Abstract

The invention discloses a compressed-steel sandwich combination wallboard comprising a lateral frame, compressed steel, a concrete or cement mortar face layer and core material, wherein the concrete or cement mortar face layer comprises an upper face layer and a lower face layer which are respectively connected with the lateral frame. The core material is arranged between the upper face layer and the lower face layer. The compressed steel is arranged in the combination wallboard and connected with the lateral frame or the concrete or cement mortar face layer. The compressed-steel sandwich combination wallboard integrates the characteristics of thin-wall compressed steel plate, such as good ductility and high strength, and the characteristics of lightweight core material, such as greenness and environmental protection. Due to the reasonable design of the cross section, the compressed-steel sandwich combination wallboard not only solves the problems of durability of steel products and the fire resistance of core materials and also fully uses the characteristics of each component. The compressed-steel sandwich combination wallboard not only can be used as the structure of the normal filling wallboard body, but also can be used as the shearing wall with high anti-seismic requirements, so that the compressed-steel sandwich combination wallboard is specially used as the shearing walls of high-rise buildings, filling walls of frame structures, outer walls of industrial workshops, and structures of other retaining wall.

Description

technical field [0001] The invention relates to a steel sandwich composite wallboard, more specifically, a profiled steel sandwich composite wallboard used in the field of civil engineering structures, which can be used for housing construction, industrial workshops, etc. Wall or infill wall structures. Background technique [0002] Over the years, my country's wall building materials have always been brick masonry with clay as the main raw material, and have long been in the era of traditional building materials called "Qin bricks and Han tiles". Until the early 1990s, the proportion of clay solid brick wall materials used in my country was as high as 95%, while that of the former Soviet Union was 38%, that of the United States was 15%, and that of Japan was only 3%. According to statistics, in my country, the area of ​​arable land destroyed due to the production of clay bricks is about 6,700 hm per year. 2 , resulting in the loss and waste of a large amount of farmland, ...
