Straw concrete light steel keel self-insulation wallboard and construction method thereof

Abstract

The invention provides a straw concrete light steel keel self-insulation wallboard and a construction method thereof. The wallboard comprises a ceiling keel, two groups of opposite C-shaped cold-formed thin-walled steel keels, OSB boards, a ground keel and straw concrete, and the OSB boards comprise an upper OSB board and a lower OSB board. The two groups of opposite C-shaped cold-formed thin-walled steel keels are arranged in parallel, the two ends of the C-shaped cold-formed thin-walled steel keels are fixedly connected with the ceiling keel and the ground keel respectively to form a keel frame, the two OSBs are fixed to the upper end face and the lower end face of the keel frame, and each group of opposite C-shaped cold-formed thin-walled steel keels comprises two C-shaped cold-formed thin-walled steel keels and a plurality of lacing bars; and the two C-shaped cold-formed thin-walled steel keels are arranged up and down, openings of the C-shaped cold-formed thin-walled steel keels are right opposite, the lacing bars are fixed to the two C-shaped cold-formed thin-walled steel keels, and the space defined by the two OSBs is filled with the straw concrete. According to the straw concrete light steel keel self-insulation wallboard and the construction method thereof, a cold bridge effect of cold-formed thin-walled steel in the wallboard is blocked through the straw concrete and a novel keel structure, and the heat preservation and heat insulation performance of the wallboard is improved. Meanwhile, the straw concrete prevents the cold-formed thin-walled steel from buckling damage.

Description

technical field [0001] The invention belongs to the field of thermal insulation wall panels, and in particular relates to a straw concrete light steel keel self-insulation wall panel and a construction method thereof, which is an external thermal insulation wall panel of light steel structure houses in villages and towns used in severe cold or cold regions. Background technique [0002] At present, the cold-formed thin-walled steel light steel keel wall panels used at home and abroad mostly adopt the "sandwich system" of two plates and one core; the cold-formed thin-walled steel keel mostly adopts the structure of the wall panel, which leads to the cold bridge phenomenon of the wall panel Obviously, it is not conducive to popularization and use in severe cold and cold regions; and this kind of wallboard uses glass fiber, rock wool and other materials to directly fill the wallboard, so that the wallboard has a "hollow feeling" and the phenomenon of insufficient hanging force o...

[0002] At present, the cold-formed thin-walled steel light steel keel wall panels used at home and abroad mostly adopt the "sandwich system" of two plates and one core; the cold-formed thin-walled steel keel mostly adopts the structure of the wall panel, which leads to the cold bridge phenomenon of the wall panel Obviously, it is not conducive to popularization and use in severe cold and cold regions; and this kind of wallboard uses glass fiber, rock wool and other materials to directly fill the wallboard, so that the "hollow feeling" of the wallboard and the phenomenon of insufficient hanging force of the wallboard

In addition, materials such as rock wool and polystyrene foam particles are all products of modern chemical smelting, which consume a lot of resources after numerous processes
