Description

Window frame seal structure

Technical Field

The utility model relates to a building door and window technical field, in particular to window frame seal structure.

Background

The broken bridge type door and window has the advantages of good heat preservation and heat insulation performance, sound insulation performance, long service life and the like, and occupies a large share in the market of building outer doors and windows. In order to make door and window drainage smoothly, generally be equipped with the drainage channel who link up from top to bottom and communicate with external environment on the window frame, ponding passes through drainage channel and discharges from the window frame is inside, but when meetting the strong wind condition, external wind pressure is great, the air, water can return inside the window frame along drainage channel, because bridge cut-off formula door and window is formed by a plurality of aluminium alloy concatenations, can gapped existence in concatenation position, drainage channel's water or air can return to indoorly from the internal clearance of window frame, make bridge cut-off formula door and window thermal-insulated, the sound insulation effect reduces.

The sealing plugging is realized by generally arranging the sealing strip in the prior art, but because the window sash assembly needs to be pushed into the window frame when being installed, if the sealing strip is too thick, great resistance can be generated to make the installation of the window sash assembly difficult, if the sealing strip is too thin, the sealing effect is not good, and part of the prior art uses the glass cushion block as the sealing strip, and because the glass cushion block needs to keep the gap between the glass and the window frame, the hardness is great, and the smooth installation of the window sash assembly is not facilitated.
