A wall bracing apparatus for mounting between a wall and the floor during construction. The wall bracing apparatus includes a tube that is mounted to a wall-mounted device and a floor-mounted device. The wall-mounted device has a backing plate and a front plate on opposite sides of the wall. A t-bar having a head at one end and a shaft through which a hole is formed extends through aligned central apertures in the plates and a wedge is inserted in the hole near the front plate end of the t-bar. A pair of ears on the front plate has aligned holes through which a pin extends that is also inserted through the tube. A duplicate of the front plate can be mounted to the floor and the opposite end of the tube can pivotably mount to the ears thereof.
