[0012] The ground keels are fixed to the ground, and the ground keels are multiple and form a rectangular structure;

[0013] There are a plurality of columns, and the bottoms of the columns are connected to the ground keels;

[0014] There are multiple ring beams arranged on the top of the columns, and the ring beams form a rectangular structure similar to the ground keel;

[0015] There are a plurality of cross beams, each of which is arranged in a rectangular structure surrounded by the ring beam, and both ends of the cross beam are respectively connected to the ring beam.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] A stainless steel fully welded wall system for a biosafety laboratory in this embodiment, such as Figure 1-8 As shown, it includes a keel frame 1, a stainless steel honeycomb composite panel 2 and a corner strip 3;

[0041] The interior of the keel frame 1 forms a laboratory space;

[0042] The stainless steel honeycomb composite panel 2 is laid on the inner wall and top surface of the laboratory space enclosed by the keel frame 1 to form the wall and top surface of the laboratory;

[0043] like Figure 6 and 7 As shown, the corner strip 3 is an arc-shaped structure, and the corner strip 3 is arranged at the intersection of two adjacent walls, the intersection of the wall and the ground, and the intersection of the wall and the top surface;

[0044] like Figure 4 As shown, the stainless steel honeycomb composite panel 2 includes a front panel 21, a honeycomb core 22 and a rear panel 23; the front panel 21 is arranged on one side of the honeycomb core 22, and the rear panel 23 is arranged on the other side of the honeycomb core 22; the edges of the front panel 21 protrude from the honeycomb core 22, and the edges of the rear panel 23 are flush with the edges of the honeycomb core 22; Figure 8 As shown, the front panels 21 of two adjacent stainless steel honeycomb composite panels are butt-jointed and fully welded; Figure 5 and 6 As shown, the front panels of the two stainless steel honeycomb composite panels that form the inner or outer corners of the wall are respectively connected to the corner strips by full welding, and the rear panels of the stainless steel honeycomb composite panels are welded and fixed to the keel frame to form a flat and airtight stainless steel fully welded wall system.

[0045] The stainless steel honeycomb composite panel 2 is formed by compounding the front panel 21, the honeycomb core 22 and the back panel 23 into an integrated panel through a two-component polyurethane adhesive. Therefore, after the stainless steel honeycomb composite panel 2 is laid on the keel frame 1, the front panel 21 is reinforced by the honeycomb core 22 on its back, so the front panel 21 has a higher flatness and a higher strength of the panel surface, is not easy to deform, and is not easy to bulge in a negative pressure environment. Therefore, it can solve the problem that the current laboratory stainless steel wall is easy to bulge in a negative pressure environment; in addition, the stainless steel honeycomb composite panel 2 of the present invention also innovatively adopts a structure in which the edges of the front panel 21 protrude from the honeycomb core 22, so that the honeycomb core 2 2 can be embedded in the keel frame 1, and the raised parts around the front panel 21 can be closely attached to the keel frame 1, so that the front panels 21 of the two adjacent stainless steel honeycomb composite panels 2 can be butt-welded to the inner wall of the keel frame 1. Since there is no overlap on the entire wall surface, the wall surface is smoother and flatter, easier to clean, and sanitary dead corners are reduced. The butt joints of the front panels 21 are fixed by full welding, which can ensure better air tightness in the laboratory. Corner strips 3 are respectively provided at the junctions of the two adjacent walls, the junctions of the wall and the ground, and the junctions of the wall and the top surface, so that the junctions are arc-shaped structures, which are easy to clean and sterilize.

[0046] Furthermore, the rear panel 23 is connected to the keel frame 1 by welding.

[0047] The welded connection between the rear panel 23 and the keel frame 1 can fix the rear panel 23 and the honeycomb core 22 relative to the keel frame 1, thereby fixing the stainless steel honeycomb composite panel 2, so that the rear panel 23 and the honeycomb core 22 can provide better support for the front panel 21, further strengthen the front panel 21, and make the front panel 21 less likely to deform.

[0048] Furthermore, if Figure 1 As shown, the keel frame 1 includes a ground keel 11, a column 12, a ring beam 13 and a cross beam 14;

[0049] The ground keels 11 are fixed to the ground, and the ground keels 11 are multiple and form a rectangular structure;

[0050] There are a plurality of columns 12, and the bottoms of the columns 12 are connected to the ground keels 11;

[0051] The ring beams 13 are multiple and are arranged on the top of the columns 12. The ring beams 13 form a rectangular structure similar to the ground keels 11.

[0052] There are a plurality of cross beams 14 , each of which is disposed in a rectangular structure surrounded by the ring beam 13 , and both ends of the cross beam 14 are connected to the ring beam 13 respectively.

[0053] The ground keel 11 is installed on the ground, thereby fixing the entire laboratory to the ground. The columns 12 are installed on the ground keel 11. Multiple columns 12 form a wall frame, so that the stainless steel honeycomb composite panel 2 is laid on it to form the wall of the laboratory; the ring beam 13 is set on the top of the column 12 to form the top frame of the laboratory, and the cross beam 14 strengthens the top frame. The stainless steel honeycomb composite panel 2 is laid on it to form the top surface of the laboratory.

[0054] Furthermore, it includes a plurality of column reinforcement beams 15 and a plurality of secondary beams 16 . The column reinforcement beam 15 is arranged between two adjacent columns 12 , and the secondary beam 16 is arranged between two adjacent cross beams 14 and between the cross beam 14 and the ring beam 13 .

[0055] Installing a column reinforcement beam 15 between two adjacent columns 12 connects the columns 12, forming a unified structure. This reinforces the columns 12 and stabilizes the keel frame 1. Furthermore, the column reinforcement beam 15 supports the backside of the stainless steel honeycomb composite panel 2 on the wall. Similarly, the secondary beam 16 connects the crossbeams 14, thereby increasing the strength of the top frame and supporting the stainless steel honeycomb composite panel 2 on the top surface.

[0056] Furthermore, if Figure 2 As shown, the column 12 is connected to the ground keel 11 through the angle code 17, and the column 12 and the ground keel 11 are fixed by welding; the column 12 and the ring beam 13 are connected through the angle code 17, and the column 12 and the ring beam 13 are fixed by welding.

[0057] Furthermore, if Figure 3 As shown, each connection of the keel frame 1 is connected by mortise and tenon joints and fixed by welding.

[0058] This arrangement can achieve multiple fixed connections, making the overall strength of the keel frame 1 higher.

[0059] like Figure 7 As shown, the corner bar 3 includes an arc segment 31 and a straight segment 32 , and the straight segments 32 are respectively provided on both sides of the arc segment 31 . The corner bar 3 is fully welded to the front panel 21 of the stainless steel honeycomb composite panel 2 through the straight segments 32 .

[0060] By setting the straight line segment 32, the corner strip 3 can be made smoother when connected to the stainless steel honeycomb composite panel 2, and the straight line segment 32 and the front panel 21 of the stainless steel honeycomb composite panel 2 are both planar structures. Therefore, after the connection, the transition between the corner strip 3 and the front panel 21 is smoother.

[0061] Furthermore, the front panel 21 and the rear panel 23 are both made of stainless steel, and the honeycomb core 22 is made of aluminum alloy, thereby having good corrosion resistance.

[0062] Throughout this specification, reference to terms such as "one embodiment," "certain embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0063] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
