[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0037] According to an embodiment of the utility model, a silo template structure is provided, comprising:

[0038] The first template 11 and the second template 12 are arranged in an annular manner, and an annular space is formed between the first template 11 and the second template 12, and the annular space is suitable for pouring concrete to form the silo side wall 7;

[0039] The two support frames 2 are respectively located at the sides of the first formwork 11 and the second formwork 12 which are away from each other, and abut against the first formwork 11 and the second formwork 12 at the same time after the concrete pouring is completed;

[0040] The limiting structure 4 penetrates through the first template 11, the second template 12 and the silo side wall 7, and the two ends of the limiting structure 4 respectively limit the side surfaces of the two support frames 2 that are away from each other.

[0041] In the silo formwork structure provided in the present embodiment, the limiting structure 4 forms a limit on the sides of the first formwork 11 and the second formwork 12 that are away from each other through two support frames 2, so that after pouring concrete in the gap between the first formwork 11 and the second formwork 12, the distance between the first formwork 11 and the second formwork 12 is ensured to remain unchanged, so that the concrete solidifies to form the silo side wall 7. Compared with the slipform construction technology, the silo formwork structure has a lower degree of specialization and cost, and is suitable for silo structures with a lower height.

[0042] Specifically, the silo structure includes a plurality of columns 8 extending in the direction of gravity, the plurality of columns 8 are distributed in the circumferential direction of the silo, and the plurality of columns 8 are constructed before the first template 11 and the second template 12 are erected. Preferably, the spacing between two adjacent columns 8 is the same. The first template 11 and the second template 12 both extend in the direction of gravity and are arranged at intervals in the horizontal direction, so as to form an annular gap between the first template 11 and the second template 12. The columns 8 are located in the annular gap, the first template 11 abuts against the side of the column 8 facing the inside of the silo, and the second template 12 abuts against the side of the column 8 facing the outside of the silo. The columns 8 divide the annular gap into multiple sections, so as to be suitable for dividing the concrete in the annular gap, and by not pouring concrete between two adjacent columns 8, an opening is formed on the silo side wall 7. The curvature of the first template 11 matches the curvature of the inner wall of the silo side wall 7, and the curvature of the second template 12 matches the curvature of the outer wall of the silo side wall 7. Preferably, the first template 11 and the second template 12 are both plywood templates, and the thickness of the plywood template is 18 mm.

[0043] The two support frames 2 respectively limit the sides of the first template 11 and the second template 12 that are away from each other, thereby preventing the first template 11 and the second template 12 from moving in a direction away from each other, and limit the sides of the first template 11 and the second template 12 that are close to each other through the columns 8 in the annular space, thereby preventing the first template 11 and the second template 12 from moving in a direction close to each other, and then fix the relative positions of the first template 11 and the second template 12 through the support frames 2 and the columns 8, so that the concrete solidifies in the annular space to form the silo side wall 7. Preferably, along the gravity direction, the elevation of the first template 11 and the second template 12 is the same as the elevation of the columns 8. The two support frames 2 are fixedly connected to the first template 11 and the second template 12 by screws.

[0044] The limiting structure 4 passes through the first template 11, the second template 12, and the annular gap between the first template 11 and the second template 12, and the two ends of the limiting structure 4 are respectively in contact with the sides of the two support frames 2 that are away from each other to form a limit, so as to prevent the two support frames 2 from moving in the direction away from each other, thereby limiting the first template 11 and the second template 12. The limiting structure 4 and the support frame 2 limit the sides of the first template 11 and the second template 12 that are away from each other, and the columns 8 limit the sides of the first template 11 and the second template 12 that are close to each other, so that the first template 11 and the second template 12 can be used as the template for the concrete in the annular gap to form the silo side wall 7. Compared with the slipform construction technology, the silo template structure is simple to operate, low in cost, and can effectively ensure the construction quality and safety, shorten the construction period, and is suitable for silo structures with low heights. Therefore, when constructing a silo structure with low heights, the silo template structure of this embodiment is adopted to avoid the use of the slipform construction technology with a high degree of specialization and high cost.

[0045] In some embodiments, in combination Figures 1 to 4 As shown, the limiting structure 4 includes a water-stop screw 41 penetrating the first template 11 and the second template 12, and nuts 42 arranged at both ends of the water-stop screw 41, and the nuts 42 are suitable for limiting the side of the support frame 2 away from the silo side wall 7.

[0046] Specifically, the water-stop screw 41 can be a conventional one-stage water-stop screw or a three-stage water-stop screw. The nuts 42 at both ends of the water-stop screw 41 are suitable for abutting against the sides of the two support frames 2 that are away from each other, so as to limit the two support frames 2 through the pulling action of the water-stop screw 41. Preferably, the extension direction of the water-stop screw 41 is parallel to the radial direction of the silo side wall 7.

[0047] In some embodiments, in combination Figures 1 to 4 As shown, the number of the limiting structures 4 is greater than one.

[0048] The silo template structure provided in this embodiment is beneficial to improving the abutment stability of the limiting structures 4 against the support frames 2 by setting a plurality of limiting structures 4, thereby ensuring the abutment stability of the two support frames 2 against the first template 11 and the second template 12.

[0049] Preferably, multiple limiting structures 4 are arranged in an array along the circumferential direction of the silo side wall 7 and the gravity direction. The relative positions of the two support frames 2 and the first template 11 and the second template 12 are limited by the multiple limiting structures 4, which is beneficial to enhancing the connection stability between the two support frames 2 and the first template 11 and the second template 12.

[0050] In some embodiments, in combination Figures 1 to 4As shown, along the horizontal direction, the distance between two adjacent limiting structures 4 is S, where S≤600mm; along the gravity direction, the distance between two adjacent limiting structures 4 is H, where H≤250mm.

[0051] The silo template structure provided in this embodiment limits the distance between two adjacent limiting structures 4 so as to meet the construction requirements, which is beneficial to ensuring the safety of construction and the stability of the template structure.

[0052] In some embodiments, in combination Figures 1 to 4 As shown, a vertical rod 3 is arranged between the nut 42 and the support frame 2 , and one side of the vertical rod 3 abuts against the support frame 2 , and the other side abuts against the nut 42 .

[0053] In the silo template structure provided in this embodiment, multiple nuts 42 are simultaneously in contact with the vertical poles 3, and the vertical poles 3 form a limit for the support frame 2, which is beneficial to improving the overall stability of the support frame 2 limited by the multiple limit structures 4.

[0054] Specifically, there are multiple vertical poles 3, each vertical pole 3 extends along the gravity direction. Preferably, along the gravity direction, the height of the vertical pole 3 is adapted to the height of the first template 11 and the second template 12. Figure 2 and Figure 4 As shown, along the extension direction of the vertical pole 3, several water-stopping screws 41 are located on the same vertical plane, and a vertical pole 3 is provided on both sides of each end of the water-stopping screw 41 along its extension direction, and the side of the vertical pole 3 close to the silo side wall 7 abuts against the support frame 2, and the side of the vertical pole 3 away from the silo side wall 7 abuts against multiple nuts 42 located on the same vertical plane, so that multiple nuts 42 abut against the support frame 2 via the vertical pole 3, thereby improving the overall stability of the limiting structure 4 limiting the support frame 2. Preferably, two adjacent vertical poles 3 can also be tied together to further improve the overall stability.

[0055] In some embodiments, in combination Figures 1 to 4 As shown, a cushion block 6 is further provided between the upright pole 3 and the nut 42 , and one side of the cushion block 6 abuts against the upright pole 3 , and the other side abuts against the nut 42 .

[0056] In the silo template structure provided in this embodiment, the nut 42 is abutted against the vertical pole 3 through the spacer block 6, which is beneficial to improving the abutment stability between the nut 42 and the vertical pole 3.

[0057] The vertical pole 3 can be a steel pipe, or a box steel or an I-beam. As a feasible implementation form, the vertical pole 3 is a steel pipe, and the cushion block 6 is a mountain-shaped clamp. The diameter of the steel pipe is adapted to the size of the arc-shaped groove of the mountain-shaped clamp, so that the arc-shaped groove of the mountain-shaped clamp abuts against the outer peripheral wall of the steel pipe. The mountain-shaped clamp is located between the vertical pole 3 and the nut 42. The arc-shaped groove of the mountain-shaped clamp faces the silo side wall 7 and abuts against the vertical pole 3. The flat surface of the mountain-shaped clamp abuts against the nut 42, so that one nut 42 abuts against two vertical poles 3 at the same time through the mountain-shaped clamp, thereby improving the abutment stability and reliability of the nut 42 against the vertical pole 3.

[0058] As an additional implementation form, the vertical pole 3 is box-shaped steel or I-shaped steel, the spacer 6 is a straight plate, the spacer 6 is located between the vertical pole 3 and the nut 42, the main plane on one side of the straight plate abuts against the nut 42, and the main plane on the other side abuts against the vertical pole 3. Each nut 42 is suitable for abutting against two vertical poles 3 at the same time through the spacer 6, thereby increasing the effective area of ​​the nut 42 on the vertical pole 3, and then improving the abutment stability and reliability of the nut 42 on the vertical pole 3.

[0059] In some embodiments, in combination Figures 1 to 4 As shown, the support frame 2 includes a plurality of first support rods 21 extending along the gravity direction, and a plurality of second support rods 22 extending along the horizontal direction, and the first support rods 21 and the second support rods 22 are fixedly connected.

[0060] Specifically, a plurality of first support rods 21 are spaced apart along the circumferential direction of the silo side wall 7, and a plurality of second support rods 22 are spaced apart along the gravity direction. Preferably, the spacing between two adjacent first support rods 21 is the same, and the spacing between two adjacent second support rods 22 is the same.

[0061] In some embodiments, in combination Figures 1 to 4 As shown, the curvature of the second support rod 22 matches the curvature of the inner wall or outer wall of the silo side wall 7 .

[0062] The silo template structure provided in this embodiment ensures the abutment stability between the second support rod 22 and the first template 11 and the second template 12 by making the curvature of the second support rod 22 match the curvature of the inner wall or the outer wall of the silo side wall 7 .

[0063] Specifically, the curvature of the second support rod 22 located on the inner side of the silo side wall 7 is adapted to the curvature of the inner wall of the silo side wall 7, so as to facilitate the support frame 2 on the inner side of the silo side wall 7 to fit with the first template 11, so as to improve the abutment stability between the support frame 2 and the first template 11; the curvature of the second support rod 22 located on the outer side of the silo side wall 7 is adapted to the curvature of the outer wall of the silo side wall 7, so as to facilitate the support frame 2 on the outer side of the silo side wall 7 to fit with the second template 12, so as to improve the abutment stability between the support frame 2 and the second template 12.

[0064] In some embodiments, in combination Figures 1 to 4 As shown, along the horizontal direction, the distance between two adjacent first support rods 21 is s, where s≤600mm; along the gravity direction, the distance between two adjacent second support rods 22 is h, where h≤250mm.

[0065] The silo template structure provided in this embodiment limits the distance between two adjacent first support rods 21 and two adjacent second support rods 22 so as to ensure the effect of the support frame 2 on abutting and limiting the first template 11 and the second template 12.

[0066] In some embodiments, in combination Figures 1 to 4 As shown, a lifting ring 5 is fixedly connected to the upper end of the support frame 2 along the gravity direction.

[0067] The silo template structure provided in this embodiment has a lifting ring 5 fixedly connected to the support frame 2, so that the support frame 2 can be hoisted through the lifting ring 5 during construction, thereby improving construction efficiency.

[0068] Specifically, a plurality of lifting rings 5 ​​are fixedly connected to the first support rod 21 or the second support rod 22 at the top of the support frame 2. Preferably, the plurality of lifting rings 5 ​​are evenly distributed along the circumferential direction of the silo side wall 7. During construction, the lifting rings 5 ​​are used as lifting points to facilitate lifting the support frame 2 into place, facilitate construction, improve construction efficiency, and shorten construction period.
