The sealing joint strip comprises a joint strip body which is formed by a hard glue portion and a soft glue portion in a connected mode, wherein the hard glue portion is used for being connected and fixed with the steel doors and windows, and the soft glue portion is used for forming seal with the steel doors and windows. The sealing joint strip for the steel doors and windows has the advantages of being simple in structure, convenient to install and reliable in sealing.
Description
Technical field
The utility model relates to doors and windows sealing spare, relates in particular to the sealing joint 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, and all wants a large amount of imports every year, price height, instability.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.
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.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy for installation, reliable sealing to be used for the sealing joint strip of steel door and window.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of sealing joint strip for the steel door and window comprises the adhesive tape body, and described adhesive tape body is by the ebonite portion that is used for being connected and fixed with described steel door and window and be used for having the flexible glue portion of the sealing of forming to connect and compose with described steel door and window.
Described flexible glue portion is provided with the elasticity press section with the side that described steel door and window contacts.
Described elasticity press section is along the outward flange setting of flexible glue portion.
The cross section of described elasticity press section is certainly the hook-shaped of bending outside to inside.
Described ebonite portion is connected by securing member with described steel door and window.
Compared with prior art, advantage of the present utility model is:
Sealing joint strip for the steel door and window of the present utility model, adopt the compound syndeton of ebonite portion and flexible glue portion combination, its making is simple, easy for installation, sealing is reliable, solve steel and be difficult for producing accurate sealing joint strip mounting groove, the problem of being inconvenient to install sealing joint strip, reached the purpose that forms heat-insulating bridge-cut-off structure between steel door and window framework and the fan body.The side that flexible glue portion contacts with the steel door and window is provided with the elasticity press section, and elastic compression portion makes that extruding flexible glue portion produced elastic deformation when door and window was closed, thereby makes sealing more tight; The elasticity press section is along the outward flange setting of flexible glue portion, the cross section of elasticity press section is certainly the hook-shaped of bending outside to inside, be hook-shaped elastic compression portion and form elastic deformation assurance sealing effectiveness easily, and the hook formation of edge of flexible glue portion has been strengthened intensity, make the flexible glue portion can be not impaired easily, prolong application life, and this hook formation certain stiction of formation between meeting and contact surface that is squeezed after the distortion, the existence of this stiction can further guarantee the reliability of sealing effectiveness.
