METAL FRAME OF PANEL FORMS AND ROLL-FORMED SECTIONS Russian patent published in 2009 - IPC E04G9/06 

FIELD: construction.

SUBSTANCE: present invention pertains to construction and can be used for monolithic construction of buildings. The metal frame of panel forms and roll-formed sections, which is part of the framework, is used when assembling forms during construction of buildings. The metal frame of panel forms has a frame, rigidly fixed by reinforcement plates. The frame is made from a roll-formed section, with a main corrugation in the middle of the roll-formed section, and with side walls and a base. The roll-formed section also has two shelves, whose bases are mated with the side walls of the main corrugation. An extra corrugation is made at the base of the main corrugation and is oppositely directed to the latter. The shelves of the roll-formed section have three parts. The first parts face the opposite direction of the main corrugation, the second parts are mated through the third parts of the shelves with the first parts and their free ends are in contact with the outer surfaces of the side walls of the main corrugation, forming closed volumes. The outer surfaces of the second parts of the shelves and the outer surfaces of the base of the main corrugation are mated on one side with the extra corrugation, and on the other side with the side walls of the main corrugation. The outer surfaces of the second parts of the shelves and the outer surfaces of the base are flat and lie in the same plane.

EFFECT: increased rigidness, longevity and reliability of forms with a frame of roll-formed section under dynamic loads.
