Description
Technical field
The present invention relates to steel building industries, exempt from demoulding pour concrete using girder steel more particularly to a kind of steel building
Package structure girder steel antirust construction technique.
Background technique
Assembled architecture has obtained rapidly the extensive approval and receiving of society, and is promoted and answered rapidly in building field
With and assembled architecture its structural framing is at present still based on reinforced concrete frame and steel structure frame, and flooring is generally also
It is Cast-in-place concrete flooring, though there is reinforced concrete frame building in part to realize a degree of prefabricated construction but phase at present
To relatively difficult, and difficulty of construction is big for complex process.
And steel structure frame build opposite reinforced concrete frame build its construction assembly rate will be much bigger, it except basis,
Flooring, slope roof surface board are taken outside Cast-in-place concrete cast-in-site, and the Steel section members such as bearing beam, column and wall can all realize that dressization is applied
Work, building assembly rate and construction efficiency have obtained being substantially improved for substance, but its critical defect is exposed steel structure
Part antirust treatment is a problem, and traditional method is this outdoor, bridge, structures etc. relatively using brushing paint antirust treatment
For steel building no matter construction technology or later period antirust maintenance or it is relatively feasible；But steel member exposed for civil buildings
Safeguard it is extremely difficult to the harm of people and later period regular mopping antirust with painting layer antirust, its paint smell, also not
It is feasible, therefore to solve the problems, such as that the exposed component long-acting antirust of steel structure frame has of crucial importance in such a way that science is simple and effective
Practical significance.
Summary of the invention
The object of the present invention is to provide a kind of steel buildings to exempt from demoulding pour concrete package structure girder steel antirust using girder steel
Construction technology exempts from demoulding by being fixed with girder steel below the top flange of girder steel two sides and is laid with flooring cast-in-place concrete building floor crack with exempting to tear wave open
Card bed die pours concrete by exempting to fill concrete in demoulding and exempt to tear open in ripple plate bed die to girder steel, by steel building structural steel
Beam and all steel members are completely encapsulated in concrete the difficulty that the structural steel beam long-acting antirust of steel building is thoroughly solved without exposed
Topic.
The technical solution adopted by the invention is as follows: a kind of steel building exempts from demoulding pour concrete package structure steel using girder steel
Beam antirust construction technique, it is characterised in that include the following steps:
(1) structural steel beam is installed: the girder steel made being assembled installation in place as required according to construction drawing, fastening bolt
And it is welded with fixation；
(2) formwork angle steel is fixed: welding side is used in the stiffener plate of the top flange lower part two sides of girder steel length direction in girder steel
Formula is fixed with formwork angle steel；
(3) girder steel exempts from demoulding installation: girder steel is exempted from into demoulding by construction requirement and is mounted on formwork angle steel, is fixed with tapping screw,
And it is welded with exempts from demoulding positioning pin as required；Girder steel is exempted from demoulding installation principle by inner beam after first outer beam, and secondary beam is suitable after first girder
Sequence installation；
(4) exempt to tear open the installation of ripple plate bed die: being laid on flooring concrete placings with exempting to tear ripple plate bed die open in order by construction requirement
On formwork angle steel, and with tapping screw fixation；
(5) floor steel bar is bound: being exempted from demoulding and flooring concrete placings in girder steel and is installed and is checked conjunction with exempting to tear open ripple plate bed die
After lattice, two-way floor steel bar then has been bound by design requirement；
(6) mechanical pour concrete: having cleared up flooring sundries, then flooring is poured using mechanical pumping Commercial Concrete, in principle first by steel
Beam exempts from concrete filling tamping in demoulding and then smoothes out the casting tamping of flooring Cast-in-place concrete；
(7) concrete water seasoning: film water seasoning should have been covered by being poured after tamping smoothes out after flooring Cast-in-place concrete, reach after some strength by
It is required that carrying out next process construction.
Formwork angle steel uses Zinc-coated angle steel in step (2) of the present invention.
Step (2) of the present invention should also increase corresponding formwork angle steel stress as required and increase when stiffener plate spacing is excessive
Then strong fixing iron member welds each welding spot welding in fact.
Step (6) of the present invention will first be shored in steel beam bottom by the anti-disturbance of construction requirement setting before mechanical pour concrete, and
Conscientiously check before concrete is poured to demoulding, reinforcing bar etc. is exempted from.
The present invention, which is devised, exempts from demoulding for the girder steel of structural steel beam bottom outsourcing, the structure of part below cast-in-place walls plate
Structural steel beam antirust can be wrapped up after girder steel filling concrete molding；It is designed in girder steel along the top flange lower part two sides of girder steel length direction
The elongated formwork angle steel for having had formwork to act on, the girder steel for fixing steel beam bottom filling concrete exempt from demoulding and are laid with flooring casting
Concrete exempts to tear open ripple plate bed die.Elongated formwork angle steel is fixed in girder steel stiffener plate and props up by welding or other means
Modular angle steel stress enhances on fixing iron member.
Compared with existing construction technology, the present invention has the following advantages:
1, the present invention when flooring concrete placings be filled into girder steel exempt from demoulding and exempting from tear open ripple plate bed die it is interior after, can by structural steel beam and
All steel members are all wrapped in concrete without exposed, so that the long-acting antirust for thoroughly solving the steel member of steel building is asked
Topic lays a solid foundation for steel structure frame building in popularizing for building field.
2, steel building of the present invention exempts from demoulding construction technology using advanced steel construction itself stress formwork, is by setting
Meter require by the standard that factory makes exempt from demoulding install with very easy mode get well admittedly after can pour concrete, do not need by biography
System formwork way sets up support for shuttering and molded-in-place, die-filling and demoulding, has significantly simplified working procedure and has improved labor efficiency, until
Artificial work efficiency 80% is improved less, shortens the construction period 60%；Formwork steel pipe scaffold and building template is greatly reduced simultaneously to build
The usage amount and consumption built in construction are conducive to resource-effective so that project cost be greatly reduced.
