Abstract
The utility model relates to a bearing, in particular to a rubber bearing with lead core. The structure of the rubber bearing with lead core is characterized in that square rubber sheets and thin steel plates are alternatively arranged between two steel plates and bonded by vulcanization; four corners are chamfered into fillets, the periphery and the protection rubber are vulcanized into a whole; and the lead core is compactly pressed in the reserved hole of the square rubber bearing. The rubber bearing is convenient for manufacturing and machining, without need of machining the steel plate and the rubber sheet into round, thus saving a large amount of procedures; almost no leftover material is produced, material is saved, therefore, the rubber bearing has low manufacture cost; and the four corners are chamfered into fillets, thus reducing stress concentration.
Description
Technical field
The utility model relates to a kind of shock insulation device, specifically is a kind of rubber lead for retractable pencil shock isolating pedestal, can reduce the destruction of vibrating load such as earthquake to civil engineering structure, the protection engineering structures.
Background technology
At present, generally all adopt round rubber lead for retractable pencil shock isolating pedestal in the civil engineering structure of employing seismic isolation technology, but this need be processed into circle to steel plate, sheet rubber in advance, produces a lot of leftover pieces and causes waste.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber lead for retractable pencil shock isolating pedestal, and this bearing can change civil engineering structure mechanical characteristic and damping characteristic, alleviates seismic forces to its destruction.
The rubber lead for retractable pencil shock isolating pedestal that the utility model provides; it comprises support body and protection glue-line; the protection glue-line is arranged on the side surface of described support body; described support body is by alternately placing sheet rubber between two blocks of shroudings and steel sheet constitutes; it is characterized in that: described support body is square; two blocks of shroudings all fall into fillet for four jiaos with each steel-sheet, and the center of described support body is provided with circular preformed hole, is filled with lead for retractable pencil in the preformed hole.
The rubber lead for retractable pencil shock isolating pedestal that the utility model provides is made easy to process, does not need steel plate, sheet rubber are processed into circle, saves a lot of operations; Almost do not have leftover pieces, economize with material, cost is low; And fall into fillet to four jiaos, reduce stress and concentrate.
Description of drawings
Fig. 1 is the utility model rubber lead for retractable pencil shock isolating pedestal vertical view.
Fig. 2 is the utility model rubber lead for retractable pencil shock isolating pedestal A-A sectional drawing.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the structure of rubber lead for retractable pencil shock isolating pedestal is: support body is square, and by alternately placing sheet rubber 2 between two blocks of shroudings 1 and steel sheet 3 constitutes, four jiaos of shrouding 1 and steel sheet 3 are all fallen into fillet.The center of support body is provided with circular preformed hole, at the side surface of support body one circle protection glue-line 5 is set, and by sulfuration with each parts bonding together, closely is pressed into lead for retractable pencil 4 in preformed hole again.
During enforcement; the center of shrouding 1 (steel plate), sheet rubber 2 and steel sheet 3 all has preformed hole in advance; four jiaos of shrouding 1 and steel sheet 3 are all fallen into fillet; be positioned over shrouding 1 and sheet rubber 2 and steel sheet 3 in the mould on request; put into protection glue-line 5 again in their side, put into vulcanizer then and be sulfided into one.After from mould, taking out at last, lead for retractable pencil 4 closely is pressed in each preformed hole.
