Technical field
The invention belongs to architectural furniture field, and in particular to a kind of device that reinforcing bar is properly inserted to plain concrete pile
And construction method.
Background technology
At present, indivedual plain concrete piles have the situation of a small amount of reinforcing bar of interpolation in design, and existing common insertion method is
Carry out machinery strike after reinforcing bar is inserted to sink, such a method can not accurately ensure reinforcing bar after insertion pile body, and reinforcing bar is protected all the time
Hold vertical, and will not occur bending or fracture.
Although being related to the aid of reinforcing bar inserting at present, such as：A kind of reinforcing bar is disclosed in the U of CN 204081515
Intensive beam column concrete construction special auxiliary device, the servicing unit of such a slotting reinforcing bar, or traditional hammer mode is used, this
During insertion, reinforcing bar easily bends or is broken sample, it is impossible to ensure its quality；
Again for example：A kind of cast-in-place concrete pile moulding process of implanted reinforced bar cage is disclosed in CN17730224A, it discloses insert
Enter the mode of steel reinforcement cage, but it uses and first drilled, then hammering lifting, the mode of insertion, such construction technology mistake
Journey is comparatively laborious, and the duration is long.
Accordingly, it would be desirable to a kind of device that reinforcing bar is properly inserted to plain concrete pile is designed, and then it is mixed to solve reinforcing bar insertion element
The problem of solidifying soil constructional difficulties.
The content of the invention
The present invention provides a kind of device and construction method that reinforcing bar is properly inserted to plain concrete pile, using this device in element
Before concrete-pile perfusion initial set, to inserting a small amount of reinforcing bar in pile body, and ensure that reinforcing bar is vertical, the accurate linkage for entering pile body is filled
Put.
In order to solve the above-mentioned technical problem, the present invention proposes following technical scheme：Reinforcing bar is properly inserted plain coagulation by one kind
The device of native stake, it includes reinforcing bar body, and the termination of the reinforcing bar body is connected with straight screw sleeve by screw thread, described
The outer cover of straight screw sleeve and reinforcing bar body is equipped with steel pipe, and the top of the steel pipe and the contact position of reinforcing bar body pass through ten
Word iron is welded and fixed, and the outer cover of the steel pipe is equipped with gear, and the top of the steel pipe is connected with piling head.
The gear is meshed transmission with first gear and second gear simultaneously, first gear and the second gear difference
It is inserted into installed in another two on the steel pipe of reinforcing bar body exterior, forms gear-linked system, drives steel pipe to rotate together.
The reinforcing bar body includes reinforcing bar, and the bottom of the reinforcing bar is machined with external screw thread, is processed in the head end of reinforcing bar
There is tip.
The external screw thread of the straight screw sleeve and reinforcing bar constitutes the connection that is screwed.
