UNITED STATES ARTHUR- H. GOOMBS, OF ATASCADERO, CALIFORNIA, ASSIGNOR OF ONE-FOURTH T PATENT OFFICE.
WENDELL COOMBS HILL, OF WASHINGTON, DISTRICT OF COLUMBIA.
Application filed September 19, 1922. Serial No. 589,209.
To all whom it may concern:
Be it known that I, ARTHUR H. Coomns, a citizen of the United States, and a resident of Atascadero, in the county of San Luis 6 Obispo and State of California, have invented certain new and useful Improvements in Building Constructions, of which the following is a specification.
The present invention relates to concrete 1 building constructions and more particularly to the forms for such constructions and the devices for making such forms.
The object of the invention is to provide a construction that will be universal in its application and which will obviate the necessity for separate wooden or metal forms to be used in the process of construction and then removed. With this object in View, the invention contemplates the provision of slabs or blocks of concrete or other suitable building material of various shapes and sizes having edges designed to cooperate with each other so that the blocks or slabs can be easily and quickly united to make forms for the walls and other parts of concrete or reinforced concrete structures. The forms so constructed and united in place will remain as a conglomerate part of the entire structure and will not be removed after the wall is finished as are wooden or metal forms heretofore used. It will be obvious that the provision of these universal forms that will permanently remain as an integral part of the structure will result in a more economical and efficient method of building.
Another object of the invention ancillary to the main object is the provision of a novel means for affording additional stability to the walls, to hold the slabs or blocks in proper spaced relation and to impart rigidity to the form while being filled with concrete.
These and other objects that might hereinafter appear are attained in the manner made apparent by the foregoing description and the accompanying drawings forming a part thereof and in which:
Fig. 1 is a sectional plan view of a form constructed of the slabs or blocks showing ties and reinforcing rods in position before the concrete is poured between the walls.
Fig. 2 is vertical sectional view of spaced blocks with a tie in position on the blocks and reinforcin rods in position on the tie. Fig. 3 is a fragmentary vertical view of a double wall form with the concrete filled in and the tie in position. Fig. 4 is a plan view of the tie employed in the double wall construction.
Referring to the drawings, the reference character 1 designates the slabs for the out wall of the structure and 2 designates m;
slabs for the inner wall, said slabs having vertical tongue and groove joints 3 and eaclr of the slabs or blocks having a groove l and a tongue 5 both horizontally disposed as shown more clearly by Fig. 2. The pro vision of the vertical tongued and grooved edges makes possible the easy and rapid uniting of the blocks to assemble the form, and the provision of the horizontally disposed tongues and grooves .not only matcrially hastens the assembly of the blocks but affords a very convenient and advantageous means for permitting a most effective disposition of the ties 6 which may be placed at the corners of the forms as shown as well as being distributed along the length of the wall at any suitable points.
The tie 6 may be and preferably is made of steel and is provided with the intermediate corrugated portion 7 for the purposes to be later described, and the ends 8 and 9 formed with the ribbed portions as shown and received within the grooves; 4 of the spaced blocks 1 and 2. Theends and 9 of the ties have the integral depending portions 10 and 11, the distancebetween these portions 10 and 11 being equal to the thickness of the slab. The. ties are forged from a flat piece of steel of "suitable thickness, width and length.
Reinforcing rods 12 are placed at any desired points in the construction and, as
shown more clearly by Fig. 2, these rods are disposed within the corrugations of the ties 6 and are thus prevented from getting out of place. The corrugated portion 7 besides serving to properly position the reinforcing rods 12 also serves to cooperate with the concrete to securely bind the walls together. The ties being accurately made of definite sizes greatly facilitates the proper spacin of the slabs to form the outlining walls or the structure. It will be obvious that, if necessary or desirable, vertical reinforcing rods may be supplied and in this event they may be secured to the art.
In Fig. 3 there is shown a double wall construction embodying the invention. This construction consisting of the walls 13 and 13 and the intermediate walls 14 and 14 providin a space therebetween which may be used or any desired purpose. The walls of this construction are formed from blocks the same as those used in the single wall construction and are provided with the same vertical and horizontal tongues and grooves. In Fig. 4 there is illustrated a tie 15 designed for use with the double walled forms and is similar to the tie 6 used with the single wall construction and may or may not be provided with the intermediate corrugated portion. The tie 15 comprises a fiat piece of steel having the ends 16 and 17 and the intermediate portions 18 and 19 ribbed as shown to be received in the grooves of the slabs in the same way as the tie 6 is received in the grooves 4 of the slabs 1 and 2. The ends 16 and 17 have the depending portions 20 and 21 adapted to fit over the to of each block of the walls 13 and 13*, an the depending portions 22 and 23, the space between the portions 20 and 22 and 21 and 23 being equal to the thickness of the slab. The intermediate portions 18 and 19 are provided with the depending strips 24 and 25 and 26 and 27, respectively, the space between the pairs of strips being equal to the thickness of the slabs. It will be apparent that the ends and intermediate portions may be formed by simple mechanical operations, such as punching, cutting and stamping, and the cost and facility of manufacture are factors reatly in favor of the ties thus described.
t will be easily understood that the slabs may be united by mortar joints and the thickness of the joints will be determined by the thickness of the ties. As concrete buildings are usually faced with stucco, brick, terra cotta or other material, the depending portions of the ties on the outside walls of the structure will be covered by the particular material and hence will not be visible.
The slabs have been shown as unreinforced, but as is obvious, they may be reinforced in any well known way, and if it is desired, small reinforcing rods mav be vertically or horizontally disposed within the slabs to thereby afford the desired reinforcing.
Certain designs in architecture are common to most buildings and in view of this fact the method of building constructions is very practical. It is possible to keep in stock more than ninety per cent of the slabs used to form the outlining walls of the structure of almost any shape and at the same time it is not necessary to carry in stock any material that is not usable universally. In a large class of buildings, the necessary slabs would be of straight lines and angular and it is thus apparent that such slabs could always be kept in stock. In another class of buildings, the slabs might be of strai ht lines, angular and also curved, and it W11 likewise be apparent that a certain number of curved slabs proportionate to the slabs of other shapes could always be kept in stock. In other cases a few special forms might be required but such cases will be very few and will form a very small percentage of the total amount of build- I-Iaving thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:
1. In a wall construction a plurality of horizontally and vertically disposed blocks arranged to form two outlining walls spaced from each other to receive filling material therebetween, said blocks being formed with horizontally disposed grooves and ribs, and ties between blocks of each wall provided with ribs received into the grooves of the blocks and extending transversely of the base of the grooves.
2. In a wall construction a plurality of outlining walls in spaced relation to receive filling material therebetween, said walls being formed from a plurality of blocks pro vided with interfitting tongues and grooves, and tie members between said walls provided with ribs received into certain of said grooves and corrugations between said ribs to augment the binding action between the ties and the filling material.
3. In a wall construction two outlining walls in spaced relation constructed of blocks provided with interfitting tongues and grooves, and tie members provided with portions shaped to fit transversely between the tongue and-groove of two interfitting blocks.
4:. In a wall construction two outlining walls in spaced relation adapted to have filling material therebetween, said walls being constructed of blocks having interfitting tongues and grooves, tie members between said walls havmg endportions provided with ribs received in the grooves of a block in each wall and an intermediate corru ated spaced vertical extensions at each end thereof.
6. A tie rod for wall constructions having spaced vertical extensions at each end thereof adapted to overlap the sides of building blocks and a projection at each end of the rod betweensaid extensions adapted to be received in a groove of the blocks.
7. A tie rod for wall constructions provided with vertical extensions for spacing the blocks of parallel walls and an intermediate corrugated portion for supporting reinforcing rods in spaced relation.
8. A tie rod for Wall constructions provided with vertical extensions for spacing the blocks of parallel walls, an intermediate corrugated portion for supporting reinforcing rods in spaced relation, and end projections adapted to be received in grooves of the blocks.
9. A tie rod for Wall constructions having an intermediate corrugated portion and a rib at each end thereof adapted to be received within a groove of the block.
In Witness whereof, I hereunto aflix my signature.
