Abstract
A waler system includes a number of clamps each of which has a lower leg including a tab with a hole therein which is secured to the wall form of a poured concrete wall system by a standard pin connection. An upper leg of the clamp translates between a loading/unloading position so that a waler beam can be installed easily and conveniently on the clamp attached to the wall form. Each of the clamps is then simply translated into the clamping position by forcing the upper leg downwardly and inwardly toward the beam and the wall form. After the concrete has been poured and the wall cured, the waler system can be disassembled by simply translating the upper leg of each clamp upwardly and outwardly to disengage the waler beam. The transformation is assisted by a spring captured within the upper leg of each clamp.
