Description

Technical Field

[0001] This utility model relates to the field of steel bar welding equipment technology, specifically to a small and convenient steel bar welding positioning device. Background Technology

[0002] In building construction, steel bar welding is a core component ensuring structural strength and stability, and it is widely used in various fields such as housing construction, bridge engineering, and municipal facilities. The quality of steel bar welding directly depends on the positioning accuracy of the steel bars during the welding process. If the positioning deviation is too large, it can easily lead to uneven stress distribution and stress concentration in the welded joint, which may even cause structural safety hazards in severe cases. In traditional rebar welding operations, manual positioning or simple tools are often used for assistance. Manual positioning requires multiple people working together, resulting in low efficiency. Furthermore, it's difficult to ensure the rebar's axis is aligned and the angle is precise. Problems such as the bent ends of the rebar not being on the same plane after welding, and misalignment at the longitudinal joint, frequently occur, leading to decreased joint mechanical properties and a rework rate exceeding 30%, severely hindering construction progress. At the same time, the stability of manual operation is greatly affected by the operator's experience and physical strength, resulting in significant quality fluctuations. While existing rebar positioning clamps have improved upon the shortcomings of manual positioning to some extent, they still have many limitations: First, most clamps are designed with fixed dimensions and can only accommodate rebars of specific diameters (such as 10-16mm or 20-25mm). In the face of the common scenario of using multiple specifications of rebars in engineering, clamps need to be changed frequently, making the operation cumbersome. Second, some positioning devices are bulky and complex in structure, taking time to assemble and disassemble, and are difficult to use flexibly in narrow working spaces (such as bridge abutments and beam-column joints). Third, the fastening mechanism of traditional clamps mostly uses buckles or bolts to apply pressure directly, which can easily cause the rebars to slip due to uneven force, affecting the positioning accuracy. Especially when welding skeleton components, the synchronous positioning of multiple rebars is extremely difficult. Furthermore, the lack of versatility of existing equipment is also reflected in its limited functionality. Most positioning devices can only achieve the butt joint positioning of a single rebar, failing to meet the multi-point synchronous welding requirements of rebar skeletons (such as rebar cages and lattice columns). This necessitates the additional equipment, increasing construction costs. Additionally, traditional devices are mostly made of ordinary steel, which is prone to deformation due to high welding temperatures or external impacts during long-term use, shortening its service life and further increasing engineering maintenance costs. Summary of the Invention

[0003] The purpose of this utility model is to provide a small and convenient rebar welding positioning device to solve the problem that although the existing rebar positioning clamps mentioned in the background art have improved the defects of manual positioning to a certain extent, they still have many limitations: First, most clamps are designed with fixed size and can only be used for rebars of specific diameters (such as 10-16mm or 20-25mm). In the face of the common scenario of using multiple specifications of rebars in engineering, the clamps need to be changed frequently, which is cumbersome.

[0004] To achieve the above objectives, this utility model provides a small and convenient rebar welding positioning device, including a welding positioning device base, a welding positioning device push-fastener, a welding positioning device rebar anti-slip pad, a welding positioning device push-fastener control screw, and a welding positioning device control screw rotation handle. Each component is detachable and, after assembly, can be used for positioning welding of rebars or rebar cages. The welding positioning device base is provided with a welding device fixing slot, a fastener control screw limit control screw hole, a rear baffle anti-slip pad mounting screw hole, a push-fastener mounting slot, and a rear baffle. The device can be fixed in place at the site via the welding device fixing slot for general welding operations.

[0005] This device consists of a welding positioning device base, a jacking fastener, a rebar anti-slip pad, a jacking fastening control screw, and a control screw rotation handle. All components are detachable, and the welding device fixing slot on the base secures the device. Through the coordinated operation of these components, the positioning welding of the rebar or rebar cage is completed.

[0006] Preferably, the welding positioning device has a push fastener with a pusher anti-slip pad mounting screw hole, a control screw connecting screw hole, and a push fastener limit slot.

[0007] This feature includes mounting screw holes for the anti-slip pad, connecting screw holes for the control screw, and limiting slots for the pusher fastener on the pusher fastener. These are used to install the anti-slip pad, connect the control screw, and limit the movement of the pusher fastener, respectively.

[0008] Preferably, the anti-slip pad of the welding positioning device is provided with anti-slip pad mounting screw holes.

[0009] This feature includes mounting screw holes on the anti-slip pads for attaching the anti-slip pads to the base and the push-pull fastener.

[0010] Preferably, the welding positioning device has a rotating handle connection hole on the push-tightening control screw that is connected to the rotating handle of the welding positioning device control screw.

[0011] This feature includes a rotating handle connection hole on the push-fastening control screw, which connects to the control screw's rotating handle, allowing for a detachable connection between the two.

[0012] Preferably, the anti-slip pad of the welding positioning device is made of wear-resistant metal with anti-slip texture on the surface. It is bolted to the anti-slip pad of the rear baffle and the anti-slip pad of the pusher through the mounting screw holes of the anti-slip pad, respectively, to enhance the friction when the steel bar is tightened.

[0013] This feature includes a steel reinforcement anti-slip pad made of wear-resistant metal with anti-slip texture. It is connected to the base and the push-up fastener via screw holes, and the anti-slip texture increases the friction with the steel reinforcement.

[0014] Preferably, the rear baffle and the base of the welding positioning device are integrated into one structure. The inner sidewall of the rear baffle is opposite to the inner sidewall of the push fastener of the welding positioning device, and the distance between the two can be adjusted by the push fastening control screw of the welding positioning device to accommodate steel bars with a diameter of 5-30mm.

[0015] This design features a backplate and base that are integrated into a single structure, positioned opposite the inner wall of the push-fastener. The distance between them can be adjusted by controlling the screw to accommodate steel bars of different diameters.

[0016] Preferably, the jacking fastener limiting slot is adapted to the jacking fastener mounting slot, and the jacking fastener limiting slot slides along the length direction of the jacking fastener mounting slot to limit the movement trajectory of the jacking fastener of the welding positioning device.

[0017] This setting allows the push-pull fastener limit slot to match the push-pull fastener mounting slot on the base. The limit slot slides along the length of the mounting slot, restricting the movement trajectory of the push-pull fastener.

[0018] Preferably, the control screw rotation handle of the welding positioning device has a T-shaped structure, and is detachably connected to the welding positioning device push-and-tighten control screw through the rotation handle connection hole. The gripping end of the rotation handle is covered with a rubber anti-slip sleeve.

[0019] This setting features a T-shaped control screw rotation handle that is detachably connected to the control screw via a connection hole. The grip end is fitted with a rubber anti-slip sleeve. The T-shaped structure facilitates the application of force, and the rubber sleeve increases friction.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this small, portable rebar welding positioning device, regarding positioning accuracy, the device effectively ensures the axial alignment and planar consistency of the rebar during longitudinal butt welding or bending by using the relative arrangement of the rear baffle and the jacking fastener, along with the precise adjustment of the jacking fastening control screw. This significantly reduces stress concentration problems caused by positioning deviations. Simultaneously, the rebar anti-slip pad of the welding positioning device is made of wear-resistant metal with anti-slip textures, enhancing the friction during rebar fastening and preventing slippage due to vibration during welding. This results in higher positioning accuracy, significantly improved mechanical properties of the welded joint, and reduced rework rates. In terms of ease of operation, each component adopts a detachable design, and the assembly steps are simple and clear, allowing for quick installation without complicated tools, significantly shortening the device preparation time. The T-shaped control screw rotation handle has a rubber anti-slip sleeve on the gripping end, which not only facilitates the operator's application of force but also improves the comfort and stability of operation. By rotating the handle to drive the jacking and tightening control screw, the jacking and tightening device can be easily pushed forward and backward, completing the tightening and loosening of the reinforcing bars. A single person can complete the positioning operation, reducing manual coordination costs and improving construction efficiency. In terms of adaptability, the distance between the rear baffle and the jacking fastener can be flexibly adjusted by the jacking fastening control screw, which can adapt to various specifications of steel bars with diameters of 5-30mm, meet the welding positioning needs of different types of steel bars in the project, and eliminate the need to frequently replace the positioning device, greatly enhancing the applicability of the equipment in complex construction scenarios. In terms of versatility and flexibility, the device is small in size, lightweight, and compact in structure, making it easy to carry and use flexibly in confined working spaces. The device can be fixed to the site using the welding device's fixing slots for general welding operations; simultaneously, the device can be used alone to position a single rebar, or in combination with a positioning rebar skeleton to achieve multi-point synchronous welding, meeting diverse positioning needs in different construction scenarios and improving the overall utilization rate of the equipment. In terms of economy and durability, the entire device is made of durable materials such as high-strength alloys. The matching design of the jacking fastener limit slot and the jacking fastener mounting slot ensures the stability of component movement, reduces component wear caused by structural shaking, and extends the service life of the device. In addition, the device's versatility reduces the need for positioning fixtures of various specifications, reducing equipment procurement costs; the improved operating efficiency and reduced rework rate also indirectly save construction time and labor costs, demonstrating good economic practicality.
