[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0023] In this embodiment, as Figure 1 - Figure 7 As shown, a simple equipment foundation steel formwork device includes folded steel plates 10. The surface of the folded steel plates 10 may have scale lines. Several folded steel plates 10 are spliced ​​together by fixing bolts 20 to form a steel plate structure for pouring equipment foundation 30. A support mechanism 40 is provided on the side of the folded steel plate 10 away from the equipment foundation 30 to increase the stability when adjacent folded steel plates 10 are spliced. This device uses the folded steel plate 10 as the basic unit, and aligns it with the connecting plates 12 of adjacent folded steel plates through the connecting plates 12 at both ends, using fixing bolts 20. The connecting plate 12 is used to achieve a tight splicing. After several folded steel plates 10 are spliced ​​together, they form a closed or semi-closed steel plate structure. The internal space of this structure is the pouring cavity of the equipment foundation 30. Concrete is poured into the spliced ​​steel plate structure to ensure that the concrete surface is smooth and to avoid honeycomb and pitting problems caused by traditional wooden formwork splicing. After the concrete is cured and formed, the support crossbar 15 and support mechanism 40 are removed in sequence, and then the fixing bolts 20 are unscrewed to disassemble the folded steel plates 10. The folded steel plates 10 made of steel can be reused to extend their service life. The folded steel plate 10 includes an L-shaped plate 11. The steel material has strong corrosion resistance, which can increase the number of times it can be reused and reduce material waste. Both ends of the L-shaped plate 11 are fixedly provided with connecting plates 12. The connecting plates 12 extend towards the side away from the equipment foundation 30. The bottom of the L-shaped plate 11 is provided with a supporting base plate 13. The L-shaped plate 11, the connecting plates 12 and the supporting base plate 13 are integrated structures. The number of folded steel plates 10 spliced ​​can be adjusted according to the size requirements of the equipment foundation 30. The size of the folded steel plate 10 can be adjusted according to the actual use requirements. Among them, such as Figure 3 , Figure 5 and Figure 7 As shown, the support mechanism 40 includes several first mounting seats 41 detachably connected to the L-shaped plate 11. Several screw holes, matching the positions of the first mounting seats 41, are provided at the middle position of the surface of the L-shaped plate 11 for easy replacement and maintenance. A movable rod 42 is rotatably connected to each of the first mounting seats 41. The movable rod 42 has positioning holes on its surface. The end of the movable rod 42 is slidably disposed in a movable sleeve 43. A movable groove is provided inside the movable sleeve 43. The movable rod 42 is connected to the inner wall of the movable groove by a spring, serving as a limiting and connecting element. The end of the movable sleeve 43 is connected to the first mounting seat 41. The two mounting bases 44 are rotatably connected. The bottom of the second mounting base 44 is provided with several insert rods 45. After the splicing is completed, the support mechanism 40 is installed on the side of the folded steel plate 10 away from the pouring cavity. The first mounting base 41 is fixed through the screw holes on the surface of the L-shaped plate 11. The extension length of the moving rod 42 in the moving sleeve 43 is adjusted. Then the insert rods 45 at the bottom of the second mounting base 44 are inserted into the ground to form a triangular support system, which counteracts the lateral thrust generated during concrete pouring, prevents the folded steel plate 10 from deforming or displacing, improves the resistance to lateral deformation, and reduces the amount of subsequent repair work. Among them, such as Figure 3 - Figure 6As shown, the L-shaped plate 11 has a combination mechanism 50 at its corner for changing the corner shape. The combination mechanism 50 includes a combination block 51 that matches the corner. If the equipment foundation 30 has a non-right-angle corner requirement such as an arc, V-shape, or trapezoid, it can be adjusted through the combination mechanism 50. The locking blocks 52 on both sides of the combination block 51 are slidably inserted into the locking grooves 54 at the corner of the L-shaped plate 11, so that the combination block 51 fits the corner position. The locking blocks 52 are symmetrically arranged on both sides of the combination block 51. Several locking blocks 52 corresponding to the locking blocks 52 are fixedly arranged on the side of the L-shaped plate 11 away from the equipment foundation 30. The reinforcing plate 53 has a slot 54 extending in its direction. The locking block 52 is slidably disposed inside the slot 54. The locking block 52 and the reinforcing plate 53 can also be fixed by several pins (not shown in the figure) to increase stability. The combined block 51 has an opening 55 on the side facing the equipment foundation 30 for adjusting different angle styles. The opening 55 is set as one of arc, V and trapezoid. The opening 55 can be directly used as the angle boundary of the casting cavity without replacing the overall template. The style also includes other non-standard foundation shapes to adapt to a variety of angle styles. Among them, such as Figure 1 and Figure 3 As shown, the height of the assembly block 51 is greater than the height of the L-shaped plate 11, which can realize the transition of different heights at the bend. The materials of the assembly block 51 and the L-shaped plate 11 are the same, which helps to extend the service life. Among them, such as Figure 1 and Figure 3 As shown, several support columns 14 are evenly distributed on the top of the L-shaped plate 11. The support columns 14 can be connected to each other by support crossbars 15. The support columns 14 and support crossbars 15 can be fixed by bolts, and then assembled into a top support frame to further enhance the overall longitudinal stability of the device and prevent the top of the folded steel plate 10 from expanding outward during the pouring process. Among them, such as Figure 3 and Figure 5 As shown, multiple reinforcing ribs 16 are provided on the side walls opposite to the L-shaped plate 11 and the supporting base plate 13 in the horizontal direction. The reinforcing ribs between the L-shaped plate 11 and the supporting base plate 13 enhance the structural strength of the folded steel plate 10 itself and prevent cracking caused by excessive local stress. Example 2

[0024] The difference from Example 1 is that, as in Example 1, Figure 7 As shown, the surface of the movable sleeve 43 is provided with multiple round holes at equal intervals. The round holes on the surface of the movable sleeve 43 can be aligned with the positioning holes on the movable rod 42. The relative position of the movable rod 42 and the movable sleeve 43 can be fixed by inserting the positioning pin, so as to achieve the locking effect of the support length, avoid the change of support length due to spring fatigue during the pouring process, and make the support point bear the force evenly.

[0025] In use, according to the size and shape requirements of the equipment foundation 30, several folded steel plates 10 are selected. Adjacent folded steel plates 10 are aligned through the bolt holes on the connecting plate 12, and splicing is completed using fixing bolts 20 to form a steel plate structure. The integrated design of the L-shaped plate 11 and the supporting base plate 13 can directly serve as the side wall and bottom support for casting, increasing the contact area with the ground and reducing the probability of tilting during casting of the folded steel plate 10. A support mechanism 40 is installed on the side of the folded steel plate 10 away from the casting cavity. The first mounting seat 41 is fixed through the bolt holes on the surface of the L-shaped plate 11. The extension length of the moving rod 42 in the moving sleeve 43 is adjusted, and then the second mounting seat 44 is used to fix it. The bottom insert rod 45 is inserted into the ground or foundation pad to form an inclined support. If the equipment foundation 30 is high, the support crossbar 15 can be connected between the support columns 14 at the top of the L-shaped plate 11 to build a horizontally stable frame and prevent the folded steel plate 10 from displacing due to the lateral pressure of the concrete. If the equipment foundation 30 has a non-right angle, the locking block 52 of the combination mechanism 50 is slid along the locking groove 54 of the L-shaped plate 11 so that the combination block 51 fits against the angle. The angle pattern is adjusted by using the combination block 51 facing the opening 55 of the pouring cavity to ensure that the concrete meets the shape requirements for equipment installation after pouring. Then, concrete is poured into the assembled pouring cavity to complete the overall operation.

[0026] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
