Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a supporting structure for widening a bridge. Background Art

[0002] When widening a bridge, after all the T-beams of the bridge to be widened have been erected and pre-stressed and left empty for half a year, prestressed high-strength precision-rolled threaded coarse steel bars shall be tensioned. Before tensioning, channel steels shall be installed on both longitudinal sides of the connecting cross-partitions and wedged to prevent deformation of the beam.

[0003] When setting channel steel between T-beam ribs, since the length of the channel steel is fixed, it is time-consuming and labor-intensive to place the channel steel. Pads are also required to ensure that the channel steel is wedged tightly, which affects the bearing capacity of the channel steel and causes deformation of the beam body. At the same time, it is also time-consuming and labor-intensive to remove the channel steel from between the transverse partitions. Moreover, due to the different distances between the transverse partitions, channel steels of different lengths need to be cut, further reducing construction efficiency.

[0004] Therefore, it is urgent to design a support structure for widening the bridge to solve the above-mentioned problems. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0027] Please refer to the attached Figure 1 To the attached Figure 6 The utility model describes a supporting structure for widening a bridge.

[0028] At present, when setting channel steel between the transverse partitions, since the length of the channel steel is fixed, it is time-consuming and labor-intensive to place the channel steel. Pads are also required to ensure that the channel steel is wedged tightly, which affects the bearing capacity of the channel steel and causes deformation of the beam body. At the same time, it is also time-consuming and labor-intensive to remove the channel steel from between the transverse partitions. Moreover, due to the different distances between the transverse partitions, channel steels of different lengths need to be cut, further reducing construction efficiency.

[0029] Therefore, this supporting structure includes a first supporting plate 11, which is connected to the rib 1 at the transverse diaphragm of the old bridge T-beam in a supporting state. A first connecting tube 12 is fixedly connected to the first supporting plate 11, and a second connecting tube 31 is provided on the first connecting tube 12. The second connecting tube 31 can slide relative to the first connecting tube 12, and a connecting rod 22 is provided on the second connecting tube 31. When the second connecting tube 31 slides relative to the first connecting tube 12, the connecting rod 22 slides relative to the second connecting tube 31 in the sliding direction of the second connecting tube 31. The end of the connecting rod 22 away from the second connecting tube 31 is fixedly connected to the second supporting plate 21, and the second supporting plate 21 is connected to the rib 2 at the transverse diaphragm of the new bridge T-beam in a supporting state.

[0030] First, place the support structure between the rib 1 at the old bridge T-beam diaphragm and the rib 2 at the new bridge T-beam diaphragm, then connect the first support plate 11 to the rib 1 at the old bridge T-beam diaphragm, and then slide the second connecting tube 31 in the direction away from the first connecting tube 12. At this time, the second support plate 21 slides in the direction away from the first connecting tube 12 at the same time, and then can slide relative to the second connecting tube 31 through the connecting rod 22. When the second connecting tube 31 slides in the direction away from the first connecting tube 12, the connecting rod 22 slides relative to the second connecting tube 31 in the sliding direction of the second connecting tube 31, thereby The sliding speed is accelerated to twice the sliding speed of the second connecting tube 31 until the second support plate 21 is connected to the rib 2 at the new bridge T-beam diaphragm, so that the support structure is easy to place when placed between the rib 1 at the old bridge T-beam diaphragm and the rib 2 at the new bridge T-beam diaphragm. Subsequently, the first support plate 11 is connected to the rib 1 at the old bridge T-beam diaphragm, and the second support plate 21 is connected to the rib 2 at the new bridge T-beam diaphragm, which ensures the support of the support structure. At the same time, it can adapt to different distances between the rib 1 at the old bridge T-beam diaphragm and the rib 2 at the new bridge T-beam diaphragm, saving time and effort, and facilitating the recovery of the support structure.

[0031] Preferably, the connection method between the first support plate 11 and the rib 1 at the cross-diaphragm of the old bridge T-beam and the connection method between the second support plate 21 and the rib 2 at the cross-diaphragm of the new bridge T-beam can be wedge-jointed. In other embodiments of the present invention, other connection methods can also be selected as long as the support effect of the support structure between the cross-diaphragms can be met.

[0032] The first connecting tube 12 is provided with a first slot 15, and the second connecting tube 31 is slidably connected to the first slot 15. Threads are provided on the outer walls of the first slot 15 and the second connecting tube 31. The first slot 15 and the second connecting tube 31 are screwed together, so that when the second connecting tube 31 is rotated, the second connecting tube 31 can slide relative to the first slot 15. This support structure is thus placed between the rib 1 of the old bridge T-beam diaphragm and the rib 2 of the new bridge T-beam diaphragm. After connecting the first support plate 11 to the rib 1 of the old bridge T-beam diaphragm, the second connecting tube 31 is rotated, causing it to slide toward the end away from the first connecting tube 12.

[0033] Preferably, the second connecting tube 31 is fixedly connected to a rotating block 3 ; by providing the rotating block 3 , the second connecting tube 31 can be easily rotated manually.

[0034] When the second connecting tube 31 is rotated and slides in the direction away from the first connecting tube 12, the connecting rod 22 slides synchronously in the direction away from the first connecting tube 12 on the basis of the second connecting tube 31, so that the sliding speed of the connecting rod 22 is twice that of the second connecting tube 31, so that when the second connecting tube 31 is stored or unfolded, the speed is fast, which saves the time of screwing the second connecting tube 31.

[0035] A limiting rod 23 is fixedly connected to the second support plate 21, and a limiting plate 13 is fixedly connected to the first connecting tube 12. A limiting groove 14 is provided on the limiting plate 13. The limiting rod 23 is slidably connected to the limiting groove 14. Both the limiting rod 23 and the limiting groove 14 are rectangular. By setting the limiting rod 23 and the limiting groove 14, the second support plate 21 and the connecting rod 22 will not rotate when sliding, so that the connecting rod 22 can slide relative to the second connecting tube 31.

[0036] Furthermore, the first connecting cylinder 12 , the second connecting cylinder 31 and the connecting rod 22 are all located on the same axis.

[0037] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
