[0002] The prior art with the publication number "CN109057077A" discloses a green building integrated prefabricated wall panel with an extended corner plate and a use method. The prefabricated wall panel of the green building is adjacent to the corner of the wall. The outer layer plate extends towards the corner of the wall. The end of the outer layer plate has a joint. The green building prefabricated wall panel with the outer layer plate extending towards the corner of the wall is connected to another green building prefabricated wall panel with the outer layer plate extending towards the corner of the wall. Cast-in-place concrete is formed between the outer layer plates of the two green building prefabricated wall panels. Cast-in-place concrete columns or cast-in-place concrete corners are formed. The cast-in-place concrete columns or cast-in-place concrete corners are integrated with the two green building prefabricated wall panels. The outer layer plate of the device extending towards the corner of the wall can be connected to any wall panel forming a building corner.

[0033] Please refer to Figures 1-7 The application provides a technical solution:

[0034] Embodiment one:

[0035] The assembled nuclear magnetic resonance shielding room is composed of a plurality of assembled floors 1, wall panels 2 and roof panels 3, the floor 1, the wall panel 2 and the roof panel 3 each include an outer decorative layer 4, an aerated concrete layer 5, a moisture-proof layer 6 and a copper mesh shielding layer 7, the outer decorative layer 4, the aerated concrete layer 5 and the moisture-proof layer 6 are symmetrically arranged on both sides of the copper mesh shielding layer 7, a plurality of floor panels 1 or roof panels 3 are assembled to form a protruding outer edge fence 8, the outer edge fence 8 is provided with an assembly hole 9, the upper and lower outer edge surfaces of the wall panel 2 are inserted and matched with the assembly hole 9 of the floor panel 1 or the roof panel 3 through the fixed insertion column 10, the insertion surfaces of the wall panel 2, the floor panel 1 and the roof panel 3 are spaced to form a horizontal pouring layer 11, and the horizontal inner and outer surrounding fences 12 and 13 are respectively bolted and fixed on the plate bodies on the inner and outer sides of the horizontal pouring layer 11;

[0036] The columnar stirrups 14 are fixedly installed on the left and right sides of the plurality of wall panels 2, the columnar stirrups 14 are arranged in a columnar form on the left and right sides of the copper mesh shielding layer 7, the columnar stirrups 14 of adjacent wall panels 2 are arranged in an up-down staggered form, the up-down staggered columnar stirrups 14 are fixed by the steel wire 15, the adjacent wall panels 2 are spaced to form a vertical pouring layer 16, and the vertical inner and outer surrounding fences 17 and 18 are further bolted and fixed on the plate bodies on the inner and outer sides of the vertical pouring layer 16;

[0037] The copper mesh reserved rolling grooves 19 are formed in the floor panel 1, the wall panel 2 and the roof panel 3, the copper mesh shielding layer 7 is reserved and rolled in the copper mesh reserved rolling groove 19, in the assembly process of the adjacent floor panel 1, wall panel 2 and roof panel 3, the copper mesh shielding layer 7 rolled in the copper mesh reserved rolling groove 19 is unfolded and extended into the connecting joint 20 of the adjacent plate body, so that the copper mesh shielding layer 7 between the adjacent plate bodies is overlapped;

[0038] The wall panel 2, the adjacent wall panel 2 and the floor panel 1 or the roof panel 3 form a T-shaped shielding escape area 21, the T-shaped shielding clamping plate 22 is installed on both sides of the T-shaped shielding escape area 21, and the lead casting hole 23 is formed in the T-shaped shielding clamping plate 22.

[0039] In this embodiment, the floor 1, wall 2 and roof 3 are assembled and formed by assembling, and due to the requirement of electromagnetic shielding of the nuclear magnetic resonance instrument, the copper mesh shielding layer 7 is embedded in the floor 1, wall 2 and roof 3, and the moisture-proof layer 6 is arranged on both sides of the copper mesh shielding layer 7, and the outer side of the moisture-proof layer 6 is the subject aerated concrete layer 5, and the outermost layer is the decorative layer 4. In order to ensure that the copper mesh shielding layer 7 can effectively wrap the inside while ensuring the strength of the main body of the assembled building, the concrete pouring scheme is determined in this embodiment, in order to solve the electromagnetic leakage condition of the concrete pouring joint, the copper mesh reserved winding groove 19 is arranged in the floor 1, wall 2 and roof 3, and the copper mesh shielding layer 7 in the adjacent copper mesh reserved winding groove 19 needs to be pulled out before concrete pouring, and is lapped in the connecting joint 20 on the other side, and then concrete pouring is carried out. This kind of special pouring method will face a technical problem that cannot be solved by existing assembled buildings, that is, the traditional wall 2 is bound with steel wire 15 by U-shaped hoop 14, but this binding method will cause the copper mesh shielding layer 7 to be unable to pass from one end of the copper mesh reserved winding groove 19 to the adjacent connecting joint 20. Therefore, in order to solve the above problem, the cylindrical hoop 14 is used instead of the U-shaped hoop, and the cylindrical hoop 14 on the adjacent wall 2 is arranged in a staggered manner and is bound in an up-down manner by the steel wire 15, and the cylindrical hoop 14 is arranged in a staggered manner on the adjacent wall 2, and the cylindrical hoop 14 is arranged in a staggered manner on the adjacent wall 2. Figure 3 and 4 This binding method will not affect the normal passing of the copper mesh shielding layer 7, and the up-down binding method also ensures the structural strength after pouring. In addition, referring to the drawings Figure 5 Since the copper mesh shielding layer 7 is wound in the copper mesh reserved winding groove 19, it is in a rectangular state when it is unfolded, so at the connecting position of the adjacent wall 2 and the floor 1 or the roof 3, a T-shaped shielding escape area 21 that cannot be covered by the copper mesh shielding layer 7 will appear. For this area, a T-shaped shielding clamp plate 22 is installed in this embodiment, and the surrounding copper mesh shielding layer 7 is clamped by the T-shaped shielding clamp plate 22. Finally, molten lead liquid is pumped into the copper mesh shielding layer 7, and after solidification, a lead plate mechanism connected with the copper mesh shielding layer 7 is formed, thereby realizing the electromagnetic shielding of the entire nuclear magnetic resonance shielding room, ensuring the structural strength and the electromagnetic shielding effect.

[0040] Embodiment two:

[0041] The horizontal inner and outer enclosing stops 12, 13, the vertical inner and outer enclosing stops 17 and 18 are also provided with pouring holes 24.

[0042] In this embodiment, the concrete is poured into the horizontal pouring layer 11 and the vertical pouring layer 16 through the pouring holes 24.

[0043] Embodiment three:

[0044] The column-shaped stirrup 14 is provided with evenly spaced stirrup grooves 25.

[0045] In this embodiment, by providing the stirrup grooves 25 on the column-shaped stirrup 14, the steel wire 15 can be prevented from sliding after being fixed, thereby ensuring the stability of the connection.

[0046] Embodiment Four:

[0047] The two T-shaped shielding clamping plates 22 are fixedly connected by bolts, and the T-shaped shielding clamping plate 22 on one side is further provided with a lead casting groove 26.

The wallboard 2 on one side of the connecting seam 20 is further provided with a pressing block 27 installed in a translational sliding manner. When the copper mesh shielding layer 7 in the copper mesh reserved rolling groove 19 of the adjacent wallboard 2 extends into the connecting seam 20, the translational sliding of the pressing block 27 can press and fix the overlapped copper mesh shielding layer 7 at the connecting seam 20.

[0049] The mechanism for driving the translational sliding of the pressing block 27 is a translational screw rod 28. The pressing block 27 is provided with a threaded hole matched with the translational screw rod 28. The translational screw rod 28 is provided with a sliding knob 29 on one side of the wallboard 2. The translational sliding of the pressing block 27 can be controlled by rotating the sliding knob 29.

[0050] In this embodiment, the overlapping pressing device between the adjacent copper mesh shielding layers 7 and the pressing method thereof are further disclosed, thereby maximizing the electromagnetic shielding effect.
