摘要： An easily assembled concrete form including a plurality of elongated wall members manufactured by roll forming and connected together to define an enclosure. Each wall member has a first end and a second end, an inner surface and an outer surface. Attached to the inner surface of the wall member at the first end is a U-shaped key having legs extending beyond the first end of the wall member. Attached to the inner surface of the wall member at the second end is an interlocking bracket having two vertically spaced slots for receiving the legs of the U-shaped key to connect adjacent wall members together. One of the slots is enlarged for also receiving an extending flange from a support bracket to frictionally maintain the U-shaped key and interlocking bracket in a locked relationship.
摘要翻译：一种易于组装的混凝土形式，其包括通过辊轧成型制造并连接在一起以限定外壳的多个细长壁构件。每个壁构件具有第一端和第二端，内表面和外表面。在第一端处附接到壁构件的内表面的是具有延伸超过壁构件的第一端的腿的U形钥匙。在第二端处附接到壁构件的内表面的是互锁支架，其具有两个垂直间隔的槽，用于接收U形钥匙的腿以将相邻的壁构件连接在一起。其中一个槽被放大，用于从支撑托架接收延伸的凸缘以摩擦地保持U形键和互锁支架处于锁定关系。
