Description
Technical field
The utility model belongs to the building structure field of components, relates in particular to the pot rubber bearing of a kind of high-performance, low cost of manufacture.
Background technology
Bridge pad is the important structure parts that connect bridge superstructure and substructure, and it can pass to bridge substructure reliably with the counter-force and the distortion (displacement and corner) of bridge superstructure.
Bridge pad has various ways, and pot rubber bearing is wherein a kind of.Existing pot rubber bearing kind is a lot of on the market, but the applied principle of its product design all is the same, a rubber tile is placed among the steel basin of pot rubber bearing exactly, utilize the concentrated relatively counter-force of damping characteristic slowly-releasing of elastomeric material, finish the transmission of power by rubber tile support part up and down reliably.
Pot rubber bearing is made with metal material and organic material, and main weight and manufacturing cost concentrate on the metal material part.It is the cast steel blank that casts out each assembly of pot rubber bearing with the method for casting that manufacturing pot rubber bearing metal parts part has only two kinds of passing methods, first method at present, finally finishes the manufacturing of each metal assembly again by machine; Second method is to be assembly blank material with hot rolling system steel plate, adopts melting process to weld out the steel plate of anchor hole position, finally finishes the manufacturing of each metal assembly again by machine.Owing to be subjected to the restriction of manufacturing cost and equipment, at present other is not arranged as yet, can both improve the quality of pot rubber bearing, can make method cheap for manufacturing cost again.
Now, road has been an inevitable outcome by heavy-duty vehicle and hot-short use.In addition, there are a lot of high-grade road sections also will build again at cold district.Along with the requirement to road equipment functional performance condition improves, if continue to adopt traditional pot rubber bearing obviously to have problems.Adopt above-mentioned first method to make pot rubber bearing and have following shortcoming: one, because the cryophylactic poor-performing of cast steel material, traditional rubber pot bearing is not suitable for using at cold district; Its two owing to be easy to generate inherent defects such as field trash and cast steel body crystal grain is thick in the steel-casting, pot rubber bearing is difficult to carry out control of product quality; They are three years old, since the physical property of cast steel material than forged or the physical property of the similar steel of rolling mistake far short of what is expected, use cast steel material to make the design strength requirement that pot rubber bearing is difficult to guarantee product, therefore neoprene bearing probability of damage height in actual use, thus accident risk brought; Its four, adopt the cast steel blank to make pot rubber bearing, spillage of material is up to about 30% in mach process, waste of material is many, workload is too big.Also there is following shortcoming and take above-mentioned second method to make pot rubber bearing: one, spillage of material is adopted more than the cast steel blank in mach process, waste of material is more, workload is bigger, and the design size of bearing is big more, and the spillage of material ratio in the process will be high more; They are two years old, make the pot rubber bearing of same size, second method is high more a lot of than the manufacturing cost of first method, in order to obtain low manufacturing cost, often can only adopt and reduce rubber bearing plate loaded area, thereby reduce the overall weight of pot rubber bearing, exchange the way of hanging down manufacturing cost for the way of saving the Master Cost expenditure, so way has still reduced the supporting capacity of pot rubber bearing in essence; They are three years old, second kind of manufacture method must be used the molten solder technology of macro-energy output electric energy, come the steel plate of weld anchor keyhole position, and the inside and outside temperature in molten bath substantially exceeds the Summoning phase transition temperature during welding of this technology, the result of its temperature action causes the distortion of the thick again or workpiece parent of the steel crystal grain of weld bond periphery often, unfavorablely also will increase manufacturing cost for eliminating this.
