Faciliten enormement l&#8217;acc\u00e9s i sortida de comunitats de ve\u00efns, locals comercials i \u00e0rees industrials. I si alguna cosa ens agrada avui dia \u00e9s la rapidesa.  <\/p>\n<p style=\"text-align: left;\">Per\u00f2 segur que hi ha moltes coses que no sabies sobre les portes autom\u00e0tiques. Per aix\u00f2 desvetllarem <strong>tres curiositats sobre l&#8217;\u00fas, l&#8217;origen i el funcionament dels automatismes per a portes<\/strong> . <\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-7998 size-full\" src=\"https:\/\/medva.es\/wp-content\/uploads\/2020\/09\/puertaautomatica-slider1.jpg\" alt=\"portes autom\u00e0tiques\" width=\"512\" height=\"276\"><\/p>\n<h2 style=\"text-align: left;\">1. El primer referent de porta autom\u00e0tica data del segle I dC<\/h2>\n<p>Encara que pugui semblar que la porta autom\u00e0tica \u00e9s una cosa relativament moderna, podr\u00edem dir que la idea d&#8217;una porta que s&#8217;obr\u00eds sola la van tenir <strong>ja fa m\u00e9s de 2.000 anys<\/strong> . Concretament, <strong>Her\u00f3 d&#8217;Alexandria<\/strong> -un fam\u00f3s inventor- es va proposar crear la primera porta autom\u00e0tica servint-se de la font d&#8217;energia que s&#8217;usava aleshores: el <strong>vapor d&#8217;aigua<\/strong> ! L&#8217;energia obtinguda pel vapor d&#8217;aigua feia funcionar un <strong>enginy\u00f3s sistema de politges i transmissions<\/strong> que aconseguia obrir la porta. Ja <strong>al segle XIX es va estendre l&#8217;\u00fas de l&#8217;energia el\u00e8ctrica<\/strong> . Va ser llavors quan es va perfeccionar el mecanisme de les portes autom\u00e0tiques usant motors el\u00e8ctrics. <\/p>\n<p> <strong>  El 1921 el jove CG Johnson va crear la primera porta autom\u00e0tica ascendent per a garatge.<\/strong><\/p>\n<h2>2. Hi ha portes autom\u00e0tiques \u00abpirates\u00bb<\/h2>\n<p><strong>Hi ha una normativa de compliment obligat per a les portes autom\u00e0tiques<\/strong> . El seu objectiu \u00e9s garantir uns par\u00e0metres b\u00e0sics de seguretat quant al disseny, instal\u00b7laci\u00f3, \u00fas, accessibilitat i protecci\u00f3. Doncs b\u00e9, <strong>al mercat hi ha portes autom\u00e0tiques que no compleixen aquesta normativa<\/strong> per\u00f2 resulten m\u00e9s atractives pel seu preu m\u00e9s redu\u00eft. Tot i aix\u00f2 <strong>han generat greus problemes<\/strong> de seguretat en el seu \u00fas residencial, comercial i industrial. Per aix\u00f2, <strong>el Ministeri d&#8217;Ind\u00fastria, Comer\u00e7 i Turisme ha iniciat una campanya<\/strong> d&#8217;inspeccions per vigilar i sancionar portes autom\u00e0tiques il\u00b7legals per reduir l&#8217;impacte d&#8217;aquestes incid\u00e8ncies i promoure&#8217;n l&#8217;\u00fas responsable.  <\/p>\n<h2>3.
