As preferably, the described otic placode that turns up is more than two.
As preferably, the described otic placode that turns up is positioned at steel plate both sides.
As preferably, described steel plate is Wavelike steel webplate.
As preferably, the described otic placode that turns up is provided with through hole.
As preferably, in described through hole, be installed with and run through reinforcing bar.
As preferably, in described remaining hole, be installed with remaining hole reinforcing bar.
As preferably, in described remaining hole, be installed with remaining hole reinforcing bar, run through reinforcing bar and remaining hole reinforcing bar arranged crosswise.
As preferably, the radius of described turn up otic placode and steel plate corner is thickness of slab 2-21 times.

The toponym that in above accompanying drawing, each number designation refers to is as follows: 1-concrete, 2-steel plate, 3-otic placode that turns up, 4-remaining hole reinforcing bar, 5-run through reinforcing bar, 21-remaining hole, 31-through hole wherein.
The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 4 and embodiment, the utility model is described in further detail:
Embodiment 1
Eversion type otic placode weldless connection key steel concrete combining structure, as shown in Figure 1, 2, comprise steel plate 2, otic placode 3 and concrete 1 turn up, the described otic placode 3 that turns up is by turning up and form after steel plate 2 part cuttings, on steel plate 2, leave otic placode and rout up the remaining hole 21 of rear formation, the otic placode 3 that turns up is more than two, and the otic placode 3 that turns up is cast in concrete.
The otic placode 3 that turns up is positioned at steel plate 1 both sides.The otic placode 3 that turns up is provided with through hole 31.In through hole 31, be installed with and run through reinforcing bar 5.In remaining hole 21, be installed with remaining hole reinforcing bar 4.
In remaining hole 21, be installed with remaining hole reinforcing bar 4, run through reinforcing bar 5 and remaining hole reinforcing bar 4 arranged crosswise.
The radius of otic placode and steel plate corner of turning up is thickness of slab 5 times.The otic placode that turns up is by turning up and form after steel plate 2 parts cuttings, the steel plate after cutting in the process of turning up, with former steel plate transition coupling part be circular arc, the radius of this partial arc is thickness of slab 5 times.By circular arc-shaped corner is set, can effectively reduce the stress concentration phenomenon at the position of turning up, with in conventional art by welding otic placode mode compare, structural strength is high, manufacture craft is simpler, saves welding material simultaneously.
One of the characteristic of otic placode of turning up is its part that belongs to steel plate self, compares with the mode of traditional welding otic placode, has saved otic placode material and welding material, has reduced welding procedure, has improved bonding strength and the stability of otic placode and steel plate.
As shown in Figure 3, the difference of the present embodiment and embodiment 1 is: the minimum angle of the place plane of the otic placode that turns up and steel plate place plane is 0 °-90 °.If calculated according to 180 ° of angles, the place plane of the otic placode that turns up and plane included angle, steel plate place optimum are 30 °-150 °.
The place plane of otic placode of turning up and the minimum angle of horizontal plane are 0 °-90 °.The turn up reverses direction of otic placode 3, except needs, wearing the part that runs through reinforcing bar 5 and remaining hole reinforcing bar 4 is regular distribution, all the other otic placodes 3 that turn up turn over the optional position that ear can be in steel plate Transducers Embedded in Concrete part, be oriented random arbitrarily towards.Randomly like this arrange arbitrarily, the otic placode 3 that is more conducive to turn up improves steel plate and concrete bonding strengths, and plays better shearing resistance effect.
The radius of otic placode and steel plate corner of turning up is thickness of slab 10 times.
As shown in Figure 4, the difference of the present embodiment and embodiment 1 is: steel plate 2 is Wavelike steel webplate.The radius of otic placode and steel plate corner of turning up is thickness of slab 18 times.Knuckle radius is too small, and steel plate is seriously injured, and knuckle radius is excessive, is not highly resistant to shearing or direct shearing concrete.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
