Concrete filled steel tube inner support

Abstract

The invention discloses a concrete filled steel tube inner support. The concrete filled steel tube inner support comprises a supporting plate, a supporting pipe is fixedly connected to the middle endof the top of the supporting plate, and the inner side of the supporting pipe is coated with JS waterproof paint. Meanwhile, the inner side of the JS waterproof paint is coated with an epoxy coal pitch coating, the outer side of the supporting pipe and the outer side of the supporting plate are both coated with iron oxide red phenolic aldehyde antirust coatings, and the outer sides of the iron oxide red phenolic aldehyde antirust coatings are coated with carbon fiber reinforced polymers CFRP. The supporting pipe is arranged, and people can pour concrete into the supporting pipe, so that the overall supporting strength of the supporting piece is effectively improved; the carbon fiber reinforced polymers CFRP are arranged, the overall strength of the supporting pipe and the supporting platecan be improved, and the overall rust resistance of the supporting pipe and the supporting plate can be improved through the iron red phenolic aldehyde antirust coatings; the epoxy coal tar pitch coating is arranged, and the corrosion resistance of the inner side of the supporting pipe can be improved; and the JS waterproof coating is arranged, the waterproofness of the inner side of the supporting pipe is improved, and therefore the service life of the whole supporting piece is prolonged.

[0002] Architecture refers to material products piled up with heavy material materials. It is a "second nature" created by human beings to meet the needs of their own living, communication and other activities. It is also the most basic space environment for human daily life. Architectural art is through It is a comprehensive practical plastic art formed by the aesthetic treatment of architectural group organization, building shape, plane layout, three-dimensional form, structural modeling, combination of internal and external spaces, decoration and decoration, color, texture, etc. Architecture is an important part of human beings. One of the forms of material culture, steel components are needed in the construction process of the underground diaphragm wall, but the existing steel components have low strength and poor corrosion resistance, which reduces their service life. Therefore, we propose Concrete steel tube inner support
