EMBEDDING MATERIAL FOR CONCRETE SLAB

Japanese Patent JP3810870

B2

PROBLEM TO BE SOLVED: To attenuate vibration of a slab by inertia force of a wt. and to improve vibration resistance by storing the wt. in a wt. storing space part by remaining ranges for movement in the relatively up and down direction and supporting the wt. by an elastic supporting part.
SOLUTION: A case 4 mounted in a mounting hole of a mounting frame material is approximately rectangular parallelepiped made of a foamed plastic and can be divided in the left and right horizontal direction along the central line in the longer direction. A transverse cylindrical wt. storing space part 10 is formed in the case under joined condition and the bottom part of this circular arc-like curved shape is an elastic supporting part 11 (formed polystyrene). Auxiliary wt. storing space parts 12 are formed at the front and the back of the wt. storing space part 10. A wt. 5 to be stored in the wt. storing space part 10 is made by using concrete and the wt. storing space part 10 ensures ranges for movement in the relatively up and down direction to the wt. 5. When a hollow slab constructed by mounting the case 4 in the mounting hole of the mounting frame material receives vibration in the up and down direction and the slab is forced to move in the up and down direction, the movement is restricted by inertia force of the wt. 5.
