Description

Technical Field

[0001] This utility model relates to the field of door and window subframes, specifically a structure for a door and window subframe. Background Technology

[0002] The subframe for doors and windows is installed inside the door and window opening to fix the door and window frame on the inside, providing support and enclosure. It is crucial for achieving millimeter-level precision in door and window dimensions. Currently, when fixing prefabricated door and window frames with fixed glass to the subframe, the door and window frame must first be connected to the subframe using fasteners before the fixed glass is installed. This makes it impossible to quickly assemble or replace prefabricated door and window frames with fixed glass. With the increasing market demand for factory-produced prefabricated doors and windows and prefabricated buildings, there is an urgent need for a subframe structure that allows for simple, quick, and convenient installation or replacement of door and window frames.

[0003] A Chinese invention patent with publication number CN221220177U discloses a door and window subframe structure, which includes a window sash and a subframe assembly connected to the window sash. The subframe assembly includes a fixing member and a frame body. The fixing member is located on the indoor side of the frame body and is detachably connected to it. An installation space for accommodating the window sash is formed between the fixing member and the frame body. The frame body is fixedly connected to the wall. The window sash and the frame body form a cavity. A drainage hole is provided on the outdoor side of the frame body. The drainage hole communicates with the cavity. It has the characteristics of simple structure, convenient disassembly and assembly, and concealed drainage.

[0004] The aforementioned door and window subframe structure has a limiting part on the outdoor side, which makes it easy for the door and window frames to collide when being hoisted from the outdoor side into the room. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for a door and window subframe that allows for the disassembly of the side guards located on the indoor and outdoor sides during the installation or replacement of door and window frames. This enables the door and window frames to be quickly hoisted into the room without the need for screwing the subframe to the door and window frame. The door and window frames can be quickly fixed by directly installing the side guards on both sides, thus solving the problems of the prior art. This is a structure for a door and window subframe that allows for simple, fast, and convenient installation or replacement of door and window frames.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a door and window subframe structure for fixing to the center side of a door and window opening, and fixing a door and window frame to the center side of the structure, characterized in that: it includes a door and window subframe frame that matches the shape of the door and window opening, the door and window subframe frame includes a main body, the main body is a frame composed of subframe profiles connected together, the main body is connected to the door and window opening, the connection method is concrete pre-embedding or connecting piece connection, the subframe profile is a long straight profile with a central protrusion, the central protrusion of the main body faces the center side of the door and window subframe frame, forming a boss surrounding the four sides of the door and window frame, the boss has an inner side guard structure and an outer side guard structure respectively installed on the main body, the outer side guard structure has a platform with a height similar to the boss, the four sides of the door and window frame are built into the boss and the platform, the inner side guard structure and the outer side guard structure respectively block and abut against the indoor and outdoor sides of the door and window frame.

[0007] Preferably, the subframe profile is a steel bent open profile.

[0008] Preferably, the inner edge structure abuts the interior side of the door and window frame, including an inner edge strip that surrounds the interior side of the door and window frame. The inner edge strip is a long straight profile, and the main body is connected to the inner edge strip by a connector.

[0009] Preferably, a pad is provided at the gap between the inner side retaining structure and the contact surface of the door and window frame.

[0010] Preferably, the first connector is snapped into the inner side guard strip, and the first connector is screwed into the main body.

[0011] Preferably, the outer edge structure abuts the outdoor side of the door and window frame, including an outer edge strip that surrounds the outdoor side of the door and window frame. The outer edge strip is a long straight profile, and the main body is connected to the outer edge strip by a connector.

[0012] Preferably, a pad is provided at the gap between the outer edge structure and the contact surface of the door / window frame.

[0013] Preferably, the second connector is snapped into the outer edge strip, and the second connector is screwed into the main body.

[0014] Preferably, the outer edge strip has drainage holes for draining rainwater.

[0015] Preferably, a pad block is provided at the gap between the door / window subframe and the door / window frame.

[0016] Compared with the prior art, the advantages of this utility model are: when installing or replacing door and window frames, the door and window frames can be quickly hoisted from the outside to the interior, and the prefabricated door and window frames with fixed glass can be directly and quickly installed or replaced without screwing the subframe to the door and window frame.
