Abstract

The utility model discloses a plastic side-hung casement (door). On the basis of the original structure, the plastic casement changes special shape pipe battens to L-shaped battens and omits a clamping groove which is matched with the battens on a casement frame. Simultaneously, the utility model accordingly reduces the dimensions of the fixing edge and the sealing edge of the glass casement, and the battens can adjust the pressing locations of the battens according to the thickness of the glass casement in a non-stage mode. The utility model ensures the stability and the sealability after the glass casement is installed, increasing lighting quantity and simplifying the structure and the molding technology of the casement frame and the battens. The utility model can lower material consumption by 15-20 % and reduces production cost by above 20 %. Consequently, the utility model overcomes the defects that the normal plastic casement (door) is complicated in structure, large in material consumption, high in cost, etc.

Description

A kind of flat opening plastic window

The utility model belongs to the flat opening plastic window in the builing industry, is particularly suitable for being used as window in the general civil building: also can be used as the glass window.

The present plastic window of in industry and civilian construction industry, using, though have non-corrosive, without putrefaction, exquisite appearance, characteristics such as sealing and soundproof effect are good; But exist design unreasonable, material consumption height, therefore defective such as hold at high price influences it and applies.For example: with Ministry of Construction approval atlas on probation number be that 45 series, 1.2 * 1.2 casement windows are example in " the Vybak steel casement door window " of 92SJ704, its plastics consumption promptly reaches the 10.5kg/ shelves, and every construction cost per square meter exceeds same specification timber window about 1/3.Press strip wherein is owing to employing polygon special section tubular product, and the fixedly card that also is provided with the sealing mat caulking groove and supplies to be connected with window frame on the outer wall of tubing, and the cross-sectional area of whole press strip promptly reaches 3.5cm ²About.Not only volume is big, and complex structure, consumptive material is many, its weight promptly accounts for about 16% of whole forms (except that glass) total amount, and the band on sash framework and window frame seals fixing (or claiming the location) limit of caulking groove in addition, in order to adapt with it, also bootlessly increased its physical dimension, the width of the gulde edge on two frameworks is 20mm, consumptive material not only, and reduced daylighting area.Therefore, the plastic door-window of this class formation exists disadvantages such as complex structure, material consumption and cost of production height.

The purpose of this utility model is the plastic window (door) that a kind of structure of design is simple relatively, the material consumption amount is low, reduces production and use cost to reach, in order to purpose such as applying.

Solution of the present utility model is on the original structure basis, change the special-shaped tubular type press strip of polygon into L shaped press strip, save the draw-in groove that is connected with special-shaped tubular type press strip that is used as that is provided with on the sash frame simultaneously, and corresponding fixed edge corresponding width of dwindling band seal caulking groove on window frame, the sash; Adopt tapping screw to be connected between L type press strip and the window frame, and can be according to its compacted position of the stepless adjustment of the thickness of window glass, thereby reach its purpose.Therefore, the utility model comprises the open-core type framework that is divided on window frame and the sash and is positioned on the two framework frames and the fixed edge of band seal caulking groove and be embedded in the sealing mat of this groove or weather strip is fixed in window glass and press strip on the window frame: key is that the fitting face when two frameworks are closed and the side window glass embedding face of window frame are the plane, and the width of fixed edge only is about 60% of a former width on two frameworks; The press strip of fixed casement window glass then is L shaped press strip, and this press strip outside on one side also is provided with the zigzag bayonet socket in order to the fixing seal pad, and another side then is fastenedly connected with the fixed casement window glass by the framework of tapping screw and sash, and sash and window frame flexibly connect by hinge.The width of the fixed edge of band seal caulking groove generally is advisable with 11～13mm on above-mentioned two frameworks.

The utility model is owing to change special-shaped tubular type press strip into L shaped press strip, saved on the sash fixedly caulking groove of corresponding press strip simultaneously, and dwindled on the framework with the tubular type press strip adapts and fixed the size of sealing strip.Therefore, both guarantee stability and sealing after the window glass is installed, increased lighting quantity, simplified the structure and the moulding process of framework and press strip again, greatly reduced raw-material consumption and cost of production simultaneously; In addition, owing to can infinitely set up its permanent position arbitrarily by tapping screw between press strip and the sash, be not subjected to the influence of window glass thickness when therefore installing.The utility model is compared with the conventional plastic door-window of same specification, can save material 15～20%, and cost of production descends more than 20%.Therefore, the utlity model has simple in structure, stability and good airproof performance, daylighting area is bigger, produce and use cost is low, to characteristics such as the thickness compliance of window glass are strong.
