Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] Such as figure 1 As shown, a high-strength lightweight foamed aluminum steel pipe includes a hollow steel pipe body 1, the wall thickness of the steel pipe body 1 is between 0.1-0.5cm, and the steel pipe body 1 is filled with foamed aluminum 2. The cross-section is made of foamed aluminum plate with a thickness of 1-3cm, which is squeezed into the steel pipe body 1 to enrich the inner space of the steel pipe body 1; the steel pipe with this structure is light in weight, not easy to bend and deform, and has good bearing capacity , the pressure on the steel pipe is absorbed by the foamed aluminum;

[0021] Aluminum foam is composed of the following components in parts by weight: 100 parts of aluminum powder, 5 parts of magnesium powder, 5 ...

Abstract

The invention provides a high-strength light foamed aluminium steel pipe, and relates to the technical field of building materials. The high-strength light foamed aluminium steel pipe comprises a hollow-out steel pipe main body. The wall thickness of the steel pipe main body ranges from 0.1 cm to 0.5 cm. The steel pipe main body is filled with foamed aluminum. The sectional area of the foamed aluminum is formed by a circular foamed aluminium plate. The thickness of the foamed aluminium plate ranges from 1 cm to 3 cm. The foamed aluminium plate is squeezed inside the steel pipe main body, so that the inner space of the steel pipe main body is full. The steel pipe adopting the structure has the advantages that the weight is light, bending deformation is not likely to occur, bearing capacity is good, and pressure bearing down on the steel tube can be absorbed by the foamed aluminum. The high-strength light foamed aluminium steel pipe has the advantages that the structure is simple, the design is novel, by changing the structure of a traditional steel pipe, the bearing capacity of the steel pipe is good, and the deformation is not likely to occur. In addition, the price of a foaming agent is cheap, so that the high-strength light foamed aluminium steel pipe is economical and effective, traditional preparation procedures are reduced, and the production cost is lowered. Due to the fact that the foaming agent has dual functions of thickening and foaming, the poriness of the foamed aluminum is increased.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength lightweight foamed aluminum steel pipe. Background technique [0002] Metal foam is a new type of material composed of a metal matrix and pores. Generally, metals have a dense polycrystalline structure, and the pores in it, such as shrinkage cavity, porosity, and pores, are treated as a kind of defect. When there are many defects, it will affect the performance of the material and even become a waste product. The metal foam just takes advantage of this defect of the material. When the number of such defects of the metal material reaches a certain level (and the porosity is 40-98%, the pore diameter is 0.5-6mm or more), it can be sacrificed at the expense of its strength. At the same time, it has obtained other superior properties such as heat, sound, energy absorption, light weight, etc., and has become a new type of structural functional material. ...
