1, the outside window must set drainage channel, drain hole, exhaust hole (air pressure balance hole), and discharge the water in the window frame fan. On the outside of the drain, a buckle cover should be set to prevent the strong wind from blowing rain and dust into the window.
2、隔热条应采用C型构造,与内外铝型材复合后在同一个水平面上,避免隔热条处积水造成渗漏、腐蚀隐患,同时可增加隔热条长度,提高热工性能。
2, the heat insulation strip should be constructed with C structure, combined with the internal and external aluminum profiles on the same horizontal surface to avoid leakage and corrosion hazards caused by water accumulation at the insulation strip, and increase the length of the heat insulation strip and improve the thermal performance.
3、门窗洞口尺寸:结构洞口预留不应过大,避免封堵困难造成渗漏隐患。
3, the size of the opening of the door and window: the reservation of the structure hole should not be too large to avoid the hidden danger of the leakage.
4、企口:窗洞因为特殊原因,如外墙为石材幕墙,洞口预留尺寸大,结构洞口建议做企口,企口应与混凝土墙同时浇筑。
4, export enterprises: window due to special reasons, such as exterior wall stone curtain wall, the hole reserved for large size, the structure recommended groove, groove should be pouring concrete wall and at the same time.
5、外窗台板:外墙材料为涂料的建筑,建议采用金属窗台板。金属窗台板内侧应压入窗框,外侧突出墙面做滴水。
5, outside window plate: the exterior wall material is the paint of the building, it is recommended to use the metal sill board. The inside of the metal window plate should be pressed into the window frame, and the outside of the panel should be made of the wall to make dripping water.
6. 窗框与结构洞口:窗框宜立中安装,如靠外侧安装,应向内收进20mm,防止结构施工误差导致窗框安装在结构外皮以外,造成雨水渗漏。
6., window frames and structural openings: installation of window frames should be erect. If installed on the outside side, 20mm should be inward, so as to prevent structural construction errors and cause window frames to be installed outside the structural skin, causing rainwater leakage.

三、 框扇结构要求
Three, frame fan structure requirements
1、组角:组角是关系到门窗整体性的重要工序。
1, group angle: the angle of the group is an important process which is related to the integrity of the doors and windows.
2、抹胶工艺:一般情况下应采用角码+抹组角胶工艺,窗角禁止未抹胶即挤压成型。
2, gumming process: the corner + group angle glue process should be put under normal circumstances, the corner of the window do not wipe glue that is extrusion molding.
3、注胶工艺:组角亦可采用角码+导胶槽+注胶孔+双组份注胶+角片工艺,保证角部强度要求,确保门窗成品在运输、安装后无变形移位现象的出现。
3 plastic injection process: angle can be used to bracket two-component glue injection + process + Guide + glue groove angle + plastic injection hole, ensure the corner strength, make sure the doors and windows products in the transportation and installation of no deformation after shift phenomenon.

四、保温隔热要求
Four. Requirements for heat insulation and heat insulation
1、型材的腔体设计:型材应采用多腔体结构,减少热量的流失,同时应使外窗隔热构件上下共面,形成整体隔热面,消除冷桥,阻断热量流失通道。
1, section cavity design: the profile should adopt multi cavity structure to reduce heat loss, and at the same time, we should make the exterior window insulation components face up and down, form the overall heat insulation surface, eliminate the cold bridge, and block the heat loss channel.
2、玻璃安装槽内宜安装隔热胶条:增加空气腔室的数量,降低中空玻璃四周与型材之间的热量损失,提高整窗的保温效果。
2, the installation of heat insulation adhesive strips should be installed in the glass installation slot: increase the number of air chambers, reduce the heat loss between the insulating glass and the profiles, and improve the insulation effect of the entire window.
3、窗扇应采用T型隔热条设计:窗扇隔热条设计为T型,与中间胶条搭接,实现扇框连接处冷热分区。禁止将中间胶条直接搭在扇的铝型材上。
3, the window fan should adopt the T type heat insulation strip design: the window fan insulation bar is designed to be T type, and is connected with the middle glue bar to realize the cold and hot zoning of the connection of the fan frame. No intermediate strip directly on the aluminum on the fan.
4、隔热条应采用聚酰胺66(即Polyamide66,俗称尼龙66)。
4, the heat insulation strip should be polyamide 66 (Polyamide66, commonly known as nylon 66).
5、玻璃暖边条:双层中空玻璃空腔四周宜设置暖边条,阻断玻璃空腔散热通道。
5, warm glass edge: double hollow glass cavity should be set around the warm edge, blocking the glass cavity cooling channel.
6、在传热系数要求高的地域,可根据项目定位,在型材隔热腔体内增加保温隔热材料,满足K值要求。
6. In the region where the heat transfer coefficient is high, the thermal insulation material can be added to the heat insulation cavity of the profile to meet the K requirement.
7、外门:住宅首层住户通向花园的外平开门应设门槛,禁止不设门槛,门底部用毛刷封闭。住宅首层住户通向花园的双扇平开外门,关闭后两扇应咬合搭接,禁止中间留缝用毛刷封闭。
7, the door opened the door: flat first floor tenants to the garden house should set the threshold, do not set the threshold, the bottom of the door closed with a brush. The first floor of residential tenants to the garden door double flat open door, shut down after the two fan should bite the lap, middle seam with brush seal ban.

五、安全技术要求
Five. Safety technical requirements
1、玻璃扣条:玻璃扣条应安装在室内一侧,禁止将内开窗翻转成外开窗使扣条安装在室外一侧,保证防盗、安全、玻璃更换的要求,不留渗漏隐患。
1, glass buckle: Glass buckle should be installed in the indoor side. It is forbidden to turn the inside window into external window, so that the button can be installed on the outdoor side, so as to ensure the requirements of anti-theft, safety and glass replacement, without leakage risk.
2、锁点:为提高外窗抗风压强度及防盗性能,外窗应采用多点锁。锁点设置应满足五金厂家设计安装手册要求。
2, lock point: in order to improve the anti wind pressure strength and anti-theft performance of the outer window, the outer window should adopt multi point lock. The lock point setting should meet the requirements of the hardware manufacturer's design and installation manual.
3、单元入口外门尺寸不应过大,以保证合页等五金配件的可靠性,避免产生安全事故。
3, unit entrance door size should not be too large, to ensure the reliability of hinges and other hardware accessories, to avoid the occurrence of safety accidents.
