Door and window structure with high water tightness
Technical Field
The utility model relates to a door and window technical field, concretely relates to door and window structure of high water tightness.
Background
The door and window is an indispensable important component in the building and has the functions of lighting, wind prevention, rain prevention, theft prevention and the like. The existing door and window system generally comprises glass and a frame body for fixing the glass, wherein the frame body comprises an outer frame and an inner sash, the outer frame is used for fixing with a building wall, and the inner sash is used for fixedly mounting the glass. And (3) inspecting the performance of the door and window, wherein the water tightness is an important index.
The watertightness of the door and window refers to the capability of preventing rainwater from leaking under the action of wind and rain when the door and window is in a normal closing state. In the prior art, in order to improve the water tightness of the door and window, 3 sealing rubber strips are installed between the inner sash and the outer frame, as shown in fig. 1.
As can be seen from the figure, the outdoor side, the indoor side and the center of the joint of the inner fan and the outer frame are respectively provided with a sealing rubber strip to form three seals, the outdoor side sealing rubber strip is used for blocking rainwater, the indoor side sealing rubber strip is used for blocking outdoor gas, and the central sealing rubber strip is used for blocking a cavity between the inner fan and the outer frame, so that rainwater is effectively blocked from entering the indoor space under the action of outdoor wind pressure. Under the wind pressure effect, interior fan can form certain displacement towards indoor direction, and the frame keeps fixed, consequently, forms the gap between interior fan and the frame, and indoor side joint strip and outdoor side joint strip can't compensate this gap, and the rainwater just can the infiltration. Therefore, a central sealing rubber strip is required to be arranged in the cavity between the inner fan and the outer frame so as to solve the problems.
However, the price of the central sealing rubber strip is expensive, and the price of the central sealing rubber strip is about 5 yuan/m, so that the production cost of the door and window is greatly increased. Moreover, because the inside structures of fan and frame are different in the different producers, in order to fill the cavity between fan and the frame in, need carry out customization central joint strip to different interior fan and frame structures, and the installation is loaded down with trivial details.
Therefore, a door and window structure with good waterproof performance and low cost is urgently needed in the market.

Because interior fan and glass can be to indoor emergence skew under the effect of outdoor wind pressure, consequently the gap between interior fan and the frame can the grow, and the setting of trailing adhesive tape, because its width is greater than the distance between interior fan and the frame, consequently, the gap grow between interior fan and the frame, the trailing adhesive tape expandes to keep the seal in gap all the time, guarantee the water proofness.
In a specific embodiment, a front fin plate is arranged at the front end of the outer frame, an adhesive tape groove is formed in one side of the front fin plate, which faces away from the outdoor space, and one side of the trailing adhesive tape is clamped in the adhesive tape groove; the middle front part of the bottom of the inner fan is provided with an adhesive tape lap joint point, and the other side of the trailing adhesive tape is fixed on the adhesive tape lap joint point; the width of the trailing adhesive tape is larger than the distance between the adhesive tape groove and the adhesive tape lap joint point.
In a specific embodiment, a connecting plate perpendicular to the front fin plate is integrally arranged on one side of the middle of the front fin plate, which faces away from the outdoor space, a drain hole is formed in the front fin plate, the height of the rear side of the drain hole is flush with the height of the front end of the connecting plate, the bottom of the drain hole is in a slope shape, and the height of the front end of the drain hole is lower than that of the rear end. Because the effect of the dead weight of water and wind pressure, can have a small amount of water and get into the frame through the gap between adhesive tape groove and the trailing adhesive tape, through setting up the wash port, can be fast with this part of water discharge frame.
In a specific implementation mode, the front end of the inner fan is provided with a front plate, and the bottom of the front plate is provided with tooth-shaped dripping convex points. As is well known, when water drops flow down along a vertical plane, if the bottom of the vertical plane is a horizontal plane, the water drops flow backwards after flowing to the bottom of the vertical plane; when the bottom of the vertical plane is provided with a bulge, water drops can be gathered on the bulge and then vertically drip. The utility model discloses a be exactly this principle, through setting up the bump that drips, prevent rainwater infiltration backward.
In a specific embodiment, a water diversion line is arranged on one side surface of the front plate facing outdoors, and the lower end of the water diversion line is converged above the water dripping salient point.
In a specific implementation mode, the bottom of the inner fan is provided with a water leakage hole, the water leakage hole is close to one side of the front plate back to the outdoor, and the water leakage hole is connected with the water dripping salient points through arc slopes. In order to avoid the gap appearing between glass and the interior fan and make the inside of interior fan fill water, set up the log raft play in the hole in time will interior fan that leaks to cause through the arc slope and drip on the water dropping bump.
In one embodiment, the joint between the glass and the inner sash is provided with a sealant.
In a specific embodiment, the top of the side of the front fin plate facing outdoors is provided with a chamfer, and when the wind pressure is 0, the chamfer is positioned under the dripping convex point or closer to indoors than the dripping convex point. The chamfer is arranged, and when rainwater drops from the lower part of the dripping convex point, the rainwater can strike the chamfer and sputter towards the outdoor direction, so that the rainwater amount sputtered towards the indoor direction is reduced.
In one embodiment, a sealing rubber strip is arranged between the outdoor side of the outer frame and the outdoor side of the inner fan.
In a specific implementation mode, the material of the outer frame and the inner sash is glass fiber reinforced polyurethane, and the material is high in strength and light in weight, so that the light weight of the door and window is facilitated.
