摘要： A connection system is provided for use with scaffolding to secure laterally extending support members to upright standards. Latching rings permanently secured at intervals along the upright standards are provided with primary latching openings, each of which has a central region of limited breadth with oppositely directed narrower radial elongations of uniform width throughout. The radial elongations of the primary latching openings are located so as to reside in vertical registration with longitudinally elongated apertures formed in flanges of brackets that are secured to laterally extending scaffold support elements. Wedges are carried by the brackets and can be fully engaged only when the laterally extending support members are in precise, orthogonal alignment relative to the upright standards. Preferably, secondary latching ring openings are provided to accommodate diagonal braces to enhance the rigidity of the scaffolding support.

摘要： An improved walk-through scaffolding frame is constructed of components which may be assembled together to form an erected frame and disassembled to pass through a narrow opening such as a manhole or some other narrow access opening to a larger enclosure. The improved walk-through scaffolding is constructed with a pair of generally triangular-shaped upright support members and a connecting crosspiece. The upright support members each define a single downwardly directed tubular leg as well as upwardly extending inner and outer support posts. The crosspiece includes downwardly directed connectors which telescopically engage both the inner and outer support posts of each of the pair of upright support members and an upwardly directed connector at its outer extremity for engaging a downwardly directed leg of another walk-through frame located thereabove. The upright support members and the crosspiece may be quickly and easily disassembled without tools to pass through very narrow manhole-type openings and reassembled without tools to erect scaffolding.

摘要翻译： 改进的步行式脚手架框架由可组装在一起以形成竖立框架并拆卸成通过狭窄的开口（例如人孔或一些其他狭窄的进入开口）的部件构成为较大的外壳。 改进的步行式脚手架由一对大致三角形的直立支撑构件和连接横档构成。 直立支撑构件各自限定单个向下指向的管状腿以及向上延伸的内部和外部支撑柱。 横档包括向下定向的连接器，其可伸缩地接合一对直立支撑构件中的每一个的内支撑柱和外支撑柱，并且在其外端处具有向上指向的连接器，用于接合位于其上方的另一步道框架的向下指向的腿。 直立支撑构件和横档可以快速且容易地拆卸而不需要工具通过非常狭窄的人孔式开口并重新组装而不用工具直立脚手架。

摘要： The present invention is an improved construction perimeter guard stanchion. A dual adjustment system performs both coarse and fine adjustments to tightly clamp a pair of jaws at the lower end of the stanchion upon the edge of a floor slab in an elevated, unfinished building structure. A coarse jaw adjustment sleeve formed of a short section of hollow steel tubing is coaxially disposed about an outboard support member in sliding engagement therewith. The coarse adjustment sleeve has one or more perforations therethrough so that a locking pin can be passed through it and through aligned openings in the outboard support member. A fine adjustment screw member is disposed coaxially within a vertical rail support tube and may be rotated by lever arms to move the upper jaw closer to or further from the lower jaw. Adjustment of the fine positioning mechanism is performed by manipulating handles at the top of the vertical rail support tube. A workman installing the stanchion thereby does not have to stoop over to operate a clamp located down near the concrete slab.

摘要翻译： 本发明是一种改进的施工周边防护支柱。 双调节系统执行粗调和精细调整，以在升高的未完成的建筑结构中的地板的边缘上紧紧地夹紧在支柱的下端的一对钳口。 由短的中空钢管形成的粗颚调节套筒与外部支撑构件同轴地设置，与其滑动接合。 粗调套筒具有穿过其中的一个或多个穿孔，使得锁定销可以穿过它并且穿过外侧支撑构件中的对准的开口。 微调螺丝构件同轴地设置在垂直导轨支撑管内，并且可以通过杠杆臂旋转以使上钳口更靠近或更远离下钳口。 精细定位机构的调整是通过在垂直导轨支撑管的顶部操纵手柄来进行的。 因此，安装支柱的工人不必弯腰操作位于混凝土板附近的夹具。
