Abstract
The utility model provides a connecting device special for a laminated rubber seismic isolation support with a diameter of 400 millimeters, belonging to the technology of seismic isolation supports for buildings. The connecting device comprises a steel sleeve cylinder provided with internal screw threads, a steel bar with the end portion with external screw threads so as to be screwed in from one end of the steel sleeve cylinder, a high-strength bolt capable of screwed in the other end of the steel sleeve cylinder, the minimal specification of the steel sleeve cylinder is phi 38*65, the minimal specification of the steel bar is 20, the external minimal length of the steel bar after being screwed in the steel sleeve cylinder is twenty times that of the diameter of the steel bar, the minimal strength grade of the high-strength bolt is grade 8.8, and the minimal specification is M20. After the steel bar is screwed in from one end of the steel sleeve cylinder, the steel sleeve cylinder is respectively opened upwards and downwards and cast in the upper and lower structures of the building, and a screw of the high-strength bolt goes through a through hole at a corresponding position of a seismic isolation support flange, and is screwed in the opening of the steel sleeve cylinder. The connecting device special for a laminated rubber seismic isolation support with a diameter of 400 millimeters is provided for the first time, and the connecting device is advantaged by guarantee of reliable connection and economy and reasonableness.
Description
Technical field
The utility model belongs to building shock isolating pedestal technology, is specifically related to a kind of device that 400 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 400 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 400 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 38 * 65; The reinforcing bar minimum gauge is
20; 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 M20.And the linkage that is used for 400 mm dia laminated rubber damping bearings is most economical, reliable technique scheme is: the steel bushing specification is Φ 38 * 65; Bar gauge is
20; Reinforcing bar is screwed into that outside length is 20 times (promptly 400 millimeters) of bar diameter behind the steel bushing; The high-strength bolt strength grade is 8.8 grades, specification M20.
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 38 * 65.Reinforcing bar 2 specifications are
20; One end has external screw thread, and it is 400 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 M20.
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-LNR400 or 1-LRB400.
