A steel beam and a supporting arrangement for supporting a steel beam at console, the steel beam including a base plate, two web parts, and an end plate at each end of the steel beam. The base plate, the two web parts and the end plates delimit a space. At least one of the ends of the steel beam includes a console supporting slot extending from the at least one end of the steel beam. The console supporting slot is laterally at least partly limited by side plates inside the space of the steel beam, and by the side plates are attached to the end plate and to the base plate.

Building stud (10) for forming a framework for mounting wall panels, comprising a first (12) and a second (14) flange portion and a web portion (16) interconnecting the flange portions. The flange portions comprise a planar, elongated wood fibre member (18, 20), and the web portion comprises a polymer based and/or cellulose fibre based sheet member (22) including a first (24) and a second (26) rectilinear line of weakness, which lines of weakness are parallel and along which the sheet member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position.

Steel installation parts can replace predetermined regions of reinforced concrete components provided for receiving loads, in particular reinforced concrete beams. The steel installation parts can be arranged in a less dense construction without losing bearing capacity, in order to create space for technical installation elements such as lines, cables and channels.

An insulation system and method comprising an insulation layer, an atmospheric regulation layer, a structural support, and an external surface; wherein the atmospheric regulation layer is supported by the structural support, wherein the insulation layer is located between the atmospheric regulation layer and the external surface, wherein the atmospheric regulation layer has a water vapor permeability of not greater than 3 perms at a relative humidity of 25% as measured by ASTM E96 Procedure A Dry Cup, and a water vapor permeability of at least 6 perms at a relative humidity of 75% as measured by ASTM E96 Procedure B Wet Cup, wherein the atmospheric regulation layer has a fire class A rating as measured by ASTM E84, and wherein the continuous atmospheric regulation layer has a ACH50 value of not greater than 10, wherein ACH50 represents an air exchange at 50 Pascals.

A length-adjustable truss stiffener is intended to be used to strengthen truss systems at locations of localized over-stress to reduce the cost from the alternative solution which is to reduce truss spacings. The stiffener consists of two or more sleeves locking around two or more components of the main truss. The sleeves mounted on different truss components are connected to one another with a length-adjustable shank. The stiffener may be used in two-dimensional or three-dimensional trusses. Of a collection of prefabricated trusses necessary to erect a structure, only a subset of one or more trusses are customized with stiffeners according to loading calculations predicting failure of that subset under required loading conditions, while all other trusses are installed in their original prefabricated state.

A structure including a first hollow-section Fibre Reinforced Polymer (FRP) member, and a second hollow-section FRP member arranged at an angle to the first member. A rod extends through the second member. The rod also has a threaded end section extending through or into the first member. The opposed end of the rod is fixed to a further member. A nut secures the threaded end section to the first member, and screwing of the nut and threaded end section together exerts a compressive force on the second member and a tensile force on the rod.

Roof structure, which comprises load bearing roof beams, the longitudinal direction of which roof beams defines the width direction of the roof, roof boards and a first fastening profile and a second fastening profile, which lock to each other in the joint between two roof boards arranged against each other, whereby the first roof board comprises a first fastening profile and the second roof board comprises a second fastening profile, and which fastening profiles are substantially perpendicular to the load bearing roof beams, and which fastening profiles are continuous along the distance between at least two adjacent load bearing roof beams. Furthermore, the invention comprises a roof element suitable to be used in a roof structure.

An insulation system for hanging insulation in a truss is disclosed and includes a first rail configured to be installed on a first truss and a second rail configured to be installed on a second truss spaced apart from the first truss. A first cavity is established between the first rail and the second rail. Further, the first cavity is configured to receive and engage a first insulation batt.
