Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an on-site stirrup bending device. Background Technology

[0002] The construction industry is developing rapidly, and the infrastructure construction sector is not to be underestimated. A large number of engineering facilities and energy facilities are being implemented simultaneously, and large-scale steel reinforcement installation and processing are emerging one after another. High-rise and super high-rise structures are being built one after another, usually using reinforced concrete structures.

[0003] During on-site construction, beams and columns are reinforced with main reinforcement bars and stirrups to enhance structural strength. Main reinforcement bars are longitudinally arranged steel bars within the beam, while stirrups are transversely arranged steel bars. They are also connected by hooks between multiple layers of reinforcement bars or between the inner and outer sides of the beam. On-site construction often results in the omission of stirrups or the addition of extra hooks, leading to rework. A common practice is to manually bend the stirrups for installation and then restore them to their original shape, resulting in repeated bending of the stirrups. This repeated bending can easily cause quality defects and poses certain safety risks. Conversely, if the stirrups are manually forcibly opened and then restored, it is difficult to restore them to their original structural shape, making precise installation impossible.

[0004] Therefore, this patent application is filed. Utility Model Content

[0031] During the construction of beams and columns, it is inevitable that stirrups or tie hooks will be missed. In these cases, manual bending is used to force them to be installed and then they are restored to their original state. This practice has the following disadvantages:

[0032] Disadvantage 1: Existing technology forces the stirrups to be opened during installation, which can easily cause repeated bending of the bent parts, creating potential quality problems;

[0033] Disadvantage 2: For some large-scale structures, it is impossible to add stirrups, or to cut a stirrup into multiple sizes and assemble them on site, which cannot form an overall load-bearing structure, resulting in significant material damage and low construction efficiency;

[0034] Disadvantage 3: Manually forcibly prying open the stirrups and then restoring them makes it difficult to restore them to their original structural shape, making precise installation impossible.

[0035] To address the above problems, this utility model provides an on-site stirrup bending device, which will be explained in detail through specific embodiments.

[0036] Example 1:

[0037] like Figures 1-3 As shown, this embodiment provides a field stirrup bending device, which includes a bending body 1 and a handle 2. The bending body 1, as the main part of the device, is used to accommodate the main reinforcing bar 8 and apply force to the stirrup 9 for bending. The handle 2 serves as a hand grip and is fixedly connected to the side of the bending body 1. A slot 3 adapted to the size of the main reinforcing bar 8 is provided on the bending body 1, allowing the main reinforcing bar 8 to enter into the slot 3, satisfying the bending of stirrup 9 with a diameter of φ4-φ12mm. An opening 4 is also provided on the bending body 1, which starts from one end of the bending body 1 and extends along the bending body 1 to its other end. The opening 4 communicates with the slot 3, allowing the stirrup 9 perpendicular to the main reinforcing bar 8 to enter into this opening 4, thereby securing the stirrup 9 between the main reinforcing bar 8 and the bending plate before bending, in preparation for bending.

[0038] The working principle of the stirrup bending device in this embodiment is as follows:

[0039] The construction worker holds the bending device and moves it from one side of the stirrup 9 towards the stirrup 9, allowing the stirrup 9 to enter through the opening 4. Simultaneously, the worker moves it upwards so that the main reinforcement 8, perpendicular to the stirrup 9, is inserted into the slot 3. Thus, the stirrup 9 is held between the main reinforcement 8 and the bending device. Figure 4 The diagram shows the state of the stirrup 9 being held between the main reinforcement 8 and the device of this embodiment.

[0040] Once secured, as Figure 5 In the first step, rotate the handle 290° to form the state of the second step; then bend the opposite stirrups 9. Using the same method as above, in the third step, first fix the bending device, and then perform the fourth step of bending so that the stirrups 9 on both sides are bent by 90°.

[0041] The stirrup 9 bending device provided in this embodiment can be manufactured using conventional steel pipes and reinforcing bars, and can meet the bending requirements of φ4-φ12mm reinforcing bars. All materials used are conventional, the structure is simple, and the processing is convenient. It can be factory-produced or processed on-site, greatly reducing construction technical difficulty and rework costs, and improving efficiency. Furthermore, this device uses the lever principle to bend and twist the reinforcing bars to be bent on-site, solving the problem of on-site bending accuracy. It can quickly and effectively achieve the bending target and requirements, smoothly completing the addition of stirrup 9 and hooks, ensuring construction quality, and reducing safety hazards.

[0042] Furthermore, in this embodiment, the bent body 1 is designed as a plate structure. Even better, it is designed as an arc-shaped plate structure, with the slot 3 being an arc-shaped through groove, forming a U-shaped slot 3. The slot 3 can be processed and shaped according to multiple parameters based on the diameter of the main reinforcement 8 in the area of ​​use. Multiple processing methods ensure wider applicability, facilitate on-site operation, greatly save manpower and resources, and provide strong support for rapid on-site construction. In this embodiment, the dimensions of the slot 3 and opening 4 can be designed according to 820mm main reinforcement and 910mm stirrup reinforcement.

[0043] Example 2:

[0044] This embodiment is a further improvement on embodiment 1. A clamping plate 5 is connected at the opening 4, and the clamping plate 5 is located at the end of the opening 4 near the handle 2. Preferably, the clamping plate 5 is designed as an arc-shaped plate, and the curved extension of the clamping plate 5 is the same as the curved extension of the clamping groove 3. Moreover, the clamping plate 5 and the bending body 1 are designed as an integrally formed structure. The purpose of designing the clamping plate 5 is to widen the bending angle. When the stirrup 9 is bent to a 90° angle, the main reinforcement 8 of the beam will affect the handle 2 from continuing to bend upward. If you want to continue bending, you can move the device until the stirrup 9 is located between the main reinforcement 8 and the clamping plate 5. In this way, using the lever principle, the clamping plate 5 is used to continue bending the stirrup 9 upward, such as bending it to a 135° angle.

[0045] Better still, in this embodiment, the bending body 1 and the handle 2 are detachably and fixedly connected. For example, a connecting nut 6 can be fixedly installed at one end of the bending body 1 near the handle 2, and the handle 2 is threadedly connected to the connecting nut 6.

[0046] To make the device more convenient to use, a hook 7 is fixedly connected to the end of the handle 2. The hook 7 can be a nut hook.

[0047] The operation procedure of the device using this embodiment is as follows:

[0048] 1. When using this device for bending, first, its U-shaped slot 3 is clamped onto the main reinforcement 8, and the straight section of the stirrup 9 is placed inside the device and the main reinforcement 8.

[0049] 2. According to the required bending direction, manually bend to 90° to achieve the desired shape. If some hooks need to be set to 135°, use the clamp plate 5 to fix the stirrup 9 to bend it to 135°.

[0050] 3. After bending to the correct position, loosen it in the opposite direction to remove the device. Then, hang it on the toolbox carried by the person using the nut hook 7.

[0051] This utility model can process multiple models of U-shaped slots 3 according to different types of steel bars, collect and carry them in a unified manner, and if a replacement is needed, simply twist the handle 2 rod and repeatedly replace the U-shaped slot 3 to meet the needs of on-site use. There is no need to carry multiple handles 2 rods at the same time, which is convenient and easy.

[0052] The stirrup bending device provided in this embodiment has the following advantages:

[0053] (1) It uses common conventional materials that can be obtained on-site, and the operation and construction are simple;

[0054] (2) The tool is formed in one step, with no maintenance costs in the later stage. It is easy to operate, highly applicable, and has a high reusability. (3) It can be processed by using different U-shaped slots of different sizes to meet the usage requirements of more parts.

[0055] It is made by bending by hand, which avoids the quality problems caused by repeated bending in existing technology, and has a certain guarantee effect on quality.

[0056] (4) The handle 2 is connected by a nut. The same handle 2 can carry multiple sets of U-shaped slots 3, which are convenient to assemble and make construction fast and efficient.

[0057] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
