Shock-resisting steel explosion-venting rolling shutter door

Abstract

The invention relates to a shock-resisting steel explosion-venting rolling shutter door comprising a drive system (1), wherein the drive system (1) is arranged on a support plate (5); the support plate (5) is fixedly arranged on the wall of a building; one end of a curtain surface (2) is arranged on the drive system (1); and two sides of the curtain surface (2) extend into notches (301) of open-type guide rails (3) and are capable of moving in the notches (301) of the open-type guide rails (3). The rolling shutter door is characterized in that the open-type guide rails (3) comprise installation parts (302) and explosion venting parts (303) which are connected through hinges (304); and explosion venting devices (305) are arranged between the installation parts (302) and the explosion venting parts (303). The shock-resisting steel explosion-venting rolling shutter door provided by the invention has the advantages that the requirements that the open and the close of the door are easy in normal use and large-size objects can pass are satisfied; and when an explosion accident happens, the curtain surface can be opened by shock wave to realize good explosion venting and pressure releasing functions.

Description

technical field [0001] The invention belongs to the technical field of building components, and in particular relates to an impact-resistant steel explosion-venting rolling door used for building entrances and passages with explosion risks, which can avoid or weaken the damage to buildings caused by shock waves generated by explosions, and provide protection for property and Provide effective protection for personnel safety. Background technique [0002] The rolling shutter door is made of multi-joint movable door pieces connected in series. In the fixed slideway, the upper and lower doors are rotated around the reel above the door. The rolling shutter door acts as a horizontal partition in the same way as the wall. It consists of a curtain plate, a seat plate, a guide rail, a support, a reel, a box, a control box, a rolling door machine, a limiter, a door lintel, a manual quick-release switch device, and a button switch. It is composed of 13 parts, including safety device,...

Problems solved by technology

[0004] Aiming at the technical defect that the existing traditional explosion-venting doors and windows cannot be made into large sizes in order to meet the requirements of anti-explosion shock wave, the present invention provides an impact-resistant steel explosion-venting rolling door, which is easy to open and close during normal use, and realizes large It meets the requirements of acceptable size, and in the event of an explosion, the curtain surface is opened by the shock wave, which plays a good role in explosion and pressure relief.
