Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of precast beam reinforced bar construction technology.
The present invention is for achieving the above object, it is achieved through the following technical solutions: precast beam reinforced bar construction technology, first presses figure paper size dispensing, fixed personnel debug numerical-control bending center, Quality Inspector checks and accepts first semi-finished product rebar sizes made, and meets the requirements and carries out large batch of production; Muscle main at the bottom of Horse hoof is placed on pedestal, fixing web model support, according to beam slab Change of types, accurate settingout diaphragm framework of steel reinforcement position on web reinforcement model support; Colligation T web reinforcing bar, mould bases put in order by stirrup, is first fixed bottom stirrup; Secondly colligation horizontal bar, removes model support and is encrypted.
For realizing the purpose of the present invention further, can also be by the following technical solutions: in the construction of T beam roof steel bar, construct from lower to upper, first colligation hogging moment tooth plate position reinforcing bar on model support, place the wet seam pre-buried steel hoop location angle steel on model support of top board, ensure linearly straight, finally wear hogging moment corrugated tube and position. By lifting shoulder-pole hoisting T beam roof steel bar, the comb plate groove in template matches with the groove scale on fetal membrane, and when T beam forms makes, the position of perpendicular rib I-steel, is arranged on beyond top board embedded bar, it is ensured that do not have interference during roof steel bar integral hoisting; When roof steel bar integral hoisting is for ensureing lifting, reinforcing bar will not deform, and triangle shoulder pole hook spacing is 90cm and configuration pulley, it is ensured that reinforcing bar will not run-off the straight.
It is an advantage of the current invention that: in the present invention; adopt fetal membrane equalization; ensure that cover to reinforcement qualification rate; detect through cover to reinforcement instrument; beam slab average qualification rate is 95% additionally also assures that T beam stirrup, horizontal bar spacing are uniform; position is accurate, also can be accurately positioned the position of bellow, make T beam steel cage overall linear straight, attractive in appearance. This engineering method is easy to construction organization, can make T web reinforcing bar binding and roof steel bar colligation synchronous construction, forms the operation of flowing water face, additionally also facilitates the colligation of hogging moment tooth plate position reinforcing bar, improve efficiency of construction. Adopt this engineering method to make T beam steel, contribute to realizing the parallel operations of form fixer and bar bender, be conducive to the expansion of work surface, save cost.

Detailed description of the invention
Precast beam reinforced bar construction technology, first presses figure paper size dispensing, fixed personnel debugs numerical-control bending center, and Quality Inspector checks and accepts first semi-finished product rebar sizes made, and meets the requirements and carries out large batch of production; Muscle main at the bottom of Horse hoof is placed on pedestal, fixing web model support, according to beam slab Change of types, accurate settingout diaphragm framework of steel reinforcement position on web reinforcement model support; Colligation T web reinforcing bar, mould bases put in order by stirrup, is first fixed bottom stirrup; Secondly colligation horizontal bar, removes model support and is encrypted.
In the construction of T beam roof steel bar, construct from lower to upper, first colligation hogging moment tooth plate position reinforcing bar on model support, place the wet seam pre-buried steel hoop location angle steel on model support of top board, it is ensured that linearly straight, finally wear hogging moment corrugated tube and position.
By lifting shoulder-pole hoisting T beam roof steel bar, the comb plate groove in template matches with the groove scale on fetal membrane, and when T beam forms makes, the position of perpendicular rib I-steel, is arranged on beyond top board embedded bar, it is ensured that do not have interference during roof steel bar integral hoisting; When roof steel bar integral hoisting is for ensureing lifting, reinforcing bar will not deform, and triangle shoulder pole hook spacing is 90cm and configuration pulley, it is ensured that reinforcing bar will not run-off the straight.
At present in Precast T-Beam reinforcement construction, it is common to there is cover to reinforcement low qualified, bar spacing unshapeliness, the problems such as embedded bar line style is not straight. T beam steel fetal membrane process technology, it is possible to solve problems well. This technology application practice by Practical Project, achieves good effect, is embodied in:
1, steady quality
T beam steel adopts fetal membrane equalization; ensure that cover to reinforcement qualification rate; detect through cover to reinforcement instrument; beam slab average qualification rate is 95% additionally also assures that T beam stirrup, horizontal bar spacing are uniform; position is accurate; also can be accurately positioned the position of bellow, be that T beam steel cage overall linear is straight, attractive in appearance.
2, efficiency of construction is high
This engineering method is easy to construction organization, can make T web reinforcing bar binding and roof steel bar colligation synchronous construction, forms the operation of flowing water face, additionally also facilitates the colligation of hogging moment tooth plate position reinforcing bar, improve efficiency of construction.
