(2) ponding and laitance are cleaned out, and 70 thick walls and original structure concrete wall intersection and flooring constuction joint position chop hair;

(3) the pre-buried 70mm of flooring thick partition wall reinforcing bar joint bar, top board does not have embedded bar, needs bar planting.The bore position that bar planting method following (a) uses electric drill to demarcate on structural plane, pitch-row 400, door opening place suitable for reading pitch-row 200; Bar planting aperture ¢ 8mm, hole depth is 80mm; B () has been holed after, will blow clean in hole with inflator, with hairbrush, hole ambient dust is cleaned out.Ensure in hole, to reach clean dry; If moister in hole, must with unit heater to carrying out drying process in hole; C () adopts the bar planting of ¢ 8mm indented bars, first reach also fill in structure glue injection hole at 2/3 degree of depth during bar planting, at the bottom of the patchhole of Swiveling Rebar limit, limit, overflow aperture be advisable with a small amount of colloid, standing 72 hours to be solidified;

(4) single two-way ¢ 6mm200mm reinforcing bar, directly overlap with partition wall reinforcing bar joint bar or bar planting colligation, lap length >=300mm, on door opening, corner respectively adds 2 ¢ 6mm reinforcing ribs, length 600mm, the colligation of colligation employing 22# galvanized wire;

(5), after reinforcing bar binding, the gauze wire cloth of the steel wire lashing mesh 20mm × 20mm of diameter 1.5mm is adopted in the side of not formwork supporting plate;

(6) according to body of wall length, one side preparation polylith sizing wooden form, template adopts common old veneer and 50mm × 100mm flitch; Typified form 2720mm is high × and 610mm is wide, vertical wooden stupefied 300mm spacing, and position, turning configures separately negative and positive angle mould; According to played body of wall sideline inwards 10 ㎜ install template, every block template adopts timber wedge temporary fixed up and down; Messenger wire calibration template verticality, clenches timber wedge and fixes, and adds to support to fix;

(7) single surface formwork, now smears fine-stone concrete at twice, and first pass smears 30mm, smearing 20mm second time, playing in wall alignment 10mm as control foundation, often all over smearing pressure all from bottom to top using surrounding, smear press 2 hours off times with first pass for second time, smear for second time after pressing concrete, surface galling; Thinly smear interval after concrete and remove a mounted split pattern in;

(8) according to the wall sideline that on flooring, original structure metope, top board, bullet is good or 30 ㎝ metope control lines, on body of wall, make ash cake, ash cake spacing is not more than 2000mm, and employing 1:3 cement mortar is disposable 8 ㎜ that plaster on the surface that body of wall is two-sided;

(9) two-sided upper verticality and the planeness of body of wall is repaired, rear press-in grid cloth, at the 2mm that plasters on grid cloth, surperficial press polish.

(10) after mortar surface sclerosis, moisture-keeping maintaining 3 days.

After taking above technical scheme, beneficial effect of the present invention is:

Thin smear concrete wall have firmer than blockwork, not easily and between agent structure concrete produce crack, mass defect is few.
