Abstract
The present invention discloses one kind of windproof damping stay fixture, and is especially one kind of windproof damping stay fixture for bridge stay of various kinds of bridge to resist wind, decrease vibration and avoid fatigue. The windproof damping stay fixture consists of stay, stay clip, pull rod, rubber ring, screw, cut and reverse thread. The pull rod with reverse thread regulates the interval of stay, eliminates the initial eccentricity of stay, changes the constraint condition, raises the vibration frequency and reduce vibration amplitude of stay, so as to reach the aims of resisting wind, decreasing vibration and avoiding fatigue. The present invention has simple design and convenient construction and may find wide application in building industry, especially bridge construction.
Description
Technical field the present invention relates to a kind of wind resistance vibration damping cord clip of bridge cable, more particularly, relate to a kind of cable stayed bridge, suspension bridge, isostructural wind resistance vibration damping of bowstring arch bridge of being particularly suitable for, for bridge cable wind resistance vibration damping, prevent that fatigue from providing new approach.
Background technology has the relevant report of shock absorber in the prior art, and application number 94117302.X disclosed " being mainly used in the sleeve that is rolled into of shock absorber " is made up of sleeve plate, groove, bossing.It adopts theory of mechanics, makes its sleeve that becomes shock absorber, the effective shock absorber of inreal formation.The present invention can adjust the drag-line spacing by the reverse thread of pull bar, has both eliminated the drag-line initial eccentricity, changes the constraints of drag-line again, improves its vibration frequency, reduces its amplitude, prevents fatigue, and is satisfactory for result.
Summary of the invention the objective of the invention is to utilize the reverse thread of pull bar to adjust the drag-line spacing, changes the constraints of drag-line, improves the feature of its vibration frequency, can play the wind resistance vibration damping, prevent tired purpose structures such as cable stayed bridge, suspension bridge, bowstring arch bridges.Simplicity of design, easy construction, be widely used.
In order to achieve the above object, the invention provides following technical scheme: design a kind of wind resistance vibration damping cord clip of bridge cable, comprise drag-line (1), cord clip (2), pull bar (3), rubber ring (4), bolt (5), otch (6), reverse thread (7) is formed.Cord clip (2) is made up of two semicircular ring: the semicircular ring of a semicircular ring and another band sleeve handle, adopt bolt (5) to connect; Two groups of cord clips (2) are cuff drag-line (1) respectively, the rubber ring (4) of pad protection earlier before the cuff, and the two ends sleeve is being connected by pull bar (3).Sleeve is there being reverse internal thread, and pull bar (3) has reverse external screw thread, is the spacing of adjusting drag-line (1) for convenience, and there is otch (6) at pull bar (3) middle part, is convenient when twisting pull bar (3) with spanner.
The present invention's technical scheme preferably is: drag-line (1) is little one group an of distance, as between single rope face (bifilar) cable stayed bridge bifilar, between every group of suspension rod of suspension bridge, between the two suspension rods of bowstring arch bridge, 0.3～3.0 meter of longitudinal pitch is more reasonable, gives full play to mechanical properties of materials.
Compared with prior art, utilization of the present invention is adjusted the drag-line spacing by the reverse thread of pull bar, has both eliminated the drag-line initial eccentricity, changes the constraints of drag-line again, improves its vibration frequency, reduces its amplitude, has reached the wind resistance vibration damping, has prevented tired purpose.Simplicity of design, easy construction especially have broad application prospects in the bridge construction field in building trade.
Be description of drawings of the present invention below the description of drawings:
Fig. 1 is a contour structures elevational schematic view of the present invention;
Fig. 2 is a contour structures generalized section of the present invention;
Among Fig. 1～Fig. 2, (1) is drag-line, and (2) are cord clips, and (3) are pull bars, and (4) are rubber rings, and (5) are bolts, and (6) are otch, and (7) are reverse threads.
By specific embodiment the present invention is carried out more detailed description below the specific embodiment:
With reference to Fig. 1～2, protected rubber ring (4) by the peripheral pad earlier of the drag-line of cuff (1); With two groups of cord clips (2) difference cuff drag-line (1), adopt bolt (5) to connect two semicircular ring of cord clip (2); Twist pull bar (3) with spanner, make the spacing of two drag-lines meet design load, do not have off-centre.
