The specific embodiment
Below in conjunction with example be accompanying drawing the utility model is described in further detail, but be not limited to following described content.
The utility model provides a kind of little rigid frame that contains steel stamping part, to overcome vertical impression that prior art exists and tie point is many and without deficiencies such as horizontal convex epireliefs.
The structure of described little rigid frame as shown in Figure 1, consists of two chord members 1 and a plurality of steel stamping part 2 and tie point 3, and wherein: two chord members 1 separation upper and lowers, it is upper and lower chord member.Upper and lower chord member is connected as a single entity by a plurality of steel stamping parts 2 and tie point 3.Described tie point 3 is the position that top-bottom chord is corresponding with the hole of stamping parts 2.
Two chord members 1 and steel stamping part 2 can perforates in tie point 3 places, utilize bolt and pulling rivet to connect upper and lower chord member and steel stamping part 2 by perforate; Or only perforate on steel stamping part 2, utilize self-tapping screw to connect upper and lower chord member 1 and steel stamping part 2 by perforate.Also can not perforate, at tie point 3 places, directly by the upper and lower chord member 1 of bonding point electrode holder, with steel stamping part 2, weld together.
Described chord member 1 side of being (square) type pipe, C shaped steel, angle steel, cap steel or Z steel cross section, the steel sheet clod wash that can be 0.6-3mm by thickness or direct hot rolling form, and can be straight line or shaped form.
The steel sheet that described steel stamping part 2 is 0.6mm-3.0mm by thickness is stamped to form, and can need to be arranged in a side of top-bottom chord according to design, as shown in Figure 2, also can be separately positioned on the both sides of top-bottom chord, as shown in Figure 3.
Be distributed with vertical convex epirelief 4, arc convex epirelief 5 and horizontal convex epirelief 6 on described steel stamping part 2, to increase the stable bearing capacity of web.In addition, the both sides of steel stamping part 2 also are provided with vertical straight line flange 7, circular arc flange 8 and oblique straight line flange 9.Three tie points 3 are arranged on each steel stamping part 2, be distributed in the both sides of arc convex epirelief 5.
According to the distribution mode difference of vertical convex epirelief 4, arc convex epirelief 5 and horizontal convex epirelief 6, the utility model has been announced the implementation of six kinds of steel stamping parts 2, and the also corresponding technical scheme that six kinds of little rigid frames are provided is specific as follows:
The first steel stamping part is 2a, is distributed with two vertical convex epireliefs 4 parallel to each other on it, and its two ends extend to the chord member inward flange.In the chord member inward flange outside, be two arc convex epireliefs 5 that outwards stretch.
The second steel stamping part is 2b, is on the basis of the first stamping parts 2a, at the together horizontal convex epirelief 6 of central authorities' increase of two vertical convex epireliefs 4.
The third steel stamping part is 2c, is on the basis of the first stamping parts 2a, the symmetrical horizontal convex epirelief 6 of twice that increases between two vertical convex epireliefs 4.
The 4th kind of steel stamping part is 2d, is distributed with two vertical convex epireliefs 4 parallel to each other on it, and its two ends extend to the chord member inward flange.Outside the chord member inward flange, be two arc convex epireliefs 5 that inwardly stretch.
The 5th kind of steel stamping part is 2e, is on the basis of the 4th kind of stamping parts 2d, at the together horizontal convex epirelief 6 of central authorities' increase of two vertical convex epireliefs 4.
