Embodiment 1
Fig. 1 is typified form processing and fabricating back elevation.Fig. 2 is typified form processing and fabricating 1-1 section profile.The wallboard template 4 of first determining cast-in-situ concrete, requirement for bearing capacity when can meeting concreting, can ensure that again concrete reaches clear-water concrete effect, generally selects the high-quality veneer that 12mm is thick.Template 4 adopts keel 1 and 2 to reinforce, and keel 1 are directly connected with iron nail 3 with 2, keel 1 and 2 according to outside concrete wall Thickness Checking, select rational shuttering supporting reinforcement system.
Fig. 3 is typified form processing and fabricating wall decorative effect modelled after an antique front elevation view.First carry out the template typesetting of wall decorative effect modelled after an antique according to outside concrete wall, draw the template drawing of wall modelled after an antique, the brick face size of wall modelled after an antique is determined according to Integral decoration effect, is generally selected the brick form of 128 mm × 254 mm × 508mm, mortar joint 25mm.
Cast-in-situ concrete of the present invention wall construction method modelled after an antique, specifically comprises the following steps:
1, select the template of suitable cast-in-situ concrete wall modelled after an antique, draw detailed Site Template processing and fabricating drawing, processing and fabricating typified form.Site Template work flow: modeling plate--, Wooden Batten and the screw hole → numbering → stacking of lines → Wooden Batten thicknesser → nailing template keel anyhow → nail lines → brill.First template is screened, ensure that thickness of slab is even, plate face is without obvious concavo-convex, stripping phenomenon, and Diagonal Dimension deviation is not more than 1mm.Next is selected Wooden Batten and carries out S4S, and guarantee contacts closely with template and reinforcing steel pipe.Then eject the lines position line according to turning over master drawing size at plate face, opsition dependent tailor's tack upper semi-circle lines, half-round moulding nail system need be close to template, ensures that lines are without the defect such as rake angle, hollow.Then according to Screw arbor with nut at both-ends setting space and position, get out screw hole, wallboard template screw rod hole location is all arranged at lines place.Finally be numbered and stack neat machining typified form according to typesetting and pre-splicing suburb fruit.
2, concrete mix is determined, on-the-spot processing and fabricating clear-water concrete wall member model modelled after an antique reaches formally construction after designing requirement.Concrete color is mainly determined by cementitious material cement and aggregate, the particularly color of cement, through Mix Ratio Test repeatedly, determines the description of concrete cement, aggregate and admixture, after raw material are selected, according to the member model of certain ratio field fabrication concrete wall modelled after an antique.Cement special holding vessel is set in concrete mixing process, avoids polluting, do not convert concrete cement, aggregate and admixture description midway.
3, cast-in-situ concrete wall form modelled after an antique is installed and is reinforced.Template flow of installation: inner side template places → adjusts → wears Screw arbor with nut at both-ends → installation to reinforce exterior sheathing → bracing wire adjustment → inner side template and reinforce fixing → template and check and accept.According to the typesetting of outside concrete wall template, figure spells mould, and from the bottom to top, by edge or the horizontal spelling of one end order, first inner side template is fixed in fixing outside again.In order to improve the effect of clear-water concrete, shuttering supporting split bolt adopts detachable split bolt, and the place that split bolt and template are joined adds the valve rubber that 10mm is thick.Formwork edge joint place iron nail constant spacing is not more than 15cm.When template processing and reinforcing, guarantee that template thickness+Wooden Batten thickness+steel pipe erects stupefied thickness, must equate at grade, to prevent that stagger in formwork edge joint place in the time that support is set.For ensureing that hanging, swollen mould phenomenon do not appear in constuction joint place, construction is when top plate, and stay and establishes a plate and do not remove at constuction joint place.When concreting, arrange special messenger on duty, find to become flexible, be out of shape finishing in time and reinforce.
4, concreting.Before concreting, constuction joint is processed: dabbing → cleaning → moistening → mortar four procedures lay cement.After concrete initial set, by the concrete dabbing on constuction joint surface, reject loosening stone and surperficial laitance layer, then clear up cement paste and the iron rust of rubbish and rebar surface.The moistening constuction joint surface of first sprinkling water before concreting next time, then spreads the thick cement mortar identical with the interior composition of concrete of one deck 50mm, then disturbing concrete.When concreting, strictly control match ratio, arrange special messenger's concrete mixing plant on duty, guarantee concrete pouring quality.The segmentation of cast-in-situ concrete wall wallboard modelled after an antique is built, and builds to the other end from wallboard one end, and inclined-plane natural layering, vibrates layer by layer, continuous placing.Vibrating head is accomplished " fast inserting slowly dialled ", will insert lower-layer concrete 50mm left and right while vibrating upper layer concrete, to eliminate two bed joints, before lower-layer concrete initial set, vibrates, and carefully vibrates, and anti-leak-stopping shakes and shakes less, avoids honeycomb, pitted skin and cold seam to produce.The concreting of wallboard end face to wiping one's face after absolute altitude, press polish, first concrete surface is taken off flat with spade, smear again thick flat with wood, after concrete reaches some strength, then smear cement will be extruded with wood, use iron plate press polish, before concrete initial set, carry out secondary press polish, closure surfaces is received water crack seam, and concrete finish is increased, and perception strengthens.
5, form removable.When stripping, can not overexert, can not large area prize, to ensure that concrete surface corner angle are excellent.Supporting steel pipe within complete latter second day, is removed in concreting and steel pipe is perpendicular stupefied, the 4th day stripping.Template segmentation is removed, and stay and establishes a template and reinforce steel pipe and do not remove at each constuction joint place, to ensure that hanging phenomenon does not appear in constuction joint place.That after dismounting program is generally, props up first tears open, after first propping up, tears open.Template is torn rear block-by-block transmission open, must not throwing, clean out in time, and plate face brushing remover, then neat by specification classify and pile up, so that turnover is used.
6, concrete curing.Concreting is complete, generally in 12h, covered, and water seasoning.After form removal, cover water seasoning and must not be less than 14 days.
