[0027] refer to Figures 1 to 2 The stirrup bending device according to the embodiment of the utility model is described.
[0028] like Figure 1 to Figure 2 As shown, the stirrup bending device includes a cylinder 100, which is axially penetrated with an opening 110, and the cylinder 100 is sleeved on the main reinforcement 20 through the opening 110. A limiting groove 120 and a giving groove 130 are circumferentially provided on the cylinder 100, and the giving groove 130 is connected with the limiting groove 120. The limiting groove 120 is used to limit the position of the stirrup 10, and the giving groove 130 is used to give way to the bending hook of the stirrup 10; a handle 200, and the handle 200 is arranged at the end of the cylinder 100 opposite to the opening 110.
[0029] Stirrups 10 refer to a kind of steel reinforcement material used to reinforce and strengthen concrete structures in construction and civil engineering. They are usually made of steel bars and have high strength and corrosion resistance. The main function of stirrups 10 is to increase the seismic resistance and bearing capacity of concrete structures and prevent concrete from cracking or breaking when subjected to stress. Specifically, stirrups 10 are generally wrapped around concrete components such as columns, beams and slabs in a ring or straight line form. It can resist the tensile force of concrete when subjected to stress, prevent the expansion and contraction of concrete, and thus increase the stability and durability of the structure. During the construction of concrete structures, stirrups 10 will be arranged and fixed according to design requirements and the stress conditions of the structure, and parameters such as diameter, spacing and number will be calculated and determined according to specific engineering requirements.
[0030] Among them, the hook of the stirrup 10 refers to the hook-shaped part formed by bending at one or both ends of the stirrup 10. The hook of the stirrup 10 is usually used to connect concrete components to increase the tensile strength and connection strength of the structure. The hook of the stirrup 10 can provide a tensile connection in the concrete component by bending one or both ends of the stirrup 10 into a hook shape, so as to increase the connection area and friction and provide stronger tensile strength. At the same time, the hook-shaped part can form a mechanical anchoring effect between the stirrup 10 and the concrete to prevent the stirrup 10 from sliding or falling off, thereby improving the overall strength and stability of the concrete structure. During the construction process, the hook of the stirrup 10 can simplify the construction operation. The shape of the hook makes the stirrup 10 easier to hold and handle during the installation and connection process, which is convenient for operators to carry out construction. At the same time, the presence of the hook of the stirrup 10 can also provide visual identification to ensure that the stirrup 10 is correctly installed and connected.
[0031] like Figure 1 and Figure 2As shown, the cylinder 100 extends in the left-right direction, and an opening 110 is provided on the left and right sides of the cylinder wall of the cylinder 100. The opening 110 extends linearly in the left-right direction and penetrates the cylinder 100, and the handle 200 is provided at the rear side of the cylinder 100. Specifically, a clearance groove 130 and a limiting groove 120 are sequentially provided on the cylinder 100 in the front-to-back direction, and the notch of the limiting groove 120 corresponds to the diameter of the stirrup 10, and the notch of the clearance groove 130 corresponds to at least twice the diameter of the stirrup 10. Therefore, when bending the stirrup 10 on site, first pass the stirrup 10 through the opening 110 and insert the stirrup 10 into the limiting groove 120. At this time, the extension direction of the stirrup 10 is perpendicular to the axial direction of the cylinder 100. Then, the main reinforcement 20 passes through the cylinder 100 along the axial direction of the cylinder 100. At this time, the extension directions of the main reinforcement 20 and the stirrup 10 are perpendicular to each other. Fix one end of the stirrup 10, hold the handle 200 and rotate the cylinder 100 with the axis of the cylinder 100 as the axis, and the stirrup 10 and the main reinforcement 20 are pressed against each other. At the same time, unlike the installation of stirrups 10 manufactured in a processing plant, there is no need to break open the processed fixed-length stirrups 10 hooks for installation, thus avoiding damage to the stirrups 10, and there is no loss during construction, which is economical and saves manpower.
[0032] In some specific embodiments of the present invention, the clearance groove 130 and the limiting groove 120 are coaxially arranged along the diameter direction of the cylinder 100. Figure 2 As shown, the give-way groove 130 is arranged on the cylinder 100, and the give-way groove 130 and the opening 110 are located on the same side. Similarly, the limit groove 120 is arranged on the cylinder 100, and the limit groove 120 and the opening 110 are located on the same side, wherein the give-way groove 130 is located between the opening 110 and the limit groove 120. Specifically, the give-way groove 130 and the limit groove 120 are coaxially arranged along the front-to-back direction.
[0033] In some specific embodiments of the present invention, the length of the clearance groove 130 extending along the axial direction of the cylinder 100 is greater than the length of the limiting groove 120 extending along the axial direction of the cylinder 100. Figure 2 As shown, the length of the give way groove 130 extending in the left-right direction is greater than the length of the limit groove 120 extending in the left-right direction. In this specific embodiment, the give way groove 130 can accommodate the diameter of one stirrup 10, and the give way groove 130 can accommodate the diameter of three stirrups 10, that is, after the stirrup 10 is bent around the main reinforcement 20 for one circle, since the continued bending of the stirrup 10 will produce overlapping parts, the give way groove 130 can make way for the first circle of overlapping stirrups 10 to ensure that the remaining part of the stirrup 10 after bending for one circle can continue to bend around the main reinforcement 20.
[0034] Of course, the clearance groove 130 and the limiting groove 120 can also be set in different axes, as long as the length of the clearance groove 130 extending axially along the cylinder 100 is greater than the length of the limiting groove 120 extending axially along the cylinder 100, and the depth of the clearance groove 130 extending outward along the edge of the limiting groove 120 is sufficient to accommodate the diameter of a stirrup 10, the bending operation of the stirrup 10 can be achieved.
[0035] In some specific embodiments of the present invention, the handle 200 , the clearance groove 130 and the limiting groove 120 are coaxially arranged along the diameter direction of the cylinder 100 .
[0036] like Figure 2 As shown, the handle 200 extends in the front-to-back direction, and the extension direction of the handle 200 is perpendicular to the wall of the cylinder 100. The handle 200, the clearance groove 130 and the limit groove 120 are coaxially arranged in the front-to-back direction. The operator can apply force by rotating the handle 200 to bend the steel bar to the desired angle without additional force adjustment or repositioning, thereby improving the bending efficiency and making the operation more convenient and efficient. At the same time, setting the bending handle 200 coaxially with the steel bar can make the operator more stable when applying force, improve the bending accuracy, reduce the loss of force in the conversion process, reduce the angle deviation caused by inaccurate or unstable operation, and ensure that the steel bar is bent to a predetermined angle.
[0037] In some specific embodiments of the present invention, the barrel 100 is made of steel.
[0038] Steel has excellent strength and durability, as well as high plasticity and machinability. It is easy to form, process and manufacture. It can also withstand high-intensity forces and repeated use. It can be customized and adjusted as needed to adapt to stirrups 10 of different specifications and sizes to meet various bending requirements. When bending stirrups 10, it is necessary to withstand greater pressure and stress. The use of steel can ensure the structural stability and durability of the device, and it is not easy to deform or damage, thereby maintaining the shape and performance of the equipment for a long time.
[0039] Secondly, steel generally has good corrosion resistance and can resist corrosion and oxidation in harsh environments. On construction sites or other wet, dusty, chemically exposed environments, stirrup bending devices may be exposed to corrosive substances. Therefore, using steel with good corrosion resistance can extend the service life of the equipment and reduce the frequency of maintenance and replacement.
[0040] In some specific embodiments of the present invention, a gripping portion 210 is provided on the handle 200 , and the gripping portion 210 is used for the user to hold it easily.
[0041] The handle 200 is provided with a gripping portion 210. In this specific embodiment, the gripping portion 210 is a columnar structure with a cross-sectional area larger than the handle 200, and the gripping portion 210 smoothly transitions with the handle 200. It is conceivable that the gripping portion 210 can also be any other structure that can increase the contact area with the operator's hand, so as to provide stable control, so that the operator can firmly hold the stirrup bending device. At the same time, the gripping portion 210 provides a good hand feel and gripping point, reduces the risk of sliding and loss of control, ensures the stability and accuracy of the operation, and is convenient for construction personnel to hold at multiple angles.
[0042] Furthermore, a plurality of friction protrusions 211 are provided on the gripping portion 210, and the plurality of friction protrusions 211 are arranged in sequence along the front-to-back direction. The plurality of friction protrusions 211 can prevent the hands of construction workers from slipping off the gripping portion 210, so as to help the construction workers to effectively exert force on the gripping portion 210 and reduce the force burden of the operator.
[0043] In some specific embodiments of the present invention, the width of the opening 110 is greater than the diameter of the main rib 20 .
[0044] Specifically, the cross section of the cylinder 100 is an arc, that is, the cylinder 100 is an arc cylinder cut through along the axial direction of the cylinder where the cylinder 100 is located. In this specific embodiment, the depth of the cylinder 100 refers to the maximum length of the cylinder 100 in the front-to-back direction, and the depth is two-thirds of the diameter of the circle where the cylinder 100 is located. Of course, the depth of the cylinder 100 can also be any other length that can accommodate the passage of the main reinforcement, so that the operator can directly put the cylinder 100 on the main reinforcement 20, so that the cylinder 100 surrounds the main reinforcement 20 in a wrapped shape.
[0045] In some specific embodiments of the utility model, when the stirrup 10 is bent on site, the stirrup 10 is first passed through the opening 110, and the stirrup 10 is inserted into the limiting groove 120, and the hook of the stirrup 10 is buckled into the main reinforcement 20, and then the main reinforcement 20 is passed through the cylinder 100 along the axial direction of the cylinder 100. At this time, the main reinforcement 20 and the stirrup 10 are perpendicular to each other, and the hook enables one end of the stirrup 10 to be fixed on the main reinforcement 20. The handle 200 is held and the cylinder 100 is rotated with the axis of the cylinder 100 as the axis. The stirrup 10 and the main reinforcement 20 are pressed against each other. Under the principle of leverage, the other end of the stirrup 10 is rotated around the main reinforcement 20 and bent to a required angle.
[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
