Abstract

A masonry block is disclosed having a pair of spaced opposed side walls forming only a single cavity therebetween. The side walls define the outer side periphery portions of the block and include mutually facing inner surfaces. At least two opposed web walls extend between the side walls. The web walls have inner surfaces extending between the inner surfaces of the side walls. The web walls include channels situated intermediate the ends of the inner web surfaces. The channels extend in a top-to-bottom direction and converge toward the bottom of the block. An insulative plate of thermally insulative material is disposed in the cavity with the ends thereof being mounted in the channels. The insulative plate is situated intermediate the side walls to divide the cavity into a pair of air cells separating the insulative plate from the side walls. The single cavity formed between the side walls may be partitioned into a plurality of cavity portions by one or more intermediate web walls.

Dependent claims

A masonry block comprising:

a pair of spaced opposed side walls forming only a single cavity therebetween, said cavity being open at its top and bottom ends;
said side walls defining the outer side periphery portions of said block, and having mutually facing inner surfaces;
at least two opposed web walls extending between said side walls;
said web walls being integral with said side walls and having inner surfaces extending between the inner surfaces of said side walls;
said web walls including channel-forming means situated intermediate the ends of said inner web surfaces for forming channels extending in a top-to-bottom, said channels being mutually convergent in a downward direction;
insulative plate means of thermally insulative, compressible material disposed in said cavity with the ends thereof being mounted in said channels;
said plate means having an uncompressed, end-to-end dimension which is longer than the distance between the lower ends of said convergent channels, so that with said plate means being disposed in said channels the ends of said plate means are compressed to snugly frictionally engage said channels;
said insulative plate means being situated intermediate said side walls to divide said cavity into a pair of air cells separating said insulative plate means from said side walls, said air cells each being open at their open at their top and bottom ends.

A masonry building block comprising:

a pair of side walls forming only a single cavity therebetween, said cavity being open at its top and bottom ends;
said side walls having mutually facing inner surfaces;
a pair of outer web walls extending between the ends of said side walls;
said outer web walls having inner surfaces;
at least one intermediate web wall situated intermediate said outer web walls, said intermediate web wall extending between said side wall inner surfaces in a direction parallel to said outer web walls and dividing said cavity into a plurality of cavity portions;
said outer web walls and said intermediate web walls being integral with said side walls and extending substantially the full height of said side walls;
said intermediate web wall having opposed surfaces;
each of said outer web wall surfaces and said intermediate web wall surfaces having a channel oriented in a top-to-bottom direction, with mutually facing ones of said channels converging in a downward direction;
and
insulative plate means comprising a plurality of plate portions of thermally insulative, compressive material disposed in each cavity portion, with the ends of each plate portion being mounted in mutually facing pairs of said channels;
said plate portions each having an uncompressed, end-to-end dimension which is longer than the distance between the lower ends of said convergent channels in each cavity portion, so that with said plate portions being disposed in said channels the ends of said plate portions are compressed to snugly frictionally engage said channels;
said insulative plate portions extending parallel to said side walls intermediate said side walls to form a pair of air cells in each cavity portion;
each air cell being defined by a portion of the inner surface of one of said side walls, portions of the inner surfaces of a pair of said web walls, and one side of one of said insulative plate portions, with each air cell being opened at its top and bottom ends.
