The utility model overcomes current take that window firebreak device exists because of fire prevention glass fire behavior is relatively poor, it forms the shortcoming that the breach caused the intensity of a fire to stretch after water breaks to break under the short fire prevention glass high temperature that leads to of separation intensity of a fire time or meet during the fire control, has further strengthened the fire behavior who takes window firebreak device, and has used nimble convenience.
Description
Technical field
The utility model relates to a kind of firebreak device, is specifically related to a kind of high-performance fire-resistant glass device.
Background technology
At present, band form labeled door/window is usually used in escape way, can stop fire spreading when there is the condition of a fire within the regular hour, but at present with fire rated glass door/window all following two problems of ubiquity: 1, the fire resistance period of flame resistant glass is too short; 2, flame resistant glass is met water and can be burst when high temperature, can break, thus lose the function of fire-proof and thermal-insulation, cause the intensity of a fire to be spread by the breach formed after glass breakage when fire-fighting because water column impacts.
Utility model content
For the deficiencies in the prior art; the utility model aims to provide a kind of high-performance fire-resistant glass device; solution flame resistant glass fire resistance period is short, the defect of not water resistant impact, thus ensures that the fire-proof function of band form labeled door/window reaches the highest fire prevention time, to protect the security of the lives and property of user.
To achieve these goals, the utility model adopts following technical scheme:
A kind of high-performance fire-resistant glass device, comprises carrier and is installed on the fire-resisting glazing on carrier; Described fire-resisting glazing comprises at least one block of flame resistant glass and installs the framework of flame resistant glass; Described carrier is provided with the position, hole matched with described framework size, and described framework is fixedly assembled in position, described hole; Also be provided with at least one piece of fire resisting plate in described framework, described fire resisting plate is disposed adjacent with described flame resistant glass; At least one side place of described fire resisting plate is provided with the baffle plate consistent with the length of fire resisting plate and width, and described baffle plate is fixedly installed in described framework, and corresponding with fire resisting plate position; Described fire resisting plate is connected to described framework by easy fusible material; When described fire resisting plate is positioned at the left and right of flame resistant glass or below, described fire resisting plate is connected with at least one traction piece, and when fire resisting plate is positioned at the top of flame resistant glass, described fire resisting plate does not connect traction piece or connects at least one traction piece; One end of described traction piece is connected to described fire resisting plate, and the other end is then connected to the one end be connected with flame resistant glass in framework; The position of described flame resistant glass and fire resisting plate interlocks.
It should be noted that, carrier can select door, window or body of wall as required, after loading onto fire-resisting glazing, can become band form labeled door, window or body of wall.The fixing of fire resisting plate is carried out by easy fusible material, make when breaking out of fire, namely easy fusible material can automatically disconnect after temperature arrives fusing point, fire resisting plate is made to depart from the fixing of framework, thus in the effect lower slider of Action of Gravity Field or traction piece to the side place of flame resistant glass, safety and easily realize, avoid producing other unsafe factors in a fire.
It should be noted that further, the effect of traction piece is adopted then to be, no matter make the installation direction of device, top that fire resisting plate is positioned at flame resistant glass, below, left or right, fire resisting plate is after departing from framework and ensures to slide towards flame resistant glass direction, and finally slide into the side place of flame resistant glass, flame resistant glass is stopped and completely cuts off, even if make flame resistant glass after arrival fusing point breaks, the breach formed still has fire resisting plate close off, thus stops fire spreading.Therefore, by traction piece, device can select installation direction arbitrarily, uses flexibly.When described fire resisting plate is positioned at the top of flame resistant glass, traction piece can not be installed, utilize the potential energy of gravity to slide into the side place of flame resistant glass.Further, though described baffle plate be arranged so that fire resisting plate also can not form breach in framework after sliding into flame resistant glass side place, no matter at any time device totally-enclosed seamless state, ensure that the fireproof performance of device.
As a kind of preferred version, guide rail together with being respectively equipped with at least with corresponding position, described fire resisting plate position inside the both sides of described framework, the both side edges of described fire resisting plate is embedded in two side rails respectively, and can side place along slide to flame resistant glass under the effect of traction piece.The effect of guide rail is its guide effect when fire resisting plate slides, and prevents it from departing from origin-location.
Further, as a kind of preferred version, when arranging guide rail, described traction piece is positioned at described guide rail.Traction piece is arranged in guide rail, can the aesthetic property of intensifier.
As a kind of preferred version, described framework is divided at least two sashes by the body of rod, a sash is used for assembly flame resistant glass, and another one sash is then for assembly fire resisting plate and baffle plate, and the flame resistant glass that each sash is all installed with it or fire resisting plate match; Wherein, described flame resistant glass sealing assembly is in its place sash.
Further, as a kind of preferred version, described fire resisting plate is slightly longer than described flame resistant glass.Make fire resisting plate be longer than described flame resistant glass, can ensure that flame resistant glass blocks by fire resisting plate completely completely, prevent leaving space and make fire spreading.
As a kind of preferred version, described flame resistant glass adopts the special glass that can keep not breaking at least 5 minutes at high temperature 1000 DEG C.The performance of described flame resistant glass is better, then can stop that the time of fire spreading is longer, make device have the sufficient time to start, thus fireproof performance is better.
Further, as a kind of preferred version, described baffle plate adopts fire resisting plate.After fire resisting plate slides into the side place of flame resistant glass, baffle plate just replaces fire resisting plate, and in original position, it stops the effect of the intensity of a fire, therefore adopts fire resisting plate as baffle plate, is conducive to the fireproof performance strengthening whole device.
Further, as a kind of preferred version, described traction piece includes but not limited to one or more in extension spring, spring, belt tensioner and hydraulic means.
Method of fire protection based on above-mentioned high-performance fire-resistant glass device comprises the steps:
S1 is the reserved position, hole matched with framework size on carrier, and whole fire-resisting glazing is fixed assembly on the position, hole of carrier;
During S2 breaking out of fire, when temperature reaches the fusing point of described easy fusible material, described easy fusible material disconnects, and now fire resisting plate departs from the fixing of framework;
S3 is under the effect of traction piece, and described fire resisting plate slides towards the direction of flame resistant glass, finally slides into the side place of flame resistant glass, plays the effect of heat-insulating, fire-preventing in the lump with flame resistant glass.
It should be noted that, in step S1, can the installation direction of selecting arrangement according to actual needs, when selecting vertically to arrange, described fire resisting plate is positioned at above or below flame resistant glass, and when selecting horizontally set, described fire resisting plate is positioned at left or the right of flame resistant glass.
