Description
Technical field
It the utility model is related to building anchoring field, more particularly to crab-bolt.
Background technology
With the development of countries in the world expressway construction, the complicated landform such as subway tunnel, plateau mountain region builds highway
Demand increases year by year, and tunnel and slope retaining are using quite varied.Implement a scientific outlook on development, realize that railway, highway are sustainable
Development, also it is exactly new industrialization to be walked, industrialized development road is realized by technological innovation.
Pre-buried lifting crab-bolt, lifting during for the concrete prefabricated demoulding in lifting, transport and installation process.It is first during use
Two-sided pre-buried lifting crab-bolt and counterpart are nuzzled in concrete in advance, working of plastics is broken after concrete curing into pieces and can be achieved to lift,
Complete lifting.Prior art needs to assemble, and preparation is time-consuming big, and efficiency is low.It is dumb to lift by crane angle.Some products need
Independent supporting lifting tool, cost are high.
Utility model content
To solve the above problems, providing a kind of new pre-buried lifting crab-bolt, it may be mounted at column or similar
It is used for lifting by crane on concrete product；The technical scheme provided is as follows：A kind of new pre-buried lifting crab-bolt, it is characterised in that bag
Include crab-bolt body and be sleeved on the stripper of crab-bolt body end, crab-bolt body is reversed into the two parts being not parallel to each other, the demoulding
Device, which includes, is provided with openable sealing baffle at hemispherical crab-bolt cover and crab-bolt cover opening, crab-bolt body end is additionally provided with
Link up with and hook is arranged in crab-bolt cover.
On the basis of above-mentioned technical proposal, crab-bolt body is reversed into orthogonal two parts.
On the basis of above-mentioned technical proposal, crab-bolt cover inwall is provided with screw thread and thread plate is arranged in crab-bolt cover,
Crab-bolt cover outer rim outward opening extends and exceedes thread plate, and sealing lattice gear is arranged on the outer rim opening of crab-bolt cover.
On the basis of above-mentioned technical proposal, the through hole passed through for reinforcing bar is offered on crab-bolt body.
Handle is additionally provided with the basis of above-mentioned technical proposal, on thread plate.
Beneficial effect：It may be mounted on column or similar concrete product and be used for lifting by crane.While torsion structure
Crab-bolt has higher intensity, while has two seals protection so that hook will not be flooded by concrete.

Embodiment
A kind of new pre-buried lifting crab-bolt as shown in drawings, it is characterised in that include crab-bolt body 1 and be sleeved on anchor
The stripper of the end of bolt body 1, crab-bolt body 1 are reversed into the two parts being not parallel to each other, and stripper includes hemispherical crab-bolt cover 2
And the opening of crab-bolt cover 2 is provided with openable sealing baffle 6, the end of crab-bolt body 1 is additionally provided with hook 4 and hook 4 is set
In crab-bolt cover 2.
A kind of crab-bolt in concrete is present embodiments provided, the end set of crab-bolt body 1 has flare shape
Stripper, stripper cover the hook 4 for being similarly disposed at the end of crab-bolt body 1, and stripper includes crab-bolt cover 2 and is arranged on
The sealing baffle 6 that crab-bolt cover 2 is open.Crab-bolt body 1 is crab-bolt body 1 by a plane in distortion or torsion shape
The shape that overall twisting is not parallel to each other in both ends, so sets the intensity that can improve crab-bolt body 1.When in use, by crab-bolt
Body 1 and stripper are positioned over together in mould and penetration concrete floods crab-bolt body 1, and stripper is hugged in coagulation
The opening of crab-bolt cover 2 of either stripper flushes with concrete outside soil, after treating concrete setting, uses sharp thing
Body punctures sealing baffle 6, the suspension hook of crane gear is hung on the hook 4 of the end of crab-bolt body 1, can be sling.It is worth note
Meaning, stripper can be arranged on both ends i.e. two of crab-bolt body or be only arranged at crab-bolt body 1 wherein
One end, same hook 4 be also in this way, but the position that has hook 4 necessarily there is stripper to be covered, and by the position of stripper
Hook 4 can be not provided with.
Preferably, crab-bolt body 1 is reversed into orthogonal two parts.It is preferred that the windup-degree of crab-bolt body 1 is limited
For 90 degree, i.e., two parts that crab-bolt body 1 mutually twists are vertically disposed.
Preferably, the inwall of crab-bolt cover 2 is provided with screw thread and thread plate 5 is arranged in crab-bolt cover 2, and the outer rim of crab-bolt cover 2 is opened
Mouth stretches out and exceedes thread plate 5, and sealing baffle 6 is arranged on the outer rim opening of crab-bolt cover 2.In order to more preferable screw thread
Cover plate 5 is connected by the screw thread in crab-bolt cover 2 with crab-bolt cover 2；And the outer rim outward opening of crab-bolt cover 2 extends and did not had or exceeded
The position of thread plate 5, sealing baffle 6 are arranged on the position of the outer rim opening of crab-bolt cover 2.Sealing baffle 6 can be punctured when in use,
Being rotated further by thread plate 5 can be drawn off.
Preferably, the through hole 3 passed through for reinforcing bar is offered on crab-bolt body 1.Further to improve crab-bolt body 1 in coagulation
Intensity in soil, while facilitate the arrangement of reinforcing bar, the through hole 3 for allowing reinforcing bar to pass through crab-bolt body 1 is provided with crab-bolt body 1.It is excellent
Choosing is additionally provided with handle 7 on thread plate 5.It is more laborsaving that thread plate 5 is rotated with handle 7.
