Detailed Description

Fig. 1 is an exploded perspective view of a window and door frame 10 according to a first embodiment of the present invention. Fig. 2 is another exploded perspective view of the window and door frame according to the first embodiment of the present invention, in which the window and door frame is assembled after the fastening member 14 is installed. In the first embodiment, the window and door frame 10 is configured as a rectangular window frame.

The window and door frame 10 includes a first frame 11 and second and

third frames

12 and 13 received in the first frame 11. The first frame 11 may comprise four

sheets

11a, 11b, 11c, 11d, which may be adjacent on each two adjacent ends, in particular interconnected, for example by wood screws. Each

sheet

11a, 11b, 11c, 11d of the first frame 11 may have a gore, for example, a 45 ° gore, on two opposite ends. A sealant may be additionally applied to the joints of the respective panels of the first frame 11.

The second frame 12 may be formed of a fiber cement board. The second frame 12 may comprise four

sheets

12a, 12b, 12c, 12d, each of which may be formed from a sheet of fiber cement. The

respective sheets

12a, 12b, 12c, 12d of the second frame 12 may be immediately adjacent, with or without interconnection, on each two adjacent ends. As shown in fig. 1, the second frame 12 may be individually framed, wherein the

respective sheets

12a, 12b, 12c, 12d of the second frame 12 may be connected to each other at each two adjacent ends. A sealant may be additionally applied to the patchwork of the respective panels of the second frame 12. In a non-illustrated embodiment, the corners of the second frame 12 may each be provided on the outside with an L-shaped corner locking element made of bent sheet metal, one side of which is fixedly connected to one sheet metal part, for example by two self-tapping screws, and the other side of which is fixedly connected to the other sheet metal part, for example by two self-tapping screws.

The third frame 13 may be constructed the same as or similar to the second frame 12. The third frame 13 may comprise four

sheets

13a, 13b, 13c, 13d, which may each be formed of a fiber cement board. The third frame 13 and the second frame 12 can in particular be of identical design, which can be cost-effective.

When the window and door frame 10 is installed in a building, one of the second frame 12 and the third frame 13 faces outdoors and the other faces indoors. The second frame 12 and the third frame 13 are spaced apart from each other in the depth direction of the window and door frame 10. The depth direction may be understood as a direction substantially perpendicular to the door sash 10, or an indoor-outdoor direction.

The first frame 11 may have a low thermal conductivity compared to the second frame 12 and the third frame 13, forming a thermal break bridge between the second frame 12 and the third frame 13. The first frame 11 may be at least substantially composed of a wood material, for example the first frame 11 may be composed of cross-glued wood, hardwood, rotten wood, carbonized wood and/or composite boards. The window and door frame 10 can have good load bearing capacity and durability by the combination of the fiber cement boards of the second and

third frames

12 and 13 and the material of the first frame 11, particularly, the wood material. The window and door frame can have good thermal insulation performance due to the presence of the cold break bridge, and heat or cold cannot be substantially transferred between the second frame 12 and the third frame 13 via the first frame 11.

In an exemplary embodiment, the first frame 11 may have a depth of 150 to 200mm, for example, about 180mm, the second and

The window and door frame 10 may be symmetrically configured in a depth direction of the window and door frame, wherein the second frame 12 and the third frame 13 are identically configured, and a depth center line of the first frame 11, a center line of a distance between the second frame 12 and the third frame 13, and a center line of the thermal break bridge may coincide in the depth direction of the window and door frame 10. A sealant may be additionally applied between the second frame 12 and the first frame 11, specifically, on an outer circumferential surface of the second frame 12 and/or on an inner circumferential surface of the first frame 11. Similarly, a sealant may be additionally applied between the third frame 13 and the first frame 11, specifically, on an outer circumferential surface of the third frame 13 and/or on an inner circumferential surface of the first frame 11.

respective plates

11a, 11b, 11c, 11d of the first frame 11 by a plurality of fastening members 14, respectively. The fastening element 14 may be a self-tapping screw. All fastening elements 14 for fastening the plates of the second frame 12 to the first frame 11 lie in a common plane. All fastening elements for fastening the plates of the third frame 13 to the first frame 11 are also located in a common plane. In fig. 2, fastening elements 14 for fastening the

plates

12b and 12c of the second frame 12 to the

plates

11b and 11c of the first frame and fastening elements 14 for fastening the

plates

13b and 13c of the third frame 13 to the

plates

11b and 11c of the first frame are visible.
