Abstract

Abstract This invention relates to a sound insulating building block that insulates, absorbs or irregularly reflects incident sound waves. The block contains a cover therein. The cover contains a sound absorbing plate formed into a plate shape of mineral fibers such as glass wool or asbestos or other ordinary fibers additionally attached to the mineral fibers. The sound absorbing plate is inserted into the cover in tight contact with the inside of the cover and the cover is then received into an open block made of mineral matter such as concrete and having side plates on the circumference. The cover is provided on its facing panel with slits or holes designed to face the open portion of the block.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 124 words
A sound-insulating building block comprising: a. a thick walled structural support member of sound-insulating material having a main wall and two side walls defining a compartment with three open sides; b. a thin walled panel member having a main side and upper and lower sides and inserted in and cooperating with said support member to enclose said compartment, said main side having a plurality of apertures therein to permit the passage of incident sound waves into said compartment; and c. a partition member of sound-absorbing material spanning the upper and lower sides of said panel member within said compartment and defining respective air spaces between its opposite surfaces and the main side of said panel member and the main wall of said support member.
Claim 2
Dependent Claim 124 words
A sound-insulating building block comprising: a. a thick walled structural support member of sound-insulating material having a main wall and two side walls defining a compartment with three open sides; b. a thin walled panel member having a main side and upper and lower sides and inserted in and cooperating with said support member to enclose said compartment, said main side having a plurality of apertures therein to permit the passage of incident sound waves into said compartment; and c. a partition member of sound-absorbing material spanning the upper and lower sides of said panel member within said compartment and defining respective air spaces between its opposite surfaces and the main side of said panel member and the main wall of said support member.
Claim 3
Dependent Claim 41 words
A block as in claim 1 wherein said main side of said panel member has a zigzag surface with said plurality of apertures formed in the outermost edges thereof to permit the passage of all incident sound waves into said compartment.
Claim 4
Dependent Claim 29 words
A block as in claim 1 further comprising means on the outer ends of said side walls of said support member for holding said panel member in cooperation therewith.
Claim 5
Dependent Claim 31 words
A block as in claim 1 further comprising means on the inside of said upper and lower sides of said panel member for holding said partition member upright in said compartment.
Claim 6
Dependent Claim 26 words
A block as in claim 1 wherein said main side of said panel member is inclined with respect to said main wall of said support member.
Claim 7
Dependent Claim 39 words
A block as in claim 1 wherein said two side walls of said support member and said upper and lower sides of said panel member are formed with cooperating filler grooves for receiving steel setting bars and filling mortar.
Claim 8
Dependent Claim 41 words
A block as in claim 1 wherein the inner surfaces of said two side walls of said support member taper outwardly from said main wall and the upper and lower sides of said panel member taper inwardly from said main side.
Claim 9
Dependent Claim 21 words
A block as in claim 1 wherein said support member is of concrete and said partition member is a mineral fiber.
Claim 10
Dependent Claim 176 words
A composite structure composed of a plurality of stacked sound-insulating building blocks, each of said blocks comprising: a. a hollow box-shaped structural member of sound-insulating material having a main wall and two side walls and openings in the upper, lower and one lateral surface thereof; b. a cover member having a top plate, a bottom plate and a facing plate respectively fitted in said openings in the upper, lower and one lateral surface of said structural member and cooperating therewith to enclose the interior thereof, said facing plate having apertured means for permitting the passage of all incident sound waves into said interior; c. a sound-absorbing panel member fitted between said top and bottom plates within said interior and defining respective air spaces between its opposite surfaces and said facing plate and said main wall of said structural member; and d. said two side walls of said structural member and said top and bottom plates of said cover member being formed with cooperating filler grooves for receiving filling mortar to connect adjacent ones of said blocks.
Claim 11
Dependent Claim 176 words
A composite structure composed of a plurality of stacked sound-insulating building blocks, each of said blocks comprising: a. a hollow box-shaped structural member of sound-insulating material having a main wall and two side walls and openings in the upper, lower and one lateral surface thereof; b. a cover member having a top plate, a bottom plate and a facing plate respectively fitted in said openings in the upper, lower and one lateral surface of said structural member and cooperating therewith to enclose the interior thereof, said facing plate having apertured means for permitting the passage of all incident sound waves into said interior; c. a sound-absorbing panel member fitted between said top and bottom plates within said interior and defining respective air spaces between its opposite surfaces and said facing plate and said main wall of said structural member; and d. said two side walls of said structural member and said top and bottom plates of said cover member being formed with cooperating filler grooves for receiving filling mortar to connect adjacent ones of said blocks.
Claim 12
Dependent Claim 122 words
A sound-insulating building block comprising: a. a thick-walled support member of sound-insulating material having a main wall and two side walls; b. a thin-walled box-shaped compartment member fitted in said support member and having a top plate, a bottom plate and two facing plates with one of said facing plates disposed against said main wall and the other of said facing plates having a plurality of apertures therein and the open ends of said compartment member disposed against said side walls defining a hollow compartment enclosed by said support member and said compartment member; and c. a panel of sound absorbing material disposed in said compartment and spaced from said main wall and said apertured facing plate defining respective air spaces therebetween.
Claim 13
Dependent Claim 122 words
A sound-insulating building block comprising: a. a thick-walled support member of sound-insulating material having a main wall and two side walls; b. a thin-walled box-shaped compartment member fitted in said support member and having a top plate, a bottom plate and two facing plates with one of said facing plates disposed against said main wall and the other of said facing plates having a plurality of apertures therein and the open ends of said compartment member disposed against said side walls defining a hollow compartment enclosed by said support member and said compartment member; and c. a panel of sound absorbing material disposed in said compartment and spaced from said main wall and said apertured facing plate defining respective air spaces therebetween.
