Description

A kind of steel building cylinder antidetonation buffering pedestal
Technical field
The present invention relates to a kind of steel building cylinder antidetonations to buffer pedestal, belongs to building field.
Background technique
The structure that steel construction is made of steel material is one of main building construction types.Structure is mainly by fashioned iron With the components composition such as joist steel, steel column, steel truss made of steel plate etc., and using silanization, pure manganese phosphatization, washing drying, zinc-plated Equal derusting rust-proofings technique.Weld seam, bolt or rivet interlacement are generallyd use between each component or component.Because its self weight is lighter, and apply Work is easy, is widely used in the fields such as large-sized workshop, venue.The main support member of steel building is steel structural upright column, in order to Enhance the stability of strutting system of steel structural upright column lower end, ground can be set in the lower end of steel structural upright column.Existing steel structural upright column Ground is usually with ground foundation pit using being rigidly connected, and such connection type antidetonation cushion performance is poor, when big in building When type equipment is run, the vibration of equipment and pressure are transferred to support cylinder by floor, and support cylinder will shake after being shaken It is dynamic to be transferred to pedestal and make seat vibration foundation pit and surrounding ground based substrate, so that foundation pit and surrounding ground base Matter is loose, and cylinder and pedestal is caused to sink.
Summary of the invention
Technical solution of the present invention is for existing in the prior art: " existing steel structural upright column ground is usually and ground For face foundation pit using rigid connection, such connection type antidetonation cushion performance is poor, when the large scale equipment operation in building, if Standby vibration and pressure is transferred to support cylinder by floor, and support cylinder transmits these vibrations to pedestal after being shaken can make It obtains seat vibration foundation pit and surrounding ground based substrate and causes cylinder so that foundation pit and surrounding ground based substrate are loose And pedestal sinks " deficiency, a kind of steel building cylinder antidetonation buffering pedestal is provided.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of steel building cylinder antidetonation buffering Pedestal, including steel structural upright column and foundation pit, steel structural upright column are I-steel;It is living that the lower end of the steel structural upright column is provided with column Moving base, the lower end of steel structural upright column are socketed in column movable base, are filled between steel structural upright column and column movable base There is concrete;It is provided with column fixed pedestal in the foundation pit, concrete is filled between column fixed pedestal and foundation pit;It is described Column movable base is socketed in column fixed pedestal and is slidably connected with column fixed pedestal, and column movable base and column are solid Determine to be provided with several cushioning supportive components between pedestal;The steel structural upright column is plugged in the setting of one end in column movable base Have column fixing piece steel structural upright column being fixed in column movable base;It is connected on the outer surface of the column fixed pedestal Have pedestal fixation kit column fixed pedestal being fixed in the concrete that foundation pit is filled.
In the technical solution of the application, the column activity of concrete is poured by being provided in the lower part of steel structural upright column Pedestal, and fixed steel structural upright column and column movable base by column fixing piece, column fixed pedestal is set to foundation pit It is interior and fixed by pedestal fixation kit.When generation column is shaken influence, fixed by the way that movable base is fixed with column It is fixed relatively sliding with column fixed pedestal that the activity direction of steel structural upright column is limited to movable base by being slidably socketed of pedestal Dynamic direction reduces influence of the vibration for column fixed pedestal by the buffering of cushioning supportive component, and then reduces vibrational energy Vibration is transferred to the soil around foundation pit and foundation pit by column fixed pedestal, prevents the loosing soil around foundation pit and foundation pit To cause pedestal to sink.
Optimization, above-mentioned steel building cylinder antidetonation buffers pedestal, and the column movable base includes a sliding sleeve Cylinder, sliding sleeve upper end opening;The column fixed pedestal includes a fixes sleeve, fixes sleeve upper end opening;The cunning Moving sleeve setting coaxial with fixes sleeve, the lower end of sliding sleeve are socketed in fixes sleeve, the outer wall of sliding sleeve and fixation The inner wall sliding contact of sleeve;The lower section of the steel structural upright column is socketed in sliding sleeve and by column fixing piece and sliding Concrete in sleeve is fixed.
In the application, sliding sleeve is socketed in fixes sleeve, passes through the opposite sliding of sliding sleeve and fixes sleeve The moving direction of steel structural upright column is limited, fixes sleeve is fixed in the concrete in foundation pit, passes through consolidating for pedestal fixation kit It can prevent fixes sleeve from rolling, so that steel structural upright column, sliding sleeve will not roll, and steel construction is vertical surely Column is pushed due to bearing the weight of whole building so that sliding sleeve is pressed in fixes sleeve, does not fall out fixes sleeve.
Optimization, above-mentioned steel building cylinder antidetonation buffers pedestal, and the cushioning supportive component includes interior barrel, outside Cylinder, compressed spring;The axis of the axis of the interior barrel, the axis of outer barrel and fixes sleeve is arranged in parallel;Interior barrel is fixed In on the outer bottom end face of sliding sleeve, outer barrel is fixedly installed on the inner bottom end face of fixes sleeve, and interior barrel is socketed on It is slidably connected in outer barrel and with outer barrel;Length is greater than the length of interior barrel under the compressed spring free state, compresses bullet One end of spring be socketed in interior barrel and with internal tube inner surface compressive contact, the other end of compressed spring is socketed in outer barrel And with external tube inner surface compressive contact.
In the technical solution of the application, when vibration is transferred to pedestal by column, sliding sleeve is sliding in fixes sleeve Dynamic, interior barrel is slided in outer barrel, and compressed spring spring restores to absorb vibration energy by flexible deformation and elasticity, is reduced solid Determine the vibration of sleeve, to reduce the vibration of pedestal, the soil around pedestal influences to reduce due to being shaken, and will not occur It spends loose and pedestal is caused to settle.Interior barrel slides the compression direction for playing limitation compressed spring in outer barrel and elasticity is extensive Compound to effect, and limit the position of compressed spring, prevent it from shifting.
