Abstract
The utility model discloses a passive form low energy consumption ground does not have key node of heat channel, including concrete foundation outer wall and concrete floor, be equipped with outer wall external thermal insulation layer in the periphery of concrete foundation outer wall, have a ground heat preservation at concrete floor, outer wall external thermal insulation layer constitute by upper and lower two sections outer wall external thermal insulation layer, upper and lower section outer wall external thermal insulation layer's boundary position is higher than concrete floor, ground heat preservation and outer wall external thermal insulation layer seamless connection. It is one of key node of passive form low energy consumption, through with the seamless connection of ground heat preservation with outer wall external thermal insulation layer, has realized afebril bridge node's design, can avoid producing the heat channel, does not have the heat loss, practices thrift the energy consumption by a wide margin.
Description
Technical field
The utility model belongs to technical field of buildings, particularly relates to the structural improvement of the key Nodes in a kind of ground (particularly in architectural exterior-protecting construction, some easily produce the position of heat bridge).
Background technology
Along with more urgent to energy saving requirement of people, passive type energy saving building technology has developed and has come, it is that the peripheral protective system utilizing heat-insulating property preeminent is down to the energy loss in room minimum, is not only applicable to house, is also applicable to the buildings such as office, school, kindergarten and supermarket.At present, the emphasis of this technology mainly gets down to: 1, outstanding heat-preserving wall (without heat bridge design); 2, electric energy-saving; 3, the door and window technology of innovation; 4, the ventilation system of High Efficiency Thermal recovery; 5, good tightness.
But for any building, the heat-insulating property of foundation ground also should be can not ignore, and the space enclosing structure of foundation ground is general as shown in Figure 2 in the past: concrete foundation exterior wall 5 and concrete surface 1 adopt seamless link, external wall insulating layer 6 is arranged with at the outer of concrete foundation exterior wall 5, ground insulating layer 2 is had at concrete surface, and the key Nodes in ground external wall insulating layer generally by unlike material two sections of insulation layers (on, hypomere external wall insulating layer 61, 62) form, wherein, described epimere external wall insulating layer adopts rock cotton board 61, hypomere external wall insulating layer (that is being plinth section) adopts graphite polystyrene board 62, on this, the position, boundary of hypomere external wall insulating layer should a little more than concrete surface 1.Under this kind of structure design, concrete foundation exterior wall 5 thickness M ' is generally 250mm, its base foundation section respectively to two lateral direction wide go out 50mm.
Due to the junction of external wall insulating layer 6 and ground insulating layer 2 block by concrete foundation exterior wall 5, therefore can heat bridge be produced and cause the loss of heat, being unfavorable for energy-conservation.
Summary of the invention
The purpose of this utility model is to provide a kind of Passive low-energy ground without the key node structure of heat bridge, and it can overcome defect of the prior art, effectively avoids the generation of heat bridge phenomenon.
For achieving the above object, the utility model takes following design scheme:
A kind of Passive low-energy ground is without the key node structure of heat bridge, comprise concrete foundation exterior wall and concrete surface, external wall insulating layer is arranged with at the outer of concrete foundation exterior wall, ground insulating layer is had at concrete surface, described external wall insulating layer is made up of upper and lower two sections of external wall insulating layers, and the position, boundary of upper and lower section of external wall insulating layer is higher than concrete surface; Described ground insulating layer and external wall insulating layer seamless link.
Described Passive low-energy ground is without in the key node structure of heat bridge, and described hypomere external wall insulating layer adopts XPS extruded polystyrene board to be good.
Described Passive low-energy ground is without in the key node structure of heat bridge, and the bottom rest position of described external wall insulating layer is: at least 1000mm below local frost penetration.
The utility model Passive low-energy ground is one of key node of Passive low-energy without the key node of heat bridge.
The utility model has the advantages that: by the seamless link by ground insulating layer and external wall insulating layer, achieve the design without heat bridge node, can avoid producing heat bridge, there is no heat waste, significantly save energy consumption.
Accompanying drawing explanation
Fig. 1 is that the utility model Passive low-energy ground is without the key node structure schematic diagram of heat bridge.
Fig. 2 is the ground routine way structural representation of prior art.
In figure: 1-concrete surface; 2-ground insulating layer; 5-concrete foundation exterior wall; 6-external wall insulating layer; 61-rock cotton board; 62-graphite polystyrene board; 63-extruded polystyrene board.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
Detailed description of the invention
As shown in Figure 1, the utility model Passive low-energy ground without the key node structure of heat bridge mainly for the improvement of various constructure ground space enclosing structure, comprise concrete foundation exterior wall 5 and concrete surface 1, be arranged with external wall insulating layer 6 at the outer of concrete foundation exterior wall 5, have ground insulating layer 2 at concrete surface.
Main innovation design of the present utility model is, described ground insulating layer 2 is done seamless link with external wall insulating layer 6, can directly avoid like this producing heat bridge.
Further design is, see Fig. 1, the hypomere external wall insulating layer of external wall insulating layer 6 is adopted XPS extruded polystyrene board 63(extrusion moulding type polystyrene heat insulating board), it has extremely low water imbibition (absorbing water hardly), low thermal conductivity coefficient, high pressure resistance and ageing resistance, more superior compared with the graphite polystyrene board performance used in prior art.
Owing to adopting above-mentioned design, the laying length (short transverse) of the utility model external wall insulating layer 6 can reduce to some extent, only need ensure the position of ending bottom it at least 1000mm(H=1000mm below local frost penetration), comparatively prior art shortens to some extent, but performance can meet the demands completely.
Owing to adopting above-mentioned global design, the main wall body thickness M of the utility model concrete foundation exterior wall 5 can be reduced to some extent from 250mm in the past, can appropriateness minimizing use constructional materials.
For other parts (such as frostproof course) in ground enclosing structure, routine techniques process can be adopted, do not repeat herein.
The utility model the improvement of key node can realize the well-tuned of interior temperature by the space enclosing structure of building self.
The various embodiments described above can not to depart under scope of the present utility model in addition some changes, thus above explanation to comprise and the structure shown in accompanying drawing should be considered as exemplary, and be not used to limit the protection domain that the utility model applies for a patent.
