Description
Technical field
The utility model relates to a kind of hollow glass division bar, is that a kind of Passive low-energy building hollow glass warms up limit spacer bar specifically, also discloses the hollow glass prepared with this parting bead.
Background technology
The Chinese architecture glass issued on September 16th, 2014 according to Chinese architecture glass and industrial glass association and industrial glass association criterion, standard No. HB002-2014 " Passive low-energy building transparent part glass " is about the regulation of warm limit spacer bar, warm limit spacer bar adopts low thermal conductivity material to make, gas space interbed is separated to form for even support periphery, its comprehensive thermal conductivity coefficient Σ (d. λ)≤0.007W/K, comprehensive thermal conductivity coefficient is less, and the heat-proof quality of warm limit spacer bar is better.In formula, the thickness of d-hollow glass spaceband material, m; λ--the coefficient of hollow glass spaceband material, W/ (m.K).In " Passive low-energy building transparent part glass " standard No. HB002-2014, the common warm limit spacer bar arrangement of defined, is shown in Fig. 1, its comprehensive thermal conductivity coefficient Σ (d × λ)=2 (d1 × λ 1)+d2 × λ 2.Chinese utility model patent application CN103237949A " profiled spacer and the insulating glass unit with this profiled spacer ", disclose a kind of heat insulation glass profiled spacer (i.e. the parting bead of double layer glass), have the hollow profile body be made up of plastic material, hollow profile body forms hollow chamber by inwall, outer wall and the one the second sidewalls.Be provided with the first enhancement Layer outside the first side wall, be provided with the second enhancement Layer outside the second sidewall, outside outer wall, be provided with diffusion impervious layer.Two enhancement Layers and diffusion impervious layer are metal material, are combined in its face corresponding to hollow chamber preferably by adhesive.This parting bead, heat-proof quality is good, and Rigidity and strength is large.But this parting bead, by three metalwork composition diffusion barrier, for non-proliferation infiltration and intensity enhancing, complicated process of preparation, causes cost up, and be also not easy to mechanical automation and produce, production efficiency is lower.Chinese utility model patent " hollow glass compound parting bead and the hollow glass using this parting bead to prepare " (patent No. 201420364690.4) discloses a kind of hollow glass compound parting bead, this compound parting bead enhancement Layer is an entirety, preparation technology is simple, be convenient to mechanical automation preparation, production efficiency is high.This compound parting bead, enhancement Layer is with deformation take-up region, make metalwork and the working of plastics binding strength high life long, this compound parting bead can be made on bender during bending, the Liang Ge side corner of bending part forms the arc-shaped transitional surface of continuous and derivable, there will not be fracture, problem that bulge, two wrinkles etc. affect hollow glass quality; In addition in use, the deformation that deformation take-up region can also receive profile body to produce because expanding with heat and contract with cold, can effectively prevent profile body and metal shielding absciss layer.
But existing parting bead, its hollow profile body has been totally enclosed hollow chamber, the heat conduction factor of its outer wall itself, causes the overall effect of heat insulation of parting bead to decrease.
Utility model content
Technical problem to be solved in the utility model, is the defect overcoming prior art existence, proposes a kind of Passive low-energy building hollow glass and warms up limit spacer bar, effectively can reduce thermal conductivity coefficient U value.
The utility model Passive low-energy building hollow glass warms up limit spacer bar, is made up of hollow profile body and metal shielding; Hollow profile body is made up of inwall, outer wall and two sidewalls; Described metal shielding is overall plate, rolls over for U-shaped, and metal shielding U-shaped two bottom sides respectively has a groove outwardly, and this groove is that district is received in the deformation of metal shielding; Metal shielding is nested on hollow profile body outer wall and two side, and except district is received in deformation, the position that other positions of metal shielding are all corresponding with hollow profile body is bonded together; It is characterized in that: described hollow profile body outer wall has longitudinally through notch.
Further prioritization scheme is: the A/F of described longitudinal notch is 0.5mm-2mm.
Above-mentioned Passive low-energy building hollow glass warms up limit spacer bar for the preparation of hollow glass, comprise layer glass or two-layer above glass, described each layer glass is parallel to each other, between adjacent two layers glass, above-mentioned Passive low-energy building hollow glass is set along glass surrounding and warms up limit spacer bar, two sidewalls that described Passive low-energy building hollow glass warms up limit spacer bar respectively and bonding glass, Passive low-energy building hollow glass warms up limit spacer bar by the airtight space between adjacent two layers glass, described Passive low-energy building hollow glass warms up the confined space of inwall towards glass of limit spacer bar.
Be bonded together with hollow profile body outer wall bottom metal shielding U-shaped, make metal shielding can make up hollow profile body outer wall and disconnect and the intensity of loss.What is more important hollow profile body outer wall disconnects can block the heat transfer produced by outer wall between hollow profile body two sidewalls, makes the outer wall heat transfer disconnected by hollow profile body between hollow profile body two sidewalls be zero.Thus effectively reduce thermal conductivity coefficient U value.The comprehensive thermal conductivity coefficient Σ (d × λ) of warm limit spacer bar=(d1 × λ 1)+d2 × λ 2 of this spline structure.The warm limit spacer bar of the utility model and prior art two kinds of structures compares and can find out, for the warm limit spacer bar of the two kinds of structures adopting same materials and process to make, little d1 × the λ 1 of the comprehensive thermal conductivity coefficient of obvious warm limit spacer bar described in the utility model comprehensive thermal conductance coefficient ratio common warm limit spacer bar, its heat-proof quality is obviously better than common warm limit spacer bar heat-proof quality.
