Description

Technical Field

[0001] The present invention relates to the technical field of steel truss arch-box beam hybrid bridges, and more particularly to a steel truss arch-box beam hybrid bridge capable of improving landscape and structural performance. Background Art

[0002] A truss arch bridge is constructed with a solid central section and arched truss segments on either side. The truss arch segments are connected by deck ties and transverse tie systems to form a single unit. A key characteristic of this type of bridge is that the solid central section and the arched truss segments act as the load-bearing arch, while the arch foot exerts a horizontal thrust that reduces mid-span bending moments. This type of bridge offers more balanced load-bearing than typical ribbed arch bridges with superstructures, saving material and reducing deadweight. It is suitable for applications with poor foundations. The fundamental concept of the box girder structure in a box girder bridge is that the entire superstructure becomes a single hollow beam. When the primary load passes through any location on the bridge, all sections of the hollow beam simultaneously participate in the load as a whole.

[0003] In reality, in order to better meet the actual traffic needs, construction designers will combine truss arch bridges and box beam bridges to build, which not only saves materials, but also increases the overall strength, thereby meeting the actual use needs. However, the middle part of the steel box beam structure in the existing box beam bridge will have insufficient support force. When the middle part of the steel box beam structure has insufficient support force, it is easy to cause the overall damage of the steel box beam structure, further resulting in a decrease in the actual stability of the bridge, thereby reducing the service life of the bridge; and the span of the bridge presents a sense of redundancy, the bridge shape is clumsy, and the landscape of the bridge is poor.

[0039] What is particularly noteworthy is that the steel box girder structure 2 is composed of a steel box girder 3, and two steel box girder holes 4 are provided on the steel box girder 3. What is particularly noteworthy is that a reinforcing plate 6 is provided in the steel box girder hole 4, and the reinforcing plate 6 is a concrete plate. At the same time, the material of the support plate 7 is the same as that of the reinforcing plate 6, and the staff can directly carry out construction in the steel box girder hole 4, thereby increasing the stability of the steel box girder 3.

[0040] It is also worth noting that two groups of inclined support plates 9 are provided on both sides of the stiffener plate 6, and the inclination directions of the two groups of inclined support plates 9 are symmetrical. At the same time, a second card groove 10 and a first card groove 8 are respectively provided on the steel box girder hole 4 and the stiffener plate 6.

[0042] It is particularly noteworthy that the material of the I-plate 15 is steel, and the I-plate 15 is located between one of the inclined support plates 9 and the steel box girder 3, so as to achieve the purpose of supporting the inclined support plate 9 below, further increasing the stability of the steel box girder 3.

The fixing screws 34 on the concrete pavement 5 can be used in conjunction with the threaded barrels to achieve the purpose of limiting the concrete pavement 5. At the same time, the gasket 35 can be sleeved between the concrete pavement 5 and the fixing screws 34, thereby increasing the stability of the fixing screws 34. When the concrete pavement reaches the end of its service life and needs to be replaced, it can be directly replaced without having to dismantle it.

[0045] At the same time, an I-shaped concrete block 16 is cast on the concrete pavement 5, and the I-shaped concrete block 16 is located below the concrete pavement 5, thereby supporting the concrete pavement 5, further reducing the use of concrete and further reducing costs. At the same time, a scissors-shaped steel plate 17 is provided in the I-shaped concrete block 16, and the scissors-shaped steel plate 17 is connected to the I-shaped concrete block 16 through a cement strip 19. At the same time, a cement support column 18 is cast between the scissors-shaped steel plate 17 and the I-shaped concrete block 16, thereby increasing the stability and support effect of the scissors-shaped steel plate 17, and with the assistance of the scissors-shaped steel plate 17 and the cement support column 18, the stability of the I-shaped concrete block 16 can be increased, thereby ensuring the strength and stability of the concrete pavement 5.

[0046] At the same time, a limiting hole is provided on the steel box girder 3, and the limiting hole can limit the limiter 20 on the concrete pavement 5. It is particularly noteworthy that the limiter 20 includes a limiting cylinder 21, and the lower end of the limiting cylinder 21 is provided with a second sealing ring 23. It is particularly noteworthy that the limiter 20 is fixed to the concrete pavement 5 by bolting, and the lower end surface of the limiting cylinder 21 is penetrated by a moving rod 24, and the moving rod 24 is slidably sealed with the second sealing ring 23. At the same time, the upper end of the moving rod 24 is fixedly connected to the piston plate 25, and the moving rod The lower end of 24 is fixedly connected to an abutment plate 26, and the lower end of the abutment plate 26 is fixedly connected to a protective steel plate 27, and the protective steel plate 27 is in the limiting hole. At the same time, it is particularly important to note that the limiting cylinder 21 is filled with hydraulic oil, and it is particularly important to note that the hydraulic oil is of a suitable volume to avoid the height of the concrete pavement 5 being different from other positions. When the limiting cylinder 21 is subjected to pressure, the limiting cylinder 21 can be moved accordingly, so that the hydraulic oil in the limiting cylinder 21 can be moved accordingly under the action of the piston plate 25.

When the hydraulic oil enters the top of the partition plate 28, the push plate 30 will move accordingly, and one end of the telescopic rod 31 is fixedly connected to the arc plate 32, so that the arc plate 32 can move accordingly. At the same time, a friction protection plate 33 is fixedly connected to the arc plate 32, so that the friction protection plate 33 can contact the limiting hole, so that the concrete pavement 5 can be limited. At the same time, the limiter 20 can also increase the strength of the concrete pavement 5, thereby ensuring the stability of the concrete pavement 5.

[0048] In the present invention, when the staff needs to use this device, the staff first bolts the steel truss arch structure 1 and the steel box beam structure 2 according to the construction specifications. Before that, the staff can first cast the stiffener plate 6 and the support plate 7 through a mold during the prefabrication of the steel box beam 3.

At the same time, the clip 11 can conveniently limit the expansion plate 14, and the staff can move the stiffener column 12 and the stiffener rod 13 through the gap between the two inclined support plates 9, which further facilitates the staff's work. At the same time, the staff can directly insert the I-plate 15 into the steel box beam 3, thereby achieving the purpose of supporting the inclined support plate 9.

[0049] After the steel truss arch structure 1 and the steel box girder structure 2 are installed, the staff can directly place the prefabricated concrete pavement 5 on top of the steel box girder 3, and then the staff can insert the fixing screws 34 into the steel box girder 3 to achieve the purpose of limiting the concrete pavement 5.
