Abstract

The utility model relates to a sealing material for a PVC plastic steel door and window, particularly a double glass sealing spacing strip which is a hollow strip with certain hardness and elasticity. The spacing strip is provided with a supporter, a supporting and clamping groove which can clamp double glass, and a sucking groove which can suck a glass plane, and can seal the space spaced and clamped between double glass plates so that leakage can not occur; therefore, dust and water vapour can not enter the double glass plastic steel door and window, and the heat insulation performance and the lighting degree of the door and window are improved. The utility model has the advantages of simple structure and easy manufacture and is an ideal auxiliary material for a PVC plastic and steel door and window.

Description

Double-glazing sealing strip

The utility model relates to the encapsulant of PVC plastic-steel door and window, especially a kind of pair of glass capsulation parting bead.It belongs to building technical field.

Along with the application of PVC plastic-steel door and window develops rapidly, two glass plastic-steel door and windows of cold district have impurity such as certain dust, gas to enter between the double-layer glass in actual applications, do not reach the national standard index of dustproof, insulation and daylighting degree.Here it is existing two glass parting beads structurally, the problem that exists on the material: parting bead and glass contact face adhere to imprecision.This parting bead is the line contact with contacting of glass-board surface, because the glass-board surface planeness differs, the line contact often is interrupted, and therefore causes gas leakage, leaks dirt, is not incubated.The collet of this parting bead, just carriage plays the glass section, and glass planar is not had any control action, thereby causes the close not tight result of envelope.

The purpose of this utility model is the sealing problem that will solve two glass parting beads.Design a kind of novel two glass parting beads, the two glass of PVC door and window are installed after, air permeability, rain leakage all reach the GB117931-89 standard; Air leakage performance (under the 10Pa)≤05m ³/ mh, rain leakage 〉=350Pa.

Task of the present utility model is that following technical scheme is finished: be developed into a kind of pair of glass capsulation parting bead.This parting bead adopts has that certain degree of hardness and elastic rubber-plastic composite material make.The down either side of the external sidewall of parting bead of its hollow is provided with two glass holder draw-in grooves of symmetry.This holder draw-in groove has the function of two aspects: one, it will distinguish the section that carriage plays the two sides glass-board surface; Two, it will distinguish firmly two sheet glass planes of clip, plays fixed pan glass.The notch of this holder draw-in groove, it is perpendicular to the width outline of the glass planar thickness less than glass plate.This holder draw-in groove also will have the elasticity width in certain elastic limit so that when the plug-in card glass-board surface, the elastic force that this notch edge can lean on cell body itself with notch edge sticker on glass-board surface.This holder draw-in groove gets final product fastening glass panels, outside in the salable again glass plate.On symmetry two lateral walls of hollow parting bead above the notch of this holder draw-in groove, also be provided with two symmetries, cross section is the sucking groove of circular arc.The trough rim of this sucking groove is along being on the same vertical plane.When this parting bead a pair of glass was installed, this parting bead was to be between two glass plates, and the symmetry two on the parting bead is sucked the trough rim of groove along just in time contacting with the glass plate plane of plug-in card on the holder draw-in groove.When again when glass-board surface is vertically exerted pressure, the trough rim of this groove so just makes the groove internal face of this groove and the contact area on glass plate plane increase gradually along stretching to the notch both sides, causes whole groove sucking at last on glass planar.All can there be card that this parting bead holds in the palm on four limits, upper and lower, left and right between two blocks of glass, sucks together like this, cause by in the cavity between four two glass plates that parting bead sealed, air is sealed up for safekeeping in this cavity, and can not let out, extraneous simultaneously air, dust, steam can not enter in this cavity yet, have reached good sealing effectiveness.

Further specify the cross sectional representation of embodiment of the present utility model: Fig. 1 below in conjunction with accompanying drawing for two glass parting beads.Fig. 1 has holder draw-in groove 1, sucks groove 2.Fig. 2 is that the two glass of PVC sash are installed sectional view.Fig. 2 has: sash frame 3, weather strip 4, glass plate 5, two glass capsulation parting beads 6, filler strip 7, glazing bead 8, block limit 9.

The erection sequence that this pair of glass capsulation parting bead is assemblied on the PVC plastic-steel door and window is: at first install inner seal bar 4 on sash frame 3, between four limit sections of two glass plates 5, adorn plug-in card more in addition four this pair glass capsulation parting beads 6 are arranged, the holder draw-in groove 1 of every parting bead, all ask clamping to touch on the plane, four limits of two glass plates, make two blocks of glass be linked into an integrated entity by four parting beads, the two bulk glass that then mounting board had parting bead, four filler strips 7 together with four parting bead outer bottoms are put in the sash frame 3, the glazing bead 8 of outside weather strip 4 will be housed at last, press to stick in the block limit 9 of sash frame 3.Two like this glass PVC plastic-steel door and windows just install.Because the holder card and the act of sucking of this pair glass parting bead make this pair glass PVC plastic-steel door and window reach excellent sealing effect.Through installation test: the air permeability of PVC plastic-steel door and window that this pair glass capsulation parting bead is installed is at 04m ³Under/the mh(10Pa), its rain leakage has all surpassed and has reached the index of GB117931-89 defined at 360Pa.

Claims (2)

1, a kind of pair of glass capsulation parting bead, it is characterized in that: in lateral wall down either side with certain degree of hardness and flexible hollow parting bead, be provided with two glass holder draw-in grooves (1) of symmetry, on symmetry two lateral walls of the hollow parting bead above this groove (1) notch, the cross section that is provided with two symmetries is the sucking groove (2) of circular arc.

2, according to described pair of glass capsulation parting bead of claim 1, it is characterized in that: described glass holder draw-in groove (1), its (1) notch is slightly less than the thickness of glass plate perpendicular to the width of glass planar, and has certain opening elasticity width.
