[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 A connection structure of a steel structure and a prefabricated exterior wall panel comprises a prefabricated exterior wall panel body 1, a steel frame 2 is arranged on the rear side of the prefabricated exterior wall panel body 1, and mounting holes 3 are provided on the front side of the steel frame 2 and the prefabricated exterior wall panel body 1: a rectangular hole 4 is provided in the middle of the prefabricated exterior wall panel body 1, and an mounting unit 5 is arranged on the outer side of the prefabricated exterior wall panel body 1, wherein a plurality of mounting holes 3 are arranged to facilitate the connection of the steel frame 2 and the prefabricated exterior wall panel body 1 together.

[0024] The mounting unit 5 includes a side plate 501, which is fixedly connected to the left and right inner walls of the steel frame 2, and a positioning groove 502 is provided on the rear sides of the left and right side plates 501. A fixing plate 506 is fixedly connected to the inner side of the rectangular hole 4, and a sliding groove 507 is provided on the outer side of the fixing plate 506. Slide plates 509 are slidably connected to the inner sides of the left and right ends of the sliding groove 507. Connecting rods 505 are provided on the outer sides of the left and right slide plates 509. A connecting block 504 is fixedly connected to the rear end of the connecting rod 505, and a positioning block 503 is fixedly connected to the outer side of the connecting block 504. A spring 510 is fixedly connected between the connecting block 504 and the slide plate 509. A telescopic rod 512 is fixedly connected to the front side of the fixing plate 506, and a fixing cylinder 513 is fixedly connected to the front end of the telescopic rod 512. Control panels 514 are provided on the left and right sides of the fixing cylinder 513. A front plate 511 is fixedly connected to the outer side of the control panel 514, and the front plate 511 is fixedly connected to the connecting rod 505. The positioning groove 502 is adapted to the positioning block 503, the connecting rod 505 is slidably connected to the slide plate 509, the control panel 514 is slidably connected to the fixed cylinder 513, the side panel 501 and the connecting block 504 are both L-shaped structures, and the front sides of the left and right control panels 514 are fixedly connected with pull blocks 515. When in use, the staff first places the prefabricated exterior wall panel body 1 on the front side of the steel frame 2. At this time, the positioning block 503 is located on the outside of the side panel 501. At this time, the staff presses down the fixed cylinder 513 to make the fixed cylinder 513 drive the control panel 514 to move, the control panel 514 drives the front panel 511 to move, the front panel 511 drives the connecting rod 505 to move backward, the connecting rod 505 drives the connecting block 504 to move, the connecting block 504 drives the positioning block 503 to move backward, and then the staff pulls the pull block 515. The pulling block 515 drives the control plate 514 to move, and the control plate 514 drives the connecting block 504 on the connecting rod 505 to move, so that the connecting block 504 drives the positioning block 503 to move toward the side plate 501. During the movement, the slide plate 509 slides on the inside of the slide groove 507. When the slide plate 509 moves to the opposite end, it stops moving and releases the hand. At this time, the spring 510 is straightened. Under the action of the elastic force of the spring 510, the spring 510 drives the positioning block 503 to move forward quickly. When the positioning block 503 is in contact with the positioning groove 502, it indicates that the main body 1 of the prefabricated external wall panel and the mounting hole 3 on the steel frame 2 are well positioned. Otherwise, it is convenient for the staff to make adjustments in time and connect it with the side plate 501 through the positioning block 503 to increase the stability of the connection between the main body 1 of the prefabricated external wall panel and the steel frame 2.

[0025] Working principle: When in use, the staff first places the prefabricated exterior wall panel body 1 on the front side of the steel frame 2, and then presses the fixing tube 513 to make the fixing tube 513 drive the positioning block 503 to move backward, and then pulls the left and right control panels 514 to make the control panels 514 drive the positioning block 503 to move to the rear of the positioning groove 502. At this time, the spring 510 is straightened, and then let go to make the positioning block 503 quickly reset. When the positioning block 503 fits with the positioning groove 502, it means that the mounting hole 3 is positioned successfully. Otherwise, it needs to be adjusted to facilitate installation with bolts, and the stability of the connection between the prefabricated exterior wall panel body 1 and the steel frame 2 is increased by limiting the positioning block 503.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
