Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing tools, in particular to a stirrup bending tool. Background Art

[0002] Steel cage is a commonly used steel structure in the columns, beams and other components of building structures. Most steel cages include main bars and stirrups. Multiple main bars are arranged along the inner edge of the component, and stirrups surround the outer side of the multiple main bars. Multiple stirrups are arranged along the axial direction of the main bars to form an overall steel cage structure. At present, the cross-sectional shape of the component includes rectangular, circular or other special-shaped structures. The shape of the stirrup is determined according to the cross-sectional shape of the component. During the steel engineering operation, the long straight steel bars need to be bent multiple times according to the cross-sectional shape of the component to form a ring-shaped stirrup that meets the requirements.

[0003] Although the steel bar bending equipment in the prior art can bend the steel bars efficiently and accurately, the processed stirrups are in an annular structure, which is inconvenient to install and connect with the long straight main bars, especially when encountering a small ring beam (lintel) at the construction site, the finished stirrups cannot be used. Chinese utility model patent CN212129956U discloses a steel bar binding tool, including a fuselage, a head, a drive assembly and a fixed handle. There is a receiving space in the fuselage, and the drive assembly is accommodated in the receiving space. The head is an elbow structure, one end of which extends from the head of the fuselage to drive its self-rotation through the drive assembly, and the other end of the head is provided with a circular hole for inserting the wire. Although the steel bar binding tool can bend the steel bar during the steel bar binding process, it is necessary to insert the steel bar into the circular hole. The depth of the circular hole is limited, and it is impossible to achieve accurate bending control of multiple required bending parts on the stirrup, which affects the steel bar processing quality. Therefore, it is necessary to provide a stirrup bending tool that can solve the problem of poor bending quality of the stirrups by the binding tool in the prior art. Summary of the invention

[0004] The utility model aims to provide a stirrup bending tool, which can solve the problem of poor bending quality of stirrups by binding tools in the prior art.

[0005] The utility model is achieved in this way:

[0006] A stirrup bending tool comprises a wrench and a main reinforcement sleeve; the main reinforcement sleeve is a hollow cylindrical structure with an opening on one side, and the main reinforcement sleeve can be coaxially sleeved on the main reinforcement through the opening; stirrup grooves with U-shaped structures are formed at the edges of both sides of the opening, the stirrups are wound around the main reinforcement, so that the stirrups pass through the two stirrup grooves, and the stirrups can abut against the end of the stirrup groove away from the opening; the wrench is a long strip structure, and one end of the wrench is fixedly connected to the other side of the main reinforcement sleeve away from the opening.

[0007] The edges of both sides of the opening are formed with avoidance expansion openings, which are connected with the opening and the stirrup groove.

[0008] The width of the avoidance expansion opening is greater than the width of the stirrup groove.

[0009] The width of the stirrup groove is greater than the diameter of the stirrup.

[0010] The axial direction of the wrench, the length direction of the stirrup groove and the radial extension line passing through the center of the main reinforcement sleeve are located in the same plane.

[0011] The width of the opening is greater than the diameter of the main reinforcement, and the opening is continuous with the main reinforcement sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a main reinforcement sleeve, and a stirrup groove is arranged on the main reinforcement sleeve, which can be used to clamp and limit the stirrup, and the end of the stirrup groove pushes the stirrup to rotate and bend it to a specified angle, thereby ensuring that the bending quality of each bending part of the stirrup meets the design requirements; at the same time, the avoidance expansion is set to avoid other structural parts at the connection part between the main reinforcement and the stirrup, and it can adapt to stirrups with larger diameters, which is convenient for the bending processing of the stirrup.

[0014] 2. Since the utility model is provided with a wrench, the longer wrench can easily drive the main reinforcement sleeve to rotate relative to the main reinforcement, thereby pushing the bending part of the stirrup through the stirrup groove, and making the stirrup rotate along the bending part to bend to any desired angle, making the bending process of the stirrup more time-saving and labor-saving, which is conducive to improving the efficiency and quality of the stirrup bending process.

[0015] 3. The utility model is easy to obtain materials and manufacture, has low manufacturing cost, simple structure, and is easy to use. It can meet the bending processing of stirrups on construction sites, has a wide range of applications, and a high turnover rate. It can especially solve the problem of difficult bending of stirrups in small ring beams (lintels). BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Please see attached Figure 1 To Attachment Figure 3 A stirrup bending tool comprises a wrench 1 and a main reinforcement sleeve 2; the main reinforcement sleeve 2 is a hollow cylindrical structure with an opening on one side, and the main reinforcement sleeve 2 can be coaxially sleeved on the main reinforcement 3 through the opening; stirrup grooves 201 of U-shaped structure are formed at the edges of both sides of the opening, and the stirrup 4 is wound around the main reinforcement 3, so that the stirrup 4 passes through the two stirrup grooves 201, and the stirrup 4 can abut against the end of the stirrup groove 201 away from the opening; the wrench 1 is a long strip structure, and one end of the wrench 1 is fixedly connected to the other side of the main reinforcement sleeve 2 away from the opening.

[0022] Preferably, the wrench 1 can be made of steel bars, and the length of the wrench 1 can be adaptively adjusted according to actual use requirements. The length of the wrench 1 can be longer to facilitate force application, and the lever principle can be used to make the entire bending process of the stirrup 4 more labor-saving.

[0023] Preferably, the main reinforcement sleeve 2 can be made of a round steel pipe with a specification larger than the diameter of the main reinforcement 3, and an opening is cut on one side of the main reinforcement sleeve 2. The wrench 1 is welded and fixed to the main reinforcement sleeve 2, which makes it easy to sleeve the main reinforcement sleeve 2 on the main reinforcement 3 and rotate relative to the main reinforcement 3 driven by the wrench 1.

[0024] The stirrup groove 201 can be cut and formed at the opening side edge of the main reinforcement sleeve 2 according to the diameter of the stirrup 4. The U-shaped stirrup groove 201 can be used to provide three-way limiting for the stirrup 4, so that when the wrench 1 is rotated, the end of the stirrup groove 201 away from the opening can push the bending part of the stirrup 4, so that the bending part of the stirrup 4 is rotated a certain angle in the specified direction, thereby completing the bending process of the stirrup 4.

[0025] Please see attached Figure 1 The edges of both sides of the opening are formed with avoidance expansion openings 202 , and the avoidance expansion openings 202 are connected to the opening and the stirrup groove 201 .

[0026] By setting the avoidance expansion opening 202 , objects such as iron wires that may exist on both sides of the stirrup 4 can be avoided, thereby avoiding affecting the rotation of the main reinforcement sleeve 2 .

[0027] Please see attached Figure 1 The width of the avoidance expansion 202 is greater than the width of the stirrup groove 201.

[0028] The avoidance expansion opening 202 with a larger width can not only play an effective avoidance effect, but also be used to clamp the stirrup 4 whose limiting diameter is larger than the width of the stirrup groove 201, so it is suitable for bending stirrups 4 of various sizes.

[0029] Please see attached Figure 1 The width of the stirrup groove 201 is slightly larger than the diameter of the stirrup 4.

[0030] The diameter of the conventional stirrup 4 is 6 mm. Preferably, the width of the stirrup groove 201 can be 7-8 mm to ensure that the stirrup 4 is limited in the stirrup groove 201 and avoid tilting during the rotation and bending process to affect the quality of the steel bar project.

[0031] Please see attached Figure 1 The axial direction of the wrench 1, the length direction of the stirrup groove 201 and the radial extension line passing through the center of the main reinforcement sleeve 2 are located in the same plane.

[0032] When the wrench 1 is rotated, the force direction is located in the plane, thereby ensuring the stability during the steel bar bending operation and avoiding bending damage of the tool after being stressed.

[0033] Please see attached Figure 1 The width of the opening is slightly larger than the diameter of the main reinforcement 3, and the opening is connected to the main reinforcement sleeve 2 in a continuous manner, so that the main reinforcement sleeve 2 can be coaxially sleeved on the main reinforcement 3 through the opening.

[0034] Please see attached Figure 1 To Attachment Figure 3 , the usage method and working principle of the utility model are:

[0035] Taking a steel cage with a rectangular cross-section as an example, after the four main bars 3 are positioned, the stirrups 4 are placed on the outside of the main bars 3 and arranged perpendicularly to the main bars 3 .

[0036] The main reinforcement sleeve 2 is coaxially sleeved on the main reinforcement 3 through the opening, and the stirrups 4 pass through the main reinforcement sleeve 2 through the stirrup grooves 201 on both sides of the opening, and the parts of the stirrups 4 that need to be bent are abutted against the ends of the corresponding stirrup grooves 201.

[0037] The wrench 1 is rotated along the bending direction of the stirrup 4, and the main reinforcement sleeve 2 is rotated relative to the main reinforcement 3, so that the end of the stirrup groove 201 pushes the stirrup 4 to rotate in the required bending direction until the stirrup 4 is bent to a specified angle, and the wrench 1 is stopped to complete one bending of the stirrup 4.

[0038] Repeatedly turn the wrench 1 to bend the three bending parts of the stirrup 4 by 90° along the arrangement positions of the three main bars 3. Then bend the two ends of the stirrup 4 by 135° in the same way to form a rectangular ring-shaped stirrup 4, and form a limited connection with the main bar 3 through the end bent by 135° to avoid displacement of the stirrup 4, thus completing the bending process of the stirrup 4, and then the steel bar binding and fixing operation can be carried out.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
