What are the prerequisites and considerations for building a steel loft?

First, preconditions

First, you will need to consult the civil engineering materials of the original building to understand what original buildings were considered in the design. If it is particularly necessary to avoid the use of zoning schemes in the structural design, then we must first abandon this scheme.

Your house must have sufficient floor height. In general, the lower edge of the floor of a new duplex loft is flush with the lower edge of the original floor. The lower edge of the floor of a single story loft is not less than 2.6 meters. The internal net height of the floor and roof of the attic shall not be less than 2.4 meters, and the minimum value shall not be less than 2.2 meters.

The short span on both sides of the steel structure attic should not be too large. Channel steel construction, generally can not exceed 4 meters, the size can not exceed 6 meters.

Note 2

Before building a steel structure loft, find some professional loft companies to design the attic steel structure.

2. Determine the material of the attic steel structure (span greater than 3.5 meters). Use national standard steel). Some non-professional loft companies advise owners not to use square steel. Square steel cannot be completely rust-proof from the inside out. Easy to oxidize, relatively thin). Channel steel or I-beams should be used correctly.

The frame structure of the house is hollow brick. Channel steel should be used as wall beams when making attics. If there is only one hole in the wall, a channel should be erected. The hollow brick bears a single force. Easy to cut off.

Fourth, the attic steel structure channel steel. According to the joinery board of 1.22m*2.44m, the dimensions of the Angle steel laying are 610mm*610mm. Otherwise, a lot of boards will be wasted.

The channel steel and the Angle steel are welded on the same plane. When the plate is placed under the channel steel for welding, the plate is not reliable and must be smoothed out after welding.

The joint between the channel steel and the channel steel adopts the socket welding method.

Rust prevention is also important. The rigid structure of the package easily absorbs moisture, but it is difficult to disperse moisture (especially the attic on the top of the bathroom). Remove rust before production.
