Description

[Technical Field]

[0001] The present invention relates to the field of roofing, and in particular to roofing systems. [Background technology]

[0002] In recent years, due to its advantages of light weight, high thermal insulation, and fast construction speed, rolled metal roofing has been widely used in large-span architectural structures such as train stations, airports, and scientific research factories. Generally, in large-scale steel roofing construction, the purpose is to reduce the number of lap joints in the roofing panels, improve the overall integrity of the roof, and ensure the roof's waterproofing and overall pressure-resistance functions. Rolled metal roofing panels have the advantages of light weight, beautiful appearance, and easy and fast construction, so large-span metal roofing panels are widely used. However, in the prior art, there are many problems.

[0003] In terms of roof construction quality, roof panels are prone to deformation due to insufficient connection at the connection points when the entire roof panel is installed. Furthermore, the connection methods between the individual components of the roof panel generally use mechanical connections such as locking, interlocking, or clamping, resulting in low connection rigidity. Strong wind loads or normal wind loads at specific wind vibration frequencies can result in blow-off accidents. For example, an existing patent document with registration number CN218176365U and patent title "Reinforced Engagement Structure for Metal Roof Panels" specifically discloses that "the structure comprises a ridge cover and a ridge connecting member, and an elastic traction device is attached to the inside of the ridge cover to gather the side panels on both sides of the ridge cover to the center. The ridge cover of this invention uses the inner elastic traction device to gather the side panels on both sides of the ridge cover inward and engage with the buckles on the ridge cover, thereby strengthening the connection strength between the ridge cover and the ridge connecting member and reducing the risk of the ridge cover being blown off by strong winds." Although the above techniques can improve the anti-blow-off function of metal roofing sheets to a certain extent, they always use a multi-point arrangement, and because they are arranged closely together and each point acts independently, the fixing points cannot coordinate to bear the force, resulting in low stability and the risk of falling off in extreme cases. At the same time, they are not safe and easy to install on the roof. Current roofing sheets are generally installed at high altitudes to complete the entire installation at high altitudes, but the installer often faces potential safety issues during the high-altitude work process, and safety is low, and precision control during the installation process is also difficult when installing at high altitudes.

[0004] Skylights are an important part of a roof, and their wind resistance and infiltration prevention capabilities are particularly important. The surface wind pressure distribution of a roof covering is primarily affected by the turbulence inherent in the structure itself, resulting in airflow separation at the highest point of the roof, creating relatively large negative pressure. Relevant simulations were conducted on wind pressure distribution on the roof in different directions. The current Building Structural Loading Standard (GB 50009-2012) also indicates that negative pressure is relatively large at the highest point of the roof. Compared to skylights on flat and sloped roofs, the load-bearing condition of skylights at the ridge is more complex, and the negative wind pressure effect makes the skylight less stable at this point. This makes it difficult to withstand the impact of stronger wind loads, leading to deformation and infiltration problems.

[0005] However, currently, roofs on the market generally do not provide wind-resistant and decompression treatment to counteract wind pressure. Most roofs simply add reinforcement to the ridge. For example, an existing patent document with registration number CN214169604U and patent title "Wind-Resistant and Snow-Proof Ridge Structure for Metal Roofs" specifically discloses that "ridge caps are respectively fixed to two opposing upper rolled metal sheets of the roof, the shape of the ridge caps fits the shape of the troughs of the upper rolled metal sheets of the roof, the ridge caps are connected to the peaks on the upper surface of the upper rolled metal sheets of the roof, and the ridge caps are connected and fixed to the troughs on the upper surface of the upper rolled metal sheets of the roof. Butyl tape is installed at the joints with its leading edge facing the trailing edge, and a gap is left between the two butyl tapes. The use of custom-shaped ridge caps and metal exterior ridge tiles, a special butyl tape installation method, and a unique connection method makes the entire ridge structure of the metal roof more solid and effectively solves the problem of minor wind and snow leakage." However, when faced with strong winds or heavy snowstorms, it is difficult to resist wind loads, and the skylights on the ridge will be deformed. Summary of the Invention [Problem to be solved by the invention]

[0006] The technical problem that the present invention aims to solve is how to solve the problem of low construction quality and construction safety of current roofs and the problem that roof skylights are easily deformed by the influence of wind pressure. [Means for solving the problem]

[Effects of the Invention]

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: First, the present invention involves assembling multiple sets of roof modules to form the roof body, and using connecting plates and self-locking assemblies to secure two adjacent roof modules together during assembly, thereby further ensuring the integrity of the metal roof formwork and the entire roof. Multiple reinforcement points work in unison, with a high utilization rate, ensuring the integrity and support function of the entire roof. Meanwhile, the means of independently prefabricating the modules and then joining them allows for flexible operation and easy installation, further accelerating construction progress and ensuring the safety of the contractor. The installation of self-locking assemblies overcomes the inherent problems of roof panel blow-off prevention, installation precision, and construction safety, ensuring wind resistance for the entire roof system through the coordination of brackets and various reinforcing members. Meanwhile, pressure-reducing assemblies are installed on the skylights, which can effectively address the problem of ridge deformation due to excessive bearing capacity under stronger wind loads. When the resulting negative wind pressure exceeds the set pressure, the pressure-reducing assemblies reduce pressure, thereby ensuring good support performance for the skylights on the roof. Secondly, the present invention uses a self-locking assembly to lock both sides of two adjacent lower roof panels, and the outer engaging member can cover the inner engaging member from the outside, and the protrusion of the inner engaging member engages with the outer engaging member to ensure self-locking between the inner and outer engaging members. Fixing brackets are also provided on the inside of the inner and outer engaging members, so that the fixing brackets can protrude and support the bottoms of both sides of the lower roof panels. Since the inner and outer engaging members lock the lower roof panels from the outside, the soundness of the lower roof panels when they are installed is ensured and the wind resistance of the lower roof panels is improved. The upper cross section of the fixing bracket is larger than the lower cross section, presenting a structure that is wider at the top and narrower at the bottom, and the roof The side edges of the base board also have a similar wide top and narrow bottom structure, and when they fit together, they can effectively resist the negative pressure caused by wind loads (i.e., resist pull-out resistance). At the same time, an inclined triangular bracket is installed at the small cross-section area at the bottom of the fixing bracket, which effectively ensures the bracket's pressure-resistant effect and can reinforce the lower roof board before it is damaged. This solves the problems of the roof board's inherent form of weakness in preventing blow-off, as well as low installation accuracy and construction safety. The overall metal roof system ensures wind resistance through the cooperative action of the bracket and various reinforcing members, greatly improving the structural strength, rigidity and wind resistance of the roof board. Third, multiple sets of positioning pin holes are opened at equal distances on both sides of the fastening beam, and the slide block can slide on the fastening beam, and butterfly pin holes corresponding to the positioning pin holes are opened in the slide block. Therefore, the fastening beam and the slide block can be fixed using the butterfly pins. The worker can move and adjust the slide block by controlling the installation of the butterfly pins, allowing the upper roof panel to move relative to the fastening beam above, and even connecting adjacent roof panels together. This is highly flexible, practical, and easy to install, and can greatly accelerate construction speed. Fourth, in the present invention, the top of the slide block can be slidably connected to the slide bar, and a sawtooth pin hole is opened in the slide block, and a corresponding sawtooth slide bar is installed on the slide bar. Then, the sawtooth pin can pass through the sawtooth pin hole and engage with the sawtooth slide bar, thereby locking the slide block and the slide bar, and also allowing fine adjustment of the slide bar to avoid the problem of the slide block and the slide bar being locked. The position can be easily adjusted, that is, the spacing between the two fastening beams can be adjusted for different lower roof panels to accommodate lower roof panels of different sizes, ensuring efficient connection of subsequent roof panels. This is highly flexible, practical, and easy to install, and can greatly accelerate the construction speed. Fifth, the present invention places a heat insulation and moisture-proof assembly in each gap between the fastening beams and the sliding bars. The heat insulation and moisture-proof assembly consists of a moisture-proof layer, a heat-insulating layer and a waterproof layer from top to bottom. The fastening beams, sliding bars and fixing brackets can support the upper roof board, preventing the heat insulation and moisture-proof assembly from being directly subjected to pressure, thereby ensuring the stability of the structure. When external pressure is applied, the pressure is mainly absorbed by the brackets and reinforcing assembly, improving the overall structure. Sixth, the present application installs slidable jacket pressure reduction assemblies at the four corners of the skylight, which can effectively address the problem of the ridge deformation caused by excessive bearing capacity due to stronger wind loads. At the same time, the jacket is provided with pressure reduction holes, which introduce elastic members and cooperate with pressure sensors. When the generated negative wind pressure exceeds the pressure set in the pressure reduction device, the pressure reduction adjustment device will begin to reduce pressure. Once the pressure reduction is completed, the elastic members will perform a retracting action to immediately close the pressure reduction adjustment device. When the generated negative wind pressure is lower than the pressure set in the pressure reduction device, the skylight may already be at risk of being destroyed. At this time, the elastic members will bounce the pressure reduction device, open the pressure reduction adjustment device, and reduce pressure, thereby ensuring good support performance of the skylight at the ridge. Seventh, this application uses horizontal folded plates to join the four sides of the skylight to the roof. The installation of horizontal folded plates significantly increases the contact area at the joints, making the contact more reliable. The horizontal folds also extend the path for water to seep in at the joint between the skylight and the roof, allowing fast-flowing water to be immediately discharged during heavy rain or heavy snowstorms, thereby effectively improving the waterproofing performance at the joint between the bottom of the skylight and the metal roof panel. Eighth, in this invention, a C-shaped seepage prevention plate is installed at the boundary between the skylight and the slope of the roof, and in cooperation with the dripping plate, the seepage point is moved upward, thereby effectively solving the seepage phenomenon caused by rainwater accumulating at the joint between the skylight and the slope of the roof in heavy rain or heavy snowstorm conditions. An S-shaped seepage prevention joint plate is installed between the C-shaped seepage prevention plate and the roof. The installation of the S-shaped seepage prevention joint plate allows for a smooth transition at the connection point, reducing connection misalignment caused by stress concentration. The connection points of the C-shaped seepage prevention plate, the S-shaped seepage prevention joint plate and the roof are riveted and sealed with sealant, thereby reducing the contact area between the C-shaped seepage prevention plate and the roof and making the connection more reliable. Ninth, in this invention, an eave snow melting and thawing assembly is installed on the upper eaves of the gutter, and a gutter snow melting and thawing assembly is also installed inside the gutter. Solar panels supply electrical energy to the two snow melting and thawing assemblies to melt and thaw the snow and ice on the upper eaves of the gutter and inside the gutter. A siphon roof drain is installed at the rainwater outlet inside the gutter, rainwater pipe tracing tape is installed inside the siphon roof drain, and a spacer is attached to the siphon roof drain. This prevents the drain bucket of the siphon drain gutter from thermally expanding and contracting due to temperature effects, which can cause the siphon roof drain to separate from the bottom of the gutter and lead to seepage problems. In this invention, the problem of "icicles" that form on the upper eaves of the gutter in winter suddenly falling when they melt can cause some damage to the gutter structure and further lead to water leakage in the gutter. This ensures that the gutter can achieve snow melting and thawing in all directions, and also solves the problem of the gutter's small snow melting coverage area, which causes the snow melting effect to be unclear, and saves energy. Tenth, a heat conduction plate with a "snake-shaped" groove is installed on the surface of the gutter body, and electrical tracing tape is laid in the "snake-shaped" groove of the heat conduction plate, thereby increasing the area covered by the tracing tape within the gutter, solving the problem of the electrical tracing tape's small area coverage for heat generation on the gutter surface and saving energy. The material of the heat conduction plate can preferably be a material with higher thermal conductivity, such as metal or ceramic, so that less electrical tracing tape is needed to generate heat evenly over a large area and cover the entire gutter, quickly melting ice and snow in icy and snowy weather. If the area of ​​the gutter is smaller, the area ratio of the "snake-shaped" groove to the heat conduction plate can be appropriately reduced and a single "snake-shaped" groove can be installed inside. This device is intended to generate heat over a large area on the gutter surface with less electrical tracing tape, achieving the effect of quickly melting ice and snow while saving energy. Eleventh, by installing an intelligent spray element on the inner wall of the gutter, it is possible to remove snow from the gutter in winter and reduce the temperature inside the gutter in summer. The intelligent spray element is composed of a pipe, a high-pressure nozzle, a snow sensor and an automatic spray control module. The pipes are installed on the inner wall on both sides, 0.1 to 0.3 m away from the bottom of the gutter. A number of high-pressure nozzles are designed and installed on the pipes. The high-pressure nozzles are uniformly spaced on the inner wall of the gutter. The snow sensor and the automatic spray system are simultaneously connected to the pipes. The snow sensor detects the amount of snow and the temperature. When it snows in winter, or when the temperature is below 0°C and snow falls, the snow sensor receives a signal and controls the automatic spray control module to spray snow removal material (the snow removal material may be salt water or snow-melting agent, etc.), and the amount of water sprayed can be controlled based on the amount of snowfall. In particular, when snow falls suddenly in the middle of the night, the system will immediately operate to prevent snow from freezing in the gutters. In hot summer weather, the automatic spray system may be set to control the spraying of fresh water to cool down the components within a certain temperature range, thereby protecting them and extending their service life.

[0031] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and of course, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, any other embodiments that a person skilled in the art can obtain without inventive efforts fall within the protection scope of the present invention.

[0032] Referring to Figure 1, a roof system is shown, comprising a roof body 2 which can be configured as a flat roof or a corrugated roof. The roof shown in Figure 1 is a corrugated roof body made up of multiple arch shapes, with trough positions between adjacent arch shapes, whereas a flat roof is a roof with a horizontal top, which is commonly seen in factory buildings today. The roof body 2 is laid on roof columns 1, which are support columns necessary for erecting the roof body 2 and are already erected before the roof is constructed, which belongs to the current standard technology. A gutter system 4 is attached to the trough position of the corrugated roof or to the flat roof. For flat roofs with relatively small dimensions, gutters may be attached to the edge positions of the flat roof, but if the flat roof is relatively large, multiple gutters may be installed in the center of the roof to drain water from the flat roof.

[0033] Referring to Figure 1, a skylight system 3 is further installed in the flat roof area, ridge area or sloped roof area on the roof body 2, and the specific installation position of the skylight system 3 needs to be further determined according to the environment of the construction site and the actual usage situation, and the present application is not limited and provides several possibilities for the installation position of the skylight system 3 (as shown in Figure 1, in the case of an arched roof, the skylight system 3 may be installed in the ridge or sloped roof position, and the specific installation number and position will be determined according to the actual situation), but in the case of a flat roof, the skylight system 3 is installed as needed.

[0034] 1, 2, 3 and 4, the roof body 2 of the present application may be a metal roof or the like, but there is no limitation on the type of material used and the type may be determined according to the actual installation conditions on site. It is formed by assembling multiple sets of roof modules 21. FIG. 1 shows a diagram of three sets of roof modules 21 after they have been fully assembled, while FIG. 2 is a partial exploded view of the three sets of roof modules 21 after they have been assembled. For ease of observation, FIG. 3 is a partial exploded view of the assembled arc-shaped roof. It should be noted that the roof may be a flat roof (as shown in FIG. 2), an arc-shaped roof (as shown in FIG. 3), or an arched roof (as shown in FIG. 1). Therefore, multiple sets of roof modules 21 may be assembled to form a flat roof, an arc-shaped roof, or a combination of both. The specific number of roof modules 21 to be installed is determined according to the actual dimensions of the roof. During the assembly process, two adjacent sets of roof modules 21 are joined together by connecting plates 22, and bridge reinforcements 23 are engaged above the connecting plates 22.

[0035] Referring to FIG. 5, the roof module 21 includes a support beam 211, a lower roof shingle 212, a reinforcing assembly 213, an upper roof shingle 214, a heat insulation and moisture-proof assembly 215, a mounting bracket 216, a solar panel 217, and a self-locking assembly 218. The support beam 211 is located at the bottom and is connected to the roof column 1 to support the lower roof shingle 212 and the equipment thereon together with the roof column 1. Two or three support beams may be installed along the span direction of the lower roof shingle 212, and may be connected to or welded to the lower roof shingle 212 with bolts to ensure the stability of both. A reinforcement assembly 213 is attached to the top of the roof shingles 212, and a thermal insulation and moisture-proof assembly 215 is located between the reinforcement assemblies 213, providing thermal insulation and waterproofing for the lower roof shingles 212. A self-locking assembly 218 locks the upper roof shingle 214 above the reinforcement assembly 213, and the upper roof shingle 214 is located on top of the thermal insulation and moisture-proof assembly 215. Two sets of mounting brackets 216 arranged parallel to each other are attached to the top of the self-locking assembly 218, and solar panels 217 are attached to the top of the two sets of mounting brackets 216.

[0036] It should be noted that the thermal insulation and moisture-proof assembly 215 is composed of a moisture-proof layer, a heat-insulating layer and a waterproof layer from bottom to top, providing the lower roof board 212 with moisture-proof, heat-insulating and waterproof effects (the thermal insulation and moisture-proof assembly 24 is composed of a moisture-proof layer, a heat-insulating layer and a waterproof layer from bottom to top, similar to the structure of the waterproof reinforcement assembly 215). At the same time, the lower roof board 212 is selected to be made of color steel plate, while the upper roof board 214 is selected to be made of aluminum magnesium manganese plate as the optimal choice.

[0037] It should be noted that when assembling two adjacent sets of roof modules 21, there are two types of installation: first, joining the two adjacent sets of roof modules 21 along the span direction of the roof; and second, joining the two adjacent sets of roof modules 21 along a direction perpendicular to the span direction of the roof (shown in Figures 4 and 5). The connecting plate 22 has the same structure as the lower roof plate 212, and both have edges on both ends and a folded shape in the middle.

[0038] When joining two sets of adjacent roof modules 21 along the span direction of the roof, the two sets of lower roof panels 212 located below are joined using an upper and lower lap joint, i.e., one lower roof panel 212 is mounted on the other lower roof panel 212, which contributes to waterproofing and water conduction. A waterproof reinforcement assembly 24 is laid between two sets of reinforcement assemblies 213 located in the middle, and the two sets of upper roof panels 214 located above are connected by a connecting plate 22. When installed, both ends of the connecting plate 22 are lap jointed to the two adjacent sets of upper roof panels 214, i.e., placed above the upper roof panels 214, and the edges of both ends of the connecting plate 22 are also placed above and below, and the overlapping parts of both ends (i.e., both edges) are self-locking. The upper roof panel 214 and the connecting plate 22 are fixed by a bridge reinforcement 23 above where they are placed. The bridge reinforcement 23 has an arc shape in the middle and is bent downward at the middle, and both ends are engaged with the upper roof panel 214 or the connecting plate 22, which provides pushing force to the upper roof panel 214 and the connecting plate 22, thereby improving the anti-blow-off effect. Before installing the connecting plate 22, a waterproof reinforcement assembly 24 needs to be installed at the bottom of the connecting plate 22 and above the lower roof panel 212, thereby improving the waterproof performance between the two roof modules 21. When joining two adjacent sets of roof modules 21 along a direction perpendicular to the roof span direction, the two lower sets of lower roof panels 212 are similarly joined using an upper and lower lap joint (similar to the method of joining along the roof span direction described above), and the two central sets of reinforcing assemblies 213 are connected to ensure that the reinforcing assemblies 213 of the entire roof are ultimately connected together, and the two upper adjacent sets of upper roof panels 214 are similarly placed one above the other, and then both overlapping points are fixed by self-locking assemblies 218.

[0039] 6 and 7, the reinforcement assembly 213 includes a fastening beam 2131, a sliding bar 2132, and a sliding block 2133. The fastening beam 2131, the sliding bar 2132, and the sliding block 2133 form a frame-like structure and are located at the center of the top of the lower roof board 212. Two sets of fastening beams 2131 are provided and are laid parallel to the lower roof board 212. Each set of fastening beams 2131 is attached with a number of sliding blocks 2133, and the sliding blocks 2133 can slide back and forth on the fastening beams 2131. At the same time, the fastening beams 2131 can be selected as I-beams, which further realizes the up and down restrictions of the sliding blocks 2133 and the fastening beams 2131. In this process, corresponding sliding adjustments can be made according to the needs of the operator, but multiple sets of slide bars 2132 are similarly installed, and both ends of each slide bar 2132 are detachably connected to slide blocks 2133 on two sets of connecting beams 2131, respectively. After installation is complete, the slide bars 2132 are arranged perpendicular to the connecting beams 2131, and multiple sets of slide bars 2132 are arranged parallel to each other. It should be noted that the specific number of sets of slide blocks 2133 to be installed on each set of connecting beams 2131 is determined according to the installation conditions on site, and similarly, the specific number of sets of slide bars 2132 to be installed is also determined according to the installation conditions on site.

[0040] 6 and 7, a plurality of pairs of positioning pin holes are provided at equal distances on both sides of the fastening beam 2131, a steel groove 21333 is provided at the bottom of the slide block 2133, and the steel groove 21333 is slidably connected to the fastening beam 2131. A butterfly pin hole 21331 is further provided on the left and right sides of the slide block 2133, and the butterfly pin hole 21331 is wide at both ends and narrow in the middle. This shape has good soundness, and the butterfly pin hole 21331 and the fastening beam 2131 on the slide block 2133 are connected to each other. The positioning pin holes are locked by the butterfly pin 21332. During the assembly process, if the worker needs to adjust the distance between two adjacent slide bars 2132, he can adjust the distance between the connecting beams 2131 of the two slide blocks 2133, that is, by sliding the slide blocks 2133 on the connecting beams 2131, and after adjusting to the required position, he can lock the slide blocks 2133 and the connecting beams 2131 with the butterfly pin 21332. It should be noted that the side cross section of the fastening beam 2131 has a U-shaped structure, and fastening grooves are provided on both ends of the fastening beam 2131. The fastening grooves are one-sided grooves of the butterfly pin 21332. When joining two fastening beams 2131, the ends of the two fastening beams 2131 are both extended into the slide block 2133, and then the butterfly pin 21332 is inserted into the butterfly pin holes formed by the fastening grooves on the two fastening beams 2131, thereby securing the two fastening beams 2131 (the fastening grooves at the ends of the fastening beams 2131 can be seen in Figure 7), thereby completing the connection and fixing of two adjacent fastening beams 2131. This structure can greatly improve the stability of two adjacent fastening beams 2131 and can also connect adjacent roof panels. This is highly flexible, practical, and easy to install, and can greatly accelerate the construction speed.

[0041] 6 and 7, a sawtooth slide bar 21321 is provided on each side wall at both ends of the slide bar 2132, a groove 21336 is formed at the top of the slide block 2133, and the groove 21336 is slidably connected to the slide bar 2132, and a sawtooth pin hole 21335 is formed on each front and rear sides of the slide block 2133, and the sawtooth pin hole 21335 and the sawtooth slide bar 21321 are locked by a sawtooth pin 21334. During assembly, if the operator needs to adjust the gap between two adjacent slide blocks 2133, he can adjust the length of the slide bar 2132 between the connecting beams 2131, that is, by sliding the slide bar 2132 into the slide block 2133, and after adjusting to the required position, he can lock the slide block 2133 and the slide bar 2132 with the sawtooth pin 21334.

[0042] 9 to 13, the self-locking assembly 218 includes an outer engaging member 2181 and an inner engaging member 2182, the outer engaging member 2181 includes an inner engaging groove, the inner engaging member 2182 includes an engaging bolt that fits into the inner engaging groove, the engaging bolt is inserted into and engaged with the inner engaging groove to surround it and form an engaging groove for a bracket, and the top protrusion of the outer engaging member 2181 wraps around the inner engaging member 2182 from above, thereby realizing double-engagement self-locking, that is, the outer engaging member 2181 and the inner engaging member 2182 are internally engaged by the inner engaging groove and the engaging bolt, and the outer engaging member 2181 further wraps around the inner engaging member 2182 on the outside, thereby achieving self-locking. 12 and 13, the bracket engaging groove is formed on the inside of the outer engaging member 2181 and the inside of the inner engaging member 2182, and the fixed bracket 2183 is engaged with the bracket engaging groove formed by the two sets of engaging grooves, that is, the outer contour of the fixed bracket 2183 fits into the bracket engaging groove, and both edges of the upper roof panel 214 are restricted between the bracket engaging groove and the fixed bracket 2183. It should be noted that the bracket engaging groove is composed of two parts, upper and lower, with the upper part being a fan-shaped groove and the lower part being a rectangular groove (as shown in Figures 12 and 13).

[0043] Furthermore, when the self-locking assembly 218 and the fixing bracket 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 may be surrounded by the outside of the fixing bracket 2183, and at this time, the fixing bracket 2183 supports the upper roof panel 214 and the connecting plate 22 from the inside, and then the outer engaging member 2181 and the inner engaging member 2182 fix the upper roof panel 214, the connecting plate 22 and the fixing bracket 2183 from both sides, that is, the outer engaging member 2181 and the inner engaging 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 may be further overlapped on top of the upper roof panel 214, and then locked by the self-locking assembly 218, and in this case, it can be seen when joining two sets of adjacent roof modules, as can be seen in Figure 4.

[0044] Referring to Figure 12, the fixed bracket 2183 includes a positioning horizontal plate and a limiting vertical bar arranged perpendicular to the positioning horizontal plate. The limiting vertical bar has a wide top and narrow bottom structure, and inclined triangular brackets on both sides of its bottom are fixed to the positioning horizontal plate. The top of the limiting vertical bar is an arc-shaped protrusion, and internal recesses and protrusions are sequentially arranged downward along both sides of the arc-shaped protrusion, and this multi-stage structure is molded integrally with the limiting vertical bar.

[0045] FIG. 13 shows another embodiment of a fixing bracket 2183, which also uses a wide top and narrow bottom structure, but with a distinction at the top, and may be applied to the entire roof of the present invention.

[0046] As shown in Figure 8, the side edges of the upper roof panel 214 conform to the shape of the limiting vertical bar, and the top of the upper roof panel 214 is also an arc-shaped protrusion. Internal recesses and protrusions are sequentially provided downward along both sides of the arc-shaped protrusion, and the multi-stage structure is integrally molded with the upper roof panel 214.

[0047] Referring to FIG. 10, both sides of the solar panel 217 are fitted into the insert plates 219, and two sets of insert plates 219 are provided, which are respectively detachably mounted on the top of the two sets of mounting brackets 216. It should be noted that the outer sides of the insert plates 219 are further fixed to the openings of the mounting brackets 216 with bolts by means of L-shaped connecting plates, thereby improving the stability of the insert plate 219. By using photovoltaic power generation, energy storage, direct current, and flexibility technology and on the premise of complying with Chinese national technical standards, the solar panel is fixed to the top of the self-locking assembly 218 by an insert method, thereby realizing "energy storage" and "power supply" and changing the building's power demand from rigid to flexible.

[0048] 14, 19 and 21, when the skylight is applied to a corrugated roof, the height of each area of ​​the corrugated roof is different, it should be noted that the height of the ridge of the corrugated roof is the highest, and the negative wind pressure it receives is the largest. Therefore, in the present application, the pressure reducing assemblies 32 are installed at the four corners of the skylight 31 at the ridge, and since the negative wind pressure at the ridge is the largest, the optimal embodiment is when the pressure reducing assemblies 32 are installed at the ridge (as shown in FIG. 14), which can balance the negative wind pressure received by the skylight 31 at the ridge. When a linear sudden change occurs at the ridge, the pressure reducing assemblies 32 are suitable for use on the skylight at the ridge, and can balance the negative wind pressure received by the skylight 31. When the generated negative wind pressure exceeds the pressure set in the pressure reduction adjustment assembly 32, the pressure reduction can be achieved by the pressure reduction adjustment assembly 32; when the generated negative wind pressure is lower than the pressure set in the pressure reduction adjustment assembly 32, the skylight has already been destroyed, at this time the elastic member in the pressure reduction adjustment assembly 32 will bounce the pressure reduction device to open the pressure reduction hole and reduce the pressure, thereby ensuring that the skylight at the ridge has good supporting performance; of course, the pressure reduction adjustment assembly 32 can also be installed in the sloped roof area of ​​the corrugated roof and the skylight 31 of the flat roof (as shown in Figures 18 and 20), and the specific installation and installation position will be determined according to the actual installation situation.

[0049] Furthermore, a pressure sensor 35 is further provided inside the skylight 31, and the pressure sensor 35 can monitor the wind pressure received by the skylight 31 in real time.

[0050] 14 and 15, the pressure reducing adjustment device 32 includes a square tube 321, an elastic member 322, a pressure reducing hole 323, a support plate 324, a single plate 325, an insertion rod 326 and an outer tube 327, the top of the insertion rod 326 is connected to the square tube 321, the bottom of the outer tube 327 is fixed to the lower roof board 212, the bottom of the insertion rod 326 is slidably connected to the outer tube 327, the outer tube 327 has a pressure reducing hole 323, the top of the outer tube 327 is connected to the square tube 321 by the elastic member 322, and the top of the square tube 321 The section is fixed to the skylight 31, one end of the single panel 325 is connected to the square tube 321 by a support plate 324, and the square tube 321 is installed on the side of the skylight 31. A spacer is further installed at the contact point between the inner rod 326 and the outer tube 327, and the spacer is fixed to the inner wall of the outer tube 327 and located below the decompression hole 323. Here, the spacer may be a gasket to prevent water from entering the slit between the inner rod 326 and the outer tube 327 and affecting subsequent use. When the inner rod 326 slides upward within the outer tube 327, the decompression hole 323 is exposed, thereby realizing decompression, and when the inner rod 326 slides downward within the outer tube 327, the decompression hole 323 is covered, thereby realizing sealing.

[0051] In this way, when external negative wind pressure acts on the skylight 31 on the ridge, the skylight 31 on the ridge moves upward as a whole, and the insert rods 326 on both sides of the skylight slide upward inside the outer tube 327. When the pressure reducing holes 323 on the insert rods 326 are exposed, the pressure reducing holes 323 can reduce the pressure of the negative wind pressure in the skylight 31. The outer tube 327 is connected to the square tube 321 by the elastic members 322. When the skylight 31 moves upward due to external negative wind pressure, the skylight 31 moves as if the elastic members 322 on both sides are pulled. After the pressure reduction is completed, the skylight 31 returns to its original position due to the action of the elastic members 322. In addition, the pressure sensor 37 detects the negative wind pressure. When it is detected that the pressure exceeds the pressure set in the pressure reducing device, the elastic member 322 will operate, causing the skylight 31 to move upward as a whole, thereby reducing the pressure through the pressure reducing holes. If the resulting negative wind pressure becomes lower than the pressure set in the pressure reducing adjustment device 32, the skylight may already be broken. At this time, the elastic member 322 in the pressure reducing adjustment device 32 is manually controlled to bounce the pressure reducing device, opening the pressure reducing holes to reduce the pressure, thereby ensuring that the skylight on the ridge has good supporting performance. It should be noted that the elastic member 322 may be a general spring or damper, and the top of the single plate 325 may be fixed to the skylight 31, and the single plate 325 and the skylight 31 may be fixed together by bolts, pins or welding.

[0052] Referring to Figure 14, there are four sets of flashing boards 34, which are respectively attached to the four sides of the skylight 31. The tops of the flashing boards 34 are fixed to the outer casing 326, and there are slits between the bottoms and the lower roof board 212. The installation of the flashing boards 34 can provide a certain waterproof effect for the connection points between the skylight 31 and the lower roof board 212. At the same time, the bottoms of the four sides of the skylight 31 and the lower roof board 212 are fixed by the first infiltration prevention assemblies 33, which can further ensure the waterproof effect of the connection points between the skylight 31 and the lower roof board 212.

[0053] 16, the first anti-infiltration assembly 33 includes a folding plate 331 and a corner connector 332. The folding plate 331 is located at the bottom of the side of the skylight 31. One end of the folding plate 331 is welded to the skylight 31 and the other end is welded to the lower roof panel 212. The corner connectors 332 of two adjacent folding plates 331 are fixed at the corners of the skylight 31. The corner connectors 332 are located at the four corners of the skylight 31. That is, the four corner connectors 332 are used to connect the folding plates 331 on the four sides, thereby ensuring a tight seal between the entire skylight 31 and the lower roof panel 212.

[0054] 17 and 18, the folded plate 331 includes an integrally formed skylight weld 3311, a vertical lap joint 3312, a fold protrusion 3313, and a roof weld 3314, the skylight weld 3311 being fixed to the bottom of the side of the skylight 31, the roof weld 3314 being fixed to the lower roof panel 212, the fold protrusion 3313 and the roof weld 3314 being provided on both ends of the folded plate 331, the roof weld 3314 being for welding the roof, and the fold protrusions 3313 of two adjacent folded plates 331 are fixed by corner connecting members 332, which may be fixed by bolts or welding, etc.; the adjacent two vertical lap joints 3312 are also fixed by corner connecting members 332, and the vertical lap joints 3312 are lap-jointed to the corner connecting members 332, which may be fixed by bolts or welding, etc. The corner joint member 332 includes an upper connection portion 3321 and an arc-shaped lap joint portion 3322. The upper connection portion 3321 is located at the top of the arc-shaped lap joint portion 3322, and the upper connection portion 3321 includes two vertical welding edges. The two welding edges are welded to the bottom of the corner of the skylight 31. The arc-shaped lap joint portion 3322 connects two adjacent folded protrusions 3313 and is fixed to the folded protrusions 3313 by welding. It should be noted that the fold protrusion 3313 has an uneven fold structure, and the connection position between the arc-shaped lap joint 3322 and the fold protrusions 3313 on both sides also uses a corresponding uneven fold structure and fits snugly with the fold protrusions 3313 on both sides, thereby increasing the contact area between them and ensuring stability and waterproof effect when they are welded together, and the bottom of the arc-shaped lap joint 3322 is welded to the roof.

[0055] Referring to FIG. 19, the skylight 31 applied to a sloped roof (or a sloped roof) is based on the above and further includes a second anti-infiltration assembly 36 (shown in FIG. 19) installed at the boundary between the skylight 31 and the upslope of the sloped roof. As rainwater flows downward from the top of the ridge along the sloped roof, it tends to gather at the boundary between the skylight 31 and the upslope of the sloped roof. Therefore, by installing the second anti-infiltration assembly 36 at the boundary between the skylight 31 and the upslope of the sloped roof, it is possible to prevent the rainwater flowing from the upslope to the downslope from affecting the seal between the skylight 31 and the roof shingle, and further prevent water leakage on the roof. In this installation, the second anti-infiltration assembly 36 can achieve primary water sealing between the skylight 31 and the roof shingle, while the first anti-infiltration assembly 33 between the skylight 31 and the roof shingle achieves secondary water sealing, thereby further ensuring the seal between the skylight 31 and the roof shingle.

[0056] 20, the second infiltration prevention assembly 36 includes an infiltration prevention plate 361 and an infiltration prevention joint plate 362, one end of the infiltration prevention 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 shingle 212 by the infiltration prevention joint plate 362, the top of the infiltration prevention joint plate 362 is welded to the infiltration prevention plate 361, and the bottom of the infiltration prevention joint plate 362 is welded to the lower roof shingle 212, the infiltration prevention plate 361 has a "C"-shaped structure, with the arc-shaped opening of the "C"-shaped facing the uphill surface, such an installation arrangement makes it difficult for water to accumulate, the infiltration prevention joint plate 362 has an "S"-shaped structure, but may be set to a "C"-shape or other shapes, and the specific configuration is determined according to the actual situation on site. The "S"-shaped structure is shown in FIG. 19 of this application, and the "S"-shaped structure of this application is the optimal embodiment. An S-shaped infiltration prevention joint plate is installed between the C-shaped infiltration prevention plate and the roof. Compared with a right-angle connection member, the connection point of the S-shaped infiltration prevention joint plate has a smooth transition, reducing connection deviation caused by stress concentration. The connection points of the S-shaped infiltration prevention joint plate, the C-shaped infiltration prevention plate and the roof may be connected with rivets. Specifically, blind rivets can be selected and sealed with sealant, which reduces the connection contact area between the C-shaped infiltration prevention plate and the roof and makes the connection more reliable.

[0057] Referring to FIG. 22, when the gutter system 4 is on a flat roof, the worker can install multiple gutters on the edge of the roof or install them in the center of the roof to drain water according to actual needs. When the gutter system 4 is on a corrugated roof, the worker can install the gutters in a trough position according to actual needs. When installed in the trough position, all the rainwater collected on the roof can be discharged through the gutters 41 without affecting the roof. Specifically, the gutter 41 is installed at the eaves of the lower roof panel 212. A rainwater outlet is opened on the inner bottom wall of the gutter 41. A siphon roof drain 42 is attached to the rainwater outlet. The bottom of the rainwater outlet is connected to a rainwater pipe 49. A rainwater pipe tracing tape 46 is attached to the inside of the rainwater pipe 49 and connected to a junction box 48 attached to the inner wall of the gutter. An eave snow melting and thawing assembly 43 is installed at the upper eaves of the gutter 41 to melt and thaw snow on the roof eaves and prevent icicles formed on the eaves from falling into the gutter 41 and damaging it. A water pressure monitor 44 is installed on the side wall of the gutter 41 to detect the water pressure inside the gutter 41. A gutter snow melting and thawing assembly is installed inside the gutter 41 to melt and thaw snow inside the gutter.

[0058] 27 and 28, the siphon roof drain 42 includes a conical drain 421, a spacer 422, an inclined spiral portion 423, and a drain port 424. The conical drain 421 is provided at the top of the inclined spiral portion 423, and the spacer 422 is located outside the inclined spiral portion 423. The inclined spiral portion 423 communicates with the drain port 424 at the bottom. When installed, the inclined spiral portion 423 is connected to the piping at the rainwater outlet, and the spacer 422 fits tightly to the rainwater outlet, thereby ensuring a tight seal between the inclined spiral portion 423 and the rainwater outlet piping. When the drain port 424 is connected to the rainwater pipe 49, rainwater flows through the conical drain 421. The water flows from 421 into the inclined spiral section 423 and is discharged through the outlet 424 into the storm sewer pipe 49. The installation of the storm sewer tracing tape 46 heats the inside of the storm sewer pipe 49, thereby preventing the storm sewer pipe 49 from freezing due to low temperatures and causing blockages. It is worth noting that the threads on the outside of the inclined spiral section 423 not only ensure stability during installation, but also prevent the heat generated by the storm sewer tracing tape 46 inside the storm sewer pipe 49 from causing a temperature effect at the outlet, thereby enhancing the heat dissipation effect of the siphon roof drain 42.

[0059] Furthermore, the spacer 422 further includes an expansion layer 4221 and a honeycomb waterproof layer 4222, which are integrally molded to form an integrated spacer, with the expansion layer 4221 located on the outside of the honeycomb waterproof layer 4222. The outermost layer of the spacer 422 is the expansion layer 4221, which has the role of enhancing heat dissipation, and the heat dissipation effect increases as the thickness of the expansion layer increases. The inner layer is the honeycomb waterproof layer, and a honeycomb layer is installed at the connection with the expansion layer. If the honeycomb layer is broken, the honeycomb layer can prevent the fracture from spreading, thereby ensuring the service life of the spacer. It should be noted that the material of the expansion layer is preferably a mixture of expanded graphite, polyvinyl chloride plasticizer, polyvinyl chloride heat stabilizer, and filler.

[0060] The integral siphon roof drain spacer will now be further described.

[0061] Comparative Example 1 The total diameter of the integrated siphon roof drain spacer is 100 mm, and the diameter of the honeycomb layer is approximately 30 mm.

[0062] Example 2 The integrated siphon roof drain spacer has a total diameter of 100 mm, the outermost expanded layer has a diameter of about 10 mm, and the honeycomb layer has a diameter of about 20 mm.

[0063] Example 3 Similarly, the total diameter of the integrated siphon roof drain spacer is 100 mm, the diameter of the honeycomb layer is 18 mm, and the diameter of the outermost expanded layer is 12 mm.

[0064] Example 4 Similarly, the total diameter of the integrated siphon roof drain spacer is 100 mm, the diameter of the honeycomb layer is 16 mm, and the diameter of the outermost expanded layer is 14 mm.

[0065] Example 5 Similarly, the total diameter of the integrated siphon roof drain spacer is 100 mm, the diameter of the honeycomb layer is 14 mm, and the diameter of the outermost expanded layer is 16 mm.

[0066] Example 6 Similarly, the total diameter of the integrated siphon roof drain spacer is 100 mm, the diameter of the honeycomb layer is 12 mm, and the diameter of the outermost expanded layer is 18 mm.

[0067] Heat Dissipation Function Test Examples 1 to 5 in Table 1 are the test results of the integrated spacer. JPEG0007827861000001.jpg28170

[0068] As can be seen from Table 1, the surface temperature change of the spacers in Examples 2 to 5 was less than 5°C, but the temperature rise of Comparative Example 1, which did not add an expansion layer, was higher than 10°C. This explains why this new spacer has better heat dissipation function, and the heat dissipation function improves as the area of ​​the expansion layer increases.

[0069] 22 and 23, the eaves snow melting and ice melting assembly 43 is installed at the top of the roof and at the upper eaves position of the gutter 41. The eaves snow melting and ice melting assembly 43 includes an eaves cap 431, a heat insulating layer 432, a heat conduction pad 433, a heating cable 434 and a second water flashing board 435. The eaves cap 431 is installed at the edge of the roof, and the heat conduction pad 433 and the heat insulating layer 432 are laid sequentially at the edge of the roof. The heating cable 434 is installed on the heat conduction pad 433 and is connected to the solar panel 217 on the roof. The second water flashing board 435 is installed below the eaves cap 431, and there is a slit between the second water flashing board 435 and the lower roof board 212. Water can flow through the eaves cap 431 and out of the second water flashing board 435 without seeping into the roof and affecting the roof.

[0070] It is worth noting that the heating cable 434, i.e., electrical tracing tape, is installed on the upper eaves of the gutter, which prevents ice and snow from melting and freezing on the upper eaves of the gutter in icy and snowy weather, preventing the roof from draining water quickly in rainy and snowy weather. Furthermore, it prevents icicles and other structures from suddenly falling and damaging the inside of the gutter when they melt. At the same time, the device connects the heating cable 434 to the solar panel 217 on the roof, and a thermal conduction pad 433 is installed on the heating cable 434, and a thermal conduction pad 433 is also installed on the lower part of the heating cable 434 from the contact point to the eaves, thereby enhancing the heat generated by the heating cable 434 and its area. A heat insulating layer 432 is placed below the thermal conduction pad 433, from the eaves cap to the heating cable, to prevent the heat transferred from the thermal conduction pad 433 from causing a temperature effect that affects the underlying structure. The eaves cap 431 also prevents water from seeping into the roof. The solar panel 217 can provide energy to the heating cables 334 in the eaves snow melting and ice melting assembly 43 and the water pressure monitor 34 .

[0071] Referring to FIG. 24, the gutter snow melting and ice thawing assembly includes a gutter tracing tape 471 and a groove formed in the heat conduction plate 410, the groove having a "snake" shape, the gutter tracing tape 471 is laid in the groove in a snake-like shape, and the gutter tracing tape 471 is connected to the solar panel 217 on the roof. In this method, the tracing tape is attached to the inside of the gutter and heated to melt snow and ice.

[0072] It is worth noting that by opening a "snake-shaped" groove in the heat conduction plate and laying the gutter tracing tape 471 in the groove, the gutter tracing tape 471 also has a "snake" structure, which can increase the coverage area of ​​the tracing tape in the gutter 41, solving the problem that the area coverage rate of the electrical tracing tape generating heat on the surface of the gutter 1 is small and saving energy. The material of the heat conduction plate can preferentially be a material with higher thermal conductivity such as metal or ceramic. In this application, a relatively small amount of electrical tracing tape can generate heat evenly over a large area to cover the entire gutter 41, which can quickly melt ice and snow in icy and snowy weather. In this case, the area ratio of the "snake-shaped" heat conduction plate can be appropriately reduced and one "snake-shaped" groove can be installed inside (Figure 24 shows a schematic diagram of one groove opened in the gutter and one tracing tape laid, while Figure 23 shows the case of two grooves opened in the gutter and two tracing tapes laid). The specific number of grooves to open and the number of tracing tapes to install will be determined based on the actual dimensions of the gutter and the needs of the site. This application is not limited and only provides two embodiments. The device is intended to generate heat over a large area on the surface of the gutter with a relatively small amount of electric tracing tape, thereby achieving the effect of instantly melting ice and snow while saving energy.

[0073] 26, in another embodiment, the gutter snow melting and de-icing assembly is basically similar, but the differences are as follows: the gutter snow melting and de-icing assembly includes an intelligent spray element 472, the intelligent spray element 472 further includes a pipe 4721, a high-pressure nozzle 4722, an automatic spray control module 4723, and a snow sensor 4724, a plurality of high-pressure nozzles 4722 are provided, and are laid at equal distances on the side wall of the gutter 41, and the plurality of high-pressure nozzles 4722 are connected by the pipe 4721, it should be noted that the specific number of high-pressure nozzles 4722 to be installed is determined by the size of the gutter and the actual installation situation, and the present application is not limited thereto, the automatic spray control module 4723 and the snow sensor 4724 are provided at the end of the side wall of the gutter 41, and one end of the pipe 4721 is connected to the snow removal agent storage box The snow removal agent is salt water or snow melting agent, and the snow removal agent in the snow removal agent storage box is automatically transported into the pipe 4721 under the control of the automatic spray control module 4723, and then sprayed into the gutter by the high-pressure nozzle 4722, thereby melting the snow and ice inside the gutter. This method achieves snow and ice melting by installing a device that sprays salt water or snow melting agent inside the gutter. It should be noted here that the intelligent spray scheme here is a reinforcement based on the heat conduction plate 410, and the gutter tracing tape 471 can melt snow and ice by dissipating a large amount of heat to the heat conduction plate 410, but the salt water, snow melting agent, and other materials that are sprayed intelligently also melt the snow and ice, thereby enhancing the snow melting effect inside the gutter.

[0074] It should be noted that by installing the intelligent spray element 472, it can remove snow from the gutter in winter and cool the gutter in summer. The pipe 4721 is installed on the inner wall on both sides at a distance of 0.1 to 0.3 m from the bottom of the gutter. The specific installation height is determined according to the installation conditions on site or the actual dimensions of the gutter. This application is not limited to this and only provides a suitable range for reference. The snow sensor 4724 and the automatic spray system 4723 are simultaneously connected to the pipe 4721 of this application. The snow sensor 4724 can sense the amount of snowfall and the temperature. When it snows in winter, or when the temperature is below 0°C, the snow sensor 4724 can sense the amount of snowfall and the temperature. When 24 receives a signal, it controls the automatic spray control module to spray snow removal agent, etc., and can also control the amount of water sprayed based on the amount of snowfall. In particular, when there is a sudden snowfall in the middle of the night, the system will operate immediately to prevent snow from freezing inside the gutter. In hot summer weather, the automatic spray system 4723 can be set to control the spraying of fresh water to cool down the components within a certain temperature range, thereby protecting the components and extending their service life. This device melts snow and ice in the gutter without causing temperature differences on the metal roof, effectively preventing water leakage at the joints of the metal roof due to temperature effects and making the roof unstable.

[0075] A roof equipment box is installed inside the roof, and the inside of the roof equipment box contains, connected in order from top to bottom, an inverter, an energy storage module, a load, a water pressure signal transmission module and a heating control module. The inverter is connected to the solar panels 217 and converts the DC current generated by the solar panels 217 into AC current. The energy storage module stores the electrical energy converted and formed by the inverter and transports the electrical energy to the power consuming load. The heating control module controls the operating state, heating time and adjusted temperature of the electrical tracing tape at each location. The water pressure signal transmission module is connected to the water pressure monitor 44 and transmits the water pressure value in the gutter detected by the water pressure monitor 44. If it is detected that the water pressure value in the gutter is abnormal, inspection and maintenance should be carried out immediately.

[0076] The specific mounting principle of the roof body of the present application is as follows. Before assembly, first, before assembling the metal roof, an assembly platform must be erected on the ground in the span direction of the factory building, and the height of the assembly platform must reach the height of the roof columns 1 and meet the load requirements. In addition, temporary assembly slide rails must be installed on the roof columns and beams of the factory building. Second, the steel structure factory building must be arranged and assembled in sections. For structures with relatively large spans, multiple roof panels must be fixed to the assembly platform and then the entire structure must be slide-mounted. Third, bolt holes must be installed on the roof column beams to facilitate sliding and bolting the roof modules to the designated positions.

[0077] It should be noted that the bottom of the assembly platform is supported by a number of support columns, and the top of the platform may be slightly lower than the height of the roof column; during installation, workers can transport the parts to the platform and then assemble them directly above the assembly platform, thereby facilitating the entire module to be erected on the roof column; the assembly platform is not the scheme protected by the present application, and the assembly platform is more common in current construction sites, so the present application will only briefly describe it here.

[0078] Regarding the method of assembling a single roof module of the present application, During assembly, the roof module 21 preforms are transported from the factory to the site, and a single roof module 21 is assembled on the assembly platform. First, the lower roof panel 212 is attached to the top of the support beam 211, and a slide shoe is attached to the bottom of the support beam 211, so that the slide shoe can slide on the slide rail. Next, the fastening beam 2131, slide block 2133, and slide bar 2132 are placed above the lower roof panel 212 and locked together. After that, the self-locking assembly 218 is attached above the slide bar 2132, and the self-locking assembly 218 is used to fix the upper roof panel 214. In each gap between the fastening beam 2131 and the slide bar 2132, the thermal insulation and moisture barrier layers 215 are placed. From bottom to top, the thermal insulation and moisture barrier layers 215 are a moisture barrier layer, a thermal insulation layer, and a waterproof layer. Finally, the self-locking assembly 218 is placed above the self-locking assembly 218. After the solar panels 217 are installed, the single roof module 21, once assembled, is slid to the designated position on the roof using the slide rails on the roof pillars. The roof module is then lifted up with a jack, and the jack lifts up the upper support beam 211, allowing the entire module to be slowly placed on the roof pillar and then secured in place. The slide shoes and corresponding slide rails are then removed, and the roof module 21 is then fixed and connected to the roof pillar 1. It should be noted that if the span between the roof pillars is extremely large, a temporary steel pillar can be installed in the middle of the span. The height of the temporary steel pillar is the same as that of the left and right roof pillars, and slide rails are also installed on the temporary pillar. The sliding steps are similar to those described above. After the roofs of both units have slid simultaneously to the designated position, the bottom support beams 11 on both sides are connected with bolts, and some of the slide rails are then removed with a jack. Next, a waterproof reinforcement assembly 24 is laid at the connection point between two adjacent roof modules 21, and a connecting plate 22 is used above the waterproof reinforcement assembly 24 to connect the two roof modules 21. During assembly, attention must be paid to the dimensional arrangement and the offset lap joints of the front and rear roof panels. If the span of the factory building is too large, multiple modules must be installed and then the entire building must be slide-installed, and the load stability of the assembly platform must be checked. If the span of the factory building is too large, the temporary steel columns described above can be used for assistance. For the steps, refer to the description of the temporary steel columns above. The above steps are carried out in order to assemble the entire roof block by block, and then slide it to the specified position. The fine adjustment system between the fastening beams 2131, sliding bars 2132 and sliding blocks 2133 in the roof system itself can be used to fine-tune the roof, thereby achieving the overall roof effect.

[0079] During the assembly process of the roof body 2, workers must also install and arrange the skylight system 3 and gutter system 4 as needed, and the specific installation positions and number are determined by the site conditions and the dimensions and shape of the roof body 2, etc.

[0080] When the skylight system 3 is used after installation, when it is used in rainy and gloomy weather and external negative wind pressure acts on the roof, different wind pressures will be generated at different points on the roof, with the negative wind pressure being the greatest at the ridge. As a result, the skylights 31 installed on the ridge will also be subjected to the greatest negative wind pressure, causing them to move upwards. If the negative wind pressure is strong, the skylights 31 may even be shattered. The corresponding negative wind pressure is the negative wind pressure on the sloped surface, which, although experiencing less negative wind pressure than the ridge, is still affected by the negative wind pressure. Therefore, pressure reducing devices are installed at all three skylights 31 in the flat room, the sloped room and the ridge.

[0081] When external negative wind pressure acts on the skylight 31 on the ridge, it moves the entire skylight 31 on the ridge upward, and the insert rods 326 on both sides of the skylight slide upward inside the outer casing 327. When the pressure reducing holes 323 on the insert rods 326 are exposed, the pressure reducing holes 323 can reduce the pressure of the negative wind pressure in the skylight 31. The outer casing 327 is connected to the square tube 321 by the elastic member 322. When the skylight 31 moves upward due to external negative wind pressure, the skylight 31 moves as if the elastic members 322 on both sides are pulled, and the pressure reduction is completed. After that, it will return to its original position due to the action of the elastic member 322, and when the pressure sensor 37 detects that the negative wind pressure exceeds the pressure set in the pressure reducing device, the elastic member 322 will operate to move the skylight 31 upward as a whole, reducing the pressure through the pressure reducing hole; when the generated negative wind pressure becomes lower than the pressure set in the pressure reducing adjustment device 32, the skylight may already be broken; at this time, the elastic member 322 in the pressure reducing adjustment device 32 is manually controlled to bounce the pressure reducing device, open the pressure reducing hole and reduce the pressure, thereby ensuring that the skylight on the ridge has good supporting performance.

[0082] In addition, since it is necessary to ensure an excellent sealing effect at the connection points between the four sides of the skylight 31 and the lower roof panel 212, a first infiltration prevention assembly 33 is installed at the connection points between the two, and the engagement between the folded plate 331 and the corner joint member 332 realizes sealing at the connection points between the entire skylight 31 and the lower roof panel 212. In addition, the installation of the folded protrusion 3313 on the folded plate 331 can prevent rainwater from passing through the folded protrusion 3313, and the folded protrusion 3313 provides multiple rainwater blocking. This ensures a tight seal at the connection point between the skylight 31 and the lower roof panel, and the first drip-proof board 34 can receive rainwater from above that hits the connection point between the skylight 31 and the lower roof panel 212. When the rainwater falls onto the first drip-proof board 34, it provides a certain amount of shock absorption and then slides down from the first drip-proof board 34 to the roof. It should be noted that the first seepage prevention assembly 33 is installed at all three skylights: in the flat room, the sloped room and the ridge.

[0083] Furthermore, on slopes, especially uphill slopes, rainwater slides down the slope from the highest ridge, so the seal between the skylight 31 and the lower roof panel on the uphill surface needs to be further fixed to prevent seepage. Therefore, a second seepage prevention assembly 36 is added below the first flashing board 34 on the uphill surface, and a second seepage prevention assembly 36 is added to the tip of the first seepage prevention assembly 33. In other words, the seepage prevention board 361 and the seepage prevention joint board 362 can block rainwater the first time, and then the first seepage prevention assembly 33 blocks rainwater the second time, thereby further ensuring the sealing effect between the skylight 31 and the lower roof panel on the uphill surface.

[0084] When the gutter system 4 is installed and put into use, in rainy and snowy weather, rain and snow will flow from the roof into the gutter 41 at the eaves of the roof. Because the gutter 41 is concave and there is a certain height between its interior and the eaves of the gutter, icicles may form on the upper eaves in rainy and snowy weather. Therefore, the eaves snow melting and thawing assembly 43 is installed to remove the icicles. During the removal process, the installation of the heating cable 434 and the heat conduction pad 433 enables snow melting and thawing at high temperatures, and the melted rainwater can flow from the second dripping plate 435 into the gutter 41 through the action of the eaves cap 431, thereby preventing icicles from forming on the upper eaves of the gutter.

[0085] Furthermore, rainwater that falls into the gutter 41 runs the risk of freezing due to the low temperature outside, and snow that falls into the gutter may accumulate, but because the gutter is located at a high altitude, it is difficult to remove manually. Therefore, a gutter snow melting and thawing assembly is installed inside the gutter 41 to melt and thaw the snow inside the gutter 41. Specifically, there are two options for this process: the first is to install tracing tape inside the gutter to melt and thaw the snow, and the second is to install a device for spraying snow-melting agent on the inner wall of the gutter to melt and thaw the snow.

[0086] When selectively using tracing tape to melt snow and ice in the gutter, one or two gutter tracing tapes 471 are selected and used according to the dimensions of the gutter 41 and the actual conditions on site. In rainy and snowy weather, the activation of the gutter tracing tape 471 is controlled by the heating control module in the indoor roof equipment box, and the gutter tracing tape 471 heats the inside of the gutter 41, thereby melting and thawing the snow or ice inside the gutter. After the snow and ice melt into rainwater, it can drop down through the siphon roof drain 42. When the snow and ice enters the siphon roof drain 42, the storm sewer pipe tracing tape 46 in the storm sewer pipe 49 also starts to operate. The storm sewer pipe tracing tape 46 is also controlled by the roof equipment box. The storm sewer pipe tracing tape 46 can prevent the rainwater from freezing in the storm sewer pipe 49 in a low-temperature environment, and finally it passes through the storm sewer pipe 49 and drops to the ground. Energy is supplied to the storm sewer pipe tracing tape 46 and the gutter tracing tape 471 by the solar panel 217.

[0087] When selecting and using the method of spraying snow-melting agent to melt snow and ice, high-pressure nozzles 4722 can be installed inside the gutter 41 according to the dimensions of the gutter 41 and the actual situation on site, and multiple high-pressure nozzles 4722 can be connected to a pipe 4721 and connected to an automatic spray control module and a snow sensor 4724. The inlet of the pipe 4721 is connected to an external snow-melting agent storage box, and when in use, the roof equipment box controls the operation of the automatic spray control module 4723, which imports the snow-melting agent from the snow-melting agent storage box into the pipe 4721, and then sprays it into the gutter 41 from the multiple high-pressure nozzles 4722 to remove snow. The rainwater is controlled to act on the ice or snow inside, thereby realizing the snow melting and thawing process. After the snow and ice melt into rainwater, it can fall through the siphon roof drain 42. When the snow and ice melt into rainwater, the rainwater tracing tape 46 inside the rainwater pipe 49 also starts to operate. The rainwater tracing tape 46 is also controlled by the roof equipment box. The rainwater tracing tape 46 can prevent the rainwater from freezing inside the rainwater pipe 49 in a low-temperature environment, and finally it can fall through the rainwater pipe 49 to the ground. Energy is supplied to the rainwater tracing tape 46, automatic spray control module 4723, and snowfall sensor 4724 by the solar panel 217.
