Embodiment Construction

[0018] The large-span lifting inorganic fireproof rolling door of the present invention includes a scrolling shaft 6 and a door curtain 1. The door curtain 1 acts as a shield. The scrolling shaft 6 rotates to drive the door curtain to be lowered to form a shield or to be lifted to form a passage. When forming a shield, it can not only prevent people from entering and leaving, but also It can also block the passage of the fire. The door curtain 1 includes a curtain 9 and a lifting belt 5. The uppermost end of the curtain 9 can be fixed on the wall of the door opening to reduce the load of the curtain itself on the rolling shaft. and is positioned by the limit device 4, so that the lifting belts 5 are evenly spaced without moving laterally to form the winding of the lifting belts 5 intervals, one end of the lifting belt 5 is fixed to the bottom of the curtain to drive the bottom to move, and the other end of the lifting belt 5 is fixed on the On the scrolling shaft 6, when the sc...

Abstract

The large span fireproof roller shutter is suitable for large span frame and for partitioning fireproof areas. It includes rolling shaft and curtain, and the curtain includes curtain fabric and longitudinally arranged raising strips. On the curtain fabric, there are position limiter to fix the raising strips and horizontal pressing strips. Each of the raising strips has one end fixed to the bottom of the curtain fabric for folding and moving the fabric and the other end fixed onto the rolling shaft support by one or several bearings in the middle part. Owing to the support in the middle part, the roller shutter may have large span and greatly lowered rolling resistance being favorable to manual operation.

Description

technical field [0001] The invention relates to a fire-proof rolling door, in particular to a large-span lifting inorganic fire-proof rolling door, which is especially suitable for the fire-proof rolling door with a large-span frame or space as a partition of a fire-proof area. Background technique [0002] Existing rolling doors or fire-proof rolling doors are structurally designed to lift or lower the curtain through the rotation of the shaft. There can be no gaps or holes, so that the entire shaft is completely covered by winding on the shaft. Except for the support at both ends of the shaft, the rest of the shaft cannot be supported. Due to the heavy fire door curtain, it is not suitable for large-span spaces. Setting the rolling shutter will lead to insufficient load bearing of the shaft; now a solution is to use a thicker shaft, as a result, the use of materials increases, and a high-power motor has to be used, but the thickening of the shaft is limited, which is often...
