Description

Technical Field

[0001] This utility model relates to the field of spiral ribbed steel bar technology, specifically a spiral ribbed steel bar fixing device. Background Technology

[0002] Spiral ribbed steel bars are a type of material that can be used in spiral ribbed steel bars to improve the mechanical properties of concrete by pre-stressing it. Adding spiral ribs to spiral ribbed steel bars allows the applied prestress to restrain concrete deformation, increasing structural stiffness, thereby ensuring structural stability and extending service life.

[0003] Currently, the fixing device for spiral ribbed steel bars involves inserting multiple spiral ribbed steel bars through the middle of the concrete, then connecting them to a joint, and finally connecting the joint to the end of the concrete to add multiple spiral ribbed steel bars. The connection between the spiral ribbed steel bars and the joint involves first adding a threaded post to the end of the spiral ribbed steel bar, then inserting the threaded post through the joint, and finally tightening it with a nut. However, this connection method requires repeated disassembly and assembly of multiple bolts, which is time-consuming and labor-intensive, negatively impacting the efficiency of disassembly and assembly. Therefore, it is necessary to provide a spiral ribbed steel bar fixing device that can solve the above-mentioned drawbacks to improve the related performance. Utility Model Content

[0004] The purpose of this utility model is to provide a spiral ribbed steel bar fixing device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a spiral ribbed steel bar fixing device, comprising: A steel reinforcement fixing structure, wherein the steel reinforcement fixing structure includes a plurality of steel bars that extend equidistantly through the concrete; The docking structure includes docking frames symmetrically fixedly connected to the ends of spiral ribbed steel bars. The docking frames have docking interfaces equidistantly through the middle, and holes are fixed on opposite sides of the inner wall of the docking interfaces. A torsion spring is through the middle of the hole block, and a docking block is fixed inside the torsion spring. A limiting block is provided on the upper part of the inner side of the hole block and abuts against the upper end of the docking block. A docking post is sleeved on one end of the inner wall of the docking interface and extends into the docking interface.

[0005] Furthermore, a columnar protrusion is provided at the center of one end of the limiting block, and a groove is provided on the upper part of the inner side of the hole block corresponding to the columnar protrusion, and fits into the columnar protrusion.

[0006] Furthermore, the steel bar fixing structure also includes threaded columns symmetrically fixed at the upper and lower ends of the steel bar, and the outer side of the threaded column is threaded with a movable head.

[0007] Furthermore, it also includes a regular structure, which includes an opening through the middle of the movable head, a movable column protruding from the middle of the opening, and a regular rope fixedly connected to one end of the movable column.

[0008] Furthermore, the other end of the movable column is threadedly connected to a limit ring, and one side of the limit ring abuts against the movable head.

[0009] Furthermore, the regular structure also includes a collar that fits onto one side of the outer surface of the movable head, wherein a magnetic ring is snapped into the middle of the outer surface of the collar and magnetically attracts the outer surface of the movable head.

[0010] This utility model has the following beneficial effects: This invention features multiple through-hole interfaces in the middle of the connecting frame, with connecting blocks connected to the inner wall of the interfaces via torsion springs. After the movable head of the rebar end extends to the interface, the connecting block, under stress, moves to one side, allowing it to smoothly extend to the inside of the limiting block. Subsequently, connecting posts are fitted into the interfaces. The contact between the connecting posts and one end of the movable head, as well as the contact between the rebar end and the limiting block caused by the reverse movement of the connecting block, allows for convenient and quick installation of the rebar end. The above steps eliminate the need to disassemble and assemble multiple bolts to structurally fix the rebar, saving time and effort, and improving work efficiency and performance, thus meeting the requirements.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 As shown, this utility model is a spiral ribbed steel bar fixing device, comprising: The steel reinforcement 11 fixing structure includes a plurality of steel reinforcement 11 that are equidistantly inserted and extend into the concrete. The reinforcing bars 11 are placed in the concrete to restrain concrete deformation, improve structural stiffness, extend the service life of the concrete, and ensure the stability of the structure.

[0017] The fixing structure of the reinforcing bar 11 also includes threaded columns 12 symmetrically fixed at the upper and lower ends of the reinforcing bar 11, and the outer side of the threaded column 12 is threaded with a movable head 13; The threaded column 12 connects the end of the reinforcing bar 11 to the movable head 13, which connects the reinforcing bar 11 to the connecting frame 21.

[0018] The docking structure includes a docking frame 21 symmetrically fixedly connected to the end of the spiral rib steel bar. The docking frame 21 has a docking interface 22 equidistantly through the middle. The inner walls of the docking interface 22 are fixed with holes 23 on opposite sides. The middle of the holes 23 is connected with a torsion spring 24. The inner side of the torsion spring 24 is fixed with a docking block 25. The upper part of the inner side of the holes 23 is provided with a limiting block 26, which abuts against the upper end of the docking block 25. One end of the inner wall of the docking interface 22 is fitted with a docking post 27, which extends into the docking interface 22. The interface 22 uses the hole block 23 and the torsion spring 24 to fix the structure of the docking block 25. Then, with the contact between the docking block 25 and the limiting block 26, the contact between the movable head 13 and the docking block 25, and the contact between the docking column 27 and the movable head 13, the movable head 13 can be connected to the docking frame 21 in a convenient and quick manner. The docking frame 21 is then connected to the end of the concrete, so that the connection between the steel bar 11 and the concrete can be completed quickly and easily.

[0019] The limiting block 26 has a columnar protrusion at the middle of one end, and the upper part of the inner side of the hole block 23 has a groove corresponding to the columnar protrusion and fits into the columnar protrusion. The fitting between the columnar protrusions and grooves secures them to the hole block 23.

[0020] Working principle: When connecting and fixing the steel bar 11 to the concrete, the movable head 13 is pre-threaded to the outer side of the threaded column 12. Then, multiple movable heads 13 are extended to one end of the interface 22 in sequence. During the gradual extension, the movable head 13 contacts the docking block 25 and transmits force. The torsion spring 24 affected by the force deforms, causing the docking block 25 to move to one side, allowing the movable head 13 to extend smoothly into the depth of the interface 22. After the gap generated by the movement of the docking block 25 is sufficient for the movable head 13 to enter, the force is released, causing the torsion spring 24 to return to its original deformation, prompting the docking block 25 to return to its original state. Then, the docking column 27 is extended to the other end of the interface 22 until it abuts against one end of the movable head 13. During this process, the other end of the movable head 13 abuts against the docking block 25. After being subjected to force, the docking block 25 abuts against the limiting block 26, which can ensure a tight connection between the movable head 13 and the docking frame 21. Subsequently, the docking frame 21 is interference-fitted to the end of the concrete.

[0021] This solution can fix the steel bar 11 structurally without the need to disassemble and assemble multiple bolts, saving time and effort, and is convenient and quick, which helps to improve work efficiency and usage effect, and meets the requirements.

[0022] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The regular structure includes an opening 31 that runs through the middle of the movable head 13, a movable column 32 that extends through the middle of the opening 31, and a regular rope 36 that is fixedly connected to one end of the movable column 32. The other end of the movable column 32 is threadedly connected to a limit ring 33, and one side of the limit ring 33 abuts against the movable head 13; The opening 31 allows the movable column 32 to pass through. With the help of the limiting ring 33, one end of the movable column 32 can be locked, and the other end is used for receiving and installing the straightening rope 36. The straightening rope 36 can be used to wrap and limit the multiple steel bars 11 in the storage, so as to facilitate storage.

[0023] The regular structure also includes a collar 34 that fits onto one side of the outer surface of the movable head 13. A magnetic ring 35 is snapped into the middle of the outer surface of the collar 34 and magnetically attracted to the outer surface of the movable head 13. The collar 34 restricts the installation of the magnetic ring 35. With the help of the magnetic attraction between the magnetic ring 35 and the surface of the movable head 13, multiple stacked steel bars 11 can be initially fixed, which is conducive to the subsequent secondary locking and straightening treatment of the straightening rope 36.

[0024] Working principle: After the reinforcing bars 11 are disassembled or not in use, the movable column 32 is inserted into the opening 31, and force is applied to the threaded upper limit ring 33 on one side of the outer surface of the movable column 32 so that the limit ring 33 abuts against the outer surface of the movable head 13. Then, a collar 34 is fitted onto the outer surface of the movable head 13. At this time, multiple reinforcing bars 11 to be neatly stored can be stacked on each other. With the help of the magnetic ring 35 on the outer surface of the collar 34 and the magnetic attraction between the magnetic ring 35 and the surface of the movable head 13, the stacked reinforcing bars 11 can be initially fixed. Then, with the help of the straightening rope 36 at the other end of the movable column 32, multiple reinforcing bars 11 can be wrapped to further restrict them. Afterwards, they can be placed in the storage position.

[0025] This solution, by using the movable head 13 to facilitate the connection and installation of the steel bars 11, can also meet the needs for subsequent neat storage, thereby improving the applicability and functionality of the structure.
