Abstract

The utility model relates to an inorganic combined type fireproof rolling shutter. A rolling slat is divided into an inner rolling slat and an outer rolling slat. The upper and the lower ends of the rolling slat are connected with an upper connecting plate and a base plate. A shutter core is a fireproof and thermal insulation shutter core with a continuous integrated structure, and is clamped between the inner and the outer rolling slats. The inner rolling slat can automatically extend and shrink at the time of twisting, and is formed by buckling and connecting strip-shaped rolling slats. Line speed difference produced when the inner and the outer rolling slats are twisted can be eliminated, causing the twisting to be more convenient and the rigidity to meet a fireproof requirement. The integrated continuous fireproof shutter core can cause a fire receiving rolling slat and a fire deviating rolling slat to be mutually isolated. The utility model can have good performance of radiation heat isolation, can be used without a water curtain, has high automaticity, can be linked with a fire-fighting center for control, and can be used for various buildings.

Description

Inorganic combined type fire curtain

The utility model relates to the rolling door that a kind of building is used, particularly a kind of rolling door with fire prevention, Smoke prevention effect.

Existing fire prevention, Smoke prevention rolling door are divided into three major types: one, individual layer steel fire curtain; Two, combined type steel fire curtain; Three, inorganic fireproof rolling curtain.Generally comprise base, guide rail, curtain plate, bearing support combination, the combination of lacing film box, casing, spool, chain gear transmission, driving end supporting plate, door-rolling machine, electric control box, closing-code, button.Because fire-proof heat-insulating material is contained in the curtain plate, makes the composite fireproof insulating curtain become interrupted structure, work can not be satisfied with the technical requirements of fire prevention curtain wall, fire prevention partition after the radiant heat poor performance, can only be used with water curtain; And inorganic fireproof rolling curtain is fine every the radiant heat effect, but wind pressure resistant strength is poor, and the hot gas wave when big fire takes place is easy to make the curtain plate body to deviate from guide rail and lose fire-proof function, simultaneously, adopts double track structure, and moulding is too fat to move, and outward appearance is not attractive in appearance, and is inharmonious with modern architecture.End, existing bar shaped curtain plate both sides is that circular clasp is interlockingly connected, and it is poor to be easy to generate linear speed when curling.

The purpose of this utility model is a kind of improved steel compound fire-retardant rolling curtain of design, strengthens fireproof performance, can use under the condition that the cancellation water curtain cools off, and each performance indications can reach the fire prevention curtain wall, fire prevention cuts off the technical requirements of using, and makes curling convenient.

The technical solution of the utility model is:

Inorganic combined type fire curtain, comprise base, guide rail, curtain plate, bearing support combination, the combination of lacing film box, casing, spool, chain gear transmission, driving end supporting plate, door-rolling machine, electric control box, closing-code, button, it is characterized in that: curtain plate and outer curtain plate in curtain plate divides, its upper and lower end is connected with bed plate with upper junction plate, the curtain core is continuous integrally-built fireproof heat insulation curtain core, is clipped between the inside and outside curtain plate.

Curtain plate is fastened and connected by the bar shaped curtain plate in above-mentioned, bar shaped curtain plate middle bent, Yi Bian be curled into circular clasp, another side bends to oval bar shaped clasp, and circular clasp end fastens mutually, and oval bar shaped clasp end fastens mutually, and buckling end is automatically retractable when curling.

Using method of the present utility model is: when fire takes place, cigarette sense probe is at first reported to the police, send fire signal, electric control box and control centre connect net, start the door-rolling machine running, fire curtain is delayed time and is continued to drop to fastening position after 1-3 minute from the upper overhead 1.5 meters time-outs that drop to, when using hand push button, operator precedence is in automatic control.Because inside and outside metal curtain plate is isolated by the fireproof heat insulation curtain core of continuous one, play good during work every photothermy.

The utility model has the advantages that: fireproof heat insulation curtain core is the whole continuously inorganic fire insulating curtain core of a slice, makes do not contacted mutually with the fiery face curtains plate of the back of the body by fiery face curtains plate, isolated by heat-barrier material comprehensively, and the temperature difference is big during work, every the radiation good in thermal property; Interior curtain plate is scalable fastening structure, and it is poor to have eliminated the linear speed that produces when inside and outside curtain plate curls; Guide rail adopts the single track operation, makes to curl conveniently, and rigidity can satisfy fire protection requirement; Can cancel water curtain and use, the automaticity height can be controlled with the interlock of fire-fighting center, can satisfy the use of various buildings.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is Fig. 2 A-A sectional drawing.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is the profile of the inside and outside curtain plate shape of the utility model.

As shown in Figure 1, 2, inorganic combined type fire curtain comprises base 1, guide rail 2, curtain plate, bearing support combination 4, lacing film box combination 5, casing 6, spool 7, chain gear transmission 8, driving end supporting plate 9, door-rolling machine 10, electric control box 11, closing-code 12, button 13.It is characterized in that: curtain plate 16 and outer curtain plate 3 in curtain plate divides, its upper and lower end is connected with bed plate 1 with upper junction plate 15, and curtain core 14 is the heat insulation felt rugs of continuous integrally-built inorganic fire, is clipped between inside and outside curtain plate 16 and 3.Interior curtain plate 16 as shown in Figure 3, being fastened and connected by the bar shaped curtain plate forms bar shaped curtain plate middle bent, be curled into circular clasp 17 on one side, another side bends to oval bar shaped clasp 18, and circular clasp end fastens mutually, oval bar shaped clasp end fastens mutually, and buckling end is automatically retractable when curling.Guide rail 2 adopts the single track form.
