Interlocking blocks for temporary structure
The building block interlocks with other like blocks by means of mating tongues and grooves or mating projections and recesses to form a temporary structure such as a garage or a factory. The block is hollow and less an opening through which particulate material may be selectively introduced and extracted from the hollow interior. The block may be composed of light-weight material such as polypropylene or other polymeric material so that the block can be carried and lifted easily by hand when it is empty.
This invention relates to building blocks for temporary structures and more particularly to building blocks which can be rapidly assembled at a location where there is a need fur a temporary structure and afterward, when the need has passed, can as rapidly be dismantled. Once dismantled, the blocks can be shipped at relatively low cost to a new location and reused.
BACKGROUND OF THE INVENTIONWhen a disaster occurs such as a hurricane or a fire, there are often injuries and loss of life as well as damage and destruction of buildings. Many buildings such as houses, schools and factories must be rebuilt quickly to avoid a prolonged disruption in the lives of the survivors However, in most cases, existing structures are not rebuilt quickly. Rather, there are usually long delays before new structures are constructed and ready for occupancy.
I have invented building blocks which are suitable for use in temporary structures. The blocks are composed of lightweight material such as polypropylene or other polymeric material so that the blocks can be carried and lifted easily by hand. A crane or other machine for transporting and lifting the blocks into position is not required.
The blocks interlock to form the shell of a complete structure. Mortar or other bonding material is not required to hold the blocks in place. The blocks can be assembled into a structure quickly and later dismantled for use elsewhere with a minimum of delay and cost.
The blocks arc hollow to minimize their weight. The hollow interior of the blocks may be filled in the course of construction with a variety of materials. The interior may for example be filled with particles of insulating material or it may be filled with sand. Sand serves to increase the weight of the blocks and to increase the stability of the structure. Afterward, when the blocks are disconnected as the structure is being dismantled, the insulating material or sand can be poured out of the blocks in order to decrease their weight and to make them easier to handle.
Plugs are provided to close the openings through which the insulating material or sand is introduced into the interior of the blocks and openings are provided in the side walls of the blocks to which straps for drywall may be attached.
SUMMARY OF THE INVENTIONBriefly, the building block of my invention is adapted to interconnect with other like blocks to form a structure. Each building block is defined by a plurality of vertical walls; and top and bottom walls and has a thickness between oppositely facing exterior and interior surfaces of the walls. The interior surfaces define a hollow interior for, receipt and containment of particulate material therein. Each building block further has a first block connector composed of a vertically extending tongue or groove formed in at least one vertical wall. The block connector is adapted to interconnect with another like block connector in another building block disposed beside it and is provided with at least one opening through which particulate material may be selectively introduced and extracted from the hollow interior.
The building blocks of the invention are described with reference to the accompanying drawings in which:
Like reference characters refer to like parts throughout the description of the drawings.
DESCRIPTION OF PREFERRED EMBODIMENTSWith reference to
Selective vertical walls have first block connectors in the form of either a tongue or a groove which mates with the tongue. End wall 18b, for example, has a first block connector in the form of a vertically extending tongue 30 and the other end wall 18a has a first block connector in the form of a vertically extending groove 32. The tongue is adapted to interconnect with a groove in an end of a second identical building block (not illustrated) placed adjacent to end 18b of the subject building block and groove 32 is adapted to interconnect with a tongue in an end wall of a third identical building block (not illustrated) placed adjacent to the other end wall of the subject building block
The top and bottom walls have second block connectors in the form of either a projection of a recess which mates with the projection In
Openings 41 are formed in side wall 14 to facilitate attachment of straps to which dry wall or wooden panels can be attached.
The thickness of the vertical and the top and bottom walls of the building block should preferably be no more than that necessary to provide sufficient strength to maintain a structure in which the build block is a part intact. Thicker walls will not only add to the cost of construction of the block but also to its overall weight. A heavier block will lack the advantage of a lighter block as a structure is being assembled such as ease of handling and lower cost but will lack the advantage of ease of handling while the structure is being disassembled after it is no longer required.
As a structure is being constructed the blocks will be filled so that the filling, if it is strong in compression, such as compacted sand, will add strength to the block. If the filling is weak in compression such as insulating chips, it will also be light weight and will not add appreciably to the overall weight of the structure. In such case, the walls of the block need. not be strong enough to support the weight of much more than the weight of block above it.
With reference to
The flat walls 46h and 52h of the corner building block define the exterior faces of the corner of a structure. The tongue and groove 44, 50 in the oppositely facing walls 46a and 52a fit into conforming grove and tongue, respectively, of adjacent non-corner building blocks in the same course as the just-described block 42.
The corner building block of

A pair of rectangular recess 82 is formed in the bottom wall for receipt of the projection of the building block on which the roof block is seated. An opening (not illustrated) is formed in the top wall through which particulate material is introduced into the hollow interior of the block. A hollow 84 is provided on the front wall of the block to which a strap may be attached.

It will be understood, of course, that modifications can be made in the structure of the building blocks described and illustrated herein without departing from the scope and put view of the invention as defined in the appended claims. For example the side walls of the tongues and grooves may be bevelled for a more secure fit between the two. Likewise the side walls of the projections and recesses may be bevelled for the same reason.
