Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.

The present disclosure relates to a common tower configured to be erected adjacent a building structure into construction. The tower comprises spaced apart columns, made of vertically aligned column hollow sections, spacedly and substantially vertically positioned adjacent the building structure, and vertically spaced apart flooring structures releasably and slidably supported by the spaced apart columns using a plurality of sliders. Each flooring structure is being capable of vertical displacement when supported by the spaced apart columns. The tower further comprises an anchoring system adapted to securely engage with the building structure to maintain the spaced apart columns substantially upright, as well as protection structures adapted to surround the flooring structures. A safe and easy erection of the tower using a common tower assembly is described.

A brace for a safety deck is disclosed. The brace comprises a pair of spaced apart wing portions to receive a portion of a standard therebetween and an engagement portion oriented at an angle to the spaced apart wing portions, the engagement portion to engage a portion of a diagonal to position the portion of the diagonal relative to the portion of the standard.

Problem to be solved

To provide an aluminum pipe support having lighter weight and higher rigidity compared to an iron pipe support.

Solution

An aluminum pipe support 1 is configured with two pieces of pins 2A, an inner pipe 3 having an outer periphery formed in any one of a regular hexagonal shape, a regular octagonal shape, and a regular decagonal shape, and having, at a position not subjected to insertion of the pin 2A, a cross-sectional area of 1.96 times or larger than a cross-sectional area at a corresponding position of an inner pipe of a targeted-size iron pipe support, an outer pipe 2 having an inner shape allowing the inner pipe 3 to be inserted into, and having, at a position not subjected to the insertion of the pin 2A, a cross-sectional area of 1.35 times or larger than a cross-sectional area at a corresponding position of an outer pipe of the targeted-size iron pipe support. The upper limits of the cross-sectional areas of the inner pipe 3 and the outer pipe 2 are set so that the total weight of the inner pipe 3 and the outer pipe 2 is lighter than the total weight of the inner pipe and the outer pipe of the targeted-size iron pipe support.

Effects

The specified load bearing capacity is satisfied, and drastic reduction in weight and high rigidity are achieved.

A scaffold apparatus may have a saddle with a platform and two spaced apart parallel sides extending above the platform. The apparatus may also have a beam having a beam flange attached to an end portion of the beam. The apparatus may also have an upright connector with a bottom portion, where bottom portion may have an insert, and a plate attached to the bottom portion.
