With the continuous improvement of technology, the performance of the window frame has been more perfect, and the heat insulation effect of the building has also been further improved. A horizontal or vertical division of the window splicing frame is called a mullion, and the mullion can enhance the stability of the window frame.

[0003] A related technology (publication number: CN213063302U) discloses a window frame installed with a high-stability mullion. The disclosed technical solution: the steel liner is fixed by using positioning bolts, which improves the aesthetic degree of the window frame.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Next, in combination with specific implementation cases and attached Figures 1 - 7 The present invention will be further described, but the present invention is not limited to these embodiments.

[0034] A window frame structure configured with a high-strength middle mullion includes an inner middle mullion 1 for dividing the inner window type. The inner middle mullion 1 is an integrally formed structure, which plays a role in dividing the inner window type and ensures the strength of the inner side of the window frame. On the side of the inner middle mullion 1 facing the outdoors, there is an outer middle mullion 2 for dividing the outer window type, and the inner middle mullion 1 and the outer middle mullion 2 are connected by a thermal insulation and heat insulation broken bridge 3. The thermal insulation and heat insulation broken bridge 3 is installed between the inner middle mullion 1 and the outer middle mullion 2, and has a heat insulation effect on the inside and outside through the thermal insulation and heat insulation broken bridge 3. The thermal insulation and heat insulation broken bridge 3 includes two groups of spliced heat insulation strips, and the internal heat insulation strip divides the thermal insulation and heat insulation broken bridge 3 into three hollow heat insulation cavities. Through the three hollow heat insulation cavities, a layered heat insulation effect is achieved inside the thermal insulation and heat insulation broken bridge 3, reducing the thermal conductivity between the inner frame body 1 and the outer frame body 2, thereby ensuring the indoor temperature.

[0035] The outer middle mullion 2 is an integrally formed structure. Both sides of the integrally formed outer middle mullion 2 are set as double-arm structures, so as to divide the outer window type, and further ensure the overall stability of the window frame. An integrally formed corner code 17 is embedded in the inner cavity of the outer middle mullion 2, and an integrally formed corner piece is provided on the side wall of the outer middle mullion 2. Through the corner code 17 and the corner piece integrally formed with the outer middle mullion 2, the processing of the window frame is more convenient. When installing the corner code 17 and the corner piece, there is no need to trim according to the shape of the window frame, thus avoiding waste of materials. The corner code 17 and the corner piece integrally formed with the outer middle mullion 2 ensure the strength of the outer middle mullion 2, and further ensure the overall stability of the window frame.

[0036] Anti-gap sealing components are arranged on both sides of the thermal insulation broken bridge 3. The thermal insulation broken bridge 3 improves the sealing of the glass after installation, avoids cold bridges between the glass gaps, and prevents air leakage between the glass gaps, thereby ensuring the stability of the indoor temperature.

[0037] The sealing assembly includes a glass windproof pad 9 arranged on the side facing the glass, and the glass windproof pad 9 is arranged on one side of the thermal insulation bridge 3 through an assembly part, and the other side of the thermal insulation bridge 3 is provided with a double-glue sealing strip 5 through an assembly part. The double-glue sealing strip 5 is composed of a PVC strip and a nylon strip, and the double-glue sealing strip 5 ensures the sealing after the window is closed.

[0038] The glass windproof pad 9 is used to prevent cold bridges and air leakage after the glass is installed. The double-glue sealing strip 5 and the glass windproof pad 9 enhance the sealing between the glass and the window frame, thereby ensuring the stability of the indoor temperature.

[0039] It is worth noting that the assembly parts include pre-installed card blocks 24 arranged on the side walls of the glass windproof pad 9 and the double-glue sealing strip 5, and pre-installed card slots 25 corresponding to the pre-installed card blocks 24 are arranged on both sides of the thermal insulation bridge 3.

[0040] When the glass windproof pad 9 and the double-glue sealing strip 5 are respectively assembled to the two sides of the thermal insulation bridge 3, they are first engaged with the pre-installed card block 24 and the pre-installed card slot 25, and then fixed to avoid assembly errors, thereby ensuring the quality of the window frame.

[0041] In addition, a glass buckle strip 4 is provided on the side wall of the inner muntin 1, and the glass buckle strip 4 is buckled with the inner muntin 1 through a buckle strip buffer rod 10. After the glass is installed on the inner muntin 1, the glass buckle strip 4 is rotated and buckled to the outer side of the glass through the buckle strip buffer rod 10, making the operation of the glass installation process more convenient, thereby ensuring the stability of the glass after installation.

[0042] In addition, an indoor inner glass adhesive strip 12 is provided between the glass buckle strip 4 and the contact surface of the glass. Before the glass buckle strip 4 is buckled on the glass surface, the indoor inner glass adhesive strip 12 is installed on the glass. The indoor inner glass adhesive strip 12 has a buffering effect on the glass during installation, preventing the glass from self-explosion, thereby ensuring the tightness of the glass buckle strip 4.

[0043] Furthermore, an outdoor stopper strip 11 is provided on the side of the inner stile 1 close to the window sash. The outdoor stopper strip 11 is installed at the joint between the window frame of the open window and the inner stile 1, and the outdoor stopper strip 11 ensures the sealing of the window after closing. The outdoor stopper strip 11 reduces the K value, that is, reduces the heat transfer coefficient of the window frame, thereby achieving a heat preservation effect.

[0044] Outdoor side glass outer rubber strips 8 are provided on both sides of the outer middle mullion 2. After the window is closed, they play a sealing role to prevent rainwater from pouring in and also play a buffering role when installing the glass through the outdoor side glass outer rubber strips 8.

[0045] Pre-installed sliders 6 are symmetrically arranged on one side of the heat insulation and sound insulation broken bridge 3 relative to the outer middle mullion 2, and pre-installed sliding grooves 7 are symmetrically opened on one side of the outer middle mullion 2 relative to the heat insulation and sound insulation broken bridge 3. When installing the outer middle mullion 2, the outer middle mullion 2 is sleeved outside the pre-installed sliders 6 through the pre-installed sliding grooves 7, so as to pre-install the outer middle mullion 2 on the heat insulation and sound insulation broken bridge 3.

[0046] A reverse stop member 15 is penetrated through the inner wall of the pre-installed sliding groove 7, and the reverse stop member 15 is arranged on the inner wall of the pre-installed sliding groove 7 through a rebound assembly. Reverse stop grooves 13 are evenly arranged on the side wall of the pre-installed slider 6 relative to the outer middle mullion 2, and a limit bottom plate 18 is arranged at the adjacent edge of the bottom of the pre-installed sliding groove 7.

[0047] When installing the outer middle mullion 2, the reverse stop member 15 is made to slide through the reverse stop grooves 13 in sequence through the rebound assembly. When the bottom of the pre-installed slider 6 moves to the limit bottom plate 18 at the bottom of the pre-installed sliding groove 7, at this time the reverse stop member 15 is clamped in the reverse stop groove 13, thus ensuring the stability of the position where the outer middle mullion 2 is located. Then the outer middle mullion 2 is fixed, and further ensuring the sealing performance after the outer middle mullion 2 is installed.

[0048] The rebound assembly includes bases 19 that are evenly and fixedly installed on the inner wall of the outer middle mullion 2. Four parallel fixing rods 23 are vertically and symmetrically and fixedly installed on the inner wall of the outer middle mullion 2. The other ends of the four fixing rods 23 are vertically fixed on the surface of the base 19, so as to fix the base 19 in a position parallel to the outer middle mullion 2.

[0049] A locking rod 21 is penetrated through the inner cavity of the base 19. One end of the locking rod 21 is fixedly installed on the side wall of the reverse stop member 15. The locking rod 21 penetrates through the base 19, and the locking rod 21 slides in the through hole of the base 19. The other end of the locking rod 21 is fixedly installed on the side wall of the anti-detachment block 20. An elastic member 22 is sleeved outside the locking rod 21. The elastic member 22 can be a compression spring. The elastic member 22 is movably sleeved outside the locking rod 21, so that the elastic member 22 fits on the outer wall of the locking rod 21 and slides telescopically.

[0050] A through groove 16 extending to the inner cavity of the outer middle mullion 2 is opened on the inner wall of the pre-installed sliding groove 7, and the through groove 16 corresponds to the reverse stop member 15, so that the reverse stop member 15 fits and slides on the inner wall of the through groove 16. The reverse stop member 15 is wedge-shaped, and the inclined surface of the reverse stop member 15 corresponds to the inclined surface of the reverse stop groove 13, ensuring that the reverse stop member 15 slides through the inclined surface of the reverse stop groove 13 in sequence, so that the outer middle mullion 2 will not move reversely during the installation process, thus ensuring the sealing and stability of the installation of the outer middle mullion 2.
