A roofing anchor configured to be removably secured to a seam of a roofing panel includes a first segment having a first flange configured to contact a first side of the seam upon closing the roofing anchor, and a second segment opposing the first segment, the second segment having a second flange opposite the first flange, the second flange configured to contact a second side of the seam upon closing the roofing anchor. The roofing anchor also includes a hinge mechanism configured to open the roofing anchor to separate the first flange and the second flange by a distance greater than at least a top of the seam, and to close the roofing anchor to bring the first flange and the second flange in contact with the seam. The roofing anchor further includes a securing mechanism configured to apply a compressive force on the seam.

The invention relates to a holder (1) for a guide shoe (14) of a climbing system for concrete formwork having a hold-down (2) which can be fastened to a floor, and a slide part (3), which is movably guided in the hold-down (2), such as in the form of a support arm. According to the invention, the holder (1) is designed having a self-locking drive, such as a screw drive (10) for moving the slide part (3), which secures the slide part (3) against unintentional movement.

Various implementations described herein are directed to a scaffold bracket. In one implementation, the scaffold bracket may include a mounting bracket having a first face and a second face opposite of the first face. The scaffold bracket may also include a first scaffolding node attached to the first face and configured to couple to a first member. The scaffold bracket may further include a second scaffolding node attached to the first face and configured to couple to a second member.

A standing seam mounting bracket and a method of using two or three to provide attachment points along a standing seam roof is provided. The standing seam mounting brackets enable complementary use of commonly-owned equipment for enabling roof maintenance and construction. The standing seam mounting brackets may be used in concert with roof jacks, roof ladders, scaffolding members and the like that are commonly owned by most contractors so as to facilitate safe and easy horizontal and vertical movement along the sloped roof.

To ensure maintenance operations for an architectural structure using a mast climber without any limitation on the stability of a mast and locations where a mast can be erected. A side wall 101 of an architectural structure 100 is fitted with a fixing member 130 at a level higher than the ground 500. The fixing member 130 is fitted with fixture studs 132. A mast 200 is erected on the fixing member 130 with its lower end secured to the fixture studs 132. A climbing work platform 210 that travels up and down the mast 200 is fixed to the mast 200. A worker performs maintenance operations on the climbing work platform 210.

The shingle installation jack devices may be mounted once at a first roof level, providing support for the walk board. When installation or repair of the shingles is complete at the first level of the roof, the shingle installation jack devices may be operated in tandem to raise the level of the walk board to a second level of the roof. Shingle installation and/or repair may then be carried out at this second roof level without the need to re-mount the walk board supports at the second level. The shingle installation jack devices may also be run in reverse to lower the walk boards. The shingle installation device includes a frame and utilizes a winch motor to adjust the effective length of a cable and thus adjustably raise or lower the walk boards to any desired roof level.

A rack construction assembly for building a storage rack includes a plurality of bracket units. Each of the bracket units has a plurality of channels therein to insertably receive dimensional lumber. Thus, the dimensional lumber is arranged to form a rack for storing objects. Each of the channels corresponding to each of the bracket units is oriented at right angles with respect to each other. Thus, the dimensional lumber corresponding to each of the channels defines an X axis, a Y axis and a Z axis of the rack.

A temporary shield erected between two flanged structural members of a bridge or other structure, a kit therefor, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift up of the shield.

This invention relates to a stabilizer post for a scaffold hoist comprising a post extending from an upper end to a lower end, an L-shaped upper angle insert comprising an upper contact plate extending down to a substantially perpendicular upper insert plate, an L-shaped lower angle insert comprising a lower contact plate extending up to a substantially perpendicular lower insert plate, and wherein the upper angle insert is attached adjacent to the upper end of the post so that the upper insert plate is below the upper insert plate and substantially perpendicular to the post and the lower angle insert is attached at the lower end of the post so that the lower insert plate above the lower contact plate and substantially perpendicular to the post, and the lower contact plate and the upper insert plate are substantially parallel to one another. The stabilizer post is attached to a wall by inserting the lower insert plate into a lower wall cut, inserting the upper insert plate into an upper wall cut, and attaching the lower insert plate to the bottom plate and the upper insert plate to the top plate.
