Abstract

Disclosed is a composite automatic heat insulation building block, which belongs to a heat insulation building block. The building block is formed by a heat insulation inner core and an outer layer, wherein materials of the heat insulation inner core are chosen from foamed concrete, foaming plaster, cenosphere foaming materials or expanded perlite, and the whole outer surface of the heat insulation inner core is coated by the outer layer. A material of the outer casing thereof is gypsum cement or cement. The heat insulation building block not only is adaptable to bearing walls, but also is adaptable to partition walls. A wall body is built at one time without mortar facing. The composite automatic heat insulation building block has the advantages of simple construction, low cost and having fine thermal insulation property.

Description

Composite thermal self-insulation building block

Technical field

The utility model relates to building wall block, and heat insulating composite building block particularly for building is made the field.

Background technology

Existing external wall heat insulation system is: 1, the thin system of wiping one's face of EPS plate; 2, rubber powder EPS granule thermal insulation slurry outer heat preservation system; 3, the compound no netting wire frame plate outer heat preservation system of cast-in-situ concrete; 4, cast-in-situ concrete composite steel wire network frame plate outer heat preservation system; 5, rock wool outer heat preservation system; 6, mechanical fixation EPS gauze wire cloth frame plate outer heat preservation system; 7, hard-foam polyurethane outer heat preservation system; 8, XPS plate outer heat preservation system etc.The shortcoming of above-mentioned external wall body thermal insulation system: 1, construction is numerous and diverse, with high costs; 2, service life short (10～25 years); 3, be easy to generate cracking, hollowing, obscission; 4, Zui Da harm still is environmental protection hidden danger.The existing building building block has Normal concrete small hollow block, the steam pressurized air-entrained concrete building block, Lightweight aggregate concrete small hollow block, fly ash building block, gypsum block, the flyash one hand tile, (" novel wall material handbook, second edition, Chinese building material industry publishing house such as hollow clay building block, June calendar year 2001 the 2nd edition, P269-336).The wall thermal insulating heat-insulating problem is not all considered in above-mentioned building block specially, in addition, also has foam concrete block (" novel wall material handbook, P341 ") it adopts cement foam concrete (adding foaming agent and water stirring, moulding in cement and the filler) or (flyash is main to adopt the silicate foam concrete, add lime, gypsum, foaming agent and water, stirring, moulding) make, it has thermal and insulating performance, but, its intensity and bearing capacity are not enough, if as partition wall, the surface also needs constructions such as mortar decorative cover levelling.In addition, also have with the building block of foam concrete insulation layer as sandwich, its shortcoming one is block insulation layer place insufficient strength, fracture easily; The 2nd, insulation layer exposes, and influences block surfaces intensity.

The utility model content

The purpose of this utility model provides a kind of composite thermal self-insulation building block that does not need again mortar facing, no heat bridge to produce, have better heat-insulating property.

This novel purpose is achieved in that a kind of composite thermal self-insulation building block, comprise building block, building block being formed at the skin of insulation inner core whole outer surface by the insulation inner core and the cladding of material by being selected from foamed concrete, foaming plaster, cenosphere expanded material or expanded perlite.

A kind of specifically scheme is that building block is a rectangle, and its length * wide * height is respectively 600 * 500 * 90～180mm, and is equipped with a pair of tenon and tongue-and-groove respectively on its upper and lower side and the left and right side.Selenite cement is that the outer field thickness of material is 15～30mm.

Another kind of scheme is that building block is a cuboid, its length * wide * height is respectively 390 * 190 * 190mm, and its upper and lower, left and right are respectively arranged with the perforation Baltimore groove on four sides, material is anti-water modified gypsum or cement, the outer layer thickness that connects on the Baltimore groove is 5～15mm, and the outer layer thickness on its lap is 20～30mm.

The advantage of composite self-insulation system is:

1, body of wall and insulation are accomplished without any letup, and it is simple, with low cost to construct.

2, long-term firm durable, heat-insulating property is not lost, and wind resistance and air stability are good.

3, fire-resistant, waterproof, freeze proof, shock resistance, sound insulation property are good, can long-term moistureproof, anti-moisture absorption etc.

4, pollution-free, radiationless, environmentally-friendly sanitary.

5, this architecture uniqueness, no heat bridge produces, and 200 walls can reach 65% energy-saving index.

6, not only be applicable to load bearing wall,, but also be applicable to partition wall, for load bearing wall, can adopt the cement skin, be about to be incubated the inner core cladding in cement shell, the hollow cement shell is as load-bearing skeleton, its load holding capacity is bigger; For partition wall, only need to adopt selenite cement (cement mixed weight 5～10%) to satisfy the demands.

7, this novel load bearing wall building block and partition block, flat appearance behind the last wall all unnecessaryly carries out the sand finish levelling and constructs.

8, heat insulating effect is better

Owing to adopt foamed concrete to make the insulation inner core, and the insulation inner core is cladded in a closed shell, therefore has better heat insulating effect.The inner insulation inner core that is the closed pore shape, its better effects if are made in cenosphere expanded material (as the application number 2006100202564) foaming that also can adopt the inventor to develop.

9, the inventor has developed corresponding building block special-purpose machines and tools, semi-automatic and fully-automatic production building block, and production efficiency is higher.
