Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a reinforced steel frame node connection and fixing device. Background Technology

[0002] Reinforced steel is steel whose performance is improved by various strengthening methods based on ordinary steel. For reinforced steel frame node connection, it refers to the use of special connection methods and construction measures in steel frame structure to enhance the connection performance at the node, so as to ensure the safety and reliability of the structure when bearing load.

[0003] Traditional connection methods often employ simple welding or ordinary bolts. Welded joints are prone to cracking due to stress concentration, reducing connection strength. Under heavy loads or vibrations, the weld may crack. Furthermore, when ordinary bolted connections are subjected to external impacts, some bolts are prone to loosening or even falling off, failing to guarantee long-term stable load-bearing capacity of the joint and affecting the safety of the entire structure. Utility Model Content

[0004] To address the issues of poor connection strength and easy loosening of some bolts, the purpose of this utility model is to provide a reinforced steel frame node connection and fixing device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a reinforced steel frame node connection and fixing device, including I-shaped steel and Z-shaped steel, wherein a connecting device is fixedly connected between the I-shaped steel and the Z-shaped steel, the connecting device including multiple fixing plates, the outer surfaces of the multiple fixing plates are symmetrically provided with first connecting grooves and second connecting grooves, the two first connecting grooves and second connecting grooves located on the same vertical horizontal line are jointly fixedly inserted with fixing bolts and anti-loosening bolt assemblies, a side support plate is fixedly installed on the upper surface of one of the fixing plates, one side of the side support plate is fixedly connected to the Z-shaped steel, one side of the other fixing plate is fixedly connected to the Z-shaped steel, and a fixing clamping plate is movably sleeved on the outer surface of the fixing bolt.

[0006] Preferably, the anti-loosening bolt assembly includes a screw, the outer surface of which is threaded with an adjusting nut and fitted with a pressure spring, and the two ends of the pressure spring are respectively fixedly connected with a pressure washer and a sliding disc.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention utilizes a combination of a connecting device and an anti-loosening bolt assembly. Four crisscrossing fixing plates, along with fixing bolts and the anti-loosening bolt assembly, construct a robust connection system. This structure effectively distributes and bears loads, ensuring a firm connection between the I-beams and Z-beams. It can withstand large external forces and complex stress conditions, guaranteeing the reliable load-bearing capacity of the steel frame joints in construction and other engineering projects. Within the anti-loosening bolt assembly, a pressure spring, a sliding disc, and a pressure washer work together. By adjusting the nut to compress the pressure spring, continuous pressure is applied to the connection, preventing bolt loosening even under vibration and dynamic load conditions, thus ensuring long-term connection stability.

[0015] 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.

[0016] Example:Figures 1-4 As shown, this utility model provides a reinforced steel frame node connection and fixing device, including I-shaped steel 11 and Z-shaped steel 12. The outer surfaces of both I-shaped steel 11 and Z-shaped steel 12 are sandblasted to increase the surface roughness of the steel, improve the adhesion between the subsequent connecting parts and the steel surface, make the connection more reliable, and help improve the durability and stability of the connection. Connecting plates 14 are symmetrically fixedly installed on the outer surface of I-shaped steel 11, and diagonal braces 15 are fixedly connected to the outer surface of connecting plates 14. One end of the diagonal brace 15 is fixedly connected to the Z-shaped steel 12. Multiple diagonal braces 15 are provided on the outer surface of the Z-shaped steel 12. The connecting holes 16 used in section 5 are horizontally and evenly distributed for connecting components such as the diagonal brace 15. This design provides standardized and diversified connection position options for the installation of components such as the diagonal brace 15, making it convenient to adjust the support position according to different working conditions using diagonal braces 15 of different sizes. Utilizing the principle of triangular stability, it provides additional support structure for the steel frame nodes, enhances the stability of the overall frame under stress, and shares the stress at the nodes, thereby further improving the load-bearing capacity of the connection and fixing device. A connecting device 13 is fixedly connected between the I-shaped steel 11 and the Z-shaped steel 12.

[0017] The connecting device 13 includes multiple fixing plates 17, with four fixing plates 17 in total. Two fixing plates 17 are arranged in a crisscross pattern with the other two fixing plates 17. This arrangement optimizes the structure of the connecting device 13 through a specific layout, allowing for more effective transmission and distribution of forces between the fixing plates 17, thereby further enhancing the stability of the connection between the connecting device 13 and the I-shaped steel 11 and the Z-shaped steel 12. The outer surfaces of the multiple fixing plates 17 are symmetrically provided with first connecting grooves 19 and second connecting grooves 18. The two first connecting grooves 19 located on the same vertical horizontal line are... Both the second connecting groove 18 are fixedly inserted with fixing bolts 20 and anti-loosening bolt assemblies 21. A side support plate 22 is fixedly installed on the upper surface of one of the fixing plates 17. One side of the side support plate 22 is fixedly connected to the Z-shaped steel 12. Multiple high-strength bolts are fixedly installed on one side of the side support plate 22. Multiple circular grooves that cooperate with the high-strength bolts are opened on the outer surface of the Z-shaped steel 12. The function is to ensure that a high-strength and reliable connection is formed between the side support plate 22 and the Z-shaped steel 12, and to ensure that the side support plate 22 can effectively play its role in strengthening the connection between the connecting device 13 and the Z-shaped steel 12.

[0018] Another fixing plate 17 is fixedly welded to one side of the Z-shaped steel 12. The outer surface of the fixing bolt 20 is movably fitted with a fixing plate 23. The fixing plate 23 is located below the four fixing plates 17. The fixing plate 23 is U-shaped, and one side of the fixing plate 23 abuts against the outer surface of the I-shaped steel 11. The operator can tighten the fixing plate 23 by rotating the nut in the fixing bolt 20. Through the special shape and position setting of the fixing plate 23, the fixing of the I-shaped steel 11 is further strengthened. The auxiliary connecting device 13 better connects the I-shaped steel 11 and the Z-shaped steel 12 into one, enhancing the tightness and stability of the connection.

[0019] The anti-loosening bolt assembly 21 includes a screw 24. An adjusting nut 25 is threaded onto the outer surface of the screw 24, and a compression spring 27 is fitted onto it. A pressure washer 28 and a sliding disc 26 are fixedly connected to both ends of the pressure spring 27, respectively. During installation, rotating the adjusting nut 25 moves it along the screw 24, thereby compressing the pressure spring 27. The compressed spring continuously generates elastic force, which is evenly transmitted to the surface of the connecting parts through the pressure washer 28, while the sliding disc 26 ensures the stability of the spring force direction.

[0020] Working principle: Arrange the four fixing plates 17 in a crisscross pattern, aligning the corresponding first connecting groove 19 and second connecting groove 18. Insert the fixing bolts 20 and anti-loosening bolt assemblies 21 into the corresponding connecting grooves. Initially tighten the adjusting nuts 25 to form a stable connection structure between the fixing plates 17, but do not tighten to the final torque. Connect the side support plate 22 to the corresponding circular groove on the Z-shaped steel 12 using high-strength bolts and tighten them. Initially connect the assembled connecting device 13 to the I-shaped steel 11 and Z-shaped steel 12. Position and rotate the nut in the fixing bolt 20 to make the fixing plate 23 abut against the outer surface of the I-shaped steel 11. Install the connecting plate 14 and the diagonal brace 15, fix the connecting plate 14 to the outer surface of the I-shaped steel 11, connect one end of the diagonal brace 15 to the connecting plate 14, and connect the other end to the connecting hole 16 on the Z-shaped steel 12 and tighten it. Use a torque wrench and other tools to tighten the fixing bolt 20 and the adjusting nut 25 in the anti-loosening bolt assembly 21 in sequence according to the torque value required by the design to ensure that the connection part reaches the specified tightness.

[0021] In the anti-loosening bolt assembly 21, the position of the pressure washer 28 is adjusted by rotating the adjusting nut 25 in conjunction with the screw 24, so that the pressure washer 28 is pressed against the fastener. The pressure spring 27 can keep the pressure washer 28 under high pressure and elastic force, thereby applying pressure to the connection part through the pressure washer 28 and the sliding plate 26, which plays the role of anti-loosening and fastening.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
