Description
Technical field
The utility model relates to a kind of shock insulation apparatus technical field, especially relates to a kind of tin core rubber earthquake isolation support.
Background technology
Rubber earthquake isolation support is the main earthquake isolating equipment in shock insulation engineering, wherein be most widely used with lead core rubber support, but due to the pollution of lead to environment and the infringement to health, and the lead for retractable pencil life-span is short, plastic deformation ability is poor, angle for environmental protection and safety is considered, lead core rubber support must need to reform, to adapt to the demand of society and technological progress.
Utility model content
For above-mentioned defect and the problem of prior art, technical problem to be solved in the utility model is to provide a kind of tin core rubber earthquake isolation support, and its structure is simple, reasonable in design and result of use is good.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of tin core rubber earthquake isolation support, comprise two pieces of junction plates, tin core and middle skeleton, junction plate arranges connecting hole, described middle skeleton comprises block rubber, shrouding and at least one block of steel sheet, middle skeleton is fixedly installed between junction plate, described steel sheet center has through hole, and described block rubber is arranged between upper junction plate and lower connecting plate, and steel sheet is arranged on the inside of block rubber.
In technique scheme, described steel sheet is evenly arranged on the inside of block rubber.
In technique scheme, described block rubber arranges groove, and described shrouding is installed in the groove of block rubber.
In technique scheme, described junction plate is connected with the shrouding of middle skeleton.
In technique scheme, described junction plate is rectangle steel plate.
In technique scheme, described connecting hole is arranged on four angles of junction plate.
In technique scheme, described middle skeleton through hole inner surface is irregular.
The utility model structure is simple, reasonable in design and result of use is good; tin core is adopted to decrease the pollution of material to environment; protection health; simultaneously because tin possesses good plastic deformation ability; reverse cyclic loadings performance, normal temperature recrystallization etc., can in earthquake earthquake energy repeatedly; safe and reliable, low cost of manufacture.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the A-A ' sectional view of Fig. 1.
Wherein: 1, upper junction plate; 2, lower connecting plate; 3, tin core; 4, steel sheet; 5, block rubber; 6, upper sealing plate; 7, lower shrouding; 8-1, the first bolt; 8-2, the second bolt; 9, shock-damping structure part connecting hole is treated; 10, base surface connecting hole; 11, irregular.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
According to Fig. 1, Fig. 2, as a kind of tin core rubber earthquake isolation support shown in embodiment, comprise upper junction plate 1, lower connecting plate 2, tin core 3 and middle skeleton, junction plate is rectangle steel plate, four angles of junction plate arrange connecting hole respectively, described middle skeleton comprises steel sheet 4, upper sealing plate 6 and lower shrouding 7, described steel sheet center has through hole, described block rubber is arranged between upper junction plate and lower connecting plate, the quantity of described steel sheet 4 is polylith, and polylith steel sheet 4 is evenly arranged on the inside of block rubber 5, and embodiment steel sheet quantity is 5-10 block.
Middle skeleton is fixedly installed between upper junction plate 1 and lower connecting plate 2, and be irregular inside middle skeleton through hole, tin core 3 is metal bar, during tin core is pressed into after middle skeleton heat cure is shaping in skeleton through hole.Middle skeleton through hole inner surface is irregular face 11, irregular is the male and fomale(M&F) of the degree of depth at 1-5mm, tin core press-in after can not with middle skeleton through hole inner surface compact siro spinning technology, when bearing damping, such a construction reduces tin core to contact with middle skeleton through hole inner surface, extend application life of the present utility model.
Block rubber 5 is arranged between upper junction plate 1 and lower connecting plate 2, and block rubber arranges groove, and upper sealing plate 6 blocks and lower shrouding 7 is installed in the groove of block rubber 5 respectively.
Upper sealing plate 6 is fixedly connected with upper junction plate 1 by the first bolt 8-1, and described lower shrouding 7 is fixedly connected with lower connecting plate 2 by the second bolt 8-2
When the utility model uses, treat that the quantity of shock-damping structure part connecting hole 9 and base surface connecting hole 10 is four, treat that symmetrical the alignment with the connecting hole on four angles being arranged on upper junction plate 1 of shock-damping structure part connecting hole 9 is bolted, base surface connecting hole 10 is bolted after being symmetricly set on the connection alignment on four angles of lower connecting plate 2.
Lead core rubber support identical with same median pore diameter for the utility model is carried out compression-shear test, result shows: the yield force of tin core is obviously greater than lead for retractable pencil, actual measurement is about 1.68 times, post-yield stiffness does not change because of the difference of mandrel material, and therefore tin core neoprene bearing is more excellent than lead core rubber support effect.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
