Description
Technical field
The utility model relates to a kind of connection jig, particularly a kind ofly connects the jig that is connected that pin-connected panel steel large form and back cord use.
Background technology
In building operations, traditional connection pin-connected panel steel large form is made up of jig bolt and gib with the jig that is connected that back cord is used, wherein the jig bolt is the right angle hook, and the jig bolt is put into to gib above gib, when pin-connected panel steel large form through after repeatedly turnover is used repeatedly, the nut of jig bolt has loosening, so the jig bolt that is very easy to cause to connect jig directly comes off the connecting hole from pin-connected panel steel large form back of the body rib (having found to truly have the phenomenon that drops in actual use), fall in the high-altitude then, this is abnormally dangerous, be easy to injure by a crashing object the staff of job site and the pedestrian who passes by on one's way, have very big potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of pin-connected panel steel large form slip-off preventing back cord jig, solve the technical problem that traditional connection jig comes off from pin-connected panel steel large form easily.
For achieving the above object, the utility model adopts following technical scheme: a kind of pin-connected panel steel large form slip-off preventing back cord jig, form by jig bolt and gib, wherein the jig bolt is made up of a screw rod and the nut that is threaded in this root screw rod top, described gib is for can contain the empty stomach shape of jig bolt, there are two back cord clamps the left and right sides of gib belly, the bottom surface of described gib belly has screw hole, there is grab the outer end of described back cord clamp, it is characterized in that: described grab for order laterally, vertical each curved twice crotch of ㄣ shape once; On the front sidewall of described gib belly positive lateral aperture is arranged, have the interface channel that is communicated with positive lateral aperture and screw hole on the front sidewall of gib belly and the bottom surface; The width of described interface channel is greater than the diameter of jig screw rod 1, and the diameter of screw hole is less than the diameter of nut, and the diameter of nut is less than the width of positive lateral aperture.
On the back side sidewall of described gib belly the dorsal part face is arranged.
The end face of described gib belly has nut bore.
The front sidewall of described positive lateral aperture top and the back side sidewall of dorsal part face top all are the boss that outwards protrude.
The width of described interface channel is less than the diameter of screw hole.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model has overcome traditional shortcoming that jig comes off easily that is connected, the grab of described screw rod connects curved twice, even so becoming flexible appears in nut, screw rod can not drop from pin-connected panel steel large form back of the body rib easily yet.While is according to the variation of screw rod shape, the structure of described gib has also been done corresponding variation, this variation can the company of making curved twice screw rod put in the gib abdomen from the positive side of gib, and no longer above gib, put into to the gib abdomen, the benefit of doing like this be can the company of making curved twice screw rod very easily carry on the back rib and be connected with gib and pin-connected panel steel large form, make things convenient for the integral installation that connects jig thus, saved the template assembly time.
The utility model is made simple, promptly become the utility model after only need being improved traditional connection jig a little, traditional like this jig still can be utilized, the consequence that causes a large amount of wastes of material so prevented traditional connection jig to be eliminated, for enterprise's joint money synergy, can guarantee construction safety again simultaneously.
