Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to an outer window assembly. Background Art

[0002] As an important part of the building maintenance system, windows not only improve the light transmittance and ventilation effect of the room, but also have an important basic performance of waterproofing. After the window is installed in the window hole, although the gap between the window frame and the window hole will be filled with cement mortar or foam material, liquid (such as rainwater) will still penetrate into the room along the interface between the filler and the window hole and window frame, causing indoor building materials to become damp, moldy and deformed.

[0003] In order to solve the above problems, the prior art generally sets a water-shedding plate to limit the liquid from penetrating into the room, such as Figure 1 As shown, the outer window assembly specifically includes a window frame 01, a water drop board 02 and fixing screws 03. Specifically, after the window frame 01 is assembled, the water drop board 02 is installed on the side of the window frame 01 close to the outside, and the water drop board 02 is fixed to the window frame 01 by fixing screws 03.

[0004] In the above-mentioned prior art solution, after installation and fixation, the contact surface between the dripping board 02 and the window frame 01 is a vertical surface, and the vertical gap between the dripping board 02 and the window frame 01 will still become a channel for liquid to penetrate. Therefore, sealant is usually applied to the joint between the dripping board 02 and the window frame 01 to further prevent rainwater from penetrating into the room through the joint between the dripping board 02 and the window frame 01. However, the sealant is easily washed away by water after being used for a period of time, thereby causing water to seep through the vertical gap between the dripping board 02 and the window frame 01. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the defect of water seepage in the vertical gap between the shedding plate and the window frame in the prior art, thereby providing an exterior window assembly.

[0006] In view of this, the utility model provides an outer window assembly, comprising:

[0007] window frame;

[0008] A water shedding plate is connected to the outer side of the window frame, the water shedding plate includes a water shedding portion, the water shedding portion includes a water receiving portion and a fixing portion, the fixing portion extends under the window frame, and the water receiving portion is arranged to be inclined downward from an end close to the window frame to an end away from the window frame.

[0009] Beneficial effects: The exterior window assembly provided by the utility model, by extending the fixed part of the spouting board under the window frame, changes the vertical gap originally exposed to the outside of the window frame into a horizontal gap blocked by the window frame. When rain drops onto the spouting board, due to the obstruction of the window frame, the rain will only fall on the surface of the water-facing part of the spouting board, and the water-facing part inclined downward can guide the rain to flow away from the window frame, thereby preventing rain from extending into the room along the gap between the window frame and the spouting board, thus protecting indoor building materials. At the same time, since the spouting board is not connected and fixed to the window frame, it only needs to be inserted under the window frame when installing the spouting board, thus avoiding the problem of the spouting board being difficult to install due to window construction errors and simplifying the installation operation. Furthermore, compared with the traditional spouting board, the spouting board with the water-facing part inclined downward increases the field of view of the window and improves the use effect of the window.

[0010] In an optional embodiment, the angle between the water-facing portion and the horizontal plane is between 1° and 15°.

[0011] In an optional embodiment, a mounting channel is provided under the window frame, and a size of the mounting channel matches a size of the drip board; and / or a sealant is provided at the connection between the window frame and the drip board.

[0012] Beneficial effect: By matching the size of the installation channel with the size of the spouting board, the size of the connection between the spouting board and the window frame can be minimized. By providing sealant at the connection between the window frame and the spouting board, when the exterior window assembly faces rainfall exceeding the design requirements, the sealant can be used as an auxiliary means to seal the connection between the window frame and the spouting board to prevent rainfall exceeding the design index from pouring into the bottom of the window frame.

[0013] In an optional embodiment, the fixing portion is coplanar with the water-facing portion.

[0014] Beneficial effect: By arranging the fixed part and the water-facing part on the same plane, the structure is simpler and the processing is more convenient compared with the water-shedding board in the prior art, which reduces the production cost of the water-shedding board. At the same time, since the fixed part and the water-facing part are on the same plane, the entire water-shedding board structure is on the same plane, and can be packaged and transported in the form of steel coils. During on-site processing, it only needs to be cut according to the size of the window hole, which further reduces the transportation, storage and processing costs of the external window components.

[0015] In an optional embodiment, a window hole is provided below the window frame, and the window frame and the window hole are fixedly connected by a first fastener;

[0016] One end of the fixing portion away from the water-receiving portion is arranged on a side of the first fastener away from the water-receiving portion, and the fixing portion is fixedly connected to the window frame via the first fastener.

[0017] Beneficial effect: The first fastener originally used to fix the window frame is used to reinforce the drip board, so that the drip board is fixed more firmly.

[0018] In an optional embodiment, the fixing portion and the water-facing portion are arranged at a certain angle.

[0019] Beneficial effect: by setting the fixing part at a certain angle with the water-facing part, the fixing part can also play the role of a water retaining strip. When the rainfall is too heavy or the sealant is not sealed tightly or fails due to aging, it can prevent water from flowing over the spouting board and entering the room, thereby further improving the water retaining effect of the spouting board.

[0020] In an optional embodiment, the fixing portion and the water-facing portion are arranged at an obtuse angle.

[0021] In an optional embodiment, at least one protrusion is provided below the window frame, the fixing portion is provided on a side of the protrusion away from the water facing portion, and the fixing portion cooperates with the protrusion to fix the water shedding board.

[0022] Beneficial effect: In order to increase the structural strength of the window frame and facilitate assembly, at least one raised portion is provided at the bottom of the window frame, and the fixing portion is provided on the side of the raised portion away from the water-facing portion. The raised portion cooperates with the fixing portion to prevent the water-shedding plate from moving away from the window frame, thereby further improving the assembly stability of the water-shedding plate. At the same time, the above fixing method can also use a traditional Z-shaped water-shedding plate, so the traditional outer window assembly can be easily transformed into the technical solution provided by the utility model.

[0023] In an optional embodiment, two protrusions are provided below the window frame, and the fixing portion extends between the two protrusions.

[0024] Beneficial effect: the fixing part is extended between the two raised parts, which limits the installation range of the water-shedding plate, improves the assembly accuracy and simplifies the installation method.

[0025] In an optional embodiment, the fixing portion is fixedly connected to the two protruding portions via a second fastener.

[0026] Beneficial effect: The fixing portion extending between the two protrusions is fixedly connected by a second fastener, which on the one hand improves the installation stability of the spout, and on the other hand makes the fixing portion contact with the protrusion, thereby improving the sealing between the spout and the window frame, and further improving the water-blocking ability of the spout.

DETAILED DESCRIPTION

[0033] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The following is combined with Figure 2 , describing an embodiment of the utility model.

[0035] As attached Figure 2 As shown, according to an embodiment of the utility model, an exterior window assembly is provided, comprising: a window frame 1; a dripping plate 3, connected to the outer side of the window frame 1, the dripping plate 3 comprises a dripping portion, the dripping portion comprises a water facing portion 31 and a fixing portion 33, the fixing portion 33 extends under the window frame 1, and the water facing portion 31 is arranged to be inclined downward from an end close to the window frame 1 to an end away from the window frame 1.

[0036] By extending the fixing portion 33 of the shedding board 3 under the window frame 1, the vertical gap originally exposed to the outside of the window frame 1 is changed into a horizontal gap blocked by the window frame 1. When rain drops onto the shedding board 3, due to the obstruction of the window frame 1, the rain will only fall on the surface of the water-facing portion 31 of the shedding board 3, and the water-facing portion 31 tilted downward can guide the rain to flow away from the window frame 1, thereby preventing the rain from extending into the room along the gap between the window frame 1 and the shedding board 3, thus protecting the indoor building materials. At the same time, since the shedding board 3 and the window frame 1 do not need to be connected and fixed with screws, when installing the shedding board 3, it is only necessary to insert the shedding board 3 under the window frame 1, thus avoiding the problem of the shedding board 3 being difficult to install due to window construction errors, thereby simplifying the installation operation. Furthermore, compared with the traditional shedding board 3, the shedding board 3 with the water-facing portion 31 tilted downward increases the field of view of the window and improves the use effect of the window.

[0037] Specifically, the length of the fixing portion 33 in this embodiment is 30 mm. Of course, the length of the fixing portion 33 can also be adjusted according to specific needs, and no excessive restrictions are made here.

[0038] The shedding plate 3 in this embodiment also includes a lower hanging portion 32, which is connected to the side of the water-facing portion 31 away from the fixed portion 33. The lower hanging portion 32 can better guide the water flow, and also serves to shield the connection between the shedding plate 3 and the window hole 5 of the fixed window frame 1, thereby improving the aesthetics of the outer window assembly. Specifically, the length of the lower hanging portion 32 is 50 mm, and of course, the length of the lower hanging portion 32 can also be adjusted according to specific needs, and no excessive restrictions are made here. As a convertible embodiment, it is also possible that the shedding plate 3 only includes the shedding portion.

[0039] In this embodiment, the angle between the water-facing portion 31 and the horizontal plane is between 1° and 15°, with 5° being the best choice. When the angle between the water-facing portion 31 and the horizontal plane is too small, rainwater cannot smoothly flow away from the window frame 1. When the angle is too large, it is difficult to install the water-shedding plate 3. Therefore, the 5° angle setting is the best choice considering both the water flow guiding effect and the installation construction difficulty.

[0040] In this embodiment, a mounting channel is provided below the window frame 1, and the size of the mounting channel matches the size of the water-shedding board 3. Specifically, the mounting channel is Figure 2 The size of the installation through hole below the side wall of the middle window frame 1 on the outdoor side matches the size of the water-shedding plate 3, which can prevent a large gap between the water-shedding plate 3 and the window frame 1 from causing water seepage.

[0041] In this embodiment, the connection between the window frame 1 and the water-shedding board 3 is provided with a sealant 34, and the sealant 34 is a commonly used sealant such as silicone sealant, polyurethane sealant, or polysulfide sealant. By providing the sealant 34 at the connection between the window frame 1 and the water-shedding board 3, when the outer window assembly faces a rainfall exceeding the design requirement, the sealant 34 can be used as an auxiliary means to seal the connection between the window frame 1 and the water-shedding board 3 to prevent the rainfall exceeding the design index from pouring into the bottom of the window frame 1. As a convertible embodiment, it is also possible that the sealant 34 is not provided at the connection between the window frame 1 and the water-shedding board 3.

[0042] The fixed portion 33 in this embodiment is coplanar with the water-facing portion 31. Compared with the water-shedding plate 3 in the prior art, the structure is simpler, the processing is more convenient, and the production cost of the water-shedding plate 3 is reduced. At the same time, since the fixed portion 33 is coplanar with the water-facing portion 31, the entire water-shedding plate 3 structure is in the same plane, and can be packaged and transported in the form of steel coils. When processed on site, it only needs to be cut according to the size of the window hole 5, which further reduces the transportation, storage, and processing costs of the outer window assembly. As a convertible implementation method, it can also be that the fixed portion 33 and the water-facing portion 31 are set at a certain angle, specifically, they can be set at an obtuse angle, of course, they can also be set at other angles, and there is no excessive restriction here. By setting the fixed portion 33 and the water-facing portion 31 at a certain angle, the fixed portion 33 can also play the role of a water retaining strip. When the rainfall is too large or the sealant 34 is not tightly sealed or aged and fails, it prevents water from flowing over the water-shedding plate 3 and entering the room, further improving the water retaining effect of the water-shedding plate 3.

[0043] In this embodiment, a filler 8 is provided between the window frame 1 and the window hole 5, and the fixing portion 33 extends into the filler 8. Specifically, the filler 8 is foam glue, and the foam glue is polyurethane foam glue, silicone foam glue or polystyrene foam glue, etc. As a convertible embodiment, the filler can also be a caulking material such as cement mortar.

[0044] In this embodiment, a window hole 5 is provided below the window frame 1, and the window frame 1 and the window hole 5 are fixedly connected by a first fastener 4. Figure 2 As shown, the first fastener 4 is a tail thread, specifically, the tail thread is a self-tapping screw, and the specific specification of the tail thread is ST4.8*25. Of course, the specification of the tail thread can also be adjusted according to specific needs, and no excessive restrictions are made here.

[0045] In this embodiment, a transition piece 6 is further provided between the window frame 1 and the window opening 5. The provision of the transition piece 6 is conducive to the early closing of doors and windows, and improves the construction speed and efficiency. The transition piece 6 specifically includes a square tube 61 and a connecting piece 62. The square tube 61 and the connecting piece 62 are fixedly connected by screws. The connecting piece 62 is fixedly connected to the window opening 5 by nails 63. The square tube 61 is fixedly connected to the window frame 1 by a first fastener 4. An auxiliary filler is provided between the connecting piece 62 and the window opening 5. The auxiliary filler is polyurethane foam, silicone foam or polystyrene foam. As a convertible embodiment, the auxiliary filler can also be a caulking material such as cement mortar.

[0046] In this embodiment, the connection between the window frame 1 and the window hole 5 near the indoor side is provided with indoor sealant 7. As a changeable embodiment, it is also possible that the connection between the window frame 1 and the window hole 5 near the indoor side is not provided with indoor sealant 7.

[0047] The window frame 1 of the present embodiment is provided with an opening fan 2, and sealing materials such as glass, resin, film, etc. may also be provided according to actual needs.

[0048] There are many ways to fix the fixing portion 33 and the window frame 1. In this embodiment, one end of the fixing portion 33 away from the water-receiving portion 31 is arranged on the side of the first fastener 4 away from the water-receiving portion 31, and the fixing portion 33 and the window frame 1 are fixedly connected by the first fastener 4. The first fastener 4 originally used to fix the window frame 1 is used to reinforce the water-receiving plate 3, so that the fixing of the water-receiving plate 3 is more firmly, and no additional fasteners are required for fixing, which saves the number of parts.

[0049] The water-shedding plate 3 in this embodiment is an aluminum water-shedding plate with a thickness of 1.5 mm. As a convertible implementation, the water-shedding plate 3 of different thicknesses made of other materials may also be used.

[0050] In this embodiment, a heat-insulating layer 51 is provided between the water-shedding plate 3 and the transition piece 6. The heat-insulating layer 51 is a heat-insulating mortar, which is used to improve the heat-insulating effect of the building. As a changeable implementation method, other heat-insulating materials can also be used.

[0051] In this embodiment, the back of the water-shedding plate 3 is covered with double-sided tape to assist in fixing the water-shedding plate 3. Of course, in other embodiments, the back of the water-shedding plate 3 may not be provided with double-sided tape, and no excessive restrictions are made here.

[0052] The specific method of installing the outer window assembly in the embodiment of the present application includes:

[0053] S1. Clean the window hole 5 and draw the installation line of the water board 3 on the outside of the window hole 5;

[0054] S2. Tear off the protective film of the double-sided tape on the back of the water plate 3, install the water plate 3 at a drainage slope of 5%, extend the fixing portion 33 into the filler 8 under the window frame 1 close to the middle drill tail position, and press the water plate 3 into place;

[0055] S3. Filling the filler 8 between the window frame 1 and the window hole 5;

[0056] S4. Apply sealant 34 to the connection between the window frame 1 and the sheathing board 3.

[0057] In other embodiments, a raised portion 11 is provided below the window frame 1, and a fixing portion 33 is provided on a side of the raised portion 11 away from the water-facing portion 31, and the fixing portion 33 cooperates with the raised portion 11 to fix the water-shedding plate 3. When installing the water-shedding plate 3, the water-facing portion 31 is tilted, and the fixing portion 33 is first extended into the window frame 1 until it is away from the raised portion 11, and then the water-shedding plate 3 is rotated to the installation position. In order to increase the structural strength of the window frame 1 and facilitate assembly, a raised portion 11 is provided below the window frame 1, and the fixing portion 33 is provided on a side of the raised portion 11 away from the water-facing portion 31, and the raised portion 11 cooperates with the fixing portion 33 to block the water-shedding plate 3 from moving away from the window frame 1, and further improves the assembly stability of the water-shedding plate 3 without increasing the cost of the window frame. At the same time, the above fixing method can also use a traditional Z-shaped water-shedding plate, so it is very convenient to transform the traditional outer window assembly into the technical solution provided by the utility model.

[0058] In other embodiments, two protrusions 11 are provided below the window frame 1 near the outdoor side of the window frame, and the fixing portion 33 extends between the two protrusions 11.

[0059] The fixing portion 33 is fixedly connected to the two protrusions 11 by a second fastener. The fixing portion 33 extending between the two protrusions 11 is fixedly connected by a second fastener, which improves the installation stability of the water-shedding plate 3 on the one hand, and makes the fixing portion 33 contact with the protrusions 11 on the other hand, thereby improving the sealing between the water-shedding plate 3 and the window frame 1, and further improving the water-blocking ability of the water-shedding plate 3.

[0060] Specifically, the second fastener is a screw, which penetrates the protrusion 11 near the outside of the window frame 1 from the outside of the window frame 1, and then penetrates the fixing portion 33 and the inner protrusion 11, fixing the fixing portion 33 to the two protrusions 11. Alternatively, the screw penetrates the protrusion 11 near the outside of the window frame 1, and abuts against the fixing portion 33, and abuts the fixing portion 33 against the inner protrusion 11.

[0061] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
