Abstract
A device to brace a door frame (3), to prevent the sides of the door frame buckling when grout or other filler material is used to fill a gap between the door frame and an adjacent wall comprises, a pair of elongate support member (17), for contacting the sides of the door frame (3), upper and lower means (25, 27) coupling the support members together for movement between a retracted position and an expanded position, and means for selectively locking the support members (17) is the expanded position with the support members contacting and bracing the sides of the door frame (3).
Claims16
A device to brace a door frame the prevent the sides of the door frame buckling or otherwise deforming when grout or other filler material is used to fill a hollow region defined by channel members constituting the door frame and/or gap between the door frame and an adjacent wall, comprising:
- (a) a pair of elongate support members each having a contact surface which can contact a side of the door frame substantially along the length thereof;
- (b) at least one coupling means coupling the support members together so that the support members are movable between a retracted position and an expanded position;
- (c) a fastener means for selectively locking the support members in the expanded position with the contact surfaces contacting the opposed sides of the door frame to brace the sides of the door frame;
- and
- (d) a leg member pivotally connected to each support member for swinging movement laterally to the plane of the door frame, each leg member being adjustable in length to locate the support members at a required inclination with respect to the floor.
The device defined in the 11, wherein the reinforcing member is pivotally connected at a position approximately half way along the length of the one support member.
