Comparison of decoration of RC concrete, steel and wooden staircases
Stairs are architectural structures that connect the upper and lower spaces, including steps, handrails, and some also include treads. Step drawer storage, flip-top storage, etc. According to the stair decoration material, it can be divided into three types: steel staircase, RC concrete staircase and wooden staircase. Generally speaking, RC concrete staircase decoration is made of local steel. It has the longest construction period and the least change in shape, but the highest cost. It is mostly used in public spaces. Steel-frame staircases mainly made of steel frame materials are lightweight and easy to use in space. The shape of the medium staircase has the most changes, and the staircase decoration is also the fastest. It is simpler than the RC concrete staircase in the staircase decoration project. The wooden ladder is the most common in residences, and is most suitable for high-ceiling layouts. It can also be designed with a variety of storage and stair decoration as needed. The lowest cost, but it is not suitable for large stairs, and the structural bearing capacity and durability are slightly lower than the first two types of stairs.
? RC concrete stair decoration project
RC concrete stairs are widely used in various buildings and indoor and outdoor public spaces. The stair decoration uses basic mud work techniques, combining formwork, steel bars, Concrete, surface treated with tiles, stone, PVC or plastic flooring, can be said to be the most common type of stair decoration in buildings. Its reinforced structure plus cement pouring, as long as there are no problems during the construction process, its bearing capacity and service life will be the same. Far more than wood and steel staircases, they require the least maintenance, but occupy the largest space. Outdoor stairs should also pay attention to the problem that cement materials are prone to surface cracks under sunlight.
? Steel staircase decoration project
Steel staircase materials can be divided into stainless steel, iron or special metals. There are actually several variations of treads, namely full plate type and steel plate type. Or keel ladder, the budget cost of stair decoration varies with the design shape and material shape. The appearance of steel structure stairs is light, thin and solid. It does not need to take up too much space to meet the load-bearing requirements of stairs, and it has a thin and penetrating feel. It can also minimize the impact of lighting. In recent years, it has been widely used in high-ceiling buildings and mezzanine house spaces.
Wooden Staircase Decoration Project
Wooden stairs have the softest tread feel, and the warm shape is most suitable for indoor residences. However, the wood materials are different. During construction, it is necessary to confirm the thickness, load-bearing capacity and toughness of the wood itself. Good materials can be durable for a long time. Another advantage of wooden staircase decoration is that it is highly variable and can be used for various storages according to needs, or can be produced in various ways according to design creativity. Special shape.
? How to budget for stair decoration projects?
Especially for residents in buildings with mezzanines and mezzanine houses, special attention needs to be paid to this aspect during interior decoration. Generally speaking, stair work is a vertical up and down work, and the number of steps counts, so "stair steps" are used. "Quantity" is used to calculate the cost, and the materials used, difficulty of construction methods, etc. will also be evaluated. If the space is undergoing secondary construction, there will also be a certain cost to dismantle the old stairs that needs to be estimated. If you change the location, you have to calculate the cost of digging and filling the holes with mud.
? Important knowledge for stair decoration projects
Most staircases with solid wood as structural materials will have two forms: single keel and double keel. Although suspended stairs are beautiful to look at, they have the greatest safety concerns. Generally speaking, it is best to have the treads on one side connected to the wall to increase the strength and stability of the treads. Stair construction most often uses iron nails or nail guns to join, resulting in insufficient strength and damage. It is recommended that the thickness of the wooden handrails should not be less than 6cm, otherwise the depth of connection with the railing is too shallow and it is easy to detach and cause danger. In Feng Shui theory, odd numbers are Yang and even numbers are Yin, so the stairs in Yang houses should be odd numbers. The step height is usually 16-18cm and the depth is 25-30cm for comfortable walking.
? What is the optimal size for stair decoration?
a. A floor height of 4 meters 2 is most suitable for a multi-story space.
b. If 200 cm is the most suitable basic space height generally accepted by the general public, then deducting the common floor thickness (10 cm) and pipeline interlayer (10 cm), the upper and lower floors must be at least It needs to be 420 centimeters high to ensure that the upper and lower floors are high enough for an adult to stand naturally.
c. Generally, if a building with a height of 3.6 meters or 3.2 meters is to be built as a double storey, the height of the lower floor space that does not require climbing a ladder should be the main one. It is recommended to leave 200 centimeters for the height of the lower floor. If the upper floor does not have enough standing height, it can be used as a temporary guest room or storage. The sitting height of the human body is 88 to 92 centimeters, the thickness of the mattress is about 12 to 20 centimeters, and the maximum height when sitting on the bed is about 112 centimeters, which is still plenty.
d. The gradient of general stairs is usually between 20 and 45 degrees, and 30 degrees is the best for the most stress-free walking. According to regulations, the minimum depth of steps must be 24 cm, including the front and rear staggered areas of 2 cm each, and the height of steps must be less than 20 cm. In terms of actual pedaling experience, the best step height is 16 to 18.5 centimeters. If the width of the stairs is 110 to 140 centimeters, it can accommodate two people walking staggered. If the residential space is limited, the width can be reduced.
? Things to know when decorating stairs:
In mezzanine, double-floor or building-within-a-floor space, if the staircase is not in the right position, it is likely to be the most wasteful and unavoidable step. Structure, some stairs are located in the center of the layout, dividing the space into two, with insufficient depth on the left and right, making it difficult to use the space. The stairs close to the entrance can easily block the space, making the passage crowded. Unless the stairs near the window are specially designed to be suspended, they will also be a major killer of lighting.
? How to design the staircase decoration to save space?
In a multi-story space with a small square footage, one more large and heavy staircase is equivalent to two less rooms. The actual square footage used may be lower than the flat space, which is quite uneconomical. If it can be fully utilized By using the stair space, you can earn a lot of square footage. You might as well see how designers save space from the stair!
? The stair step storage wall makes good use of the vertical floor effect
The unique height difference in the multi-story design will make more use of vertical space for storage than a single-story flat house! Cleverly replacing the storage function with the wall beside the staircase can make the floor more fully used. Generally, the height of a multi-story building is 190 centimeters, and storage spaces of the same height can often be extended on the sides of the stairs. Install cabinets along the wall to increase storage capacity without blocking the flow of space.
? Ingenious storage ideas for the space under the stairs
Due to the height and width of the steps, the indoor staircase itself is a space-consuming volume. If you don’t want the stairs to look bulky and If you want to make good use of space, then clever use of the abnormal space within the structure has become the focus of space design. By embedding storage functions between the corners of the stairs and the wall, you can make full use of every inch of space.
? The location of the stairs determines the floor space utilization
Rather than placing the stairs in the middle to divide the space depth on both sides, planning the stairs at the far side of the space can best leave the main The most complete and spacious use area of ??life, the upper space also maintains a single and complete use floor area. Whether it is a bedroom, study room, storage space, etc., the integrated design without redundant cutting is more convenient for use.
