Description

Technical Field

[0001] This application relates to the technical field of the support of temporary girder piers, and particularly relates to an instability righting bracket for temporary girder piers. Background Technique

[0002] The construction of the temporary girder under the railway refers to a bridge structure built under the railway line, which is used to support and carry the girders on which the tracks are laid above the railway. This structure is often used when the railway intersects with other transportation lines (such as roads, rivers, etc.) to ensure the safe and smooth passage of various transportation lines.

[0003] In an existing temporary girder support system mentioned in a Chinese patent (authorized announcement number: CN220335734U), when erecting a large-span temporary girder for the jacking construction of a bridge and culvert with a large span and a large skew angle, it can provide stable support, reduce the construction steps of temporary support and system conversion, save construction time, reduce construction costs, and shock-absorb the vibration generated by the train passing above the cross-lifting beam through the hydraulic rod and the spring around it, thereby improving the service life of the system.

[0004] The existing under-railway overpasses often use the method of prefabricating the box body in the foundation pit and jacking it. When jacking the box body, it is necessary to erect a temporary girder to ensure the normal operation of the railway. The temporary girder piers are often constructed by erecting temporary girders, excavating trenches under the line, constructing high-pressure jet grouting piles, and pouring concrete strip foundations. However, in on-site construction, sandbags or wooden sleepers are often used for the support of the piers. Such temporary support facilities are simple and may cause unsafe factors, and are not conducive to the stability of the temporary girders. Content of the Utility Model

[0032] The following is combined with Figures 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a support for straightening an unstable temporary beam pier.

[0034] Reference Figure 1 and Figure 2 A support bracket for straightening an unstable temporary beam pier comprises two symmetrically arranged pier bodies 1, a transverse temporary beam 2 is fixedly connected to the top of the pier body 1, a plurality of vertical temporary beams 3 are fixedly connected at equal intervals between the two transverse temporary beams 2, a railway 4 is overlapped on the top of the vertical temporary beams 3, a foundation soil 5 is arranged below the pier body 1, a foundation pit 6 is opened inside the foundation soil 5, and a supporting mechanism is arranged inside the foundation pit 6.

[0035] During the construction of the temporary beam, the foundation pit 6 is excavated first. By excavating the foundation pit 6 under the temporary beam, sufficient supporting space can be provided for the temporary beam to ensure that the temporary beam will not collapse or become unstable during construction under the railway 4. Then, the pier body 1 is installed on the top of the base soil 5 to ensure verticality and horizontality. Then, the transverse temporary beam 2 is fixedly connected to the top of the pier body 1. Then, a number of vertical temporary beams 3 are equidistantly arranged on the transverse temporary beam 2. The vertical temporary beams 3 are fixedly connected to the railway 4 to ensure the stability and bearing capacity of the pier body 1. Finally, the transverse temporary beams 2 and the vertical temporary beams 3 are checked to ensure that the connection is firm and meets the design requirements. The pier body 1 can be supported by the supporting mechanism to provide additional support and fixation to the pier body 1, thereby enhancing the stability of the pier body 1 and effectively reducing the safety problems caused by the instability of the pier body 1.

[0036] Reference Figure 2 and Figure 3The supporting mechanism includes a supporting rod 7 fixedly arranged inside the foundation pit 6, the top of the supporting rod 7 is fixedly connected with a resistance block 8, the top of the resistance block 8 is fixedly connected with a top plate 9, the top of the top plate 9 is fixedly connected to the vertical temporary beam 3, and the outer surface of the supporting rod 7 is provided with a reinforcement.

[0037] Among them, the outer surface of the support rod 7 is fixedly connected to a mounting seat 28, and the outer surface of the mounting seat 28 is equidistantly fixedly connected to a plurality of rotating seats 10, the interior of the rotating seat 10 is rotatably connected to a slide cylinder 11, the interior of the slide cylinder 11 is slidably connected to a slide rod 12, and the bottom of the slide rod 12 is rotatably connected to a connecting plate 13.

[0038] In addition, a plurality of friction blocks 14 are fixedly connected to the bottom of the connecting plate 13 at equal intervals, and the friction blocks 14 are arranged in a cone shape.

[0039] When supporting the pier body 1, first fix the support rod 7 inside the foundation pit 6, then weld the abutment block 8 on the top of the support rod 7, and then weld the top plate 9 on the top of the abutment block 8. The support rod 7, the abutment block 8 and the top plate 9 can provide additional support for the pier body 1, increase the bearing capacity of the pier body 1, reduce the risk of the pier body 1 moving or overturning, and improve the stability and safety of the pier body 1 under various loads. After the support rod 7 is installed, rotate the slide cylinder 11 to a suitable angle, and then the slide rod 12 is fixed to the bottom of the support rod 7. The interior of the slide tube 11 slides to a suitable position, and the position of the slide rod 12 can be fixed by passing bolts through the slide tube 11 and threadedly connected to several threaded grooves on the slide rod, so that the connecting plate 13 is in conflict with the ground of the foundation pit 6. The connecting plate 13 can increase the contact area between the support rod 7 and the ground, thereby improving the stability of the support rod 7, reducing the instability caused by the movement of the support rod 7, and helping to maintain the verticality and stability of the pier body 1. The friction block 14 at the bottom of the connecting plate 13 can increase the firmness of the support rod 7 and the ground.

[0040] Reference Figure 3 and Figure 4 The connecting plate 13 is rotatably connected to a rotating plate 17 on both sides thereof, and an insert rod 18 is slidably arranged inside the rotating plate 17. The bottom end of the insert rod 18 is provided with a cone, and the top end of the insert rod 18 passes through the rotating plate 17 and is fixedly connected to a striking block 19.

[0041] The internal thread of the connecting plate 13 is connected with a threaded rod 20 , one end of the threaded rod 20 passes through the connecting plate 13 and is rotatably connected with a fixing block 21 , and a rubber pad 22 is fixedly connected to a side of the fixing block 21 away from the fixing block 21 .

[0042] In addition, an auxiliary rod 23 is fixedly connected to one side of the fixing block 21 , and one end of the auxiliary rod 23 away from the fixing block 21 penetrates the connecting plate 13 , and the auxiliary rod 23 is slidably connected to the connecting plate 13 .

[0043] When the connecting plate 13 abuts against the ground, the staff rotates the rotating plate 17 to a proper position, then puts the inserting rod 18 into the rotating plate 17, and then uses a tool to strike the striking block 19 so that the inserting rod 18 penetrates into the foundation pit 6. By penetrating the inserting rod 18 into the foundation pit 6, the grounding depth of the support system can be increased, the firmness and stability of the support can be improved, so as to effectively support and protect the pier body 1. When the connecting plate 13 is in transit, the fixing block 21 is driven to move inside the connecting plate 13 by rotating the threaded rod 20, so as to fix the rotating plate 17 placed inside the connecting plate 13. After the rotating plate 17 is fixed inside, it can be more easily carried and installed, reducing collisions and damages during the carrying process, improving the transportation efficiency and the smoothness of construction. When the fixing block 21 moves, the auxiliary rod 23 provides an additional support point for the fixing block 21, making the fixing block 21 move more smoothly.

[0044] Refer to Figure 2 and Figure 3 As shown in, the reinforcing member includes a second mounting seat 24 fixedly connected to the outer surface of the support rod 7. Two cross plates 25 are fixedly connected to both sides of the second mounting seat 24. A vertical plate 26 is fixedly connected to the top of the cross plate 25. The top of the vertical plate 26 is fixedly connected to the abutting block 8. A reinforcing plate 27 is fixedly connected to the bottom of the cross plate 25. One end of the reinforcing plate 27 away from the cross plate 25 is fixedly connected to the support rod 7.

[0045] When supporting the top plate 9, the vertical plate 26 supports the abutting plate, and the abutting plate supports the top plate 9, thereby increasing the connection area between the abutting plate and the support rod 7. The increase in the connection area means a larger contact area of the support structure, which can effectively disperse the load and improve the bearing capacity of the support rod 7, thus improving the safety and stability of the pier body 1. Then, the reinforcing plate 27 makes a stable triangle formed among the support rod 7, the cross plate 25 and the reinforcing plate 27, thereby improving the compressive resistance of the support rod 7, the cross plate 25 and the reinforcing plate 27.

[0046] Working principle: First, the foundation pit 6 is excavated. The foundation pit 6 is excavated under the temporary beam, and then the pier body 1 is installed on the top of the foundation soil 5, ensuring the verticality and horizontality. Then, the transverse temporary beam 2 is fixedly connected to the top of the pier body 1. Then, a number of vertical temporary beams 3 are equidistantly arranged on the transverse temporary beam 2, and the vertical temporary beams 3 are fixedly connected to the railway 4, so as to ensure the stability and bearing capacity of the pier body 1. First, the support rod 7 is fixed inside the foundation pit 6, then the abutting block 8 is welded to the top of the support rod 7, and then the top plate 9 is welded to the top of the abutting block 8. The support rod 7, the abutting block 8 and the top plate 9 can provide additional support for the pier body 1.

[0047] The staff rotates the rotating plate 17 to a suitable position, then places the insertion rod 18 into the rotating plate 17, and then uses a tool to hit the striking block 19 to make the insertion rod 18 penetrate into the foundation pit 6. By penetrating the insertion rod 18 into the foundation pit 6, the grounding depth of the support system can be increased, and the firmness and stability of the support can be improved; when supporting the top plate 9, the vertical plate 26 supports the contact plate, and the contact plate supports the top plate 9, thereby increasing the connection area between the contact plate and the support rod 7. The increase in the connection area means that the contact area of ​​the support structure is larger, which can effectively disperse the load and improve the bearing capacity of the support rod 7.
