Fireproofing machinery folding device opened by deadweight

Abstract

The invention discloses a building fire-proof mechanical open-close device which is opened by the dead weight. Two fixed roofs are tilted on fixed struts at two sides respectively, wherein each fixedroof is provided a group of V-shaped linear guide rails the upper sections of which have smaller frictional coefficient than the lower sections along two sides of an inclined plane respectively, the two groups of the V-shaped linear guide rails are connected with a respective sliding roof respectively, the lower bottom surfaces of the upper ends of the two sliding roofs are connected with one endof each of connecting plates respectively, the other ends of the two connecting plates are connected through a connecting device, and the tops of the two sliding roofs are crossed with each other. When fire happens, the open-close device is opened under the action of a driving device to cause smog close to the ground to go up and be discharged outside a building, thereby reducing the effect of thesmog on people in the building, simultaneously creating time and conditions for firefighters to save people and put out the fire. At the same time, the open-close device also has the functions of ventilation and lighting, resisting wind and snow, and preventing rainwater and draining to the roofs. The open-close device has high reliability and the opening time is not more than 45 seconds withoutelectric and mechanical drive sources and the like.

Description

technical field [0001] The invention relates to a mechanical opening and closing device capable of realizing the fire prevention function on a large building. Background technique [0002] A mechanical opening and closing device for building fire prevention belongs to a kind of opening and closing roof. Opening and closing roof is a structural form in which part or all of the roof can be moved or opened and closed. Its realization is to divide a complete roof structure into several movable and fixed units according to certain rules, so that the movable units It can move according to a certain trajectory to achieve the purpose of roof opening and closing. In our country, although the opening and closing roofs of several gymnasiums have been built, generally speaking, the opening and closing roofs are still in their infancy, and there are no national standards or local design specifications at present. Although there are some similarities between the building fire protection...
