Description

Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and particularly relates to an internal and external combined assembly structure of polyurethane rigid foam and aluminum profiles for a PU broken bridge aluminum window. Background Art

[0002] The principle of heat-insulating broken bridge aluminum alloy is to insert a heat-insulating strip into the middle of the aluminum profile to disconnect the aluminum profile to form a broken bridge, effectively preventing the conduction of heat. Compared with ordinary aluminum alloy profile doors and windows, the heat conductivity of broken bridge aluminum windows is sufficiently reduced. The heat-insulating strip is the most critical component of the broken bridge aluminum profile. The traditional material is nylon, while the polyurethane heat-insulating aluminum profile (i.e., PU broken bridge aluminum) is a new type of broken bridge aluminum profile. It changes the traditional broken bridge structure of nylon strip insertion and directly fills the highly heat-insulating and heat-preserving polyurethane into the aluminum profiles by foaming, achieving full-solid heat insulation.

[0003] PU broken bridge aluminum divides the aluminum profile into two parts, the inner side and the outer side, and the two are filled and connected by polyurethane foaming. After the curing process, a solid heat-insulating bridge structure is formed. The polyurethane heat-insulating material can block the heat conduction on both sides of the profile, effectively reducing the heat transfer ability from the high-temperature side to the low-temperature side and achieving excellent heat preservation characteristics. In the prior art, the typical assembly process of PU broken bridge aluminum is as follows: using a special process equipment, fixing the inner and outer sides of the profile in a special mold respectively, then filling with polyurethane foam, and after cooling and curing, forming a solid polyurethane heat-insulating aluminum profile at one time. This assembly structure is relatively cumbersome to operate, and has relatively high requirements for equipment and technology, which is not conducive to fully improving the assembly efficiency. Summary of the Invention

[0004] The utility model aims at the technical defects of the prior art and provides an internal and external combined assembly structure of polyurethane rigid foam and aluminum profiles for a PU broken bridge aluminum window to solve the technical problems of the conventional assembly structure being cumbersome to operate and having low assembly efficiency.
