Description

[0001] The present invention relates to a masonry profile clamp for fixating a masonry reference tool and a method for fixating a masonry reference tool using a masonry profile clamp.

[0002] The art of masonry is rooted in craftsmanship, with a primary focus on achieving precise horizontal alignments in the layers of brickwork. Traditionally, masons employ a masonry cord stretched between two masonry profiles as a control measure to ensure a level horizontal progression of brick layers. This method serves as a valuable reference for masons during the construction process.

[0003] While the use of a masonry cord is integral to the process, achieving uniformly attractive masonry construction involves additional complexities. In practice, a gauge rod or strip is additionally used having markings to indicate the desired spacing between bricks when constructing a brick wall. This tool, typically crafted from spare wood and marked with measurements for brick and mortar spacing, provides a reliable means of measurement. The gauge rod or layer strip is affixed, for instance, by nailing or screwing it into the masonry profile. The gauge rod or layer strip assists masons in maintaining a consistent thickness and height for each layer of bricks during the masonry process. By attaching the gauge rod or layer strip at the desired height on the masonry profile and using it as a reference, masons ensure that each new layer of bricks is laid evenly and at the correct height. The marked dimensions indicate the average size of bricks used in construction. The layer dimension, representing the average thickness of a brick plus the thickness of a mortar joint, is however challenging to get correct due to variations in brick sizes and mortar joint dimensions.

[0004] Throughout the construction process, masons routinely check alignment using the gauge rod in conjunction with the masonry cord, making adjustments as needed to maintain consistent horizontal alignment across the brick wall. For instance, when a specific height is reached, the gauge rod needs relocation on the profile and reattachment, a task that is time-consuming.

[0005] Furthermore, the manual determination of the average size and subsequent height marking on the gauge rod or layer strip by the mason introduces a level of subjectivity and variability. As a result, the current state of the art relies on time-consuming and labour-intensive processes for achieving both horizontal and vertical alignments in masonry construction.

[0006] Therefore, it is an object of the present invention to provide a masonry profile clamp for fixating a masonry reference tool, wherein a more efficient system is obtained for achieving horizontal alignments in masonry construction, or to provide at least an alternative masonry profile clamp.

[0007] According to a first aspect of the invention, the object of the invention is achieved by providing a masonry profile clamp for fixating a masonry reference tool, wherein the masonry profile clamp is attachable to a masonry profile to clamp onto the masonry profile extending within a clamping width of the masonry profile clamp, the masonry profile clamp comprising an elongated body extending in a longitudinal direction between o a first end having a first side portion extending in a transverse direction transverse to the longitudinal direction, and o a second end having a second side portion extending in the transverse direction transverse to the longitudinal direction, the second side portion being parallel to the first side portion; the elongated body comprising a reference tool guide arranged between the first end and the second end, the reference tool guide being configured to ▪ receive the masonry reference tool, and ▪ guide the masonry reference tool relative to the masonry profile clamp after receiving the masonry reference tool; a first securing body arranged at the first side portion of the elongated body, wherein the first securing body is configured to clamp the masonry profile clamp onto the masonry profile between the second side portion and the first securing body; a second securing body arranged at the reference tool guide, the second securing body having o an unlocking state, in which the masonry reference tool is moveable through the reference tool guide relative to the masonry profile clamp, and o a locking state, in which the masonry reference tool is fixable to the masonry profile clamp.

[0008] A masonry profile clamp is configured to clamp onto a masonry profile extending within a clamping width of the masonry profile clamp. The masonry profile is set up at the beginning of the masonry process. The masonry profile for example comprises a vertical post, which is vertically positioned in the ground or foundation to serve as the main support for the profile. Generally, props, struts or braces are attached to the masonry profile to provide additional support and stability. Optionally, multiple masonry profiles are connected by horizontal crossbars, creating a rectangular or square frame. These crossbars form the top and bottom edges of the masonry profile. Masonry profiles are commonly constructed from durable materials such as wood, aluminium, steel, or reinforced plastic. These materials provide strength and stability while remaining lightweight for ease of handling. The masonry profile may have a square cross-section. The height of the masonry profile may range between 1.5 to 3 meters. The diameter or width of the masonry profile is commonly around 6-10 cm, e.g. 9 cm.

[0009] The masonry profile clamp comprises an elongated body. The elongated body may have a rectangular shaped portion. The elongated body extends in a longitudinal direction between a first end and a second end. The first end has a first side portion extending in a transverse direction transverse to the longitudinal direction. The second end has a second side portion extending in the transverse direction transverse to the longitudinal direction. The second side portion is parallel to the first side portion. The elongated body for example has a U-shaped form. The distance between the first side portion and the second side portion defines the clamping width of the masonry profile clamp.

[0010] The elongated body further comprises a reference tool guide. The reference tool guide is arranged between the first end and the second end. The reference tool guide is configured to receive a masonry reference tool, and to guide the masonry reference tool relative to the masonry profile clamp after receiving the masonry reference tool. The masonry reference tool is for example a reference strip, e.g. a flexible reference strip configured to be rolled up. The masonry reference tool may include one or more scale markings arranged in a longitudinal direction of the masonry reference tool, for example as rows. In an embodiment, the masonry reference tool includes four scale markings: a first, second, third and fourth scale marking. The first scale marking may be a measurement indicator according to the metric system, i.e., scale marking in centimetres. A second scale marking for example displays a first module size and a first zone corresponding to a first joint thickness. The first module size is a measurement of a brick having a standard dimension of, for example, 50 mm. The first joint thickness can be, for instance, 10 mm. A third scale marking displays the first module size with a second zone corresponding to a second joint thickness, for example 12 mm. A fourth scale marking displays the first module size with a third zone corresponding to a third joint thickness, for example 14 mm. The first module size is bordered on both sides by the zone corresponding to the desired joint thickness. This way, the masonry reference tool is easily applicable in masonry using bricks with a module size of 50 mm. The scale markings, such as the module size and desired joint thickness, indicate where a masonry cord should be placed or to how high the masonry cord has to be moved for laying a subsequent layer of bricks.

[0011] The masonry profile clamp further comprises a first securing body arranged at the first side portion of the elongated body. The first securing body is configured to clamp the masonry profile clamp onto the masonry profile between the second side portion and the first securing body. Alternatively, the first securing body is arranged at the second portion of the elongated body, wherein the first securing body is configured to clamp the masonry profile clamp onto the masonry profile between the first side portion and the first securing body. Additionally, the masonry profile clamp comprises an additional first securing body, wherein the additional first securing body is arranged at the first side portion or at the second side portion of the elongated body, wherein the first securing body and the additional first securing body are configured to clamp the masonry profile clamp onto the masonry profile between the first securing body and the additional first securing body.

[0012] The masonry profile clamp further comprises a second securing body arranged at the reference tool guide. Preferably, the second securing body is arranged at or near the centre of the reference tool guide. The second securing body has an unlocking state and a locking state. In the unlocking state, the masonry reference tool is moveable through the reference tool guide relative to the masonry profile clamp. In the locking state, the masonry reference tool is fixable to the masonry profile clamp. The second securing body has to be in the unlocking state such that the reference tool guide is able to receive the masonry reference tool. When the reference tool guide has received the masonry reference tool, e.g. by manually putting the masonry reference tool into the reference tool guide, a user can move the masonry reference tool through the reference tool guide relative to the masonry profile clamp being clamped onto the masonry profile. When the desired position of the masonry reference tool with respect to the masonry profile is reached, the state of the second securing body can be shifted from the unlocking state to the locking state, whereby the masonry reference tool is fixated to the masonry profile clamp.

[0013] The masonry reference clamp according to the invention being clamped to the masonry profile allows for an easy and time-efficient placing and / or adjustment of the masonry reference tool relative to the masonry profile. A user is able to fixate the masonry reference tool to a desired position relative to the masonry profile without the need of additional measuring equipment, such as (folding) rulers. Furthermore, adjusting the height of the masonry reference tool during construction is easily achieved by utilizing the second securing body to move and fixate the masonry reference tool at the desired height. For example, it is not needed to reattach the masonry profile clamp onto the masonry profile.

[0014] In an embodiment, the elongated body further comprises at least one opening such that one or more scale markings of the masonry reference tool are visible when the masonry reference tool is moved through the reference tool guide or is fixated to the masonry profile clamp. Preferably, the at least one opening is provided adjacent to the first side portion and / or the second side portion. Additionally or alternatively, the at least one opening is provided in the reference tool guide. During the masonry process, the at least one opening ensures that the one or more scale markings of the masonry reference tool are visible for a user when the masonry reference tool is moved through the reference tool guide or is fixated to the masonry profile clamp. The at least one opening makes it easier to read the one or more scale markings, such as the desired joint thickness, and / or to attach a masonry cord to the masonry profile or masonry profile clamp.

[0015] In an embodiment, the reference tool guide extends in the longitudinal direction parallel to the elongated body between the first end and the second end. The reference tool guide for example partially extends over a length of the elongated body, the length being defined in the longitudinal direction from the first side portion to the second side portion. The reference tool guide for example extends from the first side portion to adjacent the centre of the elongated body.

[0016] Additionally, the reference tool guide is configured to guide the masonry reference tool guide relative to the masonry profile clamp in a vertical direction, which is transverse to both the longitudinal direction and transverse direction, after receiving the masonry reference tool. This vertical guidance capability ensures precise alignment of the masonry reference tool during use, for example when the masonry profile clamp is attached to a vertical masonry profile.

[0017] In an embodiment, the reference tool guide comprises a guiding slit having a first guide slit end and a second guide slit end, the first guide slit end being adjacent to the first end and / or the second guide slit end being adjacent to the second end. The guiding slit is configured to receive the masonry reference tool and guide the masonry reference tool relative to the masonry profile clamp after receiving the masonry reference tool. At least one guide slit end is positioned adjacent to the respective end of the elongated body, for example the first guide slit end is arranged at the first end of the elongated body. This embodiment advantageously brings the masonry reference tool close to the side of the masonry profile when the masonry profile clamp is clamped onto the masonry profile. As a result, a user can directly align a mason's cord along the side of the masonry profile using the masonry reference tool, which facilitates the alignment process. The guiding slit for example includes the at least one opening such that one or more scale markings of the masonry reference tool are visible when the masonry reference tool is moved through the reference tool guide or is fixated to the masonry profile clamp.

[0018] In an embodiment, the first securing body is a screw, for example a thumb screw, or a bolt, for example a bolt having one or more predetermined breaking points. The one or more predetermined breaking points result in a weakened portion along the length of the bolt. This offers the advantage that when for example a user collides with the bolt, the bolt breaks at the weakened portion, while the masonry profile clamp itself remains intact and securely clamped onto the masonry profile. The broken bolt can be easily replaced with a new one without requiring replacement of the entire masonry profile clamp. Alternatively, the bolt can proactively be broken at the weakened portion to prevent potential collisions with the protruding bolt.

[0019] In an embodiment, the masonry profile clamp further comprises a moveable side portion extending in the transverse direction transverse to the elongated body, the moveable side portion being parallel to the first and second side portion, wherein the moveable side portion is connected to the first securing body, wherein the first securing body is configured to move the moveable side portion along the elongated body between the first end and the second end to adjust the clamping width of the masonry profile clamp, and clamp the masonry profile clamp onto the masonry profile between the second side portion and the moveable side portion. The first securing body, e.g. being a screw, may be rotated manually or by using for example a screwdriver, electric screwdriver, or another appropriate tool. By rotating the first securing body, the moveable side portion being connected to the first securing body is moved along the elongated body between the first end and the second end. In this embodiment, the clamping width of the masonry profile clamp is defined by the distance between the moveable side portion and the second side portion. The clamping width can be adjusted by moving the moveable side portion to a desired position on the elongated body, which position is e.g. based on the width of the masonry profile. When the masonry profile clamp is clamped onto the masonry profile, the masonry profile extends between the second side portion and the movable side portion.

[0020] Alternatively, the first side portion and / or the second side portion are moveable along the elongated body to adjust the clamping width of the masonry profile clamp. The first securing body is connected to the first side portion, and optionally an additional first securing body is connected to the second side portion. In this alternative embodiment, the clamping width of the masonry profile clamp is defined by the distance between the first side portion and the second side portion. The clamping width can be adjusted by moving the first side portion and / or second side portion to desired position(s) on the elongated body, which position(s) are e.g. based on the width of the masonry profile. When the masonry profile clamp is clamped onto the masonry profile, the masonry profile extends between the first side portion and the second side portion.

[0021] In an embodiment, the second securing body comprises a rotational element and an engaging element arranged at the reference tool guide, the rotational element comprising a top structure, a bottom structure and a rotation pin connecting the top structure with the bottom structure, the bottom structure facing the masonry reference tool when being moved through the reference tool guide, wherein the rotation pin is configured to rotatably engage the engaging element between a first rotational position, wherein the second securing body is in the unlocking state and the bottom structure is arranged at an offset from the masonry reference tool, and a second rotational position, wherein the second securing body is in the locking state and the bottom structure contacts the masonry reference tool. The rotational element comprises a top structure, a bottom structure and a rotation pin. The top structure extends outwardly transverse to the elongated body. The reference tool guide is configured to accommodate the bottom structure. The bottom structure faces the masonry reference tool when the masonry reference tool is moved through the reference tool guide. The rotation pin connects the top structure with the bottom structure. The rotation pin for example comprises at least one protrusion between the bottom structure and the top structure. The at least one protrusion extend transverse to the rotation axis of the rotational pin. The engaging element is arranged at the reference tool guide. The engaging element may comprise a first notch, a second notch and, optionally, a slant structure extending between the first notch and the second notch. The first notch is for example arranged in the same longitudinal plane of the elongated body. The second notch is for example arranged at an offset transverse from the longitudinal plane of the elongated body in the transverse direction, e.g. at an offset relative to the first notch in the transverse direction. As a result, there is a distance between the first notch and the second notch in the transverse direction transverse to the longitudinal direction.

[0022] The rotational pin is configured to rotatably engage the engaging element between a first rotational position and a second rotational position. In the first rotational position, the second notch engages the protrusion of the rotational pin. Thereby, the bottom structure is arranged at an offset from the masonry reference tool. As a result, the second securing body is in the unlocking state, such that the masonry reference tool is moveable through the reference tool guide relative to the masonry profile clamp. When rotating the rotational pin along the rotation axis, e.g. by turning the top structure along the rotation axis, the rotational element is rotated from the first rotational position to second rotational position. For example, the top structure comprises a handle configured to rotate the rotational element between the first rotational position and the second rotational position. During the rotation, the protrusion is guided along the slant structure from the second notch to the first notch. In the second rotational position, the first notch engages the protrusion of the rotational pin. Thereby, the bottom structure contacts the masonry reference tool. Consequently, the second securing body in the locking state, such that the masonry reference tool is fixated to the masonry profile clamp. The bottom structure may be configured with an elongated shape, optimizing both functional performance and spatial efficiency. The elongated shape increases the contact surface area between the bottom structure and the masonry reference tool, thereby allowing the clamping force exerted by the second securing body to be distributed more evenly. This even distribution enhances the stability and secure positioning of the masonry reference tool, reducing the risk of localized pressure points that could cause damage of the masonry reference tool or slippage. Additionally, the elongated shape contributes to a compact and streamlined structural design, while minimizing material usage.

[0023] In an alternative embodiment, the second securing body is a screw, for example a thumb screw, a bolt or a spring system.

[0024] In an embodiment, the clamping width of the masonry profile clamp ranges between 50-100 mm, preferably between 55-95 mm, more preferably between 60-90 mm.

[0025] In an embodiment, the elongated body and / or the reference tool guide are made of a transparent material, for example polycarbonate. The masonry profile clamp is for example made of polyamide or polypropylene and fiberglass. By incorporating fiberglass into polypropylene, the mechanical properties such as tensile strength and compressive strength of the thermoplastic polypropylene are significantly enhanced. Furthermore, fiberglass-reinforced polypropylene is cost-effective, durable and easily recyclable.

[0026] According to another aspect of the invention, the invention further pertains to a method for fixating a masonry reference tool using a masonry profile clamp. For example, the masonry profile clamp is a masonry profile clamp according to the invention. However, the method according to the invention is not limited thereto. In the method according to the invention, any of the embodiments of the masonry profile clamp as described above can be used. Also features and components described with regard to methods can be applied in the masonry profile clamp according to the invention. Features, components and definitions used with regard to the method according to the invention have the same meaning as explained with respect to the masonry profile clamp according to the invention, unless explicitly stated otherwise.

[0027] The object of the invention is further achieved with a method for fixating a masonry reference tool using a masonry profile clamp, the method comprising the steps of: attaching the masonry profile clamp to a masonry profile to clamp the masonry profile clamp onto the masonry profile within a clamping width of the masonry profile clamp using a first securing body, the masonry profile clamp comprising o an elongated body extending in a longitudinal direction between ▪ a first end having a first side portion extending in a transverse direction transverse to the longitudinal direction, and ▪ a second end having a second side portion extending in the transverse direction transverse to the longitudinal direction, the second side portion being parallel to the first side portion; the elongated body comprising a reference tool guide arranged between the first end and the second end; o the first securing body arranged at the first side portion of the elongated body; o a second securing body arranged at the reference tool guide; moving the masonry reference tool relative to the masonry profile clamp through the reference tool guide; determining a height reference with respect to the masonry profile; fixating the masonry reference tool to the masonry profile clamp using the second securing body based on the determined height reference.

[0028] First, the masonry profile clamp is attached to the masonry profile to clamp the masonry profile clamp onto the masonry profile. The first securing body is used to clamp the masonry profile clamp onto the masonry profile. When the second securing body of the masonry profile clamp is in the unlocking state, the masonry reference tool is moved relative to the masonry profile clamp through the reference tool guide. Additionally, a height reference is determined with respect to the masonry profile. The height reference is determined relative to a reference point, for example a ground surface or foundation, e.g. by using a laser device. By using the laser device together with a scale marking of the masonry reference tool, the masonry reference tool can be arranged at the desired height. Based on the determined height reference, the masonry reference tool is fixated to the masonry profile clamp using the second securing body. So, the second securing body is shifted from the unlocking state to the locking state.

[0029] Via the one or more scale markings on the masonry reference tool, a user is able to start laying horizontal layers of bricks to build a construction, e.g. a wall, for example between two masonry profiles. Optionally, a masonry cord is used extending between the masonry profiles. The masonry cord is for example attached to the masonry profiles.

[0030] In an embodiment, the method further comprises the step of providing at least one opening in the elongated body such that one or more scale markings of the masonry reference tool are visible when the masonry reference tool is fixated to the masonry profile clamp. Preferably, the at least one opening is provided adjacent to the first side portion and / or the second side portion. Additionally or alternatively, the at least one opening is provided in the reference tool guide.

[0031] In an embodiment, the method further comprises the step of clamping multiple masonry profile clamps onto the masonry profile, wherein adjacent masonry profile clamps are vertically spaced apart. Adjacent masonry profile clamps are vertically spaced apart along the masonry profile. For example, the distance between adjacent masonry profile clamps is between 30-50 cm, e.g. 40 cm.

[0032] In an embodiment, the method further comprises the step of unlocking the second securing body, after the fixating step, allowing the masonry reference tool to move relative to the masonry profile clamp through the reference tool guide. When a particular height of the construction is reached, the user can relatively easy adjust the height of the masonry reference tool relative to the ground surface utilizing the second securing body to move and fixate the masonry reference tool at a new height relative to the reference point. Thereby, it is not needed to reattach the masonry profile clamp on the masonry profile.

[0033] According to another aspect of the invention, the invention further pertains to a system comprising one or more masonry profile clamps according to the invention, and a masonry reference tool. The masonry reference tool may include one or more scale markings arranged in a longitudinal direction of the masonry reference tool. The masonry reference tool is for example a reference strip, e.g. a flexible reference strip, configured to be rolled up. The one or more scale markings may display a module size and / or a desired joint thickness.

[0034] The invention will be described in more detail below with reference to figures, in which in a non-limiting manner exemplary one or more embodiments of the invention will be shown. The same reference numerals in different figures indicate the same characteristics in different figures.

[0035] In the figures: Fig. 1: Schematically shows a perspective view (Fig. 1(a)) and side view (Fig. 1(b)) of a masonry profile clamp according to the invention for fixating a masonry reference tool, wherein a second securing body is an unlocking state; Fig. 2: Schematically shows a perspective view (Fig. 2(a)) and side view (Fig. 2(b)) of the masonry profile clamp according to Fig. 1, wherein the second securing body is an locking state; Fig. 3: Schematically shows an embodiment wherein multiple masonry profile clamps according to the invention are clamped onto a masonry profile (Fig. 3(a)), wherein a masonry reference tool (Fig. 3(b)) is fixated for each masonry profile.

[0036] Figs. 1-2 schematically shows a perspective view (Fig. 1(a), Fig. 2(a)) and side view (Fig. 1(b), Fig. 2(b)) of a masonry profile clamp 100 according to the invention for fixating a masonry reference tool (see Fig. 3), wherein a second securing body is an unlocking state (Fig. 1) and in a locking state (Fig. 2). For sake of clarity, a cartesian coordinate system is shown.

[0037] The masonry profile clamp 100 comprises an elongated body 101 extending in a longitudinal direction, i.e. the X-direction. The elongated body 101 has a rectangular shaped portion. The elongated body 101 comprises a first end 101a having a first side portion 102 extending in a transverse direction, i.e. the Y-direction, transverse to the longitudinal direction. The elongated body 101 further comprises a second end 101b having a second side portion 103 extending in the transverse direction, i.e. the Y-direction, transverse to the longitudinal direction. The second side portion 102b is parallel to the first side portion 102a. The elongated body 101 has U-shaped form (see for example in Fig. 1(b) or Fig. 2(b)).

[0038] The elongated body 101 further comprises a reference tool guide 104. The reference tool guide 104 comprises a guiding slit 105 having a first guide slit end 105a and a second guide slit end 105b. The first guide slit end 105a is adjacent near the centre of the elongated body 101. The second guide slit end 105b is adjacent to the second end 101b. This advantageously brings the masonry reference tool close to a side of the masonry profile (not shown) when the masonry profile clamp 100 is clamped onto the masonry profile. As a result, a user can directly align a mason's cord (not shown) along the side of the masonry profile using the masonry reference tool, which facilitates the alignment process. The guiding slit 105 is configured to receive the masonry reference tool and guide the masonry reference tool relative to the masonry profile clamp 100 in a vertical direction (Z-direction), which is transverse to both the longitudinal direction (X-direction) and the transverse direction (Y-direction), after receiving the masonry reference tool.

[0039] The masonry profile clamp 100 further comprises a first securing body 106 arranged at the first side portion 101a of the elongated body 101. The first securing body 106 is configured to clamp the masonry profile clamp 100 onto the masonry profile between the second side portion 101b and the first securing body 106. The first securing body 106 can be rotated along a clamping axis CA manually or by using for example a screwdriver, electric screwdriver, or another appropriate tool. By rotating the first securing body 106 the clamping width CW of the masonry profile clamp 100 is adjusted. The maximal clamping width CWMAX is defined by the distance between the first side portion 101a and the second side portion. In this embodiment, the distance between an end 106a of the first securing body 106 and the second side portion 101b defines the clamping width CW of the masonry profile clamp 101. The clamping width CW of the masonry profile clamp 100 ranges between 50-100 mm, preferably between 55-95 mm, more preferably between 60-90 mm.

[0040] As shown in Figs. 1-2, the first securing body 106 is a bolt having multiple predetermined breaking points 106b. The predetermined breaking points 106b result in a weakened portion along the length of the bolt. This offers the advantage that when for example a user collides with the bolt, the bolt breaks at the weakened portion, while the masonry profile clamp 100 itself remains intact and securely clamped onto the masonry profile. The broken bolt can be easily replaced with a new one without requiring replacement of the entire masonry profile clamp 100. Alternatively, the bolt can proactively be broken at the weakened portion to prevent potential collisions with the protruding bolt.

[0041] The masonry profile clamp 100 further comprises the second securing body 107 arranged at the reference tool guide 104. The second securing body 107 has an unlocking state (see Fig. 1) and a locking state (see Fig. 2). In the unlocking state, the masonry reference tool is moveable through the reference tool guide 104 relative to the masonry profile clamp 100. In the locking state, the masonry reference tool is fixable to the masonry profile clamp 100. The second securing body 107 has to be in the unlocking state such that the reference tool guide 104 is able to receive the masonry reference tool. When the reference tool guide 104 has received the masonry reference tool, e.g. by manually putting the masonry reference tool into the reference tool guide 104, a user can move the masonry reference tool through the reference tool guide 104 in the vertical direction relative to the masonry profile clamp 100 while being clamped onto the masonry profile. When the desired position of the masonry reference tool with respect to the masonry profile is reached, the state of the second securing body 107 can be shifted from the unlocking state to the locking state, whereby the masonry reference tool is fixated to the masonry profile clamp 100.

[0042] In the shown example of Figs. 1-2, the second securing body 107 comprises a rotational element 108 and an engaging element 109 arranged at the reference tool guide 104. The rotational element 108 comprises a top structure 108a, a bottom structure 108b and a rotation pin 108c. The top structure 108a is a handle. The bottom structure 108b has an elongated shape. The rotation pin 108c is arranged transverse to the elongated body 101, i.e. in the Y-direction. The reference tool guide 104 accommodates the bottom structure 108b. The bottom structure 108b faces the masonry reference tool when the masonry reference tool is moved through the reference tool guide 104. The rotation pin 108c connects the top structure 108a with the bottom structure 108b. The rotation pin 108c comprises two protrusions 108d. The two protrusions 108d are arranged opposite to each other on the rotation pin 108c. The two protrusions 108d extend transverse to a rotation axis RA of the rotational pin 108c. In Fig. 1, the protrusions 108d are directed in the Z-direction.

[0043] The engaging element 109 is arranged at the reference tool guide 104. The engaging element 109 comprises a first notch 109a, a second notch 109b and a slant structure 109c extending between the first notch 109a and the second notch 109b. The second notch 109b is arranged at an offset relative to the first notch 109a in the transverse direction, i.e. in the Y-direction, transverse to the elongated body 101.

[0044] The rotational pin 108c is configured to rotatably engage the engaging element 109 between a first rotational position (see Fig. 1) and a second rotational position (see Fig. 2). In the first rotational position, the second notch 109b engages the protrusion 108d of the rotational pin 108c. Thereby, the bottom structure 108b is arranged at an offset from the masonry reference tool when the masonry reference tool is moved through the reference tool guide 104. As a result, the second securing body 106 is in the unlocking state, such that the masonry reference tool is moveable through the reference tool guide 104 relative to the masonry profile clamp 100. When rotating the rotational pin 108c clockwise 90 degrees along the rotation axis RA, e.g. by manually turning the top structure 108c along the rotation axis, the rotational element 108 is rotated from the first rotational position (Fig. 1) to the second rotational position (Fig. 2). During the rotation, the protrusion 108d is guided along the slant structure 109c from the second notch 109b to the first notch 109a. In the second rotational position, the first notch 109a engages the protrusion 108d of the rotational pin 108c. Thereby, the bottom structure 108 contacts the masonry reference tool when the masonry reference tool is moved through the reference tool guide 104. Consequently, the second securing body 107 in the locking state, such that the masonry reference tool is fixated to the masonry profile clamp 100. Further, an opening 111 is provided in the reference tool guide 104. The opening 111 of the reference tool guide 104 has approximately the same elongated shape as the bottom structure 108b. In the first rotational position (Fig. 1), the opening 111 of the reference tool guide 104 allows the bottom structure 108b to pass through it so that the rotational element 108 can be removed or replaced, for example, when the rotational element 108 is damaged or broken.

[0045] The elongated body 101 further comprises three openings 110. The three openings 110 are provided adjacent to the second side portion 103. The three openings 110 ensure that the one or more scale markings of the masonry reference tool are visible for a user when the masonry reference tool is moved through the reference tool guide 104 or is fixated to the masonry profile clamp 100. The three openings 110 make it easier to read the one or more scale markings, such as the desired joint thickness, and / or to attach a masonry cord to the masonry profile or masonry profile clamp 100. Additionally or alternatively, the opening 111 of the reference tool guide 104 allows visualisation of one or more scale markings of the masonry reference tool when the masonry reference tool is fixated to the masonry profile clamp 100 (Fig. 2).

[0046] The masonry profile clamp 100 being clamped onto the masonry profile allows for an easy and time-efficient placing and / or adjustment of the masonry reference tool relative to the masonry profile. A user is able to fixate the masonry reference tool to a desired position relative to the masonry profile without the need of additional measuring equipment, such as (folding) rulers. Furthermore, adjusting the height of the masonry reference tool during construction is easily achieved by utilizing the second securing body 107 to move and fixate the masonry reference tool at the desired height. For example, it is not needed to reattach the masonry profile clamp 100 on the masonry profile.

[0047] In Fig. 3, an embodiment is shown wherein multiple masonry profile clamps 300 according to the invention are clamped onto a masonry profiles 300, wherein a masonry reference tool 302 is fixated for each masonry profile 301. The masonry reference tool 302 (see Fig. 3(b)) is for example a reference strip, e.g. a flexible reference strip, configured to be rolled up. The masonry reference tool 302 include three scale markings 303,304,305 arranged in a longitudinal direction of the masonry reference tool: a first scale marking 303, a second scale marking 304 and a third scale marking 305. The first scale marking 303 is a measurement indicator according to the metric system, i.e., scale marking in centimetres. The first scale marking 303 can serve as a reference point for adjusting one or more masonry profile clamps 300 on different masonry profiles to the same height. The second scale marking 304 displays a first module size 304a and a first zone 304b corresponding to a first joint thickness. In the shown example, the first module size 304a is a measurement of a brick having a standard dimension of 50 mm. The first joint thickness is 15 mm. The third scale marking 305 displays the first module size 304a with a second zone 305b corresponding to a second joint thickness, being 3 mm. The first module size 304a is bordered on both sides by the zone 304b,305b corresponding to the desired joint thickness. This way, the masonry reference tool 302 is easily applicable in masonry using bricks with a module size of 50 mm. The first scale marking 304 and the second scale marking 305 are applied to both sides of the masonry reference tool 302. The scale markings 303,304,305, such as the module size and desired joint thickness, indicate where a masonry cord 306 should be placed or to how high the masonry cord 306 has to be moved for laying a subsequent layer of bricks 307.

[0048] First, the multiple masonry profile clamps 300 are attached to the masonry profile 301 to clamp the multiple masonry profile clamps 300 onto the masonry profile 301. The first securing body is used to clamp each masonry profile clamp 300 onto the respective masonry profile 301. Adjacent masonry profile clamps 300 are vertically spaced apart along the respective masonry profile 301. For example, the distance between adjacent masonry profile clamps 300 is between 30-50 cm, e.g. 40 cm.

[0049] Subsequently, when the second securing body of each masonry profile clamp 300 is in the unlocking state, the masonry reference tool 302 is moved relative to the masonry profile clamps 300 through the reference tool guide of each masonry profile clamp 300. During the process, a height reference is determined with respect to the respective masonry profile 301. The height reference is determined relative to a reference point, e.g. the ground surface 308, via a laser device 309. By using the laser device 309 together with the first scale marking 303 of the masonry reference tool 302, the masonry reference tool 302 can be arranged at the desired height. Based on the determined height reference, the masonry reference tool 302 is fixated to the masonry profile clamp 300 using the second securing body. So, the second securing body of each masonry profile clamp 300 is shifted from the unlocking state to the locking state.

[0050] Via the scale markings 303,304,305 on the masonry reference tool 302, a user is able to start laying horizontal layers of bricks 307 to build a construction, e.g. a wall, between two adjacent masonry profiles 301 (in Fig. 3(a) only one masonry profile is shown). When a particular height of the construction is reached, the user can relatively easy adjust the height of each masonry reference tool 302 utilizing the second securing body of each masonry profile clamp 300 to move and fixate the masonry reference tool 302 at a new height relative to the ground surface 308. Thereby, it is not needed to reattach the masonry profile clamp 300 on the masonry profile 301.
