A framework section having a connection region which is formed on the end face of at least one of its two ends. The connection region can be connected to the connection region of a further framework section. The framework section can include two upper chord sections and two lower chord sections, which extend parallel to one another in the longitudinal direction of the framework section and are connected to one another by connecting struts such that they define a cuboid space. The upper chord sections and the lower chord sections can have a tubular cross section, wherein the upper chord sections and the lower chord sections can also be configured to transition from the tubular cross section into an I-shaped cross section in the connection region.

A building structure that can be assembled easily with high assembling precision is provided. The building structure of the present invention is a building structure for transmitting a load on a roof to a post, and includes a unit (10) joined to a post (20). The unit includes three or more first beams arranged in parallel in one direction and three or more second beams arranged in parallel in another direction intersecting the one direction. Each first beam and each second beam has a truss structure. In a section where the first beam intersects the second beam, an upper chord of the first beam is disposed on an upper chord of the second beam and is joined to the upper chord of the second beam via a joining member, using a fastener. In the section where the first beam intersects the second beam, a lower chord of the first beam is disposed on a lower chord of the second beam and is joined to the lower chord of the second beam via a joining member, using a fastener.

A joint connection structure of a building framework includes a column assembly including a column and a pair of side plates attached to the column on opposite sides of the column and extending laterally outward from the column. A beam assembly includes a beam having an end portion received between the side plates. At least one of the column and the beam has an opening in an area between the side plates to provide access for bolting at least one of the side plates to one of the column and the beam. The opening is free of a fastener extending through the opening when the column assembly is attached to the beam assembly.

A wall/roof panel includes (a) a façade that has (i) an outer surface that defines a front surface of the panel and (ii) a rear surface and (b) a structural element connected to and supporting the façade.

An apparatus comprises a solar panel or solar tile; and a pultrusion fiber reinforced polymer (PFRP) bracket connected to the solar panel or solar tile. The PFRP bracket mounts the solar panel or solar tile on a roof, and is configured to elevate the solar panel or solar tile a sufficient amount above the roof to enable airflow to occur under the solar panel or solar tile. The PFRP material comprises fibers embedded in a resin matrix. Exemplary fibers are glass, carbon, and synthetic fibers. PFRP products can be formed using a pultrusion method that eliminates outgassing. An intumescent fire barrier can be applied to the PFRP to meet National Fire Protection Association fire endurance codes and standards.

A grid framework structure configured to support one or more load handling devices includes a grid structure including a first set of grid members extending in a first direction and a second set of grid members extending in a second direction, the second set of grid members running transversely to the first set of grid members in a substantially horizontal plane in a grid pattern containing plural grid cells; plural vertical uprights supporting the grid structure; and an adjustable grid levelling mechanism for adjusting the level of the grid structure.

A standardized structural metal plug assembly that, when welded to metal columns and beams, allows to join them together into a bi-axial moment connection without bolts or on-site welding. The plug is assembled in a gravity and interlocking fashion. It is composed of one flange cruciform joint that works as a “male” outward component that channels the beam's “female” inward bracket into its seated and locked position. The column terminals also act as “female” inward component that slips and seats over the flange cruciform joint ends. All the components are lock-in-place to the flange cruciform joint due to various mechanical locking latches attached to the beam brackets and column terminals.

The present invention relates to a press-fit nut for an assembly, a press-fit nut-bolt assembly, and a method of constructing a steel-concrete composite structure using same, wherein a process is simple and a base material does not become deformed during an installation process. The press-fit nut-bolt assembly of the present invention includes a press-fit nut, a stud bolt, a counter nut, and a washer. The press-fit nut includes: a head part formed in a typical nut shape; and a press-fitting part that is formed extending from one of the two surfaces of the head part so as to have an outer diameter less than that of the head part, and that is inserted, through press-fitting, into a base material (M) that is an object requiring fastening. A hollow having threads is continuously formed in the head part and the press-fitting part. The stud bolt includes a body part that is coupled to the press-fit nut by passing therethrough, and a pin tail which is formed extending from an end of the body part and to which a mechanism for rotating the body part is coupled. The body part includes a first threaded portion and a second threaded portion which are formed on the outer surface of the body part along the lengthwise direction of the body part and spaced apart from each other.

A structural steel member connecting assembly includes a first connecting member and a second connecting member. The first connecting member is pivotally connected to a positioning portion of a first structural steel member and therefore can be swung. The second connecting member is pivotally connected to the first connecting member such that the two connecting members are rotatable with respect to each other. The second connecting member has a fixing portion coupled with a second structural steel member such that the longitudinal directions of the two structural steel members intersect. With the second connecting member rotatable with respect to the first connecting member, the installation angles of the two structural steel members can be easily changed in order to make a stable engineering structure. The structural steel member connecting assembly features convenience of, and flexibility in, use and has extensive applications.

A modular factory building, comprising a plurality of modules (10), the module (10) including a framework (11) provided with an apparatus installation area for installing process equipment (13) and/or utility equipment (14), an air duct system, a pipe system and a cable tray system, wherein the air duct system, the pipe system and the cable tray system are arranged on the framework (11) and are connected with the process equipment (13) and/or the utility equipment (14). The afore-described modular factory building is capable of improving the construction efficiency, reducing the construction period, and saving the construction cost.
