Description
Technical field
The utility model relates to a kind of construction tools more particularly to a kind of Urban Underground pipe gallery built-in groove to correct
Spanner.
Background technique
Urban Underground is constructed piping lane construction site, is led before wall pours, need to be installed to built-in groove in concrete floor, bottom plate
Position.After side wall and roof steel bar binding complete molding, because of the offset of adjustment protective layer and reinforcing bar, built-in groove is caused to become
Shape, offset, need to reexamine pre-buried groove location and timely correction position.Traditionally, it is such as sent out after side wall and top plate molding
Existing pre-buried groove location shifts, and because of operation faciostenosis, can only re-start amendment to built-in groove for after form removable.This is passed
Way of uniting seriously affects template construction because of complex procedures, and is still may cause after molding again because template squeezes built-in groove hair
Change shape, offset.
Utility model content
In view of the deficiency of the prior art, it is simple to provide a kind of structure for the utility model, structure is simple, operation side
Just, construction efficiency is improved, the built-in groove amendment spanner of construction cost is reduced.
Technical solution adopted in the utility model is:
A kind of built-in groove amendment spanner, including mobile jib, the rear end of mobile jib are provided with handlebar stem, the axis and mobile jib of handlebar stem
Axis perpendicular；The front end of mobile jib is provided with claw；The claw includes left side claw and right side claw；The left side claw and
Right side claw is separately positioned on the two sides of mobile jib；Left side claw and right side claw are symmetrical set along the axis of mobile jib；Left side
The axis of claw and right side claw is parallel with mobile jib axis；The left side claw and right side claw are fixedly connected with mobile jib；Institute
It states left side claw, right side claw and mobile jib end and constitutes rectangle card slot.
The left side claw right lateral surface, the left-hand face of right side claw are respectively arranged with arc-shaped fixing groove；Setting exists
Arc-shaped fixing groove on the claw of left side is corresponding with the arc-shaped fixing groove being arranged on the claw of right side.
A kind of built-in groove amendment spanner,
Including mobile jib, the rear end of mobile jib is provided with handlebar stem, the axis and mobile jib axis perpendicular of handlebar stem；Before mobile jib
End is provided with U-shaped fork；The front end of mobile jib is connected with the top that U-shaped is pitched；
U-shaped fork inner surface is provided with arc-shaped fixing groove, and arc-shaped fixing groove is symmetrical set.
The top of the U-shaped fork is provided with connection sleeve；The front end of mobile jib is arranged in sleeve, and sleeve has been disposed radially
Fixation hole；The front end of mobile jib has been disposed radially connecting hole；The front end of mobile jib is connected with sleeve by fastening bolt.
The utility model compared with the prior art the utility model has the advantages that
The utility model built-in groove corrects spanner, and structure is simple, easy to operate, improves construction efficiency, reduces construction cost,
Reduce labor intensity of workers.
After the completion of underground pipe gallery side wall and roof plate template mold, because template is squeezed caused by adjusting protective layer in the process
Pressure is kept away, reinforcing bar offset leads to the deformation of built-in groove, is not bonded with template, avoids traditional built-in groove amendment from needing using the utility model
Demoulding, the again cumbersome construction technology such as welding, while save the cost, ensure that built-in groove is precisely controlled and pours completion
Apparent mass afterwards.

Specific embodiment
Referring to the drawings and the utility model is described in detail in embodiment:
Attached drawing 1-4 is it is found that a kind of built-in groove corrects spanner, including mobile jib 11, the rear end of mobile jib 11 are provided with handlebar stem 12,
The axis and 11 axis perpendicular of mobile jib of handlebar stem 12；The front end of mobile jib 11 is provided with claw；The claw includes left side claw
13 and right side claw 14；The left side claw 13 and right side claw 14 are separately positioned on the two sides of mobile jib 11；13 He of left side claw
Right side claw 14 is symmetrical set along the axis of mobile jib 11；The axis of left side claw and right side claw is equal with mobile jib axis
Row；The left side claw and right side claw are fixedly connected with mobile jib；The left side claw, right side claw and mobile jib end constitute square
Shape card slot 15.
The left side claw right lateral surface, the left-hand face of right side claw are respectively arranged with arc-shaped fixing groove 16；Setting
Arc-shaped fixing groove on the claw of left side is corresponding with the arc-shaped fixing groove being arranged on the claw of right side.
A kind of built-in groove amendment spanner,
Including mobile jib 21, the rear end of mobile jib 21 is provided with handlebar stem 22, and axis and 21 axis of mobile jib of handlebar stem 22 mutually hang down

The utility model built-in groove corrects spanner, and structure is simple, easy to operate, improves construction efficiency, reduces construction cost,
Reduce labor intensity of workers.
After the completion of underground pipe gallery side wall and roof plate template mold, for caused by during adjustment protective layer because of mould
The problem of plate extruding is kept away, reinforcing bar offset leads to the deformation of built-in groove, is not bonded with template avoids traditional built-in groove amendment that from need to tearing open
Mould, the again cumbersome construction technology such as welding, while save the cost, after the completion of ensure that being precisely controlled and pour of built-in groove
Apparent mass.
Embodiment 1, with the round steel of diameter a 16mm, long 1500mm as mobile jib, the round steel of two root long 300mm of end
The groove shapes that mobile jib two sides form a 150mm long are welded on, the steel pipe that diameter a 20mm, long 150mm are welded in tail portion is made
For handle.Steel pipe handle is fully welded welding using two-sided with mobile jib junction, uses and is welded to connect at groove turning point.Construction
When, by groove from top insertion built-in groove, both hands have held handle, and the correction of built-in groove is carried out by can be manually rotated handle, being entangled
Partially.
Easy to use, easy to operate, the raising construction efficiency of the utility model.Compared with previous construction, after built-in groove
Correction time phase greatly shortens.Construction cost is reduced, avoids correcting pre-buried groove location in narrow work surface being that amendment is pre-buried
Slot dismantles template repeatedly.It is easy to carry, it after molding check at any time, corrects at any time, component is less, convenient for field fabrication.
The above descriptions are merely preferred embodiments of the present invention, not makees to the structure of the utility model any
