Air-tight door based on encryption type protective concrete

Abstract

The invention relates to the technical field of building construction, and discloses an air-tight door based on encryption type protective concrete. The air-tight door based on the encryption type protective concrete structurally comprises a door plate, a base block, a hand-pull handle, a key lock, glass, a sealing strip, a door frame and an encryption device. The front surface of the door plate is welded to and mutually parallel to the rear surface of the base block, the hand-pull handle is connected with the key lock through the base block, and the glass outer side surface is nested with theinner side surface of the sealing strip. The encryption device is mounted in the door frame in a fitting mode, the sealing strip is mounted in front of the door plate in a welding mode, the key lockis arranged on the left side surface of the glass, and the sealing strip is made by rubber. The encryption device structurally comprises a protective shell, a transmission rod, a fixed block, a compressing sleeve and a counterpoint rod, and the transmission rod is mounted on the inner surface of the interior of the protective shell in a welding mode and mutually perpendicular to the protective shell. Compared with the prior art, through the cooperation of an encryption block and an object removal device, a force transferring source of an upper door shaft is used, encryption of cracks is achieved, and the encryption block can be rapidly overhauled matching with rubber bands.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an airtight door based on encrypted protective concrete. Background technique [0002] Concrete can be used in many ways. Too much concrete is difficult to use up at one time. At this time, it needs to be stored in the concrete standard curing room. For this, first open the airtight door of the concrete standard curing room, and then manually carry it through the airtight The door is placed indoors, and finally stored through the indoor air supply and return air system. [0003] In this prior art, after all the concrete is transported to the interior of the concrete standard curing room, the airtight door is closed immediately. After closing, there will be a gap between the airtight door and the room, and the inside and the outside will form a mutual flow through the gap. , so that when the internal air supply and return air system is running, it will be affected t...
