This application proposes a washed stone structure for steel structure staircase floors, comprising a steel structure staircase and a washed stone composite layer. The steel structure staircase includes risers and treads, both of which are covered with the washed stone composite layer. The washed stone composite layer, from bottom to top, consists of an anti-rust paint layer, a cement-based interface agent layer, a washed stone layer, and a washed stone topcoat layer. This application constructs a synergistic protection system adapted to both the steel structure substrate and the cement-based decorative surface layer through layered design and functional optimization of the washed stone composite layer. By setting the anti-rust paint layer, cement-based interface agent layer, washed stone layer, and washed stone topcoat layer, this application isolates air and moisture from reacting with the steel structure, while also preventing interface separation caused by stress concentration, avoiding hollow areas and delamination, ensuring the flatness and safety of the staircase floor, and achieving the effect of "rust-free, hollow-free, non-detaching, pollution-resistant, and long-lasting" for the steel structure staircase washed stone floor.

The utility model discloses a large-size block double-face high-precision leveling device which comprises a frame body, rails installed on the two opposite sides of the frame body, a roller shaft arranged in the frame body, and a floating rule fixedly arranged at the bottom of the roller shaft, the two ends of the roller shaft are in sliding fit with the rails, and adjusting bolts vertically penetrating through the frame body are arranged at the four corners of the frame body. The adjusting bolt is in threaded fit with the frame body; an infrared emitter is mounted on one side, corresponding to the two ends of the track, of the frame body; rollers are arranged at the two ends of the roller shaft respectively, the rollers are arranged in a track in a rolling mode, a track groove is formed in the track in the length direction of the track, and the rollers are arranged in the track groove in a rolling mode. The height and the thickness of the adhesive are adjusted through the fine adjustment bolts, the reference is corrected through infrared rays, the construction efficiency is high, and the problems of repeated adjustment and low efficiency are solved.

The utility model discloses a kind of magnetic woven belts, it is related to woven belt field, and its technical solution main points are as follows: including woven belt body, it is characterized by: woven belt body is composed of upper layer weaving layer, lower layer weaving layer and intermediate interlayer;Positioning groove is separately provided in intermediate interlayer along the length direction of woven belt, long strip-shaped magnetic block that is adapted to the width of woven belt is embedded in positioning groove, the upper surface and lower surface of magnetic block are closely combined with upper layer weaving layer and lower layer weaving layer respectively;Upper layer weaving layer and lower layer weaving layer edge are sewn by weaving thread, intermediate interlayer and upper layer weaving layer and lower layer weaving layer are filled with hot melt adhesive layer, and form integral structure after solidification.The utility model realizes hoisting without artificial winding bottom by magnetic adsorption, reduces operation difficulty and security risk, simultaneously enhances the connection stability with article, and structure firm no hollowing, long service life, comprehensively solve the use problem of traditional woven belt.
