Description

Technical Field

[0001] The utility model relates to the field of caulking waterproofing, in particular to a waterproofing device for window frame connection seams. Background Art

[0002] In the door and window installation project, filling the gaps between doors and windows is a crucial step. At present, cement and foam glue are two common filling materials between window frames and walls. Due to the large amount of cement used and the long construction time, expansion joints are easily generated due to thermal expansion and contraction, and the subsequent seam treatment is required for aesthetics, which is rather troublesome. The construction process of foam glue is more convenient and time-saving, so foam glue is often used to fill the gaps. However, foam glue is easily affected by weather factors such as sunlight, rain and snow when used for a long time in an open air environment, and is easily oxidized. Its weather resistance is poor, so it is easy for water to accumulate in the gaps and even penetrate into the inside of the window frame, affecting user use. Therefore, it is necessary to provide a waterproof device for window frame connection seams that has a simple structure and can effectively fill gaps and avoid water accumulation.

[0026] The window frame connection seam waterproofing device of this scheme is suitable for filling the gap of the door and window frames. First, the inner side of the base 4 is aligned with the gap of the door and window frames, and the base 4 is pressed into the gap, so that the deformation strip 5 and the arc-shaped support portion 42 are compressed toward the middle of the base 4 to fill the gap space. Due to the compression of the gap, the base 4 causes the support arm 41 to tilt upward and form a triangular support structure with the base 4 to improve the support strength of the base 4; then, the waterproof glue is injected through the first connecting hole 52, and the waterproof glue is compressed in the deformation hole 5 1, and flows into the support cavity surrounded by the support arm 41 and the base 4 along the second connecting hole 53, so as to strengthen the support structure surrounded by the support arm 41 and the base 4; in addition, after a certain amount of glue is poured into the deformation hole 51, part of the glue flows out along the third connecting hole 54, and the part of the glue that flows out is led to the arc support part 42 along the inner side of the base 4, further filling the gap and strengthening the bonding between the arc support part 42 and the gap installation surface, so as to prevent external rainwater from penetrating along the gap, so as to achieve waterproofing of the gap of the door and window frame.

[0027] In this embodiment, Figure 2 As shown, a buckle 44 is provided on the lower side of the top of the base 4, and a hook 43 adapted to the buckle 44 is provided at the end of the extended part of the support arm 41. The hook 43 is pressed toward the inner side of the base 4 so that the hook 43 is buckled into the buckle 44 to connect the support arm 41 to the lower side of the top of the base 4.

[0028] Specifically, the left side of the base 4 is the outer side, and an upwardly inclined support arm 41 is provided in the middle of the outer side of the base 4. The left end of the support arm 41 is bent and extended upward, and a hook 43 is provided at the top end of the extended part. After the base 4 is pressed into the gap, the hook 43 is pressed to the right by the mounting rod so that the hook 43 is buckled into the buckle 44. At this time, the base 4, the support arm 41 and the extended part thereof are combined to form a triangular support structure, and glue is poured into the support cavity inside thereof to support the base 4, the support arm 41 and the extended part thereof outwardly, thereby strengthening the support structure formed by the support arm 41 and the base 4.

[0029] In this embodiment, Figure 2 As shown, the base 4 is a "7"-shaped structure, which is divided into a horizontal part and a vertical part. The deformation strip 5 is arranged on the upper side of the horizontal part, the buckle 44 is arranged on the lower side of the horizontal part, and the support arm 41 is arranged in the middle of the outer side of the vertical part.

[0031] In this embodiment, Figure 2 As shown, a limit buckle 45 is provided on the lower side of the transverse portion of the base body 4 , and the limit buckle 45 is located on a side of the buckle 44 away from the vertical portion.

[0032] Specifically, the limiting buckle 45 is located on the left side of the buckle 44. When the hook 43 of the support arm 41 is stretched outward, the limiting buckle 45 limits it to prevent the extended part of the support arm 41 from moving too far.

[0033] In this embodiment, Figure 2 As shown, a drainage bar 46 is provided at one end of the transverse portion of the base body 4 away from the vertical portion, and the drainage bar 46 is provided to be inclined downward.

[0034] Specifically, a drainage strip 46 is disposed at the left end of the transverse portion of the base 4 , and the drainage strip 46 extends downward and outward, allowing external rainwater to flow outward along the drainage strip 46 , thereby preventing external rainwater from entering the gap.

[0035] In this embodiment, Figure 2 As shown, the first connecting hole 52 is arranged on the outer side of the deformation strip 5 , the second connecting hole 53 is arranged on the bottom of the deformation strip 5 , and the third connecting hole 54 is arranged on the inner side of the deformation strip 5 .

[0036] Specifically, the first connecting hole 52 is arranged on the left side of the deformation strip 5 , the second connecting hole 53 is arranged on the bottom of the deformation strip 5 , and the third connecting hole 54 is arranged on the right side of the deformation strip 5 . The position of the first connecting hole 52 is higher than that of the third connecting hole 54 .

[0037] In this embodiment, Figure 2 As shown, the deformation strip 5 is provided with a plurality of second connecting holes 53 and third connecting holes 54 along its own length direction, and the second connecting holes 53 and the third connecting holes 54 are staggered.

[0038] Specifically, a plurality of second connecting holes 53 are evenly arranged at the bottom of the deformation strip 5 along its own length direction, and a plurality of third connecting holes 54 are evenly arranged on the right side of the deformation strip 5 along its own length direction, and the second connecting holes 53 and the third connecting holes 54 are staggered. Through the evenly arranged and staggered second connecting holes 53 and third connecting holes 54, part of the glue in the deformation hole 51 flows into the support cavity, part flows to the bottom surface of the arc-shaped support portion 42, and part remains in the deformation hole 51, so that the upper, middle and lower parts of the base 4 are all filled with glue.

[0039] In this embodiment, Figure 2 As shown, the aperture of the first connecting hole 52 is larger than the aperture of the second connecting hole 53 , and the aperture of the second connecting hole 53 is larger than the aperture of the third connecting hole 54 .

[0040] Specifically, the first connecting hole 52 is arranged to be inclined upward, and the aperture of the third connecting hole 54 gradually decreases from the deformation hole 51 to the direction away from the deformation hole 51; the first connecting hole 52 arranged to be inclined upward facilitates the injection of waterproof glue into the deformation hole 51, and part of the glue in the deformation hole 51 is sprayed further into the gap along the conical third connecting hole 54, and part of the glue that flows out flows downward along the base 4 to the arc-shaped support portion 42, and is bonded to the gap along the surface of the arc-shaped support portion 42.

[0041] In this embodiment, Figure 3 As shown, the connector 1 has a corner, and the two ends of the corner are respectively connected to the first support body 2 and the second support body 3. The upper part of the connector 1 is provided with a first connection hole 11 connected to the deformation hole 51, and the middle part of the connector 1 is provided with a second connection hole 12 connected to the support cavity.

[0042] Specifically, the corner of the connector 1 can be 30°, 60°, 90°, etc., which can be selected according to the required corner of the door and window frame. The structure of the first support body 2 is the same as the structure of the second support body 3, and they are connected through the first connecting hole 11 and the second connecting hole 12 of the connector 1.

[0043] In this embodiment, Figure 3 As shown, the top of the connecting body 1 extends outward to form a connecting portion 13, and a connecting column 14 is rotatably arranged in the connecting portion 13.

[0044] Specifically, after selecting the required connector 1 according to the corner of the required door and window frame, align the connector 1 with the gap at the corner position of the door and window frame, align the inner sides of the first support body 2 and the second support body 3 with the gaps of the adjacent two sides of the door and window frame, and press hard to press the base 4 into the gap. After the base 4 fills the gap space, press the hook 43 to the right through the installation rod so that the hook 43 is buckled into the buckle 44. At this time, the support arm 41 tilts upward and forms a triangular support structure with its extended part and the base 4. Then, rotate the connecting column 14 downward so that the connecting column 14 abuts against the bottom surface of the gap, so that the connector 1 forms a support.

[0045] Then, waterproof glue is injected through the first connecting hole 52 which is inclined upward. The waterproof glue flows in the compressed deformation hole 51 and flows into the support cavity surrounded by the support arm 41 and the base 4 along the second connecting hole 53. Part of the glue is sprayed into the gap along the conical third connecting hole 54, and part of the glue that flows out flows downward along the base 4 to the arc-shaped support part 42, and adheres to the gap along the surface of the arc-shaped support part 42. External rainwater flows out along the drainage strip 46 on the outside of the base 4, so as to prevent external rainwater from entering the gap and improve the weather resistance of the base 4.

[0046] It should be noted that the above-mentioned technical features are further combined with each other to form various embodiments not listed above, which are all deemed to be within the scope of the present utility model specification; and, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should fall within the scope of protection of the claims attached to the present utility model.
