Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bridge construction, and in particular to a bridge fastening and correction tool. Background Art
[0002] With the development and progress of the country, the infrastructure construction of roads, railways, etc. is increasing. In the construction of large-span cast-in-place bridges, cranes are usually used to lift prefabricated piers and transport them to the top of the pier cap. When the prefabricated piers are in a static state, the prefabricated piers are placed in the pier cap, and then the subsequent bridge erection operations are carried out under the prefabricated piers. However, the prefabricated piers cannot be in the same axis when placed on the pier cap.
[0003] In the prior art, a tripod and a semicircular flange are usually used to clamp and calibrate the prefabricated bridge piers. However, the installation of the clamp, the locking and removal of the bolts, and the setting of the tripod often require at least two construction workers to work together. When the bridge has a large drop and span, the clamp is heavy and the workers need to work in mid-air, which makes the construction difficult and causes major accidents. Although safety ropes can be worn for protection, the construction progress will be affected by the environmental and weather factors of the construction site, which will increase the construction cost.
[0004] Therefore, there is an urgent need for a bridge tightening and correction tool to solve the above problems. Utility Model Content
[0005] The embodiment of the present application provides a bridge tightening and correction tool, aiming to improve the correction efficiency of bridge piers while ensuring the safety of the working environment.

[0012] Furthermore, a clamping assembly is arranged at the connection between the first hoop and the second hoop;
[0013] The clamping assembly includes: a first bolt, a nut, and a second bolt;
[0014] The first bolt is vertically arranged at one end of the second hoop close to the first hoop, and the root of the first bolt passes through the cross plate and abuts against the outer end surface of the first hoop, capable of driving the first hoop to approach or move away from the prefabricated component;
[0015] The nut is fixedly arranged on the end surface of the first rib plate away from the second hoop;
[0016] The head of the second bolt abuts against the end surface of the second rib plate away from the first hoop.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.
[0031] Combined with Figure 1 - Figure 2 As shown, a bridge fastening and correcting tool includes: a base 1, a first stirrup, a second stirrup, and a lifting member 30; the base 1 is horizontally arranged on the ground, and a plurality of first hoops 10 and second hoops 20 are arranged above the base 1. A second hoop 20 is fixedly connected between adjacent first hoops 10. There is a gap at the connection of the first hoop 10 and the second hoop 20. The area surrounded by the first hoop 10 and the second hoop 20 is adapted to the shape of the precast member 2. A plurality of lifting members 30 are placed on the base 1, and the output ends of the lifting members 30 respectively abut against the sides of the first hoop 10 and the second hoop 20, and can move away from or close to the tabletop of the base 1.
[0032] It should be noted that the overall shape of the precast bridge pier in this application is Y-shaped, its bottom end is rectangular, and its adjacent side edges are arc-transitioned. When the precast bridge pier reaches the installation base 1, the bottom end of the precast bridge pier needs to solidify with the slurry of the installation base 1 to form an integral body. The bridge fastening and correcting tool of this application is composed of a first hoop 10, a second hoop 20, and a lifting member 30. A second hoop 20 is fixedly connected between adjacent first hoops 10 to form an enclosing area for restraining the precast bridge pier, and the gap at the connection of the first hoop 10 and the second hoop 20 can share the stress generated when the bottom of the precast bridge pier solidifies with the installation base 1 to form an integral body. The output end of the lifting member 30 abuts against the sides of the first hoop 10 and the second hoop 20 to lift the relative positions of the first hoop 10 and the second hoop 20 around the precast bridge pier, and then clamp the bottom of the precast bridge pier.
[0033] The top of the first hoop 10 extends horizontally outwards to form a first ear plate 11, and a plurality of first rib plates 12 are uniformly arranged on the lower end surface of the first ear plate 11; the top of the second hoop 20 extends horizontally outwards to form a second ear plate 21, and a plurality of second rib plates 22 are uniformly arranged on the lower end surface of the second ear plate 21. On the outer end surface of the second ear plate 22 near the two ends of the first hoop 10 of the second hoop 20, a cross plate 23 is fixedly arranged. The front plate surface of the cross plate 23 is perpendicular to the front plate surface of the second ear plate 21 and parallel to the front plate surface of the first ear plate 11. The arrangements of the first ear plate 11 and the second ear plate 21 are to enhance the modal strength of the first hoop 10 and the second hoop 20 to ensure the structural stability of the first hoop 10 and the second hoop 20. In this application, the first ear plate 11 and the second ear plate 21 can be an integral structure with the first hoop 10 and the second hoop 20, or they can be a split structure. The first and second ear plates are respectively welded to the tops of the first and second hoops by welding, and then the output end of the lifting member 30 abuts against the sides of the first hoop 10 and the second hoop 20, so as to facilitate the lifting member 30 to lift or lower the first hoop 10 and the second hoop 20.
[0034] Furthermore, a clamping assembly is arranged at the connection between the first hoop 10 and the second hoop 20; the clamping assembly includes: a first bolt 50, a nut 51, and a second bolt 52; the first bolt 50 is vertically arranged at one end of the second hoop 20 close to the first hoop 10, and the root of the first bolt 50 passes through the cross plate and abuts against the outer end surface of the first hoop 10, and can drive the first hoop 10 to approach or move away from the prefabricated part 2; the nut 51 is fixedly arranged on the end surface of the first rib plate 12 away from the second hoop 20; the head of the second bolt 52 abuts against the end surface of the second rib plate 22 away from the first hoop 10, and the root of the second bolt 52 passes through the second rib plate 22, the first rib plate 12 and is screwed with the nut 51, and can drive the second hoop 20 to approach or move away from the first hoop 10.
[0035] In the above solution, the purpose of setting the clamping assembly at the connection between the first hoop 10 and the second hoop 20 is to facilitate the adjustment of the relative positions of the first hoop 10 and the second hoop 20. The staff can manually rotate or use tools to initially rotate the first bolt 50. The root of the first bolt 50 abuts against the end face of the first hoop 10, and the first hoop 10 is abutted against the outer wall of the prefabricated member 2. Then, manually or using tools, rotate the second bolt 52, and displace the second hoop 20 constrained by the head of the second bolt 52 towards the first hoop 10 to adjust the surrounding area formed after the first hoop 10 and the second hoop 20 are connected to each other, so that the inner end faces of the first hoop 10 and the second hoop 20 are in close contact with the outer wall surface of the prefabricated member 2. When the lifting member lifts the first hoop 10 and the second hoop 20 to make them abut against the outer wall of the prefabricated member 2, the staff can manually or mechanically rotate the first bolt 50 and the second bolt 52 to adjust the gap size at the connection between the first hoop 10 and the second hoop 20, thereby ensuring the connection stability between the first hoop 10, the second hoop 20 and the prefabricated member 2.
[0036] The output end of the lifting member 30 abuts against the lower end faces of the first ear plate 11 and the second ear plate 21, and the output ends of the lifting member 30 are respectively arranged between the adjacent first rib plates 12 and the adjacent second rib plates 22.
[0037] The lifting member 30 in this application can be a jack or a telescopic cylinder. Its purpose is to displace the first hoop 10 and the second hoop 20 on the outer wall of the precast pier by the output end of the lifting member 30, so as to complete the clamping operation of the first hoop 10 and the second hoop 20 on the precast pier. In addition, since the bottom of the precast pier has been in a clamped and constrained state, during the process of the first hoop 10 and the second hoop 20 being pushed by the lifting member 30, the precast pier can have a calibration displacement with the installation base 1 to ensure that the precast pier can be coaxial with the installation base 1.
[0038] Both ends of the second rib plate 22 are in a curved structure, and the inner wall of the curved structure can fit on the outer wall of the flank of the prefabricated member 2. The purpose of such a setting is not only to protect the outer wall of the flank of the prefabricated member 2 (the flank wall surface of the precast pier), but also to share the stress at the stress-weak part of the precast pier.
[0039] Anti-slip pads 40 are pasted on the inner walls of the first hoop 10 and the second hoop 20 shown, and the material of the anti-slip pads 40 is polyurethane. In the above solution, on the one hand, the setting of the anti-slip pads 40 can prevent the outer wall of the prefabricated member 2 from being scratched when the first hoop 10 and the second hoop 20 move relative to the wall surface of the prefabricated member 2, so as to ensure the surface integrity of the outer wall of the prefabricated member 2; on the other hand, it can prevent the first hoop 10 and the second hoop 20 from slipping relative to the prefabricated member 2, so as to ensure the stable contact among the three.
[0040] The gasket edge of the anti-slip gasket 40 is flush with the hoop edges of the first hoop 10 and the second hoop 20. This setting aims to make the appearance of the first hoop 10 and the second hoop 20 more aesthetically pleasing. On the other hand, it is to prevent the anti-slip gasket 40 from curling when the lifting member 30 lifts the first hoop 10 and the second hoop 20 to move on the outer wall of the precast member 2 and make an interference fit, thereby ensuring that the lifting member 30 can stably lift the first hoop 10 and the second hoop 20.
[0041] Multiple lifting members 30 are provided, and the feed rates of the output ends of the respective lifting members 30 are always at the same frequency. Providing multiple lifting members 30 can ensure stable support for the respective first hoops 10 and second hoops 20. Moreover, the feed rates of the output ends of the lifting members 30 being at the same frequency not only prevents the first hoop 10 and the second hoop 20 from shearing and damaging the peripheral surface of the bottom of the precast bridge pier due to different feed rates of the output ends of the lifting members 30, but also enables the precast bridge pier and the installation base 1 to always be in the same axis, facilitating subsequent operations of the precast bridge pier.
[0042] This application does not limit the shapes of the first hoop 10 and the second hoop 20, which can be strip-shaped or cylindrical. To highlight the advantages of the bridge fastening and alignment tool in this application, the first hoop 10 and the second hoop 20 are strip-shaped, which can fit well with the peripheral surface of the bottom of the precast bridge pier to achieve the purpose of clamping. The staff first combines the first hoop 10 and the second hoop 20 into two halves, respectively enclosing the periphery of the precast member 2, and then uses methods such as screwing and clamping to lock them, so that the first hoop 10 and the second hoop 20 can fit on the peripheral surface of the precast member 2.
[0043] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.
[0044] The above embodiments are only used to illustrate the technical solutions of this application, rather than limiting this application; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of this application.
