Abstract
The utility model discloses a quakeproof strip foundation. The strip foundation comprises a strip grade beam and a foundation beam which are arranged separately. A certain gap is formed between the strip grade beam and the foundation beam above the strip grade beam. Spherical grooves are uniformly formed in the strip grade beam, pressure-resistant balls are uniformly arranged on the foundation beam correspondingly, outer diameters of the pressure-resistant balls are smaller than inner diameters of the spherical grooves, and the pressure-resistant balls are embedded in the spherical grooves. Reflexed edges 30cm in width are arranged on two sides of the strip grade beam, and heights of the reflexed edges are consistent with the thickness of a mattress layer in a composite foundation. According to the quakeproof strip foundation, the strip grade beam and the foundation beam are arranged separately, so that the strip grade beam and the foundation beam can move relatively. During an earthquake, the strip grade beam can move along a vibration direction, so that destruction of the earthquake can be relieved; and when the earthquake stops, the pressure-resistant balls and the foundation beam can return to original positions under the action of own gravity, so that effects of earthquakes on buildings are reduced, and multi-directional quake isolation can be achieved.
Description
Technical field
The utility model relates to a kind of bar shaped shock insulating foundation structure, is particularly useful for strengthening the antidetonation of building.
Background technology
Housing construction adopts special-shaped column structure or shear wall structure to design in order to obtain the better space effect usually, and this class formation often adopts strip foundation, so strip foundation is used increasingly extensive in the housing construction field; But the strip foundation structure can not bear because the displacement that diastrophism brings is restricted and existing isolation structure designs than complexity and cost is too high.
Summary of the invention
The purpose of this utility model is the problem at prior art, provides a kind of simple in structure, and cost is low, effective a kind of shockproof strip foundation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of shockproof strip foundation, comprise strip foundation beam and grade beam, strip foundation beam and grade beam split arrange, between strip foundation beam and the top grade beam certain clearance is arranged, evenly be provided with ball recess on the strip foundation beam, on grade beam, evenly be provided with the resistance to compression spheroid accordingly, the external diameter of resistance to compression spheroid is less than the internal diameter of the ball at ball recess place, the resistance to compression spheroid is embedded in the ball recess, being provided with width in the both sides of strip foundation beam is turning edge of 30cm, the consistency of thickness of mattress layer in the height that turns edge and the composite foundation.
Above-mentioned shockproof strip foundation is provided with lubricating layer between resistance to compression spheroid and ball recess.
Above-mentioned shockproof strip foundation, described lubricating layer is polytetrafluoroethylene floor.
Above-mentioned shockproof strip foundation, the centre of sphere of described resistance to compression spheroid overlaps with the centre of sphere of ball recess.
Above-mentioned shockproof strip foundation, strip foundation beam contact with grade beam around be provided with damping rubber block.
Adopt technique scheme, the utility model has following advantage: owing to be the split setting at strip foundation beam and grade beam, and strip foundation beam and grade beam arrange by resistance to compression spheroid and the mutual buckle of ball recess, but make this two parts relative motion, when earthquake takes place when, the strip foundation beam can move along direction of vibration, thereby alleviated the destruction of earthquake, when earthquake stops, resistance to compression spheroid and grade beam are under the effect of self gravitation, can return to original position lentamente again, reduce the influence of earthquake to building, can realize multi-direction shock insulation.This foundation structure is simple, and certain reset function is arranged, and cost is low, and is effective, has practicality widely in the art.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is another kind of structural representation of the present utility model.
The specific embodiment
As Fig. 1, Fig. 2 and a kind of shockproof strip foundation shown in Figure 3, comprise strip foundation beam 2 and grade beam 3 that split arranges, between strip foundation beam 2 and the top grade beam 3 certain clearance 7 is arranged, the size in gap is decided according to comprehensive parameters.Evenly be provided with ball recess 4 on the strip foundation beam 2, on grade beam 3, evenly be provided with resistance to compression spheroid 6 accordingly, resistance to compression spheroid 6 is steel balls, reinforcing bar in steel ball and the grade beam is welded into a whole back casting cement, thereby make resistance to compression spheroid 6 and grade beam constitute firm integral body, the external diameter of resistance to compression spheroid 6 is less than the internal diameter of the ball at ball recess 4 places, resistance to compression spheroid 6 is embedded in the ball recess 4, this structure can make strip foundation beam and grade beam come temporarily in earthquake can relative motion, be provided with the lubricating layer made from polytetrafluoroethylene (PTFE) 5 between resistance to compression spheroid 6 and ball recess 4, this lubricating layer can make the frictional force when the strip foundation beam is relative with grade beam to slide reduce.Being provided with width in the both sides of strip foundation beam 2 is turning edge of 30cm, and the consistency of thickness of mattress layer in the height that turns edge and the composite foundation makes the organic combination of the utility model and mattress layer.
Preferred structure of the present utility model is that the centre of sphere of resistance to compression spheroid 6 overlaps with the centre of sphere of ball recess 4, and this structure can make after the earthquake, and resistance to compression spheroid 6 and the grade beam 3 above it quickly recover to original position.Strip foundation beam 2 contact with grade beam 3 around be provided with damping rubber block 8, owing between strip foundation beam and the grade beam certain clearance is arranged, damping rubber block around being arranged on that strip foundation beam 2 contacts with grade beam 3 can prevent that tidewater and silt from infiltrating with the sealing of the gap between strip foundation beam and the grade beam.
As shown in Figure 3, the utility model can also be on the basis of Fig. 1 and Fig. 2, two row's roll shafts 1 are set in the gap between strip foundation beam 2 and grade beam 3 at least, adjacent two row's roll shafts are vertical mutually, in strip foundation beam and roll shaft contact position and grade beam and roll shaft contact position be provided with rubber shock-absorbing layer 9.Come to reduce the frictional force of the relative slip with grade beam of strip foundation beam in earthquake so temporarily.
