This door design is often used in laboratories, hospitals, industrial facilities, and special environments to ensure the safety and protection of personnel and the environment.

[0003] A protective sealed door disclosed in the Chinese utility model patent application disclosure CN219974301U can ensure that the protective door is effectively fixed between the walls by setting a door frame, and can make the threshold and the protective door fit together by setting a threshold, so that the gap between the protective door and the wall is effectively sealed, and at the same time, through the rotatability of the threshold, when the protective door needs to be opened, the threshold rotates to form a speed bump laid on the ground, but the overall strength of the protective sealed door is low, and the influence of external forces or corrosion due to long-term use will reduce the overall safety and durability of the protective sealed door, thereby posing certain safety hazards. Utility Model Content

[0004] The utility model aims to provide a steel-concrete composite structure protective airtight door to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel-concrete composite structure protective closed door, comprising an outer frame, the outside of the outer frame is provided with a through groove, the inside of the through groove is provided with a sealing structure, a main door leaf is provided at a middle position inside the outer frame, heat-conducting blocks are fixedly connected to both sides of the outside of the main door leaf, and heat-conducting blocks are provided inside with thermal expansion adhesive.

[0006] Preferably, the sealing structure comprises a first rubber pad arranged inside the through groove, an elastic layer is arranged inside the first rubber pad, and a second rubber pad is arranged inside the elastic layer.

[0007] Preferably, the main door leaf includes a supporting layer arranged at a middle position inside the outer frame, and a covering layer is arranged outside the supporting layer.

[0008] Preferably, a filling layer is arranged outside the coating layer, and a strength layer is arranged outside the filling layer.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. This steel-concrete composite structure protective closed door can increase the overall strength of the protective closed door by arranging an outer frame on the outside of the main door leaf. At the same time, a supporting layer, a coating layer, a filling layer, and a strength layer are arranged inside the main door leaf. The supporting layer is coated with a coating layer on the outside to have corrosion resistance and easy cleaning properties, and at the same time protect the supporting layer from the influence of chemicals. A filling layer is arranged on the outside of the coating layer to have light weight and excellent thermal insulation performance, and a strength layer is arranged on the outside of the filling layer to increase the structural strength and durability of the protective closed door. The setting of the combined structure not only improves the protective performance of the door, but also increases the thermal insulation and sound insulation of the door, and improves the overall stability of the protective closed door;

[0011] 2. This kind of steel-concrete composite structure protective closed door has heat-conducting blocks on both sides of the outside of the main door leaf. When the heat-conducting blocks are affected by external heat, they can heat the thermal expansion adhesive in the outer frame. At this time, the heated expansion of the thermal expansion adhesive can push the sealing structure to fill the through grooves on the outer frame and the inside of the door frame, thereby fully sealing the protective closed door, effectively preventing the spread of fire, and ensuring the safety of the use of the protective closed door.
