The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in fig. 1 to 5, a universal steel bar connection assembly for connecting a first target steel bar 5 and a second target steel bar 9 includes a first cylinder 2, a connecting rod 4 and a second cylinder 6, wherein one end of the connecting rod 4 is ball-hinged to the first cylinder 2, and the other end of the connecting rod 4 is ball-hinged to the second cylinder 6; a first connecting piece 1 used for being connected with a first target steel bar 5 is detachably installed in the first barrel 2, and a second connecting piece 8 used for being connected with a second target steel bar is detachably installed in the second barrel 6. So, first target reinforcing bar is connected with coupling assembling through first connecting piece, and the second target reinforcing bar passes through the second connecting piece and is connected with coupling assembling to realize 2 target reinforcing bar's being connected, because the connecting rod is articulated with corresponding barrel ball, even there is certain deviation (the central axis does not coincide) between first target reinforcing bar and the second target reinforcing bar, two target reinforcing bars also can be smoothly and normally be connected with coupling assembling, also can accomplish the connection of target reinforcing bar under fault-tolerant state promptly, adapt to actual construction scene better.
The barrel is provided with a first cavity A, a second cavity B, a third cavity C and a fourth cavity D which are sequentially distributed and communicated along the axial direction of the barrel, the cross sectional area of the first cavity A is gradually reduced from outside to inside along the axial direction to form a conical surface, and the cross sectional area of the second cavity B is gradually increased along the axial direction towards the direction far away from the first cavity A to form the conical surface. Preferably, each cavity is circular in cross-section throughout. In addition, the cylinder body of the type can be directly processed and obtained through a common numerical control machine, the manufacturing is convenient, and the cost is low.
One end of the connecting rod 4 penetrates through the first cavity of the first cylinder and extends into the third cavity of the first cylinder, the end of the connecting rod 4 is provided with a third connecting piece 3, and the side surface of the third connecting piece 3 close to the first cavity is a spherical surface, so that the connecting rod 4 can deviate from the central axis of the first cylinder; the other end of the connecting rod 4 penetrates through the first cavity of the second cylinder and extends into the third cavity of the second cylinder, a fourth connecting piece 7 is arranged at the end of the connecting rod 4, and the side face, close to the first cavity, of the fourth connecting piece 7 is a spherical surface, so that the connecting rod 4 can deviate from the central axis of the second cylinder.
The third connecting piece and the fourth connecting piece are both spherical nuts as shown in fig. 5. The third connecting piece and the fourth connecting piece can follow axial motion in corresponding third barrel, so, when having axial deviation between two target reinforcing bars, this universal reinforcing bar coupling assembling total length can change in certain extent, adapts to the deviation, realizes two target reinforcing bar's smooth and easy connections.
And two ends of the connecting rod 4 are respectively in threaded connection with the third connecting piece 3 and the fourth connecting piece 7.

In traditional cast-in-place construction, the mechanical connection mode of reinforcing steel bars is very common, but in the construction process of fabricated concrete, the original mechanical connection sleeve cannot be used (the deviation of the axes of the two reinforcing steel bars exceeds 0.1mm, and the threads cannot be screwed in). In the embodiment, the universal connection between two steel bars is realized by a two-pair spherical-conical surface connection (ball-cone connection for short) mode and a threaded connection mode, and the radial and axial allowable deviation between the two steel bars can reach 10-30 mm or more (of course, the manufacturing deviation of the prefabricated member steel bars is preferably controlled within 5mm generally).
Because of mechanical connection, the prefabricated concrete structure does not depend on specially-made high-strength grouting material, has smaller volume, higher reliability, convenient operation and wider application range, can greatly improve the prefabrication rate of the building and simultaneously reduces the comprehensive cost of the fabricated building. The utility model discloses a coupling assembling is relative the patent about reinforcing bar coupling assembling that applicant applied for before, and the structure is simple compacter.
When the connecting rod is used, the two ends of the connecting rod are inserted into the first barrel and the second barrel respectively, then the third connecting piece 3 and the fourth connecting piece 7 are installed at the two ends of the connecting rod respectively (in threaded connection), then connecting nuts are installed on the barrels (in threaded connection), and finally the connecting nuts are connected with corresponding target prefabricated part steel bars (in threaded connection). The barrel can freely rotate relative to the third connecting piece or the fourth connecting piece, and the barrel is rotated, so that the connection between the connecting nut and the target prefabricated part steel bar can be realized.
The above-mentioned embodiments are illustrative and should not be construed as limiting the scope of the invention, which is defined by the appended claims, and all modifications of the equivalent forms of the present invention which are obvious to those skilled in the art after reading the present invention.
