Installation of stair guard
In recent years, the real estate market has seen a lot of leaping storey houses, which make the interior stairs appear in the room. The design of stairs and the safety of guardrails become a key point of interior decoration.
As the protective facilities of stairs, the protective fence is not only the decoration function, but also the safety function, which is often ignored by people. In order to achieve the decorative effect in home decoration, sometimes the spacing between railings is too large, and the height of railings does not meet the standard. At the end of the day, young children are not considered, and their judgment ability is poor, so they will use railings to climb and climb. This leaves a hidden danger of insecurity.
In order to ensure the safety function of guardrail, the following aspects shall be paid attention to during construction:
(L) the guardrail must be installed firmly without looseness.
(2) the height of the guardrail is determined according to the gradient of the escalator. Generally, the step is about 900mm upward. If the gradient is greater than 33 (12 ", the height of the handrail shall be greater than 90mm.
(3) the distance between railings should not be more than 130 to avoid children from drilling and falling from railings.
(4) the handrail shall be set to avoid children climbing on the high.
The height and width of each step of the same stair should be the same, and the size should not change irregularly, so as to ensure the constant relationship between slope and step.
The width of the ladder section is generally determined by the flow of people, and the principle is to ensure smooth passage. Generally, the width of single access ladder shall be 800-900mm; the width of double access ladder shall be 1100mm-1400mm; the width of three access ladder shall be 1650-2100. If more people flow through, the width of each flow shall be increased by 550 + (0-150) mm. When the width of the stair section is more than 1400mm, the handrail against the wall shall be set generally, and when the number of people on the stair exceeds 4-5, the middle handrail shall be set generally.
