Description

Technical Field

[0001] The utility model belongs to the technical field of angle steel columns, and in particular relates to a lower groove type rolling cage column. Background Art

[0002] Among all kinds of safety protection on the sides of railways and highways, the knife-barbed rolling cage is a very common anti-climbing solution. The column bracket is the main accessory of the knife-barbed rolling cage, which plays the role of fixing the knife-barbed rolling cage and the longitudinal reinforcement. The traditional method is to weld a metal hook on one side of the bracket and fix it with wire. However, the use of hooks alone is very likely to cause the hooks to fall due to human or large external forces because they are exposed to the outside, causing loopholes in railway safety protection. There is also a risk of falling off due to loose welding during transportation and placement. On the other hand, the use of wire bundling to fix the knife-barbed rolling cage and the longitudinal reinforcement will cause a certain degree of damage to the surface anti-corrosion galvanized layer, and it is a waste of manpower and materials, which greatly slows down the construction progress.

[0003] The utility model patent (application number CN201620996177.6; announcement number CN206174626U; announcement date 2017.05.17) discloses a new type of guardrail net, including a column, a protective net, a diagonal support column, a tension cable and a barbed wire rolling cage. The column stands on the ground, the protective net is fixedly connected to the column through a clip, the tension cable passes through the protective net and is fixedly connected to the column, and the barbed wire rolling cage is installed on the top of the protective net. It can be clearly seen from the figure of the utility model patent that the protective net (equivalent to the rolling cage) is leaning on the "Y"-shaped extension arm, and the barbed wire rolling cage is fixed to the "Y"-shaped extension arm through a buckle. This fixing method must stabilize and fix the barbed wire rolling cage through a buckle, which is not easy to install. In addition, the column with a hook used for the conventional installation of the knife barbed rolling cage does not consider too many factors of transportation and installation convenience, so there is a risk of the hook falling off and complicated installation during actual use.

[0004] Therefore, the market needs to develop a rolling cage column that fixes the column itself and facilitates the installation of the rolling cage. Utility Model Content

[0005] The purpose of the utility model is to provide a lower groove type angle steel column, aiming to solve the problem that the conventional column with hook used for installing the knife-barbed rolling cage in the prior art does not consider too many factors of convenient transportation and installation, so there is a risk of the hook falling off and complicated installation during actual use.
