Abstract: The present invention provided a precast modular concrete wall panel having a rectangular wall body with an upper slot and two side slots, and the wall body can further include an insulating layer and a decorative layer, and can contain a sandwich layer embedded in the concrete structure. The wall panels may be used with wall columns, wall corners and other components to form a wall panel system and further to form a building of frame structure or frame-share wall structure. Such wall panels have advantageous structural features and thus can be cost effectively prefabricated, and the construction process using such panel system can be performed with high efficiency.

Abstract: A spatial light steel frame concrete building and a method for constructing the same are provided. The building comprises: a wall spatial light steel frame; a floor slab spatial light steel frame connected to the wall spatial light steel frame to form a building unit spatial light steel frame; and concrete poured in the building unit spatial light steel frame. The wall spatial light steel frame and the floor slab spatial light steel frame each comprise a welded mesh reinforcement, and a plurality of trellis profile steels spaced apart from each other and each having a plurality of stretching holes. Each trellis profile steel comprises two wing edges parallel to each other and a plurality of web members between the wing edges which are integrally formed, the stretching holes are defined by the web members, and the web members and the stretching holes are formed by stretching the wing edges.
