The number of the middle sub-crossbeams 1330 is one or more, when the number of the middle sub-crossbeams 1330 is one, one middle sub-crossbeam 1330 is horizontally arranged and fixedly connected with the first sub-crossbeam 1310 and the second sub-crossbeam 1320, and when the number of the middle sub-crossbeams 1330 is more, the middle sub-crossbeams 1330 are horizontally arranged and fixedly connected with the first sub-crossbeam 1310 and the second sub-crossbeam 1320 after being connected end to end.

With continued reference to fig. 2, in the present embodiment, the ratio of the maximum arch height H of the beam 1300 to the span L of the beam 1300 ranges from one-five to one-three percent, such as one-five, four, or three percent. Wherein, during the design, the size of the first included angle 10 and the second included angle 20 can be adjusted to make the ratio of the maximum arch height H to the span L within a preset range.

In this embodiment, the first flange 1420 has a uniform thickness, i.e. two opposite plate surfaces are disposed in parallel, and the fixing mounting surfaces of the first support 1100 and the second support 1200, i.e. the second flange 1120 is disposed away from the third flange 1121 of the support column 1110, referring to fig. 3, 4 and 9, fig. 9 is an exploded view of the structure of fig. 3, and the first flange 1400 is fixed on the third flange 1121 of the second flange 1120 by an adjusting plate, wherein for the sake of distinction, the adjusting plate between the cross beam 1300 and the first support 1100 is defined as a first adjusting plate 1500, and the adjusting plate between the cross beam 1300 and the second support 1200 is defined as a second adjusting plate 1600. Referring to fig. 2, 10 and 11, fig. 10 is a simplified schematic diagram of the first adjustment plate 1500, fig. 11 is a simplified schematic diagram of the second adjustment plate 1600, the thickness of the first adjustment plate 1500 gradually increases along a direction approaching the middle sub-cross-beam 1330, and a third included angle 30 between two plate surfaces of the first adjustment plate 1500 is equal to the first included angle 10; the thickness of the second adjusting plate 1600 gradually increases along the direction approaching the middle sub-cross-beam 1330, and the fourth included angle 40 between the two plate surfaces is equal to the second included angle 20. Specifically, by arranging the thicknesses of the first adjustment plate 1500 and the second adjustment plate 1600 to gradually increase along the direction approaching the middle sub-beam 1330, the first sub-beam 1310 and the second sub-beam 1320 are gradually lifted upwards, and finally the entire beam 1300 becomes an arched beam. It is understood that when the first angle 10 and the second angle 20 are equal in size, the third angle 30 and the fourth angle 40 are also equal in size. In an application scenario, the first adjustment plate 1500 may be a whole plate or may include a plurality of sub-adjustment plates stacked in layers, for example, in the application scenario of fig. 10, the first adjustment plate 1500 includes a first sub-adjustment plate 1510 and a second sub-adjustment plate 1520 stacked in layers, a connection manner between the first sub-adjustment plate 1510 and the second sub-adjustment plate 1520 may be welding or bolting, and the second adjustment plate 1600 is similar to the first adjustment plate 1500 in structure, which is not described herein again.

In an application scenario, the first flange 1400, the first adjustment plate 1500 and the first support 1100 are independent of each other, and the connection manner between the first flange 1400, the first adjustment plate 1500 and the first support 1100 may be welding or bolting. When the bolts are used for connection, as shown in fig. 9, the first adjustment plate 1500 is provided with third mounting holes 1530, the positions of the third mounting holes 1530 correspond to the positions of the first mounting holes 1423 of the first flange 1420 and the positions of the second mounting holes 1123 of the second flange 1120, and when the flange is assembled, the first flange 1400, the first adjustment plate 1500 and the first support 1100 are fixedly connected by sequentially passing the bolts through the first mounting holes 1423, the third mounting holes 1510 and the second mounting holes 1123 of the second flange 1120. In another application scenario, when the first adjustment plate 1500 is a unitary plate, the first adjustment plate 1500 may be integrated on the first flange 1400, and as shown in fig. 12, two opposite plate surfaces of the first flange 1420 are disposed non-parallel, and the thickness of the first flange 1420 gradually increases along a direction approaching the middle sub-beam (not shown), similarly, the first adjustment plate 1500 may also be integrated on the first support 1200.

It should be noted that integrating the first adjusting plate 1150 on the first flange 1400 and/or the first support 1100 can reduce the number of elements in the power transformation frame 1000, reduce the number of joint surfaces between the elements in the power transformation frame 1000, prevent the cross beam 1300 and the first support 1100 from being broken under a stress, and ensure the connection strength between the cross beam 1300 and the first support 1100.

It should be noted that the connection manner between the cross beam 1300 and the second support 1200 is the same as the connection manner between the cross beam 1300 and the first support 1100, and the description thereof is omitted.
