There is a hole under the small column and a wooden wedge is added. This is the connector connecting the tile and the wooden column. Apply glue when installing.

The step height should not be greater than 17.5cm, while the step height of residential buildings should be less than 20cm, and the error of step height should not be greater than 1 cm.

2. Before installing wooden stair handrails, check and measure them first. Check whether the flat steel fixing the wooden handrail is smooth and firm, then drill small holes in the flat steel to fix the wooden screws, and then brush the antirust paint; If it is measured, it is necessary to measure the length of wooden handrails between each staircase with a tape measure, so as to accurately cut the material, and it is necessary to add a little length on the basis of measuring the size. For the splicing of wooden handrails, a special tenoning machine shall be used to tenon fingers, and there shall be no more than one tenon joint on each step.
