To ensure the safety of the attic, the attic at the top of the slope is absolutely not allowed to cast-in-place the floor, which will become a fixed structure and belong to a typical illegal building.
If the developer has built the floor, there is no need to worry about this problem, but if it is to be added, it is best to use steel structure, taking into account the bearing and stress on the basis of not changing the original structure.
Otherwise, it is equivalent to installing a ""on the head that I don't know when it will detonate.
For the attic with a large area, I suggest that the main beam (main structure) adopts I-beam, and the auxiliary structure adopts 4×4 cm angle steel and channel steel, and the density of angle steel is at least 400×400mm, and then the building formwork (plywood is also acceptable) is paved, and then the laminated wood floor is paved on it.
However, there is always noise when walking on the wooden floor.
To reduce noise, it is best to lay floor tiles, add a layer of steel plate to the steel structure, lay cement sand after hanging steel wire mesh, and then lay floor tiles.
This kind of floor has good sound insulation effect and is much stronger.
The most important problem in the attic at the top of the slope is ventilation. Because there are no doors, small windows and poor air convection, it is necessary to install not only air conditioners but also ventilation equipment, such as an exhaust fan, which can further improve the ventilation situation. For complex, it is necessary to install air supply equipment, such as fresh air system.
2, heat insulation and waterproof
Except for the attic on the top floor of the house, the attic is more comfortable. Its architectural structure is completely different from the general room space, and its design is very interesting.
This attic is rich in spatial structure, but short and cramped. Therefore, in design, we should make full use of the height and shape of the attic according to the preset functions of the owner, which can publicize the characteristics and advantages of the original spatial structure, but we must form a matching of the overall bedroom style.
Hydropower is the first consideration in attic design.
Pay attention to reserve air conditioning lines, otherwise modification will be very troublesome.
In addition, lighting design is also very important.
If the floor is high, you can use a chandelier, which can not only illuminate but also be a good decoration; If the floor is short, or you want a romantic and quiet atmosphere, you can use floor lamps and wall lamps with a strong sense of design.
If you want to design a bar, bathroom or bathroom in the attic, you should consider water supply and drainage in advance. Generally speaking, the attic of villa projects will be reserved for water supply and drainage, as long as they are carefully connected.
But most attics don't have these, so they need to be designed and decorated in advance.
Waterproof design is essential.
The roof and skylight of the attic should be carefully waterproof. The waterproof of the bathroom should be done at the top, and the waterproof of the ground should be done twice 30 cm away from the wall. In addition, after waterproofing is completed, a 48-hour "closed water" test should be carried out. Smallpox passed without wet marks. Otherwise, the waterproof layer needs to be redone, and the place that leaks most easily is the floor drain.
It should be noted that if the location of water supply is changed, the location of water emission must also be changed at the same time, and the construction must be carried out by professionals in strict accordance with the design drawings.
In addition, the most important factor in attic decoration is the insulation of the attic.
Because the attic is located on the top floor, it will be very hot in direct sunlight. In this regard, 20 cm insulation ceiling can be added or covered with insulation materials to prevent the attic from becoming a "steamer".
Step 3 tilt the attic
It is not suitable for use as a bedroom. As long as it is such an inclined attic, no matter what ventilation system is used, I gently and firmly advise the owner not to be a bedroom.
Of course, it is ok to have guests at home occasionally, because the unventilated space does great harm to people who are sleeping.
The best use of this attic is study, reception room, lounge, leisure room or multifunctional space, not even bathroom and kitchen.
What the owner needs to know is that the utilization rate of this attic is not as high as expected. Because of ventilation and lighting, it must be designed as a hollow living room. For example, the area of 100 square meters, the living room is generally nearly 30 square meters, with stairs, floors, corridors and inclined planes. Using 60% is a good design.
The surface of this attic is best decorated with light-colored logs, which can enlarge the space and is the most environmentally friendly. You can highlight a kind of "casual" rather than "formal" like a living room, and you can "sit on the floor" everywhere without too much furniture or ornaments. Creating a comfortable atmosphere is the biggest highlight of the leisure room.
In the process of layout, the main activity space is arranged as high as possible, and the writing desk is placed in front of the window, on which a unique bonsai or flowers are placed.
If it is an audio-visual room, it emphasizes the sound insulation and sound absorption effect more than ordinary audio-visual rooms, and at the same time, it is necessary to make the internal space environment suitable for the best sound effect.
