Description

[0002] The laboratory intends to study steel tube wood core filled columns, that is, filling mortar or concrete between the steel tube and the wood to replace the steel tube concrete column. The specific production steps are: place the wood in the center of the steel tube, manually fix the steel tube and the wood, and then grout from top to bottom, and vibrate during the pouring process to ensure uniform filling. Use wood, a renewable resource, to replace natural aggregates.

[0003] However, the following problems were found during the research:

[0004] 1. If the diameter of the wood is large, the gap between the steel pipe and the wood is very small. On the one hand, it is difficult to pour the mortar into the gap; on the other hand, the gap is too small to put the vibrator into the gap for vibration, and it is impossible to ensure that the mortar can completely fill the gap;

[0005] 2. Artificially fixing the position of the steel pipe and the wood cannot ensure that the wood is always in the center. The wood may have a large eccentricity, which will have a certain impact on the axial compression test to be carried out in the future;

[0006] 3. When grouting from top to bottom, the mortar cannot fill the gap between the steel pipe and the wood very well, and the gap in the lower part of the filling column will not be filled with mortar; or, even if the lower part of the component is completely filled with mortar, it is impossible to determine whether there are large bubbles in the mortar in the gap, which affects the subsequent experiments.
