Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar binding, and in particular relates to a steel bar binding device with a main bar spacing calibration structure. Background Art

[0002] The spacing of the main reinforcement of cast-in-place concrete in construction is obtained from the reinforcement design. There are often large deviations during on-site implementation, which in turn affects the stress of the main structure. The conventional practice is to lay out and mark before tying the steel bars. In order to ensure the spacing of the steel bars, the workers usually hold the tape measure in one hand and twist the wire in the other hand. The operation is more troublesome. If the skills of using the two are not mastered, it is easy to cause large errors in the spacing of the steel bars. In addition, since the workers are often negligent in control, they will measure and accept the spacing of the steel bars after the entire area is completed. If the requirements of the specifications are not met at this time, adjusting the spacing may affect the entire system, which is time-consuming and labor-intensive. To this end, we designed and proposed a steel bar tying device with a main reinforcement spacing calibration structure. Utility Model Content

[0020] The structural features of the utility model are now described in detail with reference to the accompanying drawings of the specification.

[0021] See also Figure 1-Figure 4A steel bar binding device with a main bar spacing calibration structure includes a wire hook 1, a rotating shaft 11 is fixedly connected to the wire hook 1, a handle 2 is sleeved on the rotating shaft 11, a thread 12 for driving the wire hook 1 to rotate is provided on the rotating shaft 11, and a thread pattern matching the thread 12 is provided in the handle 2. After the wire hook 1 hooks the main bar wire, the rotating shaft 11 will rotate in the handle 2 by pulling the handle 2 upward, so that the wire hook 1 can tie the wire between the main bars. In order to determine the spacing of the main bars while tying the wires, an axle seat 21 is fixedly provided on one side of the bottom of the handle 2, and a measuring component for the spacing of the cast-in-place concrete main bars is movably connected to the axle seat 21, and the length of the measuring component is adjustable. The measuring assembly includes a first bar 3 and a second bar 4. The second bar 4 is inserted into the first bar 3. One end of the first bar 3 is rotatably connected to the shaft seat 21, and the other end is provided with a locking bolt 31 for fixing the second bar 4. The second bar 4 is provided with a scale 41 along the length direction. When tying the wire, the main reinforcement spacing is determined by unscrewing the first bar 3 and putting it in a horizontal state, and then adjusting the length of the second bar 4. The adjustment of the second bar 4 can make the measuring assembly suitable for different main reinforcement spacings. After the adjustment is completed, the extended length of the second bar 4 is limited and fixed by the locking bolt 31. In order to make the main reinforcement spacing more accurately calibrated, a support 42 is fixedly provided at one end of the second bar 4 away from the first bar 3. The support 42 is rotatably connected to the marking needle 5. When the first bar 3 is in a horizontal state, the end of the marking needle 5 is lower than the bottom of the wire tying hook 1. When tying the wire, the marking needle 5 can be placed on the main reinforcement that has been tied nearby, so that the main reinforcement spacing can be more accurately defined and the error of the main reinforcement spacing of the wire tying can be reduced. In order to facilitate the storage of the measuring component, a slot 22 is provided at the top of the handle 2 corresponding to the position of the first marker 3. The slot 22 is a rubber elastic part. After use, the second marker 4 can be put into the first marker 3, the marker needle 5 can be folded on the outside of the first marker 3, and the first marker 3 can be rotated upward and folded into the slot 22 to achieve the folding and fixation of the first marker 3, which is convenient for the storage of the steel bar binding device.

[0022] In order to improve the comfort of the operators in using the steel bar tying device with the main bar spacing calibration structure, a pressing portion 24 for the thumb to rest on is provided above the handle 2 on one side of the measuring component, and a gripping portion 23 is provided on the side away from the measuring component. This allows the operators to hold the handle 2 more comfortably and stably, avoiding the grip slipping during the wire tying process.

[0023] The utility model provides a steel bar binding device with a main bar spacing calibration structure, which organically combines a measuring component for measuring the main bar spacing and a wire hook 2 for steel bar binding. The length of the measuring component can be adjusted according to the main bar spacing. The main bar spacing can be calibrated while the wires are being tied, thus eliminating the trouble of holding a measuring tape with one hand and twisting the wire with the other hand. The device can be checked and adjusted at the same time to ensure the quality of steel bar binding.

[0024] Specifically, when in use, the first marking rod 3 is rotated and unfolded to be in a horizontal state, and then the second marking rod 4 is pulled out, adjusted to the required measuring distance, and then fixed, and finally the marking needle 5 is rotated downward and unfolded. When tying the wire, the wire tying hook 1 hooks the main reinforcement to be tied, so that the marking needle 5 faces the side of the main reinforcement that has been tied, and the distance between the main reinforcement to be tied and the main reinforcement that has been tied is adjusted. After the marking needle 5 is completely against the main reinforcement that has been tied, the wire tying operation can be performed on the main reinforcement to be tied.
