| 1、U型槽口的五金设计原理：U型槽口(五金)在欧洲是针对塑料门窗和木门窗的专用五金槽口，U型槽口的五金连接方式采用自攻螺钉螺接的方式安装五金件。但是如果应用在铝合金门窗上，当安装U槽五金用的自攻螺钉承载由门窗开关所产生的纵向剪切力时，由于自攻钉的硬度远远大于铝合金型材，自攻钉的螺扣就会对铝合金型材产生破坏，造成安装孔扩大，长此以往五金件的螺钉连接就会出现脱扣。由于塑钢门窗的内衬为钢才，材料硬度与自攻钉相等不会发生安装孔扩大和五金件脱扣现象。由于U型槽口(五金)应用在铝合金门窗上不符合机械设计中的机械材料等强设计原理，出于对门窗五金安全性的考虑，欧洲铝合金门窗不采用U型槽口(五金)。 1. Hardware design principle of U-groove: U-groove (hardware) is a special metal groove for plastic doors and windows and wooden doors and windows in Europe. The hardware connection mode of U-groove adopts self-tapping screw to install hardware. But if it is applied to aluminum alloy doors and windows, when the self-tapping screws used for installing U-slot hardware bear the longitudinal shear force produced by the door and window switch, because the hardness of self-tapping screws is far greater than that of aluminum alloy profiles, the self-tapping screws will destroy the aluminum alloy profiles, resulting in the expansion of installation holes, as long as the previous hardware screws. The connection will be tripped. Because the lining of plastic steel doors and windows is steel, the hardness of the material is equal to that of self-tapping nails, and the enlargement of the mounting hole and the release of the hardware will not occur. U-notch (hardware) is not suitable for aluminum alloy doors and windows because it does not conform to the design principle of mechanical materials in mechanical design. For the sake of hardware safety of doors and windows, U-notch (hardware) is not used in European aluminum alloy doors and windows. 2、U型槽口的五金导致铝合金门窗腐蚀渗水：U型槽口五金的材质只要为钢，当五金件通过钢制自攻钉连接到铝型材上当受到雨水和潮湿空气的侵蚀时会发生较明显的化学反应(俗话说的结碱现象)影响门窗的使用，破坏门窗的防水构造。 2. The hardware of U-notch causes the corrosion and seepage of aluminum alloy doors and windows: As long as the material of U-notch hardware is steel, when the hardware is connected to aluminum profiles by steel tapping pins, when it is eroded by rain and humid air, there will be obvious chemical reactions (as the saying goes alkaline phenomenon) affecting the use of doors and windows, destroying the waterproof of doors and windows. Structure. 3、C型槽口五金设计原理先进：C型槽口五金安装是依靠不锈钢钉顶紧力和机螺钉不锈钢衬片与五金槽口夹紧力来保障五金件的安装牢固度，不锈钢钉顶紧会在型材表面产生约0.5～1.0毫米的局部变形使不锈钢钉与铝型材紧密的结合在一起保障五金件在受力时不发生位移。 3. C-groove hardware design principle is advanced: C-groove hardware installation relies on stainless steel nail top tightening force and machine screw stainless steel lining and metal groove clamping force to ensure the installation of hardware firmness, stainless steel nail top tightening will produce about 0.5-1.0 mm local deformation on the surface of profiles so that stainless steel nails and aluminum profiles tightly knot. Together, the hardware must be protected from displacement. 4、C型槽口五金安装方便：不用打安装孔，不采用自攻钉连接，安装简便，对设备等(电、气)辅助条件的依赖低，可以实现现场安装。 4. C-groove hardware installation is convenient: no need to punch the installation hole, do not use self-tapping nail connection, easy installation, low dependence on equipment (electricity, gas) auxiliary conditions, can achieve on-site installation. 5、材质对比：C型槽口五金是专用的铝合金(金属)门窗五金，而U型槽口五金源于塑料门窗，从材质的要求到五金杆件的硬度要求都要低于C型槽口五金。例如：C型槽口五金的五金材质主要为挤出铝、锌基压铸合金、炭氮共渗钢、不锈钢、二硫化钼尼龙，表面处理为达克罗表面处理、RAL表面彩色喷涂(与法拉利底盘防腐处理相同)，经过严格的耐腐蚀试验，不会发生结碱现象。 5. Material comparison: C-slot metal is a special aluminum alloy (metal) door and window hardware, and U-slot metal comes from plastic doors and windows, from the material requirements to the hardness of hardware rods are lower than C-slot metal. For example: C-slot metal material is mainly extruded aluminum, zinc-based die-casting alloy, carbonitriding steel, stainless steel, molybdenum disulfide nylon, surface treatment for Dacromet surface treatment, RAL surface color spraying (the same as Ferrari chassis corrosion treatment), after strict corrosion resistance test, will not occur caustic phenomenon. 6、C型槽口五金的连接构造安全性：C型槽口铰链采用高硬度的不锈钢衬片(该衬片采用特殊的构造)，在紧固螺钉拧紧时衬片上的特殊构造将像牙齿一样咬入铝合金型材的表面，形成若干0.2～0.5mm的局部变形(小坑)，从而保证了窗扇的安全性能，杜绝由连接螺钉与铝型材硬度不等产生脱扣而出现平开窗(门)的窗(门)扇脱落现象。 6. Safety of connection structure of C-groove hardware: C-groove hinge adopts stainless steel lining with high hardness (this lining adopts special structure). When fastening screws are tightened, the special structure of the lining will bite into the surface of aluminum alloy profiles like teeth, forming a number of 0.2-0.5mm local deformation (pits), thus guaranteeing the window. The safety performance of the fan prevents the window (door) of the flat window (door) from falling off because of the unequal hardness between the connecting screw and the aluminum profile. |
