Description
Technical field
The present invention relates to a kind of constructional materials, relate in particular to a kind of sandwich block.
Background technology
The building block that forms at present building masonry wall is hollow concrete building block substantially, though the building block of this hollow structure has alleviated the weight of body of wall to a certain extent, but there is the problem of following several respects: the first, there is very strong heat bridge effect, heat preservation and insulation is poor, and the body of wall that this Hollow building block stacks, its hollow parts has formed the air convection channel of body of wall inside, thereby the heat-insulating property of body of wall is further reduced; It two is, impact resistance and bearing strength relatively a little less than, easily produce micro-crack and even ftracture; It three is, the bonding surface of building block and building block is little, and the stabilized structure of body of wall is lowered relatively, generally makes up by strengthening building block size, thereby has increased the floor space of body of wall; It four is, some tends to fall into the hole of its hollow the mortar of joint block, causes the waste of mortar; It five is, quality is coarse, and size is accurate not, and the surface of wall that is built into is coarse, out-of-flatness, not attractive in appearance, needs to decorate, time-consuming, increases cost; It six is, water resistance is bad, and the moisture content of body of wall can change with the variation of ambient humidity, thereby the frost resistance to body of wall and durability produce harmful effect.In addition, it also and previous use be that fragment of brick is the same, while piling up, affected by operator's technical level larger for positioning precision, thereby to the having relatively high expectations of operator,, quality stability is poor for the deviation of its positioning precision.
Summary of the invention
Object of the present invention be exactly for above-mentioned prior art deficiency, design a kind of wall heat insulation of being built into of making, and the smooth building block of decorating of not needing attractive in appearance of surface of wall.Foregoing invention object is achieved through the following technical solutions:
Described sandwich block, comprise skeleton, core body and decorative layer, the gusset of at least two vertical handing-over in described skeleton comprises a rectangle frame and is located at this rectangle frame, described core body is filled in the rectangular grid being formed by skeleton and gusset, two decorative layers are separately positioned on a side of the maximum side that two of described rectangle frame is parallel to each other, and the top and bottom of two decorative layers, respectively lower than the top and bottom of skeleton, make the top and bottom of described building block form respectively a boss and groove.
Sandwich block of the present invention is characterised in that, on the relatively little two sides that two of described rectangle frame is parallel to each other, is respectively equipped with slot pulling.
Sandwich block of the present invention is characterised in that, the lower end of the relatively little two sides that two of described rectangle frame is parallel to each other is provided with mortar die cavity.
Sandwich block of the present invention is characterised in that, described mortar die cavity distributes with respect to described less two sides Central Symmetry
Sandwich block of the present invention is characterised in that, described decorative layer is provided with embossed layer.
Sandwich block of the present invention is characterised in that, described embossed layer outside is provided with waterproof coating.
Sandwich block of the present invention is characterised in that, described skeleton, core body and decorative layer are synchronously molded.
Sandwich block of the present invention is characterised in that, described skeleton, decorative layer are mainly by the following material that accounts for skeleton or decorative layer total weight percent: cement 25～45%, light aggregate 25～45%, basalt building stones 10～20%, mineral powder 8～15%, string 10～20 and Admixture 1～2 form.
Sandwich block of the present invention is characterised in that, described core body is mainly by the following material that accounts for core body total weight percent: cement 25～45%, Ultralight particulate material 25～45%, mineral powder 15～25% and blowing agent 5～15%.
The invention has the beneficial effects as follows: 1) adopt the compound sandwich structure of skeleton body and core body gummed, make the load-bearing area of building block and mortar glued joint area increase, the supporting capacity of building block and the adhesion strength of blockhouse improve, and the wall stability being built into is good; 2) fusion string in skeleton body material, makes skeleton body have good toughness, not easy to crack and generation micro-crack; 3) adopt light heat-insulating material to make core body, greatly alleviate on the one hand the proportion of whole building block, strengthen on the one hand effect of heat insulation, in addition the string and the light aggregate that in skeleton body material, add also have certain heat preservation and insulation, thereby make the body of wall overall weight that is built into lighter, heat-insulating property is superior; 4) location of building block when the groove in building block and boss are constructed constructability, guarantee the straight of metope, and building block is through accurate cutting and Milling Process, shape is regular, line face is straight, size accurate, it is tight to coordinate, make convenient and quick construction, be not subject to the impact of operator's level of skill, the quality stability of its body of building a wall improves greatly; 5) the high-quality paint film that the surfaces externally and internally of building block and notch position form through batch production application can effectively stop moisture to infiltrate, and guarantees the stable of body of wall moisture content; Protect basic material not to be subject to the erosion of Korrosionsmedium simultaneously, improve the durability of body of wall; 6) building block itself, with interior outside finish, can directly be built into body of wall attractive in appearance, has removed wall surfacing and the frock facility for wall surfacing from, can greatly reduce building costs; 7) structure of the solid atresia of building block and the acting in conjunction of groove shape structure can form the mortar die cavity of sealing, avoid the waste of mortar, simultaneously also can be by mortar joint stealth.
