Technological process:
Base cleaning, check and process → unwrapping wire and base course wall, thin portion look for rule → wallboard typesetting, matching board → installation wall Face thickness controls block and corner control strip → install special wallboard → holding clamp and stop → hard-foam polyurethane insulation material examination Preparation and examination pour → and hard-foam polyurethane insulation material prepares → pours the heat-insulation layer of hard-foam polyurethane insulation material → trimming molding Thin portion → the exterior wall surface decorative such as corner.
Key points for operation:
1. base cleaning, check and include with process: substrate surface should be dried, clean without greasy dirt.To existing original decoration Surface layer 5 (such as ceramic tile, mosaic or cement surface layer etc.), the present situation such as first should be corroded its adhesion strength, basic unit checks, And make record.The hollowing occurred, surface layer broken, loosening, aging, cracking should be shoveled down and clean out, fill out at polyurethane Fill in layer 6 casting process fills closely knit with polyurethane foam in the lump by damaged part
Surface dust and greasy dirt utilize scavenger specially to be carried out, and use clear water to cleaning position during cleaning Wash away, to avoid the abluent corrosion to basic unit, the complete construction that can carry out heat-insulation layer after surface air-dries to be cleaned. The cleaning agent used should be the cleaner special of neutral meta-alkalescence mating surface activating agent preparation, pH value typically should be 8~10 it Between, the abluent containing a large amount of fluorides must not be used or have the corrosive abluent of strong acid and strong basicity abluent.
2. unwrapping wire includes with typesetting:
Utilize theodolite, ribbon, horizon rule, construction line, level to control the instruments such as water pipe, structure wall 8 first sets Putting datum line, use the line of ink marker to eject datum line, take this as the standard, the survey carrying out vertically and horizontally control line sets.
Hang vertical thickness control line at negative and positive angle, use to hang and draw steel wire as exempting from hanging down of form removal block 4 i.e. PU cement plate installation Straight control line, controls, with theodolite, the perpendicularity that wallboard is installed, is fixed the bottom of cement plate after meeting the requirements.Horizontal control lines Arranging by architecture storey, every layer sets together.
Typesetting figure is made, the staggered interlocking in position, corner according to actual measurement building overall dimensions.At window hole corner, wallboard is not Must splice, should use monoblock wallboard cutting forming, wallboard joints should leave corner at least 200mm.Metope corner paving wallboard material Time minimum dimension should be greater than 200mm.
3. metope THICKNESS CONTROL block and corner control strip are installed.Use identical material polyurethane pre-in advance according to pouring thickness Stay block 7, polyurethane reserved block 7 size be the edge strip used by 20 × 50mm, edge sealing and plug be width dimensions 20mm, thickness all with The thickness of filling polyurethane layer 6, uses mounting method by the prefabricated polyurethane of prefabricated section, edge sealing and plug before special wallboard is installed Fix temporarily.Polyurethane reserved block 7 stickup quantity be 10~15/.
The installation of 4.PU cement plate.Place wallboard according to metope control line, use electric hammer according to the reserving hole on wallboard Boring, and uses scaffold 1, actuator 2 and gripper shoe and panel 3 to fix wallboard temporarily, drilling depth for enter original basic unit >= 50mm, then uses special mould clamp and stop to fix wallboard, and between wallboard, piece spacing is 1~3mm.
The most cast-in-place hard-foam polyurethane insulation material includes:
Dispensing: A material isocyanates, B expect polyhydric alcohol.Different work environment and job requirements according to job site need to add Enter to assist material, such as: (low boiling, lower thermal conductivity, volatilization of being heated forms gas, is easily wrapped to form by polyurethane feed liquid foaming agent Foam) the catalyst speed of primary response (control), stabilizer (controlling uniformity coefficient and the size of abscess of abscess), fire retardant (being used for taking precautions against insulation material burning).
Use depletion of QI high pressure polyurethane placing installation, first original retained material in equipment is discharged, and treat that discharging is normal After can pour.Must not occur when pouring that certain some pouring material is too much, walk to expect reiteration, the problem that leak source pours, pour every time THICKNESS CONTROL is 30~50cm.Casting process controls the amount of pouring, make polyurethane pour to mounted wallboard suitable for reading lower 5~ 8cm.After pouring complete 15min, installing of lower one wallboard can be carried out, should clear up to have watered before installing lower one wallboard and build up The heat-insulation layer redundance of type, it is ensured that wallboard joints position is closely knit by filling polyurethane.
In casting process, make the admission pressure phase of A, B material pipe in mixing chamber by adjusting the air pressure valve of air compressor With, to reach to form the fullest hard bubble body in A, B material is blended in template cavity in 1:1 ratio.
6. plate seam processes.Ban Mian basic unit after pouring should clean out, contamination-free, and uses electric angle grinder etc. to plate Seam and position, warping part, corner, local carry out the most smooth.After scum silica frost is cleaned out, re-use single-coated foam and plate seam is pasted Sealing treatment, single-coated foam base material is alkali resistant glass fibre open weave cloth (width 50~70), and overlap joint, not less than 80, must not wrinkle Wrinkle, decortication.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting Involved claim.
