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 fractal structure system provides building components with different sizes, which a building component with the next smaller size can insert into or attach to a building component with the next larger size. Each building component has a plurality of channel walls radiating outwardly, and the plurality of channel walls forms a plurality of channels. Each building component further comprises an internal center bore, and the internal center bore includes a plurality of internal center bore corners aligning to said plurality of second channel walls. Different sizes of building components have the same cross sectional profile, which a fractal structure or pattern can be implemented with the different sizes of building components.

The invention proposes a system for constructing a module of a building, including core construction elements (1) that are surrounded by the surrounding construction elements (2A, 2B). The core construction elements (1) each include, in section, a cross including two main arms (6) of equal length which intersect at mid-length at right angle. Each core construction element (1) has a plane of symmetry about the axes of the arms. The main arms (6) of the cross terminate, at the ends thereof, with transverse portions (7). Each surrounding construction element (2A, 2B) is composed of four partial surrounding parts (2A, 2B, 2A′, 2B′) of a generally triangular shape which are assembled around a core element (1). Construction elements forming junction parts (4A, 4B) allow assembling panels (4A, 4B) to form a module of a building in the form of a rectangular parallelepiped volume comprising four corners.

An end cap for a profile rail includes a connector for connecting the end cap to the profile rail and a fastening leg, where the fastening leg defines an opening and where a fastening pin is guidable through the opening to mount the profile rail. The opening has a cross-sectional constriction and the fastening pin is holdable in the opening by the cross-sectional constriction.

There is provided a horizontally and vertically extendable building structure module that includes a panel, a structural frame and one or more beams. The panel may be designed to form or set into a floor, ceiling, wall, window, door or any other components that may cover surface of the building. The structural frame may be designed to provide the structural shape and strength and hold the panels. The beams may be designed to connect and align the structural frame. The horizontally and vertically extendable building structure module is configured to build a building structure without additional structural support. Because of the minimized number of components for the building structure, time and cost for building construction may be reduced.

An extruded profile defining a normal section surface, a horizontal loading direction along the normal section surface and a vertical loading direction along the normal section surface perpendicular to the horizontal loading direction The profile includes a core arranged in a central position at the intersection of the directions, a plurality of arms each including a radial segment radially connected to the core and a tangential segment perpendicularly connected to the radial segment The radial segments of the adjacent arms are perpendicular to each other and each oriented 45° to the horizontal load direction and/or the vertical load direction, and the tangential segments of the adjacent arms are configured to simultaneously support the same load along the horizontal load direction and/or the vertical load direction.

A roof structure adjustable support frame system comprising a plurality of joist rails configured to adjust longitudinally; a plurality of side rails configured to adjust longitudinally between the plurality of joist rails; a plurality of corner rail connectors configured to couple a side rail to a joist rail; and a plurality of adjustable joist rail connectors. The plurality of adjustable joist rail connectors comprise a joist rail attachment configured to removably attach to an end of the joist rail, an extension support member extending longitudinally from a first end of the joist rail attachment, a hook assembly configured to move longitudinally along the extension support member and engage a roof joist to couple the joist rail to the joist; and a movable stop configured to secure the hook assembly against the roof joist.

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.

To provide a building frame for constructing a building, the frame being stronger than reinforced concrete, and being able to be relatively easily assembled at a construction site, without skills, and within a short time. Provided are a building frame and the like, the building frame being characterized by comprising: U-shaped parts that are arranged left and right so as to sandwich a center space in a cross-sectional view; and a connection part that connects top portions, on the center side, of the left and right U-shaped parts so as to form a reverse U-shaped part, wherein the longitudinal edges, on the far side from the center, of the U-shaped parts arranged left and right in the cross-sectional view are shorter than the longitudinal edges, on the center side, connected by the connection part.
