Description of the invention (5) According to another characteristic aspect of the present invention, one of the pair of opposed flanges, for example, the flange 16 in FIG. 2 has a lower stiffness than the interlocking flange 14. This item is achieved by reducing the surface area, or reducing the width of the inwardly oriented portion 24 of the lower stiffness flange 16 relative to the width of the other flange 14 in this example. As such, the lower stiffness flange 16 tends to deflect or rotate outward before the flange 14 is interlocked. The lower stiffness flange 16 may not be counted as having a stiffness approximately equal to the stiffness of the flange 14. This reduction in stiffness is achieved by comparing the corresponding portion of the other flange with the lower stiffness flange to reduce the surface area of the flange above the rib. In operation, a concrete load inside a metal recessed plate element such as 18 forces a lower stiffness flange 16 to interlock with the flange 14 adjacent to the recessed plate element 10. The adjacent metal recessed elements 10 and 18 are thus "knotted" without the need for cumbersome fasteners. Although not shown in the drawings, the inwardly oriented portions 22 and 24 may include openings to allow air to be ventilated by the flanges when the concrete is poured into the metal concave plate. Otherwise, the air is trapped as an air bag, and is particularly trapped in the area surrounded by the return flanges 26 and 28 of the inwardly oriented portions 22 and 24 to form an air bag. The openings are formed by a plurality of longitudinally extending slits in the inwardly oriented portions 22 and 24, and the inwardly oriented portions are pressed upward to leave the respective flange planes. In a specific embodiment, the slits are formed to have a horizontal interval of about 8 mm for each of them; adjacent inwardly oriented portions such as 22 are pressed away from the respective flange planes by about 3 mm. The slits formed by the flanges also promote the joining of the concrete to the recessed plate elements. Fig. 3 illustrates another specific embodiment of the present invention. Here, the sheet 16 of the metal concave plate element 12 is arched inwardly and forwardly from the longitudinal direction of the metal concave plate element 12. For clarity, the metal concave plate element shown does not include the longitudinal orientation. The paper size applies the Chinese National Standard (Norway) A4 specification (21〇 > < 297mm) Φ (Please read the precautions on the back before filling this page ) _, May, five, description of the invention (6) ribs. Metal recesses embedded in concrete slabs (not shown in the figure) can span a long, unsupported distance. The piece 16 is placed before the chess piece to start The maximum value of the longitudinal deviation of the material from the rough flat surface is measured 'and expressed as a percentage relative to the length of 16 is about G.6%. It is necessary to understand that the longitudinal front of the material 16 is at least partially under the weight of the visible concrete slab This longitudinal front arching provides a good deflection towards the flat surface. The metal concave plate element has a large distance with a minimum deflection. In this specific embodiment, the metal concave plate element supports a span of up to about 5 meters. Approximately 06% of the longitudinal front chess is about 30 mm. The unsupported span 5 of the specific embodiment of the present invention can be at most as long as the conventional concave board without the longitudinal front arch 3 meters for comparison. Although not clearly shown 'but metal concave plate element 2 The material piece M can also be arched in front at the side edge of the cross section. In this example, the material piece is measured by the maximum deviation of the material piece 16 from the substantially flat plane and measured relative to the width of the material piece 16 It is expressed as approx. In this example, the width of the metal concave plate element 12 is about 300 mm, and the shape is formed by a plate-shaped metal plate with a thickness of about 12 mm. The web I6 is formed. The corrugated wipes (not shown) are oriented horizontally and extend across a portion of the width of the web 16. The transverse corrugations are cold-rolled on the sheet 16, and the transverse corrugations are "shallow" enough to provide a longitudinal front arch which is preferably at most about 2%. The corrugations are formed on the flat strips or the M-shaped cross-section side material on the web 16. Otherwise, the corrugations of the web 16 are formed by corrugating rolling (not shown) in a conventional cold rolling method. ^ 1588 V. Description of the invention (Please read the notes on the back before filling out this page.) Hot technologists understand that the invention described herein is sensitive to changes and modifications other than those specifically described here. For example, the configuration of the longitudinal rib of the facing flange can be changed, as long as it allows the adjacent concave plate elements to interlock. The lower-stiffness flange can be changed by the configuration as long as this adjacent flange of the adjacent concave plate element is provided to interlock. The preferred blanks are recessed plate elements which are arched inwardly in the longitudinal and / or transverse direction, whereby the distance from the unsupported compilation is longer. All such particularities and modifications are considered to be within the scope of the invention as determined by the foregoing description. In the foregoing summary of the invention, unless there is a different requirement due to expression language or suggestion, the word "include" is used as the meaning of "including", in other words, this particular feature may be related to other features of the specific embodiments of the present invention.
