A combined member, comprising a communication rod (1) and a connecting rod (2), wherein the connecting rod (2) comprises a rod body (2.1) and a connector (2.2), the connector (2.2) being a fastening connector (3) or a sleeving connector (4), the rod body (2.1) of the connecting rod (2.1) and a rod body of the communication rod (1) being of a strip-shaped structure, the connecting rod (2) being connected to the communication rod (1) by the fastening connector (3) or the sleeving connector (4), the axis of the connecting rod (2) intersecting that of the communication rod (1) connected thereto. The combined member has the advantages of high bearing capacity, and convenient construction.

A connection apparatus may be used to connect truss sections or other objects. A connection segment is mounted on each truss to be connected. Each of a first and second connection segment has an opening, in alignment with each other to receive a fastener. The opening of the first connection segment allows the fastener to pivot. The second connection segment has a side opening which allows the fastener to pivot inside and outside the body of the second connection segment. The fastener has a threaded end and a locking end. The locking end may be secured against an outer surface of the second connection segment. In the locked position the locking end of the fastener engages the outer surface of one the second connection segment and the fastener is prevented from rotational or axial movement. The connection segments are thus fixed relative to each other as are the truss sections on which the connection sections may be mounted.

A modularized framework structure of a three-dimensional truss structure is obtained as a result of making unit modules and interconnecting the unit modules. Each of the unit modules is made of frames, having elongated joining surfaces and connected mutually at end portions, to conform to a regular tetrahedron or octahedron. The elongated joining surfaces are obtained as a result of planarly truncating surfaces of edges of the frames corresponding to ridgelines of the regular tetrahedron or octahedron such that the elongated joining surfaces can be joined mutually, and the elongated joining surfaces are oriented orthogonally to perpendiculars drawn from the center to the corner centers of the elongated joining surfaces to form a Tetra- or Octa-module. The unit modules as the Tetra- or Octa-module are interconnected by joining mutually the elongated joining surfaces of the frames thereby to form the three-dimensional truss structure.

A system and method for constructing a modular frame structure is provided. The system includes brackets to which structural members can be fastened to form a building frame. Each bracket has between three and six attachment elements positioned at right angles to an adjacent attachment element. A structural member, such as a beam or post, can be fastened to each attachment element to form a moment resisting connection. The brackets are manufactured in standard sizes and configurations so that a set of brackets can be used to construct a modular frame structure of a desired size and configuration.

Steel connections of a column and beam(s) for a building structure with heavy loads are presented. First option is a single plate that is inserted through a slot in the W column flange(s) and attached to the column's web and flange(s). In the field, a W beam with a flange slot is inserted through the column connector plate and attached. Option 2 is the same as Option 1, except, two connector plates are provided for attachment to the beam web and flanges. Thirdly, brace frame connections are presented.

A support assembly for providing a high degree of lateral strength and integrity is presented herein. The support assembly includes a beam support bracket having at least one laterally disposed elongated portion that is slidingly engaged with a corresponding lateral beam. The elongated portion of the beam support bracket is defined by spaced apart first and second support plates each including oppositely disposed edges which will mate with corresponding ledges, protrusion or reinforced corners within the lateral beam.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

The present application provides a prefabricated structural system and an assembly method thereof. The prefabricated structural system may be applied to steel structures, reinforced concrete structures and timber structures. When applied to the steel structures, the prefabricated structural system includes a plurality of steel structure joints and related members. The steel structure joints and related members further comprise: a beam-column connecting sleeve, comprising a first box-shaped steel tube and first C-shaped sleeves extending from and perpendicular to outer surfaces of the first box-shaped steel tube, wherein the first C-shaped sleeve is provided with first wedge shaped recesses at ends of upper and lower flanges thereof; columns, having a column connecting end inserted into the first box-shaped steel tube; main beams, having a main beam connecting end inserted into the first C-shaped sleeve; and main beam fixing steel plates, provided with first wedge shaped protrusions that are tenon-mortise-jointed with first wedge shaped recesses at both sides of the first C-shaped sleeve. In addition to the steel structural construction, the beam-column connecting sleeve of the prefabricated structural system may be further extended to reinforced concrete structures and timber structures.

A building system comprising a plurality of tubes, a plurality of connection nodes comprising tubular sections for connection to the tubes, wherein the tubes are arranged to connect between the connection nodes to form a frame for a building, wherein at least one continuous cavity is formed through at least a portion of the nodes and tubes when the nodes and tubes are connected, the building system further comprising fluid tight seals between the tubes and connection nodes to enable fluid to flow through the at least one continuous cavity.

Fastening means, a preferred embodiment of which is shown in FIG. 2, hasajoist 1 and a locking member 5. The joist 1 has a channel and locking extensions and the locking member 5 has a base 6 and an upstand 7. The base 6 has rounded corners 10. The fastening means is formed such that when it is in use the locking member 5 can be slid into the channel and rotated therein to assume a locking position, such rotation made possible by the rounded corners 10 which, when in use, serve to prevent a rotational impasse between the joist 1 and the locking member 5. The fastening means is formed such that when the locking member is in the locking position it is in a tight fit within the channel and cannot pull out of the channel by reason of obstruction by the locking extensions.
