Abstract
The present invention provides a kind of cast-in-place region construction method of precast facade: 1) prefabricated assembled wall while the prefabricated split bolt hole on the corresponding siphonal lobe in cast-in-place region；The split bolt hole is according to prefabrication cast-in-place area size and the length of overhanging siphonal lobe, by calculating true aperture and spacing；2) after wall being mounted on rigging position, the fixation that suitable split bolt carries out two side templates is installed in the split bolt hole of siphonal lobe；3) concreting of Cast-in-Situ Segment is carried out；4) after concrete initial set, withdraw from split bolt, and split bolt hole is blocked, this construction method no longer needs live punching, flying dust is avoided to influence construction environment, execute-in-place is avoided to cause component damage, the method fundamentally solves the trouble of construction in later period, substantially increases the efficiency of construction.
Description
Technical field
The invention belongs to prefabricated shear wall construction technical fields, and in particular to fabricated shear wall cast-in-place section construction
Method.
Background technique
Assembled architecture is now very widely used, and precast facade is wherein than a kind of more typical new technique.But
Wherein still have and much needs to have cast-in-place region, the outside in cast-in-place region among perfect place, such as two panels precast facade
It is the siphonal lobe wallboard that two panels precast facade cantilevers out, is needed after precast facade installs in cast-in-place region casting concrete,
But overhanging siphonal lobe wallboard is insufficient for acting as template, needs the formwork on the outside of siphonal lobe wallboard or punches installation pair in siphonal lobe wallboard
Bolt is drawn to fix with cast-in-place area inside template, this two methods operates more troublesome, it needs to take considerable time, and such as
Fruit takes no action to direct casting concrete, and precast wall body siphonal lobe can cause to rupture because of intensity deficiency in casting concrete,
Siphonal lobe is destroyed influence construction, and many troubles can be caused to construction.
Summary of the invention
It is outer the technical problem to be solved by the present invention is to often result in overhanging when the precast wall body cast-in-place section construction of the prior art
The impaired problem of leaf.
Goal of the invention of the invention is to provide a kind of easy construction, guarantees that siphonal lobe is intact, does not damage the outer foliar spray of precast wall body
Work method, the technical solution adopted by the present invention specifically:
A kind of cast-in-place region construction method of precast facade:
1) prefabricated assembled wall while the prefabricated split bolt hole on the corresponding siphonal lobe in cast-in-place region.The split bolt
Hole is according to prefabrication cast-in-place area size and the length of overhanging siphonal lobe, by calculating true aperture and spacing.
2) after wall being mounted on rigging position, suitable split bolt is installed in the split bolt hole of siphonal lobe and carries out two
Side template is fixed.
3) concreting of Cast-in-Situ Segment is carried out.
4) after concrete initial set, split bolt is withdrawn from, and split bolt hole is blocked.
This construction method no longer needs live punching, avoids flying dust from influencing construction environment, execute-in-place is avoided to cause component
It destroys, the method fundamentally solves the trouble of construction in later period, substantially increases the efficiency of construction.
Specific embodiment
The present invention is applied to the cast-in-place region among two panels precast facade, it is therefore an objective to siphonal lobe damage is protected, for construction
Convenience is provided.
The specific technical proposal of the invention is:
A kind of cast-in-place region construction method of precast facade:
1) prefabricated assembled wall while the prefabricated split bolt hole on the corresponding siphonal lobe in cast-in-place region.The split bolt
Hole is according to prefabrication cast-in-place area size and the length of overhanging siphonal lobe, by calculating true aperture and spacing.
2) after wall being mounted on rigging position, suitable split bolt is installed in the split bolt hole of siphonal lobe and carries out two
The fixation of side template.
3) concreting of Cast-in-Situ Segment is carried out.
4) after concrete initial set, split bolt is withdrawn from, and split bolt hole is blocked.
The prefabricated split bolt hole in the cast-in-place region of precast facade of the invention is complete together when wall is prefabricated in factory.
After grasping practical prefabrication size and overhanging the length of siphonal lobe, by prefabricated split bolt diameter is calculated, then determining pair
Draw bolt hole aperture, spacing.Guarantee that prefabricated bolt hole hole point position is accurate.
This construction method no longer needs live punching, avoids flying dust from influencing construction environment, execute-in-place is avoided to cause component
It destroys, the method fundamentally solves the trouble of construction in later period, substantially increases the efficiency of construction.
