Problems solved by technology

[0006] In order to overcome the shortcoming that the aluminum alloy tube is prone to local instability when it is alone under pressure; and in order to solve the problem that the wood column is under pressure due to longitudinal cracks to reduce the bearing capacity of the column, and the wood is easy to be attacked by insects, easy to corrode, and easy to burn. The invention aims to provide a wood-aluminum alloy tube composite column and its manufacturing method, which can suppress the cracking caused by the wooden column and the local instability of the aluminum alloy tube under pressure, and improve the bearing capacity of the wooden column and the aluminum alloy tube. and keeps the wooden posts free from pests, corrosion and flammability problems

preparation example Construction

[0040] A method for preparing a wood-aluminum alloy tube composite column, the specific manufacturing steps include the following:

[0041]1) Select the material type and cross-sectional size of the wooden column according to the design requirements, and carry out the defect inspection of the wood, and choose the wood with less defects for the small-sized composite column;

[0042] 2) Dry the formed wooden column and control its moisture content to not exceed the equilibrium moisture content of the environment. By controlling the moisture content of the wood, the composite column will not continue to shrink in the environment after being formed, which will affect the restraining effect of the aluminum alloy tube on the core wooden column. However, even if there is a tendency to absorb water and expand when encountering a water environment, due to the restraining effect of the aluminum alloy tube on the core column, no adverse consequences will be produced at this time.

[004...

Embodiment 1

[0049] The combined column of this embodiment is a circular section (such as figure 1 ), the aluminum alloy round tube 2 is used, the outer diameter of the tube is 220mm, the wall thickness of the tube is 5mm, the length of the tube is 3000mm, which is the same as the length of the column, and the aluminum alloy material is 6082-T4.

[0050] The core wooden column 1 has a length of 3000 mm, an outer diameter of 160 mm, and a gap of 30 mm between the wooden column and the aluminum alloy tube, which can be used for the construction of the self-compacting expansive cement mortar 3 used in the combined column of this embodiment.

[0051] The circular wooden column is preferably made of wood with few defects, and then the wooden column is dried to reduce the moisture content of the wood to below the environmental equilibrium moisture content. If the local environmental equilibrium moisture content is 17%, the moisture content of the wood cannot be controlled. exceed this value. Af...

Embodiment 2

[0056] The combined column of this embodiment is a square section (such as image 3 ), using aluminum alloy square tube 2, the outer length of the square tube is 120mm, the wall thickness of the tube is 3.5mm, the tube length is 1500mm the same as the column length, and the aluminum alloy material is 5083-H12.

[0057] The core wooden column 1 is square, the side length is 90 mm, the length of the wooden column is 1500, and the gap between the wooden column and the aluminum alloy tube is 15 mm.

[0058] The material selection and processing of the square wooden column are the same as in Example 1. However, in this embodiment, the structural glue 5 is used as the filling material, and there is no need to perform waterproof treatment on the surface of the wood.

[0059] Place the wooden column in the aluminum alloy tube, and place four wooden wedges in the gap between the aluminum alloy tube and the wooden column at both ends to maintain the relative position between the alumin...

Abstract

The invention discloses a wood-aluminum alloy tube combination column and a manufacturing method thereof. The wood-aluminum alloy tube combination column comprises a longitudinal extending aluminum alloy tube and a longitudinal extending wood column, wherein the aluminum alloy tube sleeves the wood column; a self-compaction binding material layer is arranged between an outer wall of the wood column and an inner wall of the aluminum alloy tube; the self-compaction binding material layer is used for fixedly connecting the wood column and the aluminum alloy tube into an integrated combination column. The wood-aluminum alloy tube combination column can restrain the cracking of the wood column under a pressing effect and the local buckling of the aluminum alloy tube under a pressing effect, can increase the bearing capacity of the wood column and the aluminum alloy tube and can prevent the wood column from the problems of insect pests, corrosions and inflammable.

Description
