FIELD OF THE INVENTION
[0001] This invention relates to a method and means for constructional work.
BACKGROUND OF THE INVENTION
[0002] Interlocking blocks of various types for both toys and in building constructions
are well known.
OBJECT OF THE INVENTION
[0003] It is an object of the invention to provide blocks for constructional work.
THE INVENTION
[0004] A method of building according to the invention includes the steps of locating a
plurality of open-top and open-bottom containers in a predetermined pattern, introducing
a filler material in the containers and allowing the material to settle or set.
[0005] The containers are preferably disposable and may be removed after the mixture has
set or may be permitted to remain in position for a time.
[0006] In a preferred form of the invention the disposable containers are cardboard boxes
and they may be laid in their vertical or horizontal condition, but in whichever condition
they are used, the tops and bottoms are removed.
[0007] The containers may be provided with vertical slots adapted to receive an edge of
the container laid thereabove. These slots may be of predetermined depth so that they
assist in the proper location of the containers. In fact, the slots may be such that
they comprise the sole means of ensuring that the wall being built is vertical, once
the foundations have been accurately laid.
[0008] According further to the invention tie rods are provided which span the containers
and these may have extruding portions adapted to key in the plaster which may be applied
after removal of the cardboard. It will be appreciated that the plaster may be applied
to the cardboard.
[0009] In addition, vertical ties may be provided particularly at the top layer of the structure
so as to provide a fixing for a wall plate or roofing elements.
[0010] The slots may be located midway on the top edges of the containers so that the end
edges of the containers for location at the next layer will be staggered in relation
to the layer below.
[0011] The cardboard containers may be specially treated for waterproof, pestproof and other
properties so that they may be substantially permanent and it will be appreciated
that they may be painted. The carboard may be treated with a cementitious mixture.
For very low cost building, the building mixture may be sand or soil mixed with lime,
cement, an aqueous polymer emulsion or the like.
[0012] According to another aspect of the invention a building element comprises a box shaped
body having an open top and an open bottom, and at least some of the sidewalls including
formations for engaging the edges of the side walls of adjacent blocks.
[0013] In a preferred form of the invention the formations comprise slots which extend for
a short distance from the free edges of the side walls. Preferably the slots are formed
on opposed side walls and the width corresponds with the thickness of the side wall.
The blocks may include openings in opposed side walls to constitute connections between
adjacent blocks.
[0014] Preferably the blocks are formed for use in building construction in which case a
settable material may be filled in the space between the walls. Alternatively the
blocks may be formed as toys in which event they may be reusable.

DESCRIPTION OF PREFERRED EMBODIMENTS -
[0016] Referring to the drawings a building element 10 comprises a box shaped body having
side walls 12.
[0017] In Figures 1 and 2 the height of the side walls 12 is greater than the width while
in Figure 3 at least two side walls 14 have a width which is greater than the height.
The side walls 12,14 each have two slots 16 extending inwardly from the free edge
thereof. The width of the slots 16 correspond substantially to the thickness of the
walls. The slots 16 are formed midway between the ends on opposed side walls and along
one face of the building element only.
[0018] The building elements 10 are formed from cardboard or the like material and have
openings 18 on opposed side walls. A building tie 20 formed with wire is locatable
in the slots 16 to strengthen the building element. Cutouts 21 are formed in the building
elements to drain off excess water during building.
[0019] In use of the invention for building construction the building elements 10 are arranged
as seen in Figures 2 and 3 with ties 20 located in the slots 16. A settable material
is then poured into the space between the walls. The material flows through the opening
18 hence forming a continuous interconnected structure. If the building elements 10
are used as toys the ties 20 and the settable material are omitted so that the building
elements are reusable.
[0020] An advantage of the invention is that the building elements may be speedily assembled
with unskilled labour and the interlocking arrangement ensures that the assembly has
the correct dimensions.
1. A method of building including the steps of locating a plurality of open-top and
open-bottom containers in a predetermined pattern, introducing a filler material in
the containers and allowing the material to settle or set.

material which is filled in containers comprising cardboard boxes which are stacked
one upon the other and the material is allowed to set.
