DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0034] like Figures 1 to 11 As shown, a preferred embodiment of the assembled wall structure for a substation of the present invention includes a support frame 1, a first flame retardant board 21, a second flame retardant board 22 and a plurality of insulation boards 3;

[0035] The support frame 1 includes an outer frame 11, a plurality of transverse support rods 12 and vertical support rods; the outer frame 11 has a receiving space, each transverse support rod 12 and each vertical support rod is cross-fixed in the receiving space, and the receiving space is divided into a plurality of sub-receiving spaces; the ends of the transverse support rods 12 and each vertical support rod are welded and fixed to the outer frame 11, and the transverse support rods 12 and each vertical support rod are welded to form a grid-like reinforcement structure. The setting of the grid-like reinforcement structure enhances the strength of the support frame 1; Figure 11As shown, the distribution density of each vertical support rod gradually decreases from both sides of the width direction of the outer frame 11 to the center of the width direction of the outer frame 11; the edge strength of the support frame 1 is crucial to improving the bending and compressive strength of the support frame 1. By increasing the arrangement density of the vertical support rods at the edge of the outer frame 11, the support strength of the support frame 1 can be increased. The arrangement density of the vertical support rods at the center of the width direction of the outer frame 11 is lower than that at the edge, which can reduce the amount of vertical support rods used and reduce the overall weight of the support frame 1. Figure 1 As shown, the width direction of the support frame 1 refers to Figure 1 In the first direction X, the vertical support rods are sparsely distributed at the center of the width direction of the outer frame 11, and are densely distributed at the positions on both sides of the width direction of the outer frame 11; each sub-accommodation space is filled with an insulation board 3; the insulation board 3 is an insulation rock wool board, and the insulation board 3 is arranged in the sub-accommodation space. In the thickness direction of the insulation board 3, the support frame 1 and the insulation board 3 at least partially overlap, and the internal space of the support frame 1 can be used to install the insulation board 3, so that the thickness of the prefabricated assembled wall can be set thinner and have better insulation ability; the first flame retardant board 21 is fixedly covered on one side of the support frame 1 in the thickness direction, and the second flame retardant board 22 is fixedly covered on the other side of the support frame 1 in the thickness direction, so that the assembled wall structure for the substation of this embodiment has better waterproof performance. Among them, the first flame retardant board 21 and the second flame retardant board 22 are both fiber cement boards. The first flame retardant board 21 and the second flame retardant board 22 are connected to the outer frame 11 and the horizontal support rod 12 and the vertical support rod by bolts. The thickness of the first flame retardant board 21 and the second flame retardant board 22 is 10mm to 15mm. The first flame retardant board 21 and the second flame retardant board 22 play the role of waterproof, fireproof and flame retardant. In addition, the fiber cement board has good insulation properties and can meet the insulation requirements of the substation structure.

[0036] In this embodiment, the prefabricated wall structure for a substation further includes a decorative panel 4, which is fixedly attached to the outside of the first flame-retardant panel 21 and / or the second flame-retardant panel 22. The decorative panel 4 is made of fiber cement and can be constructed by assembling multiple panels. To further enhance waterproof performance, the joints of the decorative panels 4 are provided with tongue-and-groove waterproof sills.

[0037] In this embodiment, a lifting lug is fixed to the upper end of the outer frame 11. The provision of the lifting lug facilitates the lifting of the prefabricated wall for the substation during installation; specifically, there are two lifting lugs, which are spaced apart along the width direction of the outer frame 11.

[0038] In this embodiment, the assembled wall structure for the substation further includes a top beam 51 and a bottom beam 52. The top beam 51 is fixed to the top of the main structure of the substation, and the bottom beam 52 is fixed to the bottom of the main structure of the substation. The upper end of the support frame 1 is detachably connected to the top beam 51, and the lower end of the support frame 1 is detachably connected to the bottom beam 52. Specifically, the top beam 51 and the bottom beam 52 are both made of I-beams. The assembled wall structure for the substation includes a first connecting member 6. The first connecting member 6 includes a first connecting plate 61 and a second connecting plate 62 fixed vertically. The first connecting plate 61 is fastened to the upper end of the support frame 1, and the second connecting plate 62 is fastened to the top beam 51. The first connecting plate 61 and the second connecting plate 62 constitute angle steel, wherein, in order to improve the connection strength of the first connecting member 6, triangular ribs are welded and fixed to the ends of the first connecting plate 61 and the second connecting plate 62.

[0039] Furthermore, the first connecting plate 61 has a first connecting hole 611, which is a rectangular hole and is arranged vertically along its length. The prefabricated wall structure for the substation also includes a first connecting bolt 71, which is passed through the first connecting hole 611 and connects the upper end of the support frame 1 and the first connecting plate 61. Specifically, a washer is provided between the nut of the first connecting bolt 71 and the first connecting plate 61. Tightening the first connecting bolt 71 can connect the first connecting member 6 to the support frame 1. The width of the first connecting hole 611 is slightly larger than the diameter of the first connecting bolt 71. In the event of an earthquake, the first connecting bolt 71 can generate a certain amount of friction and sliding in the first connecting hole 611, thereby dissipating energy and improving the seismic performance of the prefabricated wall structure for the substation.

[0040] In this embodiment, the prefabricated wall structure for the substation includes a second connector 8, which includes a third connector plate 81 and a fourth connector plate 82, which are vertically fixed. The third connector plate 81 is fastened to the lower end of the support frame 1, and the fourth connector plate 82 is fastened to the bottom beam 52. Because the third and fourth connector plates 81, 82 are vertically fixed, during high-level earthquakes, the intersection of the third and fourth connector plates 81, 82 can undergo plastic deformation and dissipate energy. This allows the connection node between the prefabricated wall structure for the substation and the bottom beam 52 to dissipate energy, reducing the probability of deformation of the support frame 1 during an earthquake. After the earthquake, the second connector 8 can be replaced.

[0041] The support frame 1 has a mounting hole at its lower end, through which a second connecting bolt 72 is passed. The second connecting bolt 72 connects to the third connecting plate 81. The fourth connecting plate 82 is connected to the bottom beam 52 via a third connecting bolt 73. The number of second connecting bolts 72 connected to the same third connecting plate 81 is greater than the number of third connecting bolts 73 connected to the same fourth connecting plate 82. The transverse support rods 12 and the vertical support rods are both steel pipes, and the outer frame 11 is also welded from steel pipes, with the mounting holes provided in the steel pipes. In this embodiment, a plurality of second connecting bolts 72 are connected to each third connecting plate 81, and a third connecting bolt 73 is connected to each fourth connecting plate 82. This arrangement ensures that, in the event of an earthquake, the connection strength between the third connecting plate 81 and the support frame 1 is greater than the connection strength between the fourth connecting plate 82 and the bottom beam 52. This ensures that deformation during an earthquake occurs at the fourth connecting plate 82 and at the junction of the fourth connecting plate 82 and the third connecting plate 81. Deformation of the mounting hole will only occur during a particularly strong earthquake. Keeping the installation hole intact facilitates replacement of the second connecting member 8 and connection of a new second connecting member 8 after a normal earthquake occurs.

[0042] Furthermore, the prefabricated wall structure for the substation also includes a fifth connecting plate 9, a decorative plate 4 connected to the outer side of the second flame retardant plate 22, and the fifth connecting plate 9 is attached to the outer side of the first flame retardant plate 21; at least two third connecting plates 81 are attached to the side of the fifth connecting plate 9 facing away from the first flame retardant plate 21, and the third connecting bolts 73 connected to the third connecting plates 81 attached to the same fifth connecting plate 9 are all passed through the fifth connecting plate 9. Two adjacent second connecting members 8 are defined as a group of second connecting members 8, and all third connecting bolts 73 connected to a group of second connecting members 8 are defined as a group of third connecting bolts 73. A group of third connecting bolts 73 are all passed through the fifth connecting plate 9. After an earthquake occurs, the fifth connecting plate 9 can couple a group of third connecting bolts 73, so that the force exerted by each third connecting bolt 73 on the wall of each mounting hole can be balanced, thereby preventing the wall of a certain mounting hole from being deformed due to excessive force.

[0043] In this embodiment, the fifth connecting plate 9 is an I-shaped plate body, and the fifth connecting plate 9 includes a connecting portion and four protrusions protruding from the connecting portion. Two third connecting bolts 73 are connected to a third connecting plate 81. There are a total of four third connecting bolts 73 in a group. The four third connecting bolts 73 are respectively passed through the four protrusions of the fifth connecting plate 9.

[0044] In summary, the prefabricated wall structure for a substation of the present invention comprises a support frame 1, a first flame retardant panel 21, a second flame retardant panel 22 and a plurality of insulation panels 3; the support frame 1 comprises an outer frame 11, a plurality of transverse support rods 12 and a vertical support rod; the outer frame 11 has a accommodating space, each transverse support rod 12 and each vertical support rod is cross-fixed in the accommodating space, and the accommodating space is divided into a plurality of sub-accommodating spaces; the distribution density of each vertical support rod gradually decreases from both sides of the width direction of the outer frame 11 to the center of the width direction of the outer frame 11, and the edge strength of the outer frame 11 is relatively high, which not only ensures the vertical strength of the wall structure, but also makes the overall weight of the support frame 1 relatively small, and each sub-accommodating space is filled with an insulation panel 3 to achieve insulation of the wall structure, and the first flame retardant panel 21 is fixedly covered on one side of the support frame 1 in the thickness direction, and the second flame retardant panel 22 is fixedly covered on the other side of the support frame 1 in the thickness direction; the prefabricated wall structure for a substation of the present invention has high strength, is lighter in weight than existing concrete walls, and is easy to install.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
