Structural component for supporting construction panels and a wall comprising the same
A structural component (100) for supporting construction panels is disclosed comprising an I-shaped strip having two parallel strips (P1. P2) and at least one strip (S1) perpendicular to (P1) and (P2). One or both the parallel strips (P1. P2) contain a plurality of substantially flat portions (110) and void portions (120) which alternate in a first direction X along the structural component (100). The flat portions (110) are configured to support the construction panel in plane contact while the void portions (120) are configured to support the construction panels in line contact. The void portions (120) reduce the thermal transmission of the structural component (100) by providing reduced thermal bridges in the transmission path of heat and reducing the contact surface area with adjoining adjacent materials. The structural component (100) described is a drywall stud or a spacer separating two parallelly bonded construction panels.

Prefab Panel, Modular Facade, and Mounting Method Thereof
The modular facade is made of prefab panels comprising a frame structure with horizontal and vertical profiles. The prefab panel includes an outer cladding attached to the frame structure by attaching means. The horizontal and the vertical profiles have a matching shiplap design. A method of mounting the modular facade relies upon the steps of installing brackets to a building structure, for levelling position of the prefab panels, and an anti-tipping element in an upper part of the building structure, so that not very demanding lifting means, such as a small crane, suffices, for suspending subsequent adjacent prefab panels from an upper story.

A mixer and a method for the mixing of a cementitious slurry, configured to calculate the volume of the cementitious slurry in the mixer in order to produce an improved mixing process and/or an improved cementitious product. The mixer comprises a sensor to measure a parameter of the slurry in the mixer that is used to calculate the volume of slurry in the mixer.
A connector (10) to be used for a lightweight construction element (100) is disclosed. The connector (10) is such that it has a first and second pair of angular arms (1a) and (1b) forming angles (Z) and (Z') respectively and meeting at a first and a second point of intersections (P) and (P'). The first and second pair of angular arms (1a) and (1b) are either oriented parallel to each other or are perpendicularly oriented to each other and helps couple a first and a second flange member (130), (140), which again can be oriented parallel or perpendicular to each other. The connector (10) is placed at distance from each other and acts as a replacement for the conventional web in framing structures. The plurality of connectors (10) thus eliminate the need of a full-length web, which results in reduction of metal usage and thus in turn reduced CO2 emission.
