Apparatus and method for improving quality of elevated concrete floors |
摘要 |
A device and method for measuring an initial camber of a beam includes a support member positionable at a beam of a structure. The support member includes a laser receiver for receiving a laser reference plane at a first location when the support member is positioned at an end of the beam and at a second location when the support member is positioned at a central region of the beam. The initial camber of the beam is then derived by determining a difference between the first and second locations on the laser receiver. A loose shoring system provides an adjustable length support section and a positive stop for limiting deflection of the beam at a desired amount generally equal to the measured initial camber of the beam. The stop is adjustable to set a gap approximately equal to the expected deflection or initial camber of the beam as desired.
