Fireproof and smokeproof fire-fighting roller shutter door

Abstract

The invention discloses a fireproof and smokeproof fire-fighting roller shutter door which comprises a box body, a reel, a motor, a linkage sheet, a smoke baffle plate, a pressing plate and fireproofcoatings, wherein the box body is mounted and fixed on a wall body; the reel is mounted on the right side of a side plate; the linkage sheet is fixed on the reel; the tops of two ends of a guide railare connected with the box body; the bottom end of the guide rail is fixed on a foundation; a handle is mounted on the surface of the lower part of the linkage sheet; the bottom of the linkage sheet is clamped in the foundation; the smoke baffle plate is mounted on the upper surface of the inner side of the foundation and set to be an arc-shaped structure; and the pressing plate is connected withthe upper side of the smoke baffle plate and set to be a horizontal structure. Both the inner wall and the outer wall of the fireproof and smokeproof fire-fighting roller shutter door are coated withthe fireproof coatings, so that the fireproof effect on the door body of the fireproof and smokeproof fire-fighting roller shutter door can be achieved; and furthermore, the arc-shaped smoke baffle plate is arranged at the position where the lowest end of the linkage sheet of the door body is connected with the ground, so that the blocking effect on dense smoke can be achieved when the linkage sheet moves down till the pressing plate is pressed to bend the smoke baffle plate.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a fire-proof and smoke-insulating fire-fighting rolling door. 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. Rolling shutter doors are usually widely used in shops. The rolling shutter door plays the role of horizontal separation like the wall. It consists of a curtain plate, a seat plate, a guide rail, a support, a reel, a box body, a control box, a rolling door machine, a limiter, a lintel, a manual quick-release switch device, and a button switch. It is composed of multiple parts such as safety device and so on, and is generally installed in places where it is inconvenient to use walls to separate. [0003] But existing rolling shutter door all can leave gap between installation and installation frame and b...

Problems solved by technology

[0003] However, the existing rolling shutter door will leave gaps between the installation and the installation frame, as well as between the bottom and the ground, so that in the event of a fire, thick smoke can still pass through the gaps
