The stairs are the passages that connect the floors. The composition of stairs according to materials can be divided into: wooden stairs, metal stairs, concrete stairs, brick stairs, etc. Because of their different materials, the performance of various stairs is not the same. Because the stairs of modern commercial buildings are generally designed and manufactured by construction companies, we usually do not touch it when we are decorating. The stairs we mentioned here mainly refer to the indoor stairs. For example, Duplex buildings or single-family villas, there will be the existence of indoor staircases, so we will discuss this article, mainly the interior stairs! 1, the type of staircase Wooden staircases are relatively easy to make and have many styles, but their durability is relatively poor, and walking around makes them easy to make noises. Therefore, it is generally used in places where walking is limited. The structure of the metal staircase is very light, the design is relatively beautiful, and the construction process is relatively simple and convenient, but its disadvantage is that the maintenance is very troublesome. The concrete staircase has the characteristics of strong and durable, good safety, and no walking noise. However, it has the disadvantages of complicated pouring process and long construction period. Brick staircases are more economical and durable, but their shapes are very rigid and cannot be used effectively. If it is divided according to form, the stairs can also be divided into: straight ladders, which are rarely used because they occupy too much space; arc ladders, which are only suitable for large duplex houses; ladders are also the majority The selection of duplex houses; spiral ladders are variants of ladders and are currently used in some villas. 2, the requirements of the stairs components Stairs should not only be strong, safe, and beautiful, but they should not make excessive noise when used. Especially in the dead of night, walking on the stairs and making loud noises can cause a lot of inconvenience to the family, and the noise of the stairs can The material of the tread board has a close relationship, so be sure to pay attention when selecting materials. Stairs are also made up of a variety of different materials, such as solid wood treads, which pass through the paint process. Many people easily overlook this point, but we must pay attention to this when choosing, not just choose the style of the stairs. Also pay attention to whether it is made of environmentally friendly materials and do not let the stairs evaporate harmful chemicals. The width of stair treads is generally not less than 25 cm. The height is preferably between 16 and 18 cm. The length is not less than 85 cm. Such stairs are comfortable to walk on, and they will not appear narrow. There is a clear direction in the stairs, so avoid the stairs at the entrance point directly to the bedroom area to avoid directing people's gaze to privacy. In addition to the stair treads, other parts of the stairs should be smooth and rounded, with no protruding, sharp-edged structure, so as to avoid accidental injury to the user, and the stairs of the stairs should also be rounded to avoid Injury the foot. If metal railings are used as the handrails for stairs, it is best to do some treatment on the surface of the metal so that even in winter, people will not feel cold and uncomfortable when they touch it. The handrail diameter of the stairs is generally 6 cm, so it will be very comfortable to support. The width of the railing of the stairs is 8 cm. This is to take into consideration that the child accidentally stuck his head in it. 3, the shape of the stairs Not only should the stairs be chosen, but also the way of installing the stairs should be chosen. Only the quick and convenient installation is the most popular choice for people. Moreover, this installation method can effectively reduce the noise and dust pollution during installation. In general, the position of the stairs gives people a feeling of darkness, so the design of the light source is very important, the brightness of the lights should be appropriate, too dark light is not conducive to people walking safely, if the light is too bright, it is prone to glare, so It is best to choose light that is soft and can achieve a certain level of clarity. The stairs are mainly composed of stressed curved beams, steps, handrails and railings. The main components are designed to be organically connected so that they can bear forces with each other, and various beautiful shapes can also be designed. If a wooden rotary ladder is designed, the force of each step board needs to be at both ends, one stress point is on the middle cylinder, and the other force point is on the handrail of Panlong. If it is a wooden rectangular staircase, the tread plate is forced on a diagonal beam in the middle, and the force on the tread plate is transmitted to the wall at one end, and the other end is transmitted to the handrail. If it is a glass pedal arc ladder, its main force is on the curved beam, and the railing plays the role of guardrail and decoration. There are also some stairs designed to be suspended from the overhead beams. There is also a single-beam cantilevered step staircase that transmits forces to the upper and lower beams. A brief understanding of the styling and mechanics of these stair designs is mainly for individuals. Make a reference when building the stairs. 4, handrails of stairs The key to the staircase is the design of the handrail. The design of the handrail is an important part of the assessment of the design of the stairs. Of course, there are many forms of handrails, but be sure to choose carefully and choose the style that suits your own stairs. If it is in accordance with the material, the stairs can be divided into: wood handrails, steel handrails, stainless steel handrails, copper handrails, stone handrails, etc., and railings matching the handrails can give people rhythm beauty and rhythm beauty, so most of the use of carved aluminum, wood, Stainless steel pipes and brass pipes are equipped with sandblasted glass. These materials can produce lively and decorative designs. Nowadays, in order to highlight their personality and temperament, many people still choose some expensive wooden and stone handrails. 5, the fence of the stairs If it is an indoor staircase, the height of its guardrail should generally be about 90 centimeters; if it is an outdoor stair, the height of the platform guardrail should generally be 110 to 120 centimeters. The material of the guardrail must meet the requirements. It is forbidden to use the steel bar with severe corrosion as the guardrail; the guardrail welding place should be full of welds, and the weld should be smooth around. The prefabricated grille also needs to be neatly arranged, with a smooth and smooth surface, and a splicing firm and beautiful appearance. The indoor fence is the most taboo to use mirror stainless steel or other silver shiny metal, the most ideal material is to use forged steel, followed by cast iron, once again wood, or porcelain. The ideal material for the outdoor staircase and platform guardrail is stone or mirror stainless steel. 80 Aftermarket Decoration Space Effect Drawing Stairs Stainless Steel Space Glass Decoration Glass Brick Villa Door Craft Glass Carving Carved Glass Glass Door Bedroom Small House Villa Villa Villa Bedroom Lamp The formal name of quincunx screw is iso10664 screw or hexagonal internal, also known as star socket screw.
