A coupling device for the modular construction of structures or objects includes a main body having at least one through-opening or at least one recess and being adapted to be coupled to at least one component of a structure or object. The at least one through-opening or the at least one recess is designed to interact with a coupling means for coupling the at least one component to the main body. The main body is formed as a corner element or edge element of a module of the structure or object.

An interconnect system for coupling first and second frame members includes female and male interconnect members. The female interconnect is secured to the first frame member and has defined therein a receptacle. The male interconnect member is secured to the second frame member and defines a protrusion configured for selective axial insertion into, and mating engagement with, the receptacle. The receptacle extends axially between a receptacle opening through which the protrusion is axially received and a receptacle rear wall at which the receptacle terminates. The protrusion terminates at a protrusion tip. The receptacle and protrusion are furthermore configured such that at least one of (a) the receptacle and the protrusion are complementarily keyed in order to prevent relative rotational displacement of the male and female interconnect members when they are in mutual mating engagement, and (b) the protrusion tip is magnetically attracted toward the receptacle rear wall.

A joint comprising: a tenon, a mortise for receiving the tenon, an aperture formed in one of the tenon and an interior wall of the mortise and a pin which extends from the other of the tenon and the interior wall of the mortise; wherein the aperture is a hole which is engaged by the pin in use such that the tenon is supported within the aperture, and the tenon is capable of vertical and horizontal motion within the mortise in a plane substantially orthogonal to a longitudinal axis of the pin, the motion being limited by the edges of the aperture.

A modular structure system of detachable members, the system includes a support pillar and various connectors. The support pillar has a main body and a plurality of channel walls outwardly radiating from an outside surface of the main body. The channel walls are disposed lengthwise on the main body from one terminal end of the main body to another terminal end of the main body. The support pillar has a symmetrical cross-sectional shape and each of the channel walls has an expanded distal end forming two lips.

A structural module (1) has a structural frame having structural members forming floor plates (2), wall plates (3), vertical columns (4), braces (7) extending at angles from the columns to the floor plates, and wall studs. The columns and the braces are configured to transfer vertical loads without assistance from the studs. There may be a module-to-module tie (200) affixed to at least one column, and each tie may be affixed to a top surface of a column, to link columns of adjoining modules together in a horizontal plane, and to accommodate misalignment of the modules in the horizontal plane.

A building and construction method include improved workability not causing variation in quality of buildings, by easily joining materials without special processing by forming mortises. A wooden building constructed by fitting horizontal and vertical members includes lower frames, first upper frames, second upper frames, and side joists as horizontal members; and pillars as vertical members, wherein the lower, first upper and second upper frames, and side joists include mortises at part of the lower, first upper and second upper frames, and side joists in longitudinal direction, the first upper frames include an entire length recessed groove in longitudinal direction, the second upper frames include an entire length protrusion in longitudinal direction, the mortises at the lower frames and the first upper frames are through holes, and the pillars include protrusions at both ends, fitting into the mortises at the lower, first upper and second upper frames, and side joists.

A connector includes a first body, a second body, a first fastener, and a second fastener. The first body has a base portion and a protrusion, the protrusion extends away from the base portion along a first direction, and the first body has a first cavity that extends into the protrusion and towards the base portion along the first direction. The second body has a second cavity, which is shaped to receive the protrusion such that rotation of the first body relative to the second body is blocked. The connector may be used to attach structural members, for example during the construction of a modular structure.

A pergola system and bracket is described, which includes a frame having a plurality of vertical spaced apart posts, and horizontal frame members each of which have an internal reinforcing rod passing through at least a portion of the posts/frame members. The internal reinforcing rods are removably secured to a corner connecting element which then connects the posts/frame members to each other making it easier to construct and provides increased stability to the structure upon completion.

A support device for supporting a support member relative to a building structure can include a support body with a support-body opening that is sized to receive the support member. A first finger can extend into alignment with the support-body opening to secure the support member within the support-body opening. A first extension can be configured to move relative to at least part of the support body to move the first finger. Moving the first extension can move the first finger to release the support member to slide within the support-body opening.

The disclosure is directed to an elongated geodesic dome with an arched-tunnel section. In some embodiments including: a first adjustable angle hub connector, the first adjustable angle hub connector being a connector of a first plurality of tubular struts, the first plurality of tubular struts being inserted into the first adjustable angle hub connector; a second adjustable angle hub connector, the second adjustable angle hub connector being a connector of a second plurality of tubular struts, the second plurality of tubular struts being inserted into the second adjustable angle hub connector; a third adjustable angle hub connector, the third adjustable angle hub connector being a connector of a third plurality of tubular struts, the third plurality of tubular struts being inserted into the third adjustable angle hub connector. The adjustable angle hub connectors may be removable for adjusting a length of the arched-tunnel section of the elongated geodesic dome.
