Description
Technical field
The invention belongs to building operations technical field of structures, relate to a kind of wall, particularly a kind of self-insulation wall structure.
Background technology
In recent years, the whole society advocates energy-conservation of consumption reduction and sustainable development, the energy-conservation state basic policy having become China, and according to incompletely statistics, China's architectural energy consumption accounts for 27.8% of social total burn-off, architectural energy consumption generally comprise air-conditioning, heating, light, with water etc.Along with the high development of China's city-building, the building total amount of nearly 2,000,000,000 square metres every year, in the development in future, building energy consumption will rise to more than 35% of social total energy consumption, therefore, promote building energy conservation, can reduce whole society's building energy consumption, common people can be allowed again to improve the quality of living, be the major issue of benefiting the nation and the people.The important step of building energy conservation is that body of wall is energy-conservation, the heat-insulating property improving building enclosed structure is that the necessity reducing building energy consumption is handled affairs, current outer wall heat preservation system is varied, heat insulating material is various, exterior-wall heat insulation refers to adopt certain fixed form bonding, mechanical anchor, stickup+mechanical anchor, spraying, cast etc., the good thermal insulation material of lower for coefficient of thermal conductivity heat insulating effect and building masonry wall are fixed as one, increase the evenly heat tissue of body of wall, thus reach a kind of engineering way of insulation or effect of heat insulation, and the fire-protection rating that exterior-wall heat insulation requires now requires also progressively to improve, in order to solve the problem, Chinese patent [number of patent application: 201120260854.5] discloses a kind of self-insulating composite external wall, comprise body of wall basic unit, described body of wall basic unit is that concrete structure body of wall and air-entrained concrete building block insulation layer are composited or air-entrained concrete building block is built by laying bricks or stones and formed, basic unit's cross section agent leveling layer is outwards disposed with from body of wall basic unit, completely spread hot-galvanized steel silk screen, surface layer leveling layer and anticracking grout surface layer.This patent has structure and insulation layer is integrated, fiery residence odds can be reduced while guaranteeing insulation, but the interior gauze wire cloth of this structure, after using a period of time, corrosion can be produced, what situation was serious even can destroy whole external wall system, and such external wall structure also easily causes the problem such as contraction, crack, even hollowing.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of self-insulation wall structure, its long service life, cracking resistance, good heat insulating.
Object of the present invention realizes by following technical proposal: a kind of self-insulation wall structure, it is characterized in that, comprise body of wall basic unit and build the beam column basic unit on body of wall basic unit, the external surface of described beam column basic unit is lower than the external surface of body of wall basic unit, the external surface of described beam column basic unit is disposed with interface agent layer from the inside to the outside, heat-insulation mortar bed, plastering sand pulp layer and decorative layer, described heat-insulation mortar bed external surface is equal with the external surface of described body of wall basic unit, described plastering sand pulp layer and decorative layer are successively set on the external surface of body of wall basic unit from the inside to the outside, described heat-insulation mortar bedly have strengthening grid cloth with the arranged outside of the intersection of body of wall basic unit, the top of described strengthening grid cloth is arranged between heat-insulation mortar bed and plastering sand pulp layer, the bottom of described strengthening grid cloth is arranged between body of wall basic unit and plastering sand pulp layer.
In the technical program, be arranged on heat-insulation mortar bed upwards extension with the strengthening grid cloth on the external surface of the intersection of body of wall basic unit and cover thermal insulation mortar skin, downward extension local covers in body of wall basic unit, this strengthening grid cloth has Stability Analysis of Structures, intensity is high, alkaline resistance properties good, the features such as anticorrosion, cracking resistance, it is relative to the wire lath of easy-to-rust, strengthen best results, longer service life, can avoid heat-insulation mortar bedly easily producing crack with body of wall basic unit intersection, easily oozing water problem effectively.
In above-mentioned self-insulation wall structure, described strengthening grid cloth is provided with anticracking grout layer.Anticracking grout layer is attached on strengthening grid cloth, difficult drop-off, and anticracking grout layer matches with strengthening grid cloth simultaneously, and effect of prestressed is better.
In above-mentioned self-insulation wall structure, describedly heat-insulation mortar bedly to make for polymer inorganic thermal insulation mortar material.Inorganic polymer thermal insulation mortar becomes by silicate cement, activated silica, multiple polymers, nanometer stream the mortar with incubation and thermal insulation function helping and configure into agent, fiber, high-temperature calcination surface-treated inorganic salts ore, its coefficient of thermal conductivity is 0.070, application life can be synchronous with building, it has noninflammability, there is good fireproofing function, preferably make with closed perlite material, and it also has good water proofing property, thus the setting of waterproof mortar course can be reduced.
In above-mentioned self-insulation wall structure, describedly heat-insulation mortar bedly to make for polymer inorganic light-weight aggregate thermal insulation mortar material.Loose volume weight is adopted to be less than 1000 kg/ms in the technical program
3polymer inorganic porous aggregate as the material source of mortar, as adopted industrial waste light aggregate, being preferably haydite, adopting above-mentioned light aggregate, not only insulated fire better effects if, and realize the recycling to industrial waste, achieve energy-conserving and environment-protective.
In above-mentioned self-insulation wall structure, described decorative layer is made up of the facing mortar being sprayed on plastering sand pulp layer external surface.Facing mortar can be adjusted to shades of colour in advance, only need spray on plastering sand pulp layer external surface, good decorating effect, and the durability of facing mortar is identical with Building life cycle.
