Novel building window frame and mounting method thereof

Abstract

The invention discloses a novel building window frame and a mounting method thereof. The novel building window frame comprises a main body structure, a window frame body, screws, a foaming agent, an indoor sealant and an outdoor sealant, and a hole of the main body structure is of a notch type structure. The window frame body is attached to and extends into the notch until a certain gap is reserved between the window frame body and the main body structure, and the screws are arranged at the window frame body in a penetrating mode to be in threaded connection with the main body structure. The gap between the window frame body and the main body structure is filled with the foaming agent, the boundary position of one side of the window frame body and the main body structure is coated with theindoor sealant for sealing, and a boundary position of the other side of the window frame, the foaming agent and the main body structure is coated with the outdoor sealant for sealing. According to the novel building window frame and the mounting method thereof, the space between an aluminum frame and a wall body is filled with a foaming agent soft heat preservation material, and the aluminum frame does not make contact with cement and is in flexible connection with the cement.

Description

technical field [0001] The invention relates to the field of building door and window installation engineering, in particular to a novel building window frame and an installation method thereof. Background technique [0002] At present, the methods of installing doors and windows include dry installation and wet installation. In the wet method, cement mortar is poured between the aluminum frame and the wall to fill the gap. The wet method has the following major disadvantages: (1) wet cement mortar will corrode the aluminum; (2) when the aluminum frame is small in section and the material is thin, the cement mortar caulking will easily lead to deformation of the aluminum frame; (3) The thermal expansion coefficients of cement and aluminum frames are different, and the thermal stress generated cannot be eliminated and can only be absorbed by the deformation of the aluminum frame. After a certain period of time, the cement will crack and water seepage is prone to occur; (4) T...

The wet method has the following major disadvantages: (1) wet cement mortar will corrode the aluminum; (2) when the aluminum frame is small in section and the material is thin, the cement mortar caulking will easily lead to deformation of the aluminum frame; (3) The thermal expansion coefficients of cement and aluminum frames are different, and the thermal stress generated cannot be eliminated and can only be absorbed by the deformation of the aluminum frame. After a certain period of time, the cement will crack and water seepage is prone to occur; (4) The main structure will subside, and the cement mortar will The settlement of the joint filling must be absorbed by the deformation of the aluminum frame; (5) During the earthquake, the cement mortar joint filling makes the whole window lose its plane deformation ability; (6) There is a hidden danger of water seepage in the cement mortar joint joint
