Description

Technical Field

[0001] This utility model relates to the field of steel structure connection construction technology, specifically to the adaptive adjustment connection construction of complex steel structures. Background Technology

[0002] Steel structure connectors are indispensable key components in building, bridge, and other engineering projects, and their performance directly affects the stability and safety of the overall structure. Traditional connection methods mainly include welding and bolting. These two technologies are widely used due to their mature processes and high reliability, providing basic solutions and playing an important role in promoting the development of modern architecture.

[0003] However, traditional connection methods have significant shortcomings in practical applications. First, they require extremely high construction precision; any deviation in layout or installation often necessitates rework, which is not only time-consuming and labor-intensive but may also compromise structural safety. Second, existing connectors lack effective adjustment capabilities, making it difficult to adapt to angle changes or construction errors in complex steel structures, resulting in low installation efficiency. Furthermore, welding operations pose safety hazards and are costly. These problems severely restrict the quality and efficiency of steel structure construction, necessitating a more flexible and reliable connection technology to address these issues. Summary of the Invention

[0004] (I) Technical problems to be solved: In view of the shortcomings of the existing technology, this utility model provides a connection structure for complex steel structures that is self-adjustable, with adjustable horizontal displacement and omnidirectional angle adaptation, which solves the problems of poor adjustment capability, high construction accuracy requirements and low installation efficiency of traditional steel structure connectors.

[0005] (II) Technical Solution: To achieve the above-mentioned purpose of adjustable horizontal displacement and omnidirectional angle adaptation, this utility model provides the following technical solution: a connection structure for adaptive adjustment of complex steel structures, including a clamp, a connector, and an adjuster. The clamp is generally arc-shaped with a fixing groove on its outer surface, through which it is connected to the steel structure. One end of the connector is fixedly connected to the clamp, and the fixed end is the upper end of the connector.

[0006] The outer surface of the side end of the connector is provided with a first waist-shaped groove, which penetrates the connector. The upper and lower sides of the first waist-shaped groove are provided with second waist-shaped grooves at equal intervals. The first waist-shaped groove and the second waist-shaped groove are designed to be parallel and perpendicular to the arc axis of the clamp.

[0007] The outer surface of the adjusting component is provided with a fixing hole, and at least six adjusting holes are arranged in a circle around the fixing hole. The fixing hole is fixedly connected to the first waist-shaped groove, and at least two of the adjusting holes are fixedly connected to the second waist-shaped groove. A fixing plate is provided at the bottom of the adjusting component, and the fixing plate is fixedly connected to the panel material.

[0008] Preferably, both the fixing hole and the adjusting hole are fixedly connected to the first waist-shaped groove or the second waist-shaped groove by bolts.

[0009] Preferably, the length of the first waist-shaped groove is greater than that of the second waist-shaped groove, and the second waist-shaped groove is symmetrically distributed at the upper and lower ends of the first waist-shaped groove.

[0010] Preferably, the diameter of the fixing hole is larger than that of the adjusting hole, and the diameter of the adjusting hole is smaller than the width of the second waist-shaped groove.

[0011] Preferably, the second waist-shaped groove is a blind groove.

[0012] Preferably, the fixing plate and the adjusting member are an integral structure, and the fixing plate and the adjusting member are vertically distributed.

[0013] Preferably, the end face of the connector away from the clamp is a curved surface, and the end face of the adjusting member near the connector is also a curved surface.

[0014] Preferably, the fixing groove extends along the circumferential direction of the clamp, and the fixing groove is an oblong groove.

[0015] (III) Beneficial Effects: Compared with the prior art, this utility model provides an adaptive adjustment connection structure for complex steel structures, which has the following beneficial effects:

[0016] 1. The adaptive adjustment connection structure of this complex steel structure achieves horizontal linear displacement adjustment of the panel material through the through first waist-shaped groove, eliminating the accumulation of on-site errors, ensuring construction accuracy, and improving construction efficiency; through the non-through second waist-shaped groove, combined with the radially arranged circular holes around the center point on the panel connecting ear plate, 360° omnidirectional angle adaptation is achieved, meeting the spatial load-bearing requirements of complex steel structures. This solves the problems of existing construction methods, such as the inability to adjust horizontal depth, cumbersome spatial angle adjustment operations, large workload, inability to effectively absorb and eliminate construction deviations, and high construction costs.

[0017] 2. This complex steel structure's adaptive adjustment connection design, by using a blind slot structure for the second oblong hole, avoids the cross-sectional weakening caused by through slots. This ensures that when the adjusting bolts are tightened, the second oblong slot can resist the shear force transmitted by the panel material, preventing deformation of the slot edge. Furthermore, the bottom of the blind slot can act as a limiting surface to restrict excessive bolt displacement, ensuring uniform pressure between the bolt head and the slot bottom during angle adjustment. The blind slot structure design guarantees both adjustment guidance accuracy and final locking stiffness. Simultaneously, the phased operation process allows construction personnel to effectively absorb construction errors, adapting to the installation requirements of complex steel structures. This adaptive adjustment characteristic makes this structure particularly suitable for special architectural forms such as curved curtain walls and irregularly shaped roofs, which are difficult to handle with traditional connection methods.

[0018] 3. This complex steel structure's self-adjusting connection structure, through the design of clamps, connectors, and adjusters, achieves the advantages of simple structural construction and convenient operation. Compared with existing technologies, which often involve accurately laying out the panel material and then connecting the steel structure connector to the end connecting plate of the panel material using screws and welding or three sets of bolts, existing technologies suffer from high requirements for measurement and layout accuracy, difficult construction operations, numerous welding operations, and challenging safety measures. In contrast, the clamps, connectors, and adjusters of this invention use standardized prefabricated components, ensuring component accuracy through machining. On-site installation only requires bolt assembly, avoiding the welding operations of traditional processes. The waist-shaped groove on the connector and the radial hole group on the adjuster form a positioning system, allowing construction personnel to quickly position the panel. The one-piece molded fixing plate design allows the panel material to be directly installed with self-tapping screws, significantly reducing assembly steps compared to traditional ear plate connection methods. This structure significantly improves construction efficiency and is particularly suitable for engineering scenarios requiring rapid installation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-2 The complex steel structure adaptive adjustment connection structure includes a clamp 1, a connector 2, and an adjuster 3. The clamp 1 is generally arc-shaped, and a fixing groove 11 is provided on its outer surface. The fixing groove 11 extends along the circumference of the clamp 1 and is a waist-shaped groove. The clamp 1 is connected to the steel structure 5 through the fixing groove 11 and bolts. One end of the connector 2 is fixedly connected to the clamp 1. In this embodiment, the connection is fixed by welding, and the welded end is the upper end of the connector 2.

[0031] Please see Figure 3 The outer surface of the side end of the connector 2 is provided with a first waist-shaped groove 21, which penetrates the connector 2. The upper and lower sides of the first waist-shaped groove 21 are provided with second waist-shaped grooves 22 at equal intervals. The second waist-shaped grooves 22 are blind grooves to avoid the weakening of the cross section caused by the through groove. This ensures that when the adjusting bolt is tightened, the second waist-shaped grooves 22 can resist the shear force transmitted by the panel material 4, prevent the groove edge from deforming, and the bottom of the blind groove can be used as a limiting surface to limit the excessive displacement of the bolt and ensure that the pressure between the bolt head and the bottom of the groove is uniform when the angle is adjusted. The length of the first waist-shaped groove 21 is greater than that of the second waist-shaped groove 22. The second waist-shaped grooves 22 are symmetrically distributed at the upper and lower ends of the first waist-shaped groove 21. The first waist-shaped groove 21 and the second waist-shaped groove 22 are designed to be parallel and perpendicular to the arc axis of the clamp 1.

[0032] Please see Figure 4The adjusting component 3 has a fixing hole 31 on its outer surface. Around the fixing hole 31, at least six adjusting holes 32 are arranged in a circular array around its circumference. In this embodiment, there are eight. The fixing hole 31 is fixedly connected to the first waist-shaped groove 21 by bolts, and at least two adjusting holes 32 are fixedly connected to the second waist-shaped groove 22 by bolts. In actual use, self-tapping screws can be used to initially fix the adjusting hole 32 to the second waist-shaped groove 22. After accurate adjustment, bolts are used for complete fixation. The blind groove structure design ensures both the adjustment guidance accuracy and the final locking rigidity. Simultaneously, the phased operation process allows construction personnel to effectively absorb construction errors and adapt to the installation requirements of complex steel structures 5. The bottom of the adjusting component 3 is provided with... The fixing plate 33 is fixedly connected to the panel material 4. The fixing plate 33 and the adjusting component 3 are integrally processed. In this embodiment, the two are integrally combined by forging and injection molding. This structure realizes the horizontal linear displacement adjustment of the panel material 4 through the through first waist-shaped groove 21, eliminating the accumulation of on-site errors, ensuring construction accuracy, and improving construction efficiency. Through the non-through second waist-shaped groove 22, combined with the radially arranged circular holes around the center point on the panel connecting ear plate, the adjustment realizes 360° omnidirectional angle adaptation, meets the spatial bearing requirements of complex steel structure 5, and solves the problems of the inability to adjust the horizontal depth, the cumbersome operation of spatial angle adjustment, the large amount of work, the inability to effectively absorb and eliminate construction deviations, and the high construction cost in the existing construction.

[0033] Please see Figure 3 The design of the fixed hole 31 having a larger diameter than the adjustment hole 32 forms a stepped fit structure, which not only ensures the quick centering and installation of the main positioning bolt, but also provides an adjustment margin through the width difference between the small diameter adjustment hole 32 and the second waist-shaped groove 22, realizing the fine-tuning positioning function during installation, while avoiding movement interference between bolt groups.

[0034] Please see Figure 4 The fixing plate 33 and the adjusting component 3 are an integral structure, which can be formed by welding or injection molding. The fixing plate 33 and the adjusting component 3 are vertically distributed, which improves the overall bending stiffness. The orthogonal distribution makes the fixing plate 33 naturally form an installation reference surface, which not only ensures the verticality of the panel material 4, but also simplifies the leveling process during on-site construction.

[0035] Please see Figure 1 and Figure 5 The end face of the connector 2 away from the clamp 1 is a curved surface, and the end face of the adjusting part 3 near the connector 2 is also a curved surface. The curved guide surface automatically corrects the angle deviation during assembly and realizes the self-centering function. The curved surface contact increases the force-bearing area and effectively disperses the local stress of the connection part. It is particularly suitable for the dynamic bearing requirements under wind load. Moreover, the curved surface occupies a small area and can avoid collisions between parts.

[0036] In summary, this adaptive adjustment connection structure for complex steel structures achieves horizontal linear displacement adjustment of the panel material 4 through the through-type first waist-shaped groove 21, eliminating the accumulation of on-site errors and ensuring construction accuracy. Simultaneously, the non-through-type second waist-shaped groove 22, in conjunction with the radially arranged circular holes on the panel connecting ear plate, achieves 360° omnidirectional angle adaptation, meeting the spatial load-bearing requirements of the complex steel structure 5, effectively solving problems such as difficult adjustment and large workload in traditional construction. This structure designs the second waist-shaped groove 22 as a blind groove structure, avoiding the cross-sectional weakening caused by through-grooves, ensuring resistance to shear forces and preventing groove deformation during bolt tightening, and ensuring adjustment accuracy and locking rigidity through the limiting effect at the bottom of the blind groove. Furthermore, the standardized prefabrication design of the clamp 1, connector 2, and adjustment component 3 allows for on-site installation with only bolt assembly, avoiding traditional welding processes, significantly simplifying the construction process, and improving installation efficiency. It is particularly suitable for the rapid construction needs of special building forms such as curved curtain walls and irregularly shaped roofs.
