The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
The standard width of a room in an old-style house of certain housing construction body of wall is of a size of 3m*4.5m; Floor height 3m, following with the concrete structure and the manufacture process of this compound concrete shear wall of precasting of the present invention side fascia that designs and make: the height of A cementitious material topping is 3m, and width is 4.5m; Make on the in-plant platform template and form; In the present embodiment, adopting high strength gypsum, cement, flyash, glass fiber muscle and waterproof agent mixture is cementitious material, the mass fraction ratio; Gypsum is that 60 parts, cement are that 20 parts, flyash are that 18 parts, glass fiber muscle are that 1 part, waterproof agent are 1 part; Its process is earlier at platform template pave high strength gypsum, cement, flyash and waterproof agent compound, repaves afterwards into the glass fiber muscle, and wipeing off then and forming thickness is the A cementitious material topping of 15mm.
With size and A cementitious material topping size dimension quite, shift to an earlier date the prefabricated light-weight thermal insulation material layer that has long and short dowel and be placed on the A cementitious material topping, jam-packed flattens and forms thickness is the 85mm light-weight thermal insulation material layer; In the present embodiment, light material is a polyphenyl plate; Long and short dowel in the light-weight thermal insulation material layer is by regularly arranged layout, and short dowel is the square plastic pipe, and the mouth of pipe is of a size of 10mm*10mm, and length is 120mm; Long dowel is the square plastic pipe, and it is 250mm that the mouth of pipe is of a size of 15mm*15mm length, interspersed batten in the pipe, and the two ends of pipe are shaped on 12 lobe umbrella heads respectively.The prefabricated process of light-weight thermal insulation material layer that has long and short dowel is: earlier long and short dowel one end is scalded the palpus of falling umbrella head, two short dowels and a long dowel are passed at parallelly connected eyelet, and stick with glue knot; By the scale of indicating on the operating desk, on light heat insulation material, scald the hole, wear long and short dowel; Through a half, daub pierces into and squeezes sternly the light heat insulation material turn-over; The long and short dowel blanching of the other end is fixed to the head of falling the umbrella, and the light-weight thermal insulation material layer plate is piled up subsequent use.
On light-weight thermal insulation material layer, place the good screw thread iron reinforcing bar shelf of welding, and around the reinforcing bar shelf, fix the 2 layers of group's template of living, build the thick concrete of 145mm afterwards and form the reinforced concrete shear wall stressor layers.Last, left and right three edge of reinforced concrete shear wall stressor layers is than light-weight thermal insulation material layer edge indentation 300mm; Directly move back the platform shape thereby form; The space of welding connection node reinforcing bar and cast position of joints concrete when connecting between wallboard; Stool leg shape is made in reinforced concrete shear wall stressor layers and C cementitious material decorative layer bottom, reserves the space that is welded to connect reinforcing bar of long 1500mm, high 300mm at interval, and the hole of the pour concrete of diameter 100mm.
Expose the B cementitious material that partly paves directly moving back platform position light-weight thermal insulation material layer, be pressed into the glass fiber muscle again, wipe off and form the thick B cementitious material of 10mm layer.The component of B cementitious material layer, proportioning and A cementitious material topping component, proportioning are identical, play the effect of protection adiabator layer.
The upper and lower, left and right of reinforced concrete shear wall stressor layers are stretched out the long reinforcing bar of 700mm on four sides, reserve enough lapped length of steel bar, and upper and lower reinforcing bar is connected with floor bar weldering knot; Left and right reinforcing bar is connected with adjacent wall board reinforcing bar, node place vertical reinforcement weldering knot.The C cementitious material that on the reinforced concrete shear wall stressor layers, paves, the component of C cementitious material layer, proportioning and A cementitious material topping component, proportioning are identical, C cementitious material thickness 15mm.C cementitious material layer will long dowel many lobes umbrella head imbed after, be pressed into the glass fiber muscle, wipe off and form C cementitious material decorative layer.
After precasting composite shear wall side fascia made, it was steam-cured or after high temperature season natural curing, obtain precasting composite shear wall side fascia to go into kiln.
In the middle of the light-weight thermal insulation material layer upper and lower faces of precasting composite shear wall side fascia, offer the U-shaped groove, slot opening 40mm, dark 40mm; In the middle of left and right two sides, be opened in the v-depression of wallboard, slot opening 40mm, dark 40mm.
During installation, in waiting horizontal U-lag of plate, paste olive shape light heat insulation material weather strip, in waiting vertical V-shaped groove of plate, paste rhombus light heat insulation material weather strip, shop coated plate seam putty.When precasting composite shear wall exterior wall comes plate to install, the reinforcing bar of the position of joints between welding precasting composite shear wall side fascia and the precasting composite shear wall side fascia, between precasting composite shear wall side fascia and the floor.
With precasting composite shear wall side fascia Zhi Jiedian place permanent formwork, cast position of joints concrete is accomplished wallboard and is installed.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
