Abstract
The utility model relates to a zinc-aluminium-alloy-plated scaffold steel pipe. The zinc-aluminium-alloy-plated scaffold steel pipe comprises a steel pipe body, a zinc-plated layer is formed on the steel pipe body, and a zinc-aluminium alloy layer and an aluminium metal layer are also formed between the zinc-plated layer and the steel pipe body. The zinc-aluminium-alloy-plated scaffold steel pipe provided by the utility model has longer service life and high corrosion resistance, a mark can be more conveniently punched on the steel pipe, and related information can be noted.
Description
Technical field
The utility model relates to a kind of scaffolding steel pipe, especially relates to a kind of zinc-plated scaffolding steel pipe.
Background technology
Scaffold (scaffold) refers to that the job site is operated and solve vertical for the workman and level is transported the support of setting up.Mainly work up and down for the constructor or purposes such as maintenance of peripheral safety net and high-altitude installation component, the scaffold manufacturing materials has usually: bamboo and wood, steel pipe or synthetic materials etc.At present, coating steel pipe is the most frequently used material.
Coating steel pipe divides two kinds of galvanizing and electrogalvanizings, and the electrogalvanizing capital is low, and appearance is not very lubricated, and the erosion resisting of himself differs a lot of than hot dip galvanizing pipe.Hot-dip galvanized bed thickness, it is average to have coating, attach exert oneself strong, strong points such as the utilization life-span is long.Yet, comprise and adopt the existing zinc-plated scaffolding steel pipe of hot dip galvanizing process still to exist some problems, the one, its application life and decay resistance are still not high enough; Existing besides coating steel pipe hardness is higher, and inconvenience is beaten blaze note above that, indicates some relevant information, like application life of manufacturer, date of manufacture and safety etc., exists some potential safety hazards.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of zinc-plated aluminium alloys scaffolding steel pipe with higher application life and stronger decay resistance is provided.
Second purpose of the utility model is to provide a kind of blaze of on steel pipe, beating that can be more convenient to remember, indicates the zinc-plated aluminium alloys scaffolding steel pipe of relevant information.
For achieving the above object, the technical scheme of the utility model is:
A kind of zinc-plated aluminium alloys scaffolding steel pipe comprises the steel pipe body, on the steel pipe body, is formed with zinc coat, between zinc coat and steel pipe body, also is formed with one deck allumen layer and layer of aluminum metal level.
According to the further setting to technique scheme, said zinc coat, allumen layer and aluminum metal layer all have on the inner and outer wall of steel pipe.
Preferably, the thickness of steel pipe tube wall is between 3.2 ~ 3.8 millimeters.
The positive progressive effect of the utility model is to have higher application life and stronger decay resistance, and the blaze of on steel pipe, beating that can be more convenient is remembered dated relevant information.
Description of drawings:
Fig. 1 is the cross-sectional schematic of the utility model product structure;
Fig. 2 is the utility model coating structure sketch map;
Fig. 3 plays the sketch map of information such as being carved with literal, letter for the utility model product surface.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment present embodiment is described further.
See figures.1.and.2:
A kind of preferred real-time mode of a kind of zinc-plated aluminium alloys scaffolding steel pipe of the utility model; Comprise steel pipe body 10; 10 are formed with coating 20 on the steel pipe body, and coating 20 constitutes by three layers, are respectively to be positioned at outermost zinc coat 23; Be positioned at aluminum metal layer 21 that the inside contacts with the steel pipe body and the allumen layer 22 that is positioned at the centre.The thickness of steel pipe tube wall is between 3.2 ~ 3.8 millimeters.With reference to Fig. 3, because aluminum metal is the soft metal, the hardness of allumen is also relatively low; The utility model can engrave mark easily on steel pipe; Indicate some relevant information,, be convenient to identification and warning in application life like application life of manufacturer, date of manufacture and safety etc.
The zinc-plated employing hot dip galvanizing process of the utility model, it is average to have coating, attach exert oneself strong, strong points such as the utilization life-span is long.
Claims (3)
1. a zinc-plated aluminium alloys scaffolding steel pipe comprises the steel pipe body, on the steel pipe body, is formed with zinc coat, it is characterized in that, between zinc coat and steel pipe body, also is formed with one deck allumen layer and layer of aluminum metal level.
2. zinc-plated aluminium alloys scaffolding steel pipe as claimed in claim 1 is characterized in that said zinc coat, allumen layer and aluminum metal layer all have on the inner and outer wall of steel pipe.
