Description
Technical field
The utility model relates to doors and windows sealing spare, relates in particular to the weather strip for the steel door and window.
Background technology
The steel door window setting technique is widely used, and is treated coldly in China in developed country's development rapidly, and key issue is that old steel casement door window inferior causes inveteracy harmful effect to people.Twentieth century is before the eighties, the steel door and window is dominate in China's metal door and window, and after the eighties, along with progressively going deep into of reform and opening-up, Chinese national economy obtains fast development, scientific and technological level improves constantly, people begin to think the steel door and window because cross section structure is simple, intensity is low, do not have seal approach, leak out gas leakage, thermal transmittance greatly, be not incubated, the line density height, should not use at highrise building, and dividing the steel door and window into low grade, doors and windows inferior, the steel door and window is replaced by plastic window and aluminum window gradually.
Yet we think whether above-mentioned cognition correctly is to be worth discussion.When carrying out strength check, often use mechanics of materials formula: [σ]≤M/W, wherein: [σ] is the bending resistance allowable stress of material; M is the moment of flexure that acts on the main stress member; W is the opposing distance of material section; Again: W=Iz/Yz, wherein: Iz is the principal moments of inertia in section bar cross section; Yz is that the section bar section type heart is apart from the maximum value of principal moments of inertia direction of principal axis and two distances of outer surface.The allowable stress of steel is [σ]=210; The allowable stress of aluminium alloys is [σ]=70, just in time is three times poor.Because [σ] and Iz are linear, when moment of flexure one timing that acts on the main stress member, the principal moments of inertia in steel section bar cross section only needs 1/3rd of aluminium alloy extrusions; Experimental results show that by equal strength: two kinds of section bar outer profile sizes equate that the wall thickness of steel rectangular tube is 1/3rd of aluminium alloys, and the Iz value of aluminum rectangular tube only is 2.7 times of steel rectangular tube, and intensity is lower than the steel rectangular tube, and both line densities are approximate; If adopt the color steel sheet rectangular tube, price only is that three minutes of aluminium alloys are to one, take all factors into consideration, select for use steel matter rectangular tube under equal physical property condition its cost far below the aluminum alloy material rectangular tube, even adopt AISI304 stainless steel tube (price is 30.5 yuan/kilogram), though price is a little more than aluminium alloys, but its class is self-evident, this routine steel pipe weight ratio aluminum pipe weighs 9%, but steel strength is higher by 10% than aluminum pipe, therefore, the prejudice spin that does not have " steel are heavy, should not use at highrise building ".
China's iron ore deposit is abundant, is the big country that steel are produced, owing to use quantity not sufficient, every year is all in limited-quantity production; And bauxite resource lacks, all want a large amount of imports every year, price height, instability, and adopt the power consumption of 1 ton of aluminium of electrolysis legal system to be about the 13000-15000 degree, and the power consumption of making 1 ton of steel is only about 800 degree, and visible aluminium prepares energy consumption and is far longer than steel and prepares energy consumption.Therefore, if the high-grade steel door and window of energy output, its overall merit should be not less than alumium alloy door and window, and market prospects are good, and energy-conserving and environment-protective are had great, profound significance.
At present, the key problem in technology of high-grade steel door and window is that heat-insulating bridge-cut-off is difficult to form between framework and the fan body.Aluminium extruded sections becomes more readily available accurate section configuration by hot melt, extrusion process, and the aluminium elastic deformation is less, realizes aluminium alloys bridge cut-off interlock technology easily, so its easier formation heat-insulating bridge-cut-off composite construction; And the hot melt of steel, the extruding cost too high, be not suitable for adopting the moulding process identical with aluminium extruded sections, can't form accurate seal mounting structure, and the steel elastic deformation is bigger, be difficult to realize the interlock technology as the aluminium alloys bridge cut-off, therefore, the steel door and window heat-insulating bridge-cut-off be difficult to form, can't reach the high-end environmental requirement of heat-insulation and heat-preservation.
