The enabling capabilities set.
Preferably, the top plate and support plate are hollow structure, alleviator own wt, while saving material.
Preferably, described pair of drawing nut is double nuts structure, double nuts structure can prevent nut from loosening, thus
Prestressing force is avoided to adjust situation not in place.
Preferably, the screw rod quantity is two, the front and rear sides of the support plate are symmetricly set on, can effectively be prevented
The case where only single screw rod is broken, improves safety.
Preferably, the stringcourse of the top plate and support plate and horizontal plane angle at an acute angle are 5 °~12 °, the angle
So that height adjusting and to draw nut stroke between ratio, it is proper, be conducive to the accurate control of camber.
Preferably, the top and bottom of the sliding block top plate is parallel with the stringcourse of support plate, it is conducive to sliding block movement,
In addition, increasing the support performance of device.
A kind of Bailey truss camber adjusts the application method of lowering device, drops dress in the adjusting of Bailey truss camber
It sets, top is provided with rectangular-ambulatory-plane binder and I-steel distribution stringer, and lower section is provided with support frame and support spar cap, by drawing spiral shell
The sliding that female and screw rod drawing may be implemented top plate rises, and realizes that camber is adjusted, finishes in construction, support frame is removed
When, the fastening nut at the both ends that come loose, which can be realized support frame and loosen, to be dropped.
In conclusion beneficial effects of the present invention:
1. a kind of Bailey truss camber of the present invention adjusts lowering device and its application method, compared to using top
Ask the speed being adjusted fast, jacking adjusts camber and need to carry out one by one, and full framing steel pipe is more, heavy workload, this adjusts dress
It is few to install quantity, rises and falls and adjusts convenience.
2. a kind of Bailey truss camber of the present invention adjusts lowering device, compared to using sand cylinder drop bracket by
Environment influences small, needs to carry out precompressed before sand cylinder use, but be influenced in use process by rainwater, will form after sand is moist it is hardened,
Can exist during later period decentering of scaffold and unload frame difficulty, and sand cylinder does not have camber regulatory function.
