Description

Technical Field

[0001] This invention relates to the field of concrete beam junction connection technology, specifically a connection device for the junction of a steel-concrete composite column and a cast-in-place concrete beam. Background Technology

[0002] The junction of steel-concrete composite columns and cast-in-place concrete beams is a common connection type in structural engineering. It is used to connect columns and beams so that they can transfer loads and withstand deformation.

[0003] Welding between steel-concrete composite columns and cast-in-place concrete beams is a common structural connection method that ensures strong joints and structural stability. Welding between steel-concrete composite columns and cast-in-place concrete beams has several advantages in handling junction joints, making it a common and effective structural connection method.

[0004] During the welding process, the reinforcing bars and steel brackets need to be welded together to ensure the structural strength of the concrete beam composed of reinforcing bars and concrete. Current technology usually uses manual welding. Since the welding points are usually located at high positions, it is inconvenient to move up and down, and there is also the problem of insufficient working space. In addition, it is usually inconvenient to fix the reinforcing bars during welding, which can cause the reinforcing bars to move during welding, resulting in poor welding quality. Summary of the Invention

[0005] In view of the technical problems existing in the application of the connection device for the junction of steel-concrete composite column and cast-in-place concrete beam, the present invention provides a connection device for the junction of steel-concrete composite column and cast-in-place concrete beam.

[0006] A connection device for the junction of a steel-concrete composite column and a cast-in-place concrete beam includes a connecting seat, a positioning mechanism on the connecting seat, and an installation component on the left side of the connecting seat.

[0007] The installation assembly is equipped with a pressing mechanism and a welding assembly. The pressing mechanism is used to fix the reinforcing bars during welding, and the welding assembly is used to weld the reinforcing bars.

[0008] The positioning mechanism includes an electric push rod, which is mounted on the top of the connecting seat. A connecting frame is fixedly connected to the telescopic end of the electric push rod. A first arc-shaped plate is fixedly connected to the end of the connecting frame away from the electric push rod. A mounting column is fixedly connected to the bottom of the connecting seat. The first arc-shaped plate is slidably connected inside the mounting column. A second arc-shaped plate is slidably connected inside the mounting column. A limit rail is connected to the inner wall of the mounting column. The limit rail and the second arc-shaped plate are slidably connected. A spring is provided inside the mounting column. The spring and the second arc-shaped plate are fixedly connected.

[0009] Furthermore, the mounting assembly includes an upper mounting base, which is fixedly connected to a connecting base, and a lower mounting base is fixedly connected below the upper mounting base, with a sliding groove formed on the surface of the lower mounting base.

[0010] Furthermore, the pressing mechanism is disposed between the upper mounting base and the lower mounting base. The pressing mechanism includes a positioning frame, which is disposed between the upper mounting base and the lower mounting base. A second motor is mounted on the positioning frame, and a second gear is fixedly connected to the output end of the second motor. A fixed frame is slidably connected inside the positioning frame. A toothed plate is provided on the inner wall of the fixed frame, and the toothed plate meshes with the second gear. A pressing frame is fixedly connected to one end of the fixed frame extending outside the positioning frame. A lifting assembly is provided on the upper positioning frame, and the lifting assembly controls the lifting and lowering of the pressing mechanism.

[0011] Furthermore, a limiting frame is fixedly connected above the positioning frame, and a limiting rod is fixedly connected to the pressing frame. The limiting rod and the limiting frame are slidably connected.

[0012] Furthermore, the lifting assembly includes a fixed cylinder, two fixed cylinders are symmetrically slidably connected to the upper positioning seat, and the two fixed cylinders are fixedly connected to a fixed plate. A hydraulic cylinder is installed on the fixed plate, a fixed rod is fixedly connected to the limiting frame, the fixed rod and the fixed cylinder are slidably connected, and a connecting plate is fixedly connected to the telescopic end of the hydraulic cylinder. The connecting plate and the fixed plate are fixedly connected.

[0013] Furthermore, a drive assembly is provided on the upper mounting base. The drive assembly includes a first motor, and a first gear is fixedly connected to the output end of the first motor. A connecting frame is fixedly connected to the fixing plate, and a toothed plate is provided on the connecting frame. The toothed plate meshes with the first gear.

[0014] Furthermore, the welding assembly includes a movable base located on the front side of the pressing plate, a third motor mounted on the top of the movable base, a first lead screw fixedly connected to the output end of the third motor, the first lead screw being rotatably connected inside the movable base, and a movable component being provided on the movable base.

[0015] Furthermore, the moving component includes a moving plate, which is slidably connected within the moving base and threadedly connected to a first lead screw. A fourth motor is installed at the end of the moving plate away from the moving base. A second lead screw is fixedly connected to the output end of the fourth motor. The second lead screw is rotatably connected within the moving plate. A nut seat is threadedly connected to the second lead screw. The nut seat is slidably connected within the moving plate. A welding torch is installed on the threaded seat.

[0016] The beneficial effects of this invention are:

[0017] 1. The combination of the pressing mechanism and the welding components solves the problems of high working points and inconvenience in manual welding, as well as the problem of small working space and inconvenience in manual welding. At the same time, the pressing mechanism can also fix the steel bars during welding to prevent shaking and ensure smooth welding process.

[0018] 2. The coordinated design of the pressing mechanism and welding components ensures that the reinforcing bars will not move during welding, thus ensuring a smooth welding process. The pressing frame can simultaneously fix multiple reinforcing bars in two groups, eliminating the need to move the pressing mechanism to re-fix them after welding one bar, thereby improving work efficiency. The lifting component controls the vertical movement of the pressing frame, while the pressing mechanism, in conjunction with its second motor, second gear, and fixed frame, moves horizontally to fix the upper and lower groups of reinforcing bars.

[0019] 3. The positioning mechanism is used to install the entire connecting device on two vertically intersecting steel plates. The specific installation steps are as follows: first, place the entire device on top of the vertically arranged steel plates, then slowly lower it until the mounting column and the reinforcing rib contact each other. Then, with the cooperation of the electric push rod, connecting frame, mounting column, first arc plate, second arc plate and spring, the second arc plate finally contacts the inner wall of the vertically arranged steel plate, thereby completing the installation of the entire connecting device. The spring has the function of rebound and buffering. The above-mentioned components facilitate the installation and disassembly of the connecting device.

[0020] 4. The drive assembly is used to move the pressing mechanism and the welding assembly. After welding is completed at one end of the rebar, the drive assembly moves the pressing mechanism and the welding assembly to the other end of the rebar for welding. During this process, the mounting assembly is used to limit the pressing mechanism and the welding assembly, thereby moving the welding assembly and the pressing mechanism to the designated position. Specifically, the first motor is started, which drives the first gear fixedly connected to it to rotate. The first gear drives the toothed plate meshing with it to move, which in turn drives the connecting frame of the mounting toothed plate to move, thereby driving the fixed cylinder fixedly connected to the connecting frame to move synchronously, and finally driving the welding assembly and the pressing mechanism to move. The upper mounting seat is provided with a dovetail groove, and the fixed cylinder is slidably connected to the dovetail groove. The sliding groove opened on the lower positioning seat is slidably connected to the moving seat, thereby limiting the moving seat. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a connection device for the junction of a steel-concrete composite column and a cast-in-place concrete beam includes a connecting seat 1, a positioning mechanism 2 on the connecting seat 1, and an installation component 3 on the left side of the connecting seat 1.

[0032] The installation assembly 3 is provided with a pressing mechanism 5 and a welding assembly 6. The pressing mechanism 5 is used to fix the reinforcing bar during welding, and the welding assembly 6 is used to weld the reinforcing bar.

[0033] The positioning mechanism 2 includes an electric push rod 201, which is mounted on the top of the connecting seat 1. A connecting frame 202 is fixedly connected to the telescopic end of the electric push rod 201. A first arc-shaped plate 204 is fixedly connected to the end of the connecting frame 202 away from the electric push rod 201. A mounting column 203 is fixedly connected to the bottom of the connecting seat 1. The first arc-shaped plate 204 is slidably connected inside the mounting column 203. A second arc-shaped plate 205 is slidably connected inside the mounting column 203. A limit rail is connected to the inner wall of the mounting column 203. The limit rail and the second arc-shaped plate 205 are slidably connected. A spring 206 is provided inside the mounting column 203. The spring 206 and the second arc-shaped plate 205 are fixedly connected. The limit rail allows the second arc-shaped plate 205 to move only left and right.

[0034] like Figure 1 As shown, the concrete column is made up of two vertically set steel plates that are cross-fixed together. The two vertically set steel plates are fixedly connected with reinforcing bars, and the ends of the steel plates are provided with side plates. Steel brackets are provided on the side plates. Multiple steel bars run through the vertically set steel plates and overlap the surface of the steel brackets.

[0035] The positioning mechanism 2 is used to install the entire connecting device on two vertically intersecting steel plates. The specific installation steps are as follows: First, place the entire device on top of the vertically arranged steel plates, then slowly lower it until the mounting column 203 and the reinforcing rib contact. Then, start the electric push rod 201, which further pushes the connecting frame 202 to move. The connecting frame 202 drives the first arc-shaped plate 204, which is fixedly connected to it, to move within the mounting column 203. As the first arc-shaped plate 204 presses against the second arc-shaped plate 205, the spring 206 is compressed, and the second arc-shaped plate 205 gradually moves out of the mounting column 203. Finally, the second arc-shaped plate 205 contacts the inner wall of the vertically arranged steel plate. The spring 206 has the function of rebound and buffering. When it is necessary to disassemble the entire connecting device, the first arc-shaped plate 204 is controlled not to press against the second arc-shaped plate 205 through the above process. Under the action of the spring force of the spring 206, the second arc-shaped plate 205 does not contact the steel plate, thereby disassembling the entire connecting device.

[0036] like Figure 5 As shown, the mounting component 3 includes an upper mounting base 301, which is fixedly connected to the connecting base 1. A lower mounting base 302 is fixedly connected below the upper mounting base 301. A sliding groove 303 is provided on the surface of the lower mounting base 302. The mounting component 3 is used to connect the pressing mechanism 5 and the welding component 6.

[0037] like Figure 6 As shown, the pressing mechanism 5 is disposed between the upper mounting base 301 and the lower mounting base 302. The pressing mechanism 5 includes a positioning frame 501, which is disposed between the upper mounting base 301 and the lower mounting base 302. A second motor 502 is mounted on the positioning frame 501. A second gear 504 is fixedly connected to the output end of the second motor 502. A fixed frame 503 is slidably connected inside the positioning frame 501. A toothed plate is provided on the inner wall of the fixed frame 503. The toothed plate meshes with the second gear 504. A pressing frame 505 is fixedly connected to one end of the fixed frame 503 that extends outside the positioning frame 501. A lifting assembly 7 is provided on the positioning frame 501. The lifting assembly 7 controls the lifting and lowering of the pressing mechanism 5.

[0038] The pressing mechanism 5 fixes both ends of the reinforcing bar during welding, preventing movement and ensuring proper welding. The pressing frame 505 can simultaneously fix multiple reinforcing bars from two groups, eliminating the need to move the pressing mechanism 5 after welding each bar, thus improving work efficiency. The pressing mechanism 5 fixes the reinforcing bar as follows: First, the second motor 502 is started, driving the second gear 504 to rotate. The second gear 504 moves the meshing gear plate, which in turn moves the fixing frame 503. The fixing frame 503 then moves the pressing frame 505, which is fixedly connected to it, to the top of the reinforcing bar. The lifting assembly 7 then brings the pressing frame 505 into contact with and presses the reinforcing bar, ultimately fixing it.

[0039] like Figure 5 , Figure 6 As shown, a limiting frame 506 is fixedly connected above the positioning frame 501, and a limiting rod 507 is fixedly connected to the pressing frame 505. The limiting rod 507 and the limiting frame 506 are slidably connected. The cooperation between the limiting frame 506 and the limiting rod 507 can ensure the stability of the pressing frame 505 when it moves.

[0040] like Figure 6 As shown, the lifting assembly 7 includes a fixed cylinder 701. Two fixed cylinders 701 are symmetrically slidably connected to the upper mounting base 301, and a fixed plate is fixedly connected to the two fixed cylinders 701. A hydraulic cylinder 703 is mounted on the fixed plate. A fixed rod 702 is fixedly connected to the limiting frame 506. The fixed rod 702 and the fixed cylinder 701 are slidably connected. A connecting plate 704 is fixedly connected to the telescopic end of the hydraulic cylinder 703. The connecting plate 704 and the fixed rod 702 are fixedly connected.

[0041] The lifting assembly 7 controls the lifting of the pressing frame 505 as follows: first, the hydraulic cylinder 703 is started to drive the connecting plate 704 to move. The connecting plate 704 drives the fixed rod 702, which is fixedly connected to it, to move. The limit frame 506, which is fixedly connected to the fixed rod 702, moves synchronously, and finally drives the pressing frame 505, which is connected to the limit frame 506, to move.

[0042] like Figure 7 , Figure 8 As shown, a drive assembly 4 is provided on the upper mounting base 301. The drive assembly 4 includes a first motor 401. A first gear 402 is fixedly connected to the output end of the first motor 401. A connecting frame 403 is fixedly connected to the fixing plate. A toothed plate is provided on the connecting frame 403. The toothed plate meshes with the first gear 402.

[0043] The drive assembly 4 is used to move the pressing mechanism 5 and the welding assembly 6. After welding is completed at one end of the steel bar, the drive assembly 4 moves the pressing mechanism 5 and the welding assembly 6 to the other end of the steel bar for welding. During this process, the mounting assembly 3 is used to limit the pressing mechanism 5 and the welding assembly 6, so that the welding assembly 6 and the pressing mechanism 5 move to the designated position. Specifically, the first motor 401 is started first, and the first motor 401 drives the first gear 402 fixedly connected to it to rotate. The first gear 402 drives the toothed plate that meshes with it to move, and further drives the connecting frame 403 of the mounting toothed plate to move, thereby driving the fixed cylinder 701 fixedly connected to the connecting frame 403 to move synchronously, and finally driving the welding assembly 6 and the pressing mechanism 5 to move. The upper mounting base 301 is provided with a dovetail groove, and the fixed cylinder 701 is slidably connected to the dovetail groove. The sliding groove 303 opened on the lower mounting base 302 is slidably connected to the moving base 602, thereby limiting the moving base 602.

[0044] like Figure 5 , Figure 6 As shown, the welding assembly 6 includes a movable base 602, which is located on the front side of the pressing frame 505. A synchronizing rod is fixedly connected to the pressing frame 505, and the synchronizing rod and the movable base 602 are slidably connected. The third motor 601 is installed on the top of the movable base 602, and the output end of the third motor 601 is fixedly connected to a first lead screw 603. The first lead screw 603 is rotatably connected inside the movable base 602, and a moving assembly 8 is provided on the movable base 602.

[0045] like Figure 7 , Figure 8As shown, the moving component 8 includes a moving plate 802, which is slidably connected to the moving base 602 and threadedly connected to the first lead screw 603. A fourth motor 801 is installed at the end of the moving plate 802 away from the moving base 602. A second lead screw 803 is fixedly connected to the output end of the fourth motor 801. The second lead screw 803 is rotatably connected to the moving plate 802. A nut seat is threadedly connected to the second lead screw 803. The nut seat is slidably connected to the moving plate 802. A welding torch 9 is installed on the threaded seat.

[0046] The welding assembly 6 and the moving assembly 8 are used to drive the welding torch 9 to weld multiple steel bars in two groups. When welding the same group of steel bars, the fourth motor 801 is started to drive the second lead screw 803 to move, thereby driving the nut seat threaded to it to move, and then driving the welding torch 9 on the nut seat to move, so that the same group of multiple steel bars can be welded in sequence. The pressing mechanism 5 is used to fix the steel bars, so that the steel bars will not move during welding, ensuring that the welding process can proceed smoothly. After welding a group of steel bars, the pressing mechanism 5 drives the moving seat 602 to move away from the steel bars. The synchronous rod drives the moving seat 602 to move synchronously, thereby avoiding interference between the moving plate 802 in the moving assembly 8 and the steel bars when moving to the next group of steel bars. The third motor 601 is started to drive the first lead screw 603 to rotate. The first lead screw 603 drives the moving plate 802 threaded to it to move, and then drives the welding torch 9 set on the moving plate 802 to move synchronously until the welding torch 9 moves above the next group of steel bars, and then the steel bars are welded.
