Abstract

The invention discloses a strip-penetrating-method inner cavity polyurethane foam metal sectional bar which solves the problem that the heat insulation property is reduced by air convection. The heat insulation property and the structural strength of the strip-penetrating sectional bar are improved, and the sound insulation effect is improved. The strip-penetrating-method inner cavity polyurethane foam metal sectional bar is composed of a metal sectional bar body A, a metal sectional bar body B, a penetrating strip A, a penetrating strip B and polyurethane foam strips and is characterized in that the metal sectional bar body A and the metal sectional bar body B are respectively provided with a dovetail groove opening, the penetrating strip A and the penetrating strip B are fixed in the dovetail groove opening of the metal sectional bar body A and the dovetail groove opening of the metal sectional bar body B respectively, a cavity is defined after the metal sectional bar body A, the metal sectional bar body B, the penetrating strip A and the penetrating strip B are combined, and the cavity is filled with the polyurethane foam strips. The penetrating strip A and the penetrating strip B are made of plastic, the polyurethane foam strips are formed in a glue injecting mode, polyurethane can be in single component or double components, and holes of the polyurethane foam strips are closed.

Description

technical field [0001] The invention relates to a polyurethane foamed metal profile with an inner cavity by a threading method, which belongs to the field of building door and window materials. Background technique [0002] In order to achieve the purpose of heat insulation, the metal profiles of the heat-insulating doors and windows in the prior art generally adopt the threading method or the glue injection and bridge cutting method to connect the two parts of the metal profile with threading strips (mostly plastic strips) to achieve insulation. heat effect. The strip-threading aluminum profile is to manufacture metal profile A, metal profile B, threading strip A and threading strip B respectively, and then thread threading strip A and threading strip B into the corresponding notches of metal profile A and metal profile B, and roll them The notch outer strip of the aluminum alloy makes the metal profile A, the metal profile B and the threading strip A and the threading str...
