Problems solved by technology

However, in the above combination forms, the wood needs to be spliced ​​and planed, and the connection with the steel is also required to be tightly bonded (connected with adhesives, bolts, lag screws or wood screws, etc.), and the steel and wood are along the entire length of the component. It is a whole, which increases the weight of the components, and also increases the cost of materials and components, and the use of glue is not conducive to environmental protection

Embodiment Construction

[0020] As shown in each figure, in this embodiment, a steel-wood composite column includes a steel column and a wooden column 2. The steel column includes an upper steel column 11 and a lower steel column 12 to save materials. The upper steel column 11 and the lower steel column 12 are respectively cold-formed thin-walled steel pipes, the height of the upper steel column 11 is 0.8m, the height of the lower steel column 12 is 1m, and the upper steel column 11 and the lower steel column The cross-section of the steel column 12 is quadrangular, and the wooden column 2 has four pieces, which are evenly distributed around the upper steel column 11 and the lower steel column 12. The wooden column 2 is a log, and there is no need to treat the surface. It not only saves production costs, but also is environmentally friendly and beautiful, avoiding landscape engineering that requires materials, and the cold texture and touch of all-steel materials.

[0021] The upper steel column 11 is...

Abstract

The invention discloses a steel-wood combination column. The steel-wood combination column comprises steel columns and wood columns, the steel columns comprise an upper steel column and a lower steel column, the number of the wood columns is at least two, the upper steel column is connected with the upper ends of all the wood columns through an upper connecting mechanism, and the lower steel column is connected with the lower ends of all the wood columns through a lower connecting mechanism. The section arrangement is flexible, the steel columns serve as main stress components, the wooden columns provide lateral rigidity for the components, column top loads and wind loads are transmitted to the lower steel columns through reliable connection, the overall rigidity is improved, the superiority of steel and wood can be fully exerted, the stress performance of the structural components is optimized, a new reference and a new choice are provided for design and application of a steel-wood composite structure, a new thought is provided for development of a fabricated steel-wood structure, and popularization and application of the steel-wood structure can be better promoted.

Description

technical field [0001] The invention relates to a steel-wood composite column. Background technique [0002] In the prior art, the steel-wood structure is a new type of combined structure. Both steel and wood are green and environmentally friendly materials. Steel and wood are combined (joined) in different ways to give full play to the performance advantages of the two materials and make up for their shortcomings. Better for engineering practice. [0003] From the existing research on steel-wood composite columns, the bearing capacity of steel-wood composite columns can be greatly improved. Steel-wood composite columns generally have two combination modes, one is steel-clad wood composite columns, that is, the wooden column is the main compression member, and thin-walled steel is arranged around the wooden column, and the thin-walled steel is made into a steel hoop to restrain the wood. There is also a combination of wooden columns and C-shaped cold-formed thin-walled ste...
