Description

Technical Field

[0001] This invention relates to a welding and splicing device for irregularly shaped steel, specifically a guide welding and splicing device for large-section irregularly shaped steel, belonging to the field of splicing device technology. Background Technology

[0002] A rebar splice is a mechanical connection device used to connect two rebars. It typically employs a threaded sleeve structure and is widely used in construction engineering. It is primarily used for joining two rebars in reinforced concrete structures. Its core function is to replace traditional welding or tying with a mechanical connection, ensuring the strength, stability, and construction efficiency of the rebar connection. It is cylindrical in shape, and the central part can be solid or open.

[0003] Patent CN114250915B discloses a self-protecting pre-embedded rebar connector and its construction method. The connector includes: a connecting sleeve for connecting the ends of the rebar; a protective sleeve having two opposing open ends; and a support assembly for supporting the inner side of the formwork and with an adjustable length, detachably inserted into the other open end. This invention solves the problems of poor stability, difficult positioning, and easy contamination of the connecting ends in existing pre-embedded connector protection devices.

[0004] During the construction of large buildings, steel-reinforced concrete columns are used to support and fix the building. Although the connector in the aforementioned patent improves the stability of the steel bar connection, when constructing with non-cubic (such as trapezoidal) concrete columns, it is necessary to weld the connector at the same tilt angle according to the design tilt angle. This is cumbersome for construction workers, increasing welding difficulty and reducing construction efficiency. To address these issues, we provide a guide-type welding connector device for large-section irregular steel profiles. Summary of the Invention

[0005] The purpose of this invention is to provide a guide welding joint device for large-section irregular steel to solve the above-mentioned problems, thereby solving the problem of cumbersome welding of joints in the inclined direction in the prior art.

[0006] The present invention is achieved through the following technical solution: a guide welding connection device for large cross-section irregular steel.

[0007] The device includes an I-beam column, with an inclined fixing plate on its exterior. Adjustment mechanisms for adjusting the angle of the inclined fixing plate are arranged equidistantly on the surface of the I-beam column. Each adjustment mechanism includes a first fixing claw, a second fixing claw, an inclined plate, a connecting plate, and a fixing tube. A fixing frame for supporting the inclined fixing plate is fixedly connected to the surface of the inclined plate. A positioning mechanism is provided between the two sets of adjustment mechanisms. The positioning mechanism includes a supporting sleeve, an adjusting vertical rod, and a fixing nut, and the adjusting vertical rod is inserted into the adjacent fixing tube.

[0008] Preferably, the surface of the inclined fixing plate is fixedly connected with equidistantly arranged steel bar fixing sleeves, the first fixing claw and the second fixing claw are both snapped into the surface of the I-beam column, the surface of the second fixing claw is fixedly connected with a fixing vertical plate, and the inclined plate is rotatably connected to the fixing vertical plate. By fixing the vertical plate, one end of the inclined plate is fixed, thereby improving the stability of the inclined plate angle adjustment.

[0009] Preferably, the inclined fixing plate has two fixing buckles fixedly connected to its surface, and each fixing buckle is inserted into the adjacent fixing frame. The fixing tubes are equidistantly arranged and fixed on the upper and lower sides of the inclined plate. The middle of the fixing vertical plate is rotatably connected to a power screw, and one end of the power screw is fixedly connected to a first connector. The inclined fixing plate is fixed to the two inclined plate surfaces by inserting the fixing buckles into the fixing frame, thereby improving the convenience of fixing and installing the inclined fixing plate.

[0010] Preferably, a limiting rod is fixedly connected to the surface of the connecting plate, and a sliding plate is threadedly connected to the other end of the power screw. The sliding plate is slidably connected to the limiting rod. An angle adjusting plate is rotatably connected to the surface of the sliding plate, and the other end of the angle adjusting plate is rotatably connected to the inclined plate. A support plate is fixedly connected to the surface of the first fixed claw. The limiting rod limits the sliding plate, making the sliding plate more stable in the lateral sliding of the connecting plate. The rotation of the power screw drives the sliding plate to slide laterally in the connecting plate. Through the transmission of the angle adjusting plate, the other end of the inclined plate is driven to flip outward, adjusting the inclined plate to a specified horizontal angle so that the inclined plate is perpendicular to the inclined direction.

[0011] Preferably, a second connector is rotatably connected to the middle of the support plate, and adjusting screws are rotatably connected to both ends of the support plate. One end of each adjusting screw is threadedly connected to the connecting plate, and the other end of the adjusting screw is fixedly connected to a linkage sprocket. The linkage sprocket is connected to the second connector via a chain drive. An electric wrench is fitted onto the surface of the second connector, causing the second connector to rotate via the chain, which in turn causes the linkage sprocket to drive the adjusting screw to rotate. The adjusting screw rotates inside the connecting plate, causing the first and second fixing claws to approach each other and clamp onto the surface of the I-beam column.

[0012] Preferably, a sliding block is fixedly connected to the surface of the first fixed claw, a limiting groove is formed in the middle of the connecting plate, and the limiting groove is slidably connected to the sliding block. A telescopic plate is slidably connected inside the inclined plate, and a pulling rod is fixedly connected to one end of the telescopic plate. Two fixed tubes are fixed to both ends of the pulling rod. The limiting groove and the sliding block limit the position of the connecting plate and the first fixed claw, thereby improving the stability of the connecting plate sliding on the surface of the first fixed claw.

[0013] Preferably, the telescopic plate has connecting slots on both sides, and connecting blocks are inserted into the connecting slots. The surface of the connecting blocks is on the same horizontal plane as the pull rod, and a fixing tube is fixedly connected to the surface of the connecting blocks. The connecting blocks are inserted into the connecting slots, and after assembly, the connection can be fixed and positioned by welding, fixing the required fixing tubes to the upper and lower sides of the telescopic plate, thereby improving the stability of the fixing tube installation.

[0014] Preferably, the support sleeve has a sliding groove inside, and the other end of the adjusting rod is fixedly connected to a limiting block, with the protrusion of the limiting block slidably connected to the sliding groove. A rotating slip ring is rotatably connected to the surface of the support sleeve, and the limiting block is positioned by the sliding groove, thereby improving the stability of the limiting block sliding up and down inside the support sleeve.

[0015] Preferably, the surface of the adjusting vertical rod is threaded with an adjusting screw ring, and the adjusting screw ring is rotatably connected to the supporting sleeve. The surface of the inclined fixing plate is provided with a connecting groove, and the position of each connecting groove corresponds to the position of the rotating slip ring. By adjusting the screw ring, the position of the adjusting vertical rod is vertically adjusted so that the adjusting vertical rod is inserted into the corresponding fixing tube, thereby supporting and fixing the two sets of adjusting mechanisms.

[0016] Preferably, the fixing nut is movably connected to the connecting groove, and the screw end of the fixing nut is threadedly connected to the rotating slip ring. A support washer is fitted in the middle of the fixing nut, and the support washer abuts against the inclined fixing plate. By inserting the fixing nut into the connecting groove, the fixing nut and the rotating slip ring are fixedly assembled together, thereby fixing the inclined fixing plate and the support sleeve together. The support washer increases the contact area between the fixing nut and the surface of the inclined fixing plate, thereby increasing the fixing force of the fixing nut on the inclined fixing plate.

[0017] This invention provides a guide-type welding connection device for large-section irregular-shaped steel, which has the following beneficial effects: 1. This guide-type welding splicing device for large-section irregular steel profiles adjusts the angle of the inclined fixing plate, thereby adjusting the angle of the rebar fixing sleeve. This ensures that the rebar fixing sleeve and the inclined direction are aligned in a straight line, reducing the welding difficulty of the splice and improving the welding efficiency of the irregular steel profile. The first and second fixing claws are engaged with the surface of the I-beam column to support and position the adjustment mechanism, improving the installation efficiency of the adjustment mechanism. Adjusting the angle of the inclined plate reduces the difficulty of adjusting the angle of the inclined fixing plate. The fixing frame secures the inclined fixing plates together, improving the stability and convenience of the assembly connection. The support sleeve and adjusting vertical rod support and connect the two sets of adjustment mechanisms, connecting multiple sets of adjustment mechanisms together and improving the stability of the device operation. The fixing nut secures the inclined fixing plate to the surface of the support sleeve, increasing the fixing force on the inclined fixing plate and improving the stability of the device in use.

[0018] 2. The guide welding connection device for this large-section irregular steel section uses a fixed vertical plate to fix one end of the inclined plate, improving the stability of the inclined plate angle adjustment. A fixing buckle inserted into the fixing frame fixes the inclined fixing plate to the surfaces of the two inclined plates, improving the convenience of installation. An electric wrench is placed on the surface of the first connector, causing the first connector to drive the power screw to rotate. A limit rod limits the sliding plate, making the sliding plate more stable in the lateral sliding of the connecting plate. The rotation of the power screw causes the sliding plate to slide laterally in the connecting plate. Through the transmission of the angle adjustment plate, the other end of the inclined plate is rotated outward, adjusting the inclined plate to the specified horizontal angle, making the inclined plate perpendicular to the inclined direction. An electric wrench is placed on the surface of the second connector, causing the second connector to rotate via a chain-controlled linkage sprocket. This linkage sprocket then drives the adjustment screw to rotate. The adjustment screw rotates inside the connecting plate, shortening the distance between the connecting plate and the support plate, thus bringing the first and second fixing claws closer together and clamping them onto the surface of the I-beam column.

[0019] 3. This guide-type welding joint device for large-section irregular steel profiles uses limiting grooves and sliding blocks to limit the position of the connecting plate and the first fixing claw, improving the stability of the connecting plate sliding on the surface of the first fixing claw. The telescopic plate slides inside the inclined plate, increasing the length of the inclined plate, allowing the device to be used with steel-concrete columns of different widths, thus improving the device's effectiveness. A pull rod positions the fixing pipe, improving the stability of the fixing installation. A connecting clip is inserted into the connecting slot, and welding can be used to fix the connection point after assembly, securing the required fixing pipe to the telescopic plate. The upper and lower sides improve the stability of the fixed pipe installation. The sliding groove positions the limit block, improving the stability of the limit block sliding up and down inside the support sleeve. The adjusting screw ring is used to vertically adjust the position of the adjusting rod, so that the adjusting rod is inserted into the corresponding fixed pipe, thereby supporting and fixing the two sets of adjusting mechanisms. The fixing nut is inserted into the connecting groove, so that the fixing nut and the rotating slip ring are fixed together, thereby fixing the inclined fixing plate to the support sleeve. The support shim increases the contact area between the fixing nut and the surface of the inclined fixing plate, increasing the fixing force of the fixing nut on the inclined fixing plate.

[0022] This invention provides a guide-type welding connection device for large-section irregular steel.

[0023] Please see Figure 1 and Figure 4 The system includes an I-beam column 1, an inclined fixing plate 2 on the outside of the I-beam column 1, and equidistantly arranged steel bar fixing sleeves 3 fixedly connected to the surface of the inclined fixing plate 2. By adjusting the angle of the inclined fixing plate 2, the angle value of the steel bar fixing sleeves 3 can be adjusted so that the steel bar fixing sleeves 3 are in the same straight line direction as the inclined direction, reducing the welding difficulty of the connector, improving the welding efficiency of irregular steel sections, and fixing the steel bars through the steel bar fixing sleeves 3, thereby improving the stability of the steel bar fixed connection.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The surface of the I-beam column 1 is equidistantly arranged with adjustment mechanisms 4 for adjusting the angle of the inclined fixing plate 2. The adjustment mechanism 4 includes a first fixing claw 401, a second fixing claw 402, an inclined plate 404, a connecting plate 408, and a fixing tube 418. The surface of the inclined plate 404 is fixedly connected with a fixing frame 419 that supports the inclined fixing plate 2. The first fixing claw 401 and the second fixing claw 402 are engaged with the surface of the I-beam column 1 to support and position the adjustment mechanism 4, thereby improving the installation efficiency of the adjustment mechanism 4. By adjusting the angle of the inclined plate 404, the difficulty of adjusting the angle of the inclined fixing plate 2 is reduced. The fixing frame 419 is used to fix the inclined fixing plate 2 and the inclined plate 404 together, thereby improving the stability and convenience of the assembly connection of the inclined fixing plate 2.

[0025] The first fixing claw 401 and the second fixing claw 402 are both engaged with the surface of the I-beam column 1. The surface of the second fixing claw 402 is fixedly connected to a fixing vertical plate 403, and the tilting plate 404 is rotatably connected to the fixing vertical plate 403. The fixing vertical plate 403 fixes one end of the tilting plate 404, thereby improving the stability of the tilting plate 404 angle adjustment.

[0026] Two fixing buckles 420 are fixedly connected to the surface of the inclined fixing plate 2, and each fixing buckle 420 is inserted into the adjacent fixing frame 419. The fixing tubes 418 are equidistantly arranged and fixed on the upper and lower sides of the inclined plate 404. The middle of the fixed vertical plate 403 is rotatably connected to the power screw 410. One end of the power screw 410 is fixedly connected to the first connector 411. The inclined fixing plate 2 is fixed to the surface of the two inclined plates 404 by inserting the fixing buckles 420 into the fixing frame 419, which improves the convenience of fixing and installing the inclined fixing plate 2. An electric wrench is placed on the surface of the first connector 411, so that the first connector 411 drives the power screw 410 to rotate.

[0027] A limiting rod 409 is fixedly connected to the surface of the connecting plate 408. The other end of the power screw 410 is threadedly connected to a sliding plate 423, and the sliding plate 423 is slidably connected to the limiting rod 409. An angle adjusting plate 407 is rotatably connected to the surface of the sliding plate 423, and the other end of the angle adjusting plate 407 is rotatably connected to the inclined plate 404. A support plate 412 is fixedly connected to the surface of the first fixed claw 401. The limiting rod 409 limits the sliding plate 423, making the sliding plate 423 slide more stably in the lateral direction of the connecting plate 408. The rotation of the power screw 410 drives the sliding plate 423 to slide laterally in the connecting plate 408. Through the transmission of the angle adjusting plate 407, the other end of the inclined plate 404 is rotated outward, adjusting the inclined plate 404 to a specified horizontal angle, so that the inclined plate 404 is perpendicular to the inclined direction.

[0028] A second connector 414 is rotatably connected to the middle of the support plate 412, and adjusting screws 413 are rotatably connected to both ends of the support plate 412. One end of each adjusting screw 413 is threadedly connected to the connecting plate 408, and the other end of the adjusting screw 413 is fixedly connected to a linkage sprocket 415. The linkage sprocket 415 is connected to the second connector 414 via chain drive. An electric wrench is placed on the surface of the second connector 414, causing the second connector 414 to rotate via the chain control of the linkage sprocket 415. This causes the linkage sprocket 415 to drive the adjusting screws 413 to rotate. As the adjusting screws 413 rotate inside the connecting plate 408, the distance between the connecting plate 408 and the support plate 412 is shortened, thereby bringing the first fixing claw 401 and the second fixing claw 402 closer together and clamping them on the surface of the I-beam column 1.

[0029] A sliding block 416 is fixedly connected to the surface of the first fixed claw 401. A limiting groove 417 is formed in the middle of the connecting plate 408, and the limiting groove 417 is slidably connected to the sliding block 416. A telescopic plate 405 is slidably connected inside the inclined plate 404. A pulling rod 406 is fixedly connected to one end of the telescopic plate 405, and two fixed tubes 418 are fixed to both ends of the pulling rod 406. The limiting groove 417 and the sliding block 416 limit the position of the connecting plate 408 and the first fixed claw 401, raising the connecting plate 408 in the first fixed claw 401. The stability of the sliding surface of the fixed claw 401 is improved by the sliding of the telescopic plate 405 inside the inclined plate 404, which increases the length of the inclined plate 404, making the device applicable to steel-concrete columns of different widths and improving the effectiveness of the device. After the telescopic plate 405 is adjusted, the gap between the telescopic plate 405 and the inclined plate 404 is welded to position and fix the telescopic plate 405, improving the ease of installation of the telescopic plate 405. The fixed tube 418 is positioned by pulling the rod 406, improving the stability of the fixed tube 418 installation.

[0030] The telescopic plate 405 has connecting slots 421 on both sides. Connecting blocks 422 are inserted into the connecting slots 421. The surface of the connecting blocks 422 is on the same horizontal plane as the pull rod 406. A fixing tube 418 is fixedly connected to the surface of the connecting blocks 422. The connecting blocks 422 are inserted into the connecting slots 421. After assembly, the connection can be fixed and positioned by welding. The required fixing tube 418 is fixed on the upper and lower sides of the telescopic plate 405, which improves the stability of the fixing tube 418.

[0031] Please refer to it again. Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 12A positioning mechanism 5 is provided between the two sets of adjustment mechanisms 4. The positioning mechanism 5 includes a support sleeve 501, an adjusting vertical rod 502, and a fixing nut 507. The adjusting vertical rod 502 is inserted into the adjacent fixing pipe 418. The support sleeve 501 and the adjusting vertical rod 502 support and connect the two sets of adjustment mechanisms 4, connecting multiple sets of adjustment mechanisms 4 together and improving the stability of the device operation. The fixing nut 507 fixes the inclined fixing plate 2 to the surface of the support sleeve 501, increasing the fixing force on the inclined fixing plate 2 and improving the stability of the device.

[0032] The support sleeve 501 has a sliding groove 505 inside. The other end of the adjusting vertical rod 502 is fixedly connected to a limiting block 504, and the protrusion of the limiting block 504 is slidably connected to the sliding groove 505. The surface of the adjusting vertical rod 502 is threadedly connected to an adjusting screw ring 503, and the adjusting screw ring 503 is rotatably connected to the support sleeve 501. The limiting block 504 is positioned by the sliding groove 505, which improves the stability of the limiting block 504 sliding up and down inside the support sleeve 501. The position of the adjusting vertical rod 502 is vertically adjusted by the adjusting screw ring 503, so that the adjusting vertical rod 502 is inserted into the corresponding fixed tube 418, thereby supporting and fixing the two sets of adjusting mechanisms 4.

[0033] The inclined fixing plate 2 has connecting grooves 509 on its surface, and each connecting groove 509 corresponds to the position of the rotating slip ring 506. The connecting grooves 509 are through grooves on the surface of the inclined fixing plate 2 according to the position of the rotating slip ring 506. The rotating slip ring 506 is rotatably connected to the surface of the support sleeve 501. The fixing nut 507 is movably connected to the connecting groove 509, and the screw end of the fixing nut 507 is threaded to the rotating slip ring 506. A support washer 508 is fitted in the middle of the fixing nut 507, and the support washer 508 abuts against the inclined fixing plate 2. By inserting the fixing nut 507 into the connecting groove 509, the fixing nut 507 and the rotating slip ring 506 are fixedly assembled together, thereby fixing the inclined fixing plate 2 and the support sleeve 501 together. The support washer 508 increases the contact area between the fixing nut 507 and the surface of the inclined fixing plate 2, thereby increasing the fixing force of the fixing nut 507 on the inclined fixing plate 2.

[0034] A connector is a rebar connection material, essentially a steel sleeve with internal threads. These threads can be either tapered or straight. The rebar fixing sleeve 3 of this application is a type of connector. During steel-concrete composite construction, the inclined fixing plate 2 is fixed at a certain angle to the surface of the I-beam column 1. The main reinforcing bars are then fixed and installed using the rebar fixing sleeve 3, improving the efficiency of steel-concrete composite construction.

[0035] Working principle: During the construction of the trapezoidal steel-concrete structure, the inclination angle is first determined according to the inclination direction. Then, the first fixing claw 401 and the second fixing claw 402 are placed on both sides of the I-beam column 1, and the limiting groove 417 is placed on the surface of the sliding block 416. An electric wrench is placed on the surface of the second connector 414, causing the second connector 414 to rotate via a chain-controlled linkage sprocket 415. This, in turn, causes the linkage sprocket 415 to drive the adjusting screw 413 to rotate. The adjusting screw 413 rotates inside the connecting plate 408, shortening the distance between the connecting plate 408 and the support plate 412, thereby bringing the first fixing claw 401 and the second fixing claw 402 closer together. The first fixing claw 401 and the second fixing claw 402 are clamped onto the surface of the I-beam column 1. After the first fixing claw 401 and the second fixing claw 402 are fixed, the connection can be reinforced by welding. In this way, several sets of adjustment mechanisms 4 are fixed to the surface of the I-beam column 1. An electric wrench is placed on the surface of the first connector 411, causing the first connector 411 to drive the power screw 410 to rotate. The rotation of the power screw 410 causes the sliding plate 423 to slide laterally on the connecting plate 408. Through the transmission of the angle adjustment plate 407, the other end of the tilting plate 404 is rotated outward, adjusting the tilting plate 404 to the specified horizontal angle, so that the tilting plate 404... 04. Perpendicular to the tilt direction, when the width of the tilt fixing plate 2 is relatively wide, move the pulling rod 406 outward. According to the width of the tilt fixing plate 2, pull the telescopic plate 405 to a suitable length. After the telescopic plate 405 is stretched, weld the connection between the telescopic plate 405 and the tilt plate 404 to position the telescopic plate 405. Then, insert the lower adjusting rod 502 into the lower fixing tube 418 and align the upper adjusting rod 502 with the upper fixing tube 418. By rotating the adjusting screw ring 503, vertically adjust the position of the adjusting rod 502 so that the adjusting rod 502 is inserted into the corresponding fixing tube 418. Repeat this process. Several support sleeves 501 are fixed, and then a connecting groove 509 is opened according to the position of the rotating slip ring 506. Then, by moving the inclined fixing plate 2, the fixing buckle 420 is inserted into the fixing frame 419, and the inclined fixing plate 2 is fixed on the surface of the two inclined plates 404. The fixing nut 507 is rotated into the rotating slip ring 506. After being limited by the support washer 508, the inclined fixing plate 2 and the support sleeve 501 are fixed together. In this way, the inclined fixing plate 2 and the inclined direction are in the same straight line direction. The steel bar fixing sleeve 3 is used to fix the steel bar, which improves the stability of the steel bar fixing connection, reduces the welding difficulty of the connector, and improves the welding efficiency of the irregular steel section.
