Abstract
The utility model relates to the technical field of building shockproof and shock resistance, in particular to a three-dimensional rubber shake-insulating holder used in the engineering of building structure ar the bridge engineering. The main body is a rubber holder 4, and the bottom of the rubber holder is connected with a connecting plate 3. The rubber holder 4 and the connecting plate 3 are connected by a bolt, the connecting plate 3 and a lower steel bushing 2 is the relation of fit, and a vertical shake-insulating board 1 lies between the connecting plate 3 and a lower steel bushing 2. The advantages are that the utility model not only has the shake-insulating performance in the horizontal direction, but also is provided with the shake-insulating holderhaving the function of insulating the earthquake and shake in the vertical direction, in order to provide the minor horizontal stiffness and the vertical stiffness.
Description
Technical field
The utility model relates to shockproof, the anti-seismic technology field of building, particularly a kind of three-dimensional rubber earthquake isolation support that is applied to structural engineering or bridge engineering.
Background technology
Earthquake is a kind of natural calamity, and strong earthquake meeting brings huge disaster to the mankind, comprises casualties and economic loss.Historically, China's earthquake disaster occupies first of the world, is characterized in that frequency height, earthquake magnitude are big, it is wide to distribute.20th century, China took place more than six grades inferior surplus the earthquake 600.China 1/3rd above territories, big and medium-sized cities more than half are positioned at seismic fortification intensity 7 degree and the above area of 7 degree.At present, the earthquake of China is still very active, and 8 earthquakes more than 7 grades and more than 40 earthquake more than 6 grades have since nineteen ninety-eight taken place, and in February, 2003,6.8 grades of earthquakes of Bachu, Jiashi caused 1,300,000,000 yuans of direct economic losses.The earthquake that Iran's crust nurse takes place at the beginning of 2004 causes nearly 50,000 people's death.In addition, because of vibration such as blast, high wind and machinery, vehicle operating with impact the disaster and the environment pollution that cause and occur repeatedly, social economy and people's lives and properties are suffered heavy losses.
Seismic isolation technology is comparatively effective in the world novel earthquake resistant engineering new technology.The isolation structure system is by being provided with the shock insulation layer, structure is divided into superstructure, shock insulation layer and substructure three parts, seismic energy passes to the shock insulation layer via substructure, after being absorbed and consumed main seismic energy by the earthquake isolating equipment of shock insulation layer, only has the small part energy to pass to superstructure.Rubber earthquake isolation support is an earthquake isolating equipment representative in the seismic isolation technology, and it has very big vertical bearing capacity, and its horizontal rigidity is less, and the horizontal limeit displacement capabilities is bigger.Simultaneously, shock insulation rubber bearing has reduction with good ability and endurance quality.Formerly apply for a patent 200420043522.1,200420043521.7,200420043516.6 and disclose individual layer rubber earthquake isolation support, multilayer rubber shock isolating pedestal and the middle laminated rubber vibration isolation bearing that is provided with lead for retractable pencil respectively, above-mentioned bearing can only provide less horizontal rigidity, and vertical rigidity is big, and less vertical rigidity can't be provided.
Summary of the invention
The purpose of this utility model is to provide a kind of isolation property that not only has in the horizontal direction, at the shock isolating pedestal that the function of isolating earthquake and vibration is vertically also arranged, can provide less horizontal rigidity and vertical rigidity simultaneously simultaneously.
Effect of the present utility model realizes by following scheme:
The three-dimensional rubber earthquake isolation support of the utility model comprises that neoprene bearing, junction plate, vertical earthquake isolating plate reach steel bushing down, be characterized in that the neoprene bearing below is connected with junction plate, junction plate carries out a body running with following steel bushing matching relationship, and the vertical earthquake isolating plate places between the two above-mentioned.
Above-mentioned vertical earthquake isolating plate is individual layer rubber or multilayer laminated steel plate rubber, and less vertical rigidity can be provided, and in the cavity of vertical earthquake isolating plate between junction plate and following steel bushing, the vertical deformation of bearing mainly occurs on the vertical earthquake isolating plate.
Above-mentioned neoprene bearing can be General Purpose Rubber bearing or lead core rubber support.
Above-mentioned neoprene bearing is connected by bolt with junction plate.
Compared with prior art, advantage of the present utility model is;
(1) increased the vertical earthquake isolating plate on the basis of original higher hardness neoprene bearing, made whole bearing not only and less horizontal rigidity arranged, vertical rigidity is less simultaneously;
(2) can realize the three-dimensional isolation effect behind the structures isolation effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: vertical earthquake isolating plate 1, following steel bushing 2, gusset piece 3, neoprene bearing 4.
The specific embodiment
Structure of the present utility model as shown in Figure 1, main body is a neoprene bearing 4, neoprene bearing below is connected with junction plate 3, neoprene bearing 4 and junction plate 3 are connected by bolt, junction plate 3 and following steel bushing 2 are matching relationship, vertical earthquake isolating plate 1 places between the two above-mentioned.Vertical earthquake isolating plate 1 is multilayer laminated steel plate rubber, and length is 620mm, and rubber is 5 layers * 15mm, and steel plate is 4 layers * 3mm, and elastomeric material is the soft natural rubber of shear modulus G value 0.39MPa.Neoprene bearing 4 is multilayer laminated steel rubber abutments, and the centre is provided with lead for retractable pencil, and the length of bearing is 620mm, lead core diameter is 120mm, inner steel plate is 42 layers * 2mm, and inner rubber is 43 layers * 4.0mm, and elastomeric material is a hardness natural rubber among the 0.55MPa for the shear modulus G value.
Claims (4)
1, a kind of three-dimensional rubber earthquake isolation support, its main body is neoprene bearing (4), it is characterized in that neoprene bearing (4) below is connected with junction plate (3), and junction plate (3) is a matching relationship with following steel bushing (2), and vertical earthquake isolating plate (1) places between the two above-mentioned.
2, three-dimensional rubber earthquake isolation support according to claim 1 is characterized in that described vertical earthquake isolating plate (1) is individual layer rubber or multilayer laminated steel plate rubber.
