[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-2 , a composite steel structure exterior wall panel in this embodiment includes a plate body 1 and a connecting frame 2, and the plate body 1 is inserted into the inner side of the connecting frame 2;

[0024] A connecting member 3 for limiting and fixing the plate body 1 is arranged on the connecting frame 2;

[0025] The plate body 1 is composed of two heat preservation boards 11 and heat preservation cotton 12. The two heat preservation boards 11 are fixedly connected to one side and the other side of the heat preservation cotton 12. A fireproof coating is applied to the outer side of the heat preservation board 11, and the fireproof coating is a modified high-chlorinated polyethylene fireproof coating.

[0026] In this embodiment, the plate body 1 composed of two heat preservation boards 11 and one heat preservation cotton 12 improves the heat preservation performance of the entire exterior wall panel. The heat insulation and flame retardant performance is increased by applying the fireproof coating on the outer layer. And through the connecting member 3 located on the outer side of the connecting frame 2, the plate body 1 inserted into the inner side of the connecting frame 2 can be connected and blocked, improving the convenience of splicing the plate body 1.

[0027] Please refer to Figure 1 or 3. In this embodiment, the connecting member 3 includes a support block 32. An installation hole 31 is opened at the lower end of the connecting frame 2. The support block 32 is slidably connected to the inner side of the installation hole 31. A pull rod 33 that penetrates through the support block 32 at one end and extends into the plate body 1 is slidably connected to the outer side of the support block 32. One end of the pull rod 33 located inside the plate body 1 is hinged with a rotating rod 36. A stop rod 38 that penetrates through the rotating rod 36 at one end and extends into the plate body 1 is slidably connected to one side of the rotating rod 36. A rotating ring 39 is rotatably connected to the front surface of the connecting frame 2. A limiting rod 37 located outside the stop rod 38 is fixedly connected to the outer side of the rotating ring 39.

[0028] In this embodiment, when the connecting frame 2 is not blocked by pulling the pull rod 33 and rotating the rotating rod 36, the plate body 1 can be inserted into the inner side of the connecting frame 2. Then, by rotating the rotating rod 36 into the installation groove 34 of the plate body 1, and releasing the limiting rod 37 to block and fix the stop rod 38 extending into the plate body 1. On the contrary, by rotating the limiting rod 37 to push out the stop rod 38 and pulling the pull rod 33, the plate body 1 can be withdrawn, improving the convenience of splicing the plate body 1.

[0029] Among them, the front side of the plate body 1 is provided with a mounting groove 34 located outside the rotating rod 36, the mounting hole 31 is convex-shaped, and the pull rod 33 is U-shaped. The two ends of the U-shaped pull rod 33 block and limit the plate bodies 1 on both sides.

[0030] In addition, the connecting frame 2 is a steel frame, the connecting frame 2 is I-shaped, the limiting rod 37 is L-shaped, and the end of the blocking rod 38 close to the L end of the limiting rod 37 is L-shaped, which is convenient for the operator to move the L end of the blocking rod 38 to extend it into the plate body 1 or separate from the plate body 1.

[0031] Secondly, a retaining groove is formed on the front of the plate body 1, one end of which is connected to the installation groove 34 and is located outside the retaining rod 38. The end of the retaining rod 38 located inside the retaining groove is inclined, so that the rotating rod 36 can drive the inclined end of the retaining rod 38 to be squeezed into the retaining groove.

[0032] Then, a connection groove is formed on the front of the plate body 1, one end of which is connected to the mounting groove 34 and is located outside the L end of the blocking rod 38. The connection groove is arc-shaped, so that the L end of the blocking rod 38 has space to move up and down.

[0033] Finally, a groove is opened on the front side of the connecting frame 2, and the rotating ring 39 is connected to the inner side of the groove by rotating through a rotating shaft. A torsion spring is arranged between the back side of the rotating ring 39 and the inner side of the groove, so that the rotating ring 39 located on the inner side of the groove can be rotated through the rotating shaft and reset by the torsion spring.

[0034] It should be noted that a mounting block is fixedly connected to one side of the connecting frame 2 close to the pull rod 33, and a mounting hole 31 is opened on the mounting block to facilitate the upper and lower docking of the connecting frame 2 and the plate body 1, and the bottom connecting frame 2 and the plate body 1 can be fixed on the base through the mounting block.

[0035] The working principle of the above embodiment is:

[0036] Since the connecting frame 2 is in an I-shape, the board body 1 can be inserted into the inner side of the connecting frame 2 by pulling the pull rod 33 and rotating the rotating rod 36 without blocking the inner side of the connecting frame 2, and then the board body 1 can be blocked and fixed by rotating the rod 36 into the installation groove 34 of the board body 1, and loosening the limit rod 37 to block and fix the blocking rod 38 extending to the inside of the board body 1. Conversely, the limit rod 37 is rotated to push out the blocking rod 38, and the pull rod 33 is pulled to pull out the board body 1, so as to improve the convenience of splicing the board body 1. Since the board body 1 is connected and fixed by two insulation boards 11 and insulation cotton 12, and a fire-retardant coating is applied on the outer side of the insulation board 11, the thermal insulation performance of the entire board body 1 is improved, thereby improving the thermal insulation effect.
