[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 and Figure 4This utility model provides an embodiment of a steel structure factory roof purlin reinforcement structure, including a purlin body 1, a steel plate 9 at the bottom of the purlin body 1, a reinforcing member 10 at the rear end of the purlin body 1, and a reinforcing member 11 at the rear side of the reinforcing member 10 for reinforcement. Multiple bolts 12 are threadedly connected to the front end of the steel plate 9, and nuts 13 are threadedly connected to the rear end of the bolts 12. Multiple bolts 14 are threadedly connected to the left and right sides of the front end of the purlin body 1, and nuts 15 are threadedly connected to the rear side of the bolts 14 for fixation. A buffer mechanism 2 is provided at the bottom end of the purlin body 1 to buffer the factory roof purlin reinforcement structure. Steel bars 4 are provided on the left and right sides of the front end of the base steel plate 3.

[0040] Specifically, during the reinforcement operation of the steel structure factory roof purlin reinforcement structure, a steel plate 9 is first placed below the purlin body 1. After the connection point of the purlin body 1, a reinforcing member 10 is placed sequentially. Behind the reinforcing member 10, a second reinforcing member 11 is placed. Through this layering, the reinforcement effect is gradually achieved. To ensure a firm connection between the components, multiple bolts 12 are installed at the front end of the steel plate 9 using a threaded connection. The bolts 12 need to pass through the purlin body 1, the reinforcing member 10, and the second reinforcing member 11 sequentially to achieve a tight connection between the components. The threads at the rear end of the bolts 12 are used for this connection. The nuts 13 are tightened to ensure the stability of the connection. On the left and right sides of the purlin body 1, bolts 14 are installed by threaded connection. Bolts 14 need to penetrate the purlin body 1, reinforcement 10 and reinforcement 11. The rear end of bolts 14 is further tightened by threaded connection to nuts 15. This makes the operation of the entire node simple and convenient, avoids damage to the original roof panel and purlin structure, effectively improves the load-bearing capacity of the roof purlin, and significantly reduces the cost of the renovation project. Steel bars 4 are carefully set on the left and right sides of the front end of the base steel plate 3 to further enhance the stability and reliability of the overall structure.

A base plate 202 is fixedly connected to both the left and right ends of the housing 201. A support plate 203 is rotatably connected to both the front and rear ends of the base plate 202. A clamp spring 204 is installed at the upper end of the support plate 203. A support plate 205 is rotatably connected to the top of the support plate 203 for secondary buffering. A buffer top plate 206 is rotatably connected to the top of the support plate 205. A buffer column 207 is fixedly connected to the upper middle part of the base plate 202. A telescopic column 208 is slidably connected to the upper end of the buffer column 207 for buffering. The telescopic column 208 is fixedly connected to the buffer top plate 206. A buffer spring 209 is fixedly connected to the bottom of the base plate 202 for auxiliary buffering. The other end of the buffer spring 209 is fixedly connected to the buffer top plate 206. A buffer plate 210 is installed at the top of the buffer top plate 206. A base steel plate 3 is located at the bottom of the housing 201.

[0042] Specifically, when the steel structure factory roof purlin reinforcement structure requires buffering, the base plates 202 located on the left and right sides inside the casing 201 are rotatably connected to the support plate 203 to achieve a telescopic function. A clamp spring 204 is installed above the support plate 203 to provide auxiliary support. A second support plate 205 is further connected above the clamp spring 204, and the second support plate 205 is then rotatably connected to the buffer top plate 206, thus achieving a second buffering effect. A buffer column 207 is fixed at the upper middle part of the base plate 202. The top of the buffer column 207 is slidably connected to the telescopic column 208, undertaking the main buffering task. In addition, a buffer spring 209 is fixed below the base plate 202, and the other end of the buffer spring 209 is connected to the buffer top plate 206 to further assist in buffering. A buffer plate 210 is also set above the buffer top plate 206 to place related components, ensuring the stability and effectiveness of the entire buffering equipment, ensuring that the roof purlin reinforcement structure of the factory can effectively buffer when subjected to external forces, and extending its service life. A base steel plate 3 is also specially set at the bottom of the casing 201 to enhance the stability of the overall structure.

[0043] Reference Figure 2 and Figure 3 The upper end of the steel bar 4 is threaded with bolt 3 5; the rear end of bolt 3 5 is threaded with nut 3 6 for fixing; the bottom of the steel bar 4 is threaded with bolt 4 7; the rear end of bolt 4 7 is threaded with nut 4 8.

[0044] Specifically, the upper part of steel bar 4 is connected to bolt 3 5 through a threaded structure, ensuring the stability and reliability of the entire component. The rear end of bolt 3 5 is also connected to nut 3 6 through a threaded method, effectively preventing loosening. The bottom of steel bar 4 is also equipped with a threaded interface for connecting bolt 4 7, which enhances the overall strength of the structure. The rear end of bolt 4 7 is also connected to nut 4 8 through a thread, ensuring excellent performance under various working conditions.

[0045] Working principle: When reinforcing the roof purlins of a steel structure factory building, the steel plate 9 is placed under the purlin body 1 for initial placement. Reinforcing member 10 is placed behind the connection of the purlin body 1, and reinforcing member 21 is placed behind reinforcing member 10 for reinforcement. Multiple bolts 12 threaded in front of the steel plate 9 pass through the purlin body 1, reinforcing member 10 and reinforcing member 21 to connect them. Nuts 13 threaded behind bolts 12 are used for tightening and fixing. Bolts 24 threaded on the left and right sides of the purlin body 1 pass through the purlin body 1, reinforcing member 10 and reinforcing member 21. Nuts 25 threaded behind bolts 214 are used for tightening and fixing. This method achieves simple and easy operation of the nodes, avoids damage to the original roof panels and purlins, increases the load-bearing capacity of the roof purlins and reduces the cost of renovation.

[0046] When the steel structure factory roof purlin reinforcement structure is buffered, the base plates 202 on the left and right sides inside the casing 201 are connected to the support plate 203 by rotation at the front and rear sides for telescopic movement. A clamp spring 204 is installed on the support plate 203 for auxiliary function. The clamp spring 204 is connected to the support plate 205 by rotation at the top, and the support plate 205 is connected to the buffer top plate 206 by rotation at the top for secondary buffering. A buffer column 207 is fixed in the middle and upper part of the base plate 202. The buffer column 207 is slidably connected to the telescopic column 208 for primary buffering. A buffer spring 209 is fixed at the bottom of the base plate 202. The other end of the buffer spring 209 is fixed to the buffer top plate 206 for auxiliary buffering. A buffer plate 210 is installed on the buffer top plate 206 for placement. This achieves the buffering effect on the factory roof purlin reinforcement structure.
