Description

Inorganic fire-retarded composite thermal-insulating wall

Technical field

The utility model belongs to building masonry wall heat preservation technology field, is a kind of inorganic fire-retarded composite thermal-insulating wall.

Background technology

In known technology, highrise building is divided into framework or frame structure, and the exterior wall that body of wall is generally built by laying bricks or stones by concrete beam, concrete column or common light-weight brick forms.At present, general construction wall preparation method is to adopt non-bearing building block and masonry of cement mortar filled wall, then at body of wall, lays insulation layer outward again.Insulation layer is generally divided three classes; One generic organic material, as organic materials such as polyphenyl plate, extruded sheet, glue powder polyphenyl particles, although the heat-insulating property of this class heat insulating material can reach national heat preservation energy-saving standard-required, its fire protection flame retarding, ageing resistace are poor, easily initiation fire accident.Another kind ofly belong to inorganic slurry class material: as thermal insulation mortar, such heat insulating material used thickness hour, do not reach heat preservation energy-saving requirement, thickness easily ftractures, comes off while increasing, and affects result of use, and the life-span is short, it is loaded down with trivial details that while insulation layer is deposited with working procedure, time-consuming, the construction period is long, and expense is high.The 3rd class belongs to inorganic plate: as rock wool, glass wool thermal insulation board, this type of heat insulating material not only cost is high, and production capacity is low, and not environmental protection.Cold or the hot summer and warm winter region for Xia Redong, the surface of wall of normally building by laying bricks or stones at common brick is deposited with thermal insulation mortar material, for reaching national energy-saving standard-required, heat-insulation mortar bed thickness need to be designed into about 80mm, and heat-insulation mortar bed for this thickness not only needs during construction to construct several times, both loaded down with trivial details, also dangerous, and high material consumption, uneconomical.In the recent period, disclosedly on market fill out core insulation blocks, although there is the insulating power that is better than common brick, but still do not reach the energy-saving design standard-required of country 65%.This core insulation blocks of filling out is in building-block, to fill slag, stalk, common perlite particle or various organic material, although the heat-insulating property of body of wall obtains improvement to a certain extent, but the core material that the body of wall of making is only building block centre has heat preservation and insulation, and the heat bridge position of building block periphery is more, whole body of wall is distributed inevitably and form heat bridge or cold bridge, cause heat insulation and preservation effect undesirable, although common air-entrained concrete building block has certain heat preservation and insulation, but do not reach existing national energy-saving standard-required, therefore still need to make thicker insulation layer, just can reach energy-conservation requirement, so be difficult to promote.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides that a kind of thermal and insulating performance is good, economical and practical, the inorganic fire-retarded composite thermal-insulating wall of easy construction, safety and environmental protection.

Realizing the technical scheme that the purpose of this utility model takes is: this heat-preserving wall comprises concrete beam and column and exterior wall, wherein, exterior wall adopts compound insulation structure, to be formed by the self-heat-preservation energy-saving air-entrained concrete building block of building by laying bricks or stones and inorganic heat insulation mortar layer, inorganic heat insulation mortar layer covers and is sticky deposited on the external surface of building block and the external surface of concrete beam and column, on the external surface of inorganic heat insulation mortar layer, is made with finish coat.

Described inorganic heat insulation mortar layer adopts I level for building or II level inorganic heat insulation mortar, and the overburden cover of its mortar is 20mm～50mm.

Described self-heat-preservation energy-saving air-entrained concrete building block, adopts the patented technology by formerly separate case application of the applicant, and the patent No. is: ZL201110063809.5, patent name is: a kind of self-heat-preservation energy-saving wall of aerated concrete block and preparation method thereof.

In this case, exterior wall adopts self-heat-preservation energy-saving air-entrained concrete building block to add the compound insulation structure of the inorganic heat insulation mortar bed of material, and this insulation construction not only can meet national energy-saving standard-required, and the compressive strength of body of wall is high, and impact resistance is strong.Meanwhile, with inorganic heat insulation mortar, replace ordinary mortar as the bonding cladding material of building block, between building block, form closed insulating, can effectively eliminate the heat bridge in body of wall, greatly strengthen the heat preservation and insulation of body of wall; And the adhesive strength of inorganic heat insulation mortar is also better than ordinary mortar, eliminate thus the phenomenons such as the relative expanding compression deformation difference of body of wall and various materials thereof and aging, cracking, damage, in the application life that extends body of wall, make the body of wall of building by laying bricks or stones remain good heat preservation and insulation.

The inorganic fire-retarded composite thermal-insulating wall of making according to such scheme, its beneficial effect is:

1) the self-heat-preservation energy-saving air-entrained concrete building block that the utility model adopts, its material mainly have drawn from flyash or river sand, and the best of breed of some industrial wastes and thermal insulation material, realized the raising of comprehensive utilization of resources and properties of product.The exterior wall of building by laying bricks or stones with this self-heat-preservation energy-saving aerated-block, can improve the combination property of heat-preserving wall, can make the coefficient of thermal conductivity of body of wall be controlled at 0.11～0.12 w/(mk), meet energy-conservation 65% design standard even higher, compressive strength can reach 3.5～5.0Mpa, meets the requirement of construction wall peripheral structure.

2) this body of wall on the make, use the self-heat-preservation energy-saving air-entrained concrete building block of state-of-the-art technology, and adopt inorganic heat insulation mortar, this just fundamentally solved current foam heat-insulating board outer heat preservation system institute ubiquitous inflammable, application life is short, poisonous and harmful, and thermal insulation mortar insulation layer thickness after increasing easy to crack, come off, the problem such as hollowing, construction are complicated, uneconomical.

3) this body of wall is used self-heat-preservation energy-saving aerated-block and thermal insulation mortar material all be take natural inorganic mineral matter as raw material, have nontoxic, tasteless, be stale-proof, the multiple superperformance such as fire-retardant, heat-insulation and heat-preservation, environmental protection, by two kinds of heat insulating material combinations, can reach country about the energy-conservation design standard requirement of building heat preserving, thereby effectively guarantee that being incubated the life-span synchronizes with building, can reduce the integrated cost of body of wall manufacturing cost and building greatly.
