It mainly useds to not accepting of the frame structure light plank building system to weigh an outside wall.The thin wall concrete rock cotton compound outside wall plank not only has a good heat preservation and insulate heat function, it winter the brick wall of the heat preservation equal to 370 mms, and more outside than the traditional material's wall plank weight lightly get many.But creation the craft is more complicated, the disadvantage applies at the expansion.
The concrete gathers a styrene compound outside wall plank
Concrete's gathering styrene's compound outside wall plank is accepted heavy layer(inside layer), 60 mms or 80 mm by the 70 mm thick reinforced concrete thick gather styrene plank of heat preservation layer(is intermediate) and 70 mm thick reinforced concrete decoration noodles layer(outside layer) compound but become.
This kind of compound outside wall plank can used to rounding of the steel or reinforced concrete frame structure, frame-anti- earthquake wall structure to protect an outside wall as well as be applied to other need to round the structure of protecting the outside wall.Its transmit heat coefficient on the average is only a 0.58 Ws|(㎡ ·K), invite an equal to 1 m thick piece of of heat preservation effect.But the noodles density is bigger, need appropriation to mourn machine gearing, disadvantage in expand applied current building industrialization.
The concrete inflates a pearl rock compound outside wall plank
The concrete inflates a pearl rock compound the outside wall plank is accepted a heavy layer by the reinforced concrete structure, inflate the pearl rock heat preservation layer and decoration noodles layer compound but become.The concrete inflates the compound outside wall plank thickness of pearl rock as 300 mms, among them accept heavy layer the thickness 150 mms, heat preservation layer the thickness 100 mms, decorate a noodles layer thickness 50 mms.
The steel wire net cement heat preservation material clips Xin plank
Steel wire net cement's clipping Xin plank is the Han that is cold the low carbon to pull out a steel wire in the factory to become a 3D space net, semi-processed goods in the center fill a light quality heat preservation Xin material(mainly use Zu burning gather a styrene foam of plank) but make into, at start construction the spot then is clipping Xin knothole two sides to spray to put on cement sand syrup or directly all prepare to make completion in the factory.
The kind of plank that clip Xin has weight lightly, strength Gao, quakeproof, heat preservation and heat insulation, separate a function good, fire prevention the function is good, wet anti-, the anti- jelly melt sex well, conveyance convenience, exhaust rarely, construction convenience economy, provide the building use the area.Ability according to design up of request construction become multiform wall body, even can in advance establish piping, electricity equipments, and doors and windows frame...etc. in the plank, then is producing inside the factory or construction the spot, again at the knothole steel wire up spreads to put on cement sand syrup, start construction simple, rapid, speed construction progress.But creation craft complications, the quality isn't even, not agree with to match to industrialize expansion an application.
The SP prepares hollow plank in response to the dint
SP's preparing is a kind of concrete that is new to prepare in response to the dint that adopts SPANCRETE company technique in the United States and equipments production to reach a piece in response to the dint hollow plank production technique.The plank adopts the flabby steel of Gao Qiang Di to wring line in order to prepare Jin in response to the dint lord, use special squeeze to model machine, at long the line set full general special match compare of dry the rigidity concrete carry on blunt press and squeeze once model, can produce various specification of prepare in response to the dint concrete plank material.
The product has surface neat and smooth, vivid size, across a degree big, the Gao He Zai Xiang, fire-proof extreme limit Gao, anti-vibration can like etc. advantage and production efficiency Gao, economical template, have never needed steam to protect and can fold to match characteristicses like production,etc.But the price is higher.
Add to annoy wall plank outside the concrete
Add to annoy wall plank outside the concrete is take cement, lime, and silica sand...etc. as main raw materials then a kind of light quality of the reinforcing bar net slice that requests to install to add a different amount processing to is through the antisepsis according to the structure is many new bore green environmental protection building wall planks outside the material.
The wall plank's Gao hole rate causes the density of material consumedly lower.The pore of the wall plank minuteness in the inner part formed the quiet air layer heat that let up material to lead a rate.Because the wall knothole hole leads greatly, having can saw, can nail and can drill and can glue knot etc. goodly can process function, easy to construction.The wall's plank has a good fire-proof function, higher hole rate to make material have to absorb advantages like a function,etc a little bit well at the same time and has already had more than 50 years of Euro-American flourishing national expansion application experience, the craft technique is mature.
The extrusion models the cement fiber wall plank(brief name ECP)
The extrusion models the cement fiber wall plank the main raw material is with the Huo quality material(is like natural stone powder, powder ash from stove, and tail mineral...etc.), cement, and fiber...etc. and model through a crowded Su of vacuum high pressure of hollow type plank material, then pass heat high pressure the steam protect but become of new building cement wall plank.The new cement plank passed to extrude to model a craft to make material, compare general the plank material strength is higher, the surface absorb water to lead low, separate one to contain better effect.
Its excellent function and abundant surface can not only used to construct outside wall adornment, but also contribute to the durable that raises an outside wall and present to enrich diverse outside wall effect.Can directly used to construct a wall body, reduce the construction work of several wall bodies preface, make the structure of wall body round to protect, decorate, heat preservation, separate a voice to carry out integral whole to turn.
From blessing Tai Gao Ke environmental protection science and technology(Shanghai) limited company provide of compound wall plank the related examination report express, extrude model the cement fiber wall plank to completely satisfy steel structure residence to have good heat preservation heat insulation towards supporting high strong and light quality of wall plank, and separate voice, watertightness, fire prevention, anti- crack and bear to wait the request that etc. synthesizes function.
Currently wall plank application study in existent problem
Assemble type economy energy compound wall plank because the its good characteristics is a particularly good heat preservation to insulate heat function but get application and expansion, and domestic and international to compound wall knothole use the function include anti- breeze, and anti- earthquake...etc. to once carry on a great deal of research and deduce a some particular theories and formula, but concerning compound the wall knothole grind a Gui achievement still not enough thorough and overall, the problem of main existence includes the following what time:
The great majority clip the Xin compound wall plank to use common concrete as a structure layer, but anticipate concrete as the research of the noodles layer with the light bone opposite less, be in need of the related compound wall plank point cultural heritage data that props up an anti- to bend to load a function related research, and at complete basic gearing of wall plank use the structure layer that process needs the basic mechanics index sign isn't explicit.
Light bone's anticipating concrete is economizing on energy to reunite to rise certain heat preservation heat insulation effect in the wall plank, but the light bone anticipates lowly to transmit heat function is with sacrifice its strength is antecedent of, therefore how maintain a light bone to anticipate concrete material good heat preservation function, further development raise a light bone to anticipate concrete strength to become the topic that needs to be studied and inquires into.
Economize on energy the heat preservation heat insulation that foundation and advantage of compound wall plank its expansion would are its oneself superiority function, but related hot work function the index sign and economy energy reunite the want for of the wall knothole node structure to grind Gui, therefore need to choose the node of a science gearing way, can promise to goodly protect to transmit heat function, and can attain oneself the basic mechanics function needed index sign.
Can know from the domestic and international research present condition, existing wall plank material if when converting to a 150 mm the wall is thick it transmits heat coefficient all mostly in the 1.3 Ws|(㎡ ·K)above, even could not reach some special norm in the region limit value requests, therefore have a necessity and develop 1 kind and economize on energy and reunite wall plank, it transmits heat coefficient to be lower than a 1.3 Ws|(㎡ ·K), provides design way of thinking for developing low plank transmitting heat the economy energy wall of coefficient.
Economize on energy to reunite wall plank concrete heat preservation economy energy effect in the engineering not explicit, economy energy compound wall plank's constructing in the concrete house can consume in its house and the economy energy leads of related data less, and transmit heat coefficient and building can consume of the relation want for of settle sex fixed amount relation.Consequently there being a necessity using homologously can consume an evaluation mechanism judgment economy energy compound wall knothole superiority.
Add to annoy wall plank outside the concrete to have the technique craft more mature and light quality, high strong, economy energy, fire prevention, soundproof etc. advantage, can process sex well, satisfy different weather area building economy energy of demand, according to design request some pieces to add to annoy a concrete wall plank to put together assemble type mold piece, handle making economy energy through the surface processing and the adornment the adornment integral whole disguise wall plank outside the go together with type, well carry out an article of standardize design, the factory turn a manufacturing, mechanization construction and consumedly raise engineering accuracy, decrease building garbage, practical attain "four sections one environmental protection", apply more wall plank currently of material.
Currently, domestic's assembling wall knothole development, production and application has already obtained a very big development out of the type.Along with compound the wall knothole is continuously thorough to study, wall plank design theory of perfect, the improvement, wall plank of the wall plank node pattern install technical of the use of perfect and new material, emollient push the compound wall plank is in the application in the engineering.Annoy by adding wall plank outside the concrete and extrusion to model the cement fiber wall plank to have light quality, high strong, economy energy, fire prevention, watertightness, the structure integral whole turn function, will become at present and from now on expand an applied direction.
