摘要:
A telescopic edge protection post arrangeable between a floor and a ceiling, comprising outer and inner tubes, each comprising a bottom end and a top end, the inner tube extending into the outer tube and being movable with respect thereto between an extended position and a collapsed position. The post further comprises a locking mechanism to lock the inner tube with respect to the outer tube in the extended position, and a tensioning unit arranged at the top end of the inner tube. The tensioning unit comprises a tensioning element having a primary and secondary tensioning portions, wherein tensioning of the secondary tensioning portion requires a lower force than the primary tensioning portion, allowing tensioning of the secondary tensioning portion by extending the telescopic edge protection post by hand into engagement with the floor and the ceiling. Further, the primary and secondary tensioning portions each comprise a compression spring.

A partition mount system includes an integrated plunger assembly. The integrated plunger assembly is constructed and arranged to be integrated into an interior of an end of an extension pole, for example a standard telescoping extension pole. Mounting of the plunger in an interior portion of the pole in this manner provides for a sleek design that is relatively lightweight. Assuming that the pole in which the anchor is mounted is part of a telescoping pole system, the anchor and plunger do not interfere with full travel of the interior pole with respect to other poles in the telescoping system. In this manner, operation of the telescoping pole system is not inhibited by the integrated plunger assembly.

Precast wall systems and methods for constructing a high-rise building using the precast wall system is disclosed. In one embodiment, the system includes a plurality of interconnected precast panels, each having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel. A first of the precast panels has a first column member half defining a right side of the first panel, a second of the precast panels has a second column member half defining a left side of the second panel such that, when the right side of the first precast panel and the left side of the second precast panel are disposed horizontally adjacent to each other, the first column member half and the second column member half collectively form a column member.
