Abstract
The utility model discloses a combined displacement restrictor for a U-shaped steel sheet and an I-shaped lead rod. The combined displacement restrictor composed of the I-shaped lead rod is embedded at the opening part of the U-shaped steel sheet; the U-shaped steel sheet adopts spring steel; and the I-shaped lead rod is welded with the U-shaped steel sheet. After the combined displacement restrictor deforms under stress, the U-shaped steel sheet provides the elastic restoring force, and the I-shaped lead rod provides the damping force. After the external force is withdrawn, the complete self-centering process of the combined displacement restrictor can be realized through the elastic restoring force of the U-shaped spring steel sheet.
Description
Technical field
The utility model relates to a kind of U shaped steel plate and I type lead rod combination stop that elastic restoring force and damping force can be provided., belong to structures isolation effect control and vibration isolation field, be mainly used in the protection of building foundation earthquake isolating equipments such as house and bridge.
Background technology
The laminated rubber bases shock insulation is a kind of comparatively ripe engineering seismic isolation technology,, reaches the damping effect of " defeating a force with a tenderness " by earthquake isolating equipment.But adopting laminated rubber bases to carry out base isolation also comes with some shortcomings, promptly when the low-frequency component in the experience seismic wave, still there is the possibility that class resonance takes place, at this moment distortion will mainly concentrate on the shock insulation layer, the horizontal movement of neoprene bearing just might surpass its ultimate deformation so, causes unstable phenomenon to take place.
Therefore in order to prevent that unstable phenomenon from taking place, often adopting the steel plate stop to be arranged at the shock insulation layer at present controls, but being the elastic deformation by the steel plate stop, known U shaped steel plate stop provides restoring force, plastic strain provides damping force, its plastic strain is irreclaimable, so stopping means can not be fully from resetting after causing the generation plastic strain.
Summary of the invention
In order to prevent that the neoprene bearing unstable phenomenon from taking place and solving to have the deficiency that U shaped steel plate stop can not reset fully certainly now, the utility model provides a kind of U shaped steel plate and I type lead rod combination stop, this combination stop not only can provide restoring force and damping force, and can be fully from resetting.
The technical scheme that its technical problem that solves the utility model adopts is: this stop comprises steel plate and lead rod, embeds I type lead rod at U shaped steel plate opening and forms the combination stop, and the U shaped steel plate adopts spring steel, and is fixed between I type lead rod and the U shaped steel plate.U shaped steel plate and I type lead rod combination stop and ground are fixed, and U shaped steel plate and I type lead rod combination stop and shock-insulation building shock insulation layer are in same horizontal level, but do not contact with shock insulation layer neoprene bearing.After the neoprene bearing distortion is excessive, U shaped steel plate and the stressed back distortion of I type lead rod combination stop, the U shaped steel plate provides elastic restoring force, and I type lead rod provides damping force.After external force was cancelled, U type steel spring plate was from resetting, and its elastic restoring force promotes I type lead rod and resets.Thereby the combination stop limits the excessive deformation of shock insulation layer simultaneously fully from resetting.
The beneficial effects of the utility model are, are subjected to external force to do the time spent at the combination stop, and elastic restoring force and damping force are provided, and the performance position-limiting action after external force is cancelled, relies on the elastic restoring force of U type steel spring plate to realize that the combination stop is fully from resetting.The combination stop is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an I type lead rod schematic diagram.
Fig. 2 is a U shaped steel plate schematic diagram.
Fig. 3 is a U shaped steel plate I-I schematic cross-section.
Fig. 4 is the utility model U shaped steel plate and I type lead rod combination stop unitary construction figure.
1.I type lead rod among the figure, the 2.U shaped steel plate
The specific embodiment
Among the figure, I type lead rod 1 is cemented in the opening part of U shaped steel plate 2, and employing is welded to connect.After on the U shaped steel plate 2 or lower end was subjected to external force, upper and lower side generation relative deformation drove 1 distortion of I type lead rod.After external force was cancelled, the upper and lower side of U shaped steel plate 2 resetted, and promoted I type lead rod 1 and resetted.
