Compared with spiral and welded steel silos, assembled steel silos are more convenient and quick to install, with a shorter construction period. However, for existing assembled steel silos, the bearing capacity of the silo wall is often weak and prone to deformation, which limits the further application of assembled steel silos. Summary of the invention

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] 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.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a warehouse wall structure, which includes a warehouse wall 1 and a stiffening mechanism 2. The warehouse wall 1 is cylindrical, and includes a plurality of warehouse wall panels 11 spliced ​​in sequence along the circumferential direction. The stiffening mechanism 2 includes a prestressed cable 21, which is sleeved outside the warehouse wall 1 along the circumferential direction of the warehouse wall 1 and connected to the warehouse wall 1 through the connection between two adjacent warehouse wall panels 11, so as to apply a tightening force to the warehouse wall 1.

[0033] In the warehouse wall structure, multiple warehouse wall panels 11 are spliced ​​in sequence to realize the assembly of the warehouse wall 1. At this time, the warehouse wall 1 can be subjected to dispersed force through multiple warehouse wall panels 11, and the structural force is reasonable and not limited by the capacity of the steel plate warehouse. Further, considering that when the warehouse wall 1 is deformed, it is easy to start from the connection between two adjacent warehouse wall panels 11, so by arranging a prestressed cable 21 outside the warehouse wall 1, the prestressed cable 21 can be used to apply a tightening force to the warehouse wall 1 through the connection between two adjacent warehouse wall panels 11, thereby effectively improving the bearing capacity of the warehouse wall 1 and well avoiding the occurrence of deformation of the warehouse wall 1.

[0034] Furthermore, if Figure 2 and Figure 3 As shown, the warehouse wall plate 11 includes a plate body 111 and clamping parts 112 connected to both sides of the plate body 111. Two adjacent clamping parts 112 are clamped to each other to form a stiffening rib structure, and the prestressed cable 21 is connected to the warehouse wall 1 through the stiffening rib structure.

[0035] Thus, the assembly between two adjacent warehouse wall panels 11 can be realized by the clamping between two adjacent clamping parts 112, and the installation is more convenient and quick. On this basis, since the two adjacent clamping parts 112 are clamped to form a stiffening rib structure, the structural strength of the connection between the two adjacent warehouse wall panels 11 can be improved, and the warehouse wall 1 can be better prevented from deformation.

[0036] In this embodiment, the warehouse wall plate 11 is set as a steel plate. Each warehouse wall plate 11 can be regarded as a connection unit, and the number of connection units can be determined according to the diameter and height of the steel plate warehouse as a whole. Furthermore, in principle of convenient transportation, each connection unit can be divided into several sections along the axial direction of the warehouse wall 1, and the sections can be designed with different thicknesses according to the force. When each connection unit is divided into several sections, the warehouse wall plate 11 will include multiple sub-plates, and the upper and lower sub-plates in each connection unit can be connected by welding.

[0037] In terms of the specific structure of the warehouse wall plate 11, the plate body 111 is in the shape of an elongated strip, the long axis of the plate body 111 extends along the axial direction of the warehouse wall 1, and the length extension direction of the clamping portion 112 is consistent with the long axis direction of the plate body 111. At this time, the warehouse wall plate 11 is also in the shape of an elongated strip as a whole, and different numbers of warehouse wall plates 11 can be spliced ​​to form warehouse walls 1 of different diameters. As for the stiffening rib structure formed by the clamping of two adjacent clamping portions 112, it extends along the axial direction of the warehouse wall 1, which can match the axial length of the warehouse wall 1, and more effectively improve the bearing capacity of the warehouse wall 1.

[0038] It is understandable that after the bearing capacity of the silo wall 1 is improved, a larger diameter of the silo wall 1 can be designed to obtain a steel silo with a higher capacity.

[0039] Preferably, if Figure 3 As shown, the clamping part 112 is set as a U-shaped structure, and the opening of one of the two clamping parts 112 on the same warehouse wall plate 11 is set toward the outside of the warehouse wall 1, and the opening of the other is set toward the inside of the warehouse wall 1. At this time, for two adjacent clamping parts 112, since the openings of the two parts are in opposite directions, clamping can be achieved, and a stiffening rib structure with higher strength can be formed.

[0040] More specifically, if Figure 3 As shown, the U-shaped clamping portion 112 includes a first side edge 1121, a middle edge 1122, and a second side edge 1123 connected in sequence. The first side edge 1121 is bent and connected to the end of the plate body 111, and extends into or out of the warehouse wall 1; the middle edge 1122 is bent and connected to the first side edge 1121, and extends in a direction away from the plate body 111; the second side edge 1123 is bent and connected to the middle edge 1122, and extends out of or into the warehouse wall 1. When two adjacent clamping portions 112 are connected, the second side edge 1123 of any one of the two clamping portions 112 will be inserted into the opening of the other, thereby achieving the clamping of the two clamping portions 112.

[0041] Next, the arrangement of the stiffening mechanism 2 is further introduced.

[0042] In this embodiment, reference Figure 4A plurality of prestressed cables 21 are provided, and the plurality of prestressed cables 21 are arranged at intervals along the axial direction of the warehouse wall 1 , so that a tightening force can be applied to multiple parts of the warehouse wall 1 , so that the force on the warehouse wall 1 is more uniform.

[0043] For example, the prestressed cable 21 can be a prestressed steel strand or a prestressed steel wire, which has a large load-bearing safety factor and is safe and reliable to use. In terms of size, taking the thickness of the warehouse wall plate 11 as 8mm-25mm as an example, the diameter of the prestressed cable 21 can be selected as 15.2mm.

[0044] Preferably, the prestress of the prestressed cable 21 is configured to be adjustable, so that by adjusting the size of the prestress, when the warehouse wall 1 undergoes a large degree of deformation, a larger tightening force can be applied to the warehouse wall 1 to avoid insufficient tightening force and more effectively prevent the warehouse wall 1 from deforming; or when the warehouse wall 1 undergoes a small degree of deformation, a smaller tightening force can be applied to the warehouse wall 1 to avoid excessive tightening force (excessive tightening force itself may cause deformation of the warehouse wall 1).

[0045] like Figure 2 As shown, the stiffening mechanism 2 further includes a support assembly 22, which is arranged outside the warehouse wall 1, one end of the support assembly 22 is connected to the connection between two adjacent warehouse wall panels 11, and the other end extends in a direction away from the warehouse wall 1 and is connected to the prestressed cable 21. According to this, the installation of the prestressed cable 21 can be achieved through the support assembly 22, and the prestressed cable 21 is limited to apply a tightening force to the warehouse wall 1 through the connection between two adjacent warehouse wall panels 11, so as to ensure the accuracy of the force application position.

[0046] In this embodiment, the support assembly 22 is configured to be retractable, so that the tension of the prestressed cable 21 can be adjusted, thereby achieving the adjustment of the prestress of the prestressed cable 21.

[0047] Preferably, reference Figure 2 The support assembly 22 includes a support member 221 and a connector 222. One end of the support member 221 is connected to the connection between two adjacent warehouse wall panels 11, and the other end extends in the radial direction of the warehouse wall 1 away from the warehouse wall 1 to play a supporting role; one end of the connector 222 is threadedly connected to the support member 221, and the other end protrudes from the support member 221 and is connected to the prestressed cable 21 to achieve the installation of the prestressed cable 21.

[0048] When the support assembly 22 is connected to the prestressed cable 21 , since the connecting piece 222 is threadedly connected to the support piece 221 , the entire support assembly 22 can be extended and retracted by rotating the connecting piece 222 , thereby adjusting the tension of the prestressed cable 21 and changing the prestress of the prestressed cable 21 .

[0049] Of course, in other embodiments, the support assembly 22 may also be designed as other structures to achieve telescopic function, which is not limited to this embodiment.

[0050] Preferably, along the circumference of the warehouse wall 1, a plurality of support assemblies 22 are provided, and the plurality of support assemblies 22 are provided one by one with the plurality of warehouse wall panels 11, and the prestressed cable 21 is simultaneously connected with the plurality of support assemblies 22. At this time, the prestressed assembly can simultaneously apply a tightening force to the plurality of warehouse wall panels 11 through the plurality of support assemblies 22, and the anti-deformation effect is better.

[0051] In addition, it is understandable that when multiple support assemblies 22 are provided, the local tension of the prestressed cable 21 can also be adjusted by the extension and retraction of some support assemblies 22, with higher adjustment accuracy, better adaptability to the deformation of the warehouse wall 1, and better anti-deformation effect.

[0052] Furthermore, multiple support assemblies 22 can form a support unit, and multiple support units can be arranged outside the warehouse wall 1 along the axial direction of the warehouse wall 1. The multiple support units correspond one-to-one to the multiple prestressed cables 21, thereby realizing the installation of the multiple prestressed cables 21.

[0053] In this embodiment, the support member 221 is a frame structure made of a steel member such as a round tube or a square tube, and a nut is fixed on the support member 221, and the nut has an internal threaded hole extending radially along the warehouse wall 1. An external thread section is provided at one end of the connecting member 222 connected to the support member 221, and the connecting member 222 is threadedly connected to the internal threaded hole through the external thread section; a collar is provided at the other end of the connecting member 222, and the prestressed cable 21 is installed through the collar.

[0054] like Figure 2 As shown, the stiffening mechanism 2 further includes a telescopic member 23. Along the circumferential direction of the prestressed cable 21, the telescopic member 23 separates and connects the prestressed cable 21. At this time, the tightness of the prestressed cable 21 can also be changed by the telescopic member 23, thereby realizing the adjustment of the prestress of the prestressed cable 21.

[0055] Preferably, the telescopic member 23 is configured as a turnbuckle bolt. Figure 2 In one embodiment, at a separation of the prestressed cable 21, one end of the turnbuckle bolt may be connected to the connector 222, and the other end may be connected to the prestressed cable 21.

[0056] refer to Figure 5 In another embodiment, the two ends of the turnbuckle bolt can be directly connected to the prestressed cable 21, and the number and position of the turnbuckle bolt can be set according to actual needs. Since the structure of the turnbuckle bolt is a prior art, it will not be described here.

[0057] This embodiment also provides a steel plate silo, which includes the silo wall structure as described above.

[0058] In summary, this embodiment provides a silo wall structure and a steel silo, which have at least the following advantages:

[0059] (1) The prestressed cable 21 can apply a tightening force to the warehouse wall 1 through the connection between two adjacent warehouse wall panels 11, thereby effectively improving the bearing capacity of the warehouse wall 1 and better preventing the warehouse wall 1 from deforming;

[0060] (2) By providing the clamping portion 112 on the warehouse wall plate 11, the two adjacent warehouse wall plates 11 can be assembled by clamping between two adjacent clamping portions 112, and a stiffening rib structure is formed to improve the structural strength of the connection of the warehouse wall 1 and better prevent the warehouse wall 1 from deformation;

[0061] (3) By adjusting the prestress of the prestressed cable 21, different tightening forces can be applied to the warehouse wall 1 according to the different degrees of deformation that may occur in the warehouse wall 1, thereby preventing the tightening force from being insufficient or excessive, and more effectively avoiding deformation of the warehouse wall 1.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
