A joining element includes at least two joint holes for pin joints as well as a first plane surface and a second plane surface and an inclined surface slanting towards an outer edge of the joining element and arranged at an angle with respect to at least one said plane surface. A method includes joining two wood structures to one another by using the joining element.

An engineered wood structural system including multiple vertical structural elements (10) and multiple horizontal structural elements (20, 120), wherein multiple horizontal structural elements (20, 120) of the same floor level are supported on the same structural node and are rigidly connected to each other through an upper connector (40) at least partially overlapped, and attached, to all the horizontal structural elements (20,120) supported in the structural node to transfer horizontal traction loads between the upper horizontal boards (21) of the connected horizontal structural elements (20, 120).

An engineered wood structural system including multiple vertical structural elements (10) and multiple horizontal structural elements (20, 120) wherein multiple horizontal structural elements (20, 120) of the same floor level are laterally adjacent slabs connected to each other through a perimetral region of the upper horizontal board of one slab attached to a perimetral region of the upper horizontal board of other laterally adjacent slab directly, through complementary staggered steps or through a joint connector, to transfer horizontal loads.

A timber I-beam 701 has a top chord 702 and a bottom chord 704 forming the flanges of I-beam and a series of side by side timber blocks 706 each separated from the next by a gap 722, together forming a uniplanar, intermittent web. Cables and pipes for a building may run transversely through the gaps 722. A method of making the I-beam is described.

A building comprising strong thermal insulation, at least some walls of which consist of panels made of a low-density thermally insulating material, wherein the panels have edge surfaces which are uniformly planar over an entire thickness thereof and are assembled to one another by interleaving boards in joint areas between two adjacent panels, the boards being connected in contact with the panels over an entire length and width of edge surfaces in said joint areas, so that a junction of the boards with the panels prevents by itself alone deformation of the boards in bending transversally to their plane and in twisting and that the panels ensure wind bracing of the walls.

A connector for two components comprises two fittings each with a mounting side, an abutment side opposite the mounting side, and an end face connecting the mounting and abutment sides. At the end faces the fittings may be hooked into one another. The fittings are made of wood or of wood-plastic composite and have one or more generally cylindrical blind holes on their abutment side. The connector comprises, for each blind hole, a molding for removable insertion into the blind hole. The molding has a base surface, a top surface parallel thereto, a substantially generally cylindrical lateral surface connecting these two, and a slanted bore for a mounting screw. The bore penetrates the molding at an acute angle to the base and top surfaces.

A method is for horizontal leveling coupling between a concrete foundation and wooden vertical beams. The method includes (a) perforating n anchor holes in a predetermined position of the concrete foundation (where n is a natural number that is greater than or equal to 2); (b) installing a post-installed anchor in each of the n anchor holes; (c) coupling each of nuts to each thread-shaped anchor head located on an upper portion of the post-installed anchor, wherein the nuts are coupled so that upper surfaces of the nuts coincide with a reference surface X1; (d) preparing wooden vertical beams having lower surfaces in which insertion holes into which the nuts are inserted, are formed; (e) installing the wooden vertical beams by moving the wooden vertical beams in a horizontal direction so that the nuts are inserted into the insertion holes formed in the lower surfaces of the wooden vertical beams, wherein a movement direction of each of the wooden vertical beams is one of two or more movement directions; and (f) filling a space between lower surfaces of the concrete foundation and the nuts with a predetermined member.
