Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a door and window frame connection structure. Background Art

[0002] The vertical stile is a vertical member in the door and window structure. Its main function is to connect the upper and lower window sashes or door sashes, and provide support and stability. The lower end of the vertical stile is usually connected to the window frame.

[0003] The vertical muntin of the prior art is generally connected to the window frame through a muntin connector. One end of the muntin connector is provided with a slot, which is correspondingly connected to a notch provided on the window frame, and the other end of the muntin connector is inserted into a muntin insertion opening in the vertical muntin. However, the connection method of the vertical muntin and the window frame has high requirements on the installation position of the muntin connector. If the installation position of the muntin connector is biased, the outer side surface of the vertical muntin and the outer side surface of the window frame cannot be aligned, affecting the installation effect. The vertical muntin needs to be removed again to adjust the position of the muntin connector. This method is not convenient for quickly aligning the outer side surface of the vertical muntin and the outer side surface of the window frame. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a door and window frame connection structure.

[0005] The technical solution of this utility model is as follows:

[0006] A door and window frame connection structure, comprising an outdoor window frame and a middle stile vertically connected to the outdoor window frame, wherein the outdoor window frame comprises an outer side plate, a lower side plate, an inner side plate and an upper side plate which are integrally formed, wherein the outer side plate is vertically arranged, perpendicular to the upper side plate and located outside the upper side plate, wherein the outer side plate comprises a hanging wing plate and a side plate body which are integrally formed and arranged up and down, wherein the outer side surface of the hanging wing plate is flush with the outer side surface of the side plate body;

[0007] A support platform extending inward is provided at the upper end of the cantilever plate, and the orthographic projection of the support platform is located within the orthographic projection of the upper side plate. A positioning slot is provided on the upper end surface of the support platform along its length direction. The lower end surface of the middle mullion extends downward to the upper side plate and the positioning slot respectively, and is connected and fixed to the outdoor window frame. The lower end surface of the middle mullion is matched with the positioning slot on one side close to the positioning slot, and the outer side surface of the middle mullion is flush with the outer side surface of the outer plate.

[0008] The lower end surface of the middle mullion can contact the upper side plate and the positioning groove respectively. The upper side plate can increase the contact area between the middle mullion and the outdoor window frame. The positioning groove can directly position the middle mullion on the outdoor window frame so that the outer side surface of the middle mullion is directly aligned with the outer side surface of the outer plate, thereby reducing the alignment operation and improving the installation efficiency of the middle mullion and the outdoor window frame.

[0009] The positioning slot is located on the outer side of the support platform, and the top of the positioning slot and the side close to the outer side of the support platform are both open, so as to facilitate the quick alignment of the outer side of the middle wall and the outer side of the outer plate.

[0010] The specific structure of the above-mentioned positioning slot is that the positioning slot includes a bottom surface and a positioning side surface, the bottom surface is arranged parallel to the upper end surface of the upper side plate, the positioning side surface is located on the inner side of the positioning slot, and the lower end surface of the middle bar is adapted to the bottom surface and the positioning side surface, so that the bottom surface and the positioning side surface are directly in contact with the lower end surface of the middle bar, thereby improving the contact area and the stability of the connection and avoiding sliding and dislocation of the middle bar.

[0011] Regarding the structure of the positioning side, the positioning side is a vertical surface, which is perpendicular to the upper side plate, so as to facilitate the opening of the positioning slot and the installation of the middle wall.

[0012] Another structure of the positioning side is that the positioning side is tilted inward from bottom to top, with an inclination angle of 1-60°, which is convenient for increasing the contact area between the middle wall and the outdoor window frame, facilitating the bonding connection, and improving the stability during the connection.

[0013] Regarding the size of the bottom surface, the width of the bottom surface is 1-5㎜. Within this range, smaller sizes can prevent the middle mullion from being stably overlapped on the outdoor window frame, which is not conducive to the alignment of the outer side of the middle mullion with the outer side of the outdoor window frame.

[0014] In order to improve the stability of the contact surface between the center mullion and the outdoor window frame, the vertical height of the above-mentioned positioning side is 1-3 mm smaller than the bottom width. The outdoor window frame is mainly subjected to the vertical force of the center mullion, and the bottom area is larger than the contact area between the positioning side and the center mullion, thereby improving the supporting effect of the center mullion.

[0015] A corresponding sealing strip mounting platform is provided below the support platform, and a sealing strip is installed between the support platform and the sealing strip mounting platform for sealing the middle stile and the outdoor window frame. The width of the sealing strip is greater than the width of the bottom surface of the positioning card groove. For this purpose, the support platform is arranged to extend inwardly along the width direction of the upper side plate, and the width of the support platform is greater than the width of the bottom surface.

[0016] The beneficial effects of the utility model are:

[0017] The stile is a vertical stile arranged vertically, and its lower end is overlapped on the upper side plate and the positioning slot of the outdoor window frame respectively, and is connected and fixed by bonding or connecting pieces. When the lower end of the stile is installed, it is directly installed in the positioning slot. Since the lower end surface of the stile is adapted to the positioning slot, it is convenient to be connected and installed with the outdoor window frame, and there is no need to install the stile connector and frequently adjust the stile connector to adjust the outer side surface of the stile to be aligned with the outer side surface of the outdoor window frame, thereby reducing the influence of the installation of the stile connector on the structural strength of the outdoor window frame, and improving the installation effect of the window frame;

[0018] The lower end surface of the stile is matched with the bottom surface and the positioning side surface, so that the bottom surface and the positioning side surface directly contact the lower end surface of the stile, thereby improving the contact area and the stability of the connection and avoiding the sliding and dislocation of the stile.

[0026] See also Figure 1 A door and window frame connection structure shown in the figure includes an outdoor window frame 1 and a middle stile 2 vertically connected to the outdoor window frame 1, the outdoor window frame 1 includes an outer panel 11, a lower panel 12, an inner panel 13 and an upper panel 14 which are integrally formed, the outer panel 11 is vertically arranged, perpendicular to the upper panel 14, and located on the outer side of the upper panel 14, the outer panel 11 includes a hanging wing plate 111 and a side panel body 112 which are integrally formed and arranged up and down, the hanging wing plate 111 and the side panel body 112 are located in the same plane, and the outer side surface of the hanging wing plate 111 is flush with the outer side surface of the side panel body 112.

[0027] A support platform 4 extending inward is provided at the upper end of the hanging wing plate 111, and the orthographic projection of the support platform 4 is located within the orthographic projection of the upper side plate 14. A sealing strip mounting platform 5 corresponding to the support platform 4 is provided below the support platform 4. A sealing strip is installed between the support platform 4 and the sealing strip mounting platform 5. One side of the sealing strip is in contact and sealed with the middle stile, and is used to seal and connect the middle stile 2 and the outdoor window frame 1. The width of the sealing strip is greater than the width of the bottom surface 31 of the positioning slot 3. For this purpose, the support platform 4 is arranged to extend inwardly along the width direction of the upper side plate 14, and the width of the support platform 4 is greater than the width of the bottom surface 31.

[0028] See also Figure 2 and Figure 3As shown, a positioning slot 3 is provided on the upper end surface of the support platform 4 along its length direction, and the lower end surface of the middle stile 2 extends downward to the upper side plate 14 and the positioning slot 3 respectively. The surface of the middle stile 2 in contact with the upper end surface of the upper side plate 14 is a first lower end surface 21, the surface of the middle stile 2 in contact with the positioning slot 3 is a second lower end surface 22, and the surface of the middle stile 2 in contact with the support platform 4 is a third lower end surface 23. The lower end surface of the middle stile 2 is connected and fixed to the outdoor window frame 1 by an adhesive or a connector. In this embodiment, an adhesive is used for connection, and there is no need to open holes for installing connectors on the outdoor window frame 1 and the middle stile 2, thereby improving the structural integrity and strength of the middle stile 2 and the outdoor window frame 1. The lower end surface of the middle stile 2 is close to the side of the positioning slot 3 and is adapted to the positioning slot 3, and the outer side surface of the middle stile 2 is flush with the outer side surface of the outer plate 11.

[0029] The lower end surface of the middle mullion 2 can contact the upper side plate 14 and the positioning slot 3 respectively. The upper side plate 14 can increase the contact area between the middle mullion 2 and the outdoor window frame 1. The positioning slot 3 can directly position the middle mullion 2 on the outdoor window frame 1, so that the outer side surface of the middle mullion 2 is directly aligned with the outer side surface of the outer plate 11, reducing the alignment operation and improving the installation efficiency of the middle mullion 2 and the outdoor window frame 1.

[0030] The specific structure of the positioning slot 3 is that the positioning slot 3 is located on the outer side of the support platform 4, and the upper side of the positioning slot 3 and the side close to the outer side of the support platform 4 are both open, so as to facilitate the quick alignment of the outer side of the middle stile 2 with the outer side of the outer plate 11. The positioning slot 3 includes a bottom surface 31 and a positioning side surface 32, the bottom surface 31 is arranged parallel to the upper end surface of the upper side plate 14, and the positioning side surface 32 is located on the inner side of the positioning slot 3. The lower end surface of the middle stile 2 is matched with the bottom surface 31 and the positioning side surface 32, so that the bottom surface 31 and the positioning side surface 32 are directly in contact with the lower end surface of the middle stile 2, thereby increasing the contact area and the stability of the connection, and avoiding the sliding and dislocation of the middle stile 2.

[0031] See also Figure 2 As shown, one arrangement of the positioning side surface 32 is that the positioning side surface 32 is a vertical surface, which is arranged perpendicularly to the upper side plate 14 , so as to facilitate the opening of the positioning slot 3 and the installation of the middle bar 2 .

[0032] See also Figure 4 As shown, another arrangement of the positioning side surface 32 is that the positioning side surface 32 is inclined inward from bottom to top, and the inclination angle is 1-60°, which is convenient for increasing the contact area between the middle stile 2 and the outdoor window frame 1, which is conducive to the adhesive connection and improves the stability during the connection. The arrangement of the positioning side surface 32 mentioned above, this embodiment adopts the first arrangement, which is convenient for the opening of the positioning slot and reduces the manufacturing cost.

[0033] Regarding the size of the bottom surface 31, the width of the bottom surface 31 is 1-5 mm. Within this range, a smaller size can prevent the middle stile 2 from being stably overlapped on the outdoor window frame 1, which is not conducive to the alignment of the outer side of the middle stile 2 with the outer side of the outdoor window frame 1. If the width of the bottom surface 31 is larger, the area occupied by the positioning slot 3 increases, so that the width of the support platform 4 also needs to be set larger. The support platform 4 is suspended on the hanging wing plate 111, and will bend downward under the gravity of the middle stile 2. In order to improve the stability of the contact surface between the middle stile 2 and the outdoor window frame 1, the vertical heights of the above two positioning side surfaces 32 are both smaller than the width of the bottom surface 31 by 1-3 mm. The outdoor window frame 1 is mainly subjected to the vertical force of the middle stile 2. The area of ​​the bottom surface 31 is larger than the contact area between the positioning side surface 32 and the middle stile 2, which improves the supporting effect of the middle stile 2.
