Description

Technical field

[0001] The present invention relates to a method for assembling a wall assembly at a construction site, and a wall assembly for constructing walls assembled according to said method.

Background art

[0002] The ATG Certified Technical Approval ATG 2968, carried out by the UBAtc asbl, relates to prefabricated clay masonry wall panels and their installation on a construction site.

[0003] The method to assemble a load-bearing or non-load-bearing wall assembly at a construction site described therein involves placing a first and second prefabricated wall panel on a levelled base, in particular a floor plate, and mechanically filling the vertical joint between the prefabricated wall panels with injection mortar. The injection mortar, having specific mechanical properties (average compressive strength: 15 N/mm², volumetric mass density: > 2000 kg/m³, bonding strength: >= 0.6 N/mm², flexural strength: >= 4.5 N/mm²), provides stability and strength to the vertical joint and the wall assembly.

[0004] The method known from the ATG Certified Technical Approval ATG 2968, has the disadvantage that mechanically applying injection mortar requires the use of mortar injection machines on the construction site. These machines need to be transported to and from the construction site and need to be carried to the different vertical joints to be filled by the operators doing the filling. Additionally, these machines are unwieldy when the operators use them to fill the joints and need to be cleaned out after use. This makes for a complicated assembly process and slows down the installation of wall assemblies at construction sites (including preparation and clean up).

Disclosure of the invention

[0005] It is an aim of the present invention to overcome at least some of the disadvantages of the state of the art, simplifying and speeding up the installation of wall assemblies for shearing, load-bearing and non-load-bearing walls at a construction site.

[0006] This aim is achieved, according to the invention, with a method of assembling a wall assembly at an assembly location, preferably a construction site, comprising the actions described in the first claim.

[0007] In particular, the invention discloses a method of assembling a wall assembly at an assembly location, preferably a construction site, comprising:

• a wall panel placement of placing a first prefabricated wall panel comprising a first recess at a recess height and a second prefabricated wall panel comprising a second recess at the recess height, next to each other, such that the first recess abuts the second recess, forming a joint recess,
• an anchor insertion of inserting a wall anchor in the joint recess, such that the first end of a wall anchor lies in the first recess and a second, distally removed end of the wall anchor lies in the second recess,
• a recess filling of filling the joint recess with a binding material, preferably an adhesive mortar, more preferably a cement-based mortar.

[0008] This method results in a wall assembly that derives its strength and that of the vertical joint between the prefabricated wall panels from the wall anchors enveloped in the binding material, such as mortar. In the current state of the art, wall assemblies from prefabricated wall panels derive their strength and that of the vertical joint between the prefabricated wall panels from the injection mortar injected in the vertical joint. As a result, the wall assembly assembled with the method according to the present invention displays the necessary strength without requiring the injection of injection mortar in the vertical joint, removing the need to use a mortar injection machine. This has the advantage that the assembly method according to the invention simplifies the assembly or installation of walls at a construction site and speeds it up. It is an added advantage of the method according to the invention that the method reduces the risk of adverse ergonomic effects on the operator during the assembly, because they don't have to handle a unwieldy and heavy mortar injection machine.

[0009] In an embodiment of the present invention the first recess and the second recess in the first prefabricated wall panel, respectively the second prefabricated wall panel, used in the method, have a parallelepipedal shape. The recesses by preference have dimensions (length x depth x height) 12 - 20 cm x 3 - 6 cm x 3 - 6 cm and by further preference 15 cm x 4 cm x 4 cm. The wall anchor used in the method comprises a steel reinforcement bar, for example a rebar, by preference with a diameter of 12 mm and a length of 30 cm, and the binding material used in the method is a cement-based mortar. This has a dual advantage. Firstly, the parallelepipedal shape facilitates the mechanical creation of the recesses. Secondly, the preferred dimensions of the recesses, in combination with the use of a steel rebar of the preferred dimensions as a wall anchor and in combination with the use of cement-based mortar as a binding material, results in an advantageous ratio of the amount of mortar used to the required strength of the anchoring, when the wall anchor is positioned centrally in the joint recess and enveloped by mortar filling the joint recess.

[0010] In an embodiment of the present invention, the wall anchor used in the method is bent, preferably such that the two ends of the wall anchor are positioned under an angle of substantially 90 degrees with respect to each other. This has the advantage that the method can be applied to prefabricated wall panels that are positioned under an angle with respect to each other, preferably to prefabricated wall panels that are positioned perpendicular to each other, in addition to prefabricated wall panels that lie flush with each other.

[0011] In an embodiment of the present invention, the wall anchor used in the method comprises a first and a second spacer for positioning the wall anchor centrally in the joint recess. This has the advantage that the wall anchor can be easily positioned centrally in the joint recess and remains at that central position when filling the recess with binding material. This promotes an advantageous envelopment of the wall anchor by the binding material and, consequently, of an advantageous strength of the anchoring.

[0012] In an embodiment of the present invention, the method further comprises the step of prefilling the joint recess with the binding material. This has a dual advantage. Firstly, the wall anchor can be pushed into a central position after prefilling the joint recess with the binding material and will remain centrally when subsequently filling the joint recess with binding material. Secondly, prefilling the joint recess facilitates advantageously enveloping the wall anchor.

[0013] In an embodiment of the present invention, the method further comprises the step of smoothing out the binding material that fills the joint recess and ensuring that the fill is substantially flush with a face of the respective prefabricated wall panels. This promotes an advantageous envelopment of the wall anchor by the binding material and, consequently, of an advantageous strength of the anchoring. In addition, it facilitates applying finishing when the building of the wall advances to the finishing phase.

[0014] In an embodiment of the present invention, the prefabricated wall panels used in the method each further comprise an upright side and two opposing upright faces, the upright side connecting the two opposing faces. The method further comprises placing the first prefabricated wall panel and the second prefabricated wall panel such that the upright side of the prefabricated wall panel, called the abutting side, abuts the second prefabricated wall panel, forming a vertical joint between the prefabricated wall panels at the abutting side. The method also further comprises filling the vertical joint with a construction foam, preferably an expansive construction foam, more preferably a polyurethane foam, more preferably a fire-proof foam, for example, fire-resistant foam. This has the advantage that when closing the undesired opening in the wall formed by the vertical joint, no injection mortar machine is required. This has the advantage that the assembly method according to the invention simplifies the assembly or installation of walls at a construction site and speeds it up. It is an added advantage of the method according to the invention that it reduces the risk of adverse ergonomic effects on the operator during the assembly, because they don't have to handle an unwieldy and heavy mortar injection machine. An additional benefit when using a fire-proof or fire-resistant foam is that the method can be used in locations where fire-proofing is required, for example on request of the party commissioning the build or because of building regulations.

[0015] In an embodiment of the present invention, the method further comprises building a first and a second prefabricated wall panel in a prefabrication location, wherein the prefabrication location is preferably different from the installation location, applying a first recess at a recess height to the first prefabricated wall panel, applying a second recess at the recess height to the second prefabricated wall panel, and transporting the first and second prefabricated wall panel to the assembly location. This has the advantage that wall panels can be built and recesses applied to the wall panels in a location different from the installation location, with the possibility to do this mechanically under controlled circumstances. This is an opportunity to get wall panels with fewer defects and recesses that are clean and ready for applying subsequent steps in the method.

[0016] The invention also provides for a kit for constructing walls made with the method according to any of the previous claims, comprising a first prefabricated wall panel, a second prefabricated panel, a wall anchor and binding material, characterized in that the first prefabricated wall panel comprises a first recess at a recess height and the second prefabricated wall panel comprises a second recess at the recess height. This kit has the advantage that the required elements necessary to apply the method disclosed by the invention, are jointly made available and the method steps can be executed without having to interrupt the method for getting supplies.

[0017] In an embodiment of the present invention, the kit further comprises a construction foam, preferably an expansive construction foam, more preferably a polyurethane foam. This kit has the advantage that any embodiment of the method in which a construction foam is required, can be executed without having to interrupt the method for getting supplies.

[0018] The invention also provides for a wall assembly for constructing walls made with any method according to the invention, comprising any kit according to the second aspect of the invention, wherein the first prefabricated wall panel abuts the second prefabricated wall panel, characterized in that the first recess abuts the second recess, forming a joint recess, and the wall anchor is positioned in the joint recess, enveloped by binding material, wherein the binding material enveloping the wall anchor fills the joint recess. This has the advantage that the wall assembly derives its strength, and that of the vertical joint between the prefabricated wall panels, from the wall anchors enveloped in binding material, such as mortar. As such, injection mortar and a mortar injection machine as employed in the state of the art are not required during the installation, speeding up the assembly process and reducing the risk of adverse ergonomic effects on the operator during the assembly, because they don't have to handle an unwieldy and heavy mortar injection machine.

[0019] In an embodiment of the present invention, the wall assembly has the following features: the first recess and the second recess have a parallelepipedal shape; the recesses by preference have dimensions (length x depth x height) 12 - 20 cm x 3 - 6 cm x 3 - 6 cm and by further preference 15 cm x 4 cm x 4 cm; the wall anchor comprises a steel reinforcement bar, for example a rebar, by preference with diameter of 12 mm and a length of 30 cm, and is centrally positioned in the joint recess; the binding material is a cement-based mortar. This has the advantage that the connection is constructed in a controlled way, enabling the calculation of how many connections are needed to ensure the necessary tensile, shearing and flexural strength to adhere to the building norms or regulations that are in vigor at the installation location.

[0020] In an embodiment of the present invention, the wall assembly comprises a kit according to the invention that also comprises a construction foam, preferably an expansive construction foam, more preferably a polyurethane foam, more preferably a fire-proof foam, for example, fire-resistant foam. The prefabricated wall panels each further comprise an upright side and two opposing upright faces, the upright side connecting the two opposing upright faces. The upright side of the first prefabricated wall panel, called the abutting side, abuts the second prefabricated wall panel, forming a vertical joint between the prefabricated wall panels at the abutting side, wherein the construction foam substantially fills the vertical joint. This has the advantage that the wall assembly does not have any unwanted openings connecting the spaces on either side of the wall. An additional benefit when using a fire-proof or fire-resistant foam is that the wall assembly can be built in locations where fire-proofing is required, for example on request of the party commissioning the build or because of building regulations.
