1 Claim. (Cl. 72-41) This invention relates to masonry and building construction and more particularly to novel building blocks adapted to be arranged in courses in the construction of walls for buildings and the like.
The primary object of the present invention resides in the provision of a building block which can be used in the erection of walls and the like and which will avoid the use of comparatively small or narrow mortar bedding areas of building units, thereby eliminating shell bedding which has numerous disadvantages, one of the most important of which is the resultant improper bonding of adjacent and superimposed blocks.
A further object of the present invention is to provide building blocks which minimize the tendencies of cavities to split the building block and the wall built'of these blocks into vertical sections either parallel or crosswise under stress of an applied load.
The present invention employs diagonal grooves which intersect to form V-shaped grooves, thereby providing diagonal crossing insulation and assuring maximum strength for a wall built of these units.
An additional object of the invention is to provide building units for use in erecting masonry walls and the provision of suitable V-shaped grooves opening into the upper and lower surfaces thereof to provide an insulative air barrier which is continuous throughout the length of the block and of a wall constructed of these blocks and which provides a barrier to heat transfer in any direction transversely of the building blocks.
Still further objects and features of this invention reside in the provision of building blocks which are strong and durable, and which are simple and inexpensive to produce by molding or any other suitable method.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by these precast masonry units, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:
Figure l is a perspective view of a portion of a wall constructed in accordance with the concepts of the present invention;
Figure 2 is a plan view of one form of building block contemplated by this invention;
Figure 3 is a vertical sectional view as taken along the plane of line 3-3 in Figure 2;
Figure 4 is an end elevational view of the building block shown in Figure 2;
Figure 5 is an enlarged perspective view of the building block illustrating the manner of arrangement of the V-shaped grooves in detail;
Figure 6 is a perspective view of a modified form of the invention employing two pairs of V-shaped grooves;
Figure 7 is a view of a further modification of the invention also employing two pairs of opposed V-shaped grooves; and
Figure 8 is a plan view of a yet further modified form of the invention.
2,847,848 Patented Aug. 19, 1 958 "ice With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a wall constructed of building blocks formed in accordance with the concepts. of the present invention. The section of the wall 10, is arranged in courses, such as 11, 12 and. 14 of building blocks 16, the individual building blocks being vertically superimposed and staggered in relationship with a superposed building block overlying portions of two of the building blocks of the course therebelow.
Each of the blocks 16 include substantially V- shape grooves 18 and 20 with the groove 18 opening into the top 22 of the block 16, and the groove 20 opening into the bottom 24 of the block. The groove 18 has its apex 26 extending towards the side 28 of the building block 16 while the groove 26 has its apex 30 adjacent the side 32 thereof.
The grooves 18 and 20 extend substantially half-way through the building block 16 and intersect, as at 34 and 36, thereby affording a continuous air space in the building blocks and a continuous air barrier against penetration transversely of the building block 16. Further, because of the relatively narrow dimensions of the grooves 18 and 20, considerable areas of the building blocks may have mortar applied thereon to thereby afford a better bond for the blocks.
In the erection of the various courses 11, 12 and 14 of the building blocks, the grooves 20 of a block about to be superimposed on an already positioned course of building blocks will be so arranged that the grooves 20 thereof align with the grooves 18 in the lower blocks of the lower course of building blocks. This will assure that the air barrier will be continuous.
Referring now to the embodiment of the invention as is shown in Figure 6, it will be noted that herein there is disclosed a precast masonry unit which can be formed of any suitable material and is generally designated by reference numeral 40. The building block 40 includes a top 42 and a bottom 44 and a pair of V-shaped grooves 46 and 48 are provided in the body of the block 40 which opens into the top 42 thereof. Likewise, two pairs of grooves, as are indicated at 50 and arranged in opposite relationship with respect to the pairs of grooves 46 and 48 are formed in the body of the block 40 and open into the bottom 44 thereof. The apices of the grooves 46, 48 are opposed to the apices of the grooves 50.
Referring now to the embodiment as is shown in Figure 7, it will be noted that herein there is shown a modified form of the invention which includes a building block including a top 62 and a bottom 64. Two pairs of grooves 66 and 68 as well as 70, 72 are formed in the top 62 and bottom 64, respectively, and it is noted that while the apices of the grooves 66 and 68 are arranged so that they are the closest portion of the grooves 66 and 68 to each other, the apices of the grooves 70 and 72 are widely spaced. .This arranges the apices of the grooves 66 and 70 in opposite relationship as well as the apices of the grooves 68 and 72 which are oppositely disposed. The depth of the grooves 66, 68, 70 and 72 is such that the grooves will intersect to provide a continuous air passage as well as a continuous air barrier in the building blocks.
In the modified form of the invention shown in Figure 8, the building block includes a top 82 having a groove 84 therein of the shape as shown. A groove 86 is formed in the bottom of the block 80. The grooves are so arranged whereby they do not extend half-way through the block allowing portions thereof to be superposed above each other.
The foregoing is considered as illnstrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and changes may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
A building block comprising a body having a top and a bottom, said body further having sides and end walls, said body having a first substantially V-shaped groove opening into said top and saidend walls thereof, said body having a second substantially V-sl1aped groove opening into said bottom and said end walls thereof, said first groove and said second groove being oppositely disposed, the apices of said grooves being disposed towards opposite sides of said block, each of said grooves 4 extending substantially halfway through said body, said UNITED STATES PATENTS 314,022 Heard Mar. 17, 1885 738,643 Van Camp Sept. 8, 1903 877,874 Tsanoff Jan. 28, 1908 2,154,754 Kemp Apr. 18, 1939 2,165,101 Hudson July 4, 1939 FOREIGN PATENTS 20,462 Great Britain of 1908 255,562 Great Britain of 1926
