Abstract: 1. Panel concrete form frame made of an aluminum alloy and comprising three flat elements two of which are parallel to each other and perpendicular to the third element, characterized in that said two former parallel elements have equal length, the cross section of the frame is rectangular in shape, three sides of said rectangle being formed by said three elements, one longer side of said rectangle that connects said two parallel equal-length sides has a cavity in the form of a right angle with equal perpendicular sides, this cavity being shifted from the middle of said longer side towards a shorter rectangle side and oriented towards the other longer side of the frame, the second longer side of said frame has a slotted recess on its outer side, the length of which slotted recess is not larger than the length of the longer inner side of the frame, and the same longer side of said frame has an flange oriented along said longer side, the thickness of said flange being equal to the thickness of the elongated side said flange is located on. 2. Element according to claim 1, characterized in that the length of said flange is 20+-1.00 mm, the length of the longer side is 120+-1.1 mm, the length of the shorter side is 60+-0.8 mm, the length of the slotted recess is 95+-9.5 mm, the depth of the slotted recess is 1.5+-0.15mm, and the end of the slotted recess is 30+-3 mm away from the distant end of the flange. 3. Element according to claim 1, characterized in that the thickness of said flange and the thickness of the elongated side that carries this flange is 60.5+-0.35 mm, the thickness of other elements of the frame being 5+-0.35 mm. 4. Concrete form panel with a framework of flat frames, characterized in that said framework is made of first type frames and at least three second type frames are placed between two parallel first type frames, the first type frame being made of an aluminum alloy and comprising three flat elements two of which are parallel to each other and perpendicular to the third element, said two former parallel elements have equal length, the cross-section of the first type frame is rectangular in shape, three sides of said rectangle being formed by said three elements, one longer side of said rectangle that connects said two parallel equal-length sides has a cavity in the form of a right angle with equal perpendicular sides, this cavity being shifted from the middle of said longer side towards a shorter rectangle side and oriented towards the other longer side of the frame, the second longer side of said frame has a slotted recess on its outer side, the length of which slotted recess is not larger than the length of the longer inner side of the frame, and the same longer side of said frame has an flange oriented along said longer side, the thickness of said flange being equal to the thickness of the elongated side said flange is located on, the first type frames being positioned such that said flange is on the outer side of the framework, the second type frame is also made of the aluminum alloy and its cross-section is H-shaped, the edges of one of its parallel elements have first supports that are parallel to the element that connects said parallel elements of said H-shaped frame, and the edges of the other of its parallel elements have second supports that are parallel to said first supports and oriented in the same direction, the ends of said second supports are twice bent at right angles in the opposite direction such that the end faces of said second supports are oriented towards the ends of said first supports, the height of said end faces of said second supports is equal to the height of said first supports, and the width of the second one of the parallel elements in the H-structure of the frame is 35-45 mm and is equal to the length of the second supports to the first right angle bent. 5. Panel according to claim 4, characterized in that said panel is rectangular in shape. 6. Panel according to claim 4, characterized in that said second type frames are parallel one to another and at equal distances between them. 7. Panel according to claim 4, characterized in that said first and second type frames are weld-joined. 8. Panel according to claim 4, characterized in that for said first type frame the length of the flange is 20+-1.00 mm, the length of the longer side is 120 +-1.1 mm, the length of the shorter side is 60 0.8 mm, the length of the slotted recess is 95+-9.5 mm, the depth of the slotted recess is 1.5+-0.15 mm, and the end of the slotted recess is 30+-3 mm away from the distant end of the flange. 9. Panel according to claim 4, characterized in that for said first type frame the thickness of said flange and the thickness of the elongated side that carries this flange is 60.5+-0.35 mm, the thickness of other elements of the frame being 5+-0.35 mm. 10. Panel according to claim 4, characterized in that for second type frame the parallel elements are 90-110 mm in length. 11. Panel according to claim 4, characterized in that for second type frame the first supports are 10-20 mm in height. 12. Panel according to claim 4, characterized in that it is made of any material not adhesive to concrete. 13. Panel according to claim 4, characterized in that between said parallel end elements of the second type frame and parallel to the to said first type frames, third type frames with a rectangular cross-section are installed. 14. Panel according to claim 13, characterized in that between said third type frames and said first type frames adjacent thereto, at least two elements made of said third type frames are installed perpendicular to said first and second type frames. 15. Panel according to claim 13, characterized in that third type frames are parallel to first and second type frames. 16. Panel according to claim 13, characterized in that at least two of the angles formed by said first type frames are equipped with a joining element made of said third type frames and attached to said first type frames. 17. Panel according to claim 16, characterized in that the two angles formed by first type frames are diagonally positioned across the panel.
