Abstract

The utility model relates to the technical field of buildings, in particular to a strong earthquake resistant building foundation structure, which mainly consists of an upper, a middle and a lower steel structures. The building foundation structure is characterized in that a plurality of horizontal lateral runners are arranged between an upper and a middle layers , and large steel balls are arranged in the runners; a plurality of horizontal longitudinal runners are arranged between the middle and a lower layers, and large steel balls are arranged in the runners; the lower steel structure foundation is fixedly connected with a foundation; and the upper steel structure foundation is fixedly connected with a building. The utility model has the advantages that when a strong earthquake occurs, vibration waves from any direction bring relative displacements between the lower foundation and the middle foundation as well as the middle foundation and the upper foundation when passing through the building foundation; the horizontal vibration wave with huge destructive power can be fully absorbed by the building foundation , so that the building built on the foundation does not move at all without being damaged.

Description

The anti-foundation structure of building that shakes doughtily

[technical field]

The utility model relates to technical field of buildings, specifically a kind of anti-foundation structure of building that shakes doughtily.

[background technology]

When earthquake took place, the wavelength-division that is transmitted to ground by focus was two kinds: P ripple and S ripple, promptly so-called " vertical vibration ripple " and " horizontal vibrating ripple ".The horizontal vibrating ripple is huge to building destruction power, and the mass casualties causes because building collapses exactly.The vertical vibration ripple causes the landslide easily, thereby blocking-up traffic and river will cause traffic jam and barrier lake to form.And present building trade does not also have a kind of foundation structure of building can effectively prevent in the macroseism building appearance of collapsing.

[summary of the invention]

Task of the present utility model overcomes the deficiencies in the prior art exactly, a kind of anti-foundation structure of building that shakes doughtily is provided, by changing the foundation structure of building design, horizontal vibrating ripple and vertical vibration ripple when making building foundation can absorb the earthquake generation fully, thus make building safe and sound when shake takes place doughtily.

The utility model adopts following technical proposals: a kind of anti-foundation structure of building that shakes doughtily, mainly form by the upper, middle and lower-ranking steel work, it is characterized in that: be provided with some routine horizontal cross chutes between upper strata and the middle level, large-scale steel ball is housed in the chute, between middle level and lower floor, be provided with the vertical chute of some routine levels, large-scale steel ball is housed in the chute, and lower floor fixedlys connected with ground on the steel work basis, fixedlys connected with building in steel work basis in upper strata.

The periphery is provided with retainer plate Beam around the described building, circle Beam and on, powerful nitrogen hydraulic spring grease cup is housed between the steel work of middle level, the excusing from death pitch of waves is housed from sensor and inductance displacement sensor between building and circle Beam, powerful nitrogen hydraulic spring grease cup, the excusing from death pitch of waves are connected computer control with inductance displacement sensor by control circuit from sensor.

The upper strata adopts the fixed lock of rail pulley to be connected with middle interlayer and middle level respectively with following interlayer.

The beneficial effects of the utility model are: when violent earthquake took place, the horizontal vibrating ripple that any direction transmits during by this building foundation, all showed as the relative displacement between subfoundation and basis, middle level and middle level basis and basis, upper strata.The huge horizontal vibrating ripple of destructive power wherein, absorbed fully by the building foundation in the utility model fully, make the building of building on this basis motionless and exempt from destruction, designed retainer plate Beam around the building, powerful nitrogen hydraulic spring grease cup is installed on circle Beam and the basis, between the slide block of middle level, thereby solved building because powerful windage and ground inclination cause the irreversible displacement problem of building, also can not occur building super highrise building and the too small building that causes of foundation area is toppled over phenomenon.

[specific embodiment]

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

Referring to accompanying drawing, building foundation of the present utility model is divided into upper, middle and lower-ranking; Three layers are steel work, are the chute of directions X design by horizontal cross between upper strata and the middle level, arrange large-scale steel ball in the chute, and steel ball size changes according to the building floor height, and steel ball can be made the positive negative displacement of directions X; Vertically be the chute of Y direction design by level between middle level and the lower floor, arrange large-scale steel ball in the chute, steel ball can be made the positive negative displacement of Y direction, and lower floor fixedlys connected with ground on the steel work basis, and the upper strata steel work is basic fixedlys connected with building.

The gravity friction factor of building self, the typhoon below 12 grades that can contend with substantially, the monolateral windage that causes to building.But, in order to eliminate and prevent to surpass windage or ground inclination more than 12 grades, and produce the monolateral irreversible displacement problem of building.The utility model has designed retainer plate Beam around the building, between the going up of circle Beam and basis, middle level slide block powerful nitrogen hydraulic spring grease cup is installed, and causes the irreversible displacement problem of building thereby solved building because of powerful windage and ground inclination.Between building and circle Beam, design and installation the excusing from death pitch of waves from sensor and inductance displacement sensor, sensor is passed monitored data back in real time to computer, monitored data surpass set index after, computer control hydraulic pressure nitrogen spring is revised and is resetted.

Fig. 4 is that steel work upper strata, basis and middle level, steel work basis steel ball are arranged schematic diagram, and the positive negative displacement of directions X can be made in basic upper strata and basic middle level.

Fig. 5 is that steel work basis lower floor and middle level, steel work basis steel ball are arranged schematic diagram, and the positive negative displacement of Y direction can be made in basic lower floor and basic middle level.

As shown in Figure 6: whole ground basic displacement direction: the directions X displacement adds the displacement of Y direction and equals the displacement of Z direction.

Fig. 9 is the schematic diagram that concerns that prevents that building from toppling over, and earthquake proof foundation relative displacement mutually also will prevent to build super highrise building and foundation area is too small, the problem that causes building to be toppled over! Below design has solved the problems referred to above:

Upper strata, steel work basis and middle interlayer by the rail pulley of directions X shift reciprocately, with the upper strata and the middle level primary relationship is fixed and middle level and following interlayer, by the rail pulley of Y direction shift reciprocately, are fixed middle level and subfoundation relation.Both can carry out relative displacement between every layer of the basis, the gap between having fixed every layer again.Prevent that foundation area is too small because building super highrise building, the problem that causes building to be toppled over.
