Abstract

The invention discloses an emblem type self-insulation cavity wall which is composed of two parts, i.e. a hollow wall and ultra-light porous insulation cement-based filler. The wall is a cavity wall which is built on basis of a cavity building method and used for bearing weight, cavities are reserved in equal-elevation flat brick layers, thus facilitating the ultra-light porous insulation cement-based filler to smoothly enter the cavity part at the next layer through the cavities when pouring the ultra-light porous insulation cement-based filler; and the intermediate filer is formed by pouring an ultra-light porous insulation cement-based material the dry density of which is less than 300kg/m<3>. On the basis of not changing the architectural style of the traditional emblem type cavity wall, the thermal insulation property of the emblem type cavity wall is greatly improved through integrally pouring the ultra-light porous insulation cement-based material to the cavity part. The invention has simple operation, low cost, excellent thermal insulation effect and very broad application development prospect, and the cavity ball has the function of bearing weight and can serve as a pouring template of the ultra-light porous insulating cement-based filler material.

Description

A kind of emblem formula self-heat conserving cavity wall body and preparation method thereof
Technical field
What the present invention relates to is on the basis that does not change traditional emblem formula cavity wall body architectural style, by the adiabatic cement-based material of ultralight porous is integrated poured to empty bucket part, forms integral type thermal insulation body of wall and preparation method thereof.This emblem formula self-heat conserving cavity wall body can be applicable to the enclosed structure of various multilayers or highrise building.
Background technology
Builing industry is China's pillar industry, and builing industry consumes the energy in the whole world about 1/3.At present, belong to high energy consumption in China overwhelming majority building, the 2-3 that the unit area heating energy consumption is equivalent to the close country of weather conditions in the world doubly, these highly energy-consumings buildings have consumed China a large amount of valuable and the rare energy, serious environment pollutions simultaneously.In addition, China is a people in the countryside big country, 800,000,000 life of farmers is arranged in the rural area, and its house adopts that the locality is easy to get, cheap constructional materials is built by traditional handicraft and formed more, does not take heat insulation measure, and the house energy consumption is big, comfort level is low.Wherein in China's traditional residence, " emblem group " building tool is a kind of typical case and representational architectural style, is the main construction method in rural area, the south of the River.Therefore, fully excavating " emblem group " traditional residence constructional materials performance, on the basis of building construction mode and understanding local resources situation, utilize modern building technology and manufacturing process transformation and promote traditional residence construction material heat preservation and insulation, and local leading heat insulating material of exploitation and the compound novel self heat insulation wall of traditional emblem formula body of wall, not only can continue and pass on " emblem group " culture of traditional residence characteristic, and for developing a circular economy, environmental protection and energy saving, the new socialist countryside is built, advance China's building energy conservation work also to be of great practical significance, the application and development prospect is very wide.
Summary of the invention
Technical problem: the objective of the invention is on the basis that does not change traditional emblem formula cavity wall body architectural style, a kind of simple to operate, wide material sources, with low cost, a kind of emblem formula self-heat conserving cavity wall body that heat insulating effect is excellent and preparation method thereof are provided.This emblem formula self-heat conserving cavity wall body can be applicable to the enclosed structure of various multilayers or highrise building.
Technical scheme: the present invention is directed to the deficiencies in the prior art and defective, on the basis that does not change traditional emblem formula cavity wall body architectural style, by forming the cavity wall body that an integral body connects to reserving the cavity mode with absolute altitude dormancy brick layer; (dry density is less than 300kg/m with the ultralight of good fluidity then 3) the integrated poured sky bucket part that arrives of the adiabatic cement-based material of porous, finally form an integral type thermal insulation body of wall.
This body of wall is to be made of cavity wall body and the adiabatic cement based packing material of ultralight porous two parts;
Described cavity wall body is to build the cavity wall body that is used for load-bearing that forms by laying bricks or stones by the block method that struggles against by emblem formula sky, but is reserving cavity with absolute altitude dormancy brick layer, and the adiabatic cement based packing material of ultralight porous is poured into down the cavity of one deck cavity wall body by these cavitys;
The adiabatic cement based packing material of described ultralight porous is that dry density is less than 300kg/m 3Ultralight honeycombed cement sill.
This preparation method is:
1) builds the cavity wall body by laying bricks or stones by the empty bucket of emblem formula block method;
2) the adiabatic cement based filling paste of preparation ultralight porous;
3) filling paste is adopted pumping technology or pouring mode are poured into empty bucket part, with the self heat insulation wall of an integral body of cavity wall body formation from the upper entrance of body of wall.
Beneficial effect: the present invention is simple to operate, with low cost, heat insulating effect is excellent, and the cavity wall body has the double again cast template of doing the adiabatic cement-based material of ultralight porous of weight-bearing function.Not only can continue and pass on " emblem group " culture of traditional residence characteristic, and for develop a circular economy, environmental protection and energy saving, new socialist countryside construction, advance China's building energy conservation work also to be of great practical significance, the application and development prospect is very wide.This emblem formula self-heat conserving cavity wall body can be applicable to the enclosed structure of various multilayers or highrise building.
Description of drawings
Fig. 1 is a kind of emblem provided by the invention formula self-heat conserving cavity wall body schematic diagram.
Wherein have: cavity wall body 1, the adiabatic cement based packing material 2 of porous, reservation cavity 3.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
With reference to accompanying drawing, this embodiment comprises: cavity wall body 1, the adiabatic cement based packing material 2 of ultralight porous, reservation cavity 3.During construction, at first build the cavity wall body by laying bricks or stones by the empty bucket of emblem formula block method; Then prepare the adiabatic cement based filling paste of ultralight porous; At last filling paste is adopted pumping technology or pouring mode to be poured into empty bucket part, with the self heat insulation wall of an integral body of cavity wall body formation from the upper entrance of body of wall.
Embodiment 1:
With the local cement brick commonly used in present Anhui is building materials, uses yellow mud as cementing agent, by the empty bucket of emblem formula block method masonry panel, by reserving the cavity wall body that the cavity mode forms an integral body perforation with absolute altitude dormancy brick layer; By industrial residues such as adding coal ash in cement matrix and mine tailings, utilize the foaming of protide blowing agent, cement slurry and blowing agent are mixed the adiabatic cement based filling paste of formation ultralight porous, concrete prescription is as follows; Filling paste is poured into empty bucket part from the upper entrance of body of wall, forms the self heat insulation wall of an integral body with the cavity wall body, its thermal and insulating performance was tested in maintenance in 7 days under field conditions (factors).
