Description

Technical Field

[0001] This disclosure relates to the field of building construction technology, and in particular to a support umbrella frame for the roof of a shallow circular silo. Background Technology

[0002] In the field of building construction technology, existing support umbrella frames are prone to deformation, breakage and collapse during the cement pouring process of shallow circular silo roofs, which seriously affects the pouring quality and construction progress of shallow circular silo roofs.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this disclosure is to provide a support umbrella frame for the roof of a shallow circular silo, which can improve the pouring quality and construction progress of the shallow circular silo roof.

[0005] This disclosure provides a support umbrella frame for the roof of a shallow circular silo, the shallow circular silo comprising a silo body and a silo roof located above the silo body. The support umbrella frame for the shallow circular silo roof is used in the construction of the silo roof and includes: Central support frame; An umbrella-shaped support frame includes multiple inclined support columns. Each inclined support column has a first support connection portion and a second support connection portion. The first support connection portion is connected to the central support plate frame, and the second support connection portion is inclined downward along the height direction of the shallow circular hopper and extends away from the central support plate frame. A support bracket has a first support surface. When the support bracket is fixedly installed on the inner wall of the bin, the first support surface extends away from the inner wall of the bin. A second support connection part is located on the first support surface and the lower edge of the second support connection part is fixedly connected to the first support surface. A support reinforcement is located on the side of the support column away from the first support surface. The support reinforcement has a first reinforcing connection and a second reinforcing connection. The first reinforcing connection is fixedly connected to the side of the support column opposite to the first support surface, and the second reinforcing connection can at least abut against the inner wall of the hopper.

[0006] In one exemplary embodiment of this disclosure, the side of the supporting inclined column facing away from the first supporting surface is a first plane; the side of the first reinforcing connecting portion facing the supporting inclined column is a second plane, and the second plane is fixedly connected to the first plane.

[0007] In one exemplary embodiment of this disclosure, the second plane is fixedly connected to at least a portion of the first plane located in the second support connection portion.

[0008] In one exemplary embodiment of this disclosure, the width of the second plane in the first direction is greater than or equal to the width of the first plane in the first direction; Wherein, the first direction is perpendicular to the second direction and the extension direction of the second support connection, and the second direction is the direction from the first plane to the second plane.

[0009] In one exemplary embodiment of this disclosure, the side of the second reinforcing connection portion facing the inner wall of the compartment is parallel to the inner wall of the compartment, and the side of the second reinforcing connection portion facing the inner wall of the compartment can fit against and at least abut against the inner wall of the compartment.

[0010] In one exemplary embodiment of this disclosure, the side of the second reinforcing connection portion facing the inner wall of the container is fixedly connected to the inner wall of the container.

[0011] In one exemplary embodiment of this disclosure, the support reinforcement further includes: A telescopic structure, comprising a main body and a telescopic part, wherein the telescopic part is capable of moving toward or away from the main body; In this configuration, one of the main body and the telescopic part is connected to the first reinforcing connecting part, and the other is connected to the second reinforcing connecting part, so that the second reinforcing connecting part can move in a direction close to or away from the first reinforcing connecting part.

[0012] In one exemplary embodiment of this disclosure, the telescopic structure further includes: A driving member is disposed on the main body, and the driving member is used to drive the telescopic part to move in a direction closer to or away from the main body; A controller is connected to the drive unit, and the controller is used to control the drive unit to drive the telescopic part.

[0013] In one exemplary embodiment of this disclosure, the support reinforcement further includes: A guide structure, comprising a guide rod and a guide fitting, wherein one of the guide rod and the guide fitting is connected to the first reinforcing connection portion, and the other is connected to the second reinforcing connection portion; The guide rod passes through the guide fitting along the movement direction of the second reinforcing connection and is slidably connected to the guide fitting.

[0014] In one exemplary embodiment of this disclosure, the supporting inclined column is an I-beam; And / or, the inner wall of the silo body has multiple pre-embedded holes, the depth of which is less than the wall thickness of the silo body; the supporting bracket includes a supporting structure and a connecting structure, the supporting structure and the connecting structure are connected, the first supporting surface is located on the supporting structure, and the connecting structure is fixedly connected to the pre-embedded holes through a connector.

[0015] The technical solution provided in this disclosure can achieve the following beneficial effects: The support umbrella frame for the roof of a shallow circular silo provided in this embodiment includes a central support plate, an umbrella-shaped support frame, support brackets, and support reinforcements. The first support connection of the inclined support column is connected to the central support plate, and the second support connection is located on the first support surface of the support bracket, with its lower edge fixedly connected to the first support surface. This allows the central support plate and support brackets to support the inclined support column, reducing the probability of displacement and deformation of the umbrella-shaped support frame.

[0016] Simultaneously, by setting up supporting reinforcements and positioning them on the side of the inclined support column away from the first supporting surface—that is, the supporting brackets support the inclined support column below, and the supporting reinforcements support the inclined support column above—support can be provided simultaneously above and below the inclined support column using the supporting brackets and supporting reinforcements. This further improves the structural strength of the support frame and reduces the probability of displacement and deformation of the umbrella-shaped support frame. This ensures that the shape of the support frame does not change during the concrete pouring process of the shallow circular silo roof, effectively improving the construction quality of the shallow circular silo roof and reducing the probability of repairing or replacing the support frame, thus ensuring the construction progress of the shallow circular silo roof.

[0017] Furthermore, because the supporting inclined column is inclined, and the second support connection of the supporting inclined column is only fixedly connected to the first support surface at its lower edge, the connection between the supporting inclined column and the first support surface is a line contact and fixed connection, resulting in low connection strength between the supporting inclined column and the first support surface. When the supporting inclined column shifts and deforms during the concrete pouring process of the shallow circular silo roof, the connection between the lower edge of the second support connection and the first support surface is extremely prone to breakage, causing the supporting bracket to be unable to continue to effectively support the umbrella-shaped support frame.

[0018] Therefore, by setting up support reinforcements, this disclosure can stop the displacement and deformation of the support columns during the cement pouring process of the shallow circular silo roof. This reduces the probability of breakage at the connection between the lower edge of the second support joint and the first support surface due to displacement and deformation of the support columns. It can further ensure that the shape of the support umbrella frame does not change during the cement pouring process of the shallow circular silo roof, thereby further improving the construction quality of the shallow circular silo roof and further ensuring the construction progress of the shallow circular silo roof.

[0019] Furthermore, during the concrete pouring process of the shallow circular silo roof, even if the lower edge of the second support connection breaks at the junction with the first support surface, the supporting reinforcement can still effectively support the inclined support column. This ensures that even if the lower edge of the second support connection breaks at the junction with the first support surface, the inclined support column can still be effectively supported, preventing displacement, deformation, and collapse of the umbrella-shaped support frame and the entire shallow circular silo roof support structure. This improves the overall fault tolerance and reliability of the shallow circular silo roof support structure, further enhancing the construction quality and ensuring the construction progress of the shallow circular silo roof.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0025] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0026] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0027] In existing technologies, flat warehouses are commonly used to store grain. However, flat warehouses have a limited storage capacity, and the grain is prone to dampness and mold during storage, which seriously affects the quality of the stored grain.

[0028] Therefore, such as Figure 1 As shown, a shallow circular silo 01 is provided, which may include a silo body 011 and a silo roof 012 located above the silo body 011. The silo body 011 may be a hollow cylinder with an opening at its top. The silo roof 012 may be located on top of the silo body 011 and may cover the opening at the top of the silo body 011. The shape of the silo roof 012 may be umbrella-shaped (i.e., the shape of the silo roof 012 may be a hollow cone). The maximum diameter of the silo roof 012 may be larger than the maximum diameter of the silo body 011, so that the silo roof 012 can completely cover the opening of the silo body 011. Between a shallow circular silo 01 and a flat silo with the same floor area, the volume of the shallow circular silo 01 is larger than that of the flat silo, thus allowing for the storage of more grain. Furthermore, grain stored in a shallow circular silo 01 is less prone to moisture and mold, thus ensuring the quality of grain storage.

[0029] like Figure 1 and Figure 2 As shown, during the construction of the shallow circular silo roof 012, a support frame is required for support to facilitate subsequent cement pouring. However, the existing support frame is prone to deformation, breakage, and collapse during the cement pouring process of the shallow circular silo roof 012, which seriously affects the construction quality and progress of the shallow circular silo roof 012.

[0030] To solve the above technical problems, such as Figures 2 to 5 As shown, this disclosure provides a new support frame 02 for the roof of a shallow circular silo, which can be applied to the construction of the roof 012 of a shallow circular silo 01. The support frame 02 for the roof of a shallow circular silo provided by this disclosure can improve the pouring quality and construction progress of the roof 012 of the shallow circular silo.

[0031] like Figure 3As shown, the supporting umbrella frame 02 for the roof of the shallow circular silo provided in this disclosure may include: an umbrella-shaped support frame 1, a central support plate frame 2, and supporting brackets 3. The umbrella-shaped support frame 1 may include multiple inclined supporting columns 11, each having a first supporting connection portion 111 and a second supporting connection portion 112. The first supporting connection portion 111 can be connected to the central support plate frame 2, and the second supporting connection portion 112 can be inclined downwards along the height direction Z of the shallow circular silo 01 and extend away from the central support plate frame 2. The multiple inclined supporting columns 11 can be spaced apart along the circumferential direction W of the central support plate frame 2, thereby making the shape of the umbrella-shaped support frame 1 resemble an "umbrella," facilitating the subsequent casting to form an "umbrella-shaped" silo roof 012.

[0032] Optionally, such as Figure 2 and Figure 3 As shown, multiple supporting inclined columns 11 can be evenly spaced along the circumferential direction W of the central supporting plate 2. This arrangement can make the supporting capacity and structural strength of the umbrella-shaped support frame 1 more uniform, thereby improving the quality of the final silo top 012.

[0033] The umbrella-shaped support frame 1 can include 22 to 52 supporting inclined columns 11, for example: 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, etc. This arrangement avoids the problem of excessive weight due to an excessive number of supporting inclined columns 11 in the umbrella-shaped support frame 1, thus reducing the probability of collapse due to excessive weight and ensuring the quality and progress of the pouring construction of the shallow circular silo roof 012. Furthermore, it can also save on the cost of manufacturing the supporting umbrella frame 02 for the shallow circular silo roof. At the same time, this arrangement also avoids the problem of low support strength in the umbrella-shaped support frame 1 due to an insufficient number of supporting inclined columns 11, thereby ensuring sufficient support strength of the supporting umbrella frame while having fewer supporting inclined columns 11.

[0034] In some embodiments, such as Figure 4 and Figure 5 As shown, the supporting umbrella frame 02 of the shallow circular silo roof may further include supporting brackets 3. The supporting brackets 3 may have a first supporting surface 3a and may be fixedly installed on the inner wall of the silo body 011. Furthermore, when the supporting brackets 3 are fixedly installed on the inner wall of the silo body 011, the first supporting surface 3a may extend away from the inner wall of the silo body 011, and the second supporting connecting part 112 may be located on the first supporting surface 3a, with its lower edge fixedly connected to the first supporting surface 3a. With this configuration, the central supporting plate 2 and the supporting brackets 3 can be used to support the supporting inclined column 11, thereby reducing the probability of displacement and deformation of the umbrella-shaped support frame 1.

[0035] Optionally, the inner wall of the silo body 011 can have multiple pre-embedded holes, which can be pre-set during the casting process of the silo body 011. The depth of the pre-embedded holes can be less than the wall thickness of the silo body 011, that is, the pre-embedded holes do not penetrate the side wall of the silo body 011. This setting can ensure the airtightness of the shallow round silo 01, thereby reducing the probability of the grain getting damp and moldy during the storage process, and effectively improving the quality of the grain stored in the shallow round silo 01.

[0036] like Figure 5 As shown, the supporting bracket 3 may include a supporting structure 31 and a connecting structure 32, which can be connected. The first supporting surface 3a can be located on the supporting structure 31. The connecting structure 32 is fixedly connected to the pre-embedded hole through a connector, thereby fixing the supporting bracket 3 to the inner wall of the silo body 011. Simultaneously, since the connecting structure 32 is fixed to the inner wall of the silo body 011 using a pre-embedded hole, drilling holes in the inner wall of the silo body 011 during connection of the connecting structure 32 can be avoided, thus preventing damage to the side wall of the silo body 011 during drilling and ensuring the sealing of the shallow circular silo 01.

[0037] The connecting structure 32 can be plate-shaped, which increases the connection area between the connecting structure 32 and the inner wall of the hopper 011, thereby improving the connection strength between the connecting structure 32 and the inner wall of the hopper 011, and further improving the support strength of the supporting bracket 3. However, it is not limited to this, and the connecting structure 32 can also be other shapes. This disclosure does not limit it, and it can be selected and set according to the actual situation, all of which are within the protection scope of this disclosure.

[0038] The support structure 31 may include a support plate 311 and a reinforcing plate 312. One end of the support plate 311 may be fixedly connected to the connecting structure 32, and the other end of the support plate 311 may extend in a direction away from the inner wall of the silo body 011. The first support surface 3a may be the top surface of the support plate 311. One end of the reinforcing plate 312 may be fixedly connected to the bottom surface of the support plate 311 away from the connecting structure 32, and the other end of the reinforcing plate 312 may extend downward in a direction close to the connecting structure 32 and be fixedly connected to the connecting structure 32, so that the shape of the support bracket 3 is similar to a triangle, thereby further improving the structural strength and support strength of the support bracket 3.

[0039] In some embodiments, such as Figure 4 and Figure 5As shown, the supporting umbrella frame 02 of the shallow circular silo roof may further include a supporting reinforcement 4. The supporting reinforcement 4 may be located on the side of the supporting inclined column 11 away from the first supporting surface 3a, that is, the supporting reinforcement 4 may be located on the top surface of the supporting inclined column 11. The supporting reinforcement 4 may have a first reinforcing connection 41 and a second reinforcing connection 42. The first reinforcing connection 41 may be fixedly connected to the side of the supporting inclined column 11 away from the first supporting surface 3a, and the second reinforcing connection 42 may at least abut against the inner wall of the silo body 011.

[0040] It should be noted that "the second reinforcing connection 42 can at least abut against the inner wall of the silo body 011" means that the second reinforcing connection 42 can abut against the inner wall of the silo body 011, or that the second reinforcing connection 42 can be connected to the inner wall of the silo body 011. When the second reinforcing connection 42 abuts against the inner wall of the silo body 011, it facilitates the disassembly and installation of the supporting umbrella frame inside the shallow circular silo roof 012 on the inner wall of the silo body 011, saving labor costs and improving construction progress. When the second reinforcing connection 42 is connected to the inner wall of the silo body 011, it can improve the supporting strength of the supporting reinforcement 4.

[0041] This disclosure provides a supporting reinforcement 4, positioned on the side of the supporting inclined column 11 away from the first supporting surface 3a. Specifically, the supporting bracket 3 supports the lower part of the supporting inclined column 11, and the supporting reinforcement 4 supports the upper part. This allows for simultaneous support above and below the supporting inclined column 11 using the supporting bracket 3 and the supporting reinforcement 4. This further enhances the structural strength of the supporting umbrella frame and reduces the probability of displacement and deformation of the umbrella-shaped support frame 1. This ensures that the shape of the supporting umbrella frame remains unchanged during the cement pouring process of the shallow circular silo roof 012, effectively improving the construction quality of the shallow circular silo roof 012 and reducing the probability of repairing or replacing the supporting umbrella frame, thus guaranteeing the construction progress of the shallow circular silo roof 012.

[0042] Furthermore, since the inclined support column 11 is inclined, and the second support connection 112 of the inclined support column 11 is only fixedly connected to the first support surface 3a at its lower edge, the inclined support column 11 and the first support surface 3a are in line contact and fixedly connected, resulting in low connection strength between the inclined support column 11 and the first support surface 3a. When the inclined support column 11 is displaced and deformed during the cement pouring process of the shallow circular silo top 012, the connection between the lower edge of the second support connection 112 and the first support surface 3a is extremely prone to breakage, causing the support bracket 3 to be unable to continue to effectively support the umbrella-shaped support frame 1.

[0043] Therefore, by setting the support reinforcement 4, this disclosure can stop the displacement and deformation of the support column 11 during the cement pouring of the shallow circular silo roof 012. This can reduce the probability of the lower edge of the second support connection 112 breaking at the connection with the first support surface 3a due to the displacement and deformation of the support column 11. It can further ensure that the shape of the support umbrella frame does not change during the cement pouring of the shallow circular silo roof 012, thereby further improving the construction quality of the shallow circular silo roof 012 and further ensuring the construction progress of the shallow circular silo roof 012.

[0044] Furthermore, during the cement pouring process of the shallow circular silo roof 012, even if the lower edge of the second support connection 112 breaks at the connection point with the first support surface 3a, the support reinforcement 4 can still effectively support the support column 11. This ensures that even if the lower edge of the second support connection 112 breaks at the connection point with the first support surface 3a, the support column 11 can still be effectively supported, preventing displacement, deformation, and collapse of the umbrella-shaped support frame 1 and the entire support umbrella frame 02 of the shallow circular silo roof. This improves the overall fault tolerance and reliability of the support umbrella frame 02 of the shallow circular silo roof, further enhancing the construction quality of the shallow circular silo roof 012 and ensuring its construction progress.

[0045] In some embodiments, such as Figure 4 and Figure 5 As shown, the side of the supporting inclined column 11 facing away from the first supporting surface 3a can be a first plane, and the side of the first reinforcing connection part 41 facing the supporting inclined column 11 can be a second plane, which can be fixedly connected to the first plane. This arrangement ensures that the supporting inclined column 11 and the first reinforcing connection part 41 are in surface contact and fixedly connected, effectively increasing the connection area between them and thus improving their connection strength. Therefore, when the supporting inclined column 11 is subjected to force during the concrete pouring process of the shallow circular silo roof 012, the connection between the supporting inclined column 11 and the first reinforcing connection part 41 is less likely to break, ensuring effective support provided by the supporting reinforcement 4 to the umbrella-shaped support frame 1.

[0046] Optionally, the width of the second plane in the first direction can be greater than or equal to the width of the first plane in the first direction. The first direction can be perpendicular to both the second direction X and the extension direction Y of the second support connection 112, and the second direction X can be the direction from the first plane to the second plane. This configuration further increases the connection area between the support column 11 and the first reinforcing connection 41, thereby further improving the connection strength between the support column 11 and the first reinforcing connection 41, and further enhancing the support capacity of the support reinforcement 4.

[0047] Optionally, such as Figure 4 and Figure 5 As shown, the second plane can be fixedly connected to at least a portion of the first plane located in the second support connection 112. This arrangement allows the support reinforcement 4 to be connected to the second support connection 112 of the support column 11. Since the second support connection 112 of the support column 11 is close to the inner wall of the compartment 011, the length of the support reinforcement 4 can be shortened, thereby saving manufacturing costs and reducing the weight of the support reinforcement 4. This, in turn, saves manufacturing costs and reduces the weight of the support umbrella frame 02 for the shallow circular compartment roof.

[0048] The supporting inclined column 11 can be an I-beam. This design can improve the compressive strength and structural strength of the supporting inclined column 11, and reduce the probability of deformation fracture. Simultaneously, when the supporting inclined column 11 is an I-beam, it ensures that the side of the supporting inclined column 11 facing away from the first support surface 3a is flat, and also ensures that the side of the supporting inclined column 11 close to the first support surface 3a is flat. However, it is not limited to this; the supporting inclined column 11 can also be other types of supporting members, such as steel pipes, square steel, etc., and can be selected and set according to the actual situation, all of which are within the protection scope of this disclosure.

[0049] The supporting reinforcement 4 can be a hollow square tube. This design ensures that the supporting reinforcement 4 has sufficient supporting strength while further reducing its weight, and also ensures that the side of the first reinforcing connection 41 of the supporting reinforcement 4 facing the supporting inclined column 11 is flat. However, it is not limited to this; the supporting reinforcement 4 can also be other types of reinforcement, such as solid square tubes, steel pipes, etc., which can be selected and set according to the actual situation, all of which are within the protection scope of this disclosure.

[0050] In some embodiments, the side of the second reinforcing connection 42 facing the inner wall of the storage chamber 011 can be parallel to the inner wall of the storage chamber 011, thereby allowing the side of the second reinforcing connection 42 facing the inner wall of the storage chamber 011 to fit against and at least abut against the inner wall of the storage chamber 011. This arrangement increases the area of ​​at least abutment between the second reinforcing connection 42 and the inner wall of the storage chamber 011, thereby reducing the probability of displacement between the support reinforcement 4 and the inner wall of the storage chamber 011 when the umbrella-shaped support frame 1 is subjected to pressure during cement pouring, and thus improving the supporting capacity of the support reinforcement 4. Simultaneously, by increasing the area of ​​at least abutment between the second reinforcing connection 42 and the inner wall of the storage chamber 011, the pressure exerted by the support reinforcement 4 on the inner wall of the storage chamber 011 can be reduced, thereby reducing the probability of the support reinforcement 4 damaging the inner wall of the storage chamber 011.

[0051] Furthermore, the side of the second reinforcing connection 42 facing the inner wall of the silo body 011 can be fixedly connected to the inner wall of the silo body 011. For example, the side of the second reinforcing connection 42 facing the inner wall of the silo body 011 can be fixedly connected to the inner wall of the silo body 011 through a connector. With this arrangement, the probability of displacement between the supporting reinforcement 4 and the inner wall of the silo body 011 when the umbrella-shaped support frame 1 is subjected to pressure during cement pouring can be further reduced, thereby further improving the supporting capacity of the supporting reinforcement 4.

[0052] In some embodiments, such as Figures 4 to 7 As shown, the supporting reinforcement 4 may further include a telescopic structure 43, which may include a main body 431 and a telescopic part 432. The telescopic part 432 is capable of moving towards or away from the main body 431. One of the main body 431 and the telescopic part 432 may be connected to the first reinforcing connection 41, and the other may be connected to the second reinforcing connection 42; that is, the main body 431 may be connected to the first reinforcing connection 41, and the telescopic part 432 may be connected to the second reinforcing connection 42; or, the telescopic part 432 may be connected to the first reinforcing connection 41, and the main body 431 may be connected to the second reinforcing connection 42. Thus, as... Figure 6 and Figure 7 As shown, the second reinforcing connection 42 can move in a direction close to or away from the first reinforcing connection 41, thereby changing the length of the supporting reinforcement 4.

[0053] With this setting, such as Figure 6 As shown, when the diameter of the compartment 011 is large, the telescopic part 432 can move in a direction away from the main body 431, thereby causing the second reinforcing connecting part 42 to move in a direction away from the first reinforcing connecting part 41, increasing the length of the supporting reinforcing member 4, so that the second reinforcing connecting part can at least abut against the inner wall of the compartment 011. Figure 7As shown, when the diameter of the silo body 011 is small, the telescopic part 432 can move in a direction close to the main body 431, thereby causing the second reinforcing connection part 42 to move in a direction close to the first reinforcing connection part 41, shortening the length of the supporting reinforcement 4, so that the second reinforcing connection part can at least abut against the inner wall of the silo body 011. Thus, by providing the telescopic structure 43 to change the length of the supporting reinforcement 4, the support frame of the shallow circular silo body 01 can be used for shallow circular silos 01 of different diameters, thereby improving the environmental adaptability of the support frame 02 on the top of the shallow circular silo. Therefore, it is no longer necessary to manufacture a support frame matching the diameter of each shallow circular silo 01; the support frame can be used to match shallow circular silos 01 of more diameters, reducing the construction cost of building shallow circular silos 01 of different diameters.

[0054] The types of telescopic structures 43 may include, but are not limited to, hydraulic rods, pneumatic rods, etc., and can be selected and set according to actual conditions, all of which are within the protection scope of this disclosure.

[0055] Optionally, the telescopic structure 43 may further include a drive member and a controller. The drive member may be disposed on the main body 431 and may be used to drive the telescopic part 432 to move in a direction closer to or further away from the main body 431. When the telescopic structure 43 is a hydraulic rod, the drive member may be a hydraulic pump; when the telescopic structure 43 is a pneumatic rod, the drive member may be a pneumatic pump.

[0056] The controller can be connected to the drive unit, for example, wirelessly or wiredly. The controller can be used to control the drive unit's operation of the telescopic part 432. This configuration allows operators to remotely control the drive unit's operation of the telescopic part 432 by operating the controller, thereby remotely adjusting the length of the support reinforcement 4. This improves the convenience of adjusting the length of the support reinforcement 4, saves labor costs, and enhances operator safety.

[0057] In some embodiments, such as Figure 6 and Figure 7As shown, the supporting reinforcement 4 may further include a guide structure 44, which may include a guide rod 441 and a guide mating member 442. One of the guide rod 441 and the guide mating member 442 may be connected to the first reinforcing connection portion 41, and the other may be connected to the second reinforcing connection portion 42. That is, the guide rod 441 may be connected to the first reinforcing connection portion 41, and the guide mating member 442 may be connected to the second reinforcing connection portion 42; or, the guide rod 441 may be connected to the second reinforcing connection portion 42, and the guide mating member 442 may be connected to the first reinforcing connection portion 41. The guide rod 441 may pass through the guide mating member 442 along the movement direction of the second reinforcing connection portion 42 and be slidably connected to the guide mating member 442. This configuration allows the sliding fit between the guide member and the guide mating member 442 to guide the movement of the second reinforcing connection 42 away from or towards the first reinforcing connection 41, ensuring the accuracy of the movement of the second reinforcing connection 42 during the movement process. It can prevent the problem of reduced support effect of the support reinforcement 4 due to the displacement of the second reinforcing connection 42 during the movement process, thereby ensuring the support capacity of the support reinforcement 4 after the length is changed.

[0058] In some embodiments, such as Figure 3 and Figure 8 As shown, the central support frame 2 may include multiple support columns 24 and a first central plate 21, a second central plate 22, and a third central plate 23 arranged sequentially from top to bottom along the height direction Z of the shallow circular silo 01. Support columns 24 connect any two adjacent central plates to connect and support them. Specifically, multiple support columns 24 can connect the first central plate 21 and the second central plate 22, and these columns can be spaced apart along the circumferential direction W of the central support frame 2; similarly, multiple support columns 24 can also connect the second central plate 22 and the third central plate 23, and these columns can also be spaced apart along the circumferential direction W of the central support frame 2. The first support connection portion 111 of the aforementioned inclined support column 11 can connect to the edge of the first central plate 21, meaning the first support connection portion 111 of the inclined support column 11 can connect to the edge of the uppermost central plate.

[0059] like Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, the supporting umbrella frame 02 of the shallow circular silo roof may also include multiple first support rods 5 and multiple second support rods 6. One end of the first support rod 5 can be connected to the edge of the second central disk 22, and the other end of the first support rod 5 can be connected to the supporting inclined column 11 to support the supporting inclined column 11. One end of the second support rod 6 can be connected to the edge of the third central disk 23, and the other end of the second support rod 6 can be connected to the supporting inclined column 11 to support the supporting inclined column 11.

[0060] Understandably, multiple first support rods 5 can correspond one-to-one with multiple support inclined columns 11, one end of each first support rod 5 can be connected to the edge of the second central disk 22, and the other end of each first support rod 5 can be connected to its corresponding support inclined column 11; multiple second support rods 6 can correspond one-to-one with multiple support inclined columns 11, one end of each second support rod 6 can be connected to the edge of the third central disk 23, and the other end of each second support rod 6 can be connected to its corresponding support inclined column 11.

[0061] Therefore, the support umbrella frame 02 for the roof of the shallow circular silo provided in this disclosure can simultaneously support the support inclined column 11 through the first support rod 5 and the second support rod 6, which can increase the number of support points for supporting the support inclined column 11, thereby increasing the support strength of the support inclined column 11 and thus improving the structural strength of the support umbrella frame 02 for the roof of the shallow circular silo. This can reduce the probability of deformation, breakage and collapse of the support umbrella frame 02 for the roof of the shallow circular silo, and significantly improve the construction quality of the roof of the shallow circular silo 012.

[0062] Optionally, such as Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, the connection position between the second support rod 6 and the support inclined column 11 can be closer to the second support connection part 112 relative to the connection position between the first support rod 5 and the support inclined column 11. That is, the connection position between the second support rod 6 and the support inclined column 11 can be lower than the connection position between the first support rod 5 and the support inclined column 11. Since one end of the first support rod 5 is connected to the edge of the second central disk 22, and one end of the second support rod 6 is connected to the edge of the third central disk 23, the connection position between the second support rod 6 and the central support disk frame 2 can be lower than the connection position between the second support rod 6 and the central support disk frame 2. Therefore, when the connection position of the second support rod 6 and the support inclined column 11 is lower than the connection position of the first support rod 5 and the support inclined column 11, the problem of intersection between the second support rod 6 and the first support rod 5 can be avoided. This can prevent positional interference between the first support rod 5 and the second support rod 6, thereby ensuring the support effect of the first support rod 5 and the second support rod 6. This can further ensure the structural strength of the support umbrella frame 02 of the shallow circular silo roof, thereby further reducing the probability of deformation, breakage and collapse of the support umbrella frame 02 of the shallow circular silo roof, and further improving the construction quality of the shallow circular silo roof 012.

[0063] like Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the support umbrella frame 02 of the shallow circular silo roof can also include multiple reinforcing tension members 7. One end of the reinforcing tension member 7 can be connected to the edge of the third central disk 23, and the other end of the reinforcing tension member 7 can be connected to the support inclined column 11 to pull and support the support inclined column 11, so as to ensure the shape of the umbrella support frame 1 and further improve the structural strength of the support umbrella frame 02 of the shallow circular silo roof.

[0064] It is understandable that multiple reinforcing tension members 7 can correspond one-to-one with multiple supporting inclined columns 11, one end of each reinforcing tension member 7 can be connected to the edge of the third central disk 23, and the other end of each reinforcing tension member 7 can be connected to its corresponding supporting inclined column 11.

[0065] Optionally, such as Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the connection position between the reinforcing tension member 7 and the supporting inclined column 11 can be closer to the second support connection part 112 relative to the connection position between the second support rod 6 and the supporting inclined column 11. That is, the connection position between the reinforcing tension member 7 and the supporting inclined column 11 can be lower than the connection position between the second support rod 6 and the supporting inclined column 11. Thus, the reinforcing tension member 7 can be used to pull and support the supporting inclined column 11 at the position close to the second support connection part 112, thereby maximizing the pulling and supporting effect of the reinforcing tension member 7.

[0066] In some embodiments, such as Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the length of the second support rod 6 can be greater than the length of the first support rod 5, and the dimension of the second support rod 6 in the circumferential direction W of the central support plate 2 can also be greater than the dimension of the second support rod 6 in the circumferential direction W of the central support plate 2. With this configuration, because the second support rod 6 is longer, its larger dimension in the circumferential direction W of the central support plate ensures sufficient support strength to better support the inclined support column 11. Simultaneously, the pressure at the middle position of the inclined support column 11 is greater, thus increasing the compressive strength of the second support rod 6 by increasing its size improves its support effect at the middle position of the inclined support column 11. Furthermore, this configuration can reduce the weight of the first support rod 5, thereby further reducing the weight of the entire shallow circular silo roof support frame 02.

[0067] The dimension of the first support rod 5 in the circumferential direction W of the central support plate 2 can be larger than the dimension of the reinforcing tension member 7 in the circumferential direction W of the central support plate 2. Since the supporting force and tensile force required at the lower part of the supporting inclined column 11 are relatively small, this arrangement can reduce the weight of the reinforcing tension member 7 while ensuring that the reinforcing tension member 7 has sufficient tensile and supporting capacity, thereby reducing the weight of the entire support umbrella frame 02 of the shallow circular silo roof.

[0068] Optionally, the first support rod 5 can be a single channel steel. This configuration ensures that the first support rod 5 has sufficient bending resistance, thereby reducing the probability of deformation under pressure. For example, the first support rod 5 can be a #10 single channel steel, and the dimension of the single channel steel in the circumferential direction W of the central support plate 2 can be 100mm, but it is not limited to this.

[0069] And / or, the second support rod 6 can be a hollow circular steel tube. This configuration ensures that the second support has strong torsional resistance and rigidity, thus guaranteeing sufficient structural strength to provide good support for the inclined support column 11 even when the second support rod 6 has a long length. It also reduces the probability of deformation and torsion of the second support rod 6. At the same time, the hollow circular steel tube is lightweight, which reduces its weight while ensuring good support for the inclined support column 11, thereby reducing the weight of the entire support umbrella frame 02 of the shallow circular silo roof. For example, the second support rod 6 can be a hollow circular steel tube with a diameter of 108mm. The dimension of the hollow circular steel tube in the circumferential direction W of the central support plate 2 can be 108mm, but it is not limited to this.

[0070] And / or, the reinforcing member 7 can be a solid round steel rod. This configuration ensures that the reinforcing member 7 has strong tensile strength and strong supporting performance, thereby guaranteeing the traction and support effect of the reinforcing member 7 on the supporting inclined column 11. For example, the reinforcing member 7 can be a solid round steel tube with a diameter of 20mm. The dimension of the solid round steel tube in the circumferential direction W of the central support plate 2 can be 20mm, but it is not limited to this.

[0071] It should be noted that this disclosure does not impose specific restrictions on the types of the first support rod 5, the second support rod 6, and the reinforcing tension member 7. For example, the first support rod 5 can also be a hollow round steel rod, the second support rod 6 can also be a channel steel, and the reinforcing tension member 7 can also be a hollow round steel pipe. These can be selected and set according to actual needs, and all of these are within the protection scope of this disclosure.

[0072] In some embodiments, such as Figure 4 As shown, in the extending direction Y of the second support connection 112, there can be a first distance L1 between the connection position of the first support rod 5 and the support inclined column 11 and the first support connection 111, and there can be a second distance L2 between the connection position of the second support rod 6 and the support inclined column 11 and the connection position of the first support rod 5 and the support inclined column 11. The first distance L1 can be less than or equal to the second distance L2. This arrangement can improve the uniformity of force distribution on the first support rod 5 and the second support rod 6, and improve the supporting effect of the first support rod 5 and the second support rod 6 on the support inclined column 11.

[0073] In the extending direction Y of the second support connection 112, there can be a third distance L3 between the connection position of the reinforcing tension member 7 and the support inclined column 11 and the connection position of the second support rod 6 and the support inclined column 11. The second distance L2 can be less than or equal to the third distance L3. This arrangement can improve the uniformity of force distribution on the second support rod 6 and the reinforcing tension member 7, and can improve the support and tensioning effect of the first support rod 5 and the reinforcing tension member 7 on the support inclined column 11.

[0074] In some embodiments, such as Figure 9 and Figure 10 As shown, the support column 11 may be provided with a plurality of first connecting ears 113 and a plurality of second connecting ears 114. In the extension direction Y of the second support connecting part 112, the plurality of second connecting ears 114 may be close to the second support connecting part 112 relative to the plurality of first connecting ears 113, and the plurality of first connecting ears 113 and the plurality of second connecting ears 114 may be evenly spaced in the extension direction Y of the second support connecting part 112.

[0075] like Figure 9 and Figure 10As shown, the first support rod 5 has a first end 51 and a second end 52. The first end 51 of the first support rod 5 can be hinged to the edge of the second central disk 22, so that the first support rod 5 can rotate in the vertical plane. The second end 52 of the first support rod 5 can move in a direction close to or away from the first end 51, and the second end 52 of the first support rod 5 can be connected to any one of the first connecting ears 113. With this configuration, the connection position between the first support rod 5 and the supporting inclined rod can be adjusted according to the stress conditions during the construction of different shallow circular silo roofs 012, so as to ensure that the first support rod 5 can be supported in a better support position, thereby improving the support effect of the first support rod 5. It can also improve the applicability and environmental adaptability of the support umbrella frame 02 of the shallow circular silo roof, and can be used to construct shallow circular silo roofs 012 of different specifications. Therefore, it is no longer necessary to construct support frames 02 for shallow circular warehouse roofs of different specifications to correspond to different specifications of shallow circular warehouse roofs 012, which can reduce the construction cost of constructing shallow circular warehouse roofs 012 of different specifications.

[0076] Optionally, the first support rod 5 can be a telescopic rod, so that the second end 52 of the first support rod 5 can move in a direction close to or away from the first end 51. However, it is not limited to this. The first support rod 5 can also be other types of rods, as long as they can enable the second end 52 of the first support rod 5 to move in a direction close to or away from the first end 51.

[0077] like Figure 9 and Figure 10 As shown, the second support rod 6 may have a third end 61 and a fourth end 62. The third end 61 of the second support rod 6 may be hinged to the edge of the third central disk 23, allowing the second support rod 6 to rotate in the vertical plane. The fourth end 62 of the second support rod 6 may move in a direction close to or away from the third end 61 of the second support rod 6, and the fourth end 62 may be connected to any of the second connecting ears 114. With this configuration, the connection position between the second support rod 6 and the supporting inclined rod can be adjusted according to the stress conditions during the construction of different shallow circular silo roofs 012, ensuring that the second support rod 6 can be supported in a better support position, thereby improving the support effect of the second support rod 6. This also improves the applicability and environmental adaptability of the support umbrella frame 02 for the shallow circular silo roof, allowing the construction of shallow circular silo roofs 012 of different specifications using the support umbrella frame 02. Therefore, it is no longer necessary to construct support frames 02 for shallow circular warehouse roofs of different specifications to correspond to different specifications of shallow circular warehouse roofs 012, which can reduce the construction cost of constructing shallow circular warehouse roofs 012 of different specifications.

[0078] Optionally, the second support rod 6 can be a telescopic rod, so that the fourth end 62 of the second support rod 6 can move in a direction closer to or away from the third end 61. However, it is not limited to this. The second support rod 6 can also be other types of rods, as long as they can enable the fourth end 62 of the second support rod 6 to move in a direction closer to or away from the third end 61.

[0079] like Figure 9 and Figure 10 As shown, a plurality of third connecting ears 115 may also be provided on the support inclined column 11. In the extension direction Y of the second support connecting part 112, the plurality of third connecting ears 115 may be close to the second support connecting part 112 relative to the plurality of second connecting ears 114, and the plurality of third connecting ears 115 may be spaced apart in the extension direction Y of the second support connecting part 112.

[0080] The reinforcing member 7 may have a fifth end 71 and a sixth end 72. The fifth end 71 of the reinforcing member 7 may be hinged to the edge of the third central disc 23, allowing the reinforcing member 7 to rotate in the vertical plane. The sixth end 72 of the reinforcing member 7 may move in a direction close to or away from the fifth end 71 of the reinforcing member 7, and the sixth end 72 of the reinforcing member 7 may be connected to any one of the third connecting ears 115. With this configuration, the connection position between the reinforcing member 7 and the supporting diagonal rod can be adjusted according to the stress conditions during the construction of different shallow circular silo roofs 012, ensuring that the reinforcing member 7 can be supported and pulled in a more optimal position, thereby improving the pulling and supporting effect of the reinforcing member 7. This also improves the applicability and environmental adaptability of the support frame 02 for the shallow circular silo roof, allowing the support frame 02 for the shallow circular silo roof to be used to construct shallow circular silo roofs 012 of different specifications. Therefore, it is no longer necessary to construct support frames 02 for shallow circular warehouse roofs of different specifications to correspond to different specifications of shallow circular warehouse roofs 012, which can reduce the construction cost of constructing shallow circular warehouse roofs 012 of different specifications.

[0081] Optionally, the reinforcing member 7 can be a telescopic rod, so that the sixth end 72 of the reinforcing member 7 can move in a direction close to or away from the fifth end 71. However, it is not limited to this and the reinforcing member 7 can also be other types of rods, as long as they can enable the sixth end 72 of the reinforcing member 7 to move in a direction close to or away from the fifth end 71.

This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
