Description
Technical field
The invention belongs to building structure vibration damping and vibration isolation field, particularly a kind of spiral three-dimensional isolation mounting.
Background technology
Development of modern industry is rapid, and city size constantly expands, and makes urban track traffic become the important means solving urban traffic.Rapidly, while building subway, the noise and vibration problem caused due to subway circulation displays gradually in track traffic development.Especially in Beijing, Shanghai and these scales of Guangzhou are large, traffic problems are serious city, subway is developed rapidly, but runs through center, city due to subway, and this causes tremendous influence to the comfortableness of building safety around along the line and house.The environmental problems such as the vibration of building that subway train operationally causes cause the attention of people.Vibration induced by underground trains is outwards propagated by surrounding formation, this can bring out the secondary vibration of neighbouring underground structure and adjacent structure, very unfavorable to the safety of structure, can cause low-frequency noise in some building basements, cause the discomfort of human body, this has a strong impact on people's Working Life.
On the other hand, China is in the joint place of Mediterranean South Asia earthquake belt and this two violent earthquakes band of circum-Pacific seismic belt, more than 70% of territory is all in earthquake zone, here more than 2/3 of the big and medium-sized cities of more than provincial capital 23 and a population of one million is included, and people in the countryside have 800,000,000,6.5 hundred million inhabitants live are wherein in Areas of High Earthquake Intensity district.China's earthquake takes place frequently, and multiple shallow-focus earthquake, have high, the destructive large feature of earthquake intensity, this makes China become one of the most serious country of earthquake disaster, and therefore the building protection situation of China is very severe.
Antidetonation is the most effectively conceived to be that works and ground are kept apart, and when there is earthquake, both can ensure the safety of structure, can the installations and facilities of operator guards inside not be damaged again.At present, what vibration isolation technique mainly solved is that level is to vibration damping problem, horizontal vibration isolating suspension is also difficult to the function realizing vertical vibration isolation, reason is for vertical vibration isolation technology, vertical bearing capacity needs to bear superstructure deadweight, and vibration isolation technique needs to have less vibration isolation rigidity, material is thus formed the contradiction of larger supporting capacity demand and less vibration isolation rigidity requirement, this also makes this isolation mounting be difficult to realize.Nowadays some scholar attempts alleviating horizontal and vertical seismic loads in the lump by inventing a kind of stable three-dimensional isolation bearing, such as, and disk spring, air spring and hydraulic oil.Wherein some three-dimensional vibration isolating device all has good vertical vibration isolation performance or damping capacity, but the shortcoming such as expensive, bulky of these equipment can not be ignored, and the extensive use of three-dimensional vibration isolating device is restricted.
Summary of the invention
For the defect that prior art exists; the object of the present invention is to provide a kind of spiral three-dimensional isolation mounting; that one isolates three dimensional earthquake and the novel isolation mounting of ambient vibration simultaneously; the vibratory response under earthquake or effect of vibration of the protected structure of this device or equipment and vibration passing is adopted to be effectively controlled, the safety of structure or equipment under protection earthquake or effect of vibration.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of spiral three-dimensional isolation mounting, comprises steel center pillar, steel urceolus, inside spin steel plate groove, rubber layer and inside spin steel plate; Described steel center pillar and steel urceolus concentric shafts are placed; Described steel center pillar and inside spin steel plate are whole cast, and described steel urceolus is connected for holing with inside spin steel plate groove, and described inner prop spiral steel plate is placed among inside spin steel plate groove, and occlusion is corresponding; After described rubber layer is bondd by sulfuration process and inside spin steel plate top and bottom, the another side of rubber layer is bondd by sulfuration process and inside spin steel plate groove again; Gap is there is between described inside spin steel plate groove and inside spin steel plate.
The pitch of described inside spin steel plate is chosen between 60mm to 100mm, the angle between the normal direction of described inside spin steel plate and steel center pillar axis between 5 ° to 15 °, to avoid too small vertical deformation and excessive vertical deformation.
Described rubber layer is that high-damping rubber material is made to ensure enough energy dissipation capacities.
Compared with prior art, the present invention has following outstanding advantage:
A kind of spiral three-dimensional isolation mounting of the present invention, makes structure level and vertical direction vibration be controlled, give full play to the ductility of rubber and the rigidity of steel plate, and all directions does not interfere with each other mutually.This device can adjust the angle of spiral steel plate, thus adapts to different displacement and load, can meet different loads and not change its size to be used in common building thing, special construction, bridge and plant equipment vibration damping.In addition, with other three isolation mountings as butterfly spring is connected compared with neoprene bearing, good integrity of the present invention, simple structure, has good stability and safety.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are further described.
As Figure 1-Figure 8, a kind of spiral three-dimensional isolation mounting, comprises steel center pillar 1, steel urceolus 2, inside spin steel plate groove 3, rubber layer 4 and inside spin steel plate 5; Described steel center pillar 1 is placed with steel urceolus 2 concentric shafts; Described steel center pillar 1 is whole cast with inside spin steel plate 5, and described steel urceolus 2 is connected for holing with inside spin steel plate groove 3, and described inner prop spiral steel plate 5 is placed among inside spin steel plate groove 3, and occlusion is corresponding; After described rubber layer 4 is bondd by sulfuration process and inside spin steel plate 5 top and bottom, the another side of rubber layer 4 is bondd by sulfuration process and inside spin steel plate groove 3 again; Gap 6 is there is between described inside spin steel plate groove 3 and inside spin steel plate 5.
The pitch of described inside spin steel plate 5 is chosen between 60mm to 100mm, the angle between the normal direction of described inside spin steel plate 5 and steel center pillar 1 axis between 5 ° to 15 °, to avoid too small vertical deformation and excessive vertical deformation.
Described rubber layer 4 is made to ensure enough energy dissipation capacities for high-damping rubber material.
The course of work and the principle of this device are as follows:
During horizontal direction geological process, gap 6 is there is between described inside spin steel plate groove 3 and inside spin steel plate 5, tolerable levels is out of shape, and rubber layer 4 can produce distortion and absorbs the vibration of horizontal direction and consume energy, and after distortion, viscous daming material rubber layer 4 produces tensile stress provides restoring force.Vertical bearing capacity is provided by inside spin steel plate groove 3, during vertical uniform load q, inside spin steel plate groove 3 and inside spin steel plate 5 are along the oblique transmission vertical force of slide plane, produce torsional deflection, now rubber layer 4 produces the distortion along sliding surface direction, produce reversal interlocking relay simultaneously and restoring force is provided, in deformation process, absorb Vertical Vibration Energy power consumption.
