Description
Technical Field
[0001] This utility model belongs to the field of steel structure installation technology, specifically an auxiliary connector for steel structure installation. Background Technology
[0002] Auxiliary connectors for steel structure installation are a type of general-purpose metal components specifically designed for steel structure construction. They achieve rapid positioning, temporary fixing, and precise connection between steel components through mechanical interlocking, elastic clips, or adjustable fixing methods. Their core function is to solve connection problems caused by component size deviations, space constraints, or construction errors during steel structure installation. These connectors are widely used in steel structure fields such as high-rise buildings, large stadiums, bridge projects, and industrial plants. They are particularly suitable for complex node connections, assembly of irregularly shaped components, and modular construction scenarios, which can significantly improve installation efficiency, reduce construction risks, and ensure the overall stability and safety of the structure. The operation of tightening auxiliary connectors for traditional steel structure installation is cumbersome, requires multiple people to work together, and relies on additional tools for temporary fixing, resulting in low construction efficiency, prominent safety hazards, and difficulty in meeting the needs of efficient modern steel structure construction. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an auxiliary connector for steel structure installation, which effectively solves the problems of cumbersome fastening operation of existing auxiliary connectors, the need for multiple people to work together, and the reliance on additional tools for temporary fixing, resulting in low construction efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary connector for steel structure installation, including an installation frame, an alignment bucket fixedly installed at one end of the installation frame, an opening at the bottom of both the installation frame and the alignment bucket, the alignment bucket being outwardly expanding, installation grooves on both inner walls of the installation frame, clamping plates inside the two installation grooves, a handwheel at the top of the installation frame, a rotating shaft fixedly installed at the bottom of the handwheel, a bearing rotatably installed on the surface of the rotating shaft, and the surface of the bearing being fixedly connected to the top of the installation frame through a support frame; The bottom of the rotating shaft is equipped with a transmission component, which is connected to two clamping plates. When the rotating shaft rotates, the transmission component drives the two clamping plates to move towards each other for clamping.
[0005] Preferably, the transmission assembly includes a lead screw fixedly mounted at the bottom of the rotating shaft, the bottom end of the lead screw being rotatably connected to the top of the mounting frame via a bearing seat, and a threaded sleeve being threaded onto the surface of the lead screw.
[0006] Preferably, a support arm is fixedly installed on the surface of the thread sleeve, and a push bar is fixedly installed at both ends of the support arm, with the lower ends of the two push bars being inclined.
[0007] Preferably, both sides of the two push bars are fixedly installed with slide bars by connecting plates, and two slide grooves are opened on both sides of the mounting frame, and the four slide bars are slidably installed inside the four slide grooves.
[0008] Preferably, the inclined surfaces at the lower ends of the two push bars are closely attached to the contact heads, and the two contact heads are fixedly installed with insert rods on the side that is close to each other. Insert holes are opened in the middle of both sides of the mounting frame, and the two insert rods are movably inserted into the two insert holes. The ends of the two insert rods that are close to each other are fixedly connected to the two clamps. Springs are sleeved on the surface of the insert rods, and the two ends of the two springs are fixedly connected to the contact heads and the mounting frame, respectively.
[0009] Preferably, each of the four corners of the two clamping plates on the side furthest from each other is fixedly equipped with a sliding rod, and each of the eight sliding rods is fitted with a sliding sleeve, and the surfaces of the eight sliding sleeves are respectively fixedly installed on both sides of the mounting frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator puts the installation frame on the end of the steel column and makes the alignment bucket extend to the outside of one end of the steel column. Then, the operator drives the rotating shaft to rotate through the handwheel. When the rotating shaft rotates, the screw drives the screw sleeve to rotate. When the screw sleeve rotates, the support arm drives the two pushing bars to move down. When the two pushing bars move down, the four connecting plates drive the four sliding bars to slide inside the four sliding grooves, which increases the stability of the two pushing bars when they move. When the two pushing bars move downwards, they simultaneously push the two contact heads to move towards each other. As the contact heads move, they cause the two insert rods to slide towards each other inside the two insertion holes, simultaneously compressing the two springs. The movement of the two insert rods towards each other causes the two clamping plates to move towards each other. Each clamping plate, in turn, causes the sliding rod to slide inside the sliding sleeve, increasing the stability of the two clamping plates during movement. When the two clamping plates move towards each other, they clamp onto the steel column, thus quickly completing the installation of the mounting frame and alignment bucket. When the steel columns are joined, the operator quickly inserts another steel column into the mounting frame along the alignment bucket, ensuring precise alignment of the connecting bolts and connecting holes on the two steel columns, thereby assisting in the rapid installation of the steel columns. This allows the auxiliary connectors for steel structure installation to be quickly fastened to the ends of the steel columns, enabling one person to complete the installation without relying on additional tools, thereby improving construction efficiency and meeting the needs of efficient modern steel structure construction.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] Depend on Figures 1 to 4 The present invention includes an installation frame 1, an alignment bucket 2 fixedly installed at one end of the installation frame 1, and openings at the bottom of both the installation frame 1 and the alignment bucket 2, through which the installation frame 1 and the alignment bucket 2 can be fitted onto the end of the steel column. The alignment bucket 2 is outwardly expanding to facilitate the alignment of the two steel columns. Installation grooves 4 are provided on both inner walls of the installation frame 1, and clamping plates 5 are provided inside the two installation grooves 4 to hold the steel column. A handwheel 3 is provided on the top of the installation frame 1, and a rotating shaft 8 is fixedly installed at the bottom of the handwheel 3. A bearing 9 is rotatably installed on the surface of the rotating shaft 8, and the bearing 9 can rotate and position the rotating shaft 8. The surface of the bearing 9 is fixedly connected to the top of the installation frame 1 through a support frame 10. The bottom of the rotating shaft 8 is equipped with a transmission component, which is connected to the two clamping plates 5. When the rotating shaft 8 rotates, the transmission component drives the two clamping plates 5 to move towards each other for clamping.
[0015] In use, the operator places the installation frame 1 onto the end of the steel column and extends the alignment bucket 2 to the outside of one end of the steel column. Then, the operator drives the rotating shaft 8 to rotate via the handwheel 3. When the rotating shaft 8 rotates, it drives the two clamping plates 5 to move towards each other through the transmission assembly. When the two clamping plates 5 move towards each other, they clamp onto the steel column, thus quickly completing the installation of the installation frame 1 and the alignment bucket 2. When the steel columns are joined, the operator quickly inserts another steel column into the installation frame 1 along the alignment bucket 2, so that the connecting bolts and connecting holes on the two steel columns are precisely aligned, thereby assisting in the rapid installation of the steel columns. This allows the auxiliary connector for steel structure installation to be quickly fastened to the end of the steel column, and one person can complete the installation without relying on additional tools, thereby improving construction efficiency and meeting the needs of efficient modern steel structure construction.
[0016] The transmission assembly includes a lead screw 11 fixedly mounted at the bottom of the rotating shaft 8. The bottom end of the lead screw 11 is rotatably connected to the top of the mounting frame 1 via a bearing seat 13. The bearing seat 13 can rotate and position the lead screw 11 to ensure the stability of the lower end when the lead screw 11 rotates. A threaded sleeve 12 is threaded onto the surface of the lead screw 11. Rotation of the lead screw 11 can cause the threaded sleeve 12 to move vertically on its surface. A support arm 14 is fixedly mounted on the surface of the threaded sleeve 12. Pushing bars 15 are fixedly mounted on both ends of the support arm 14. The lower ends of the two pushing bars 15 are inclined to facilitate the pushing transmission of the two pushing bars 15. Slides 17 are fixedly installed on both sides of the two push bars 15 via connecting plates 16. Two slide grooves 18 are opened on both sides of the mounting frame 1. The four slide bars 17 are slidably installed inside the four slide grooves 18, so that the slide bars 17 can slide in the slide grooves 18 to limit the movement trajectory of the two push bars 15.
[0017] When the rotating shaft 8 rotates, it drives the threaded sleeve 12 to rotate through the lead screw 11. When the threaded sleeve 12 rotates, it drives the two push bars 15 to move down through the support arm 14. When the two push bars 15 move down, they drive the four slide bars 17 to slide inside the four slide grooves 18 through the four connecting plates 16, which increases the stability of the two push bars 15 when they move.
[0018] The inclined surfaces at the lower ends of the two push bars 15 are closely attached to the contact heads 19. The two contact heads 19 are fixedly installed with plug rods 20 on the side that is close to each other. The middle of both sides of the mounting frame 1 is provided with plug holes 22. The two plug rods 20 are movably inserted into the two plug holes 22, so that the two plug rods 20 can move within the two plug holes 22. The ends of the two plug rods 20 that are close to each other are fixedly connected to the two clamping plates 5. The surface of the plug rods 20 is covered with springs 21. The two ends of the two springs 21 are fixedly connected to the contact head 19 and the mounting frame 1 respectively. When the two springs 21 release their elastic potential energy, they can push the two clamping plates 5 to move and reset. Each of the four corners of the two clamping plates 5, which are far apart from each other, is fixedly installed with a sliding rod 7. Each of the eight sliding rods 7 is fitted with a sliding sleeve 6, which allows the sliding rod 7 to move within the sliding sleeve 6, thereby limiting the movement trajectory of the two clamping plates 5. The surfaces of the eight sliding sleeves 6 are respectively fixedly installed on both sides of the mounting frame 1.
[0019] When the two pushing bars 15 move downward, they will simultaneously push the two contact heads 19 to move towards each other. When the two contact heads 19 move, they will drive the two insert rods 20 to slide towards each other inside the two insertion holes 22, and at the same time compress the two springs 21. When the two insert rods 20 move towards each other, they will drive the two clamping plates 5 to move towards each other. When the two clamping plates 5 move, they will drive the sliding rod 7 to slide inside the sliding sleeve 6, which will increase the stability of the two clamping plates 5 when they move. When the two clamping plates 5 move towards each other, they will clamp onto the steel column, thereby quickly completing the installation of the installation frame 1 and the alignment bucket 2.
