Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to an adjustable cap beam support transverse slope regulating device and a bridge structure. Background Art

[0002] At present, in the construction of bridge cap beam structures, due to the design of the transverse slope, the cap beam support has a certain transverse slope during the construction process. In traditional cap beam construction, the transverse slope is usually achieved by adjusting the height of the steel pipe column, the height of the sand box or installing I-beams of different sizes. However, the traditional construction method requires special design of the steel pipe column, sand box or I-beam according to the design height and specifications of each cap beam, which requires a large amount of construction. In addition, the transverse slope achieved by the above method is that the I-beam is in a vertical state, while the Bailey beam is in an inclined state. It is impossible to ensure that the lower surface of the Bailey beam is in full contact with the upper surface of the I-beam, which will inevitably cause the I-beam to be stressed only at the support point, affecting the stability of the support.

[0003] Chinese patent document CN117328340A (202311538718.1) discloses a support with adjustable transverse slope, a bridge structure and its construction method, including a support structure, the support structure including a steel box beam, the upper end surface of the steel box beam is provided with a plurality of height adjustment devices at intervals, each of the height adjustment devices can be adjusted individually, and the heights of two adjacent height adjustment devices decrease or increase in sequence, the upper end of the height adjustment device is provided with a support device, the upper end of the support device is abutted against a transverse distribution beam, and the transverse slope of the transverse distribution beam is adjustable by providing a plurality of height adjustment devices at the lower end of the transverse distribution beam. The above technical solution uses a height adjustment device, a triangular support device and a transverse distribution beam to replace the I-beam, so that the transverse distribution beam and the bottom template fit together, ensuring the stability of the entire support structure. However, since the transverse distribution beam is inclined and the support device is vertically arranged, the support device will be subjected to lateral forces, and a truss structure must be used to enhance the strength of the support device, and the manufacturing process is complicated. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable cap beam support transverse slope adjustment device and a bridge structure, which utilizes a telescopic device to adjust the angle between the top panel and the bottom panel to adapt to cap beams with different transverse slope angles, and the axis of the telescopic device is perpendicular to the top panel to ensure that the telescopic device only bears axial force, thereby solving the current problems of stability and frequent adjustment of the cap beam support, and helping to promote the development of similar engineering construction technology in the future.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: an adjustable cap beam support transverse slope adjustment device, comprising a top panel, a bottom panel and a telescopic device;

[0006] The bottom panel is arranged horizontally, the top panel is located above the bottom panel, and a plurality of telescopic devices are arranged between the top panel and the bottom panel along the length direction of the bottom panel, wherein the axial length of the telescopic devices decreases or increases in sequence along the length direction of the bottom panel;

[0007] The upper end of the telescopic device is connected to the top panel, and the axis of the telescopic device is perpendicular to the top panel;

[0008] The lower end of the telescopic device is connected to the bottom panel, which is connected to the sand box, and the Bailey beam is connected to the top panel via the I-beam, thereby ensuring that the external force on the Bailey beam is transmitted to the bottom panel along the axial direction of the telescopic device, ensuring that the telescopic device does not bear bending force.

[0009] Preferably, one end of the top panel is hingedly connected to one end of the bottom panel. Hinging one end of the top panel and one end of the bottom panel facilitates assembly of the entire adjustment device, making the connection between the structures of the entire adjustment device more secure, and facilitating adjustment of the angle between the top panel and the bottom panel, thereby achieving the use of different angles of horizontal slope.

[0010] The present invention preferably further includes an adjustment base, which is disposed between the telescopic device and the bottom panel, with the upper end surface of the adjustment base parallel to the top panel and the lower end surface of the adjustment base parallel to the bottom panel. The adjustment base is used to adjust the angle between the axis of the telescopic device and the bottom panel to adapt to different horizontal slopes.

[0011] Preferably, the adjustment base is a wedge-shaped block. The wedge-shaped block is set at a corresponding angle according to the horizontal slope angle to ensure that the axis of the telescopic device is perpendicular to the top panel. Since the wedge-shaped block has a simple solid structure, it can be directly welded or bolted to the bottom panel.

[0012] Preferably, the lower end of the telescopic device is hingedly connected to the bottom panel. By hingedly connecting the lower end of the telescopic device to the bottom panel, the angle between the axis of the telescopic device and the bottom panel can be adjusted according to the horizontal slope angle, so that the axis of the telescopic device is perpendicular to the top panel, which is more convenient and quick to use.

[0013] Preferably, the telescopic device includes a jack. The jack is used to support the upper cap beam, which can withstand a larger load.

[0014] Preferably, the telescopic device of the present invention comprises a threaded telescopic rod.

[0015] The utility model also discloses a bridge structure, comprising columns, a sand box, an I-beam and a Bailey beam, and also comprising the above-mentioned adjustable cap beam support transverse slope adjustment device;

[0016] The flask is arranged at the upper end of the column, the bottom panel is fixedly connected to the flask, the lower end of the I-beam is connected to the top panel, and the Bailey beam is arranged at the upper end of the I-beam.

[0017] Preferably, the I-beam is a double-jointed I-beam, which is a type of I-beam that differs from conventional I-beams in that it is double-jointed to provide it with higher strength and stability.

[0018] Compared with the prior art, the present invention has the following advantages: the bottom panel is positioned horizontally, the top panel is positioned above the bottom panel, and multiple sets of telescopic devices are spaced along the length of the bottom panel between the top and bottom panels, ensuring support strength while also adjusting the angle between the top and bottom panels to accommodate different transverse slopes of the cap beam. The bottom panel is connected to the sandbox, and the I-beam is connected to the top panel, thereby ensuring full contact between the I-beam and the bottom of the Bailey beam, ensuring the stability of the overall support structure of the adjustment device.

[0019] Since the axis of the telescopic device is perpendicular to the top panel, the pressure borne by the cap beam can be transmitted to the bottom panel below along the axial direction of the telescopic device, avoiding damage to the telescopic device due to bending force, thereby improving the overall strength and service life of the adjustment device.

[0020] The regulating device of the utility model is convenient and quick to construct in the bridge structure and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS
