Therefore, the \"choc\" test is a rapid traction test: the rebar breaks within a few seconds.<\/p>\n<p>The requirement is the rebar breaks, systematically, \u00ab before \u00bb the mechanical coupler\u2026<\/p>\n<p><em>* The thread is rolled following cold-upsetting of the end of the rebar which increases its nominal diameter. The thread rolling maintains the steel integrity of the rebar, which assures an excellent r\u00e9sistance of the splice. The strength of the rebar is therefore not affected by the threading process. H\u00e9risson<sup>\u00ae<\/sup>\u00a0couplers are the only forged couplers,a manufacturing technique preserving the integrity of the steel fibre, which ensures the splice holds under severe constraints.<\/em><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div class=\"wpb_video_widget wpb_content_element vc_clearfix   vc_video-aspect-ratio-169 vc_video-el-width-100 vc_video-align-left\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t\n\t\t\t<div class=\"wpb_video_wrapper\"><iframe loading=\"lazy\" title=\"Le test &quot;choc&quot; du coupleur H\u00e9risson\" width=\"500\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/n2zdBfIgBP4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"The H\u00e9risson\u00ae technical concept (rolled thread after cold-upsetting of the rebar, forged coupler  [...]","protected":false},"author":1,"featured_media":11,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1","post","type-post","status-publish","format-standard","hentry","category-actualites"],"_links":{"self":[{"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/posts\/1","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/comments?post=1"}],"version-history":[{"count":3,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/posts\/1\/revisions"}],"predecessor-version":[{"id":12,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/posts\/1\/revisions\/12"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/media\/11"}],"wp:attachment":[{"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/media?parent=1"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/categories?post=1"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.armaturis.com\/en\/wp-json\/wp\/v2\/tags?post=1"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
