A connection device in particular for building construction, has an upright, a beam and a pair of first plates, which are flat and vertical, are fixed with respect to the upright, project horizontally from the upright and are parallel to each other; the device also has a pair of second plates, which are fastened to one end of the beam, are placed on the outer side faces of such end are flat and vertical, coplanar respectively to the first plates and rest on the first plates solely at an inclined plane, which causes a forcing of the end of the beam horizontally against the upright in response to a forcing of the second plates downwards along such inclined plane.

A connecting assembly for connecting two components in construction, having a first component with an anchor element, which has a connecting portion and a second component with at least one housing part, which has a conical or wedge-shaped inner surface, fixed therein or thereon. A clamping part having a conical or wedge-shaped outer surface is in the housing part, which clamping part, when connected to the anchor element, clamps the connecting portion of the anchor element so that, when a tensile force acts on the connecting portion, the outer surface of the clamping part is pulled against the inner surface of the housing part such that the clamping force acting on the connecting portion increases. When not connected to the anchor element, the clamping part has a range of motion with respect to the inner surface of the housing part; however, the housing part is spatially delimited in all directions.

A wooden structural joint is provided, including a wooden rectangular base member comprising, at one end, a removed center element, a plurality of removed center edge elements, and four intact corner elements, where the removed center element and the plurality of removed center edge elements are formed from vertical and horizontal cuts into the one end of the wooden rectangular base member, a plurality of horizontal members, each horizontal member having a height and further having a tab cut therein at one edge of the horizontal member, the tab cut at a percentage of the height such that all horizontal members fit securely together when assembled within the wooden rectangular base member, and a wooden rectangular top member having one end cut similar to the wooden rectangular base member.

A modular building system and kit therefor includes a joist assembly, at least one supported member, and at least one connector that includes a retaining portion for retaining the supported member and a retained portion for engaging the joist assembly. The joist assembly may include a pair of oppositely facing beam members and a joist supporting member being partially pinched between the beam members and defining a gap therebetween. The connector may be received within the gap. The supported member may be a supported stud or a blocking member. The connector may be a double-ended connector or a hanger connector. A modular wall panel or ceiling panel of the system includes a first member for retaining a first insulation panel, a second member for retaining a second insulation panel and a thermal bridge breaking member forming a connection between the first and second members.

A beam has an upper face, a lower face, side faces, and an end face. The end face has a rectangular configuration and is vertically disposed. The end face has a slot vertically disposed and parallel with, and equally spaced from, the side faces. Beam holes extend through the beam on opposite sides of the slot. A post has a front face, a parallel rear face, and parallel side faces. A connector has a first section and a second section. Beam apertures are formed in the first section. The first section is positioned in the slot with the beam apertures aligned with the beam holes. The second section is attached to the post. Dowels extend through the beam holes and the beam apertures thereby coupling the beam to the post. The system also includes tools for accurately cutting and drilling components, wood and otherwise, to be coupled.

The invention relates to a modular structural system obtained from the combination, in sliding engagement form, of generically elongated elements A, B, C, D having sections whose perimeter is provided with protrusions and recesses which, in the spatial development of the elements A, B, C, D, form sliding channels or tracks for mutual sliding of the elements which form the structural system. The structural system may also be provided with node elements C shaped so as to have two parallel opposite surfaces, one of which is provided with sliding channels or tracks for mutual male/female engagement in corresponding sliding channels or tracks and the other surface of which is provided with a permanent or releasable connection with other elements A, B, C, D at a connection angle of 0<a<180 with respect to said opposite surfaces. The structural system may also be provided with nodes A, B, C instead of the node elements C.

A wooden structure building self-constructing method includes the operations of: (a) assembling a first kit by disposing N (N is a natural number) second modules of a second shape each including one or more second fitting portions cut out to a second length (d2) in the direction of the center thereof between two first modules of a first shape each including one or more first fitting portions cut out to a first length (d1) in the direction of the center thereof; and (b) assembling a second kit by disposing N fourth modules of a fourth shape each including one or more fourth fitting portions cut out to a fourth length (d4) in the direction of the center thereof between two third modules of a third shape each including one or more third fitting portions cut out to a third length (d3) in the direction of the center thereof.

According to an example embodiment of the present disclosure, there is provided a self-building kit system including a first kit. The first kit includes: first modules of a first shape having two modules disposed opposite each other, and each including one or more first fitting portions cut out to a first length (d1) in the direction of the center thereof; and second modules of a second shape having N (N is a natural number) modules disposed between the two first modules, and each including one or more second fitting portions cut out to a second length (d2) in the direction of the center thereof. The second length (d2) is equal to or shorter than the first length (d1).

A connector arrangement for connecting a timber column to a base includes a releasable split nut for releasably gripping a rod, where the releasable split nut is disposed on the timber column, and a quickly mountable nut, where the quickly mountable nut is disposed on the base. The quickly mountable nut allows insertion of the rod into the quickly mountable nut and inhibits withdrawal of the rod from the quickly mountable nut.
