The construction method of installation that the full assembling of the present invention can dismantle building structure can use following step:
Ground is carried out according to construction file in working-yard, ground is provided with water and shakes layer of sand 16, water is shaken and is laid buffering extruded sheet 15 on layer of sand 16, then circle of drilling as requested pile foundation hole 1, bed course is carried out according to predetermined absolute altitude bottom pile foundation hole 1, then being steadily fit in pile foundation hole 1 by pile foundation 2, level is tamped;
Base beam 3 is arranged in pile foundation 2, in pile foundation 2, pre-embedded bolt 4 the other end passes the PVC sleeve in base beam 3 pre-opened hole and reserves certain length bolt above base beam 3, the other end of pre-embedded bolt 4 is fixedly connected with set nut 6, bolt and web plate fixing and locking base beam 3 and pile foundation 2 is used after levelling capturing, yi word pattern web plate is used between middle portion base beam 3, as shown in Figure 3, nook base beam 3 vertical lap seam docking uses L-type web plate to connect, as shown in Figure 4, gap between base beam 3 uses foamed glue to be filled with a sealing, it is provided with thermal insulation layer 14 outside base beam 3 and pile foundation 2,
Laying one layer of moistureproof linkrusta above base beam 3, then carry out prefabricated housing structure installment, installation order installs load-bearing gable body of wall 9 again for first installing load-bearing front-back wall body of wall 8, then installs partition wall body of wall 11 between load-bearing, then installs floor plates 10 or roof boarding;
Use lifting equipment by load-bearing front-back wall body of wall 8, load-bearing gable body of wall 9, with partition wall body of wall 11 lifting puts in place between load-bearing, double end right-hand thread screw mandrel is worn until body of wall bottom is locked in cavity above the pre-opened hole of body of wall height direction, double end nut 5 is used together to lock extremely by pile foundation 2 pre-embedded bolt 4 the other end and the double end right-hand thread screw mandrel the other end, reach centering fastening, look for just afterwards by dead for bolt lock in body of wall top fixing between body of wall, use web plate fastening between neighboring walls, after between body of wall, the flexible gap of vertical direction uses foamed glue to be filled with a sealing, the perpendicular upright seam recycle silicon ketone weather-resistant glue in body of wall outdoor is filled, the perpendicular upright seam in body of wall indoor and locking cavity use foamed glue are filled with a sealing after striking off again with cloth matter Pressure sensitive adhesive tape adhering and sealing,
Floor plates 10 is laid in load-bearing front-back wall body of wall 8, load-bearing gable body of wall 9 reserve partition wall body of wall 11 top between groove and load-bearing, after the Inner bolt holes 12 of floor plates 10 pre-opened hole and each body of wall top is aligned fastening with double end right-hand thread thru-bolt, the double end right-hand thread screw mandrel of the double end right-hand thread thru-bolt and second layer body of wall that expose floor plates 10 part after fastening re-use double end nut carry out centering locking be connected.
Can complete with double end right-hand thread thru-bolt is fastening after the Inner bolt holes 12 of roof boarding (individual layer house claims floor plates 10 to be roof boarding) pre-opened hole and each body of wall top is aligned by final step according to the method described above as only built individual layer house.
If desired build multilayer house, namely repeat according to above-mentioned installation method upper strata each portion body of wall to be installed until top layer, house building can be completed.
Wherein thermal insulation layer 14 is the fire-retardant heat insulation plate that fire-retardant styrofoam or other thermal conductivitys are little.
Above-mentioned body of wall can leave door, window 13 structure when prefabricated, installs door, window after house building completes, and the gap of body of wall and door, window adopts polyurethane foam glue to fill, and re-uses silicone weather resistant glue and fills.
Multilayer needs stair in house, and stair adopt in Steel Concrete stair prefabricated component, steel beam column or Wood member, Steel Concrete stair prefabricated component, stair steel beam column or Wood member and body of wall establishes beam post part and floor plates 10 inner bolt to be fastenedly connected.
Housing roof need to do WATER REPELLENT, and roofing steel beam column can stretch out bolt with roof boarding and be connected, and can lay perlite at roofing and again do isothermal holding before or after laying color steel, ceramic tile or terra-cotta.
