13 vertical axis of plate is external；The hole of otic placode 13 is corresponded to each other with inner thread steel pipe built-in fitting 12, and otic placode 13 passes through insertion hole
And be threaded into steel pipe embedded part 12 beam side standing screw 11 and precast beam 1 it is fixed, and then vertical supporting rod 7 is fixed on prefabricated
On beam 1.
In conjunction with shown in attached drawing 4, the size of ribbed concrete superimposed sheet 2 is 2 × 5m, depth of floor 80mm, plate upper surface
It is made into the concave-convex artificial rough surface for being not less than 4mm, after top bars binding, together with bean column node one-piece casting concrete.
A kind of overlapping board construction method based on above-mentioned precast splice type superimposed sheet suspension type support construction, using applying as follows
Work step is rapid:
Step 1: prefabricated concrete folding plate with ribbing 2: carrying out the prefabricated of superimposed sheet 2 with ribbing according to design requirement in factory；
Step 2: precast beam 1 is installed: after the precast concrete column 17 of 500 × 500mm of sectional dimension is installed, and connecting
After node strength reaches requirement, corner brace is fixed on 17 top of precast concrete column by pre embedded bolt 20, pre embedded bolt
20 length are 300mm, 21 200 × 200mm of sectional dimension of corner brace, are made by the steel plate of thickness 50mm, 21 length 500mm of corner brace,
It is uniformly arranged twice deep floor 22 along its length, after corner brace 21 is fixed on 17 side of precast concrete column, between two columns
Precast beam 1 is placed, and the bottom of precast beam 1 and corner brace 21 are fixed by screw rod；
Step 3: support unit assemble: according to construction loads determine support rail 6 and vertical supporting rod 7 installation site and
Size determines that supporting adjustable angle is 45 °, panel point spacing 0.5m, buckles 10 for 6 He of support rail by square disk first
Vertical supporting rod 7 is fixed, and bolt 33 is inserted into square disk and is buckled in 10, and strike tightly, and knighthead 9 passes through oblique buckle ear
Plate 14 is attached, and when knighthead 9 is installed, 6 bolt of support rail should not first be struck tightly, to single section triangle truss forming school
Tight reinforcing is struck after just again, and screws on bolt screw rod 36 in the threaded hole 35 of 33 bottom of bolt, 36 length of bolt screw rod is
20mm；
Step 4: support unit is hung: the support unit assembled in step 3 being fixed on precast beam 1, is used
Support unit is fixed to 1 two sides of precast beam by the mode of two o'clock lifting, the internal screw thread on screw hole and precast beam 1 on otic placode 13
12 position of steel pipe embedded part is supported frame using beam side standing screw 11 after being overlapped and fixes；
Step 5: support system forms: being attached each support unit by waling stripe 39 and horizontal cross bar 38
Fixed, the fixed one end of connection Shi Xianyong bolt 33, then the fixed other end, the bolt 33 at 38 both ends of horizontal cross bar should not first strike tightly,
System to be supported form completely correction after strike tight reinforcing again, finally bolt screw rod 36 is screwed into threaded hole 35, support system at
Type；
Step 6: support system precompressed: after support system is completed, plate body is laid on support system, by construction
Load and its distribution form carry out the symmetrical packed sand material of equal-load preloading to support system, and hierarchy node position adjustment to be supported is steady
It is unloaded after fixed, it is high that installation flitch 37 adjusts top mark；
Step 7: ribbed concrete superimposed sheet 2 lifts: using 4 points of liftings, drawing the alignment of ribbed concrete superimposed sheet 2
Fixed 2 position line of ribbed concrete superimposed sheet slowly it is stable fall it is preliminary in place after, with the shelving length at crowbar adjustment support,
Ribbed concrete superimposed sheet 2 is tightly combined with the flitch 37 on strutting system after ensuring to adjust；
Step 8: the perforation reinforcing bar 3 of ribbed concrete superimposed sheet 2 is constructed: after the lifting correction of ribbed concrete superimposed sheet 2,
The distribution bar of ribbed concrete superimposed sheet 2 protrudes into precast beam 1, and ribbed concrete superimposed sheet 2 protrudes into the length of 1 side form of precast beam
Degree is not less than 15mm, and binds negative reinforcement 15 on beam by drawing, and negative reinforcement 15 uses HRPB335 reinforcing bar on beam,
Perforation reinforcing bar 3 is laid with according to drawing requirement at rib of slab preformed hole 4；
Step 9: top bars are installed: 2 top bars 16 of ribbed concrete superimposed sheet bind according to construction drawing solid
Fixed, top bars 16 use second level reinforcing bar, floating when preventing offset and concreting；
Step 10: 2 piece of ribbed concrete superimposed sheet is handled: before wallboard and overlapping board concrete 5 pour, to ribbing
2 bottom piece of concrete folding plate and its gap between wallboard are checked, the overlapping of ribbed concrete superimposed sheet 2 is arranged
Plate cracking resistance muscle 29, the position excessive to some gaps carry out closure processing, paste foam adhesive tape, mortar leakage prevention；
Step 11: pouring overlapping board concrete 5: when pouring overlapping board concrete 5, with plate vibrator vibration compacting,
Combined with to guarantee it with ribbed concrete superimposed sheet 2 integral, while cloth is uniform, and cloth piling height strictly presses in-situ layer lotus
It carries and adds construction loads 1kN/m2Control, pouring layer height is 70mm；
Step 12: supporting removal: carrying out symmetrical truss support body when overlapping 5 intensity of board concrete and meeting design requirement
The dismounting of system, and remove the corner brace 21 of 1 bottom of precast beam.
Above-described embodiment is only used for illustrating technical concept of the invention, rather than the restriction to rights protection of the present invention,
It is all to be made a non-material change to the present invention using this design, protection scope of the present invention should all be fallen into.
