In figure: outer impeller 1, insulation board 2, interior impeller 3, Cast-in-Situ Segment 4, template 5, pre-embedded steel slab 6, one sections of bars 7, taper PVC
Casing 8, nut 9, two sections of bars 10, fasteners 11.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing:
Split bolt provided by the utility model is cast-in-place for the progress wall installation of assembled sandwich heat preserving wall body Cast-in-Situ Segment
Section construction, for fixing Cast-in-Situ Segment template.The structure to be contacted of split bolt as shown in Figure 1, include outer impeller 1, insulation board 2,
The Cast-in-Situ Segment 4 and template 5 opposite with interior impeller 3.
As shown in Figure 1-3, pouring a section template reinforcing bolt after sandwich thermal insulation board precast facade provided by the utility model, it is used
In assembling type outer wall Cast-in-Situ Segment formwork reinforcement.The reinforcing bolt is two-period form composite structure, wherein one section of bar 7 is pre- in outer impeller
It is embedded in when processed in outer impeller, it is welded with pre-embedded steel slab 6 in outer impeller, and two sections of bars 10 are connected as with one section of bar 7 by nut 9
Integrally, template 5 being passed through on the outside of two sections of bars 10 and being exposed to 5 outside a part of template, exposed portion is locked by fastener 11.
The utility model is described in detail below by one embodiment:
The reinforcing bolt of two-period form composite structure, one section of bar 7 are that a diameter 14mm, end are formed with screw thread and are equipped with spiral shell
The rod piece of mother 9, one section of bar 7 is pre-buried preceding i.e. in nut 9.
Two sections of bars 10 are diameter 14mm, rod piece of the surface with screw thread.Screw thread can be made in two sections of bar overall surfaces.It can also be with
Only in end system a part for connecting with nut, then in the middle part of two sections of bars 10 need to fill position system a part of fastener 11.
Two sections of bar screw thread ends and pre-buried rod piece (i.e. one section of bar) nut thread are affixed.Specific structure is as shown in Fig. 2, one section of bar
7 screw thread is screwed on the left of nut 9, and the screw thread end of two sections of bars 10 is screwed on the right side of nut 5, and two bars dock in nut 9, is passed through
Two bars are combined as a whole by nut 9.Two sections of 10 other ends of bar pass through pattern hole, and screw rod is exposed to 5 outside 100mm of template, with button
Part 11 is locked.It is also possible to nut is screwed on one section of bar, by nut-welding in two sections of rod end heads, installation such as Fig. 4.
The length described in the utility model for reinforcing bolt is the length after one section of bar, 7, two sections of bars 10 dock, its length is
Siphonal lobe concrete cover+heat preservation plate thickness+outer wall thick+inner side template and the stupefied thickness+100mm of primary and secondary.As shown in Figure 1, one section of bar 7 is located completely
In 5 inside of Cast-in-Situ Segment template, two sections of bars 10 pass through template 5 and are threadedly coupled with one section of bar 7.That is the docking of one section of bar, 7, two sections of bars 10
It is in 5 inside of template.
In the utility model design, two sections of bars 10 are expected to remove after 4 concrete initial set of Cast-in-Situ Segment, therefore are
It avoids concrete from building nut 9, taper PVC casing 8 has also been devised outside the nut 9 of one section of bar 7, two sections of bars 10 docking.Knot
Closing is the straight pipe being adapted to nut diameter inside 3,4 taper PVC casing 8 of attached drawing, the taper sheath being integrated outside straight pipe, cone
Shape set can be by nut cover among inner cavity, 8 overall length 40mm of this taper PVC casing.
It when taper PVC casing is installed, is buckled on nut, and be close to template-setup, nut is retracted 2mm in taper.
When form removable, the fastener 11 in 5 outside of template is unscrewed, unloads two sections of bars 10, form removal 5 is unloaded with special spanner
