Abstract

The present invention provides a kind of fire-proof expansion seal strips, the cavity surrounded by the U-shaped inner wall and U-shaped outer wall and inner and outer wall of setting, expansion core material is wherein equipped in cavity, when fire occurs, temperature increases expansion core material expanded by heating, the core material of expansion fills up the gap of sealing strip, and door or window are sealed to the sprawling for preventing fire and cigarette.It prevents fire from spreading and being diffused into another room from a room, fire damage is made to expand.

Description

A kind of fire-proof expansion seal strip

Technical field

The invention belongs to building material field more particularly to a kind of fire-proof expansion seal strips.

Background technology

Currently, the raising with people to the anti-consciousness of fire, also can increasingly pay attention to fire safety problem, still in daily life Our common windows and the certain gaps Men Douyou, fire spread in order to prevent, it is miscellaneous that there have been various specifications Sealing strip, to prevent the sprawling of open fire and flue gas, but these sealing strips will be burnt out in the condition of high temperature in sealing strip, cannot Play the role of obstructing pyrotechnics well, lowers unnecessary loss.

Invention content

In order to solve the problems, such as that door and window seals at high temperature, the present invention provides a kind of fire-proof expansion seal strip, structure, Including：

Expansion core material is equipped in the cavity of inner wall, outer wall and inner wall, outer wall, wherein cavity；The inner wall, outer wall are U-shaped, The outer wall is equipped with V-groove.

Further, the inside of the inner wall is equipped with anti-skidding back-off.

Further, the anti-skidding back-off is symmetrically arranged at for 4 on inner wall.

Further, the material of the inner wall is silica gel.

Further, the material of the outer wall is PVC.

Further, the cavity is rectangle, inside fills up expansion core material.

Further, the thickness of the outer wall is the half of inner wall thickness.

The beneficial effects of the invention are as follows：The present invention provides a kind of fire-proof expansion seal strips, including：U-shaped inner wall and U-shaped outer Expansion core material is equipped in the cavity that wall and inner and outer wall surround, wherein cavity, when fire occurs, temperature increases expansion core material The core material of expanded by heating, expansion fills up the gap of sealing strip, and door or window are sealed to the sprawling for preventing fire and cigarette.Prevent fire Calamity spreads and is diffused into another room from a room, and fire damage is made to expand, to make between each fire compartment mutually not It influences, by the control of fire within the fire compartment of burning things which may cause a fire disaster, so that the loss of building fire is reduced to minimum.

Description of the drawings

Fig. 1 is a kind of schematic cross-section of fire-proof expansion seal strip.

Specific implementation mode

To facilitate the understanding of the present invention, below with reference to relevant drawings to invention is more fully described.In attached drawing Give the preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to herein Described embodiment.Keep the understanding to the disclosure more saturating on the contrary, purpose of providing these embodiments is It is thorough comprehensive.

Invention is further described in detail below in conjunction with the accompanying drawings and the specific embodiments.

It is a kind of schematic cross-section of fire-proof expansion seal strip referring to Fig. 1, Fig. 1, including：

It is equipped with expansion core material 4 in the cavity 3 of inner wall 1, outer wall 2 and inner wall 1, outer wall 2, wherein cavity 3, it is the inner wall 1, outer Wall 2 is U-shaped, its volume expansion ratio under the action of flame of core material 4 is expanded when fire occurs and is more than 3, fire endurance one Grade (is more than 240min), is suitable for building structure gap, and the outer wall is equipped with V-groove 21.

Specifically, the inside of the inner wall 1 is equipped with anti-skidding back-off 11, the anti-skidding back-off 11 is symmetrically arranged at interior for 4 Wall 1, is fixed on convenient for expanding sealing strips on glass door and window.

Specifically, the material of the inner wall 1 is silica gel.

Specifically, the material of the outer wall 2 is PVC.

Specifically, the cavity 3 is rectangle, expansion core material 4 is inside filled up.

Specifically, the thickness of the outer wall 2 be inner wall thickness half, when fire occurs temperature increase expand core material by It thermally expands, outer wall 2 is burst, gap is filled up by the core material of expansion.

The present invention provides a kind of fire-proof expansion seal strips, pass through the U-shaped inner wall of setting and U-shaped outer wall and inner and outer wall Expansion core material is equipped in the cavity surrounded, wherein cavity, when fire occurs, temperature increases expansion core material expanded by heating, expansion Core material the gap of sealing strip is filled up, door or window are sealed prevent fire and cigarette sprawling, prevent fire from a room Another room is spread and be diffused into, fire damage is made to expand.

Relationship described in attached drawing is used to only for illustration, should not be understood as the limitation to this patent, it is clear that this The above embodiment is merely an example for clearly illustrating the present invention for invention, and is not to embodiments of the present invention Restriction.For those of ordinary skill in the art, other not similar shapes can also be made on the basis of the above description The variation or variation of formula.There is no necessity and possibility to exhaust all the enbodiments.It is all in the spirit and principles in the present invention Within made by all any modification, equivalent and improvement etc., should all be included in the scope of protection of the claims of the present invention.
