摘要:
A building is constructed from a plurality of rectangular wall sections secured to one another. At least some wail sections are formed of an upper and a lower beam, vertical studs extending between the upper and lower beams and a wall panel secured to the beams and to the studs. In the invention, each beam is formed of an elongate metal sheet folded through a right angle about at least one longitudinally extending line to define at least a horizontal first plate, and a vertical second. A plurality of separately formed sheet metal brackets are secured to at least one of the plates of the folded metal sheet at preset distances from one another along the length of the beam and secured to the ends of the studs.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. At least one of the lateral support bands is a relatively softer steel having greater elongation properties, while having lower yield and tensile strengths. The balanced properties better distribute the force of a falling object to the respective members of the fall protection system so as to limit the force which must be tolerated by the suspension fabric, such that the system can catch and hold a dropped test load, or a worker falling onto such system, without catastrophic failure of the suspension fabric.

A building structure including a first building member and a second building member may be connected by a plurality of fasteners, each fastener having a head, a threaded portion having a through hardness of between HRB 70 and HRC 40, a thread-forming portion of at least HRC 50 hardness enabling the fastener to form threads in at least the second steel building member, and a fluted lead portion of at least HRC 50 hardness with a nominal diameter between 70 and 95% of major diameter, such that the fastener is capable of providing a ratio of strip torque to thread-forming torque of at least 2.7 and a ratio of strip torque to drive torque greater than 6.0 when the second steel building member having a thickness of 0.25 inch and the fluted lead portion having at least one diameter within nominal diameter between 80 and 98% of major diameter.
摘要:
A building insulation system for roofs and walls supported from the interior side of the building, which eliminates thermal bridges and bottom side ceiling fasteners to support the insulation system materials during the insulation and exterior sheeting process of the building construction. The insulation system creates an air gap space layer in roofs and in walls between the exterior wall and roof sheeting panels and the interior sheet material, which supports the insulation material layer. An air gap space enables active solar energy collection and its use to reduce the overall purchased energy for operation of the building. The insulation system preferably includes a support sheet material, a sheet material tensioning devices, an insulation material layer, insulation hanger retention devices, heat and air collection and distribution ducts, dampers, louvers, pipes, dehumidification and condensate collection devices used in the air gap layers of the building to improve the building energy efficiency.

Steel frames formed of rolled steel I-beams are connected by steel framed wall panels spanned by steel studs, and covered by steel framed roof panels spanned by steel purlins, making a structural frame completely formed of steel components bolted together. All components are precut and predrilled before transport to a construction site. A crane is used to raise steel frames and steel framed roof panels into position for bolted assembly, reducing construction times to absolute minimums. Entire structure is virtually lightning-proof, wind-proof, and earthquake resistant.

The present invention provides a joining structure of a roof truss using thin light-gauge shaped steel. In a joining structure for joining a subsidiary roof with a main roof, a valley bracket formed by bending a thin steel sheet is inserted and disposed in the longitudinal valley direction of a joining member for joining a rafter forming the subsidiary roof with a truss or a rafter forming the main roof. In a joining structure in which a roof truss upper chord member or a rafter intersects a wall on the upper surface of the wall, a bracket formed by bending a thin steel sheet is disposed at the intersection of these members and fixes the roof truss upper chord member or the rafter to the wall. In a joining structure for the connecting top of the roof truss upper chord member or the rafter, a thin steel sheet member is disposed at the connecting top to fix an end of the roof truss upper chord member or the rafter with an end of a strut, and a box-shaped bracket formed by bending a thin steel sheet to have box-like receiving sections is provided at a top of the thin steel sheet member, for fixing top cleat members.
摘要:
A truss system and method for use in constructing a building structure comprising a first and second truss member connected to one another a distal end thereof thereby forming a peak joint. A cross bar is connected to each of the first and second truss members at an under side of the peak joint and a sleeve is connected to each of the first truss member and the second truss member at an end opposite the peak joint. Upon securing the cross bar to the first and second truss members, a truss unit is formed wherein a support member is received by the sleeves of each one of the truss units, and upon securing the support members to one another, the truss units form a frame of the building structure.

A metal frame for a building structure includes a structural beam, such as a truss, and a tubular purlin or trellis attached to the beam. The tubular purlin includes a configured end matably engaging a side of the beam and an attachment tab extending longitudinally from the configured end. The configured end and the attachment tab both are integrally formed from material of the tubular purlin. The structural attachment tab supports the configured end on the structural beam and structurally attaches the tubular purlin to the structural beam. In one form, the tubular purlin includes a wall section that covers an open end of the tubular beam. In another form, the configured end defines an angled recess setting the particular orientation of the beam relative to the purlin. In yet another form, interlock hooks are provided on the attachment tab.
