Description

A kind of unidirectional detachable split bolt
Technical field
The utility model is related to technical field of building construction, more particularly to a kind of unidirectional detachable split bolt.
Background technology
With continuing to develop for construction industry, during building template installation, split bolt is used for wall form It is fixed, but traditional building template typically uses monoblock type with split bolt, in concreting process, split bolt with Concrete bonding is together, it is impossible to extract, it is impossible to reuse;Scissors wall is a kind of conventional building structure, can undertake each Internal force caused by kind of load, and can effective control structure horizontal force, when in outside, shear wall and pillar levels are constructed, because right Draw bolt together with concrete bonding, be completely fixed, and the part that split bolt exposes wall must be cut off with cutting machine, Remainder is stayed in wall, and not only later stage cutting expends a large amount of manpower and materials but also influences the attractive in appearance, it is necessary to carry out two of wall Secondary processing, construction cost increase, duration increase causes the wasting of resources;Although existing split bolt is detachable, part compared with Many, handling procedure is cumbersome, and form of construction work labor intensity is high, low construction efficiency, in addition, the split bolt stayed in wall, because of length Phase storage is allowed to moist, corrosion occurs, to the pre-buried hidden danger of security of building.
Utility model content
For defect present in prior art or deficiency, the utility model innovatively proposes a kind of unidirectional detachable Split bolt, simple in construction, convenient disassembly, it is repeatable utilize, it is practical, pass through dismantling screw, it is easy to which surface of wall is repaiied It is multiple, the cost of secondary wall processing is reduced, the duration is reduced.
What the technical solution of the utility model was realized in:
A kind of unidirectional detachable split bolt, the split bolt includes the nut fixed piece and set being embedded in wall Cylinder, the nut fixed piece includes nut, screw rod, is installed with and the integrally formed reinforcing bar of nut, institute in the nut both sides Sleeve one end is stated provided with external screw thread, is connected with having female nut screw, the sleeve interior surface is provided with internal thread, described One end of screw rod is connected with having female telescopic screw, and the other end of the screw rod is provided with four ribs rotated for spanner Angle;The split bolt also includes the fastener and buckle nut that steel pipe, centre have manhole, the fastener The side relative with steel pipe is provided with the neck with inserting for steel pipe side, and the screw rod is from the center of buckle nut, fastener Pass through, and be rotated clockwise in sleeve.
It is preferred that, the quantity of the steel pipe is set to two, respectively positioned at the both sides up and down of screw rod, and the one of every steel pipe Side is respectively implanted in neck, and the quantity of the steel pipe is adapted with the quantity of neck.
It is preferred that, position has square through hole centered on described tetraquetrous one end is installed with locking member, the locking member Handle.
It is preferred that, the handle is knop.
It is preferred that, the sleeve is pvc pipe.
Compared with prior art, the beneficial effects of the utility model are:
The utility model discloses a kind of unidirectional detachable split bolt, can be connected to become with one side formwork an entirety from And fix one side formwork;Sleeve interior surface is provided with internal thread, and one end of screw rod is connected with having female telescopic screw, passed through Outside rotary screw, screw rod is dismantled counterclockwise, is not only easy to the reparation of surface of wall, strengthens the aesthetic property of wall, and drop The other expenditures, obvious economic such as the cost and labour cost, fee of material, rental charge of low secondary wall processing;Because that need not enter Row after-treatment, can greatly save the duration, save the energy, meet society's requirement economic to " low-carbon ", improve job site Integrated environment.
