Description

A kind of construction technology that curtain wall is processed into the hollow glass curtain wall
Technical field
The present invention relates to the construction technology that a kind of curtain wall scene transform the hollow glass curtain wall as, belong to the energy-saving building technology field.
Background technology
In China, 30% ratio of the energy consumption of the building energy consumption account whole society, with industry power consumption, traffic power consumption and title China three big " energy consumption rich and influential family ", and the increase along with living space, people are to staying in the progress of environmental requirement, the ascendant trend of building energy consumption rigid demand is difficult to reverse, and becomes the exercise question that presses for solution in China's energy-saving and emission-reduction.In the city, what constitute energy consumption powerful army is not only the new building of everyday rising sheer from level ground, and more is the old building in the city of standing in great numbers.Thereby the reducing energy consumption of old building becomes the opera involving much singing and action that building trade is carried out the energy consumption Reduction of Students' Study Load.
Building air-conditioning load proportion greatly is that curtain wall and the transmission of door and window heat cause.Glass-wall building rose from western countries from the 1950's, and to have a colourful outer decorative effect very fast in global evolution because of it.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 abundances, but the excessive shortcoming of air conditioner load also can not be ignored.Especially the curtain wall design of some old buildings employings is reasonable inadequately, cause building energy consumption high, and this also just in time illustrates necessity and the urgency of curtain-wall energy-saving, is the inevitable outcome of energy-conservation market development.
Be to realize the reduction of energy consumption to the ultimate purpose of the reducing energy consumption of old building, but because the objective factor of each side such as technology, fund, the reducing energy consumption difficulty is very big.
Old building is generally glass curtain wall structure, and the diabatic process of curtain wall roughly has three kinds of approach: the one, and the heat transfer of glass and aluminium alloys (stainless steel) metal sash; The 2nd, the heat exchange between curtain wall inner surface and room air and the indoor environment; The 3rd, the heat exchange between curtain wall external surface and ambient air and external environment.In aforesaid way, reduce the first-selection that the glass curtain wall structure thermal transmittance becomes building energy conservation, can realize that at present the measure main method of this purpose has: existing single-glass curtain wall is replaced by the lower hollow glass of thermal transmittance; Install external sunshade or internal sunshade device additional at original curtain wall; The energy-saving film that sticks at existing single-layer curtain wall.
If adopt first kind of technical measures, be about to existing curtain wall and be replaced by low radiation hollow glass.Not only to remove original curtain wall and accessory, also will install again.This mode drops into greatly, risk is higher, smashes original glass and changes energy-saving glass, and the way itself of destroying original glass is exactly the waste on a kind of energy, in addition, also has the high problem of difficulty of construction.
If adopt second kind of technical measures, namely install external sunshade or internal sunshade device additional at original curtain wall.At first solar protection devices just is used for obstruct light, to not influence of thermal transmittance, does not therefore have energy-conservation effect; Secondly, for the external sunshade device, its difficulty of construction is higher, and external sunshade device fixture is difficult to install, and is discord even install also can cause with the mansion overall appearance, and this job practices is also infeasible.
If adopt the 3rd technical measures, namely have the energy-saving film that sticks of single-layer curtain wall, though 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 that reduces is still very low, and energy-saving effect is undesirable.Through reality test, stick low-radiation film after, internal-external temperature difference can improve 1~2.5 ℃, this show so-called low-radiation film, thermal reflecting coating summer to the heat-blocking action of curtain wall and not obvious.Present stage builds pad pasting market and also compares confusion, is no lack of shoddy dealer in the industry, and it is not a kind of selection of wisdom that adhering film to glass is used in the transformation of old building glass.
As can be seen from the above, existing technical measures also are not suitable for the reducing energy consumption of old building curtain wall, yet do not have a kind of working measure of maturation to transform the construction technology of hollow glass curtain wall as at the curtain wall scene at present on the building energy conservation market.
