Description

Adjusting screw for building walls

The invention relates to an adjusting screw for constructing walls and a method for constructing a wall using the adjusting screw according to the invention.

In modern house construction, walls are increasingly being erected as a finished component. In the context of this application, walls are understood to mean the boundaries of individual rooms, which are installed either as an interior wall within a house or as an exterior wall to protect the interior of the house and usually have thicknesses of between 10-16 cm in the case of interior walls and between 25 and 45 cm in the case of exterior walls . The walls can be made of different materials such as wood or plastic. The term wall also includes a so-called support wall, which merely represents the supporting framework of a wall and is completed in the erected, i.e. assembled state, using insulating materials and cladding. Such walls are also frequently referred to as timber stud walls.

In order to be able to erect walls as a finished component, the position for erecting the wall is first determined and marked according to the prior art. The floor is then measured and unevenness in the floor is compensated for by a so-called assembly threshold, which is screwed to the floor. Within the scope of this application, the above-mentioned unevenness in the floor refers to differences in height, which extend over the floor area, so that higher and lower points occur distributed over the floor area. These bumps can be several centimeters in some cases and are therefore responsible for unstable assembly, which means that it is essential to compensate for the bumps. In contrast to this, a flat surface is consequently a surface that has no higher and lower points, or where these are within a tolerance range. Craftsmen like to use the term “in the water” or level for a flat surface.

The mounting threshold is usually a wooden construction, which is weighed in using washers of different thicknesses in order to create a level support surface for the wall. An easy-to-shape swelling mortar is filled between the assembly threshold and the floor, which increases in volume as it hardens and closes the gap between the assembly threshold and the floor. Such a method according to the prior art has the disadvantage that the construction and weighing of the assembly sleeper is very complex and therefore time-consuming and for this reason represents a major cost factor when erecting a wall.

The object of the present invention is therefore to provide a solution for eliminating the disadvantage mentioned above.

This is achieved by the subject matter of the independent claims according to the invention. Advantageous embodiments of the invention are contained in the dependent claims.

The adjusting screw according to the invention for use in constructing a wall on an uneven floor surface has a threaded portion with a thread and a certain length, which is adapted to be screwed into the floor surface. The adjusting screw according to the invention also has a screw head which has a specific width and a flat bearing surface on a top side, the top side of the screw head being designed to serve as a bearing surface for the wall.

The screw head and the threaded section can be formed in one piece with each other. It is also conceivable that the adjusting screw is designed in several pieces, in particular in two pieces, for example in the form of a screw head and a threaded section. In this case, for example, a base body can be provided which has the screw shank with the threaded section and optionally a thread-free section and a head area. In such an embodiment, a support body can then be provided which is designed to be irreversibly or reversibly fastened to the base body and is fastened to it, for example in the head area. In particular, the base body can be welded, screwed or connected in some other suitable way to the support body in order to form the adjusting screw.

In this case, the screw head is advantageously of planar design both on an upper side and on a lower side. In this way, a distance from the top of the adjusting screw, ie the bearing surface, to the floor surface can be minimized, if desired.

In at least one embodiment of the invention, the adjusting screw on the underside of the screw head has a non-planar design, for example a conical shape. Using the adjusting screw according to the invention, a new method according to the invention for constructing walls is made possible. In a first method step (A), the position of the wall to be erected/built up is determined. This can be done, for example, by projecting the inside edge of the wall onto the floor surface. Subsequently, in method step (B), the surface is leveled (put into the water) to the highest point that is along the area where the wall is to be erected, so that an imaginary flat surface is created along the determined position of the wall, also referred to below as installation level. Preferably, the uneven floor surface is leveled along the determined position of the wall using a spirit level or a laser spirit level.

The position at which a wall to be erected is arranged in the erected state should be regarded as a position of the wall. If the underside of the wall to be erected is based on a flat surface that rests on the adjusting screws, the position of the wall in a horizontal direction is determined by the position of the adjusting screws in such a way that the wall rests on the adjusting screws at least partially, in particular over the entire surface got to. In a vertical direction, the position of the wall is defined by the bearing surfaces of the adjustment screws. This means that the bearing surfaces of the leveled adjustment screws define an erection level for this wall on its underside in an erected position. In a broader sense, the position of the wall also includes those areas related to the above definition of the wall, such as the area of the floor surface where swelling mortar or other layer of material is provided, or at the angle for fixing and securing the wall be provided.

Leveling is understood to mean in particular the alignment of the position of the wall, or the side of the wall to be placed on the adjusting screws, relative to the floor surface. In a preferred embodiment of the invention, this alignment is carried out in such a way that the leveled wall to be set has the minimum possible distance from the floor surface. This means that the leveling takes place on that, preferably horizontal, plane that is defined in the area of the wall to be erected by the highest elevation of the floor surface. In this embodiment, the wall, which is then arranged on the bearing surface of the adjusting screws, is therefore at a minimum distance from the floor surface. The distance from the bottom surface to the underside of the wall is determined by the height of the highest elevation in the bottom surface and/or a thickness of the screw head. When using a plurality of adjusting screws to create a level support surface, it is only necessary to ensure that the tops of the adjustment screws, ie the support surfaces, are above or at least at the same level as the highest one Unevenness in the area of the footprint of the wall or walls are arranged. This makes it possible to reduce the cost of materials, for example in the form of expanding mortar to support the wall on the floor surface.

In preferred embodiments of the present invention, the leveling is relative to the underside of the adjustment screws, the undersides advantageously having a flat surface in this embodiment. Depending on the specific geometry of the screw, leveling can also occur relative to the top of the adjustment screws or to another position on the screw, for example provided by markings or other features on the screw, on the screw, or in the screw .

It goes without saying that in other embodiments the leveling can also take place relative to the highest elevation or the topmost point of the floor surface in such a way that the installation plane defined by the bearing surfaces is offset vertically to the plane in which the highest elevation of the floor surface ends, and which runs parallel to the installation level. By leveling the installation level to a higher level, for example, a slope in the floor area can be compensated for, a slope can be generated, or a connection to neighboring objects, buildings or structures can be made possible or provided. In addition, by providing more void space between the underside of the wall or walls to be erected, the choice of materials for supporting and/or fastening and/or insulating the wall on the floor surface can be expanded.

In the case of a plurality of walls to be connected to one another, leveling is advantageously carried out at the top point or relative to the top point in the area of the intended position of the walls or the area spanned by the position of the walls or the installation level defined by the bearing surfaces of the adjusting screws. That plane which, in the desired orientation, runs through the uppermost point of the highest elevation of the floor surface, relative to which leveling is to take place, can therefore also be referred to as the leveling plane. In preferred embodiments of the invention, the leveling plane defined in this way runs horizontally, ie “in the water”. However, it is also conceivable that an inclined course of the leveling plane is provided.

In particular, leveling can take place in such a way that the erection level defined in this way has no points of intersection with the elevations of the floor surface in the area of a structure to be built, for example a house. Should an elevation of the floor surface protrude beyond the installation level, then, for example, laying a floor or any other later processing could be made more difficult, which is prevented according to the invention or several walls to be set and in particular their distance from a floor surface using one or more adjusting screws according to the invention and coordinated with one another. This may allow defining a common height for posing a plurality of walls.

It is also conceivable that the adjusting screws are provided in such a way that their bearing surfaces form a plurality of planes which are offset from one another in a vertical direction. In this way, for example, stair-like structures can also be provided for walls that do not have a flat underside but rather a more complex shape. In some embodiments of the invention, in a next method step (C), at least two of the inventive adjusting screws are mounted on the floor surface along the determined position of the wall such that the position of the underside of the screw heads of the adjusting screws corresponds to the leveled height. In a further step (D), at least one layer of material, for example expanding mortar or another filling material, is applied to the floor surface along the specific position of the wall. In the last method step (E), the wall is then set up on the expanding mortar and the adjusting screws in such a way that the wall rests on the at least two adjusting screws.

Alternatively, another material suitable for support, such as another load-bearing mortar, or also a non-load-bearing material, such as a filler or leveling compound and/or an insulating material or the like, can be used in the space below the wall to be erected. It is also conceivable that step (D) is carried out at a different point in time, in particular later, for example for subsequent filling of the space between the underside of the wall and the floor surface.

At least one intermediate layer can be provided in all embodiments between the adjusting screw and the wall. The intermediate layer can, for example, be designed to be at least partially limp and in particular in the form of a sealing strip or sealing element. In addition or as an alternative, the intermediate layer can at least partially have an inherent rigidity and can be designed, for example, in the form of a metal rail, a fitting and/or a plastic strip.

It is also possible that several layers of material, for example a combination of filling material and load-bearing material, are applied next to one another in layers and/or in sections in the space below the wall to be erected. In at least one embodiment of the invention, the intermediate layer can only be provided in the area of the adjusting screws, in particular on the upper side of the adjusting screws, ie the bearing surface.

In advantageous embodiments of the invention, a sealing layer, in particular a sealing strip, is provided at least in the area of the adjusting screws. In a method provided according to the invention, a sealing layer, in particular a sealing tape, is advantageously provided at least partially, preferably over the entire surface, in the area of the underside of a wall or walls to be placed, or this sealing layer is provided before introducing a leveling or filling compound between the adjusting screw and wall or applied to the underside of the wall. In this way, the tightness of the wall can be improved.

Using the method according to the invention, it is possible to avoid the time-consuming and costly construction of the assembly threshold and still be able to set up walls safely and quickly.

In other embodiments of the invention, the leveling according to method step (C) takes place relative to the top of the screw head or another area of the screw, for example a marking, a thread start or the like. In general, the adjustment of the screws or the leveling therefore takes place relative to a predetermined section or reference point of the adjusting screws, whereby this can also include a, preferably vertical, offset of the installation plane relative to the leveling plane.

In an advantageous embodiment of the adjusting screw according to the invention, the ratio between the length of the threaded section and the width of the screw head is between 1 and 2, preferably between 1.25 and 1.75 and particularly preferably 1.5. The ranges mentioned can be used to ensure that the width of the screw head is adequate in relation to the length of the thread. The heavier the wall to be erected, the wider the screw head must be and the longer and stronger the threaded section must also be. The correct dimensioning of the screw for most walls can therefore be achieved on the basis of the ratios mentioned.

In some embodiments of the invention, the length of the threaded section is equal to the length of the screw shank. In other embodiments of the invention, it is conceivable that the shank of the screw also has a section that is designed without a thread. Such a section is advantageously provided between the screw head and the threaded section. This also applies to a not planar design of the underside of the screw head, such as in the case of a conical screw head, in which case in particular the geometric shape of the underside of the screw can be interpreted as a threadless section in this case.

Furthermore, an embodiment of the adjusting screw according to the invention is advantageous in which the width of the screw head is at least 3 cm, preferably at least 5 cm and particularly preferably at least 7 cm and/or at most 16 cm, preferably at most 13 cm and particularly preferably at most 10 cm. The width of the screw head is defined by the widest point of the screw head. A minimum width of the screw head prevents the wall from being deformed by the screw head when it is placed on it. On the other hand, the screw head must not be too large, otherwise there is a risk that the screw head will protrude beyond the width of the wall in the case of particularly thin walls.

Similarly, the thread must also have a minimum thickness in order to be able to withstand the weight of the wall. A minimum thickness of 4 mm, preferably 6 mm, particularly preferably 8 mm is advantageous, with a maximum thickness of 20 mm, preferably 18 mm and particularly preferably 16 mm also being advantageous.

In a further advantageous embodiment of the adjusting screw according to the invention, it has a screw head drive in order to simplify the assembly of the screw. A screw head drive is a distinctive indentation or shape in the screw head that allows a suitable screwdriver or wrench to be used to drive the screw into the designated thread or non-threaded material. Common examples of screw head drives are slotted heads, hexagon sockets, square sockets, hexagon sockets, Phillips or hexalobular sockets (also called torx). Any form of screw head drive is conceivable for the adjusting screw according to the invention, as long as the upper side of the screw head remains flat and does not have to be curved. It is also conceivable that an adjusting screw according to the invention has two or more screw drives of the same type or of different types.

In an advantageous embodiment of the invention, the screw head drive is realized by two holes of a defined cross section in the screw head. In this way, it can be ensured that the appropriate tool, which has pegs that fit into the holes, can be applied in a non-slip manner, in that the pegs of the tool engage in the holes of the screw head drive, and that sufficient force can be transferred to the screw. In addition, it is possible using this embodiment to provide the smallest possible recesses on the top of the screw head in order to In an advantageous embodiment of the method according to the invention, the swelling mortar is applied in method step (D) in such a way that the adjusting screws form a depression in the surface of the swelling mortar. A sink describes a kind of bulge or indentation in the swelling mortar at the points where the screw heads are located, with no swelling mortar reaching the tops of the screw heads. In this embodiment, the wall is erected in method step (E) in such a way that the part of the swelling mortar which protrudes above the height of the adjusting screws is displaced. This embodiment has the advantage that it can be ensured in this way that there is sufficient swelling mortar underneath the wall to support the wall in the dried state and thus relieve the adjusting screws again and increase safety and stability.

In a further advantageous embodiment of the invention, at least one angle is provided for fastening and/or positioning the wall on the floor surface, with a first leg of the angle being fastened to the wall and a second leg of the angle being fastened to the floor surface. The at least one bracket is preferably mounted on the floor surface after method step (A). Fixing with the brackets is a reliable, simple and inexpensive way to keep the wall in the desired position over the long term.

A further advantageous embodiment of the method according to the invention is the use of a sealing tape. This is preferably applied between method steps (D) and (E) on the swelling mortar and the adjusting screws in such a way that there is no swelling mortar between the sealing tape and the adjusting screws. The sealing tape can be attached to the adjusting screws using a double-sided adhesive tape, for example. On the one hand, it prevents swelling mortar from swelling onto the top of the screw head of the adjusting screw when the wall is erected, which could result in an uneven contact surface on the screw head for the wall. On the other hand, the sealing tape ensures that there is no leakage in the wall, as a result of which the rooms to be separated by the wall would not be cleanly separated from one another.

In another embodiment of the invention, the sealing tape can also be applied after the wall has been erected in the transition between wall and floor and can be fastened both to the floor surface and to the wall in order to guarantee the tightness of the wall.

The method according to the invention is particularly suitable for walls, wall elements, wall elements connected to one another, or others in a vertical direction Wall elements are preferably free-standing or, at the time the described method is used, are free-standing or not completely framed.

While the present invention is particularly suitable and provided with regard to the steepening and adjustment of walls in timber construction, other areas of application are also conceivable. The use of the adjusting screws is equally suitable for setting up prefabricated concrete elements, other partition walls, or for leveling larger areas. Furthermore, it can also be used, for example, for the vertical adjustment of foundations, for example bucket foundations, or the like. For such an application, only the proportions of the adjusting screws, i.e. the ratio of screw head width to thread length, may have to be adapted to the relevant area of application.

The invention is explained in more detail below with reference to the accompanying figures. The figures show:

Illustration of method steps according to the invention for building a wall

1 shows an adjusting screw 10 according to the invention in a first embodiment. It has a round screw head 12 with a width b and a threaded section 11 with a length l. A thread is provided on the threaded section 11 which is configured to be screwed into a corresponding floor covering, for example concrete. The screw head 12 has a bottom 14 and a top 15 . The screw head 12 is connected to the threaded section 11 on the underside 14 . The top 15 (not shown in FIG. 1) of the screw head 11 is accordingly the side opposite the bottom 14 . Also provided in the screw head 11 is a screw head drive 13 , which in this embodiment consists of two holes of a specific cross section extending continuously from the top 15 to the bottom 14 . The two holes are arranged opposite each other on the screw head 11, with the threaded section 11 located. Using the screw head drive 13, the screw can be rotated and driven into a material. In other embodiments of the invention, it is also possible for the holes not to be continuous through the screw head.

In the embodiment shown, the threaded portion 11 and the screw head 12 are assembled from respectively different parts in order to form the adjustment screw 10 together. One could therefore speak of a two-part embodiment. However, one-piece embodiments of the invention are of course also conceivable, in which the screw head 12 and threaded section 11 are manufactured from one part. Likewise, FIG. 1 shows an embodiment in which the threaded section 11 is completely covered with a thread. The overall length of the screw would therefore be the sum of the thickness of the screw head 12 and the length l of the threaded section 11. Embodiments which have a threaded section 11 with a shank and a thread are also possible. For example, between the screw head 12 and the threaded portion 11, a thread-free portion with a predetermined length d - be provided - not shown in the figures. In such an embodiment, the overall length of the screw would then be the sum of the thickness of the screw head 12, the length l of the threaded section 11 and the length d of the unthreaded section. The length d of the unthreaded section can be chosen depending on the intended use of the adjusting screw 10 . It goes without saying that other thread types, for example with a plurality of thread sections alternating with thread-free sections and/or with varying thread strengths and the like, can also be provided. In particular, this can enable a suitable selection of the screw used depending on the material and the nature of the floor surface. FIG. 2 shows a further embodiment of the adjusting screw according to the invention, which largely corresponds to the embodiment shown in FIG differs. Instead of two holes, the screw head drive 13 shown in FIG. 2 has a known external hexagon. In addition, the adjusting screw 10 from FIG. 2 is shown in a different perspective, so that the upper side 15 of the screw head 12 in FIG. 2 can be clearly seen.

An advantage of the screw head drive 13 in the form of an external hexagon is that the top 15 of the screw head is designed to be continuous and does not have any holes and thus the load of the wall 20 (not shown) can be distributed evenly over the screw head. Another advantage is that no special tools are required for assembly, as external hex drives are widely used are. The disadvantage, however, is that, depending on the width b of the screw head 12, very large tools have to be used. In this case, the width b of the screw head 12 refers to the widest point of the screw head 12.

3a shows a schematic profile view of an uneven floor surface 30 on which a wall 20 (not shown) is built using the adjusting screw 10 according to the invention using the method according to the invention. It is easy to see that the floor surface 30 has bumps and thus higher and lower points. The highest point of the bottom surface 30 is referred to as the highest point 31 .

FIG. 3b shows a section of the bottom surface 30 shown in FIG. 3a. The unevenness has been exaggerated in order to be able to better illustrate the method according to the invention. Two brackets 50 can be seen, each of which is fastened in the bottom surface 30 and mark the position of the wall 20 (not shown) that is to be determined beforehand. The brackets 50 each have a first leg 51 which points vertically upward away from the bottom surface 30 . The wall 20 is later attached to them. In addition, the brackets 50 each have a second leg 52 (not shown), which extends into the plane of the drawing at a 90-degree angle to the first legs 51 and is fastened to the bottom surface 30 .

In addition, a leveling line 31a can be seen, which levels the floor surface 30 and is completely horizontal, thereby intersecting the highest point 31 . The leveling line 31a is thus “in the water”.

FIG. 3c also shows the section of the uneven floor surface 30 shown in FIG. 3b. Using the leveling line 31a, it is now possible to screw adjusting screws 10 according to the invention into the floor surface 30. These are screwed in until the undersides 14 of their screw heads 12 are level with the leveling line 31a. The adjusting screws 10 - 2 can be seen in the section shown - are driven into the ground at regular intervals that are not too large.

Applied swelling mortar 32 can be seen in FIG. 3d, which was applied to the floor surface 30 in one layer. The swelling mortar 32 protrudes in height above the upper side 15 of the screw heads 12 so that depressions 33 form at the points where the adjusting screws 10 are located, which depressions are in the swelling mortar 32 .

3e shows a sealing strip 40 (dashed line) which has been placed over the expanding mortar 32 and the screw heads 12 of the adjusting screws 10. FIG. An attachment of the sealing strip 40 on the screw heads 12 can, for example, using a double-sided adhesive tape can be ensured, so that the sealing tape 40 is attached to the screw head 12 over the entire width b of the latter.

Finally, in FIG. 3f it can be seen that the wall 20 was set up on the sealing strip 40 and thus on the expanding mortar 32 and the screw heads 12 . The part of the swelling mortar 32 that protruded above the screw heads 12 was displaced by the wall 20's own weight. The sealing strip 40 prevents swelling mortar 32 from reaching the top 15 of the screw heads 32 and thus also prevents the wall 20 from being set up at an angle, ie not horizontally.

Until the swelling mortar 32 hardens, the wall 20 is essentially supported by the screw heads 12 of the adjusting screws 10 . However, as the swelling mortar 32 hardens, it expands and gradually takes the load off the adjusting screws 10. As soon as the wall 20 is in the desired final position, it is fastened to the first leg 51 of the angle 50.
