Description

Technical Field

[0001] This invention relates to the field of auxiliary construction devices, and in particular to a device for offsetting exposed steel bars in concrete supports. Background Technology

[0002] Concrete bracing, also known as concrete support, refers to a structural form that combines concrete and steel reinforcement into one unit. It is used in engineering construction to support loads or restrict displacement. It is mainly used in subway tunnels, excavation projects, and other fields. It consists of concrete and steel reinforcement. Concrete is the main body of the supporting structure, while steel reinforcement is the skeleton of the concrete. Together, they transfer the load to the foundation.

[0003] Exposed reinforcing bars in concrete support structures are often displaced due to transportation or trampling during construction. This is especially true in precast assembly and precast composite construction processes, where the exposed reinforcing bars of the earlier constructed structure need to be aligned with the reinforcing bars of the later precast components. This often results in misalignment or collisions of the reinforcing bars, leading to a large number of out-of-sync exposed reinforcing bars and an uneven overall shape. When two concrete supports are staggered, the exposed reinforcing bars in the two support structures are not aligned, making it impossible to arrange the individual reinforcing bars. Currently, construction workers often use pry bars to correct the displaced exposed reinforcing bars. However, due to the difficulty in accurate positioning, correcting the displaced reinforcing bars is laborious and affects construction efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device for offsetting exposed steel bars in concrete supports. This device solves the problem that in existing technologies, manual correction of offset exposed steel bars using crowbars is difficult due to the inability to accurately position the bars, resulting in laborious correction and reduced construction efficiency.

[0005] According to an embodiment of the present invention, a device for offsetting exposed reinforcing bars in concrete supports, installed on the reinforcing bar body, includes:

[0006] Limiting plates, two limiting plates are arranged opposite each other to form an installation position for accommodating the steel bar body;

[0007] An offset rod, located in the installation position, has a rotatable mounting base. The mounting base is slidably positioned in the installation position and abuts against the bending point of the reinforcing bar. The offset rod is equipped with a limiting element that abuts against the reinforcing bar.

[0008] The locking assembly includes a movable block connected to the mounting base and a locking member disposed on the movable block. The limiting plate has several locking holes, and the locking member is used to fix the movable block in one of the locking holes so that the mounting base corresponds to the bending point of the reinforcing bar body.

[0009] Preferably, the locking element includes a mounting rod fixedly disposed on the movable block, two sliders slidably disposed on the mounting rod, a fixing frame disposed on the sliders, and a locking pin disposed on the fixing frame. When the slider slides along the axis of the mounting rod, the locking pin engages with or separates from the corresponding locking hole.

[0010] Preferably, the mounting rod sleeve is equipped with two pressure springs that abut against the two sliders respectively, and the ends of the pressure springs abut against the inner side of the moving block.

[0011] Preferably, a sliding sleeve and a mounting sleeve are sequentially fitted onto one end of the offset rod near the mounting base. A positioning groove is provided along the axis of the offset rod. The sliding sleeve is slidably engaged with the positioning groove. A limiting element is provided on the mounting sleeve. A torsion spring is provided between the mounting sleeve and the sliding sleeve.

[0012] Preferably, the limiting component is a limiting wheel, the mounting sleeve is fixedly provided with a fixing block, the limiting wheel is rotatably mounted on the fixing block, and the limiting wheel has an arc-shaped groove, in which the steel bar body is engaged.

[0013] Preferably, both limiting plates are provided with pedals on their sides, and the pedals are provided with several anti-slip textures.

[0014] Preferably, a washer is bolted to the side of the movable block near the steel bar body, and the washer has a groove, into which the steel bar body is engaged.

[0015] Preferably, the end of the offset rod away from the mounting base is provided with a handle.

[0016] Preferably, the inner side of the limiting plate is provided with a sliding groove, and the moving block is slidably engaged between the two sliding grooves.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this solution, two opposing limiting plates provide an installation position for correcting the offset of the rebar body, serving as initial positioning. Then, by moving the offset rod, the mounting base slides within the installation position until it reaches the bending point of the rebar body, providing stable support for the bending point. Finally, by actuating the offset rod, the limiting member compresses the bent section of the rebar body, shifting the bent section into the installation position, making it level with the straight section of the rebar body at the bottom of the mounting base, thus completing the offset correction of the rebar body. This method is more labor-saving and easier to operate than traditional pry bars.

[0019] In this solution, with the cooperation of the locking component, the moving block can drive the mounting base to slide within the mounting position. After sliding to the bending point of the steel bar body, the locking component can be engaged with the corresponding locking hole, thereby fixing the position of the moving block at the position of the locking hole. This ensures that the end of the offset rod is always aligned with the bending point of the steel bar body, thus ensuring the efficiency of the steel bar body offset correction.

[0026] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 3 As shown, this embodiment of the invention proposes a device for offsetting exposed reinforcing bars in concrete supports, which is installed on the reinforcing bar body 1 and includes:

[0028] Limiting plates 2, two limiting plates 2 are arranged opposite each other to form an installation position 4 for accommodating the steel bar body 1;

[0029] The offset rod 5 is located at the mounting position 4. The offset rod 5 is rotatably mounted on a mounting base 15. The mounting base 15 is slidably positioned at the mounting position 4 and abuts against the bending point of the reinforcing bar body 1. The offset rod 5 is equipped with a limiting member 6, which abuts against the reinforcing bar body 1.

[0030] The locking assembly includes a movable block 24 connected to the mounting base 15 and a locking member disposed on the movable block 24. The limiting plate 2 has a plurality of locking holes 20. The locking member is used to fix the movable block 24 in one of the locking holes 20 so that the mounting base 15 corresponds to the bending point of the reinforcing bar body 1.

[0031] In this embodiment of the invention, two limiting plates 2 are arranged opposite to each other and connected to each other. The gap between them provides an installation position 4 for the offset correction of the rebar body 1, which plays a preliminary positioning role. Then, by moving the offset rod 5, it drives the mounting seat 15 to slide within the installation position 4 until the mounting seat 15 moves to the bending point of the rebar body 1, thereby providing stable support for the bending point of the rebar body 1. When the rebar body 1 is offset corrected, by turning the offset rod 5, the end of the offset rod 5 rotates around the mounting seat 15 as the axis, thereby causing the limiting member 6 to make a circular motion around the mounting seat 15 as the axis. When the rebar body 1 is offset corrected, it is located between the limiting member 6 and the mounting seat 15. The movement of the limiting member 6 can squeeze the bending section of the rebar body 1, thereby offsetting the bending section of the rebar body 1 into the installation position 4, keeping it horizontal with the straight section of the rebar body 1 at the bottom of the mounting seat 15, thus completing the offset correction of the rebar body 1. Compared with the traditional pry bar, this method is more labor-saving and easier to operate.

[0032] Secondly, to ensure the stability of the mounting base 15 after it moves within the mounting position 4, with the cooperation of the locking component, the mounting base 15 can be slid within the mounting position 4 by the moving block 24. After sliding to the bending point of the rebar body 1, the locking component can be engaged with the corresponding locking hole 20, thereby fixing the position of the moving block 24 at the position of the locking hole 20. This ensures that the end of the offset rod 5 is always aligned with the bending point of the rebar body 1, ensuring the stability of the offset correction of the rebar body 1 and thus improving efficiency. At the same time, several locking holes 20 are arranged in an array along the height direction of the limiting plate 2. The mounting base 15 can be fixed in different locking holes 20 by the locking component to control the different positions of the mounting base 15 within the mounting position 4. This is applicable to rebar bodies 1 at different bending positions, conveniently addressing different offset forms of exposed rebars in concrete supports, and improving convenience.

[0033] Based on the above solutions, such as Figure 3 and Figure 4As shown, the locking component includes a mounting rod 14 fixedly mounted on the movable block 24, two sliders 13 slidably mounted on the mounting rod 14, a fixing frame 11 mounted on the sliders 13, and a locking pin 10 mounted on the fixing frame 11. When the sliders 13 slide along the axis of the mounting rod 14, the locking pin 10 engages with or separates from the corresponding locking hole 20. Specifically, when the position of the movable block 24 is controlled by the locking component, the movable block 24 can slide freely within the mounting position 4 in the initial state. When the movable block 24 slides to the designated position, the sliders 13 are slid inward towards the inside of the movable block 24, causing the sliders 13 to drive the fixing frame 11 to gradually move towards the side of the movable block 24. This causes the locking pin 10 on the fixing frame 11 to gradually engage with the corresponding locking hole 20, quickly completing the limitation of the movable block 24, preventing the movable block 24 from moving within the mounting position 4, thus ensuring the stability of the offset rod 5 when correcting the offset of the reinforcing bar body 1. To ensure the strength of the movable block 24, two sliders 13 are arranged radially inside the movable block 24, and a fixing frame 11 and a locking pin 10 are respectively provided, which increases the contact area with the limiting plate 2, ensures strength, and improves service life.

[0034] Secondly, such as Figure 2 As shown, the mounting rod 14 is fitted with two pressure springs 12 that abut against the two sliders 13 respectively. The ends of the pressure springs 12 abut against the inner side of the moving block 24. The pressure springs 12 can give the two fixing brackets 11 an initial position. Under the pressure of the pressure springs 12, the sliders 13 are always in a position close to the moving block 24. When adjusting the position of the moving block 24, the fixing brackets 11 need to be pushed so that the sliders 13 slide in the moving block 24 and squeeze the pressure springs 12 to deform them. When the moving block 24 slides to the designated locking hole 20, the fixing brackets 11 can be released directly, so that it resets under the action of the pressure springs 12 and automatically allows the locking pins 10 to engage in the locking holes 20, completing the fixation. After fixation, under the action of the pressure springs 12, the locking pins 10 are always kept in the locking holes 20, which indirectly ensures stability.

[0035] Based on the above solutions, such as Figure 2 and Figure 4As shown, a sliding sleeve 9 and a mounting sleeve 7 are sequentially fitted onto one end of the offset rod 5 near the mounting base 15. A positioning groove 21 is provided along the axis of the offset rod 5. The sliding sleeve 9 is slidably engaged with the positioning groove 21. A limiting member 6 is provided on the mounting sleeve 7. A torsion spring 8 is provided between the mounting sleeve 7 and the sliding sleeve 9. Because the bending points of the steel reinforcement body 1 on the concrete support are different, in order to facilitate the easy entry of the steel reinforcement body 1 into the space between the mounting base 15 and the limiting member 6, in the initial stage of installation of the steel reinforcement body 1, the sliding sleeve 9 is slid upward and the limiting member 6 is rotated so that the limiting member 6 rotates to one side of the offset rod 5 and the torsion spring 8 is deformed. Then, the two limiting plates 2 are engaged in the steel reinforcement body 1. The limiting member 6 can be released directly, so that the limiting member 6 is driven back to its original position under the action of the torsion spring 8. This allows the steel reinforcement body 1 to enter between the limiting member 6 and the mounting base 15 for subsequent offset correction work. Furthermore, the sliding sleeve 9 can drive the limiting member 6 to the top of the offset rod 5. When the bending point of the steel reinforcement body 1 is at its bottom, the sliding sleeve 9 is first slid to the top of the offset rod 5, and then the offset rod 5 is controlled to be parallel with the steel reinforcement body 1. Finally, the sliding sleeve 9 is released directly to allow the limiting member 6 to move to the bending point of the steel reinforcement body 1. This method can be applied to steel reinforcement bodies 1 without bending points, making it convenient to use.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, the limiting component 6 is a limiting wheel, and the mounting sleeve 7 is fixedly provided with a fixing block 23. The limiting wheel is rotatably mounted on the fixing block 23, and the limiting wheel has an arc-shaped groove 18. The reinforcing bar body 1 is engaged in the arc-shaped groove 18. By using a rotatable limiting wheel mounted on the fixing block 23, when the reinforcing bar body 1 is offset and corrected by the limiting wheel, the limiting wheel can rotate on the reinforcing bar body 1, thereby reducing the friction on the reinforcing bar body 1, ensuring the quality of the reinforcing bar body 1 after offset correction, ensuring the structural stability of the reinforcing bar body 1 after reinforcement, and under the action of the arc-shaped groove 18, the limiting wheel fits the shape of the reinforcing bar body 1 more closely, improving efficiency.

[0037] Specifically, such as Figure 1 As shown, both limiting plates 2 are equipped with pedals 3 on their sides. The pedals 3 have several anti-slip textures. When the offset rod 5 is subjected to force to correct the offset of the steel bar body 1, the construction personnel can step on the pedals 3 to ensure the stability of the limiting plate 2 under the concrete support and to better apply force to the offset rod 5.

[0038] Specifically, such as Figure 4As shown, a washer 16 is bolted to the side of the movable block 24 near the rebar body 1. The washer 16 has a groove 17, and the rebar body 1 is engaged in the groove 17. When the rebar body 1 is offset and corrected, the movable block 24 is subjected to a large force from the rebar body 1. Under the action of the washer 16, the wear of the rebar body 1 on the movable block 24 can be reduced, thereby improving its service life. The washer 16 is fixedly installed on the movable block 24 by bolts. When the washer 16 is severely worn, it can be replaced automatically. At the same time, under the action of the groove 17, it can provide a limiting function for the rebar body 1.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the end of the offset rod 5 away from the mounting base 15 is provided with a handle 19. The handle 19 allows construction personnel to easily operate the offset rod 5. The handle 19 is also provided with anti-slip texture to increase friction with the palm and ensure stability.

[0040] Specifically, such as Figure 2 As shown, a groove 22 is provided on the inner side of the limiting plate 2. The moving block 24 is slidably engaged between the two grooves 22. Under the action of the groove 22, the moving block 24 can be limited by the groove 22, so that the lateral force on the moving block 24 can be borne by the groove 22, reducing the force on the locking pin 10 and ensuring the structural stability of each component in the locking part.

[0041] In summary, this solution can use the limiting plate 2 to provide initial positioning for the rebar body 1 that needs offset correction, and move the offset rod 5 to move the mounting base 15 to the bending point of the rebar body 1, providing support for the subsequent bending of the rebar body 1. Under the action of the locking pin 10, the moving block 24 can be stably fixed on the limiting plate 2. Furthermore, the mounting base 15 can be moved to various positions on the limiting plate 2, thereby enabling offset correction of different bending points of the rebar body 1. This solution is suitable for different rebar situations, and can not only be used for offset correction of the rebar body 1, but also for bending the rebar body 1 to the required angle, satisfying various rebar layout requirements.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
