Figure, can respectively in factory process customization or Site Welding built-in fitting, and beam column built-in fitting is formed by pre-embedded steel slab and welding of peg,
Peg can increase substantially the bonding bond stress between built-in fitting and concrete；Strict construction in line with the drawings is answered in welding position, needs accurate
Reliable, level weld seam requirement is smoothed during welding, must not there is the weld defects such as stomata slag inclusion, it is found that defect should be repaired in time.
(3) beam column installation of embedded parts：After floor girder and board formwork erection is good, using tower crane by metal embedded part handling to building
The corresponding pre-buried position of sandwich beam, it is desirable to all components must be tied up firmly, special messenger should be arranged to command in lifting process；For true
Protect built-in fitting to be accurately successfully put into beam, after beam bottom board is installed, installation of embedded parts position has been marked according to design in-depth drawing
Put, first, beam concave flute profile built-in fitting is in place, and carry out fixation, prevent displacement；Treat that beam levels cage bar is placed
After good, beam main tendon is erected, arrange special messenger that built-in fitting is accurately placed into beam-ends relevant position in time, carry out interim fixation；Meanwhile,
With wood block filler Zhi Qiliang upper stratas cage bar, facilitate beam stirrup to pass through embedded board downside colligation and fix, wherein, in beam at built-in fitting
Stirrup should be through colligation in concave tooth seam；In addition, post built-in fitting should be placed in advance in before column tie-bar colligation, subsequent colligation stirrup, then
It is welded and fixed；After reinforcing bar colligation is complete, built-in fitting position, upper and lower built-in fitting center alignment, it is ensured that steel branch should be again checked
Support is arranged in perpendicular, and installation of embedded parts error should be less than 10mm when installing built-in fitting, after confirming that installation is qualified, side
Can casting concrete.
(4) slab column concreting：During concreting, built-in fitting answers vibration compacting at position, can match somebody with somebody and share crooked chisel
Tamping, should not encounter built-in fitting when vibrating；Pour before finishing rear initial set, carried out receiving light treatment with wooden float long, while should be 12
Plastic sheeting moisture-keeping maintaining is carried out in hour in time, curing period is no less than 7 round the clock.
(5) metal damper, steel joist welded and installed：First, according to design in-depth drawing, respectively in steel joist upper table
Built-in fitting bottom plate has marked the position line of damper 1 in detail in face, beam, and damper 1 is placed into steel by operating personnel on flooring
Joist upper surface relevant position, is corrected further according to position line crowbar to the position of damper 1, makes bottom position and position line
Overlap；After the position correction of damper 1 is errorless, will be first welded and fixed between damper 1 and steel joist with welding machine, make steel joist with
Damper 1 is connected as a single entity, and afterwards, the solder side polishing to built-in fitting bottom plate in beam, it is ensured that welding quality is lifted using self-control
Machine and human assistance are promoted to the steel joist and damper 1 that are welded at beam built-in fitting bottom plate respective markers position, school
Finally it is welded and fixed after positive position.
(6) gusset plate is installed：First, original structure beam axis is checked, again the good line of ink marker of bullet, in strict accordance with in-depth drawing
Location dimension is using laser level scene flag node plate placement location and carries out mark；Afterwards, during welding node plate, should be true
Protect gusset plate installation deviation in allowed band, take spot welding to fix temporarily, with post-equalization gusset plate position, it is errorless after carry out again
It is welded and fixed.
(7) support is installed, fixed：With truck crane by corresponding support frame handling to suitable installation site after, according to
Respective design deepens drawing, and scene has marked bracing members lower port notch size positions, with Manual cutting gun to support rectangular square tube
Cutting fluting；In order to ensure bracing members in vertical plane, first blow-down bit line is answered before installing, and (position line is gusset plate center line in beam
Projection line on cylinder)；Afterwards, sling bracing members by agent structure with bottle gouard moved by hands, regulation up and down position to designing
Position, by support rectangular square tube otch insertion gusset plate, upper end is carried out by pulling support and prizing support front-back
Fix in place and temporarily；Support two ends are corrected again after temporarily fixed, the lower end node of support are first welded after correction, then weld
Connect end node；If the spacing between product length and gusset plate has error, can be disappeared by on-site cutting or the method for welding
Except error, confirm that errorless rear determination good position is welded and fixed again.
(8) connecting node detection：After whole brace type metal damper installation procedure construction is finished, bracing members are carried out with knot
Structure connecting node weld seam detection, the I and II weld seam of design requirement complete penetraction and fusion in welding should carry out internal flaw using ultrasonic examination
Inspection, should detect, testing result should reach code requirement using radiographic inspection when ultrasonic examination can not be judged to defect.
(9) anti-corrosion, fire prevention treatment：Weld seam should carry out the polishing all of welding slag of removal, should carry out flushing polishing during polishing, connect
Head point should be in smooth state with base metals, should not there is out-of-flatness part；Then, the position that paint is damaged is repaiied
Mend, the anti-corrosion of node connecting elements uses epoxy zinc-rich paint, film thickness to be not less than 12mm, and Site Welding part will weld
The brushing paint as early as possible after；Finally, anticorrosive construction carries out fire prevention construction after the completion of checking and accepting according to design requirement.
(10) support connecting portion filling wall is built by laying bricks or stones：In wall transverse direction tension rib construction and Constructional Col-umn Construction, using even
Connect folder to be connected with support both sides tension rib, it is ensured that tension rib is elongated；When reinforcing bar encounters upper node, can be direct by constructional column reinforcing bar
It is welded in the end face reinforcing plate of gusset plate；When wall plastering, one layer of galvanized steel wire netting, zinc-coated wire are done in support zone
Net zinc-coated wire and nailing are fixed with wall, it is ensured that wall plastering does not ftracture.
