Abstract
The utility model relates to the field of suspension bridge main cable PPWS construction and in particular to a shape retainer in strand erection in suspension bridge main cable PPWS construction. The shape retainer at least comprises a V type frame. The shape retainer is characterized in that: the inside V type frame is connected with inserting sheets at even intervals; each inserting sheet is vertical and is parallel to each other; the inserting sheets are inserted in the V type frame; the V type frame and the inserting sheets are fixedly connected with connecting bolts; and the inserting sheets are at regular intervals, wherein the distance between two adjacent inserting sheets is equal to the diameter of a fixed strand. With the device, after the erection of suspension bridge main cable strands, the regular hexagon arrangement of the strands and parallel between the strands are maintained, thus the quality of main cable erection is improved.
Description
Technical field
The utility model relates to main rope of suspension bridge PPWS construction field, the shape retainer during particularly main rope of suspension bridge PPWS construction strand sets up.
Background technology
Along with advancing by leaps and bounds of infrastructures such as highway in China traffic,, progressively become one of first-selected bridge type of striding river, passage over strait as the strongest suspension bridge of span ability.At home, main rope of suspension bridge generally is made up of to up to a hundred prefabricated parallel steel wire strands (PPWS) tens of, and the main push-towing rope of the completion of constructing requires to go up strand from structure and approaches the regular hexagon arrangement, and each strand is answered keeping parallelism.
In the main push-towing rope erection construction,, in follow-up strand traversing, sag adjustment process in place, might disturbance set up the strand of completion, cause the displacement of strand mutual extrusion, finally influence the requirement that is arranged in parallel between strand and steel wire for the strand that sets up completion.Thereby after main cable strand sets up some (being generally three rows), about 200m the isolation stopping means is set at interval, and be commonly called as strand shape retainer, guarantee the shape need that main cable strand is arranged.
Traditional shape retainer is divided into V-type retainer and inserted sheet retainer, arranged adjacent.Set up strand; Side to light and shady face exist the temperature difference to cause the reversing of main cable strand, multilayer strand mutual extrusion under the sunshine situation; Because factors such as inserted sheet retainer cross spacing scarce capacity, inserted sheet material insufficient rigidity cause the inserted sheet distortion, shape keeps effect undesirable.
Summary of the invention
The purpose of the utility model provides the shape holding device that sets up the back strand in a kind of PPWS construction main push-towing rope, and this device makes strand keep parallel between orthohexagonal arrangement and strand after the main rope of suspension bridge strand sets up, and the raising main push-towing rope sets up quality.
The utility model solves the technical scheme that its technical problem adopted: the shape retainer of a kind of main rope of suspension bridge PPWS construction strand in setting up is provided; Which comprises at least the V-type framework; It is characterized in that: evenly be connected with inserted sheet in the V-type framework at interval, all vertical vertical and distribution that is parallel to each other of each inserted sheet.
Described V-type framework and inserted sheet are for pegging graft.
Described V-type framework is fixedly connected through connecting bolt with inserted sheet.
The inserted sheet of described fixed interval, the distance between wherein adjacent two inserted sheets equal the diameter of the strand that will fix.
The v-angle of described V-type framework is 120 degree.
Upper end, the both sides of described V-type framework is connected with the V-type framework and connects high section through connecing high bolt.
Described V-type framework is the V-type steel frame that shaped steel is welded.
Described inserted sheet is a steel spring plate.
The beneficial effect of the utility model is owing to adopted the V-type framework, has increased the spacing ability of strand side direction; Adopt the on-deformable inserted sheet of high-carbon spring steel material in order to isolate strand simultaneously; Keep parallel between strand; Shape keeps effect relatively good, also can adopt the mode of grafting simultaneously between inserted sheet and the V-type framework, can adjust the inserted sheet height according to the increase that strand sets up the number of plies.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is further specified:
Fig. 1 is the structural representation of shape retainer.
Among the figure: 1, inserted sheet; 2, V-type framework; 3, connecting bolt; 4, connect high bolt; 5, the V-type framework connects high section; 6, strand.
The specific embodiment
Embodiment 1:
Shown in the structural representation of Fig. 1; This shape retainer mainly is made up of V-type framework 2; Evenly be connected with inserted sheet 1 in the V-type framework 2 at interval; V-type framework 2 is fixedly connected through connecting bolt 3 with inserted sheet 1, the wherein all vertical vertical and distribution that is parallel to each other of each inserted sheet 1 of fixed interval, the distance between wherein adjacent two inserted sheets 1 equal the diameter of the strand 6 that will fix.
Because the strand spread geometry is a regular hexagon or near regular hexagon, and answers keeping parallelism between each strand, so the v-angle of V-type framework 2 is 120 degree.
The basic process of implementing is: when strand 6 sets up 3～4 rows, V-type framework 2 is installed, inserted sheet 1 is installed simultaneously, adopt connecting bolt 3 with inserted sheet 1 and V-type steel frame 2 bolts, prevent inserted sheet 1 landing.Through V-type steel frame 2 and inserted sheet 1, make strand 6 each burst vertical array of having set up become row, satisfy parallel designing requirement.
Above-mentioned V-type framework 2 is V-type steel frames that shaped steel is welded, and can increase the spacing ability of strand side direction; Inserted sheet 1 is a steel spring plate, adopts the on-deformable inserted sheet of high-carbon spring steel material in order to isolate strand, keeps parallel between strand, and shape keeps effect relatively good.
Embodiment 2:
The structure of present embodiment and embodiment 1 is basic identical, and difference is that V-type framework 2 and inserted sheet 1 are grafting; Upper end, the both sides of V-type framework 2 is fixedly connected with the V-type framework and connects high section 5 through connecing high bolt 4.
In the work progress; When strand 6 when setting up 1/4～1/3; Utilization connects high bolt 4 and the high section of V-type steel framework bridge joint is connect gets on the V-type steel frame 2, the purpose that connects high section is set is when early stage, strand 6 set up to make things convenient for strand 6 traversing to design attitude by the traction decorating position; Continue to set up strand 6 numbers of plies when constantly increasing,, upwards touch V-type inserted sheet 1, make inserted sheet 1 highly satisfy the height of the strand 6 that isolation set up with hammer in inserted sheet 1 bottom because inserted sheet 1 adopts the mode of pegging graft.
