A steel plate built-up beam for a steel-concrete composite beam, which is for the purpose of forming a steel-concrete composite beam by filing the inside thereof with concrete, includes: a pair of web plates spaced apart from each other; a lower flange provided on the lower portions of the web plates so as to connect the lower portions of the pair of web plates; and upper angles provided on the upper portions of the web plates, respectively, such that one leg of the upper angle is coupled to side surfaces of the web plates, and other leg of the upper angle is formed to bend in directions perpendicular to the web plates.

A truss includes a plurality of truss members, each truss member formed from a unitary folded blank of sheet metal to create a main panel, and proximal and distal flanges and a horizontal panel each extending perpendicularly from the main panel, the proximal flange of a first truss member is connected to the distal flange of a second truss member to form a truss. In one embodiment employing trusses formed of folded sheet metal, a plurality of interconnected truss modules, each truss module including a plurality of truss members, forms a plurality of oppositely extending horizontal flanges that collectively present the top and bottom surfaces of a cantilevered canopy.

The present technology relates to beams having a cross section defining a plurality of channels and assemblies comprising the beams. The beams can be used to form a beam assembly that is installed inside the truck bed of a pick-up truck. A ladder loader and a solar panel assembly can be pivotably secured to the beam assembly along either the driver side wall or the passenger side wall of the truck bed.

The present invention includes a lintel support to aid in lintel repair and/or reinforcement. The lintel support has a body with a top, a bottom, and a height extending therebetween; at least one claw at the top; and a bracket at the bottom. In use, points are dug out of a mortar line above the lintel and the claws of the lintel support are positioned into those points. With the claws so positioned, the bracket will be below the failing lintel. A support beam is placed under the bracket and a jack lift provides uplift at the mortar line where the claws are positioned.

Disclosed herein is a steel thermal stud being capable to provide structural and non-load bearing characteristics. The steel thermal stud with more than one dual flange stud provides additional and separated penetration locations for mounting screws allowing multiple connection points on the screw. The Steel Thermal Stud with multiple stud walls for a fastener to penetrate to prevent the movement of the fastener in any direction, prevent deformation of the stud wall material, prevent fasteners from backing out by having additional contact with less potential movement, provide more pull-out strength, and more strip resistance of the fasteners during installation.

Disclosed herein is a steel thermal stud and method of manufacturing thereof. The steel thermal stud of the present invention can be used in load bearing and non-load bearing applications as a direct replacement for wood studs, however installed the same as traditional steel studs. The steel thermal stud is able to be insulated with a variety of insulation products depending on the application, and the stud discloses a superior thermal and acoustic properties while being much lighter than wood studs.

A truss includes an upper angle assembly; the upper angle assembly including an upper gap positioned in the lower angle assembly; a lower angle assembly, the lower angle assembly including a lower gap positioned in the lower angle assembly; and at least one of: a web member; and a bridge web member. The at least one of the web member and the bridge web member is positioned within the gap of at least one of the upper angle assembly and the lower angle assembly.

A reinforcement-confined circular steel tube member with enhanced end stiffness. Two ends of a first end sleeve are respectively connected to a first end plate and a first connecting annular plate. Two ends of a second end sleeve are respectively connected to a second end plate and a second connecting annular plate. A first end of a circular steel tube passes through the first connecting annular plate to be inserted into the first end sleeve and fixed to the first end plate, and a second end of the circular steel tube sequentially passes through restraint rings and the second connecting annular plate to be inserted into the second end sleeve and fixed to the second end plate. Two ends of each steel bar are respectively provided with a first limit part and a second limit part.

A metal beam with asymmetric section and damage warning function includes a main body; the cross-sectional shape of the main body section defines a neutral axis, and a pressure zone and a tension zone when subjected to a pure bending moment load. Each point of the main body is arranged in a linear relationship with respect to the neutral axis within the elastic range. The cross-sectional shape of the main body section is on both sides of the neutral axis in an asymmetrical arrangement. The section modulus of the pressure zone of the main body section at the maximum bending moment is greater than the section modulus of the tension zone. Before the pressure zone bears a stress reaching the elastic limit to yield and enter plastic deformation, the tension zone has a stress exceeding the elastic limit and yield to enter plastic deformation first, so that the plastic deformation of the yielding tension zone provides a warning about a possibly occurring compressive shear damage of the pressure zone, forming the present invention.

A beam article for a vehicle includes a plurality of separate elongated metal sheets attached together to form generally planar walls of an elongated tubular structure. At least one of the plurality of separate elongated metal sheets has a shear wall that is disposed along a hollow interior of the elongated tubular structure and is attached at opposing walls of the elongated tubular structure. At least one of the plurality of separate elongated metal sheets comprises an edge that abuts a side surface of an adjacent one of the plurality of separate elongated metal sheets to define a non-radiused perpendicular weld corner along the elongated tubular structure.
