Description

Technical Field

[0001] This invention belongs to the technical field of prefabricated building exterior wall ribbed panels, specifically relating to a prefabricated concrete grain silo ribbed insulation wall panel and its production method. Background Technology

[0002] Grain warehouses are the most important grain storage facilities. Currently, the main types of warehouses used include flat warehouses, shallow round warehouses, and vertical silos. Among them, flat warehouses are widely used because they have the characteristics of high grain loading height, large span, moderate cost, and good moisture-proof performance.

[0003] Ribbed insulation wall panels for grain storage are a high-performance enclosure structure system that specifically applies ribbed panel technology to grain storage buildings. It combines multiple functions such as structural load-bearing, high-efficiency insulation, moisture-proof and heat insulation, and airtightness control, making it particularly suitable for the construction of modern grain storage facilities with high requirements for temperature and humidity control.

[0004] However, existing ribbed insulation wall panels do not consider the load gradient characteristics of grain lateral pressure during design. The uniform thickness of the wall panels results in material redundancy and insufficient local strength. Furthermore, excessively thick wall panels are heavy, hindering hoisting and installation, potentially affecting the construction quality of the grain silo. This, in turn, impacts the silo's airtightness and thermal insulation performance, ultimately affecting the quality and safety of stored grain. Therefore, improvements are needed. Summary of the Invention

[0005] In order to solve all or part of the above problems, the purpose of this invention is to provide a prefabricated concrete grain silo ribbed insulation wall panel and its production method, which can ensure the supporting strength of the wall panel while reducing its own weight, thereby reducing production costs and facilitating construction operations such as hoisting and installation of the wall panel, thus ensuring the construction quality of the grain silo.

[0006] In a first aspect, the present invention provides a prefabricated concrete grain silo ribbed insulation wall panel, comprising a wall panel body and an insulation board, characterized in that the wall panel body comprises a main wall panel, two horizontal rib beams and two vertical rib columns, the two horizontal rib beams and the two vertical rib columns being integrally formed and connected to the outer surface of the main wall panel, the two horizontal rib beams and the two vertical rib columns together forming a "well"-shaped reinforcing rib grid, and forming nine weight-reducing zones on the outer surface of the main wall panel.

[0010] Optionally, the weight-reducing groove located at the center of the main wall panel is circular or polygonal.

[0011] Optionally, the four weight-reducing grooves located on the four sides of the main wall panel are circular and / or polygonal.

[0012] Optionally, the four weight-reducing grooves located at the four corners of the main wall panel are respectively irregularly shaped, and the four weight-reducing grooves are respectively connected to the outside of the main wall panel.

[0013] Optionally, the inner walls of the four weight-reducing grooves located at the four corners of the main wall panel each include a first wall surface and two second wall surfaces. The first wall surface is curved or zigzag, and the two second wall surfaces are curved, zigzag, or straight, respectively, and the two second wall surfaces are symmetrically arranged.

[0014] Secondly, the present invention provides a method for producing a prefabricated concrete grain silo ribbed insulation wall panel, comprising the following steps:

[0021] S12, simulates the application of grain lateral pressure load, with the bottom of the wall panel linearly distributed according to γh and uniformly distributed according to 0.3γh, where γ = grain bulk density and h = wall height;

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0041] Example 1

[0042] like Figures 1-8 The above is Embodiment 1 of the present invention. This embodiment discloses a prefabricated concrete grain silo ribbed insulation wall panel, including a wall panel body 1 and an insulation board 2 disposed on the outer surface of the wall panel body 1. The wall panel body 1 includes a main wall panel 11, two horizontal rib beams 12 and two vertical rib columns 13. The two horizontal rib beams 12 and the two vertical rib columns 13 are integrally formed and connected to the outer surface of the main wall panel 11.

[0043] In one embodiment, such as Figure 1 , Figure 2 As shown, two horizontal rib beams 12 are arranged in parallel, and two vertical rib columns 13 are arranged in parallel. The two horizontal rib beams 12 and the two vertical rib columns 13 are perpendicular to each other. That is, the two horizontal rib beams 12 and the two vertical rib columns 13 together form a "well"-shaped reinforcing rib grid 14, and make the outer surface of the main wall panel 11 form nine weight-reducing zones 15.

[0044] In this embodiment, the prefabricated concrete grain silo ribbed insulation wall panel utilizes a reinforcing rib grid 14 formed by two horizontal rib beams 12 and two vertical rib columns 13 to ensure the structural strength of the wall panel and thus its support capacity. Compared to a design where the wall panel has a uniform overall thickness, this design creates nine weight-reduction zones 15 within the wall panel, reducing its self-weight. This not only lowers production costs but also facilitates the hoisting and installation of the wall panel, thereby ensuring the quality of the grain silo construction.

[0045] In this embodiment, the wall panel body 1 is constructed by pouring concrete into a steel reinforcement frame. Specifically, the steel reinforcement frame forms the outline of the main wall panel 11, horizontal rib beams 12, and vertical rib columns 13. After pouring concrete into the steel reinforcement frame, the main body of the wall panel is formed. This design ensures that the horizontal rib beams 12 and vertical rib columns 13 also have internal skeletal support, thereby guaranteeing the structural strength of the horizontal rib beams 12 and vertical rib columns 13.

[0046] In one embodiment, such as Figure 1 , Figure 2 As shown, the outer surface of the main wall panel 11 is provided with nine weight-reducing grooves 16, and the nine weight-reducing grooves 16 are provided one-to-one with the nine weight-reducing zones 15, which further reduces the self-weight of the wall panel and can also improve the material redundancy problem, thereby reducing production costs.

[0047] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the insulation board 2 includes a main body 21. Nine first filling blocks 22 are integrally formed on the side of the main body 21 facing the main wall panel 11. Each of the nine first filling blocks 22 corresponds to one of the nine weight-reducing zones 15, and each first filling block 22 fills the corresponding weight-reducing zone 15. Each first weight-reducing block is integrally formed with a second filling block 23. Each of the nine second filling blocks 23 corresponds to one of the nine weight-reducing grooves 16, and each of the nine second filling blocks 23 fills the corresponding weight-reducing groove 16.

[0048] In this embodiment, thermal insulation material is poured onto the outer surface of the wall panel body. The thermal insulation material automatically fills the weight reduction groove 16 and the weight reduction area 15. After the thermal insulation material is cured, it is fixed to the wall panel body to form the thermal insulation board 2. The specific production method is detailed in Embodiment 2.

[0049] In one embodiment, such as Figure 4 As shown, the weight-reducing groove 16 located at the center of the main wall panel 11 is circular or polygonal, the four weight-reducing grooves 16 located on the four sides of the main wall panel 11 are circular and / or polygonal, and the four weight-reducing grooves 16 located at the four corners of the main wall panel 11 are respectively irregularly shaped, and the four weight-reducing grooves 16 are respectively connected to the outside of the main wall panel 11.

[0050] In this embodiment, the weight-reducing groove 16 located at the center of the main wall panel 11 is circular, and the four weight-reducing grooves 16 located on the four sides of the main wall panel 11 are each octagonal. Furthermore, the size of the weight-reducing groove 16 located at the center of the main wall panel 11 is larger than the size of the weight-reducing grooves 16 located on the four sides of the main wall panel 11 (e.g., ...). Figure 4 (as shown);

[0051] Alternatively, the weight-reducing groove 16 located at the center of the main wall panel 11 may be hexagonal, octagonal, or similar in shape, while two of the weight-reducing grooves 16 located on the four sides of the main wall panel 11 may be circular, and the other two may be octagonal (e.g., ...). Figure 5 (as shown);

[0052] Alternatively, the weight-reducing groove 16 located at the center of the main wall panel 11 may be hexagonal, octagonal, etc., and the four weight-reducing grooves 16 located on the four sides of the main wall panel 11 may also be circular (e.g., Figure 6 (as shown);

[0053] Of course, in other embodiments, the shape of the weight reduction groove 16 can be arbitrarily combined and set, which will not be listed in detail here.

[0054] In one embodiment, such as Figure 4 As shown, the inner walls of the four weight-reducing grooves 16 located at the four corners of the main wall panel 11 include a first wall surface 161 and two second wall surfaces 162. The first wall surface 161 is curved or zigzag, and the two second wall surfaces 162 are curved, zigzag, or straight, respectively, and the two second wall surfaces 162 are symmetrically arranged.

[0055] In this embodiment, the first wall surface 161 is arc-shaped, and the first wall surface 161 is a three-quarter circular arc. The two second wall surfaces 162 are also arc-shaped, and the two second wall surfaces 162 are each a quarter circular arc. Furthermore, the two second wall surfaces 162 are tangent to the first wall surface 161 (e.g., ...). Figure 4 (as shown);

[0056] Alternatively, the first wall surface 161 can be a polygonal shape, and the two second walls 162 can be curved, with each second wall surface 162 being a quarter-circle arc. Furthermore, the two second walls 162 are tangent to the first wall surface 161 (e.g., ...). Figure 7 (as shown);

[0057] Alternatively, the first wall 161 may be a polygonal shape, and the two second walls 162 may be either polygonal or straight (e.g., Figure 8 (as shown);

[0058] Of course, in other embodiments, the shapes of the first wall 161 and the second wall 162 can be arbitrarily combined and set, which will not be listed in detail here.

[0059] Example 2

[0060] like Figure 9 , Figure 10 The image shows Embodiment 2 of the present invention, which discloses a method for producing a prefabricated concrete grain silo ribbed insulation wall panel, comprising the following steps:

[0061] S1, the wall panel body 1 is designed through finite element topology optimization;

[0062] S2, Customize the wall panel mold based on the design results of the wall panel body 1;

[0063] S3, open the wall panel mold, place the steel reinforcement cage into the predetermined position of the wall panel mold, close the wall panel mold, pour concrete into the wall panel mold, and after the concrete has cured, remove the wall panel mold to realize the production of the wall panel body 1.

[0064] S4. Place the wall panel body 1 into the predetermined position in the casting mold, and pour the insulation material into the casting mold. The insulation material first fills the weight reduction groove 16, and then fills the weight reduction area 15. When the insulation material is flush with the reinforcing ribs 14, continue to pour the insulation material until the insulation material covers the wall panel body 1 to the preset thickness and then stop pouring. After the insulation material has solidified, remove the casting mold to realize the production of the dense rib insulation wall panel.

[0065] S1 includes the following steps:

[0066] S11, Establish the three-dimensional design domain of the wall panel and divide it into finite element meshes;

[0067] S12, simulates the application of grain lateral pressure load, with the bottom of the wall panel linearly distributed according to γh and uniformly distributed according to 0.3γh, where γ = grain bulk density and h = wall height;

[0068] S13 aims to maximize stiffness under volume constraints. The topology optimization constraint target volume is set to 80% of the initial volume. The objective function is defined as minimizing the sum of strain energies to 1. The SIMP algorithm is used for iterative optimization, and the penalty factor p = 3 is set.

[0069] S14, geometric reconstruction of the density cloud map, extraction of isosurfaces to generate rib grid wireframe model, thereby realizing the design of wall panel body 1.

[0070] The production method of the prefabricated concrete grain silo ribbed insulation wall panel in this embodiment introduces the variable density method (SIMP) into the design of flat warehouse wall panels. Based on the stress characteristics of grain lateral pressure (static load + dynamic load), an asymmetric load model is constructed (the internal pressure distribution of the grain pile is trapezoidal, with the pressure at the bottom being the greatest). Through topology optimization, a ribbed insulation wall panel that is different from the conventional one is generated.

[0071] As can be seen from Examples 1 and 2 above, the prefabricated concrete grain silo ribbed insulation wall panel has the following advantages:

[0072] 1. By setting a certain number of ribs on the wall panel and optimizing the topology, the amount of concrete used is reduced. While ensuring the strength of the wall panel itself, the weight of the wall is reduced. At the same time, the bonding area between the structural wall panel and the cast-in-place insulation material is increased, making the insulation board and the wall panel more firmly bonded and avoiding problems such as insulation board falling off.

[0073] 2. The wall panel and the insulation layer can be effectively bonded together by structural measures without the need for anchors, thus truly realizing the integration of the insulation structure and meeting fire protection requirements.

[0074] 2. The wall panels have a simple structure, conform to the prefabricated construction concept, have high factory production efficiency, help reduce building energy consumption, and allow for quick on-site construction.
