BUILDING CONSTRUCTION.

Application filed January 22, 1919.

To all whom it may concern:

Be it known that I, EDWARD NOTTEBOHM, a citizen of Germany, residing at Manila,

in the Philippine Islands, have invented new and usefulImprovements in Building Construction, of which the following is a specification.

This invention relates, to building construction. I

It is the principal object of this invention to provide elements for use in building construction which are preferably made of concrete and which may be readily assembled and optionally arranged to produce building structures of various design, at the same time utilizing a minimum of material and providing an entirely fire-proof structure.

The present invention contemplates the use of sectional blocks which interlock with each other to form columns and which are further provided with receiving grooves into which the edges of interlocking wall slabs may be positioned, all of said members being formed of concrete.

The invention is illustrated by way of example in the accompanying drawings, in which Figure I is a view in perspective illustrating afragmentary portion of a wall disclosing the wall slabs and the columns.

Fig. 2 is a view in side elevation illustratin one of the wall slabs.

igs. 3 and 4 are views in sideand end elevation respectively disclosing the tongues and grooves of the slabs.

Fig. 5 is a View in plan elevation illustrating one of the column blocks.

Fig. 6 is a view in vertical section through the block as seen on the line 66 of Fig. 5.

Figs. 7 and 8 are views in plan and section respectively disclosing another form of column block.

Fig. 9 is a view in perspective illustrating a beam used in the present construction.

Referring more particularly to the drawings, 10 indicates slabs which are particularly shown in Figs. 2, 3 and l as having marginal tongues 11 on two of their edges and correspondin grooves 12 upon the two opposite edges. hese slabs are quite thin and may be combined to form a narrow paitition wall, as shown in Fig. 1. The grooves at the ends are provided with interlocking pins 13 which project into corresponding recesses in the contiguous ends of the adjacent slabs.

Specification of Letters Patent.

"Patented. July 6,1920.

Serial No. 272,580.

The walls are provided with corner columns 14 and intermediate posts 15. i The corner columns have vertically extendinggrooves 16 which may be brought to register throughout the combined lengths-of the column blocks and will receive the ends ofthe wall-forming blocks. When corner columns I are used for a simple wall the grooves only extend down two sides ,of the columns, as shown in Fig. 7. When the columns are made for intermediate bracing of the wall the grooves are formed upon the opposite sides, as shown in Fig. 5. It will be readily understood, however, that the column blocks may be of any design to accommodate one or more partitions and will thus be formed with a proper number of grooves 16.

The columns are composite and are formed with a series of superimposed blocks having upwardly extending lips 17 and recessed cavities 18 into which the lip of the lower block projects. It is'preferred, from an economical standpoint, to form these blocks hollow and they may thus be built up and cemented together along their horizontal joints to combine with the courses of the slabs and form the complete structure. When permanent structures are built it is desirable to superimpose the walls formed of the slabs upon beams, as shown in Fig. 9. These beams extend and rest upon underpinning and are formed with upper grooves 19 into which the lower edges of the slabs may rest. The beams may be reinforced throughout their length as desired. In fact, when building large structures as shown, it may be desirable to reinforce the walls between the columns and this is done by suitably anchoring reinforcing wires'20 to the columns and stretchingfthem along the horizontal joints between the wall slabs. They will thus combine; to hold the columns together and when embedded within the cement applied to the joints of the slabs will firmly reinforce the entire wall construc tion and hold it against cracking. The long beams shown in Fig. 9, with the under pinning and the grooves 19 serve as a support for the shorter sections 10 and the tongues fit into the grooves. These shorter sections are united by the tongues and grooves at the ends. The reinforcin. wires 20 extend,

of a frail nature and the tongue and groove portion of the adjacent blocks is quite narrow, it is comparatively weak when it crosses the vertical joints of the shorter blocks and the metal reinforcements at these points are necessary to preserve the joints against jars, shocks or settling which would destroy or weaken these joints.

It will thus be seen that the building construction here disclosed embodies the use ofsimple duplicate elements which may be cheaply manufactured and readily assembled to form outside walls and intermediate partitions for buildings.

While I have shown the preferred form of my invention as now known to me, I wish it understood that various changesmay be made in the construction, combination and arrangement of parts by those skilled in the art without departing from the spirit of my invention as claimed.

Having thus described my invention,

what I'claim and desire to secure by Letters Patent is: r

A wall of the character described, including a series of hollow, vertical sectional posts having alternate tongues and grooves formed to interlock the meeting ends of the sections, and vertical grooves in said posts in the line of the wall, a series of superimposed concrete slabs with interlocking tongues and grooves upon their horizontal meeting edges, and tongues upon their vertical ends to engage the vertical grooves of the posts, and the contiguous slabs, and bonding members by which said slabs and posts are united.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
