Abstract
Description
Technical Field
[0001] This utility model relates to the field of rigid structures, and in particular to a steel truss structure. Background Technology
[0002] In modern architecture and large-scale engineering structures, steel trusses are widely used in various buildings and engineering facilities, such as stadiums, exhibition halls, and bridges, due to their advantages such as good load-bearing capacity, high space utilization, and ease of installation.
[0003] In the construction of steel trusses, the connection between steel columns and steel beams is a crucial structural element. When a steel column needs to connect two sets of steel beams simultaneously, existing technologies face numerous challenges. Traditional connection methods, such as simple welding or bolting, struggle to ensure the stability of the connection node under large loads or complex stresses. Loads transmitted in different directions by the two sets of steel beams can easily cause eccentric stress on the steel column at the connection point, leading to structural deformation or even failure.
[0004] On the one hand, while welded connections offer a degree of integrity, thermal stress during welding can easily alter the local properties of the steel, and weld quality is difficult to guarantee completely. Once welding defects occur, the stability of the connection will be significantly compromised under long-term use and complex stress conditions. On the other hand, while bolted connections facilitate installation and disassembly, they are prone to loosening under complex loads from two sets of steel beams. This prevents them from effectively restraining the relative displacement between the steel beams and columns, thus affecting the overall stability of the steel truss structure. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by using a connection method where a stabilizing screw passes through the steel column and the stabilizing end plate, corresponding to the first and second preset screw holes. This effectively avoids eccentric stress when facing complex and variable loads, providing stability to the connection node and greatly reducing the risk of structural deformation or damage due to unstable connections. This provides a solid guarantee for the safe operation of the entire steel truss structure.
[0006] To solve the above-mentioned technical problems, the present invention can effectively improve the stability of steel columns when connecting two sets of steel beams simultaneously through the following technical solution.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A steel truss structure, comprising:
[0009] A steel column, wherein two rows of pre-set screw holes are evenly provided in the middle region of the steel column;
[0010] One rigid beam is horizontally installed on one side of the steel column;
[0011] Rigid beam two is set on the other side of the steel column, parallel to rigid beam one;
[0012] The stabilizing end plate is connected to the contact ends of the first and second rigid beams and the steel column, respectively. The two rows of the stabilizing end plate are evenly provided with second preset screw holes in the middle area.
[0013] The stabilizing screw is threaded through the first and second preset screw holes to connect the steel column, rigid beam one, and rigid beam two to improve overall stability.
[0014] Preferably, the stabilizing end plate is fixed to the end face of the steel column connecting the first and second rigid beams by fastening bolts.
[0015] Preferably, the upper and lower end faces of the stabilizing end plate are connected to limit clamps, which are used to limit the displacement of rigid beam one or rigid beam two.
[0016] Preferably, the first and second preset screw holes are arranged in two vertical rows and their positions correspond one-to-one to ensure that the screw is evenly stressed.
[0017] Preferably, the inner wall of the steel column is provided with several reinforcing members on both sides. One side of the reinforcing member is attached to the inner wall of the steel column, and the other side is attached to the side of the limiting clamp to enhance the structural strength of the connection part.
[0018] Preferably, the reinforcing member is an L-shaped plate structure, and one side of the reinforcing member is connected to the inner wall of the steel column by bolts.
[0019] Preferably, triangular reinforcing ribs are welded between the two plates of the reinforcing member to improve its bending resistance.
[0020] Preferably, positioning plates are connected to both sides of the limiting clamp, and a guide groove is provided inside the reinforcing member. The positioning plates are inserted into the guide groove to enhance the stability of the limiting clamp.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] The steel truss provided in this application, through the connection method of the stabilizing bolts penetrating the steel columns and the corresponding first and second preset bolt holes of the stabilizing end plates, can effectively avoid the occurrence of eccentric force when facing complex and variable loads. While providing stability to the connection nodes, it greatly reduces the risk of deformation or damage to the structure due to unstable connections, and provides a solid guarantee for the safe operation of the entire steel truss.
[0023] During installation, the limiting clamp can quickly and accurately position the steel beam initially, facilitating the subsequent installation of the stabilizing bolts. Simultaneously, the guide groove of the reinforcing member and the positioning plate of the limiting clamp work closely together, acting as a precision guiding device to ensure that the steel beam finds the correct position accurately when docking with the steel column. This significantly improves construction efficiency, reduces human error during installation, and makes the entire steel truss structure erection more efficient and precise.
[0024] The unique L-shaped plate structure design of the reinforcing member in this application, combined with triangular reinforcing ribs welded between the plates, gives it excellent bending resistance. In practical use, it can effectively disperse the enormous stress at the joints, significantly enhance the structural strength of the connection points, and thus improve the load-bearing capacity of the entire steel truss. This allows the structure to handle the heavy-load conditions commonly found in large buildings and engineering facilities with ease, ensuring the safety and stability of the structure.
[0025] The first and second pre-set screw holes in this application are both designed with two vertical rows. This ingenious layout allows for vertical displacement adjustment within a certain range during installation, effectively improving the applicability of the installation and better adapting to different architectural designs and construction requirements. Furthermore, the reinforcing members are connected to the inner wall of the steel column via bolts, facilitating disassembly and repositioning according to the actual project conditions, further enhancing the flexibility of this steel truss structure in various scenarios.

[0045] The steel structure truss of this application is mainly composed of steel columns 1, rigid beam 1 2, rigid beam 2 3, stabilizing end plate 4, and stabilizing bolts 5. The following is a detailed description of its structure and working principle.
[0046] Detailed structure and connection method of each component
[0047] I. Detailed Structure and Connection Methods of Each Component
[0048] Steel column 1: The main body is made of steel, and two rows of pre-set screw holes 101 are evenly opened in the middle area. Several L-shaped plate-shaped reinforcing members 7 are provided on both sides of the inner wall. One side of the plate of the reinforcing member 7 is connected to the inner wall of the steel column 1 by bolts. Triangular reinforcing ribs are welded between the two sides of the plate, and guide grooves 701 are also opened inside.
[0049] Rigid Beam 1 (2) and Rigid Beam 2 (3): Both are made of steel, are horizontally arranged and parallel to each other, and are located on both sides of steel column 1 respectively.
[0050] Stabilizing end plate 4: Made of steel plate, it is connected to the contact ends of rigid beam 2 and rigid beam 3 with steel column 1. Two rows of pre-set screw holes 401 are evenly spaced in the middle area, corresponding to the positions of the first pre-set screw holes 101 on the steel column 1. Limiting clamps 402 are connected to the upper and lower end faces, and positioning plates 403 are connected to both sides of the limiting clamps 402. They are fixed to rigid beam 2 and rigid beam 3 by fastening bolts 6 at the four corners.
[0051] Stabilizing screw 5: The screw is designed to fit the internal threads of the first preset screw hole 101 and the second preset screw hole 401, and is used to pass through both to achieve the threaded connection of steel column 1, steel beam 1 2 and steel beam 2 3.
[0052] Connection process: First, fix the reinforcing member 7 to the inner wall of the steel column 1, and then use the fastening bolts 6 to install the stabilizing end plate 4 at the end of the steel beam. Next, bring the steel beam close to the steel column 1, align the bolt holes, insert the positioning plate 403 into the guide groove 701, and finally screw in the stabilizing bolt 5 to complete the connection.
[0053] II. Working Principle
[0054] When the steel truss structure is put into use, steel beams 1-2 and 2-3 will be the first to bear various loads from the building structure or external equipment. These loads are diverse, including vertical gravity loads, horizontal wind loads, and seismic loads caused by earthquakes. As the main force-transmitting components, the steel beams will quickly transfer these loads of different directions and natures to the connection points with the steel column 1.
[0055] The key function of the stabilizing bolt 5: The stabilizing bolt 5 passes through the first pre-set bolt hole 101 on the steel column 1 and the second pre-set bolt hole 401 on the stabilizing end plate 4, forming a tight threaded connection. When the load is transferred to the connection node, the stabilizing bolt 5 acts like a strong link, restricting the relative displacement between the steel column 1, rigid beam 2, and rigid beam 3. Since the first pre-set bolt hole 101 and the second pre-set bolt hole 401 are both arranged in two vertical rows and are corresponding in position, the stabilizing bolt 5 can evenly bear the force transmitted from all directions, avoiding excessive local stress. For example, when rigid beam 2 is subjected to a large horizontal load, the stabilizing bolt 5 will distribute this force to the steel column 1 and rigid beam 3, preventing the connection node from deforming or being damaged due to eccentric stress, and ensuring the stability of the entire structure under complex stress conditions.
[0056] The limiting function of the limiting clamp 402: The limiting clamp 402 on the upper and lower end faces of the stabilizing end plate 4 plays a precise limiting role in the structure. During the installation of steel beam 2 and steel beam 3, the limiting clamp 402 acts like baffles on both sides of the track, constraining the steel beams to connect with the stabilizing end plate 4 only in specific positions and directions, preventing misalignment or tilting of the steel beams during the connection process, and creating accurate conditions for the subsequent installation of fastening bolts 6 and stabilizing screws 5. During the use of the structure, the limiting clamp 402 continuously restricts the displacement of the steel beams in the direction perpendicular to the connection surface, ensuring that the connection between the steel beams and the steel column 1 always remains in the designed position, enhancing the reliability of the connection.
[0057] The strengthening function of reinforcing member 7: The reinforcing members 7 on both sides of the inner wall of the steel column 1 are L-shaped plate structures. One side is tightly attached to the inner wall of the steel column 1 by bolts, and the other side is attached to the side of the limiting clamp 402. When installing the steel beam, the guide groove 701 inside the reinforcing member 7 cooperates with the positioning plates 403 on both sides of the limiting clamp 402, like a mortise and tenon structure, guiding the steel beam to accurately align with the steel column 1, improving the convenience and accuracy of installation. When the structure is under load, the reinforcing member 7 can not only disperse the stress at the joint, but also improve the bending resistance through its own triangular reinforcing ribs. When the connection joint is subjected to a large bending moment, the triangular reinforcing ribs can effectively resist bending deformation, evenly distributing the force to the steel column 1 and the steel beam, further enhancing the structural strength and stability of the connection.
[0058] Through the coordinated action of the aforementioned components, the entire steel truss structure forms an organic whole. When a certain part is subjected to load, the force is rapidly transmitted to other parts through steel beams and connecting nodes. The components cooperate and share the load, ensuring the stable operation of the steel truss structure under various complex working conditions, effectively meeting the structural safety and reliability requirements of buildings and engineering projects. Even during long-term use, facing continuously changing loads and environmental factors, the connection structure of this steel truss structure can maintain good performance thanks to its rational design and the coordinated action of its components, reducing maintenance and repair costs caused by unstable connections.
[0059] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
