A flat installed anti cracking floor splice bar with buckle fixation, both the side of the long and short borders of the splice bar plate body (1) have splineway (11), and the other side of the splice bar has rabbet (12), therein, the upper slot surface of splineway (11) is paralleled to the upper surface of the rabbet (12) which are located in the same height. The V type groove (115) and protuberance (123) are mounted in the underside slot surface of splineway (11), furthermore, the frontend of the protuberance (123) is inosculated with the outsaide of the splineway (11) so as to formed the anti selflocking incline which is formed the first angle (.alpha.) with the upper surface of the splice bar, and the rearend of the protuberance (123) is inosculated with the outside of the V type slot (115) so as to formed the selflocking incline which is formed the second angle (.beta.) with the upper surface of the splice bar. The said splice bar can be jointed by putting the rabbet (12) of one splice bar into the splineway (11) of the other splice bar, so the flat installed anti cracking floor with buckle fixation is formed.

L~invention concerne une éclisse pour plancher antifissures monté à plat résistant au flambage. Les côtés des petit et grand bords du corps en plaque (1) de l~éclisse comportent chacun une clavette (11), et l~autre côté de l~éclisse comporte une feuillure (12). La surface de fente supérieure de la clavette (11) est parallèle à la surface supérieure de la feuillure (12) qui est située à même hauteur. La rainure en V (115) et la protubérance (123) sont situées dans la surface de fente de dessous de la clavette (11). L~extrémité avant de la protubérance (123) est reliée au côté extérieur de la clavette (11) de manière à former une inclinaison autobloquante formant un premier angle (.alpha.) par rapport à la surface supérieure de l~éclisse, et l~extrémité arrière de la protubérance (123) est reliée au côté extérieur de la fente en V (115) de manière à former une inclinaison autobloquante formant un deuxième angle (.beta.) par rapport à la surface supérieure de l~éclisse. L~éclisse peut être assemblée en insérant la feuillure (12) d~une éclisse dans la clavette (11) d~une autre éclisse, de façon à former un plancher antifissures monté à plat résistant au flambage.
