Description

Technical Field

[0001] This utility model relates to the field of rebar clamp technology, and in particular to a rebar binding and positioning clamp with adjustable position. Background Technology

[0002] In the field of building construction, the binding of structural steel bars is a crucial process. Currently, in practice, to ensure that the spacing of the steel bars meets the design requirements, the common practice is for on-site workers to weld steel bars to create clamps at fixed intervals before binding. During the subsequent binding process, workers bind the steel bars according to the spacing of these clamps, thereby ensuring the relative regularity of the steel bar arrangement. This plays a fundamental role in controlling construction quality to a certain extent, and this method is widely used in the early preparation stage of steel bar construction for various building structures.

[0003] However, the existing method of welding fixed-spacing clamps has significant drawbacks. The primary problem is that once the clamps are welded, the spacing between the reinforcing bars is fixed, making it impossible to flexibly adjust them according to specific circumstances or design changes during construction. For example, when encountering areas with dense reinforcing bars that require fine-tuning the spacing to avoid conflicts, or when adjusting the overall reinforcing bar layout due to measurement errors, the welded clamps are unsuitable, forcing workers to re-cut and re-weld the clamps, greatly increasing the complexity and time cost of the process. Secondly, because the clamp spacing is determined by welding, the finished positioning clamps can only meet the spacing requirements for a single use, becoming useless after the project is completed. This results in a waste of building materials, contradicts the modern construction concepts of green construction and resource conservation, and also places a certain economic burden on the construction party. These problems urgently need to be addressed. Utility Model Content

[0004] In view of this, an embodiment of the present invention provides a rebar binding and positioning clamp with adjustable position.

[0005] An embodiment of this utility model provides a position-adjustable rebar tying and positioning clamp, comprising:

[0006] A horizontal tube fitting has a groove on its exterior that communicates with its internal cavity;

[0007] Multiple clamping ribs are slidably disposed on the outside of the horizontal pipe fitting, and each clamping rib faces the same direction, and each clamping rib is restricted from rotating relative to the horizontal pipe fitting;

[0008] And a self-aligning rod, which is disposed in the inner cavity of the horizontal tube, and multiple adjustment grooves are provided on the outer wall of the self-aligning rod. Each of the clamping ribs is provided with a sliding rod that passes through the horizontal tube. The multiple sliding rods are slidably connected to the sliding grooves. Each sliding rod is slidably connected to one of the adjustment grooves. The multiple adjustment grooves are spiral grooves that are equally spaced on the outside of the self-aligning rod, and the spiral arc of adjacent adjustment grooves increases proportionally. By rotating the self-aligning rod, the multiple sliding rods are driven to move, and the movement distance of the multiple sliding rods gradually increases.

[0009] Furthermore, the horizontal tube includes multiple continuously connected round tubes and square tubes, and the groove is formed along the length of the square tube;

[0010] The clamping reinforcement includes a sliding sleeve and a vertical reinforcement, with the sliding sleeve sliding on the outside of the square tube.

[0011] Furthermore, one end of the slide rod is connected to the inner wall of the sliding sleeve, and the other end is slidably connected to the adjusting groove.

[0012] Furthermore, the end of the slide bar that slides relative to the adjusting groove is hemispherical.

[0013] Furthermore, one end of the horizontal tube is also provided with a rotating rod, which is used to drive the self-aligning rod to rotate. The rotating rod includes a hexagonal head, a connecting rod, and a bearing. One end of the connecting rod is connected to the hexagonal head, and the bearing is connected to the connecting rod.

[0014] Both ends of the self-aligning rod are provided with first hexagonal countersunk holes, and the hexagonal head is inserted into the first hexagonal countersunk holes so that the rotation of the rotating rod can drive the self-aligning rod to rotate.

[0015] Furthermore, the outer ring of the bearing is provided with an elastic sleeve, the inner ring of the bearing is connected to the connecting rod, and the inner diameter of the elastic sleeve is larger than that of the round tube.

[0016] Furthermore, a second hexagonal countersunk hole is provided on the end of the connecting rod away from the hexagonal head.

[0017] Furthermore, an end cap is fastened to the outside of the bearing.

[0018] Furthermore, both the round tube and the square tube have a circular hole extending through them along their length. The circular hole has the same size as the self-aligning rod, and the self-aligning rod is rotatably connected to the circular hole.

[0019] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The position-adjustable rebar tying positioning clamp of this utility model drives the sliding rod to move through the rotation of the self-aligning rod, thereby causing the clamp bar to slide on the horizontal pipe. It can quickly and accurately adjust the position of the clamp bar, greatly improving the positioning efficiency of rebar tying. Secondly, the setting of the spiral arc of adjacent adjustment grooves increasing proportionally makes the movement distance of multiple sliding rods gradually increase, which can be flexibly adapted according to rebars of different specifications and layouts to meet diverse construction needs and enhance the versatility and applicability of the clamp. The hexagonal head of the rotating rod is inserted into the first hexagonal countersunk hole on the self-aligning rod. With the use of bearings, the rotation operation is more labor-saving and stable. The setting of the elastic sleeve also further improves the comfort and safety of operation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0030] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0031] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please refer to Figure 1 An embodiment of this utility model provides a position-adjustable rebar binding and positioning clamp, including a horizontal pipe, multiple clamp bars, and a self-aligning rod 6.

[0033] The horizontal tube is composed of multiple continuously connected round tubes 1 and square tubes 2. The sliding groove 21 is opened in the length direction of the square tube 2. The clamping rib includes a sliding sleeve 3 and a vertical rib 4. The sliding sleeve 3 is slidably sleeved on the outside of the square tube 2. This arrangement restricts the relative rotation of the clamping rib while it slides relative to the horizontal tube. This ensures that the orientation of multiple clamping ribs remains consistent when the relative spacing is adjusted.

[0034] Please refer to Figure 4In this embodiment, each clamp is provided with a sliding rod 8 that penetrates the square tube 2. One end of the sliding rod 8 is connected to the inner wall of the sliding sleeve 3, and the other end is slidably connected to the adjusting groove 7. The end of the sliding rod 8 that slides relative to the adjusting groove 7 is hemispherical, which can reduce the frictional resistance during sliding and make the sliding rod 8 slide more smoothly in the adjusting groove 7.

[0035] Please refer to Figure 3 and Figure 4 The self-aligning rod 6 is installed in the inner cavity of the horizontal tube fitting. Its outer wall is covered with multiple adjustment grooves 7. These adjustment grooves 7 are distributed in a spiral shape at equal distances. The spiral curvature of adjacent adjustment grooves 7 increases in a certain proportion. The slide rod 8 passes through the horizontal tube fitting and is slidably connected to the slide groove 21, and is also slidably connected to the corresponding adjustment groove 7.

[0036] With this design, when the self-aligning rod 6 rotates, the spiral shape of the adjusting groove 7 will drive the slide rod 8, forcing the slide rod 8 to move. At the same time, since the spiral arc of adjacent adjusting grooves 7 increases proportionally, the movement distance of multiple consecutive slide rods 8 gradually increases, thereby realizing the adjustment of the relative spacing of the clamping ribs.

[0037] In a specific implementation, one end of the adjustable groove 7 can be optionally set as a variable pitch spiral groove with a pitch of 50mm and 60mm, and the other adjustable groove 7 close to the adjustable groove 7 can be a variable pitch spiral groove with a pitch of 58mm and 68mm. The two slide rods 8 are slidably connected to the two adjustable grooves 7 respectively.

[0038] When the self-aligning rod 6 rotates one full turn, it rotates 360 degrees. For one slide rod 8, its movement distance in the adjustment groove 7 is 376.99 mm, and the movement distance of the other slide rod 8 in the adjustment groove 7 is 427.29 mm. There is a distance difference of 50.30 mm between the two slide rods 8, which can be understood as the distance between the two slide rods 8 being increased by 50.30 mm.

[0039] In an optional embodiment, in order to facilitate the rotation of the self-aligning rod 6, a rotating rod 5 is provided at one end of the horizontal tube. The rotating rod 5 includes a hexagonal head 53, a connecting rod 52 and a bearing 51, wherein one end of the connecting rod 52 is fixedly connected to the hexagonal head 53, and the bearing 51 is mounted on the connecting rod 52 to ensure stability during rotation.

[0040] Both ends of the self-aligning rod 6 are machined with first hexagonal countersunk holes 9. The hexagonal head 53 is inserted into the first hexagonal countersunk hole 9. When the rotating rod 5 is rotated, the hexagonal head 53 on it drives the self-aligning rod 6 to rotate, thereby realizing the adjustment of the position of the clamping bar.

[0041] To facilitate the installation of the rotating rod 5, an elastic sleeve 12 is provided on the outer ring of the bearing 51. The elastic sleeve 12 can be a sponge sleeve or a rubber sleeve. The inner diameter of the elastic sleeve 12 is slightly larger than the outer diameter of the round tube 1. This ensures the connection stability between the rotating rod 5 and the round tube 1, and also provides a certain preload force by utilizing the elasticity of the elastic sleeve 12, which facilitates the installation and disassembly of the rotating rod 5.

[0042] Meanwhile, a second hexagonal countersunk hole 10 is provided on the end of the connecting rod 52 away from the hexagonal head 53, which facilitates its use with other tools when needed, further enhancing its functionality.

[0043] In an optional embodiment, an end cap 11 is also fastened to the outside of the bearing 51 to protect the bearing 51 and prevent dust, debris and other contaminants from entering the bearing 51 and affecting its normal operation and service life.

[0044] Both the round tube 1 and the square tube 2 have circular holes running through them along their length. The size of these holes matches that of the self-aligning rod 6. The self-aligning rod 6 is connected to the circular holes by a rotating method to ensure that the self-aligning rod 6 can rotate freely in the inner cavity of the horizontal tube while maintaining the stability of the overall structure.

[0045] In practical use, the clamp is placed at the location where the rebar needs to be tied. According to the layout and size requirements of the rebar, the rotating rod 5 drives the self-aligning rod 6 to rotate. As the self-aligning rod 6 rotates, the adjusting groove 7 drives the sliding rod 8 to move, thereby causing the sliding sleeve 3 to slide along the sliding groove 21 of the square tube 2, adjusting the position of the vertical bars 4. This allows the spacing between multiple vertical bars 4 to be adjusted to meet the tying requirements of rebars with different spacings. Once the appropriate position is reached, the rotation is stopped, and the rebar tying operation can be carried out. If further adjustment is needed, the above rotation operation can be repeated. The operation is simple and quick, effectively improving the positioning efficiency and accuracy of rebar tying.

[0046] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0047] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
