Description

Technical Field

[0001] This utility model relates to a collaborative load-bearing column-supported double-walled square cylindrical warehouse. Background Technology

[0002] A square-tube silo complex is a combined grain storage group formed by assembling multiple square-tube silos. Each silo is typically supported by individual support columns, which are in direct contact with the bottom of the silo walls. Because the cross-sectional area of ​​the silo walls is larger than that of the support columns, and the height of the silo walls is greater than that of the support columns, both exhibit high bending stiffness. This leads to stress concentration at the connection interface, manifesting as: 1. Moment amplification: Under seismic horizontal forces, the silo walls transfer inertial forces to the support columns, with the bending moment at the joint reaching 3-5 times the mid-span bending moment; 2. Sudden shear force change: Differences in deformation coordination between the silo walls and columns cause a sharp increase in shear force at the joint area, exceeding the shear strength of the concrete; 3. Torsional effect: Deviation between the silo body and the support column axes induces additional torque, exacerbating the alternating tensile and compressive stresses at the joint area. Furthermore, differences in material stacking height and density among different square-tube silos can cause dynamic lateral pressure differences within the silo, leading to eccentric structural stress and increasing the risk of local stress peaks and overall instability. These factors easily result in concrete cracking and steel reinforcement yielding at the joints, seriously threatening structural safety. Utility Model Content

[0003] The purpose of this invention is to provide a collaborative load-bearing column-supported double-walled square cylindrical silo complex. Through upper and lower frame beams and friction pendulum seismic isolation bearings, a stiffness transition system is formed between the supporting columns and the silo walls, reducing local stress concentration. The upper frame beam collaboratively supports each individual silo, while the lower frame beam collaboratively connects each supporting column to complement the upper frame beam's support. This significantly reduces the stress concentration effect caused by direct rigid contact between the silo walls and supporting columns, balances the eccentric forces and large local stress peaks caused by the different weights of each individual silo, and ensures higher structural safety and stronger seismic performance of the square cylindrical silo complex.

[0004] The technical solution of this utility model is as follows: A collaborative load-bearing column-supported double-walled square cylindrical silo includes:

[0005] The rectangular single-compartment structure has multiple compartments arranged in a matrix, and its sidewalls are a double-wall structure consisting of an inner wall, an outer wall, and a cavity between the two.

[0006] Support columns are evenly arranged below each cylindrical silo.

[0007] The upper frame beam is a reinforced concrete structure cast in one piece, including installation grids that correspond one-to-one with the single-compartment square tubes. The side walls of the single-compartment square tubes sit on the upper surface of the installation grids.

[0008] The lower frame beam is a reinforced concrete structure cast in one piece, including support grids that correspond one-to-one with the installation grids, and each support column is supported on the lower part of the support grid.

[0009] There are multiple friction pendulum seismic isolation bearings, which are evenly distributed between each installation grid and support grid, including an upper bearing connected to the installation grid and a lower bearing connected to the support grid.

[0010] A spiral steel spring is installed in a one-to-one correspondence with the friction pendulum vibration isolation support. The spiral steel spring is sleeved on the friction pendulum vibration isolation support and its two ends are respectively connected to the upper and lower seats of the corresponding friction pendulum vibration isolation support.

[0011] There are multiple connecting columns, evenly distributed along the side walls of each cylindrical compartment. The length of the connecting columns extends in the vertical direction, and the two sides of the connecting columns are connected to the inner and outer walls respectively so that the inner and outer walls can work together to bear the force.

[0012] Based on the above scheme, the following improvements are made: each square hopper is connected to four square unloading hoppers at the bottom. A hopper support frame is provided between the inner walls of the support grids of the lower frame beam. The hopper support frame includes a cross-shaped bearing rod and four hopper support grids connected to the bearing rod to support the unloading hoppers.

[0013] Based on the above scheme, the following improvements are made: a shock-absorbing support is provided between the upper surface of the funnel support grid and the unloading funnel, and the shock-absorbing support is damped by springs.

[0014] Based on the above scheme, the following improvements are made: decorative sealing plates are provided around the upper and lower frame beams to cover the gap between the upper and lower frame beams. The decorative sealing plates are detachably connected to the upper and lower frame beams through a snap-fit ​​structure.

[0015] Based on the above scheme, further improvements are made as follows: the buckle structure includes a T-shaped slider on the inner surface of the decorative panel and T-shaped grooves on the outer circumferential surfaces of the upper and lower frame beams respectively.

[0016] Based on the above scheme, the following improvements are made: the upper part of the support column is symmetrically provided with arc-shaped transition support ribs along the length direction of the corresponding side of the support grid.

[0017] The beneficial effects of this technical solution are as follows: When a collaborative load-bearing column-supported double-walled square cylinder silo is in use, the individual square cylinder silos of the silo can be connected into a whole structure through the upper frame beam, so that the whole structure bears the load. Since the weight of each individual square cylinder silo is concentrated on the upper frame beam and then transferred downward as a whole, the weight of each individual square cylinder silo is balanced, reducing the stress concentration problem caused by the weight difference of each individual square cylinder silo. On the other hand, the setting of the connecting hidden columns can connect the inner and outer walls of the double-wall structure into a whole and fix it to the upper frame beam. This means that the weight of each individual square cylinder silo is no longer supported by the inner wall alone, but by the joint support of the inner and outer walls, which significantly improves the load-bearing capacity and avoids stress concentration at the inner wall. The stress is then transferred to the upper frame beam together, thus realizing the overall joint load-bearing between each individual square cylinder silo and between each inner and outer wall, resulting in stronger integration and enhanced load-bearing capacity. Furthermore, the lower frame beams create a unified load-bearing system for the supporting columns, preventing stress concentration caused by uneven stress distribution and potential damage to some high-stress columns. The lower frame beams can collectively bear the pressure from the individual cubicle sections above, distributing it more evenly across the supporting columns and reducing uneven stress distribution. Additionally, the evenly distributed friction pendulum isolation bearings between the mounting and supporting grids of the upper and lower frame beams allow for a flexible connection between the two frame beams, significantly improving seismic performance. The helical steel springs further enhance seismic performance, and by reinforcing the rigidity of the friction pendulum isolation bearings with sufficient flexibility, their rigid load-bearing capacity is maximized.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0030] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0031] A specific embodiment of this utility model of a collaboratively load-bearing column-supported double-walled square cylindrical silo group is as follows: Figure 1 As shown, a collaborative load-bearing column-supported double-walled square cylinder group consists of 6 square cylinder single silos 1 arranged in a matrix of 2×3. Its sidewalls are a double-walled structure composed of an inner wall 101, an outer wall 102, and a cavity 103 between them; as shown... Figure 8 As shown, to integrate the inner and outer walls into a single structure, connecting hidden columns 104 are provided. Multiple connecting hidden columns 104 are evenly distributed along the side walls of each cubic single-compartment 1. The length of each connecting hidden column 104 extends vertically, and both sides of the connecting hidden column 104 are connected to the inner and outer walls respectively, enabling the inner and outer walls to share the load collaboratively. The inner and outer walls, as well as the connecting hidden columns 104, are all reinforced concrete structures.

[0032] like Figure 2 , 3 As shown in Figures 6 and 7, the support columns 11 are evenly arranged below each square cylindrical silo 1. The upper part of the support columns 11 is symmetrically provided with arc-shaped transition support ribs 111 along the length direction corresponding to the corresponding side of the support grid 141. The upper frame beam 13 is a monolithically cast reinforced concrete structure, including installation grids 131 corresponding one-to-one with the square cylindrical silo 1, with the sidewalls of the square cylindrical silo 1 resting on the upper surface of the installation grids 131; the lower frame beam 14 is a monolithically cast reinforced concrete structure, including support grids 141 corresponding one-to-one with the installation grids 131, with each support column 11 supporting the lower part of the support grid 141; both the upper and lower frame beams are monolithic structures cast in place with reinforced concrete.

[0033] like Figure 2 , 3 As shown in Figures 6 and 7, there are multiple friction pendulum isolation supports 15, evenly distributed between each mounting grid 131 and support grid 141. These include an upper support 151 connected to the mounting grid 131 and a lower support 152 connected to the support grid 141. The upper support 151 and lower support 152 are connected by a mating spherical surface 1511 to dissipate energy from the friction pendulum. To prevent stress concentration between the upper and lower supports, the upper support 151 and lower support 152 have a smooth transition, avoiding right-angle structures that could generate stress. A helical steel spring 153 is provided correspondingly to each friction pendulum isolation support 15. The helical steel spring 153 is sleeved on the friction pendulum isolation support 15, and its two ends are connected to the corresponding upper and lower supports of the friction pendulum isolation support 15, respectively.

[0034] like Figure 1-3As shown, each cylindrical single compartment 1 is connected to four square unloading funnels 12 at its lower part. A funnel support frame 16 is provided between the inner walls 101 of the support grid 141 of the lower frame beam 14. The funnel support frame 16 includes a cross-shaped bearing rod 161 and four funnel support grids 162141 connected to the bearing rod 161 to support the unloading funnels 12. A shock-absorbing support is provided between the upper surface of the funnel support grids 162141 and the unloading funnel 12, and the shock-absorbing support is damped by springs. Decorative sealing plates 17 are provided around the upper and lower frame beams to cover the gap between them. The decorative sealing plates 17 are detachably connected to the upper and lower frame beams via a snap-fit ​​structure. The snap-fit ​​structure includes a T-shaped slider 171 on the inner surface of the decorative sealing plate 17 and T-shaped grooves 172 on the outer circumference of the upper and lower frame beams.

[0035] In use, the collaborative load-bearing column-supported double-walled square tube silo of this application connects the individual square tube silos 1 of the silo group into a unified structure via the upper frame beam 13, allowing it to bear the load as a whole. Since the weight of each individual square tube silo 1 is concentrated on the upper frame beam 13 and then transferred downwards as a whole, the weight of each individual square tube silo 1 is balanced, reducing the stress concentration problem caused by the weight difference of each individual square tube silo 1. On the other hand, the setting of the connecting hidden column 104 can connect the inner and outer walls of the double-wall structure into a whole and fix it to the upper frame beam 13 as a whole. This means that the weight of each individual square tube silo 1 is no longer borne solely by the inner wall 101, but is instead jointly borne by the inner and outer walls, significantly improving the load-bearing capacity and avoiding stress concentration at the inner wall 101. Instead, stress is transferred to the upper frame beam 13, thus achieving the overall joint load-bearing between each individual square tube silo 1 and between each inner and outer wall, resulting in stronger integration and enhanced load-bearing capacity. Furthermore, the lower frame beam 14 forms an integrated load-bearing system with all the support columns 11, avoiding stress concentration caused by different loads on each support column 11, which could lead to damage to some support columns 11 with higher stress. With the lower frame beam 14, the lower frame beam 14 can bear the pressure from each of the upper cylindrical compartments 1 as a whole, and then distribute it more evenly to each support column 11, reducing the unevenness of the load on each support column 11. In addition, since the friction pendulum seismic isolation bearings 15 are evenly distributed between the installation grids 131 and support grids 141 of the upper and lower frame beams, the connection between the two frame beams can be changed from rigid to flexible, which significantly improves the seismic performance. The installation of the helical steel spring 153 further improves the seismic performance, and the helical steel spring 153 strengthens the rigidity of the friction pendulum seismic isolation bearing 15, so that it has sufficient flexibility while maximizing its rigid load-bearing capacity.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
