[0032] like Figure 1-4 As shown, the utility model provides a door and window structure that can be quickly replaced, comprising: an old window frame 2 with the outer frame retaining arm and the middle stile removed, which is arranged on a wall 1, and the outer frame retaining arm is Figure 1 The old window frame 2 has a frame portion extending upward near the top of the outdoor side; a new window frame 3 is arranged on the top of the old window frame 2, and the inner end of the new window frame 3 has a second stop arm 31 extending toward the wall 1; Figure 2As shown, the new window frame 3 is arranged at the top of the old window frame 2 near the indoor side, so as to facilitate the second stop arm 31 extending from the inner side of the new window frame 3 beyond the old window frame 2 toward the wall 1; and an outer cover plate 4 is arranged between the new window frame 3 and the old window frame 2, and the outer cover plate 4 has a first stop arm 41 located outside the old window frame 2 and extending toward the wall 1; there is a sealant 5 between the first stop arm 41 and the wall 1, and between the second stop arm 31 and the wall 1. Figure 4 As shown in the figure, glass 8 is arranged on the top of the new window frame 3. The top side or bottom side is only for explaining the position. Figure 3 As shown, for better explanation, the side close to the wall 1 is the bottom side, the side far from the wall 1 is the top side, the inner side refers to the indoor side, and the outer side refers to the outdoor side.
[0033] For greater stability, polyurethane foaming agent 6 is filled between the new window frame 3 and the outer cover plate 4, and between the old window frame 2 and the outer cover plate 4. In addition, there are bolts 7 that pass through the new window frame 3, the old window frame 2, and the polyurethane foaming agent 6 between the new window frame 3 and the old window frame 2.
[0034] In order to ensure a stable connection between the new window frame 3 and the original structure, Figure 3 As shown, the first barrier arm 41 and the second barrier arm 31 are both L-shaped, and both have vertical parts and straight parts located inside and outside the old window frame 2 respectively; wherein the sealant 5 provided at the first barrier arm 41 and the second barrier arm 31 is in contact with at least the following surfaces: the surface of the wall 1, the surface of the sealant 5 between the original old window frame 2 and the wall 1, the outer surface of the vertical parts of the first barrier arm 41 and the second barrier arm 31, and the bottom surface of the straight parts of the first barrier arm 41 and the second barrier arm. The sealant 5 can also contact the inner and outer surfaces of the old window frame 2, so as to play the role of the sealant 5 with a larger contact area, and make the connection between the new window frame 3 and the old window frame 2 and the wall 1 more stable.
[0035] In order to further increase the contact area between the sealant 5 and the new window frame 3, the bottom side surfaces of the straight portions of the first retaining arm 41 and the second retaining arm 31 can also be as follows: Figure 3 As shown, it is arranged in a gully shape. Figure 3 In the embodiment, a sealant 5 is further arranged between the outer side of the new window frame 3 and the outer cover plate 4, so that the new window frame 3, the outer cover plate 4, the old window frame 2 and the wall 1 are firmly connected.
[0036] Through this solution, doors and windows can be quickly replaced without damaging the wall 1, saving time, labor and dust.
