Environment-friendly energy-saving wallboard of engineering structure

The environment-friendly energy-saving wallboard of the engineering structure comprises a wallboard body, clamping blocks are symmetrically welded to the top end and the bottom end of the wallboard body, clamping grooves are symmetrically formed in the two side ends of the wallboard body, and placing mechanisms are installed at the four corners of one end of the wallboard body. The placement mechanism comprises mounting blocks, sliding holes, fixing rods, sliding plates, rotating shafts, rotating blocks, threaded grooves and rubber blocks, and the mounting blocks are symmetrically and fixedly connected to the four corners of one end of the wallboard. One end of each rubber block is far away from one side of the corresponding wallboard, so that a plurality of wallboards can be conveniently placed and transported, due to supporting of the rubber blocks at the four corners of each wallboard, pressure borne by the wallboards is more uniform, and the situation that the installation protrusion at one end of each wa
