Professional knowledge of building steel attic.

Lead: The attic refers to the smaller floor outside the main floor of the house, including the space below the house with sloping top and the upper space separated by the higher single-story building. The former is generally irregular? People? The top level of the font, which is a regular space. Although the attic space is not big, it has many wonderful uses. Can be used for storage, office, residence, study or studio. The attic is a good private space. Steel attic has the characteristics of firmness and durability, so it has become the choice of many decorators.

What are the main points of building a steel attic?

I. Premises

1 First of all, we need to refer to the original building materials to see what type was considered in the original building design. If the mezzanine scheme that is specifically required to be avoided in architectural design has to be abandoned first.

Your house must have enough stories. Generally speaking, the lower edge of the floor of the newly-built attic in a duplex room is flush with the lower edge of the original floor. The lower edge of the single-story attic floor is not less than 2.6 meters. The internal clear height of the attic floor and roof is not less than 2.4m, and the minimum is not less than 2.2m.. This is based on the premise that people are alive. If your attic is uninhabitable, you can decide the height at will.

3. The shortest attic. The span on both sides should not be too large. In the case of using channel steel, it should generally not exceed 4 meters and the maximum should not exceed 6 meters.

Second, pay attention to the main points

1, before making the attic, it is best to find several professional attic companies to design the design scheme of the steel structure of the attic.

2. Determine the materials used for the steel structure of the attic (the span is more than 3.5m). It is best to use national standard steel). Some unprofessional loft companies recommend owners to use square steel, which is not completely rustproof inside and outside, easy to oxidize and relatively thin. Channel steel or I-beam should be used correctly.

3. The houses with frame structure are all hollow bricks. When you build an attic, you should use channel steel as a beam in the wall. If you just dig a hole in the wall, you can put the channel steel on it. Hollow bricks are single-loaded and easy to scratch.

4. Channel steel for attic steel structure. The maximum size of angle steel laying is 6 10mm*6 10mm, which is determined according to blockboard 1.22 m *2.44 m, otherwise a lot of plates will be wasted.

5, channel steel and angle steel welding must be in a plane. Welding under the channel steel will not be true when placing the plate, so it must be leveled after welding.

6, channel steel and channel steel joint had better use mortise welding method.

7. Rust prevention is also very important. It is easy to absorb moisture when a rigid structure is wrapped inside, but it is difficult to dissipate moisture (especially in the attic above the bathroom). It is best to do rust removal before making.

Matters needing attention in professional construction of steel structure attic

1, security issues

There is no doubt that the first consideration in the attic is safety. The traditional method is the cast-in-place floor of the attic main structure, but the cast-in-place floor can't be integrated with the original building, like the one installed at home? Mines? Is it the same at any time? Explosion? . According to the relevant regulations of our country, the cast-in-place floor of the attic is an illegal building.

2. Selection of materials

In order to ensure the safety of the attic, the original structure of the main building cannot be changed much, and the main materials of the pavilion building should be materials with high strength, small volume and light weight. From these factors, steel structure is undoubtedly the most suitable material. For the attic with a large area, it is suggested that the main structure should be H-beam, the auxiliary structure should be at least 50 angle steel and channel steel, and the density of angle steel should be at least 6 10? 6 10mm, then lay the building formwork (plywood is also acceptable), and then lay the wooden floor or floor tile on it.

3. Sound insulation and noise reduction

It may be simple to lay ordinary wooden boards or wooden floors, but people are prone to noise when walking on them, so sound insulation and noise reduction are also important issues to be considered. From the perspective of home improvement, it is best to lay floor tiles to reduce noise. First, add a layer of building formwork inside the steel structure, then lay a layer of sound insulation and shock absorption pad, and finally lay fine sand and small stone concrete floor tiles. This structure is not only good in sound insulation, but also durable.

4. Decoration and design

Owners can choose decorative elements and styles according to their own preferences. Attic style can be consistent with the original main style, or it can be unique and completely different from the original style. Generally speaking, the attic floor with good comfort is generally designed as a platform, and the top surface treatment is mostly decorated with natural wood materials, and the intervals can be decorated with decorative elements such as wood squares, boards, bookcases, wardrobes and glass.

5. Ventilation

The most important problem in the attic at the top of the slope is ventilation. Generally speaking, the attic has no doors, small windows and poor air circulation, so independent air conditioners can be installed, and ventilation equipment, such as exhaust fans, can further improve the ventilation situation. This better ensures the fresh air in the attic and gives us a comfortable and healthy environment.
