Description

Technical Field

[0001] This utility model relates to the field of building keel, and in particular to earthquake-resistant keel and its easy-fastening structure. Background Technology

[0002] In fields such as architectural decoration and structural reinforcement, the keel serves as a crucial supporting component, and its stability and seismic performance are of paramount importance. Especially in earthquake-prone areas, the seismic design of buildings is directly related to the safety of people's lives and property, making the seismic resistance of the keel a key element of building structural safety.

[0003] Currently, there are various types of keel structures on the market, but they generally have insufficient seismic performance. Traditional keels mostly use simple nailing, riveting, or ordinary bolt connections.

[0004] Existing technologies suffer from the following main drawbacks: Current keel structures lack effective shock absorption mechanisms and cannot effectively dissipate seismic energy. When an earthquake occurs, the keel directly bears the seismic force, making it prone to damage due to stress concentration, thus affecting the stability of the entire building structure. Therefore, developing an earthquake-resistant keel with good seismic performance, stable connections, and convenient installation, along with its easy-locking structure, is of significant practical importance. It can fill a market gap and meet the urgent demand of the construction industry for high-quality keel products. Utility Model Content

[0005] To address the technical problem of the lack of effective shock absorption and buffering mechanisms in existing keel systems, this utility model provides an earthquake-resistant keel system and its easy-fastening structure.

[0006] This utility model is achieved by the following technical solution: an earthquake-resistant keel, including a base, a support plate fixedly installed on the top of the base, and an anchoring structure provided at the bottom of the base to enhance the connection stability between the base and the ground and other installation foundations, and to prevent displacement during an earthquake.

[0007] A support edge is fixedly installed vertically above the support plate. Locking screw holes are opened on the surface of both the support edge and the fixed edge. The fixed edge overlaps the outside of the support edge. The edge of the plate of the fixed edge is vertically integrated to form a locking plate. The fixed edge and the locking plate form an L shape. A reinforcing rib for enhancing the structural strength is fixedly installed between the fixed edge and the locking plate.

[0008] A locking block is fixedly connected to the top of the support plate. An installation gap is formed between adjacent locking blocks. An arc-shaped shock absorber is installed between the installation gaps. A connecting piece fixing block is locked onto the surface of the arc-shaped shock absorber. A keel body is riveted to the top of the arc-shaped shock absorber.

[0009] The easy-lock structure includes a first fastening frame, and a second fastening frame is fixedly connected by a limiting edge. A threaded hole extends through both the first and second fastening frames, and a fastening bolt threaded through the threaded hole securely connects the first and second fastening frames. The easy-lock structure is used to securely connect the supporting edge and the fixed edge. The first and second fastening frames are U-shaped, and the U-shaped groove formed by the first and second fastening frames locks the supporting edge and the fixed edge.

[0010] The fastening bolts are threaded through the first fastening bracket, the second fastening bracket, and the locking bolt hole. The fastening bolts also have threads that penetrate the locking bolt hole, further enhancing the stability of the connection. Under external forces such as earthquakes, this ensures that the supporting and fixed sides will not loosen or separate, maintaining the integrity and stability of the keel structure.

[0011] As a further improvement to the above solution, an anchoring structure is installed at the bottom of the base, which is firmly connected to the ground or other installation foundation. In the event of an earthquake, this connection method effectively enhances the stability of the base, preventing displacement under seismic forces and providing a stable supporting foundation for the entire keel structure.

[0012] As a further improvement to the above solution, the reinforcing ribs are welded to the locking plate and the fixed edge to enhance the overall structural strength of the fixed edge supporting the keel body.

[0013] As a further improvement to the above solution, the supporting edge and fixed edge on the support plate work together through locking screw holes, locking plates, and reinforcing ribs. The reinforcing ribs are welded between the locking plates and the fixed edges, enhancing the overall structural strength of the locking plate supporting the keel body, enabling the support structure to withstand greater external forces.

[0014] As a further improvement to the above scheme, when an earthquake generates vibrations, the arc-shaped damping pads utilize their own arc-shaped structure to undergo elastic deformation, effectively dissipating and buffering earthquake energy, reducing the seismic force transmitted to the main body of the keel, and preventing the main body of the keel from being damaged due to stress concentration.

[0015] As a further improvement to the above solution, a threaded hole passes through both the first and second fastening brackets, and the thread of the fastening bolt passes through the threaded hole. During installation, tightening the fastening bolt causes the first and second fastening brackets to generate a pulling force that brings them closer together, thereby clamping the support side and the fixed side together to achieve a fast connection.

[0016] As a further improvement to the above solution, the first and second fastening frames in the easy-lock structure are fixedly connected by a limiting edge to form an integral fastening structure. The first and second fastening frames are U-shaped, and their slots tightly lock the supporting edge and the fixed edge, realizing the initial positioning and clamping of the connection part.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model incorporates arc-shaped damping pads. During an earthquake, these pads, due to their unique arc-shaped structure, undergo elastic deformation within the installation gap. This deformation effectively dissipates and buffers the energy generated by the earthquake, significantly reducing the seismic force transmitted to the main keel structure, thus preventing damage to the keel structure due to stress concentration. Compared to traditional keels lacking a damping mechanism, this utility model effectively improves the stability of the keel during earthquakes, greatly reducing the risk of structural damage due to keel failure, and providing more reliable earthquake resistance for buildings.

[0019] 2. In terms of connection, the easy-locking structure plays an important role in this utility model. The first fastening frame and the second fastening frame are fixedly connected by the limiting edge and form a U-shape. The groove tightly locks the supporting edge and the fixed edge, realizing the initial positioning and stable clamping of the connection part.

[0020] 3. During installation, tightening the fastening bolts creates a strong pulling force between the first and second fastening frames, firmly clamping the supporting and fixed sides. This multi-fastening design, compared to traditional simple nailing, riveting, or ordinary bolt connections, greatly enhances the stability of the connection, ensuring that the supporting and fixed sides will not easily loosen or separate under strong external forces such as earthquakes. This maintains the integrity and stability of the keel structure and guarantees the safety of the building structure.

[0021] 4. This utility model significantly enhances the overall structural strength of the fixed-side support keel by incorporating reinforcing ribs between the fixed edge and the locking plate, and employing a welded connection. The reinforcing ribs effectively disperse and bear external forces, enabling the support structure to withstand greater loads. Even in extreme conditions such as earthquakes, the keel's reliable support for the building structure is guaranteed. Attached Figure Description

[0034] Specifically, the anchoring structure at the bottom of base 1 is firmly connected to the ground or other installation foundation. During an earthquake, this connection effectively enhances the stability of base 1, preventing displacement and providing a stable support foundation for the entire keel structure.

[0035] A support edge 21 is fixedly installed vertically above the support plate 2. Locking screw holes 22 are opened on the surface of both the support edge 21 and the fixed edge 23. The outer side of the support edge 21 overlaps with the fixed edge 23. The edge of the plate of the fixed edge 23 is vertically integrated to form a locking plate 24. The fixed edge 23 and the locking plate 24 form an L-shape. A reinforcing rib 25 for enhancing the structural strength is fixedly installed between the fixed edge 23 and the locking plate 24.

[0036] A further technical solution involves welding the reinforcing rib 25 to the locking plate 24 and the fixed edge 23 to enhance the overall structural strength of the fixed edge 23 supporting the keel body 7.

[0037] In a further specific technical solution, the supporting edge 21 and the fixed edge 23 on the supporting plate 2 work together through the locking screw hole 22, the locking plate 24, and the reinforcing rib 25. The reinforcing rib 25 is welded between the locking plate 24 and the fixed edge 23, which enhances the overall structural strength of the locking plate 24 supporting the keel body 7, enabling the supporting structure to withstand greater external forces.

[0041] Combination Figures 6-7 The difference between this embodiment and embodiment 1 is that this embodiment further proposes an earthquake-resistant keel easy-fastening structure. The easy-fastening structure 8 includes a first fastening frame 81, the first fastening frame 81 and the second fastening frame 82 are fixedly connected by a limiting edge 83, a threaded hole 84 is opened to pass through the first fastening frame 81 and the second fastening frame 82, and a fastening bolt 85 is threaded through the threaded hole 84 to fasten the first fastening frame 81 and the second fastening frame 82. The easy-fastening structure 8 is used to fasten the support edge 21 and the fixed edge 23.

[0042] Specifically, the threaded hole 84 passes through the first fastening bracket 81 and the second fastening bracket 82, and the fastening bolt 85 is threaded through the threaded hole 84. During installation, tightening the fastening bolt 85 causes the first fastening bracket 81 and the second fastening bracket 82 to generate a pulling force that brings them closer together, thereby clamping the support side 21 and the fixed side 23 to achieve a fast connection.

[0043] Furthermore, the first fastening bracket 81 and the second fastening bracket 82 form a U-shape, and the U-shaped groove formed by the first fastening bracket 81 and the second fastening bracket 82 locks the supporting side 21 and the fixed side 23.

[0044] In the specific technical solution, the first fastening frame 81 and the second fastening frame 82 in the easy-lock structure 8 are fixedly connected by the limiting edge 83 to form an integral fastening structure. The first fastening frame 81 and the second fastening frame 82 form a U-shape, and their slots tightly lock the supporting edge 21 and the fixed edge 23 to achieve the initial positioning and clamping of the connection part.

[0045] A further technical solution involves the fastening bolt 85 having its threaded through the first fastening bracket 81, the second fastening bracket 82, and the locking screw hole 22. The fastening bolt 85 also has its threaded through the locking screw hole 22, further enhancing the stability of the connection. Under external forces such as earthquakes, this ensures that the supporting edge 21 and the fixed edge 23 will not loosen or separate, maintaining the integrity and stability of the keel structure.

[0046] This earthquake-resistant keel and its easy-locking structure achieve earthquake resistance and stable connection through the coordinated work of multiple components. Its working principle is as follows:

[0047] Working principle of earthquake-resistant keel

[0052] Shock absorption and cushioning effect:

[0053] The locking block 3 is installed above the support plate 2, and an installation gap 4 is formed between adjacent locking blocks 3. The arc-shaped damping plate 5 is installed in the installation gap 4, and a connecting piece fixing block 6 is locked on its surface. The main body of the keel 7 is riveted on top. When an earthquake occurs, the arc-shaped damping plate 5 uses its own arc structure to undergo elastic deformation, effectively dissipating and buffering the earthquake energy, reducing the seismic force transmitted to the main body of the keel 7, and preventing the main body of the keel 7 from being damaged due to stress concentration.

[0057] Fastening connection achieved:

[0058] The threaded hole 84 passes through the first fastening bracket 81 and the second fastening bracket 82, and the threaded bolt 85 passes through the threaded hole 84. During installation, tightening the fastening bolt 85 causes the first fastening bracket 81 and the second fastening bracket 82 to generate a pulling force that brings them closer together, thereby clamping the support side 21 and the fixed side 23 to achieve a fast connection.
