Abstract
The invention discloses a fireproof curtain structure which comprises a rigid curtain, a main machine base and a guide rail arranged on the side of a stage. The rigid curtain is in sliding fit to theguide rail; a winding reel and a drive motor for driving the winding reel are arranged on the main machine base; a traction steel rope winds on the winding reel; one end of the traction steel rope isfixed to the winding reel; the other end of the traction steel rope is connected with the rigid curtain; multiple escape structures are arranged on the lower end of a fireproof plate; each escape structure comprises an escape straight slot and a push-open small door for sealing the escape straight slot; the lowest point of each push-open small door and the lowest point of the rigid curtain are inthe same horizontal surface; in one escape structure, the upper end of the push-open small door is hinged with the rigid curtain through a hinge shaft, and the axis of each hinge shaft is horizontal.The fireproof curtain structure provided by the invention has the beneficial effects that the fireproof curtain structure can fall down to isolate a fire ground when is necessary, can effectively provide sufficient escape channels for actors too late to escape on the stage on the premise of quickly falling and ensuring an isolating effect, and has excellent isolating effect and escape effect.
Description
technical field [0001] The invention belongs to the field of stage technology, and in particular relates to a fireproof curtain structure. Background technique [0002] In the stage field, the safety fire curtain (also known as fire curtain, fire curtain, etc.) is a relatively special curtain, which is a protective curtain set between the audience hall and the stage, and at the entrance of the stage. It can also be said that It is a special door for safety and fire protection. When a fire accident occurs or each performance ends, the fire curtain falls, separating the stage and the auditorium into two fire prevention areas. However, due to the safety of the audience and other people outside the stage, the current fire curtain needs to be quickly isolated from the fire scene (mainly smoke isolation), so it needs to fall quickly, which also easily leads to some people who are far away from the fire curtain or run slowly. The actors could not escape the stage fire smoothly. ...
