Description

[0001] The present invention relates to an angle bracket for a wall mounting system. The invention also relates to a wall system for a building.

[0002] The construction industry is constantly evolving towards lighter products, i.e. products that use less energy during the manufacturing process and provide better insulation properties in order to save energy over the whole lifespan of the product. Furthermore, due to rising wages and availability of skilled construction workers, it is also desirable that the effort needed by on-site workers is as limited as possible, considering both the general speed of construction and the necessity to reduce the need for labour on-site.. Therefore, there is a tendency towards having increasingly larger elements prefabricated at locations other than the actual construction site. These large elements will be prefabricated at large workshops and similar locations, reducing the risk of changes to the overall construction plan due to the weather conditions experienced on-site.

[0003] When the prefabricated elements have been mounted and assembled, they will be transported by truck or similar vehicles to an actual construction site. At the construction site, a crane will handle the whole element in one part, and the time from arrival of the element at the construction site to the placing of the element in its final position is typically few hours. Such a reduced timeframe to reach the final position is desirable, but a number of related effects are also then to be taken into account. For example, if the individual parts of the elements are to be assembled on-site, these individual parts obviously need to be on-site well before they are needed. This entails a multitude of logistical issues such as transportation on-site requiring transport equipment, proper storing and generally keeping track of the location of the individual parts. Furthermore, the construction site itself needs to be larger simply because the area required for storage of the construction parts and / or elements to be used later needs to be larger both to incorporate storage and to provide transport to / from the storage area (e.g. turning areas and pick-up / drop-off loading areas).

[0004] The present invention addresses the above disadvantages and drawbacks of the prior art. More specifically, the present invention provides an improved angle bracket that facilitates preassembly of wall elements at a different location than the construction site.

[0005] The present invention also provides a wall system of preassembled wall elements that, on arrival to the construction site, comprises means for attaching the wall elements to the floor.

[0006] In a first aspect, the present invention provides an angle bracket for a wall mounting system, the angle bracket comprising a first mounting section arranged and defining a first mounting plane and a longitudinal axis, the first mounting section having a first end section, a first and second edge section, and a first side and a second side. The angle bracket further comprises a second mounting section defining a second plane, the second mounting section having a second end section and first and second edge sections, and a first side and a second side, the second mounting section being arranged substantially perpendicularly to the first mounting section via a common section, wherein at least one of the first and / or second edge sections of the first mounting section comprises a fixation section projecting from the edge sections, the fixation sections defining a first fixation side and a second fixation side, where the fixation section is arranged by bending it in such way that the second side of the first mounting section faces the second side of the fixation section, where the fixation section is being arranged in a fixation plane parallel to the first plane, and where the fixation plane is arranged at a distance from the first plane.

[0007] In this way, a fixation guide is provided for fixating a construction element, e.g. a vertical column of a wall. The fixation guide is created by the fixation section being bent approximately 180 deg. and thus forming a stop preventing the construction element from being removed from the fixation guide in a direction perpendicular to the second plane. The inner side of the bent of the fixation sections, i.e. the curvature of the second side of the fixation section, meaning the extension of the second side of the first section, forms a stop in a direction perpendicular to the longitudinal axis of the first mounting section. In this way, it is achieved that the fixation guide is arranged to keep the construction element in a desired fixed position where the construction element could be e.g. an H-profile or an I-profile. Furthermore, the fixation guide is open near the first end of the first section, and hence it is possible simply to slide a construction element into the fixation guide of the angle bracket. In a similar manner, it is possible to slide the fixation guide of the angle bracket onto a construction element. In this way, high flexibility during the mounting process is achieved, enabling both wall manufacturers and construction workers to plan their work in the most efficient way.

[0008] Moreover, the distance between the first plane and the fixation plane may be 1mm-10mm, or more preferably 1.25mm-8mm, or most preferably 1.5mm-5mm.

[0009] In this embodiment, and in other embodiments, the first plane lies onto the second surface of the first mounting section, and the fixation plane lies onto the second surface of the at least one fixation section. Hence, the distance between the two planes is in fact the distance between the second side of the first mounting section and the second side of the fixation section.

[0010] The second mounting section may comprise at least one anchoring hole for anchoring the angle bracket to the foundation or floor.

[0011] In this way, the angle bracket may be anchored, i.e. affixed to the ground, floor or foundation.

[0012] Furthermore, the at least one anchoring hole in the second mounting section may have a diameter of 6mm-30mm, or more preferably 7mm-25mm, or most preferably 8mm-14mm.

[0013] In this way, the angle bracket and hence the wall that the angle bracket supports may be, or are, attached to the floor.

[0014] In an embodiment, the at least one hole in the second mounting section may be named an anchoring hole but is to be understood that the hole is a hole for any kind of fixation of the angle bracket to something else. Anchoring is typically used in the context of affixing the angle bracket to a floor i.e. the ground or foundation or other strong material, hence the term "anchoring". The at least one anchoring hole may be an elongated hole, i.e. a long hole. The elongated hole may be measuring up to 30mm at its longest dimension.

[0015] In addition, the first mounting section may comprise at least two holes for anchoring the angle bracket to the foundation or floor.

[0016] In this way, a strong anchoring of the angle bracket to the floor can be achieved. Having three holes and hence three anchoring points ensures that even when the wall is subjected to storms, the angle bracket will continue to be anchored to the floor. Thus, the bracket is not only fixed to the ground or floor but capable of withstanding stress imposed on the wall held by the bracket, e.g. withstanding the forces imposed on the wall during a storm. The angle bracket can withstand a load of more than 5kN, e.g. 17kN.

[0017] In an embodiment, the distance from the centre of a first anchoring hole to a second anchoring hole may be at least 50mm. In this way, a good distribution of the forces applied to the floor via the anchoring holes is achieved. Hence, the maximum possible load to be applied on the angle bracket can be fully transferred to / imposed on the floor. Thus, when having a strong floor, e.g. concrete, the bracket, and not external components, can determine the maximum load.

[0018] Further, the fixation section and / or the first section may comprise at least one fixation hole for receiving a screw or nail to be inserted into the part of the vertical column arranged between the fixation section and the first section.

[0019] In this way, the screw or nail is positioned correctly to achieve the strongest connection between the vertical column and the angle bracket.

[0020] When positioning the construction element to be connected to the angle bracket between the fixation section and the first section and then screwing a screw through all three parts, a double shear connection is achieved. This is highly desirable since this is a significantly strong connection. The double shear connection primarily relies on the material in the parts and to a minor extent on the thread of the screw. However, in order to achieve the best double shear connection, it is desirable that the screw is driven through all three parts in a substantially perpendicular manner. Hence, in order to ensure this perpendicular positioning of the screw, it is advantageous to have holes in order to align the screw, i.e. a hole in the fixation part arranged substantially concentric with a hole in the first section.

[0021] Moreover, the at least one fixation hole may have a diameter of 2mm-10mm, or more preferably 2.5mm - 8mm, or most preferable 3mm - 6mm.

[0022] In this way, the fixation holes can match screws of 3mm-12mm, respectively, and thereby a strong connection is achieved.

[0023] In an embodiment, the distance from the at least one fixation hole to the edge of the fixation section may be three times the diameter of the fixation hole. For example, if the at least one fixation hole has a diameter of 4mm, the distance from the fixation hole to the edge of the fixation section should be 12mm. In this way, a load imposed on the hole does not cause the material surrounding the fixation hole to break before the hole i.e. the strength is determined by the material properties and not because a hole has been introduced.

[0024] In another embodiment, the height of the fixation section may be between 60mm and three times the diameter of the fixation hole. In this way, the material surrounding the fixation hole is strong enough to withstand the forces applied to the surrounding material via the fixation hole. The forces will typically be applied in a known direction, and hence more material will be present in this direction.

[0025] In yet another embodiment, the first mounting section may comprise a hole arranged concentrically with each fixation hole. In this way, a guide is achieved for receiving e.g. a screw that is inserted in the fixation hole and then screwed into the hole in the mounting section. Thus, the holes can be, or are, arranged in a manner to achieve a double shear connection for the part inserted between the fixation hole and the opposing hole in the first mounting section.

[0026] Also, the fixation section may have an extension along the longitudinal axis of the first section of 25mm-60mm, or more preferably 30mm-55mm, or most preferably 35mm-50mm.

[0027] In this way, the fixation guide has an extension that fully supports the strength of the rest of the angle bracket as well as the connection between the angle bracket and the construction element. In particular, having an extension of more than 25mm, it is possible to insert two screws and thereby securely fixate the construction element.

[0028] In an embodiment, the height of the angle bracket may be 50mm-150mm, or more preferably 60mm-120mm, or most preferably 70mm-90mm.

[0029] In another embodiment, the width of the angle bracket may be 80mm-130mm, or more preferably 90mm-120mm, or most preferably 100mm-110mm.

[0030] In an embodiment, the shadow area of the fixation guide projected to the second side of the first mounting section may cover 20% - 95% of the flanges of the vertical column. The shadow area is seen in a direction perpendicular to the second surface of the first section. The fixation sections in combination with the second side of the first mounting section enclose 50% -95% of the flanges in the height of the fixation sections. In this way, the fixation elements have sufficient strength to fixate the flanges and hence the vertical column in relation to the angle bracket. When the flanges and the fixation sections in combination with the first mounting section form a strong connection, the anchoring of the angle bracket to the floor will be transferred efficiently to the wall element as a whole.

[0031] Furthermore, the distance from the second side of the fixation section to the second side of the first section may be 1mm-10mm, or more preferably 1.25mm-8mm, or most preferably 1.5mm - 5mm.

[0032] In an embodiment, the angle bracket may be made from pre-galvanized steel. In this way, the finalised bracket does not need an extra step in the manufacturing process after the punching of the final shape.

[0033] In an embodiment, the edge section and / or fixation section comprise(s) an embossment or an angled section. In this way, the edge section is more rigid.

[0034] The common section may comprise embossments. In this way, the bend in the common section and the sections to which the embossments extend is stronger and more reluctant to deviate from the initial shape and form when under load.

[0035] The invention also relates to a wall system for a building comprising a number of vertical columns having a first end and a second end, a number of boards attached to the columns, and an angle bracket connected to each of the vertical columns and affixed to the floor, wherein the fixation guide of the angle bracket is arranged to receive a part of the vertical column, e.g. flanges, and wherein the first section of the angle bracket is arranged between the vertical column and the board.

[0036] In this way, a finished wall section may be manufactured at a different site than where it is to be installed. This is made possible due to the fact that the angle bracket is simply slid in between the board and the vertical column, and then all parts are screwed together. The screws for connecting the vertical column, i.e. the flanges of the vertical column, to the angle bracket via the double shear connection mentioned above also extend into the board of the wall system. By way of the combination of the double shear connection and the screws connected to the board of the wall, a particularly strong construction is achieved. It is preferred that the tip of the screws does not project into the internal volume of the wall. The reason is that the workers will be installing, e.g. insulation, electrical wires, plumbing and the like, in this internal volume. During the installation process, the workers may be harmed if the screws project in the working area. Furthermore, the installations may be damaged by the screws, leading to both malfunctions and potentially highly hazardous situations, e.g. causing water damage from the plumbing or water pipes, or fire from the electrical systems.

[0037] In an embodiment, the boards may be OSB, chipboards, plywood or similar material. The boards may themselves be, or include / comprise, a vapour barrier.

[0038] Moreover, the thickness of the flange may be 0.5mm - 2mm smaller than the distance from the second surface of the first mounting section to the second surface of the fixation section. The distance from the second side of the first mounting section to the second side of the fixation section is also the depth of the fixation guide.

[0039] In this way, a gap is created, and hence the flanges of the vertical column may be inserted into the fixation guide, i.e. between the fixation section and the second side of the first mounting section, without the use of tools. Thus, no tools are necessary for this particular part of the assembling of the wall system.

[0040] Further, the wall system may also comprise a U-profile or an L-profile arranged on the floor in which the one end of the vertical columns is arranged, and wherein a wall of the U-profile or the L-profile is arranged partly between the angle bracket and the column.

[0041] Moreover, the vertical column may be affixed to the angle bracket by fixation means such as screws, nails or glue, or parts of the vertical column may be forced into the bracket, e.g. through holes in the bracket.

[0042] In addition, the fixation means may be screws, the screws being screwed through the bent section of the first section, through a part of the vertical column, e.g. the flanges of an I- or H-profile, through the first section of the angle bracket and into the board.

[0043] Furthermore, the tip of the screw may rest inside the board material.

[0044] In this way, the vertical column, the angle bracket and the board are fully connected, and the vapour barrier effect of the board is still maintained. When there is no risk of penetrating the vapour barrier, i.e. the board, it is possible to leave out the traditional vapour barrier. Furthermore, due to the following processes, including the wall, i.e. insulating the wall and installing all sorts of electrical installations in the walls, it is highly undesirable to have dangerous tips of screws placed freely inside the wall. The tips of the screws jeopardize not only the safety of the workers, but also the efficiency of the insulation and / or the integrity of the electrical and or water installations.

[0045] The present invention and its many advantages is described in more detail below by way of example only, with reference to the accompanying schematic drawings, which for the purpose of illustration show some non-limiting embodiments and in which: Fig. 1A shows a perspective view of a wall system using an angle bracket according to the present invention, Figs. 1B and 1C show two views of a single angle bracket in its mounted position, where the board is shown as a see-through board for illustrative purposes, Figs. 2A-2D show different views of an angle bracket according to the present invention, Fig. 3 shows a perspective view of an angle bracket to be mounted, Figs. 4A-4C show different views of an angle bracket according to the present invention inserted approximately halfway from its final position, and Figs. 5A and 5B show two views of the angle bracket in its fully mounted position.

[0046] All the figures are highly schematic and not necessarily to scale, and they show only those parts which are necessary in order to elucidate the invention, other parts being omitted or merely suggested. In particular, it is to be understood that Figs. 1 and 3-5 only show small sections of walls and not the full walls. All reference numerals are not present on all figures but will be present for each group of figures.

[0047] Figs. 1A-1C show an angle bracket 1 used in a wall assembly 100. The wall assembly 100 comprises a number of vertical columns 110 having a board 120 attached. The board 120 is shown as see-through in order to easily see the individual elements behind it. In reality, the board 120 may be made from a variety of materials, e.g. plywood, chip wood, wood fibre composites or the like. The vertical columns 110 are positioned in a U-profile 130. Each angle bracket 1 is connected to a column 110. The angle bracket 1 is positioned between the board 120 and the column 110. The angle bracket 1 is furthermore attached to a floor 50, and hence the angle bracket 1 connects the wall assembly 100 to the floor 50. It is to be understood that the floor 50 may be a concrete floor, a wooden floor or various types of floor used in both single story buildings and multi-story buildings. Figs. 1B-1C show a part of the wall assembly 100 only showing one angle bracket 1 attached to a vertical column 110 using screws 40. It is shown in Fig. 1B that 4 screws 40 are used, but it is to be understood that a different number of screws 40 may be used according to the specification of the necessary strength of the wall assembly. Fig. 1C further shows that the vertical column 110 comprises a first flange section 112 and a second flange section 114. The angle bracket 1 is attached to the floor 50 using one or two threaded rods 42 and nuts 44 (only one visible).

[0048] Figs. 2A and 2D show an embodiment of the angle bracket 1 having a first mounting section 2 and a second mounting section 3 connected to each other via a common section 4. The first mounting section 2 is arranged defining a first mounting plane FMP and a longitudinal axis LA, the first mounting section 2 has a first end section 5, a first and second edge section 6, 7, a first side 8 and a second side 9. The angle bracket 1 further comprises the second mounting section 3 defining a second mounting plane SMP, the second mounting section 3 having a second end section, first and second edge sections 11, 12, a first side 13 and a second side 14. The second mounting section 3 is arranged substantially perpendicularly to the first mounting section 2 via the common section 4. The common section 4 comprises two ribs 15 for strengthening the angle bracket 1.

[0049] The first and second edge sections 6, 7 of the first mounting section 2 each comprises a fixation section 16, 17 projecting from the edge sections 6, 7. The fixation sections 16, 17 define a first fixation side 18 and a second fixation side 19, where each fixation section 16, 17 is formed by bending the projection from the edge sections 6, 7 in such way that the second side 9 of the first mounting section 2 faces the second side 19 of the fixation sections 16, 17. In other words, the second side 19 of the fixation sections 16, 17 is in fact a continuation of the second side 9 of the first mounting section 2. The fixation sections 16, 17 are arranged in a fixation plane FP parallel to the first mounting plane (first plane) FMP, where the fixation plane FP is arranged at a distance d from the first mounting plane FMP. The second mounting section 3 of the angle bracket 1 further comprises a number of holes 22 in the first mounting section 2 for receiving anchoring means (not shown) in order to anchor the angle bracket 1 to the floor 50.

[0050] Fig. 2B shows the angle bracket 1 seen from above, i.e. perpendicularly to the second mounting plane SMP. It is shown that the fixation plane FP, i.e. the plane wherein the fixation sections 16, 17are arranged in parallel to the first mounting plane (first plane) FMP. Hence, a fixation guide FG is created between the second side 9 of the first mounting section 2 and the second side 19 of the fixation sections 16, 17. In this embodiment, the fixation section 16, 17 comprises holes 23 arranged concentrically with holes 21 in the first mounting section 2. In this way, it possible to ensure that mounting means, e.g. screws (not shown), are inserted in a way substantially perpendicularly to both the first mounting section 2 and the fixation sections 16, 17. The anchor holes (22 as shown in Fig. 2A) are shown having a distance AHD between them. The distance AHD may be approximately 50mm or more, in order to ensure that the floor or foundation is capable of withstanding the forces applied.

[0051] Fig. 2C shows the angle bracket 1 seen from the side having the holes 23 indicated by dotted lines. It is shown that also in this view the holes 23 in the fixation sections 16, 17 are aligned in a concentric manner with the holes 21 in the first mounting section 2. It is shown that the common section 4 comprises a rib 15 for strengthening the angle bracket 1. The second mounting section 3 comprises a number of holes 22 arranged for receiving e.g. anchoring means (not shown).

[0052] Fig. 2D shows another view of the angle bracket 1 in particular indicating the dimensions of the angle bracket 1. The overall height OAH of the angle bracket 1 is the distance from the second mounting section 3 to the top of the first mounting section 2. The fixation sections 16, 17 have a fixation height FH. The distance measured from the inside the bent part of the second side 19 of the first fixation section 16 to the inside of the bent part of the second side 19 of the second fixation section 17 defines the fixation width FW. The fixation width FW, the fixation height FH, the distance from the second side 9 of the first mounting section 2 to the second side 19 of the fixation sections 16, 17 (this distance is also shown in Fig. 4C as the FGD fixation guide depth) define the fixation guide FG (shown in Fig. 2B). The extension of the fixation section 16, 17 towards the centre of the first mounting section 2 is shown as the fixation section width FSW. In Fig. 2D, it is shown that small cut-outs 30 are located under the fixation sections 16, 17. These cut-outs 30 facilitate a smooth transition of the projections from the edge sections 6, 7, the projections forming the fixation sections 16, 17.

[0053] Fig. 3, Figs. 4A-4C and Figs. 5A-5B are highly schematic drawings showing a small part of a wall assembly 100 placed on a table 150. It is to be understood by the skilled person that the table 150 is merely to indicate a support during the assembly of the wall assembly 100. Since the board 120 is stiff, it may be possible to use a lathe or raft as a support only at the end where the angle bracket 1 is to be mounted. However, in a working environment in which the height is at an optimal level, the board 120 will be placed on the table 150 (or a similar surface), and the vertical column 110 will be fixed to the board 120 without screwing together an end section of the vertical column 110 to the board 120. In this way, it is possible to slide the angle bracket 1 in between the board 120 and the vertical column 110, i.e. pushing the angle bracket 1 in the direction of arrow A1. Flanges 111 on the vertical column 110 slide into the fixation guide FG, and the first side 8 of the first mounting section 2 slides in contact with the board 120. The second mounting section 3 acts as a stop when the angle bracket 1 is fully installed between the vertical column 110 and the board 120, rendering it possible to carry out the assembly process. In this way, the assembly is much easier and may be carried out in a simple way using simple tools. In the present embodiment, the flanges 111 are made of double-layered material. In this embodiment, the flanges 111 project 40mm from the body of the vertical column 110. The fixation sections 16, 17 cover 20% to 95% of the flange 111 measured perpendicularly to longitudinal axis in a plane parallel to the fixation plane FP. In the present embodiment, the fixation sections 16, 17 overlay the flanges 111 with approximately 50% of the flange 111 measured as described above. In other words, the fixation guide FG encloses more than 80% of the area of the flanges 111 of the vertical column 110 measured in the height of the fixation sections 16,17. The term vertical column refers to the position of the column in its mounted state e.g. as shown in Fig. 1A. Hence, the meaning is the same when referring a column and not necessarily a vertical column. This is in particular relevant during the mounting process of a wall element comprising a number of columns.

[0054] Figs. 4A-4C show in three views that the angle bracket 1 is halfway inserted between the board 120 and the vertical column 110. It is seen that the flanges 111 have been received in the fixation guide FG.

[0055] Fig. 4C shows how the flanges 111 of the vertical columns are positioned in the fixation guide FG. The flange thickness FT is shown leaving a gap G on either both sides of the flanges 111 or just one side of the flanges 111. The fixation guide depth FGD minus the thickness of the flange 111 give the total gap G. In the present figure, it is shown that there is a gap on each side of the flange 111wich might be the case when the column with its flanges is installed, but it is similarly likely that the gap is only present at the one side of the flanges 111. When the gap is only present on the one side of the flanges 111 it is due to the column 110 and hence the flanges 111 being forced against the second side 9 of the first mounting section or forced against the second side 19 of the fixation sections. In this embodiment the angle bracket 1 comprises three anchoring holes 22 each spaced apart a distance AHD of at least 50mm.

[0056] Fig. 5A and Fig. 5B show that the angle bracket 1 is fully inserted between the column 110 and the board 120, i.e. the angle bracket 1 is pushed so that the second mounting section 3 abuts the edge section of the board 120. A part of the flanges 111 of the vertical column 110 are received in the fixation guide FG, i.e. a part of the flanges 111 are positioned between the fixation sections 16, 17 and the first mounting section 2. The screws 40 are being screwed through the holes 23 in the fixation sections 16, 17, through the flanges 111, through the holes (21 but not visible) in the first mounting section 2 , and finally the screws 40 are screwed in the board 120 in such way that the tip of the screw rests inside the board 120.
