Description
Technical Field
[0001] The utility model relates to the technical field of window waterproofing, in particular to a waterproof structure of a window without an attached frame. Background Art
[0002] Frameless windows do not require window frames and can be installed directly on the wall. Their sealing often depends on the structure of the window itself. The advantages of this type of window are easy installation, no damage to the wall, and a wide field of view. Compared with framed windows, the installation of frameless windows does not require additional processes, which can save material and time costs, and at the same time has less impact on the wall.
[0003] However, the disadvantage of frameless windows is that they have poor sealing. Water seepage channels are easily formed at the windows, and measures must be taken to carry out waterproofing construction. The conventional practice is to fill the gaps with polyurethane foam sealant. However, due to the limited lifespan of this material, simply filling the gaps with polyurethane foam sealant will still create gaps. After a long time, leakage will still occur at the connection between the frameless window and the exterior wall.
[0004] Therefore, it is particularly important to design a waterproof structure of a non-framed window to solve the above-mentioned defects. Utility Model Content

[0008] As a preferred solution of the utility model, the filling layer is composed of an anti-cracking mortar layer and a waterproof mortar layer from top to bottom.
[0009] As a preferred solution of the utility model, the drainage board is designed with an inclined structure, and multiple groups of first connecting protrusions are fixedly connected to the connection between the inner side of the drainage board and the anti-cracking mortar layer, the waterproof mortar layer and the polyurethane foam layer.
[0010] As a preferred solution of the utility model, multiple groups of second connecting protrusions are fixedly connected to the connection between the inner side of the water retaining plate and the waterproof mortar layer and the polyurethane foam layer.
[0011] As a preferred solution of the utility model, a first connecting strip is fixedly connected to the front of the window frame, a second connecting strip is fixedly connected to the top of the front of the drainage board, the top of the inner side of the waterproof board is clamped with the first connecting strip via a first connecting groove, the bottom end of the inner side of the waterproof board is clamped with the second connecting strip via a second connecting groove, and a positioning groove is provided at a position on the outer side of the drainage board corresponding to the waterproof board.

After the drain board is installed, it is in an inclined state, which is convenient for drainage of the outside of the window frame, and the first connecting strip and the second connecting strip are adhered to the outside of the window frame and the drain board, and then the waterproof board is installed through the first connecting groove and the second connecting groove. The connection between the window frame and the drain board is waterproofed by the waterproof board, and the sealing of the connection between the window frame and the drain board is further improved to effectively avoid water ingress. When the waterproof board is in use, even if water penetrates through the gap at the top of the waterproof board, it can be discharged through the drainage hole and diverted and drained through the water guide plate.

[0021] Example:
[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:
[0023] A waterproof structure for a frameless window comprises a window frame 1, the bottom of the window frame 1 is an exterior wall concrete base 2, a filling layer 3 is arranged on the top of the exterior wall concrete base 2, a polyurethane foam layer 4 is arranged between the filling layer 3 and the window frame 1, a drainage board 5 is fixedly connected to the bottom end of the front side of the window frame 1 and located outside the filling layer 3 and the polyurethane foam layer 4, a water retaining board 6 is fixedly connected to the bottom end of the back side of the window frame 1 and located outside the polyurethane foam layer 4, and a waterproof board 7 is installed at the bottom end of the front side of the window frame 1 and located outside the drainage board 5.
[0024] First, the filling layer 3 is composed of an anti-cracking mortar layer 301 and a waterproof mortar layer 302 from top to bottom. The waterproof mortar layer 302 is laid on the exterior wall concrete base 2 to improve the waterproof effect. The anti-cracking mortar layer 301 is used to level the surface and press the mesh cloth into it to prevent the surface layer from cracking in the later stage.
[0025] Then, the drain board 5 is designed with an inclined structure, and the connection between the inner side of the drain board 5 and the anti-cracking mortar layer 301, the waterproof mortar layer 302 and the polyurethane foam layer 4 are fixedly connected with multiple groups of first connecting protrusions 501. By using the multiple groups of first connecting protrusions 501, a mold cavity is formed between the drain board 5 and the water retaining plate 6, which is convenient for filling the polyurethane foam layer 4 into the space between the window frame 1 and the anti-cracking mortar layer 301. The connection between the inner side of the water retaining plate 6 and the waterproof mortar layer 302 and the polyurethane foam layer 4 are fixedly connected with multiple groups of second connecting protrusions 601. At the same time, the multiple groups of first connecting protrusions 501 and the second connecting protrusions 601 can strengthen the connection to prevent the drain board 5 and the water retaining plate 6 from loosening. After the installation is completed, the drain board 5 is in an inclined state, thereby facilitating drainage from the outside of the window frame 1.
[0026] Secondly, the front of the window frame 1 is fixedly connected with a first connecting strip 701, the top of the front of the drain board 5 is fixedly connected with a second connecting strip 702, the top of the inner side of the waterproof board 7 is clamped with the first connecting strip 701 through a first connecting groove 703, and the bottom of the inner side of the waterproof board 7 is clamped with the second connecting strip 702 through a second connecting groove 704.

After the waterproof board 7 is installed, its bottom is positioned by the positioning groove 705 to prevent it from loosening.
[0027] Finally, a plurality of drainage holes 706 are provided at equal intervals at the top of the waterproof board 7, and a water guide plate 707 is fixedly connected to the bottom of the waterproof board 7 and below the drainage holes 706. When the waterproof board 7 is in use, even if water penetrates through the gap at the top of the waterproof board 7, it can be discharged through the drainage holes 706 and drained away through the water guide plate 707.
[0028] In this embodiment, the implementation scenario is specifically as follows: a waterproof mortar layer 302 is laid on the exterior wall concrete base 2 to improve the waterproof effect, an anti-cracking mortar layer 301 is used to level the surface and press into a mesh cloth to prevent the surface layer from cracking in the later stage, a mold cavity is formed between the drainage board 5 and the water retaining board 6, and it is convenient to fill the polyurethane foam layer 4 between the window frame 1 and the anti-cracking mortar layer 301, and the drainage board 5 is in an inclined state after installation, so as to facilitate drainage of the outside of the window frame 1, and the first connecting strip 701 and the second connecting strip 702 are glued to the outside of the window frame 1 and the drainage board 5, and then the first connecting groove 703 and the second connecting groove 704 are connected. 04 The waterproof board 7 is installed, and the connection between the window frame 1 and the drainage board 5 is waterproofed by the waterproof board 7, which further improves the sealing of the connection between the window frame 1 and the drainage board 5 and effectively prevents water from entering. When the waterproof board 7 is used, even if water penetrates through the gap at the top of the waterproof board 7, it can be discharged through the drainage hole 706 and diverted and drained through the water guide plate 707. The whole operation process is simple and convenient. Compared with the existing waterproof structure of the window without an attached frame, the utility model prevents water from entering and guides it through a multi-level waterproof structure designed to effectively avoid the problem of water leakage.
