    A support tool, a kit and a method for temporary stabilisation of a wall and the use of said support tool
    Field of the Invention
    The present invention relates to a support tool capable of temporary stabilisation of a load-bearing wall and a method for stabilisation of a load-bearing wall.
    Background of the Invention
    A load-bearing wall must be sufficiently stabilised when making a hole in the loadbearing wall. The hole could be for a door.
    Currently, the act of stabilising a load-bearing wall is a two man job as the support equipment is heavy and the equiapment comprises many different parts. See fig. 1 for an example of the present prior art.
    Thus, there is a need for a method and equipment which can be performed and used by a single person, thereby lowering the overall cost and time consumed.
    Furthermore, the existing support equipment is invasive to the load-bearing wall, because with the equipment it is necessary to make several through-going apertures in the load-bearing wall which must then be patched after the hole in the wall is made. This increases costs and it is more time consuming.
    Thus, there is a need for a less invasive method and less invasive equipment.
    Object of the Invention
    It is an object of the invention to provide a tool and a method for temporary stabilisation of a wall that can be performed by a single person.
    Description of the Invention
    An object of the invention is achieved by a support tool for temporary stabilisation of a load-bearing wall. The support tool may comprise a top bar with a wall-facing end. The wall-facing end will, when part of the support tool is inserted into the loadbearing wall, face the load-bearing wall.
    DK 2018 70620 A9
    The support tool may comprise a distance bar extending perpendicularly from the wall-facing end. The distance bar will, when part of the support tool is inserted into the load-bearing wall, interact with the load-bearing wall.
    The distance bar may extend and be connected to a bottom bar. The distance bar may thereby define a crossbar height.
    The bottom bar may comprise a rest facing the top bar. The rest is adapted for the placement of a crossbar.
    The support tool may further comprise a pike extending perpendicularly from the distance bar in an opposite direction to the bottom bar. The pike is adapted for being inserted into a wall.
    The support tool is adapted for receiving a crossbar between the rest and the top bar, where the crossbar will rest on the rest. The crossbar will have a height similar to the crossbar height, defined by the distance bar. There may be a wedge inserted between the crossbar and the rest and/or the top bar in order to further secure the crossbar.
    The pike is to be inserted into the wall. The act of inserting the pike may be by force, i.e. by hammering on the rest of the bottom bar. The act of inserting may include an act of pre-drilling a bore for the pike.
    The pike will typically be inserted into the mortar of the wall as the mortar can be repaired easier than a brick.
    The bottom bar and the distance bar may be arranged perpendicular to each other as this will give the best connection between the support tool and the load-bearing wall.
    The entire support tool can be held in one hand as the support tool will typically not weigh more than 1-3 kg.
    At least three support tools are to be used for the temporary stabilisation of a loadbearing wall. The pikes of the at least three support tools are inserted into the load
    DK 2018 70620 A9 bearing wall, such that the rests are aligned at the same height and the top bars are aligned at the same height.
    The two outer support tools of the at least three support tools will define support end points.
    The crossbar may then be positioned on the rests. The crossbar may be further secured by one or more wedges or by cramps or by any other securing means.
    The load-bearing wall will afterwards be temporarily secured and part of the wall may be removed.
    The support tools have different purposes depending on the position of the support tools relative to the hole to be made in the load-bearing wall. There need to be at least two outer support tools which are positioned above and on either side of the hole to be made. There need to be at least one inner support tool positioned above the hole to be made. When the support tools are equipped with a crossbar and the wall is removed below the crossbar, then the force distribution will be distributed as follows:
    The part of the wall above the hole will distribute a force onto the pike(s) of the inner support tool(s). The force is distributed along the distance bar(s) to the top bar(s). The top bar(s) will distribute the force down onto the crossbar. The crossbar distributes the force to rests of the outer support tools on either side of the hole, and the force is distributed through the pikes of the support tools back to the load-bearing wall and thus, the load-bearing wall is temporarily stabilised.
    Thus, the purpose of the outer support tools is to distribute a force from the crossbar to the load-bearing wall and the purpose of the inner support tools is to distribute the force from the wall above the hole to the crossbar.
    As explained above, the support tool of the present invention is able to fulfil both purposes and this simplifies the process of stabilising the load-bearing wall.
    The support tool may hold a point load between 4-7 kN.
    DK 2018 70620 A9
    More support tools are used if the load is larger than the support tool point load.
    In some cases support tools are positioned on both sides of the load-bearing wall to further increase the overall load-caring ability.
    The above-mentioned work is all doable by a single person because the support tool is small and easy to handle. The crossbar may be made of carbon fiber, wood or metal, such as steel or aluminium.
    Furthermore, the stabilisation of the wall is not very invasive compared to the prior art described earlier, because only a part of the mortar of the wall is removed by the insertion of the pike.
    The crossbar may also be liftable by a single person. This will often be the case when the hole to be made in the load-bearing wall is for a door.
    The bottom bar may distal to the distance bar comprise an anvil for hammering the support to into the wall.
    The top bar may distal to the wall-facing end comprise a downwardly extending lip for restraining a crossbar, thereby preventing any lateral torsional buckling.
    In an aspect of the invention, the pike may be pointed. This will make the insertion of the pike into the load-bearing wall easier.
    In an embodiment, the pike may be blunt as the user may pre-drill a bore and therefore the amount of material the pike must displace will be limited.
    In an aspect of the invention, the top bar may comprise a cramp extending through a part of the top bar, such that the crossbar height is variable.
    The cramp may comprise a swivel shoe for engaging with the crossbar, a threaded rod extending through the top part to a head. The head may easily be engaged by a user and the turning of the head will move the swivel shoe up or down.
    DK 2018 70620 A9
    In an embodiment, the rest may comprise a cramp extending through a part of the rest, such that the crossbar height is variable.
    The cramp may comprise a swivel shoe for engaging with the crossbar, a threaded rod extending through the top part to a head. The head may easily be engaged by a user and the turning of the head will move the swivel shoe up or down.
    In an embodiment, the top bar and the rest may each comprise a cramp extending through a part of the top bar and the rest, such that the crossbar height is variable.
    Each cramp may comprise a swivel shoe for engaging with the crossbar, a threaded rod extending through the top part to a head. The head may easily be engaged by a user, and the turning of the head will move the swivel shoe up or down.
    In an aspect of the invention, the support tool is made of a metal.
    The support tool may be made of steel, which is a strong material
    The support tool may be made of aluminium, which is lightweight and easy to handle.
    The support tool is made of carbon fiber, which is a light-weight and strong material.
    In an aspect of the invention, the pike may be directly opposite to the bottom bar. This makes it easier to insert the pike into a wall, because the bottom bar can be used as an anvil for hammering,
    Furthermore, this positioning gives a better force distribution and an improved connection with a wall.
    An object of the invention is achieved by a method for temporary stabilisation of a load-bearing wall. The method may comprise one or more acts of:
    - providing support tools;
    - inserting the pikes into a wall face;
    DK 2018 70620 A9
    - positioning a crossbar between the rest and the top part of the support tools.
    As an example:
    The pikes of at least three support tools are inserted into the load-bearing wall, such that the rests are aligned at the same height and the top bars are aligned at the same height.
    The crossbar may then be positioned on the rests. The crossbar may be further secured by one or more wedges or by cramps or by any other securing means.
    The load-bearing wall will afterwards be temporarily secured and part of the wall may afterwards be removed below the inner support tool(s).
    An object of the invention is achieved by a kit configured for temporary stabilisation of a load-bearing wall. The kit may comprise at least two T-shaped tools and one or more Z-shaped tools.
    Each T-shaped tool may comprise a T-leg extending perpendicularly from a T-foot, thereby dividing the T-foot into a T-rest end and an opposite T-pike end.
    The T-rest is adapted for the placement of a crossbar.
    The T-pike end is adapted for insertion into a wall. The T-pike end may have a pointed end as this will ease the insertion of the T-pike end into the wall.
    Each Z-shaped tool may comprise a Z-foot with a Z-pike end and a Z-leg extending perpendicularly from the Z-foot.
    The Z-shaped tool may comprise a Z-bar extending from the Z-leg in an opposite direction relative to the Z-pike end.
    The Z-pike end is adapted for insertion into a wall. The Z-pike end may have a pointed end as this will ease the insertion of the T-pike end into the wall.
    DK 2018 70620 A9
    The Z-bar is adapted for interacting with a top part of the crossbar.
    The Z-bar may be extending perpendicularly from the Z-leg as the crossbar will typically have a flat top part, and thus the interaction between the Z-leg and the crossbar is increased.
    The Z-bar may have a downwards extending Z-lip distal to the Z-leg for further restraining the crossbar, thereby preventing lateral torsional buckling.
    In an aspect of the invention, the method may further comprise one or more acts of:
    - providing a kit comprising at least two T-shaped tools and one or more Z-shaped tools.
    - inserting the Z-pike ends of the one or more Z-shaped tools into a wall face such that the Z-bars are aligned at a first common height;
    - inserting along a second line at least one T-pike end on each side of the one or more Z-shaped tools into a wall face, such that the T-rest ends are aligned at a second common height; and
    - positioning a crossbar between the rests and the top bar of the at least two support tools and the first ends of the one or more T-shaped tools.
    As an example:
    Z-pike ends are inserted into the load-bearing wall along a line, such that the Z-bars are aligned at a common height.
    At least one T-pike end of the one or more T-shaped tools is inserted into the wall face on each side of the one or more Z-shaped tools, such that the T-rest ends are aligned at a second common height.
    A crossbar may then be positioned on the T-rest ends. The crossbar may be further secured by one or more wedges or by cramps or by any other securing means.
    The load-bearing wall will afterwards be temporarily secured and part of the wall may be removed below the Z-shaped tools.
    DK 2018 70620 A9
    When the at least two T-shaped tools and the one or more Z-shaped tools are equipped with a crossbar and wall is removed below the Z-shaped tools, then the force distribution will be distributed as follows:
    The part of the wall above the hole will distribute a force onto the Z-pike end(s) of the Z-shaped tool(s), the force is distributed along the Z-leg (s) to Z-bar(s), which will be forced down onto the crossbar. The crossbar distributes the force to T-rest end of the T-shaped tools on either side of the hole and the force is distributed through the Tpike ends of the T-shaped tools back to the load-bearing wall and thus, the loadbearing wall is temporarily stabilised.
    An object of the invention is achieved by use of a support tool for temporary stabilisation of a load-bearing wall.
    An object of the invention is achieved by use of a kit comprising at least two T-shaped tools and one or more Z-shaped tools.

    Fig. 1 illustrates a prior art tool for stabilisation of a load-bearing wall 80.
    The prior art tool uses several parts and a flange going through the upper and lower parts of the load-bearing wall 80. This is an invasive technique and it is time consuming because two persons are needed in order to manoeuvre the prior art tool into place.
    Fig. 2 illustrates a schematic of a support tool 10 for temporary stabilisation of a load-bearing wall 80 (not shown). Fig. 2A and 2B discloses side views which are turned 90 degrees relative to each other.
    The support tool 10 comprises a top bar 20 with a wall facing end 22, which will face the load-bearing wall 80, when the support tool 10 is intended use.
    The support tool 10 comprises a distance bar 30 extending perpendicularly from the wall-facing end 22 to a bottom bar 40. The distance bar 30 and the bottom bar 40 are arranged perpendicular to each other.
    The length of the distance bar 30 defines a crossbar height 12.
    The bottom bar 40 has a rest 42, where a crossbar 90 (not shown) is to be positioned.
    The bottom bar 40 has opposite to the 42 and extending beyond the distance bar 30 a pike 44 for insertion into a wall face 82(not shown) of the load-bearing wall 80(not shown).
    Fig. 3 illustrates a detailed support tool 10 for temporary stabilisation of a loadbearing wall 80 (not shown). Fig. 3A and 3B discloses a side view and a top view of the support tool 10.
    The support tool 10 comprises a top bar 20 with a wall-facing end 22, which will face the load-bearing wall 80 when the support tool 10 is used.
    The support tool 10 comprises a distance bar 30 extending perpendicularly from the wall-facing end 22 to a bottom bar 40. The distance bar 30 and the bottom bar 40 are arranged perpendicularly to each other.
    DK 2018 70620 A9
    Opposite to the wall-facing end 22, the top bar 20 has a downwards extending lip for further restraining the crossbar, thereby preventing lateral torsional buckling.
    The length of the distance bar 30 does not define a crossbar height 12, because the support tool 10 further comprises a cramp 50 on the top bar 20 and the bottom bar 40.
    The cramp comprises a swivel shoe and a threaded rod extending from the swivel shoe through the top bar 20 or the bottom bar 40 to a head which is rotatable such that the swivel shoe may be moved vertically. This makes the cross bar height adjustable.
    The bottom bar 40 has a rest 42, where a crossbar 90 (not shown) is to be positioned.
    Opposite to the rest 42 and extending beyond the distance bar 30, the bottom bar 40 has a pike 44 for insertion into a wall face 82 (not shown) of the load-bearing wall 80 (not shown).
    The rest 42 has an extent which is larger than the top bar 20.
    The rest 42 has a downwards extending lip forming an anvil for hammering the support tool into a wall face.
    Fig. 4 illustrates a schematic of a T-shaped tool 70 for temporary stabilisation of a load-bearing wall 80(not shown). Fig. 3A and 3B disclose side views which are turned 90 degrees relative to each other.
    The T-shaped tool 70 comprises a T-foot 72 with a T-pike end 76 for insertion into a wall face 82 (not shown) of the load-bearing wall 80 (not shown).
    The T-shaped tool 70 comprises a T-rest end 78 opposite to the T-pike end 76. The Trest end 78 is adapted for holding a not shown cross bar 90.
    The T-shaped tool 70 further comprises a T-leg 74 extending perpendicularly to the Tfoot 72, thereby dividing the T-foot into the T-pike end 76 and the T-rest end 78.
    DK 2018 70620 A9
    The T-leg 74 will, when the T-pike end 76 is inserted into the wall 80 (not shown), directly interact with the wall face 82 (not shown).
    Fig. 5 illustrates a schematic of a Z-shaped tool 62 for temporary stabilisation of a load-bearing wall 80 (not shown).
    The Z-shaped tool 62 comprises a Z-foot 64 with a Z-pike end 65 for insertion into a wall face 82 (not shown) of the load-bearing wall 80 (not shown).
    The Z-shaped tool 62 further comprises a Z-leg 66 extending perpendicularly from the Z-foot 64.
    The Z-shaped tool 62 further comprises a Z-bar 68 extending from the Z-leg 66 in an opposite direction relative to the Z-pike end 65. The Z-bar 68 is adapted for interacting with a top of a not shown crossbar 90.
    Fig. 6 illustrates four support tools 10A, 10B, 10C, 10D positioned in a loadbearing wall 80 before a part of the wall is removed.
    The inner support tools 10B, 10C are positioned above the hole to be made, because these inner support tools 10B, 10C will distribute the weight, from the wall above the hole to be made, to a crossbar 90.
    The outer support tools 10A, 10D are positioned at a lateral distance to the hole to be made, because these outer support tools 10A, 10D are to distribute the force from the crossbar 90 to the load-bearing wall 80.
    The pikes 44 (not shown) are all inserted into the wall face 82 at the same height, such that the rests 42 are positioned at a first common height and the top bars 20 are positioned at a second common height.
    The crossbar 90 is positioned between the top bars 20 and the rests 42 of the bottom bars 40. The crossbar 90 may be further secured by wedges or cramps.
    DK 2018 70620 A9
    Fig. 7 illustrates a kit 60 positioned in a load-bearing wall 80 after a part of the wall is removed. The kit 60 comprises two T-shaped tools 70A, 70B and two Z-shaped tools 62A, 62B. The T-shaped tools 70A, 70B and the two Z-shaped tools 62A, 62B are equipped with a crossbar 90.
    The Z-shaped tools 62A, 62B are positioned above the hole as these Z-shaped tools 62A, 62B will distribute the weight from the wall above the hole to the crossbar 90.
    T-shaped tools 70A, 70B are positioned at a lateral distance from the hole as these Tshaped tools 70A, 70B are to distribute the force from the crossbar 90 to the loadbearing wall 80.
    Fig. 8 illustrates a method 100 for temporary stabilisation of a load-bearing wall 80.
    The method comprises one or more acts of:
    - providing 200 support tools 10;
    - inserting 300 the pikes 44 into a wall face 82; and
    - positioning 400 a crossbar 90 between the rest 42 and the top part 44 of the support tools 10.
