Abstract

Iron tailing foam concrete and a prefabricated steel-frame wall plate and a construction method thereof are provided, wherein the prefabricated steel-frame wall plate comprises a steel mesh frame, a plurality of wire meshes and a tier of iron tailing foam concrete cast outside the steel mesh frame and the wire meshes; the steel mesh frame is of rectangular mesh structure and comprises an upper guide beam, a lower guide beam, vertical supports and transverse supports; the upper guide beam is arranged horizontally at the top end of the steel mesh frame, and the lower guide beam is arranged horizontally at the bottom end of the steel mesh frame; the vertical supports in a group are connected between the upper guide beam and the lower guide beam transversely and parallelly at intervals; each vertical support is provided with a group of holes along its along axis at equal intervals; the wire meshes are connected within rectangular cells of the steel mesh frame respectively. The technical problem that accumulation of existing iron tailings affects the environment is solved, the prefabricated steel-frame wall plate with good thermal insulation property is produced with the iron tailing foam concrete, and a novel wall is provided for buildings.

Description

technical field [0001] The invention relates to the technical field of an exterior wall of a prefabricated building, in particular to an iron tailings foam concrete, a prefabricated steel frame wall panel and a construction method thereof. Background technique [0002] Although foam concrete is called concrete, it is different from ordinary concrete. It is a foam formed by high-speed stirring or air pressure spraying of foaming agent, cementitious material, admixture, lightweight aggregate and water. After being uniformly stirred in the mixing container, it is poured into products of various specifications or a porous lightweight concrete that is sprayed and poured on site. It is a new type of environmentally friendly and energy-saving material with light weight, good mechanical properties and thermal performance Superior, good shock and shock resistance, sound insulation and noise reduction and other characteristics. [0003] In addition, the huge amount of industrial wast...
