Description

Technical Field

[0001] The utility model relates to the technical field of bridge reinforcement, in particular to a bridge reinforcement supporting structure. Background Art

[0002] A bridge refers to a structure erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. Bridges play a vital role in the modern transportation system. In order to ensure the safety of bridges, bridges need to be reinforced. Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by reinforcing components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation. In the process of bridge reinforcement, the supporting structure is the structure that reinforces the bridge and supports it.

[0003] The patent document with the announcement number CN218596957U discloses a support structure for bridge reinforcement. By setting up reinforcement components and utilizing the reinforcement components of the triangular support structure, the support columns of the support structure can be made more stable during support, thereby effectively improving the stability of the support structure, avoiding the tilting phenomenon of the support structure during use, and making the support effect of the support structure better... making the use effect of the support structure better.

[0004] The above technical solution still has some shortcomings in practical application. According to the principle of foundation settlement, we know that although the independent support column units on both sides are strengthened and supported, since the support columns and the base on both sides are separated independently, it is easy to cause interaction forces due to different stresses on the left and right during the load-bearing process. Over time, the two support units may experience foundation settlement deviation due to force interference, especially when the span is small, this situation is particularly obvious, making it difficult to ensure the stability and use effect of the support structure. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] Therefore, the purpose of the utility model is to provide a bridge reinforcement support structure to solve the problem that the bridge reinforcement support structure in the prior art proposed in the above background technology has interaction forces caused by different left and right stresses, which may cause the two support units to have foundation settlement deviation due to force interference over time, especially in the case of a small span, such a situation is particularly obvious, making it difficult to ensure the stability of the support structure and the use effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge reinforcement support structure, which includes a base, support columns are vertically installed at both ends of the top of the base, top plates are horizontally installed on the top of the two support columns, and multiple units of reinforcing hoops are fixedly connected to the support columns on both sides along their height direction, a longitudinal plate valve force-bearing structure is formed between the base, the support columns, the top plate and the reinforcing hoops, and the upper end of the top plate is elastically installed with a mounting pad for supporting the bridge frame.

[0008] As a preferred solution of a bridge reinforcement support structure described in the utility model, a metal pipe sleeve fixed integrally therewith is prefabricated on the outer peripheral side of the support column, and the length of the metal pipe sleeve is greater than the longitudinal arrangement stroke of multiple reinforcement hoops.

[0009] As a preferred solution of a bridge reinforcement support structure described in the utility model, the reinforcing hoop includes a first U-shaped clamp matched with the support column and the metal pipe sleeve and a second U-shaped clamp corresponding to the first U-shaped clamp, a positioning ear located at the end of the second U-shaped clamp and clamped with the first U-shaped clamp, a reinforcing rib connected to the inner side of the first U-shaped clamp and the inner side of the second U-shaped clamp, and a locking piece for fixing the reinforcing rib and the first U-shaped clamp / the second U-shaped clamp, and the positioning ear and the first U-shaped clamp.

[0010] As a preferred solution of a bridge reinforcement support structure described in the utility model, positioning base sleeves that match the ends of the support columns are prefabricated and fixed on both sides of the upper end of the base and both sides of the lower end of the top plate, and the positioning base sleeves are made of metal. The inner side of the positioning base sleeve also has a plurality of dowels embedded in the inner ends of the support columns.

[0011] As a preferred solution of the bridge reinforcement support structure described in the utility model, a plurality of ZFC-type shock absorbers for supporting and connecting the mounting cushions are also arranged on the top of the top plate.

[0012] As a preferred solution of the bridge reinforcement support structure described in the utility model, a plurality of positioning connectors for docking with the bottom of the bridge frame are also arranged on the top of the installation pad.

[0013] Compared with the prior art, the beneficial effect of the utility model is that this type of bridge reinforcement support structure can initially position and firmly connect the upper and lower ends of the support columns on both sides through the cooperation of the base, the top plate and the positioning base sleeve. At the same time, a reinforced connection is formed between the support columns on both sides through the cooperation of the metal pipe sleeve and the multi-unit reinforcement hoop sleeve. In this way, the entire support structure forms a firm longitudinal plate valve force structure, which effectively avoids the disadvantages of the existing support structure caused by the interference of prestressed force, such as the foundation settlement deviation and the difficulty in ensuring the stability and use effect of the support structure, and effectively improves the stability of the support structure through mutual cooperation.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Figure 1-Figure 4 The schematic diagram of the entire structure of a bridge reinforcement support structure of the utility model is shown. Figure 1-Figure 4 A bridge reinforcement support structure of the present embodiment includes a base 100, support columns 200 are vertically installed at both ends of the top of the base 100, top plates 300 are horizontally installed on the top of the two support columns 200, and multiple units of reinforcing hoops 500 are fixedly connected to the support columns 200 on both sides along their height direction. A longitudinal plate valve force structure is formed between the base 100, the support columns 200, the top plate 300 and the reinforcing hoops 500, and an installation pad 400 for supporting the bridge frame is elastically installed on the upper end of the top plate 300.

[0023] A metal pipe sleeve 210 fixed integrally therewith is also prefabricated on the outer peripheral side of the support column 200, and the length of the metal pipe sleeve 210 is greater than the longitudinal arrangement stroke of multiple reinforcing hoop sleeves 500. Here, the prefabricated metal pipe sleeve 210 can strengthen the connection firmness between the support column 200 and the reinforcing hoop sleeve 500, while also making the prestressing of the support column 200 more uniform and stable; in addition, the reinforcing hoop sleeve 500 and the metal pipe sleeve 210 can be welded, bolted or anchored during installation, as long as they can be firmly connected, and no specific limitation is made.

[0024] The reinforcing hoop 500 includes a first U-shaped clamp 510 matched with the support column 200 and the metal pipe sleeve 210 and a second U-shaped clamp 520 corresponding to the first U-shaped clamp 510, a positioning ear 521 located at the end of the second U-shaped clamp 520 and clamped with the first U-shaped clamp 510, a reinforcing rib 530 connected to the inner side of the first U-shaped clamp 510 and the inner side of the second U-shaped clamp 520, and a locking piece 540 for fixing the reinforcing rib 530 and the first U-shaped clamp 510 / the second U-shaped clamp 520, and the positioning ear 521 and the first U-shaped clamp 510. When installing, the first U-shaped clamp 510 and the second U-shaped clamp 520 can be respectively sleeved. It is arranged on the outer side of the corresponding support columns 200 on both sides, and then the distance between the two U-shaped clamps is reduced until the positioning ear 521 is connected to the end of the first U-shaped clamp 510, and then the two U-shaped clamps are fixedly connected to the metal pipe sleeve 210, and then the ends of the first U-shaped clamp 510 and the second U-shaped clamp 520 are connected and fixed by the locking piece 540 and the positioning ear 521, and then the reinforcing rib 530 is placed on the inner side of the first U-shaped clamp 510 and the second U-shaped clamp 520, and the U-shaped clamp is connected and strengthened by the locking piece 540. In this way, the upper, lower ends and middle parts of the two support columns 200 are firmly connected as a whole, thereby improving the balanced force and support stability of the support structure.

[0025] The upper and lower ends of the support column 200 are both metal-sheathed. During installation, the upper and lower ends of the support column 200 can be directly inserted into the corresponding positioning sleeves 700 in the base 100 and the top plate 300, and a reinforced connection can be formed by the inserted ribs 710. It should be noted that after the actual installation is completed, the end of the support column 200 can be hot-melt welded to the positioning sleeve 700 and the inserted ribs 710 by resistance welding, so that a fixed integrated structure is formed between the support column 200, the base 100 and the top plate 300, so that the force on the support structure is more balanced, the destructive interference caused by the lateral shear prestress is reduced, and the support application is more stable.

[0026] Furthermore, a plurality of ZFC-type shock absorbers 600 for supporting and connecting the mounting pad 400 are provided on the top of the top plate 300. Here, by adopting the ZFC-type shock absorbers 600 specially used for bridges, a certain buffering stress and deformation avoidance force are formed between the upper end of the supporting structure and the main body of the bridge, which can reduce the adverse vibration brought to the supporting structure by the bridge during use, thereby further improving the use effect and overall stability of the supporting structure.

[0027] Furthermore, a plurality of positioning connectors 410 that are docked with the bottom of the bridge frame are also provided on the top of the mounting pad 400. It can be understood that the mounting pad 400 is used to overlap the load-bearing bridge body, and the positioning connectors 410 can be positioned and connected with the connector at the bottom of the bridge frame when installed between the two, so as to form a stable installation between the supporting structure and the bridge.

[0028] In summary, in a bridge reinforcement support structure of the present embodiment, during installation, the upper and lower ends of the support column 200 are inserted into the corresponding positioning base sleeves 700 in the base 100 and the top plate 300 by means of hoisting, and a reinforced connection is formed by means of dowel rods 710, and the ends of the support column 200 are hot-melt welded to the positioning base sleeves 700 and the dowel rods 710 by means of resistance welding, so that a fixed integrated structure is formed between the support column 200, the base 100 and the top plate 300, and then the reinforcing hoop sleeves 500 of multiple units can be connected and installed on the two support columns 200 respectively, and the bridge frame at the uppermost end is finally docked and placed on the installation pad 400, so that the entire support structure forms a firm longitudinal plate valve force-bearing structure, which effectively avoids the disadvantages of the existing support structure such as foundation settlement deviation caused by prestressed force interference, and difficulty in ensuring the stability and use effect of the support structure.
