Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to a bridge-type bucket arch tenon structure. Background Art

[0002] The application of aluminum alloy profiles with broken bridge heat insulation in doors and windows has become more and more extensive in recent years. This technology is mainly applied in the design and production of aluminum alloy doors and windows. Through the broken bridge heat insulation design, the heat insulation performance of doors and windows is effectively improved, meeting the requirements of modern buildings for energy conservation, environmental protection and comfort.

[0003] The basic structure of the broken bridge heat insulation aluminum profile is to set a heat insulation strip inside the aluminum profile, disconnecting the inner and outer parts of the aluminum profile to form a broken bridge structure. In this way, the heat transfer between indoors and outdoors is effectively blocked, reducing the heat transfer through the doors and windows, thereby improving the heat insulation performance of the doors and windows.

[0004] After the doors and windows are installed, due to their own weight and other possible external loads (such as wind and rain loads, dynamic loads during use, etc.), the entire frame of the profile supporting the doors and windows will be affected by gravity. Under the action of gravity, the upper side of the cross-section of the entire frame of the profile bears a large pressure, forming a state of eccentric compression, resulting in a low bending resistance of the entire frame of the profile. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a bridge-type bucket arch tenon structure that can relatively stably resist the pressure on the upper side of the left profile and the upper side of the right profile to improve the bending resistance.

The left side of the inner cavity of the left profile is provided with a second strengthening block at a height position in the middle of the two first strengthening blocks, and the second strengthening block is provided with a second arch groove with an opening facing right.

[0007] As an improvement of the above solution, a partition vertical plate is provided in the inner cavity of the left profile, and the partition vertical plate divides the inner cavity of the left profile into a left cavity and a right cavity.

[0009] As an improvement of the above solution, the upper and lower ends of the partition vertical plate are provided with first protruding parts extending rightward, and the left side of the first reinforcing block is provided with second protruding parts extending leftward and arranged in one-to-one correspondence with the first protruding parts.

[0010] As an improvement of the above solution, a connecting strip fixedly connected to the left side of the second reinforcing block is fixedly arranged on the left side of the inner cavity of the left profile.

[0011] As an improvement of the above solution, arc reinforcing parts are arranged at the connection of the connecting strip and the left side of the inner cavity of the left profile and at the connection of the connecting strip and the left side of the second reinforcing block.
