Enumerate enforcement construction method
(1) laying gangboard, reinforcing
Require to determine plagioclase and the width of stair according to design drawing, further according to on-site actual situations, plank sheathing is cut out
Cut, process.Should be required according to scheme before laying gangboard, during to stair template integral reinforcing, the split bolt using be carried
Front preformed hole, preformed hole lengthwise position is to contact every 700mm arrangement one mouth along gangboard plagioclase direction with gangboard from terraced beam
Road, per pass is 2 holes.2 preformed hole lateral attitudes are respectively at stair each edge 300mm.
Start should first gangboard support system be reinforced when laying gangboard template, its reinforcing mode adopts flitch as secondary
The additional steel pipe of Os Draconis, the combination of jacking carry out diagonal brace, and flitch (secondary joist) is flapped toward along gangboard plagioclase direction, and from gangboard edge
Play every spacing 250mm and arrange a flitch, arrangement principle is to ensure that gangboard two ends are respectively mounted flitch and middle span flitch spacing not
More than 250mm(note: overlapping mode can be adopted when wall scroll flitch length is inadequate, and lap-joint must have diagonal brace steel pipe to withstand, two ends
Flitch each stretches out diagonal brace length of steel pipe and is not less than 150mm).Diagonal brace steel pipe support angle preferably becomes 90 degree, and steel with gangboard bottom surface
Bottom of the tube need to fall in lower floor's stair step inner corner trim joint (the inner corner trim position that the level that is supported on is marked time with vertical handing-over of marking time).
The supporting steel pipe contacting with jacking adopts 2 steel pipes to merge, and supports main joist as the integral reinforcing of stair.Diagonal brace steel pipe adds
Gu when, supporting steel pipe first across arranging together at mouth 700mm for contacting along the terraced beam of gangboard plagioclase direction distance with gangboard, afterwards
And spacing 1400mm arrangement is together, and last is across cannot be greater than 700mm, and per pass joins 2 jackings, steel pipe transverse for 2 steel pipes
Position is to be arranged at respective gangboard edge 250mm respectively.
(2) colligation gangboard reinforcing bar, the terraced beam rubbish of cleaning, bullet stair side loft
Start gangboard reinforcing bar binding after the completion of gangboard model sheetinstallat, reinforcing operation, should clear up immediately after the completion of reinforcing bar binding
The rubbish of lower mouth ladder beam bottom, then requires to carry out unwrapping wire to stair gangboard according to design drawing, then carries out taut line with cotton thread, with
Control the error causing when marking time model sheetinstallat.
(3) step plate, reserved dentation shear wall formwork are made
Required to horizontal step plate, vertical step plate, shear wall (Vierendeel girder) and stair side form sawtooth according to design drawing
Shape preformed plate carries out blanking in advance, processing.When operating this step, it should be specifically noted that deduction template thickness, determine horizontal step plate
It is connected with each other the connected mode of mode and step plate and shear wall zigzag template edge with vertical step plate.The suggestion of this link is adopted
Use following connected mode: 1, horizontal step plate end replaces vertical step plate top；2nd, vertical step plate bottom substitution level is stepped on
Step plate root；3rd, the left and right end of vertical step plate replaces shear wall (Vierendeel girder) and stair side form zigzag reserves template end；
4th, the left and right end of horizontal step plate replaces shear wall (Vierendeel girder) and stair side form zigzag reserves template end.
(4) shear wall side form is installed, step plate, preliminary reinforcing are installed
Install shear wall side form when need to according to the relative space position of the position adjustment zigzag template of position line, ready after
Shear wall side form is reinforced, reinforcement means is identical with common shear-wall strengthening method.After the completion of shear wall side form is reinforced, just
Proceed by the installation of step plate, install and should first vertical step plate of mouth start to install first from stair during step plate,
First horizontal step plate is installed again, step plate is supported with reinforcing bar stirrup, to ensure the thickness of gangboard and the position of step plate.As
This analogizes, and tentatively should be fixed using iron nail during installation, and iron nail consumption will not arbitrarily be swung with ensureing that step plate hand push is pushed violently
For principle.
(5) integral reinforcing, stay steam vent
Integral reinforcing should be carried out after the completion of step plate installation, reinforcing operation, should be first according to difference before carrying out integral reinforcing
The gangboard slope of stair requires to place flitch in every ladder level plate face of marking time, and flitch needs horizontal positioned and flitch Edge Distance is marked time
Depending on edge relative position need to be according to stair slope, its principle is: flitch height (mm)/Edge Distance flitch outer ledge of marking time
Distance (mm)=gangboard slope.After flitch is fixing, using electric drill, step plate is holed, in view of operation before has been entered
Go the boring at staircase boards bottom, therefore using this hole, from the bottom up step plate can have been carried out with perforate, drill bit direction should be vertical
In stair swash plate direction, aperture is 16mm, after the completion of drilling operating, split bolt is inserted in preformed hole, then 4 length are
6 meters of steel pipe is integrally reinforced to stair along split bolt both sides along stair swash plate direction.Should after the completion of integral reinforcing
Steam vent is reserved to step plate, steam vent is arranged on horizontal step plate, each setting 3-5 of marking time is advisable.
(6) rubbish around cleaning
Treat above-mentioned all process steps all complete and check errorless after, (include on Bars In Poured Concrete Slab) in the range of 2 meters around reply
Rubbish is processed in time, and by rubbish, the garbage-cleaning preformed hole from stair swash plate bottom surface is discharged with the mode of bath.
(7) close garbage-cleaning preformed hole
Just the garbage-cleaning preformed hole that stair swash plate can be reserved after the completion of garbage-cleaning is closed, if necessary visually
Additional two steel pipes of concrete condition are individually reinforced to the template of closing portion.
(8) casting concrete
Need before casting concrete to moisten template with water, the slump of concrete controls in 180mm, and concrete is from rest
Platform is continuously poured into stair seam, and uses vibrating head vibration compacting.When vibrating, the vibrating head of selection of small is vibrated, and
Vibrated in template surface of marking time with another vibrating head while gangboard concrete vibrating, make all in the holes of giving vent to anger whole
Till flowing out concrete grout.
