Problems solved by technology

[0022] In order to solve the above-mentioned technical problems, the present invention proposes a double-layer flexible windproof net, which solves the problem that the windproof effect of the existing single-layer net structure is not good, the wind resistance of the existing columns is large, and the columns are easily damaged. The damage causes the windproof net to lose its function, and it cannot guarantee the safe operation of the vehicle under the harsh conditions of strong wind and strong wind

Embodiment 1

[0063] Refer to the attached figure 1 , the present invention discloses a double-layer flexible windproof net, comprising a column structure 14 and a net body structure 15 installed on the column structure 14, the column structure 14 is installed on a steel column foundation 13, and the steel column foundation 13 blocks along the area to be protected. The wind route is arranged at an interval of 5-12m, and an upper support rope 16 and a lower support rope 17 are connected between a plurality of column structures 14. The column structure 14 includes a rod body 9, and the rod body 9 is a tapered rod body structure with a small upper part and a larger lower part. The longitudinal section of the tapered rod body is an isosceles trapezoid, the upper bottom of the isosceles trapezoid is smaller than the lower bottom, and the cross section of the tapered rod body is a regular polygon; the mesh structure 15 is a two-layer structure, which is arranged in sequence along the wind directio...

Embodiment 2

[0067] On the basis of Example 1, the best implementation mode of the present invention is: the bottom end 11 of the tapered rod body is fixed on the steel column foundation 13, and the top end 10 of the tapered rod body is arranged obliquely toward the wind direction 8 . The inclination angle of the tapered rod body is 60-85 degrees. The diameter of the inscribed circle of the top 10 regular polygons of the tapered rod body is ∮80mm˜∮200 mm. The diameter of the inscribed circle of the regular polygon at the bottom end 11 of the tapered rod body is ∮200mm˜∮500 mm. The support net 2 is formed by a plurality of diamond-shaped grid units woven by steel wires or steel wire ropes, the diameter of the inscribed circle of the grid is ∮50 mm to ∮300 mm, and the diameter of the steel wires or steel wire ropes is ∮3 mm to ∮8 mm. The windproof net 1 is formed by a plurality of rhombic grid units woven by steel plates or steel wires, the diameter of the inscribed circle of the grid is ∮3...

Embodiment 3

[0069] Windproof net 1 is mainly composed of: conical steel column, flexible support protection net, small aperture blocking protection net, upper and lower support ropes 17, side stay ropes 18, back stay rope 19, anchor bolts and anchors 20, pull anchors and anchors, clips components etc. The layout is that the steel column foundation 13 is arranged at a distance of 5-10 meters along the direction of the wind-blocking route in the area to be protected (the specific distance is determined according to the wind speed of the protected area and the height to be protected). After the steel column foundation 13 is fabricated + install the steel column on the foundation Stand it up and hang the support rope on the steel column hanger. Install the upper side stay rope 18 and the back stay rope 19 and tighten up the steel column that needs to install the back stay rope 19 and the side stay rope 18. Hang the flexible support windproof net 1 on the support rope and sew them together, a...

Abstract

The invention discloses a double-layer flexible windproof net, which relates to the technical field of windproof nets and comprises column structures and a net structure mounted on the column structures. Each column structure comprises a member in a conical member structure big end down, the longitudinal section of each conical member is in the shape of an isosceles trapezoid, the top of the isosceles trapezoid is smaller than the base thereof, and the cross section of each conical member is regularly polygonal. The net structure includes two structures which are a windproof net and a support net respectively disposed along the wind direction. Each of the windproof net and the support net is composed of a plurality of mesh units. The diameter of an inscribed circle of each windproof net mesh unit is smaller than that of an inscribed circle of each support net mesh unit. The net structure is hooked on an upper support rope and a lower support rope. Using the double-layer flexible windproof net well solves the problems that the existing windproof net in a single-layer net structure is poor in wind proofing effect, existing columns have high wind resistance and are easy to break to disable the windproof net, and vehicle running safety under severe conditions, strong wind and storm, cannot be guaranteed.

Description

[0001] technical field [0002] The invention relates to the technical field of windproof nets, in particular to a double-layer flexible windproof net. Background technique [0003] Definition of wind damage: Usually the wind force reaches level 6 or above (instantaneous wind speed reaches 10.8m·s -1 Above) strong winds have an impact on transportation and are called strong winds. Winds with a wind force of level 8 or above (instantaneous wind speeds above 17.0m·s-1) and winds that seriously affect transportation are called gale. In addition to the impact on traffic facilities, strong wind mainly affects the safe transportation of different types of vehicles. The resulting closure of expressways, overturning of different types of vehicles, and wind erosion of roadbeds are called expressway wind damages. [0004] Definition of strong crosswind: When the instantaneous wind speed is above 15.0m·s-1, and the direction of the line is close to perpendicular to the main wind ...
