Abstract
The invention discloses a dispersed cable saddle structure for a bridge, comprising a saddle bow (1), a saddle component and a pad stone (3); the saddle bow (1) is supported on the pad stone (3) through the saddle component; the saddle component comprises an upper support base plate (4), a middle lining plate (5) and a lower support base plate (6); a cylindrical surface sliding plate (7) is arranged between the upper support base plate (4) and the middle lining plate (5) in cylindrical fit; a plane sliding plate (8) is arranged between the middle lining plate (5) and the lower support base plate (6); the saddle bow (1) is fixed on the upper support base plate (4); and the lower support base plate (6) is fixed on the pad stone (3). The invention overcomes the defects of the traditional saddle through the design of the saddle bow supporting structure, thereby having the characteristics of safety and reliability, flexible rotation, rational stress spread, convenient regulation and convenient maintenance.
Description
Technical field
The invention belongs to the bridge technology field, relate to a kind of dispersed cable saddle structure that is used for bridge concretely.
Background technology
At present, traditional dispersed cable saddle is shown in Fig. 3,4,5: comprise that mainly saddlebow 10, cross section are saddle body 11, the base 12 of inverted triangle, saddlebow 10 is welded on saddle body 11 upper ends, last contiguous block 13 and lower connecting block 14 by strip between saddle body 11 and the base 12 are connected, also be provided with rotational pin between last contiguous block 13 and the lower connecting block 14, form linear contact surface between saddle body 11 and the last contiguous block 13, this structure adopts the combination construction of casting-weldering combination, the saddlebow part is cast with cast steel, and saddle is welded into by steel plate.The structure of dispersed cable saddle mainly adopts cambered surface steel contact surface to realize that its rotational angle is little, and the rotation and the difficulty of sliding are being rotated the shortage that manifests on flexibility, the slidable adjustment, and the rotation slip resistance is big, and behind the very difficult rope that guarantees to loose, the rope stress distribution of loosing is even.Above-mentioned line contact surface, the contact radian is fragile, causes the dispersed cable saddle disabler, and simultaneously it adopts the line contact, and it is big to pass to concrete stress, needs that board size is thick down could guarantee concrete stress.In addition, be subjected to the restriction of saddle shape structure, saddle height degree is big under the prerequisite that stressed distribution is required, and the whole saddle height that is is than higher, and the center of gravity high stability is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of safe, reliable, rotate flexibly, the stress diffusion is reasonable, easy to adjust, maintaining is used for the dispersed cable saddle structure of bridge easily.
Technical scheme of the present invention is as follows:
A kind of dispersed cable saddle structure that is used for bridge, saddlebow, saddle assembly and pinner, described saddlebow is supported on the described pinner by described saddle assembly, described saddle assembly comprises upper bracket plate, middle liner plate and lower support plate, forming cylinder between described upper bracket plate and the middle liner plate cooperates and is provided with the cylinder slide plate between the two, be provided with the plane slide plate between liner plate and the lower support plate in the middle of described, described saddlebow is fixed on the described upper bracket plate, and described lower support plate is fixed on the described pinner.
Adopt said structure, key is that the supporting between saddlebow and pinner adopted a kind of brand-new structure and Principles of Regulation, cooperate by the sphere between upper bracket plate, the middle liner plate and to realize rotating, improve traditional dispersed cable saddle with the cylinder contact and adopt the line contact surface, the contact radian is fragile, causes the dispersed cable saddle disabler, and it adopts the line contact simultaneously, it is big to pass to concrete stress, needs the thick defective that could guarantee concrete stress of board size down.It is big and rotate flexibly that the contact of the sphere that adopts in this structure has a rotational angle, and more traditional dispersed cable saddle structure volume is little easy to adjust and improve supporting capacity, and the rope stress distribution of loosing is even.Realize the slip of displacement by the plane slide plate that is provided with between middle liner plate and the lower support plate, with rotate and slide be separated into 2 parts fully, solve traditional dispersed cable saddle slide the shortage that manifests on difficulty, the slidable adjustment, rotate the big defective of slip resistance.In addition, adopt fully independently saddlebow, saddle assembly and pinner formation in this structure, especially saddlebow can be dismantled from the saddle assembly, is convenient to maintaining like this.
Described pinner is embedded in the pre-buried crab-bolt that is furnished with down, and this crab-bolt upper end is connected with steel plate, and described lower support plate is fixed on the described steel plate.
This structure is easy for installation, embedding in advance pre-embedded steel slab and following crab-bolt on the Sarasota pinner, and lower support plate couples together by bolt and pre-embedded steel slab, and saddlebow also is connected by bolt with the upper bracket plate.All connect by bolt, not only installation, easy to adjust, and also maintaining is more convenient.
Described cylinder slide plate and plane slide plate adopt polyethylene to make.
Beneficial effect: the present invention has overcome the defective that traditional saddle exists by to the design of saddlebow supporting construction, have safety, reliable, rotate flexibly, the stress diffusion is reasonable, easy to adjust, maintaining is characteristics easily.
