The damping structure has a simple structure, facilitates the construction and aims to optimize the simple supporting conditions of generator-floor plate girders and upstream/downstream wall column corbels, reduce the vibration of the generator-floor plate girders, prevent vibration damage, decrease noise pollution and guarantee the safety of the structure of hydropower houses and normal operation of hydropower stations. The technical scheme of the utility model is that the damping structure has upstream and downstream wall columns of a hydropower house; outwardly-protruding corbel portions are provided at one side of the upstream and downstream wall columns; and a generator-floor plate girder is erected between the two corbel portions. The damping structure is characterized that a pot-type rubber bearer is disposed between the top surfaces of the corbel portions and the bottom of the generator-floor plate girder. The damping structure of the utility model is suitable for buildings of hydropower houses.
Description
Technical field
The utility model relates to a kind of vibration-proof structure that is used for powerhouse of hydropower station generator floor plate-girder.Be applicable to the powerhouse of hydropower station building.
Background technology
The powerhouse of hydropower station unit vibration can cause the flutter failure and the noise pollution of mill construction, and severe patient can influence the safety and normal operation of powerhouse of hydropower station structure.Can control the resonance and the amplitude of factory building machine pier fan housing structure in the Power Plant Design at present, simultaneously unit machinery carried out ACTIVE CONTROL with electric and magnetic oscillation, but the hydraulic vibration phenomenon have a predictability of being difficult to, often be difficult to carry out ACTIVE CONTROL.The hydraulic vibration frequency is unpredictable and distribution is wider; Thereby generally can not stagger fully with the natural frequency of generator floor floor has the possibility of resonance, and the vibration damping that therefore under the hydraulic vibration situation, how effectively to carry out the generator floor slab and girder just becomes extremely important.
Existing powerhouse of hydropower station is in work progress, and for accelerating construction progress, the general later stage of generator floor slab and girder builds, and the slab and girder freely-supported is on the wall column bracket of upstream and downstream, and freely-supported constraint is more unfavorable but can't avoid to the antivibration of slab and girder.For present most of hydroelectric projects, adopt the asphaltic felt dottle pin between generator floor girder and the support bracket.As time goes on; The asphaltic felt lubrication lost efficacy gradually; When the generator floor vibration of floor that unit vibration causes occurring, plate-girder simply supported end vibration characteristics is a upstream and downstream direction horizontal vibration, and the asphaltic felt dottle pin of inefficacy can be delivered to vibrational energy with the form of frictional force and support the bracket position; Thereby having influence on the main support structure of power plant building---upstream and downstream wall column, serious meeting cause supporting the fatigue failure that bracket is carried out drawing crack seam and roof system steel work.
Summary of the invention
The technical problem that the utility model will solve is: according to the problem of above-mentioned existence; A kind of vibration-proof structure that is used for powerhouse of hydropower station generator floor plate-girder of simple in structure, easy construction is provided; Be intended to optimize generator floor plate-girder and upstream and downstream wall column bracket place freely-supported supporting condition; Reduce the vibration of generator floor slab and girder, weaken flutter failure and reduce noise pollution, ensure the safety of powerhouse of hydropower station structure and the normal operation in power station.
The technical scheme that the utility model adopted is: the vibration-proof structure that is used for powerhouse of hydropower station generator floor plate-girder; Has powerhouse of hydropower station upstream and downstream wall column; Be provided with the bracket portion of outside protrusion in a side of upstream and downstream wall column; Set up the generator floor plate-girder between the two bracket portions, it is characterized in that: be provided with pot rubber bearing between the end face of said bracket portion and the bottom of generator floor plate-girder.
End face in bracket portion is provided with C40 pea gravel concreten layer, and flushes with bracket portion end face; Be embedded with crab-bolt at C40 pea gravel concreten layer position.
Said pot rubber bearing is fixed on C40 pea gravel concreten layer position through crab-bolt, and the top of pot rubber bearing is pre-embedded steel slab fixedly, and this pre-embedded steel slab is double to be done the template at pot rubber bearing position and build with the generator floor plate-girder and be integral.
Be provided with plastic foam plate between said generator floor plate-girder and the upstream and downstream wall column.
The beneficial effect of the utility model is: this shock-damping structure is provided with pot rubber bearing; Make freely-supported support the vertical load that can transmit the generator floor plate-girder; Can effectively discharge the horizontal movement of generator floor plate-girder under unit vibration again, the absorbed oscillation energy reduces the vibration of generator floor slab and girder; Reduced destruction and the noise pollution of Hydropower Plant vibration, thereby ensured the safety of powerhouse of hydropower station structure and the normal operation in power station mill construction.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
As shown in Figure 1, present embodiment is a kind of vibration-proof structure that is used for powerhouse of hydropower station generator floor plate-girder.In powerhouse of hydropower station, be equipped with upstream and downstream wall column 1, the one of which side is provided with the outwards outstanding 1-1 of bracket portion.Freely-supported is placed generator floor plate-girder 2 on the bracket.Between the bottom of the end face of said bracket portion and generator floor plate-girder, be provided with pot rubber bearing 3.The end face of bracket portion is provided with bracket portion end face and flushes C40 pea gravel concreten layer 4; Be embedded with crab-bolt 7 at C40 pea gravel concreten layer position, be used for the fixing of neoprene bearing.Said pot rubber bearing is fixed on the C40 pea gravel concreten layer through crab-bolt, and the top of pot rubber bearing is pre-embedded steel slab 5 fixedly, and this pre-embedded steel slab is double to be done the template at pot rubber bearing position and build with the generator floor plate-girder and be integral.Between generator floor plate-girder and upstream and downstream wall column, be provided with plastic foam plate 6.
During construction, at first accomplish upstream and downstream wall column 1 fist stage concrete and build, this moment, the bracket 1-1 of portion elevation suitably reduced, for pot rubber bearing 3 is installed headspace.The bracket summit portion is reserved C40 pea gravel concreten layer 4 according to the pot rubber bearing pedestal of selecting for use, with the precision that guarantees that pot rubber bearing is installed.The fixing crab-bolt 7 of pre-buried pot rubber bearing when bracket concrete is built after concrete strength meets the demands, is installed pot rubber bearing and at the fixing pre-embedded steel slab 5 of bearing top spot welding, pre-embedded steel slab is used as the formwork for placing at bearing position.The inner end of generator floor plate-girder 2 beams adopts plastic foam plate 6 and upstream and downstream wall column 1 concrete to cut off, and is used to discharge the horizontal movement of freely-supported beam-ends, simultaneously double as beam-ends template.Build generator floor plate-girder second stage concrete at last.
