Description

PVC heat insulation structure shows frame glass curtain wall

(1) technical field

The utility model relates to a kind of building external envelope structure, especially relates 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 purpose of this utility model is to overcome above-mentioned deficiency, provides the PVC heat insulation structure that a kind of heat-insulating capability is strong, cost is lower again to show frame glass curtain wall.

The purpose of this utility model is achieved in that a kind of PVC heat insulation structure shows frame glass curtain wall, 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 insulation between described aluminium extruded sections and the aluminium extruded sections inner cover plate, be provided with an elongated slot in PVC heat insulation middle part, described PVC heat insulation links to each other with aluminium extruded sections with the dovetail connected mode, and with screw with described aluminium extruded sections inner cover plate, PVC heat insulation and the direct cross-under of aluminium extruded sections three are fixed.

The beneficial effects of the utility model are:

The direct cross-under aluminium extruded sections of the utility model structural screws 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 insulation 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 utility model uses the PVC heat-barrier material to have the higher ratio of performance to price.
