Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
An implementation is illustrated a kind of use shape for the positioning tool of concrete-bar component in cushion cap to Fig. 2-3 according to the present invention
State schematic diagram.As Figure 2-3, cushion cap 4 has a bed course 40.Concrete-bar component 5 includes more reinforcing bars 50 and Steel bar rack 51.It is more
Root reinforcing bar 50 is all connected to Steel bar rack 51, to form an overall structure.Its rigidity is larger.Setting is spaced between more reinforcing bars 50
And it is parallel to each other.
Positioning tool 1 includes lower positioning device 2 and upper positioning device 3.Lower positioning device 2 be used for by more reinforcing bars 50 extremely
The bottom of few two reinforcing bars 50 is positioned at the predeterminated position of bed course 40, is existed with limiting the bottom of more reinforcing bars 50 relative to bed course 40
The side vertical with the short transverse 6 of cushion cap shifts up.
The bottom of at least two reinforcing bars 50 in more reinforcing bars 50 can be positioned at the bed course 40 of cushion cap 4 by lower positioning device 2
Predeterminated position, to limit displacement of the more reinforcing bars 50 relative to bed course 40 on the direction vertical with the short transverse 6 of cushion cap,
To ensure that concrete-bar component 5 more reinforcing bars 50 bottom relative to bed course 40 in the side vertical with the short transverse 6 of cushion cap
Upward positioning accuracy.
Upper positioning device 3 includes positioning plate 30 and multiple positioning regions 31.Positioning plate 30 has the more of spaced, parallel setting
A location hole 300.It is arranged in a one-to-one correspondence between multiple location holes 300, more reinforcing bars 50 and multiple positioning regions 31.Each reinforcing bar
50 top is through corresponding location hole 300.And positioning plate 30 is correspondingly arranged the regions of at least three reinforcing bars 50 and is respectively provided with
There is support portion 32.Support portion 32 hangs on the top of corresponding reinforcing bar 50.
Each positioning region 31 is inserted between corresponding location hole 300 and corresponding reinforcing bar 50, so that each

It is very little) it is identical.Each positioning region 31 is inserted between a corner of corresponding location hole 300 and corresponding reinforcing bar 50, with
It is fixed on the top of each reinforcing bar 50 between corresponding location hole 300 and positioning region 31.And the top of each reinforcing bar 50
The outside wall surface in portion is resisted against the adjacent both sides of location hole 300.In the present embodiment, it leans in location hole 300 with reinforcing bar 50
Adjacent both sides possessed by the corner of location hole 300 be inserted into of corner and positioning region 31 be located on the diagonal line of location hole 300.
Each positioning region 31 is respectively positioned on the rear portion on the right side of corresponding reinforcing bar 50.
Further, positioning region 31 is cone nail.The width of square hole is 3mm-5mm bigger than the diameter of reinforcing bar 50, due to reinforcing bar
50 still have larger activity space in square hole, and unified (such as whole right backs) in one direction squeezes into cone nail.In this implementation
In mode, cone nail is one end diameter 10mm, the rod iron of the 10cm long of other end diameter 25mm.It is followed closely by cone and squeezes 50 direction of reinforcing bar
The same direction is mobile and contacts with positioning plate 30, realizes the relative position of reinforcing bar 50 all in accuracy rating requirement.
In addition, reinforcing bar 50 has at least four, and at least four reinforcing bars 50 are arranged in polygonized structure.It is located therein four
Four reinforcing bars 50 in corner are hung with support portion 32 respectively.Support portion 32 is fixed on positioning plate 30.In the present embodiment, more
Reinforcing bar 50 is square structural arrangement.
Four reinforcing bars 50 for being located therein four corners are hung with support portion 32 respectively, and support portion 32 is fixed on positioning plate
30, enable positioning plate 30 reliablely and stablely to hang on reinforcing bar 50, and then can guarantee that positioning plate 30 is opposite with reinforcing bar 50
Positioning, to further ensure plane positioning precision between multiple reinforcing bars 50 and each reinforcing bar 50 relative to cushion cap 4
Verticality.
Each support portion 32 includes cover board 33, angle member 34 and reinforcing rib 35.Cover board 33 is covered on corresponding reinforcing bar 50
Top top.Cover board 33 is fixed on the top of angle member 34, and positioning plate 30 is fixed in the bottom end of angle member 34.Reinforcing rib 35
It is fixed between angle member 34 and positioning plate 30.
