Description
Technical field
The present invention relates to a kind of curtain wall Reconstruction in field is the construction technology of hollow glass curtain wall, belongs to energy-saving building technology field.
Background technology
In China, building energy consumption accounts for the ratio of 30% of the energy consumption of the whole society, consume energy with industry, traffic consumes energy and claim China three large " energy consumption rich and influential family ", and along with the increase of living space, people are to the progress of staying in environmental requirement, the ascendant trend of building energy consumption rigid demand is difficult to reverse, and becomes exercise question in the urgent need to address in China's energy-saving and emission-reduction.In city, what form energy consumption powerful army is not only the new building of everyday rising sheer from level ground, and is more the old building stood in great numbers in city.Thus the reducing energy consumption of old building becomes the opera involving much singing and action that building trade carries out energy consumption Reduction of Students' Study Load.
Building air-conditioning load greatly proportion is that curtain wall and door and window heat trnasfer cause.Glass-wall building rose from western countries from the 1950's, and because of it, to have colourful external decoration effect very fast in global evolution.China's curtain buildings was started to walk from nineteen eighty-three, and the mid-90 forms climax.Adopt curtain wall as peripheral structure, have elegant in appearance, from advantages such as heavy and light, daylighting are sufficient, but the excessive shortcoming of air conditioner load also can not be ignored.Especially the Curtain Wall Design of some old buildings employing is reasonable not, and cause building energy consumption to remain high, and this also just in time illustrating necessity and the urgency of curtain-wall energy-saving, is the inevitable outcome of energy-conservation market development.
The object ultimate to the reducing energy consumption of old building is the reduction realizing energy consumption, but due to the objective factor of each side such as technology, fund, reducing energy consumption difficulty is very large.
Old building is generally glass curtain wall structure, and the diabatic process of curtain wall roughly has three kinds of approach: one is the heat transfer of glass and aluminium alloys (stainless steel) metal sash; Two is curtain wall inner surface and the heat exchange between room air and indoor environment; Three is curtain wall external surface and the heat exchange between ambient air and external environment.In aforesaid way, reduce the first-selection that glass curtain wall structure thermal transmittance becomes building energy conservation, the measure main method that can realize this object at present has: existing single glazing curtain wall is replaced by the lower hollow glass of thermal transmittance; External sunshade or internal sunshade device is installed additional at original curtain wall; Energy-saving film is sticked at existing single-layer curtain wall.
According to the first technical measures, be replaced by Low emissivity hollow glass by existing curtain wall.Not only to remove original curtain wall and accessory, also will re-start installation.This mode drop into comparatively large, risk is higher, smashes original glass and changes energy-saving glass, in addition, also there is the problem that difficulty of construction is high in the waste of the way destroying original glass inherently on a kind of energy.
According to the second technical measures, namely install external sunshade or internal sunshade device additional at original curtain wall.First solar protection devices is for intercepting light, not affecting, so there is no energy-conservation effect to thermal transmittance; Secondly, for external shading device, its difficulty of construction is higher, and external shading device fixture is difficult to install, and be discord with mansion overall appearance even if install also can cause, this construction method is also infeasible.
According to the 3rd technical measures, what namely have single-layer curtain wall sticks energy-saving film, although this way is feasible, and the curtain wall pad pasting duration is short, easy and simple to handle, can reduce the thermal transmittance of curtain wall.But the thermal transmittance reduced is still very low, and energy-saving effect is undesirable.Through reality test, after sticking low-radiation film, internal-external temperature difference can improve 1 ~ 2.5 DEG C, and this shows that so-called low-radiation film, thermal reflecting coating are not obvious to the heat-blocking action of curtain wall in summer.Present stage building pad pasting market is also more chaotic, is no lack of in the industry shoddy dealer, is not a kind of selection of wisdom to the transformation use adhering film to glass of old building glass.
As can be seen from the above, existing technical measures are also not suitable for the reducing energy consumption of old building curtain wall, current building energy conservation market yet do not have a kind of working measure of maturation be the construction technology of hollow glass curtain wall for curtain wall Reconstruction in field.
