Description

The assembling body of wall that a kind of support, the formula that reclines are installed
Technical field
The assembling body of wall that a kind of construction wall in the present invention relates to build, particularly a kind of support, the formula that reclines are installed.
Background technology
The current problem that exists with prefabricated panel installation assembling body of wall mainly is:
1, the power saving of construction wall technology is not solved all the time.
Once the issue report showed that the emission reduction effect that green building and building energy conservation are contained was greater than all greenhouse gas emissions that require in the Kyoto Protocol in March, 2007 in the United Nations, was equivalent to three times of the predetermined CER of Kyoto Protocol.The building energy conservation situation directly influences global warming, and south poles is melted, and melt on the iceberg, sea level rise, the animals and plants extinction.
The report that the World Bank delivers is warned: " multirow moves unless take more to climate warming, otherwise global temperatures will rise four degrees centigrade again in the end of this century.The danger of liter, food shortage, extreme weather conditions on the global plane of bordering on the sea, this will make that coastal cities and the poor are in the face of catastrophic effect ".The World Bank on November 18th, 2012, the issue report claimed, climate change is one of ultimate challenge of facing of global evolution, is descendants's meter, and various countries should undertake moral duty separately, the minimizing greenhouse gas emission of taking action conscientiously.……
Much publicize the data of heat insulating materials now, how good the heat insulating material insulation that all publicizes oneself is, how low wall heat transfer coefficient can reach, but this is the main wall body heat transferring coefficient that does not contain heat bridges such as window, balcony slab in fact, rather than mean thermal transmittance, and our the final wall heat transfer coefficient that requires is the mean thermal transmittance that contains heat bridge.
Contain the influence of heat bridges such as window, balcony slab interior existing, China heating area, really reaching body of wall mean thermal transmittance K is 0.5w/m 2.k Yi Xia building is few, heating phase body of wall total heat consumption=24K * days of heating period (be 170 days as the Harbin City) * indoor and outdoor mean temperature difference in winter (stipulating that the Harbin City is 26.5 degree) * wall area.As seen, wall heat transfer coefficient is very big to the influence of winter heating heat consumption.Same thermal transmittance is also very big to the energy consumption influence of refrigeration air-conditioner in summer, and southern non-heating region body of wall mean thermal transmittance K now is about 1w/m 2Even more .k.
Some prefabricated panels are provided with topping at the termination side; mostly these toppings are cement mortar or add light weight sand mortar or the magnesia cement mortar cover of light material; its coefficient of thermal conductivity forms heat bridge much larger than the prefabricated panel inner thermal insulating layer, causes the prefabricated panel heat bridge too many.Also have wallboard termination gaping of joints, ventilative problem, in addition winter along the seam crossing dewfall, mouldy, become mildewed, the phenomenon of wood flooring warpage takes place.Though be heat-insulation wall plate, because of ventilative, energy-saving heat preserving is also bad.How to pass prefabricated panel with reinforcing bar as the crab-bolt level during installation, prefabricated panel and beam column are fixed, conduct heat again.
The frame beam column area accounts for exterior wall area 25～40%, and the wallboard of building filled wall or installation in framework by laying bricks or stones is installed in the framework hole more, and there are thinner masonry or wallboard in the frame beam column outside, and the insulation of beam column place is weak, forms heat bridge;
Also have the plug-in body of wall of (building standard design atlas " precast concrete out-hung panel " 08SJ110-2,08SG333), because interior siphonal lobe concrete is too heavy, to stressed unfavorable, insulation layer thickness is restricted, and these are all very big to the influence of body of wall energy-saving heat preserving.
The heat bridge of existing body of wall technology is all too many: different structure form, different decoration, different energy-saving wall technology, different balcony heat preservation technologies, (there is air layer at the place as the sandwich heat preserving wall body inner thermal insulating layer, forms cross-ventilation to add a large amount of door and window heat bridges, steel tie heat bridge, cross-ventilated heat bridge.), these heat bridges are a lot, and the heat bridge amount of calculation is big, and it is very difficult that the designer calculates heat bridge, causes the body of wall mean thermal transmittance not have transparency, often misled building energy conservation.
2, the reinforcing bar or the crab-bolt corrosion that are connected with major structure of construction of the assembling body of wall formed of prefabricated panel, socket as setting that reinforcing bar passes insulation layer and major structure of construction sockets, and steelframe is set in prefabricated panel, socket reinforcing bar or diagonal reinforcement or oblique cutting steel wire and pass insulation layer inside and outside reinforcing bar is socketed.Reinforcing bar when not having the protection of strong concrete alkaline environment, easy-to-rust, durability is bad, common engineering be unwilling to be used stainless steel rebar, with galvanizing steel may be all seldom.Prefabricated panel is connected ironware with major structure of construction solder joint does not have alkaline cement mortar or concrete protection, is easy to corrosion, influences safety, the durability of assembling body of wall, and is unfavorable to social sustainable development.
What 3, have arranges the prefabricated panel that lightgage steel joist is installed light-duty complex heat-preservation template, and prefabricated panel and keel are fixed, and what is the anchored force of lightgage steel joist and flooring up and down? be unknown number, this wallboard bears horizontal loading and can not design by ultimate limit state.The assembling body of wall of the present type composite insulation boards of not taking a favourable turn can satisfy regulation and the case history of ultimate limit state design, poor stability.Follow closely sheet iron at the dry wall edges of boards in addition, again with iron sheet nail connection prefabricated panel on major structure of construction, is the pulling force that this connection can be born much? it also is unknown number, can only be used for the little low-rise building of wind-force, and the corrosion resistance of tie point is also bad, at first corrode at the ailing place, influences durability.And wallboard divide is done inside and outside two-layer and keel fixed installation, and not only beam column outside heat bridge is many, and its ratio of rigidity closes two-layer wallboard and do one deck precast wall body and install very differently, and wallboard is stressed indeterminate, and increases prefabricated and installation cost.
The prefabricated panel template consumption of the assembling body of wall that 4, has is big, needs great amount of investment, adds a large amount of investments in land, because increasing considerably cost, makes that carrying out the assembling body of wall is difficult to carry out.
5, China and global earthquakes are multiple, and China's highrise building ratio is very big.Current filled wall is stressed fuzzy to the major structure of construction influence, is difficult to calculate, and is unfavorable for guaranteeing building aseismicity safety, is unfavorable for the anti-sidesway safety of highrise building.The existing assembling wall structure that has the adaptation major structure of construction to be out of shape is too complicated, cost is high.As:
1), by Beijing City Building Design Inst. the connection of the Japanese architecture wallboard " structure ", a literary composition as seen, the anti-seismic construction of the assembling body of wall of Japanese slip is complexity too;
2), also as building standard design atlas " precast concrete out-hung panel " 08SJ110-2,08SG333, wherein the 16th, 17,32～35,44～47 pages is the exterior wall concrete link plate, be whole concrete panel of slip, structure is complicated too, processing prefabricated panel difficulty is big, installation difficulty is big, amount of reinforcement is big, installed part quantity is many, the cost height, must be prefabricated on platform, occupied ground is big, the land resources that waste is valuable, only be used in a few high-end engineering at present and suffered, be unfavorable for that the assembling body of wall is popularized and assurance building aseismicity safety and the anti-sidesway safety of highrise building.
6, in the highrise building curtain wall decoration being installed, when the curtain wall decoration particularly is installed, under wind load and horizontal earthquake action, when the major structure of construction interlayer is subjected to displacement the angle, the curtain wall squeeze and destroy being taken place easily, is reluctant problem in installing.
Durability, the safety of the problems referred to above influence building, influence building energy conservation and reduce discharging, influence reduces global greenhouse gas emission, influences the anti-sidesway safety of building aseismicity and highrise building, influences the housing industrialization process.For addressing the above problem, convenient construction reduces cost, the assembling body of wall that the present invention proposes a kind of support, the formula that reclines is installed.

Two kinds of assembling bodies of wall of the present invention can fit applications in the different parts of building.
The present invention is with the key difference technical characterictic of public technology:
1, following 4 technical characterictics are arranged is that current assembling body of wall technology is unexistent to the assembling body of wall of embodiment of the present invention one:
1) at major structure of construction the structure supporting parts is set, support is at the outside assembling body of wall of installing of major structure of construction, and structure supporting parts (mainly being that concrete cornices) arranges or the local interruption setting continuously.
2), the structure supporting parts is interrupted when arranging, the termination of prefabricated panel is provided with breach, the position of breach is with to be interrupted the structure supporting parts that arranges corresponding, this is convenient to be template outside the beam with the prefabricated panel, concreting cornices.
When 3), prefabricated panel is light-duty composite thermo-insulating wall board, the various materials of light-duty composite thermo-insulating wall board connect as one, form the primary structure member of an integral body, the assembling body of wall of disclosed light prefabricated composite thermo-insulating wall board can not form the primary structure member of an integral body.
4), assembling body of wall topping satisfies the fire endurance requirement, the opening protection layer satisfies the fire endurance requirement, disclosed assembling body of wall technology does not have and proposes this requirement.
2, embodiment of the present invention seven except have above-mentioned 4 technical characterictics be current assembling body of wall technology unexistent, it is that current assembling body of wall technology is unexistent that following technical characterictic is arranged again: the assembling body of wall of embodiment seven is not plug-in body of wall, one end of assembling body of wall is fixed end, and the other end is the slippage end.
The present invention is not only the body of wall of slip, and still is at the assembling formula body of wall of three direction dampings.This makes the slip assembling body of wall contrast of the assembling wall structure of slip of the present invention and the described Japan of background technology and China's structure atlas, its structure, install all too simple.It is unrestricted that assembling body of wall of the present invention increases core layer thickness, easily realizes the overcast hot coefficient of body of wall.
The slip body of wall of the described Japan of background technology or China is out-hung panel.Japan is plug-in with shaped steel; China's atlas body of wall is plug-in with the bracket that is installed on the wallboard; or the shaped steel that is installed in the concrete edges of boards is connected plug-in with wallboard; see the 33rd page of atlas; bracket had both been born the weight of assembling body of wall; slip property is born in bracket the inner mounting slip spare again; and if plug-in with shaped steel; with the local increase thickness that needs of the internal lobe concrete of shaped steel connecting portion; reduce insulation layer thickness, these two kinds of installation constitutions are all very complicated, and connected node is stressed big; require installation accuracy too high, the construction trouble.The assembling wall insulating layer of atlas is too thick not all right because more unfavorable to structure stress, structure design is more complicated.
3, embodiment of the present invention two, eight is that current various prefabricated panel mounting technique is unexistent with assembling body of wall and being connected of major structure of construction.Because embodiment one, seven has been installed in prefabricated panel on the structure supporting parts, embodiment two, eight can be fixed prefabricated panel and major structure of construction fast with crab-bolt again.Needn't be provided with diagonal brace after crab-bolt is fixing and just can guarantee the prefabricated panel stability of installing, construction install convenience is installed reliably, and its safety is not only considerably beyond current various filled walls of building by laying bricks or stones, also surpass current various assembling bodies of wall, this is that the existing prefabricated panel technology of installing is unexistent.
4, install in the embodiment three, nine being configured with of reinforcing bar following 2 different with existing assembling body of wall technology:
1), longitudinal reinforcement and main tie point are positioned at the vertical joint place of prefabricated panel, or the prefabricated batten place between prefabricated panel, the force direction that is subjected to that the main tie point that longitudinal reinforcement is connected with major structure of construction transmits power is the direction of reinforcing bar along the longitudinal, stressed clear and definite, stressed good, easy for installation, rolled steel dosage is few.
5, embodiment of the present invention four, ten anticorrosive measure are that existing assembling body of wall technology is unexistent.
1), the present invention is in textural easy construction with assurance supporting, reinforcing bar and tie point protective layer thickness; longitudinal reinforcement is installed in the vertical joint place of prefabricated panel; or be installed in prefabricated batten place between the prefabricated panel; make things convenient for reinforcing bar localised protection layer to thicken, thereby make the anticorrosive measure that guarantees thickness of protection tier in the embodiment four, ten to realize.
2), proposed near supporting, reinforcing bar and tie point with cement polymer elasticity mortar or cement polymer elastic concrete, or also add the silicon ash, be that prior art is unexistent.
Near the reinforcing bar or ironware that prefabricated panel is connected with major structure of construction, should not smear conventional cement mortar, because the easy dry shrinkage and cracking of a spot of conventional cement mortar, reinforcing bar or tie point are perishable.And smear cement polymer mortar or cement polymer concrete, particularly cement polymer elastic mortar or or the cement polymer elastic concrete can protect tie point to avoid corrosion effectively.
Cement polymer elastic mortar or cement polymer elastic concrete good springiness, tensile strength height, to adapt to the distortion crack resistance good, and with conventional cement mortar or concrete ratio, anti-carbonization, corrosion resistance are good.If add the silicon ash again, more increase anti-corrosion capability.The silicon ash can form the C-S-H gel in reaction; gel-filled in the hole of hydrated cementitious; increase the topping compactness; significantly reduced the cement space; the intrusion and the corrosiveness that have stoped acid ion effectively; significant prolongation concrete application life, particularly pollute under the adverse circumstances such as erosion, sulfate attack, high humility at villaumite, the durability of concrete is doubled even several times.So to the protection reinforcing bar, it is favourable to prevent that burn into from increasing durable years, satisfies the anticorrosion requirement easily under thinner protective layer thickness.
Technique effect of the present invention:
1, assembling wall heat transfer coefficient of the present invention has transparency, during hole heat insulation break bridge structure, reduce energy consumption 50～70% approximately than current energy-saving wall, promote body of wall energy-saving heat preserving level significantly, reduce construction investment significantly, help the whole world to reduce greenhouse gas emission.This has following reason:
1) assembling body of wall of the present invention is at prefabricated panel, purposes was the most extensive when prefabricated batten was light prefabricated warming plate.Stressed unfavorable to building because of heavy wallboard, can not produce fast with special equipment, take a large amount of land resources, the template investment is big, manpower consumption is many, the cost height.
There is not the slit between the sandwich layer between the sandwich layer of light prefabricated heat-insulation wall plate and the assembling body of wall, the coefficient of thermal conductivity that the external wall outer insulation slit increases does not take place, for example consider to socket the heat transfer that steel wire increases, when 1 reinforcing bar is installed at the place, slit, sandwich layer is the desirable 0.042w/m.k of the revised coefficient of thermal conductivity of EPS plate, and external wall outer insulation is because of the influence in slit, and the desirable 0.05w/m.k of the revised coefficient of thermal conductivity of EPS plate increases energy-saving heat preserving effect 20%.
2) the present invention has eliminated beam column heat bridge, hole heat bridge, balcony slab heat bridge, the heat bridge that only cornices at last, but and the local interruption setting of cornicing.The assembling body of wall that common support, the formula that reclines are installed is interrupted setting and cornices, and seam is installed 1 and 2 reinforcing bars, only increases body of wall mean thermal transmittance 0.02w/m respectively approximately 2.k, 0.04w/m 2..The thermal transmittance of table 4 is the thermal transmittances that comprise various heat bridges, and it is unrestricted to increase core layer thickness, and the assembling body of wall easily reaches low heat transfer coefficient, as follows face table 2～table 4 calculated data.So with current heating area and non-heating region energy-saving wall thermal transmittance present situation ratio, can reduce heat waste 50～70% approximately, promote body of wall energy-saving heat preserving level significantly.It is many at position heat bridges such as beam columns to have solved the described current frame construction of background technology, influences body of wall energy-saving heat preserving effect problem.
Why has generality by hole heat insulation break bridge structure? 1), to plaster in the hole increase a lot of wet trades, increases labour cost, low in hole EPS plate brushing fire prevention glue, the fireproof paint cost of plastering than at the hole; 2), the hole floated coat hidden on the indoor and outdoor trimming bar the pre-buried steel disc that is used for installing window, is inconvenient to install window; 3), the hole formation heat bridge of plastering, increase the about 0.15～0.2w/m of body of wall mean thermal transmittance 2.k, very big to the energy-saving heat preserving influence.So regardless of to the energy-conservation requirement of body of wall, all recommend the hole to take heat insulation break bridge structure.
Applicant was once carried out economic analysis to low-energy building, reach a conclusion in " low-energy building is to reducing the meaning of social infrastructure construction investment " (being published in " China Reconstructs's newspaper " on February 16th, 2,006 12 editions) literary composition: low-energy building can reduce the construction investment of earth source heat pump equipment and solar energy heat collection equipment significantly, and the engineering cost of earth source heat pump heating and central heating supply are approached, considering does not need to establish in addition chiller plant investment in summer, also reduces construction investment.Table 1 is applicant to Beijing, Shenyang, Harbin when the different building energy saving rate, presses the power distributing amount index that electric heating calculates a theoretical electricity consumption value of heating phase heating and needs.
In the low-energy building of heating phase weak point, central heating supply needs the outdoor pipe network of great amount of investment, boiler room, does not calculate very much; And with electric heating (as using heating cable), adopt the electric load tuner, and need not increase power distributing amount, the expense of increasing capacity that do not increase electric power, can reduce construction investment significantly.By table 1 heating theoretical value as seen, the electric heating expense of Beijing area energy-conservation 75% is well below the central heating supply expense; If use earth source heat pump, its equipment operation power consumption only is 1/4 of electric heating, contains management fee interior, possible heating cost be electric heating take 50%, namely only 25% of current approximately central heating supply expense just much of that? this will become the investor's attraction.More than analyzing is in order to illustrate: the present invention is in the technical possibility of building low-energy building that provides of body of wall, and because body of wall reaches low heat transfer coefficient easily, the present invention can reduce engineering significantly for ensureing the investment of building thermal environments.
The different energy conservation standard electric heating of table 1 theoretical value, power distributing amount index (building shape coefficient about 0.22～0.23)

Figure BSA00000820441700091
By the thermal transmittance of table 4 summary sheet and strengths and weaknesses analysis as seen, be interrupted to arrange that the structure supporting parts---concrete cornices, the outer end of cornicing is not incubated the superiority maximum: convenient construction, the convenient seam crossing reinforcing bar of installing, make things convenient for the mounting slip member, can satisfy body of wall low heat transfer coefficient requirement etc.The balcony fence of Figure 20 can reach the thermal transmittance identical with the main wall body, and the heat bridge of assembling body of wall only is to be interrupted the structure supporting parts heat bridge that arranges.Though civilian construction have balcony, also satisfy the requirement of low-energy building easily, it is big that building energy conservation is reduced discharging meaning, and reduce the cost that satisfies the building thermal environments investment significantly.
2, assembling wall structure of the present invention is simple, in light weight, installation rate is fast, easy construction, steel using amount are few, safety and good endurance, can satisfy the designing requirement of structural limits state, not only the assembling wall cost is low, and reduce the major structure of construction cost and reduce building thermal environments cost, wide application of the present invention.
Structure and standard construction atlas " precast concrete out-hung panel " 08SJ110-2,08SG333 contrast with embodiment of the present invention seven～11, assembling wall structure of the present invention is too simpler than standard construction atlas, steel using amount (comprising that alkaline-resisting screen cloth is converted to gauze wire cloth) is about 20% of the 45th page of quantity of reinforcement of atlas generally speaking, but its function is not less than the performance of standard construction atlas assembling body of wall: be can contain be out of shape between the post of major structure of construction and the beam, slip the assembling body of wall, and also have cushioning effect in three directions.
Why is the standard collective drawings steel using amount big? because the prefabricated panel of atlas is not the combined wall board that can form whole primary structure member, inside and outside leaf concrete slab and centre accompany insulation layer, between not bonding connection, be to rely on the oblique rollering steel muscle that interior siphonal lobe concrete slab is socketed connection mutually, between the layers of material changing of the relative positions can take place, therefore can not think that inside and outside leaf concrete slab and insulation layer form the integrated member of common stress deformation by theory of mechanics of materials.Atlas wallboard inboard is stressed wallboard; thickness is for being not less than the 150mm concrete; the outside is the thick concrete of 50mm; weight is big, is about 4 times of the conventional gross thickness of the interior external protection of the present invention, is 4 times of the present invention by the seismic Calculation geological process therefore; and the cross section bending resistance arm of force of internal lobe concrete slab is little; quantity of reinforcement is just much bigger than the present invention naturally, in the calculating is its control action of geological process, and is very unfavorable to structural calculation.Illustrate: if the standard construction atlas need be provided, ask auditor and applicant to contact, applicant is issued the auditor with the atlas of downloading.
The assembling body of wall of this standard construction atlas must be prefabricated on platform, and occupied ground is big, China's land resources anxiety, and the construction amount is too big, and prefabricated panel is all prefabricated on platform to be infeasible.And the present invention is when adopting light prefabricated heat-insulation wall plate, and existing mechanical equipment can reach approximately produces prefabricated panel 1000～2000m every day 2, the health of putting on the shelf, occupied ground is few, and the amount of labour used is few, and prefabricated cost is low.
When the composite thermo-insulating wall board that the present invention adopts forms the primary structure member of an integral body, the cross section bending resistance arm of force is big, and sandwich layer thickens unrestricted, except door and window hole need be with the reinforcing bar bending resistance, in most cases, just the bending resistance designing requirement be can satisfy with netted tensile materials, reinforcing bar and netted tensile materials contained interior, steel using amount is few, save great deal of steel, main tie point quantity is few, easy for installation, stressed clear and definite, and safety of structure is good; When the needs encryption arranged reinforcing bar, the body of wall that can satisfy the hurricane typhoon region bore the horizontal loading requirement, and this existing assembling body of wall technology is not accomplished.
Assembling body of wall of the present invention is 25% of structure atlas wall weight approximately, reduces geological process significantly, is conducive to the major structure of construction antidetonation.Assembling body of wall of the present invention not only self cost is low, because of in light weight, also reduce the major structure of construction cost, particularly reduce earthquake zone major structure of construction cost significantly, as described above, also reduce the building thermal environments construction investment, wide application of the present invention has important energy saving and reduces discharging meaning and building aseismicity meaning.
Whether adopt slip assembling body of wall to need not definite on an equal basis according to local seismic fortification intensity, building height, wind reference pressure, building importance rate.
3, embodiment of the present invention seven has three directions the geological process of alleviating is arranged, and increases quake-resistant safety.
4, assembling body of wall of the present invention is installed hanger for exterior wall condition is provided, as anti-theft fence, sunbreaker, curtain wall decoration be installed, to such an extent as to billboard, solar opto-electronic board carry out exterior wall greening etc., the exterior wall hanger can be directly be connected with steel plate or block shaped steel on the prefabricated panel longitudinal reinforcement, the assembling body of wall that needn't pass is connected with major structure of construction, squeeze and destroy can not take place in curtain wall, both safety, reduce heat bridge again, energy-conservation, this is that disclosed assembling body of wall technology is not accomplished.When the present invention was used for curtain wall decoration, the shaped steel specification of curtain skeleton reduced significantly, and steel consumption is few.
5, assembling wall structure of the present invention can satisfy the multiple facade modeling requirement that has ordinary rectangular or arc-shaped window, horizontal townhouse window, vertical bar window simultaneously.
The invention solves the problem that the described current assembling body of wall of background technology exists, simple structure of the present invention, technical know-how is perfect, technical measures are comparatively tight, and safety is good, easy construction, installation rate are fast; The present invention can promote the energy-conservation level of body of wall significantly, and favourable building energy conservation reduces discharging, reduces the building greenhouse gas emission, adapts to the low-carbon (LC) social situations, the control global warming; The present invention is the optimization to the assembling wall structure: use a spot of steel, satisfy the designing requirement of structural limits state, and favourable building aseismicity, favourable wall reform, be conducive to advance housing industrialization; Assembling body of wall of the present invention self cost is low, and reduces major structure of construction investment and building thermal environments investment, reduces total investment of engineering, wide application significantly, has great social significance.

Other as should satisfy the alkaline-resisting strength retention ratio of standard-required with alkaline-resisting screen cloth, also as using the after heat galvanized electric welded mesh, can protect solder joint by galvanizing, and is anticorrosion good.
Embodiment 11: the difference of one of present embodiment and embodiment seven～ten is that present embodiment also increases following fire protection construction measure, selects for use one of them or collocation to select for use as required, is the 3rd fire protection construction measure of assembling body of wall:
1), the topping on the insulation bar installed of the doorframe and window frame outside satisfies fire endurance and requires (window perimeter walls bulk diffusion in the time of can reducing fire and take place);
2), in the assembling body of wall, increase fire barrier 11, the fire endurance requirement is satisfied in fire barrier 11; As fire barrier 11 for not firing or difficult combustion heat insulating material, fireproof paint, fire prevention glue, cement mortar or concrete, or for the concrete of the cement mortar of modification or modification etc.; Fire barrier 11 be provided with following 2 kinds of modes, according to using needs to select: 1., at interlayer horizontal fire barrier 11-1 is set; 2., in prefabricated panel (15) vertical joint, vertical fire barrier 11-2 is set; Form closed fire compartmentation structure;

3), in the topping of crab-bolt 20 outer ends or the surface fire proofing material is arranged, crab-bolt 20 satisfies the fire endurance requirement; As on the crab-bolt surface or topping surface local brushing fire prevention glue, or fire proofing material is joined in the topping of plastering of certain limit on the crab-bolt.
4), described supporting 1-1-5 satisfies the fire endurance requirement; describedly satisfy the fire endurance requirement (during as the bar planting mounting support at major structure of construction 1 built-in fitting (such as embedded bar) that arrange, that be connected with longitudinal reinforcement 6-1 and longitudinal reinforcement 6-1*; organic chemistry glue does not satisfy the fire endurance requirement and just not allows to use; also have at supporting periphery perfusion topping; just can satisfy the fire endurance requirement again so that the anticorrosion requirement had both been satisfied in supporting.Kill two birds with one stone.If do not establish supporting, then there is not this fire protection construction requirement).
In the window frame of the heat insulation break bridge structure outside insulation bar is installed, the topping on insulation bar surface can be the cement polymer elastic mortar+alkaline-resisting screen cloth that thickens, or the fireproof paint of brushing on the topping, brushing fire prevention glue, satisfies the fire endurance requirement.
About some explanation of the present invention:
1, the condition of installing about the formula that reclines:
Abutment face should satisfy certain width, needs to install the additional part that reclines as not satisfying, as on the beam limit vertical concrete being installed.
2, topping 8 layer of concrete for the cement mortar of modification or modification of the present invention comprise following meaning:
1), add Admixture, flyash, stone flour, silicon ash, waterproof agent, water-loss reducer, resistance and split the cement mortar of fiber and other material modification or the concrete of modification, fiber is split in resistance polypropylene chopped strand, alkali-proof glass chopped strand, basalt fibre and hemp cut etc.
2), also comprise cement polymer mortar or the cement polymer concrete that adds water-loss reducer, macromolecule adhesive formation; And the cement silicon ash polymer mortar or the cement silicon ash polymer concrete that also add the formation of silicon ash.Its effect is: 1., lack than conventional cement mortar or concrete intensity height, crack, the protection reinforcing bar is prevented the better effects if of corroding.It is more favourable particularly to adopt the acrylic ester elastic emulsion preparation of vitrification point lower (10 degree～-20 degree) to contain cement silicon ash polymer elasticity mortar or the cement silicon ash polymer elasticity concrete of silicon ash.2., steel nail is easy to and hammer into securely in the cement polymer elastic mortar, and will connect steel disc with steel nail when making things convenient for door and window to install and the cement polymer elastic mortar fixedly secures; And ordinary mortar is easy to cracking, and the nail steel nail is insecure.
3), also comprise the magnesia cement mortar, can be applicable to the building not high to life requirement.
3, about just prefabricated panel and major structure of construction side fixing with crab-bolt: recommend to adopt the plastics crab-bolt, particularly adopt nailing plastic crab-bolt, the accompanying drawing multilist shows nailing plastic crab-bolt, and plastic outer sleeve should adopt the high-strength polyethylene plastic material.Nailing can be injected and be not less than 50mm in the concrete, and penetrable 6～10mm steel plate is connected (can weld steel sheet on the steel work limit) with steel work, and also available bolt is connected with steel work, but trouble.Nailing plastic crab-bolt does not increase heat transfer, and installation rate is fast, price is low, bonding strength can meet the demands, reduce cost, do not increase heat transfer, good endurance.Nailing plastic crab-bolt as the production of existing Chinese Sichuan Nanshan Shooting Nail Fastening Device Co., Ltd.
4, about the reinforcing bar setting:
1), the indoor and outdoor reinforcing bar is generally and is symmetrical arranged, and can a side be bi-steel arranged side by side also, in addition side is single steel bar, stirrup is triangular in shape to socket; The vertical reinforcing bar reply that slip assembling body of wall is installed claims to arrange (Figure 31 and Figure 41 they (2)).The steel plate of installing on the bi-steel arranged side by side can be installed perpendicular to body of wall by Figure 31, or is installed between the bi-steel.Seam crossing is positioned at post or the shear wall place of major structure of construction, and when outdoor vertical reinforcing bar need be set, outdoor longitudinal reinforcement socketed by stirrup and major structure of construction, needs on post or shear wall embedded bar or ironware to be connected with stirrup;
2), the hole horizontal reinforcement is set and prevents plaster topping cracking of door and window hole corner.Horizontal reinforcement generally can be Ф 4 galvanizing steels, conveniently is connected with the both sides reinforcing bar.When being necessary to arrange the bigger horizontal reinforcement of diameter, horizontal reinforcement and both sides, hole reinforcing bar by be connected steel plate and be welded to connect.Horizontal reinforcement can only be positioned at about the door and window hole, also can be positioned at other position, and when for example Figure 13 had two windows arranged side by side, the horizontal reinforcement between two windows can connect and socket.When window is arc, on-the-spot arc sandwich layer and the arch steel installed.
5, anti-shearing about stirrup setting and assembling body of wall:
For will socketing between the indoor and outdoor reinforcing bar, and for making reinforcing bar in topping, be positioned at accurately position, stirrup need be set; The indoor and outdoor reinforcing bar can increase the safety that prefabricated panel is connected with major structure of construction by socketing with stirrup.Stirrup also has makes the assembling body of wall satisfy the effect of anti-shearing bearing capacity.
The sandwich layer of prefabricated panel should be selected good springiness, good endurance, good heat insulation for use, be easy to bonding heat insulating material.When the EPS plate is sandwich layer, EPS plate tensile strength values is between 0.15～0.24Mpa, with reference to concrete structure sloping section strength calculation formula, it is (for reference that EPS plate tensile strength design load is taken as 0.1Mpa, treat that also the expert confirms in the industry), in most cases, body of wall relies on EPS plate self tensile strength can satisfy anti-shearing requirement, and stirrup only is structure setting.Setting gets final product as the stirrup structure with being equivalent to the stainless Ф 2～Ф 3 soft attitude stainless steel steel wires of Unite States Standard 304#.Though be stirrup with the stainless steel steel wire, little because of diameter, weight is few (Ф 2 stainless steel steel wire weight 25g/m), the intensity height, conduct heat less, soft, that bending is installed is convenient, cost low (price during equal length be about Φ 6 reinforcing bars 60%), and good endurance.
Wall between windows is narrower anti-shearing when not meeting the demands, and needs by Structural Design Requirement anti-shearing stirrup is set, as Figure 13, Figure 30.Consider bending resistance, anti-shearing and normal operating condition requirement, may also need the wall between windows thickening could be satisfied the requirement of structural limits state.Ф 2, Ф 2.5, Ф 3 stainless steel tensile strength of wire values are respectively 1.5KN, 2.4KN, 3.4KN.When sandwich layer is alkaline foam cement, though stirrup can be plain bars, increase diameter, difficult bending, construction inconvenience, increase cost, increase are conducted heat.
6, about the installation of vertical reinforcing bar 6-1 and sliding component 2:
Vertical reinforcing bar 6-1 and the sliding component 2 of assembling body of wall of the present invention arrange at a certain distance, when for example stipulating that vertical reinforcing bar 6-1 and sliding component 2 spacings are not more than 2m, the prefabricated panel of failing to grow up in 2m can directly be installed, connect at seam crossing, or by the hole prefabricated panel 15 is assembled into big plate and installs again, but latter's trouble.
7, according to " alkali-resistant glass fibre screen cloth " JCL841-2007 standard, alkaline-resisting strength retention ratio by alkaline-resisting screen cloth is 75%, alkaline-resisting screen cloth tensile strength design load is about 60% of alkaline-resisting intensity retention, convert the alternative steel area of alkaline-resisting screen cloth, the alternative steel of netted tensile materials are used, and see Table 5.
The alkaline-resisting screen cloth tensile strength of table 5 design load, and the alternative steel area of conversion
Figure BSA00000820441700331
Basalt silk and basalt cloth have been arranged at present, also had the basalt reinforcing bar.The basalt fibre net of basalt silk braiding will appear using undoubtedly.The basalt silk has excellent ageing-resistant, high temperature resistant, anti acid alkali performance energy, excellent mechanical property, will be occurred by the basalt fibre screen cloth of basalt silk braiding.Along with development of science and technology, may also have other net that is suitable for doing netted tensile materials, be applied to combined wall of the present invention.
8, about supporting: supporting essence is that body of wall and major structure of construction 1 are at outdoor main tie point.
The steel truss that the steel truss supporting is made up of steel pole; be that pre-buried installation or bar planting are installed or pre-embedded steel slab is installed all very convenient; if around the steel truss supporting, pour into cement polymer mortar; cement polymer mortar reaches specific thickness; can protect the steel pole of steel truss to avoid corrosion and satisfy the fire endurance requirement; and increase rigidity, avoid steel truss supporting forfeiture stable.At the external corner place of assembling building wall, but mounting support is hung outside the external corner sections vertical reinforcing bar, or the external corner place oblique concrete of 45 degree is set cornices, external corner sections outside vertically reinforcing bar cornice with oblique concrete and be connected.
9, about fire prevention:
General prefabricated panel protective layer thickness 25mm (topping that does not comprise reinforcement location) approximately can satisfy fire endurance requirement in 1 hour, can adjust protective layer thickness by fire endurance as required.
The fire barrier of satisfying the fire endurance requirement can be and reaches certain thickness rock wool, foam cement, thermal insulation mortar, glue powder polyphenyl particle, difficult combustion phenolic resins etc. and do not fire or difficult combustion heat insulating material; If with cement mortar or concrete, or increase heat transfer for the concrete of the cement mortar of modification or modification.Wherein brushing fire prevention glue or fireproof paint are recommended to adopt in the door and window hole fire barrier, or difficult combustion phenolic resins, the labour cost but plaster in the hole of conserve expensive are installed.Employing thermal insulation mortar, glue powder polyphenyl particle are recommended in the fire barrier between interlayer, family, are convenient to adjust place, slit error is installed, and install simply, and price is low.In the combined wall insulation layer fire barrier is set, forms the little subregion structure of a kind of closed fire prevention, significantly reduce fire damage, even rough sledding such as war, blast take place, fire can be controlled in the little subregion of fire prevention.
10, about prefabricated panel, when prefabricated batten is light-duty composite insulation boards, the connectivity problem between the sandwich layer:
When the assembling body of wall is installed, need between the prefabricated panel sandwich layer, and the slit between the prefabricated panel, prefabricated batten sandwich layer seals bondingly mutually, and adhering and sealing is fixing that wallboard seam crack easily takes place for seam crossing, and the assembling body of wall can not form a common primary structure member.
1), slit place is bonding with polyurethane foam glue foaming sealing, the tensile strength of polyurethane foam glue foaming should be not less than EPS plate tensile strength values.Polyurethane foam colloid amount difference is big at present, the tensile strength height that has, and pliability is good, and what have is crisp, does not satisfy tensile strength values.
2), also available cement polymer elasticity mortar is bonding in the non-heating region, also available elastic heat preserving mortar is bonding for heating area, during installation with between the prefabricated thermal insulation wallboard, or the bonding installation of jam-packed between prefabricated thermal insulation wallboard and the prefabricated thermal insulation batten.The elastic heat preserving mortar is that the fine sand in the cement polymer elastic mortar is substituted with glass bead or vitreous pearlite, and is bad because of insulating dry powder mortar elasticity, to adapt to sex change bad, easy to crack, should not use.
11, about the horizontal loading perpendicular to metope:
Prefabricated panel is light-duty composite thermo-insulating wall board; the various materials of light-duty composite thermo-insulating wall board are connected as a single entity; form the primary structure member of an integral body; when protective layer thickness 25mm; the assembling body of wall is from heavy and light, and to the combination of Beijing area wind load combination and horizontal earthquake action and wind load, the two gets its large one; making usefulness is started to control in the wind load combination, and the wind load combined value is horizontal earthquake action and wind load combination 2～2.5 times.To most areas, also be that making usefulness is started to control in the wind load combination.Namely when earthquake intensity was higher than normal chance earthquake one-level, the assembling body of wall self was safe.
When light-duty composite thermo-insulating wall board forms the primary structure member of an integral body, bending resistance can be increased by adjusting core layer thickness and adjusting netted tensile materials specification, only assembling body of wall bending resistance designing requirement can be satisfied mostly with netted tensile materials.1), weak location arranges reinforcing bar at the hole, satisfies the bending resistance designing requirement of cross section, the edge of a wing, hole the purpose that the prefabricated panel seam crossing arranges longitudinal reinforcement is:; 2), when the local interruption of cornicing arranges, the reliability that reinforcing bar increase to like that the assembling body of wall is connected with major structure of construction is set, but wallboard is subjected to not need to consider in the curved design bending resistance effect (because of far) of longitudinal reinforcement apart; 3), the body of wall hanger is installed reinforcing bar need be set; 4), slip assembling body of wall need arrange reinforcing bar.
The situation that horizontal loading is very big is rare, the wind reference pressure 1.8KN/m of China's maximum 2(Xisha), 1.85KN/m 2(Yilan of the island of Taiwan), the prefabricated panel of span 3m freely-supported calculates by building height 30m, considers height coefficient, gustness factor, wind load bodily form coefficient, and the correction factor that has the adverse effect of door and window hole, the horizontal wind load combined value of metope just reaches 8～10.0KN/m when 30m is high 2Huge value, calculated bending moment is very big, may can not satisfy the requirement of bending resistance arrangement of reinforcement with netted tensile materials, this just need arrange longitudinal reinforcement 6-1*.
12, comprise in the time of need satisfying the ultimate limit state designing requirement:
1), the ultimate limit state design is with reference to the regulation of " Code for design of concrete structures " GB50010;
2), serviceability limit state design:
Evidence: sandwich layer EPS plate thickness 140mm, both sides each 30mm of cement mortar protective course thickness, prefabricated panel thickness 200mm, span is the simply supported slab of 3.0m, when composite thermo-insulating wall board forms the primary structure member of an integral body, at vertical load 2.5KN/m 2Under the effect, amount of deflection only is 3mm.When large span and horizontal loading are big, and the light-duty plate of new material should detect deformation values by test, with amount of deflection control in allowed band.
13, determine that assembling body of wall core layer thickness need consider following factor:
1), whether needs to satisfy the ultimate limit state designing requirement.
Increase core layer thickness and help to satisfy bending resistance and anti-shearing, and reduce flexural deformation.
2), satisfy the energy-saving heat preserving requirement.
The minimum thickness requirement of sandwich layer when 3), satisfying the mounting slip member.
4), the permanent construction thickness of wall body will satisfy the comfort requirement.
When assembling body of wall core layer thickness was too thin, Indoor sill was too narrow, and comfort is poor, and the core layer thickness of recommendation permanent construction should not be less than 150mm, and body of wall gross thickness 200mm is to satisfy the requirement of residence comfort.
14, when prefabricated panel is light-duty composite thermo-insulating wall board; how to guarantee the reliability that is connected between assembling body of wall topping and the sandwich layer; make the assembling body of wall can form the primary structure member of an integral body; prolong the durable years of assembling body of wall; make it to be not less than 50 years; prevent and reduce the common quality defect of assembling body of wall topping cracking, except guaranteeing that steel satisfy the anticorrosion requirement, recommend to take following technical measures:
1), establish than the dovetail type groove at tabular sandwich layer such as EPS plate, increases being connected between topping and the sandwich layer.
When processing light-duty composite thermo-insulating wall board with special equipment, the dovetail type groove planted agent in EPS plate bottom scrapes earlier and smears cement polymer mortar, particularly the cement polymer elastic mortar.Cement polymer elastic mortar good springiness, to adapt to the distortion cracking resistance good, or also add the silicon ash in the polyacrylate elastic emulsion, and the small-size effect of silicon ash can increase bonding reliability.
2), take the brushing interfacial agents to build the job practices of topping at high molecular tabular sandwich layer.
Interfacial agents is prepared with synthetic resin emulsion liquid such as polyacrylate dispersion raw material, and the adhesive raw materials in the interfacial agents and the ratio of water should be not less than certain numerical value.Interfacial agents essence is cementing agent, the bonding requirement difference to interfacial agents (or being referred to as bonding adhesive) between the different materials, and for example mutual when bonding between the inorganic material, possible plain-water slurry just satisfies the bonding requirements as interfacial agents.
When qualified, can effectively guarantee that interfacial agents is bonded together topping and sandwich layer at the interfacial agents quality of preparation and brushing quality.Experimental results show that; the EPS plate is cut a hole to such an extent that depression, cement mortar are comminution destruction when knocking the destruction topping with hammer; but bonding interface still bonds; composite plate after this destruction is immersed 24h, freezing 12h in the water; take out again and dissolve, steep again in the entry; multigelation experiment 50 times, bonding interface does not destroy, and illustrates that freeze-thawing resistant and water resistance satisfy instructions for use.
3), to topping watering health, be to prevent that topping is bad because of health, the necessary condition of efflorescence cracking takes place.
4), quality of materials should be qualified.For example qualified core material should be selected for use and satisfy tensile strength values, good springiness, is easy to material bonding, good endurance, and sandwich layer can be to topping cracking formation restrictive function with reliable connection of topping.
5), can partitioning slot need be set in conjunction with decorating; plug elastic packing waterproofing materials in the partitioning slot, the netted tensile materials in the floated coat can be communicated with, and the topping that netted tensile materials is outer and outside finish disconnect; partitioning slot can be used as ornamental strip, can reduce the crack that takes place because of variations in temperature.
The thin heat-preserving wall of plastering that Germany carried out in the seventies, outer mask ftractures, and progressively keeps in repair.They think EPS plate that the 50mm of original installation is thick and meet the demands with the bonding cement polymer mortar adhesive linkage quality of basic unit body of wall.So peeled the thin topping of plastering of cracking off, paste the thick EPS plate of 150～200mm in the above again, think to re-use more than 30 years.This explanation, the cement polymer interfacial agents, the cement polymer mortar durability that be not positioned at the ultraviolet ray irradiation, not degraded by wind and rain can be not less than 60 years.
When 15, assembling body of wall of the present invention was energy-saving wall, prefabricated panel should be composite thermo-insulating wall board; During non-energy-saving wall, prefabricated panel can be concrete slab, lightweight concrete slab etc.
16, the connection that is connected with reinforcing bar of netted tensile materials of the present invention realizes by the following method:
When 1), the prefabricated panel seam crossing is installed prefabricated batten; vertical reinforcing bar 6-1 is arranged in the prefabricated batten; when topping is smeared in the prefabricated batten outside (smearing the cement polymer elastic mortar is advisable); the netted tensile materials of installing overlaps bonding the connection with the side prefabricated panel, thereby prefabricated batten is connected with prefabricated panel.Be netted tensile materials and being connected by the bonding connection of cementitious materials of reinforcing bar.
2), in that the prefabricated panel seam crossing is on-the-spot when reinforcing bar is installed, netted tensile materials is connected with reinforcing bar binding; Add the plaster bonding connection of cementitious materials of topping of reinforcing bar.
17, about selecting wherein a kind in the embodiment two, eight, or 1), 2), 3) plant collocation and share problem:
For prefabricated panel is installed, install for convenient construction, must select to fix with crab-bolt and major structure of construction, because fixed prefabricated panel with crab-bolt, prefabricated panel is just motionless.But for prefabricated batten, because it also has inside and outside vertical reinforcing bar and major structure of construction to fix, therefore not necessarily need to fix with crab-bolt.
18, install about door and window:
The prefabricated batten 15-1 that is positioned at the hole should the pre-buried ironware that is connected with the window level reinforcing bar or reinforcing bar 6-3 (Figure 41).
When door and window is installed, with the installation steel disc on the door and window staggered with Figure 31, Figure 41 they (2) on the steel disc 6-3 that is connected that installs on the reinforcing bar of window limit fix.Connecting steel disc 6-3 can install by Figure 31, also can install by it (1) of figure Figure 41, but Figure 31 and Figure 41 they (2) guarantees thickness of protection tier easily.
The slit between thin covering window frame of insulation and the body of wall should be installed in outside, heat-insulating bridge-cut-off hole.
19, the common assembling body of wall of embodiment of the present invention one～six also can be applicable to shear wall structure; though increased the cost of prefabricated panel; but reduce engineering quantity, the expensive artificial expenditure of minimizing that the outer protection layer is plastered, and can reduce the coefficient of thermal conductivity of heat insulating material.When being applied to shear wall structure, indoor reinforcing bar needn't be set.
When 20, the assembling body of wall of embodiment of the present invention one～six, window are horizontal moulding, between window lower end and the assembling body of wall except with the elaxtic seal sealing, also the slip stop can be set, the slip stop is connected the window lower end with the assembling body of wall of horizontal moulding, then this window can be along with the upper floor slippage, be applied to the house balcony window, and in the body of wall of horizontal moulding.
