Description

Energy-saving window bridge-cut-off connecting piece
Technical Field
The invention relates to an energy-saving window bridge-cut-off connecting piece.
Background
The bridge-cut-off aluminum (also called thermal insulation bridge-cut-off section bar, thermal insulation bridge-cut-off aluminum section bar, thermal insulation aluminum alloy section bar, bridge-cut-off aluminum alloy, cold bridge-cut-off section bar, bridge-cut-off aluminum plastic composite section bar) on the door and window has more excellent performance than the common aluminum alloy section bar.
As shown in fig. 1, the existing bridge-cut-off aluminum comprises an outer frame aluminum alloy section a and an inner frame aluminum alloy section B, wherein the inner side surface of each section is provided with a convex latch, a left bayonet and a right bayonet are formed together, a nylon heat-insulating strip 1 can penetrate between the two opposite sections and the bayonets on the same side, a left nylon heat-insulating strip 1 and a right nylon heat-insulating strip 1 are penetrated together, and a cavity between the two nylon heat-insulating strips 1 is filled with a heat-insulating foam material 2.
The above bridge-cut aluminum has the disadvantages that: (1) under the conditions of high temperature and low temperature, the shearing resistance and the tensile strength of the nylon heat insulation strip are greatly reduced, and when the nylon heat insulation strip is used on a bridge-cut-off aluminum profile, the shearing resistance and the tensile strength of the bridge-cut-off aluminum are directly lower; (2) the heat conductivity coefficient of the nylon heat insulating strips is about 0.3W/(m.K), and the heat transfer coefficient of the bridge-cut aluminum adopting the nylon heat insulating strips in the heat insulating areas with the same width is 2.44W/(m.K). If a lower Uf value (heat transfer coefficient) is to be achieved, the width of the insulating strips needs to be widened, but the cost of the whole window is greatly increased; (3) when the nylon heat insulation strips are installed, the strips need to be threaded at least twice (such as the left heat insulation strip and the right heat insulation strip in fig. 1), and the heat insulation materials are filled, so that the cost is high, and the installation time is long.
Disclosure of Invention
The invention aims to provide the energy-saving window bridge-cut-off connecting piece which has higher tensile strength and shear strength and low heat transfer coefficient and can be assembled efficiently.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an energy-conserving window bridge cut-off is connected and is picked up, includes the thermal-insulated bridge cut-off section bar of frame, the thermal-insulated bridge cut-off section bar of inside casing, sets up on the opposite face of the thermal-insulated bridge cut-off section bar of frame, the thermal-insulated bridge cut-off section bar of inside casing and all has the latch, forms the draw-in groove between the adjacent latch, still includes the heat insulating strip that forms by the integrative manufacturing of combined material, the heat insulating strip penetrates in the draw-in groove.
The invention adopts the integrated composite material to manufacture the heat insulation strip, the tensile strength and the shear strength of the heat insulation strip are higher than those of a nylon heat insulation strip (added with the heat insulation foam material), the assembly of the bridge-cut connector can be completed only by penetrating the strip once, the assembly efficiency is improved, and the heat insulation material is saved, so that the overall production cost is lower.
Furthermore, glue injection grooves are formed in the surfaces, in contact with the outer frame heat insulation bridge-cut-off section bars and the inner frame heat insulation bridge-cut-off section bars, of the heat insulation strips. The heat insulating strip is when penetrating the draw-in groove (the strip is worn promptly to this process), adopts the injecting glue machine with the leading-in injecting glue groove of glue solution for heat insulating strip and section bar bond, can promote the fastness of structure, thereby promote the joint strength of bridge cut-off connecting piece, can realize wearing the strip in step moreover and sticky.
Further, the density of the composite material is 901-1200 Kg/m 3 The shear strength is 30-65 Mpa, the heat conduction coefficient is less than or equal to 0.1W/(m.K), and the tensile strength is 80-120 Mpa.
In terms of materials, the shear strength and the tensile strength of the composite material are both higher than those of a nylon material, and the heat conduction coefficient of the composite material is lower than that of the nylon material, so that the heat insulation performance is greatly improved, and the heat conduction coefficient of the whole door window can be reduced without increasing the area of a heat insulation strip; and because the heat-insulating foam material is saved, compared with the cost of composite materials and nylon materials, the overall cost of the bridge-cut-off aluminum adopting the composite materials is reduced by 31-49 percent.
Further, the composite material comprises rigid polyurethane foam and reinforcing fibers, and the mass part ratio of the rigid polyurethane foam to the reinforcing fibers is 1: 1-1: 2.
The inventors have found that as the fiber content increases, the strength of the composite material increases, and below 50% fiber content, the overall density of the composite material does not reach 900Kg/m 3 However, too high a fiber content may result in dry yarn, which affects the quality of the product. Therefore, the range is selected to be 1: 1-1: 2, which can ensure the high density of the material and does not influence the quality of the material.
Further, a flame retardant with a flame retardant grade of more than B1 grade (classified according to the standard of GB 8624-2012 building material and product combustion performance grade) is added into the composite material, and the mass part ratio of the composite material to the flame retardant is 10: 1-10: 4. The flame retardant does not react with the raw materials of the polyurethane foam and the reinforced fibers, so that the fireproof performance of the composite material can be improved.
Further, the reinforcing fiber is one or a mixture of several of continuous glass fiber, glass fiber felt, bamboo fiber and polymer fiber. Different fibers were selected: continuous glassGlass fiber (density 2.6 g/cm) 3 ) Continuous glass fiber mat (density 2.6 g/cm) 3 ) Bamboo fiber (1.49 g/cm) 3 ) And chemical fibers (common PP/PET spinning fibers have the density of 1.0-1.2 g/cm3), so that the composite material keeps the characteristics of high strength and high density according to different fiber densities and design dosage.
Further, the raw materials of the rigid polyurethane foam comprise a material A and a material B, wherein the mass part ratio of the material A to the material B is 1: 0.9-1: 1.2. The polyurethane foam prepared by adopting the proportion has good performance in the aspects of heat insulation, acid and alkali resistance, corrosion and moisture resistance, size stability and the like.
Further, the material B is isocyanate or modified isocyanate; the material A comprises the following raw materials in parts by mass:
