Description

Technical Field

[0001] This invention relates to the field of steel structure connection construction technology, and in particular to a connection tooling and its usage method for steel structure construction. Background Technology

[0002] Steel structures are one of the main types of building structures. They are mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates. They undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets.

[0003] In multi-story and high-rise buildings, steel structures often need to be spliced ​​in the air depending on the site conditions. This typically involves connecting horizontal steel members between two vertical steel members using bolts. When fixing the horizontal steel members, a crane lifts them to their positions. Then, when connecting the steel structures, a worker needs to adjust and position the ends to ensure they are horizontal. Due to the large number of degrees of freedom in adjustment, the accuracy is poor and the process is slow, resulting in prolonged high-altitude work and increased safety hazards. Then, another worker tightens the bolts. During the adjustment and positioning of the steel members, the horizontal steel members are prone to swaying, making the connection difficult. Furthermore, bolts can easily fall during tightening, leading to falling objects and posing a significant safety hazard. Therefore, researching a new connection tool and its application method for steel structure construction to solve these problems is of great significance. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Therefore, the technical problem to be solved by the present invention is that when connecting steel structures, due to the large number of degrees of freedom in the adjustment, the adjustment accuracy is poor and the adjustment is slow, resulting in a long working time at height. Moreover, during the tightening of bolts, bolts are prone to falling off, which can lead to falling objects from heights and pose a significant safety hazard.

[0008] As a further aspect of the present invention: a magnet and a pad are fixedly connected above the cavity seat, and the magnet and the pad are respectively connected to two steel structures.

[0009] As a further aspect of the present invention: the flip-up receiving component includes a frame, a mesh belt is fixedly connected to the lower part of the frame, and one side of the mesh belt is fixedly connected to the cavity seat;

[0010] The same rotating shaft is installed at both ends of the frame, and a roller is fixedly connected to the rotating shaft. The arc-shaped groove is opened on the roller. Both ends of the rotating shaft are rotatably connected to two fixed blocks through bearings. The two fixed blocks are fixedly connected to the cavity seat.

[0011] As a further aspect of the present invention: the driving assembly includes a motor, the motor is fixedly installed in the cavity, and the output shaft of the motor is fixedly connected to a frame plate.

[0012] As a further embodiment of the present invention: the translational transmission assembly includes a support bar, on which a roller is fixedly connected, the roller being located in a frame plate, and toothed plates are fixedly connected to both ends of the support bar. The toothed plates slide on the cavity seat, and both sides of the toothed plates are fixedly connected to two drive rods respectively. The drive rods pass through an opening, which is opened on the cavity seat.

[0013] As a further embodiment of the present invention: guide strips are provided on both the upper and lower sides of the toothed plate, the guide strips are fixedly connected to the side wall of the cavity seat, and the toothed plate slides on the two guide strips.

[0014] As a further aspect of the present invention: the rotational transmission assembly includes a connecting shaft, which is rotatably connected to the cavity seat via a bearing. A gear is fixedly connected to the bottom end of the connecting shaft, and the gear meshes with a gear plate. A fixing strip is fixedly connected to the top end of the connecting shaft, and the fixing strip is fixedly connected to the connecting cylinder.

[0015] As a further aspect of the present invention: the pressing assembly includes a second piston, which is disposed in a connecting cylinder, and a ball bearing rod is fixedly connected below the second piston, the ball bearing rod being pressed down and fitted against the edge of the steel structure.

[0016] As a further aspect of the present invention: the elastic component includes a first piston, a connecting column is fixedly connected to the lower part of the first piston, a ball is fixedly connected to the bottom end of the connecting column, the ball rests on an arc plate, a spring is fixedly connected between the lower part of the first piston and the port wall of the connecting cylinder, and the connecting cylinder is filled with liquid.

[0017] A method for using a butt-jointing fixture in steel structure construction includes the following steps:

[0018] S1. When connecting steel structures, the steel structures are attracted to one of the steel structures by magnets, and then the two steel structures are connected. The motor is then controlled to run, and the motor drives the frame plate to rotate. The frame plate drives the rollers to move, which in turn causes the frame plate to press the rollers to move the support bars. The support bars drive the toothed plate to move, and the toothed plate meshes with the gears to drive the connecting shaft to rotate. The connecting shaft drives the fixing bars and connecting cylinder to rotate, which in turn causes the connecting cylinder to drive the side wheels to rotate and fit against the steel structure. The side wheels on both sides can press the steel structure to move horizontally and center, keeping the two steel structures aligned. The ball bearings rotate and move to the position of the arc plate, which causes the arc plate to press the ball bearings upward. The ball bearings drive the first piston upward through the connecting column, which in turn controls the second piston to move downward by squeezing the liquid. The second piston pushes the ball bearing rod downward to press against the lower edge of the steel structure and fix it.

[0019] S2. Secondly, when the toothed plate moves in translation, the toothed plate drives the drive rod to move. The drive rod moves along the arc groove, and the drive rod squeezes the roller body to rotate through the arc surface of the arc groove. The roller body drives the rotating shaft to rotate, the rotating shaft drives the frame to rotate, and the frame drives the mesh belt to flip and unfold. Then, when bolting the two steel structures, the mesh belt catches the fallen fasteners.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The steel structure construction docking fixture and its usage method involve a motor driving the frame plate to rotate, which in turn causes the frame plate to control the rollers to move horizontally. The rollers, through the support bars, drive the toothed plate to move horizontally. The toothed plate meshes with the gears, which in turn drive the fixing bars and connecting cylinders to rotate through the connecting shaft. This causes the connecting cylinders to drive the side wheels to turn towards the steel structure, allowing the side wheels on both sides to simultaneously push the steel structure to achieve centering. This prevents the steel structure from deviating and ensures precise docking of the two steel structures. It also allows for rapid docking of two steel structures, improving docking accuracy and adjustment speed, reducing the time spent working at height, and lowering safety hazards. Furthermore, by automatically aligning the two steel structures, it reduces construction difficulty and thus improves construction efficiency.

[0022] 2. The steel structure construction docking fixture and its usage method are as follows: The frame plate is driven by a motor to move, which allows the frame plate to compress the ball bearings and move them horizontally. The ball bearings drive the support bar to move, and the support bar drives the toothed plate to move and mesh with the gear. The gear drives the connecting shaft to rotate, and the connecting shaft drives the connecting cylinder to move through the fixing bar. This allows the side wheels on both sides to achieve the centering operation of the steel structure, ensuring the precise docking of the two steel structures. The ball bearings move upward under the pressure of the arc surface of the arc plate. The connecting plate drives the first piston to move upward, and the liquid pushed on the first piston drives the second piston to move. The second piston pushes the ball bearing rod downward, and the ball bearing rod presses against the lower edge of the steel structure. This allows the side wheels and the ball bearing rod to limit the movement of the steel structure, prevent the steel structure from moving, and maintain the precise docking of the two steel structures.

[0023] 3. The steel structure construction docking fixture and its usage method involve a motor-driven frame plate rotation. The frame plate presses the rollers and support bars, causing the toothed plate to move and drive the drive rod. The drive rod can then press the roller through the arc surface of the arc groove, causing it to rotate. The roller drives the rotating shaft to rotate, and the rotating shaft, through the frame, drives the mesh belt to unfold. This unfolding of the mesh belt increases the catching area, allowing for the catching of accidentally dropped fixed parts during steel structure installation. This prevents injuries from falling objects from heights and reduces safety hazards. Attached Figure Description

[0043] Example 1

[0044] like Figure 1-6 and Figure 5-11As shown, the present invention provides a technical solution: a docking fixture for steel structure construction, including a cavity seat 100. A magnet 400 and a pad 116 are fixedly connected to the upper part of the cavity seat 100. The magnet 400 and the pad 116 overlap with two steel structures 200 respectively. The magnet 400 can strongly adhere to the steel surface of the steel structure 200, thereby fixing the cavity seat 100. The pad 116 can support the steel structure 200 and maintain the docking of the two steel structures 200. Two steel structures 200 are provided above the cavity seat 100. A drive assembly 700 is fixedly installed in the middle of the cavity of the cavity seat 100. The drive assembly 700 includes a motor 701, which is fixedly installed in the cavity seat 100. The output shaft of the motor 701 is fixedly connected to a frame. The frame plate 702 has holes on both sides, allowing it to smoothly rotate and drive the rollers 502 for translational movement, thus enabling the toothed plate 503 to translate. Both sides of the drive assembly 700 are connected to translational transmission assemblies 500, each including a support bar 501 with rollers 502 fixedly connected to it. The rollers 502 have rolling properties to reduce frictional resistance with the frame plate 702, ensuring smooth movement. The rollers 502 are located within the frame plate 702. Toothed plates 503 are fixedly connected to both ends of the support bar 501, sliding along the cavity seat 100. Each side of the toothed plate 503 is fixedly connected to two drive rods 113, which protrude from the openings. 115. The opening 115 provides space for the drive rod 113 to move smoothly and extend into the arc-shaped groove 114. The opening 115 is formed on the cavity seat 100. Guide bars 504 are provided on both the upper and lower sides of the toothed plate 503. The guide bars 504 are fixedly connected to the side wall of the cavity seat 100, and the toothed plate 503 slides on the two guide bars 504. The guide bars 504 not only support the toothed plate 503, but also guide the toothed plate 503 to maintain its smooth movement. The translational transmission assembly 500 slides through the cavity seat 100. Two rotary transmission assemblies 800 are meshed on both sides of the translational transmission assembly 500. The rotary transmission assembly 800 includes a connecting shaft 80 2. The connecting shaft 802 is rotatably connected to the cavity seat 100 via bearings. The bearings can fix the connecting shaft 802 and reduce the rotational resistance of the connecting shaft 802, allowing it to rotate smoothly. A gear 801 is fixedly connected to the bottom end of the connecting shaft 802. The gear 801 meshes with the gear plate 503. Through the translational movement of the gear plate 503 and its meshing with the gear 801, the gear 801 can drive the connecting shaft 802 to rotate. A fixing strip 803 is fixedly connected to the top end of the connecting shaft 802. The fixing strip 803 is fixedly connected to the connecting cylinder 111. The fixing strip 803 can fix the connecting cylinder 111 and support both ends of the connecting cylinder 111 to maintain its stability. The rotational transmission assembly 800 is installed inside the cavity seat 100.A U-shaped connecting cylinder 111 is fixedly connected to the top of the rotating transmission assembly 800. Two side wheels 110 are fixedly connected to one side of the connecting cylinder 111. The rolling of the side wheels 110 reduces the frictional resistance between the cylinder and the steel structure 200, thus allowing the steel structure 200 to be smoothly pushed for centering. The two side wheels 110 are positioned between themselves and the steel structure 200. A pressing assembly 900 and an elastic assembly 600 are respectively located in the two internal ports of the connecting cylinder 111. The pressing assembly 900 presses against the lower edge of the steel structure 200. An arc-shaped plate 112 is mounted on the bottom of the elastic assembly 600. The arc surface of the arc plate 112 allows the ball bearings 601 to... The roller smoothly moves along the arc-shaped plate 112, and as the arc surface of the arc-shaped plate 112 increases in height, it can press against the connecting column 603. The arc-shaped plate 112 is fixedly connected above the cavity seat 100. A flip-up receiving assembly 300 is fixedly connected to both sides of the cavity seat 100. Two arc-shaped grooves 114 are formed on the flip-up receiving assembly 300. A drive rod 113 is slidably connected within the arc-shaped groove 114. The movement of the drive rod 113 causes it to move along the arc-shaped groove 114, and the arc surface of the arc-shaped groove 114 compresses the roller 303 to achieve rotational movement. Every two drive rods 113 are fixedly connected to the translation transmission assembly 500.

[0045] In this embodiment, the frame plate 702 is driven to rotate by the motor 701, which in turn controls the roller 502 to achieve translational movement. The roller 502 drives the toothed plate 503 to translate through the support bar 501. The toothed plate 503 meshes with the gear 801 for transmission. The gear 801 drives the fixing bar 803 and the connecting cylinder 111 to rotate through the connecting shaft 802. This causes the connecting cylinder 111 to drive the side wheel 110 to turn towards the steel structure 200. The side wheels 110 on both sides simultaneously apply force to push the steel structure 200 to achieve centering, preventing the steel structure 200 from deviating and ensuring precise docking of the two steel structures 200. Moreover, it allows for rapid docking of the two steel structures 200, improving docking accuracy and adjustment speed, reducing the time spent working at height, and lowering safety hazards. Furthermore, by automatically aligning the two steel structures 200, the construction difficulty is reduced, thereby improving construction efficiency.

[0046] Example 2

[0047] Combined with appendix Figure 5 Appendix Figure 9 and attached Figure 11 Therefore, it is concluded that the drive assembly 700 includes a motor 701, which is fixedly installed in the cavity seat 100, and the output shaft of the motor 701 is fixedly connected to the frame plate 702.

[0048] The translational transmission assembly 500 includes a support bar 501, on which a roller 502 is fixedly connected. The roller 502 is located in the frame plate 702. Both ends of the support bar 501 are fixedly connected to toothed plates 503. The toothed plates 503 slide on the cavity seat 100. Both sides of the toothed plates 503 are fixedly connected to two drive rods 113 respectively. The drive rods 113 pass through an opening 115, which is opened on the cavity seat 100.

[0049] The flip-up receiving component 300 includes a frame 301, through which a mesh belt 302 is connected. Flipping the frame 301 can cause the mesh belt 302 to unfold, increasing the receiving area and preventing fixed parts from falling during high-altitude operations. The mesh belt 302 is fixedly connected to the bottom of the frame 301, and can catch falling fixed parts through the mesh belt 302 to prevent them from falling. One side of the mesh belt 302 is fixedly connected to the cavity seat 100. The same rotating shaft 304 is installed through both ends of the frame 301. A roller body 303 is fixedly connected to the rotating shaft 304. An arc-shaped groove 114 is opened on the roller body 303. Both ends of the rotating shaft 304 are rotatably connected to two fixed blocks 305 through bearings. The fixed blocks 305 can fix the bearings, so that the bearings can support the rotating shaft 304, and the rotating shaft 304 can maintain stable rotation through the bearings. The two fixed blocks 305 are fixedly connected to the cavity seat 100.

[0050] In this embodiment: the frame plate 702 is driven to rotate by the motor 701. The frame plate 702 squeezes the roller 502 and the support strip to translate, causing the toothed plate 503 to translate and drive the drive rod 113 to move. The drive rod 113 can squeeze the roller 303 to rotate through the arc surface of the arc groove 114. The roller 303 drives the rotating shaft 304 to rotate. The rotating shaft 304 drives the mesh belt 302 to unfold through the frame 301. After the mesh belt 302 is unfolded, the receiving area is increased. When installing the steel structure 200, it can catch the fixed parts that are accidentally dropped, thereby avoiding the problem of falling objects from heights and reducing safety hazards.

[0051] Example 3

[0052] Combined with appendix Figure 9-13 Therefore, it is concluded that the drive assembly 700 includes a motor 701, which is fixedly installed in the cavity seat 100, and the output shaft of the motor 701 is fixedly connected to the frame plate 702.

[0053] The translational transmission assembly 500 includes a support bar 501, on which a roller 502 is fixedly connected. The roller 502 is located in the frame plate 702. Both ends of the support bar 501 are fixedly connected to toothed plates 503. The toothed plates 503 slide on the cavity seat 100. Both sides of the toothed plates 503 are fixedly connected to two drive rods 113 respectively. The drive rods 113 pass through an opening 115, which is opened on the cavity seat 100.

[0054] The rotary transmission assembly 800 includes a connecting shaft 802, which is rotatably connected to the cavity seat 100 via a bearing. A gear 801 is fixedly connected to the bottom end of the connecting shaft 802, and the gear 801 meshes with the gear plate 503. A fixing strip 803 is fixedly connected to the top end of the connecting shaft 802, and the fixing strip 803 is fixedly connected to the connecting cylinder 111.

[0055] The pressing assembly 900 includes a second piston 901. The second piston 901 is sealed with the inner wall of the connecting cylinder 111 to prevent leakage. The second piston 901 is located in the connecting cylinder 111. A ball rod 902 is fixedly connected below the second piston 901. The ball rod 902 is pressed down and fits against the edge of the steel structure 200.

[0056] The elastic component 600 includes a first piston 604, which maintains the sealing of the inner wall of the connecting cylinder 111 to prevent leakage and pushes the liquid to move, thus smoothly controlling the movement of the second piston 901. A connecting post 603 is fixedly connected below the first piston 604, and a ball bearing 601 is fixedly connected to the bottom end of the connecting post 603. The ball bearing 601 reduces the frictional resistance between itself and the arc-shaped plate 112, allowing the ball bearing 601 to move smoothly. A spring 602 is fixedly connected between the lower part of the first piston 604 and the port wall of the connecting cylinder 111 on the arc plate 112. The elastic force of the spring 602 can drive the first piston 604 to return to its original position downwards. The first piston 604 drives the connecting column 603 to return to its original position downwards. Then, the first piston 604 can introduce liquid, thereby controlling the second piston 901 to lift the ball rod 902, so that the ball rod 902 removes the restriction on the steel structure 200, and the connecting cylinder 111 is filled with liquid.

[0057] In this embodiment: the frame plate 702 is driven to move by the motor 701, causing the frame plate 702 to compress the ball bearing 601 and move it in a translational motion. The ball bearing 601 drives the support bar 501 to move, and the support bar 501 drives the toothed plate 503 to move and mesh with the gear 801 for transmission. This causes the gear 801 to drive the connecting shaft 802 to rotate, and the connecting shaft 802 drives the connecting cylinder 111 to move through the fixing bar 803. This allows the side wheels 110 on both sides to achieve the centering operation of the steel structure 200, ensuring the precise alignment of the two steel structure 200s. The two steel structures 200 are connected, and the ball bearing 601 moves and is squeezed upward by the arc surface of the arc plate 112. The connecting plate drives the first piston 604 to move upward. The liquid pushed on the first piston 604 drives the second piston 901 to move, so that the second piston 901 pushes the ball rod 902 downward. The ball rod 902 is pressed against the lower edge of the steel structure 200, so that the side wheel 110 and the ball rod 902 can limit the steel structure 200, prevent the steel structure from moving, and maintain the precise connection of the two steel structures 200.

[0058] A method for using a butt-jointing fixture in steel structure construction includes the following steps:

[0059] S1. During the docking of steel structures 200, magnets 400 are used to attract one of the steel structures 200. Then, the two steel structures 200 are docked. Motor 701 is then activated, causing the frame plate 702 to rotate. The frame plate 702 drives the roller 502, which in turn presses against the roller 502, causing the support bar 501 to move. The support bar 501 then drives the toothed plate 503, which meshes with the gear 801. This causes the gear 801 to rotate the connecting shaft 802, which in turn rotates the fixing bar 803 and the connecting cylinder 111. The connecting cylinder 111 drives the side wheel 110 to rotate and fit against the steel structure. The side wheels 110 on both sides can squeeze the steel structure 200 to translate and center, keeping the two steel structures 200 aligned. The ball 601 rotates and moves to the position of the arc plate 112, so that the arc plate 112 squeezes the ball 601 to move upward. The ball 601 drives the first piston 604 to move upward through the connecting column 603. The first piston 604 controls the second piston 901 to move downward by squeezing the liquid. The second piston 901 pushes the ball rod 902 downward to press it against the lower edge of the steel structure 200 and fix it.
