If there is an error in the production and installation of the stair handrail in the building, it will affect the safety and appearance of the handrail. The reason is that many details of the handrail connection are often ignored by people.

The height of the stair handrail refers to the vertical height from the step or platform surface to the top surface of the handrail. The design height of the handrail refers to the height H of the handrail measured at the center point of each step, and the height of the handrail measured at any point in the first half of each step (distinguished from the direction of the upper floor) The armrest height H' is greater than H; on the contrary, the armrest height H measured at any point in the second half of the step is less than H. Only by distinguishing the difference between the design height of the handrail and the height of the handrail can correctly handle the method of the stair handrail node.

When designing the horizontal projection of the handrail from the edge of the rest platform. When it is less than half the width of the step, that is, B/2, the handrails of the stairs for the upper and lower steps should be connected obliquely at the platform section.
If the horizontal projection of the designed handrail in the platform section is at a distance e = B/2 from the edge of the rest platform, the handrails of the stairs running up and down should be connected horizontally in the rest platform section, and the height of the handrail is equal to H .
When the width of the platform is large, and the distance e > B/2 between the horizontal projection of the stair handrail in the platform section and the edge of the rest platform, the platform handrails at the position exceeding B/2 should be connected horizontally, and the height of the handrail is equal to H .

In order to be beautiful and practical, it is customary to level the height of the armrest in the flat step with the armrest of the rest platform. Find the starting point in the sprint climb section handrail. The same height as the platform armrest.
The distance from the edge of the first step of the sprint stair is d=B-e.
When the platform (as a first step, these two points are actually the same point on the same step, the height of the handrail at these two points is naturally equal.

The practical method of handrail connection of right-angle stairs is: take the H value for the height of the handrail at the corner point of the rest platform, and then set out the rest of the handrail. But the disadvantage of this method is that the height of the handrail measured by the center of each step is not equal, and the handrail is not parallel to the stair step. In this case, the only way to improve parallax is to gradually adjust the length of each handrail pole.
