Description

Technical Field

[0001] This utility model relates to the technical field of bridge engineering, and in particular to an adjustable combined component for Bailey beam support systems. Background Technology

[0002] Bridges play a vital role in my country's transportation development, serving as key nodes in the transportation network. They cross obstacles such as rivers, lakes, and valleys, making transportation routes more interconnected and efficient, expanding transportation coverage, and improving transportation efficiency. When encountering complex mountainous terrain or obstacles spanning rivers and seas during bridge construction, the Bailey bridge system, which is easy to install and has high strength, is often used. This is combined with a disc-lock scaffolding system, utilizing the adjustable support components of the scaffolding to adjust the bridge's pre-camber, slope, and elevation.

[0003] The combination of Bailey bridge beams and disc-lock bracing systems not only meets the load requirements during construction but also better ensures the accuracy of various design specifications. However, when a new bridge encounters existing structures beneath it and the clearance between them does not meet the installation height requirements of the Bailey bridge beam + disc-lock bracing system, this support system cannot meet the needs of on-site use. The traditional solution is to directly use Bailey bridge beams and adjust the height by inserting steel plates between the Bailey bridge beams and the supported bridge structure. This method is difficult to precisely control the support height, and due to the large weight of the supported structures, the installation of the steel plates is a significant undertaking, inconvenient for on-site construction, requires substantial manpower and resources, and impacts the construction schedule.

[0004] Currently, the combined Bailey bridge and disc-lock bracing system approach is unsuitable when a new bridge encounters existing structures beneath it, and the clearance between them does not meet the installation height requirements of the Bailey bridge + disc-lock bracing system. The traditional solution is to directly use Bailey bridges and adjust the height by inserting steel plates between the Bailey bridge and the supported bridge structure.

[0022] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0023] This utility model discloses an adjustable combined component for Bailey beam support systems.

[0024] Reference Figures 1-2 An adjustable modular component for a Bailey bridge support system includes a fixed base, a movable support 5, and a top support assembly 2. The fixed base is installed on the Bailey bridge and has a receiving portion for accommodating the upper chord of the Bailey bridge. The fixed base has a sliding hole 9 communicating with the receiving portion along the vertical direction. The movable support 5 has a sliding rod 10, which is slidably fitted within the sliding hole 9. The bottom of the movable support 5 is located on the upper chord of the Bailey bridge. The top support assembly 2 supports the main rib of the bottom formwork and is located on the movable support 5. This design not only offers fast construction speed, high efficiency, and easily guaranteed project quality, but also improves construction safety. The adjustable device occupies little space, is easy to meet on-site construction conditions, is highly adaptable, has low initial investment cost, and is reusable, providing a prerequisite guarantee for civilized construction and energy conservation.

[0025] The fixed base includes an upper clamp 3, a lower clamp 6, and a connecting plate 8. The bottom of the upper clamp 3 and the top of the lower clamp 6 abut against each other. The upper clamp 3 is welded from a 16mm thick steel plate. A φ50mm round hole is provided at the top of the upper clamp 3, with an inner top support. Two φ16mm positioning bolt holes are provided on the left and right sides of the upper clamp 3, spaced 60mm apart. A 30*10mm strip hole is provided on the left and right sides of the upper clamp to form a sliding hole 9. The strip hole is used for the sliding rod 10 of the movable support 5 to pass through, so that the upper clamp 3 and the movable support 5 are assembled into a whole. The sliding rod 10 is slidably fitted in the sliding hole 9 and the movable support in the horizontal direction. The lower clamp 6 is welded from a 16mm thick steel plate. Two φ16mm positioning bolt holes are provided on the left and right sides of the lower clamp 6, spaced 60mm apart. The lower clamp 6 is combined with the upper clamp 3 through the connecting plate 8 to form a whole. After the upper clamp 3 and the lower clamp 6 are installed, they form a receiving part to accommodate the upper chord of the Bailey beam.

[0026] A connecting plate 8 is positioned at the abutment point of the upper clamp 3 and the lower clamp 6. The connecting plate 8 has a positioning element 7 for fixing the upper clamp 3 and the lower clamp 6. The positioning element 7 is fixed to the upper chord web of the Bailey beam. The connecting plate 8 has an upper through hole communicating with the upper clamp 3 and a lower through hole communicating with the lower clamp 6. The positioning element 7 includes an upper bolt and a lower bolt. The upper bolt passes through the upper through hole and connects to the upper clamp 3, and the lower bolt passes through the lower through hole and connects to the lower clamp 6. The connecting plate 8 is made of 10mm steel plate. Two connecting plates 8 are respectively set on the left and right sides of the fixing seat. Each connecting plate 8 has an upper through hole and a lower through hole arranged vertically. These two through holes are φ20mm bolt holes with a center-to-center distance of 60mm. The connecting plate 8 and the positioning element 7 are used to connect the upper and lower clamps into a single fixing seat, facilitating the removal of the adjustable device. The bolts are tightened against the upper chord web of the Bailey beam, serving to position and fix the adjusting device.

[0027] The movable support includes a support plate and a base plate. The top support assembly 2 is set on the support plate, and the base plate is set at the bottom of the support plate for abutting against the upper chord of the Bailey beam. Since the movable support is slidably fitted into the fixed seat in the vertical direction by the sliding rod 10, the position of the movable support relative to the fixed seat is adjusted by sliding the sliding rod 10 after the base abuts against the upper chord of the Bailey beam, thereby adapting to the upper chord of the Bailey beam of different heights and having high applicability.

[0028] The top support assembly 2 includes a snap-fit ​​seat, a screw, and a threaded sleeve. The snap-fit ​​seat has a snap-fit ​​part for snapping into the main rib of the bottom mold. The screw is threadedly connected to the threaded sleeve, which is rotatably fitted onto a movable bracket. The screw is mounted on the snap-fit ​​seat. To facilitate rotation of the threaded sleeve, a nut can be fixed on the threaded sleeve, and the rotation of the threaded sleeve can be adjusted by turning the nut with a wrench. The snap-fit ​​seat has a snap-fit ​​part for snapping into the main rib of the bottom mold. This design ensures a stable connection between the top support assembly 2 and the main rib of the bottom mold, preventing loosening or displacement during construction. The stable snap-fit ​​connection helps improve the stability of the entire support system and ensures safety during construction. The screw is threadedly connected to the threaded sleeve, allowing the screw to rotate freely and move axially within the threaded sleeve, thereby achieving height adjustment of the main rib of the bottom mold and improving applicability. The design of the top support assembly 2 makes its installation and disassembly relatively simple and quick, helping to shorten the construction cycle.

[0029] This utility model has a simple structure, low cost for one-time installation, and can be reused, improving the utilization rate of construction resources and effectively reducing construction waste on the construction site. The device is manufactured in the processing plant and has almost no impact on the surrounding environment. It reduces the amount of steel used in technical measures, greatly reduces social energy consumption, promotes the development of green buildings, and meets the needs of building a low-carbon and environmentally friendly society.

[0030] When working on the Bailey bridge assembly site, the components of this utility model can be installed together with the Bailey bridge, reducing high-altitude work and improving safety. Based on the position of the main ribs of the frame designed for the formwork support system, the processed upper clamp 3 and lower clamp 6 are installed and fixed to the upper chord position of the Bailey bridge via connecting plates 8. The four positioning bolts of the clamps are then tightened and locked to the upper chord web of the Bailey bridge to prevent the clamps from shaking. After the upper clamp 3 and lower clamp 6 are assembled with the Bailey bridge on the ground, they are hoisted into place as a whole, and then the main ribs of the bottom formwork are placed on the clamping seats.

[0031] This article uses specific examples to illustrate the principles and implementation methods of this utility model.
