Description

Technical Field

[0001] The utility model belongs to the technical field of bridge structures, and in particular relates to a single-track or double-track bridge structure. Background Art

[0002] In order to meet the traffic demand, the box girder of a single-track bridge usually needs to be widened, and more materials need to be used than before, which results in its own heavy weight. Prefabrication and then lifting it above the bridge pose safety hazards and waste a lot of manpower, material and financial resources. Therefore, cast-in-place technology is used to avoid the above problems. When the bridge deck demand is too large, continuing to widen the box girder will affect the safety and applicability of the entire bridge. In order to ensure the stability and safety of the bridge, the single-track bridge needs to be transitioned to a double-track bridge for a split-section design. The box girder of the double-track bridge can achieve width reduction and weight reduction due to the split-section, and can be made using a more convenient prefabrication process. Since the single-track bridge and the two-way bridge are not cast as one, the general connection method has the problem of poor connectivity.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0027] like Figure 1-3 As shown, a single-track and double-track bridge structure includes a splicing structure and a fixed structure; the splicing structure includes a splicing groove 1 and a splicing block 2, the splicing groove 1 is located at the end face of the double-track bridge, and the splicing block 2 is located outside the end face of the single-track bridge, and the splicing is completed by the splicing block 2 extending into the splicing groove 1, the fixed structure includes a connecting groove 3, a connecting block 4, and a connecting plate 6, the connecting groove 3 is opened at the top of the double-track bridge, the connecting groove 3 and the splicing groove 1 are connected, and a card slot 5 is provided on the upper surface of the splicing block 2, and the connecting block 4 extends into the upper surface of the splicing block 2 in the splicing groove 1 through the connecting groove 3 to be carded with the groove on the upper surface of the splicing block 2, which fixes the splicing block 2 and stabilizes the splicing part, and the connecting plate 6 is fixedly arranged at the splicing part of the single-track bridge and the double-track bridge, and the connecting block 4 is fixedly connected to the connecting plate 6 to ensure the stability of the splicing part of the entire bridge.

[0028] like Figure 3 As shown, the two ends of the connecting plate 6 along the bridge direction are respectively embedded in the single-track bridge and the double-track bridge. The top surface height of the connecting plate 6 is respectively consistent with the bridge deck height of the corresponding single-track bridge and double-track bridge, ensuring the flatness of the overall bridge deck and effectively avoiding safety hazards caused by uneven roads.

[0029] like Figure 3As shown, the connecting plate 6 fixing cover is arranged at the joint of the single-track bridge and the double-track bridge, which can effectively increase the bearing capacity and stability of the joint and avoid the joint from being adversely affected by passing vehicles passing over the joint.

[0030] like Figure 6 As shown, the gaps between the connecting plate 6 and the single-track bridge and the double-track bridge are filled with buffer material 9. The buffer material 9 can effectively reduce the pressure on the bridge caused by passing vehicles, reduce damage to the bridge, and prevent deformation at the joints.

[0031] like Figure 3 As shown, the connecting plate 6 is detachably fixed at the joint of the single-track bridge and the double-track bridge by screws 7. The connecting plate 6 can be replaced or the size of the connecting plate 6 can be adjusted by removing the screws 7, saving a lot of time and work costs.

[0032] like Figure 6 As shown, the double-track bridge adopts a single-box single-chamber 10 box girder, and the single-track bridge adopts a single-box double-chamber 11 box girder. The single-box single-chamber 10 adopted in the double-track bridge has the advantages of uniform force, strong bending resistance and strong torsion resistance. Because the single-track bridge often widens the road to meet the traffic needs, the use of a single-box double-chamber 11 box girder can appropriately reduce the deadweight of the box girder and avoid affecting the stability of the bridge structure.

[0033] like Figure 5 As shown, rubber material 8 is provided inside the connecting groove 3, the splicing groove 1 and the card groove 5, which can avoid hard collision during fixed installation and damage to the device, and also has a certain buffering effect.

[0034] Through the design of the splicing structure, the two bridges can be accurately docked, which improves the accuracy. The slot 5 opened on the top of the splicing block 2 is then snapped into the connecting block 4 to effectively fix the splicing between the bridges. The connecting plate 6 is fixedly arranged at the splicing of the single-track bridge and the double-track bridge, which can further improve the stability of the splicing of the single-track bridge and the double-track bridge, and at the same time can also protect the bridge deck at the splicing.

[0035] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
