Interlocking System for Building Walls, Floors, and Roofs
A wall comprising superposed rows of aligned conventional building blocks being approximately parallel front and back faces connected by a plurality of transverse webs defining chambers there between in which the tops and bottoms of the blocks are formed with V-shaped grooves to mate with similarly shaped V-shaped grooves in the adjacent wall or a block placed thereon. Tubing is placed within the adjacent V-shaped grooves to space the blocks from each other and maintain the adjacent rows in proper alignment. Lateral temperature rods may be placed inside the tubes.
This invention relates to a building block assembly and, particularly, to an arrangement which incorporates a system for aligning the blocks in vertical and horizontal relationships.
BACKGROUND OF THE INVENTIONThe conventional concrete block has been recognized as the least expensive construction material and is a very versatile material since it is both, fire-safe, sound-deadening, and absorbing. It also can be made decorative and is readily available all around the world. Furthermore, it is essentially maintenance free and indestructible. In addition, it is obviously termite-safe and almost tenant-safe. The production of building blocks of this type is highly mechanized and economically productive. However, it does depend for its accurate installation on highly skilled labor. Many attempts have been made to mechanize the installation by using cheap, unskilled labor, but it is not generally satisfactory due to the potential of inaccurate positioning of the interfitting blocks and resulting need for parching, which is very costly. An arrangement that has been employed is my U.S. Pat. No. 4,514,949 which has been generally satisfactory, but it has been found that the point contact occurring with the utilization of spherical balls is not as effective as desired, including the need for light parching.
The general problem that exists, of course is that the existing block producing machines cannot make the blocks accurate to more than 0.050 of an inch in height, and because of this, the accepted tolerance is ± 1/16 of an inch, which in extreme instances can be up to ⅛ of an inch. Accordingly, some means must be provided to accommodate this variation in height to insure proper alignment. Accordingly, it is the purpose of this invention to provide a building block assembly which by the utilization or unskilled workers a wall or similar construction can be constructed with accurately positioned rows of building blocks.
SUMMARY OF THE INVENTIONIn accordance with the present invention, there is provided a building block arrangement which is constructed with V-shaped grooves along the longitudinal walls thereof in which are fitted plastic tubes or plastic reinforced tubes that insure proper alignment of horizontally or vertically disposed rows of building blocks. While this may appear to be a relatively simple construction, it is of an order of magnitude that with the provision of such grooves, the tubes are able to insure proper alignment and thus level rows of building blocks, thus providing the temperature reinforcing rods within the tubes.
In addition, the slot/guide arrangement of the present invention facilitates the process of mounting blocks typically used in residential and commercial construction. Furthermore, the present invention provides a clean process, where no cement between blocks is used, thus increasing not only the speed of the installation process but the number of blocks installed per time frame and at the same providing the opportunity of using untrained labor for the installation.
Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and embodiments thereof, from the claims and from the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGSFurther features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying figures showing illustrative embodiments of the invention, in which:

When it is desired to mount a door frame relative to a block having the novel construction of the V-shaped grooves in the upper walls thereof, there is provided a door frame 48 in which is located a steel plate connector 50. This connector is positioned in a slot 52 formed in the wall of the building block to retain the door frame in place relative to the building block as shown in
Protrusions 91 are provided to accept inventive rods 92 that will fit into the V-shaped grooves of blocks 20, while reinforcing bars and concrete are used to fill the space within blocks 20.
It can be seen from the above that a novel construction is provided whereby the building blocks 20 can be maintained in level position relative to the ground slab. Also, they can be uniformly placed in a level, condition throughout the length of the walls, as shown in
It is intended to cover by the appended claims all such modifications which fall within true spirit and scope of the invention.
