel column 1 and the Bailey beam 3; the reinforcing structure 4 includes a node plate 41 and a connecting rib 42. The node plate 41 is set on the steel column 1 and has several vertically opened connecting holes. One end of the connecting rib 42 is connected to the connecting hole by a bolt and the other end is connected to the connecting bolt to achieve fixation. The steel column 1 has node plates 41 on both sides of the Bailey beam 3 extension direction, and the number of connecting holes matches the number of connecting bolts.

[0022] By securing the load-bearing beam 2 to the steel column 1, the connection between the load-bearing beam 2 and the steel column 1 is strengthened, while avoiding the problem of non-removable welding fixation. The installation of a reinforcing structure 4 connecting the steel column 1 and the Bailey beam 3 effectively strengthens the connection structure between the Bailey beam 3 and the steel column 1, improving the overall integrity and structural strength of the device. A locking part 11 is formed by cutting the wing plate at the top of the steel column 1, matching the I-beam opening of the load-bearing beam 2. Locking the load-bearing beam 2 onto the locking part 11 effectively prevents lateral slippage of the load-bearing beam 2, enhancing the device's overall performance and structural strength. To ensure stability, the node plate 41 is placed on the steel column 1, and the connecting bar 42 connects the steel column 1 and the Bailey beam 3. The connecting bar 42, the steel column 1 and the Bailey beam 3 form a right-angled triangle. The connecting bar 42, as the hypotenuse of the right-angled triangle, provides support for the Bailey beam 3, thus increasing the structural strength. By connecting one end of the connecting bar 42 to the Bailey beam 3 to the connecting bolt, the connection point between two adjacent Bailey beams 3 can be supported, preventing the Bailey beam 3 from collapsing from the connection point and effectively improving the strength.
