Technical background
According to pertinent regulations, the smoke evacuation subregion in heavy construction such as market, arenas, garage etc. must not surpass 500m
2The flue gas that the fire initial stage is produced is controlled in certain scope, so that the personnel that evacuate rapidly in time enter with the personnel that put out a fire to save life and property.For this reason, fume-blocking vertical curtain or vertical wall are installed on the indoor top of building, and require to combine with ceiling decoration dexterously, and do not influence overall appearance, can be sagging rapidly when fire alarm takes place.Existing fume-blocking vertical curtain or vertical wall are varied, and turnover plate type, roll type are arranged, and have manually, also have automatically.Though can both play the effect of retaining cigarette, exist the deficiency that volume is big, span is little, the gap is big, automatic performance is low.It is that ZL96233805.2, notification number are that CN22678277Y, name are called the utility model patent of " full-automatic curtain-type smoke-proof pendant wall device " that Patent Office of the People's Republic of China announced the patent No. on November 19th, 1997, this device utilizes driven by motor swift rolling curtain or vertical wall, deadweight effect by counterweight falls curtain or vertical wall, adopt many covering devices to constitute the curtain or the vertical wall of large span, thereby exist curtain or vertical wall whereabouts stationarity is poor, gapped between curtain that many covers are formed or the vertical wall, influence retaining cigarette effect.
The purpose of this utility model be to provide a kind of meet the requirement of Building Fire Protection regulation, automaticity height, rational in infrastructure, volume is little, span is big, in light weight, good looking appearance, automatic fume-blocking vertical curtain easy for installation.
The content of innovation and creation
A kind of automatic fume-blocking vertical curtain that the utility model provides, comprise a strip box body, be installed in the fire-proof machine of box body one end, the chain wheel driving mechanism that is connected with motor or gear drive, one end is connected turning cylinder, upper end that the other end is contained in the other end of box body and is fixed on the turning cylinder or embedding is pressed in flameproof fabric in the turning cylinder groove with chain wheel driving mechanism or gear drive, it is characterized in that being equipped with at least a turning cylinder supporting seat, the counterweight that is connected with the flameproof fabric lower end vertical assembly of attaching most importance at box body middle part.At the box body middle part turning cylinder supporting seat being installed, is in order to reduce the amount of deflection of turning cylinder, to realize the purpose of the fume-blocking vertical curtain of manufacturing large span.Span is big more, and supporting seat is adorned manyly more.Span can be from several meters to tens meters.
Described a kind of automatic fume-blocking vertical curtain, the diameter of its turning cylinder is less, and the biserial double row self aligning ball bearings are equipped with the junction of chain wheel driving mechanism or the gear drive and the box body other end respectively in two ends.Adopt the less turning cylinder of diameter can reduce volume, the biserial double row self aligning ball bearings are installed at the turning cylinder two ends can automatic aligning.
Described a kind of automatic fume-blocking vertical curtain, its flameproof fabric is a monoblock, flameproof fabric is stitched into conduit with the end turnup that the assembly that heavily hangs down is connected.Flameproof fabric is made monoblock, and is seamless, and the retaining cigarette is effective.
Described a kind of automatic fume-blocking vertical curtain is connected with the steel wire more than two between its turning cylinder and the heavily vertical assembly, steel wire is sewn on the monoblock flameproof fabric, and the upper end is fixed on the turning cylinder or embedding is pressed in the turning cylinder groove, and the lower end connects the assembly that heavily hangs down.The purpose that steel wire is installed is after preventing that flameproof fabric from burning out, and the assembly that heavily hangs down falls the fire fighter that injures.
Described a kind of automatic fume-blocking vertical curtain, its heavy vertical assembly slightly is longer than round steel, the top end opening of flameproof fabric width by length and triangle button box and the trim that inwardly curls formed; Round steel is through in the conduit of flameproof fabric lower end, and steel wire is enclosed within the outside of conduit, and button box is buckled in the conduit outside that the flameproof fabric lower end is installed with round steel, and trim is buckled in the two ends of button box.The assembly that heavily hangs down that designs this structure is for the steady decline of fume-blocking vertical curtain is not swung, and can not hang over ceiling decoration during rising and sew on and draw bad holding court from behind a screen, and coordinates with ceiling decoration.
Described a kind of automatic fume-blocking vertical curtain, its supporting seat by one or two gripper shoe that is fixed on box body middle part sidewall, be contained on the gripper shoe at least one or support roller bearing or roller is formed; Be processed with the hole of a diameter on the gripper shoe greater than the turning cylinder diameter, and have one communicate with the hole opening, turning cylinder passes from the hole on the gripper shoe, supports the bottom that roller bearing or roller are contained in the hole of gripper shoe, and contacts with position below the turning cylinder center line.Supporting seat is installed at middle part at box body, and the turning cylinder middle part is supported, and the turning cylinder amount of deflection is reduced, thereby realize the purpose of little rotating shaft, large span.
Described a kind of automatic fume-blocking vertical curtain is equipped with gathering sill on the wall on the both sides of its flameproof fabric or the cylinder.Its role is to reduce the deviation angle of fume-blocking vertical curtain, cover the slit on flameproof fabric both sides, avoid smoke spillage.
Described a kind of automatic fume-blocking vertical curtain, its motor can positive and negatively rotate, by building fire-fighting center by control cabinet automatically control hold court from behind a screen sagging or reset, also can be on-the-spot sagging or reset by pressing manual knob control fume-blocking vertical curtain.
