Description
Technical field：
This patent is related to the construction method of architectural engineering precast wall body Cast-in-Situ Segment.
Background technology：
In precast wall body cast-in-place section construction, split bolt hole is reserved generally in wall, then Cast-in-Situ Segment is tied up muscle,
Formwork, and reinforced with split bolt by hole to be provided, wait to beat ash, pour and reach the removable removing template in intensity rear.
On the basis of traditional cast-in-place concrete construction, precast facade cast-in-place section construction, with the form of construction work of cast-in-place engineering
It is similar, all it is utilized on wall and reserves split bolt hole, and Cast-in-Situ Segment is contained with template, finally use split bolt
Template is reinforced through reserving hole.
For prefabricated exterior wall, it is necessary to reserve split bolt hole on wall when making, reduce live peace
Secondary perforate during dress causes the destruction to wall, but needs to seal split bolt hole after wall installs
Stifled, because reserving hole is through siphonal lobe in wall, this, which results in wall, can not ensure the complete of its water proofing property.
The content of the invention
The present invention needs to reserve split bolt hole, shadow on wall siphonal lobe to solve the installation method of template in the prior art
The problem of ringing the water proofing property of siphonal lobe, this problem carries out bolt hole repairing in the later stage even if siphonal lobe can not also remedy.The present invention is guarantor
Demonstrate,prove the water proofing property of assembled wall siphonal lobe, there is provided a kind of Formwork Installation Method, its concrete technical scheme are：
A kind of prefabricated exterior wall Cast-in-Situ Segment internal lobe Formwork Installation Method, 1) again on prefabricated fixed structure inner surface
Installation sleeve, sleeve set internal thread；2) bolt hole is opened up in internal lobe template；3) bolt of internal lobe template is passed through with a threaded rod
Hole, inner termination are fixedly connected on sleeve, and external end head sets nut, tightening nut locking internal lobe template.
This method to internal lobe model sheetinstallat need not on siphonal lobe prepared screw-bolt hole, will not also be punched on siphonal lobe, no
Siphonal lobe wall is destroyed, ensures the entirety of siphonal lobe, ensures water proofing property performance.
When the width that siphonal lobe is more than internal lobe is less than 150, sleeve is fixed in the pre-buried steel ledges inner surface of internal lobe.Most bottom
The sleeve in portion is located at the position away from base 200mm；Sleeve vertical direction 500mm mono- is arranged.
When the width that siphonal lobe is more than internal lobe is more than 150, internal lobe scope is extended in the pre-buried heat-insulation layer connector of siphonal lobe
Termination screw thread, sleeve are fixedly mounted on heat-insulation layer connector termination.
When siphonal lobe be more than internal lobe width be more than 250 when, for the improvement under the second operating mode, sleeve and threaded rod longitudinal direction
Provided with two row.Every two row sleeve spacing 100mm.
The arrangement of sleeve is still that the sleeve of bottommost is located at the position away from base 200mm.Sleeve vertical direction 500mm mono-
It is individual to be arranged.

In figure：Internal lobe 1, siphonal lobe 2, internal lobe template 3, heat-insulation layer 4, pre-buried steel ledges 5, heat-insulation layer connector 6, sleeve 11,
Threaded rod 12, nut 13.
Embodiment
Internal lobe template 3 should be first installed before being poured to internal lobe 1 and carry out supporting.Before model sheetinstallat is carried out, first
Mounted is prefabricated wall siphonal lobe 2, and heat-insulation layer 4 is fixed on the inner side of siphonal lobe 2 with heat-insulation layer connector 6.Heat-insulation layer connector 6
Pedestal is just embedded in siphonal lobe 2 in prefabricated siphonal lobe 2, and the termination of heat-insulation layer connector 6 extends to the scope of internal lobe 1 through heat-insulation layer 4,
Before internal lobe 1 pours, prefabricated pre-buried steel ledges 5 in internal lobe 1.
The installation method purport of the present invention is the not drilling on siphonal lobe 2, protects the complete of siphonal lobe 2, ensures its water proofing property
Energy.Then the installing component of internal lobe template 3 is arranged in the more existing structure fixed, the table on the inside of existing structure
Face fixes sleeve 11, then bolt hole is opened up in internal lobe template 3, it is connected with a threaded rod 12 through internal lobe template 3 with sleeve 11,
Screwed again with nut 13 from outside and fix internal lobe template 3.
Siphonal lobe, which can be designed when prefabricated, goes out greatly internal lobe one fixed width, the assembling for different walls, it is wide go out length not phase
Together, this installation method is illustrated with siphonal lobe operating mode different from internal lobe below.
First, when siphonal lobe extends beyond the part of internal lobe and is less than 150mm：Welded in the pre-buried steel ledges 5 of precast wall body internal lobe 1
Sleeve 11, other fixed connection modes can also be used.Sleeve 11 sets internal thread, and bolt hole is opened up in internal lobe template 3, with a screw thread
Bar 12 is fixedly connected on sleeve 11 through internal lobe template 3, and other end installation nut 13, tightening nut 13 fixes internal lobe template 3.
The position of first sleeve 11 is located at the height away from base 200mm, and then mono- progress sleeve of the upward 500mm of vertical direction is consolidated
It is fixed.
What the 2nd, siphonal lobe extended beyond internal lobe is partially larger than 150mm when being less than 250mm：Go out internal lobe in the width of precast wall body siphonal lobe 2
During 1 part, pre-buried heat-insulation layer connector 6.The termination of heat-insulation layer connector 6 extends to the surface screw thread of the scope of internal lobe 1；Set
Cylinder 11 is arranged on the termination of heat-insulation layer connector 6.Bolt hole is opened up in internal lobe template 3, internal lobe mould is passed through with a threaded rod 12
Plate 3 is fixedly connected on sleeve 11, and other end installation nut 13, be tightened internal lobe template 3.The setting of heat-insulation layer connector 6
Position is the set location of subsequent sleeve 11, then sets first heat-insulation layer connector 6 in the height away from base 200mm, then
The upward 500mm of vertical direction mono- is arranged.
3rd, siphonal lobe extends beyond when being partially larger than 250mm of internal lobe：Precast wall body siphonal lobe 2 it is wide go out internal lobe 1 part it is pre-
Heat-insulation layer connector 6 is buried, heat-insulation layer connector 6 extends to the termination screw thread of the scope of internal lobe 1, and sleeve 11 is fixedly mounted on insulation
Layer connector 6 termination, opens up bolt hole in internal lobe template 3, sleeve is fixedly connected on through internal lobe template 3 with a threaded rod 12
On 11, other end installation nut 13, be tightened internal lobe template 3.Such a operating mode is excessive because outer leaf width goes out internal lobe part, can cloth
Put multiple row sleeve 11 to be used to fix internal lobe template, each column is between left and right away from for 100mm.
The installation method of internal lobe template provided by the invention to internal lobe model sheetinstallat need not on siphonal lobe prepared screw-bolt hole,
Also it will not be punched on siphonal lobe, not destroy siphonal lobe wall, ensure the entirety of siphonal lobe, ensure water proofing property performance.
