Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a rebar splice for civil engineering. Background Technology

[0002] Rebar splicers are used in civil engineering construction. A rebar splicer is a special equipment used to connect rebars in building construction. It is mainly used to solve the problem of joint connection when the rebar is not long enough or needs to be changed in direction. It connects two rebars through mechanical or chemical methods to form a continuous mechanical transmission path and avoid structural weakness caused by insufficient rebar length or change in direction.

[0003] Existing rebar splicers typically use threaded connections to connect the rebar to the sleeve. However, the threaded connection makes it prone to loosening when rotated in the opposite direction, and it requires manual splicing, which is inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar splice for civil engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a rebar splice for civil engineering, including a base, a clamping and fixing component, and a connecting sleeve; Electric push rods are installed on both sides of the upper part of the base, and a push plate is provided at one end of the electric push rod. An annular plate is provided on the push plate; the clamping and fixing assembly is provided on one side of the annular plate. A telescopic rod is installed on the upper middle part of the base, and two ear plates are installed at the top of the telescopic rod. One side of each of the two ear plates is connected to a mounting hoop, and the mounting hoop has an arc-shaped structure. The connecting sleeve is disposed between the two mounting hoops, and an adhesive storage bladder is provided in the middle of the inner wall of the connecting sleeve.

[0006] Furthermore, the clamping and fixing components include several groups and are distributed along the circumference of the annular plate; each group of clamping and fixing components includes a mounting frame connected to the annular plate, a transmission mechanism connected to the mounting frame, and a clamping plate connected to the transmission mechanism.

[0007] Furthermore, the transmission mechanism includes a lead screw, a bevel gear, a movable sleeve, and a connecting rod; the lead screw is rotatably mounted inside the mounting frame, the bevel gear is connected to the top of the lead screw, the movable sleeve is sleeved on the outside of the lead screw, the connecting rod is fixed on both sides of the movable sleeve, and the connecting rod is connected to the clamping plate.

[0008] Furthermore, the connecting rod passes through the mounting frame and is slidably connected to the mounting frame.

[0009] Furthermore, a bevel gear ring is rotatably provided on one side of the outer ring of the annular plate, and the bevel gear ring is meshed with the bevel gear.

[0010] Furthermore, the annular plate is provided with a drive assembly for driving the bevel gear ring.

[0011] Furthermore, the drive assembly includes a fixed plate, a micro motor, and a drive gear; the fixed plate is fixedly connected to the annular plate, the micro motor is mounted on one side of the fixed plate, the drive gear is connected to the output shaft side of the micro motor, and the drive gear meshes with the external teeth of the bevel gear ring.

[0012] Furthermore, three sets of clamping and fixing components are evenly arranged circumferentially on the annular plate.

[0013] Furthermore, the clamping plates have an arc-shaped structure, and a steel reinforcement body is provided between the clamping plates.

[0014] Furthermore, the push plate and the base are slidably connected.

[0015] The steel rebar splicer for civil engineering provided by this utility model has the following beneficial effects: 1. This utility model is equipped with a connecting sleeve. The upper and lower arc-shaped mounting hoops can clamp and fix the connecting sleeve. The ear plates on both sides of the mounting hoop are connected to the telescopic rod by bolts. The telescopic rod can adjust the height of the mounting hoop and the connecting sleeve to correspond with the main body of the reinforcing bar. The extension and retraction of the electric push rod facilitates the movement of the push plate, the ring plate and the clamping and fixing components, thereby driving the movement of the main body of the reinforcing bar clamped between the clamping and fixing components. This allows the main bodies of the reinforcing bars on both sides to move simultaneously to the inside of the connecting sleeve. The main bodies of the reinforcing bars on both sides can squeeze and destroy the adhesive storage bladder in the middle of the connecting sleeve, thereby releasing the adhesive and fixing and bonding the two main bodies of the reinforcing bars to the connecting sleeve.

[0016] 2. This utility model is equipped with a clamping and fixing assembly. The micro motor and output shaft facilitate the rotation of the drive gear. The drive gear meshes with the outer teeth of the bevel gear ring, which facilitates the rotation of the bevel gear ring. The bevel gear ring and the bevel gear mesh with each other, which facilitates the synchronous rotation of the three bevel gears. The rotation of the bevel gears can drive the rotation of the lead screw, which in turn drives the lead screw and the outer moving sleeve to move. This causes the moving sleeve to drive the connecting rod and the clamping plate to move, which in turn allows the three arc-shaped clamping plates to cooperate with each other to clamp and fix the main body of the steel bar, so as to facilitate the splicing of the steel bar.

[0026] like Figure 1 and Figure 3 As shown, this utility model provides a rebar splice for civil engineering, including a base 1, a clamping and fixing assembly 7, and a connecting sleeve 11. Electric push rods 2 are installed on both sides of the upper part of the base 1, and a push plate 3 is fixed to one end of each electric push rod 2. A telescopic rod 8 is installed on the upper middle part of the base 1, and two ear plates 9 are installed at the top of the telescopic rod 8. Two mounting clamps 10 are connected to one side of each ear plate 9, and the mounting clamps 10 have an arc-shaped structure. A connecting sleeve 11 is provided between the two mounting clamps 10, and two adhesive storage bladders 12 are bonded to the middle of the inner wall of the connecting sleeve 11. The two arc-shaped mounting clamps 10 can clamp the connecting sleeve 11. The mounting hoop 10 is clamped and fixed. The ear plates 9 on both sides of the mounting hoop 10 are connected to the telescopic rod 8 by bolts. The telescopic rod 8 can adjust the height of the mounting hoop 10 and the connecting sleeve 11 so that they correspond to the main body of the reinforcing bar 13. The extension and retraction of the electric push rod 2 facilitates the movement of the push plate 3, the annular plate 4 and the clamping and fixing assembly 7, thereby driving the movement of the main body of the reinforcing bar 13 clamped between the clamping and fixing assemblies 7. This allows the main bodies of the reinforcing bars 13 on both sides to move simultaneously to the inside of the connecting sleeve 11. The main bodies of the reinforcing bars 13 on both sides can squeeze and destroy the adhesive storage bladder 12 in the middle of the connecting sleeve 11, thereby releasing the adhesive and fixing the two main bodies of the reinforcing bars 13 to the connecting sleeve 11.

[0027] like Figure 1 and Figure 2 As shown, an annular plate 4 is fixed on the push plate 3, and a bevel gear ring 5 is rotatably mounted on the outer ring of one side of the annular plate 4. The push plate 3 is slidably connected to the base 1. At the same time, a drive assembly 6 is installed on the upper side of the annular plate 4. The drive assembly 6 includes a fixed plate 601, a micro motor 602, and a drive gear 603. The fixed plate 601 is fixedly connected to the annular plate 4, and a micro motor 602 is installed on one side of the fixed plate 601. The drive gear 603 is connected to the output shaft of the micro motor 602. The drive gear 603 meshes with the outer teeth of the bevel gear ring 5, and the bevel gear ring 5 meshes with the bevel gear 703. The micro motor 602 and the output shaft facilitate the rotation of the drive gear 603. The meshing connection between the drive gear 603 and the outer teeth of the bevel gear ring 5 facilitates the rotation of the bevel gear ring 5. The meshing connection between the bevel gear ring 5 and the bevel gear 703 facilitates the synchronous rotation of the three bevel gears 703, so as to facilitate the use of the clamping and fixing assembly 7.

[0028] like Figure 1 and Figure 2 As shown, three sets of clamping and fixing assemblies 7 are fixed in an array on one side of the annular plate 4. The clamping and fixing assembly 7 includes a mounting frame 701, a lead screw 702, and a bevel gear 703. The lead screw 702 is rotatably mounted inside the mounting frame 701, and the top of the lead screw 702 is connected to the bevel gear 703. The clamping and fixing assembly 7 also includes a movable sleeve 704 and a connecting rod 705. The movable sleeve 704 is sleeved on the outside of the lead screw 702, and the connecting rod 705 is fixed on both sides of the lower part of the movable sleeve 704. The clamping and fixing assembly 7 also includes a clamping plate 706, and the connecting rod 705 passes through the mounting frame 701. The frame 701 is slidably connected to the mounting frame 701, and the other end of the connecting rod 705 is fixed with a clamping plate 706. The clamping plate 706 has an arc-shaped structure, and the main body of the reinforcing bar 13 is arranged between the clamping plates 706. The rotation of the bevel gear 703 can drive the rotation of the lead screw 702, which in turn causes the lead screw 702 and the outer moving sleeve 704 to move. This causes the moving sleeve 704 to drive the connecting rod 705 and the clamping plate 706 to move, so that the three arc-shaped clamping plates 706 cooperate with each other to clamp and fix the main body of the reinforcing bar 13, so as to facilitate the splicing of the reinforcing bar.

[0029] In summary, such as Figures 1-3As shown, when using the rebar splicer for civil engineering provided by this utility model, the ear plates 9 on both sides of the mounting hoop 10 can be connected to the telescopic rod 8 by bolts, so that the upper and lower arc-shaped mounting hoop 10 clamps and fixes the connecting sleeve 11. Then, the rebar body 13 is passed through the middle of the annular plate 4 and placed between the clamping and fixing components 7. Then, the micro motor 602 and the output shaft drive the rotation of the drive gear 603. The drive gear 603 is meshed with the outer teeth of the bevel gear ring 5, which can drive the rotation of the bevel gear ring 5. The bevel gear ring 5 is meshed with the bevel gear 703, which can drive the synchronous rotation of the three bevel gears 703. The rotation of the bevel gear 703 can drive the rotation of the lead screw 702, which in turn drives the movement of the lead screw 702 and the outer moving sleeve 704. The moving sleeve 704 drives the movement of the connecting rod 705 and the clamping plate 706, which in turn allows the three arc-shaped clamping plates 706 to cooperate with each other to clamp and fix the rebar body 13.

[0030] Then, the height of the mounting hoop 10 and the connecting sleeve 11 is adjusted by the telescopic rod 8 to correspond with the main body of the reinforcing bar 13. Then, the extension and retraction of the electric push rod 2 drives the push plate 3, the annular plate 4 and the clamping and fixing assembly 7 to move, thereby driving the main body of the reinforcing bar 13 clamped between the clamping and fixing assemblies 7 to move. This allows the main bodies of the reinforcing bars 13 on both sides to move to the inside of the connecting sleeve 11 at the same time. The main bodies of the reinforcing bars 13 on both sides can squeeze and destroy the adhesive storage bladder 12 in the middle of the connecting sleeve 11, thereby releasing the adhesive. This makes the two main bodies of the reinforcing bars 13 fixed and bonded to the connecting sleeve 11, thus completing the reinforcing bar splicing process.

[0031] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
