Description

Technical Field

[0001] This utility model belongs to the field of steel structure support technology and is mainly applied to engineering scenarios such as industrial equipment installation, temporary building support, exhibition and display erection, and machinery manufacturing assembly. It relates to a steel structure double-leg support frame. Through the optimized combination design of the base, columns, beams, and trapezoidal connectors, this support frame provides a stable and reliable support system for various equipment, structures, and temporary facilities, and is particularly suitable for working conditions involving frequent disassembly and assembly or bearing large loads. Background Technology

[0002] Double-leg support frames are widely used as basic load-bearing structures in fields such as industrial equipment installation, building support, and exhibition displays. However, traditional support frames generally suffer from insufficient structural stability. Existing support frames often employ simple welded structures of uprights and beams. Under dynamic loads or long-term vibration, stress concentration easily occurs at the welded areas, leading to weld cracking or structural deformation. Simultaneously, the base design of traditional support frames is overly simplistic, lacking effective anti-slip measures, making them prone to slippage on smooth surfaces or under inclined conditions, posing serious safety hazards. Furthermore, asymmetrical support structure designs can easily lead to uneven load distribution, causing the support frame to be unbalanced or even overturn. These problems severely restrict the reliability of support frames under heavy-load conditions, necessitating structural optimization to improve overall stability.

[0003] Traditional support frames have significant shortcomings in height adjustment and functional expansion. Most support frames use a one-piece column design, which cannot flexibly adjust the height according to usage needs, or requires complex disassembly and reassembly to achieve height adjustment, greatly reducing ease of use. In terms of connection methods, traditional support frames mostly rely on welding for fixation, which is not only complex to install, but also makes it difficult to adjust the structural layout according to actual needs. Furthermore, the upper connection structure of the support frame is simple and lacks standardized interfaces, making it unable to adapt to the supported objects of different sizes, severely limiting its application range. These functional limitations often require users to purchase multiple specialized support frames for different working conditions, increasing operating costs and reducing work efficiency.

[0004] Traditional support frames are structurally inadequate to effectively resist lateral loads and torques, especially when supporting equipment with a high center of gravity, making them prone to tipping over due to external forces. Furthermore, the connection points of the various components of the support frame are prone to loosening over long-term use, requiring frequent maintenance. These shortcomings not only increase the risks and maintenance costs of use but also limit the application range of support frames in complex working conditions. Summary of the Invention

[0005] The purpose of this utility model is to provide a steel structure double-leg support frame to solve the problems of insufficient stability, limited adjustment function and poor safety of the support frame in the prior art.

[0006] To address the aforementioned problems, this utility model provides a steel structure double-leg support frame, comprising: The base is used to support the entire support frame; The pillars consist of two columns mounted on the base. A crossbeam, connecting the two columns laterally; Two trapezoidal connectors are attached to the top of the crossbeam.

[0007] Furthermore, the trapezoidal connector is provided with mounting holes for connecting other structures.

[0008] Furthermore, the column and the base are fixed together by bolts.

[0009] Furthermore, both ends of the crossbeam are fixedly connected to two trapezoidal connectors by bolts.

[0010] Furthermore, the part of the base that contacts the ground is equipped with an anti-slip structure.

[0011] Furthermore, the columns are upright column structures, with two columns arranged parallel to each other.

[0012] Furthermore, mounting holes are provided on the crossbeam.

[0013] Furthermore, the upper and lower bases of the trapezoidal connector are arranged in parallel, and the sides are straight.

[0014] Furthermore, the base has a chamfered edge.

[0015] Furthermore, the bottom surface of the base is a flat plate structure arranged symmetrically on both sides.

[0016] This utility model has the following beneficial effects: (1) This utility model constructs a highly stable support system through a modular combination design of the base, columns, beams, and trapezoidal connectors. Two parallel columns are connected to the base by high-strength bolts to form a stable vertical support system, effectively avoiding the eccentric load problem that is prone to occur in traditional support frames. The beams are made of I-beam steel, which not only enhances the lateral connection strength, but also provides convenience for functional expansion through their mounting hole design. The mounting hole layout of the trapezoidal connectors further improves the connection adaptability of the upper structure. The base adopts an edge chamfering design and a bottom anti-slip structure, which significantly improves the overall stability of the support frame. This overall structural design enables the support frame to remain stable and reliable under various working conditions, and is particularly suitable for industrial application scenarios that need to withstand large loads.

[0017] (2) The innovative structural design of this utility model achieves excellent mechanical performance. The column adopts a modular segmented design, and the height can be adjusted through a precisely arranged array of mounting holes, which not only ensures the structural strength but also provides a convenient height adjustment function. The rigid connection between the beam and the column forms a stable structure that can effectively resist the combined action of vertical load, horizontal load and torque load. The parallel design of the upper and lower bases of the trapezoidal connector ensures the flatness of the connection surface, while the straight side design improves the component's resistance to instability. The bolt connection between each component adopts an anti-loosening design to ensure that reliable connection performance can still be maintained under long-term vibration environment. This comprehensive force system design enables the support frame to have excellent load-bearing capacity and stability while maintaining structural simplicity.

[0018] (3) This utility model has outstanding advantages in terms of safety and ease of use. The chamfering of the base eliminates the safety hazards caused by sharp edges, and the anti-slip structure design effectively prevents the risk of slippage of the support frame on smooth ground. The standardized mounting hole design lowers the threshold of use, making installation and adjustment easy. The modular structure simplifies transportation and storage, and the segmented column design facilitates flexible combination according to actual needs. The multiple mounting point selection on the trapezoidal connectors provides greater installation flexibility, and the standardized mounting hole design on the crossbeam greatly expands the scope of functional applications, improves the user experience of the product, and enables the support frame to meet the different needs of multiple fields such as industry, construction, and exhibition, with broad application prospects and practical value.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0024] like Figures 1 to 4 In the embodiment of the steel structure double-leg support frame of this utility model shown, the support frame adopts a modular design concept. Through the optimized combination of four core components—base 1, column 2, crossbeam 4, and trapezoidal connector 3—a support system with high stability, scalability, and safety is constructed. The components, through precise cooperation, form a complete force-bearing system capable of adapting to the support needs of various application scenarios.

[0025] In one embodiment, the base 1 serves as the basic support platform for the entire support structure. The bottom surface is treated to form an anti-slip structure, which overcomes the defect of traditional support frames being prone to slipping on smooth ground by increasing the friction coefficient of the contact surface.

[0026] In one embodiment, the bottom surface of the base 1 is made of patterned steel plate, preferably with diamond or bean-shaped raised patterns, and is integrally formed by stamping. This structure features high wear resistance and long service life, making it suitable for heavy-duty applications.

[0027] In one embodiment, the base has a chamfered edge. The chamfering of the base 1 edge eliminates the safety hazards caused by sharp edges and also improves the overall aesthetics through the streamlined design.

[0028] In one embodiment, the two columns 2 are made of high-strength steel. The parallel arrangement of the columns 2 makes the stress distribution more uniform and avoids the eccentric load problem that is easy to occur in traditional asymmetrical support structures.

[0029] In one embodiment, the column 2 and the base 1 are connected by high-strength bolts, which has the advantages of convenient installation, simple maintenance and repeated disassembly.

[0030] In one embodiment, column 2 adopts a modular segmented design, with each segment equipped with standardized mounting holes, and height adjustment achieved through high-strength bolt connections. This design, through a precisely arranged array of mounting holes, allows for stepless height adjustment within a certain range, meeting the needs of different application scenarios. The segmented structure facilitates transportation and storage, and can be flexibly combined according to actual needs during installation. This column design ensures both structural strength and provides convenient height adjustment functionality, making it suitable for industrial applications requiring frequent adjustments to support height.

[0031] In one embodiment, the crossbeam 4 is an I-beam steel, which has excellent bending and torsional resistance. The connection between the crossbeam 4 and the column 2 adopts a rigid connection method. The mounting holes 5 evenly distributed on the crossbeam 4 adopt a standardized size design, which can be compatible with various specifications of connectors, greatly expanding the functional adaptability of the support frame.

[0032] In one embodiment, the two ends of the crossbeam 4 are fixedly connected to two trapezoidal connectors 3 by bolt connection. The bolt connection adopts an anti-loosening design to ensure that reliable connection performance can be maintained under long-term vibration environment.

[0033] In one embodiment, the upper and lower bases of the trapezoidal connector 3 are parallel, and the sides are straight. The parallel design of the upper and lower bases of the two trapezoidal connectors 3 ensures the flatness of the connection surface, facilitating precise docking with other structures. The straight side design not only simplifies the manufacturing process but also improves the component's resistance to instability.

[0034] In one embodiment, the trapezoidal connector 3 is provided with mounting holes 5 for connecting other structures. The mounting holes 5 on the trapezoidal connector 3 are arranged in an array, providing multiple connection point options, and the installation position can be flexibly selected according to actual needs.

[0035] This utility model's steel structure double-leg support frame, through innovative structural design and precise component assembly, successfully overcomes the shortcomings of traditional support frames in terms of stability, safety, and functionality. Its modular design not only improves product performance but also significantly expands its application range, enabling it to meet the support needs of various fields such as industry, construction, and exhibitions. This design ensures structural strength while also considering ease of use and aesthetics, demonstrating significant technological advancement and practical value.

[0036] This support frame achieves optimal stress distribution through a rational structural layout. Vertical loads are directly transferred to the base 1 via the columns 2; horizontal loads are shared by the beams 4 and trapezoidal connectors 3; and torsional loads are resisted through the coordinated action of the entire frame structure. This comprehensive stress distribution system ensures the support frame remains stable and reliable under various complex working conditions. The chamfered edges of the base 1 prevent the risk of injury to personnel; the standardized mounting holes lower the barrier to entry; and the modular structure simplifies transportation and storage.

[0037] The innovation of this utility model lies in the synergistic effect of four core components to construct a stable support structure. The base 1 provides stable foundation support, and its anti-slip structure and chamfered design solve the stability and safety problems of traditional support frames. The parallel arrangement of the columns 2 ensures vertical load-bearing capacity. The crossbeam 4 not only serves a connecting function, but its I-beam steel design also endows the support frame with lateral stability and functional expandability. The special geometry and arrayed mounting hole layout of the trapezoidal connector 3 greatly enhance the upper connection capacity and adaptability of the support frame.

[0038] The structural design of this support frame fully considers various working conditions in practical applications. The anti-slip design of the base 1 allows it to adapt to different ground materials; the parallel arrangement of the columns 2 ensures the even distribution of load; the mounting holes of the crossbeam 4 facilitate functional expansion; and the multi-point connection scheme of the trapezoidal connector 3 provides greater installation flexibility, enabling the support frame to maintain structural simplicity while possessing excellent performance and wide applicability.
