Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in Fig. 4 ~ 9, described steel frame connecting, the rectangular steel plates being 0.6mm ~ 3.0mm by thickness is stamped to form, and forms convex epirelief 12, connecting hole/3 and flange 13 through punching press, and punching is fallen corner and become circular arc trimming 10.
Described convex epirelief comprises a pair longitudinal convex epirelief 4 arranged in pairs, and a pair arc convex epirelief 5 that described longitudinal convex epirelief two ends connect, and a pair longitudinal convex epirelief is connected for annular one week with a pair arc convex epirelief.Fig. 4,5 is an only annular convex epirelief connected into by longitudinal convex epirelief of a pair straight line and the arc convex epirelief of a pair semi-circular shape, and in Fig. 4,5, annular convex epirelief is symmetrical arranged.Fig. 6,7 be Fig. 4,5 annular convex epirelief basis on, intermediate lateral adds a horizontal convex epirelief 6, Fig. 8,9 on the basis of annular convex epirelief, adds the horizontal convex epirelief 6 of twice at middle part.Horizontal convex epirelief in Fig. 6 ~ 9 is symmetrical arranged.
As shown in Fig. 4 ~ 9, described flange 13 is located at the connector edge of described a pair longitudinal convex epirelief both sides; Described flange and described connector plane orthogonal.Described flange is longitudinally symmetricly set in the both sides of connector, from Fig. 4, Fig. 6, Fig. 8, often locate flange to be connected described connector edge by the circular arc flange 8 at longitudinal straight line flange 7 at middle part, longitudinal straight line flange two ends oblique straight line flange 9 with circular arc flange outer end and form.Horizontal convex epirelief can strengthen the intensity of the anti-laterally bending of connector greatly, the intensity that the resisting longitudinal that longitudinal flange greatly can strengthen connector bends.
Especially, the convex epirelief connecting into annular significantly can strengthen the bending ability of opposing all directions and intensity.
Described connecting hole is arranged near longitudinal two edges of connector in pairs, the longitudinal edge 5mm ~ 20mm of distance join part.The distribution of described connecting hole/3 relative to the longitudinal centre line of described connector and cross central line symmetrical, make connector all have good bonding strength in all directions.
A described connecting hole/part is distributed in inside the circular arc of described arc convex epirelief 5, and remainder is distributed in outside the circular arc of described arc convex epirelief 5.Especially, described connecting hole/3 are only provided with 6, be respectively provided with one, be respectively provided with 2 outside circular arc inside the circular arc of longitudinal both sides.6 connecting holes/some quantity of attended operation is greatly reduced, thus make labour intensity and operating efficiency be significantly improved.
The inside and outside both sides of connecting hole/to be distributed in arc convex epirelief for the bonding strength of connector, have and strengthen effect significantly for being only distributed in the side of arc convex epirelief, and the bend resistance performance between making by securing member obtains the reinforcement of convex epirelief and significantly increases.
A kind of steelframe applied above-mentioned steel frame connecting and connect, as shown in Figure 1, 2, 3, comprise a pair steelframe chord member 1, and fixed span is connected to multiple steel frame connectings 2 of described a pair steelframe chord member, described steel frame connecting is fixedly connected with steelframe chord member by connecting hole/3 that it is arranged, and as Fig. 2, described steel frame connecting is fixedly connected on the side of described a pair steelframe chord member, as Fig. 3, described steel frame connecting is fixedly connected on the bilateral of described a pair steelframe chord member.The strength ratio that bilateral is fixedly connected with is one-sided is connected with significant increase, and one-sided being fastenedly connected is applicable to be unsuitable for or the connection of inconvenient bilateral, or uses one-sided connection to be enough to the situation of guaranteed strength.
Usually, the length direction of described steelframe chord member is linear, and described steelframe chord member is square tube or one of C-type steel, angle steel, cap steel, Z-shape steel, for the steel sheet of thickness 0.6mm ~ 3mm or composite material are become by clod wash or hdr.Steelframe top-bottom chord can adopt composite material to be made, thus greatly reduces the coefficient of thermal conductivity of rod member, adds the heat-insulating property of body of wall.
Especially, the length direction not getting rid of described steelframe chord member is shaped form.When the length direction of steelframe chord member is shaped form, can arrange according to the actual conditions of job site, thus make the scope of application of the present utility model be expanded, for shaping lightgage steel joist system, the utility model has the flexibility advantage of its uniqueness.
