Opening type steel dual protection assembly type railing

Abstract

The invention provides an opening type steel dual protection assembly type railing, which comprises railing pieces, wherein the railing pieces are formed into a whole by a plurality of vertical railings ranged at equal intervals and a plurality of transverse railings vertically connected with the vertical railings, both sides of the railing pieces are respectively connected with upright posts, the upright posts are fixedly arranged on a base, the cross sections of the vertical railings and the transverse railings in the railing pieces are respectively in an opening shape, the transverse railings and the vertical railings are connected through stainless steel straight rivets or stainless steel U-shaped rivets, both sides of the railing pieces are connected with the upright posts through connecting elements, and the outer surfaces of the vertical railings, the transverse railings, the connecting element and the steel posts are respectively provided with low-potential metal first protection layers and antioxidation nonmetal second protection layers capable of forming compact oxidation films or passivation films. The opening type steel dual protection assembly type railing has the effects that the structure of the railing is simple, the manufacture is easy, the intensity is high, the cost is low, the service life is long, the technology is mature, materials are easy to obtain, and the cost performance is much higher than that of any other railing. When being widely popularized and used, the opening type steel dual protection assembly type railing has the positive effect on the safety protection, energy saving, consumption reduction and carbon discharge reduction.

Description

technical field [0001] The invention relates to an open-shaped steel double-protection assembled fence. Background technique [0002] Many outdoor facilities on the ground need walls or fences for isolation and protection. However, the enclosure wall lacks permeability, which affects the landscape and has a greater impact on the environment. The direct environmental impact is that it is not ventilated and light-proof. Therefore, many cities have carried out activities to tear down walls and reveal greenery many years ago. But after the wall is demolished, it is necessary to prevent unrelated people from approaching, and the way is to add fences. In my country, except for rural vegetable gardens, orchards, pastures and many other easily damaged fences and barbed wire woven and tied with plant orange stalks, the total length of fences that are assembled and manufactured in factories in use is more than 500,000 Km. Railways, non-underground parts of subways, high-grade highw...

AI Technical Summary

Problems solved by technology

The construction party cannot bear the unit price

[0005] 2. The steel wire of the steel wire mesh fence is easy to be cut, and it is mostly used in towns or units, and it is easy to be damaged by people in the outer suburbs.

[0006] 3. Stainless steel fence is not easy to rust, and it is also very beautiful to make, but the cost is too high, and the residual value after damage is relatively large (easy to be stolen and destroyed by criminals), so it is not suitable for large-scale suburban projects

[0007] 4. Cast iron fences are too brittle and have poor impact resistance. If the section is small, the strength is not enough, and if the section is large, the cost is high

[0008] 5. Plastic steel fence, the plastic parts are easy to age and be damaged, and the inner lining steel is easy to rust

[0009] 6. Bamboo and wood fences need to cut down trees, which are easy to rot under the influence of wind, rain and sunlight

If the minimum cross-section is used for the fence components, since the fence has a certain height and is used in the outdoor space above the ground, it is very easy to age under the effects of wind and rain loads, temperature change loads, and acid medium erosion, and the glossy surface disappears prematurely, and horizontal and longitudinal cracks appear. , The phenomenon of steel bar exposure

Not only affects the landscape, but also easily damaged
