[0048] For better explaining the present utility model for easy understanding, the technical solutions and effects of the present utility model will be described in detail below in conjunction with the drawings through specific implementation manners.

[0049] As Figure 1-Figure 2 shown, a prefabricated aluminum alloy reactor cabin body includes a frame 1, a roof 2 on the top of the frame 1, a prefabricated grille 3 on the side of the frame 1, a bottom plate 4 at the bottom of the frame 1, and a hatch door 5 assembled on the prefabricated grille 3.

[0050] As Figure 3-Figure 7 shown, the frame 1 is assembled by angle aluminum bolts and includes a side围 frame composed of 11 columns 11 and 9 first keels 12, a front and rear围 frame composed of a second keel 13 and diagonal braces 14, a ceiling skeleton composed of longitudinal beams and cross beams, and a bottom plate frame composed of bottom diagonal braces 14, longitudinal beams and cross beams. Among them, the front and rear ends of the frame 1 are "mouth"-shaped closed structures, and the middle is a "U"-shaped closed structure, so as to improve the bearing capacity of the frame 1.

[0051] The second keel 13 of the front and rear围 frame is longitudinally arranged, and a plurality of diagonal braces 14 are arranged between the second keel 13 and the column 11. A plurality of closed triangular frame structures are formed by the second keel 13 and the diagonal braces 14 to increase the stability of the frame 1.

[0052] The ceiling skeleton is formed by connecting longitudinal beams and cross beams with angle aluminum bolts, and the whole forms a closed "eye"-shaped structure.

[0053] The bottom plate frame includes an external rectangular frame surrounded by longitudinal beams and cross beams and a plurality of longitudinal beams arranged in the rectangular frame. Every two of the plurality of longitudinal beams in the rectangular frame are in a group, and a bottom diagonal brace is arranged between the two longitudinal beams in each group. The bottom diagonal braces are arranged at the front, middle, and rear positions of the important bearing area, that is, the bottom plate frame, to increase the bearing capacity of the bottom and ensure the reliability of use.

[0054] The frame 1 only adopts two types of profile sections, which reduces the mold cost, and the quality is easy to control, the processing efficiency is high, and the cost can be effectively reduced. Among them, as Figure 8-Figure 9 shown, the profiles of the column 11, cross beam, and longitudinal beam adopt a "device"-shaped multi-chamber closed structure section, which has strong bending and torsion resistance; as Figure 10-11As shown, the first keel 12, the second keel 13, the diagonal support 14 and the bottom diagonal support adopt a simple "mouth" shaped cross section. Such a combination can ensure the overall wind load, snow load and earthquake resistance of the frame 1 while ensuring the lightweight goal.

[0055] like Figure 12-Figure 17 As shown, the roof 2 is formed by the cover plate 21 and the sheet metal beam 22 being buckled on the sides and connected by self-tapping screws to ensure its sealing. The cover plate 21 and the sheet metal beam 22 adopt a trapezoidal slope design, and the side section is trapezoidal, which is convenient for rain and snow and other roof coverings to fall down along the slope without easy accumulation, reducing the load of the roof 2 and ensuring the safe use of the roof 2.

[0056] like Figure 18-19 As shown, the bottom plate 4 is formed by welding a plurality of profile plates arranged side by side, and the plurality of profile plates are mutually positioned by means of concave surfaces 411 and convex surfaces 412. The bottom plate 4 formed after welding is assembled on the frame 1 by self-tapping screws.

[0057] The assembled grid 3 includes a plurality of grid units of different lengths. Fig. 20 As shown, the grid units are assembled to the frame 1 by self-tapping screws.

[0058] like Figure 21-23 As shown, the hatch 5 is formed by welding a plurality of hollow profiles side by side and is connected to the frame 1 by hinge bolts. The hatch of this structure can improve the dent resistance of the hatch 5 and increase the service life.

[0059] Finite element analysis is performed on the working state of the assembled aluminum alloy reactor cabin provided in this embodiment, and the stress cloud diagram is as follows: Fig.24 As shown, the displacement cloud diagram is Fig.25 As shown, the results show that the assembled aluminum alloy reactor cabin meets the strength and stiffness requirements.
