Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A bridge wind-resistant high-damping alloy saddle is shown in figure 1 and comprises

And the bottom plate 1 is positioned at the bottom of the saddle. The saddle body 2 is fixed at the top of the bottom plate 1, the L-shaped plates 3 are respectively arranged on two sides of the saddle body 2, each L-shaped plate 3 comprises a vertical plate and a bottom side plate, and the bottom side plates are fixed on the bottom plate 1. Still have first deep bead 4 on the bottom side board of two L templates 3 respectively sliding connection, the vertical setting of first deep bead 4 just is located the outside of the vertical board of corresponding L template 3. The saddle further comprises a high damping shock absorber 7 arranged between the vertical plate of the L-shaped plate 3 and the corresponding first wind deflector 4. When using this alloy saddle, at first install saddle body 2 at the top of bridge tower, because its mounted position is higher, when it receives wind-force, first deep bead 4 blocks wind-force, simultaneously when it receives blowing back of wind-force, can slide on L template 3, and under the effect of high damping bumper shock absorber 7, cushions the wind-force that first deep bead 4 received, consequently reinforcing saddle body 2's anti-wind effect.

In an alternative embodiment, the inner side of the first wind deflector 4 is provided with a reinforcing support plate 6, which is arranged approximately parallel to the first wind deflector 4, for enhancing the wind resistance of the first wind deflector.

In an alternative embodiment, as shown in fig. 3, one end of the high damping shock absorber 7 is fixed on the reinforced support plate 6, and the other end is fixedly connected with the vertical plate of the L-shaped plate 3. High damping bumper shock absorber 7 can be equipped with a plurality ofly, and the equidistance is fixed strengthen between backup pad 6 and the vertical board of L template 3.

In an alternative embodiment, the saddle further comprises a second wind deflector 5 fixed on top of the first wind deflector 4, the second wind deflector 5 being arc-shaped and bent towards the saddle body 2 for deflecting the wind from the top position of the saddle body. Design into the arc with the second deep bead, it is excessive that the side deep bead of saddle body has the arc to the top deep bead promptly, avoids the right angle design to reinforcing deep bead anti-wind ability.

In an alternative embodiment, as shown in fig. 2, fan-shaped reinforcing ribs 8 are fixed on both sides of the saddle body 2, and play a role in enhancing the strength and rigidity of the saddle body 2.

An optional implementation mode, both ends of two first baffles are all fixed with third baffle 9, third baffle 9 is the arc, and crooked direction is towards saddle body 2 for keep out the wind to saddle body 2's both ends. Alternatively, the third baffle 9 may be configured as an arc-shaped hollow structure, which includes a flat inner wall and an arc-shaped outer wall, and the interior of the third baffle is hollow. The flat inner wall can enhance the stability of the third baffle 9, and the hollow structure can reduce the weight of the whole structure. Similarly, the third baffle 9 is designed into an arc shape, namely the side wind shield of the saddle body is connected with the left end baffle and the right end baffle in an arc shape, so that the right-angle design is avoided, and the wind resistance of the wind shield is enhanced. The first wind deflector 4, the second wind deflector 5 and the third wind deflector 9 are combined to form a coating for the saddle body, so that wind power is blocked.

In an alternative embodiment, in order to realize the movement of the first wind deflector 4 so as to buffer the received wind force, sliding grooves 10 are equidistantly formed in the bottom side plate of the L-shaped plate 3, and a sliding block 11 adapted to the sliding grooves 10 is arranged at the bottom of the first wind deflector 4. Optionally, the sliding groove may be a T-shaped groove, and the sliding block may be a T-shaped block adapted to the T-shaped groove.

In an alternative embodiment, the bottom plate 1 is provided with a plurality of mounting holes 12 for mounting the saddle on the top of the bridge tower.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
