The invention provides a
metal section dual glue injection
thermal insulation method and a component, and belongs to the technical field of building sections. The method mainly comprises the following steps that 1), an integral section is firstly prepared, a first section body and a second section body are arranged in parallel and are connected through a connecting rib, a first
thermal insulation glue connecting cavity and a second
thermal insulation glue connecting cavity are arranged on the two sides of the connecting rib respectively, and a first glue injection groove opening and a second glue injection groove opening are formed outside the cavities respectively; 2), thermal insulation glue is injected to the first glue injection groove opening; 3), after glue injection is completed, the connecting rib is
cut out; 4), thermal insulation glue is injected to the second glue injection groove opening, and is connected with the thermal insulation glue of the first thermal insulation glue connecting cavity. The
metal section dual glue injection thermal insulation method has the advantages that product connecting strength is high, the limit that single glue injection cannot reach high connecting strength is removed, the
mechanical property of the section is greatly improved, the thermal insulation need of the section is met, the performance is stable,
processing is convenient, and efficiency is high. The method and the component are especially suitable for section
doors and windows, curtain walls and the like.
