Description

Technical Field

[0001] The present invention relates to the technical field of roofing construction, and particularly to an assembled sliding and splicing roof. Background Art

[0002] In recent years, metal roof structures have been widely used in large-span building structures such as railway stations, airports, and scientific research factories due to their advantages of light weight, good heat preservation effect, and fast construction speed. Generally, in large-scale steel structure roof projects, in order to reduce the lap of roof panels, increase the integrity of the roof, ensure the waterproof ability of the roof and the overall compressive ability, and the profiled metal roof panel has the advantages of light self-weight, beautiful appearance, and convenient and fast construction, large-span metal roof panels are widely used. However, there are also many problems in the existing technologies.

[0003] In terms of construction quality, since the connections are prone to being loosely connected and deformed during the overall installation of metal roof panels, and the connection methods between the components of the roof panels usually adopt mechanical connections such as locking, biting, or clamping forms, the connection stiffness is low. When subjected to strong wind loads or ordinary wind loads with specific wind vibration frequencies, wind uplift accidents occur. For example, in the existing patent document with the publication number CN218176365U and the patent name of a metal roof panel reinforcement and fastening structure, it specifically discloses that "it includes a ridge cover and a ridge connecting piece, and an elastic traction device for pulling the two side plates of the ridge cover towards the center is installed inside the ridge cover; the ridge cover of the present invention is pulled by the elastic traction device inside it, so that the two side plates of the ridge cover are pulled inwards, and in cooperation with the buckles on the ridge cover, the connection strength between the ridge cover and the ridge connecting piece can be increased, and the risk of the ridge cover being blown off by strong winds can be reduced", although the above technology can increase the wind uplift resistance of metal roof panels to a certain extent, it often adopts a multi-point layout form, with a dense layout and each point acting independently, and the fixing points cannot cooperate to bear force, resulting in low stability and possible detachment in extreme cases.

[0004] In terms of construction safety, since steel structures require high-altitude operations, their construction workers often have safety hazards during high-altitude operations, and precision control during the construction process is also a difficult point, and it is impossible to achieve efficient and economical utilization of the roof system. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to solve the problems of poor construction precision and construction safety existing in current metal roofs.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0017] As a further solution of the present invention: the side edge of the upper roof panel is adapted to the shape of the limiting vertical rod, and its top is also an arc-shaped protrusion, and concave sections and convex sections are successively arranged downward along both sides of the arc-shaped protrusion, and the multi-section structure is integrally formed with the upper roof panel.

[0018] As a further solution of the present invention: the reinforcement assembly includes a fastening beam, a sliding rod and a slider, wherein two groups of fastening beams are provided and are parallelly distributed on the lower roof panel, and a plurality of sliders are installed on each group of fastening beams; both ends of the sliding rod are detachably connected to the sliders on the two groups of fastening beams.

[0019] As a further solution of the present invention: the distance between the two groups of fastening beams is controlled by a first adjusting structure, and the distance between the two groups of sliding rods is controlled by a second adjusting structure.

[0020] As a further solution of the present invention: the first adjusting structure includes serrated slide bars opened on the side walls at both ends of the sliding rod; a groove is opened at the top of the slider, and the groove is just slidably connected to the sliding rod, and serrated pin holes are opened on both the front and rear sides of the slider, and the serrated pin holes and the serrated slide bars are locked by serrated pins.

[0021] As a further solution of the present invention: the second adjusting structure includes a plurality of groups of positioning pin holes opened at equal intervals on both sides of the fastening beam; a steel groove is opened at the bottom of the slider, and the steel groove is slidably connected to the fastening beam, and butterfly pin holes are also opened on both the left and right sides of the slider, and the butterfly pin holes and the positioning pin holes on the fastening beam are locked by butterfly pins.

[0026] As a further solution of the present invention: a connecting bridge is also snap-fitted on the top of the connecting plate and the upper roof panel, and a thermal insulation and vapor barrier component is also laid on the top of the lower roof panel and below the upper roof panel.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] First, the present invention assembles several sets of roof modules into a whole roof. The reinforcing component and the self-locking component are used to fix the roof template, and the connecting plate and the waterproof strengthening component are used to fix the two adjacent roof modules during splicing, thereby ensuring the stability of the roof template and the whole roof. Multiple reinforcement points work together with high utilization rate, ensuring the stability and load-bearing capacity of the whole roof. At the same time, the method of prefabricating individual modules and then splicing them is flexible in operation, convenient for installation, can also speed up the construction progress, and ensure the safety of construction workers. The setting of the self-locking component can solve the weakness of the roof system in terms of wind uplift resistance, as well as problems such as poor installation accuracy and construction safety, enabling the overall metal roof system to ensure wind resistance quality under the coordinated action of the support and various reinforcement components.

[0029] Second, the upper cross-section of the fixed support of the present invention is larger than the lower cross-section, presenting an upper-wide and lower-narrow structure, and the standing seam edge (i.e., the side edge) of the roof panel is also an upper-wide and lower-narrow structure. The two cooperate with each other to effectively resist the negative pressure effect caused by wind load (i.e., resist the uplift force). At the same time, an inclined triangular gusset plate is arranged at the lower small cross-section part of the fixed support to effectively ensure the compressive effect of the support. Before the lower roof panel is damaged, it can reinforce the lower roof panel, thereby solving the weakness of the roof panel in terms of wind uplift resistance in its inherent form, as well as problems such as poor installation accuracy and construction safety, enabling the overall metal roof system to ensure wind resistance quality under the coordinated action of the support and various reinforcement components, and greatly improving the structural strength, stiffness and wind resistance performance of the roof panel.

[0030] III. The present invention locks the two sides of adjacent lower roof panels by setting a self-locking component. The outer clamping member can wrap the inner clamping member from the outside, and the protrusion of the inner clamping member engages with the outer clamping member, thereby ensuring the self-locking between the inner clamping member and the outer clamping member. At the same time, fixed supports are provided on the inner sides of the inner and outer clamping members. The fixed supports can jack up and support the bottoms of the two sides of the lower roof panel, while the inner and outer clamping members lock the lower roof panel from the outside, ensuring the stability of the lower roof panel during installation and improving the wind resistance of the lower roof panel;

[0031] IV. A number of groups of positioning pin holes are equidistantly arranged on both sides of the fastening beam. The slider can slide on the fastening beam, and at the same time, butterfly pin holes corresponding to the positioning pin holes are arranged on the slider. Therefore, the fastening beam and the slider can be fixed through the butterfly pin. The staff can move and adjust the slider by controlling the installation of the butterfly pin, and the relative movement of the upper roof panel above the fastening beam can be realized. Furthermore, the connection between adjacent roof panels can be realized, which has high flexibility, strong practicability, and is easy to install, and can greatly accelerate the construction speed;

[0032] V. The top of the slider of the present invention can be slidably connected to the sliding rod. A serrated pin hole is arranged on the slider, and a corresponding serrated slide bar is arranged on the sliding rod. Then the serrated pin passes through the serrated pin hole and can be engaged into the serrated slide bar, thereby realizing the locking between the slider and the sliding rod. At the same time, the fine adjustment of the sliding rod can be realized, avoiding the problem of locking between the slider and the sliding rod, and facilitating the adjustment of the position, that is, adjusting the distance between the two fastening beams for different lower roof panels to make it applicable to different sizes of lower roof panels, ensuring the efficient connection of subsequent roof panels, with high flexibility, strong practicability, and easy to install, and can greatly accelerate the construction speed;

[0033] VI. The present invention places a thermal insulation and vapor barrier component at the gaps between the fastening beam and the sliding rod. The thermal insulation and vapor barrier component includes a vapor barrier layer, a thermal insulation layer, and a waterproof layer from top to bottom. The fastening beam, the sliding rod, and the fixed support can support the upper roof panel, so that the thermal insulation and vapor barrier component is not directly compressed, ensuring the stability of the structure. When subjected to external pressure, the pressure is mainly borne by the support and the reinforcement component, improving the integrity;

[0034] VII. In response to the national development strategy of "dual carbon goals", the present invention uses the technology of photovoltaics, energy storage, direct current, and flexibility. On the premise of meeting national technical standards, the solar panels are fixed on the top of the self-locking fixture by using the nesting method to achieve "energy storage" and "power supply", making the building's electricity demand change from rigid to flexible.

Detailed implementation manners

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] Referring to Figure 1 , Figure 2 and Figure 3 , the prefabricated sliding and assembled roof, the roof of the present application can be a metal roof, etc. There is no limitation on what kind of material here, and it can be determined according to the actual installation situation on site; it is assembled by several groups of roof modules 1. Figure 1 What is given is the figure after the complete assembly of three groups of roof modules 1, while Figure 2 is a partial disassembly diagram after the assembly of three groups of roof modules 1, which is convenient for observation. Figure 3 is a partial disassembly diagram after the assembly of the arc roof; it should be noted that the roof has a flat roof or an arc roof (as shown in Figure 2 ) or a combination of both (that is, a roof with an arc surface at the top and flat surfaces on both sides). Therefore, several groups of roof modules 1 can be assembled into a flat roof, an arc roof, or a combination of both. Specifically, how many groups of roof modules 1 need to be set depends on the actual size of the roof; during the assembly process, adjacent two groups of roof modules 1 are spliced through a connecting plate 2, and a bridge-shaped reinforcement 3 is clamped above the connecting plate 2. It should be noted that multiple bridge-shaped reinforcements 3 can be provided on the connecting plate 2 in the present application, which is determined according to different uplift forces and the on-site construction environment. Specifically, how many are provided is not limited here in the present application.

[0050] Referring to Figure 4 and Figure 5 , the roof module 1 includes a support beam 11, a lower roof panel 12, a reinforcement assembly 13, an upper roof panel 14, a thermal insulation and vapor barrier assembly 15, a mounting bracket 16, a solar panel 17, and a self-locking assembly 18. Among them, the support beam 11 is located at the bottom and is provided at the bottom of the lower roof panel 12. Two to three support beams 11 can be laid along the span direction of the lower roof panel 12, and they can be connected to the lower roof panel 12 by bolts or welding to ensure their stability; the reinforcement assembly 13 is installed on the top of the lower roof panel 12, and the thermal insulation and vapor barrier assembly 15 is located between the reinforcement assemblies 13, which can play a role in thermal insulation and waterproofing for the lower roof panel 12; and the upper roof panel 14 is locked above the reinforcement assembly 13 through the self-locking assembly 18, where the upper roof panel 14 is located on the top of the thermal insulation and vapor barrier assembly 15; two groups of parallelly distributed mounting brackets 16 are installed on the top of the self-locking assembly 18, and a solar panel 17 is installed on the top of the two groups of mounting brackets 16.

[0051] It should be noted that the thermal insulation and vapor barrier assembly 15 from bottom to top is successively a vapor barrier layer, a thermal insulation layer and a waterproof layer, providing vapor barrier, thermal insulation and waterproof effects for the lower roof panel 12. (The thermal insulation and vapor barrier assembly 4 has the same structure as the waterproof reinforcement assembly 15, which is successively a vapor barrier layer, a thermal insulation layer and a waterproof layer from bottom to top); at the same time, the lower roof panel 12 is made of color steel plate, and the upper roof panel 14 is made of aluminum-magnesium-manganese plate, which is the best choice.

[0052] It should be noted that when assembling two adjacent sets of roof modules 1, there are two installation methods. One is the splicing of two adjacent sets of roof modules 1 along the roof span direction, and the other is the splicing of two adjacent sets of roof modules 1 along the direction perpendicular to the roof span (as Figure 1 and Figure 2 shown). The connecting plate 2 has the same structure as the lower roof panel 12, and both ends of the two are provided with edges and are in a corrugated shape in the middle;

[0053] When two adjacent sets of roof modules 1 are spliced along the roof span direction, the two lower roof panels 12 below are overlapped up and down, that is, one lower roof panel 12 is placed on top of the other lower roof panel 12. Such a method helps with waterproofing and water drainage; a waterproof reinforcement assembly 4 is laid between the two middle reinforcement assemblies 13, and the two upper roof panels 14 above are connected by a connecting plate 2. During installation, the two ends of the connecting plate 2 just overlap on two adjacent upper roof panels 14, that is, stacked above the upper roof panel 14. The edges at both ends of the connecting plate 2 are also overlapped up and down, and the overlapping parts at both ends of the two (i.e., the side edges) are fixed by a self-locking assembly 18, so as to realize the splicing of the connecting plate 2 and the two sets of roof modules 1. The upper part of the overlapping part of the upper roof panel 14 and the connecting plate 2 is fixed by a bridge-shaped reinforcement member 3. The middle of the bridge-shaped reinforcement member 3 is in an arc shape and is bent downward in the middle, and both ends are buckled to the upper roof panel 14 or the connecting plate 2, providing a squeezing force for the upper roof panel 14 and the connecting plate 2 so that they can better withstand the wind uplift. It should be noted that multiple bridge-shaped reinforcement members 3 can be provided on the upper roof panel 14 in this application, depending on the different uplift forces and the on-site construction environment. The specific number of them is not limited in this application; before installing the connecting plate 2, a waterproof reinforcement assembly 4 needs to be laid at the bottom of the connecting plate 2 and above the lower roof panel 12 to improve the waterproof performance between the two sets of roof modules 1;

[0054] When two adjacent sets of roof modules 1 are spliced along the direction perpendicular to the roof span, the two lower roof panels 12 below are also overlapped up and down (the same as the splicing method along the roof span direction above), the two middle reinforcement assemblies 13 are connected to ensure that the reinforcement assemblies 13 of the entire roof are finally connected into one body, and the two adjacent upper roof panels 14 above are also stacked up and down, and then both overlapping parts are fixed by a self-locking assembly 18.

[0055] Reference Figure 6 , the reinforcement component 13 includes a fastening beam 131, a sliding rod 132 and a slider 133. The fastening beam 131, the sliding rod 132 and the slider 133 form a frame-like structure and are located at the middle position on the top of the lower roof panel 12. Among them, two groups of fastening beams 131 are provided and are laid parallel on the lower roof panel 12. A number of sliders 133 are installed on each group of fastening beams 131, and the sliders 133 can slide back and forth on the fastening beam 131. At the same time, the fastening beam 131 can be selected as an I-beam, which can also realize the up and down limit of the slider 133 and the fastening beam 131. This process can be adjusted accordingly according to the needs of the staff. And a number of groups of sliding rods 132 are also provided, and both ends of each sliding rod 132 are detachably connected to the sliders 133 on the two groups of fastening beams 131. After installation, the sliding rod 132 is vertically distributed with the fastening beam 131, and the several groups of sliding rods 132 are parallel to each other. It should be noted that the specific number of groups of sliders 133 provided on each group of fastening beams 131 depends on the on-site installation situation; similarly, the specific number of groups of sliding rods 132 also depends on the on-site installation situation.

[0056] Furthermore, referring to Figure 6 and Figure 7 , a number of groups of positioning pin holes are equidistantly opened on both sides of the fastening beam 131, and a steel groove 1333 is opened at the bottom of the slider 133. Among them, the steel groove 1333 is just slidably connected to the fastening beam 131. Butterfly pin holes 1331 are also opened on the left and right sides of the slider 133. The butterfly pin holes 1331 are structures with wide ends and narrow middle, and this shape has good stability; among them, the butterfly pin holes 1331 and the positioning pin holes on the fastening beam 131 are locked by butterfly pins 1332. During the assembly process, when the staff needs to adjust the distance between two adjacent sliding rods 132, the distance between the two sliders 133 on the fastening beam 131 can be adjusted, that is, the slider 133 is slid on the fastening beam 131 for adjustment. After adjusting to the required position, use the butterfly pin 1332 to lock the slider 133 and the fastening beam 131;

[0057] It should be noted that the side cross-section of the fastening beam 131 is in an I-shaped structure, and fastening grooves are opened at both ends of the fastening beam 131, and the fastening grooves are half grooves for the butterfly pin 1332. When two fastening beams 131 are spliced, the ends of the two fastening beams 131 both extend into the slider 133, and then the butterfly pin 1332 is inserted into the butterfly pin holes formed by the fastening grooves on the two fastening beams 131, and the fixation of the two fastening beams 131 can be realized (as Figure 6It can be seen that there is a fastening groove at the end of the fastening beam 131), so as to complete the connection and fixation between two adjacent fastening beams 131. Adopting this structure can greatly increase the stability between two adjacent fastening beams 131, further realize the connection between adjacent roof panels, with high flexibility, strong practicability, and simple installation, which can greatly accelerate the construction speed.

[0058] Furthermore, referring to Figure 6 and Figure 7 , serrated slide bars 1321 are provided on the side walls at both ends of the sliding rod 132; a groove 1336 is formed at the top of the slider 133, and the groove 1336 is exactly slidably connected to the sliding rod 132. Serrated pin holes 1335 are formed on both the front and rear sides of the slider 133. The serrated pin holes 1335 and the serrated slide bars 1321 are locked by serrated pins 1334. During the assembly process, when the staff needs to adjust the distance between two adjacent sliders 133, the length of the sliding rod 132 between the fastening beams 131 can be adjusted, that is, the sliding rod 132 is slid within the slider 133 for adjustment. After adjusting to the required position, the slider 133 and the sliding rod 132 are locked with the serrated pin 1334.

[0059] Referring to Figure 8 and Figure 9 , the self-locking assembly 18 includes an outer clamping member 181 and an inner clamping member 182. The outer clamping member 181 includes an inner clamping groove, and the inner clamping member 182 includes a clamping key adapted to the inner clamping groove. The clamping key is inserted and cooperated with the inner clamping groove to enclose a support clamping groove. The top protrusion of the outer clamping member 181 wraps the inner clamping member 182 from above to achieve double clamping and self-locking, that is, the outer clamping member 181 and the inner clamping member 182 are not only clamped inside by the inner clamping groove and the clamping key, but also the inner clamping member 182 is wrapped by the outer clamping member 181 outside, so as to realize the double self-locking of the self-locking assembly 18 and ensure the stability of the self-locking assembly 18; clamping grooves are formed on the inner sides of both the outer clamping member 181 and the inner clamping member 182. A fixed support 183 is clamped in the support clamping groove formed by the two groups of clamping grooves, that is, the outer contour of the fixed support 183 is adapted to the support clamping groove. The two side edges of the upper roof panel 14 are limited between the support clamping groove and the fixed support 183. It should be noted that the support clamping groove is composed of upper and lower parts. The upper part is a fan-shaped groove, and the lower part is a rectangular groove (as Figure 9 shown).

[0060] Further, when the self-locking assembly 18 and the fixed support 183 lock the upper roof panel 4 and the connecting plate 2, the ends of the upper roof panel 14 and the connecting plate 2 can wrap around the outside of the fixed support 183. At this time, the fixed support 183 supports the upper roof panel 14 and the connecting plate 2 from the inside, and then the outer clamping member 181 and the inner clamping member 182 fix the upper roof panel 14, the connecting plate 2 and the fixed support 183 from both sides, that is, the outer clamping member 181 and the inner clamping member 182 fix the upper roof panel 14 and the connecting plate 2 from the outside. It should be noted here that two layers of connecting plates 2 or adjacent roof panels can be stacked on the top of the upper roof panel 14, and then locked by the self-locking assembly 18. This situation can be seen when two adjacent roof modules are spliced. From Figure 1 it can be seen.

[0061] Refer to Figure 10 , the fixed support 183 includes a positioning cross plate 1832 and a limiting vertical rod 1831 vertically arranged on the positioning cross plate 1832. The limiting vertical rod 1831 has an upper-wide and lower-narrow structure, and the inclined triangular gusset plates on both sides of its bottom are fixed to the positioning cross plate 1832. The top of the limiting vertical rod 1831 is an arc-shaped protrusion, and an inner concave section and a protrusion section are sequentially arranged downward along both sides of the arc-shaped protrusion. And this multi-section structure is integrally formed with the limiting vertical rod 1831.

[0062] Figure 11 Another implementation manner of the fixed support 183 is shown, which also adopts an upper-wide and lower-narrow structure, but there are some differences at the top, and it can also be applied to the overall roof of the present invention.

[0063] As Figure 8 shown, the side edge of the upper roof panel 14 is adapted to the shape of the limiting vertical rod 1831. Its top is also an arc-shaped protrusion, and an inner concave section and a protrusion section are sequentially arranged downward along both sides of the arc-shaped protrusion. And this multi-section structure is integrally formed with the upper roof panel 14.

[0064] Refer to Figure 12 , both sides of the solar panel 17 are embedded and installed in the nested plate 19. There are two sets of nested plates 19, which are respectively detachably installed above the two sets of mounting brackets 16. It should be noted that the outside of the nested plate 19 is also fixed to the opening on the mounting bracket 16 by bolts through an L-shaped connecting plate, which increases the stability of the nested plate 19. Using the optical storage direct current and flexible technology, on the premise of meeting the national technical standards, the solar panels are fixed on the top of the self-locking assembly 18 by the nesting method to achieve "energy storage" and "power supply", so that the building's electricity demand changes from rigid to flexible.

[0065] The installation method of the prefabricated sliding and assembling roof of the present application:

[0066] Before assembly, ① Firstly, before assembling the metal roof, an assembly platform needs to be set up on the ground in the span direction of the factory building. The height of the assembly platform needs to reach the height of the roof columns and meet the load requirements, and temporary assembly rails need to be set on the roof columns and beams of the factory building; ② The steel structure factory building needs to be partitioned and assembled in sections. For a larger structural span, multiple roof panels need to be fixed on the assembly platform and then installed by integral sliding; ③ Bolt holes need to be set on the roof columns and beams so that the roof modules can slide to the designated positions for bolt fixing.

[0067] It should be noted that the bottom of the assembly platform is supported by several support columns, and the top of the platform can be slightly lower than the height of the roof columns. When installing, the workers transport the components to the platform and then directly assemble them above the assembly platform, which is convenient for placing the modules on the roof columns as a whole.

[0068] The method for assembling a single roof module in this application:

[0069] During assembly, ① Transport the prefabricated parts of the factory roof module 1 to the site and assemble a single roof module 1 on the assembly platform; ② Then install the lower roof panel 12 above the support beam 11, and install sliding shoes at the bottom of the support beam 11. The sliding shoes can slide on the rails. Sequentially lay the fastening beam 131, slider 133 and sliding rod 132 above the lower roof panel 12 and lock the three of them. Subsequently, install the self-locking component 18 above the sliding rod 132 and use the self-locking component 18 to fix the upper roof panel 14; Place the thermal insulation and air barrier layer 15 at the gaps between the fastening beam 131 and the sliding rod 132. The thermal insulation and air barrier layer 15 consists of a vapor barrier layer, a thermal insulation layer and a waterproof layer from bottom to top. Finally, install the solar panel 17 above the self-locking component 18;

[0070] ③ Slide the assembled single roof module 1 to the designated position on the roof using the rails on the roof columns. Subsequently, use a jack to lift the roof module. The jack lifts the upper support beam 11 of the module and slowly places the whole module on the roof columns, and then fix it as a whole. Remove the sliding shoes and the corresponding segmented rails, and then fix the connection between the roof module 1 and the roof columns; It should be noted here that if the span between the roof columns is very large, temporary steel columns can be set in the middle of the span direction. The temporary steel columns have the same height as the left and right roof columns, and rails are also placed on the temporary columns. The sliding steps are the same as before. After both sides of the unit roof slide to the designated positions at the same time, then bolt the bottom support beams 11 on both sides, and use a jack to remove some of the rails;

[0071] ④Subsequently, a waterproof reinforcement component 4 is laid at the connection of two adjacent roof modules 1, and the two roof modules 1 are connected by a connecting plate 2 above the waterproof reinforcement component 4. During assembly, pay attention to the arrangement of dimensions and the staggered lap joint of the front and rear roof panels. If the span of the factory building is too large, multiple modules are installed and then integrally slid and installed. At the same time, the load stability of the assembly platform needs to be checked. When the span of the factory building is too large, the use of temporary steel columns described in step ④ is used for assistance, and the steps refer to the description of the temporary steel columns above;

[0072] ⑤Perform the above steps in sequence to assemble the overall roof in blocks and slide it to the designated position. Through the fine-tuning system between the fastening beam 131, sliding rod 132 and slider 133 within the roof system itself, the fine-tuning of the roof is carried out to achieve the overall roof effect.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
