Description
Technical field
The utility model relates to a kind of damping device for silo, belongs to cushion technique field.
Background technology
Silo, is the vertical vessel storing bulk solids, is widely used in industrial and agricultural production and accumulating department.The flat shape of silo has square, rectangle, polygon and circle etc., can save land for warehouses, is conducive to carrying out loading and unloading mechanization and automation, reduces labour intensity, raises labour productivity, and the loss of minimizing material and dust are to the pollution of environment.Silo all can be given a shock with during earthquake reinforced.Have when silo feeds in raw material and load fast, that load is large and uneven feature.Thus all should be specifically noted that when soil investigation, soil exploration and basic engineering, and using the uniformity of initial stage controlled loading speed and loading, to avoid accident.The special Lance Kang Na reserves of Canada are the silo of 27000 tons, and because prospecting carelessness and first fuel loading are too fast, diel tilts to reach 26 ° 53 ', just reuses after alignment.Silo institute storing material generally all can be heavier, and be easy under geological process because the center of gravity of silo is higher and form the top-heavy form of structure being unfavorable for antidetonation, thus more easily being destroyed, the ratio that in actual conditions, this kind of silo caves in is also larger.
All damping device is not configured, to the long-term adverse effect of lower support structure when substantially not considering that silo feeds in raw material in existing Design of Silo.And for geological process, the mode increasing the lower support rigidity of structure that adopts, but supporting construction cross section can be caused excessive, or the shortcoming of narrow space under silo more.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of damping device for silo.
The purpose of this utility model is achieved through the following technical solutions:
For a damping device for silo, described silo comprises silo body and is positioned at the supporting construction below described silo body, and described damping device is located between described silo body and supporting construction, and described damping device comprises:
Upper junction steel plate, connects described silo body;
Lower junction steel plate, connects described supporting construction;
Laminated rubber bearing, is clamped between described upper junction steel plate and lower junction steel plate.
Further, described upper junction steel plate is by being welded to connect described silo body.
Further, described lower junction steel plate connects the built-in fitting on described supporting construction.
Further, described lower junction steel plate is by being welded to connect the built-in fitting on described supporting construction.
Further, described laminated rubber bearing comprises laminated rubber, and is disposed on the steel sheet in described laminated rubber.
Further, described laminated rubber bearing by steel sheet and Thin rubber plate be superimposed sulfuration bond form.
The beneficial effects of the utility model are:
The utility model by increasing damping device between silo body and its supporting construction, has the effect of vertical damping, can greatly reduce impact when silo feeds in raw material to the adverse effect of supporting construction, improve the application life of silo; Also there is level to cushioning effect simultaneously, the geological process being delivered to upper silo from ground can be greatly reduced, improve the form of structure being unfavorable for antidetonation that silo is intrinsic.Add the safety of silo and reduce the construction cost of silo.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
For a damping device for silo, the supporting construction 5 that described silo comprises silo body 6 and is positioned at below described silo body, described damping device 4 is located at described damping device 4 between described silo body 6 and supporting construction 5 and is comprised:
Upper junction steel plate 1, connects described silo body 6;
Lower junction steel plate 2, connects described supporting construction 5;
Laminated rubber bearing 3, is clamped between described upper junction steel plate 1 and lower junction steel plate 2.
Described upper junction steel plate 1 is by being welded to connect described silo body 6.
Described lower junction steel plate 2 is by being welded to connect the built-in fitting on described supporting construction 5.
Described laminated rubber bearing 3 comprises laminated rubber, and is disposed on the steel sheet in described laminated rubber, or described laminated rubber bearing 3 by steel sheet and Thin rubber plate be superimposed sulfuration bond form.
Damping device described in the utility model adopts the form of laminated shock isolation support, is the extraordinary flexible supporting device of a kind of practicality.The laminated rubber bearing selected of the present embodiment is superimposed by steel sheet and Thin rubber plate and forms through high temperature vulcanized bonding.The rubber adopted is natural rubber and neoprene.Neoprene is except freeze proof and elastic performance, other performances (oil resistant, corrosion-resistant, anti-aging and damping etc.) are all better than natural rubber, it is a kind of very ripe, special material of being applied to vibration isolation, be widely used in the base isolation technology of bridge, large-span space structure and civilian construction, but be also never applied to silo structure.
Damping device of the present utility model has very high vertical location and very little compressive strain, can guarantee the safety of silo; Described damping device also has larger horizontal deformation, and shear strain can reach 100% and not destroy; Described damping device has elastic reset characteristic, and building can be made after earthquake automatically to set back.Described damping device simple structure, cheap, there is certain displacement function.When earthquake, upper and lower part structure can have certain relative displacement ability, the cycle of structure is increased by shear strain, stagger predominant period of seismic wave, therefore there is shock insulation function, the vertical rigidity simultaneously overcoming rubber is little, the shortcoming of horizontal loads stability inferior difference.
Owing to adding steel sandwich1 in rubber layer, and rubber layer and sandwich clad steel tight bond, when neoprene bearing bears vertical load, the lateral deformation of rubber tile suffers restraints, and makes neoprene bearing have very large vertical bearing capacity and vertical rigidity.Because steel sheet does not affect the shear strain of rubber tile, make rubber tile to the motion of any horizontal direction all in flexible constraint.When damping device load level load, the relative sidesway of its rubber layer greatly reduces, and makes described damping device can reach very large overall sidesway and unlikely unstability, and keeps less horizontal rigidity (being only the 1/500-1/1500 of vertical rigidity).And, due to sandwich clad steel and rubber layer tight bond, rubber layer can also bear certain pulling force under Vertical Earthquake Loads, makes this device become the desirable damping device that a kind of vertical bearing capacity is very big, horizontal rigidity is less, horizontal comparison admissible value can bear very greatly, again Vertical Earthquake Loads.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
