Description
Technical Field
The utility model relates to a joint strip.
Background
The heat preservation, sound insulation, watertight and airtight performances of the PVC door and window are greatly improved. But PVC door and window and the joint strip that door and window sealed adopted belong to easily combustible material, have the potential safety hazard. Generally, sealing strips of PVC doors and windows are formed by extruding PVC, ethylene propylene diene monomer, TPV, TPE, TPR, SEBS, silica gel and other materials, the sealing strips of the doors and windows are nearest to a fire source in the process that the PVC doors and windows are subjected to fire, and the sealing fire-resistant strength of the doors and windows is far lower than that of a PVC door and window main body, so that the sealing strips of the doors and windows are firstly burnt, the sealing strips of the doors and windows deform or burn at high temperature, gaps between glass and the door and window main body are exposed, a channel for smoke channeling or fire channeling is formed, and finally the fire isolating function of the PVC doors and windows disappears. Even if the flame retardant effect of the sealing strip is improved by adding a flame retardant in the preparation process of the sealing strip, the high-temperature deformation cannot be avoided by the existing door and window sealing strip, and the deformation of the door and window sealing strip still can generate a gap between glass and a door and window main body after high temperature, so that a channel for smoke channeling or fire channeling is formed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the poor problem of current door and window sealing strip fire resistance, provide a fire-resistant joint strip.
The utility model discloses the cross-section of fire-resistant joint strip's main part is the rectangle, and fire-resistant joint strip's upper portion is the inclined plane, is provided with the card strip on fire-resistant joint strip's the narrower side, is close to upper portion inclined plane department in the fire-resistant joint strip and is provided with the through-hole that link up fire-resistant joint strip length direction, is provided with the incision that link up fire-resistant joint strip main part length direction on fire-resistant joint strip's the inclined plane, and the incision extends to inside the.
The utility model discloses principle and beneficial effect do:
the utility model discloses fire-resistant joint strip passes through the card strip to be installed in the draw-in groove of glazing bead, or sets up in the draw-in groove of door and window section bar. The existing sealing strips are mostly of closed structures, in the utility model, the inclined plane of the main body of the fire-resistant sealing rubber strip is provided with a notch which runs through the length direction of the main body, and the notch extends to the inside of the through hole to communicate the through hole with the outside; when no fire occurs, the sealing rubber strip has certain elasticity, and due to the compressing effect of the glass pressing strip or the door and window section bar, the sealing rubber strip is in a compressed state, so that the cut is sealed, and the inside of the through hole is sufficiently isolated from the outside.
The through hole is used for storing inorganic foaming materials, when a fire disaster happens, the sealing rubber strip is contracted after being radiated by a high-temperature heat source, the cut is opened at the moment, and the inorganic foaming materials stored in the through hole, such as water glass, are directly heated and generate a large amount of foaming products. The foaming product covers the gap between the glass and the section bar, and the gap is sealed or the sealing rubber strip and the section bar main body are covered, so that a fireproof and smoke-proof barrier is formed, and the fireproof time of the whole door window is prolonged.
Drawings
FIG. 1 is a schematic structural view of a fire-resistant sealant strip;
fig. 2 is a schematic view of the foaming products formed by the through holes 3 after the window sash profile provided with the fire-resistant sealing rubber strip meets fire.
The specific implementation mode is as follows:
the technical scheme of the utility model is not limited to the specific implementation modes listed below, and also comprises any reasonable combination between the specific implementation modes.
The first embodiment is as follows: the present embodiment is described with reference to fig. 1 to 2, a cross section of a main body 1 of the fire-resistant sealing rubber strip of the present embodiment is rectangular, an upper portion of the fire-resistant sealing rubber strip is an inclined surface, a clamping strip 2 is disposed on a narrow side of the fire-resistant sealing rubber strip, a through hole 3 penetrating through the fire-resistant sealing rubber strip in the length direction is disposed in the fire-resistant sealing rubber strip near the inclined surface of the upper portion, a notch 4 penetrating through the fire-resistant sealing rubber strip main body 1 in the length direction is disposed on the inclined surface of the fire-resistant sealing rubber strip.
Most of the existing sealing strips are of closed structures, in the embodiment, a cut 4 penetrating through the length direction of the main body 1 is arranged on the inclined surface of the main body 1 of the fireproof sealing rubber strip, and the cut 4 extends into the through hole 3 to enable the through hole 3 to be communicated with the outside; when no fire occurs, the sealing rubber strip has certain elasticity, and due to the compressing effect of the glass pressing strip or the door and window section bar, the sealing rubber strip is in a compressed state, so that the notch 5 is sealed, and the inside of the through hole 3 is sufficiently isolated from the outside. The through hole 3 is used for storing inorganic foaming materials, when a fire disaster happens, the sealing rubber strip is contracted after being radiated by a high-temperature heat source, the cut 4 is opened at the moment, and the inorganic foaming materials such as water glass stored in the through hole 3 are directly heated and generate a large amount of foaming products. The foaming product covers the gap between the glass and the section bar, and the gap is sealed or the sealing rubber strip and the section bar main body are covered, so that a fireproof and smoke-proof barrier is formed, and the fireproof time of the whole door window is prolonged.
FIG. 1 is a schematic structural view of a fire-resistant sealant strip; fig. 2 is a schematic view of the foaming products formed by the through holes 3 after the window sash profile provided with the fire-resistant sealing rubber strip meets fire. In fig. 2, a is a foaming product generated after the fire of the fire-resistant sealing rubber strip at the outdoor side of the window sash profile, b is a foaming product generated after the fire of the fire-resistant sealing rubber strip at the indoor side of the window sash profile, c is an outer side grid stop part of the window sash profile, d is a glass bead, and e is fireproof glass; as can be seen from fig. 2, the cut 4 is opened upon fire, and the inorganic foaming material (e.g., water glass) stored in the through-hole 3 is heated and generates a large amount of foamed product. The foaming product covers the gap between the glass and the section bar, the gap is sealed or the sealing rubber strip and the section bar main body are covered, the fireproof and smoke-proof barrier effect is achieved, and the fireproof time of the whole door window is prolonged.
For example, water glass can be used as the inorganic foaming material, and the density of the water glass is 1.4g/cm3The modulus (molar ratio of silicon oxide to alkali metal oxide) was 3.2; the commercially available water glass is used as an adhesive, after the liquid water glass is filled in the through hole 3, the water glass is kept stand at normal temperature to be solidified, the liquid water glass can be solidified in a drying mode, more free water still exists in the solidified water glass, the solidified water glass is softened and simultaneously vaporized when the ambient temperature reaches 200 ℃, porous foaming water glass is formed, the volume of the hardened water glass before and after foaming can be increased by 5-20 times, and the obtained foaming material is made of Na2SiO3Belongs to a non-combustible material and has a fireproof function. The liquid water glass is sodium water glass or potassium water glass.
