Abstract
The utility model provides a bridge swivel construction bearing which is characterized by mainly comprising a pier body, a positioning steel mandrel, concrete buttresses, a bearing platform, a jack counter-force seat, an outer slide rail, a rotary disk and steel pipe concrete support legs, wherein the pier body, the rotary disk and the steel pipe concrete support legs form an upper half portion of the swivel construction bearing, the positioning steel mandrel, the concrete buttresses, the bearing platform, the jack counter-force seat and the outer slide rail form a lower half portion of the swivel construction bearing, and the upper half portion and the lower half portion can mutually rotate by means of slide. By means of the application of the bridge swivel construction bearing, expensive supports do not need to be set up, installation and set-up working procedures are reduced, high altitude operations and operations at sea, which are complicated and strong in technicality can be changed into shoreside land operations, on one hand, the construction is safe and quality is recommendable, and on the other hand, in the construction of a navigable river or a cross-line overpass with frequent vehicles, traffic can not be interrupted, and uninterrupted navigation can be achieved, damage to environment is reduced, construction cost and mechanical equipment are reduced, and the bridge swivel construction bearing has great technical and economic benefits and social benefits.
Description
Technical field
The utility model relates to the engineering construction field, specifically is a kind of employing rotator construction bearing.
Background technology
During road and bridge is built, in order to guarantee the current safety such as highway that bridge crosses over, railway, rivers navigation channel, must take the iceound measure of part, this inevitably can impact the normal, safe, unimpeded, current of navigation channel, easily causes the navigation channel to stop up; Or to highway or the measure of railway employing envelope line, not only can affect normal passing through, also can have influence on safety and the progress of engineering self simultaneously.In order both to guarantee engineering construction safety, reduce the unimpeded impact in navigation channel again as far as possible, shorten iceound, the envelope line time, and reducing construction cost, the bridge rotating technology is arisen at the historic moment.
Common highway, bridge rotation body sliding support construction great majority adopt the concrete structure that arranges separately or steel structure member as turning the mill heart, complex structure, turn finish after, must remove these when mounted required members.Outside original Structural Engineering, not only increase engineering cost like this, wasted again a large amount of engineering materials, but also prolonged the progress of whole engineering, thus, greatly reduced the efficiency of construction of engineering.
The utility model content
The purpose of this utility model is to overcome the deficiency that existing mode exists, and provides a kind of Bridge Rotation Construction Technique bearing after improving, and this rotary body device has and rotates flexibly through optimal design, and rotating torque is little, the characteristics that bearing capacity is large.
The utility model is achieved in that a kind of Bridge Rotation Construction Technique bearing of structure, it is characterized in that; The rotator construction bearing mainly is comprised of pier shaft, location steel axle, concrete buttress, cushion cap, jack counter-force seat, external slideway, rotating disk, concrete filled steel tube supporting leg;
Wherein pier shaft, rotating disk, concrete filled steel tube supporting leg form the first half of rotator construction bearing, location steel axle, concrete buttress, cushion cap, jack counter-force seat, external slideway form the latter half of rotator construction bearing, can mutually rotate by sliding between the top and the bottom.
According to a kind of Bridge Rotation Construction Technique bearing described in the utility model, it is characterized in that: described external slideway is comprised of the polyfluortetraethylene plate of corrosion resistant plate and antithesis, diameter is about 10 meters, this device steadily, reliably, bear the weight of turning large, rotate the center of gravity of system and the eccentricity value that the lower rotary table axle center can allow trace.
According to a kind of Bridge Rotation Construction Technique bearing described in the utility model, it is characterized in that: concrete filled steel tube supporting leg bottom is provided with polyfluortetraethylene plate, can be in the enterprising line slip of slideway, and it has the balanced support effect simultaneously.
A kind ofly adopt above-mentioned Bridge Rotation Construction Technique bearing to carry out the side of bridge construction
MethodIt is characterized in that: the latter half of construction bridges at first, carry out the construction of bridge the first half along construction bridge axis again after finishing, after finishing, passes through Superstructure Construction tumbler, carry out pushing tow by jack counter-force seat, then the first half of whole bridge just can be rotated around the location steel axle, when bridge axes turns to and designs the bridge axis when consistent, stop operating, carry out next step construction after then bridge the first half being fixed
The beneficial effects of the utility model are: use the support that rotator construction bearing described in the utility model can not set up somewhat expensive, reduce to install and set up operation, the land operation that complicated, technical strong work high above the ground and operation at sea are become the bank, not only construction safety, quality are desirable, and can not disturb traffic, uninterrupted navigation in the construction of cross-line overpass bridge frequently at navigable river or vehicle, reduce infringement to environment, reduce operating expenses and plant, be to have good technical economic benefit and social benefit.This rotary body device also has and rotates flexibly through optimal design, and rotating torque is little, the characteristics that bearing capacity is large.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
A kind of novel Bridge Rotation Construction Technique bearing that provides of the present utility model, this rotator construction bearing have the characteristics flexible, that rotating torque is little, bearing capacity is large of rotating through optimal design; As among Fig. 1-2 as can be known, the rotator construction bearing mainly is comprised of pier shaft 1, location steel axle 2, concrete buttress 3, cushion cap 5, jack counter-force seat 6, external slideway 7, rotating disk 8, concrete filled steel tube supporting leg 9; Wherein pier shaft 1, rotating disk 8, concrete filled steel tube supporting leg 9 form the first half of rotary body device, location steel axle 2, concrete buttress 3, cushion cap 5, jack counter-force seat 6, external slideway 7 form the latter half of rotary body device, wherein can mutually rotate by sliding between the top and the bottom.
According to designing requirement, at first the latter half of construction bridges is carried out the construction of bridge the first half along construction bridge axis after finishing again.By tumbler, carry out pushing tow by jack counter-force seat after Superstructure Construction is finished, then the first half of whole bridge just can be rotated around the location steel axle.When bridge axes turns to and designs the bridge axis when consistent, stop operating, carry out next step construction after then bridge the first half is fixing.
External slideway 7 mainly is comprised of the polyfluortetraethylene plates of corrosion resistant plate and antithesis, diameter about 10 meters, this device steadily, reliable, bear the weight of turning large, the center of gravity of rotating system can allow micro-eccentricity value with the lower rotary table axle center.
Rotating disk 8 is a kind of take the tumbler of hinge as the axle center load-bearing.Its feature is that the center of gravity of whole rotation system must drop on the hinge of axle center, and spherical hinge both played the role of positioning, and bore again the gravity of all turning.
Concrete filled steel tube supporting leg 9 bottoms are provided with polyfluortetraethylene plate, can be in the enterprising line slips of slideway, and it has the balanced support effect simultaneously.
