Problems solved by technology

The prefabricated fence is made of several steel pipes assembled and plugged together. The prefabricated fence has the advantages of high strength and is not easy to deform. However, the steel pipe adopts a square structure, and the edges and corners are easy to scratch the human body, and there are also disadvantages such as less color change and lack of movement. , and the iron connecting parts need to be welded, easy to rust, and the processing cycle is long. This kind of guardrail has gradually faded out of the market

Abstract

The invention discloses a spraying type steel barrier, which comprises columns, upper cross bars, lower cross bars and vertical bars. The main bodies of the columns, the upper cross bars, the lower cross bars and the vertical bars are all integrated style steel works. The columns are made from the galvanized steel strip, made into steel pipe of a certain shape and sprayed with plastic or paint; the upper cross bars, the lower cross bars and the vertical bars are integrated parts which the upper cross bars, the lower cross bars and the vertical bars are respectively made from the galvanized steel strip, steel pipes of a certain shape are made through extrusion forming of the steel pipe stock mould, seam welding of the high frequency induction welder and extrusion forming of the steel pipe shaping mould and the integrated parts are formed by placing the vertical bars between the upper cross bars and the lower cross bars, welding and fixing, and at last spraying plastic or paint on the exterior surface of the integrated parts. The spraying type steel barrier has the advantages of high structural strength, deformation resistance, beautiful and clean barrier surface, rustiness resistance, easy cleaning, greatly reduced maintenance cost, both the beautiful appearance of the PVC plastic steel barrier and the high strength of the assembly type barrier.

Description

technical field [0001] The invention relates to a guardrail, in particular to a spray-painted steel guardrail. Background technique [0002] At present, there are mainly two types of guardrails: PVC plastic steel guardrails and fabricated fences. PVC plastic-steel guardrail is made of PVC plastic material, and then some steel pipes are inserted inside to increase the strength. PVC plastic-steel guardrail has the advantages of smooth surface, easy to clean, dynamic, and many color changes, but its strength is not high enough, easy to aging and deformation, etc. Disadvantages, and the plastic connectors are easy to crack. The reflective film on the PVC plastic-steel guardrail is a plastic block that can be inserted into the vertical pole. The prefabricated fence is made of several steel pipes assembled and plugged together. The prefabricated fence has the advantages of high strength and is not easy to deform. However, the steel pipe adopts a square structure, and the edges a...
