Description

Technical Field

[0001] The utility model relates to the technical field of concrete components, in particular to a reinforcement tool for concrete components. Background Art

[0002] Concrete components refer to components or structures of various shapes and sizes that are cast using formwork using two materials, steel bars and concrete, in accordance with design requirements. That is, the basic structure of concrete component production is concrete material and steel bars or steel cages bundled with steel bars.

[0003] The steel cage is composed of multiple steel columns and several stirrups. The stirrups are smaller steel bars. When bundling, the stirrups are attached to the steel columns, and then the stirrups are bent around multiple steel columns and tied with steel wire to form a steel cage. In order to speed up the bundling of stirrups, a grab hook has appeared on the market. The grab hook is U-shaped or Y-shaped, forming two arc-shaped claws. The two claws are buckled on the steel column. The handle end of the grab hook is against the stirrup, and then the grab hook is deflected around the steel column to complete the bundling, which is quick and convenient. However, it should be noted that the stirrups are straight at the beginning. When they are just bent on the steel column, there is no force point at the end of the stirrup. It is easy to deflect with the grab hook at the same time. If you use your hands to help, if you are operating alone, holding the grab hook with one hand and pressing the stirrup with the other hand, not only is the posture inconvenient to exert force, but the hand holding the stirrup is also easy to lose strength, which is easy to cause scratches.

[0004] To this end, the utility model provides a reinforcement tool for a concrete member, which solves the problem of positioning and fixing the stirrups when they are just beginning to bend. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a reinforcement tool for concrete components.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0017] Preferably, the two claws of the first grab hook are each provided with a rotating shaft at one opposite end, and the surfaces of the two claws of the second grab hook are each provided with an arc-shaped buckle that cooperates with the rotating shaft.

[0018] Compared with the prior art, the utility model provides a reinforcement tool for concrete components, which has the following beneficial effects:

[0019] 1. This embodiment provides a reinforcement tool for concrete components, including a reinforcement assembly and a limit assembly:

[0020] The reinforcing bar assembly comprises a handle end, and a U-shaped first grab hook is provided at the bottom of the handle end;

[0021] The limiting assembly comprises a connecting handle, and two ends of the connecting handle are symmetrically provided with U-shaped second grab hooks.

[0022] When in use, the second hooks at both ends of the connecting handle are buckled on a steel bar column respectively, and then the movable end of the stirrup is passed between the two claws of the second hook above; holding the handle end, the first hook is buckled on the steel bar column corresponding to the second hook above, and then the handle end is pressed, and the handle end is rotated around the steel bar column to cover the stirrup. Since the movable end of the stirrup is against the side wall of the connecting handle and the handle end is covered, the stirrup will not rise. After the initial bending of the stirrup is completed, the first hook is removed, and then the first hook is buckled on the next steel bar column to bend the next stirrup. The whole process does not require hand support for the stirrup, thereby avoiding the problem of uncomfortable posture of supporting the stirrup with one hand and pressing the first hook with the other hand, which is inconvenient to exert force, and the problem of incorrect posture causing the movable end of the stirrup to slip out of the hand and be scratched, thereby improving the safety of use and the efficiency of reinforcement tying.

[0023] 2. A pressure plate is provided between the two claws of the first grab hook. The existence of the pressure plate makes it possible for the end of the stirrup to fail to contact the side wall of the handle end when the first grab hook is buckled on the steel bar column during the last bend of the stirrup, and the pressure plate can be pressed on the end of the stirrup to achieve the bending of the end of the stirrup, thereby improving the practicality of use.

[0024] 3. Connecting tubes are slidably installed at both ends of the connecting handle along the length direction. Two second grab hooks are symmetrically fixed on the ends of the connecting tubes on the corresponding sides, so that the second grab hooks can move relative to the connecting handle. The distance between the two grab hooks is adjustable, which makes it easy for the second grab hooks of the connecting handle section to respectively buckle the two steel bars. It is also suitable for bundling two adjacent steel bars at different distances, thereby improving practicality and applicability.

[0025] 4. A storage tube is provided on the handle end, and a telescopic handle is slidably installed in the storage tube, so that the length of the handle end can be adjusted, that is, the pressing force arm is adjustable. The longer the force arm is, the smaller the force required to be applied, the more labor-saving it is, and the more convenient it is to use.

[0026] 5. Rotating shafts are provided at opposite ends of the two claws of the first grab hook, and arc buckles are provided on the surfaces of the two claws of the second grab hook. When in use, the rotating shaft is embedded into the arc buckle from the open end of the arc buckle, and then the first grab hook is buckled on the steel column. In this way, the first grab hook is connected to the second grab hook through the rotating shaft and the arc buckle and acts on the steel column. In this way, even if one claw of the first grab hook is located on the steel column and is suspended outside the steel column, it can be used normally.

[0027] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present invention.

[0034] The following will be combined with the attached embodiment of the utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0035] Embodiment 1, in order to solve the problems existing in the prior art, this embodiment provides a reinforcement tool for concrete components, including a reinforcement assembly and a limit assembly:

[0036] The reinforcing bar assembly comprises a handle end 3, a U-shaped first grab hook 4 is provided at the bottom of the handle end 3, and a pressing plate 7 is provided between two claws of the first grab hook 4;

[0037] The limiting assembly comprises a connecting handle 5, and two ends of the connecting handle 5 are symmetrically provided with U-shaped second grab hooks 6;

[0038] The distance between the two claws of the first grab hook 4 is greater than the width of the second grab hook 6 , and the distance between the two claws of the second grab hook 6 is greater than the width of the pressing plate 7 .

[0039] When in use, the second hooks 6 at both ends of the connecting handle 5 are buckled on a steel bar column 1 respectively, and then the movable end of the stirrup 2 is inserted between the two claws of the second hook 6 above and pressed against a steel bar column 1, and then the handle end 3 is held, and the first hook 4 is buckled on the steel bar column 1 corresponding to the second hook 6 above, and the first hook 4 buckles the second hook 6 in the two claws of the first hook 4, as shown in the attached figure. Figure 1 As shown, at this time, the handle end 3 is against the side wall of the stirrup 2, and then the handle end 3 is pressed, and the handle end 3 is rotated around the steel column 1, so as to cover the stirrup 2. Since the movable end of the stirrup 2 is against the side wall of the connecting handle 5 and the handle end 3 is pressed, the stirrup 2 will be pressed into a desired angle without curling up. After completing the initial bending of the stirrup 2, the first grab hook 4 is removed, and then the first grab hook 4 is buckled on the next steel column 1 to perform the next bending of the stirrup 2. The whole process does not require the movable end of the stirrup 2 to be supported by hand, thereby avoiding the uncomfortable posture of supporting the stirrup 2 with one hand and pressing the first grab hook 4 with the other hand, which is inconvenient to exert force, and the problem that the movable end of the stirrup 2 is easy to slip out of the hand and get scratched due to incorrect posture, thereby improving the safety of use and the efficiency of reinforcement tying.

[0040] The presence of the pressure plate 7 means that when the first hook 4 is buckled on the steel column 1 during the last bend of the tied stirrup 2, the end of the stirrup 2 cannot contact the side wall of the handle end 3. At this time, the pressure plate 7 can be pressed on the end of the stirrup 2 to achieve the bending of the end of the stirrup 2, thereby improving the practicality of use.

[0041] In Example 2, both ends of the connecting handle 5 are slidably installed with connecting tubes 8 along the length direction, and two second grab hooks 6 are symmetrically fixed on the ends of the connecting tube 8 on the corresponding sides. The two connecting tubes 8 and the ends of the connecting handle 5 are provided with springs, so that the second grab hooks 6 can move relative to the connecting handle 5. The distance between the two grab hooks is adjustable, which makes it easy for the second grab hooks 6 of the connecting handle 5 to respectively buckle the two steel bars 1. It is also suitable for bundling two adjacent steel bars 1 with different distances, thereby improving practicality and applicability.

[0042] In Example 3, a stud is fixed at the end of the pressure plate 7, and a threaded hole is provided at the center line of the first grab hook 4. The stud is threadedly connected to the threaded hole, so that the pressure plate 7 can be replaced when it warps after long-term use.

[0043] In embodiment 4, a storage tube 9 is provided on the handle end 3, and a telescopic handle 10 is slidably installed in the storage tube 9, so that the length of the handle end 3 is adjustable, that is, the pressing force arm is adjustable. The longer the force arm is, the smaller the force required to be applied, the more labor-saving, and the more convenient to use; the telescopic handle 10 extends out of the storage tube 9 and is fixed with a grip handle at one end, making it more comfortable to hold.

[0044] A damping is provided between the telescopic handle 10 and the storage tube 9. The damping is any one of air damping and friction damping, so that the retracted disease will not easily extend out of the storage tube 9.

[0045] Embodiment 5, since the reinforcement is arranged at intervals along the steel column 1, when the reinforcement is tied to the side of the steel column 1, one side claw of the first grab hook 4 may not be able to buckle the steel column 1, and it is not convenient to press and exert force at this time. Therefore, in this embodiment, a rotating shaft 11 is set at the opposite ends of the two claws of the first grab hook 4, and the surfaces of the two claws of the second grab hook 6 are provided with an arc buckle 12 that cooperates with the rotating shaft 11. One end of the arc buckle 12 is open. When in use, the rotating shaft 11 is embedded in the arc buckle 12 from the open end of the arc buckle 12, and then the first grab hook 4 is buckled on the steel column 1. In this way, through the rotating shaft 11 and the arc buckle 12, the first grab hook 4 is connected with the second grab hook 6 and acts on the steel column 1, so that the operation can be performed.
