Description

Technical Field

[0001] This invention belongs to the field of building construction equipment technology, and more specifically, it relates to a rebar spacing monitoring and holding device. Background Technology

[0002] In the construction process, steel reinforcement fabrication and concrete pouring are often required. During the installation of steel reinforcement structures, it's crucial to maintain the spacing of the reinforcement bars within a suitable range according to the design plan. Sometimes, standardized steel reinforcement spacing retainers are used to maintain this spacing. The method involves placing the reinforcement bars in the notches of the retainer, securing them with binding wire, and finally removing the retainer. However, in some projects, after removing the retainers and during subsequent construction, steel reinforcement displacement often occurs, causing some bars to exceed the standard spacing. Currently, it can only be speculated that this phenomenon is caused by differences in the binding techniques used by different steelworkers and varying stress levels on the reinforcement bars in different locations. Because the cause, mechanism, and patterns of change are unclear, it is difficult to develop effective measures to solve this problem.

[0003] Therefore, it is necessary to provide a rebar spacing maintainer that can monitor the changes in rebar spacing in real time, so as to study the stress change law during rebar installation and subsequent work. Summary of the Invention

[0004] The purpose of this invention is to provide a rebar spacing monitoring and retention device to solve the technical problem of lack of rebar spacing monitoring in the existing technology during rebar installation and subsequent construction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rebar spacing monitoring and holding device is provided, comprising a first vertical plate, a second vertical plate, a threaded sleeve, a rotating rod, a threaded block, and two clamping and fixing mechanisms. The second vertical plate is disposed on one side of the first vertical plate; the threaded sleeve is fixedly disposed on one side of the second vertical plate; the rotating rod is rotatably disposed on one side of the first vertical plate, one end of the rotating rod extending into the interior of the threaded sleeve and having the freedom of elastic expansion and contraction along the axial direction; the threaded block is fixedly disposed at one end of the rotating rod, and the threaded block is threadedly connected to the inner wall of the threaded sleeve; the two clamping and fixing mechanisms are respectively disposed on the sides of the first and second vertical plates that are far apart from each other, and the two clamping and fixing mechanisms are used to clamp and fix two adjacent rebar segments; a distance measuring component is disposed on the second vertical plate and faces the first vertical plate to monitor the distance between the second vertical plate and the first vertical plate in real time.

[0006] In one possible implementation, based on the above technical solutions, a sliding sleeve is fixedly provided on one side of the second vertical plate, and the sliding sleeve is arranged parallel to the threaded sleeve. A sliding rod is fixedly provided on one side of the first vertical plate, and the sliding rod is arranged parallel to the rotating rod. The sliding rod is slidably connected to the sliding sleeve.

[0007] In one possible implementation, based on the above technical solutions, the end of the rotating rod located inside the threaded sleeve is provided with an elastic element, which is connected to the threaded block.

[0008] In one possible implementation, based on the above technical solutions, the elastic element includes an end slide rod, a spring, and a rubber sleeve. The end slide rod has a non-circular cross-section. The threaded block has a sliding hole that slides with the end slide rod. The threaded block and the spring are both sleeved on the end slide rod, and the two ends of the spring are fixedly connected to the rotating rod and the threaded block, respectively. The rubber sleeve is sleeved on the outside of the spring and has an interference fit with the inner wall of the threaded sleeve.

[0009] In one possible implementation, based on the above technical solutions, a first knob is fixedly mounted on the rotating rod.

[0010] In one possible implementation, based on the above technical solutions, multiple side plates are fixedly provided on the side of the first vertical plate and the second vertical plate that are far apart from each other. The clamping and fixing mechanism includes a bidirectional screw, multiple limiting rods, two sliding plates and two arc-shaped clamping plates. The bidirectional screw is rotatably disposed on the side of the two side plates that are close to each other. The multiple limiting rods are fixedly disposed on the side of the two side plates that are close to each other. The two sliding plates are threaded onto the bidirectional screw and are slidably connected to the multiple limiting rods. The two arc-shaped clamping plates are respectively fixedly disposed on one side of the two sliding plates.

[0011] In one possible implementation, based on the above technical solutions, a second knob is fixedly provided at the top of the bidirectional screw, and an installation groove is provided on one side of the second vertical plate, with a groove cover provided on the installation groove.

[0012] In one possible implementation, based on the above technical solutions, the ranging component includes a laser ranging sensor, a data processing module, and a power supply module. The laser ranging sensor is located on one side of the second vertical plate, which has a mounting slot. The data processing module and the power supply module are both located in the mounting slot. The data processing module is electrically connected to the laser ranging sensor and the power supply module, respectively. The data processing module has a data storage unit and a data transmission unit.

[0013] In one possible implementation, in conjunction with the above technical solutions, the ranging component also includes a display screen and a charging interface. The power module is a lithium battery, which is electrically connected to the charging interface, and the display screen is electrically connected to the data processing module.

[0014] In one possible implementation, based on the above technical solutions, the rebar spacing monitoring and holding device also includes an outer cover box and a lock. The first vertical plate, the second vertical plate, the threaded sleeve, the rotating rod, the threaded block, and the two clamping and fixing mechanisms are all located inside the outer cover box. The lock is located on the outer cover box and is used to lock the outer cover box.

[0015] The beneficial effects of the rebar spacing monitoring and holding device provided by this invention are as follows: Compared with the prior art, in use, this invention first utilizes the cooperation of the threaded sleeve, rotating rod, and threaded block, and adjusts the distance between the two clamping and fixing mechanisms to a suitable position by reading the distance measurement component. Then, the two clamping and fixing mechanisms clamp and fix two rebars respectively. During the rebar binding and subsequent construction process, the reading changes of the distance measurement component are continuously read and recorded until the concrete is poured and the two clamping and fixing mechanisms are removed to complete the monitoring. Because the rotating rod has the freedom of elastic extension and contraction along the axial direction, if relative displacement occurs between the two clamped and fixed rebars during the rebar binding and subsequent construction process, the rotating rod will be slightly stretched or compressed. At this time, while ensuring the rebar spacing, the trend of rebar displacement can be obtained, thus enabling a more accurate determination of which construction stage caused the rebar displacement, providing a basis for formulating more effective prevention and control measures. Simultaneously, the rotating rod's freedom of elastic extension and contraction along the axial direction also plays a certain buffering role, reducing the impact on the threaded structure between the threaded block and the threaded sleeve, decreasing the displacement between the threaded block and the threaded sleeve, and improving the reliability of use.

[0024] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] It should be further noted that the accompanying drawings and embodiments of the present invention mainly describe the concept of the present invention. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0026] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0027] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0028] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0030] The rebar spacing monitoring and holding device provided by the present invention will now be described.

[0031] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a rebar spacing monitoring and holding device, including a first vertical plate 1, a second vertical plate 2, a threaded sleeve 3, a rotating rod 4, a threaded block 5, and two clamping and fixing mechanisms. The second vertical plate 2 is disposed on one side of the first vertical plate 1; the threaded sleeve 3 is fixedly disposed on one side of the second vertical plate 2; the rotating rod 4 is rotatably disposed on one side of the first vertical plate 1, one end of the rotating rod 4 extends into the interior of the threaded sleeve 3 and has the freedom of elastic expansion and contraction along the axial direction; the threaded block 5 is fixedly disposed on one end of the rotating rod 4 and is threadedly connected to the inner wall of the threaded sleeve 3; the two clamping and fixing mechanisms are respectively disposed on the sides of the first vertical plate 1 and the second vertical plate 2 that are far apart from each other, and the two clamping and fixing mechanisms are used to clamp and fix two adjacent rebar segments; the distance measuring component is disposed on the second vertical plate 2 and faces the first vertical plate 1 to monitor the distance between the second vertical plate 2 and the first vertical plate 1 in real time.

[0032] Compared with the prior art, the rebar spacing monitoring and holding device provided in this embodiment, during use, first utilizes the cooperation of the threaded sleeve 3, rotating rod 4, and threaded block 5, and adjusts the distance between the two clamping and fixing mechanisms to a suitable position by reading the distance measuring component. Then, the two clamping and fixing mechanisms clamp and fix two rebars respectively. Subsequently, during the rebar binding and subsequent construction process, the reading changes of the distance measuring component are continuously read and recorded until the concrete is poured and the two clamping and fixing mechanisms are removed to complete the monitoring. Since the rotating rod 4 has the freedom of elastic extension and contraction along the axial direction, if relative displacement occurs between the two clamped and fixed rebars during the rebar binding and subsequent construction process, the rotating rod 4 will be slightly stretched or slightly compressed. At this time, while ensuring the rebar spacing, the trend of rebar displacement can be obtained, thus enabling a more accurate determination of which construction stage caused the rebar displacement, providing a basis for formulating more effective prevention and control measures. At the same time, the elastic extension and contraction of the rotating rod 4 along the axial direction also plays a certain buffering role, so that the thread structure between the threaded block 5 and the threaded sleeve 3 is subjected to less impact, reducing the displacement between the threaded block 5 and the threaded sleeve 3, and improving the reliability of use.

[0033] like Figures 1 to 5 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0034] like Figures 1 to 3 As shown, a sliding sleeve 6 is fixedly provided on one side of the second vertical plate 2. The sliding sleeve 6 is arranged parallel to the threaded sleeve 3. A sliding rod 7 is fixedly provided on one side of the first vertical plate 1. The sliding rod 7 is arranged parallel to the rotating rod 4. The sliding rod 7 is slidably connected to the sliding sleeve 6 to enhance the bending resistance between the rotating rod 4 and the threaded sleeve 3.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, one end of the rotating rod 4 located inside the threaded sleeve 3 is provided with an elastic element, which is connected to the threaded block 5 to realize the elastic extension and retraction of the rotating rod 4 along the axial direction.

[0036] The elastic element includes an end slide rod 22, a spring 23, and a rubber sleeve 24. The end slide rod 22 has a non-circular cross-section. The threaded block 5 has a sliding hole that slides with the end slide rod 22. Both the threaded block 5 and the spring 23 are sleeved on the end slide rod 22, and the two ends of the spring 23 are fixedly connected to the rotating rod 4 and the threaded block 5, respectively. The rubber sleeve 24 is sleeved on the outside of the spring 23 and is interference-fitted with the inner wall of the threaded sleeve 3. This allows the elastic element to provide elastic expansion and contraction along the axial direction of the rotating rod 4 without rotation. Furthermore, the rubber sleeve 24 prevents the rotating rod 4 from passively rotating under vibration, thus preventing relative rotation between the threaded block 5 and the sliding sleeve 6, which could lead to inaccurate spacing positioning.

[0037] like Figures 1 to 4 As shown, a first knob 8 is fixedly provided on the rotating rod 4 so that by turning the first knob 8, the adjusting rotating rod 4 and the threaded sleeve 3 can rotate relative to each other, so that the distance between the first vertical plate 1 and the second vertical plate 2 changes.

[0038] like Figures 1 to 3 and Figure 5 As shown, multiple side plates 9 are fixedly provided on the side of the first vertical plate 1 and the second vertical plate 2 that are far apart from each other. The clamping and fixing mechanism includes a bidirectional screw 10, multiple limiting rods 11, two sliding plates 12 and two arc-shaped clamping plates 13. The bidirectional screw 10 is rotatably disposed on the side of the two side plates 9 that are close to each other. The multiple limiting rods 11 are fixedly disposed on the side of the two side plates 9 that are close to each other. The two sliding plates 12 are threaded onto the bidirectional screw 10. The two sliding plates 12 are slidably connected to the multiple limiting rods 11. The two arc-shaped clamping plates 13 are respectively fixedly disposed on one side of the two sliding plates 12.

[0039] A second knob 14 is fixedly provided at the top of the bidirectional screw 10, and a mounting groove 15 is provided on one side of the second vertical plate 2. A groove cover 16 is provided on the mounting groove 15. The bidirectional screw 10 can be rotated by the second knob 14.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, the ranging component includes a laser ranging sensor 17, a data processing module 18, and a power supply module. The laser ranging sensor 17 is located on one side of the second vertical plate 2. The second vertical plate 2 has a mounting groove 15. The data processing module 18 and the power supply module are both located in the mounting groove 15. The data processing module 18 is electrically connected to the laser ranging sensor 17 and the power supply module respectively to receive the data signals collected by the laser ranging sensor 17. The data processing module 18 is provided with a data storage unit for storing data and a data transmission unit for transmitting data information to the outside.

[0041] The ranging component also includes a display screen 19 and a charging interface 21. The power module is a lithium battery 20, which is electrically connected to the charging interface 21. The display screen 19 is electrically connected to the data processing module 18. The data processing module 18 can display the distance value on the display screen 19, thus eliminating the need for manual measurement. The device is powered by the lithium battery 20, and an external power adapter can be connected to the charging interface 21 to charge the lithium battery 20.

[0042] The rebar spacing monitoring retainer also includes an outer cover and a lock. The first vertical plate 1, the second vertical plate 2, the threaded sleeve 3, the rotating rod 4, the threaded block 5, and two clamping and fixing mechanisms are all located inside the outer cover. The lock is located on the outer cover and is used to lock the outer cover. By setting the outer cover and the lock, the internal components can be protected to a certain extent, avoiding damage to the entire retainer due to bumps and impacts during construction, and preventing the retainer from being manually adjusted, which would lead to monitoring failure.

[0043] In use, the device is placed between two adjacent sections of reinforcing bars. Turning the first knob 8 causes the rotating rod 4 to rotate, which in turn causes the threaded block 5 to rotate on the inner wall of the threaded sleeve 3. This moves the multiple arc-shaped clamping plates 13 away from each other, placing the two sections of reinforcing bars between them. Then, turning the two second knobs 14 causes the two bidirectional screws 10 to rotate, which in turn moves the multiple sliding plates 12 and the multiple arc-shaped clamping plates 13 closer together. The multiple closely spaced arc-shaped clamping plates 13 clamp and fix the two sections of reinforcing bars, thus maintaining the distance between adjacent sections. During the adjustment of the distance between the multiple arc-shaped clamping plates 13, the laser rangefinder 17 can adjust the distance between the first vertical plate 1 and the second vertical plate 2, indirectly measuring the maintained distance. The data processing module 18 can display the distance value on the display screen 19, thus avoiding manual measurement by personnel. Finally, when not in use, the entire device is locked with the outer casing and lock.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
