The stone material plays the part of the board, by it natural, artistic, magnificent, noble and so on characteristics, is day by day widespread in the construction decorations application, presents by indoor to outdoor, by the low altitude to the upper air, by the scrap the tendency which develops to the bulk. Now in ours construction, everywhere may see with the stone material decorations wall surface, the ground, the floor and so on, the stone material by its unique natural style, the lofty sharp contour, entrusts with building more modernities and the artistic feeling, becomes the urban architecture to march into one of modernized important symbols.

    Along with stone material application day by day widespread, the people also day by day take seriously to the stone material projects security and the quality. However, because many people are really few to the stone material characteristic understanding, thus has had many misunderstanding to the stone material, in this has the necessity to make one to the stone material in construction science reasonable application to clean up.

     One of doubts: The stone material will be very heavy, installs will become the safe hidden danger in the upper air?

    The high-level for decorative or ornamental purpos stone material generally wants heavy 3 times compared to the glass, hundred and thousand of flagstones paste in the outer wall, the people often thought that the stone material curtain wall project high-level will have the very big security hidden danger particularly, worried that can have the stone “to drop from the clouds” poses the personal safety threat.

     Dispelling doubt: Actually, constructs the stone material which in the outer wall uses is strictly according to Metal And Stone material Curtain wall Engineering technology Standard (JGJ133-2001) request implementation. Technically looked that the stone material hangs the construction is dry supposes the main working point in the main body structure, hangs through the metal to fix the stone material in the building, forms the stone material decoration curtain wall. The stone material hangs dry principal advantage: First, enhanced the security and the durability, may avoid pasting the plate spatial drum which, the dehiscence effectively in the craft appears, to fall off wet and so on phenomena; Second, maintains the curtain wall clean artistic, avoids pan-white, phenomena and so on color deterioration; Third, the improvement execution conditions, reduced the labor intensity, sped up the progress of works. Looked from the material that the stone material decorations material is guaranteed the project quality the key, besides the stone material, mainly has the steel (aluminum) the framework material, to hang the board, the suspension hook, the structure rubber and the seal bears the period of five days rubber and so on. Selects moldings and so on aluminum material, steel products, must meet the national code requirement. The aluminum material surfaces galvanizing must meet the national AAA5 level above requirements, the steel products must certainly carry on pot galvanize or carry on processing with other anticorrosive material, guaranteed that it does not have the corrosion. The connection hangs the board to use 3 millimeter above stainless steel plates or 4 millimeters above aluminum sheets. Compares with present widespread uses glass curtain wall, the stone material curtain walls security is actually higher. With uses the structure rubber fixed glass curtain wall to compare, connects the flagstone with the steel work to be much more reliable.

     Second doubts: The stone material is polluted easily and “the pathological change”, is not suitable uses?

     After many stone material decoration project construction, produces the stone material “the pathological change”, like the water stain, spits yellow, the pan-alkali and so on, causes the people to think that the stone material is not good serves, the quality has the question, thus has the contradiction psychology, thought that the stone material the use is not convenient.

    Dispelling doubt: Actually, these questions are not difficult to solve; first, before carrying on stone material leaving the plant protection processing. The natural stone material is the mineral substance, the internal pore is thick, each kind of source of pollution like rain water, the acid and alkali, the greasy dirt and so on will permeate will form “the pathological change”, therefore should coat the stone material protective agent before stone material gauge frame leaving the plant, should better be the permeable protective agent (has resolver and river character two kinds), will form a protective barrier, will prevent external pollution permeating, will prevent the stone material interior and the first floor pollution seeps out, will thus achieve maintains the stone material original appearance, extension stone material service life goal. Second, the stone material later period maintenance is also very important. In order to maintain the stone material sharp, the maintenance devotedly is necessary, it including the daily clean, the pollution elimination and the polishing polishes three aspects. Daily clean available clear water or some neutral cleansing agent, after the clean, must dry the surface, avoids the residual moisture content causing the pollution. The daily clean can only eliminate some superficial the dust and the dirt, if meets some special pollution, like the plant pigment pollution, the greasy dirt, the rusty stain and so on, must use the special cleansing agent to eliminate. If the surface were not has the gloss very much or has the scratch even to tarnish, must carry on the polishing or the polish to the stone material. The polishing has the special liquid medicines, after smudging, increases brightness with the buffing machine; The polish must regard the stone material the extent of damage to decide, light carries on polishing with the manual coordinate liquid medicines, heavy needs the dresser coordination special-purpose medicament, may make the stone material to restore the original gloss.

    In brief, undergoes the reasonable design, the construction, the use, can control the stone material project well the quality and the security. The stone material takes one natural plastic very high construction finishing materials, to enhances buildings personal status, to increase buildings connotation, is other building material incomparable.
