MORTON M. ROSE/VFELD ATTORNEY United States Patent 3,233,380 WALL STRUCTURE AND BLOCK THEREFOR Morton M. Rosenfeld, Mount Vernon, N.Y. (271 Madison Ave., New York, N.Y.) Filed Mar. 9, 1962, Ser. No. 178,673 1 Claim. (Cl. 52481) This invention relates to a wall structure, and more particularly, to a wall structure which is internally reinforced and a building block capable of being utilized in the construction thereof.

At the present time, there is a need for a internally reinforced wall structure for use in the construction of bomb shelters, fall-out shelters, air raid shelters, foundations of buildings, etc. The wall structure of the present invention is constructed of novel building blocks adapted to cooperate with an internal reinforcement in a manner so that a straight and properly orientated wall may be readily constructed by an unskilled person in a rapid manner. In accordance with the present invention, the internal reinforcement is properly orientated and located in a particular disposition prior to the constructing of the wall. As soon as the internal reinforcement has been properly orientated, the construction of the wall proceeds in a rapid manner with all blocks being orientated with respect to each other and the reinforcement so that a straight wall may be constructed by a novice.

It is an object of the present invention to provide a novel wall structure.

It is another object of the present invention to provide an internally reinforced wall structure.

It is another object of the present invention to provide building blocks capable of being utilized for constructing a wall about anchored orientated reinforcement members, with such wall being provided with a double row of blocks in each course.

It is another object of the present invention to provide a novel building block.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings forms which are presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 1 is a partial perspective view of a wall constructed in accordance with the present invention.

FIGURE 2 is a plan view of the first course of the wall illustrated in FIGURE 1.

FIGURE 3 is a perspective view of the building block utilized in constructing the wall shown in FIGURE 1.

FIGURE 4 is a plan view of the first course of a wall in accordance with another embodiment of the present invention.

FIGURE 5 is a perspective view of the building block utilized in the wall illustrated in FIGURE 4.

Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIG- URE 1 a wall designated generally as 10.

The wall will be constructed of a plurality of courses. For purposes of illustration, the wall 10 includes a first course 14 and a second course 16. Each of the courses 14 and 16 include a first row 18 and a second row 20. Each of the rows and courses of the wall 10 will be constructed from identical building blocks such as building block 22.

As shown more clearly in FIGURES 2 and 3, the block 22 is E-shaped in transverse cross section. The end legs 26 and 28 on the block 22 are identical in length and width. The center leg 24 of the block 22 has a length which is substantially twice the length of the end legs 26 and 28.

The provision of the legs 24, 26 and 28 on the block 3,233,380 Patented Feb. 8, 1966 22 results in recesses 30 and 32 which are identical in size. When constructing the rows 18 and 20 of the first course 14, it will be noted that the blocks 22 in row 18 are longitudinally spaced with respect to the block 22 in row 20 by a distance corresponding to one-half the length of the blocks 22. Hence, the center leg 24 in row 20 will be opposite a leg 26 and a leg 28 on two adjacent blocks in row 18.

In constructing the wall 10, a row of reinforcement members 34 are anchored in an upright disposition to the support 12 in a staggered pattern as illustrated more clearly in FIGURE 2. The staggered pattern of reinforcement members 34 results in two rows, one row of members 34 being adapted to cooperate with row 18 and one row of members 34 being adapted to cooperate with row 20. In constructing the first course 14, it will be noted that the recesses 32 in row 18 are juxtaposed to the recesses 30 in row 20.

When the reinforcement members 34 have been properly orientated, the first course 14 is constructed by inserting the blocks 22 in a direction which is substantially perpendicular to the longitudinal axis of the members 34. Thereafter, the blocks 22 of row 18 in FIGURE 2 are reciprocated to the right until the reinforcement member 34 is in abutting contact with the juxtaposed leg of the block 22. When the blocks of row 20 are placed in position, they are reciprocated to the left in FIGURE 2 until the reinforcement members are juxtaposed to the adjacent leg of the blocks 22. Since the reinforcement members 34 are properly orientated before constructing the wall 10, the blocks in rows 18 and 20 will automatically be orientated with respect to each other as illustrated in FIGURE 2. The blocks in the rows 18 and 20 will be pushed inwardly toward each other until the-reinforcement members 34 in the recesses 30 and 32 engage the outer peripheral surface thereof with a reinforcement member being located in a corner of the recesses as illustrated in FIGURE 2. Hence, it will be noted that the thickness of the wall 14} is automatically maintained constant.. Accordingly, the wall 10 can be constructed by a novice in a rapid manner.

When the first course 14 has been placed in position, the recesses 30 and 32 may be filled with morter or the like which will result in an upright column of cement internally of the wall It). Mortar is preferably placed across the top surface of the blocks in the first course 14. Thereafter, the second course 16 will be provided in a manner so that the blocks in course 16 overlap onehalf of two blocks in the course therebelow. As is conventional in the art, mortar will be provided between the adjacent end faces of blocks in the same row and same course. Likewise, mortar may be provided between the juxtaposed faces of the blocks in the same course but in the rows 18 and 20. As pointed out above, the center leg 24 will always be juxtaposed to a leg 26 and a leg 28 of adjacent blocks in the same row of the samev course.

In FIGURES 4 and 5, there is disclosed another embodiment of the present invention. In FIGURE 4, there is disclosed a plan view of the first course of a wall 10'. The illustration in FIGURE 4 corresponds with the illustration in FIGURE 2 of wall 10.

As shown more clearly in FIGURE 5, the wall 10 is constructed of blocks 40 which are substantially identical with blocks 22 except as will be made clear hereinafter. The center leg 24 of block 40 is provided with a flange 42 extending toward the leg 28'. Hence, the recess 30' will be L-shaped and have a leg 48. The leg 26 of the block 40 is provided with a flange 44 extending toward the center leg 24'. The recess 32 will also be L-shaped and have a leg 50.

The wall It) will also have rows 18' and 20' in each course. The wall 10' is constructed in the identical manneras described above. The wall 10' will be internally reinforced by means of reinforcement members 46 which are C-shaped in transverse cross section. One arm of each reinforcement member 46 is adapted to extend into the leg 48 of recess 30 and the other arm of the .reinforcement member 46 is adapted to extend into the leg 50 of recess 32. As a result of this relationship, it will be noted that the wall 10' is internally reinforced in a vertical and horizontal direction. Since the reinforcement members 46 will be properly orientated before the wall 10' is constructed, the blocks 40 will be properly orientated with respect .to each other and the thickness of the wall 10' will automatically be predetermined as described above. Hence, the wall 10' can likewise be constructed in a rapid manner by a novice. In each of the walls 10 and 10', the reinforcement is completely internal on the wall and the blocks are superimposed over one another in overlapping relationship with mortar being provided between adjacent faces of adjacent blocks.

The building blocks described above may be made from any one of a wide variety of materials including cement, concrete, cinders, etc. The mortar between adjacent blocks may be cementitious in nature or may be an epoxy type resin. The reinforcement members may be made from any one of a wide variety of materials. Preferably, the reinforcement members are made from metal for greatest strength. Before providing the second and successive courses in constructing the walls 10 and 10', the recesses are preferably filled with mortar to provide an additional reinforcement column corresponding to the height of the walls.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claim, rather than to the foregoing specification as indicating the scope of the invention.

I claim:
