Description

Technical Field

[0001] This invention relates to the field of wall panel assembly and disassembly structures, and in particular to a detachable wall panel system for a steel structure substation and its assembly and disassembly method. Background Technology

[0002] With the continuous development of power systems and the acceleration of urbanization, substations, as important hubs in the power transmission and distribution system, are seeing continuous improvement in their construction standards and operation management levels. In recent years, standardized design concepts have been widely applied in substation construction, especially the promotion and application of integrated external wall systems. This has not only improved the overall aesthetics and structural safety of substations, but also effectively reduced the impact of noise on the surrounding environment by integrating sound-absorbing materials, thus meeting relevant environmental protection and energy-saving requirements.

[0003] However, existing integrated exterior wall systems are mostly non-removable or difficult-to-remove structures, with the wall panels firmly connected to the main structure, making rapid, non-destructive disassembly and reuse difficult. In subsequent substation expansion and renovation projects, as well as production technology upgrades, it is often necessary to temporarily remove parts of the exterior wall to facilitate the transportation, installation, or replacement of large equipment. Existing wall structures generally suffer from the following problems in such scenarios: First, the wall panel structure is irreversibly disassembled, making it difficult to restore to its original state after removal and preventing reuse, resulting in material waste and increased costs. Second, the disassembly and reassembly process is cumbersome, requiring a large amount of manual labor and machinery, leading to a long construction period and impacting the normal operation of the substation and project progress. Third, the wall panel and its connectors are easily damaged during demolition, reducing structural safety and subsequent reliability. Furthermore, the existing external wall system, after reinstallation, cannot guarantee its sealing performance, easily leading to problems such as water seepage and air leakage, affecting the substation's operating environment and equipment safety.

[0004] With the increasing demand for prefabricated buildings and efficient construction in new infrastructure projects, existing exterior wall systems are struggling to meet diverse needs such as rapid disassembly and assembly, reuse, and efficient sealing. Especially in the context of substations requiring frequent equipment replacements, technology upgrades, or capacity expansions, achieving efficient, non-destructive disassembly and assembly and reuse of exterior walls has become a pressing technical challenge.

[0005] For example, the invention disclosed in CN111779162A discloses a method for manufacturing a modular steel structure substation with detachable walls. By adding detachable auxiliary keel, the overall assembly and disassembly of some areas of the exterior wall can be achieved. However, it requires pre-setting the detachable area, and only wall panels in specific areas are allowed to be disassembled afterward, which limits the design of renovation and expansion projects. In addition, the special keel in the detachable area is different from the standard keel, which has a certain impact on cost and installation efficiency.

[0006] The invention disclosed in CN111636638A is a detachable wall panel system and its installation and disassembly methods. The wall panel position is fixed by fasteners passing through the wall panel, and the detachable connection between the wall panels is achieved by using a rotatable pressure plate. However, this wall panel system is not suitable for prefabricated steel structures.

[0007] The invention disclosed in CN111926949A presents a connection structure and construction method for prefabricated wall panels and assembled steel frame beams. The wall panels are indirectly connected to the steel beams using L-shaped connectors and bolts. While this connection structure facilitates the disassembly and installation of the wall panels, disassembly requires tightening a large number of bolts from the inside, making it relatively cumbersome.

[0008] Therefore, there is an urgent need to develop a new type of substation exterior wall system that is structurally sound, easy to assemble and disassemble, reusable, and has good sealing performance, in order to meet the actual needs of substations in various application scenarios such as renovation and expansion, and production technology upgrades, reduce construction costs, reduce resource waste, and improve the operational safety and management convenience of substations. Summary of the Invention

[0009] The purpose of this invention is to overcome the defects of the prior art and provide a detachable wall panel system for steel structure substations that is easy to assemble and disassemble, reusable, and has good sealing performance, as well as its assembly and disassembly method.

[0010] The objective of this invention can be achieved through the following technical solutions: A removable wall panel system for a steel structure substation includes: The upper Z-shaped connector and the lower Z-shaped connector are respectively connected to the upper and lower ends of the steel beam of the main steel structure, and a gap is left between the upper Z-shaped connector and the lower Z-shaped connector. The wall panel, located on one side of the upper Z-type connector and the lower Z-type connector, has a slot for installing the H-type clip, and the four inner corners have notches for the H-type clip to rotate. The H-type fastener has an H-shaped cross-section. The upper and lower ends are respectively installed with Z-type connectors and wall panels through slots on the wall panels, as well as the lower Z-type connector and wall panel. The H-type fastener has a round hole and a cross groove concentric with the round hole on the side away from the steel beam. A sealing plate is provided to seal the outside of the gap and has a connecting rod extending toward the H-shaped clip. The connecting rod mates with the circular hole and has a positioning piece that mates with the cross groove.

[0011] Furthermore, the bottom edge of the upper Z-shaped connector and the top edge of the lower Z-shaped connector are arranged parallel to each other, forming the gap between them; the bottom edge of the upper Z-shaped connector and the corresponding wall plate are located in the upper groove of the H-shaped clip, and the top edge of the lower Z-shaped connector and the corresponding wall plate are located in the lower groove of the H-shaped clip.

[0012] Furthermore, the H-shaped clamp includes a left clamping claw, a right clamping claw, and a middle connecting part. The middle connecting part connects the left clamping claw and the right clamping claw respectively, forming an H-shaped structure. The upper and lower ends of the right clamping claw are respectively located in the corresponding slots of the wall panel. The upper end of the left clamping claw, the right clamping claw, and the middle connecting part forms the upper groove, and the lower end forms the lower groove.

[0013] Furthermore, the lower Z-shaped connector is provided with a triangular plate for limiting and positioning the H-shaped clip, and the triangular plate is connected to the bottom edge and the middle vertical edge of the lower Z-shaped connector.

[0014] Furthermore, the wall panel has an outer notch on the outer side of one end near the gap, and the sealing plate has an outer protrusion that matches the outer notch for positioning and enhancing sealing performance.

[0015] Furthermore, the sealing plate is provided with a heat insulation layer and a sound absorption layer.

[0016] Furthermore, the steel beam is an I-shaped structure, including a top horizontal plate, a middle vertical plate, and a bottom horizontal plate. The middle vertical plate connects the top horizontal plate and the bottom horizontal plate respectively. The top of the top horizontal plate supports the top edge of the upper Z-shaped connector, and the top of the bottom horizontal plate supports the bottom edge of the lower Z-shaped connector.

[0017] The present invention also provides a method for disassembling and assembling a detachable wall panel system for a steel structure substation as described above, including an installation process and a disassembly process, wherein the installation process includes the following steps: S101: Connect the upper Z-shaped connector and the lower Z-shaped connector to the steel beam, wherein the lower Z-shaped connector is installed on the bottom wall panel; S102: Place the wall panel to be installed on the upper Z-shaped connector and keep it vertical; S103: Slide the H-type clip horizontally into the gap between the two wall panels, and use a tool to drive the H-type clip through the cross groove and round hole to rotate it to a vertical position at the corner of the wall panel, and slide it towards the center of the wall panel along the groove on the wall panel. S104: Push the sealing plate into the gap between the two wall panels so that the connecting rod is inserted into the round hole of the H-type clip, and use the positioning piece to ensure that the sealing plate is installed in place; S105: Repeat steps S101-S104 to complete the installation of the remaining wall panels.

[0018] Furthermore, step S102 also includes: after placing the wall panel to be installed on the upper Z-shaped connector, a pad is placed between the bottom wall panel and the wall panel to be installed to transfer the weight of the wall panel to be installed to the bottom wall panel. Step S104 also includes: removing the installed pad after the sealing plate is installed in place.

[0019] Furthermore, the disassembly process includes the following steps: S201: Remove the sealing plates at the top and bottom of the wall panel to be disassembled; S202: Use a tool to insert into the cross groove and round hole of the H-type clip, drive the H-type clip to slide to the corner of the wall panel and rotate it to be horizontal before taking it out; S203: Remove the wall panel to be dismantled; S204: Repeat steps S201-S203 until all wall panels to be removed are removed; S205: Install H-type clips and sealing plates on the top of the remaining wall panels.

[0020] Compared with the prior art, the present invention has the following advantages: (1) The present invention innovatively proposes the setting of H-type fasteners. The H-type fasteners are connected to the steel beams of the main steel structure through the upper and lower Z-type connectors on the one hand, and support the upper and lower wall panels on the other hand, so as to realize the upper and lower installation and fixation of the wall panels. Furthermore, the sealing plate is set to be installed and positioned with the round hole and cross groove on the H-type fasteners. While preventing the H-type fasteners from moving, it transmits the pressure between the wall panels and avoids the exposure of the internal structure. It prevents rainwater from entering while keeping the external wall flat and beautiful. The main solution of this invention can realize the removal and reinstallation of wall panels in any area. It is convenient to remove and install, and facilitates the replacement of damaged wall panels. It meets the requirements of substation renovation and expansion projects and production technology transformation projects to dismantle the outer wall in order to transport equipment and then reinstall it completely.

[0021] (2) The present invention provides grooves and round holes on the H-type card, and can achieve efficient disassembly and assembly with the use of specific tools, saving time and effort.

[0022] (3) The present invention can set a heat insulation layer and a sound absorption layer inside the sealing plate, which can ensure the overall heat insulation and sound insulation effect of the substation.

[0023] (4) The present invention supports the upper wall panel on both sides by using H-shaped clips and sealing plates, which makes the force transmission path reasonable and the structure safe and stable. Attached Figure Description

[0046] Example 2 This embodiment provides a method for disassembling and assembling a detachable wall panel system for a steel structure substation as described in Embodiment 1, including an installation process and a disassembly process. The installation process includes the following steps: S101: Connect the upper Z-shaped connector 2 and the lower Z-shaped connector 3 to the steel beam 1. The lower Z-shaped connector 3 is installed on the bottom wall panel 5. The upper Z-type connector 2 and the lower Z-type connector 3 can be bolted or welded to the steel beam 1; for example, double-row high-strength bolts can be used to connect the upper Z-type connector 2 and the lower Z-type connector 3 to the steel beam 1 on the side away from the wall panel.

[0047] S102: Place the wall panel 5 to be installed on the upper Z-shaped connector 2 and keep it vertical; S103: As Figure 7 As shown, the H-type clip 4 is slid horizontally into the gap between the two wall panels 5, and the tool is used to drive the H-type clip 4 to rotate to the vertical position at the wall panel notch 51 of the wall panel 5 through the cross groove 41 and the round hole 42, and slide along the clip groove 52 on the wall panel 5 towards the middle of the wall panel 5 to the triangular plate 31 of the lower Z-type connector 3. S104: Push the sealing plate 6 into the gap between the two wall panels 5 so that the connecting rod 63 is inserted into the round hole 42 of the H-shaped clip 4, and use the positioning piece 62 and the outer protrusion 61 to ensure that the sealing plate 6 is installed in place. S105: Repeat steps S101-S104 to complete the installation of the remaining wall panels 5.

[0048] Preferably, step S102 further includes: after placing the wall panel 5 to be installed on the upper Z-shaped connector 2, a pad is placed between the bottom wall panel 5 and the wall panel 5 to be installed, so as to transfer the weight of the wall panel 5 to be installed to the bottom wall panel 5 and prevent damage to the connector. First, place a suitable height pad on the lower wall panel 5, then place the wall panel 5 to be installed. After the two H-shaped clips 4 slide into place, remove the pad.

[0049] Step S104 also includes: after the sealing plate 6 is installed in place, the pad is removed for reuse.

[0050] After the wall panels are installed, check and adjust the positions of all H-type clips and sealing plates to ensure they are securely fixed and waterproof.

[0051] The disassembly process includes the following steps: S201: As Figure 8 As shown, remove the sealing plates 6 on the top and bottom of the wall panel 5 to be disassembled; S202: Use a tool to insert the cross groove 41 and round hole 42 of the H-type clip 4, drive the H-type clip 4 to slide to the corner 51 of the wall panel and rotate it to be horizontal before taking it out; S203: Remove the wall panel to be disassembled 5; S204: Repeat steps S201-S203 until all wall panels to be removed are removed; S205: Reinstall the H-shaped clips 4 and sealing plates 6 above and below the demolished area onto the remaining wall panels to ensure the overall structural stability. Figure 9 As shown.

[0052] Preferably, in step S202, by setting a pad, the weight of the upper wall panel is temporarily transferred to the lower wall panel, reducing the friction between the H-type clip 4 and other components, facilitating the sliding of the H-type clip 4, and removing the pad after removal to achieve reuse.

[0053] First, insert a shim of appropriate height under the wall panel 5 to be removed, then slide and remove the two shims. After the wall panel 5 is removed, remove the shims.

[0054] After disassembling the wall panels, inspect all remaining structural components. If necessary, replace or reuse the H-type clips and sealing plates.
