本实用新型公开了一种抗风减振栏杆，包括栏杆，该栏杆上固定有水平布置的扶手条，其特征在于：所述扶手条的横截面为条形，该条形横截面与水平线的夹角为15～45度，且该条形横截面的高端位于所述栏杆外侧，低端位于所述栏杆内侧。其显著效果是：结构简单，安装制作方便，成本低廉，气流引导作用明显，桥梁所受涡激共振振幅显著降低，大幅降低了气流对桥面冲击所产生的振动，提高了桥梁的抗振性，提高了桥梁的使用寿命。
The utility model discloses a wind-resistant and vibration-reducing railing, which comprises a railing on which horizontally arranged handrails are fixed, and is characterized in that: the cross-section of the handrail is strip-shaped, and the cross-section of the strip is the same as the horizontal line. The included angle is 15-45 degrees, and the high end of the bar-shaped cross section is located outside the railing, and the low end is located inside the railing. Its remarkable effects are: simple structure, convenient installation and manufacture, low cost, obvious airflow guiding effect, significantly reduced amplitude of vortex-induced resonance on the bridge, greatly reducing the vibration caused by airflow impacting the bridge deck, and improving the vibration resistance of the bridge , improve the service life of the bridge.
Description
Technical field
The present invention is mainly used in the accommodation rail of bridge, particularly is a kind of wind resistance vibration damping railing.
Background technology
Achievement in research according to wind tunnel test and numerical value wind-tunnel, the influence that the shape of bridge outermost pedestrian guard rail swashs resonance to the bridge whirlpool is bigger, railing is good more to the guiding effect of air-flow, and the sharp resonance amplitude in the suffered whirlpool of bridge is low more, and the suffered harmful effect of bridge is also low more.Though at present the handrail of bridge outermost pedestrian guard rail mostly is strip, yet that its cross section mostly is is circular, square etc., the railing of these forms, or do not possess the air-flow guiding function, otherwise guiding function is very undesirable.Swash the harmful effect of resonance for alleviating the suffered whirlpool of bridge, the part bridge is installed facilities such as drainage plate in the bridge both sides, inconvenient but this kind measure is implemented, the cost height.
The remarkable shortcoming of prior art is: it is very undesirable not possess air-flow guiding function or guiding function, can't effectively reduce the suffered whirlpool of bridge and swash resonance amplitude, or implement inconvenience, cost height.
Summary of the invention
The purpose of this invention is to provide a kind of wind resistance vibration damping railing, the air-flow guiding function is obvious, and the suffered whirlpool of bridge is swashed resonance amplitude and significantly reduced, and implements conveniently, and is with low cost.
For achieving the above object, the invention provides a kind of wind resistance vibration damping railing, comprise railing, be fixed with the handrail bar of lateral arrangement on this railing, its key is: the angle of described handrail bar and horizontal plane is 15～45 degree, the cross section of this handrail bar is bar shaped, and the high-end described railing outside that is positioned at of this bar shaped cross section, and low side is positioned at described railing inboard.
The handrail bar in the railing outside is higher than the inboard, can the wind channeling conduct that blow from the bridge outside be sent to bridge floor in an orderly manner with wind, and blow over from bridge floor, has reduced air-flow and has swashed resonance effect in the whirlpool that bridge floor produces.Significantly reduce air-flow bridge floor has been impacted the vibration that is produced, improved the vibration resistance of bridge, the application life of having improved bridge.
Described handrail bar is fixed on the railing top, and railing supports described handrail bar, and its strong point is between the mid point and low side of described bar shaped cross section.
The windward side that is positioned at the outer side handrail bar of railing is wide more, its drainage effect is just good more, therefore, tries one's best the strong point of railing to the low side of handrail bar design at the handrail bar, but consider the balance needs of handrail bar self, can consider 1/3 place of strong point design at distance handrail bar low side.
Though the handrail bar is wide more, its water conservancy diversion effect is good more, and the handrail bar is wide more, and the heavy burden of railing is also big more, simultaneously, has also influenced the aesthetic of integral bridge, and therefore, the horizontal width that can consider the handrail bar is at 30～40 centimetres; In the bigger place of wind-force, can suitably increase the horizontal width of handrail bar, be not limited to 30～40 centimetres.
The handrail bar upper surface and the bottom surface that are positioned at the high-end place of described bar shaped cross section are arc convex surface.
The middle part of described bar shaped cross section is a rectangular block, and two ends are half elliptic.
Arc convex surface can be slowed down the impact force of air-flow to the handrail bar, simultaneously, and also better appearance.
Described handrail bar can be designed to solid, also can be designed to hollow.
Remarkable result of the present invention is: simple in structure, install easy to make, with low cost, the air-flow guiding function is obvious, and the suffered whirlpool of bridge is swashed resonance amplitude and significantly reduced, and has significantly reduced air-flow and bridge floor has been impacted the vibration that is produced, improve the vibration resistance of bridge, improved the application life of bridge.
Description of drawings
Fig. 1: structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1: a kind of wind resistance vibration damping railing, comprise railing 2, be fixed with the handrail bar 1 of lateral arrangement on this railing 2, handrail bar 1 main body extends in parallel along railing 2 and bridge floor, described handrail bar 1 self tilts, and making the handrail bar 1 and the angle of horizontal plane is 15～45 degree, and the cross section of this handrail bar 1 is bar shaped, and high-end described railing 2 outsides that are positioned at of this bar shaped cross section, low side is positioned at described railing 2 inboards.
Described handrail bar 1 is fixed on railing 2 tops, and railing 2 supports described handrail bar 1, and its strong point is between the mid point and low side of described bar shaped cross section.
Handrail bar 1 upper surface and the bottom surface that are positioned at the high-end place of described bar shaped cross section are arc convex surface.
The middle part of described bar shaped cross section is a rectangular block, and two ends are half elliptic.
Handrail bar 1 is 30 degree with horizontal angle a, and this angle opens laterally; This handrail bar 1 horizontal width is 35 centimetres; The strong point of described handrail bar 1 is positioned at 1/3 place apart from handrail bar 1 low side.
Test shows, resonance amplitude can be swashed in the suffered whirlpool of bridge and reduce 60% under+3 degree angle of attack β.
