Description

Technical Field

[0001] This utility model relates to the field of C-shaped steel technology, specifically to a C-shaped steel for seismic bracing. Background Technology

[0002] Installing seismic bracing on the exterior of pipes inside a building can effectively reduce earthquake damage to the pipes. One example, a C-shaped steel structure (CN220433901U), includes a main steel body with side steel bodies integrally formed. The main steel body and side steel bodies have multiple sets of anti-slip grooves on both sides of its outer wall. The inner wall of the main steel body has multiple sets of integrally formed main steel body reinforcing ribs equidistantly arranged from left to right. The inner wall of the side steel bodies has multiple sets of integrally formed side steel body reinforcing ribs equidistantly arranged from top to bottom. A large groove is formed between adjacent main steel body reinforcing ribs, and the interior of the large groove is filled with a large anti-slip strip.

[0003] However, existing C-shaped steel is unable to effectively dissipate seismic energy through its own structure when faced with the complex stress generated by an earthquake, and is prone to plastic deformation and fracture. At the same time, C-shaped steel is usually fixed to other supports by welding, which makes it inconvenient for later disassembly and installation. Utility Model Content

[0004] In view of the problems existing in the current C-shaped steel, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a C-shaped steel for seismic bracing, which solves the problem that some C-shaped steels are difficult to effectively dissipate seismic energy through their own structure when facing the complex stress generated by earthquakes, and are prone to plastic deformation and fracture. At the same time, C-shaped steels are usually fixed to other supports by welding, which makes it inconvenient for later disassembly and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A C-shaped steel for seismic bracing includes a web, two flanges, and two connecting rods. The two flanges are respectively disposed on both sides of the web. Reinforcing ribs are fixedly connected between the two flanges and the upper surface of the web. Multiple fixing blocks are fixedly connected to the inner walls of the two webs. A fixing mechanism is provided between each connecting rod and the corresponding two fixing blocks. The two connecting rods are fixed by their respective fixing mechanisms. A support mechanism is provided between the two connecting rods.

[0008] Preferably, the fixing mechanism includes multiple bolts, and two slots are symmetrically opened at both ends of the two connecting rods. Each slot matches a corresponding fixing block. Each fixing block has a placement groove on one side, and each placement groove has an internal threaded hole. Each bolt is respectively set inside the corresponding internal threaded hole.

[0009] Preferably, the support mechanism includes a support rod and two T-shaped blocks. One side of each of the two connecting rods is provided with a T-shaped groove. The two T-shaped blocks are respectively inserted into the interior of the corresponding T-shaped grooves. The support rod is fixedly connected between the two T-shaped blocks.

[0010] Preferably, a through hole is provided between the two corresponding slots, and each through hole is matched with a corresponding bolt.

[0011] Preferably, one side of the flange has multiple mounting holes, each of which matches a corresponding placement slot.

[0012] Preferably, the cross-section of each of the reinforcing ribs is trapezoidal.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model effectively enhances the bending and torsional resistance of C-shaped steel by using reinforcing ribs, making it less prone to deformation under seismic forces. When subjected to horizontal seismic forces, the reinforcing ribs can evenly distribute the force to various parts of the C-shaped steel, avoiding deformation and damage caused by local stress concentration.

[0015] 2. In this utility model, by fitting one end of the connecting rod onto the upper surface of the corresponding two fixing blocks, the tensile strength between the upper and lower parts can be improved, making the seismic support more stable. Then, the connecting rod can be fixed with each bolt, which facilitates the installation and disassembly of the connecting rod.

[0016] 3. In this utility model, by inserting two T-shaped blocks into the corresponding T-shaped grooves, the support rod can be easily installed, and the support rod can then be used to improve the tensile strength between the two connecting rods. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a C-shaped steel for seismic bracing.

[0025] This utility model provides, for example Figure 1-3 The C-shaped steel for seismic bracing shown includes a web 1, two flanges 2, and two connecting rods 3. The two flanges 2 are respectively disposed on both sides of the web 1. Reinforcing ribs 4 are fixedly connected between the two flanges 2 and the upper surface of the web 1. Multiple fixing blocks 5 are fixedly connected to the inner walls of the two webs 1. A fixing mechanism is provided between each connecting rod 3 and the corresponding two fixing blocks 5. The two connecting rods 3 are fixed by their respective fixing mechanisms. A support mechanism is provided between the two connecting rods 3.

[0026] The stiffener 4 can effectively enhance the bending and torsional resistance of C-shaped steel, making it less prone to deformation under seismic forces. When subjected to horizontal seismic forces, the stiffener can evenly distribute the force to various parts of the C-shaped steel, avoiding deformation and damage caused by local stress concentration.

[0027] To facilitate the installation of connecting rod 3, such as Figure 3 As shown, the fixing mechanism includes multiple bolts 6. Two slots are symmetrically opened at both ends of the two connecting rods 3. Each slot matches a corresponding fixing block 5. A placement groove is opened on one side of each fixing block 5. An internal threaded hole is opened inside each placement groove. Each bolt 6 is set inside the corresponding internal threaded hole. A through hole is opened between the two corresponding slots. Each through hole matches a corresponding bolt 6. Multiple mounting holes are opened on one side of the flange 2. Each mounting hole matches a corresponding placement groove.

[0028] One end of the connecting rod 3 is respectively fitted onto the upper surface of the two corresponding fixing blocks 5, thereby improving the tensile strength between the upper and lower parts and making the seismic support more stable. Then, the connecting rod 3 can be fixed with each bolt 6, which facilitates the installation and disassembly of the connecting rod 3.

[0029] To secure the connecting rod 7, such as Figure 1-3 As shown, the support mechanism includes a support rod 7 and two T-shaped blocks 8. T-shaped grooves are provided on one side of each of the two connecting rods 3. The two T-shaped blocks 8 are respectively inserted into the interior of the corresponding T-shaped grooves. The support rod 7 is fixedly connected between the two T-shaped blocks 8.

[0030] Insert the two T-shaped blocks 8 into the corresponding T-shaped slots, which will facilitate the installation of the support rod 7. The support rod 7 can then be used to improve the tensile strength between the two connecting rods.

[0031] To improve the performance of reinforcing ribs, such as Figure 1-2 As shown, the cross-section of each of the reinforcing ribs 4 is trapezoidal.

[0032] The trapezoidal shape of the reinforcing ribs gives them natural stability. Compared to other shapes, the base of the trapezoidal structure is wider, forming a stable support surface that can better resist tilting or deformation caused by external forces.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
