Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and specifically to a steel structure connection device. Background Technology

[0002] Steel structures are building structures made primarily of steel. They offer advantages such as light weight, high strength, and convenient construction, and are widely used in projects such as large factories, stadiums, high-rise buildings, and bridges. Steel structures mainly consist of steel beams, steel columns, and steel trusses, which are typically connected by welding, bolts, or rivets.

[0003] In existing technologies, steel structure connections mostly adopt fixed connection methods, such as welding or rigid bolt connections, which makes it difficult to adjust the angles and positions between steel structures. Moreover, during actual construction, due to manufacturing errors, installation deviations, or site conditions, steel structure components may become misaligned or deviate at angles. In this case, traditional fixed connection methods cannot be flexibly adjusted, often requiring additional cutting, re-drilling, or component replacement, which not only increases the difficulty of construction but also affects project efficiency and quality. Utility Model Content

A wedge-shaped block that can move along the axial direction of the connecting cavity is provided at the bottom of the connecting cavity. A turntable is located at one end of the second steel structure and extends into the interior of the connecting cavity. The end face of the turntable is provided with a plurality of circumferentially distributed limiting grooves. The wedge block extends into one of the limiting grooves and is limited and engaged.

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] Combination Figures 1 to 6 As shown, this utility model provides a steel structure connection device, which is located at the connection between the first steel structure 1 and the second steel structure 2, and is used for adjusting the relative angle between the first steel structure 1 and the second steel structure 2.

[0019] The first steel structure 1 and the second steel structure 2 in this utility model are among the main structural types in the construction field. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of steel profiles and steel plates. Their surfaces are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing to ensure their durability and corrosion resistance. The steel structure connection device in this utility model can realize the angle adjustment and reliable connection between the first steel structure 1 and the second steel structure 2, effectively solving the problem of inconvenient adjustment during installation of traditional fixed connection methods.

[0020] In this utility model, the steel structure connection device may include a mounting base 302 and a turntable 305.

[0021] Specifically, the mounting base 302 is located inside the first steel structure 1. A circularly shaped connecting cavity 303 extending into the second steel structure 2 is provided on the side of the mounting base 302 closest to it. A wedge-shaped block 312, movable axially along the bottom of the connecting cavity 303, is provided at the bottom of the cavity. A turntable 305 is located at one end of the second steel structure 2 and extends into the connecting cavity 303. Multiple circumferentially distributed limiting grooves 307 are provided on the end face of the turntable 305. The wedge-shaped block 312 extends into one of the limiting grooves 307 and engages with it. One of the limiting grooves 307 is used to push the wedge surface of the wedge-shaped block 312 when the turntable 305 rotates, causing the wedge-shaped block 312 to move out of the limiting groove 307. This allows the first steel structure 1 and the second steel structure 2 to be adjusted and locked at a preset angle.

[0022] In some embodiments, a connecting plate 301 is provided on the side of the turntable 305 near the second steel structure 2.

[0023] Understandably, the mounting base 302 is pre-embedded in the cavity of the first steel structure 1 and fixed by welding or high-strength bolts. The connecting plate 301 can be fixed to one end of the second steel structure 2 by welding, bolt connection, or other methods. The turntable 305 and the connecting plate 301 can be fixed together by high-strength bolts or any suitable connection method known to those skilled in the art, ensuring that there is no relative rotation between the two.

[0024] The turntable 305 is circular, with a diameter slightly smaller than the inner diameter of the connecting cavity 303, to facilitate smooth insertion into the connecting cavity 303. Multiple limiting grooves 307 are evenly distributed on the end face of the turntable 305. The number and distribution angle of the limiting grooves 307 are designed according to actual angle adjustment requirements. For example, if adjustments to common angles such as 30°, 60°, and 90° are required, the limiting grooves 307 can be evenly distributed at 30° intervals. The size of the limiting grooves 307 corresponds to the wedge block 312. When the turntable 305 is inserted into the connecting cavity 303, the wedge block 312 can embed into a specific limiting groove 307, thereby achieving angle locking between the first steel structure 1 and the second steel structure 2. In some embodiments, at least six limiting grooves 307 are provided.

[0025] The wedge block 312 is configured to move axially along the connecting cavity 303. When the second steel structure 2 rotates under the action of external force, it drives the turntable 305 to rotate synchronously. The wedge surface of the wedge block 312 is configured such that its inclination direction forms an acute angle with the rotation direction of the turntable 305. The wedge surface of the wedge block 312 is squeezed, pushing the wedge block 312 to move away from the limiting groove 307. The wedge block 312 disengages from the limiting groove 307, releasing the angle lock. When the turntable 305 rotates to the required angle, the wedge block 312 moves towards the turntable 305 and engages with the corresponding limiting groove 307, thereby locking the first steel structure 1 and the second steel structure 2 at the predetermined angle.

[0026] Furthermore, combined Figure 3 and Figure 5 As shown, a resisting block 306 is also provided on the end face of the turntable 305, and a roller 308 is provided on the wedge side of the resisting block 306 facing the wedge surface of the wedge block 312. The roller 308 is mounted on the wedge side of the resisting block 306 facing the wedge block 312. In some embodiments, the roller 308 can be fixed to the resisting block 306 by a rotating shaft 304. The rotating shaft 304 and the resisting block 306 can be connected by welding, interference fit, or key connection to ensure that the roller 308 can rotate stably around the rotating shaft 304. The materials of the wedge block 312, the resisting block 306, and the roller 308 can be any high-strength, wear-resistant metal material known to those skilled in the art, and the surface is hardened to improve its wear resistance and service life.

[0027] During the angle adjustment process of the first steel structure 1 and the second steel structure 2, when the wedge block 312 contacts the resisting block 306 as the connecting plate 301 rotates, the wedge surface of the wedge block 312 contacts the roller 308 on the resisting block 306. Due to the presence of the roller 308, the relative motion between the wedge block 312 and the resisting block 306 changes from sliding friction to rolling friction, reducing friction and making the angle adjustment operation smoother, reducing wear, and thus extending the service life of the device.

[0028] In some embodiments, in order to improve the locking reliability under heavy loads, 2-4 wedge blocks 312 may be symmetrically arranged at the bottom of the connecting cavity 303.

[0029] Furthermore, in order to make the rotation of the turntable 305 more stable, multiple resisting blocks 306 can be provided, and the multiple resisting blocks 306 are evenly distributed in the circumferential direction among multiple limiting grooves 307.

[0030] In some embodiments, one or two resistance blocks 306 are provided between two adjacent limiting grooves 307 on the end face of the turntable 305. The total number of resistance blocks 306 can be two to three times the total number of wedge blocks 312. This arrangement can provide more uniform resistance when the turntable 305 rotates, avoiding local stress concentration. The resistance blocks 306 between adjacent limiting grooves 307 form "multi-point contact", making the turntable 305 rotate more smoothly and reducing jamming or jumping.

[0031] In some embodiments, the height of the resisting block 306 may be set to half the height of the wedge block 312 to avoid the resisting block 306 excessively interfering with the rotation of the turntable 305.

[0032] In this invention, a mounting groove 309 is provided at the bottom of the connecting cavity 303, and a spring 310 is provided at the bottom of the mounting groove 309. The end of the spring 310 away from the bottom of the groove is connected to the wedge block 312. Furthermore, a slidable movable plate 311 is also provided in the mounting groove 309, and the two ends of the movable plate 311 are respectively connected to the spring 310 and the wedge block 312.

[0033] The spring 310 is configured to provide stable elastic force to the wedge block 312, ensuring that the wedge block 312 can be embedded in the limiting groove 307 in its natural state. The elastic characteristics of the spring 310 can be selected and adjusted according to actual needs to meet the elastic force requirements in different connection scenarios.

[0034] The movable plate 311 makes the connection between the spring 310 and the wedge block 312 more stable and reliable. The sliding of the movable plate 311 in the mounting groove 309 ensures that the elastic force of the spring 310 is evenly transmitted to the wedge block 312, avoiding the eccentric force problem that may occur when the spring 310 is directly connected to the wedge block 312.

[0035] In the angle-locked state, the continuous elastic force of the spring 310 enables the wedge block 312 to be tightly embedded in the limiting groove 307, increasing the friction and clamping force between the wedge block 312 and the limiting groove 307, thereby improving the stability of the connection between the first steel structure 1 and the second steel structure 2 and effectively preventing the connection from loosening due to external vibration or force.

[0036] The size and shape of the mounting slot 309 can be set according to the specifications of the spring 310 and the movable plate 311 to ensure that the spring 310 and the movable plate 311 can be installed smoothly and work stably within the mounting slot 309. It is understood that the depth and width of the mounting slot 309 must ensure that the spring 310 has sufficient compression and extension space, while the movable plate 311 can slide freely within the mounting slot 309.

[0037] In some embodiments, the spring constant of spring 310 can be selected according to the required thrust and stroke of wedge block 312. One end of spring 310 is fixed to the bottom of mounting groove 309 by means of welding, bolting, or snap-fit ​​fixing, ensuring that spring 310 is firmly connected to the bottom of the groove and will not loosen under force. The other end of spring 310 is left free for connection with subsequently installed components.

[0038] One end of the movable plate 311 is connected to the end of the spring 310 away from the bottom of the groove. The connection method can be welding or fixing the two together with bolts to ensure that the elastic force of the spring 310 can be evenly transmitted to the movable plate 311.

[0039] One end of the wedge block 312 near the mounting groove 309 is connected to the other end of the movable plate 311. The connection can be made using bolts, snap-fit ​​connections, or other methods to ensure a reliable connection between the wedge block 312 and the movable plate 311, preventing separation under stress. At this time, the spring 310 applies a spring force to the wedge block 312 through the movable plate 311, extending it outwards from the connecting cavity 303, causing the wedge block 312 to extend into the limiting groove 307 in its natural state.

[0040] In this invention, a rotating shaft 304 is also connected between the turntable 305 and the second steel structure 2. Specifically, a bearing seat 6 is provided between the end of the rotating shaft 304 away from the second steel structure 2 and the inner wall of the connecting cavity 303. The rotating shaft 304 is connected to the inner wall of the connecting cavity 303 through the bearing seat 6, which provides accurate positioning for the rotating shaft 304 and ensures that the rotating shaft 304 does not deviate axially or radially during rotation.

[0041] In some embodiments, one end of the rotating shaft 304 can be fixed to the turntable 305 by means of key connection, interference fit, or welding. If a key connection is used, keyways need to be machined on both the rotating shaft 304 and the turntable 305, and a suitable key needs to be selected. After the key is inserted into the keyway, the turntable 305 is axially positioned by means of shaft shoulder or shaft end retaining ring to prevent the turntable 305 from moving axially on the rotating shaft 304.

[0042] In this invention, to further enhance the stability of the connection between the rigid structures, the outer periphery of the turntable 305 is provided with multiple circumferentially distributed threaded grooves 313, and the two sides of the first steel structure 1 are provided with fastening bolts 4 penetrating the mounting base 302. The fastening bolts 4 are engaged with the threaded grooves 313 for connection. The fastening bolts 4 are tightened in conjunction with the threaded grooves 313 on the turntable 305, which can further enhance the overall installation stability after the angle adjustment is completed, and prevent the connection angle from shifting due to external forces.

[0043] In this utility model, such as Figure 1 As shown, in order to enhance the strength of the steel structure, both the first steel structure 1 and the second steel structure 2 are welded with reinforcing plates 5, which can improve the strength and stability of the overall structure and make it more suitable for large buildings or complex load scenarios.

[0044] In summary, the specific implementation method of the steel structure connection device in this utility model is as follows: When the second steel structure 2 is rotated, the rotating shaft 304 drives the turntable 305 to rotate synchronously. The resisting block 306 on the turntable 305 pushes the wedge block 312 into the mounting groove 309 through the movable wheel, compressing the spring 310 and causing the wedge block 312 to disengage from the current limiting groove 307. When the turntable 305 rotates to the required angle, the wedge block 312 is engaged in the corresponding limiting groove 307 under the elastic force of the spring 310, and the preset angle is locked by the cooperation between the wedge block 312 and the limiting groove 307.

[0045] The steel structure connection device, through the cooperation of turntable 305, limiting groove 307 and wedge block 312, allows the second steel structure 2 to rotate along the axis of the rotating shaft 304 and lock at multiple preset angles, such as the 30° differential adjustment provided by no less than six limiting grooves 307. When the installation results in positional deviation, there is no need to cut the components. Simply rotate the second steel structure 2 to make the wedge block 312 disengage from the original limiting groove 307, rotate it to the appropriate angle, and then re-engage it to complete the adjustment. It is suitable for complex spaces or on-site rapid assembly scenarios.

[0046] After the first steel structure 1 and the second steel structure 2 are adjusted to the target angle through the steel structure connection device, they are connected by fastening bolts 4 and threaded grooves 313 to enhance the stability of the overall installation of the steel structure.
