Description

TECHNICAL FIELD

[0002] In order to study the steel pipe wood core filled column, that is, to fill the mortar or concrete between the steel pipe and the wood to replace the steel pipe concrete column, the specific manufacturing steps are as follows: the wood is placed in the center of the steel pipe, the steel pipe and the wood are manually fixed, and then the grouting is carried out from top to bottom, and the vibration is carried out during the pouring process to ensure uniform filling. The wood, a renewable resource, is used to replace natural aggregate.

[0003] However, the following problems are found in the research process:

[0004] 1. If the diameter of the wood is large, the gap between the steel pipe and the wood is very small.
