Punch the ribfrom top to bottom of roof, and the spacing of ribpunching is 1.0 m.(5) Pouring fine stone concreteThe large-area of fine stone concrete is laid out(the mix proportion shall meet the designrequirements), the trowel is used for spreading, andthen short wooden pole is used to slick according toboth sides of rid punching elevation. Next, thewooden float is used for leveling, and then thewooden rod is use to check its evenness. When theconcrete begin to condense and people step on it,having footprints but no caving, the iron float isused to press it for the second time. Attentionshould be paid to prevent the lack of compaction,and the dead pit, blind angle and sand hole aretrowelled. When the trowelled cannot be pressedinto the smear lines, and then level out and compactit.3.2.5 Construction of Tiled Finish Coat(1) Roof paying offAfter roof structural layer, waterproof layer,thermal insulating layer and protective layer, etc.are strictly accepted according to the design and theCode for Acceptance of Construction Quality ofRoof. The roofing counter batten and batten arepaid off on the completed roofing tiled base course.The paying-off must be positioned accurately.(2) Arrangement of counter batten and battenThe counter batten and batten should adoptconiferous species of 25 25 (mm) and 30 25(mm), with about 6.2 m per square meter. Beforeusing, the diesel asphalt mixture is used for theanti-corrosion treatment. The tile is fixed with 5060 (mm) steel nail. The center spacing for counterbatten is 350-500 mm perpendicular to the roofE-ISSN: 1817-3195eaves with uniform arrangement. The counterbatten is fixed on the concrete base surface withcement steel nail according to the position of chalkline. The spacing of nail @ is 450 mm or less, andthe counter batten should be parallel with thecornice. The top is cut into a bevel angle parallelwith the ridge (30 mm away from the ridge). Thebottom is in the convex angle (ridge and eaves)20mm away from the eaves edge, and its endsshould be parallel with other counter battens. Apiece of counter batten is nailed on both sides ofslopping ridge, and cement paste is used on bothsides for enhancement. The uneven place of lowersub-base of counter batten can be slanted andpadded with anticorrosive wood wedge. And Theflux line is pulled for leveling.The center spacing of western-style batten is 285mm, the batten is fixed in the counter batten withL 60mm nail, and the joint between each battenand each counter batten should be nailed. Thebatten should be nailed neatly and firmly, the topedge should be in a straight line, which all shouldbe parallel with the batten on the cornice and roofeaves. Meanwhile, the joints should be staggered onthe counter batten. Two battens are set on the eaves,and its height should be 50-60 (mm) upwards fromthe counter batten. The flux line is pulled forleveling.(3) The dry-hung method (nail-hanging method)is adopted for laying large-scale plain roofing tile.After the counter batten is leveled, the roofingbatten can be laid with the tiles. The first tile is laidfrom the left bottom of eave (skew plate), from leftto right and bottom to top. The tile is fixed on thebatten with steel nail, and the overlap joint of tilesshould be fully used, to ensure the evenness of tilesand waterproof performance. The tiles areoverlapped each other, and the left lower gap andthe upper right gap must be aligned in place, whichare nailed down with steel nails. The upper tilepresses the nail cap of the lower tile, to savewaterproof rubber mat. So, it can prevent theleakage of water, but need not use the rubber stripfor filling the gap. If the number of entire tilecannot reach, the portable cutting machine will beapplied for cutting. The length for tile stretchinginto roof gutter and eave gutter is 50-70 mm, andthe length for tile cap picking out the verge board is50-70 mm.The distance between the tile interior surface andthe lying tile base course is usually kept in 50-70mm (i.e. overhead), so as to have adiabaticventilation effect.204

All rights reserved.ISSN: 1992-8645www.jatit.org(4) The cement paste wet-lying method isadopted for laying ridge tile on the roofing inclinedridge.After the plain roofing tile is laid in order, in theroofing inclined ridge, from top to bottom two“Flat” and “Straight” flux lines should be pulled ns of ridge tile. Starting from the bottomof inclined roofing ridge, the inclined ridge tiles areinstalled to the top of inclined roofing ridge frombottom to top according to the provisions of laplength. Each edge for imbrication width of ridge tileon both slopes should not be less than 40mm.The shield-shaped tile is divided into straightridge shield-shaped tile and inclined shield-shapedtile, respectively used in both sides of straight ridgetile and inclined ridge tile. The top of joint of threeway sloping roof, namely, the joint of two inclinedridges and main ridge, adopts three-way ridge offittings tile.Considering the straightness of ridge tile at thejoint of inclined ridges, it is appropriate that theridge tile needing to be cut uses two-time cuttingmethod.1) Before formal paving, the first incision isrequired. In this incision, a little more remainingpart should be kept.2) After paving, the cutting auxiliary line isstraightened from the roofing upper to the lower.The original remaining part is cut evenly for thesecond time, so the cutting joint of two inclinedridges can be cut in order.In the roofing inclined ridge, cement mortar inthe proportion of 1:2 is coated. In order to avoid theinfluence of lower-temperature frost heave in thewinter on lying tile mortar, it is advisable that theplumpness of mortar ridge of t tile and lying tile iscontrolled at 80%. The gap is reserved betweenbase course and ridge tile, and the ridge tile isinstalled on the cement mortar and fixed withreinforcing steel nail. The mortar is brushed withthe coating, of which the color is same as that of thetile. The above measures are taken to prevent ridgetile falling off because of the low-temperature frostheave.(5) Processing for tile edging and cornicesThe convergence of tile edging is coated, pressedand compacted tightly with cement mortar in theproportion of 1:2, and it is done in the prismaticsame as the shape of tile edge. After seven daysafter roof construction, the special coating ofE-ISSN: 1817-3195cement tile, which has the same color of roof, isused to coat the gray part naked externally for twotimes. The special coatings belong to water-basedpaint. If the paint seems to be thick, fresh water notmore than 10% can be added for dilution. Pleasenote that oil items cannot be used for dilution suchas gasoline, xylene and so on. The storagetemperature of paint is from 4 to 30 .Attention should be paid to protect the neatnessof tile, and the surface of tile should not becontaminated, and be cleaned promptly. In thecornice, cement mortar is used to seal the firstdouble-layer batten, and the reinforcing steel barwith the diameter of 20mm is used to poke a holebetween two counter battens, for easy drainage andventilation.(6) Node processingIn the roof, there are parts in which tiles arecombined with wall or other structures, theprocessing for these parts is the key to roofwaterproof. In the processing, the combiningmethod and materials must be seriously considered,and the construction should strictly comply with thedesign requirements or the corresponding standardatlas.1) The method to pave the sewer tile: pop thecenter line of sewer and then pop two parallelpaving lines about 60 mm apart from the left orright of the center line. The effective width ofsewer tile is about 215 mm, among them, the widthof open trench is 120 mm, and the rest is cementmortar-bottom (the pulp is 50 cm or so). Whenpaving, the center of ditch tile should be lowered asfar as possible, and the pulp given priority to onboth sides of every piece of ditch tile, creating theconvenience for laying the following main tiles.The linkage line at about 60 mm on both sides ofthe center line between the first and the last sewertile is regarded as the cutting line of main tile. Thecement mortar in the proportion of 1:3 is used foractual cutting part (400 mm on both sides), in caseof leakage of water in the rain.2) The flashing width of side tile sticking into theroofing wall should not be less than50 mm.3) The procedure for cutting the main tile:according to the requirements of roof cutting angle,at first, the cutting line need to be marked out onthe tile surface with slate pencil and strip line, theelectric circular saw is used to cut the main tilealong the cutting line, cement mortar in theproportion of 1:3 is used as the main tile incised.205

All rights reserved.ISSN: 1992-86454.www.jatit.orgCONCLUSIONSThe Hengda Oasis project adopts the newtechnology of dry-hung and wet-lying in theconstruction of roof with steep slope in severe coldregion. In comparison of the method of traditionalsloping roof single-layer framework bracing castconcrete, it greatly shortens the construction period,and saves labor cost. Combined with actualconditions in the severe cold region, “L” shapelacing bar is set in each structural layer of the roof,to connect each structural layer of the roof, so thelatter maintenance cost is greatly reduced. Takingthe above aspects into consideration, the HengdaOasis engineering adopts the system of dry-hungand wet-lying in the construction of roof with steepslope, to save the construction period of about 24days (40%), seven-time manual work, wages forworkers of RMB 240 yuan/person/day, rentalexpense for tower crane of RMB 800 yuan/day, andto achieve the good effect of economic benefits ofabout RMB16 yuan/m2. Therefore, this newconstruction technology is worthy of popularizationand application.5.E-ISSN: 1817-3195[6] MODELING AND SIMULATION OFPARALLELPROCESSINGARCHITECTUREFORIMAGEPROCESSING January , Journal of June2007 Vol. 3 No. 1[7] USING MUTUAL INFORMATION ANDCROSS CORRELATION AS METRICS FORREGISTRATION OF IMAGESJournal ofTheoreticalandAppliedInformationTechnology (JATIT),June 2008 Vol4.
