The present disclosure relates to connecting devices and systems for constructing a structure. Specifically, the present disclosure relates to a connector device and system useful for joining structural elements together for constructing a roof on a building. The present disclosure provides embodiments of connectors which are used to secure roof purlins to rafters and/or trusses to enhance the structural integrity of the roof.

A connector assembly, which in one embodiment has an upper connector and in another embodiment has a lower connector. The assembly can have a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly. Also, a system for coupling adjacent modular frame units for forming a modular building and a method for coupling modular frame units for forming a modular building are provided.

A connecting metal (1) includes a tenon pipe (13) having through-holes (132) for fixing the tenon pipe (13) by drift pins or bolts, and a plate (12) joined at an end of the tenon pipe (13) and having through-holes (122) for fixing the plate (12) by drift pins or bolts, the tenon pipe (13) and the plate (12) being joined with each other in a substantially racket-like shape. A pair of slits (131) for receiving the plate is formed at the end of the tenon pipe (13), each of the slits (131) being defined by a first side edge and a second side edge that are bent inwardly. The plate (12) is inserted in the pair of slits (131) and joined with the tenon pipe (13) by welding, with no protrusion of weld reinforcement out of an outer periphery of the tenon pipe (13).

A bracket assembly comprising a first bracket member associated with a first side of a structural element, a second bracket member associated with an opposed second side of the structural element, and wherein the first bracket member, the second bracket member and the structural element are fastened to one another using one or more fastening assemblies.

A system for sealing prefabricated facilities or underground facilities may allow for the sealing and pressurizing of parts or all of an underground facility or enclosed facility via a plurality of sealable doors or prefabricated modules. The system may implement mechanical connections between walls or extensions of individual modules. The system may implement complementary mechanical connections or partially complementary mechanical connections between individual modules and may further include module interior or module exterior sealing layers for rigid layers. The system may implement mechanical connections between individual modules wherein each of the mechanical connections may utilize sealing complementary profiles constructed and arranged to provide for an airtight seal between modules. The system may be used to link surface facilities to underground facilities, tunnels or shafts, or to pressurize sections of tunnels or shafts. The system may be used to stabilize pressurized facilities from back-blast due to evacuation of said tunnels or shafts. The system may be used to construct pressurized surface habitats independent of, or linked to underground tunnels or facilities. The system may further be used to construct space platforms or space stations.

An assembled structure system includes a prefabricated member, a fastener and a locking member. The prefabricated member is provided with at least one cavity, and the fastener is assembled in the at least one cavity. At least one fastener is assembled in each cavity. The cavity includes an upper end surface, a lower end surface, a left end surface and a right end surface. The left end surface or the right end surface includes a vertical surface perpendicularly connected to the upper end surface and an inclined surface connected to the vertical surface. A connection angle between the vertical surface and the outer side of the inclined surface forms an obtuse angle. The inclined surface is connected to the lower end surface. The fastener includes a fixed surface, two side surfaces and a bottom surface. The fixed surface, the two side surfaces and the bottom surface are hingedly connected.

An installation and construction method of a wall panel is provided for installing the wall panel to a pair of wooden columns and a wooden horizontal member, the wooden columns being installed in a standing manner so as to be spaced apart from each other, the wooden horizontal member being installed to the wooden columns. The method includes: forming the wall panel by connecting mutually adjacent end portions of a plurality of surface members in a horizontal direction by a half column extending in a vertical direction, studs being fixed on first plate surfaces of the plurality of surface members; and after installing the wooden horizontal member to the wooden columns and adjusting erection of the wooden columns, fixing edge end portions of the surface members of the wall panel to front surfaces of the wooden columns and a front surface of the wooden horizontal member.

A levelling structure for levelling a structure having supports for secondary support on fixed footings. A coupling mechanism extends between an access point on the structure and the footings. Adjustment of the coupling member from the structure alters the elevation of the structure and supports together towards or away from the footings. By providing the adjustment from the structure itself, the requirement for elevational adjustment beneath the structure is avoided as well as adjustment against the opposition of the load.

A building connection includes a first building element and a second building element arranged at a distance from each other. The first building element is connected to the second building element by at least one connecting device. The connecting device includes a load transfer element arranged in the first building element, and a support box molded into the second building element. The support box includes an inner bottom wall surface and a support box opening facing the first building element. The connecting device further includes a first sound-absorbing element arranged on the inner bottom wall surface of the support box, and a support plate which is arranged on top of the first sound-absorbing element. The load transfer element protrudes from the first building element and into the support box through the support box opening. A filling area is molded with a filling material. The filling area includes the support box and an area between the first building element and the second building element.

A mounting clip (1) for the floating mounting of wall and ceiling panels consisting of composite wood materials, said panels being connected to one another without adhesive by corresponding locking profiles to form a wall or ceiling covering and being fastened to a substructure. The mounting clip has a base board (2), a receiving portion (4) formed in one piece with the base board and intended for engaging in a locking profile of a panel, wherein the receiving portion has a distancing piece (5) arranged as far as possible perpendicularly to the plane of the base board, and a contacting piece (6), which adjoins the distancing piece and is arranged as far as possible parallel to the plane of the base board, and a slot (8) is provided in the base board for fastening the mounting clip to a fastening means on the substructure the slot can be at least 1.5-4 cm long and extend transversely with respect to the contacting piece.
