A prop-brace coupler has a first section configured to be selectively connected to a vertical prop member of a construction platform that includes a vertical spacing member and a diagonal bracing member. The prop-brace coupler also has a second section configured to be selectively connected to the vertical spacing member and to the diagonal bracing member.

A rigging system comprising a plurality of members including: a first hexagonal support piece comprising: six side members, six rod clamps, each one of the rod clamps being configured to receive and hold a rod piece and positioned between and connecting two neighboring ones of the side members, the each one of the rod clamps comprising: a gap open to outward from a center of the first hexagonal support piece, a latch configured to close the gap at least in part to hold the rod piece within the gap, a set screw hole configured for a set screw to be inserted to tighten the latch, and a rear hole configured for a screw or a bolt to be inserted toward the center of the first hexagonal support piece, and at least one side hole; a first set screw having a cross-section of size and shape configured to fit closely within a cross-section of the set screw hole; and a first connection bolt having a cross-section of size and shape configured to fit closely within a cross-section of the at least one side hole, wherein the plurality of members have a plurality of configurations of structural support, is disclosed.

A method and apparatus for assembling a hanging scaffold system within the aft pressure bulkhead area of an aircraft to provide access to the pressure dome without contacting the pressure dome. The hanging scaffold system comprises a group of horizontal supports to support at least one floorboard. A group of vertical supports is connected to and extends perpendicularly from the group of horizontal supports. A clamping device is attached to each vertical support of the group of vertical supports and further engages an attachment point on an internal structure of an aircraft.

A scaffolding assembly is disclosed. The system includes scaffolding poles joints (or fittings) for releasably securing the poles at cross-over points. Each scaffolding joints has an inner body member and two movable outer clamping members to clamp the poles to the body member at the cross-over points. The body member also has as a mounting for a safety connection member which projects laterally the scaffolding poles towards an operative. The safety connection member can be connected to a safety tension member from the operative such that a safety connection point is available at each of the scaffolding joints.

During erection of a scaffolding use is made of a coupling device with a base part (20) which is connected temporarily, but reliably, to a distal section of a ledger element (10) and to a coupling part (30) extending from the base part (20). The coupling part (30) comprises at the outer end a hook (35) which is placed round a subsequent upright (5) of the scaffolding in order to thus make a secondary connection thereto, while a primary connection (9,11) between the ledger (10) and the upright (5) is only completed later.

One cylindrical pipe is inserted into the hollow cylindrical portions of first and second holders made of hard plastic, and the other cylindrical pipe is inserted into the hollow semi-cylindrical portions. The first and second pipe holders are butted together at butt surfaces, respectively. The cylindrical pipe inserted into the butted hollow cylindrical portions is held in the hollow cylindrical portions using a clamping tool, and the cylindrical pipe inserted into a cylindrical portion that becomes hollow cylindrical by butting is held in the hollow semi-cylindrical portions using the clamping tool.
