<p>A shoring or scaffold for construction, maintenance and other work, using stacked scaffold sections of a demountable type and having a heighth adjusting construction is provided. Each section has a pair of spaced-apart end frames that are demountably cross-connected with respect to each other and the end frames of upper and lower sections have a telescopic adjustable relation to meet heighth requirements. To provide strength and support rigidity, dual-tire bracing members are utilized to extend from the end frame of a lower section across and in an interconnecting relation with an opposed and frame of an upper section. A simple adjustment of the bracing members in conformance with vertical adjustments made between upper and lower sections is accomplished by utilizing members that at one end have a gooser pivot mounting on a horizontally extending connecting member of a frame of one section and that at the other end have a latching arm which is provided with a group of spaced-apart latching hole portions whose spacing is proportioned to vertical adjustment positions between the upper and lower sections. The latching hole portions are adapted to selectively detachably latch with a single latching pin means which is carried in a protected relation on an inwardly offset, short length or secondary leg member of the opposed frame of the other section. This enables the use of a single brace member for different heighth adjustments of stacked sections.</p> |
