Abstract
The utility model relates to a isosceles triangle honeycomb main longitudinal girder for a bridge erecting machine. An isosceles triangle supporting rack is composed of an upper chord rod, a lower chord rod and two ventral plates, wherein, honeycomb pores are arranged on the ventral plates. A steel rail is arranged over the upper chord rod. Both ends of the upper chord rod and the lower chord rod are respectively provided with a mother core plate and a male core plate. A connecting pin is arranged on the mother core plate. A vertical supporter and a sloping supporter are arranged on the lower chord rod. Inner partition plates are arranged at intervals in a length direction on the ventral plate. The utility model has the advantages of unique and novel structure, convenient and rapid installation and operation, great rigidity, high stability, high safety, and wide application range.
Description
The utility model relates to the isosceles triangle honeycomb fashion main longitudinal grider that a kind of machine of building bridge uses.
Main longitudinal grider is a bridge formation machine capital equipment (parts).Existing bridge formation machine main longitudinal grider is generally real abdomen or the box and girder truss structure of empty stomach, real abdomen or empty stomach box beam weight are big, and end face is a quadrangle, and wind area is big, unstable in the construction, work high above the ground is dangerous, though girder truss alleviates to some extent than solid web girder weight, wind area diminishes, but aspect of performance rigidity fails to improve, globality descends to some extent, and it is dangerous to construct, and quality can not get effective assurance.
The purpose of this utility model is the problem that exists at existing bridge formation machine main longitudinal grider, and a kind of novel isosceles triangle honeycomb fashion main longitudinal grider is provided, to solve the problem of main longitudinal grider body weight rigidity difference.
The purpose of this utility model is achieved like this, main longitudinal grider isosceles triangle cellular structure, and promptly end face is an isosceles triangle, on the two deviational survey webs honeycomb hole is arranged, and there is chord member top and the bottom, and there is connecting pin the joint.
The utility model novel structure, uniqueness, easy to install, economical with materials, wind area is little, and is safe and reliable, improved the overall performance of bridge formation machine greatly, and wide application has remarkable social benefit and economic benefit.
Below in conjunction with accompanying drawing structure of the present utility model is elaborated.
Fig. 1 is an isosceles triangle honeycomb fashion main longitudinal grider upward view;
Fig. 2 is an isosceles triangle honeycomb fashion main longitudinal grider front view;
Fig. 3 is an isosceles triangle honeycomb fashion main longitudinal grider end face A-A sectional view.
By Fig. 1, Fig. 2 provides, the utility model is to constitute isosceles triangle by two skew back webs 5 with the upper chord 3 on top, tiltedly web 5 bottoms are contained on the lower chord 6, perpendicular support 9 of underframe and underframe diagonal brace 10 are housed between lower chord, make upper chord 3, two oblique webs 5 and two lower chords 6 constitute stable isosceles triangle bracing frame, tiltedly on the web 5 honeycomb hole 14 is arranged, two oblique web 5 length directions are equipped with internal partition with holes 4 at interval, three faces of isosceles triangle are bound up, be fixed with rail 16 directly over the upper chord 3, the upper chord 3 one ends public central layer 1 that winds up, the body core plate 12 that winds up on the other end, lower chord 6 one ends have the public central layer 7 of lower edge, and the other end has lower edge body core plate 11, the coupling pin 17 that winds up on the body core plate 12 that winds up has lower edge coupling pin 18 on the lower edge body core plate 12; For reinforcing, stiffener 2 is equipped with in public central layer 1 both sides of winding up, and stiffener 8 is equipped with in the public central layer of lower edge 7 both sides; For improving integral rigidity and section modulus, gusset 15 is arranged on the upper chord 3, tiltedly there is gusset 13 web 5 inboards.
The whole section of the utility model main longitudinal grider is isosceles triangle (seeing shown in Figure 3), on coxostermum and the internal partition honeycomb hole is arranged, thereby makes whole main longitudinal grider be the isosceles triangle cellular structure, and its material is made by shaped steel and steel plate.The oblique web 5 of its two waist can be cut open along set broken line by certain thick steel plate, and dislocation is welded to each other and forms then.The bottom surface is a parallel chords framework, perpendicular support 9 of the lower chord 6 of framework and underframe and underframe diagonal brace 10 are made up of i iron or channel-section steel, lower chord 6 pins down two skew back webs 5 securely, the section that upper chord 3 also is made up of i iron or channel-section steel, two skew back webs, 5 center lines are by upper chord 3 section center of gravity line, because of its length direction is arranged internal partition 4 at regular intervals, three faces of isosceles triangle are bound up, stressed jointly, strengthen stiffness and prevent oblique web 5 unstabilitys, gusset 15 is set on upper chord 3 in addition, is provided with gusset 13, improved integral rigidity and section modulus more in oblique web 5 inboards.
During installation, whenever set a roof beam in place and beam between be 1 pair of the public central layer that the winds up body core plate 12 that winds up, 7 pairs of lower edge body cores of the public central layer of lower edge plate 11 links together by wind up coupling pin 17 and lower edge coupling pin 18 then, finish the assembling of whole main longitudinal grider, the hanging beam trolley travelling on the bridge formation machine is in rail 16 tops.
The utility model is compared with existing Bridge Erector main longitudinal grider, has obvious advantage and good effect, From heavy and light, can save steel 20～30%, bearing capacity is big, and rigidity and section modulus improve 20～25%, end face is isosceles triangle, and the honeycombed hole of both sides is not only attractive in appearance but also be convenient to install Pipeline and cable, what is more important has greatly reduced wind area, has increased the safety of work high above the ground The property. The joint adopts bearing pin to connect without exception, and dismounting is very simple and efficient, adaptation Bridge Erector flowability Characteristics are can it is nearly 40% to save dismounting and freight, though this utility model and girder truss contrast are heavy Amount slightly has increase, but rigidity improves 40%, and globality and security also are greatly improved. This reality With novel be a member that applicability is very strong, also can be applicable on other the equipment, such as the gate-type lifting Machine crossbeams etc., it is applied to build for building bridge and makes creative contribution.
