Description
Technical field
It the present invention relates to structural fortification field, is particularly suitable for reinforcing existing floor, improves dynamic equipment floor
The comfort of floor vibration.
Background technique
In recent years, Frequent Accidents are vibrated, structural vibration problem more attracts people's attention.Often match in industrial production workshop
For large-sized power plant, vibration problem is even more commonplace in industrial production, not only directly affects normal industrial production, together
When serious threat also is caused to the physical and mental health of staff.Vibration institute with the rise of Building Trade in China, in engineering
The problem of bringing is also more and more, and wherein influence of the large-sized power plant to industrial premises and surrounding enviroment is commonplace, makes
At loss it is even more self-evident.Because of technique production requirement, large-sized power is equipped in many industrial production workshops in China and is set
It is standby, often because reasons, the machinery equipments such as design carelessness, the update of equipment, the change of production technology, structure aging are vibrated to workshop
Structure brings safely many detrimental effects, and less serious case causes equipment itself to be unable to operate normally and produce, serious, causes
The destruction of mill construction.And increasing with multi storied industrial factory building, large machines be arranged on floor become one can not
The trend avoided has important social and economic benefit.Because equipment is directly arranged on structure, the vibration of equipment is directly led
The vibration of mechanical floor floor is caused, if the structure floor natural frequency of vibration and vibration equipment frequency are close, the resonance of floor will be caused, produced
Raw vibration enlarge-effect, leads to structural damage.Therefore, become engineering circles for the reinforcing problem for having mechanical floor flooring urgently to solve
Certainly the problem of.
Currently, there are mainly three types of common reinforcement means: increasing rigidity of structure method, sorting capacity method, steel bonding/carbon fiber
Tie up method for strengthening.Increasing the most common method of rigidity of structure method has increasing member section method, and such method construction technology is simple, adapts to
Property it is strong, but the situ wet operation time is long, influences space utilization, and such method is bad for the consolidation effect of floor；Change and passes
Power approach method usually realizes that such method can effectively reduce the stress of component by extension supporting, reduces the deformation of member, but
Such method is limited to the arrangement form of existing structure, and difficulty of construction is higher；Steel bonding/CFRP Sheet Strengthening Method construction technology is easy,
But it is only applicable to bear the reinforcing of Static behavior and the component in normal humidity environment.In the method that underfloor increases secondary beam newly
It can effectively improve the rigidity of structure, mitigate vibration of floor, but work together the two can, undertake superstructure together
The load transmitted is the key point of this kind of reinforcement means.Therefore, inventing one kind makes to assist between existing floor and reinforcement
Displacement-adjustable attachment device with work is very necessary.
