Subassembly and wall structure are restrainted to steel pipe

The utility model provides a subassembly and wall structure are restrainted to steel pipe relates to the electric cooking field. The steel pipe is restrainted the subassembly and is included casing and connecting piece, the casing is a plurality of, is vertical connection between a plurality of casings, is vertical connection between a plurality of casings, and the connection can be dismantled through the connecting piece respectively in the both ends of a plurality of casings. When having alleviated the steel pipe and having restrainted the length overlength of subassembly, the problem that has a sticky concrete skewness of carrying in the cavity to it restraints the problem that the size of subassembly can not change according to the actual demand of actual building construction work toreach the steel pipe. The utility model provides a steel pipe is restrainted the subassembly and is included a plurality of casings, and is vertical connection between a plurality of casings, has avoided the steel pipe to res
