Abstract
The utility model discloses a permanent and temporary combined rotation body support system. The system comprises a supporting leg, a support, a cyclic annular mirror surface stainless steel plate, an upper rotating shaft and a shaft sleeve, wherein the bottom of the supporting leg and the bottom of the support are fixedly arranged on an abutment wall, the mirror surface stainless steel plate is embedded in the bottom of a beam body, the upper rotating shaft is embedded in the center of the beam body, and the shaft sleeve is embedded in the center of the abutment wall. A Teflon sliding plate is fixedly arranged on the top of the support. The shaft sleeve is provided with a lower rotating shaft. A gap is reserved between the top of the supporting leg and the mirror surface stainless steel plate. The upper rotating shaft and the lower rotating shaft are connected into a whole through a bolt. According to the permanent and temporary combined rotation body support system, the permanent support is slightly transformed to be a rotating body support, the rotating body support is used as a beam body permanent support after being completed, and the function of the support is continuously achieved. Meanwhile, the various functions of the permanent support are not changed.
Description
Technical field
The utility model relates to bridge construction technical field, is specially one and forever faces in conjunction with rotation body support system.
Background technology
In order to reduce the particularly safety operation impact of high-speed railway of existing railway, for continuous beam or cable stayed bridge, some conventional construction methods are as free cantilever casting, and support cast-in-place etc. are all forbidden to adopt, adopt more cross-line construction short, to both little rotation swivel construction methods of wired Influence to operation.General rotation swivel construction method is at the bottom of pier beam temporary consolidation, pier, rotation system to be set, and after rotateing in place, with concrete, rotation system is enclosed in bridge pier, removes subsequently temporary consolidation and completes system conversion.But for high pier, because of the significantly increase of pier shaft weight, the system of rotating at the bottom of pier need to arrange large tonnage ball pivot, and bridge pier is higher, constructs very dangerous.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure forever facing in conjunction with rotation body support system in order to overcome above-mentioned deficiency.
The utility model comprise bottom be fixedly installed on spike and bearing on pier, be embedded in beam body bottom circular mirror face stainless steel plate, be embedded in the upper axis of rotation at Liang Ti center and be embedded in the axle sleeve at pier center, described bearing top is fixedly installed tetrafluoro slide plate, described axle sleeve is provided with Shaft, between described spike top and mirror face stainless steel plate, be provided with gap, described upper axis of rotation is connected by bolt with Shaft.
The number of described spike is 4 or 8 and is arranged symmetrically.
Gap between described spike top and mirror face stainless steel plate is 5mm.
The permanent bearing of the utility model utilization is transformed formation rotation body support a little, after the end of turning, as beam body permanent support, continues the effect of performance bearing.Meanwhile, all do not change as the various functions of permanent bearing.

The specific embodiment
Further illustrate the utility model below in conjunction with drawings and Examples.
Embodiment: the utility model comprise bottom be fixedly installed on spike 1 and bearing 5 on pier 10, be embedded in beam body 11 bottoms circular mirror face stainless steel plate 3, be embedded in the upper axis of rotation 6 at Liang Ti 11 centers and be embedded in the axle sleeve 9 at pier 10 centers, described bearing 5 tops are fixedly installed tetrafluoro slide plate 4, described axle sleeve 9 is provided with Shaft 8, between described spike 1 top and mirror face stainless steel plate 3, be provided with gap, described upper axis of rotation 6 is connected by bolt 7 with Shaft 8.The number of described spike 1 is 4 or 8 and is arranged symmetrically.Gap between described spike 1 top and mirror face stainless steel plate (3) is 5mm.
At the pre-buried pull rope 2 in the boss position at Liang Ti 11 centers, pull rope 2 is steel strand, circular mirror face stainless steel plate 3 is some little corrosion resistant plate spicing forming types, upper axis of rotation 6 is a rod iron, weld some reinforcing bars or cushion block around, Shaft 8 is a rod iron, be placed in axle sleeve 9, but bottom does not contact with axle sleeve 9.Bearing 5 bottoms are fixed on design attitude, all vertical loads of beam body 11 are born by bearing 5, and when pulling equipment pulling traction rope 2, beam body 11 rotates with Shaft 8 along upper axis of rotation 6, axis of rotation can play rotating shaft effect, simultaneously can 11 horizontal movements of restraint beam body.Axis of rotation does not contact with any because of bottom, does not therefore bear vertical load, and it is in order to reduce the friction factor while rotating that bearing 5 tops increase tetrafluoro slide plates 5 and mirror face stainless steel plate 3 antithesis.Spike 1 keeps gap 5mm with mirror face stainless steel plate 3, is only used to prevent the side direction overturning effect of beam body 11, does not rotate to support to use.Turn after end, take bolt 7 apart axis of rotation 6 is separated with Shaft 6, can take away.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
Claims (3)
1. one kind is faced forever in conjunction with rotation body support system, comprise that bottom is fixedly installed on spike (1) and the bearing (5) on pier (10), be embedded in the circular mirror face stainless steel plate (3) of beam body (11) bottom, be embedded in the upper axis of rotation (6) at beam body (11) center and be embedded in the axle sleeve (9) at pier (10) center, it is characterized in that: described bearing (5) top is fixedly installed tetrafluoro slide plate (4), described axle sleeve (9) is provided with Shaft (8), between described spike (1) top and mirror face stainless steel plate (3), be provided with gap, described upper axis of rotation (6) is connected by bolt (7) with Shaft (8).
