Specifically, the base 4 can be rod-shaped or cross-shaped, and is generally welded to the steel structure for fixation. One end of the fixing screw 3 is provided with a fixing cap 5. The end of the fixing screw 3 sequentially passes through the insulation board 2 and the fixing plate 1 and is threadedly connected to the fixing cap 5. One side of the insulation board 2 contacts the exterior wall of the steel structure, and the other side uses the cooperation of the fixing cap 5 and the fixing screw 3 to fix the fixing plate 1 on the surface of the insulation board 2. Specifically, through holes are provided at the centers of both the insulation board 2 and the fixing plate 1. After the fixing screw passes through the through holes, it is threadedly connected to the fixing cap 5, so that the insulation board 2 and the steel structure are connected by the fixing screw 3. At the same time, the fixing plate 1 is in contact with the connection position between the fixing screw 3 and the insulation board 2, thereby increasing the contact fixing area of the insulation board 2, improving the fixing effect on the insulation board 2, reducing the possibility of tearing at the through hole position on the insulation board 2, ensuring the service life of the fixing device for the insulation board 2. A plurality of fixing plates 6 are slidably connected to the fixing plate 1 along the radial direction. The fixing plates 6 extend along the radial direction of the fixing plate 1. One end of the fixing plate 6 is provided with an anchor bolt 7 connected to the insulation board 2. The anchor bolt 7 passes through the fixing plate 6 and is fixed on the insulation board 2. The fixing plate 1 is provided with a limiting plate 8 that cooperates with a plurality of fixing plates 6 at the same time. Such a structure can slide the fixing plates 6 according to actual usage requirements when fixing insulation boards 2 of different sizes, so that the ends of the plurality of fixing plates 6 extend to the edges of the insulation board 2 and are fixed by the anchor bolts 7, and then the limiting plate 8 is used to limit and fix the plurality of slid fixing plates 6, so that the overall formed by the fixing plate 1 and the plurality of fixing plates 6 better covers each position of the insulation board 2, thereby further improving the fixing effect on insulation boards 2 of different sizes and enhancing the adaptability and application range of the device.

[0022] Preferably, referring to Figure 3 , a plurality of sliding grooves 9 are arranged in an array inside the fixing plate 1. The sliding grooves 9 extend along the radial direction of the fixing plate 1. The fixing plates 6 are slidably connected in the sliding grooves 9. Such a structure enables the sliding structure of the fixing plates 6 to be arranged inside the fixing plate 1, so that when applying and covering mortar on the outside of the fixing plate 1 and the insulation board 2, it will not directly contact the sliding structure, thereby avoiding cracks that may occur in the external covering mortar due to relative shaking of the sliding structure and ensuring the overall integrity of the building exterior.

[0023] Preferably, a plurality of through positioning holes 10 are provided on the fixing plate 6, and the plurality of positioning holes 10 are linearly arrayed along the length direction of the fixing plate 6.

The fixing screw 3 sequentially passes through the heat preservation plate 2, the fixed disk 1, and the limiting plate 8 and is threadedly connected with the fixing cap 5. Such a structure uses the fixing screw 3 to fix the limiting plate 8 and the fixed disk 1 at the same time, and the fixed cooperation between the limiting plate 8 and the fixed disk 1 can be realized without an additional fixing structure, simplifying the complexity of the fixing device, enabling the limiting plate 8 to be synchronously fixed in the installation groove 12 on the fixed disk 1, and improving the convenience and firmness of the connection and fixation of the limiting plate 8.

[0025] Preferably, a plurality of counterbores 13 are provided at the bottom of the installation groove 12, and the counterbores 13 are recessed inward from the bottom of the installation groove 12. The positioning posts 11 are movably inserted into the counterbores 13 after passing through the positioning holes 10. When the limiting plate 8 is placed inside the installation groove 12, such a structure enables the plurality of limiting posts on it to respectively pass through the limiting holes on the plurality of fixing plates 6 and be inserted into the corresponding counterbores 13, so that the connection structure between the limiting plate 8 and the fixed disk 1 is more firm, avoiding the possible misalignment movement of the limiting plate 8 relative to the fixed disk 1, and improving the firmness of the fixing device.

[0026] Preferably, a backing plate 14 is integrally formed and fixed at the end of the fixing plate 6, and the backing plate 14 is in contact with the heat preservation plate 2. The setting of the backing plate 14 can make up for the gap between the fixing plate 6 and the heat preservation plate 2 and avoid the end of the fixing plate 6 from being in a suspended state.

The other end of the fixing screw 3 sequentially passes through the insulation board 2 and the fixing plate 1 and is threadedly connected to the fixing cap 5. Such a structure, on the one hand, strengthens the connection structure between the insulation board 2 and the steel structure by using the fixing screw 3, avoiding the separation of the insulation board 2 from the steel structure, reducing the phenomena of cracking, hollowing and falling off of the insulation board 2, improving the firmness of the insulation board 2. At the same time, the setting of the fixing plate 1 further increases the contact area between the fixing screw 3 and the insulation board 2, improving the fixing effect of the fixing screw 3 on the insulation board 2. After long-term use, cracks are not easily formed at the position where the insulation board 2 is penetrated, improving the service life of the fixing structure of the insulation board 2; A plurality of fixing plates 6 are slidably connected along the radial direction on the fixing plate 1.
