(Cl. 72-46) This invention relates to concrete blocks and to structures composed of the same, such as walls or other parts of buildings or similar structures. One of the objects of the invention is to provide a reinforced concrete block assembly for use in the erection of buildings, and which will be of extraordinary strength; which will be fire-resistant; which will require a minimum amount of lumber in the building and which can be very easily erected by masons or other workers having little skill or experience in building construction.

Another object of the invention is to provide a plurality of cooperating concrete blocks which are cemented, reinforced and interlocked together in a manner to result in a building wall or other part of exceptional strength and rigidity. Still another object of the invention is to provide a novel means for tying together and reinforcing the associated blocks, with means provided in the blocks for receiving and concealing the reinforcements; for providing air spaces and ventilation between slabs forming part of the block assembly and for producing a strong and rigid wall or other building structure.

With these and other objects to be hereinafter set forth, in view, I have devised the particular arrangement of parts to be described and more particularly pointed out in the claim appended hereto.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed, Fig. 1 is a perspective View of a concrete block constructed in accordance with the invention; Fig. 2 is a sectional view, taken on the line 22 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a perspective View of another type of block, or that herein referred to as the slab type; Fig. 4 is a sectional view taken on the line 4- of Fig. 3, looking in the direction of the arrows; Fig. 5 is a top plan view of a corner block; Fig. 6 is a face view of another form of slab type of block; Fig. 7 is a View looking at the right edge of the slab type of Fig. 6; Fig. 8 is a perspective view showing an assembly of several of the blocks according to the invention, and Fig. 9 is a face View of a wall constructed according to the invention.

In carrying out the present invention, a number of types of concrete blocks are employed, examples of several of the types used being shown at I to 4 inclusive in the drawings. The type of block shown at I is an intermediate block and is of a width defining or determining the thickness of the Wall structure of which it forms a part. The block I has the two

parallel side walls

5 and 6 which, in the erection of a wall or other building structure, form the opposite faces thereof. The end walls of the block are indicated at I and 8 and each of these walls has its outer face formed with the spaced vertically-extending grooves 9 which receive the concrete or mortar in the erection of the wall. Located between these grooves 9 is a vertically-extending rib I0 and the walls I and 8 are provided with an aperture or vent I3 which extends through the ribs I0 as clearly seen in Fig. l.

The upper and lower edges of the walls I and 8 are grooved as shown at II, these grooves II being aligned with the grooves 9.

I The block shown at 2 is of the slab type, and is of a thickness considerably less than one-half of the width of the block I and the wall of which the block I forms a part. The slab 2 may be made in various lengths and one of its ends, or that shown at I4, is provided with a tongue I5 for interlock with a recess of complementary shape provided on an adjacent slab when two of the slabs are placed end-to-end in a wall or building structure.

Such a recess is shown at IS in the end II of the slab 2.

It will be noted that the slab 2 is provided in its edge with the groove I8 which extends completely around the edge of the slab and also extends through the tongue I5 as will be clearly apparent from Fig. 3. Extending centrally and longitudinally through the slab 2 is a continuous passage I9 which emerges at one end at the center of the tongue I5 and its other end in the center of the recess Hi. This passage is intended for the reception of a tie wire 32 in a manner to be presently explained.

The block 3 shown in Figs. 6 and 7 is another of the slab types employed in the improved construction. In the form shown the same is provided with the tongue I5 and with the groove I8 in its edge similar to that shown in the slab 2. Slab 3 is also provided with the passage I9 for the reception of a tie wire 32. This form of slab is provided with a straight edge and instead of having a tongue I5 provided on its opposite edge 2 I, it might be provided with av recess,

.such as that shown at I6 in Fig. 3.

The block shown at 4, in Fig. 5 is of the corner type, that is to say, it is of full width of the walls and is provided with the two smooth or

unbroken walls

22 and 23 at right angles to one another. The two remaining walls shown at 24 and 25 are the inner walls and are provided with the ribs I0 and the top and bottom grooves II opposite through which the vents I3 are provided. The

outer walls

22 and 23 might also be initially formed with vents as shown at 26, which vents might later be sealed after the wall is erected.

In Figs. 8 and 9 is shown one manner in which a wall or other similar building structure can be erected by the use of the blocks heretofore described. A corner structure or post member is built up by superimposing a number of the corner blocks 4 upon one another. The corner post thus erected is reinforced by a plurality of vertical reinforcing rods 30 which extend continuously down through the hollow centers of the corner blocks 4, the centers of these blocks being filled around the reinforcin wires with mortar, as shown at 3| in Fig. 8. These vertical reinforcing rods can be tied together by wires extended around them. The wall structure leading from the corner blocks may be largely composed of the

slabs

2 and 3 with blocks such as shown at I interposed in the wall at intervals to strengthen the resultant structure. In the form shown, each of the

slabs

2 and 3 is twice as high as the blocks I and 4 and when the slabs are placed endwisely against one of the blocks l or 4, the tie wires 32 extending through the passages I9 in the

slabs

2 and 3 and projecting therefrom will extend through the grooves II in the blocks I or 4 to reach the vertically-extending reinforcing rods 30 extending down through the centers of these blocks. These wires may be curled or wrapped about the rods 30 as shown at 33 in Fig. 8. It will be noted that when two slabs are placed against one of the blocks I or 4, the ribs I will lie between the slabs and maintain the same in properly spaced relation and thus provide an air space in the wall. It will be further seen that the vents I3 extending through the walls of the blocks I and 4 communicate with the space between the slabs so that ventilation may be thus established through the wall. Passages through the mortar fill 3| can be maintained by the use of pipe inserts through the apertures I3 and across the interior of the block which inserts can be withdrawn when the mortar has hardened.

By the use of properly positioned

slabs

2 and 3 in the wall, with regularly inserted blocks I, a strong and sturdy structure is provided. The interlock at the ends of the slabs effected by the tongue and groove arrangement described, not only aids in the positioning of the slabs, but greatly strengthens the structure. A wall may be easily and accurately laid with the blocks because the spacing ribs I0 aid materially in aligning the slabs, and the reinforcing means extending through the blocks and slabs effectively ties the structure together. In laying up a wall such as shown in Fig. 9, the customary procedure of placing the end or corner blocks 4 in place is carried out, followed by the placement of the slabs 3 between them. As each row of slabs is placed in position, the reinforcing rod 32 is inserted through the slabs with the ends extended for bending around the vertical tie wires 30 in the corner blocks as indicated at 33. It may be found desirable to use short, overlapping lengths of reinforcing rod, as is known in concrete reinforcement, as a substitute for continuous lengths, should certain methods of laying up the blocks differing from those outlined, be required to be followed.

While I have herein described the blocks and slabs as being of certain shapes and proportions, it will be apparent that these shapes and proportions may be varied according to various requirements of a building and to meet assemblies around doors, windows and other structures. By the employment of blocks constructed as herein described and assembled in an almost endless number of ways, buildings employing a minimum of wood and steel are possible and the structures so made being fireproof and of exceptional strength.

What I claim is:

In a concrete block wall construction, a pair of spaced-apart wall slabs providing an air space between them, a hollow block adjacent to one end of the slabs, said block having opposite walls, at least one of which is arranged with a central vertical rib positioned between the slabs and maintaining the slabs in spaced relation, each slab having a continuous circumferential groove in its edge, at least some of the slabs being provided with a tongue at one end and a notch at the other end, the groove extending through said tongue and notch, said slab having a central horizontal tie rod passage through it, each passage being surrounded by parts of the body of a respective slab, said tie rod passage emerging at one end in the notch and emerging at the other end out of the tongue in those slabs which are provided with a tongue and notch, the slabs being each of greater height than the block, the block having spaced grooves provided in the upper edge of its ribbed wall, said spaced grooves being in axial alignment with the tie rod passages in the slabs, tie rods extending through the tie rod passages and entering the interior of the block through said grooves, and air passages through the ribbed portions of the walls of the block for establishing communication between the interior of the block and the air space between the slabs.
