Description
Technical field
The present invention relates to a kind of building safety protective device, is a kind of earthquake resistance and prevention device for building specifically.
In the known technology, the Chinese utility model patent of patent No. CN200920056384.3 discloses a kind of device with the vibration of opposing secondary wave compressional wave, the pedestal that comprises hollow tube-shape, be provided with the spring with the vibration of buffering P wave in the hollow tube-shape inner chamber of described pedestal, the pile of supported material closely is nested in the pedestal inner chamber and with spring and contacts, and is symmetrical arranged a plurality of groups of springs with the vibration of buffering secondary wave on the pedestal periphery.It buries in underground deeply and supports mutually with housing base ground pile, housing base ground pile is nested in the pedestal inner chamber and by spring to be supported mutually, and present external week arranges the many groups groups of springs with the vibration of buffering secondary wave, it is simple in structure, be skillfully constructed, effectively resisted the shear wave of earthquake generation or the vibration of compressional wave, strengthened the earthquake shock resistance in house, reduce the destruction dynamics of earthquake greatly, thereby the people's lives and property obtains maximum guarantee.
Because the mechanism of buffering secondary wave compressional wave all adopts spring in this device, not only complex structure makes trouble, and rolls owing to shear wave in the earthquake shows as, and the mechanism of buffering secondary wave also adopts spring, and buffering effect is desirable not to the utmost.
Summary of the invention
The purpose of this invention is to provide a kind of earthquake resistance and prevention device that is used for building that the secondary wave compressional wave is satisfactory for result, quakeproof and quake-resistant is effective that cushions.
A kind of earthquake resistance and prevention device for building provided by the invention, it is embedded in below each foundation pile of building and supports each foundation pile respectively, and it comprises:
The lower shell that seal one bottom;
One places the spring assembly in the lower shell;
End closure on one, internal diameter be bigger than lower shell external diameter, be sleeved on the lower shell and by the upper shell of the spring assembly supporting of stretching out the lower shell upper port;
One is fixed on above the upper shell and upper surface forms the supporting base of indent formula arc face, wherein, foundation pile by the spherical universal roller wheel bearing on the indent formula arc face of supporting base.
In above-mentioned, spring assembly is formed by the concentric suit of multilayer compression spring, and this supporting base and upper shell are connected as a single entity by welding, and there is spacing flanging upwards this supporting base marginal portion.
After taking above-mentioned measure, the present invention compared with prior art has following advantage:
Earthquake resistance and prevention device of the present invention buries in underground corresponding with the foundation pile of building respectively, and each foundation pile is supported by the earthquake resistance and prevention device of correspondence respectively.Place spring assembly in the lower shell can effectively cushion the vibration of the compressional wave that earthquake produces by elastic force among the present invention, and foundation pile passes through the spherical universal roller wheel bearing on the indent formula arc face of supporting base, this indent formula arc face provides foundation pile to drive the platform of spherical universal roller swing on the one hand, utilize the lonely degree of indent formula arc face self to the motion of the resistance limits spherical universal roller of spherical universal roller generation on the other hand, can effectively cushion the vibration of the shear wave of earthquake generation, thereby can strengthen the shock resistance of building, reduce the destruction dynamics of earthquake greatly, ensured the people's lives and property effectively.It is simple in structure, makes easily, and quakeproof and quake-resistant is effective, and is easy to utilize.

The specific embodiment
Referring to figs. 1 through Fig. 6, a kind of earthquake resistance and prevention device for building provided by the invention, it is embedded in below each foundation pile 6 of building and supports each foundation pile 6 respectively, and it comprises:
One lower shell 2 is made by steel plate, and the bottom is sealed by steel plate, and the big I of the thickness of slab of steel plate and cylinder internal diameter is decided as required.
One spring assembly 3, place 2 li of lower shells, lower shell 2 upper port are stretched out in the upper end of spring assembly 3, and the height that stretches out also can be decided as required, this spring assembly 3 is formed by multilayer compression spring 8 concentric suits, and the number of plies of compression spring 8 and elastic force size are decided according to actual conditions.
One upper shell 1, made by steel plate, the upper end is sealed by steel plate, internal diameter is bigger than lower shell 2 external diameters, be sleeved on the lower shell 2 and by the spring assembly 3 that stretches out the lower shell upper port and support, the big I of the thickness of slab of steel plate and cylinder internal diameter is decided as required, and the internal diameter size of upper shell 1 is relevant with lower shell 2 external diameter sizes, as long as can guarantee that upper shell 1 can be up and down under pressure.
One is fixed on above the upper shell 1 and upper surface forms the supporting base 4 of indent formula arc face 9, made by steel material, there is spacing flanging 5 upwards these supporting base 4 marginal portions, wherein, foundation pile 6 is bearing on the indent formula arc face 9 of supporting base 4 by spherical universal roller 7, and spherical universal roller 7 shown in Figure 6 has three.As long as indent formula arc face 9 sizes can guarantee have enough positions then can when foundation pile 6 drives 7 swings of spherical universal roller, and the big I of indent formula arc face 9 lonely degree as required and, the resistance that 7 swings of foundation pile 6 drive spherical universal rollers are subjected to when lonely degree is big is just big, otherwise opposite.
The shear wave that the present invention produces during according to earthquake and vertical damaging building, utilization places the spring assembly in the lower shell can effectively cushion the vibration of the compressional wave of earthquake generation, and the indent formula arc face in the supporting base can effectively cushion the vibration of the shear wave of earthquake generation.
