Description

Anti-earthquake device for buildings

The utility model relates to inhabitation, purpose anti-earthquake device for buildings such as office.

Now Chinese and foreign every country be used to live, the building of purpose such as office, big to consumed resources such as soil, constructional materials, the energy, funds, pollute social environment problem ability such as traffic jam and prevent and resist serious natural calamity such as earthquake, flood, typhoon and prevention and administer.The basic reason that causes this consequence is the method for designing of these buildings, and according to the requirement of this method for designing, the main usage space of building is all wanted to adopt natural light.According to the building of this requirement design, its length and wide size just must be limited in the very little scope, in order to increase building area, can only hoist development so " skyscraper " occurred, but excessive height is unfavorable for antidetonation, for satisfying shockproof requirements, need to increase steel, constructional materialss such as cement raise building cost significantly, and the height of building is near the limit, this building is exactly the traditional architecture thing, can be described as little depth building.The environmental benefit of the demand for development building of society is better, and makes rational use of resources.In order to reach this requirement, the principle of the daylighting first in the method for designing that just must discard tradition has been broken away from this restriction, can obtain the better synthesis social effect.

The purpose of this utility model is: a kind of building aseismicity device is provided, and it is the reasonable use resource more, and environmental benefit is better, improve the ground utilization rate, make building both have the optimum structure of resisting external stress, can have good stability again, reduce the destruction of earthquake building.

The purpose of this utility model is achieved in that

A kind of anti-earthquake device for buildings, it comprises: spacer medium, isolation tank, it is characterized in that: superstructure separates with the basis, and the basis is provided with end face, and superstructure is provided with the bottom surface, end face and bottom surface are the plane, be separation layer between the bottom surface of superstructure and basic end face, described basic end face is greater than superstructure, and its edge is provided with the edge of projection, the basis end face is a shallow pool shape, promptly be provided with isolation tank, run off, put into spacer medium in the isolation tank to prevent spacer medium, it can be one deck sand, form separation layer, superstructure is located on the spacer medium, and separation layer is separated superstructure and basis; The profile of superstructure equates substantially with wide that for long higher primary school is in equaling long or wide.The section of described superstructure is regular polygon or circular cylinder, has the whole top and the end.

A kind of removable superstructure that adopts the described anti-earthquake device for buildings of claim 1, it is characterized in that: the bottom margin of described superstructure, be provided with a plurality of firm pre-buried hook or built-in fittings, itself and superstructure bottom surface are built and are one, when moving this building, set pre-buried hook or built-in fitting are connected with pulling equipment.

The utlity model has following advantage and good effect:

Because its structural strength height, add separating of superstructure and basis, prevent and resist earthquake, the ability height of disasters such as ground fissure.

Traditional method for designing is placed on consequence to daylighting, in order to meet this requirement, building can only be little depth, the utility model has been broken away from the constraint of the principle of daylighting first, so can be big according to resisting the external force action intensity, the requirement design of good stability also can make superstructure separate with the basis, thereby more help antidetonation.

The existing building field all is to strengthen basis and being connected of superstructure as possible, usually its connecting part is provided with collar tie beam, the beam column stirrup is encrypted, bar splicing or welding, the assurance steel bar continuous is stressed, this is the inevitable outcome of existing design philosophy, but the utility model is separated basis and superstructure, mutual connection changes relative flexibility into and connects by being rigidly connected, it highly realizes the stability of building by suitable control, thereby play the effect of antidetonation, the isolation tank of basic end face is designed to pond shape structure, though this shape is simple, but this shape and separation layer are configured between building foundation and the superstructure, this is inconceivable for the existing building technology, so it has overcome the prejudice of industry, has constituted practical new technical scheme.

Fig. 1 is a schematic diagram of the present utility model.

Describe the utility model in detail below in conjunction with drawings and Examples.

Accompanying drawing is a schematic diagram of the present utility model, among the figure: isolation tank 1, spacer medium 2, basis 3, superstructure 4, aproll 5; Isolation tank can be divided into again: at the bottom of the pond 101, the base 102 of encorbelmenting, vertical pool wall 103.

Isolation tank 1 can be following several structure:

A. isolation tank is a prefabricated component, can be divided into some, after build up on the basis, assembles up at basic end face, forms the isolation tank of pond shape.

B. at the bottom of utilizing basic end face for the pond of isolation tank 101, encorbelment base 102 and vertical pool wall 103 is prefabricated component, can be divided into some, be prefabricated into that shape is similar cornices, but " L " shape member that its vertical pool wall 103 is increased, mounting method is also similar to cornice, and with the welding of base roof plate embedded part, forms isolation tank.

C. 101 utilize base roof plate at the bottom of the isolation tank pond, encorbelment base 102 and vertical pool wall 103 of isolation tank is cast for one with top board during basic top plate construction, is cast-in-place structural, forms the overall isolation pond.

Spacer medium 2 can be sand, also can be other particulate material; The design and the construction method of basis 3 and superstructure 4 can be similar to traditional architecture, and the treatment principle on basis is also similar substantially to conventional method, but superstructure is separated by separation layer with the basis.

Because the profile of superstructure equates substantially with wide that for long higher primary school is in equaling long or wide, the good stability of building on the old place can make superstructure separate with the basis, and this separation is particularly conducive to the shock resistance of building.For the earthquake stress of horizontal direction, it works to regulate the friction between superstructure and basis; When stress does not have destruction to building on the ground, can move with the basis; When stress reaches when on the ground building has destruction, should allow superstructure not with foundation motion, thereby reduce the destruction of earthquake, answer for vertical, it should make superstructure can break away from the basis, thereby eliminate under the effect of rising stress, the basis is pushed into peak to superstructure, oneself begin to descend, and superstructure continues to rise under effect of inertia, the effect of the tensile stress that between occurs, and this effect is the main destructive power that causes superstructure impaired, because the compressive strength of any material all substantially exceeds hot strength.

Main design of the present utility model is that superstructure is separated with the basis, the concrete mode that adopts is to be provided with separation layer between the two, put into spacer medium in the isolation tank, form separation layer, this device is that isolation tank is arranged on the basic end face with linking of basis, and do not relate to the basis building structure, no matter i.e. which kind of basis, as long as form the plane at its end face, cast-in-place again or be assembled into isolation tank on this plane by prefabricated component, certainly also can use basic end face as the isolation tank bottom surface, need only build bottom surface, pond and the isolation tank facade pool wall of choosing part again.That is to say that this device is just on basic end face, rather than be included in the basis, this device is arranged on the basic end face and the antishock device between the superstructure bottom surface, and it is the member that is used to build, be not building itself, and this to build on the ground be transportable.

The utility model superstructure separates with the basis, superstructure can be various structure typess, as reinforced concrete structure, steel work, box-shaped structure, light body structure, for box-shaped structure, yes can be moved for it, for other several structures, if construction scope is little, because it separates with the basis, mode described in available next section is moved, if construction scope is very big, just need abundant oversized equipment could move it, and mobile expense can be very high, less economical, generally can this not do, if but special requirement is arranged it is still and can be moved, so building on the ground, this can be moved.

After adopting superstructure of this device to build on the basis, this superstructure moves if desired, can build second basis nearby, this superstructure is gone on second basis, even can also move on the 3rd basis again.The bottom margin of described superstructure, there are not a plurality of firm pre-buried hook or built-in fittings, itself and superstructure bottom surface are built and are one, when moving this building, set pre-buried hook or built-in fitting are connected with pulling equipment, and be pulled to by pulling equipment on another basis in precalculated position, pulling equipment can be large-scale hoist engine, crawler tractor.Such superstructure is not can only be corresponding to a basis, do like this is highly significant, because the city is constantly development, along with increasing of building, road also needs to widen, when widening road, building in the near Systems of Red Line in Planning Based of road has only dismounting, produces waste, if adopt this device, when improving shock resistance, give way for highway if desired, only need outside Systems of Red Line in Planning Based, to build backward another basis, superstructure is moved on to continue on the new basis to use, reduce waste, produced good economic benefit.
