Technical field
The invention belongs to the bridge technology field, particularly relate to a kind of bridge rotation construction structure.
Background technology
Due to the particularity of bridge construction, in bridge construction process, need to use multiple construction technology, Bridge Rotation Construction Technique is wherein important a kind of.Rotator construction is with respect to other form of construction work, and difficulty of construction is larger, but due to its traffic impact minimum to the intersection position, often adopts in present bridge construction.
Be to reduce the overall structure center of gravity, the operation of usually bridge pier and beam body integral body being turned, common method is the method for flatting turn.
The rotor of the method for flatting turn system mainly contains the rotating support system, rotates trailer system and balance sysmte.The rotating support system is the key equipment that the method for flatting turn is constructed, and is made of top rotary table and lower rotary table.Top rotary table supporting rotational structure, lower rotary table and basis link.Rotate with respect to lower rotary table by top rotary table, reach the purpose of turning.
The several functions such as the rotating support system must take into account and turn, load-bearing and balance.Equilibrium conditions when pressing rotating support, rotating support can be divided into the supporting of the mill heart, spike supporting and the mill heart and spike supports three types jointly.
A key issue that exists in the process of flatting turn is the equilibrium problem in the process of turning.Rotate center of gravity and be generally the bridge pier axle center, reduce for making center of gravity, at the bottom of usually rotating disk being located at pier, need to add the purpose that counterweight has reached balance in rotation.
Generally bear whole rotation weight by the mill heart, usually be inserted with positioning rotating shaft at the mill heart.In order to guarantee safety, usually be provided with thrust wheel or feet around supporting turntable.During normal rotation, thrust wheel or supporting foot do not contact with chute surface, are inclined to play supporting role in case have to topple.
But some bridge is due to the particularity of its geographical position of living in and this body structure, can't adopt scheme of rotation at the bottom of pier, has railway line to pass through in the bridge bottom, and allows just must adopt rotator construction in very short situation break period.Each bridge pier is comprised of two parts, can't adopt and rotate constructure scheme at the bottom of pier.So a kind of security performance of necessary design is good, the bridge rotation construction structure of easy construction.
Summary of the invention
It is good that purpose of the present invention just is to provide a kind of security performance, has railway line to pass through in the bridge bottom, and allow in very short situation break period can convenient construction bridge rotation construction structure.
Purpose of the present invention realizes by following technical proposals:
a kind of bridge rotation construction structure, comprise beam body and bridge pier, also comprise the vertical force bearing, spherical rotation twisted axis, the slip casing, cable wire, directive wheel, reaction frame, jack, auxiliary pier, the beam body by the vertical force bearing be connected the rotation twisted axis and be connected with bridge pier, the bridge pier end face has deep-slotted chip breaker, the vertical force bearing is placed in this deep-slotted chip breaker, and corrosion resistant plate is laid in the deep-slotted chip breaker bottom surface, vertical force bearing lower surface is provided with polyfluortetraethylene plate, connect by binder between bridge pier, spherical rotation twisted axis is connected with the beam body in the middle part of being arranged on binder, slip casing upper end is fixed on beam end of body bottom surface, the lower end contacts with bridge pier, reaction frame is arranged at bridge pier top also anchoring, jack one end is fixed on reaction frame, the other end connects an end of cable wire, the other end of cable wire is anchored on the slip casing, and contact with a plurality of directive wheels that are arranged on bridge pier top outer wall along beam body rotation tangential direction in the middle of cable wire, beam body below is symmetrically arranged with two auxiliary piers with beam body length vertical direction, and on auxiliary pier, corresponding bridge pier is provided with the identical cable wire of function, directive wheel, reaction frame and jack.
Further, offer anchor hole on described slip casing, an end of cable wire is by this anchor hole and the anchoring of slip casing.
Beneficial effect of the present invention is: safety is good, has railway line to pass through in the bridge bottom, and allows can construct easily in very short situation break period, and not only velocity of rotation is fast, and can peak discharge reduces the break period of road under bridge.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A to enlarged drawing;
Fig. 3 is Construction Principle figure of the present invention.
The specific embodiment
as depicted in figs. 1 and 2, a kind of bridge rotation construction structure, comprise beam body 1 and bridge pier 3, also comprise vertical force bearing 7, spherical rotation twisted axis 6, slip casing 2, cable wire, directive wheel 4, reaction frame 8, jack 9, auxiliary pier 10, beam body 1 by vertical force bearing 7 be connected rotation twisted axis 6 and be connected with bridge pier 3, bridge pier 3 end faces have deep-slotted chip breaker to adapt to the needs of turning, vertical force bearing 7 is placed in this deep-slotted chip breaker, and corrosion resistant plate is laid in the deep-slotted chip breaker bottom surface, vertical force bearing 7 lower surfaces are provided with polyfluortetraethylene plate, connect by binder 5 between bridge pier 3, spherical rotation twisted axis 6 is arranged on binder 5 middle parts and is connected with beam body 1, and play position-limiting action, slip casing 2 upper ends are fixed on beam body 1 end bottom surface, the lower end contacts with bridge pier 3, and bear pulling force effect in rotation, reaction frame 8 is arranged at bridge pier 3 tops also anchoring, jack 9 one ends are fixed on reaction frame 8, the other end connects an end of cable wire, the other end of cable wire is anchored on slip casing 2, and contact with a plurality of directive wheels 4 that are arranged on bridge pier 3 top outer walls along beam body 1 rotation tangential direction in the middle of cable wire, make the glide direction of cable wire all the time along the tangential direction of turning and rotating, play the effect that reduces to rub with correct guidance, beam body 1 below and beam body 1 length vertical direction are symmetrically arranged with two auxiliary piers 10, on auxiliary pier 10, corresponding bridge pier 3 is provided with the identical cable wire of function, directive wheel, reaction frame and jack (not shown in FIG.) and assists reinforcing for rotating when occurring stagnating at beam body 1, completes construction.This auxiliary pier 10 is used for bearing at rotator construction and occurs that beam body 1 two ends unbalance stress causes and the gravity that occurs, in case beam body 1 topples.
As shown in Figure 3, when construction, bridge pier 3 both sides jack 9 constantly pull cable wire that beam body 1 is rotated along the revolution tangential direction while application of force, and central spherical is rotated twisted axis 6 and rotated under the effect of power, and carries out spacing.Two vertical force bearings 7 of beam body 1 both sides slide along bridge pier 3 top arc areas, and slide plane is polyfluortetraethylene plate and corrosion resistant plate contact surface.Stagnate if there is causing because of factors such as frictional force increases rotating in rotation process, can start jack pair beam body 1 application of force on auxiliary pier 10, be rotated further.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
