Description
Technical field
The present invention relates to a kind of connection jig, particularly a kind ofly connect 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 puts 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 connecting jig directly comes off (having found to truly have the phenomenon that drops in actual use) the connecting hole from pin-connected panel steel large form back of the body rib, fall in the high-altitude then, and 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.
Summary of the invention
The purpose of this invention is to provide 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 realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of pin-connected panel steel large form slip-off preventing back cord jig; Be made up of 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, and gib comprises barrel-shaped gib main body and two back cord clamps that are positioned at the gib main body left and right sides; On the bottom surface of said gib main body screw hole is arranged; There is downward grab the outer end of said back cord clamp, it is characterized in that: the bottom of said screw rod bends out horizontal bent rod, and laterally bent rod bends out vertical bent rod again downwards; On the front sidewall of said gib main body positive lateral aperture is arranged, on the back side sidewall of gib main body the dorsal part face is arranged, have the interface channel that is communicated with positive lateral aperture and screw hole on the front sidewall of gib main body and the bottom surface; The width of said interface channel is greater than the diameter of jig screw rod, 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 said gib main body the dorsal part face is arranged.
Said gib main body is up big and down small Square barrel shape.
The front sidewall of said positive lateral aperture top and the back side sidewall of dorsal part face top all are the boss that outwards protrude.
The width of said interface channel is less than the diameter of screw hole.
The front sidewall of said positive lateral aperture top and the back side sidewall of dorsal part face top all are the boss that outwards protrude.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention has overcome traditional shortcoming that jig comes off easily that is connected; The bottom of said 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.Simultaneously according to the screw rod shape variation; The structure of said gib has also been done corresponding variation; This variation can the company of making curved twice screw rod put in the gib from the front of gib, and no longer above gib, put into to gib, the benefit of doing like this be can companys 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, practiced thrift the template assembly time.
The present invention makes simply; Promptly become the present invention after only need improving 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.
