[0048] like Figure 5-8 As shown: the installation method of the assembled partition wall structure, step 1: placing L-shaped concrete prefabricated walls 1 in groups on the foundation at the edge of the adjacent partitions, so that the bottom plates 1-2 of each group of L-shaped concrete prefabricated walls 1 are arranged in reverse order;

[0049] Step 2: inject the grouting material into the gap between the bottom plate 1-2 and the foundation through the grouting groove 1-8 of the L-shaped concrete prefabricated wall 1, and adjust the diversion and exhaust function of the guide groove 1-9 and the grouting exhaust hole 1-10 so that the grouting material fills the gap between the bottom plate 1-2 and the foundation;

[0050] Step 3: After the grouting material between the bottom plate 1-2 and the foundation has initially solidified, the grouting material is continuously injected through the grouting grooves 1-8 to fill the gaps in the grouting grooves 1-8 between adjacent vertical plates 1-1; after the grouting material in the grouting grooves 1-8 has solidified, the L-shaped prefabricated concrete walls 1 are combined into a whole through the combined action of the flexible metal connectors 1-7 and the grouting material;

[0051] Step 4: pouring concrete inside and outside the bottom plate 1-2 of the group of L-shaped prefabricated concrete walls 1 to form the granary floor;

[0052] Step 5: placing the grooved wall panel 2 on the top of the assembled L-shaped concrete precast wall 1, the protrusions 1-6 of the L-shaped concrete precast wall 1 are in meshing state with the full-length protruding grooves 2-4 of the grooved wall panel 2, and the L-shaped concrete precast wall 1 and the grooved wall panel 2 are fixed with caulking material;

[0057] A high-performance grain warehouse, an assembled grain partition wall obtained according to the above-mentioned installation method.

[0058] Here’s how it works:

[0059] Generally speaking, the lateral pressure exerted by the lower layer of the piled grain on the surrounding area is greater, while the lateral pressure exerted by the upper layer on the surrounding area is smaller. The L-shaped concrete precast wall uses the deadweight of the grain stored inside the granary to prevent the granary wall from overturning under the lateral pressure of the grain. There is basically no need to transfer the lateral pressure of the grain to the main structural columns of the granary. Therefore, the main structural columns at the position of the partition wall can be eliminated, significantly reducing the construction cost; and the reinforced axils 1-3, steel cages 1-5 and other structures of the L-shaped concrete precast wall can enhance the strength of the L-shaped concrete precast wall to ensure that it can bear the lateral pressure of the grain.

[0060] In addition, the grouting grooves 1-8 and the flexible metal connectors 1-7 of the L-shaped concrete precast wall are combined with the grouting process to improve the connection strength between the left and right adjacent L-shaped concrete precast walls and ensure the air tightness and water tightness of the joints of the L-shaped concrete precast walls.

[0061] The connection between the bottom plate and the foundation and the pouring of concrete on the inner and outer sides of the bottom plate 1-2 form the granary floor. This can improve the connection strength between the L-shaped concrete precast wall and the foundation, further ensuring that the L-shaped concrete precast wall can bear the lateral pressure of the grain.

[0062] After the adjacent prefabricated components are connected with metal node plates, the grooved wall panel 2 has the ability to withstand a certain lateral pressure from the grain. However, since it is located at a high position on the grain, the lateral pressure it withstands is limited. Therefore, there is no need to consider the horizontal load of the grooved wall panel 2 too much. The installation of the prefabricated partition wall is completed by stacking multiple layers of the grooved wall panel 2.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
