There is very big harm, it can make the structures such as cored slab be distorted during operation, cored slab increases extra internal force, in addition
When fulcrum comes to nothing, vehicle process can produce huge shock, and make structure twist phenomenon.Both phenomenons can be tied to bridge
Structure and environment have larger negative effect.After setting a roof beam in place, if finding, fulcrum is unreal or phenomenon of coming to nothing, and most of units in charge of construction can listen
Appoint it, will not typically make any process.Because solving fairly cumbersome.Even if running into responsible unit in charge of construction or prison
Reason, in the amount of coming to nothing than in the case of larger, one block of steel plate can be filled at place of coming to nothing using pading plate in the form of, as to whether padding
, few people go to manage him.For example, a seat empty 28mm, workmen can look for the billet of one piece of 20mm or 30mm to go
Pad, the billet of 30mm go plug certainly not enter, can only be with the billet of one piece of 20mm, therefore the hidden danger come to nothing still is present.
Say again, the billet of insertion is run in journey on bridge with vehicle, will not loose or dislocation or corrosion every how long.At present I
