REENFORCEMENT O13 PLASTEE BLOCKS.
Application filed. August 21, 1923. Serial No. 653,513.
other angular relation such, for example, as
is required in wall corners.
Other objects and certain advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings in which,
Figure 1 is a top plan view of a portion of a straight wall construction employing the units embodying my invention.
Figure 2 is a top plan view of a portion of angularly disposed adjoining walls employing units embodying my invention.
Figure 3 is an end view of one of the units shown in Figures 1 and 2.
Figure 4 is a side elevation of a tie.
In the drawings wherein for the purpose of illustration, is shown what I at present consider the preferred form of my invention, the numeral. 5 indicates a. portion of a straight wall construction made up of a plurality of blocks or units 6 adj oined in an end to end relation. These units are formed of plaster Paris composition or other suitable material and are provided upon opposite edges with longitudinal grooves 7. lVhen the blocks are superimposed one upon the other, as shown in Figure 3, the grooves 7 register with each other and by reason of such registration form mortar receiving passages 8 adapted for the retention of mortar or other cementing material 9. or cementing material, as will be readily appreciated, is applied to the grooved faces of the units 6 as the building of the wall progresses, and thus by reason of the presence of the mortar or cementing material within the passages 8, the units are efi'ectively keyed or locked together.
In order that a suitable mortar or cementing material may be introduced between This mortar the adjacent ends of the blocks afterthe same have been placed in position within a plain or straight wall construction, I have so grooved the ends of the units that the registering grooves will form pockets or cement cavities into which the cementing material may be introduced from the face of the wall. These grooves are indicated by the numeral 10 and form with each other pockets or cement cavities 11 into which the cementing material 12 may be introduced from the side of the wall through a throat or restriction 13 formed intermediate the beveled faces 14 of the adjoining units. Ad jacent each groove 10 of each block or unit, there is formed a projection or wing 15 the faces 16 of which meet-in an angular relation when the units are employed in a straight wall construction such as is illustrated in Figure 1. If desired, tie-rods 17 may be incorporated into the cementing material 12 as an additional. reenforcement for the wall construction in its entirety. These tie-rods as will be readily appreciated, are placed in position within the pockets 11 be: fore the cement 12 is introduced, and upon hardening of the cement they become, in effect, an integral part thereof. It will be noted that the grooves 10 are so formed as to mould the cement 12 into a key 12 pro,- vided with indentures 18 into which fit the wings 15 thereby interlocking the units 6 with the moulded cement key in such a way that it would be impossible to move one of the blocks longitudinally with respect to the other in separating the same without breaking the'wings 15, adjacent the faces 16, from their respective units.
Referring now to Figure 2, wherein is shown adjoining angularly disposed walls employing units embodying my invention, it will be noted that the wings 15 are mamtained in a spaced relation, whereas the opposite corners of the sections join each other, as shown at 19. The faces 14 of the units are so inclined or beveled with respect to the units themselves that they lie in diverging planes when the units are joined, as shown in Figure 2, thus affording spaces 20 which communicate with the pockets or cement cavities 21 formed by reason of the presence of the grooves 10. Aspreviously mentioned, the wings 15 in the case of angularly disposed adjoining walls, are separated and thus permit access to be gained to the pockets 21 through the throats 22 formed therebetween.
The cementing material 12in the case of such a wall as is shown in Figure 1, is introduced through the throat 13 formed intermediate the beveled faces 14, but in the case of angularly disposed adjoining walls, the cementing material 12 is introduced through the throats 22 thereby filling the spaces 20 and the pockets 21. Upon introducing material into the pockets 21, keys 22 are form-ed'having fins 23 which fit into the spaces QOafiord'ed between the beveled faces 14. The keys thus formed are provided .with ribs 23 having indentures into which fit the corners 25 of the units 6. It will be appreciated from this construction that the units are prevented from moving in the direction of the arrows at by reason of the engagement of the" corners with the ribs 23; and it will also be appreciated that the units are prevented from moving longitudinally in the direction of arrows F) by reason of the fact that the wings 15 are fitted into the indentures and engage the ribs 23.
If desired, tie-rods 17 may also be einployed in connection with the wall shown in Figure 2, which tie-rods are, as previously mentioned, placed in position before the cementing material is introduced and are thereafter held by reason of the hardenmg of the material around the same, In the case of a shaftway construction employin'g, as shown, four side walls and four corners, a tie-wire 27 may be arranged within the grooves 8 intermediate the several sections. This tie-wire is preferably passed around the tie-rods 17, as shown in Figure 2, and function, as is obvious, to reenforce the structure in its entirety, thus lending rigidity to the same and insuring safety. In the case, however, of a straight wall construction, the tie-wire may be omitted and ties 28 substituted therefor. These ties are relatively short and are provided with hooks 29 which are driven or otherwise imbedded into the blocks upon opposite sides of the joints formed therebetween, thus lending rigidity and strength to the structure as a whole.
While I have shown and described What I at present consider the preferred form of my invention, it is to be understood that various changes in the same as to certain details of construction may be resorted to without departing from the spirit of theinvention or the scope of the subjoined claim;
I claim:
In a wall structure, a pair of wall units arranged in an adjacent relation, each of said units being provided at its end with a groove, the grooves of said units forming with each other a cement cavity between said units, each of said units being provided with a face adjacent said cavity, said faces being spaced from each other and forming with each other a throat leading from said cavity to the exterior of said wall structure, .a wing carried by each of said units adjacent its groove and projecting into said cavity, a key arranged within said cavity and provided with a solid portion in said throat and formed with ribs arranged witlrin said grooves and provided with indent'ures adjacent said ribs, said wings projecting into said indentures and cooperating with said ribs to prevent separation of one unit from the other.
In testimony whereof, I have aiiixed my signature to this specification.
