Re-examination of staircase types of duplex and villa and staircase of villa The first type is reinforced concrete staircase, which is also the most common staircase form. Reinforced concrete stairs are all made by shuttering, binding steel bars and pouring concrete when the building is the main body. In other words, we can see that the reinforced concrete stairs in villas and duplex buildings were completed before the renovation. The second type of stairs and villas for the second interview are post-produced. In other words, after we got the house, there were no stairs in the room, but a simple staircase was built. At this time, it is necessary to redesign the overall structure of stairs and make good materials for installing indoor stairs. The first common material is the reinforced concrete stairs mentioned above. This kind of stairs is made of formwork, steel bars and concrete. The second common indoor staircase is the steel staircase. Steel staircase is a kind of staircase welded by steel structure in the later period, mainly made of square steel. The third kind of common indoor stairs is wooden stairs. Wooden stairs appear in some high-end villas, and now the utilization rate is getting higher and higher. As a result, the whole staircase is made of wood. What are the materials for stair treads? The first common material for stair treads is ceramic tile. In other words, the tiles laid directly on the stairs can be laid on the stairs of reinforced concrete or steel structure, which are all common paving techniques. The second common stair tread material is stone. General artificial marble is the main stepping stone. Stone steps are also paved, and the commonly used parts are our reinforced concrete stairs and steel stairs. The third common stair tread is made of wood. It is also mainly paved with wooden floors. Generally speaking, wooden stairs can also be used on stairs with reinforced concrete structure or steel structure, and can also be used on stairs with wood structure. When decorating villas and duplex stairs, how to choose the material of stairs? Firstly, the stress structure should be selected according to the height and span of stairs. If the space is large enough and high enough, I personally suggest that reinforced concrete stairs or steel stairs can also be made. For some small-span spaces, such as simple jumps, this is a wooden staircase. The second point is to choose according to the situation of users in the family. In fact, this is also considered from the perspective of use safety. If there are old people or children in our family, it is very easy to fall and bump, so at this time, I personally suggest that you choose wooden stairs instead of stone. Thirdly, let's talk about the choice of indoor stair step. One-step decoration, in the family, I personally suggest that you'd better choose to spread wooden floors. Because the wooden floor is obviously superior to the stone in anti-skid performance and anti-bumping. Of course it's better than tile, so I personally suggest you go to wood structure.
