Stair railings are part of the stairs. Every family with a staircase will be very concerned about the design of the stair railings. There are many types of stair railings, some magnificent, noble atmosphere, some simple and generous, elegant, full of literary atmosphere, you What kind of preference is it? The design and specification of the stair railings must be installed in accordance with the overall effect of the stairs and the family. Let me introduce the stair railings and other related knowledge to everyone.
Stair railing design
First, the design of staircase railings
As a link between the upper and lower floors, vertical transportation facilities such as stair railings, elevators, escalators, and ramps can be used. In buildings with elevators and escalators, stair railings must also be installed at the same time. The design of the balustrade should be sturdy, durable, safe and fireproof, in addition to the requirements for functional use and attractive appearance. The number of balustrades should have sufficient access width and meet the fire evacuation capacity; the position of balustrades should be easy to find and should have direct lighting and natural ventilation. The door between the balustrades shall be open to the direction of evacuation, and the bottom floor shall have a direct outward exit; when the bottom stair railings need to pass through the hall and reach the exit, the spacing between the balustrades of the balustrade shall not be greater than the fire evacuation distance.
Second, the design of staircase railings is various
According to the plane position and function requirements in the building, the stair railings can have a variety of floor layouts. The most commonly used stair railings in the building are double-run stair railings, also known as double-staircase stair railings. Stair railings generally consist of stair railings, rest platforms, and balustrades. One of the highlights of this type of house renovation is the stair railing, which is not only a connection between the "upper" and "lower" in the home, but also highlights the personality of the owner. At present, many houses are usually left with prefabricated blank stair railings when they are handed over, but they are often incongruous with the decoration of the entire house. The designer stated that the design of the balustrade in the residence should take into account three elements: space, material, and suitable crowd.
Third, public building stair railing design
The staircase railing is undoubtedly the most important and most impressive part of the building. It has the practicality of connecting the rooms on each floor and gives people a very dynamic feeling. Therefore, the stair railing has a prominent artistic power in the building. A well-designed stair railing is like a carved piece of art, which is practical and beautiful.
Stair railing calculation rules
Look at the balustrade of the balustrade, some of them are on the extension of the meter, some of them on the t. You need to look at the balustrade of the stairs, wooden railings/steel railings, stainless steel railings, etc. Look at your local calculation rules and you will understand.
Stair railing spacing
According to the Civil Construction Design Principles 6.6.3.4, the railings for houses, nurseries, kindergartens, primary and secondary schools, and children's and children's special events must adopt structures that prevent children from climbing. When vertical bars are used as the railing, the nets are The distance should not exceed 0.11m; (this is mandatory)
The Civil Construction Design Principles 6.6.3.5 stipulate that: Culture and entertainment buildings, commercial service buildings, sports buildings, landscape architecture and other places that allow children to enter the activities, when using vertical bars as railings, the net distance of the rods is also Should not be greater than 0.11m. ;(This is a non-mandatory clause)
Stair railing height
The height of the handrail of the balustrade refers to the vertical distance from the leading edge of the step to the top surface of the handrail. The height of the stair railings is related to the slope of the stairs and the requirements for the use of the stairs. Steep stairs, the height of the handrails are shorter, and the heights of the handrails can be slightly higher when the slopes are gentle. In the slope around 30 ° often use 900mm; children use the stairs is generally 600mm. For general indoor stairs ≥ 900mm, usually take l000mm. The length of the horizontal railing on the side of the ladder well is >500mm, its height is ≥1000mm, and the height of the outdoor stair railing is ≥1050mm.
Stair railing specifications
First, the number of stairs, location and stairwells should meet the requirements for ease of use and safe evacuation.
(2) In addition to the clear width of the bench, the width of the bench for the daily main traffic stairs shall be determined in accordance with the characteristics of the use of the building, except that the flow width per person is 0.55 + (0 - 0.15) m. It should not be less than two people.
Note: 0 ~ 0.15m is the swing of the human body during the journey, and the places where there are many public buildings and pedestrians should take the upper limit.
3. When the ladder section changes direction, the minimum width of the platform handrail shall not be less than the net width of the ladder section. When there is a need to move large items, it should be widened.
4. The pace of each stage should generally not exceed 18 levels, nor should it be less than 3 levels.
5. The net height at the upper and lower aisles of the landing shall not be less than 2m. The height of the bench should not be less than 2.20m. Note: The height of the bench is the vertical height between the amount of the stepping front edge (including the 0.30m beyond the leading edge of the lowest and highest stepping) and the lower edge of the straight upward protrusion.
6. Handrails should be provided on at least one side of the stairs. Handrails should be provided on both sides when the net width of the steps is up to three people. Intermediate handrails should be provided for up to four people.
7. The handrail height of the indoor staircase shall not be less than 0.90m from the leading edge of the step. When the horizontal handrail on the side of the stairwell exceeds 0.50m long, its height shall not be less than 1m.
VIII. There should be anti-skid measures at the leading edge.
9. Where there is a staircase with a net width of more than 0.20 m for stairs that children often use, safety measures must be taken.
10. The height ratio of staircases shall comply with the requirements of Table 4.2.1.
11. The height of the railing shall not be less than 1.05m, and the height of the railing of high-rise buildings shall be properly increased, but should not exceed 1.20m;
Twelve, railings should not be left empty at a height of 0.10m above the ground or roof;
Residential step height 0.18, minimum width 0.25
Kindergarten primary school stairs maximum height 0.15, minimum width 0.26
Cinemas, theaters, stadiums, shopping malls, hospitals, nursing homes, etc. Stairs, maximum height 0.16, minimum width 0.28
Stairs for other buildings, maximum height 0.17, minimum width 0.26
Editor's summary: There are many kinds of stair railings, some of which are made of wood to give the entire family a deep retro taste, and the durability is high. Some families use a stone design that is also very unique. Smooth, rich in nature, and some families are made of iron or stainless steel, creating a glittering, rich and elegant, but individuals are more concerned about the safety of this feature, and now the design of stair railings is constantly improving at the same time, security It is also very important.
