Object retainer for upright concrete construction forms

摘要

A retainer device for holding objects within recesses provided on form liners which are attached to the inside surface of substantially upright concrete structural forms. The retainer device is attached to the form liner to hold the object against the liner so that after the concrete has been poured and set and the forms stripped, the objects will be exposed in the finished surface of the structure. Various retaining devices such as clips having enlarged heads and elongated stems with friction enhancing devices intended to be inserted or attached to the form liner so as to hold the clip in a secure relationship with respect to the objects. Another embodiment of the retainer device is a spring-biased clamp having a body encased within the form liner so that the clamp ends grip the sides of the object. In another embodiment, an elastic band is secured to the form liner ridge provided between recesses. The band is held in the ridge so that a dowel or pin can pass through the elastic loop and contact the objects to provide the holding force. A further embodiment is a flexible elastomeric cuff or receptacle having a thin outer membrane which has a thickness no more than one-half of the grout area between the bricks provided in the finished surface whereby the cuffs can be attached to the form to provide the retaining device and the liner receptacle for holding the brick in position during the pouring process.
