Abstract
The utility model relates to a connecting device special for a laminated rubber shock insulation bearing with a diameter of 500 millimeters and belongs to the technology of shock insulation bearings of buildings. The connecting device comprises a steel sleeve, a reinforcing steel bar and a high strength bolt, wherein the steel sleeve is provided with an internal thread, one end of the reinforcing steel bar is provided with an external thread so that the reinforcing steel bar can be screwed from one end of the steel sleeve, the high strength bolt can be screwed from the other end of the steel sleeve, the minimum specification of the steel sleeve is phi 39*70, the minimum specification of the reinforcing steel bar is 22, the minimum length of the external portion of the reinforcing steel bar is 20 times the diameter of the reinforcing steel bar when the reinforcing steel bar is screwed into the steel sleeve, the minimum strength grade of the high strength bolt is grade 8.8, and the minimum specification of the high strength bolt is M22. After reinforcing steel bars are screwed from one ends of steel sleeves, part of the steel sleeves are poured into the upper structure of the building with openings upward, the others are poured into the lower structure of the building with openings downward, and screws of the high strength bolts are enabled to penetrate through holes at the corresponding positions of flange plates of the shock insulation bearing and screwed into the openings of the steel sleeves. The connecting device special for the laminated rubber shock insulation bearing with the diameter of 500 millimeters is initially provided, and not only the reliable connection is guaranteed, but also the connecting device is economical and reasonable.
Description
Technical field
The utility model belongs to building shock isolating pedestal technology, is specifically related to a kind of device that 500 mm dia laminated rubber damping bearings and building bottom and superstructure are coupled together of being used for.
Background technology
Earthquake is one of serious natural calamity of suffering of the mankind.The harm that how to alleviate earthquake is the key subjects of World Focusing.Building laminated rubber damping bearing technology will be pass by, and traditional " hard anti-" changes " soft anti-" into: the shock isolating pedestal that contains rubber pad is set on the pillar of building foundation, the superstructure and the basis of building separated.Flexible rubber pad in the shock isolating pedestal can be isolated the sharp pounding on ground effectively, thereby reduces fabric structure rocking in earthquake greatly.The structure that has added laminated rubber damping bearing can be become translation slowly by violent swing; Whole superstructure is in elastic state basically; Can absorb and block the input of seismic energy effectively like this to the building superstructure; Thereby reduce the earthquake response of building superstructure, improve the shock resistance of building.
Laminated rubber damping bearing need use linkage and building bottom and superstructure to couple together.For the reliability that can not only guarantee to connect but also most economical rationally, for the laminated rubber damping bearing of different size, its linkage also needs the basis factors such as stress corresponding with it to carry out special specifications design.
The bibliographical information that does not also have at present the special-purpose linkage of 500 mm dias laminated rubber damping bearing for building.
The utility model content
The purpose of the utility model provides a kind of linkage that is exclusively used in 500 mm dia laminated rubber damping bearings, not only guaranteeing to connect reliably but also most economical reasonable.
The structure of the utility model: include a steel bushing with internal thread; Thereby a radicle has the reinforcing bar that external screw thread can be screwed into from steel bushing one end; The high-strength bolt that can be screwed into the steel bushing other end; The steel bushing minimum gauge is Φ 39 * 70; The reinforcing bar minimum gauge is
22; It is 20 times of bar diameter that reinforcing bar is screwed into outside minimum length behind the steel bushing, and high-strength bolt minimum intensity grade is 8.8 grades, minimum gauge M22.And the linkage that is used for 500 mm dia laminated rubber damping bearings is most economical, reliable technique scheme is: the steel bushing specification is Φ 39 * 70; Bar gauge is
22; Reinforcing bar is screwed into that outside length is 20 times (promptly 440 millimeters) of bar diameter behind the steel bushing; The high-strength bolt strength grade is 8.8 grades, specification M22.
The method for using of the utility model: reinforcing bar is after steel bushing one end is screwed into, and steel bushing is uncovered up to be cast in the building substructure, and steel bushing is cast in the building superstructure towards lower open mouth.Shock isolating pedestal is put between building superstructure and the substructure; Let the screw rod of high-strength bolt pass the through hole on the shock isolating pedestal flange relevant position and be screwed into the uncovered of steel bushing, thereby let the lower flange of shock isolating pedestal and upper flange plate be anchored on respectively on building substructure and the superstructure.
The utility model both can be used for the natural rubber shock isolating pedestal, also can be used for the lead-rubber shock isolating pedestal.
The utility model beneficial effect: provide a kind of first and be exclusively used in the linkage of 500 mm dia laminated rubber damping bearings, can guarantee to connect reliably most economical again rationally.
Description of drawings
Fig. 1 is the main TV structure sketch map of embodiment.
Fig. 2 looks cross-sectional view for the master of embodiment.
The master of relevant structure looked generalized section when Fig. 3 installed and used for embodiment.
The specific embodiment
Embodiment: see Fig. 1～3.Steel bushing 1 has internal thread, and specification is Φ 39 * 70.Reinforcing bar 2 specifications are
22; One end has external screw thread, and it is 500 millimeters that reinforcing bar 2 is screwed into outside, steel bushing 1 back length.High-strength bolt 3 strength grades are 8.8 grades of pressure-bearing types, specification M22.
When installing and using, reinforcing bar 2 is after steel bushing 1 one ends are screwed into, and steel bushing 1 is uncovered up to be cast in the building substructure 4, and steel bushing 1 is cast in the building superstructure 5 towards lower open mouth.Shock isolating pedestal 6 is put between building superstructure 5 and the substructure 4; Let the screw rod of high-strength bolt 3 pass the through hole on the flange relevant position of shock isolating pedestal 6 and be screwed into the uncovered of steel bushing 1, thereby let lower flange 7 and the upper flange plate 8 of shock isolating pedestal 6 be anchored on respectively on building substructure 4 and the superstructure 5.The pattern of shock isolating pedestal 6 shock insulation pads is 1-LNR500 or 1-LRB500.
