Abstract

The utility model relates to a metal net post type safety fence, which relates to a guard bar, particularly a net post type safety fence. The guard bar is composed of a net slice, a vertical post, and a connection board connecting the vertical post and the net slice, and the connection mode of the utility model is the same as the mode of the existing net post type fence. The upper and the lower beams of the fence are not conventional metal rods, but a cage type metal skeleton welded by a transverse metal rods which are folded by a plurality of ofmetal rods; the number of the polygonal metal rings is equal to the number of the sides of polygonal rings; the metal rings are arranged in equidistance, and the transverse rods are symmetrically distributed on the rings; therefore, the net has high lever rigid performance, and besides, the utility model has beautiful appearance and uneasy roll-over.

Description

Wire lath pillar safety barrier

The utility model relates to guardrail, relates in particular to net post formula safety barrier.

As everyone knows, net formula guardrail already by vast enterprises and institutions, gardens, family as guardrail or partition.In today that the market boom, vehicle increase sharply, the traffic administration difficulty strengthens, and the wire lath safety barrier more is widely used as main line of communication center line and cuts off the road surface guardrails of both sides with bustling district.Present wire lath pillar safety barrier, though the shape sample is various, its net sheet all be by at grade some verticals to the Metallic rod with horizontal be welded, net sheet like this, rigidity is lower in the horizontal direction, is easy to damage; For guaranteeing enough rigidity, the material usage of often having to increase.In addition, the vertical of present wire lath sheet is to Metallic rod, and its upper and lower end all becomes not only style dullness of sphere shape, and easily the person crosses by not obeying the rule then.

The purpose of the utility model is, improves the structure of wire lath pillar safety barrier, improving its level to rigidity, and improves moulding and security personnel's reliability.

The utility model is achieved in that

As wire lath pillar safety barrier in the past, this guardrail is also by the junction plate of wire lath sheet, column, connection net sheet and column, form at the pedestal of vertical columns.Its improvements are: this wire lath sheet (1) is the upper and lower crossbeam of the cage metallic framework (4) that is welded of the transverse metal bar (3) of using the polygon metal ring (2) that formed by several Metallic rod complications and radical to equate with polygon ring limit number as the net sheet; Described metal polygon ring be into equidistant arrangement, transverse bar is symmetrically distributed in metal ring week, the angle of cut of polygon metal ring and transverse bar is the complementary angle of road surface slope angle.Described net sheet (1) is to be clamped between two junction plates (6) or junction plate (6) and its liner plate (6 ') with securing member (5); Junction plate (6) is to be fixed on the column (8) with securing member (7), or is welded on the column.Described column (8) is to be fixed on pedestal or ground (9) with pre-buried via hole or fang bolt commonly used.Described column is four directions, six sides or garden shape hollow column.Its then be cement or metal.

Embodiment:

The our factory has pressed such scheme, has made the cage metallic framework made with prismatic, hexagonal metal ring and the transverse metal bar upper and lower beam as the net sheet, the remainder of net sheet with now use the net sheet identical.

Mechanical test shows: this safety net, its level doubles above to rigidity than existing net.In appearance, more attractive in appearance, generous than existing safety net.Because underbeam all is with corner angle on it, be not easy to cross, so security reliability is improved, safety has realized intended purposes.

Claims

1, a kind of wire lath pillar safety barrier, comprise with some verticals to wire lath sheet, column and the junction plate and the liner plate thereof that are welded with horizontal Metallic rod, it is characterized in that: be replaced in wire lath sheet upper and lower transverse metal bar, it is the cage metallic framework that transverse metal bar that the polygon metal ring that formed by Metallic rod bending and radical equate with polygon metal ring limit number is welded, described metal transverse bar, with the angle of cut of Metallic rod be the complementary angle of road surface slope angle; Polygon metal ring is into equidistant arrangement, and transverse bar is symmetrically distributed in metal ring week; Described column is four directions, positive six sides or circular hollow post, and whole wire lath sheet and several have the junction plate of through hole, and with the securing member connection, junction plate is by securing member or be weldingly fixed on the column; Column is fixed on the pedestal by pre-buried via hole, perhaps fixes on the ground with fang bolt.

2, according to the described wire lath pillar of claim 1 safety barrier, it is characterized in that: described with the junction plate that connects cage metallic framework and column, be plate shaped or its both ends or one end upwards bend inwards long, the knuckle of bending angle connecting portion on polygon metal ring, and on the folding rib, beat at through hole, thereafter liner plate equates with junction plate end knuckle, and on the folding rib, be equipped with corresponding through hole, the substrate of junction plate, its shape is identical with the junction plate end, and the net sheet is with between two junction plates of securing member clamping or junction plate and the liner plate.
