Abstract
The utility model discloses a door and window mullion profile, which comprises an upper rectangular pipe and a lower rectangular pipe, wherein the left end and the right end of the bottom surface of the lower rectangular pipe respectively extend outwards, the upper part of each of extending plates of the left end and the right end of the lower rectangular pipe is respectively provided with a slide groove and a sealing strip embedding groove, the upper surface of the upper rectangular pipe respectively extends to the left end and the right end, the tail ends of extending plates of the left end and the right end of the upper rectangular pipe are respectively bent downwards to form clamping grooves, the side edges of the upper end of the lower rectangular pipe are provided with reinforcing ribs, the adjacent surfaces of the upper rectangular pipe and the lower rectangular pipe are respectively provided with concave grooves, and the upper rectangular pipe and the lower rectangular pipe are connected into a whole by heat insulation strips which are clamped in the concave grooves. The door and window mullion profile has the advantages that the upper rectangular pipe and the lower rectangular pipe are adopted and are connected into a whole by the lengthened and reinforced heat insulation strips, so the mechanical strength is ensured, the cold air and hot air are effectively isolated, and the energy saving performance and waterproof performance are improved; the side edges are provided with the reinforcing ribs, so the strength is increased.
Description
Technical field:
The utility model relates to the aluminium extruded sections field, is specifically related to a kind of sash bar section bar.
Background technology:
Aluminium alloys is a most widely used class non-ferrous metal structural meterials in the industry, widely applies in Aeronautics and Astronautics, automobile, machine-building, boats and ships and chemical industry.Along with the in recent years develop rapidly of science and technology and industrial economy, increasing to the demand of Welded structural member, make the Research on Weldability of aluminium alloys also thereupon deeply.Along with growth in the living standard, the highrise building of some middle and high ends and comfortable house have higher demand with aluminium alloys to its performance and surperficial quality, at present, popular aluminium door frame and door leaf on the market, exquisite appearance is difficult for getting rusty, but the cavity of the thermal insulation barriers that adopts is little, the large percentage that causes aluminium to account in integral material so that the price of aluminium increases, has increased the cost of material greatly; Because it is lightweight that aluminium extruded sections has, anti-put forth effort strong advantage and be widely used on the building, but not sound insulation of aluminium extruded sections, insulation and anti-seismic performance inequality and cost are higher; And the existing door sash bar section bar coefficient of expansion is larger, is prone to the phenomenon of splitting glue after erection of doors and windows is good, and antiseep is poor, and decay resistance is bad, and the maintenance expense is high, and insulating properties is bad, and damping performance is bad, and watertightness is bad.
The utility model content:
The utility model provides a kind of and gains in strength, improves insulation and anti-seismic performance, and the door sash bar section bar that conveniently installs and fixes.
The utility model technical solution problem provides following scheme:
A kind of sash bar section bar, comprise upper and lower two rectangular pipes: the two ends, the left and right sides of the bottom surface of described lower rectangular pipe stretch out respectively, and the extension board at two ends top is provided with chute and weather strip embedding groove, the upper surface of described upper rectangular pipe is to the left and right two ends extension respectively, and the end of two ends extension board all is bent to form draw-in groove downwards; Described lower rectangular pipe upper end side is provided with reinforcing rib; Have respectively groove on the adjacent face of described upper and lower two rectangular pipes, described upper and lower two rectangular pipes are by being connected to connecting as one every holding bar in the groove.
Have respectively groove on the adjacent face of described upper and lower two rectangular pipes, described upper and lower two rectangular pipes by be connected in the groove about two connect as one every holding bar.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the structure of upper and lower rectangular pipe, and by lengthening connecting as one every holding bar of strengthening, when guaranteeing mechanical strength, effectively isolated cold and hot air improves energy-efficient performance and water resistance; And at side reinforcing rib is set, gain in strength.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
A kind of sash bar section bar, comprise upper and lower two rectangular pipes 1,2: the two ends, the left and right sides of the bottom surface 3 of lower rectangular pipe 2 stretch out respectively, and the extension board at two ends top is provided with chute 4 and weather strip embedding groove 5, the respectively to the left and right two ends extension of the upper surface 6 of upper rectangular pipe 1, and the end of two ends extension board all is bent to form draw-in groove 7 downwards; Lower rectangular pipe 2 upper end sides are provided with reinforcing rib 8; Have respectively groove on the adjacent face of upper and lower two rectangular pipes, upper and lower two rectangular pipes by be connected in the groove about two connect as one every holding bar 9.
Above-described embodiment only is better embodiment of the present utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
