Abstract
The utility model discloses a spatial all-cast type main cable saddle for a suspension bridge. The main cable saddle comprises a saddle body, an upper bearing plate which is arranged at the bottom of the saddle body, a lower bearing plate and an embedded base grid, wherein two cable bearing grooves which are formed along the length direction of the saddle body are formed on the saddle body side by side; and each cable bearing groove is formed in a curved mode in the vertical direction of the saddle body and is also formed in a curved mode in the horizontal direction of the saddle body. Due to the formation of the two cable bearing grooves, cable strands of two main cables can be mounted simultaneously, so that the economization of the space of a tower top and the material of the saddle body is facilitated. In addition, each cable bearing groove is formed in the curved mode in the vertical direction of the saddle body and is also formed in the curved mode in the horizontal direction of the saddle body, so that the main cables can be tangential to the cable bearing grooves in all directions; and due to the adoption of the structure, the two main cables can be smoothly turned in the vertical direction and the transverse direction to form a special parallel spatial main cable shape, so that the main cable saddle meets the requirements of spatial main cable self-anchored suspension bridges for single column towers.
Description
Technical field
The utility model relates to the bridge technology field, refers to that particularly a kind of suspension bridge space casts the formula main cable saddle entirely.
Background technology
Main cable saddle is one of chief component of suspension bridge superstructure, is the permanent steel member at Sarasota top braces main push-towing rope, and it bears the huge vertical pressure of main push-towing rope, and with the vertical pressure Transmit evenly of main push-towing rope to Sarasota; Also play so that main push-towing rope is located smooth-going transition on the Sarasota top simultaneously the effect of the folding s tress when reducing main push-towing rope and crossing cat head.Production method according to main saddle is different, can be divided three classes: entirely cast formula, all welded type, cast welding combined type.Existing full casting formula main cable saddle is with saddlebow, saddle body and base plate as a monoblock cast out, completes through Overheating Treatment, machining again.Traditional main cable saddle generally only has one to hold the cable groove, and main push-towing rope is turned in perpendicular, is applicable to the suspension bridge of horizontal alignment.
But for only post tower space main push-towing rope self-anchored suspension bridge, because bridge tower is only pillar, the cat head limited space need to be placed two main push-towing ropes and the implementation space turns at cat head.Traditional main cable saddle can not be placed two main push-towing ropes simultaneously, if place two main push-towing ropes, just need two main cable saddles, this just needs larger space, the most important thing is that its space that can not realize main push-towing rope turns to, be difficult to satisfy the requirement of only post tower space main push-towing rope self-anchored suspension bridge.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of suspension bridge space that can adapt to only post tower space main push-towing rope self-anchored suspension bridge entirely to cast the formula main cable saddle.
For realizing this purpose, the designed suspension bridge space of the utility model casts the formula main cable saddle entirely, comprise the saddle body, be arranged on top deck, bottom deck and the pre-buried base grid of saddle body bottom, it is characterized in that: described saddle body is provided with along two of saddle body length direction layout and holds the cable groove, described two are held the cable groove for being arranged side by side, described every is held cable groove curved layout on the vertical direction of saddle body, described every is held cable groove also curved layout on the horizontal direction of saddle body, article one, hold the cable groove to the curving of saddle body, it is crooked to the opposite side of saddle body that another holds the cable groove.
Described saddle body is bolted to connection successively by leading portion saddle body, linkage section saddle body and back segment saddle body and forms.
Described every is held to be equipped with on the cable groove and holds cable groove pull bar and hold down gag.
Described top deck has bottom deck, and bottom deck has pre-buried base grid, in the described pre-buried base grid pre-buried screw thread steel pole is installed, and described top deck, bottom deck are connected with pre-buried base grid by pre-embedded bolt, and backing plate is fixed on the pre-embedded bolt.
Described every is held in the cable groove and is equipped with vertical baffle.
The end of described bottom deck is provided with reaction frame.
The end of described top deck is equipped with positive stop strip and positive stop strip bolt.
The utility model holds the cable groove by arranging two, and the strand of two main push-towing ropes can be installed simultaneously, is conducive to save cat head space and saddle body material.In addition, every is held cable groove curved layout on the vertical direction of saddle body, also curved layout on the horizontal direction of saddle body, tangent to guarantee the main push-towing rope all directions and to hold the cable groove, this structure can make two main push-towing ropes smoothly turn to vertical and horizontal the realization, it is linear to form distinctive parallel space main push-towing rope, thereby adapts to the needs of only post tower space main push-towing rope self-anchored suspension bridge.
