What are the styles of stairs? What is the size of stairs?
In daily life, many people like to design their own stairs. So how big is the size of the stairs? Might as well get to know me! What are the styles of stairs? 1. According to the material of stair handrails, it is divided into
1. solid wood staircase: The application scope of wooden stairs is limited because it can't prevent fire. There are two types: dark step and open step. The step embedded in the groove of the inclined beam of the stairs (also known as the stair side) is a hidden step type; Nailed on the diagonal beam triangle wood is open-step type. The surface of wooden stairs is anticorrosive with paint
2. Tieyi stairs:
Steel-wood stairs: The load-bearing components of steel stairs can be made of section steel, and the nodes of each component are generally bolted or welded. The surface of the component is rustproof with paint. Treads 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 beams. This kind of stairs is called combined stairs.
3. Wooden stairs: The steps of the stairs are made of wood. Wooden stairs give people natural characteristics, which are more suitable for rural style and make people feel a sense of intimacy!
4. Crystal stairs:
5. Rubber stairs: The steps of the stairs are rubber, so the stairs can not only prevent slipping, but also prevent static electricity. It is a very good choice of stairs! Second, according to the different styles of stairs
1. Straight-up type: the stairs go straight upstairs without going through the turntable and turning.
2. spiral staircase: spiral staircase is usually arranged around a single column with a circular plane. Its platform and steps are both fan-shaped planes, and the width of the inner side of the steps is very small, forming a steep slope, which makes it unsafe to walk and complicated in structure.
The rotating staircase saves space. Generally speaking, if the space is relatively small, the minimum size of the hole of the rotating staircase can be opened to 13*13MM or 14 * 11 mm. The current rotating staircase is also the central column rotating staircase, and its stress point is only.
3. Telescopic stairs: The stairs are made of high-strength cold-rolled carbon steel, which can bear up to 2KG of pressure. The stair joints are riveted by advanced riveting technology and special stainless steel 34 rivet, which has high riveting strength and very stable walking, and overcomes the disadvantages of poor shaking stability of similar products
4. Folding stairs: exquisite and beautiful in appearance, suitable for the top floor storage room and relatively narrow space of villas;
5. spiral staircase: it has strong expressive force and occupies little space. Suitable for any space. 18-degree spiral staircase is a kind of staircase construction method that can really save space. At present, most architectural designs adopt this kind of staircase. The feature of this style is that the shape can be changed according to the different rotation angles.
6. Corner staircase: The corner staircase gives 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 low floors;
9. Double-running stairs: the most common ones are double-running straight up, double-running zigzag, double-running folding (parallel), etc., which are suitable for general civil buildings and industrial buildings;
1. Three staircases: there are three-fold stairs, T-shaped stairs, split stairs, etc., which are mostly used in public buildings; Scissors stairs are composed of a pair of parallel ladders with two running in opposite directions, or a pair of spiral stairs with a circular plane, which are usually arranged around a single column. Its platform and step are both fan-shaped planes, and the width of the inner side of the step is very small, forming a steep slope, which is unsafe to walk and complicated in structure.
Because the spiral staircase saves space, if the space is relatively small, generally speaking, the opening of the indoor staircase can be opened to a minimum of 13*13MM or 14 * 11 mm. Now the spiral staircase is also the central column spiral staircase, and its stress point is only one, that is, the center stress point. This stair size structure causes the tread board to shake up and down if walking on the outside of the stairs. This is the shortcoming of all the central column rotary stairs, and the larger the radius of the stairs, the more severe the shaking. The bearing capacity of revolving stairs is generally 15KG to 2KG, in contrast, the bearing capacity of other finished steel and wood stairs is generally around 4KG.
There are also spiral stairs with no central column, which mainly rely on the double spiral beam under the step to support the load, or the railing of the stairs to support the load. Relatively speaking, the size of the spiral staircase without a central column is more complicated, and the staircase is subjected to a variety of combined forces such as bending, torsion, shearing and compression, which is complicated and difficult to calculate. The stress on the balustrade is more complicated in staircases without pillars, because the balustrade is generally narrow and the out-of-plane stability of the beam is difficult to control. Matters needing attention in the design of spiral staircase size first
In order to avoid illusion when going up and down stairs, the heights of the first step and the last step of stairs should be the same as those of other steps. If it is necessary to change, the size of the spiral staircase should be controlled within 4 cm, preferably not more than 2 cm ~3 cm. Second,
the height of the ceiling is the highest step of the indoor stairs, and there needs to be a clearance of more than two meters, and the minimum is not less than 1.8 meters, otherwise it will produce a sense of oppression. Third
railing spacing: the distance between the centers of two railings should be 8 cm, not more than 12.5 cm, so as to prevent children from sticking their heads out of the gap. Fourth
stair size: height of handrail: to waist position, 85 ~ 9cm, and the diameter of handrail is preferably 5.5cm.. Sixth, safety: stair parts should be smooth and round, without protruding or sharp parts. For families with children and old people, 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 treads, such as anti-skid strips, anti-skid pads and anti-skid grooves. Seventh
stair width: when one side is empty, the clear width is not less than 75cm; When there are walls on both sides, the clear width shall not be less than 9cm. Eighth
stair style: the stair design should be consistent with the decoration style when rotating the stair size. Ninth
stair lighting: too dark lighting is not conducive to walking safety, and too bright lighting is prone to glare. Therefore, the light on the stairs should be soft and clear. Tenth
stair noise problem: it is related to the connection of various parts of the pedal. When using it, excessive noise should not be generated, so as not to affect the rest of family members.
