Abstract
The utility model discloses a strenghthened type graphite fire prevention strip belongs to fire prevention strip technical field, including fire prevention strip body and cooperation cladding in this external metal mesh of fire prevention strip, just the extexine of fire prevention strip body inlay in in the mesh of metal mesh. The utility model discloses a cladding metal mesh outside fire prevention strip body, the extexine of a body of will preventing fires simultaneously inlays in the mesh of metal mesh, makes fire prevention strip body and metal mesh connect into a whole to having improved the bulk strength of fire prevention strip, having avoided fire prevention strip breaking occur, improved the controllability of fire prevention strip, the metal mesh that adopts simultaneously is network structure, can not obstruct fire prevention strip body and expand under high temperature.
Description
Technical field
The utility model relates to fireproof strip field, is specifically related to a kind of reinforced graphite fireproof strip.
Background technology
Fireproof strip is mainly used between the door leaf and doorframe, door leaf and door leaf of steel casement door or timber, fireproof strip automatic expansion in the time of breaking out of fire, shutoff crack between a door and its frame gap, intercept the circulation of air between inside and outside two spaces of door, effectively prevented the early stage dense smoke of fire, the harm to human body of toxic gas and hot gas is also controlled fire spreading.
Prepared by the general material with expanded by heating that adopts of current fireproof strip, the general expanding material coefficient of expansion is lower, sealing is poor, and expansible graphite has the higher coefficient of expansion, and high temperature resistant, sealing is strong, but general graphite fireproof strip is because intensity is poor, easy fracture, thereby cause poor controllability, be not easy to install.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical deficiency, proposes a kind of reinforced graphite fireproof strip, to improve the intensity of graphite fireproof strip, solves the poor controllability that in prior art, graphite fireproof strip intensity is low, easy fracture causes, difficult technical problem of installing.
For reaching above-mentioned technical purpose, the technical solution of the utility model provides a kind of reinforced graphite fireproof strip, comprise fireproof strip body and coordinate being coated on this external wire netting of described fireproof strip, and the extexine of described fireproof strip body is embedded in the mesh of described wire netting.
Preferably, described fireproof strip body and wire netting are interference fit, and the extexine of described fireproof strip body is concordant with the outer surface of wire netting from projecting in the mesh of described wire netting.
Preferably, rounded, oval, the rectangle of the cross section of described fireproof strip body.
Preferably, the cross section of described fireproof strip body is rectangle, and the top layer up and down of described fireproof strip body is embedded in the mesh of described wire netting.
Preferably, described wire netting is a both ends open and the cylindrical shell that matches with described fireproof strip body.
Preferably, the metal wire knitted that described wire netting is 0.1 ~ 0.5mm by external diameter forms.
Preferably, described fireproof strip body is cylindric, and external diameter is 10 ~ 20mm.
Preferably, described fireproof strip body is rectangular-shaped, and width, thickness are respectively 15 ~ 50mm, 1 ~ 5mm.
Compared with prior art, the utility model passes through at fireproof strip body outer cladding one wire netting, the extexine of fireproof strip body is embedded in the mesh of wire netting simultaneously, make fireproof strip body and wire netting connect into an entirety, thereby improve the bulk strength of fireproof strip, avoided fireproof strip to rupture, improved the controllability of fireproof strip, the wire netting simultaneously adopting is network structure, can not hinder fireproof strip body and at high temperature expand.
Brief description of the drawings
Fig. 1 be reinforced graphite fireproof strip of the present utility model a kind of embodiment analyse and observe syndeton schematic diagram;
Fig. 2 be reinforced graphite fireproof strip of the present utility model another kind of embodiment analyse and observe syndeton schematic diagram.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, embodiment of the present utility model provides a kind of reinforced graphite fireproof strip, comprise fireproof strip body 1 and coordinate the wire netting 2 being coated on outside described fireproof strip body 1, and the extexine of described fireproof strip body 1 is embedded in the mesh of described wire netting 2.
The present embodiment passes through at fireproof strip body 1 outer cladding one wire netting 2, the extexine of fireproof strip body 1 is embedded in the mesh of wire netting 2 simultaneously, make fireproof strip body 1 and wire netting 2 connect into an entirety, thereby improve the bulk strength of fireproof strip, avoid fireproof strip to rupture, improved the controllability of fireproof strip, the wire netting 2 simultaneously adopting is network structure, can not hinder fireproof strip body 1 and at high temperature expand.
While specifically setting, fireproof strip body 1 and wire netting 2 can be set to interference fit, and the extexine of described fireproof strip body 1 is concordant with the outer surface of wire netting 2 from projecting in the mesh of described wire netting 2, thereby make fireproof strip outer surface still form even surface, avoid the uneven sealing that causes of outer surface because of wire netting 2 poor and damage a door body while installing.
The fireproof strip of the present embodiment can be set to the shape needing as required, general preferred fireproof strip cross section is set to circle, ellipse, rectangle, be also rounded, oval, the rectangle of cross section of fireproof strip body 1, the cylindrical shell that 2 of wire nettings are set to a both ends open and match with described fireproof strip body 1 simultaneously. The present embodiment preferably adopts two kinds of embodiments: as shown in Figure 1, one is that fireproof strip body 1 cross section is for circular, be that fireproof strip body 1 is for cylindric, wire netting 2 is coated on the outer surface of fireproof strip body 1, and the extexine of fireproof strip body 1 is embedded in the mesh of wire netting 2, and concordant with the outer surface of wire netting 2 from projecting in mesh, be that the outer surface of fireproof strip body 1 and the appearance aspect of wire netting 2 are on same disc, and the external diameter of fireproof strip body 1 is generally 10 ~ 20mm, preferably adopt 15mm; As shown in Figure 2, another kind is that the cross section of fireproof strip body 1 is rectangle, be that fireproof strip body 1 is, while fire prevention as sealing due to rectangular-shaped fireproof strip, be only that its upper and lower surface works, therefore the top layer up and down of fireproof strip body 1 is embedded in the mesh of described wire netting 2, and the rectangular-shaped general width of fireproof strip body 1 is that 15 ~ 50mm, thickness are 1 ~ 5mm, due to thinner thickness, therefore be difficult for being embedded in wire netting 2 on thickness side, also be unnecessarily embedded in wire netting 2, therefore, the present embodiment thickness side is not embedded in wire netting 2.
For the ease of practical operation, the wire netting 2 of the present embodiment is a both ends open and the cylindrical shell that matches with described fireproof strip body 1, and this cylinder-shaped wire netting 2 preferably adopts wire 21 braidings that external diameter is 0.1 ~ 0.5mm to form, thereby can in making fireproof strip body 1, work out outside wire netting 2 is coated on, be conducive to enhance productivity.
The above detailed description of the invention of the present utility model, does not form the restriction to the utility model protection domain. Any various other corresponding changes and distortion of making according to technical conceive of the present utility model, all should be included in the protection domain of the utility model claim.
