Steel structure protective air-tight door with good impact resistance and working method of steel structure protective air-tight door

Abstract

The invention discloses a steel structure protective air-tight door with good impact resistance and a working method thereof, relates to the technical field of air-tight doors, and aims to solve the problem that an existing protective air-tight door is poor in use practicability and use feeling due to poor impact resistance. The steel structure protective air-tight door assembly comprises an upper mounting frame strip, a lower mounting frame strip connected with the two ends of the upper mounting frame strip, a right mounting frame strip and a left mounting frame strip, wherein the right mounting frame strip and the left mounting frame strip are connected between the upper mounting frame strip and the lower mounting frame strip. The fastening connection structures are in flange connection with the inner walls of the right mounting frame strip and the left mounting frame strip respectively; the connecting rod component is connected to the fastening connecting structure in an embedded and inserted mode, and a hinge structure is connected to the connecting rod component in a hoop mode; the protective air-tight door component is connected to the hinge structure through a flange; the rudder-shaped switch structure is connected to the protective air-tight door component in an embedded mode, and meanwhile the door opening handle component is connected to the surface of the protective air-tight door component in a welded mode.

Description

technical field [0001] The invention relates to the technical field of airtight doors, in particular to a steel structure protective airtight door with good impact resistance and a working method thereof. Background technique [0002] The protective airtight door is a protective structure that is set at the outermost side of the entrance and exit and has two functions of blocking shock waves and isolating poisons; for example, when resisting shock waves, the main function of the protective airtight door is to block shock waves and meet the corresponding resistance requirements. In the case of toxic gas, the main function of the protective airtight door is to block the toxic gas. In addition, most of the steel protective airtight doors are of the flat-opening type. According to the number of door leaves, they can be divided into: single airtight airtight doors and double airtight airtight doors. Type; single-leaf airtight doors are generally smaller in size and suitable for p...
