Description

Technical Field

[0001] The present invention relates to the technical field of roofing, and particularly relates to a roofing system. Background Art

[0002] In recent years, roofing 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 roofing projects, in order to reduce the lap joints of roof panels, increase the integrity of the roof, ensure the waterproof ability and overall compressive ability of the roof, 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 the construction quality of the roof, since the joints are prone to loose connection and deformation during the overall installation of the roof panels, and the connection methods between the components of the roof panels usually adopt mechanical connections such as snap locks, bites, or clamps, 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 reinforcing snap-fastening structure for metal roof panels, 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; through the traction of the elastic traction device inside the ridge cover, the two side plates of the ridge cover are pulled inwards, and in cooperation with the snap fasteners 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. The fixing points cannot cooperate to bear force, the stability is low, and they may fall off in extreme cases; at the same time, in terms of the safety and convenience of roof construction, the current roof panels are generally installed at high altitudes to complete the overall laying at high altitudes on the roof. However, construction workers often have safety hazards during high-altitude operations, the safety is poor, and during high-altitude construction, the precision control during the construction process is also a difficult point.

[0004] As a key part of the roof, the wind resistance and waterproofing functions of the skylight are of utmost importance. The distribution of the surface wind pressure characteristics of the roof is mainly affected by the self-structural characteristic turbulence. The air flow separates at the highest point of the roof, and the negative pressure is relatively large. Relevant simulations are carried out on the wind pressure distribution of the roof in different directions. At the same time, the current "Code for Loads on Building Structures" (GB 50009-2012) also shows that the negative pressure is relatively large at the highest point of the roof. Compared with the skylights on flat roofs and inclined roofs, the stress state of the skylight at the ridge is complex, and it is extremely easy to cause poor stability of the skylight at this place due to the negative wind pressure effect, making it difficult to resist the influence of strong wind loads and resulting in problems such as deformation and leakage.

[0005] At present, there is generally no corresponding wind resistance and pressure relief treatment for the wind pressure borne by the roof on the market. Most of them are to add reinforcement structures on the ridge. For example, in the existing patent document with the publication number CN214169604U and the patent name of a metal roof wind and snow resistant ridge structure, it specifically discloses that "ridge plugs are respectively fixed on the upper metal profiled sheets of two opposite roofs; the shape of the ridge plugs matches the valley shape of the upper metal profiled sheets of the roof, and the ridge plugs are connected to the peak of the upper surface of the upper metal profiled sheets of the roof; the ridge plugs are connected and fixed to the valley of the upper surface of the upper metal profiled sheets of the roof, and butyl tapes with opposite ends are arranged at the joints, and there is a gap between the two butyl tapes. By using the ridge plugs with special shapes, metal outer ridge tiles, special laying methods of butyl tapes and unique connection methods, the ridge structure of the entire metal roof is made more firm, and the problems of slight air leakage and snow leakage can be effectively solved", but when facing violent storms and snowstorms, it is difficult to resist the deformation of the skylight at the ridge caused by the action of wind load. Summary of the Invention

At the same time, the method of prefabricating modules separately and then splicing them is flexible to operate and convenient to install, and can also speed up the construction progress and ensure the safety of construction workers. The setting of the self-locking component can solve the weak performance, installation accuracy and construction safety of the roof panel in the inherent form of wind-resistant lifting problem, so that the overall roof system can ensure wind-resistant quality under the coordinated action of the support and various reinforcement parts.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. In the present invention, a plurality of groups of roof modules are assembled into a roof body. The connecting plate and the self-locking assembly are used to fix the adjacent two roof modules during assembly, thereby ensuring the stability of the metal roof formwork and the whole roof. Multiple reinforcement points work together with high utilization rate, ensuring the stability and bearing capacity of the whole roof. At the same time, the method of prefabricating the modules separately and then splicing is flexible in operation, convenient for installation, and can also speed up the construction progress, ensuring the safety of construction workers. The setting of the self-locking assembly can solve the weak performance, installation accuracy and construction safety of the roof panel in the anti-wind uplift problem in the inherent form, so that the whole roof system can ensure the anti-wind quality under the coordinated action of the supports and various reinforcement parts. At the same time, a pressure relief and adjustment device is arranged on the skylight. The pressure relief and adjustment device can effectively cope with the deformation problem at the ridge caused by excessive bearing capacity due to strong wind loads. When the negative wind pressure generated exceeds the set pressure, the pressure relief and adjustment device is used to relieve the pressure, ensuring that the roof skylight has good bearing performance.

[0035] 2. 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 self-locking between the inner and outer clamping members. At the same time, fixed supports are provided inside the inner and outer clamping members, and the fixed supports can jack up and support the bottoms of both 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 its wind resistance. The upper cross-section of the fixed support is larger than the lower cross-section, presenting a structure with a wider top and a narrower bottom, and the side edge of the roof panel also has the same structure with a wider top and a narrower bottom. The two cooperate with each other to effectively resist the negative pressure effect caused by wind loads (i.e., resist the uplift force). At the same time, an inclined triangular gusset plate is provided at the small cross-section part of the lower 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, thus solving the weakness of the roof panel in resisting wind uplift in its inherent form, as well as problems such as poor installation accuracy and construction safety. The overall metal roof system ensures the wind resistance quality under the synergistic action of the support and various reinforcement components, greatly improving the structural strength, stiffness and wind resistance performance of the roof panel;

[0036] 3. A number of groups of positioning pin holes are equidistantly arranged on both sides of the fastening beam, and the slider can slide on the fastening beam. At the same time, butterfly pin holes corresponding to the positioning pin holes are provided on the slider. Therefore, the fastening beam and the slider can be fixed through the butterfly pin. Workers can move and adjust the slider by controlling the installation of the butterfly pin, realizing the relative movement of the upper roof panel above the fastening beam, and then realizing the connection between adjacent roof panels. It has high flexibility, strong practicability, and simple installation, which can greatly speed up the construction speed;

[0037] 4. The top of the slider of the present invention can be slidably connected to the sliding rod. A serrated pin hole is provided on the slider, and a corresponding serrated slide bar is provided on the sliding rod. Then the serrated pin passes through the serrated pin hole and can be clamped into the serrated slide bar, thereby realizing the locking between the slider and the sliding rod. At the same time, fine adjustment of the sliding rod can also be realized, avoiding the problem of locking between the slider and the sliding rod, facilitating position adjustment, that is, adjusting the distance between the two fastening beams according to different lower roof panels so that it can be applicable to different sizes of lower roof panels, ensuring the efficient connection of subsequent roof panels. It has high flexibility, strong practicability, and simple installation, which can greatly speed up the construction speed;

[0038] 5. 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 pressed, ensuring the stability of the structure. When subjected to external pressure, the pressure is mainly borne by the support and the reinforcement components, improving the integrity;

[0039] 6. In this application, a slidable sleeve pressure relief component is provided at the four corner positions of the skylight. The sleeve pressure relief component can effectively address the deformation problem at the ridge caused by excessive bearing capacity due to strong wind loads. At the same time, pressure relief holes are provided on the outer sleeve, an elastic member is introduced, and it is combined with a pressure sensor. When the negative wind pressure generated exceeds the pressure set by the pressure relief device, the pressure relief adjustment device opens for pressure relief. After the pressure relief is completed, the elastic member generates a pulling-back effect to timely close the pressure relief adjustment device; when the negative wind pressure generated is lower than the pressure set by the pressure relief device, the skylight may have been damaged. At this time, the elastic member pops up the pressure relief device and opens the pressure relief adjustment device for pressure relief, ensuring that the skylight at the ridge has good load-bearing performance;

[0040] 7. In this application, the splicing at the four sides of the skylight and the roof is integrally spliced with horizontal corrugated plates. The setting of the horizontal corrugated plates greatly increases the contact area at the splicing, making the contact more reliable. At the same time, the horizontal corrugations extend the water seepage path at the joint between the skylight and the roof, and can timely discharge the turbulent water under heavy rain and snow weather, effectively improving the waterproof performance at the joint between the lower opening of the skylight and the metal roof panel;

[0041] 8. In this invention, a C-shaped anti-seepage plate is provided at the junction of the skylight and the upper slope of the pitched roof. In cooperation with the flashing, the prone-to-leakage point is moved upward, effectively solving the leakage phenomenon caused by the accumulation of rainwater at the joint between the skylight and the upper slope of the roof under heavy rain and snow weather conditions. An S-shaped anti-seepage splicing plate is arranged between the C-shaped anti-seepage plate and the roof. The setting of the S-shaped anti-seepage splicing plate ensures a smooth transition at the connection, reduces the connection misalignment caused by stress concentration, and uses rivets to connect at the joints of the C-shaped anti-seepage plate, S-shaped anti-seepage splicing plate and the roof, and seals them with sealant, reducing the contact area at the connection between the C-shaped anti-seepage plate and the roof, making the connection more reliable;

[0042] 9. In this invention, an eaves snow melting and ice thawing component is provided at the upper eaves of the gutter, and a gutter snow melting and ice thawing component is also provided inside the gutter. The solar panel can provide electrical energy for the two snow melting and ice thawing components to achieve snow melting and ice thawing on the upper eaves and inside the gutter of the gutter. At the same time, a siphonic rainwater hopper is provided at the rainwater outlet in the gutter. A rainwater pipe heating tape is provided inside the siphonic rainwater hopper, and a gasket is installed on the siphonic rainwater hopper to avoid the phenomenon of thermal expansion and contraction of the siphonic drainage gutter rainwater hopper due to temperature effects, which may cause the separation of the siphonic rainwater hopper from the bottom of the gutter and lead to water leakage problems. When the "icicle" and other shapes formed by the freezing of the upper eaves of the gutter of this invention melt in winter and suddenly fall, it will cause a certain degree of damage to the gutter structure, resulting in gutter water leakage problems, ensuring that the gutter realizes a full range of snow melting and ice thawing treatment; at the same time, it also solves the problems of poor snow melting coverage area of the gutter, insignificant snow melting effect and energy conservation;

[0043] 10. A heat-conducting plate with a "snake-shaped" groove is provided on the surface of the gutter body. At the same time, an electric tracing band is laid in the "snake-shaped" groove of the heat-conducting plate to increase the coverage area of the tracing band in the gutter, solving problems such as small heat generation area coverage of the electric tracing band on the gutter surface and energy conservation. The material of the heat-conducting plate can preferably be materials with good heat-conducting properties such as metal and ceramics. Using fewer electric tracing bands can evenly generate a large area of heat to cover the entire gutter, melting snow and ice in time during snowy and icy weather. If the area of the gutter is small, the area ratio of the "snake-shaped" groove heat-conducting plate can be appropriately reduced, and a "snake-shaped" groove is arranged inside. The purpose of this device is to generate a large area of heat on the gutter surface with fewer electric tracing bands, achieving the effect of melting snow and ice in time on the basis of energy conservation;

[0044] 11. An intelligent spraying component is provided on the inner wall of the gutter, which can remove snow in the gutter in winter and cool the gutter in summer. The intelligent spraying component is composed of a pipeline, high-pressure nozzles, a snowfall sensor, and an automatic spraying control module. The pipeline is installed on both inner walls at a distance of 0.1 - 0.3 m from the bottom of the gutter. Multiple high-pressure nozzles are designed and installed on the pipeline, and the interval distance of the high-pressure nozzles is such that they are evenly distributed on the inner wall of the gutter. The pipeline is also connected to a snowfall sensor and an automatic spraying control module. The snowfall sensor can sense the snowfall amount and temperature. In winter when it snows and the temperature is below 0°C, when the snowfall sensor receives a signal, it controls the automatic spraying control module to spray snow-removing substances (the snow-removing substances can be brine or snowmelt agents, etc.). It can also control the water spraying amount according to the snowfall amount. Especially when it suddenly snows in the middle of the night, the system will work immediately to prevent snow from freezing in the gutter. In hot summer weather, it can be set to control the automatic spraying control module within a certain temperature range to spray clean water for cooling, protecting the components and extending the service life.

Detailed implementation manners

[0074] 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. Obviously, 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.

[0075] Refer to Figure 1 , a roof system, including a roof body 2 that can form a flat roof or a corrugated roof, such as Figure 1The shown roof is composed of a corrugated roof body formed by multiple arch shapes, and the positions between adjacent arch shapes are trough positions; while the flat roof is a horizontally shaped roof on the top of a building, which is currently quite common in factories; the roof body 2 is laid on the roof columns 1, and the roof columns 1 are the support columns required for building the roof body 2 and have been built before creating the roof, belonging to the current conventional technology; a gutter system 4 is installed at the trough position of the corrugated roof or on the flat roof. For a small-sized flat roof gutter, it can be installed at the edge of the flat roof, and when the flat roof is relatively large, several gutters can be set in the middle of the roof for draining the flat roof.

[0076] Refer to Figure 1 , a skylight system 3 is also installed on the flat roof area, ridge area or sloping roof area of the roof body 2. Specifically, the installation position of the skylight system 3 also depends on the construction site environment and actual usage, and this application does not make a limitation. Only several possible installation positions of the skylight system 3 are given (such as Figure 1 shows that in the case of an arched roof, the skylight system 3 can be installed at the ridge or on the sloping roof. The specific installation quantity and position are determined according to the actual situation), and in the case of a flat roof, the skylight system 3 is installed as required.

[0077] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the roof body 2 of this 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 on-site installation situation; it is assembled by several groups of roof modules 21. Figure 1 What is given is the figure after the complete assembly of three groups of roof modules 21, and Figure 2 is a partial disassembly diagram after the assembly of three groups of roof modules 21 for easy observation. Figure 3 is a partial disassembly diagram after the assembly of the arched roof; it should be noted that the roof has a flat roof (such as Figure 2 shown), or an arched roof (such as Figure 3 shown) or an arched roof (such as Figure 1 shown). Therefore, several groups of roof modules 21 can be assembled into a flat roof, an arched roof or a combination of the two. And the specific number of groups of roof modules 21 to be set depends on the actual size of the roof; during the assembly process, adjacent two groups of roof modules 21 are spliced through a connecting plate 22, and a bridge-shaped reinforcement 23 is clamped above the connecting plate 22.

[0078] Refer to Figure 5, the roof module 21 includes support beams 211, lower roof panels 212, reinforcement components 213, upper roof panels 214, thermal insulation and vapor barrier components 215, mounting brackets 216, solar panels 217, and self-locking components 218. Among them, the support beams 211 are located at the bottom, used to connect the roof columns 1, and together with the roof columns 1, support the lower roof panels 212 and the equipment thereon. Two to three support beams 211 can be laid along the span direction of the lower roof panels 212, and they can be connected to the lower roof panels 212 by bolts or welding to ensure their stability; the reinforcement components 213 are installed on the top of the lower roof panels 212, and the thermal insulation and vapor barrier components 215 are located between the reinforcement components 213, which can play a role in thermal insulation and waterproofing for the lower roof panels 212; and the upper roof panels 214 are locked by the self-locking components 218 above the reinforcement components 213, where the upper roof panels 214 are located on the top of the thermal insulation and vapor barrier components 215; two groups of parallelly distributed mounting brackets 216 are installed on the top of the self-locking components 218, and the solar panels 217 are installed on the top of the two groups of mounting brackets 216.

[0079] It should be noted that the thermal insulation and vapor barrier components 215 are, from bottom to top, a vapor barrier layer, a thermal insulation layer, and a waterproof layer, providing vapor barrier, thermal insulation, and waterproof effects for the lower roof panels 212. (The thermal insulation and vapor barrier components 215 have the same structure as the waterproof reinforcement components 24, which are, from bottom to top, a vapor barrier layer, a thermal insulation layer, and a waterproof layer); at the same time, the lower roof panels 212 are made of color steel plates, and the upper roof panels 214 are made of aluminum-magnesium-manganese plates, which are the best choices.

[0080] It should be noted that when assembling two adjacent roof modules 21, there are two installation methods. One is the splicing of two adjacent roof modules 21 along the roof span direction, and the other is the splicing of two adjacent roof modules 21 along the direction perpendicular to the roof span (as shown in Figure 4 and Figure 5 ). The connecting plates 22 have the same structure as the lower roof panels 212, and both ends of them are provided with edges and are pleated in the middle.

[0081] When two adjacent sets of roof modules 21 are spliced along the roof span direction, the two lower roof panels 212 located below are overlapped up and down, that is, one lower roof panel 212 is placed on top of the other lower roof panel 212. This method helps with waterproofing and water drainage. A waterproof reinforcement component 24 is laid between the two sets of reinforcement components 213 in the middle. The two upper roof panels 214 located above are connected by a connecting plate 22. During installation, the two ends of the connecting plate 22 exactly overlap the two adjacent upper roof panels 214, that is, they are stacked above the upper roof panels 214. The edges of the two ends of the connecting plate 22 are also overlapped up and down, and the overlapping part at both ends (i.e., the two side edges) is fixed by a self-locking component 218, thus realizing the splicing of the connecting plate 22 and the two sets of roof modules 21. Above the overlapping part of the upper roof panel 214 and the connecting plate 22, a bridge-shaped reinforcement member 23 is used for fixation. The middle of the bridge-shaped reinforcement member 23 is arc-shaped and in a downward-bending state at the middle part. The two ends are buckled onto the upper roof panel 214 or the connecting plate 22, providing a squeezing force for the upper roof panel 214 and the connecting plate 22 so that they can better withstand the wind uplift effect. Before installing the connecting plate 22, a waterproof reinforcement component 24 needs to be laid at the bottom of the connecting plate 22 and above the lower roof panel 212 to improve the waterproof performance between the two sets of roof modules 21;

[0082] When two adjacent sets of roof modules 21 are spliced along the direction perpendicular to the roof span, the two lower roof panels 212 located below are also overlapped up and down (the same as the splicing method along the roof span direction mentioned above). The two sets of reinforcement components 213 in the middle are connected to ensure that the reinforcement components 213 of the entire roof are finally connected into one body. The two adjacent upper roof panels 214 located above are also stacked up and down, and then both overlapping parts are fixed by self-locking components 218.

[0083] Refer to Figure 6 and Figure 7, the reinforcement component 213 includes a fastening beam 2131, a sliding rod 2132 and a slider 2133. The fastening beam 2131, the sliding rod 2132 and the slider 2133 form a frame-like structure and are located at the middle position on the top of the lower roof panel 212. Among them, two groups of fastening beams 2131 are provided and are laid parallel on the lower roof panel 212. A number of sliders 2133 are installed on each group of fastening beams 2131, and the slider 2133 can slide back and forth on the fastening beam 2131. At the same time, the fastening beam 2131 can be selected as an I-beam, and the upper and lower limits of the slider 2133 and the fastening beam 2131 can be realized. This process can be adjusted accordingly according to the needs of the staff. The sliding rod 2132 is also provided with several groups, and both ends of each sliding rod 2132 are detachably connected to the sliders 2133 on the two groups of fastening beams 2131. After installation, the sliding rod 2132 and the fastening beam 2131 are vertically distributed, and several groups of sliding rods 2132 are parallel to each other. It should be noted that the specific number of groups of sliders 2133 provided on each group of fastening beams 2131 depends on the on-site installation situation; similarly, the specific number of groups of sliding rods 2132 also depends on the on-site installation situation.

[0084] Further, 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 2131. A steel groove 21333 is opened at the bottom of the slider 2133. The steel groove 21333 is just slidably connected to the fastening beam 2131. Butterfly pin holes 21331 are also opened on the left and right sides of the slider 2133. The butterfly pin holes 21331 are structures with wide ends and narrow middle. This shape has good stability. Among them, the butterfly pin holes 21331 and the positioning pin holes on the fastening beam 2131 are locked by a butterfly pin 21332. During the assembly process, when the staff needs to adjust the distance between two adjacent sliding rods 2132, the distance between the two sliders 2133 on the fastening beam 2131 can be adjusted, that is, the slider 2133 is slid on the fastening beam 2131 for adjustment. After adjusting to the required position, use the butterfly pin 21332 to lock the slider 2133 and the fastening beam 2131.

[0085] It should be noted that the side cross-section of the fastening beam 2131 is in an I-shaped structure. Fastening grooves are opened at both ends of the fastening beam 2131, and the fastening grooves are half grooves for the butterfly pin 21332. When two fastening beams 2131 are spliced, the ends of the two fastening beams 2131 both extend into the slider 2133. Then, insert the butterfly pin 21332 into the butterfly pin holes formed by the fastening grooves on the two fastening beams 2131, and the fixation of the two fastening beams 2131 can be realized (such as Figure 7It can be seen that there is a fastening groove at the end of the fastening beam 2131), so as to complete the connection and fixation between two adjacent fastening beams 2131. Adopting this structure can greatly increase the stability between two adjacent fastening beams 2131, further realizing the connection between adjacent roof panels, with high flexibility, strong practicability, and simple installation, which can greatly speed up the construction speed.

[0086] Furthermore, referring to Figure 6 and Figure 7 , serrated sliding strips 21321 are provided on the side walls at both ends of the sliding rod 2132; a groove 21336 is formed at the top of the slider 2133, and the groove 21336 is exactly slidably connected to the sliding rod 2132. Serrated pin holes 21335 are formed on both the front and back sides of the slider 2133. The serrated pin holes 21335 and the serrated sliding strips 21321 are locked by serrated pins 21334. During the assembly process, when the staff needs to adjust the distance between two adjacent sliders 2133, the length of the sliding rod 2132 between the fastening beams 2131 can be adjusted, that is, the sliding rod 2132 is slid within the slider 2133 for adjustment. After adjusting to the required position, the slider 2133 and the sliding rod 2132 are locked by the serrated pin 21334.

[0087] Referring to Figures 9 - 13 , the self-locking assembly 218 includes an outer clamping member 2181 and an inner clamping member 2182. The outer clamping member 2181 includes an inner clamping groove, and the inner clamping member 2182 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 2181 wraps the inner clamping member 2182 from above, realizing double clamping and self-locking, that is, not only the inner part of the outer clamping member 2181 and the inner clamping member 2182 is clamped by the inner clamping groove and the clamping key, but also the outer part of the outer clamping member 2181 wraps the inner clamping member 2182, thereby realizing double self-locking of the self-locking assembly 218 and ensuring the stability of the self-locking assembly 218; clamping grooves are formed on the inner sides of both the outer clamping member 2181 and the inner clamping member 2182. A fixed support 2183 is clamped in the support clamping groove formed by the two groups of clamping grooves, that is, the outer contour of the fixed support 2183 is adapted to the support clamping groove. The two side edges of the upper roof panel 214 are limited between the support clamping groove and the fixed support 2183. It should be noted that the support clamping groove is composed of an upper part and a lower part. The upper part is a fan-shaped groove, and the lower part is a rectangular groove (as shown in Figure 12 and Figure 13 ).

[0088] Further, when the self-locking assembly 218 and the fixed support 2183 lock the upper roof panel 214 and the connecting plate 22, the ends of the upper roof panel 214 and the connecting plate 22 can wrap around the outside of the fixed support 2183. At this time, the fixed support 2183 supports the upper roof panel 214 and the connecting plate 22 from the inside, and then the outer clamping member 2181 and the inner clamping member 2182 fix the upper roof panel 214, the connecting plate 22 and the fixed support 2183 from both sides, that is, the outer clamping member 2181 and the inner clamping member 2182 fix the upper roof panel 214 and the connecting plate 22 from the outside; it should be noted here that two layers of connecting plates 22 or adjacent roof panels can be stacked on the top of the upper roof panel 214, and then locked by the self-locking assembly 218. This situation can be seen when two adjacent roof modules are spliced. From Figure 4 it can be seen.

[0089] Referring to Figure 12 , the fixed support 2183 includes a positioning horizontal plate and a limiting vertical rod vertically arranged on the positioning horizontal plate; the limiting vertical rod has an upper-wide and lower-narrow structure, and the diagonal triangular gusset plates on both sides of its bottom are fixed to the positioning horizontal plate. The top of the limiting vertical rod 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 the multi-section structure is integrally formed with the limiting vertical rod.

[0090] Figure 13 Another implementation manner of the fixed support 2183 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.

[0091] As Figure 8 shown, the side edge of the upper roof panel 214 is adapted to the shape of the limiting vertical rod, and its top is also an arc-shaped protrusion. An inner concave section and a protrusion section are sequentially arranged downward along both sides of the arc-shaped protrusion, and the multi-section structure is integrally formed with the upper roof panel 214.

[0092] Referring to Figure 10 , both sides of the solar panel 217 are embedded and installed in the nested plate 219. There are two groups of nested plates 219, which are respectively detachably installed above the two groups of mounting brackets 216. It should be noted that the outside of the nested plate 219 is also fixed to the opening on the mounting bracket 216 by bolts through an L-shaped connecting plate, which increases the stability of the nested plate 219. Using the optical storage direct current flexible technology, on the premise of meeting the national technical standards, the solar panels are fixed on the top of the self-locking assembly 218 by the nesting method to achieve "energy storage" and "power supply", so that the building's electricity demand changes from rigid to flexible.

[0093] Referring to Figure 14 , Figure 19 and Figure 21, when the skylight is applied to a corrugated roof, since the heights of various regions of the corrugated roof are different, it should be noted that the height at the ridge of the corrugated roof is the highest, and the negative wind pressure it bears is the greatest. Therefore, in this application, pressure relief and adjustment devices 32 are provided at the four corner positions of the skylight 31 at the ridge. Since the negative wind pressure at the ridge is the greatest, setting the pressure relief and adjustment device 32 at the ridge is the optimal embodiment (as Figure 14 shown), which can balance the negative wind pressure borne by the skylight 31 at the ridge. When a linear mutation occurs at the ridge, the pressure relief and adjustment device 32 is more suitable for the skylight at the ridge, which can balance the negative wind pressure borne by the skylight 31. When the generated negative wind pressure exceeds the pressure set by the pressure relief and adjustment device 32, pressure relief can be carried out through the pressure relief and adjustment device 32. When the generated negative wind pressure is lower than the pressure set by the pressure relief and adjustment device 32, the skylight has been damaged. At this time, the elastic member in the pressure relief and adjustment device 32 pops up the pressure relief device and opens the pressure relief hole for pressure relief, ensuring that the skylight at the ridge has good load-bearing performance; of course, pressure relief and adjustment devices 32 can also be provided for the skylight 31 in the sloping roof area of the corrugated roof and the flat roof (as Figure 18 and Figure 20 shown), and whether to install and the installation position are determined according to the actual installation situation.

[0094] Furthermore, a pressure sensor 35 is also provided inside the skylight 31, and the pressure sensor 35 can monitor the wind pressure borne by the skylight 31 in real time.

[0095] Referring to Figure 14 and Figure 15 , the pressure relief and adjustment device 32 includes a square pipe 321, an elastic member 322, a pressure relief hole 323, a support plate 324, a single plate 325, an inner sleeve rod 326, and an outer sleeve 327. The top of the inner sleeve rod 326 is connected to the square pipe 321, the bottom of the outer sleeve 327 is fixed to the lower roof panel 212, the bottom of the inner sleeve rod 326 is slidably connected inside the outer sleeve 327, and a pressure relief hole 323 is opened on the outer sleeve 327. Among them, the top of the outer sleeve 327 is connected to the square pipe 321 through the elastic member 322, the top of the square pipe 321 is fixed to the skylight 31, one end of the single plate 325 is connected to the square pipe 321 through the support plate 324, the square pipe 321 is arranged on the side of the skylight 31, and a gasket is also provided at the contact position between the inner sleeve rod 326 and the outer sleeve 327. The gasket is fixed on the inner wall of the outer sleeve 327 and is located below the pressure relief hole 323. Here, the gasket can be a sealing gasket to prevent water from entering the gap between the inner sleeve rod 326 and the outer sleeve 327 and affecting subsequent use. When the inner sleeve rod 326 slides upward inside the outer sleeve 327, the pressure relief hole 323 will be exposed, and at this time, pressure relief can be achieved. When the inner sleeve rod 326 slides downward inside the outer sleeve 327, the pressure relief hole 323 will be blocked, and at this time, sealing can be achieved.

[0096] When the external negative wind pressure acts on the skylight 31 at the ridge, it will drive the skylight 31 at the ridge to move upward as a whole, and then drive the inner sleeve rods 326 on both sides of the skylight to slide upward in the outer sleeve 327. When the pressure relief holes 323 on the inner sleeve rods 326 are exposed, the negative wind pressure of the skylight 31 can be relieved through the pressure relief holes 323 at this time. The outer sleeve 327 is connected to the square pipe 321 through the elastic member 322. When the skylight 31 moves upward under the action of the external negative wind pressure, the skylight 31 will drive the elastic members 322 on both sides to stretch at this time. After the pressure relief is over, it will reset under the action of the elastic member 322. And when the pressure sensor 37 detects that the negative wind pressure exceeds the pressure set by the pressure relief device, that is, the elastic member 322 works to drive the skylight 31 to move upward as a whole, and the pressure is relieved through the pressure relief holes. When the generated negative wind pressure is lower than the pressure set by the pressure relief regulating device 32, the skylight may have been damaged. At this time, the elastic member 322 in the pressure relief regulating device 32 manually controls the pressure relief device to bounce up and opens the pressure relief holes to relieve the pressure, ensuring that the skylight at the ridge has good load-bearing performance. It should be noted that the elastic member 322 can be selected from ordinary springs or shock absorbers. The top of the single plate 325 is fixed to the skylight 31, and the single plate 325 and the skylight 31 can be fixed by bolts, pins or welding.

[0097] Referring to Figure 14 , the first flashing 34 includes four groups, which are respectively installed on the four sides of the skylight 31, and the top of the first flashing 34 is fixed to the outer sleeve 327, and there is a gap between the bottom and the lower roof panel 212. The setting of the first flashing 34 can play a certain waterproof effect on the connection between the skylight 31 and the lower roof panel 212. At the same time, the four sides of the bottom of the skylight 31 and the lower roof panel 212 are fixed by the first anti-seepage component 33. The setting of the first anti-seepage component 33 can further ensure the waterproof effect at the connection between the skylight 31 and the lower roof panel 212.

[0098] Further, referring to Figure 16 , the first anti-seepage component 33 includes a corrugated plate 331 and a corner splicing part 332. The corrugated plate 331 is located at the bottom of the side of the skylight 31. One end of the corrugated plate 331 is welded and fixed to the skylight 31, and the other end is welded and fixed to the lower roof panel 212. And the corner splicing part 332 is used to fix the corner splicing place between two adjacent corrugated plates 331. The corner splicing part 332 is exactly located at the four corner positions of the skylight 31, that is, the four corner splicing parts 332 are used to connect the corrugated plates 331 on the four sides, so as to ensure the sealing performance between the entire skylight 31 and the lower roof panel 212.

[0099] Still further, referring to Figure 17 and Figure 18, the corrugated plate 331 includes an integrally formed skylight welding part 3311, a vertical overlapping part 3312, a corrugated convex part 3313 and a roof welding part 3314. The skylight welding part 3311 is fixed to the bottom side of the skylight 31, and the roof welding part 3314 is fixed to the lower roof panel 212. The corrugated convex part 3313 and the roof welding part 3314 are both arranged at both ends of the corrugated plate 331. The roof welding part 3314 is used to weld the roof, and the corrugated convex parts 3313 of two adjacent corrugated plates 331 are fixed by a corner splicing part 332, and the two can be fixedly installed by bolts or welding, etc.; the two adjacent vertical overlapping parts 3312 are also fixed by the corner splicing part 332, and the vertical overlapping part 3312 overlaps on the corner splicing part 332, and the two can also be fixedly installed by bolts or welding, etc. The corner splicing part 332 includes an upper connecting part 3321 and an arc overlapping part 3322. The upper connecting part 3321 is arranged at the top of the arc overlapping part 3322, and the upper connecting part 3321 includes two welding edges in a vertical shape. The two welding edges are welded to the bottom of the corner of the skylight 31. The arc overlapping part 3322 connects two adjacent corrugated convex parts 3313 and is fixedly welded to the corrugated convex part 3313. It should be noted that the corrugated convex part 3313 is an uneven corrugated structure. At the same time, the positions where the arc overlapping part 3322 is connected to the corrugated convex parts 3313 on both sides also adopt corresponding uneven corrugated structures and exactly match the corrugated convex parts 3313 on both sides, increasing the contact area between the two and ensuring the stability and waterproof effect during welding. The bottom of the arc overlapping part 3322 is welded to the roof.

[0100] Referring to Figure 19 , the skylight 31 applied to the pitched roof (or the pitched roof) further includes a second anti-seepage component 36 arranged at the joint between the skylight 31 and the uphill of the pitched roof (as Figure 19 shown). Since the rainwater flows down along the pitched roof from the top of the roof ridge and will concentrate at the joint between the skylight 31 and the uphill of the pitched roof, the second anti-seepage component 36 is arranged at the joint between the skylight 31 and the uphill of the pitched roof, which can prevent the rainwater flowing from the uphill to the downhill from affecting the seal between the skylight 31 and the roof panel, thereby preventing the risk of roof leakage. With this setting, the second anti-seepage component 36 can play a primary role in blocking water between the skylight 31 and the roof panel, while the first anti-seepage component 33 between the skylight 31 and the roof panel plays a secondary role in blocking water, further ensuring the seal between the skylight 31 and the roof panel.

[0101] Further, referring to Figure 20, the anti-seepage component II 36 includes an anti-seepage plate 361 and an anti-seepage splicing plate 362. One end of the anti-seepage plate 361 is fixed to the side of the skylight 31 by welding or bolts, and the other end is fixed to the lower roof panel 212 through the anti-seepage splicing plate 362. The top of the anti-seepage splicing plate 362 is welded to the anti-seepage plate 361, and the bottom of the anti-seepage splicing plate 362 is welded to the lower roof panel 212. The anti-seepage plate 361 is in a "C" shape structure, where the arc opening of the "C" shape faces the upper slope surface. This installation layout is not easy to store water. The anti-seepage splicing plate 362 is in an "S" shape structure, and it can also be set in a "C" shape or other shapes, which is specifically determined according to the actual situation on site. This application Figure 19 gives an "S" shape structure, and the "S" shape structure in this application is the optimal implementation mode. By setting an "S" shape anti-seepage splicing plate between the "C" type anti-seepage plate and the roof, compared with a right-angle connector, the connection at the "S" shape anti-seepage splicing plate is smoother, reducing the connection misalignment caused by stress concentration. Rivet connection can also be used at the joints of the "S" shape anti-seepage splicing plate, the "C" type anti-seepage plate and the roof. Specifically, blind rivets can be selected and sealed with sealant to reduce the contact area of the connection between the "C" type anti-seepage plate and the roof, making the connection more reliable.

[0102] Refer to Figure 22 , when the gutter system 4 is on a flat roof, the staff can set several gutters at the edge of the roof or in the middle of the roof according to actual needs to drain water; when the gutter system 4 is on a corrugated roof, the staff can set it at the trough position according to actual needs. At the trough position, the rainwater left on the roof can be discharged from the gutter 41 as a whole without affecting the roof;

[0103] When the gutter 41 is specifically installed, it is set at the eaves of the lower roof panel 212. A rainwater outlet is opened on the inner bottom wall of the gutter 41, and a siphon rainwater bucket 42 is installed at the rainwater outlet. The bottom of the rainwater outlet is connected to a rainwater pipe 49. A rainwater pipe heating tape 46 is arranged inside the rainwater pipe 49 and is connected to a junction box 48 arranged on the inner wall of the gutter. An eaves snow melting and ice melting component 43 is arranged at the upper eaves of the gutter 41 to perform snow melting and ice melting treatment at the roof eaves, preventing ice cones from forming at the eaves and falling into the gutter 41, causing damage to the gutter; a water pressure monitor 44 is arranged on the side wall of the gutter 41 to detect the water pressure inside the gutter 41, and a gutter snow melting and ice melting component is arranged inside the gutter 41, and the gutter snow melting and ice melting component can perform snow melting and ice melting treatment inside the gutter.

[0104] Refer to Figure 27 and Figure 28, the siphonic rainwater hopper 42 includes a conical drainage part 421, a gasket 422, a helical part 423 and a water outlet 424. The top of the helical part 423 is provided with the conical drainage part 421. The gasket 422 is located outside the helical part 423. The helical part 423 is communicated with the water outlet 424 at the bottom. During installation, the helical part 423 is connected with the rainwater pipe. The gasket 422 is closely attached to the rainwater pipe to ensure the seal between the helical part 423 and the rainwater pipe. The water outlet 424 is connected with the rainwater pipe 49. During use, rainwater flows from the conical drainage part 421 into the helical part 423 and then is discharged into the rainwater pipe 49 through the water outlet 424. The arrangement of the rainwater pipe heat tracing belt 46 can heat the rainwater pipe 49 to prevent the rainwater pipe 49 from freezing due to low temperature and causing pipe blockage. It should be noted that by providing threads on the outside of the helical part 423, not only the stability during installation is ensured, but also the temperature effect generated by the heat of the rainwater pipe heat tracing belt 46 in the rainwater pipe 49 at the water inlet can be prevented, and the heat dissipation effect of the siphonic rainwater hopper 42 is enhanced.

[0105] Further, the gasket 422 further includes an expansion layer 4221 and a honeycomb waterproof layer 4222. The expansion layer 4221 and the honeycomb waterproof layer 4222 are integrally formed to form an integral gasket. The expansion layer 4221 is located on the outer ring of the honeycomb waterproof layer 4222. The outermost layer of the gasket 422 is the expansion layer 4221, which has the function of enhancing heat dissipation, and the heat dissipation effect becomes stronger as the thickness of the expansion layer increases; the inner layer is the honeycomb waterproof layer, and a honeycomb layer is provided at the connection with the expansion layer. The honeycomb layer can prevent the breakage from extending when a certain part is damaged, and can ensure the service life of the gasket. It should be noted that the expansion layer material is preferably a mixture of expanded graphite, polyvinyl chloride plasticizer, polyvinyl chloride heat stabilizer and filler.

[0106] Further description of the integral siphonic rainwater hopper gasket:

[0107] Comparative Example 1: The total diameter of the integral siphonic rainwater hopper gasket is 100 mm, and the diameter of the honeycomb layer is about 30 mm.

[0108] Example 2: The total diameter of the integral siphonic rainwater hopper gasket is 100 mm, the diameter of the outermost expansion layer is about 10 mm, and the diameter of the honeycomb layer is about 20 mm.

[0109] Example 3: Similarly, the total diameter of the integral siphonic rainwater hopper gasket is 100 mm, the diameter of the honeycomb layer is 18 mm, and the diameter of the outermost expansion layer is 12 mm.

[0110] Example 4: Similarly, the total diameter of the integral siphonic rainwater hopper gasket is 100 mm, the diameter of the honeycomb layer is 16 mm, and the diameter of the outermost expansion layer is 14 mm.

[0111] Example 5: Similarly, the total diameter of the integrated siphonic rainwater hopper gasket is 100 mm, the diameter of the honeycomb layer is 14 mm, and the diameter of the outermost expansion layer is 16 mm.

[0112] Example 6: Similarly, the total diameter of the integrated siphonic rainwater hopper gasket is 100 mm, the diameter of the honeycomb layer is 12 mm, and the diameter of the outermost expansion layer is 18 mm.

[0113] Heat dissipation capacity test: Examples 1-5 in Table 1 are the test results of the integrated gasket;

[0114]

[0115] It can be seen from Table 1 that the surface temperature change of the gaskets in Examples 2-5 is less than 5 °C, while the temperature rise of Comparative Example 1 without the expansion layer is higher than 10 °C, indicating that the new gasket has good heat dissipation capacity, and with the increase of the expansion layer area, the heat dissipation capacity is better.

[0116] Refer to Figure 22 and Figure 23 , the eaves snow melting and ice thawing assembly 43 is arranged at the top of the roof and at the upper eaves position of the gutter 41. The eaves snow melting and ice thawing assembly 43 includes an eaves plug 431, a heat insulation layer 432, a heat conduction pad 433, a heating cable 434 and a second flashing 435. Among them, the eaves plug 431 is located at the end of the roof, the heat conduction pad 433 and the heat insulation layer 432 are laid in sequence at the end of the roof, the heating cable 434 is located on the heat conduction pad 433, and the heating cable 434 is connected to the solar panel 217 on the roof; among them, the second flashing 435 is arranged below the eaves plug 431, and there is a gap between the second flashing 435 and the lower roof panel 212, and the water flow can flow out from the second flashing 435 through the eaves plug 431 without seeping into the roof and affecting the roof.

[0117] It should be noted that by setting the heating cable 434, i.e., the electric tracing band, at the upper eaves of the gutter, the melting of ice and snow at the upper eaves of the gutter in snowy weather is realized, making it not easy to freeze and form an "ice cone" blocking the upper eaves of the gutter, resulting in the problem that the roof is not easy to drain water in rainy and snowy weather in time. At the same time, it can also avoid the sudden fall of the "ice cone" and other shapes during melting, causing damage to the inside of the gutter. At the same time, in this device, the heating cable 434 is connected to the solar panel 217 on the roof, a heat conduction pad 433 is arranged on the heating cable 434, and heat conduction pads 433 are also arranged at the same distance from the lower contact part of the heating cable 434 to the eaves, strengthening the heat and area generated by the heating cable 434. An insulation layer 432 is arranged at the distance from the eaves plug to the heating cable below the heat conduction pad 433 to avoid the temperature effect caused by the heat transferred by the heat conduction pad 433 from affecting the lower structure. At the same time, the eaves plug 431 can prevent water droplets from seeping into the roof. The solar panel 217 can provide energy for the heating cable 334 and the water pressure monitor 44 inside the eaves snow melting and ice thawing assembly 43.

[0118] Referring to Figure 24 , the gutter snow melting and ice melting component includes a gutter heating tape 471 and a groove formed in the heat conducting plate 410, wherein the groove is in a "snake-shaped" structure, and the gutter heating tapes 471 are all laid in the groove in a snake shape, and the gutter heating tapes 471 are connected to the solar panels 217 on the roof. This method is to melt snow and ice by installing a heating tape in the gutter for heating.

[0119] It should be noted that by forming a "snake-shaped" groove in the heat conducting plate and laying the gutter heating tape 471 in the groove, the gutter heating tape 471 also presents a "snake-shaped" structure, which can increase the coverage area of the heating tape in the gutter 41, solve the problems of small heat generation area and energy saving of the electric heating tape on the surface of the gutter 1. The heat conducting plate material can preferably be materials with good heat conductivity such as metal and ceramic; in this application, fewer electric heating tapes can be used to evenly generate a large area of heat to cover the entire gutter 41, and the snow and ice can be melted in time in snowy and icy weather. If the area of the gutter 41 is small, the area ratio of the "snake-shaped" heat conducting plate can be appropriately reduced, and a "snake-shaped" groove can be arranged inside (as Figure 24 shown, what is given is a schematic diagram of arranging a groove in the gutter and laying a heating tape; and Figure 23 what is given is the situation of arranging two grooves in the gutter and laying two heating tapes). Specifically, how many grooves are formed and how many heating tapes are arranged are determined according to the actual size of the gutter and the requirements on site. This application does not make any limitations, and only two implementation manners are given. The purpose of this device is to use fewer electric heating tapes to generate a large area of heat on the surface of the gutter, and achieve the effect of timely melting of snow and ice on the basis of energy saving.

[0120] Referring to Figure 26, in another embodiment, the rest is the same as above, the difference is that: the gutter snow melting and ice melting component includes an intelligent spraying member 472, and the intelligent spraying member 472 further includes a pipeline 4721, a high-pressure nozzle 4722, an automatic spraying control module 4723 and a snowfall sensor 4724. Among them, a number of high-pressure nozzles 4722 are provided and evenly laid on the side wall of the gutter 41. The number of high-pressure nozzles 4722 is connected through the pipeline 4721. It should be noted that the specific number of high-pressure nozzles 4722 is determined according to the size of the gutter and the actual installation situation, and this application does not make a limit here; the automatic spraying control module 4723 and the snowfall sensor 4724 are arranged at the end of the side wall of the gutter 41. One end of the pipeline 4721 is connected to the deicing agent box. The deicing agent is brine or snow melting agent. Under the control of the automatic spraying control module 4723, the deicing agent in the deicing agent box can be automatically transported into the pipeline 4721, and then sprayed into the gutter by the high-pressure nozzle 4722 to realize snow melting and ice melting in the gutter. This method is to install brine spraying or snow melting agent spraying in the gutter to realize snow melting and ice melting treatment. It should be noted here that the intelligent spraying solution here is a reinforcement based on the heat conduction plate 410. The gutter heating tape 471 can emit a large amount of heat on the heat conduction plate 410 to melt snow and ice, and the substances such as brine and snow melting agent sprayed by the intelligent spraying can also melt snow and ice, so as to enhance the snow melting effect in the gutter.

[0121] It should be noted that by setting the intelligent spraying member 472, it can play the role of removing snow in the gutter in winter and cooling the gutter in summer. The pipeline 4721 is installed on the inner walls on both sides 0.1-0.3 m away from the bottom of the gutter. Its specific installation height is determined according to the on-site installation situation or the actual size of the gutter. This application does not make a limit, and only gives a preferred range value for reference; the pipeline 4721 of this application is connected to the snowfall sensor 4724 and the automatic spraying control module 4723 at the same time. The snowfall sensor 4724 can sense the snowfall amount and temperature. When it snows in winter and the temperature is below 0°C, after the snowfall sensor 4724 receives the signal, it controls the automatic spraying control module to spray deicing agent, etc., and can also control the water spraying amount according to the snowfall amount. Especially when it suddenly snows in the middle of the night, the system will work immediately to prevent the snow from freezing in the gutter. In hot summer weather, it can be set to control the automatic spraying control module 4723 within a certain temperature range, and clean water can be sprayed to cool down, protect the components and extend the service life. While melting the snow and ice in the gutter, this equipment will not cause a temperature difference on the metal roof, and can effectively prevent the connection parts of the metal roof from leaking and becoming loose due to the temperature effect.

[0122] Inside the roof, there is a roof machine box. Inside the roof machine box, there are an inverter, an energy storage module, a load, a water pressure signal transmission module, and a heating control module, which are connected in sequence from top to bottom. The inverter is connected to the solar panel 217. The inverter converts the direct current generated by the solar panel 217 into alternating current. The energy storage module is used to store the electric energy converted by the inverter and deliver the electric energy to the electrical load. The heating control module controls the working state, heating time, and temperature adjustment of the electric tracing tapes at various locations. The water pressure signal transmission module is connected to the water pressure monitor 44. The water pressure signal transmission module is used to transmit the water pressure value in the gutter detected by the water pressure monitor 44. When the detected gutter water pressure value is abnormal, inspection and maintenance are carried out in a timely manner.

[0123] The specific installation principle of the roof body of this application is as follows:

[0124] Before assembly, ① First, 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 column 1 and meet the load requirements. And temporary assembly rails need to be set on the roof column beams of the factory building. ② The steel structure factory building is arranged in zones and assembled in zones. 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 are set on the roof column beams so that the roof module can be slid to the designated position for bolt fixation.

[0125] 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 column. When installing, the staff transports the parts to the platform and then directly assembles above the assembly platform, which is convenient for the overall module to be placed on the roof column. Since the assembly platform is not the solution to be protected by this application and the assembly platform is relatively conventional in the current construction site, this application uses the assembly platform, so a simple introduction is made here.

[0126] The method for assembling a single roof module of this application:

[0127] During assembly, transport the prefabricated parts of the factory roof module 21 to the site and assemble a single roof module 21 on the assembly platform. First, install the lower roof panel 212 above the support beam 211, and install sliding shoes at the bottom of the support beam 211. The sliding shoes can slide on the slide rails. Then, lay the fastening beam 2131, slider 2133, and sliding rod 2132 above the lower roof panel 212 in sequence and lock the three of them. Subsequently, install the self-locking component 218 above the sliding rod 2132 and use the self-locking component 218 to fix the upper roof panel 214. Place the thermal insulation and vapor barrier component 215 at each gap between the fastening beam 2131 and the sliding rod 2132. The thermal insulation and vapor barrier component 215 consists of a vapor barrier layer, a thermal insulation layer, and a waterproof layer from bottom to top. Finally, install the solar panel 217 above the self-locking component 218. Slide the assembled single roof module 21 to the designated position on the roof along the slide rails on the roof columns. Then, use a jack to lift the roof module. The jack lifts the upper support beam 211 of the module and slowly place the whole module on the roof columns, and then fix it integrally. Remove the sliding shoes and the corresponding segmented slide rails, and then fixedly connect the roof module 21 to the roof column 1. 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 slide rails are also placed on the temporary columns. The sliding steps are the same as the previous ones. After the two side unit roofs are simultaneously slid to the designated positions, then bolt the bottom support beams 11 on both sides, and use a jack to remove some of the slide rails.

[0128] Subsequently, lay the waterproof reinforcement component 24 at the joint of two adjacent roof modules 21, and connect the two roof modules 21 with a connecting plate 22 above the waterproof reinforcement component 24. Pay attention to the arrangement of the size and the staggered lap of the front and rear roof panels during assembly. If the factory building span is too large, install multiple modules and then perform integral sliding installation. At the same time, it is necessary to check the load stability of the assembly platform. When the factory building span is too large, use the temporary steel columns described above for assistance, and the steps refer to the description of the temporary steel columns above. Perform the above steps in sequence to assemble the overall roof in blocks, slide it to the designated position, and perform fine adjustment of the roof through the fine adjustment system between the fastening beam 2131, sliding rod 2132, and slider 2133 within the roof system itself to achieve the overall roof effect.

[0129] When the roof body 2 is being assembled, the staff also needs to install and arrange the skylight system 3 and the gutter system 4 as required. The specific installation positions and quantities depend on the on-site conditions, the size and shape of the roof body 2, etc.

[0130] When the skylight system 3 is installed and in use, in rainy weather, when the external negative wind pressure acts on the roof, different wind pressures will be generated at different positions on the roof. The negative wind pressure at the ridge is the largest, so the skylight 31 set at the ridge will also be correspondingly affected by the largest negative wind pressure, which may cause the skylight 31 to move upward. When the negative wind pressure is large, it may even cause the skylight 31 to break; correspondingly, there is the negative wind pressure on the slope surface. The negative wind pressure on the slope surface is not as large as that at the ridge, but there is still the influence of negative wind pressure. Therefore, the pressure relief device is set for the skylight 31 at the flat roof, slope roof and ridge.

[0131] When the external negative wind pressure acts on the skylight 31 at the ridge, it will drive the entire skylight 31 at the ridge to move upward, and then drive the inner sleeve rods 326 on both sides of the skylight to slide upward in the outer sleeve 327. When the pressure relief holes 323 on the inner sleeve rod 326 are exposed, the negative wind pressure on the skylight 31 can be relieved through the pressure relief holes 323 at this time; among them, the outer sleeve 327 is connected to the square pipe 321 through the elastic member 322. When the skylight 31 moves upward under the action of external negative wind pressure, the elastic members 322 on both sides of the skylight 31 will be stretched at this time. After the pressure relief is over, it will reset under the action of the elastic member 322. And when the pressure sensor 37 detects that the negative wind pressure exceeds the pressure set by the pressure relief device, that is, the elastic member 322 works to drive the entire skylight 31 to move upward and relieve pressure through the pressure relief holes; when the generated negative wind pressure is lower than the pressure set by the pressure relief adjustment device 32, the skylight may have been damaged. At this time, the elastic member 322 in the pressure relief adjustment device 32 pops up the pressure relief device manually and opens the pressure relief hole to relieve pressure, ensuring that the skylight at the ridge has good load-bearing performance;

[0132] At the connection between the four sides of the skylight 31 and the lower roof panel 212, it is necessary to ensure good sealing effect. Therefore, an anti-seepage component 33 is set at the connection between the two. Through the cooperation of the corrugated plate 331 and the corner splicing piece 332, the sealing of the connection between the entire skylight 31 and the lower roof panel 212 is realized. And the setting of the corrugated convex part 3313 on the corrugated plate 331 can cause obstacles when rainwater passes through the corrugated convex part 3313. The corrugated convex part 3313 blocks the rainwater multiple times, thereby ensuring the sealing effect at the connection between the skylight 31 and the lower roof panel. At the same time, the first flashing 34 can withstand the rainwater impact from above to the connection between the skylight 31 and the lower roof panel 212. When the rainwater falls on the first flashing 34, it will play a certain buffering role through the first flashing 34 and then slide down from the first flashing 34 to the roof. It should be noted that the anti-seepage component 33 is set for the skylight at the flat roof, slope roof and ridge.

[0133] On the slope surface, especially when it is an uphill surface, rainwater slides down along the slope from the ridge at the highest point. Therefore, further anti-seepage fixation is required for the seal between the skylight 31 and the lower roof panel at the uphill surface. Thus, an anti-seepage component two 36 is added below the first flashing 34 on the uphill surface, and an anti-seepage component two 36 is added at the front end of the anti-seepage component one 33. That is, the rainwater can be blocked for the first time through the anti-seepage plate 361 and the anti-seepage splicing plate 362, and then the rainwater is blocked for the second time through the anti-seepage component one 33, which can further ensure the sealing effect between the skylight 31 on the uphill surface and the lower roof panel.

[0134] When the gutter system 4 is installed and in use, when encountering rain, snow or sleet weather, the rain, snow or sleet will flow along the roof and into the gutter 41 at the roof eaves. Since the gutter 41 is concave and there is a certain height between its interior and the gutter eaves, icicles may form at the upper eaves during rain, snow or sleet weather. Therefore, an eaves snow melting and de-icing component 43 is provided to remove the icicles. During the removal process, the high-temperature snow melting and de-icing treatment can be realized through the setting of the heating cable 434 and the heat conduction pad 433. The melted rainwater can flow into the gutter 41 from the second flashing 435 under the action of the eaves plug 431, thus preventing icicles from forming on the upper eaves of the gutter.

[0135] However, the rainwater falling into the gutter 41 still has the risk of forming ice due to the low outdoor temperature environment, and the snow falling into the gutter may accumulate. Since the gutter is at a high place and it is not easy for manual removal, a gutter snow melting and de-icing component is set in the gutter 41 to realize the snow melting and de-icing treatment inside the gutter 41. During the specific treatment, there are two optional methods. One is to realize the snow melting and de-icing by setting a heating tape inside the gutter, and the other is to realize the snow melting and de-icing by spraying a snow melting agent on the inner wall of the gutter.

[0136] When choosing to use a heating tape to realize the snow melting and de-icing in the gutter, one or two gutter heating tapes 471 can be selected according to the size of the gutter 41 and the actual on-site situation. During rain, snow or sleet weather, the start of the gutter heating tape 471 is controlled by the heating control module in the roof machine box in the house. The gutter heating tape 471 heats the inside of the gutter 41, so as to realize the snow melting and de-icing treatment for the snow or ice blocks inside the gutter. After the snow and ice blocks are melted into rainwater, they can fall from the siphonic rainwater hopper 42. When entering the siphonic rainwater hopper 42, the rainwater pipe heating tape 46 in the rainwater pipe 49 also starts to work. The rainwater pipe heating tape 46 is also controlled by the roof machine box. The rainwater pipe heating tape 46 can prevent the rainwater from freezing in the rainwater pipe 49 in a low-temperature environment. Finally, it falls into the ground through the rainwater pipe 49. Among them, the rainwater pipe heating tape 46 and the gutter heating tape 471 are powered by the solar panel 217.

[0137] When choosing to use the method of spraying snowmelt agent to achieve snowmelt and ice melting, high-pressure nozzles 4722 can be laid inside the gutter 41 according to the size of the gutter 41 and the actual on-site situation. Connect multiple high-pressure nozzles 4722 through a pipeline 4721, and connect an automatic spraying control module and a snowfall sensor 4724. The inlet of the pipeline 4721 is connected to an external snowmelt agent box. When in use, control the automatic spraying control module 4723 to work through the roof machine box. The automatic spraying control module 4723 controls the snowmelt agent in the snowmelt agent box to be input into the pipeline 4721, and then sprayed out from multiple high-pressure nozzles 4722 into the inside of the gutter 41 and act on the ice or snow in the gutter 41, so as to achieve snowmelt and ice melting treatment. After the snow and ice melt into rainwater, it can fall from the siphon rainwater hopper 42. When entering the siphon rainwater hopper 42, the rainwater pipe heat tracing belt 46 in the rainwater pipe 49 also starts to work. The rainwater pipe heat tracing belt 46 is also controlled through the roof machine box. The rainwater pipe heat tracing belt 46 can prevent rainwater from freezing in the rainwater pipe 49 in a low-temperature environment, and finally fall into the ground through the rainwater pipe 49. Among them, the rainwater pipe heat tracing belt 46, the automatic spraying control module 4723 and the snowfall sensor 4724 are powered by the solar panel 217.
