Description
Technical field
This utility model belongs to architectural engineering construction technique field, and in particular to a kind of detachable reusable to drawing spiral shell
Bolt.
Background technology
In construction, split bolt is fixed for two side template of body of wall.It is existing to pour for armored concrete
Split bolt typically adopt monoblock type, in casting process, split bolt is together with concrete bonding, it is impossible to extract, no
Can reuse, and the two ends that split bolt exposes body of wall must be cut off with cutting machine, remaining section is stayed in body of wall, not only shadow
Ring body of wall attractive in appearance, and cause waste of resource；Although some split bolt two ends can be dismantled, part is more, and handling procedure is numerous
Trivial, these form of construction work labor intensity are high, and efficiency is low；Additionally, there is rust because contacting with water for a long time in the bolt stayed in body of wall
Erosion, the safety to building are impacted.
Utility model content
The purpose of this utility model is for the problems referred to above of the prior art, there is provided a kind of part is few, material-saving,
Detachable reuse split bolt easy to loading and unloading.
To realize above-mentioned utility model purpose, this utility model employs following technical scheme：
A kind of detachable reusable split bolt, including hollow sleeve, screw rod, fastener, locking member and two are anti-
The reserved packing ring of leakage；The hollow sleeve two ends have external screw thread, and pad is reserved with the leakproof for being engaged female thread respectively in two ends
Circle connection；Described screw rod one end is vertically fixedly connected with kelly, and the other end has external screw thread, is provided with fastener and locking above
Part；Centered on the locking member, position has the handle of through hole, and the female thread being engaged with the external screw thread of screw rod is provided with through hole；
Screw rod is passed through from hollow sleeve, the reserved packing ring of leakproof and handle centre.
Above-mentioned kelly center is welded with screw rod, and two ends have externally threaded one end bending to screw rod.
Above-mentioned hollow sleeve is pvc pipe.
Above-mentioned handle is knop.
Compared to prior art, advantage of the present utility model is：
This utility model is connected with kelly using one end, and the other end is provided with the screw rod of fastener and locking member, repeatable to make
With reducing the quantity of part, be more convenient for carrying and deposit；And the clasp and locking member of one end need to be only installed when dismounting,
Reduce 50% workload；Centered on locking member, position has the handle of through hole, is more convenient handling, improves work effect
Rate.
Description of the drawings
Fig. 1 is scheme of installation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the schematic diagram of handle described in the utility model.
In figure：1.PVC hollow sleeves, 2. leakproof reserve packing ring, 3. kelly, 4. fastener, 5. knop, 6. screw rod,
7. template, 8. steel pipe, 9. concrete wall.
Specific embodiment
With reference to embodiments and its accompanying drawing is further non-limitingly described in detail to technical solutions of the utility model.
First, the basic structure of the detachable reusable split bolt of the present embodiment
As shown in Figures 1 to 3, detachable reusable split bolt, including PVC hollow sleeves 1, screw rod 6, fastener 4,
Packing ring 2 is reserved in locking member and two leakproofs；1 two ends of PVC hollow sleeves have external screw thread, and two ends are engaged interior spiral shell with having respectively
The reserved packing ring 2 of the leakproof of stricture of vagina connects；6 one end of screw rod is vertically fixedly connected with kelly 3, and the other end has external screw thread, is provided with above
Fastener 4 and locking member；Centered on the locking member, position has the knop 5 of through hole, is provided with outer with screw rod 6 in through hole
The female thread that screw thread is engaged；Screw rod 6 is passed through from the reserved packing ring 2 of PVC hollow sleeves 1, leakproof and 5 center of knop.Kelly 3
Center is welded with screw rod 6, and two ends are bent to screw rod 6 with externally threaded one end.
2nd, the operation principle of the detachable reusable split bolt of the present embodiment
The length of PVC hollow sleeves 1=- 2 × leakproof of thickness of wall body+14～15mm of reserved gasket thickness.During use, first will
Template 7, steel pipe 8 carry out installation combination, and 3 cross section size of screw rod is offered where the screw rod 3 in template 7 is corresponding
Hole；The small end face of leakproof reserved packing ring 2 is tightened in into 1 two ends of PVC hollow sleeves, the large end face of the reserved packing ring 2 of leakproof abuts mould
Plate 7；Screw rod 3 sequentially passes through the template 7 on one side, the template 7 of PVC hollow sleeves 1, another side for putting the reserved packing ring 2 of leakproof, card
Fastener 4 and knop 5, by 3 clamping steel pipe 8 of kelly after, tighten knop 5 and template 7 fixed.Pour body of wall it is dry after,
Knop 5 is turned on, fastener 4 and screw rod 6 is taken out, then the reserved packing ring 2 of leakproof is dismantled from concrete wall 9, in case next
Use；PVC hollow sleeves 1 are stayed in body of wall.
It is pointed out that above-described embodiment is only to illustrate technology design of the present utility model and feature, its object is to
Allow person skilled in the art will appreciate that content of the present utility model and implement according to this, this practicality can not be limited with this new
The protection domain of type.All equivalence changes made according to this utility model spirit or modification, should all cover new in this practicality
Within the protection domain of type.
