Description

Technical Field

[0001] The utility model relates to a connection and fixing structure for an aluminum alloy door and window, belonging to the technical field of installation of aluminum alloy doors and windows. Background Art

[0002] At present, the window sub-frame of doors and windows is a square frame made of square steel with a width of 4 cm and a thickness of 2 cm. The sub-frame fixes and protects the main frame. It can fill the gap between the door and window profile and the wall, which is conducive to waterproofing and enhances the horizontal and vertical flatness of doors and windows.

[0003] For example, a window steel sub-frame device is disclosed in the patent document with patent publication number 202021879684.4. It includes a window frame sub-frame and a window frame main frame installed on the wall window frame. The window frame sub-frame is located in the inner circle of the wall window frame and has a waterproof gap around it. In the waterproof gap around it, fixed plates for connecting the window frame sub-frame and the wall window frame are arranged at intervals along the length direction. The waterproof gap around it is filled with waterproof mortar embankments along the length direction. The window frame main frame is located in the inner circle of the window frame sub-frame and is close to fit around it. The window frame main frame is fixed to the window frame sub-frame by stainless steel screws around it. This device greatly reduces the probability of water seepage around the window, especially at the window sill, and also improves the annotation and proceduralization of the installation process. The workers' awareness reduces the factors that originally caused water seepage as the process increases. It effectively solves the common quality problem of window water seepage.

[0004] Although the above patent can realize the connection function between the window frame sub-frame and the window frame main frame, the current technical consideration is not comprehensive and has the following disadvantages: the size of the window sub-frame is fixed and cannot be adjusted, and the versatility is poor when used. In addition, the window sub-frame is a fixed structure and cannot be compressed. The installer of the product cannot ensure the fit between the window sub-frame and the main frame of the door and window.

[0005] In order to solve one of the above problems, a connection and fixing structure for aluminum alloy doors and windows is urgently needed. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to change the state of the strip rubber column and then change the overall thickness of the outer frame, the inner frame and the strip rubber column to fill the gap between the main frame of the door and window and the installation wall, and for this purpose, a connection and fixing structure for aluminum alloy doors and windows is provided.

[0007] The connection and fixing structure of aluminum alloy doors and windows described in the utility model is characterized by comprising an outer frame and an inner frame arranged at intervals, a strip rubber column is arranged between the outer frame and the inner frame, the strip rubber column is arranged along the length direction of the outer frame and the inner frame, the outer frame and the inner frame are connected by a frame connecting piece, and the strip rubber column is clamped between the outer frame and the inner frame, and the outer frame is fixed to the installation wall of the window frame or the door frame by a wall connecting piece.

[0008] The present application is a split mechanism, and the outer side surface of the inner frame is the fixing surface of the main frame of the doors and windows. The overall thickness of the outer frame, inner frame and strip rubber columns can be changed by replacing strip rubber columns of different thicknesses to fill the gap between the main frame of the doors and windows and the installation wall.

[0009] Preferably, the strip-shaped rubber column includes a rubber body with a rectangular cross-section, three groups of hollow holes are opened inside the rubber body, and the hollow holes are arranged along the length direction of the second plate body. Two groups of end surface grooves A are symmetrically opened on the abutting surface between the rubber body and the outer frame, and two groups of end surface grooves B are symmetrically opened on the abutting surface between the rubber body and the inner frame.

[0010] The distance between the outer frame and the inner frame is adjusted by the frame connector. The strip rubber column can be compressed as the distance between the outer frame and the inner frame becomes smaller, and return to its original state as the distance becomes larger. The strip rubber column can always fit with the outer frame and the inner frame to ensure the sealing effect. At the same time, the deformation caused by compressing the strip rubber column can change the overall thickness of the outer frame, the inner frame and the strip rubber column to fill the gap between the main frame of the door and window and the installation wall.

[0011] Moreover, during installation, the strip rubber column can be appropriately over-compressed. After the main frames of the doors and windows are installed, some of the compression can be released through the frame connectors to ensure the fit between the inner frame and the main frames of the doors and windows.

[0012] Preferably, the three groups of hollow holes are arranged in equal size, and the centers of the three groups of hollow holes are arranged in an isosceles triangle, which is beneficial to the compression and recovery of the center position of the strip rubber column.

[0013] Preferably, the end surface groove A and the end surface groove B are both arranged along the length direction of the rubber body, and the cross-sections are both V-shaped, which is beneficial to the compression and recovery of the end surface position of the strip rubber column.

[0014] Preferably, the outer frame includes a first plate body, the first side plate and the second side plate are respectively connected to each other vertically on both sides of the back of the first plate body, the rubber body is in contact with the first plate body, and multiple groups of bolt holes are arranged at intervals along the length direction of the first plate body, and the inner frame includes a second plate body, the third side plate and the fourth side plate are respectively connected to each other vertically on both sides of the inner side of the first plate body, and there is a preset gap between the first side plate and the third side plate, and between the second side plate and the fourth side plate, the rubber body is in contact with the first plate body, and multiple groups of internal threaded tubes are arranged at intervals along the length direction of the second plate body, and the multiple groups of internal threaded tubes correspond to the multiple groups of bolt holes one by one. The structure is simple and reasonable, and the connection is reliable.

[0015] Preferably, a plurality of through holes for frame connectors to pass through are arranged at intervals along the length direction of the rubber body. The frame connectors are connecting bolts. Each group of internal threaded tubes corresponds to a group of frame connectors. The rod of the connecting bolt passes through the bolt hole and is threadedly connected to the internal threaded tube.

[0016] A gap is reserved between the frame connector and the wall, and the frame connector can be tightened or loosened as needed. The frame connector cooperates with the internal threaded tube to change the compression amount of the outer frame and the inner frame on the strip rubber column.

[0017] Preferably, the wall connector includes a connecting plate, and the two ends of the connecting plate are respectively vertically connected to an end support plate A and an end support plate B, and the other ends of the end support plate A and the end support plate B are respectively bent outward to form a connecting angle plate A and a connecting angle plate B, and the connecting angle plate A and the connecting angle plate B are fixed to the wall by collision bolts.

[0018] Preferably, the angle between the length direction of the connecting plate and the length direction of the first plate body is set to 15-60 degrees. Avoid interference and facilitate the operation of the frame connector. Preferably, the outer frame, the inner frame and the wall connector are all made of aluminum alloy. Preferably, foam glue is filled between the outer frame and the wall. The final installation of the main frame of the door and window is completed by conventional means.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The connection and fixing structure of the aluminum alloy door and window described in the utility model serves as the window sub-frame of the door and window, and the outer side surface of the inner frame is the fixing surface of the main frame of the door and window. By replacing the strip rubber columns of different thicknesses, the overall thickness of the outer frame, the inner frame and the strip rubber columns can be changed to fill the gap between the main frame of the door and window and the installation wall.

[0021] The connection and fixing structure of the aluminum alloy door and window described in the utility model adjusts the distance between the outer frame and the inner frame through the frame connecting piece. The strip rubber column can be compressed as the distance between the outer frame and the inner frame becomes smaller, and returns to its original state as the distance becomes larger. The strip rubber column can always fit with the outer frame and the inner frame to ensure the sealing effect. At the same time, the deformation caused by compressing the strip rubber column can change the overall thickness of the outer frame, the inner frame and the strip rubber column to fill the gap between the main frame of the door and window and the installation wall.

[0022] The connection and fixing structure of the aluminum alloy doors and windows described in the utility model can appropriately over-compress the strip rubber column during installation. After the main frames of the doors and windows are installed, the excess compression of the strip rubber column is released through the frame connecting parts, thereby increasing the overall thickness of the outer frame, the inner frame, and the strip rubber column, thereby ensuring the fit between the inner frame and the main frame of the doors and windows.
