Abstract
The utility model relates to the technical field of a crane span structure, in particular to a side edge connecting piece of a grid crane span structure. The side edge connecting piece of the grid crane span structure is used for connection of the position of a U-shaped arm of two grid type U-shaped crane span structures. The grid crane span structure is a plain sheet grid body formed by transverse bars and longitudinal bars. The plain sheet grid body is bent to form a groove with a U-shaped cross section. The transverse bars in touch with the position of the lap joint of the two grid type U-shaped crane span structures are first transverse bars. The transverse bars of the two grid type U-shaped crane span structures adjacent to the first transverse bars are second transverse bars. The side edge connecting piece of the grid crane span structure is provided with clamp grooves used for clamping the first transverse bars of the two grid type U-shaped crane span structures. Two bar press grooves with different directions are arranged on the upper side of the connecting piece. The two bar press grooves are used for clamping the longitudinal bars in a same straight line of the two grid type U-shaped crane span structures. Two ends of the connecting piece are respectively provided with a transverse bar press groove fixed on the second transverse bars. The side edge connecting piece of the grid crane span structure is simple in structure, quick and simple in disassembly and assembly, quite short in disassembling and assembling time, high in working efficiency and strong in integral stability and safety of the crane span structure.
Description
Technical field
The utility model relates to the technical field of crane span structure, especially a kind of side edge connecting part of grid crane span structure.
Background technique
Connection between original crane span structure is all to be fixing by link usually, link is welded on the both sides of adjacent crane span structure, and there is following shortcoming in this fixed structure: arbitrarily dismounting bumps or when shaking, cause easily loosening, stability and Security relatively poor.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of side edge connecting part of grid crane span structure is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of side edge connecting part of grid crane span structure, be used between two latticed U-shaped crane span structures the connection at U-shaped arm place, the plain film grid body that this crane span structure is comprised of horizontal bar and vertical muscle, being converted into cross section by plain film grid body again is U-shaped groove shape, be the first horizontal bar at two contacted horizontal bars of latticed U-shaped crane span structure lap-joint, two latticed U-shaped crane span structure horizontal bars adjacent with the first horizontal bar are the second horizontal bar, described link is provided with the draw-in groove that blocks the first horizontal bar on two latticed U-shaped crane span structures, be provided with the rib-pressing groove of the opposite direction of the vertical muscle of two latticed U-shaped crane span structures of two buckles on same straight line at the upside of link, the two ends of link respectively are provided with a horizontal bar indent that is fixed on the second horizontal bar.
Described link is provided with increases flexible flanging.
The beneficial effects of the utility model are: the utility model the utility model is simple in structure, and dismounting is quick, easy, has greatly shortened disassembly and assembly time, has improved working efficiency, has strengthened stability and the Security of crane span structure integral body.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is use phase diagram of the present utility model.
Among the figure: 1. horizontal bar, 11. first horizontal bars, 12. second horizontal bars, 2. vertical muscle, 3. link, 31. draw-in grooves, 32. rib-pressing grooves, 33. horizontal bar indents, 34. flaps.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The side edge connecting part of grid crane span structure as shown in Figure 1, be used between two latticed U-shaped crane span structures the connection at U-shaped arm place, the plain film grid body that this crane span structure is comprised of horizontal bar 1 and vertical muscle 2, being converted into cross section by plain film grid body again is U-shaped groove shape, be the first horizontal bar 11 at two contacted horizontal bars of latticed U-shaped crane span structure lap-joint, the horizontal bar that two latticed U-shaped crane span structures are adjacent with the first horizontal bar 11 is the second horizontal bar 12, link 3 is provided with the draw-in groove 31 that blocks the first horizontal bar 11 on two latticed U-shaped crane span structures, be provided with the rib-pressing groove 32 of the opposite direction of the vertical muscle 1 of two latticed U-shaped crane span structures of two buckles on same straight line at the upside of link 3, the two ends of link 3 respectively are provided with a horizontal bar indent 33 that is fixed on the second horizontal bar 12, and link 3 is provided with increases flexible flanging 34.
During installation, one end of link 3 is put in the grid of one of them U-shaped crane span structure, two contacted the first horizontal bars 11 on draw-in groove 31 buckles on one end, rib-pressing groove 32 compresses the vertical muscle 2 of crane span structure end on same straight line, the horizontal bar indent 33 of one end is blocked the second horizontal bar 12, again the other end of link 3 is put into the grid of the U-shaped crane span structure of another one, rib-pressing groove 32 compresses the vertical muscle 2 of crane span structure end on same straight line on the other end, press 33 to block the second horizontal bar 12 horizontal bar of the other end, installment work has just been finished.
During dismounting, will dismantle first an end opposite with the opening direction of draw-in groove 31, then link for convenience detach like this pulls out the first horizontal bar 11 just passable from draw-in groove 31.
The thickness of link 3 is 1.2mm-1.5mm.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
