Abstract
The utility model relates to a high air-tight and water-tight rail for sliding a window, and a sliding rail comprises two parallel tight surfaces. A booster cavity is arranged under the sliding rail. The height of the two parallel tight surfaces is from five millimeters to ten millimeters. An isolated rib is arranged between the booster cavity and a screw hole. The 'bulb '-shaped of the lower sliding rail of the exiting aluminium alloy sliding window is changed into a rail which is provided with two parallel tight surfaces by the utility model. The air-tight index of the aluminium alloy sliding window can be enhanced obviously under the negative pressure difference when the two inner sides of the section under the window sash are respectively provided with tight wool strips or adhesive strips. The booster cavity is added under the sliding rail. The water level difference can increase obviously when the outward drainage of the indoor water via the sliding rail holes of the exterior sash is changed into the downward and outward drainage via the booster cavity. The drainage pressure can be further enhanced, the drainage speed is accelerated, and the water-tight performance of the sliding window is enhanced. The water-tight index of the aluminium alloy sliding window is not decreased but enhanced in the condition that the pressure is increased and fluctuated. In addition, the utility model has good compatibility with other existing parts, and the utility model can be used conveniently with little change.
Description
Technical field
The utility model relates to a kind of door and window structure, sliding guide rail structure under especially a kind of aluminum alloy push-pull window.
Background technology
The downslide guide rail cross sectional shape of existing aluminum alloy push-pull door and window, as shown in Figure 1, the shape of brace rod can only be born the tight function under the outside positive pressure below its " bulb " 1, and tightness under Negative Pressure Difference and the watertightness depressed in fluctuations such as tropical storm and typhoons be extreme difference all.Therefore, can not adapt to of the requirement of new national standard, can't in highrise building and critical facility, use positive and negative calm the anger close performance and watertightness performance of external window of building.
Summary of the invention
The purpose of this utility model is to solve the problem that existing aluminum alloy push-pull door and window downslide guide rail exists, a kind of tightness index that can improve effectively under the negative pressure state is provided, and adds in fluctuation and to depress the sliding sash guide rail that still can not reduce even improve again watertightness performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high airtight, high watertight sliding sash guide rail, to form by aluminium alloy extrusions, and slide rail is made up of two parallel sealing faces, is provided with booster cavity below the slide rail.The height of two parallel sealing faces is 5 to 10 millimeters; Be provided with isolation bar between booster cavity and the screw hole.
The beneficial effects of the utility model are: owing to existing aluminum alloy push-pull window downslide guide rail " bulb " shape is had the guide rail of two parallel sealing faces instead, when square stock the inside two sides all were equipped with seal weatherstrip or adhesive tape under the sash, the tightness index of aluminum alloy push-pull window under Negative Pressure Difference will obviously improve; Increase booster cavity below the slide rail, when making into downwards by the outside draining of booster cavity by the outside draining in exterior wing slide rail hole by indoor water, water-head will obviously increase, can further improve discharge pressure, accelerate drainage speed, improve the watertightness performance of sliding sash, therefore, under fluctuation pressurization situation, the watertightness index of aluminum alloy push-pull window does not only descend, and can increase on the contrary.In addition, good with existing other part compatibility, only need to change a little and just can use easily.
Description of drawings
Accompanying drawing 1 is the aluminum alloy push-pull window downslide guide rail sectional view of prior art;
Accompanying drawing 2 is downslide guide rail sectional views of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 2, the utility model is made up of aluminium alloy extrusions, and " bulb " shape of existing aluminum alloy push-pull window downslide guide rail is had the slide rail of two parallel sealing faces 2 instead, and the height of two parallel sealing faces 2 is 5 to 10 millimeters.When square stock the inside two sides all were equipped with seal weatherstrip or adhesive tape under the sash, the tightness index of aluminum alloy push-pull window under Negative Pressure Difference will obviously improve.Be provided with booster cavity 3 below the slide rail.Indoor water can increase the water-head of draining by booster cavity 3 outside drainings, improves discharge pressure and speed, thereby improves the watertightness performance of sliding sash.Be provided with isolation bar 4 between booster cavity 3 and screw 5 holes, screw 5 and booster cavity 3 are isolated.10 millimeters places, booster cavity 3 two ends the insides are blocked with the injection moulding baffle plate, and the space between it and the banding is filled with foam filled dose.Bore aperture from banding during operation and inject foam filled dose, with the anxiety of stopping to leak.
Claims (3)
