FLOOR DEVICE FOR BUILDING

Japanese Patent JP3900035

B2

PROBLEM TO BE SOLVED: To solve a problem of a conventional floor device, wherein the floor device may lack strength depending on the length of header joists based on the size of the same; and to provide a floor device for a building, which ensures a sound insulation effect, simplifies its structure and operation, and reinforces the strength of the header joists.
SOLUTION: In construction of the floor device, a plurality of header joists 5 are arranged in a manner being borne by the building 1, and bearing means 31 each having an air pressure-based elastic body 34 are arranged between the header joists 5 and a floor slab 2, followed by arranging floor boards 42 over the header joists 5. Thus vibrations applied to the floor boards are absorbed by the header joists, and therefore a sound insulation effect of the floor device can be expected. Further the header joists are borne by the bearing means 31, and therefore the strength of the header joists is reinforced, whereby a reinforcing structure is achieved by simplifying linking operation etc. irrespective of the length based on the size of the header joists. Furthermore bearing by the bearing means is carried out by the air pressure-based elastic body, and therefore load bearing is smoothly achieved by elastic deformation of the elastic body.
