Abstract
The utility model discloses a wind resisting structure of a flatwise tensile rope bridge. The wind resisting structure comprises steel ropes (1). Two ends of each steel rope (1) are fixed to bridge abutments. Each steel rope (1) passes through a support (3) longitudinally. The support (3) is fixed on one steel cross beam (2) which is disposed at a midspan position of the flatwise tensile rope bridge. Through increase of distance between the inner side supports disposed at two ends of the steel cross beam respectively and reinforcement anti-roll rigidity of an overall bridge deck, the wind resisting effect is achieved. Compared with the conventional wind resisting structure, the wind resisting structure of the flatwise tensile rope bridge has a standardized structural form, demands less for topography, is easy to install, requires less materials, improves safety of operation of the flatwise tensile rope bridge greatly and is worthy of promotion.
Description
Technical field
The utility model relates to the wind resisting structure on a kind of horizontal drawing cable bridge, belongs to bridge with the technical field of constructing of wind resisting structure.
Background technology
In traffic of mountain area, the horizontal drawing cable bridge is widely applied as a kind of common bridge type is short with the duration of building, cost is low.Usually the wind resisting structure in the horizontal drawing cable bridge is some places during an end is connected to spanning respectively with several cable wires, is symmetrical in the bridge axis arranged, and the other end is connected on the massif of both sides, and these cable wires are strained when being subjected to wind load, thereby reach the windproof effect.Therefore or undesirable but this wind resisting structure is had relatively high expectations to the two sides landform, and wind cable cable wire quantity is more, construct more complicated, and the wind cable is in use easily loose and lost efficacy.
Summary of the invention
The purpose of this utility model is to provide a kind of standardized horizontal drawing cable bridge wind resisting structure, and this structure can satisfy the normal use of horizontal drawing cable bridge, and the side direction wind resistance that satisfies horizontal drawing cable bridge requirement can be provided, and result of use is good, to overcome the deficiencies in the prior art.
For realizing the purpose of this utility model, the wind resisting structure of horizontal drawing cable bridge of the present utility model has also adopted cable wire as parts of windproof, wherein, the two ends of this cable wire are separately fixed on abutment, every cable wire vertically passes a support, this support is fixed on a gooseneck, and gooseneck is arranged on horizontal drawing cable bridge span centre position.Horizontal drawing cable bridge wind resisting structure of the present utility model like this has standardized form of structure, and is less demanding to landform, easy for installation, and material quantity is less.
Further, support is positioned at the transverse ends of gooseneck, and is arranged symmetrically with.Cable wire can force balance on gooseneck like this.
In addition, support respectively from inside to outside is arranged side by side three in the transverse ends of every gooseneck, and each support correspondence is passed a cable wire, on every gooseneck, in fact six supports is arranged like this, and by six roots of sensation gooseneck.Certainly, the quantity of support and cable wire is not limited to this, also can increase and decrease according to actual conditions, to guarantee that its intensity and balance are as good.
Further, in order to guarantee the whole anti-inclined rigidity of bridge floor, the support of gooseneck transverse ends need to have certain spacing, preferably guarantees two of the gooseneck two ends spacing 1m at least of support in the inner part.
Owing to having adopted technique scheme, the utility model is strengthened the anti-roll stiffness of bridge floor integral body, thereby is reached the windproof effect by increasing the distance between gooseneck two end supports.Compared with prior art, horizontal drawing cable bridge wind resisting structure of the present utility model has standardized form of structure, and less demanding to landform, easy for installation, material quantity is less, has greatly strengthened horizontal drawing cable bridge Operation safety, is worthy to be popularized.
Description of drawings
Fig. 1 is floor map of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the gooseneck schematic diagram in Fig. 1;
Fig. 4 is the support schematic diagram in Fig. 1.
Being labeled as in accompanying drawing: 1-cable wire, 2-gooseneck, 3-support.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1 and Fig. 2, the two ends of the cable wire 1 that the wind resisting structure of horizontal drawing cable bridge of the present utility model adopts are separately fixed on abutment (in figure for indicating abutment), every cable wire 1 vertically passes a support 3, and this support 3 is fixed on a gooseneck 2, and gooseneck 2 is arranged on horizontal drawing cable bridge span centre position.
As can see from Figure 1, support 3 is positioned at the transverse ends of gooseneck 2, and is arranged symmetrically with, and cable wire 1 has also formed two bundles so in fact, is connected to the two ends of gooseneck 2.The support 3 of showing in figure respectively from inside to outside is arranged side by side three in the transverse ends of every gooseneck 2, and two bundle cable wires 1 respectively are comprised of three cable wires 1.
In order to guarantee the anti-rollover performance of structure, the spacing of two medial cradle 3 of gooseneck 2 transverse ends is 1m at least, also the nearest spacing of instant two bundle cable wires 1.
The gooseneck 2 that the utility model adopts and the shape and structure of support 3 respectively as shown in Figure 3 and Figure 4, gooseneck 2 is structures of i iron processing, support 3 is the structures by steel plate processing, wherein is provided with a bearing pin and is convenient to cable wire 1 and passes wherein.Support 3 in a row is welded on the two ends of gooseneck 2.
The below further illustrates as follows to implementation process of the present utility model and principle again:
As shown in Figure 1, the utility model is implemented by following key step: the size of a) determining wind load according to standard or actual security needs; B) according to the distance between radical, specification and the gooseneck 2 two ends wind-cables 1 of the size of wind load and the required gooseneck 2 one side wind-cables 1 of related specifications calculative determination; C) determine distance between 2 liang of end supports 3 of gooseneck by the distance between gooseneck 2 two ends wind-cables 1; D) determined the length of gooseneck 2 by the distance between 2 liang of end supports 3 of gooseneck, gooseneck 2 one end support 3 spacings and gooseneck 2 termination length; E) according to the installation of finishing device on the horizontal drawing cable bridge shown in Figure 1.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
