Description

Technical Field

[0001] This invention relates to the field of roof construction technology, and in particular to a substation roof assembly and prefabricated roof. Background Technology

[0002] As a critical hub in the power system, substation roof structures must meet stringent requirements for waterproofing, insulation, fire resistance, and structural strength. Traditionally, substation roofs are constructed using on-site cast-in-place concrete. While this method ensures structural integrity, it has the following significant drawbacks: 1. Long construction period and low efficiency: Cast-in-place concrete requires multiple steps such as formwork support, steel bar binding, pouring, vibration and curing. The procedures are complicated and interdependent, resulting in a long overall construction period, which is difficult to meet the needs of the rapid advancement of modern power construction.

[0003] 2. High dependence on manual labor and difficulty in quality control: Many processes rely on on-site manual operation, which is greatly affected by the skill level of workers, weather conditions and on-site management, making it easy for construction quality to fluctuate and making it difficult to guarantee the flatness, density and waterproofing performance of the roof.

[0004] 3. The material has a large self-weight, which puts high demands on the substructure: The concrete roof has a large self-weight, which increases the load on the substructure. This requires the cross-sections and reinforcement of load-bearing components such as beams and columns to be increased accordingly, thus increasing the cost of civil engineering and material consumption.

[0005] 4. Difficult to maintain and repair: Once cracks or local leaks appear on a concrete roof, repairs often require chiseling open the surface layer, which is a complex process, and the waterproofing durability after repair is difficult to match that of the original structure.

[0006] 5. Poor environmental friendliness: On-site wet operations generate dust and noise, consume a lot of water for maintenance, and produce a lot of construction waste, which does not meet the requirements of green construction and sustainable development.

[0007] Although some prefabricated roof components have emerged in recent years under the background of building industrialization, the following problems still exist in the specific application scenario of substations: the connection and sealing between components is insufficient, which can easily become a weak link in waterproofing; the integration and durability of the insulation layer and waterproof layer need to be improved; the overall fire resistance and wind uplift resistance of the roof need to be further strengthened; and the convenience and reliability of on-site assembly cannot yet meet the needs of rapid construction and long-term operation and maintenance.

[0008] Therefore, there is an urgent need for a new type of roof suitable for substations that integrates efficient prefabrication, rapid assembly, reliable sealing, long-lasting waterproofing and thermal insulation, and good fire resistance, in order to overcome the shortcomings of existing technologies, improve construction efficiency, ensure project quality, and reduce the total life cycle cost. Summary of the Invention

[0009] To address these issues, this invention provides a substation roof assembly and a prefabricated roof, which solves the problems of long construction cycles, low efficiency, and unreliable waterproofing and insulation performance caused by the on-site concrete pouring method used in the prior art for substation roofs.

[0013] Preferably, the top ends of the first connector and the second connector both extend upwards to be flush with the waterproof layer, and the top surface of the waterproof layer, the top surface of the first connector, and the top surface of the second connector together form a flat surface. The panel is covered on the flat surface, and a filling step is formed between the first connector and the limiting block located above. When the plug is used to plug into the corresponding plug slot, the filling step and the second connector step form a filling groove with the slot opening located at the flat surface, and the filling groove is filled with a filling layer.

[0014] Preferably, the mounting position has a slot and a groove, the bottom end of the first connector protrudes downward from the bottom of the insulation layer, the limiting block located below is connected to the bottom end of the first connector and forms a locking block with the bottom end of the first connector, the locking block is engaged in the slot, and the bottom end of the second connector protrudes downward from the bottom of the insulation layer and is inserted into the groove.

[0015] Preferably, the mounting position is further provided with a plurality of mounting slots spaced laterally, and the plurality of mounting slots are disposed between the card slot and the slot. The bottom of the insulation layer is connected to a plurality of mounting blocks, the number of which is the same as the number of mounting slots and they are arranged in a one-to-one correspondence.

[0016] This invention also provides a prefabricated roof for a substation, the prefabricated roof including a roof panel and multiple roof components, the multiple roof components being arranged longitudinally at intervals, each roof component including multiple roof fittings of the substation as described above, arranged sequentially in the transverse direction, each roof fitting being disposed on the top of the roof panel; in any two adjacent roof fittings, the first connecting structure of one roof fitting is connected to the second connecting structure of the other roof fitting, so as to assemble the multiple roof fittings into the roof component.

[0017] Preferably, the bottom of the roof panel is provided with a support structure, the support structure including a plurality of support ribs arranged longitudinally at intervals, the support ribs supporting the bottom of the roof panel.

[0018] Preferably, a fire-resistant foam layer is filled between any two adjacent roof fittings along the longitudinal direction; and / or, a covering strip overlaps between the waterproof layers of any two roof fittings along the longitudinal direction.

[0019] Preferably, the prefabricated roof includes at least one ridge module, the ridge module including a pair of roof components arranged adjacent to each other in the longitudinal direction, and the remaining roof components other than the ridge module are all planar components; each ridge module has planar components on both sides in the longitudinal direction, and the roof fittings in each planar component are all arranged horizontally; in each ridge module, two roof fittings that are adjacent in the longitudinal direction are arranged at an angle, and each ridge module is covered with a ridge trim that matches the top of the ridge module.

Combined with the filling layer at the joints and the longitudinally overlapping covering strips, a continuous and reliable waterproof and insulation barrier is formed. This design not only improves the overall waterproof reliability and insulation continuity of the roof, but also effectively protects the core materials and extends their service life.

[0022] (3) Lightweight and economical, enhancing safety and adaptability: The prefabricated roofing system is much lighter than traditional concrete roofs, reducing the load requirements on the underlying support structure and saving civil engineering costs. At the same time, the system integrates fireproof foam layers, ridge trims and other designs, enhancing the overall fire safety of the roof and its adaptability to different roof shapes (such as flat and ridge roofs), achieving a balance between safety, functionality and economy.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: To address the problems of lengthy construction cycles, low efficiency, and unreliable waterproofing and insulation performance associated with on-site concrete pouring for substation roofs in existing technologies, this invention proposes a substation roof assembly 100, comprising: Base plate 10, on which mounting position 11 is formed; The inner core structure 20 includes a waterproof layer 21 and a thermal insulation layer 22 arranged sequentially from top to bottom, with the thermal insulation layer 22 installed at the mounting position 11. The first connecting structure 30 and the second connecting structure 40 are respectively disposed at both ends of the inner core structure 20 along the transverse direction. The first connecting structure 30 and the second connecting structure 40 are both installed at the mounting position 11. The first connecting structure 30 is used to connect with the second connecting structure 40 of another roofing accessory 100, and the second connecting structure 40 is used to connect with the first connecting structure 30 of yet another roofing accessory 100. Panel 50 covers the top of waterproof layer 21, first connecting structure 30 and second connecting structure 40.

[0027] As can be seen from the above technical solution, the present invention proposes a roof assembly for a substation. First, the base plate 10 is provided with an installation position 11, which serves as the load-bearing foundation for the entire component, ensuring the stable positioning of the structure and the ease of installation. Second, the inner core structure 20 is composed of a waterproof layer 21 and an insulation layer 22 arranged from top to bottom, and is fixed to the installation position 11, realizing the integrated function of roof waterproofing and insulation, effectively improving performance reliability. Third, the first connecting structure 30 and the second connecting structure 40 respectively set at the two ends of the inner core structure 20, through the cooperation of the insertion slot 31 and the insertion block 41, realize the quick and reliable docking and self-locking between adjacent components, significantly improving the on-site assembly efficiency and ensuring the sealing of the joints. Finally, the panel 50 covering the top and the base plate 10 together constitute a rigid outer protective layer, protecting the inner core from external damage, further enhancing the durability of the roof and the overall waterproof effect.

[0028] Please see Figures 1 to 5 In one embodiment of the present invention, the roofing fitting 100 includes a base plate 10, an inner core structure 20, a first connecting structure 30, a second connecting structure 40, and a panel 50; wherein, an installation position 11 is formed on the base plate 10; the inner core structure 20 includes a waterproof layer 21 and an insulation layer 22 arranged sequentially from top to bottom, and the insulation layer 22 is installed at the installation position 11; the first connecting structure 30 and the second connecting structure 40 are respectively disposed at both ends of the inner core structure 20 in the transverse direction, and both the first connecting structure 30 and the second connecting structure 40 are installed at the installation position 11, the first connecting structure 30 is used to connect with the second connecting structure 40 of another roofing fitting 100, and the second connecting structure 40 is used to connect with the first connecting structure 30 of yet another roofing fitting 100; the panel 50 covers the top of the waterproof layer 21, the first connecting structure 30, and the second connecting structure 40.

[0029] In one embodiment of the present invention, the first connecting structure 30 is provided with a plug groove 31, the opening of the plug groove 31 is disposed away from the second connecting structure 40, the second connecting structure 40 is provided with a plug block 41, the plug block 41 protrudes in a direction away from the first connecting structure 30, the plug groove 31 is used to plug into the plug block 41 of another second connecting structure 40, and the plug block 41 is used to plug into the plug groove 31 of yet another first connecting structure 30.

[0030] Horizontal Figure 1 The left and right directions, and the vertical direction are Figure 3 The front and back directions in the middle.

[0031] The technical solution of this invention involves prefabricating roofing components 100 in a factory, transporting the prefabricated roofing components 100 to the site, assembling multiple roofing components 100, connecting the first connecting structure 30 of each roofing component 100 to the second connecting structure 40 of an adjacent roofing assembly machine, and connecting the second connecting structure 40 to the first connecting structure 30 of another adjacent roofing component 100. This completes the assembly of the roofing components 100 and thus the construction of the roof. The method is simple, convenient, has a short construction cycle, and high construction efficiency.

[0032] Furthermore, an installation position 11 is formed in the base plate 10. The installation position 11 is used to support the inner core structure 20, the first connecting structure 30, and the second connecting structure 40. The inner core structure 20 consists of a waterproof layer 21 and an insulation layer 22 arranged sequentially from top to bottom. The insulation layer 22 is installed in the installation position 11, and a panel 50 is placed on top of the waterproof layer 21. The panel 50, waterproof layer 21, insulation layer 22, and base plate 10 arranged sequentially from top to bottom together form a multi-layer structure. In this multi-layer structure, not only does the waterproof layer 21 play a waterproof role, but the panel 50 and base plate 10 also play a waterproof role. Therefore, the roof assembly machine has a good waterproof effect and can meet the roof waterproofing requirements. In addition, the base plate 10 and panel 50 can also provide protection for the inner core structure 20, thereby effectively preventing damage to the inner core structure 20 from external influences and ensuring the reliability of waterproof and insulation performance. Furthermore, the connection between the first connecting structure 30 and the second connecting structure 40 not only connects the two roofing components 100 but also seals them together, ensuring the continuity of waterproofing and insulation between the roofing components 100. Moreover, the prefabricated roof assembled using the roofing components 100 of this invention is lighter in weight than traditional cast-in-place roofs that require a large amount of concrete, effectively reducing the amount of material needed for the roof's lower support structure 202 and resulting in lower costs.

[0033] It should be noted that the installation of the base plate 10, the panel 50, the waterproof layer 21, the insulation layer 22, the first connecting seat 32, and the second connecting seat 42 are all done by adhesive bonding.

[0034] In one embodiment of the present invention, the first connecting structure 30 is provided with a plug groove 31, the opening of the plug groove 31 is disposed away from the second connecting structure 40, the second connecting structure 40 is provided with a plug block 41, the plug block 41 protrudes in a direction away from the first connecting structure 30, the plug groove 31 is used to plug into the plug block 41 of another second connecting structure 40, and the plug block 41 is used to plug into the plug groove 31 of yet another first connecting structure 30.

[0035] Specifically, the interlocking groove 31 and the interlocking block 41 can be horizontally inserted and self-locked, eliminating the need for bolts, welding, and additional fasteners, thus speeding up installation. The groove wall envelops the interlocking block 41, forming a double upper and lower limit, making it difficult for the interlocking block 41 to detach from the interlocking groove 31, resulting in a more reliable connection. Furthermore, the interlocking block 41 and the interlocking groove 31 also have a sealed fit, which can further improve the continuity and reliability of waterproofing and thermal insulation between the two roof fittings 100.

[0036] In one embodiment of the present invention, the first connecting structure 30 includes a first connecting seat 32 and two limiting blocks 33. The first connecting seat 32 is installed at one end of the inner core structure 20 along the lateral direction. The two limiting blocks 33 are connected to one end of the first connecting seat 32 away from the second connecting structure 40, and the two limiting blocks 33 are arranged vertically at intervals. The two limiting blocks 33 and the first connecting seat 32 enclose each other to form a plug-in groove 31. The second connecting structure 40 includes a second connecting seat 42 and a plug-in block 41. The second connecting seat 42 is disposed at the other end of the inner core structure 20 along the lateral direction. The plug-in block 41 is connected to one end of the second connecting seat 42 away from the first connecting structure 30. The two limiting blocks 33 that form the plug-in groove 31 are connected to the corresponding plug-in block 41 through a connector 70.

[0037] Furthermore, the two limiting blocks 33 and the first connecting seat 32 enclose each other to form a plug groove 31. When the plug block 41 is inserted into the plug groove 31, the plug block 41 and the two limiting blocks 33 are connected as one unit by the connector 70, which can improve the vertical shear and tensile strength of the plug block 41 after it is inserted into the plug groove 31. This ensures that the plug block 41 will not come loose from the plug groove 31 under the repeated action of wind suction or temperature, thus guaranteeing the reliability of the connection and the reliability of the seal between the two roof fittings 100.

[0038] In one embodiment of the present invention, the top end of the first connecting seat 32 and the top end of the second connecting seat 42 both extend upward to be flush with the waterproof layer 21, and the top surface of the waterproof layer 21, the top surface of the first connecting seat 32 and the top surface of the second connecting seat 42 form a common flat surface. The panel 50 is covered on the flat surface, and a filling step 60 is formed between the first connecting seat 32 and the upper limiting block 33. When the plug-in block 41 is used to plug into the corresponding plug-in slot 31, the filling step 60 and the second connecting step form a filling groove 61 with the slot located on the flat surface, and the filling groove 61 is filled with a filling layer 62.

[0039] Specifically, the tops of both the first connecting seat 32 and the second connecting seat 42 extend upwards to be flush with the waterproof layer 21, so that the top surface of the waterproof layer 21, the top surface of the first connecting seat 32, and the top surface of the second connecting seat 42 together form a flat surface, on which the panel 50 is covered. A filling step 60 is formed between the first connecting seat 32 and the upper limiting block 33. When the insertion block 41 is inserted into the insertion groove 31, the filling step 60 and the second connecting seat 42 form a filling groove 61 with the groove opening located on the flat surface, and the filling groove 61 is filled with a filling layer 62. This structure allows the panel 50 to fit tightly with the underlying layers, and a continuous and closed filling layer 62 is formed at the top of the splicing joint, preventing rainwater from directly entering the insertion part and enhancing the continuity of waterproofing. At the same time, the filling layer 62 is flush with the flat surface, avoiding water accumulation, reducing the risk of aging, and improving the durability of the roof.

[0040] Furthermore, the filling layer 62 is a polyurethane filling layer 62. The polyurethane fills the filling groove 61 and is firmly bonded to the groove wall to form a continuous and seamless elastomer. It can expand and contract with temperature changes without cracking, and rainwater is completely blocked, resulting in higher waterproof effect and reliability. In addition, the polyurethane filling layer 62 also has a heat insulation function, which can further improve the heat insulation effect between the first connecting seat 32 and the second connecting seat 42.

[0041] In one embodiment of the present invention, a slot 111 and a slot 112 are formed at the mounting position 11. The bottom end of the first connecting seat 32 protrudes downward from the bottom of the insulation layer 22. The limiting block 33 located below is connected to the bottom end of the first connecting seat 32 and forms a locking block 34 with the bottom end of the first connecting seat 32. The locking block 34 is engaged with the slot 111. The bottom end of the second connecting seat 42 protrudes downward from the bottom of the insulation layer 22 and is inserted into the slot 112.

[0042] Specifically, the cooperation between the card block 34 and the card slot 111, and between the bottom end of the second connecting seat 42 and the slot 112, can firmly fix the first connecting seat 32 and the second connecting seat 42 onto the base plate 10, thereby achieving quick positioning and reliable installation through the first connecting seat 32 and the second connecting seat 42, making the structure more reliable.

[0043] In one embodiment of the present invention, a plurality of mounting slots 113 are also formed on the mounting position 11, which are arranged laterally. The plurality of mounting slots 113 are all disposed between the card slot 111 and the slot 112. A plurality of mounting blocks 80 are connected to the bottom of the insulation layer 22. The number of mounting blocks 80 is the same as that of the mounting slots 113 and they are arranged in a one-to-one correspondence. Each mounting block 80 is inserted into its corresponding mounting slot 113.

[0044] Furthermore, by connecting multiple mounting blocks 80 to the bottom of the insulation layer 22 and inserting the multiple mounting blocks 80 into the multiple mounting slots 113 respectively, the relative horizontal displacement between the inner core structure 20 and the base plate 10 can be effectively prevented, so that the inner core structure 20 can be more reliably installed on the base plate 10, and the structure is reliable.

[0045] In one embodiment of the present invention, the waterproof layer 21 is a waterproof layer 21 made of thermoplastic polyolefin polymer waterproof membrane. The base plate 10 and the panel 50 are both metal plates. The waterproof layer 21 made of thermoplastic polyolefin polymer waterproof membrane has good elasticity, high elongation at break, and good weather resistance. It can deform synchronously with the thermal expansion and contraction of the roof without cracking, and also has good puncture resistance. The metal base plate 10 and the panel 50 form a rigid outer shell, effectively preventing external forces from puncturing or abrading the waterproof layer 21, thus extending the waterproof life. The metal plate and the waterproof layer are tightly bonded, blocking the water vapor penetration path and reducing the risk of leakage.

[0046] Example 2: This invention proposes a prefabricated roof for a substation. The prefabricated roof includes a roof panel 201 and multiple roof components 200. The multiple roof components 200 are arranged longitudinally at intervals. Each roof component 200 includes multiple roof fittings 100 of the aforementioned substation, arranged sequentially laterally. Each roof fitting 100 is disposed on top of the roof panel 201. For any two adjacent roof fittings 100, a first connecting structure 30 of one roof fitting 100 is connected to a second connecting structure 40 of the other roof fitting 100, so that the multiple roof fittings 100 are assembled into a roof component 200. The specific structure of the roof fittings 100 of this substation is as described in the above embodiment. Since the prefabricated roof of this substation adopts all the technical solutions of Example 1, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0047] Specifically, positioning lines are first laid out on the roof panel 201 at longitudinal intervals. Then, the first piece of the same roof component 200 is hoisted onto the top of the roof panel 201, leveled, and temporarily fixed. Next, the first connecting structure 30 of the adjacent roof component 100 is horizontally inserted into the second connecting structure 40 of the already positioned component, pushed tight, and automatically locked. The horizontal assembly of the component is completed in sequence. By setting up multiple roof components 200 at longitudinal intervals in the same manner, a continuous prefabricated roof can be formed on the top of the roof panel 201.

[0048] In one embodiment of the present invention, a support structure 202 is provided at the bottom of the roof panel 201. The support structure 202 includes a plurality of support ribs 2021 arranged longitudinally at intervals, and the support ribs 2021 are supported at the bottom of the roof panel 201.

[0049] Specifically, support ribs 2021 are arranged longitudinally at intervals at the bottom of the roof panel 201. The top of the ribs is fixed to the bottom surface of the roof panel 201 to form a grid-like bottom support. Cavities are left between adjacent ribs, and the bottom of the ribs is supported by the roof. The load of the prefabricated roof can be evenly distributed to the roof through the support ribs 2021.

[0050] In one embodiment of the present invention, a fireproof foam layer 203 is filled between two longitudinally adjacent roof components 200 and between two longitudinally adjacent roof fittings 100; and / or, a covering strip 204 overlaps between the waterproof layers 21 of any two longitudinally adjacent roof fittings 100.

[0051] Specifically, the fireproof foam layer 203 fills the gaps between the longitudinally adjacent roof fittings 100, forming a continuous flame-retardant strip that can slow the spread of flames along the seams and improve the overall fire resistance of the roof. The covering strip 204 overlaps on the waterproof layers 21 on both sides, completely covering the longitudinal joints, blocking the path of rainwater penetration, and preventing the foam layer from failing when exposed to water. The overlapping and filling are completed simultaneously, making the construction simple. It ensures both waterproof continuity and fire safety. Later maintenance only requires checking the integrity of the covering strip 204, reducing operation and maintenance costs.

[0052] In one embodiment of the present invention, the prefabricated roof includes at least one ridge module 205, the ridge module 205 includes a pair of roof components 200 arranged adjacent to each other in the longitudinal direction, and the other roof components 200 besides the ridge module 205 are all planar components 207; each ridge module 205 has planar components 207 arranged on both sides in the longitudinal direction, and the roof fittings 100 in each planar component 207 are all arranged horizontally; in each ridge module 205, two roof fittings 100 that are adjacent in the longitudinal direction are arranged at an angle, and each ridge module 205 is covered with a ridge trim 206 that matches the top of the ridge module 205.

[0053] Specifically, at the ridge, a pair of longitudinally adjacent roof components 200 are first adjusted and fixed according to the ridge angle, so that the corresponding roof fittings 100 form an angled slope, constituting the ridge module 205; the remaining areas are maintained with the roof fittings 100 laid horizontally, forming a flat component 207. Then, a ridge trim 206 matching the angle is fastened onto the top of the ridge module 205, with the two flanges of the ridge trim 206 respectively covering the roof fittings 100 on the corresponding slope and secured with self-rivets, completing the ridge closure. The tight fastening between the ridge trim 206 and the roof fittings 100 effectively prevents rainwater infiltration, improving the waterproofing reliability at the ridge.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
