Abstract
The invention relates to a prefabricated fine-pore concrete insulation board, which is made mainly by distributing fine pores on the concrete inside and the surface of a prefabricated concrete board. The fine pores can prevent heat conduction, absorb sound waves and improve the efficiency of the prefabricated concrete board serving as the insulation board. Plant insulation materials are filled in the board, so the heat conductivity is reduced by nearly 10 folds compared with that of common bricks. Anti-cracking and anti-seismic reinforced steel bars are arranged in the board transversely, so the loading capacity far exceeds that of cast-in-situ concrete boards. The construction cost of an insulation wall made of the prefabricated fine-pore concrete insulation boards is lower than that of the insulation wall made of the bricks, and the construction cost of an floor made of the prefabricated fine-pore concrete insulation boards is 10 folds lower than that of a cast-in-situ concrete floor.

Summary of the invention
In order to restrain reproduction heat-preserving wall cost height is arranged, intensity is low, and application life is short, and low income personnel purchase and cannot afford, and do not have to popularize use; Have prefabricated concrete hollow slab easily to crack not heat insulation defect in order to restrain reproduction, cast-in-situ floor cost height is heat insulation defect not; It is low to the invention provides a kind of cost, the intensity height, and long service life, low income personnel purchase and can afford, and can popularize use, the prefabricated heat preservation wall body plate that does not crack, insulation floor.
The object of the present invention is achieved like this: the present invention adopts a kind of fine-pore concrete or the concrete prefabricated one-tenth hollowcore slab of building with specific process; And directly pack in inside plant heat insulating material or waste and old heat insulating material are made warming plate; The plant heat insulating material refers to husk, cotton seed hulls, hay, stalk, broken etc., and waste and old heat insulating material refers to waste and old chemical foam heat insulating material and waste and old mineral goods heat insulating material such as waste and old expanded perlite, mineral wool, rock wool, glass wool etc.; The reinforcing bar that laterally vertically is provided with at plate is made insulation antidetonation plate.Build earthquake-resistant energy-saving house with this precast concrete warming plate, cheap quality is good.It all is to adorn heat insulating material in body of wall that the present invention slightly seems the same with existing patent, existing prefabricated concrete hollow floor is by the ordinary concrete main body and the longitudinal prestressing reinforcing bar is set constitutes, and the present invention has adopted several new methods, 1, be in the large scale prefabricated plate of 240 millimeters thick, to adorn heat insulating material, 2, what heat insulating material was used is plant heat insulating material or waste and old heat insulating material, 3, the plant heat insulating material is direct use, rather than use after making warming plate with cementing agent, 4, adopted fine-pore concrete, 5, at the horizontally set of plate reinforcing bar, two plate transverse reinforcements can connect becomes a whole reinforcing bar.Concrete grammar is as follows:
Prefabricated fine-pore concrete insulation board, ash wall body plate, warming plate: this plate is dress plant heat insulating material or a waste and old adiabator goods formation warming plate in the main body with fine-pore concrete, improves shock resistance at plate horizontally set reinforcing bar.The approach that the one side of the existing hot slave plate of prefabricated concrete hollow floor is transmitted to another side has two, the one, spread out of to the another side concrete again from a surface concrete to hollow air, the 2nd, the connection concrete in the middle of from a surface concrete to two holes spreads out of to the another side concrete again.One of reason that existing prefabricated concrete hollow floor thermal conductivity is high, be the thermal conductivity 1.40X 10^ (6)/℃ than loam brick 0.76X 10^ (6)/℃ high nearly 2 times of ordinary concrete, in order to reduce the thermal conductivity of ordinary concrete, ordinary concrete is made fine-pore concrete, the fine pore can stop conduction of heat to absorb sound wave, and its thermal conductivity ratio loam brick reduces more than 2 times.The casting method of fine-pore concrete: generally building ordinary concrete is to be cast in the coagulation forming that vibrates in the model after rubble, sand, cement, water are stirred into the sposh shape by a certain percentage; Also having a kind of roller compacted concrete is to complete earlier after rubble, sand, cement are stirred by a certain percentage to roll, and rewaters to allow the moulding that thes cement solidifies; The present invention makes it little wet adding a spot of water after rubble, sand, the cement mixing, with stirring the cement sand is attached to and forms graininess on the rubble, be cast in the model then, with certain amplitude vibrate or certain strength roll coagulation forming, Jiao Zhu concrete has been covered with the fine pore like this; The fine pore can stop conduction of heat to absorb sound wave, so can make warming plate.The quality of prefabricated fine-pore concrete insulation board is guaranteed: the fine pore in the concrete has reduced the intensity of precast plate, but experimental results show that this plate intensity and thickness much larger than available coagulation soil hollow brick, this plate is as long as the heat-insulation wall plate intensity that work does not laterally stress is enough; Moreover building construction will be used cement sand plaster, when the plate cement mortar of wiping one's face during with cement sand plaster in fine pore is infiltrated in the plate 3 to 8 millimeters from the slit, the cement mortar of wiping one's face and precast plate become one fully, the cement mortar of wiping one's face adds the interior cement of infiltration plate and has formed the above intensity cement layer of nearly 20 millimeters thick C30, the two sides of the plate above intensity cement layer of nearly 40 millimeters thick C30 of having added up, high strength surface water mud layer has been strengthened the intensity of fine-pore concrete plate.The prefabricated fine-pore concrete insulation board convergent force is little, two plates also pour into interior 3 to 8 millimeters of cement mortar slave plate side concrete fine pore infiltration plate in the seam together during installation, the two synthetic justifyings that harden, seam crossing intensity can not crack greater than the intensity of hollow position.Compact zone: see at the position up and down of hollow hole concrete more closely knit than its elsewhere from the horizontal section that cuts plate, stressed bigger formation was built in relative its elsewhere when this built owing to this position concrete is thin, strengthened the intensity at the thin place of top concrete like this, whole fine-pore concrete precast hollow slab intensity has been improved.High former of existing prefabricated concrete hollow floor thermal conductivity two is cross-ventilations of hollow interior therefore, in the plate behind the dress heat insulating material cross-ventilation conduct heat and become the heat conduction of heat insulating material, the plate thermal conductivity can reduce by 6 times behind the dress heat insulating material.So adopt plant heat insulating material or waste and old heat insulating material goods not to have the secondary operations expense low; Plant heat insulating material such as husk, cotton seed hulls, hay, stalk, broken etc., these materials have all burnt now, the burning straw between the farmland that has is contaminated air also, so cheap, waste and old heat insulating material goods are also cheap; Just few the heat insulating material very simple expense of packing in the prefabricated concrete hollow slab; These schemes make the cost of its plate also cheaper than brick.Plant heat insulating material quality is guaranteed: we know that a good banda used 50 years at most, and a husk pillow can use last 100 years, can guarantee that the plant heat insulating material is never rotten if with the PV plastic sheeting plant heat insulating material is carried out protection against the tide.By above change to existing two heat conduction path of prefabricated concrete hollow floor, heat conduction path one of the present invention is to spread out of to the little concrete of another side to heat insulating material from the little concrete of one side again, the 2nd, and the connection fine-pore concrete middle from a fine-pore concrete to two holes spreads out of to the another side fine-pore concrete again; Fine-pore concrete and heat insulating material be good heat insulating all, and the present invention becomes insulating board.It is heat insulation that this plate need not be adorned heat insulating material during as the partition wall in house, parapet.In order to improve earthquake-resistant building, plate laterally vertically increase anti-seismic steel bar, its reinforcing bar is lingered on joint outside plate, during installation adjacent reinforcing bar connector being connect becomes a long reinforcing bar and is connected with collar tie beam, body of wall becomes as a whole and has the reinforcing bar shock resistance strong; When using, anti-seismic steel bar also to give certain prestressing force.
Prefabricated anticracking ordinary concrete warming plate, floor, cast-in-place plate: this plate with ordinary concrete be in dress heat insulating material and the plate longitudinal prestressing reinforcing bar is set in the main body, transverse reinforcement constitutes together.Can only make body of wall thereby fine pore precast concrete warming plate intensity is low, make floor and will use ordinary concrete; Because of bearing gravity, floor equally to vertically dispose prestressed reinforcement with existing precast hollow slab.For the adhesion that solves horizontal piece concrete of pre existing making sheet and precast plate concrete joint surface adhesion less than inside concrete, the problem that the bonding surface that adhesion is little in constantly expanding with heat and contract with cold cracks, the present invention has disposed horizontal anticracking reinforcing bar in plate, reinforcing bar is longer than the floor width and lingers on joint outside plate; When being installed in the method for welding the transverse reinforcement connector of adjacent two boards to be coupled together after architectural, this plate makes long reinforcing bar of transverse reinforcement formation, transverse reinforcement forms steel mesh reinforcement with longitudinal reinforcement, form an integrated prestress plate, with reinforcing bar the reinforcing bar connector around the whole floor being linked up the after-pouring concrete again becomes one plate and body of wall, form integral prefabricated prestressed in-situ depositing plate, promptly become the same floor of present cast-in-place plate; And the ability of bearing gravity is much larger than cast-in-place plate; This plate is as floor, the roof panel in house.This plate is made floor can not adorn the heat insulating material use.
Prefabricated composite concrete board thermal insulation board, composite plate: this plate top is the compound formation of ordinary concrete for the fine-pore concrete bottom, and other are with above-mentioned two plates; This plate can be with the equally stressed effect of heat insulation of having strengthened again of prefabricated anticracking ordinary concrete warming plate.What we knew that plate upper portion pressurized face bears is pressure, and very little to this power, what bore the bottom is pulling force, is mainly stressed, is determining this plate can bear gravity; Because the bottom is the same with common precast hollow slab, so this plate equally bears gravity with existing precast hollow slab; The top of composite plate is fine-pore concrete, and the fine pore can stop conduction of heat to absorb sound wave, so this plate has certain heat-insulating sound-insulating ability, can not adorn heat insulating material and do the warming plate use.The bottom of this plate is an ordinary concrete, and two harden the adhesion of concrete joint surface of the joint concrete of joint close and plate less than the adhesion of concrete itself, and long back of time is crackle easily, thus this plate laterally the anticracking reinforcing bar to be set; The transverse reinforcement connector of adjacent two plates is linked up long reinforcing bar of formation, form steel mesh reinforcement with longitudinal reinforcement, can be with now burning the same seismic crack of plate; It bears the gravity ability much larger than cast-in-place plate.This plate is as floor, ash wall body plate.
The precast concrete board thermal insulation board assemble plate, body of wall assembles plate; At the position that door and window is arranged, build by laying bricks or stones in the big plate in the rural area that does not have crane very heavy just being difficult for, need be divided into the short slab that can build by laying bricks or stones to above-mentioned three kinds of plates and promptly build and build plate and build by laying bricks or stones.Building plate by laying bricks or stones should not influence the load-bearing of body of wall, so upper and lower plates hollow hole place wants with one heart, the seam of the upper and lower plates of building by laying bricks or stones should be on a line; The present invention adopts at the middle institute of the longitudinal center's two hollow holes concrete width that stays of plate the same with both sides joint concrete width, the seam facing to lower plate of upper plate center line, so just makes the collinear and seam fissure of displacement of hollow position up and down when building by laying bricks or stones; Make fissure of displacement plate with the half block plate.General dwelling house chamber height is below 2.8 meters, and it is high below 2.4 meters to remove the actual wall of collar tie beam; For the ease of building by laying bricks or stones body of wall is divided into several joints, can be convenient to like this build by laying bricks or stones; If be divided into 2 joint fine-pore concrete prefabricated thermal insulation plates then have only 1.2 meters long, if 240 millimeters of thicknesss of slab, wide 1.4 meters, every block of plate weighs 400 kilograms, and the several people just can lift and build by laying bricks or stones; The minor crane of frame on the room built by laying bricks or stones and built that to build plate very simple.
Beneficial effect: intensity height, this plate adopt concrete main body can adjust the intensity of cement proportion control panel arbitrarily.Antidetonation, concrete can increase reinforcing bar arbitrarily in plate diameter or quantity increase shock strength.Insulation, the heat-insulation and heat-preservation material fine-pore concrete prefabricated thermal insulation plate of packing into by 240 millimeters thick, plant heat insulating material and waste and old heat insulating material thermal conductivity are all very low, as hay thermal conductivity coefficient be 0.047X 10^ (6)/℃, if fine-pore concrete thermal conductivity coefficient be 0.252X10^ (6)/℃, the thermal conductivity coefficient that calculates this plate be 0.145X 10^ (6)/℃, than concrete brick thermal conductivity coefficient is 1.10X 10^ (6)/℃ reduce nearly 8 times, adopt huge hole after thermal conductivity can reduce nearly 10 times.Quality is good, and with husk, cotton seed hulls, hay, stalk, broken, the exterior wall in house is directly drenched with rain and moist the heat-insulation and heat-preservation material, the moistureproof PV plastic sheeting of alternating floor between heat-insulation and heat-preservation material and concrete core unit with plant; A good banda used 50 years at most, and a husk pillow can use last 100 years, and moistureproof PV plastic sheeting can guarantee that the plant heat insulating material is never rotten; Equally never rotten with waste and old Xylonite foam, waste and old mineral expanded perlite mineral wool glass wool heat insulating material; Concrete also be thousand not bad.Cheapness, this plate can be economized nearly half body of wall materials, and the waste and old heat insulating material of plant heat insulating material is cheap; Do not need formwork, can save nearly ten times as floor without pump delivering concrete expense; Use this plate can reduce cost of a building.So the present invention has ten big beneficial effects:
1, intensity height is because use is the intensity that concrete can be adjusted the cement proportion control panel arbitrarily;
2, quality height and since use be in concrete and the PV plastics bag plant heat insulating material can guarantee thousand not bad; The globality of body of wall, floor is the same with cast-in-place plate, so can not crack;
3, antidetonation, the diameter or the quantity that can increase reinforcing bar in the configuration plate arbitrarily increase shock strength;
4, body of wall is light, so owing to be that the heat insulating material body of wall is light in the plate;
5, energy-conservation, owing to be the fine pore plate, heat insulating material is equipped with in inside, reduces nearly 10 times than concrete brick thermal conductivity, so energy-conservation; So be that hollow half body of wall materials of can economizing have into also been saved the energy in the plate; If national house all adopts this warming plate, the electric coal of annual heating air conditioning can be saved and exceed 100 billion.
6, easily build by laying bricks or stones, adopt to assemble plate and build door and window by laying bricks or stones and do not need lintel or formwork, also can build by laying bricks or stones without crane;
7, increase the house usable floor area, can satisfy requirement of strength to the house inner partition wall with 180 millimeters plates or 120 millimeters, so can increase the house usable floor area;
8, save time, because this plate area is greatly that integral body is built by laying bricks or stones, 12 square metres wall just can be built by laying bricks or stones in one hour, than building fast tens times of fritter brick wall by laying bricks or stones, was used as floor and need wait for solidifying than cast-in-place plate and lack last ten day of time spent;
9, cheapness is so owing to be hollowly can economize into half body of wall materials in the plate, the waste and old heat insulating material of plant heat insulating material is cheap; Do not need formwork, can save nearly ten times as floor without pump delivering concrete expense; So use this plate can reduce cost of a building, low income personnel purchase and can afford.

With reference to figure 1 prefabricated fine-pore concrete insulation board organigram, the main body of this plate is fine-pore concrete [1], fine-pore concrete inside has been covered with fine pore [2], be provided with anti-seismic steel bar [3] in the plate, plant heat insulating material or waste and old Xylonite cellular insulant, waste and old mineral goods heat insulating material [4] are equipped with in inner strip hole; Laterally anti-seismic steel bar [3] length leaves connector greater than the width of plate outside plate, the horizontal edge reinforcing bar [3] of this plate is located recessed one and is used for reinforcing bar connector connection usefulness, adjacent two slab muscle [3] connectors is coupled together go into a long reinforcing bar [3] in the continuous shock resistance that improves of wall frame; General house can be provided with anti-seismic steel bar [3] as one-storey house, and the wall that need be incubated can not adorned heat insulating material [4].There is a compact zone in the place, top, hole of this plate.This plate is mainly used in body of wall.
With reference to figure 2 prefabricated anticracking ordinary concrete warming plate organigrams, the main body of this plate is ordinary concrete [5], have in the plate horizontal anticracking reinforcing bar [7] and with hole longitudinal prestressing reinforcing bar [6] in the same way, adjacent two plate transverse reinforcement [7] connectors are coupled together form steel mesh reinforcement of a long reinforcing bar and longitudinal prestressing reinforcing bar [6] formation, steel mesh reinforcement reinforcing bar [6] [7] connector links to each other with the framework reinforcing bar, prefabricated anti-crack concrete warming plate is not split with cast-in-situ reinforced concrete slab is the same, and its ability of bearing gravity is much larger than cast-in-place plate.This plate mainly is used as floor, the roof panel in house.
With reference to figure 3 prefabricated composite concrete warming plate organigrams, the top of plate is fine-pore concrete [1], and the bottom is ordinary concrete [5], is vertically arranged with prestressed reinforcement [6], is horizontally arranged with anticracking reinforcing bar [7]; Because the bottom is the same with prefabricated anticracking ordinary concrete warming plate, so equally bear gravity; This plate is as floor, the ash wall body plate in house.The top of this plate is fine-pore concrete, and the fine pore can stop conduction of heat to absorb sound wave, so this plate does not add heat insulating material [4] certain heat-insulating sound-insulating ability is not just arranged, and can not add heat insulating material [4] and use as the heat-insulating sound-insulating floor.
With reference to the huge hole of figure 4 prefabricated composite concretes warming plate organigram, this plate is that the circular hollow hole in Fig. 3 plate has been changed into huge hollow hole, the slim concrete height that changes in the middle of two holes of plate behind the huge hollow hole has been increased, increased the passing time of heat, the further like this effect of heat insulation that improves plate; But the ability of bearing transverse gravity has reduced a lot.Because the bottom is an ordinary concrete [5] the intensity height than brick is outwards arranged, top is that fine-pore concrete [4] inwardly has fine effect of heat insulation, so this plate is fine as external wall insulation.Replace anticracking reinforcing bar [7] with auxiliary anticracking reinforcing bar [8] when the floor load-bearing is little, auxiliary anticracking reinforcing bar [8] is a bar dowel, length of embedment will reach first vertically has prestressed reinforcement [6] to locate, and auxiliary like this anticracking reinforcing bar [8] is just with vertically there being prestressed reinforcement [6] to be connected in; The auxiliary anticracking reinforcing bar [8] of adjacent two plates but couple together just anticracking.
Fig. 5 prefabricated fine-pore concrete insulation board assemble plate, this plate is the short slab of top three kinds of plates, is used for masonry panel; The width that promptly assembles district not lend oneself to worry and anxiety [9] in the plate at the middle concrete that stays of longitudinal center's two hollow holes of plate equals the width that the both sides joint concrete promptly assembles edges of boards district [10]; The seam facing to lower plate of upper plate center line, the hollow hole place is collinear about so just making prevents crackle with the seam fissure of displacement when building by laying bricks or stones; Make fissure of displacement plate with the half block plate.Be provided with horizontal anti-seismic steel bar [3], adjacent two slab muscle [3] couple together the raising shock resistance.
The prefabricated antidetonation joint that assembles plate of Fig. 6, ordinary concrete slit bonding surface adhesion is less than the intensity of ordinary concrete own, assembling pre-buried plate joint bar dowel [11] that assembles of plate joint bar dowel, a reservation assembles plate connector slot [12], and the bar dowel of upper plate [11] inserts connector slot [12] the enhancing joint strength of lower plate when building by laying bricks or stones.General body of wall does not need to use this joint, is used for special body of wall.
Combine schematic diagram with body of wall when the prefabricated anticracking ordinary concrete of Fig. 7 warming plate is made floor, become reinforcing bar [6] [7] connector of steel mesh reinforcement to link to each other among the figure in the plate with the collar tie beam reinforcing bar, wait to build concrete after formation with the same floor of present cast-in-place plate.
Fig. 8 prefabricated fine-pore concrete insulation board combines schematic diagram with body of wall, left partial sectional view reinforcing bar connector [3] is welded on the built-in fitting among the figure, right partial sectional view is cast in reinforcing bar connector [3] in the column collar tie beam together, plate and column and collar tie beam are connected together, make body of wall become an integral body, improved the shock resistance of body of wall.
