Abstract
Description
Technical Field
[0001] This utility model relates to the field of C-shaped steel technology, and in particular to a C-shaped steel connector. Background Technology
[0002] C-shaped steel, a common steel profile, possesses a unique cross-sectional shape and excellent performance. With its good bending strength and load-bearing capacity, it is widely used in various fields such as building structures, bridge engineering, and machinery manufacturing. The C-shaped cross-section of C-shaped steel not only gives it high rigidity but also facilitates connection and combination with other components, meeting the needs of various complex structures. It is typically made of high-quality carbon structural steel or low-alloy high-strength steel, processed through hot rolling or cold rolling processes, ensuring the mechanical properties and dimensional accuracy of the C-shaped steel.
[0003] There are various ways to connect C-shaped steel sections. Depending on the specific application and requirements, different methods such as welding, bolting, and pinning can be selected. Welding is a permanent connection method. Using welding techniques such as arc welding and gas shielded welding, the joints of the C-shaped steel sections are melted and fused together to form a strong joint. This connection method has advantages such as high strength, high rigidity, and good sealing performance, making it suitable for structures subjected to heavy loads and vibrations. Bolting, on the other hand, is a detachable connection method. Bolts and nuts are used to fasten the C-shaped steel sections together, facilitating installation and disassembly, and is suitable for applications requiring frequent adjustments and replacements. Pinning is a simple and quick connection method. The ends of the C-shaped steel sections are inserted into connectors for rapid connection, suitable for temporary structures and applications requiring rapid installation. These connection methods each have their own characteristics, meeting the connection needs of C-shaped steel sections in different application scenarios.
[0004] Patent document CN202248291U discloses a C-shaped steel connector, which includes a connector body. The connector body is a U-shaped steel that can be nested inside a C-shaped steel. The bottom of the U-shaped steel has at least two threaded through holes. Two C-shaped steels are nested at both ends of the U-shaped steel. Fastening bolts are inserted into the threaded through holes. By tightening the fastening bolts, the U-shaped steel and C-shaped steels are locked together, thereby achieving the purpose of connecting the C-shaped steels. This utility model has a simple structure, low cost, reliable connection, easy installation and disassembly, strong compatibility, and can be widely promoted and used.
[0005] In the prior art of the aforementioned patent, a U-shaped steel is set inside the two C-shaped steels to hold the C-shaped steels in place. However, the dimensions and opening sizes of C-shaped steels of different specifications vary, and a U-shaped steel of a single size cannot be used to fit all sizes of C-shaped steels. If the inner dimension of the C-shaped steel is large, the U-shaped steel cannot properly abut against the inner wall of the C-shaped steel, thus failing to achieve a stable connection. Utility Model Content
[0006] The purpose of this utility model is to provide a C-shaped steel connector to overcome the above-mentioned shortcomings in the prior art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figure 1-6 A C-shaped steel connector includes a connecting block 3. Grooves 8 are formed on both sides of the connecting block 3. Multiple springs 10 are installed inside the grooves 8. Clamping blocks 11 are provided on both sides of the connecting block 3. Two clamping blocks 11 are slidably connected to the grooves 8. The clamping blocks 11 are elastically connected to the connecting block 3 via the springs 10. A fixing component is provided on the connecting block 3. First, two C-shaped steel bodies 1 are joined together. Then, two connecting blocks 3 are placed inside the C-shaped steel. Under the action of the springs 10, the clamping blocks 11 on both sides of the connecting block 3 can press against the inner wall of the C-shaped steel, thus enabling the two clamping blocks 11 to press against the inner wall of the C-shaped steel body 1. Then, the fixing component connects the connecting blocks 3 to the C-shaped steel body 1 respectively, thereby achieving the connection between the two C-shaped steel bodies 1.
[0026] As a preferred technical solution of this embodiment, the sidewalls of the two snap-fit blocks 11 away from the connecting block 3 are provided with inclined surfaces 12, and the upper part of the inclined surfaces 12 is provided with a vertical surface 13. The inclined surfaces 12 are provided to facilitate the smooth relative sliding between the connecting block 3 and the opening edge of the C-shaped steel body 1 during the downward snap-fit process, so as to push the snap-fit blocks 11 into the groove 8. The vertical surface 13 is provided to increase the contact area between the snap-fit blocks 11 and the inner wall of the C-shaped steel body 1, so that the connection between the snap-fit blocks 11 and the C-shaped steel body 1 is more stable.
[0027] As a preferred technical solution of this embodiment, the fixing component includes a through groove 5 at the bottom of the connecting block 3, and two threaded holes 9 at the top of the connecting block 3. Bolts 4 are installed in the internal threads of the two threaded holes 9, and nuts 6 are installed at one end of the bolts 4. The bolts 4 are connected to the two threaded holes 9 of the connecting block 3, and the two bolts 4 pass through the two mounting holes 2 opened on the C-shaped steel body 1. Then, by tightening the nuts 6, the connecting block 3 is fixed between the two C-shaped steel bodies 1.
[0028] As a preferred technical solution in this embodiment, a washer 7 is provided above the nut 6; the washer 7 can increase the stability of the nut 6 and prevent the nut 6 from falling off due to the inevitable vibration of the object during long-term use.
[0029] As a preferred technical solution in this embodiment, a rubber pad 15 is provided at the bottom of the connecting block 3. The rubber pad 15 is relatively soft, which can increase the protection of the contact surface of the C-shaped steel body 1 and reduce the wear of the C-shaped steel body 1. On the other hand, it can prevent relative sliding between the connecting block 3 and the C-shaped steel body 1.
[0030] As a preferred technical solution of this embodiment, a plurality of anti-slip grooves 14 are provided on the vertical surface 13, and a silicone filling layer 16 is provided inside the plurality of anti-slip grooves 14. By providing a silicone filling layer 16 inside the anti-slip grooves 14, the friction between the vertical surface 13 of the snap-fit block 11 and the side wall of the C-shaped steel body 1 can be increased, preventing the connecting block 3 from sliding relative to the C-shaped steel body 1, and increasing the stability of the connecting block 3.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
