Description

Technical Field

[0001] This utility model belongs to the field of municipal and highway bridge construction technology, specifically relating to a small box girder mesh steel reinforcement module and assembly. Background Technology

[0002] In the construction of precast small box girder steel reinforcement cages for municipal and highway projects, traditional methods mainly rely on manual operation, including CNC bending machines for steel bar cutting and processing, and the use of jigs for steel bar binding and installation. These traditional processes have several drawbacks, such as discrepancies between jig processing accuracy and design drawings, uneven straightening of longitudinal reinforcement bars, and straightening issues during the binding process. Completing the steel reinforcement cage binding of a small box girder requires a large number of workers to work continuously for extended periods, resulting in high labor costs and low production efficiency.

The module body is a mesh structure with a concave shape and an open top in the transverse cross section. The mesh structure is formed by bending a planar mesh of a certain length. The planar mesh is composed of transversely arranged transverse steel bars and longitudinally arranged longitudinal steel bars interlaced with each other. One end of the longitudinal steel bar is provided with a first connector and the other end is provided with a second connector.

[0006] As described in the small box girder mesh reinforcement module, the transverse cross-section of the mesh structure is "U" shaped or inverted trapezoidal.

[0007] On the other hand, an assembly is provided, wherein the small box girder mesh steel reinforcement modules as described above are sequentially connected by a third connector, wherein the third connector is respectively connected to the first connector and the second connector.

[0008] As described in the assembly, the third connecting member includes a connecting sleeve and a locking nut, the connecting sleeve has an internal thread, the end of the longitudinal reinforcing bar has an external thread, and both the first connecting member and the second connecting member are sleeves with internal and external threads.

[0009] As described in the assembly, the first connector is a short double-threaded sleeve, and the second connector is a long double-threaded sleeve.

[0010] The beneficial effects of this utility model's technical solution are:

[0011] This invention can be manufactured using automated processing equipment. Multiple modules can be quickly mechanically connected and assembled using connecting sleeves and locking nuts, reducing the fabrication time of the rebar cage, lowering the labor intensity of workers, and significantly improving production efficiency.

[0018] The terms “utility model” and “this utility model” used in this specification are intended to broadly refer to all subject matter of this specification and any of the following patent claims. Statements containing these terms should not be construed as limiting the subject matter described herein or limiting the meaning or scope of any of the following patent claims. Furthermore, this specification does not attempt to describe or limit the subject matter covered by any claim of any particular component, paragraph, statement, or drawing of this application.

This utility model may have other embodiments and be practiced or implemented in other ways. Moreover, it should be understood that the wording and terminology used herein are for illustrative purposes and should not be considered limiting.

[0019] The details of the present invention will now be discussed with reference to the accompanying drawings, which are illustrated by way of example only. In the drawings, similar features or components may be labeled with the same reference numerals.

While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0021] See Figure 1 , Figure 2 As shown, the small box girder mesh reinforcement module of this utility model includes a module body located on the outside of the bottom web of the small box girder. The module body is a mesh structure with a concave shape and an open top in the transverse cross section. The mesh structure is formed by bending a planar mesh of a certain length. The planar mesh is composed of transversely arranged transverse steel bars 1 and longitudinally arranged longitudinal steel bars 2 interlaced with each other. One end of the longitudinal steel bar 2 is provided with a first connector and the other end is provided with a second connector.

[0022] Furthermore, the transverse cross-section of the mesh structure is U-shaped or inverted trapezoidal.

[0023] The forming of the steel reinforcement modules involves using an automated wire mesh welding machine to process the longitudinal and transverse steel reinforcements of the outer layer of the bottom web of the small box girder into flat mesh sheets of a certain length, and then using an automated wire mesh bending machine to bend the flat mesh sheets into "U" or inverted trapezoidal mesh structure segments.

[0024] This utility model also relates to an assembly component, see below. Figure 3 , Figure 4 As shown, the assembly is formed by connecting small box girder mesh steel reinforcement modules sequentially through a third connector, which connects the first connector and the second connector respectively.

[0025] Referring to the diagram, the third connector includes a connecting sleeve 3 and a locking nut 4. The connecting sleeve 3 has an internal thread, and the end of the longitudinal steel bar 2 has an external thread. Both the first and second connectors are sleeves with internal and external threads.

[0026] Furthermore, the first connecting member is a double-threaded short sleeve 5, and the second connecting member is a double-threaded long sleeve 6.

[0027] Each longitudinal steel bar 2 of each steel bar module has external threads processed at one end (beam end module) or both ends (mid-span module), and the external threads of the longitudinal steel bars 2 connected to adjacent steel bar modules are reverse threads. One longitudinal steel bar 2 is equipped with a double-threaded short sleeve 5, and the other longitudinal steel bar 2 is equipped with a double-threaded long sleeve 6. Both the double-threaded short sleeve 5 and the double-threaded long sleeve 6 are machined with internal threads and external threads. The internal threads are used to connect with the longitudinal steel bar 2, and the external threads are used to connect with the connecting sleeve 3.

[0028] When assembling the mesh-like steel reinforcement modules of the small box girder, first screw the locking nut 4 onto the longitudinal steel bar 2 at one end of one of the steel reinforcement modules. Then, screw the internal thread of the double-threaded long sleeve 6 onto the external thread of the longitudinal steel bar 2 at the same end. Screw the internal thread of the double-threaded short sleeve 5 onto the external thread of the longitudinal steel bar 2 of the other steel reinforcement module. Continue to screw the connecting sleeve 3 into the external thread of the double-threaded long sleeve 6. Then, rotate the connecting sleeve 3 towards the double-threaded short sleeve 5 to complete the connection with the double-threaded short sleeve 5. Finally, tighten the locking nut 4 to complete the assembly of the mesh-like steel reinforcement modules of the adjacent small box girder.

[0029] This invention can be manufactured using automated processing equipment. Multiple modules can be quickly mechanically connected and assembled using connecting sleeves and locking nuts, reducing the fabrication time of the rebar cage, lowering the labor intensity of workers, and significantly improving production efficiency. It has good economic and social benefits and is worthy of widespread application.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
