Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiment:

[0025] Such as Figure 1-3 As shown, the rectangular section light steel-small-diameter wood-carbon fiber composite load-bearing column of the present invention is mainly composed of small-diameter wood 1 , angle steel 2 , carbon fiber cloth 3 , light steel pipe 4 , and concrete 5 . It is characterized in that: there is a core steel tube concrete inside, and the periphery is filled with small-diameter timber 1 and reinforced by erecting angle steel 2, and finally wrapped with carbon fiber cloth 3. Due to the layer-by-layer wrapping, it has a good core restraint effect on the internal structure, greatly The bearing capacity of the structure is improved, and the carbon fiber cloth 3 used can significantly improve the overall durability of the structure. At the same time, the cost is low, and the construction is simple and convenient. Due to the reasonable development and utili...

Abstract

The invention discloses a light steel-undersized log-carbon fiber combined load-bearing pillar with rectangular section and a preparation method thereof, and belongs to the technical field of structural engineering. The light steel-undersized log-carbon fiber combined load-bearing pillar with rectangular section is suitable for low-story building and multi-story building structural novel systems; full displacing of mechanical properties of the structures is realized via advantage combination of light steel-undersized log-carbon fiber; durability and bearing capacity of the pillar structure can be increased 30%; engineering cost is reduced 15% because of preferable utilization and exploitation on undersized log; and true green environmental protection low carbon effects are achieved.

Description

technical field [0001] The invention relates to a rectangular cross-section light steel-small-diameter wood-carbon fiber composite load-bearing column and a method thereof, belonging to the technical field of structural engineering. Background technique [0002] With the rapid development of housing construction in my country, in order to meet the growing housing needs of the people and promote the modernization of the housing industry, the State Council "1999" No. 72 document clearly stated: to develop steel structure housing and expand the market share of steel structure housing. The light steel structure is an important part of the steel structure, and its importance is self-evident. Specifically, it can include angle steel, steel pipe, channel steel, and light portal frame. Due to the light weight, high rigidity and easy industrialization of the light steel structure Production, has been widely used in various construction fields. [0003] With the continuous shortage o...
