Said thick pillar girder system is constituted by some thick pillar beams and some linking beams, and said linking beam is located between per two adjacent thick pillar beams, and said thick pillar beam is connected as a single entity, and said spacing hole vertically is opened on the said linking beam.
Said limited post is the cuboid steel framed structure.
The utility model has the advantages that: the gap through between the thick pillar girder system is provided with limited post, is inwall and the realization of the conflict between limited post position-limiting action through the perforate of thick pillar girder system in jacking, has avoided the damage of damage building or structure; And can stopping means be set at the multiple spot at thick pillar girder system place, and spacing position is disperseed, avoided excessive for building, structure local pressure.
Description of drawings
Accompanying drawing 1 is this device overall structure sketch map.
The specific embodiment
Through embodiment the utility model characteristic and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As shown in Figure 1, label 1-6 representes respectively: bent cap 1, bridge pier 2, thick pillar beam 3, linking beam 4, limited post 5, foundation underpinning 6.
Referring to Fig. 1, present embodiment combines the disconnected capital of bridge to rise construction operation to be elaborated for the concrete structure of stopping means:
When the disconnected post of bridge was constructed, the building unit that relates to mainly comprised bent cap 1, bridge pier 2, thick pillar beam 3 and linking beam 4, and wherein thick pillar beam 3 is exactly to be attached to post (bridge pier 2) girder system all around, is a kind of theory that underpins, and in translation and bridge jacking, has used more.During jacking, jack-up hydraulic ram passes to thick pillar beam 3 to power, and thick pillar beam 3 passes to bridge pier 2 to power again, and bridge pier 2 passes to superstructure (bent cap 1 etc.), the friction Transfer of Shear through new and old concrete between thick pillar beam 3 and the bridge pier 2.Referring to Fig. 1, have three posts respectively at the same bridge pier 2 of bridge in the present embodiment, have respectively on it between 3, three thick pillar beams 3 of thick pillar beam and connect into a thick pillar girder system with linking beam 4.
Each linking beam 4 is rectangular-shaped frame type reinforced concrete structure, is located between per two adjacent thick pillar beams 3, and said thick pillar beam 3 is connected as a single entity.Wherein has perforate in the frame construction of linking beam 4; This perforate is cuboid frame sidewall and vertically is provided with, and present embodiment has utilized the built-up section of this perforate as stopping means just, i.e. spacing hole; Corresponding, a limited post 5 is set on the position of foundation underpinning 6 corresponding spacing holes.Limited post 5 is the cuboid steel framed structure; Its bottom is fixed on the said foundation underpinning 6; Said limited post 5 changes in said spacing hole with said spacing hole form fit and quilt cover, has certain clearance between said limited post 5 and the said spacing hole, forms matched in clearance.This spacing gap can suitably be adjusted through increasing steel plate.
When jacking; Through the mutual conflict between limited post 5 outer surfaces and the spacing hole inwall; Each limited post 5 can limit superstructure moving of four direction in the horizontal direction; And the rotation of level, so limited the displacement of superstructure, and before jacking He in the jacking, can carry out trickle adjusting through steel plate.And spacing hole and limited post 5 can be set on the multiple spot position of thick pillar girder system, so spacing position is disperseed, avoided excessive for building, structure local pressure.
Although above detailed description through embodiment describes for the technical scheme of the utility model, the scope of law that should be appreciated that this description is limited the words of the utility model appending claims.It only is exemplary should being interpreted as for the detailed description of stopping means in the foregoing description, rather than comprises the embodiment that each is possible.Even because exhaustive each possible embodiment be not impossible also be unpractical.So those skilled in the art should recognize that obviously spacing hole can directly utilize the gap on the thick pillar girder system in the stopping means, also can when pouring into a mould the thick pillar girder system, be chosen in targetedly and reserve some spacing holes on the thick pillar girder system according to operating mode.Spacing hole and limited post shape also select also not only to be confined to this simultaneously; As long as the sidewall of limited post, spacing hole vertically is provided with and cooperatively interacts; The displacement that makes progress when not retraining the superstructure jacking can realize spacing function; The time can combine actual condition to select other other shapes in construction, like cylindric, prism-shaped etc., and this still falls within the scope of claims.
