[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, the embodiment of the utility model proposes an assembled steel structure for construction with a protective function, including a support column 1, a support side plate 2, a connection protection component and a shock-absorbing component: an annular fastener 3 is mounted on the outer wall of the support column 1, the support column 1 adopts a hollow structure, the annular fastener 3 is fixedly connected to the middle side wall of the support column 1, the cross-section of the support side plate 2 is an I-shaped arrangement, and a plurality of threaded mounting holes 4 are provided on the support side plate 2; the connection protection component includes a fastening bolt 5 threadedly connected to the side wall of the annular fastener 3, a threaded sleeve 6 is provided on the rear side of the annular fastener 3, the fastening bolt 5 can be threadedly connected in the threaded mounting hole 4 and the threaded sleeve 6, and the number of the fastening bolt 5 and the threaded mounting hole 4 is three, a sliding groove 7 is provided on the annular fastener 3, a protective cover 8 is slidably connected in the sliding groove 7, the protective cover 8 is slidably connected to both sides of the fastening bolt 5, and a baffle 12 is provided on the top of the protective cover 8, and an opening is provided at the bottom of the protective cover 8;

[0026] First, place the supporting side plate 2 into the annular fastener 3, and make the threaded mounting hole 4 on the supporting side plate 2 correspond to the position of the fastening bolt 5. At this time, pull the protective cover 8 upward, and then rotate the fastening bolt 5 so that the fastening bolt 5 is threadedly connected with the threaded mounting hole 4 and the threaded sleeve 6 in sequence, so as to fully install the fixed column supporting side plate 2, and then loosen the protective cover 8 so that the baffle 12 on the protective cover 8 is against the top of the annular fastener 3. The fastening bolt 5 can be protected by the protective cover 8 to prevent external factors such as rain from rusting the fastening bolt 5 as much as possible, thereby effectively protecting the bolt connection structure and ensuring the stability of the overall steel structure.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the shock absorbing assembly includes a compression spring 9 fixedly connected to the inside of the annular fastener 3, a pressure plate 10 is fixedly connected to the end of the compression spring 9, the side of the pressure plate 10 is arranged in an arc shape, and a buffer pad 11 is arranged on the surface of the pressure plate 10. The compression spring 9 adopts an alloy steel spring with a high elastic coefficient, and the buffer pad 11 is made of EVA foam material;

[0028] During the installation of the supporting side plate 2, the surface of the supporting side plate 2 first contacts and squeezes the pressure plate 10, so that the pressure plate 10 pushes the compression spring 9, and then the compression spring 9 is gradually compressed, and the supporting side plate 2 continues to enter the annular fastener 3. Since the compression spring 9 is made of alloy steel with a high elastic coefficient, the compression spring 9 pushes the pressure plate 10 to press the supporting side plate 2. When external vibration occurs, the supporting side plate 2 is first cushioned by the pressure plate 10 and the compression spring 9 due to the influence of the vibration, thereby avoiding the loosening of the connection structure inside the annular fastener 3 as much as possible, improving the stability of the steel structure and extending the service life.

[0029] The detailed working process of the utility model is as follows:

[0030] 1. When in use, first place the supporting side plate 2 into the annular fastener 3, and make the threaded mounting hole 4 on the supporting side plate 2 correspond to the position of the fastening bolt 5. At this time, pull the protective cover 8 upward, and then rotate the fastening bolt 5, so that the fastening bolt 5 is threadedly connected with the threaded mounting hole 4 and the threaded sleeve 6 in sequence, so as to fully install the fixed column supporting side plate 2, and then loosen the protective cover 8, so that the baffle 12 on the protective cover 8 is against the top of the annular fastener 3. The fastening bolt 5 can be protected by the protective cover 8, and the external factors such as rainwater can be prevented from rusting the fastening bolt 5 as much as possible, thereby effectively protecting the bolt connection structure and ensuring the stability of the overall steel structure.

[0031] 2. During the installation of the supporting side plate 2, the surface of the supporting side plate 2 first contacts and squeezes the pressure plate 10, so that the pressure plate 10 pushes the compression spring 9, and then the compression spring 9 is gradually compressed, and the supporting side plate 2 continues to enter the annular fastener 3. Since the compression spring 9 is made of alloy steel with a high elastic coefficient, the compression spring 9 pushes the pressure plate 10 to press the supporting side plate 2. When external vibration occurs, the supporting side plate 2 is first cushioned by the pressure plate 10 and the compression spring 9 due to the impact of the vibration, thereby avoiding the loosening of the connection structure inside the annular fastener 3 as much as possible, improving the stability of the steel structure and extending the service life.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
