Description

A kind of wall body door or window hole structure
Technical field
The present invention relates to a kind of wall body door or window hole structure, particularly a kind of compound insulation wall door/window opening heat-insulating bridge-cut-off and water proof structure.
Background technology
In the body of wall power-saving technology, current energy-saving heat preserving is best, and the energy-saving heat-insulating wall that cost is minimum is an EPS plate thin plastering heat-preserving wall, but also there is a large amount of door and window hole heat bridges in EPS plate thin plastering heat-preserving wall.When door and window is installed in basic unit body of wall middle part,,, see shown in Figure 1 so the hole increases a lot heat transfer because of the insulation layer of door and window hole sidewall is thin; Or because of door and window is installed in basic unit body of wall exterior angle, the outdoor distance of the outer angular distance of basic unit's body of wall is short, and the hole also increases a lot of heat transfers, sees shown in Figure 2." L " of Fig. 1 and Fig. 2 promptly is the outdoor distance of basic unit's body of wall distance of window.EPS plate thin plastering heat-preserving wall still exists hole linear thermal transmittance ψ value to reach the heat bridge of 0.1w/m.k! (drawing numerical value) from " Heilongjiang Province's Residential Buildings Energy 65% design standard ".In the body of wall of window-wall ratio 0.3, hole periphery heat bridge increases body of wall mean thermal transmittance 0.1w/m approximately 2
At the dwelling house balcony slab of encorbelmenting the insulation of the thick EPS plate of 100mm is arranged up and down, during window-wall ratio 0.3, the balcony slab heat bridge is to the about 0.05w/m of the influence of body of wall mean thermal transmittance 2.k (only account for body of wall length 40~50% by balcony slab length), EPS plate thin plastering heat-preserving wall hole heat bridge and balcony slab heat bridge always increase the about 0.15w/m of influence of body of wall mean thermal transmittance 2.k, the big more heat bridge influence of window-wall ratio big more (North China's window-wall ratio about 0.4~0.45).Thus, can draw the insulation of severe cold (B) district residential building main wall body EPS plate thin plastering thermal transmittance that should reach approximately and the insulation layer thickness that needs, see attached list 1.By subordinate list 1 as seen, it is too difficult that energy-saving wall below 8 layers meets the requirements of thermal transmittance, if can reduce the hole heat bridge, dwindles the poor of main wall body heat transferring coefficient and body of wall mean thermal transmittance limit value, and the target of building energy conservation just is easier to realize.Because of door and window hole quantity is many, very big to the influence of body of wall energy-saving heat preserving, door and window hole heat bridge problem is the difficult problem that the whole world does not have solution.
Subordinate list 1 severe cold (B) district residential building is considered linear thermal transmittance and the influence of balcony slab heat bridge, the thermal transmittance that EPS plate thin plastering main wall body should reach approximately and the insulation layer thickness that needs
The number of plies Build coefficient limit value Body of wall mean thermal transmittance limit value w/m 2.k The thermal transmittance w/m that the main wall body should reach approximately 2.k The EPS plate thickness mm that needs

Annotate: be the 0.2mm concrete wall by the main wall body 1,, subordinate list 1 data contain heat-preservation balcony plate heat bridge (accounting for exterior wall length 40~50% by balcony slab length), the hole heat bridge is 0.15w/m to the influence of body of wall mean thermal transmittance 2.k.
2, severe cold (A) district body of wall mean thermal transmittance limit value also need reduce 0.05w/m than (B) district 2.k, the main wall body thermal transmittance that should reach more is difficult to realize.
Other various heat-preserving walls, as sandwiched thermal-insulating wall, steel wire net rack heat-preserving wall, insulation blocks body of wall, inside heat insulation wall body etc., the heat bridge of these heat-preserving walls is too many especially! The body of wall average heat transfer that these bodies of wall all can not satisfy housing construction is no more than 0.75w/m 2.k the requirement of Yi Xia energy-saving wall.2003~2005 years heating seasons of academy of China Constrution Academe part energy saving building follow-on test in Beijing is found, by the building measured result of energy-conservation 50% index formation reach the only energy-conservation 7%! of energy-conservation 37%, energy-conservation 30% building reality Now some areas have begun tentative energy-conservation 65% standard, are subjected to that the body of wall technology is incomplete to be influenced, and also influence reaches the energy conservation object of national regulation.Heat bridge has increased architect's design-calculated difficulty more, and the wall heat transfer amount height because of worrying that these heat bridges are more, does not reach the heating requirement, have to thermal performance design engineer estimate how the building energy conservation target of expection realizes to the heat consumption of body of wall more?
When preceding bad because of the door and window hole waterproof, the thing of destroying composite thermal-insulating wall also happens occasionally.Particularly the waterproofing work of windowsill is bad is the common quality defect of building for door and window hole, and it is more necessary that the heating area prevents that the compound insulation wall door/window opening water inlet from frost heaving failure taking place.The measure of current solution compound insulation wall door/window opening waterproof is after the door and window installation, smear waterproofing mortar around at the outdoor hole of door and window, use the elastic water-proof fluid sealant with the gap sealing between waterproofing mortar and the door-window section bar again, but waterproofing mortar ftractures sometimes, influence waterproof effect.Some energy-saving walls as EPS plate thin plastering heat-preserving wall, do not have waterproofing mortar on the plastering of hole insulation layer, only with the fluid sealant sealing, take place sometimes from the hole water inlet, and winter, frost heave made the phenomenon that the insulation layer of stickup comes off.The macromolecule coil waterproof layer all is to be used for roofing, basement and accomodation ground and metope waterproof at present, does not use it for the door and window hole waterproof.
