[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0030] Reference Figure 1-10 The utility model discloses a stirrup bending tool, comprising an operating rod 2, one end of which is provided with a third U-shaped groove 5 along the axial direction, the third U-shaped groove 5 radially penetrates the operating rod 2, and bending steps 31 are provided on both sides of the opening of the third U-shaped groove 5, and main reinforcement hooks 4 are respectively provided on the sides of the two bending steps 31 away from each other. Figure 3 The up and down direction shown), the axial direction of the main reinforcement hook 4 (as shown Figure 3 The left and right directions shown in FIG. 1 ), the penetration direction of the third U-shaped groove 5 (as shown in FIG. Figure 3 The front-to-back directions shown) are perpendicular to each other.
[0031] The dimensions of the operating rod 2, the third U-shaped groove 5, the bending step 31, and the main reinforcement hook 4 are determined according to actual needs. For example, the radial dimension of the operating rod 2 is mainly selected according to the size of the user's palm, and the length of the operating rod 2 is selected according to the user's height and operating habits. The size of the third U-shaped groove 5 is related to the size specifications of the stirrups.
[0032] The specific operation method is as follows Figure 5 As shown in FIG. 1 , the main reinforcement 6 and the stirrup 7 of the beam column are perpendicular to each other. After the main reinforcement hook 4 is hooked on the main reinforcement 6, when the stirrup 7 is bent, as shown in FIG. Figure 6 As shown, the end of the stirrup 7 located below is bent upward to form a Figure 7 The effect is shown, and then Figure 8-9 , bend the other end of the stirrup 7 located above downward, and finally Fig.10 , bend the first bent end toward the inside of the beam column, and the bending work of the temporary stirrup 7 is completed.
[0033] Generally speaking, an important action when using the tool is to hook the main bar hook 4 on the main bar 6, and then rotate the operating rod 2 to squeeze one end of the stirrup 7 through the bending step 31, so that one end of the stirrup 7 is bent. Therefore, the farther the distance between the two main bar hooks 4 is, the smoother the rotation of the operating rod 2 can be ensured. Figure 1-4 The main reinforcement hook 4 shown can also be used to connect the bottom of the operating rod 2 and the main reinforcement hook 4 through a transversely arranged connecting rod, thereby increasing the distance between the two main reinforcement hooks 4 and improving the stability of the operating rod 2 when rotating.
[0034] A first U-shaped groove 3 with an opening facing downward is provided at the bottom of the operating rod 2, and a third U-shaped groove 5 with an opening facing downward is provided at the top of the first U-shaped groove 3. The first U-shaped groove 3 penetrates the operating rod 2, and the penetration directions of the first U-shaped groove 3 and the third U-shaped groove 5 are the same. The radial dimension of the first U-shaped groove 3 is larger than that of the third U-shaped groove 5, so that bending steps 31 are formed on both sides of the top of the first U-shaped groove 3, and the main reinforcement hooks 4 are located on both sides of the first U-shaped groove 3.
[0035] The main reinforcement hook 4 can be welded on both sides of the outer wall of the first U-shaped groove 3. Figure 6 , hook the main bar hook 4 on the main bar 6 from the inside to the outside, then use the bending step 31 to squeeze the stirrup 7 downward, bend the end of the stirrup 7 downward, and then Fig.10 , rotate the operating rod 2 in the opposite direction, use the bending step 31 on the other side to squeeze the other end of the stirrup 7, and bend the other end toward the inside of the beam column.
[0036] The main reinforcement hook 4 includes a second U-shaped groove 41 opened on both side walls of the first U-shaped groove 3 . The opening direction of the second U-shaped groove 41 is the same as the penetrating direction of the first U-shaped groove 3 and the third U-shaped groove 5 .
[0037] That is, the main reinforcement hook 4 and the first U-shaped groove 3 are an integrated structure, which is easy to process.
[0038] The second U-shaped groove 41 is arranged obliquely, so that the opening direction of the second U-shaped groove 41 is inclined upward.
[0039] When the operating rod 2 is hooked on the main reinforcement 6 through the second U-shaped groove 41 and rotated around the circumference of the main reinforcement 6, it is convenient to pull the operating rod 2 to the side away from the main reinforcement 6 to prevent the second U-shaped groove 41 from being separated from the main reinforcement 6.
[0040] Grooves 32 are provided at both the front and rear ends of the main reinforcement hook 4 .
[0041] The groove 32 extends downward to the bottom of the operating rod 2. When the operating rod 2 is made of a hollow round tube or a seamless steel tube, processing the groove 32 is reasonable to further increase the horizontal size of the bending step 31, so that the stirrup 7 can be clamped more stably, preventing the stirrup 7 from detaching from the bending step 31 toward the side where the third U-shaped groove 5 is located during the bending process.
[0042] A rubber handle 1 is provided at one end of the operating rod 2 away from the third U-shaped groove 5 .
[0043] It is convenient for the user to hold the operating rod 2 for operation.
[0044] The operating rod 2 is a hollow tube.
[0045] The overall weight of the tool is reduced, and the user's physical exertion is reduced.
[0046] The operating rod 2 is a seamless steel pipe.
[0047] The structural strength of the operating rod 2 is ensured.
[0048] The radial dimension of the bending step 31 is not less than half of the radial dimension of the third U-shaped groove 5 .
[0049] The third U-shaped groove 5 can pass through two side-by-side stirrups 7 at the same time, and the bending step 31 bends one of the stirrups 7 at a time, that is, the width of the bending step 31 is slightly larger than the diameter of the stirrup 7, further preventing the stirrup 7 from detaching from the bending step 31.
[0050] Example 1
[0051] Processing
[0052] Step 1: Cut a 40cm long Φ40mm seamless steel pipe as the operating rod 2, and use a cutting machine to cut a third U-shaped groove 15 with a width of 15mm and a length of 150mm from one end of the operating rod 2;
[0053] Step 2: widen the third U-shaped groove 15 at a distance of about 60 mm from the end of the steel pipe to form a first U-shaped groove 3 of 60 mm length and 30 mm width;
[0054] Step 3: symmetrically cut the tube wall on both sides of the slot at a position 7 mm away from the slot end to form a second U-shaped slot 41. The depth of the second U-shaped slot 41 is determined according to the diameter of the main reinforcement of the beam column surrounded by the stirrup to be bent. After the processing is completed, the end of the operating rod 2 looks like a hook from the side.
[0055] Step 4: Put on the rubber handle 1 that matches the operating rod 2 to complete the processing of the stirrup tool.
[0056] Working principle: When temporarily adding stirrups to beams and columns during construction, take a section of stirrup steel bars that meet the design requirements, first manually or mechanically bend them two 90°, the bending size matches the main reinforcement size and interface position, then put the stirrups on the main reinforcement position, and use the hook at the end of the bending tool;
[0057] Hook the main reinforcement hook 4 onto the main reinforcement 6 of the beam column so that the two ends of the stirrup 7 to be bent are located between the two main reinforcement hooks 4, clamp one end of the stirrup through the bending step 31 on one side, rotate the operating rod 2 around the main reinforcement 6, and bend the end of the stirrup 7 clamped by the bending step 31 to a predetermined angle. The same operation is performed to reversely bend the other end of the stirrup 7, so that the stirrup 7 to be temporarily added is installed on the main reinforcement 6, and finally use the wire to bind the connection between the stirrup and the main reinforcement to complete the construction of a stirrup.
