Description
Technical field
The utility model relates to the wall that is specifically designed to insulation, specifically a kind of heat-preserving wall.
Background technology
China builds up first hand autoclaved aerated concrete factory from nineteen sixty-five, produces autoclaved aerated concrete piece and sheet material that construction walling or roofing are used heat preservation energy-saving, so far extensive use in China.When masonry panel, need use masonry of cement mortar, because low its coefficient of thermal conductivity of the heat-insulating property of cement mortar more than 5 times, causes the wall insulation performance of autoclaved aerated concrete piece to reduce more than 30% much larger than the coefficient of thermal conductivity of autoclaved aerated concrete.Although building a wall, research and use autoclaved aerated concrete have more than 80 year history in China and Europe, so far international, the domestic extremely low problem of scientific method solution cement mortar heat-insulating property that there is no.
And in the prior art, numerous measures adopt metope to add in addition the insulation layer mode, and the heat preserving exterior wall that for example is used for autoclaved aerated concrete is done 50 millimeters insulating layer of external wall usually in addition.Not only cost is high, and construction is complicated and long in time limit.
The utility model content
The utility model is exactly in order to solve in the prior art, and the body of wall of traditional autoclaved aerated concrete is because of the extremely low problem of the impact heat-insulating property of cement mortar, and a kind of heat-preserving wall that is provided with disconnected heat bridge band in body of wall is provided.
The utility model is realized according to following technical scheme.
A kind of heat-preserving wall comprises building block and interconnective screed therebetween, and is gripped with same thickness with it, certain width, coefficient of thermal conductivity less than the disconnected heat bridge band of screed in screed.
Described heat-preserving wall, sandwiched disconnected heat bridge band is to have or without the rock wool strip of coating layer in its screed.
The utility model of design improves the cement mortar thermal resistance more than 8 times like this, and heat-insulating property improves more than 30%, and heat insulation effect is remarkable; Material source is abundant, and is with low cost, and the cost amount of decrease reaches 37.5%, greatly saves for heat energy, and the cement mortar that is through with mortar joint is not incubated history.The utility model is not only applicable to autoclaved aerated concrete bulk (containing wallboard, roof panel), also is applicable to all light heat-insulation wall materials for building; Simplify the engineering construction operation, accelerated construction speed.Become on China and even the international construction engineering, have the major reform of the energy-conserving construction wall of historic significance.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
A kind of heat-preserving wall comprises building block 1 and interconnective screed 2 therebetween, and is gripped with same thickness with it, certain width, coefficient of thermal conductivity less than the disconnected heat bridge band 3 of screed 2 in screed 2.
Screed 2 is generally the cement mortar of water cure; Disconnected heat bridge band 3 is to adopt the little 20 times solid material of coefficient of thermal conductivity of thermal conductivity ratio cement mortar to make, in order to increase the thermal resistance of screed 2.
Described heat-preserving wall, sandwiched disconnected heat bridge band 3 is to have or without the rock wool strip 5 of coating layer 4, with or without the glass wool strip (not shown) of coating layer in its screed 2.
Described heat-preserving wall, sandwiched disconnected heat bridge band 3 is flame retardant type foamed plastics section bar 8 in another embodiment in its screed 2.
Described heat-preserving wall, the thin-wall plastic tubing 6 of the square or rectangle of the single hole that sandwiched disconnected heat bridge band 3 is the wide 6-18mm in hole in another embodiment in its screed 2 or porous arranged side by side.The median septum 7 of integrally formed not ventilating air in the thin-wall plastic tubing 6 of diplopore arranged side by side, the thin-wall plastic tubing 6 of every wide 12mm in hole is most preferred embodiment.
Described heat-preserving wall, sandwiched disconnected heat bridge band 3 is many not moving air grooves that width is 6-18mm arranged side by side in its screed 2.(not shown).
Described heat-preserving wall, disconnected heat bridge band 3 sandwiched in its screed 2 successively is crisscross arranged.
Described heat-preserving wall, disconnected heat bridge band 3 edges sandwiched in its screed 2 are not less than 80 millimeters far from wall face.
Described heat-preserving wall, disconnected heat bridge band 3 cross sections sandwiched in its screed 2 are 15mm * 50-80mm, and are isometric along length and the body of wall of putting disconnected heat bridge band 3; Erect the length of putting disconnected heat bridge band 3 identical with the height of building block 1.
Described heat-preserving wall, its building block 1 autoclaved aerated concrete, or fly ash hollow brick, or building-block.
During enforcement of the present utility model, on the horizontal surface that has spread building block 1, prolonging wall length straight in mortar joint, settle one to have or without the rock wool strip 5 of coating layer 4,15 millimeters of 50～80 millimeters of its width, height and screed 2(mortar joint as an example of cold district example) thickness is identical.The autoclaved aerated concrete wall that adopts the utility model to build by laying bricks or stones, its thickness only namely satisfies the energy conservation criteria standard with 250 millimeters.When adopting a disconnected heat bridge band 3, its edge is not less than 80 millimeters far from wall face, namely reserves the stressed screed in border.If reduce screed 2(mortar joint because placing disconnected heat bridge band 3) the total bearing capacity of area effect mortar, can suitably improve grade of mortar in case of necessity.When wall thickness during greater than 250 millimeters, can place 2 disconnected heat bridge bands, all inside and outside the wall crust, be not less than 80 millimeters.Disconnected heat bridge band after the laying every 1 meter temporary fixed with mortar, also availablely be not less than 30 millimeters iron nails and fix.Next step construction is namely by this wall building method, successively builds by laying bricks or stones and the heat bridge band 3 that will break is staggeredly placed.2 of the perps screeds heat bridge band 3 that will break is placed perpendicular to the upper surface of wall, and it highly is that building block 1 thickness adds horizontal mortar thickness.The thickness of disconnected heat bridge band 3 is identical with perpends.The thick steam pressurized concrete wall of the 250mm that the utility model is built by laying bricks or stones with existing autoclaved aerated concrete heat preserving exterior wall, is namely built a wall with conventional cement mortar and is added insulating layer of external wall and compare, and its cost amount of decrease reaches 37.5%.Severe cold area is for reducing thermal transmittance, can be in the wall thickness such as autoclaved aerated concrete and disconnected heat bridge band quantity because of the ground adjustment.
Like this, guarantee to realize in advance the green building planning of the year two thousand twenty national requirements energy-conservation 30%.The utility model will become China and even have in the world the energy-conserving construction wall major reform of historic significance.
