发明名称 Attached pin for poured concrete wall form panels
摘要 A sliding pin is selectively mounted to the back of a poured concrete wall form panel for use in combination with a standard wedge for coupling adjacent panels of the concrete wall form together. The pin when attached to the panel conveniently slides relative to the panel to and between engaged, stowed and retracted positions. Furthermore, the pin is captured within a carrier and is rotatable for convenient access to the slot in the shank of the pin. The components of the system are durable to withstand impact blows by a hammer or other tool, do not require specialized hardware for their use and will not be fouled by splashed concrete or other debris.
