    • An angular, slidable corner connector for securing the corners and joining of a pair of flange frames for ductwork. The frames are formed of transversely aligned edge members and the corner connectors serve to reinforce and connect sheet metal ducts. Each frame edge has longitudinally directed channels. The corner connector is capable of being formed on site. The corner connector comprises two separate legs that are held together. A first leg has a transversely extending slot formed at one end thereof, the leg and the slot being formed from a single piece of material. The second leg has an end slot stop. The corner connector is formed by sliding the second leg through the transversely extending slot in the first leg until the end slot stop abuts against the second leg, the overlapping portions of the first and second legs form the apex of the corner connector.
    • 一个角度可滑动的角接头,用于固定角部,并连接一对用于管道系统的法兰框架。 框架由横向对准的边缘构件形成,并且角连接器用于加强和连接金属板金属管道。 每个框架边缘具有纵向导向的通道。 角接头能够在现场形成。 拐角连接器包括保持在一起的两个独立的腿。 第一腿部具有形成在其一端的横向延伸槽,腿部和狭槽由单件材料形成。 第二条腿有一个端槽停止。 角连接器通过使第二腿部滑动通过第一腿部中的横向延伸的狭槽而形成,直到端部狭槽抵靠第二腿部,第一和第二腿部的重叠部分形成角连接器的顶点。

    • A cable clamp-bracket combination for rigidly connecting to an item to be suspended, especially a HVAC duct suspended from the ceiling of a structure. The combination utilizing, e.g., a commercially available cable clamp rigidly but removably connected to the clamp in a position where openings in the bracket surfaces mate with the cable channels through the clamp and a slot through the bracket mates with a clamp release projection on the clamp. The cable clamp includes a clamp clutch adjacent each cable channel for holding a support cable. The combination resulting in a rigid connection between the clamp and the item (e.g., duct) and a non-slip connection between the supporting cables and the item. The bracket can be formed from a flat plate having preformed openings and connecting elements by bending the plate into the desired form for holding the clamp and being securable to the, e.g., duct.
    • 一种电缆夹支架组合,用于刚性地连接到要悬挂的物品,特别是从结构的天花板悬挂的HVAC管道。 该组合利用例如市售的电缆夹,其刚性地但可拆卸地连接到夹具,其中支架表面中的开口通过夹具与电缆通道配合,并且穿过支架的狭槽与夹具上的夹紧释放突起配合 。 电缆夹包括邻近每个电缆通道的夹紧离合器,用于保持支撑电缆。 该组合导致夹具和物品(例如管道)之间的刚性连接以及支撑电缆和物品之间的防滑连接。 支架可以由具有预成型开口的平板和连接元件形成,该板通过将板弯曲成用于保持夹具并且可固定到例如管道的所需形式。

    • There is provided a unitary, strike drop-in anchor where the individual parts are permanently held together to avoid misplacing any such individual part. The anchor comprises an anchor body with a central bore, the first end of the bore being threaded and having a constant internal cross-section for the length of the threaded portion. The exterior of the anchor body, and the central bore, have a decreasing bore towards the second end of the anchor body beyond the threaded portion. A threaded bolt with an internal central bore and a preferably polygonal drive head, and external threads extending from the drive head to the second end, has a strike tool extending through the central bore.
    • 提供了一个单一的罢工落地锚,其中各个部件永久地保持在一起,以避免任何这样的单独部件错位。 锚固件包括具有中心孔的锚固体,孔的第一端是螺纹的并且具有用于螺纹部分的长度的恒定的内部横截面。 锚固体的外部和中心孔具有朝向锚固体的第二端的减小的孔,超过螺纹部分。 具有内部中心孔和优选多边形驱动头的螺纹螺栓以及从驱动头延伸到第二端的外螺纹具有延伸穿过中心孔的打击工具。
