Preface

In the rapid progress that the current our country is being placed in town to turn, carry out "overall middle-class family" till 2020, the town turns level to attain 60% or so, the town population increases 300,000,000 around, the town turns the residence amount of constructions will at more long time inside keep higher level.Regret of BE, at present these construction achievement big part is with traditional of high devotion, Gao can consume, high pollution for the price obtain.Push forward the building industrialization, residence building industry to turn, is carry out residence construction method from thick put type to intensive type change, exaltation the residence quality and economy residence can consume of the major act is to promise that the building industry can keep on the important path of development, to our country economy and society development have very and profound meaning.


On January 1, 2013, office in State Department forwarded development reform Wei and the green building of the housing city country construction department to act a project and definitely put forward to list as ten big important tasks:"expansion building industrialization, development green building".Building industrialization and residence industry turn and the town turns construction to request to actively expands assemble to turn a construction.Round to protect structure in, investigating the key index sign of constructing the industrialization level is the assemble of outside wall to turn degree.Expand the application assemble type light wall plank outside the quality concrete industry policy according to national green building and building economy energy, is construct a profession realization can keep on to develop strategic of important contents.

In 2019 lately assemble type the building is compound outside wall knothole to develop present condition and trend

The abroad assembles type compound the wall plank study present condition

Abroad of assemble type compound wall plank mainly is after 70 years development get up, the light quality wall plank of the United States regards various gypsum plank as principle, with species many, whole specification, the production mechanize degree Gao but Zhao said, the yearly production is 2,000,000,000 square meters, reside a world first;Japanese asbestos cement plank, steam to press the production that the laurel Han Ban, glass fiber strengthens cement plank(GRC plank) to reside leading level in the world;England with have no asbestos laurel Han Ban is lord;Germany and Finland regards hollow light quality concrete wall plank production as principle.The abroad mainly formed Frenchly Rong CsatelEiffle for long time the FCIS wall system of the housing complex the all and Italian BSAIS industrialization construct the PCa wall plank system of outside wall system, high Japanese the steel structure residence wall body adoption.


The local wall knothole outside the assemble type develops present condition and function comparison

Constructing the outside wall is mainly to architecturally constitute part, its structure and the material used influences a building to consume index sign and the indoor to live a comfort index.Construct in the residence in, rounding to protect structure can consume in:The outside wall can have to 34%, the stairs partition wall is about 11%.Development Gao quality the outside wall reunite heat preservation wall the plank carry out residence industry to turn and expand to economize on energy architectural important shortcut.The production of the wall plank wall body material of some flourishing nations at it national wall body material total yield in the proportion had have already been up to 60%, while the our country only has 3%.Wall structure outside the building, the our country is strongly encouraging to develop a green building materials, strongly expand various don't  glue soil brick of, the wall material of light and big size, raise the rate of production of the green outside wall heat preservation material of extensive use further at the same time.


The domestic is the main wall plank category of outside assemble type wall plank use to have currently:Accept a heavy concrete rock cotton compound outside wall plank, thin wall concrete rock cotton compound the outside wall plank, concrete gather a styrene compound outside wall plank, concrete pearl rock compound the outside wall plank, the steel wire net cement heat preservation material clip Xin plank and SP to prepare the hollow plank is in response to the dint, add to annoy wall plank outside the concrete and vacuum to squeeze to model fiber cement plank.(brief name ECP)

In 2019 lately assemble type the building is compound outside wall knothole to develop present condition and trend

Accept a heavy concrete rock the cotton is compound outside wall plank

Accept heavy concrete rock cotton to reunite the outside wall plank is accepted by the reinforced concrete structure heavy layer, the rock cotton heat preservation layer and decoration noodles layer compound but become.Accept heavy concrete rock cotton to reunite outside wall plank thickness is 250 mms, among them, the reinforced concrete structure accepts heavy layer the thickness 150 mms, the rock cotton heat preservation layer thickness 50 mms, decorate noodles layer thickness 50 mms.


Mix the wall plank outside the concrete of wall body or Peng bead, pumice and pottery grain with traditional brick and compare, the kind of compound outside wall plank in addition to have orientation and accept importance in addition to the mechanics function begged, also match a public building of 枟 and economize on energy and design standard 枠 as to it's heat preservation, insulate heat the request of function, have strength Gao, heat preservation heat insulation function good, construction convenience etc. characteristics, in winter heat preservation effect equal to thickness is the brick wall with 490 mms, hot the stability also surpass the thickness as the brick wall with 370 mms.But noodles density more big, it is lower to install an efficiency, the disadvantage applies at the expansion.


The thin wall concrete rock cotton reunites outside wall plank


Thin wall concrete rock cotton compound outside wall plank from the reinforced concrete structure layer(inside layer), the rock cotton heat preservation layer(is intermediate) decorate a noodles layer(outside layer) with concrete compound but become of not accept heavy the type is compound outside wall plank, wall plank thickness is 150 mms.


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.

In 2019 lately assemble type the building is compound outside wall knothole to develop present condition and trend

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.

In 2019 lately assemble type the building is compound outside wall knothole to develop present condition and trend


Conclusion
