Claims
- 1. A concrete masonry block and stud wall comprising:
- a stud frame construction including a plurality of laterally spaced studs which extend vertically between a floor and a ceiling;
- a plurality of concrete masonry blocks having a substantially rectangular shape disposed between pairs of adjacent spaced studs with said blocks being stacked vertically between floor and ceiling, at least one of said substantially rectangular blocks having at one end thereof a recess providing a portion or reduced thickness g in the block near said end adjacent a portion of normal thickness f of said block, wherein g<f, the reduction in thickness (g-F) of said block being sufficient to accommodate an electric junction box so that said box is disposed substantially entirely within said recess to allow wallboard to be applied to the studs, said at least one rectangular block further including a groove means formed in the recess in the portion of reduced thickness and which groove means extends adjacent the normal thickness portion to establish a score line to initiate fracture of a part of said reduced thickness portion upon application of external force thereto leaving a remaining part of said reduced thickness portion in tact with the normal thickness portion of the block, thereby enabling a pair of electrical junction boxes to be mounted adjacent each other to a stud in a common elevation with one of said junction boxes occupying a space directly above said remaining part.
- 2. The wall of claim 1, wherein a maximum thickness of each of said concrete masonry blocks is less than the width of the studs by a sufficient amount so that when one side of the concrete masonry blocks is installed substantially in line with one edge of the studs there is sufficient room for installation of electrical cable and the like between the other side of said stacked concrete masonry blocks and wallboard installed on said stud on said other side of said blocks.
- 3. The wall of claim 2, further including a plurality of strips secured to the inside of adjacent studs and abutting opposite ends of said blocks on at least one side of said blocks to secure said blocks in said stud wall framing.
- 4. The wall of claim 3, wherein said plurality of strips is secured to said studs on two opposite side of said vertically stacked blocks and at both ends of said vertically stacked blocks.
- 5. The wall of claim 4, further comprising said wallboard secured to opposite sides of said studs enclosing said concrete masonry blocks stacked between adjacent studs.
- 6. The wall of claim 1, wherein said groove means includes a pair of grooves formed generally parallel to each other in opposing faces of the reduced thickness portion.
- 7. The wall of claim 6, wherein said grooves extend from one edge of the block a predetermined distance j which is less than the height i of said block.
- 8. The wall of claim 7, wherein the ratio of j to i is approximately two-thirds.
- 9. The wall of claim 8, wherein the height of said at least one block is in the approximate range of 71/2 to 73/4 inches and the length j of said grooves is approximately 5 inches.
- 10. The wall of claim 7, wherein said grooves are tapered and have maximum depths at said edge.
- 11. The wall of claim 10, wherein the amount of concrete material between the grooves proximate said edge has a thickness of approximately 3/4 inch.
- 12. A concrete masonry block for installation in a stud wall frame construction including a plurality of laterally spaced studs which extend vertically between a floor and a ceiling, said block comprising:
- a concrete masonry block made of cementitious material and having a substantially rectangular parallelepiped shape, said block having at each end thereof a portion of reduced thickness providing a recess in the block near each end thereof, said block including two surfaces extending at an angle between a main thicker portion of said block and said block end portions of reduced thickness which provide said recess in each end of said block; and
- groove means formed in the recess in the portion of reduced thickness and which groove means extend adjacent the thicker portions of said block adjacent the angle surfaces to thereby define a score line to initiate fracture of a part of said reduced thickness portion upon application of external force thereto leaving a remaining part of said reduced thickness portion in tact with the thicker portions, thereby enabling a pair of electrical junction boxes to be mounted elevationally adjacent each other to a stud.
- 13. The block of claim 12, wherein said groove means includes a pair of grooves formed generally parallel to each other in opposing faces of the reduced thickness portions.
- 14. The block of claim 13, wherein said grooves extend from one end of the block a predetermined distance j which is less than the height i of said block.
- 15. The block of claim 14, wherein one of said grooves formed in each reduced thickness portion includes a groove side wall formed in the angle surface of the block.
- 16. A concrete masonry block and stud wall comprising:
- a stud wall frame construction including a plurality of laterally spaced studs which extend vertically between a floor and a ceiling:
- a plurality of concrete masonry blocks each having a substantially rectangular parallelepiped shape disposed between pairs of adjacent spaced studs, with said blocks being stacked vertically between floor and ceiling;
- each of said substantially rectangular blocks having at each end thereof a portion of reduced thickness providing a recess in the block near each end thereof;
- a maximum thickness of each of said concrete masonry blocks being less than a width of the studs by a sufficient amount so that when one side of the concrete masonry blocks is installed substantially in line with one edge of the studs there is sufficient space for installation of electrical cable and the like between the other side of said stacked concrete masonry blocks and wallboard installed on said studs on said other side of said blocks;
- the reduction in thickness at the end of each of the concrete masonry blocks and the recess thereby provided being sufficient to accommodate an electric junction box when wallboard is applied to the studs on said other side of said blocks;
- and further including a layer of resilient caulking material and the like disposed as a substantially continuous bead between adjacent generally horizontal rows of said stacked concrete blocks for absorption of high frequency sound energy.
- 17. The concrete masonry block and stud wall according to claim 16, wherein said blocks have at one end thereof of said reduced thickness a groove means which groove means extends adjacent the thicker portions of the block to establish a score line between the thicker portions and reduced thickness portions to initiate fracture of a part of said reduced thickness portion upon application of external force thereto leaving a remaining part of said reduced thickness portion in tact, thereby enabling a pair of electrical junction boxes to be mounted elevationally adjacent each other to a stud within the wall.
