Description
Technical field
The utility model relates to building material technical field, is specifically related to a kind of EPS-foam cement composite self-insulation L shape wall corner building block.
Background technology
Along with the energy, the increasingly sharpening of crisis of resource, actively must advocate green building, the facade lighting of strengthening building energy conservation.Adopt the various materials for wall with heat insulation function, not only can save ample resources, can also energy consumption be reduced, reduce environment pollution.
In this context, external thermal insulation system obtains and develops on an unprecedented scale.But through enforcement in recent years and application, find the energy-conservation way wrapped to body of wall, fundamentally do not solve the power saving of construction wall space enclosing structure, and bring the various problems such as safety, construction, cost.
Novel from energy-conservation walling and heat insulation system thereof because of its obvious energy-saving effect, represent the direction of wall reform development, more and more get the nod.
Foam cement is mechanically fully foamed by blowing agent by the foamed system of foaming machine, and by the cementitious material such as foam and cement slurry Homogeneous phase mixing, then cast-in-place construction or mould molding is carried out by the pumping system of foaming machine, a kind of lightweight fireproof insulating material containing a large amount of sealed porosity formed through natural curing, its advantage is that stable performance, coefficient of deformation are little, not only fire protection flame retarding but also anti-aging, application life is relatively long, difficulty of construction is relatively little, engineering cost is relatively low, can cycling and reutilization.But foam cement is due to the limitation in its formula and technical matters, and most of article construction is single, and stable not, coefficient of thermal conductivity is higher, and heat-insulating property is not enough, and intensity is low, and pliability is poor, frangible rapid wear.
Polystyrene foam (Expanded Polystyrene is called for short EPS) is a kind of light type high-molecule polymer.Organic EPS heat insulating material have lightweight, pliability good, workability good, not easily broken, compactness is high, the advantage of good effect of heat insulation, shortcoming is that fire safety performance is not enough, coefficient of deformation is large, not ageing-resistant, in practice of construction application, there is certain difficulty.
How EPS is combined with foam cement technology, overcome respective defect, comprehensively play both advantage, prepare a kind of Novel compound self heat-insulation building block, be the research topic that building material industry one is brand-new.
The existing EPS building block manufactured that combines with foam cement mainly contains two kinds of forms:
Be a composite heat insulation block for EPS-foam cement sandwich structure, the centre position of this building block is EPS warming plate, and both sides are foam cement; During preparation, first insert EPS warming plate in a mold, then in mould remaining space pouring foaming cement slurry, become insulation blocks through sawing after maintenance.
Another kind utilizes Making mold to become the middle foam cement building block having various hole, then EPS plate is cut into the shape matched with the hole of foam cement building block, inserts in the hole, form heat insulating composite building block.
These two kinds of structures, all must use particular manufacturing craft during the first manufacture foam cement building block, cost of production is higher, and the second heat insulation effect is also as one wishes not to the utmost, has much room for improvement, and still needs secondary isothermal holding as during outer wall body.
