Description

A wooden wall panel with oblique steel strips for cold-formed thin-walled steel composite walls

technical field

The invention belongs to the technical field of construction, and relates to a wooden wall panel used for forming a wall panel of a cold-formed thin-walled steel composite wall.

Background technique

The structural form of the cold-formed thin-walled steel structure residence is derived from the light wood structure residence. In order to improve the situation that the traditional wood structure uses a lot of wood but fails to give full play to the performance of wood, conform to the trend of protecting the environment and saving resources, and make up for the shortcomings of traditional light wood structure buildings such as low number of floors and small building area, etc., A type of steel-wood composite wall with cold-formed thin-walled steel as the wall skeleton and wood boards as wall panels is widely used in cold-formed thin-walled steel structure housing systems. In steel-wood composite wall panels, the wall panels made of wood panels are not only the main thermal insulation, heat insulation, and sound insulation components, but also the main shear components that resist horizontal forces such as wind loads and horizontal earthquakes. Therefore, it is of great significance to optimize and improve the wooden wall panels constituting the steel-wood composite wall.

At present, the construction technology of steel-wood composite walls imported from North America is mostly used in China. This technology requires that two boards of the same height as the floor be fixed on both sides of the steel wall skeleton at the construction site, and the edges of the boards are connected with the steel wall by screws. Flange connection. The main problems with this common wall plank are:

1. The large volume of cladding boards is not conducive to transportation and installation on the construction site, which increases transportation costs, construction costs and construction time;

2. The installation of cladding boards requires a large number of screws, the construction process is cumbersome, and the construction period is long, which reduces the construction speed and efficiency;

3. The hollow wall composed of cladding boards and section steel has poor thermal insulation, sound insulation and fire prevention performance;

4. The structural contribution of cladding wood panels is small, and the utilization rate of wood performance is low;

5. The connection between the cladding board and the steel column is screw connection, and most of the energy is dissipated in the shear failure of the screw, which makes the structural system prone to instability.

6. Most of the common cladding panels now use oriented strand board imported from abroad, which is not the mainstream wood structure panel in China, and the cost is relatively high.

In recent years, domestic scholars have conducted some research on the wood wall panels that make up steel-wood composite walls, and proposed some new types of wood wall panels. However, the existing novel wooden wall panels still have the disadvantages of poor seismic performance and insufficient shear bearing capacity.
