Description

Technical Field

[0001] The utility model relates to the technical field of door and window structure assembly, in particular to a 45-degree angle assembly structure of a central sash of a high-air-tightness sliding window. Background Art

[0002] Doors and windows in the building environment will be subject to various forces such as opening impact, wind pressure, temperature change stress, etc., which will lead to insufficient strength of the connection angle of the door and window frame, corner cracks, connection deformation, loss of the basic frame retention ability of the door and window, and leakage of the door and window, and failure to open normally, which seriously affects the sealing and safe use of the door and window. This shows the importance of the door and window corner assembly process to doors and windows. The door and window corner assembly process is also called the corner connection process. A complete door and window needs to be spliced ​​by frame and leaf structure profiles, and the key to the connection between profiles lies in the splicing of the corners, that is, the two profiles are connected and fixed together at an angle of 90° or 45° in a certain way. The 90° angle assembly is generally connected by screws or angle codes. Screw connections are usually loose and not firm, and the strength is relatively low. The angle code connection is fixed with pins, which is prone to tilting of the vertical frame and the horizontal frame. The angle strength will be affected by various environments, and there will be looseness and air leakage. Generally, the side sash frames of a sliding window are at a 45° angle to the upper and lower sash frames, but the middle sash frame (the opposite frame of the side sash frames) is at a 90° angle to the upper and lower sash frames. Therefore, the angle position of the middle sash frame of the inner and outer sashes of the sliding window has a great influence on the air tightness and wind pressure resistance of the entire sliding window.

[0003] In the prior art, a connection structure for sliding door and window sashes disclosed in a Chinese utility model patent with announcement number CN211342531U and application date 2019-10-18 includes a horizontal sash material and a vertical sash material; the horizontal sash material has a first side and a second side opposite to each other, one of which is provided with a limit groove matched with a slide rail, and the other of which is provided with a fixing groove for installing a base plate; the vertical sash material is provided with a notch for fixing the base plate, the notch extends in the vertical direction, and a connector with a transverse protruding section is provided in the notch, and the connector can move up and down in the notch; the end of the horizontal sash material is provided with a cavity adapted to the transverse protruding section; the vertical sash material is also provided with a reinforcement member, which is connected to the vertical sash material and the horizontal sash material respectively. Although the patent can be inserted into the cavity through the transverse protruding section, the contact area between the horizontal sash material and the vertical sash material is increased to achieve the connection between the two. The setting of the reinforcement member can ensure the reliability of the relative position between the horizontal sash material and the vertical sash material, thereby enhancing the anti-vibration and anti-impact capabilities of the sliding door and window sash. However, the window frame is connected to the horizontal sash material and the vertical sash material by screws, and the screw connection is usually loose and not firm, with relatively low strength, and the vertical frame and the horizontal frame are tilted.

[0004] For this purpose, a 45° angle structure for the middle sash of a high-air-tightness sliding window is proposed to improve the air-tightness and wind pressure resistance of the sliding window. Utility Model Content

The end face glue is first applied to the surface of the aluminum alloy profile joint, and then the fixed angle code and the angle steel sheet are inserted into the 45° inclined surface of the upper sash frame or the middle sash frame. Finally, the upper sash frame and the middle sash frame are connected and formed into one piece through precision machine collision and extrusion, and holes are punched and glue is injected on the profile. The advantage of this process is that it has seamless connection and good sealing, and it is not easy to get water in and crack, and its corner strength is high. Therefore, the 45° angle assembly is stronger than the 90° angle assembly, with better sealing performance and stronger wind pressure resistance. Then install the sliding cover base and the sash corner plugging end cover on the middle sash frame. At this time, the sides of the middle sash frame are all on the same plane. Finally, install the sliding sash cover to complete the installation of the middle sash frame and the upper sash frame.

The profile wall is pressed into the groove of the angle code by the impact and extrusion of the mechanical angle assembly machine. The angle assembly steel sheet will undergo a certain deformation and be tightly connected with the upper sash frame 1 and the middle sash frame 3, so as to achieve the tight connection of the fixed angle code with the upper sash frame 1 and the middle sash frame 3 profiles, and obvious mechanical indentations will be left on the profile surface. The strength of the 45° angle assembly structure of the middle sash of the sliding window is guaranteed, the stability of the basic frame of the sliding window is increased, and the sliding window can cope with various impact forces such as man-made, strong winds, and temperature changes.

[0033] Preferably 2, such as Figure 2 As shown, the gap is formed by the 45° angle between the upper sash frame and the middle sash frame. The sliding cover base 5 is pushed into the profile structure of the middle sash frame 3 and fixed together with it. The upper sash frame 1, the middle sash frame 3, and the sliding cover base 5 will form a triangular gap, and then the sash corner plugging end cap 4 is inserted into the triangular gap, and then the sliding window sash cover 6 is snapped into the sliding cover base 5.

[0034] Preferably 3, such as Figure 2 As shown, one side of the angle steel sheet 2 of the upper sash frame 1 and the middle sash frame 3 is the outdoor side, and the side of the sash angle sealing end cover 4 is the indoor side.
