    • A modular concrete wall form panel unit comprises a facing panel and a supporting frame of metal structural members having edge faces normal to the panel and flush with its edges. Adjoining panels are quickly fastened together and taken apart by captive T-head fasteners which extend through elongated slots in the edge faces and seat against spring pressure in cammed fittings when the T-head fasteners are rotated. Each fastener is provided with a second compression spring which retracts it within the frame when it is disengaged. Each unit is provided with slots extending across the edge faces of the frame and into the panel face as semicircles so that when adjoining panels are fastened together holes for tie rods are thereby formed.
    • 模块化混凝土墙板面板单元包括面板和金属结构构件的支撑框架,其具有垂直于面板并与其边缘齐平的边缘面。 相邻的面板通过T型头紧固件快速固定在一起,并通过T形头紧固件分开,T型头紧固件在T形头紧固件旋转时延伸穿过边缘表面的细长槽口并抵抗凸轮配件中的弹簧压力。 每个紧固件设置有第二压缩弹簧,当第二压缩弹簧脱离时,该弹簧在框架内缩回。 每个单元设置有跨越框架的边缘面延伸并且以半圆形的方式延伸到面板表面中的槽,使得当相邻的面板紧固在一起时,形成用于拉杆的孔。
