Description
Technical field
The present invention relates to technical field of bridge construction, be specifically related to adjusting apparatus and the installation method of a kind of bridge STU antishock device.
Background technology
At present, China, in terms of Bridge Earthquake Resistance Design, is usually to use and strengthens a certain pier stud (being usually fixed pier stud) cross section
Way, is made the vibrations load on all bridge plates, is passed on hold-down support by the movable bearing support under bridge plate, plate, then pass through
Hold-down support passes on fixing pier stud, then passes on basis, ground.
This kind of force transfer system, also exists following four drawback: one all of vibrations load all by fix pier stud and under consolidate
Determine bearing, basis, ground undertake, and the earthquake load that they undertake is more much greater than other pier stud, and once anchor block damages,
Bed rearrangement bridge is almost scrapped；Its two power transmissions circuit lengthens significantly, and it is existing that bridge plate is susceptible to Cross deformation under seismic loading
As so that power transmission is the most reliable；The energy of its three seismic wave cannot discharge, and earthquake load also cannot alleviate；It four once finds
Problem, maintenance difficult is big, costly.If installing STU antishock device, going wrong, only its local replacing need to be keeped in repair
Extremely easy, expense is the lowest, and STU antishock device makes bridge by burst effect such as load such as earthquake load, impact load etc.
During appearance, STU, then by bridge plate and one piece of tight pinning of pier stud, does not allow bridge plate longitudinally produce vibration.And bridge is when normal
Displacement such as temperature, creeping then will not be impacted.
At present, in the installation process of STU antishock device, core is the length adjustment i.e. STU antidetonation dress of STU antishock device
Put the adjustment of middle piston bar position, but invisible during position that piston is in cylinder body, and part is big and heavy, directly
Measure less than, can only indirectly carry out, length adjustment is specifically divided into machinery adjust and heat adjust:
A. machinery is adjusted to: (weight of each STU antishock device is about to hang out STU antishock device with the calabash more than 6T in case
For 2.8T), it is placed perpendicularly in a steel frame made in advance, framework must have enough strength and stiffness, and inwall is each
Face is all good with sponge or gauze pad, unclamps the interim setting tool scribbling red paint above STU antishock device, unclamps STU and resists
The dust cover of shake device movable end, and the fixing end of STU antishock device is landed, slowly pull calabash, turn movable head with hands,
Making screw thread exposed length on piston rod is 31.75mm (about 32mm), and this is the design ideal position residing for movable head, slings
Purpose is to reduce the friction between screw thread, it is simple to turn with hands.Tighten the interim setting tool scribbling red paint above STU.
B. heat is adjusted to: whether the distance between pin-and-hole and the pin-and-hole of fixing head of the movable head of inspection STU antishock device reaches H,
(it is called for short if less than H, then movable head vertically being sling and just hangs), if more than H, then fixing head vertically being sling (being called for short counter hanging),
Make movable head land, then unclamp hoist cable, the cylinder body of STU antishock device or piston rod and phase slowly can occur under gravity
To motion, until H reaches predetermined distance, at once stop.This ensures that there piston rod in the cylinder body of STU antishock device
Position.When just hanging, movement velocity hourly is about 1/8～1/4 inch, counter hang then slowly the most, it may be necessary to just hanging 2～3 times time
Between.After being adjusted in place, should immediately piston rod be fixed with outer surface of cylinder block temporarily.
