Specific embodiment
The design of the utility model most critical is: the nut in anchor block card slot, which is screwed on reinforcing bar, using spanner is made
Reinforcing bar is obtained to be connected with sleeve.
For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation
Mode simultaneously cooperates attached drawing to be explained in detail.
Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of non-grouting set for the connection of prefabricated reinforced concrete pendant reinforcing bar
Tin, the first reinforcing bar and the second reinforcing bar with helicitic texture in need to connect, the sleeve setting are set between the pendant
The second opening for having first connect with first reinforcing bar to be open and connect with second reinforcing bar, the sleeve are interior described
First opening is connected to an anchor block, and hole and card slot are equipped at the anchor block center, has one to be only capable of in card slot at the card slot
Mobile nut；First reinforcing bar screws in the nut after passing through first opening, described hole.Pass through nut and anchor
Block, so that reinforcing bar is connected with connection sleeve, so that two reinforcing bars are connected, and whole process is not all needed to be perfused into sleeve and be mixed
Solidifying soil paste a, it is only necessary to spanner.The design of hole and card slot, by position of the adjusting nut on card slot, so that two
Two reinforcing bars that shaft core position is not exclusively overlapped can also connect.
Further, an inner and outer wall is arranged in the second opening in the sleeve has helicitic texture and screw thread side
To opposite cylinder, second reinforcing bar is connected by screwing in the cylinder with second opening.Anchor block and nut enter
Before in sleeve, need then to enter by second opening again outside sleeve first by the card slot of nut loading anchor block
In sleeve, so introducing a cylinder, while enabling sleeve to be completely embedded by cylinder and the second reinforcing bar, anchor convenient for loading and unloading
Block and nut.Further, since the diameter of second opening is greater than the diameter of the second reinforcing bar, convenient wrench is open from described second
Place enters sleeve inner and carries out turning operation to nut.
Further, the interior bore of first opening becomes larger from outside to inside, shaped like funnel；The anchor block outer wheels
Profile such as circular cone.It is combined with each other by circular cone and funnel shaped, anchor block can not leave sleeve from first opening, due to nut
It is connect with first reinforcing bar, i.e., so that first reinforcing bar and the sleeve connection.
Further, described hole is the cylindrical cavities that bottom surface is in oblong, and the card slot is in rectangle, first reinforcing bar
Eccentric in described hole it can move and the nut is driven to move in the card slot.Even if first reinforcing bar and the second steel
The central axes of muscle do not overlap, and no matter the central axes of two reinforcing bars with the deviation of which kind of direction, are designed using slotted hole so that the
The first reinforcing bar can deviate the central axes of anchor block when one reinforcing bar is connect with anchor block, if adjust offset anchor block central axes amplitude and
Direction guarantees that anchor block center line is overlapped with the central axes of second reinforcing bar, sleeve can be enable to be further advanced by the circle
Cylinder connects two reinforcing bars.The card slot of rectangle, so that nut can only be moved back and forth along card slot direction, without along any
It disorderly shakes in direction.
Further, the gasket for fixing first reinforcing bar is provided at described hole.Confirm nut on anchor block
Specific location after, gasket is filled in hole and fixes the first reinforcing bar, prevents position of the nut in card slot from moving.
Further, the anchor block with respect to the other end of one end of hole be additionally provided with two strips for preventing spiral shell
Mother falls off the protrusion of the card slot.Design outstanding, so that nut can not be detached from anchor block after nut and anchor block are packed into sleeve,
It is not between anchor block and nut due to the phenomenon that relative displacement occur and gasket is caused to fall off.
Further, first reinforcing bar and the second bar diameter are d, and described hole bottom surface oblong length is L, wide
Degree is W, wherein d+2mm≤L≤d+20mm, d+0.1mm≤W≤d+10mm.This size can guarantee requirement.
Further, oblong length in described hole bottom surface is L=d+10mm, width W=d+2mm.This size was both protected
Requirement is demonstrate,proved, and guarantees that anchor block has high mechanical strength.
Further, the sleeve is cylindrical.This tube-in-tube structure is simple, easy to process.
Further, the first open end flare of the sleeve, the second open end of the sleeve are cylindrical.This
The materials'use amount of sleeve is less relative to cylindrical sleeve.
In conclusion a kind of non-grouting set for the connection of prefabricated reinforced concrete pendant reinforcing bar provided by the utility model
Cylinder, by nut and anchor block, so that reinforcing bar is connected with connection sleeve, so that two reinforcing bars are connected, and whole process is all not required to
It to be starched concrete perfusion into sleeve, it is only necessary to a spanner.Even if the central axes of first reinforcing bar and the second reinforcing bar
It does not overlap, and no matter the central axes of two reinforcing bars with the deviation of which kind of direction, are designed using slotted hole so that the first reinforcing bar and anchor
The first reinforcing bar can deviate the central axes of anchor block when block connects, as long as adjusting amplitude and the direction of offset anchor block central axes, guarantee
Anchor block center line is overlapped with the central axes of second reinforcing bar, and sleeve can be enable to be further advanced by the cylinder for two reinforcing bars
It connects.Before anchor block and nut enter in sleeve, due to being provided with the protrusion for preventing nut from falling off on card slot, need covering
Nut is first packed into the card slot of anchor block by cylinder outside.It is funnel shaped first opening and cone anchor block be combined with each other, anchor block without
Method leaves sleeve from first opening, and needs to enter in sleeve by second opening.A cylinder is introduced, so that set
Cylinder by cylinder and the second reinforcing bar while can be completely embedded, anchor block and nut convenient for loading and unloading, and also convenient wrench is from described second
Opening enters sleeve inner and carries out turning operation to nut.After confirming specific location of the nut on anchor block, gasket is filled in
The first reinforcing bar is fixed in hole, prevents position of the nut in card slot from moving.And nut can only be along card slot direction
It moves back and forth, anchor block can not be detached from, that is, be not in cause gasket to fall off due to there is relative displacement between anchor block and nut
The phenomenon that.
Herein first, second ... only represents the differentiation of its title, not representing their significance level and position has what
It is different.
Herein, up, down, left, right, before and after only represents its relative position without indicating its absolute position
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
