A temporary guardrail for an unprotected staircase is assembled and installed using prefabricated sections. One section is a safety section that includes an adjustable length upper railing, with a pair of balusters respectively hinged to each end of the upper railing. Another section is a support section having an adjustable length lower railing that is engaged between the balusters of the safety section and which, when assembled with the safety section, is oriented parallel to the upper railing. The safety and support sections are then stiffened to account for an incline angle that is defined by the staircase. Also included are structures which can be engaged with the temporary guardrail to stabilize it on the staircase.

A handrail pivot joint facilitates the use of handrail sections having square-cut ends, rather than miter cuts, at transitions between flat and sloped sections. Handrail sections have an adjustable angle via the pivot joint, allowing for precise alignment with the adjacent structures, such alignment between the pitch of stairs and the pitch of the handrail. The pivot joint also presents a clean appearance and a robust connection between handrail sections.

Disclosed is a wood frame using a water soluble adhesive and a manufacturing method thereof. The wood frame is manufactured by coating a metal frame with a wood-plastic composite after application of the water soluble adhesive to the metal frame, and may thus have internal rigidity of metal and excellent external flexibility, elasticity, water resistance and corrosion resistance, have an eco-friendly texture like natural wood and prevent deformation due to thermal expansion.

An angle-adjustable post assembly for supporting a rail panel on a stairway includes a post portion that is a generally hollow rectangular tube and a pivot rod that extends laterally from the post portion. The pivot rod is cylindrical to allow pivoting adjustment to position the post portion in a vertical orientation for multiple incline angles. The angle-adjustable post assembly also includes a base portion defining a plurality of first through holes, each of which is configured to receive a first fastener. A top bracket with an arcuate portion that is sized and shaped to correspond to the circumference of the pivot rod defines a pair of second through holes, each configured to receive a second fastener.

A support structure for handrail post repair, the support structure comprising a support frame having a flange base for stabilizing the support structure and a tube comprising a rail end and a ground end such that the tube is connected to the flange base at the ground end, a support rod attached to the tube for securing a handrail post and at least one locking element extending through the tube.

A guardrail formed of folded sheet metal includes a face panel, a top panel extending rearwardly from the top edge of the face panel, a return panel extending downwardly from a return edge of the face panel, the return edge being opposite the top edge, and an end panel extending rearwardly from a side edge of the face panel and having the same width as the distance as the distance between the front surface of the face and the back surface of the return panel, the end panel having an upwardly extending upper portion being narrower than the main body of the end panel so that it is freely received in a downwardly facing channel formed by the face, top and return panels.

A modular platform system utilizing a number of components including a platform. The platform is configured so that each of the components may interchangeably connect to any side of the platform. The components include, for example, handrails and stairways, as well as other platforms. The platform and most of the components are formed from single, continuous pieces of metal.
