What are the styles of stairs? 1. According to the material of stair handrails, it can be divided into 1 and solid wood staircase: the application scope of wooden stairs is limited because it cannot prevent fire. There are two kinds of dark steps and bright steps. The steps embedded in the groove of the inclined beam of the stairs (also called stair side) are hidden steps; The triangular wood nailed to the inclined beam is open-frame. Anti-corrosion coating for wooden staircase surface
2, wrought iron stairs:
Steel-wood stairs: the load-bearing components of steel stairs can be made of steel, and the joints of each component are generally bolted or welded. The surface of this part is rustproof with paint. Pedals and platforms should be made of embossed or checkered steel plates to prevent slipping. In order to reduce noise and consider the decorative effect, elastic surface layer or concrete, stone and other surface layers can be laid on the steel pedal; You can also directly lay reinforced concrete or stone steps on the steel beam. This kind of stairs is called combination stairs.
3, wooden stairs: the steps of the stairs are wooden. Wooden stairs give people natural characteristics, which are more suitable for rural style and make people feel friendly!
4. Crystal stairs:
5, rubber stairs: the stairs are rubber, so the stairs can not only prevent slip, but also prevent static electricity. It is a very good choice for stairs!
Second, according to the different styles of stairs, 1, straight up: the stairs are straight up without going through the turntable and turning.
2. Spiral staircase: Spiral staircase is usually arranged around a single column in a circular plane. Its platform and steps are fan-shaped planes, and the width of the inner side of the steps is very small, forming a steep slope, which is unsafe to walk and complicated in structure.
Spiral stairs save space. If the space is relatively small, generally speaking, the minimum size of the hole of the spiral staircase can be opened to 1300* 1300MM, or1400 *1100mm. Now the spiral staircase is also a central column spiral staircase, and its stress point is only one, that is, the central stress point.
3. Telescopic staircase: The staircase is made of high-strength cold-rolled carbon steel, which can bear the maximum pressure of 200KG. The stair joint adopts advanced riveting technology and special stainless steel 304 rivet riveting, which has high riveting strength and very stable walking, and overcomes the shortcomings of poor shaking stability of similar products.
4, folding stairs: exquisite and beautiful appearance, suitable for the storage room on the top floor of the villa and the place with relatively narrow space;
5. Spiral staircase: Spiral staircase has strong expressive force and small occupied space. Suitable for any space. 180 degree spiral staircase is a real space-saving staircase structure. At present, most architectural designs adopt this kind of stairs. The feature of this style is that it can change its shape according to different rotation angles.
6, corner stairs: corner stairs give people good design inspiration!
7. Round stairs: The design of the stairs is round.
8. Running the stairs alone: Running the stairs alone is the simplest and suitable for buildings with lower floors;
9. Double running stairs: The most common ones are double running straight up, double running twists and turns, and double running half (parallel). , suitable for general civil buildings and industrial buildings;
10, three stairs: three-fold, T-shaped, split, etc., mostly used in public buildings; Scissors stairs are composed of a pair of parallel ladders, which have two opposite directions, or a pair of parallel ladders.
What is the size of the stairs? Spiral staircases are usually arranged around a single column with a circular plane. Its platform and steps are fan-shaped planes, and the width of the inner side of the steps is very small, forming a steep slope, which is unsafe to walk and complicated in structure.
Because spiral stairs save space, if the space is relatively small, generally speaking, the minimum opening of indoor stairs can be opened to 1300* 1300MM, or1400 *100mm. Now the spiral staircase is also a central column spiral staircase, and its stress point is only one, that is, the stair size structure causes the pedal to shake up and down when walking on the outside of the staircase. This is the disadvantage of all revolving stairs with central columns. The larger the radius of the stairs, the more severe the shaking. The load-bearing capacity of spiral stairs is generally 150KG to 200KG. In contrast, the load-bearing capacity of other finished steel-wood stairs is generally around 400KG.
There are spiral stairs with no central column, which mainly rely on the double spiral beam under the steps to support the load, or the railing of the stairs to support the load. Relatively speaking, the spiral staircase without central column is more complex in size, and the staircase is subjected to various combined forces such as bending, torsion, shearing and compression, which is complex and difficult to calculate. The stress of railings in columnless stairs is more complicated, because railings are generally narrow and the out-of-plane stability of beams is difficult to control.
Matters needing attention in spiral staircase size design First of all, in order to avoid illusion when going up and down stairs, the height of the first step and the last step of stairs should be the same as that of other steps. If it must be changed, the size of the spiral staircase should be controlled within 4 cm, preferably not more than 2 cm ~3 cm.
The height from the highest step of the second indoor staircase to the ceiling requires a clearance of more than two meters, and the minimum clearance is not less than 1.8 meters, otherwise it will produce a sense of oppression.
Distance between the third railings: the distance between the centers of the two railings is 8 cm, not more than 12.5 cm to prevent children from sticking their heads out of the gap.
The fourth stair size handrail height: to the waist position, 85~90 cm, and the handrail diameter is preferably 5.5 cm. Six, safety: the stairs should be smooth and round, there can be no protruding or sharp parts. For families with children and the elderly, the gradient of stairs should be slow, and the rotation angle of indoor stairs should not be too large; Anti-skid measures should be taken for stair tread, such as anti-skid strips, anti-skid pads and anti-skid grooves.
Width of the seventh staircase: when one side is empty, the clear width shall not be less than 75cm；; When there are walls on both sides, the clear width should not be less than 90cm.
Eighth stair style: when rotating the stair size, the stair design should be consistent with the decoration style.
Ninth staircase lighting: too dark lighting is not conducive to walking safety, too bright lighting is easy to produce glare. So the light on the stairs should be soft and clear.
The tenth stair noise problem: it is related to the connection of various parts of the pedal. Excessive noise is not allowed when using, so as not to affect the rest of the family.
