The aim is to widen the computing range of the device, prolong period, and reduce and avoid the property and manpower damage which can be brought in an earthquake. A movable supporting ball is a circular sphere, the upper surface of a dissipative sphere 2 is provided with a sliding-resistant layer, and an upper and a lower contact surfaces form spherical surface shapes. The utility model has the advantages that the computing range of the whole device is widened according to an adjustable parameter, and the utility model can be slid in a wide period to expect vibration isolation.

Description

Novel building shock insulation energy-dissipating device

The utility model is related to a kind of novel building shock insulation energy-dissipating device that prevents earthquake and design.

In background technology, for the disaster that prevents that earthquake from bringing to building, the past adopts ways such as increasing fabric structure rigidity to come " antidetonation "; Now think mostly that the way of employing shock insulation is comparatively rationally desirable, the method for shock insulation is exactly between upper building and base foundation, sets up the shock insulation layer, to increase the natural period of building, avoids the predominant period of earthquake, alleviates vibrations.In order to prolong the building natural period, normally between building and basis, movable support is set at present, just the earthquake response acceleration can reduce greatly, otherwise but, displacement response will increase; For reducing displacement, add the damper that stops its motion again, the while is earthquake energy also, is again shortened in the cycle; If because of the adding of damper does not change the cycle substantially, the reaction acceleration that earthquake produces has only decline seldom, and this will cause earthquake isolating equipment to have only very narrow computer capacity.

The purpose of this utility model is a kind of novel building shock insulation energy-dissipating device of design, expands its computer capacity effectively, the prolongation cycle; alleviate vibrations, improve the anti-seismic performance of building, protection country; collective and personal property reduce and avoid property and damage to person that earthquake brings.

Technical solution of the present utility model is as follows:

Be included between building 10 and the material foundation 7 supporting and the damper of placing shock insulation, it is characterized in that: for damper and have the power consumption spheroid 2 surface-mounted anti-skid layers 3 of supporting role concurrently, the contact surface of power consumption spheroid 2 upper and lowers is a dome shape.

Technical solution of the present utility model also comprises:

Supporting is circular spheroid for the ball 1 of movable support,

The ball 1 that distributes contacts the steel plate 9 that can manage in advance up and down.

Power consumption spheroid 2 upper surfaces and anti-skid layer 3 are formed spherical surface.

Power consumption spheroid 2 upper surfaces and anti-skid layer 3 are formed curved surfaces

Description of drawings of the present utility model is as follows: Fig. 1 is first kind of structural representation, and Fig. 2 is second kind of structural representation, and Fig. 3 is the plane device schematic diagram, and Fig. 4 is that building uses schematic diagram.Above-mentioned number in the figure is described as follows: 1-spin, the 2-spheroid that consumes energy, the anti-skid layer of 3-, the 4-rubbing surface that consumes energy, the 5-frictional layer that consumes energy, 6-ground, 7-traditional material basis, 8-building base plate, 9-steel plate, 10-building.

Following adjoint is described in further detail: referring to Fig. 1, ground is traditional ground, as original soil, it on ground 6 traditional steel concrete traditional material basis 7, fill power consumption frictional layer 5 in 7 spills (curved curved surface or other geometry) groove of concrete traditional material basis, its jointing material has been the wrapped strengthening effect, as building mortar etc., power consumption frictional layer 5 spill sphericals are power consumption rubbing surfaces 4, this face contacts with power consumption spheroid 2 bottoms, spherical in shape contact of both contact surfaces makes power consumption spheroid 2 realize the little rotation of all directions, and power consumption rubbing surface 4 is to rub and lead 5 material and be bonded by forming power consumption; The anti-skid layer 3 of power consumption spheroid 2 upper surfaces assembling, both form sphere shape, and anti-skid layer 3 is by rubber or other anti-skid material, the anti-skid layer 3 contact supporting building base plate 8 of spherical surface; The ball 1 upper and lower surface contact steel plate 9 that Fig. 1 is upper left, steel plate 9 is provided with for local pressure is excessive, it is concrete embedded steel plate 9, the corresponding diagram right side is that ball 1 upper and lower surface directly contacts building base plate 8 and material foundation 7, ball 1 and power consumption spheroid 2 upper surfaces are jointly as movable support, power consumption spheroid 2 also plays the friction-type damper, and power consumption spheroid 2 is to be made by concrete or steel concrete, and ball 1 can adopt other material such as steel ball or steel concrete.According to actual conditions, between building 10 and traditional material basis 7, can not adopt 1 supporting of rolling, only adopt 2 supportings of power consumption spheroid.Referring to Fig. 2, the same substantially, different is that power consumption spheroid 2 is not a spheroid, but the bottom contact surface is a spherical surface, and upper surface and anti-skid layer 3 are formed spherical surface.Certainly also can adopt cambered surface.Referring to Fig. 3, power consumption spheroid 2 distributes with ball 1 together and can be symmetric form, also can be uniform, also can be asymmetric, non-uniform, is that design style and the gravity centre distribution according to building 10 decides here.What play supporting referring to Fig. 4 mainly is power consumption spheroid 2, distributes at building 10 middle parts, and this point Fig. 3 also shows.

Advantage of the present utility model and effect are as follows:

1. owing to the power consumption spheroid and the balls that adopt different sizes, so according to the ratio between its quantity, really Decide the coefficient of friction of rubbing surface, many adjustable parameters such as big low height of power consumption spheroid have all been expanded whole dress Put the scope of calculating.

2. because widening of designing and calculating scope makes whole earthquake isolating equipment slidably, in the prolongation cycle, alleviate Vibrations, and make displacement in allowed limits; Slidably install according to actual conditions simultaneously, can design Various building self-vibration periods, this is outstanding so have the shock insulation that waits in expectation in quite wide periodic regime Effect.

3. in conjunction with all multi-parameters of power consumption spheroid, realize by in, small earthquake sets out, until resist the earth The isolating affection of the large deformation of shake.
