Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically referring to a rainproof and water-blocking structure for doors and windows. Background Technology

[0002] Currently, the outer windowsills at the bottom of doors and windows are generally treated with cement mortar plastering, tiling, or wall paint for waterproofing and aesthetics. However, after long-term use, the connection between the door / window materials and the windowsill is prone to cracking due to thermal expansion and contraction, external disturbances, etc., leading to water seepage problems and even the risk of material detachment. Even with the use of sealant to assist waterproofing, as the usage time increases, the sealant is still prone to detachment and cracking between itself and the wall or door / window profiles, causing rainwater to accumulate and seep into the wall cracks. More importantly, some outer windowsills at the bottom of doors and windows are designed with a horizontal plane or an unreasonable structure with the outside higher than the inside, failing to form a slope to guide water outwards, further exacerbating the risk of water accumulation and seepage.

[0003] To address these issues, traditional solutions often employ stainless steel or other metal plates folded into "L" or "Z" shapes. These plates are then snapped together between the bottom frame profile of the door or window and the windowsill, or rest against the outer side of the bottom frame profile and cover the outer side of the windowsill, before being secured to the bottom frame with screws to achieve drainage. However, this type of structure has significant drawbacks: Firstly, it is difficult for the metal plate to completely fit against the bottom frame profile, leaving gaps that allow rainwater to seep in. Even with sealant filling these gaps, there is still a risk of sealant aging, failure, and cracking, leading to further water leakage. Secondly, the use of sealant can easily clog the drainage holes on the outer side of the bottom frame, creating new drainage problems. Furthermore, exposed screws not only affect the aesthetics but are also prone to rust and loosening, reducing structural stability. In addition, traditional metal plate fixing methods are cumbersome to install, have poor adaptability, and cannot meet the installation requirements of different door and window profiles. Therefore, developing a reliable, efficient, sealant-free, easy-to-install, aesthetically pleasing, and durable rainproof and water-blocking structure for the bottom frame of doors and windows has become an urgent technical problem to be solved in the industry. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a rainproof and water-blocking structure for doors and windows.

[0005] This utility model is achieved through the following technical solution: a rainproof and water-blocking structure for doors and windows, mainly composed of a lower frame body, a water-blocking plate, and a fixing cavity with an open end formed on the lower frame body; an upper fixing end is provided inside the fixing cavity and at the upper end of the open end, and a lower fixing end is provided inside the fixing cavity and at the lower end of the open end; an upper clip and a lower clip are provided at the upper end of the water-blocking plate, and the water-blocking plate is connected to the lower frame body through the cooperation of the upper clip with the upper fixing end and the cooperation of the lower clip with the lower fixing end.

[0006] As a preferred embodiment, the fixing cavity is located inside the lower frame body; the outer wall surface of the opening end is located on the same side as the outer wall surface of the lower frame body, or the outer wall surface of the opening end is located inside or outside the outer wall surface of the lower frame body.

[0007] As another preferred embodiment, the fixing cavity is located on the outer surface of the lower frame body.

[0008] To achieve better fit and fixation, the upper clip and the upper fixed end are mutually matching buckle heads or arc-shaped buckle edges, and the lower clip and the lower fixed end are mutually matching buckle heads or arc-shaped buckle edges.

[0009] The upper and lower clips are arranged in parallel or in a V-shape.

[0010] The water baffle is a straight plate or an arc plate.

[0011] The water baffle is composed of a fixed plate, a connecting plate and a lower folding plate. The fixed plate is located on one side of the connecting plate and connected to one end of the connecting plate, while the lower folding plate is located on the other side of the connecting plate and connected to the other end of the connecting plate. The upper and lower clamps are located at the ends of the fixed plate.

[0012] The lower edge of the water baffle is lower than the plane where the bottom of the lower frame body is located.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] (1) The water baffle of this utility model is connected to the lower frame body by the buckle between the upper clip and the upper fixed end of the fixed cavity, and the lower clip and the lower fixed end of the fixed cavity, forming a double-clamping structure. There is no need for exposed screws and sealant, which avoids connection failure caused by screw corrosion and loosening, and eliminates the problem of sealant aging and cracking and clogging of drainage holes. It effectively blocks the path of rainwater seeping in along the gap, and the sealing and waterproofing effect is long-lasting and stable.

[0015] (2) The lower edge of the water baffle of this utility model is lower than the plane of the bottom of the lower frame body, and can be designed as a straight plate, an arc plate or a multi-segment structure with a lower fold plate. With the reasonable layout of the opening end of the fixed cavity, it can form an efficient drainage slope that tilts outward, quickly guides rainwater to drain outward, and solves the problem of rainwater accumulation caused by unreasonable slope design or defects in the water baffle structure of traditional windowsills from the root.

[0016] (3) This utility model adopts a snap-on assembly design, which can quickly connect the water baffle and the lower frame body without complicated tools, greatly improving the installation efficiency; the fixing cavity can be set inside or on the outer side of the lower frame body, the upper and lower clips can be set in parallel or V-shape, the shape of the water baffle can be flexibly adjusted, and it can be adapted to different types and specifications of door and window profiles, with a wide range of applications, and reduces the material and labor costs in the construction process.

[0017] (4) The present invention has no exposed fasteners and sealant marks, and the overall structure is simple and neat, which improves the appearance of the doors and windows. The buckle connection between the water baffle and the lower frame body avoids the hard contact wear between the traditional metal plate and the profile. Moreover, each component can be made of suitable weather-resistant materials, with excellent anti-aging and anti-corrosion performance, which effectively extends the overall service life of the rainproof and water-blocking structure of the doors and windows and reduces the frequency and cost of later maintenance.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] Example

[0024] The rainproof and water-blocking structure for doors and windows described in this embodiment mainly consists of a lower frame body 1, a water-blocking plate 2, and a fixing cavity 3 with an open end 31 formed on the lower frame body 1. The fixing cavity 3 can be positioned inside the lower frame body 1 as needed, such as... Figure 1 As shown, it can also be set on the outer surface of the lower frame body 1, such as... Figure 2As shown. The shape of the fixing cavity 3 can be set arbitrarily. In this embodiment, it is preferably set as a rectangular structure to facilitate manufacturing and increase its compressive strength.

[0025] When the fixing cavity 3 is located inside the lower frame body 1, the opening end 31 faces the outer side of the lower frame body 1, and the outer wall surface of the opening end 31 is located on the same side as the outer wall surface of the lower frame body 1, or the outer wall surface of the opening end 31 is located inside or outside the outer wall surface of the lower frame body 1. The main purpose of setting the opening end 31 facing the outer side of the lower frame body 1 is to facilitate the installation of the water baffle 2, thereby achieving the function of rain protection through the water baffle 2.

[0026] When the fixing cavity 3 is set on the outer side of the lower frame body 1, the opening end 31 also needs to be set facing the outer side of the lower frame body 1 so as to achieve the function of rain protection through the water baffle 2.

[0027] An upper fixed end 32 is provided inside the fixed cavity 3 and at the upper end of the opening end 31, and a lower fixed end 33 is provided inside the fixed cavity 3 and at the lower end of the opening end 31. Simultaneously, an upper locking member 21 and a lower locking member 22 are provided at the upper end of the baffle plate 2. The baffle plate 2 is connected to the lower frame body 1 through the cooperation of the upper locking member 21 with the upper fixed end 32 and the lower locking member 22 with the lower fixed end 33. That is, the baffle plate 2 is fixedly connected to the lower frame body 1 by the upper locking member 21 and the lower locking member 22 being fitted into the opening end 31.

[0028] The upper locking member 21 and the upper fixed end 32 are mutually matching buckle heads or arc-shaped buckle edges. Similarly, the lower locking member 22 and the lower fixed end 33 are also mutually matching buckle heads or arc-shaped buckle edges. Furthermore, the upper locking member 21 and the lower locking member 22 can have the same structure or different structures. Figure 1 and Figure 2 The upper clip 21 and lower clip 22 shown have the same structure, both being snap-fit ​​heads; Figure 3 The upper clip 21 and the lower clip 22 shown have different structures. The upper clip 21 is achieved by using an arc-shaped buckle, while the lower clip 22 is achieved by using a buckle head.

[0029] The water-blocking plate 2 can be configured as a straight plate, an arc-shaped plate, or a bent plate, depending on the requirements. In this embodiment, the water-blocking plate 2 is preferably configured as a bent plate, and its structure is as follows: Figure 1 , 2As shown, it consists of three parts: a fixing plate 23, a connecting plate 24, and a lower folding plate 25. The fixing plate 23 and the lower folding plate 25 are located on both sides of the connecting plate 24, with one end of the fixing plate 23 connected to one end of the connecting plate 24, and one end of the lower folding plate 25 connected to the other end of the connecting plate 24. This allows the fixing plate 23, the connecting plate 24, and the lower folding plate 25 to be connected sequentially to form a shape similar to a "Z". At this time, the upper clip 21 and the lower clip 22 are fixedly installed at the end of the fixing plate 23. Depending on the actual needs, the upper clip 21 and the lower clip 22 can be arranged in parallel or in a V-shape, as long as it can be ensured that the upper clip 21 and the lower clip 22 can pass through the opening end 31 of the fixing cavity 3 and engage with the upper fixing end 32 and the lower fixing end 33, ensuring that the baffle plate 2 can be tightly fixed together with the lower frame body 1.

[0030] In this structure, the lower end of the lower fold plate 25 is the lower edge of the entire water baffle 2. Regardless of the shape or configuration of the water baffle 2, the lower edge of the water baffle 2 must be lower than the bottom plane of the lower frame body 1, thereby ensuring that the water baffle 2 can cover the lower part of the entire lower frame body 1, preventing the gap between the lower frame body 1 and the outer windowsill of the lower edge of the door and window from being exposed, and further preventing external rainwater from seeping in.

[0031] When the water baffle 2 is composed of three parts: a fixed plate 23, a connecting plate 24, and a lower folding plate 25, an angle α is formed between the plane of the fixed plate 23 and the plane of the connecting plate 24 to facilitate drainage. The value of the angle α can be set arbitrarily according to the site conditions, and its value range is generally between 90°≤α≤160°.

[0032] After installation using the above structure, the water baffle 2 can, under its own weight, allow the upper clip 21 and lower clip 22 to engage with the upper fixed end 32 and lower fixed end 33, thereby ensuring the stability of the entire water baffle 2 after installation. Simultaneously, to minimize the noise generated when rainwater drips onto the water baffle 2, the interior of the water baffle 2 can be made into one or more hollow structures, and these hollow structures are filled with foaming agent to increase their overall strength and sound insulation performance.

[0033] As described above, this utility model can be implemented quite well.
