Description
Technical field
The present invention relates to one kind to reduce construction site recruitment, improve construction operating efficiency, reduce manually into
For the purpose of this.The mechanical field for its jointing structure being carried out to prefabricated (such as armored concrete) component connection reinforcing bar
Design and improvement.So as to design a kind of double eccentric block jointings of prefabricated components connection reinforcing bar.
Background technology
The rural migrant worker to be worked with going down town is reduced year by year, and live recruitment cost rises year by year；It is entirely cast-in-place by armored concrete
Construction technology is transferred to the inexorable trend that complete (or part) the fabricated construction technique of prefabricated components is construction industry development.Prefabricated components exist
In the manufacturing process it is difficult to ensure that position of connection reinforcing bar it is accurate, after prefabricated part hanging be it is not rotatable or mobile,
The position deviation for adjusting connection reinforcing bar again is impossible, and therefore, the jointing technology of prefabricated components is to realize that assembled is applied
The key technology of work technique, using foreign countries (such as armored concrete) prefabricated components jointing technology-as sleeve add grouting connect
Joint technique is connect, its grouting material is expensive and is influenceed by construction weather conditions (such as winter, rainy day), and joint space-consuming is big,
Time is grown, and its work progress is hidden in addition, and construction quality is not easy to check and control etc. and limits；Welding point technology is and for example used,
Its high energy consumption and by construction weather conditions (such as wind, rainy day) influenceed, joint space-consuming is big, the time length, in addition its weld
Position is hidden, and operation inconvenience, quality is not easy to check and control etc. and limits.
The content of the invention
The invention discloses a kind of prefabricated components connection reinforcing bar double eccentric block jointings, its by：Prefabricated components X steel
Muscle connecting filament discount (1), prefabricated components Y bar connecting screw thread head (2), inside and outside screw thread eccentric block (3), double internal threads buckle partially the heart
Block (4), branch sleeve (5), fastening bolt (6) are formed；(as shown in figure 1, accompanying drawing page 1/3).
It is characterized in that：Before prefabricated part hanging, by inside and outside screw thread eccentric block (3) and double internal thread button eccentric blocks (4) and even
Female connector cylinder (5), fastening bolt (6) are separately mounted to prefabricated components X bar connecting screw thread head (1) and prefabricated components Y reinforcing bar
On connecting filament discount (2) (as shown in Fig. 2-1 and Fig. 2-2 in Fig. 2, accompanying drawing page 2/3)；, will be inside and outside after prefabricated part hanging
Screw thread eccentric block (3) and double internal thread button eccentric block (4)) each rotate against and make both close to adjust axial location deviation, when
Two eccentric blocks ((3) and (4)) further rotate during close makes both cylinder axis overlap to adjust radial direction position
Deviation is put, then the screw thread of branch sleeve (5) is screwed into the male thread of inside and outside screw thread eccentric block (3), connection both ((3), (4)),
Finally tighten fastening bolt (6) and hold out against two eccentric blocks ((3) and (4)) to fix axial location, member X and member Y is existed
In the state of keeping former installation site constant, member X and the radial and axial position deviation of member Y bar connecting screw thread head are eliminated
By its bar connecting together, (as shown in Fig. 3-1 and Fig. 3-2 in Fig. 3, accompanying drawing page 3/3).
