4), according to constructional column center line, weld T-shaped spacer bar at the main muscle of the constructional column position of 4 ~ 6cm eminence on constructional column post root, in order to control constructional column sectional dimension and axial location (position-limiting action);
5) outside constructional column post skin, about 5mm pastes wide sponge strip, tight to ensure end opening and seam;
6) installation constitution column template, constructional column template comprises that post inner cross type supports and post surrounding exterior sheathing;
7) installation constitution post tie, the steel pipe that wherein styletable uses the screw combinations butterfly padlock welding with horizontal bar firmly to reinforce flitch back cord carries out formwork reinforcement;
8) constructional column template is proofreaied and correct, is reinforced;
9) cast post concrete;
10) form removal in the time that constructional column intensity reaches design strength, picks out at pre-buried Screw arbor with nut at both-ends cut-off part the pit that 8 ~ 12mm is dark, cuts off along constructional column surface the Screw arbor with nut at both-ends stretching out, and to the antirust processing of Screw arbor with nut at both-ends head after cutting off.
Press such scheme, in described step 5), sponge strip width is 18 ~ 22mm.
Press such scheme, described step 6) specifically comprises: first erection column inner cross type supports, back mounting pole surrounding exterior sheathing, the corresponding Screw arbor with nut at both-ends extended position welding with horizontal junction muscle muscle of punching when batching; Constructional column template is installed by logical organ timbering, and both sides column template is first installed, calibrated, draw again after reinforcing logical line install in the middle of each column template.
Press such scheme, in described step 7), tie comprises that flitch back cord, steel pipe and anti-skidding butterfly buckle, installation process is specially: the flitch back cord of following closely 50mm × 100mm in constructional column template, the about 100mm of spacing, be buckled in and on Screw arbor with nut at both-ends, tighten fixingly with the steel pipe of two external diameter 48mm wall thickness 3.5mm and the anti-skidding butterfly of twice along vertical flitch back cord direction, tie vertical interval is 300 ~ 500mm.
Press such scheme, described step 8) specifically comprises: first proofread and correct, reinforced both sides column template by constructional column axis, then hang up logical line and proofread and correct intermediolateral column template, column template timing must guarantee that four sides is on same straight line, perpendicularity deviation, misalignment of axe, adjacent two surperficial differences of height, surface smoothness and cross section inside dimension are all controlled within the scope of job specfication tolerance.
Press such scheme, in described step 10), the antirust processing of Screw arbor with nut at both-ends head is specially with cement mortar floating.
Compared with conventional construction method, beneficial effect of the present invention:
1, directly by horizontal body of wall tension rib and the welding of constructional column wall-punching pair-pulling threaded spindle, then live the steel pipe of constructional column end reinforcing flitch back cord with this screw combinations butterfly padlock, utilize the pulling force of horizontal bar to provide constructional column end to reinforce required horizontal restraint, fundamentally solve constructional column formwork and reinforced the problem that must punch on masonry structure, avoid masonry structure to cause the drawback of body of wall globality and compression strength step-down because constructional column formwork punches, make masonry globality and compression strength higher, construct more simple and efficient;
2, template construct, installation are all carried out operation by the quality requirement of plain form, shuttering supporting adopts the reinforcement system of flitch back cord combined steel pipe with screw rod drawknot, compare with traditional masonry wall sleeve-penetrating drawknot method, simple, this technique is gathered materials on the spot, expose the direct cutting process of screw rod, relatively the construction method template strength of other building block moulds is higher, more economical.
