Description
Technical Field
The invention relates to an anti-rollover metal vibration reduction support in the technical field of viaducts of railways and highways.
Background
The construction of highways and urban overpasses consumes huge cost, and particularly the construction cost of the bridge piers of the viaduct is high. In order to save the construction cost under the conditions of being limited by the construction geographical position and saving land use, according to the requirements of construction units, a plurality of design units design more piers into a support type of a single pier and single support; the combined support combined with the support of the full-floating movable supports on a plurality of piers is supported by the fixed supports on one pier, so that the matching position of the joint can be automatically adjusted when the cover beam (the transverse beam for transversely supporting the beam body) and the beam body (the longitudinal beam body) expand with heat and contract with cold. The total load of the trucks continuously running on the viaduct exceeds the designed load, the exceeding of the designed load is often the main reason of torsion and overturning of the viaduct, and the torsion and overturning cause a plurality of rollover accidents of the viaduct.
When the girder body of the viaduct with the plurality of piers and the plurality of supporting beam bodies bears the continuous load-carrying vehicle passing through the single side, the stability of the supporting beam body is the best, but the construction cost is the highest. The construction cost of the viaduct with the single-pier single-support supporting beam body is the lowest, but when the viaduct with the single-pier single-support supporting beam body bears a continuous single-side passing truck, the stability of the supporting beam body is the worst, and the side turning of the viaduct is easily caused. In order to reduce the construction cost, the construction unit often requires the design unit to design most of the multiple piers as single piers.
The pier supported by the single pier is provided with two types, namely a side column pier and a middle pier, the side column pier is provided with a capping beam, and the middle pier is mostly not provided with the capping beam; fixed supports are adopted between the capping beams and the beam bodies of the viaducts of the side column piers for supporting, and full-floating supports are adopted between the beam bodies of the viaducts of the middle piers without capping beams and the upper ends of the piers and between the capping beams of the viaducts of the middle piers without capping beams and the upper ends of the piers for supporting.
The fixed support is characterized in that the support, the cover beam and the support cushion stone are fixed together through anchor bolts preset in the cover beam and the support cushion stone, and the support and the beam body are fixed together through a beam bottom embedded steel plate preset in the beam body through the anchor bolts, so that the support bears the weight of the beam body above and passing vehicles; the full-floating support is characterized in that a support is placed on a support base stone for fixing a support base lower steel plate on a cover beam through an anchor bolt or placed on a support base stone for fixing the support base lower steel plate on the upper end of a pier through the anchor bolt, a beam bottom embedded steel plate preset in a beam body is used for fixing a support base upper steel plate and the beam body together through the anchor bolt, and the support base upper steel plate is pressed on the full-floating support to bear the weight of the beam body and passing vehicles.
At present, a plate type rubber support and a basin type rubber support are mainly used for a viaduct of a highway;
the pot type rubber support is divided into a fixed support and a movable support, and the movable support is divided into a multi-directional movable support and a longitudinal movable support; the movable basin type rubber support comprises an upper support plate, a polytetrafluoroethylene plate, a pressure-bearing rubber block, a rubber sealing ring, a middle support plate, a steel clamping ring, a lower support plate and an upper support connecting plate and a lower support connecting plate; the fixed support can be formed by combining the upper support plate structure and the middle support plate structure or by utilizing the upper support connecting plate and the lower support connecting plate. While
The fixed support and the full-floating movable support are adopted without carrying outLimiting and fixingThe integral seat body connected up and down or the upper and lower combined integral seat body without limit fixing is adopted, and a locking device which is locked and does not deviate towards the two sides of the beam body and a locking device which is locked between the upper support plate and the lower support plate are not arranged. And then the side turning of the beam body of the viaduct is easy to happen when the left and right beam bodies of the viaduct bear uneven load.
The plate-type rubber support is rectangular and circular and is not divided into a fixed support and a movable support; a thin steel plate or a steel wire mesh is used as a stiffening layer to improve the vertical bearing capacity of the support; rotation is achieved by uneven elastic compression and horizontal displacement is achieved by shear deformation. The lower steel plate of the support is fixed on the bent cap and the support cushion by adopting the anchor bolt or the support is placed on the support cushion which is fixed on the upper end of the pier by the anchor bolt, and the upper steel plate of the support is fixed with the beam body by the beam bottom embedded steel plate which is preset in the beam body by the anchor bolt, so that the upper steel plate of the support is pressed on the full-floating support to bear the weight of the beam body and the passing vehicle. While
The plate type rubber support is placed on an upper steel plate of the support and a lower steel plate of the support, and is not provided with a locking device for locking the steel plate and the lower steel plate of the support, and the locking device for locking the steel plate and the lower steel plate of the support is not arranged on two sides of a beam body. And then the side turning of the viaduct is easy to happen when the left and right beam bodies of the viaduct bear uneven load.
In addition, when the traditional support is selected, the safety reserve of the support does not need to be worryed too much, for example, the maximum reaction force of the support is 4100, the minimum reaction force is 3700, and then the support with the bearing capacity of 4000 is selected, because the allowable range of the support reaction force of the 4000 support is 3200-4200, and the support with the bearing capacity of 5000 cannot be selected from the viewpoint of safer consideration. The 5000 seat is not preferred because the lowest suitable load bearing is 4000, and the minimum reaction 3700 is already below this value.
In addition, the frequent safety accidents of side turning of the beam body of the viaduct cause huge economic loss and property damage; the remedial measures taken are: the number of the transverse piers of the viaduct is increased, and the construction cost for remedying the increased piers is extremely high.
Therefore, as seen from the above background art, the conventional support used for the viaduct has only the function and capability of supporting the load of the beam body, and has no function and capability of preventing the side turn at all.
At present, in the prior art, there is also a bridge anti-overturning support and a construction method thereof with patent number CN2015105183408, but the whole support is fixedly connected with a beam body and a cover beam through a screw, so that although the side turning of the beam body of the viaduct can be prevented, the beam body cannot slide back and forth on the support and cannot adapt to the extension and contraction caused by thermal expansion and cold contraction of the beam body, so that the beam body easily inclines or inclines a pier, and the support cannot be practically applied to the construction of the viaduct. There is also a bridge anti-overturning support with the patent number CN2016104866163, which prevents the overturning of the beam body during earthquake, and the three plates are in contact fit through the inserting plates which are arranged in a cross way, and the inserting plates and the three plates are in cylindrical roller fit, so as to improve the sensitivity of the earthquake-proof efficiency; the adjacent jack boards are matched through the brake pads arranged at intervals, and when an earthquake occurs, the amplitude of the horizontal force of the earthquake is decomposed into high-frequency low-amplitude vibration, so that the earthquake resistance is improved; but the three plates are not limited to be incapable of moving up and down and transversely moving the beam body, and the function of preventing the side turning of the beam body of the viaduct is not realized. A curved beam bridge anti-overturning support with the patent number of CN2017102968862 is also arranged, but a connecting rod is hinged and fixed in the middle of one side of the upper end face of the rotating sleeve, two connecting rods 8 are hinged in the middle of the two support main bodies, and the connecting rods 8 which are hinged and fixed on the rotating sleeves of the two support main bodies are respectively arranged in front of and behind the two rotating sleeves; the support main body bears the downward pressure of the beam body under the action of unbalance loading, so that the side rotary bearing drives the rotary sleeve to move downwards together, the downward-pressed rotary sleeve enables the tiger teeth to move upwards in the sliding track of the inner wall of the sleeve, the side rotary sleeve 3 rotates around the rotary bearing under the action of the counter force of the tiger teeth 5 acting on the sliding track 9, the upper connecting rod 8 of the rotary sleeve 3 is driven to rotate, the force is transmitted to the rotary sleeve of the support on the other side through the two hinged connecting rods, the rotary sleeve on the other side rotates spirally upwards around the side rotary bearing 4, and the rotary force enables the rotary pump to generate downward pulling force on the side beam body and resist the torque generated by unbalance loading; the device is not limited by itself, the fixed support cannot move up and down, and the function of preventing the side turning of the beam body of the viaduct is not realized. The anti-overturning device is also provided with a single-column pier bridge anti-overturning device based on the self-balancing structure with the patent number of CN2017202109525, but the anti-overturning device transfers, converts and changes the direction of force through a force transfer rod piece, a pulley and a powerful steel wire rope, and transfers the offset load force originally acting on one side to the other side, so that the two sides of the bridge are stressed in a balanced manner; the bridge cannot be locked and cannot move transversely and vertically, and the function of preventing the side turning of the bridge of the viaduct is not realized.
In order to eliminate technical defects in the prior art and potential safety hazards caused by a viaduct supported by a single independent pier support, a rollover-preventing metal vibration reduction support capable of preventing the viaduct supported by the single independent pier from rollover to the greatest extent is designed through years of research and practice.

After the anti-rollover metal vibration reduction support is fixed between a beam body of a viaduct and a support cushion stone at the upper end of a cover beam or a pier, when a heavy-duty car passes through the bridge deck of the viaduct, vibration and gravity of the heavy-duty car passing through the bridge are transmitted to the beam body through wheels, the beam body is transmitted to a longitudinal sliding upper block, the longitudinal sliding upper block is transmitted to an annular oblique-folding spring or a disc spring, the annular oblique-folding spring or the disc spring eliminates the vibration and then transmits the gravity to a longitudinal sliding lower block, and then the gravity is transmitted to a bearing part of a guide sliding seat body; after absorbing the vibration and shock transmitted from the upper surface, the annular oblique-folding spring generates slight elastic fluctuation from the circular hole of the annular oblique-folding spring to the lower annular body, the small end of the tubular annular body, the large end of the tubular annular body and the upper annular body, so that the vibration and shock generated by the truck passing through the bridge deck of the viaduct are eliminated; when the annular inclined folding spring bears the gravity transmitted from the upper surface, the gravity presses the tapered pipe annular body at the middle part of the annular inclined folding spring from the upper annular body of the annular inclined folding spring and presses the lower annular body of the annular inclined folding spring to ensure that the tapered pipe annular body at the middle part of the annular inclined folding spring is outwards contracted from the large end of the tapered pipe annular body to the small end of the pipe annular body so as to form elastic contraction, the lower annular body is elastically contracted towards the circular hole, and the upper annular body is elastically expanded towards the outer annular surface, so that the deformed annular inclined folding spring bears the weight of the beam body and the truck; after the disk spring absorbs the vibration and shock transmitted from the upper surface, slight elastic fluctuation from the conical round hole of the disk spring to the outer circular surface is generated up and down, so that the vibration and shock generated to the bridge deck of the viaduct when the lorry passes through the viaduct are eliminated; when the disc spring bears the gravity transmitted from the upper surface, the gravity is pressed from the large end of the conical surface of the disc spring to the small end of the conical surface and then contracts, so that the deformed disc spring bears the weight of the beam body and the truck;
when the lorry on the bridge deck of the viaduct passes through the single side, the pressure of the girder body on one side of the load-bearing lorry, which presses the longitudinal sliding upper block and the annular oblique folding spring or the disc spring, is increased, and the pressure of the girder body on one side of the lorry, which does not bear the load-bearing lorry, which presses the longitudinal sliding upper block and the annular oblique folding spring or the disc spring is reduced; at the moment, the beam body on one side without bearing the truck presses the longitudinal guide sliding group and cannot move upwards and slide towards two sides in the guide sliding groove of the guide sliding seat body, the beam body on one side without bearing the truck presses the longitudinal guide sliding group and cannot move downwards and slide towards the outside in the guide sliding groove of the guide sliding seat body, the longitudinal guide sliding group is locked and limited and cannot move upwards and downwards and slide towards the side in the guide sliding groove of the guide sliding seat body, so that when the truck on the bridge floor of the viaduct passes through the single-side overload, the viaduct of the single-pier single-support supporting beam body cannot be laterally turned over due to the locking and limiting between the guide sliding seat body and the longitudinal guide sliding group, and the stability of the single-pier single-support viaduct when the truck passes through the viaduct is improved; meanwhile, after the anti-rollover metal vibration reduction support is adopted, the viaduct with an impatient bend can be changed into a viaduct supported by single piers, so that the construction cost of the viaduct is reduced;
when weather changes, the beam body contracts or extends along with the change of temperature, and the longitudinal guide sliding group is driven to longitudinally move in the guide sliding groove in the guide sliding seat body, so that the pulling force or the pushing force of the beam body to the bridge pier when the beam body contracts or extends is eliminated, and the bridge pier does not deviate or skew.
The anti-rollover metal vibration reduction support is suitable for installing and using the viaduct of the single-support supporting beam body of the transverse single pier, or for installing and using the viaduct of the single-support supporting beam body of the transverse double piers and the transverse multi-pier and the multi-support supporting beam body, is also suitable for replacing the traditional support, and is also suitable for installing and using the anti-rollover support for replacing the traditional support to prevent the side rollover of the beam body of the viaduct.

When the annular oblique-folding spring and the disk spring bear gravity, the annular oblique-folding spring and the disk spring have the elastic function of the spring through the conical deformation generated in the axial direction of the circular mandrel, so that the large spring is simple in structure and convenient to manufacture.
The anti-rollover safety coefficient of the traditional support is only 40-50% of the bearing capacity of the support, the anti-rollover safety coefficient is improved to the anti-rollover metal vibration reduction support which is dozens of times to hundreds of times of the bearing capacity of the traditional support, the anti-rollover capacity of the viaduct with the single support supporting beam body is obviously improved, and the bearing safety of the viaduct with the single support supporting beam body and the passing safety of the high load of the truck continuously passing through the viaduct are improved.
