AI Technical Summary

Technical Problem

The overall strength of the existing protective sealed door is low, and it is easily affected by external forces or corrosion caused by long-term use, which reduces safety and durability and poses safety hazards.

Method used

It adopts a steel-concrete combination structural design, including the outer frame, main door leaf and sealing structure. A through groove is provided outside the outer frame, and a sealing structure is provided inside; a support layer, a cladding layer, a filling layer and a strength layer are provided inside the main door leaf; thermal conductive blocks and thermal expansion glue are used for filling and sealing of the sealing structure.

Benefits of technology

By increasing the strength layer of the outer frame and main door leaf, the overall strength and durability of the protective sealed door are improved; the design of the sealing structure improves the sealing effect, prevents the spread of fire, and enhances safety and sound insulation.

Abstract

The utility model discloses a steel-concrete composite structure protective airtight door which comprises an outer frame, a through groove is formed in the outer portion of the outer frame, a sealing structure is arranged in the through groove, a main door leaf is arranged in the middle of the interior of the outer frame, and heat conduction blocks are fixedly connected to the two sides of the exterior of the main door leaf. The overall strength of the protective air-tight door can be improved by arranging the outer frame outside the main door leaf, meanwhile, the supporting layer, the wrapping layer, the filling layer and the strength layer are arranged inside the main door leaf, the wrapping layer is coated outside the supporting layer, so that the protective air-tight door has corrosion resistance and is easy to clean, meanwhile, the supporting layer is protected against the influence of chemicals, and the service life of the protective air-tight door is prolonged. The filling layer is arranged outside the coating layer and has light weight and excellent heat insulation performance, the strength layer is arranged outside the filling layer, the structural strength and durability of the protective airtight door are improved, and through the arrangement of the combined structure, the protective performance of the door is improved, and the heat insulation performance and the sound insulation performance of the door are improved.
