Detailed Implementation

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example

[0031] This invention provides a prefabricated equipment room for railways, see [link / reference]. Figure 1 The system includes steel beams and a foundation. A wall is constructed between the steel beams 800 and the foundation 900. The wall includes an outer assembly plate 100 and an inner assembly plate 200 disposed between the steel beams 800 and the foundation 900. A Faraday cage 300 and an insulation layer 400 are disposed between the outer assembly plate 100 and the inner assembly plate 200. Through the prefabricated outer assembly plate 100 and inner assembly plate 200, the overall wall installation is simple and fast, while simultaneously meeting the requirements for electromagnetic shielding and thermal insulation.

[0032] The upper end of the Faraday cage 300 is connected to the lightning protection strip on the steel beam 800, and the lower end of the Faraday cage 300 is fixedly connected to the grounding grid in the foundation 900; thus ensuring the electromagnetic shielding requirements.

[0033] The insulation layer 400 is located on the side of the Faraday cage 300 near the inner assembly plate 200, and the insulation layer 400 and the outer assembly plate 100 are connected by expansion nails 410.

[0034] See Figures 2-4 Specifically, a first fixing component 500 is installed between the outer assembly plate 100 and the steel beam 800, and a positioning component 600 is installed between the outer assembly plate 100 and the foundation 900. A second fixing component 700 is installed between the inner assembly plate 200 and the steel beam 800. Multiple inner assembly plates 200 are sequentially installed along the length of the steel beam 800, and a reinforcing structure 240 is installed between adjacent inner assembly plates 200. Through the installation of the first fixing component 500, the positioning component 600, the second fixing component 700, and the reinforcing structure 240, the wall has the characteristics of earthquake resistance and crack prevention.

[0035] The outer assembly plate 100 has a mounting hole 110 on one side near the inner assembly plate 200. A through fixing hole 120 is formed at the bottom of the mounting hole 110, and the diameter of the mounting hole 110 is larger than the diameter of the fixing hole 120. One end of the first fixing component 500 is connected to the steel beam 800, and the other end is connected to the fixing hole 120. Concrete mortar blocks 130 are filled into the mounting hole 110. By using the mounting hole 110, the first fixing component 500 is connected to the outside, while the outer end is filled with concrete mortar blocks 130. This allows the first fixing component 500 to connect to the outside but not to the inside of the outer assembly plate 100, thus securing the outer assembly plate 100 while avoiding thermal bridging.

[0036] The first fixing component 500 includes an angle steel 510 and a hook bolt 520.

[0037] An installation opening 140 is provided at one end of the outer assembly plate 100 near the steel beam 800, and a fixing hole 120 is located within the installation opening 140. One side of the angle steel 510 is fixed to the steel beam 800, and the other end is fitted into the installation opening 140. One end of the hook bolt 520 passes through the fixing hole 120 and is located within the installation hole 110. A locking nut 530 is provided on the section of the hook bolt 520 located in the installation hole 110. The bent end of the hook bolt 520 is located within the installation opening 140 and is fixedly connected to the angle steel 510. A first concrete mortar layer 540 is provided between the outer assembly plate 100 and the steel beam 800. Through the installation opening 140, after installation, the hook bolt 520 and the angle steel 510 are both located within the installation opening 140, facilitating the subsequent laying of the first concrete mortar layer 540. At the same time, other layers of structure are laid on the outer side.

[0038] The outer assembly panel 100 includes an adjacent first outer assembly panel 100a and a second outer assembly panel 100b. A first limiting groove 150 is formed on the vertical side of the first outer assembly panel 100a near the second outer assembly panel 100b. A first limiting ridge 160 is integrally formed on the vertical side of the second outer assembly panel 100b near the first outer assembly panel 100a. The first limiting ridge 160 and the first limiting groove 150 cooperate with each other, and a second concrete mortar layer 170 is provided between the first outer assembly panel 100a and the second outer assembly panel 100b. This arrangement improves the connection strength between the two panels after installation and enhances the thermal insulation effect.

[0039] The positioning component 600 includes a positioning block 610 integrally formed on the foundation 900. Positioning holes 180 are spaced apart on the side of the outer assembly plate 100 near the foundation 900, and these holes 180 engage with the positioning block 610. A third concrete mortar layer 620 is provided between the outer assembly plate 100 and the foundation 900. The positioning block 610 includes a first reinforcing rib 611 and an outer concrete block 612. Several first reinforcing ribs 611 are provided, with one end of each rib located inside the foundation 900 and the other end located inside the concrete block 612. Through the cooperation of the positioning component 600 and the upper first fixing component 500, the connection strength between the outer assembly plate 100 and the steel beam 800 and the foundation 900 is greatly improved.

[0040] See Figure 5-Figure 9 The inner assembly plate 200 has a reinforcing groove 280 at one end near the steel beam 800.

[0041] The second fixing component 700 includes a second reinforcing rib 710, a third reinforcing rib 720, and a fourth concrete mortar layer 730. One end of the second reinforcing rib 710 is embedded inside the inner assembly plate 200, and the other end is located in the reinforcement groove 280. Multiple third reinforcing ribs 720 are fixedly connected along the length of the steel beam 800, and the other end of the third reinforcing rib 720 is located in the reinforcement groove 280. The fourth concrete mortar layer 730 is laid between the steel beam 800 and the inner assembly plate 200, and the second reinforcing rib 710, the third reinforcing rib 720, and the reinforcement groove 280 are located within the fourth concrete mortar layer 730. The installation of the second reinforcing rib 710, the third reinforcing rib 720, and the fourth concrete mortar layer 730 improves the connection strength between the inner assembly plate 200 and the steel beam 800, ensuring the seismic resistance of the inner assembly plate 200 during operation and greatly improving the safety of the wall structure.

[0042] The adjacent inner assembly panels 200 include a first inner assembly panel 200a and a second inner assembly panel 200b.

[0043] A second limiting groove 210 is provided on the vertical side of the first inner assembly plate 200a near the second inner assembly plate 200b, and a second limiting ridge 220 is provided on the vertical side of the second inner assembly plate 200b near the first inner assembly plate 200a; the second limiting ridge 220 is fitted into the second limiting groove 210, and a fifth concrete mortar layer 230 is laid between the first inner assembly plate 200a and the second inner assembly plate 200b.

[0044] The reinforcing structure 240 includes a U-shaped connecting rod 241. A first connecting hole 242 and a first connecting groove 243 are provided on the side of the first inner assembly plate 200a away from the outer assembly plate 100. One end of the first connecting groove 243 is connected to the first connecting hole 242, and the other end passes through the end face where the second limiting groove 210 is located. A second connecting hole 244 and a second connecting groove 245 are provided on the side of the second inner assembly plate 200b away from the outer assembly plate 100. One end of the second connecting groove 245 is connected to the second connecting hole 244, and the other end passes through the end face where the second limiting rib 220 is located. The first connecting groove 243 and the second connecting groove 245 are located at the same horizontal height. The two ends of the U-shaped connecting rod 241 are respectively fitted into the first connecting hole 242 and the second connecting hole 244, and the middle part of the U-shaped connecting rod 241 is located in the first connecting groove 243 and the second connecting groove 245.

[0045] The fifth concrete mortar layer 230 covers the reinforced structure 240. By embedding U-shaped connecting rods 241 in the fifth concrete mortar layer 230, after construction is completed, they are connected and fixed by the inside of the fifth concrete mortar layer 230, which not only improves the connection strength of the first inner assembly plate 200a and the second inner assembly plate 200b, but also reduces the risk of cracking of the fifth concrete mortar layer 230.

[0046] Locking holes 250 are provided at the top and bottom of the inner assembly plate 200. Pipe clamps 260 are provided at the locking holes 250. Pipe clamps 260 include locking tubes 261 inserted into the locking holes 250 and clamping plates 262 connected to the locking tubes 261. The clamping plates 262 are fixedly connected to the steel beams 800 or the foundation 900.

[0047] During the installation of the inner assembly panel 200, it is secured using pipe clamps 260. A sixth layer of concrete mortar 270 is provided at the bottom of the inner assembly panel 200.

[0048] This invention provides a prefabricated railway equipment room, comprising an outer assembly panel 100 and an inner assembly panel 200, with a Faraday cage mesh 300 and an insulation layer 400 placed between them. The prefabricated outer and inner assembly panels 100 and 200 simplify the overall wall installation, allowing for rapid assembly while simultaneously meeting the requirements for electromagnetic shielding and thermal insulation. Furthermore, during the installation of the outer and inner assembly panels 100 and 200, the inclusion of a first fixing component 500, a positioning component 600, a second fixing component 700, and a reinforcing structure 240 enhances the connection strength between the outer and inner assembly panels 100 and 200, giving the wall earthquake resistance and crack prevention properties, while also improving the thermal insulation effect of the equipment room.
