Description
(1) technical field
The present invention relates to a kind of building external envelope structure, especially relate to a kind of apparent frame glass curtain wall of building external envelope structure.Belong to the building structure technology field.
(2) background technology
Curtain wall, door and window are the important component parts of building external envelope structure, also are the most active, the sensitive part of building interchange of heat, conduction of heat, and the loss of heat loss is about 5 to 6 times of traditional body of wall.The energy consumption of curtain wall, door and window accounts for about 40% of whole building energy consumption, this shows that the energy-saving design of curtain wall, door and window is even more important.How find an equalization point improving between heat-insulating property that space enclosing structure particularly shows frame glass curtain wall and the reduction construction costs, this is the problem that each curtain wall designer must face.Showed the energy-saving design of frame glass curtain wall, aluminium extruded sections adopts the heat-insulating bridge-cut-off section bar in the past, promptly adopts PA66GF25 (glass fiber-reinforced nylon) heat insulating strip or adopts PUR (polyurethane) material heat insulating strip section bar, and its structure as shown in Figure 1.As seen from Figure 1, this structural screws only connects heat-barrier material, load is passed to aluminium extruded sections by heat-barrier material, the ability of heat-barrier material bearing load is eager to excel, and therefore need select the strong PA66GF25 of heat-insulating capability (glass fiber-reinforced nylon) heat insulating strip for use or adopt PUR (polyurethane) material heat insulating strip.And PA66GF25 (glass fiber-reinforced nylon) heat insulating strip or employing PUR (polyurethane) material heat insulating strip material cost are higher.
Interrelated data shows, as far back as last century, Europe is exactly the PVC that adopts when manufacturing " disconnected heat " aluminium extruded sections, found afterwards that PVC material physical property, especially coefficient of thermal expansion were low than aluminium alloys big (coefficient of thermal expansion is that 5～18 * 10-5 ℃ of its thermal stress will exceed 60%～500%) and heat distortion temperature, the cold bridge built-up section will produce distortion or relatively move under the stress situation, even come off, can not satisfy the quality requirement of heat insulation window, by research, the close new materials of index such as coefficient of thermal expansion, intensity have been found with aluminium extruded sections.Just produce PA66GF25 (glass fiber-reinforced nylon) heat insulating strip or adopted PUR (polyurethane) material heat insulating strip.But comparing with PA66GF25 and PUR, PVC has bright price advantage.The performance and price of PVC and PA66GF25 and PUR compares: PVC tensile strength is low than aluminium alloys, and softening point is low, and acid and alkali-resistance power is extremely strong, and chemical stability is good, and material thermal conductivity is 0.16W/ (mK) approximately.Therefore, cheap PVC can be used for non-structural heat-insulation material.PA66GF25 and PUR heat-barrier material, these two kinds of material thermal conductivities be less than 0.3W/ (mK), heat distortion temperature (℃) 〉=220, thermal conductivity (coefficient of thermal conductivity) (W/mK) 0.2～0.35, linear expansion coeffcient (K-1) (2.0～3.5) * 10
-5, impact strength (non-notch) (kJ/m
2) 〉=30, elongation at break (%) 〉=3.5, UV resistant and heat aging performance etc. more meet the performance and the machining feature of aluminium alloy extrusions, meet in the JG/T174-2005 of the Ministry of Construction standard the requirement on the PA66GF25 heat insulating strip performance.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide the PVC heat insulating strip that a kind of heat-insulating capability is strong, cost is lower again to show the frame glass curtain wall structure.
The object of the present invention is achieved like this: a kind of PVC heat insulating strip shows the frame glass curtain wall structure, comprise column and hollow glass, described column comprises aluminium extruded sections, the aluminium extruded sections inner cover plate, aluminium extruded sections outer cover plate and screw, described aluminium extruded sections inner cover plate lid places on the aluminium extruded sections, aluminium extruded sections outer cover plate lid places outside the aluminium extruded sections inner cover plate, hollow glass is embedded between aluminium extruded sections and the aluminium extruded sections inner cover plate by sealing joint strip, be equipped with a PVC heat insulating strip between described aluminium extruded sections and the aluminium extruded sections inner cover plate, and with screw with described aluminium extruded sections inner cover plate, PVC heat insulating strip and the direct cross-under of aluminium extruded sections three are fixed.
The invention has the beneficial effects as follows:
The direct cross-under aluminium extruded sections of structural screws of the present invention inner cover plate, heat-barrier material and aluminium extruded sections, load directly is passed to aluminium extruded sections, and the aluminium extruded sections heat-insulating capability is strong.The PVC heat insulating strip uses as location, heat insulating function, be not subjected to longitudinal shear, horizontal twisting force, therefore can not produce distortion or relatively move, from the textural quality influence of just avoiding coefficient of thermal expansion and heat distortion temperature to heat insulation window, more can not come off, damage.Because the PVC material price is cheap, aging under sealing, unglazed environment, have higher safety, reliability.Therefore, under the prerequisite that can satisfy instructions for use and national building energy-saving standard, the present invention uses the PVC heat-barrier material to have the higher ratio of performance to price.

(5) specific embodiment
Referring to Fig. 2, Fig. 2 shows frame glass curtain wall structural upright sectional view for PVC heat insulating strip of the present invention.As seen from Figure 2, PVC heat insulating strip of the present invention shows the frame glass curtain wall structure, comprise column and hollow glass 3, described column comprises aluminium extruded sections 1, PVC heat insulating strip 2, aluminium extruded sections inner cover plate 4, aluminium extruded sections outer cover plate 5 and screw 6, described aluminium extruded sections inner cover plate 4 lids place on the aluminium extruded sections 1, aluminium extruded sections outer cover plate 5 lids place outside the aluminium extruded sections inner cover plate 4, hollow glass 3 is embedded between aluminium extruded sections 1 and the aluminium extruded sections inner cover plate 4 by sealing joint strip 7, PVC heat insulating strip 2 is embedded between aluminium extruded sections 1 and the aluminium extruded sections inner cover plate 4, and with screw 6 with described aluminium extruded sections inner cover plate 4, PVC heat insulating strip 2 and the direct cross-under of aluminium extruded sections 1 three are fixed.Select the sealing joint strip of suitable size, make between PVC heat insulating strip and the aluminium extruded sections inner cover plate and leave certain interval (contacting substantially), eliminate the influence of thermal deformation.
Referring to Fig. 3 and Fig. 4, Fig. 3 is a PVC heat insulating strip Facad structure schematic diagram of the present invention.Fig. 4 is a PVC heat insulating strip profile of the present invention.By Fig. 3 and Fig. 4 as can be seen, PVC heat insulating strip 2 of the present invention is designed to elongated, owing to connect reasonable in design, overcome the influence of temperature action, its heat-blocking action and PA66GF25 and PUR heat insulating strip basically identical, only the PVC heat insulating strip is not subjected to longitudinal shear, horizontal twisting force, only plays the role of positioning on structure stress.The PVC heat insulating strip was pressed the tie point spacing and can be installed earlier in the workshop before wall on curtain-wall stand-column, the crossbeam is installed, be installed in construction with other built-up sectional material and go up indistinction.
