Description
Technical field
The present invention relates to technical field of bridge engineering, be specifically related to a kind of cable-stayed bridge cable anchor system.
Background technology
Cable stayed bridge is due to features such as its deck-molding are less, span ability is larger, handsome in appearance, in widely applied in the large bridge construction across footpath.Conventional cable stayed bridge is made up of members such as bridge tower, drag-line, girders.Drag-line one end is anchored in girder, and one end is anchored in bridge tower.Anchor type between drag-line and bridge tower mainly contains that anchor is boxly connected, otic placode formula connects, anchor tube formula connects.In these anchor types, anchorage element only connects with tower wall or tower inner member.
Due to features such as cable stayed bridge beautiful designs, there is the civic landscape cable stayed bridge of Medium Span.A wherein class cable stayed bridge, span of bridge is little, and bridge tower modern design is attractive in appearance, and bridge tower is made up of with upper pillar stand outer crossbeam and two, and the single pillar construction size of bridge tower is less.Because space in bridge tower is less, in conventional tower, anchor case connects because needs larger space is difficult to adopt.The otic placode formula that is anchored in tower wall outside connects and is connected and has a strong impact on Bridge Landscape effect with anchor tube formula.Therefore, be badly in need of according to the construction features of bridge tower, do not affecting under the prerequisite of Bridge Landscape, realize the anchor connection of suspension cable on bridge tower.
Summary of the invention
For the problems referred to above, the present invention proposes the outer crossbeam oblique anchor-hold system of a kind of tower, can not only realize reliable connection the between drag-line and bridge tower, and not affect Bridge Landscape effect.
Realization of the present invention is completed by following technical scheme: the outer crossbeam oblique anchor-hold system of a kind of tower, described anchor system is arranged at the crossbeam between tower column, described crossbeam comprises top board, base plate, web, described tower column comprises tower wallboard, diaphragm, vertical clapboard, it is characterized in that, in described crossbeam, anchor-hold member is set, described anchor-hold member and cantilever diaphragm and tower column tower wallboard are welded to connect.
Described anchor-hold member is made up of anchoring base plate, anchoring force transmitting board, anchoring frange plate, anchoring stiffening plate and noose pipe, anchoring base plate is connected with anchoring frange plate, anchoring force transmitting board, anchoring stiffening plate, and anchoring force transmitting board and anchoring stiffening plate form groined type beam mutually.
Described crossbeam top board, base plate is corresponding with described tower column diaphragm and be welded to connect with tower wallboard, and described cantilever diaphragm is corresponding with described tower column vertical clapboard and be welded to connect with tower wallboard.
Described anchoring stiffening plate is shorter than anchoring force transmitting board, and described anchoring force transmitting board and described cantilever diaphragm and bridge tower wallboard are welded to connect, and described anchoring stiffening plate and anchoring frange plate are connected on described anchoring force transmitting board.
In the inner side of tower column tower wallboard, tower wall stiffener is also set.
Described tower wallboard is offered drag-line via hole, and described noose pipe is welded in described tower wallboard inner side, and corresponding with described drag-line via hole.
Advantage of the present invention is: 1. can realize the Sarasota anchor connection at small size bridge tower place; 2. anchoring structure is positioned at the outer crossbeam of tower, and the structure of simplifying in tower column is arranged; 3. bridge tower be cannot see anchoring structure outward, and landscape effect is good; 4. the outer crossbeam of tower can be used as operating platform, is convenient to construction, detection, maintenance and the replacing of suspension cable.

Detailed description of the invention
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1-Fig. 6, figure acceptance of the bid note is respectively: anchorage element 1, crossbeam top board 2, crossbeam base plate 3, cantilever diaphragm 4, tower column tower wallboard 5, tower column diaphragm 6, tower column vertical clapboard 7, anchoring base plate 8, anchoring frange plate 9, anchoring force transmitting board 10, anchoring stiffening plate 11, noose pipe 12, tower wall stiffener 13.
Embodiment: as depicted in figs. 1 and 2, the present embodiment provides a kind of tower outer crossbeam oblique anchor-hold system.Anchorage element 1 is welded to connect with cantilever diaphragm 4 and tower column tower wallboard 5.The anchored force of suspension cable is mainly passed to cantilever diaphragm 4 by anchorage element 1, and because anchorage element 1 is also connected with tower column tower wallboard 5, part anchored force also passes on tower column tower wallboard 5.Cantilever diaphragm 4 is corresponding with tower column vertical clapboard 7 positions, and crossbeam top board 2 and crossbeam base plate 3 are corresponding with tower column diaphragm 6 positions, and crossbeam top board 2, crossbeam base plate 3, cantilever diaphragm 4 are directly welded to connect in tower column tower wallboard 5.By above plate annexation, anchoringwire power reliable delivery has arrived on tower column.
As shown in Fig. 3-Fig. 6, anchorage element 1 is made up of anchoring base plate 8, anchoring frange plate 9, anchoring force transmitting board 10, anchoring stiffening plate 11, noose pipe 12.Stay Cable Anchors is directly bearing on anchoring base plate 8, by contact, drag-line power is passed to anchoring base plate 8.Anchoring base plate 8 is connected with anchoring frange plate 9, anchoring force transmitting board 10, anchoring stiffening plate 11, advocating to pass to anchoring force transmitting board 10 and anchoring stiffening plate 11.Anchoring force transmitting board 10 and anchoring stiffening plate 11 form groined type beam mutually.Anchoring stiffening plate 11 is shorter than anchoring force transmitting board 10, and is attached on anchoring force transmitting board 10, and the anchored force that anchoring stiffening plate 11 is shared is finally passed to anchoring force transmitting board 10.As previously mentioned, anchoring force transmitting board 10 is connected with cantilever diaphragm 4 and tower column tower wallboard 5, by power being passed to cantilever diaphragm 4 and tower column tower wallboard 5, and then anchored force is spread apart.The groined type beam that anchoring frange plate 9 forms for anchoring force transmitting board 10 and anchoring stiffening plate 11 be subject to curved stiffener, can effectively reduce the distortion of groined type beam.Meanwhile, tower column tower wallboard 5 also plays a part identical with anchoring frange plate 9 to a certain extent.Noose pipe 12 passes tower column diaphragm 6, and is welded to connect with tower column tower wallboard 5, and corresponding with the well word channel position of groined type beam, to facilitate passing of drag-line.In order to reduce the distortion of tower column tower wallboard 5, in the inner side of tower column tower wallboard 5, tower wall stiffener 13 is set.
The outer crossbeam oblique anchor-hold system of this tower can realize the Sarasota anchor connection at small size bridge tower place.Anchoring structure is positioned at the outer crossbeam of tower, has simplified the structure in tower column and has arranged.Bridge tower be cannot see anchoring structure outward, and landscape effect is good.The outer crossbeam of tower can be used as operating platform, is convenient to construction, detection, maintenance and the replacing of suspension cable.
