Abstract
The invention discloses a construction method of a special-steel concrete combination structure oblique wall mould frame; the construction method of a frame body is that channel steel is welded on a steel reinforced concrete column to form a cantilevered frame body which can act as the security preservation of operations as well as a supporting system of a die plate; and mirror boards are assembled on the site to form a bigger die plate which is hoisted integrally and ascends with a working layer floor by floor. The construction method has high-efficiency construction, convenient operation, simple technique and high safety factor. The adopted separate unit cantilevered frame body has a firm and safe frame body, lighter dead weight and larger bearing capacity. Material is saved by erecting a globally-stressed space truss structure with ordinary steel pipes, and the turnover of the die plate is increased by assembling ordinary mirror boards to form a bigger die plate.
Description
Technical field
The present invention relates to field of civil engineering, relate to the construction technology of template and support body, particularly the concrete composite structure inclined wall mould base engineering construction method.
Background technology
Further investigation along with development of times and building structure field, occurred large quantities of building structure that are different from conventional theory in the architectural design, its medium dip high level/high-rise buildings moulding has obtained architect's favor with its grand construction scope and unique visual effects.Because this structure construction work condition abnormality complexity, Mechanical Builds is various, space conversion, intersection, broken line node are more, body of wall tilts, corner structure is more, bring many difficult problems for the stability and the safety of structural system in the construction, brought difficulty particularly for the installation of setting up with template of scaffold.
The present common console mode support body or the support body of encorbelmenting of building trade, the construction effect is lower, and material usage is bigger, and can't solve the construction difficult problem of special construction; Common template system or climb the system complexity, cost is high.
Summary of the invention
The object of the present invention is to provide a kind of job practices of reinforced concrete composite structure inclined wall mould base, this job practices has improved the construction effect effectively, reduces engineering cost.
Technical scheme of the present invention is achieved in that
The installation of template:
1) template processing
According to setting type determined template size, with countersunk head screw the mirror board of standard is fixed on to piece together on the wooden back cord and makes large form, vertical back cord adopts 60 * 100 lumps of wood, and decide the bamboo film at the lumps of wood back side, horizontal back cord employing 5# channel-section steel, spacing 500mm; The template edge joint position is closely knit with glass cement;
2) locate unwrapping wire, determine the position and the size of per pass body of wall; The body of wall position is checked in inspection;
3) formwork hoisting
The template that configures is gone into mould with the tower crane lifting along slideway, form joint is managed everywhere: the template end opening installs the employing mortar levelling first, secondary installing is covered mouth, highly be 50mm～100mm, paste two-sided tape, seam is pasted two-sided tape between template, adjacent rough ground connects with bolt, typified form is adopted in the bight, adjacent forms is done tongue and groove clasping joint close, steel encloses the purlin joint to be strengthened with two steel pipes, through-wall bolt overcoat PVC plastic pipe and leakproof plug, and the position, turning is welded on three section header type through-wall bolts on the reinforced concrete column;
4) formwork reinforcement
Reinforcing in time puts in place after going into mould; The Template Location muscle adopts welding φ 16T shape reinforcing bar control on reinforced concrete column, beam, carry mould before, in advance positioning bar is controlled to the position of formwork erection, 1～1.5 meter of welding positioning bar spacing according to control line;
5) form removable and climbing
Form removable: when a construction layer surface construction finishes, after the concreting 24 hours, wall form can become flexible through-wall bolt, after 3 days, when top possesses the formwork condition, hang up properly tackles in advance on top, and pretension hangs the mould rope, connect to live template with leading screw after, remove through-wall bolt and template successively, promote rear lower and prop up pad with bracing frame and flitch, top and reinforced concrete column are done interim drawknot, and in time inner formword and its are fixed with through-wall bolt;
Set up support body:
1) welding channel-section steel
The encorbelment specification of channel-section steel of selection, the general 16# that adopts, length is at 1.8～2.2 meters, wherein being not less than 0.5 meter stretches in the body of wall, the residue length of encorbelmenting, girder steel is welded on the steel corbel upper surface, and spacing is not more than 4.5m, the beam outer end of encorbelmenting is welded the steel bar end of two ф 25 respectively, and company's wall drawknot of scaffold and building adopts steel pipe to weld screw rod through walls by screw hole through walls and body of wall ways of connecting:
2) set up the frame of encorbelmenting
Scaffold selects for use ф 48 * 3.5 steel pipes to set up; The vertical rod longitudinal pitch is 1.5 meters, laterally is the triangular form shape, goes on foot highly 1.8 meters, and the first step is set up into inside and outside truss with steel tube fastener, and lower edge is set up leger one; The vertical rod of installing on girder steel is set up into monolithic truss-like main frame with steel tube fastener, and bridging is completely taken in the support body outside, and per step is provided with steel tubular handrailing;
Before setting up, reinforce and utilize the scaffold of bottom, longitudinally on the girder steel upper berth leger is set, upright earlier inboard followed by the plug-in mounting vertical rod, the big or small cross bar on top is installed in upright again outside vertical rod, upwards progressively sets up again;
The same step, about two legers, leger joints staggered mutually, after leger is put up, little cross bar were installed, and its two should be stretched out more than the 10cm of leger outside, and same step vertical equity difference of height must not surpass 2cm;
3) safety net, frame plate are laid
After scaffold is put up part, the bottom of support body and side-closed, lay frame plate more in the above with Dense mesh screen; When the enemy spreads, under every plate termination, little cross bar is arranged, little cross bar should have in the 10-15cm from the scaffold termination;
4) slideway is installed
After scaffold building was good, the triangle frame body side surface was installed slideway;
Mould bases is set up:
The support body that utilization is set up is reinforced the template installation in place, has enough to meet the need the use of climbing repeatedly.
Support body of the present invention adopts channel-section steel to be welded on and forms the support body of encorbelmenting on the reinforced concrete column, both as the support system of the security maintenance while of operating as template; Template adopts on-the-spot assembly of mirror board to make the large form integral hoisting, successively climbs with work layer.Adopt the present invention's effect height of constructing.Easy and simple to handle, technology is simple, safety factor is high.Adopt independently the unit support body of encorbelmenting, support body is firm, safety, and it is lighter to conduct oneself with dignity, and bearing capacity is bigger.Common steel tube is set up whole stressed space truss structure, saved material; Template is utilized common mirror board to piece together and is made large overall template, has increased the number of turnover of template.
The specific embodiment
Work progress of the present invention:
