Floor and column structure

A floor and column structure, consisting of floors and columns, wherein each of the floors is composed of a floor iron sheet (1), square pipes (2), a floor steel grating (3), a lower impermeable membrane (4), rigid plastic foam (5), an upper impermeable membrane (6) and cement stone concrete (7);

• each of the columns is composed of a column iron sheet (11), column steel gratings (12), steel posts (13) and cement stone concrete;
• the floor iron sheet (1) is fixedly welded to the column iron sheet (11);
• the floor iron sheet (1) can completely seal the bottom of each floor;
• the column iron sheet (11) can completely wrap each column;
• an upper surface of the floor iron sheet (1) is welded to a lower part of each of the square pipes (2);
• the square pipes (2) perform a function of reinforcing the iron sheet (1), and the square pipes (2) are each provided with a thin pipe wall so that slotting and installation of electric wires beside the square pipes (2) are convenient;
• an upper part of each square pipe (2) is welded to the floor steel grating (3);
• the floor steel grating (3) is welded to the steel grating (12) and the steel posts (13) at an upper part of, each column, and the floor iron sheet (1), the square pipes (2) and the steel grating (3) and the column iron sheets (11), the steel gratings (12) and the steel posts (13) are welded into a framework, which is firm and not prone to collapse;
• the columns and the bottom of the floors are cast with cement stone slurry for reinforcement;
• the lower impermeable membrane (4), the rigid plastic foam (5) and the upper impermeable membrane (6) are provided over the floor steel grating (3);
• the lower impermeable membrane (4), the rigid plastic foam (5) and the upper impermeable membrane (6) are sandwiched between the floor steel grating (3) and the cement stone concrete (7) for vibration isolation and acoustic and thermal insulation, which can prevent conduction of vibration, sound and heat between adjacent floors;
• the lower impermeable membrane (4) and the upper impermeable membrane (6) have an anti-seepage function and can prevent sewage in pipelines in the plastic foam layer from leaking vertically;
• a drain pipe (9) from a hand washing basin, a dish washing basin, a bathroom, etc. and a sewage pipe (8) from a toilet are connected in parallel in the plastic foam layer and then joined to a main pipe, which is arranged in a pipeline groove beside the column;
• a gas pipe, a heating pipe, an air conditioner pipe, a water pipe and various cables extend separately from the main pipe in the pipeline groove beside the column, pass through the plastic foam layer and enter a user meter box;
• the pipes and cables are arranged in the plastic foam layer, and not concreted with the cement stone slurry, which is convenient for installation and maintenance;
• the upper impermeable membrane (6) can prevent the overlying cement slurry from flowing into the plastic foam layer;
• the cement stone concrete (7) is provided over the upper impermeable membrane (6);
• the cement stone concrete (7) is hard and can bear large loads;
• and the surface of cement stone concrete (7) is treated separately.
