Description

(54) СПОСОБ ГЕРМЕТИЗАЦИИ СТЫКОВ ПОЛИМЕРНЫХ
ПОКРЫТИЙ
1
Изобретение относитс  к сварке пластмасс , а именно к способам герметизации стыков термопластичных покрытий металлических и железобетонных строительных конструкций методом сварки.
Известен способ герметизации листовых полимерных покрытий, включающий сварку их встык при помощи присадочного материала , и последующее наваривание на это соединение покрывающей полимерной полосы. Перед наваркой покрывающих полос производ т контроль плотности стыковых соединений электроискровым способом 1.
Недостатком этого способа  вл етс  необходимость выполнени  стыкового соединени  покрытий, что при монтаже строительных конструкций с заводским полимерным покрытием практически невозможно. Б св зи с этим таким способом сварки в услови х строительной площадки не пользуютс .
Известен также способ облицовки поверхностей полимерным материалом, при котором соедин емые кромки располагают внахлестку и сваривают между собой гор чей прокаткой 2.
Недостатком способа  вл етс  невозможность применени  дл  контрол  сплошности сварных щвов электроискровой дефектоскопии в св зи с наличием воздушного зазора в нахлесточном соединении между
наружной поверхностью шва и электропровод щей строительной конструкцией. Наличие одностороннего доступа к поверхности сварного соединени  не позвол ет также применить дл  контрол  качества соедине10 НИИ другие известные методы дефектоскопии. Наиболее близким к изобретению по технической сущности и достигаемому результату  вл етс  способ герметизации стыков полимерных покрытий, включающий закрепление на стыке полосы из полимерного ма15 териала и сварку ее с покрытием цри помощи присадочного материала 3.
Недостаток способа заключаетс  в том, что он не позвол ет контролировать герметичность сварных соединений электроискровой дефектоскопией и другими известными методами, что затрудн ет широкое внедрение в строительстве конструкций с заводскими покрыти ми из листовых термопластичных материалов.

  1. Формула изобретения
    Способ герметизации стыков полимерных покрытий, включающий закрепление на стыке полосы из полимерного материала и сварку ее с покрытием при помощи присадочного материала, отличающийся тем, что, с целью обеспечения контроля герметичности сварного соединения, перед сваркой в покрытии по кромкам полосы выполняют сквозные пазы треугольного или трапецеидального сечения, причем поверхность покрытия в зоне паза, прилегающая к кромке полосы, перпендикулярна лицевой поверхности покрытия.
