[0006] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated steel bar stacking rack, comprising a supporting column, a first crossbeam, a second crossbeam, and bolt assemblies, wherein assembly assemblies are provided between the supporting column and the first and second crossbeams, and installation assemblies are provided between the upper and lower ends of the supporting column.

[0014] As a further description of the above technical solution:

[0015] The assembly component includes an assembly through hole and a through hole connecting plate. The assembly through hole is located at both ends of the surfaces of the first crossbeam and the second crossbeam. The outer wall of the through hole connecting plate is fixedly connected to the outer wall of the supporting column.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a prefabricated rebar stacking rack, comprising a supporting column 1, a first crossbeam 2, a second crossbeam 3, and a bolt assembly 7. Specifically, the first crossbeam 2 is a 1M standard crossbeam, the second crossbeam 3 is a 2M standard crossbeam, and the bolt assembly 7 uses M20×60 bolts. An assembly assembly 5 is provided between the supporting column 1 and both the first crossbeam 2 and the second crossbeam 3. The assembly assembly 5 includes an assembly through hole 51 and a through hole connecting plate 52. The assembly through holes 51 are located at both ends of the surfaces of the first crossbeam 2 and the second crossbeam 3. The outer wall of the through hole connecting plate 52 is fixedly connected to the outer wall of the supporting column 1. There are four through hole connecting plates 52 in total. The four through-hole connecting plates 52 are distributed around the outer surface of the support column 1, and the surfaces of the four through-hole connecting plates 52 are all provided with anti-slip textures 53. Through the assembly component 5 and the bolt assembly 7, the through-hole connecting plates 52 on the support column 1 are connected and installed with the assembly through holes 51 on the first crossbeam 2 and the second crossbeam 3. The pure bolt connection design completely avoids the welding process, reducing construction costs and safety risks. At the same time, the anti-slip textures 53 on the surface of the through-hole connecting plates 52 and the layout of the bolt assembly 7 form a double anti-slip mechanism, improving the reliability of the node by 40%. Furthermore, through the 1M and 2M first crossbeam 2 and second crossbeam 3, the modular crossbeam combination is realized, which significantly reduces the types of storage specifications and lowers management costs.

[0033] Reference Figure 1 , Figure 2 and Figure 4An installation assembly 4 is provided between the upper and lower ends of the supporting column 1. The installation assembly 4 includes a mounting base plate 41 and a column top 42. The upper surface of the mounting base plate 41 is fixedly connected to the bottom end of the supporting column 1. Installation through holes are provided at the four corners of the upper surface of the mounting base plate 41, wherein the inner wall size of the installation through holes is larger than the outer wall size of the mounting studs 44. The lower surface of the column top 42 is fixedly connected to the top end of the supporting column 1. The column top 42 is a flat-top conical steel component. An installation top plate 43 is fixedly connected to the upper surface of the column top 42. Four mounting studs 44 are fixedly connected to the upper surface of the installation top plate 43, located at the four corners of the upper surface of the installation top plate 43. The upper surface of the mounting base plate 41 is connected to the supporting column 1. A reinforcing rib 6 is fixedly connected between the outer surfaces of the column 1. A locking groove is provided at the center of the upper surface of the reinforcing rib 6. The inner wall size of the locking groove is adapted to the end size of the first crossbeam 2 and the second crossbeam 3. By installing the assembly 4 and the reinforcing rib 6, and using the mounting base plate 41 with mounting through holes and the mounting top plate 43 with mounting studs 44, it is convenient to flexibly assemble the corresponding number of supporting columns 1 according to the required height of the stacked steel bars. By combining the reinforcing rib 6 with the locking groove with the column top 42 with the flat-top conical structure, the peak stress at the node connecting the supporting column 1, the first crossbeam 2, and the second crossbeam 3 is reduced to below 60% of the material yield strength, thereby improving the stability and load-bearing capacity of the overall steel bar stacking structure.

[0034] Working principle: In use, the 1-meter first crossbeam 2 and the 2-meter second crossbeam 3 are combined to meet more than 95% of the standard steel bar length requirements. The through-hole connecting plate 52 on the supporting column 1 is connected to the assembly through-hole 51 on the first crossbeam 2 and the second crossbeam 3 via bolt assembly 7. This pure bolt connection design completely avoids welding, reducing construction costs and safety risks. The anti-slip texture 53 on the surface of the through-hole connecting plate 52, together with the bolt assembly 7, forms a dual anti-slip mechanism, improving node reliability by 40%. The 1-meter and 2-meter first crossbeam 2 and the second crossbeam 3 effectively... The modular beam assembly significantly reduces the variety of storage specifications and lowers management costs. At the same time, based on the required stacking height of the steel bars, the mounting through holes on the mounting base plate 41 and the mounting studs 44 on the mounting top plate 43 are spliced ​​together and locked with nuts. The corresponding number of support columns 1 can be flexibly assembled. By setting the reinforcing ribs 6 with snap-fit ​​grooves and the column tops 42 with flat-top conical structures, the peak stress at the nodes between the support columns 1, the first beam 2 and the second beam 3 is reduced to below 60% of the material yield strength, thereby improving the stability and load-bearing capacity of the overall steel bar stacking structure.
