Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
embodiment 1
As shown in Figures 1 to 3, present embodiments provide a kind of combined type beam being in length and breadth applied to Business Line fixed track usage plan, four i iron are fastened as a whole by this combined type cross beam side by side, cavity is configured with between the web of adjacent i iron, further, i iron web is evenly provided with three groups of bolts hole along i iron length direction, the bolt hole one_to_one corresponding at all i iron web places, the effect of bolt hole is for installing punching panel and screw rod, specifically, connected through after four i iron by screw rod between two relative punching panels 2, thus, in transverse direction, four i iron are carried out connection fastening.Punching panel adopts 20mm thick, and the steel plate of 400mm*400mm processes, and on punching panel, reserved 4 apertures are the hole of 24mm, and preformed hole is for installing screw rod, and preferably, screw rod is high-strength screw rod.During application, by combined type in length and breadth erection on supporting pile, then track is arranged on combined type in length and breadth on beam, realizes Business Line fixed track usage plan thus.
Further, the present embodiment is also provided with the straight buckle 3 for fastening four i iron on the end face of i iron about 1 two wing plate, and straight buckle is arranged along the width of i iron, and its total length should slightly larger than the horizontal overall width of four i iron.Straight buckle adopts 20mm thick, and the steel plate of 910mm*150mm processes.Buckle width 150mm, long 910mm, the bolt hole that diameter is 24mm is reserved at two ends, wales four i iron after upper and lower two straight buckles 3 are fastenedly connected by reinforcing screw rod 4.
In order to improve fastening effect further, the present embodiment is also also socketed with crossbeam anchor ear outside four i iron 1.
Between adjacent i iron, there is cavity clearance, the present embodiment is provided with note mud hole 6 on the wing plate of i iron, by web from note mud hole to adjacent i iron between be marked with cement in the cavity that forms, in order to reinforce the connection of adjacent i iron after theing cement solidifies, this technological means is better than welding manner, it is more conducive to the recycling of i iron, saving resource.
In the present embodiment, the web of i iron is thinner than wing plate, its role is to, and being the inertia modulus in order to increase i iron, saving firm material.
Further, the present embodiment is connected with between the web and wing plate of i iron strengthens gusset 5, make overall tension, resistance to compression, shearing resistance function obtain balanced performance.
embodiment 2
As shown in Figure 4, the difference of the present embodiment and embodiment 1 is, the web of i iron 1 has two pieces and is parallel to each other, and is provided with " X " type brace summer 7 between two blocks of webs, and four end points of " X " type brace summer 7 overlap with the four points of connection of wing plate with i iron web respectively.It is compared to common i iron, and its strength of bearing is stronger, and structure is very simple, and cost is the advantage such as relatively low also.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
