Abstract
In one aspect the invention provides an interlocking masonry block including a rear face, a front face, at least one aperture extending vertically through said block for receiving a flowable concrete mixture used in core filling, and at least one generally vertical side being registerable with an opposing side of an abutting block to inhibit movement of said flowable concrete out through a vertical interface between said blocks.
Claims18
An interlocking masonry block for constructing a wall together with other masonry blocks comprising:
- a front wall and a rear wall connected by at least one web member;
- at least one aperture extending vertically through said interlocking masonry block for receiving a flowable concrete mixture used in core filling said wall;
- the front wall including first and second vertical sides adjoining a front face and the rear wall including first and second vertical sides adjoining a rear face, the first vertical sides of the front and rear walls having first engagement members and the second vertical sides of the front and rear walls having second engagement members, said first and second engagement members registerable with a correspondingly shaped engagement member extending down an opposing side of an abutting block or blocks to inhibit movement of said flowable concrete out through a vertical interface between said interlocking masonry block and said abutting block or blocks;
- wherein each of said first engagement members comprise vertical first, second, and third planar portions, said first and third planar portions at an acute angle to said corresponding front or rear face, said first planar portion adjoined to a vertical edge of the second planar portion and said third planar portion adjoined to an opposite vertical edge of said second planar portion, such that said second planar portion is intermediate said first and third planar portions and is at an obtuse angle to said corresponding front or rear face;
- wherein each of the second engagement members comprise adjoined vertical first, second, and third planar portions, each of said first, second, and third planar portions being parallel to a corresponding first, second, or third planar portion of said first engagement members;
- whereby the first and second engagement members are configured to cooperate with said correspondingly shaped engagement member of said abutting block or blocks;
- and
- the front and rear walls including respective upper bedding faces, each having a plurality of spaced apart lugs extending upwardly therefrom, or adjacent thereto, for engagement with an underside portion of an overlying block or blocks.
5 more elements
A method of dry stacking masonry blocks for use in constructing a mortarless steel reinforced concrete wall including the steps of:
- providing a plurality of interlocking masonry blocks, each of the plurality of interlocking masonry blocks including a rear wall portion, a front wall portion, an upper bedding face having a plurality of spaced apart upwardly extending lugs, a lower bedding face, at least one vertical aperture extending through said masonry block for permitting passage of reinforcement bars and flowable concrete, the front and rear wall portions each having a first vertical side and an opposite second vertical side, each of said first vertical sides including a first engagement member extending along the length of the first vertical sides, each of said second sides including a complimentary second engagement member expending along the length of the second vertical sides, wherein said first and second engagement members each comprise planar first, second, and third vertical portions, wherein said first and third vertical portions are at an acute or obtuse angle to the respective front or rear wall portion, and the second vertical portion is adjoined between said first and third vertical portions, said second vertical portion at either an obtuse or acute angle, opposite of said first and third vertical portions;
- positioning a first course of said plurality of interlocking masonry blocks on a foundation having vertical reinforcement bars extending upwardly therefrom, said first engagement members registering with said second engagement members of adjacent interlocking masonry blocks, the configuration of the first and second engagement members of adjacent interlocking masonry blocks are opposite;
- positioning a second course of said plurality of interlocking masonry blocks on top of the first course wherein said plurality of interlocking masonry blocks of the second course engage with at least some of the plurality of spaced apart upwardly projecting lugs of the plurality of interlocking masonry blocks of the first course and at least some of the vertical apertures of the plurality of masonry blocks interconnect;
- positioning subsequent courses of said plurality of interlocking masonry blocks thereon;
- and
- filling a core of the wall by introducing a flowable concrete mixture into the interconnecting vertical apertures of the plurality of interlocking masonry blocks, wherein the first engagement members bear against the second engagement members of adjacent interlocking masonry blocks to inhibit movement of the flowable concrete out between vertical interfaces between abutting interlocking masonry blocks without requiring mortar to seal said vertical interfaces.
