Description

Technical Field

[0001] This utility model relates to the field of steel frame technology, and in particular to a steel frame anti-collapse structure that can improve seismic performance. Background Technology

[0002] In the construction industry, steel frame structures play a crucial role, widely used to support roof slabs and ensure the stability and durability of building structures. This structural system is typically composed of high-strength steel beams and columns, seamlessly connected using precise bolting technology. The steel beams, cleverly positioned between two steel columns, not only bear the weight of the roof but also, through their unique groove design, provide a stable and precise platform for the roof slab.

[0003] However, the widely used steel frame structure connection methods currently rely heavily on the fixing combination of support plates and bolts. Although this connection method exhibits good stability and reliability under normal use conditions, its structural integrity faces severe challenges when facing extreme natural disasters such as earthquakes and floods. Because these disasters are often accompanied by strong vibrations and impacts, damage to traditional connection methods can lead to structural disintegration or even collapse, seriously threatening the lives and property of people inside the building, and the overall safety needs to be further improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a steel frame anti-collapse structure that can improve seismic performance.

[0005] An embodiment of this utility model provides a steel frame anti-collapse structure that can improve seismic performance, comprising:

[0006] A steel frame column, wherein a steel frame beam is provided on the side of the steel frame column, and an L-shaped support plate is fixedly provided on both sides of one end of the steel frame beam, and the L-shaped support plate is fixedly provided on the steel frame column.

[0007] Both ends of the L-shaped support plate are equipped with anti-collapse components. The anti-collapse components include a fixing plate and multiple steel cables. The fixing plate is fixedly installed on the steel frame column and steel frame beam. One end of each of the multiple steel cables is fixedly installed on the fixing plate, and the other end of each steel cable is fixedly installed on the L-shaped support plate on the same side.

[0008] Furthermore, both ends of the L-shaped support plate are provided with first bolts, and the first bolts are threaded with first nuts. Several first mounting holes are provided through the steel frame column.

[0009] Furthermore, multiple second bolts are provided through the fixing plate, and second nuts are threaded onto the second bolts. Several second mounting holes are provided through the steel frame columns and steel frame beams.

[0010] Furthermore, each end of the steel cable is fixedly provided with an installation ring, and a third bolt is inserted through each installation ring. Both the fixing plate and the L-shaped support plate are provided with threaded holes, and the steel cable is fixedly connected to the fixing plate and the L-shaped support plate by the third bolt.

[0011] Furthermore, the L-shaped support plate is fixedly connected to the steel frame column by the first bolt, and the fixing plate is fixedly connected to the steel frame column and the steel frame beam by the second bolt.

[0012] Furthermore, a reinforcing plate is fixedly installed inside the L-shaped support plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Anti-collapse components are installed, and the steel cables can play a secondary support role. When the steel frame beams and steel frame columns become loose or separate, the steel cables can effectively pull and fix the steel frame beams, thereby effectively curbing the further disintegration or collapse of the structure, significantly enhancing the overall stability of the structure, providing a solid guarantee for the safety of people inside the building, and improving safety.

[0015] 2. The cable is equipped with threaded holes and third bolts. When replacing the cable, simply unscrew the third bolts at both ends to remove the cable for replacement. Alternatively, pass the two third bolts through the mounting rings at both ends of the cable and screw them into the corresponding threaded holes to secure the cable. The operation is simple and convenient, facilitating replacement and maintenance.

[0016] In summary, this utility model incorporates anti-collapse components, significantly enhancing the overall stability of the structure, ensuring the safety of personnel inside the building, and reducing potential safety risks. Furthermore, the inclusion of threaded holes and a third bolt allows for convenient installation and disassembly of the steel cables, facilitating replacement or maintenance and increasing practicality.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a steel frame anti-collapse structure that can improve seismic performance, including:

[0023] A steel frame column 1 is provided, and steel frame beams 2 are provided on the sides of the steel frame column 1. Both the steel frame column 1 and the steel frame beams 2 are set in an I-shape to ensure good support. L-shaped support plates 3 are fixedly installed on both sides of one end of the steel frame beams 2. Reinforcing plates 6 are fixedly installed inside the L-shaped support plates 3. The reinforcing plates 6 play a crucial role in significantly improving and reinforcing the overall structural strength and stability of the L-shaped support plates 3, providing stronger support. The L-shaped support plates 3 are all fixedly installed on the steel frame column 1. First bolts 4 are threaded through both ends of the L-shaped support plates 3. First nuts 5 are threaded onto the first bolts 4. Several first mounting holes 15 are provided through the steel frame column 1. The first bolts 4 are precisely passed through each first mounting hole 15. The L-shaped support plates 3 cleverly use the passage of the first bolts 4 and the tight tightening of the first nuts 5 to achieve a stable and reliable fixed connection with the steel frame column 1, enhancing the overall stability.

[0024] Both ends of the L-shaped support plate 3 are equipped with anti-collapse components, which include a fixing plate 7 and multiple steel cables 11. The fixing plate 7 is fixedly installed on the steel frame column 1 or steel frame beam 2. Multiple second bolts 9 are threaded through the fixing plate 7, and second nuts 10 are threaded onto the second bolts 9. Several second mounting holes 8 are threaded through the steel frame column 1 and steel frame beam 2. The second bolts 9 pass precisely through each second mounting hole 8. The fixing plate 7 cleverly uses the passage of the second bolts 9 and the tight tightening of the second nuts 10 to achieve a stable and reliable fixed connection with the steel frame column 1 or steel frame beam 2, thereby enhancing the overall stability.

[0025] One end of each of the multiple steel cables 11 is fixed to the fixed plate 7, and the other end of each steel cable 11 is fixed to the L-shaped support plate 3 on the same side. The multiple steel cables 11 are carefully and firmly fixed to the fixed plate 7, and their reasonable layout ensures a balanced distribution of force. The other end of each steel cable 11 is also firmly connected to the L-shaped support plate 3 on the same side. This design not only enhances the overall stability of the structure, but also cleverly utilizes the tension characteristics of the steel cables 11 to further strengthen the connection strength and support effect between the L-shaped support plate 3 and the fixed plate 7. Each steel cable 11 is like a bridge cable, bearing an important support function.

[0026] The steel cable 11 serves as a secondary support. In case of emergencies, such as when the steel frame beam 2 and the steel frame column 1 become loose or even separate, the steel cable 11 can effectively pull and fix the steel frame beam 2, thereby effectively curbing the further disintegration or collapse of the structure. This not only significantly enhances the overall stability of the structure, but also provides a solid guarantee for the safety of people inside the building to a large extent and reduces potential safety risks.

[0027] Both ends of the steel cable 11 are fixedly provided with mounting rings 12, and a third bolt 14 is inserted through the mounting ring 12. The fixing plate 7 and the L-shaped support plate 3 are provided with threaded holes 13. The third bolt 14 is threadedly connected to the threaded holes 13. The steel cable 11 is fixedly connected to the fixing plate 7 and the L-shaped support plate 3 through the third bolt 14.

[0028] The detailed working process of this utility model is as follows:

[0029] When replacing the steel cable 11, firstly, use appropriate tools to loosen and completely remove the third bolts 14 that are used to fix both ends, ensuring that the two third bolts 14 are smoothly separated from the threaded holes 13 to which they are connected. Then, the steel cable 11 can be easily removed from its original position, ready for maintenance or replacement of the new steel cable 11.

[0030] Next, the two third bolts 14 are passed through the mounting rings 12 at both ends of the steel cable 11 one by one, and the two third bolts 14 are screwed into the pre-reserved and matching threaded holes 13 to ensure that the steel cable 11 is firmly and safely fixed in place; through the above careful operation, the replacement and fixing of the steel cable 11 is successfully completed.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
