Description

Technical Field

[0001] This application relates to the field of bridge construction technology, and in particular to an adjustable rebar tying frame for the bottom web of a small box girder. Background Technology

[0002] In bridge construction, precast small box girders have become a standardized construction method. Precast small box girders require the bottom and web reinforcement bars to be tied before being hoisted into the casting formwork. During the bottom and web reinforcement tying process, a reinforcement tying frame is needed. However, currently, traditional bottom and web reinforcement tying frames are typically only suitable for tying the bottom and web reinforcement bars of a single-specification small box girder.

[0003] For example, the utility model patent with announcement number CN206186089U discloses a rebar tying frame for box girders. It uses bottom rods to position the bottom rebar cage, side rods to position the side rebar cages, and horizontal frames to position the longitudinal rebars. However, the dimensions of its structure cannot be adjusted. When dealing with precast small box girders of different specifications, such as changes in parameters like the width of the bottom plate, the inclination of the web, and the height of the precast small box girder, the width of the bottom rebar cage, the inclination of the side rebar cages, and the spacing of the longitudinal rebars all need to be adjusted accordingly. The tying frame disclosed in this patent will not be applicable. Therefore, a rebar tying frame with a wider range of applications is needed. Utility Model Content

[0004] Based on this, it is necessary to provide an adjustable rebar tying frame for the bottom web of a small box girder, and the specific technical solution is as follows.

[0030] Embodiment

[0031] Reference Figure 1As shown, this embodiment provides an adjustable rebar tying frame for the bottom web of a small box girder, which includes a base 1, side supports 2, and positioning pins 3. The base 1 includes bottom horizontal bars 11 and bottom vertical bars 12. Multiple bottom horizontal bars 11 are arranged longitudinally, and two bottom vertical bars 12 are welded to each bottom horizontal bar 11 in sequence. The bottom vertical bars 12 are provided with first positioning slots 13, which are used to longitudinally position and support the bottom rebar cage. Since the first positioning slots 13 have a certain depth, they can also prevent the bottom rebar cage from tilting. The side supports 2 include first diagonal braces 21, second diagonal braces 22, and side vertical bars 23. Multiple first diagonal braces 21 are arranged longitudinally, and the first diagonal braces 21 are arranged in a one-to-one correspondence with the bottom horizontal bars 11. One end of the first diagonal brace 21 is hinged to the bottom crossbar 11, and the other end is hinged to one end of the second diagonal brace 22. An angle adjustment component 25 is installed between the first diagonal brace 21 and the second diagonal brace 22. Two side longitudinal bars 23 are sequentially connected to multiple first diagonal braces 21, and the side longitudinal bars 23 are provided with second positioning slots 24, which are used to position the side reinforcement cage longitudinally and inclination. By adjusting the angle between the first diagonal brace 21 and the second diagonal brace 22, the inclination of the first diagonal brace 21 can be adjusted, thereby adapting to side reinforcement cages with different inclinations. The positioning pin 3 includes multiple pin pieces and telescopic components. The pin pieces are used to support the longitudinal reinforcement. Multiple pin pieces are arranged vertically, and adjacent pin pieces are connected by telescopic components. In this embodiment, the number of pin pieces can be set to be two more than the number of longitudinal reinforcements to be supported, and two pin pieces are used to be movably connected to the side support 2.

[0032] The adjustable rebar tying frame for the bottom web of a small box girder provided in this embodiment can adapt to side rebar cages with different inclinations by changing the angles of the first diagonal brace 21 and the second diagonal brace 22. By reducing the inclination of the first diagonal brace 21, interference of the side longitudinal bar 23 with the bottom rebar cage of a larger size can be avoided during hoisting, thus adapting to bottom rebar cages of different sizes. By changing the height of different inserts, it can adapt to longitudinal rebars with different spacings. Therefore, this rebar tying frame can adapt to small box girders of different specifications and has a wide range of applications.

[0033] Specifically, refer to Figure 2 As shown, the insert includes a horizontal bar 31 and a vertical bar 32, which are connected to form a T-shaped structure. The telescopic member includes a first sleeve 33, with internal threads of opposite directions at both ends, and both ends of the first sleeve 33 are threadedly connected to the vertical bars 32 of two adjacent inserts. By rotating the first sleeve 33, the spacing between adjacent horizontal bars 31 can be adjusted to accommodate longitudinal reinforcing bars with different spacings. To facilitate adjustment of the first sleeve 33, a wrench bar perpendicular to the first sleeve 33 is welded to it.

[0034] Specifically, the first diagonal brace 21 and the second diagonal brace 22 are arranged symmetrically. The first diagonal brace 21 is provided with two first insertion sleeves 34, and the second diagonal brace 22 is provided with two second insertion sleeves 35. The first insertion sleeves 34 and the second insertion sleeves 35 are arranged at the same height, and the crossbar 31 is inserted into the first insertion sleeves 34 and the second insertion sleeves 35 in sequence. The first insertion sleeve 34 is connected to a first rotating shaft, and the first diagonal brace 21 is provided with a first mounting hole, in which the first rotating shaft is rotatably inserted. The second insertion sleeve 35 is connected to a second rotating shaft, and the second diagonal brace 22 is provided with a second mounting hole, in which the second rotating shaft is rotatably inserted. When the inclination of the first diagonal brace 21 is changed, the first insertion sleeves 34 and the second insertion sleeves 35 can be rotated to keep their axial direction horizontal, thereby facilitating the insertion of the crossbar 31.

[0035] Specifically, the angle adjustment assembly 25 includes a first connecting rod 26, a second connecting rod 27, and a second sleeve 28. The first connecting rod 26 is hinged to the first diagonal brace 21, and the second connecting rod 27 is hinged to the second diagonal brace 22. The two ends of the second sleeve 28 are respectively provided with internal threads in opposite directions, and the second sleeve 28 is threadedly connected to the first connecting rod 26 and the second connecting rod 27. By rotating the second sleeve 28, the distance between the first connecting rod 26 and the second connecting rod 27 is adjusted, thereby adjusting the distance between the first diagonal brace 21 and the second diagonal brace 22, and changing the inclination of the first diagonal brace 21.

[0036] Work process: Adjust the size and spacing of the rebar tying frame according to the tying specifications of the bottom web rebar of the small box girder, and tie the corresponding bottom rebar cage, side rebar cage, and longitudinal rebar. Refer to the following for the final state after tying. Figure 3 As shown. Then, pull out the positioning pin 3 and adjust the tilt angle of the first diagonal brace 21 until it no longer affects the hoisting of the longitudinal reinforcement and the bottom reinforcement cage. Finally, hoist the tied reinforcement, and its state is as shown. Figure 4 As shown.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
