[0022] The lower end of the cast steel outer frame 1 is provided with a second support 16 on both sides, and the second support 16 is welded and fixed with the cast steel outer frame 1. The first support 11 is arranged towards the middle position of the cast steel outer frame 1. The upper end of the first support 11 is welded and fixed with the lower end of the floor 2. When adjusting the horizontal position of the floor 2, the first support 11 will be adjusted in conjunction with the second support 16;

[0023] In addition, in order to facilitate the fixation of the floor 2 and the first support 11 after the horizontal position adjustment, three third installation cavities 13 are longitudinally arranged in the interior of the two first supports 11, and three second installation cavities 12 are longitudinally arranged in the interior of the two second supports 16. The second installation cavities 12 and the third installation cavities 13 have the same caliber. After the fixed structure sequentially passes through the second installation cavities 12 and the third installation cavities 13, the fixation of the first support 11 and the floor 2 is realized, avoiding the bending and breaking of the second plug 9 and the first plug 5.

[0024] In order to facilitate the fixation of the first support 11 and the floor 2, the two sides of the floor 2 are provided with a fixed sheet 3. Five first installation cavities 4 are longitudinally arranged in the interior of the fixed sheet 3. The second plug 9 is arranged to pass through the interior of the first installation cavity 4 on one side of the floor 2. The first plug 5 is arranged to pass through the interior of the first installation cavity 4 on the other side of the floor 2. After the first plug 5 and the second plug 9 sequentially pass through the first installation cavity 4, the second installation cavity 12 and the third installation cavity 13, the fixation of the floor 2 and the first support 11 is realized.

[0025] As shown in the accompanying drawings, Figure 2 The second plug 9 is provided with an extension block 10 on the side facing the first plug 5. The extension block 10 is embedded in the interior of the first plug 5 and connected with the internal clamping groove of the first plug 5. After the second plug 9 and the first plug 5 are inserted into the interior, the extension block 10 will be embedded in the interior of the first plug 5 to reinforce the entire slot type cast steel structure. At the same time, after the second plug 9 and the first plug 5 are inserted and supported, the bending and breaking of the second plug 9 and the first plug 5 is avoided.

[0026] In order to fix the first plug 5 and the second plug 9 inserted into the interior of the slot type cast steel, the first installation hole 8 is arranged on both sides of the first installation cavity 4. The first installation hole 8 respectively passes through the first plug 5 and the second plug 9 and is embedded in the interior of the fixed sheet 3. After the first plug 5 and the second plug 9 are inserted into the interior of the first installation cavity 4, the first installation hole 8 in the interior of the first plug 5 and the second plug 9 overlaps with the first installation hole 8 in the interior of the first installation cavity 4 at the installation position, as shown in the accompanying drawings, Figure 3 A first bolt 7 is arranged on one side of the exterior of the first installation hole 8. The exterior of the first bolt 7 is threadedly connected with the interior of the first installation hole 8.

[0027] The cast steel outer frame 1 has second mounting holes 18 at each of its four corners, and the fixing plates 3 have second bolts 17 at each of their four corners. The outer surface of the second bolts 17 engages with the inner thread of the second mounting holes 18. After fixing the floor 2 and the first bracket 11, the fixing plates 3 are fixed to both sides of the cast steel outer frame 1 by the second bolts 17. Fixing the fixing plates 3 also facilitates the fixing of the first insert 5 and the second insert 9.

[0028] To prevent the fixing piece 3 from easily loosening after being solely secured by the second bolt 17, such as... Figure 4 As shown, reinforcing plates 14 are provided at both ends and the bottom of the cast steel outer frame 1 and the fixing plate 3. The reinforcing plates 14 are welded and fixed to the fixing plate 3. The two sides of the cast steel outer frame 1 are provided with fourth mounting cavities 15 corresponding to the reinforcing plates 14. After the fixing plate 3 is attached to the cast steel outer frame 1 and fixed by the second bolt 17, the fixing plate 3 will drive the reinforcing plate 14 to be inserted into the fourth mounting cavity 15. The interior of the fourth mounting cavity 15 is connected to the external slot of the reinforcing plate 14. Further reinforcement can be achieved through the slot connection, so that the upper structure will not loosen when used and erected.

[0029] In order to fix the first bracket 11, all three third mounting cavities 13 inside the first bracket 11 are penetrated by the second insert 9 and the first insert 5. As the first bracket 11 is horizontally adjusted, when the three second insert 9 and the three first insert 5 penetrate and fix it, the three second insert 9 and the three first insert 5 will all penetrate the first bracket 11 and fix and support the first bracket 11 and the floor 2 at the top, thereby improving the support capacity of the first bracket 11.

[0030] Among them, such as Figure 5 As shown, a lever 6 is provided in the middle of the position through which the first bolt 7 passes by the first insert 5 and the second insert 9. The lever 6 is welded and fixed to the corresponding first insert 5 and the second insert 9 respectively. The protruding lever 6 makes it easy to pry out the first insert 5 and the second insert 9, and to adjust the installation position of the first insert 5 and the second insert 9.

[0031] Working principle: when using the groove type cast steel structure and adjusting, the floor 2 is longitudinally slid outside the second support 16 by the first support 11, after adjusting the size, the third mounting cavity 13 inside the first support 11 is overlapped with the second mounting cavity 12 inside the second support 16, the fixed sheet 3 is adhered on both sides of the floor 2, the reinforcing sheet 14 of the fixed sheet 3 is synchronously inserted into the fourth mounting cavity 15 inside the floor 2, the first insertion block 5 and the second insertion block 9 are respectively inserted into the first mounting cavity 4 on both sides of the cast steel outer frame 1, so that the first insertion block 5 and the second insertion block 9 are in contact with each other after sequentially penetrating the first mounting cavity 4, the second mounting cavity 12 and the third mounting cavity 13, three first insertion blocks 5 and three second insertion blocks 9 completely fill the third mounting cavity 13 inside the first support 11, the fixing of the first support 11 and the cast steel outer frame 1 after height adjustment can be realized through the penetration of the second insertion block 9 and the first insertion block 5, the fixing of the first insertion block 5 and the second insertion block 9 is realized by the first bolt 7 penetrating the first insertion block 5 and being embedded into the first mounting hole 8, when the second insertion block 9 is adhered with the first insertion block 5, the second insertion block 9 will be inserted into the first insertion block 5 through the extension block 10 and further fixed, further reinforcing the groove type cast steel structure, finally, the second bolt 17 penetrates the four corner positions of the fixed sheet 3, so that the second bolt 17 is embedded into the second mounting hole 18 on both sides of the cast steel outer frame 1, and the fixed sheet 3 is fixed on both sides of the cast steel outer frame 1.
