The attic, that is, the building compartment, is a secondary structure. It has the following methods: 1. The steel structure is covered with wooden laminated timber, pine, large core board, and bamboo glue. My understanding of several types of boards is integrated
The wood is not suitable for deformation and the standard size and cost are slightly higher than other boards. Pine boards are prone to deformation when exposed to moisture. Large core boards
Non-environmentally friendly bamboo glue boards are also available, but none on the market are too If it makes a little ding-dong sound when stepped on, it is recommended to use
laminated materials.
The construction of cast-in-situ concrete requires the wall to have sufficient load-bearing capacity because its dead weight is very large. It is generally used in public places and households. Many secondary structures are not load-bearing at all. It is recommended to use steel structures.
It is stronger to use columns for support at locations that are not load-bearing walls.
3. Nowadays, most owners use steel-concrete combination (steel structure is covered with steel plates and concrete is made, which has good sound insulation effect
,
).
Design Description
This structural design is based on light steel structure design and complies with the national light steel structure design specifications.
, The main beam of the steel structure adopts (,,,,,,) I-beam. The main beam and embedded parts are fully welded, and anchor bolts are used to connect and reinforce the wall. After the main body of the steel structure is completed, apply anti-rust paint twice. The main beam is made of floating steel plate, and the upper part is made of rebar and wire rod to form high-strength mesh-type reinforcement. The interior is filled with ceramsite concrete and the concrete floats up to 1 cm.
Based on this structure, the seismic coefficient is calculated as degrees, and the service life is more than years.
, Steel structure design and construction specifications
Steel structure high-strength bolt connection construction specifications
Main load high-strength bolts can bear pressure/root ( )
Active load/㎡.
According to the design specifications of steel structures, the fire resistance limit in this design scheme ranges from ℃ to
℃, and the limit time is about minutes. Exceeding the limit will cause structural damage and affect normal use.
