Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Referring to fig. 1-4, a single pair of guide rail inorganic cloth fireproof curtain comprises a double-layer curtain surface 3 and a scroll 4, wherein the inner side of the double-layer curtain surface 3 is fixedly connected with a plurality of horizontal square pipes which are vertically and alternately distributed; the square tube vertically passes through and is fixedly connected with a plurality of steel wire ropes 5 at intervals, and the steel wire ropes 5 are wound on the scroll 4; two ends of the square tube are limited in a pair of vertical guide rails 1.
In this embodiment, see fig. 1, the double-layered curtain 3 is fixedly connected to the square tube by means of a horizontal bead 2.
In this embodiment, the square tube has a width equal to the outer diameter of the reel 4, and the reel 4 is also retained in the pair of guide rails 1. The figures do not show this in detail.
In this embodiment, the square tube has a cross-sectional side length of less than 100mm.
It is further preferred that the square tube has a cross-sectional side length of 50mm, i.e. the spacing between the double-layer curtain surfaces. In the prior art, a mode that a single-layer curtain face faces a pair of guide rails is adopted, the distance between the double-layer curtain faces is 300mm-450mm, and obviously, the distance between the double-layer curtain faces is greatly reduced in the scheme of the embodiment.
In this example, the square tube has a sheet thickness of 2mm.
In this embodiment, see fig. 2 (a), when the double layer curtain 3 is retracted upward, the double layer curtain 3 is spread out to the opposite sides of the steel pipe.
In this embodiment, referring to fig. 2 (b) and 4, the spacing between vertically adjacent steel pipes is 500mm.
In this embodiment, see fig. 1, a reel 6 is also included, coaxially arranged on one side of the reel 4, which reel rotates the reel 4.
In this embodiment, with continued reference to fig. 1, a control box 7 is also included, the control box 7 being electrically connected to the reel 6.
The utility model adopts a transmission mode that the rolling machine drives the rolling shaft to rotate through a chain, wherein the motor adopts a special rolling door machine which is accurate in positioning, safe in opening and closing, and high in stability and reliability. The scroll is formed by integrally welding high-quality round steel pipes, and has good strength and rigidity. The support plate is formed by bending a high-quality steel plate with the thickness of 6mm, so that stable installation is ensured. The curtain surface is formed by compounding a plurality of inorganic refractory materials.
On the front elevation, galvanized square pipes of 50×50×2mm are arranged at intervals of about 500mm in the lateral direction, and the galvanized square pipes are taken as a whole frame. The double-layer curtain surface is fastened on the square tube through the pressing strip. The steel wire rope with phi 4 longitudinally passes through the round hole on the square tube, the top end is fixed on the reel, and the bottom end is fixed on the bottom beam. The steel wire rope lifts the ground beam through the rotation of the reel, and extrudes the curtain surfaces on two sides to fold and rise, so that the curtain surfaces are opened; the scroll rotates reversely, so that the curtain surface is put down, and the curtain surface is closed. The two ends of the square tube are arranged in the guide rail, and the curtain surface can play a role in guiding when in opening and closing operation. When the curtain surface is in a closed state, the square pipe is effectively overlapped with the guide rail, so that the whole curtain surface has certain strength, can bear the pressure difference generated in a fire disaster, ensures the whole curtain surface to be stable, and effectively plays a role in preventing flame from spreading.
The control system comprises a control box, a button box, a wire and the like, and the curtain surface is opened and closed by driving the rolling door machine to rotate forwards and reversely.
After the scheme of the embodiment is adopted, the width of the guide rail can be controlled within 100mm while the fire resistance of the special-grade fireproof roller shutter is met, the occupied space is greatly reduced, and the closing-in of decoration engineering is facilitated.
The foregoing is a preferred embodiment of the present utility model, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed utility model.
