Abstract
Description
- The invention relates to an apparatus for containing stacked objects, in particular objects of rectangular cross section, such as bricks and concrete blocks both solid and cavity (hereinafter referred to as concrete blocks) and also to a method of stacking and lifting such objects.
- In transporting concrete blocks to and around building sites a considerable amount of damage is often done to the blocks and this wastage is expensive. Damage to concrete blocks in a highly mechanised concrete block plant is minimised by using a very sophisticated form of pallet loading system. However, this system is relatively expensive and is in any case not suitable for use on the normal building site.
- The invention is directed towards providing an apparatus for containing concrete blocks, and a method of stacking and lifting the concrete blocks, that is robust, inexpensive, and easy to use.
- According to the invention there is provided a container characterised by a frame providing a pair of spaced parallel support surfaces for supporting opposed portions of objects spanning across between the surfaces, and means extending upwardly of the support surfaces in use to facilitate mechanical lifting of the frame, the frame providing an aperture between and above the support surfaces at at least one end thereof.
- The inventicr further provides a method of stacking and transporting objects, the method being characterised by the steps of forming a first layer by placing a plurality of elongate objects side by side on a support with the ends of each object projecting beyond the support, forming a stack of one or more other layers of the objects on the first layer, and relatively moving the stack and a container according to the invention so that the stack enters the aperture and the ends of the objects of the first layer rest on the support surfaces.
- Also according to the invention there is provided an apparatus for containing stacked concrete blocks characterised by a cage having a base, a rear side, an open front side, and two end sides, the base having a cut-out slot of rectangular shape the open mouth of the slot being adjacent to the open front side, thus communicating directly with the said front side. The width of the slot is less than the largest lineal dimension of one of the concrete blocks. Preferably lifting lugs are provided on the cage to assist its transport by crane.
- The invention further provides a nethod of stacking and transporting concrete blocks characterised by the following steps:
- a) laying a plurality of concrete blocks end to end to form a bottom layer;
- b) laying a plurality of concrete blocks transversely side by side on the bottom layer to form a transverse layer;
- c) laying a plurality of concrete blocks side by side and end to end on the second layer to form a longitudinal layer.
- A further transverse layer followed by a further longitudinal layer may be laid until the requisite height of stack is achieved.
- By stacking the blocks in the way set out in the present invention, support for the stack ca; conveniently be provided by a plurality of the blocks themselves.
- The frame or cage is all that is then required safely and carefully to lift the stack and transport it from one location to another. It will be noted that there is no need for the time consuming and wasteful step of pallet- ising the blcoks before transport and then depalletising them on arrival at the required location.
- The invention will be more clearly understood from the following description of an embodiment thereof given by way of example only with reference to the accompanying drawings in which:
- Fig. 1 is a perspective view of a cage according to the invention,
- Fig. 2 is a perspective view of a number of concrete blocks stacked in accordance with the method of the invention, and
- Fig. 3 is a.sectional view in the direction of the arrows III-III of Fig. 1, the concrete blocks of Fig. 2 being shown by the interrupted lines.
- Referring to the drawings there is provided a cage having a base 1 a
rear side 2end sides 3 and an open front side 4. The base 1 is formed from a plate and has a cut-outslot 5 of substantially rectangular shape, an end plate 6 andside furcations 7. Therear side 2 and theend sides 3 are of lattice framework construction.Lifting lugs 8 are provided. - Prior to using the cage to lift stacked concrete blocks, in this example solid concrete blocks, the concrete blocks are stacked as illustrated in Fig. 2.
- Two
concrete blocks 9 are laid end to end to form a bottom layer, indicated generally by thereference numeral 10. A layer ofblocks 9 is then laid transversely side by side and the bottom layer to form a transverse layer, indicated generally by thereference numeral 11. A further layer ofblocks 9 is then laid side by side and end to end on thelayer 11 to form a longitudinal layer indicated generally by thereference numeral 12. A furthertransverse layer 11 is laid on top of thelongitudinal layer 12 and so on until the requisite height of stacked blocks is achieved. It will be appreciated that the top layer of blocks may be either atransverse layer 11 or alongitudinal layer 12. - With the blocks stacked as illustrated in Fig. 2 the front side 4 of the cage is offered up to the
blocks 9. Thefurcations 7 are solid underneath the lowermosttransverse layer 11 and on both sides of thebottom layer 10 until the cage embraces the blocks. The cage may then be lifted in conventional manner, its end plate 6 andside furcations 7 bearing against the bottom of the lowermosttransverse layer 11 thus lifting thestacked blocks 9. The cage may then be placed on a lorry for transport to site, where it is unloaded. Theblocks 9 may remain in the cage on site until required for use thus protecting theblocks 9 or alternatively the cage may be removed. Needless to say when on site the cage may be used to transport theblocks 9 from plate to place. - It will be appreciated that although the present invention solves the particular problem of careful handling of blocks on a building site, it can also be usefully employed at other locations.
- The invention is not limited to the embodiment hereinbefore described above which may obviously be varied in constructional details.
