Description

Technical Field

[0001] The present invention relates to the technical field of roofs, and specifically to a roof system.

Background Art

[0002] In recent years, roof structures have been widely applied to large-span architectural structures such as railway stations, airports, and factory buildings for scientific research because of their advantages of light weight, high heat preservation effect, and fast construction speed. Generally, in large-scale steel structure roof projects, the purpose is to reduce the overlapping of roof plates, improve the integrity of the roof, and ensure the waterproof function and overall pressure resistance function of the roof. Moreover, corrugated metal roof plates have the advantages of light self-weight, beautiful appearance, and easy and rapid construction, so large-span metal roof plates are widely used. However, there are many problems from the perspective of the prior art.

[0003] In terms of the construction quality of the roof, when installing the entire roof panel, the connection points are not firmly connected and are prone to deformation. In addition, since the connection method between the members of the roof panel generally uses mechanical connections in the form of locking, meshing, or tightening, the connection rigidity is low. When subjected to strong wind loads or normal wind loads at specific wind vibration frequencies, a blow-off accident may occur. For example, in the existing patent document with the registration number CN218176365 and the patent name "Reinforcing engagement structure of metal roof panels", specifically, "a ridge cover and a ridge connection member are provided, and an elastic traction device for gathering the side plates on both sides of the ridge cover is attached inside the ridge cover. The ridge cover of the present invention gathers the side plates on both sides of the ridge cover inward by the traction of the elastic traction device inside it, and engages with the buckle of the ridge cover, thereby strengthening the connection strength between the ridge cover and the ridge connection member and reducing the risk of the ridge cover being blown off by strong wind" is disclosed. Although the above technology can improve the blow-off prevention function of the metal roof panel to a certain extent, it always uses the multi-point arrangement form, is densely arranged, and each point acts independently, so the fixing points cannot cooperate to bear the force, resulting in low stability and a risk of falling off in extreme cases. At the same time, it can be installed safely and easily on the roof. Currently, when installing the roof panel, it generally requires high-altitude work to complete the overall laying at the high place of the roof. However, during the high-altitude work process, construction workers often encounter potential safety problems, with low safety, and it is also difficult to control the accuracy during the construction process at high altitudes.

[0004] As an important part of the roof, the skylight's wind resistance and penetration prevention functions are particularly important. The surface wind pressure characteristic distribution of the roof cover is mainly affected by the turbulent flow, which is a characteristic of the structure itself. At the highest point of the roof, the air flow separates, resulting in a relatively large negative pressure. Perform relevant simulations 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 pitched roofs, the force-bearing state of the skylight on the ridge is complex. Due to the negative wind pressure effect, the stability of the skylight at this location is relatively likely to be low, and it is more difficult to resist the influence of stronger wind loads, resulting in problems such as deformation and penetration.

[0005] However, currently, there is no wind pressure reduction treatment for the wind pressure generally received by the roof in the market. Most of them add a reinforcement structure to the building. Specifically, in the existing patent document with the registration number CN214169604U and the patent name "Wind and snow resistant building structure for metal roofs", "Building caps are respectively fixed on the upper layer metal rolled steel plates of two opposite roofs. The shape of the building cap fits the shape of the trough of the upper layer metal rolled steel plate of the roof. The building cap is connected to the peak of the upper surface of the upper layer metal rolled steel plate of the roof. The building cap is connected and fixed to the trough of the upper surface of the upper layer metal rolled steel plate of the roof. Butyl tapes with the tips facing the ends are installed at the joints, and a gap is installed between the two butyl tapes. By using a custom-shaped building cap and a metal exterior building tile, a special butyl tape laying method and a unique connection method, the building structure of the entire metal roof can be made stronger, and the problems of slight wind leakage and snow leakage can be effectively solved." are disclosed. However, when facing a storm or heavy snowstorm weather, it is difficult to resist the action of wind load, and the skylight in the building will be deformed.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The technical problem to be solved by the present invention is how to solve the problems that the current construction quality and construction safety of the roof are low, and the skylight of the roof is easily deformed under the influence of wind pressure.

Means for Solving the Problems

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions. A roof system, comprising a roof body capable of forming a flat roof or a corrugated roof, the roof body is laid on roof columns, a gutter system is attached to the trough position of the corrugated roof or the flat roof, a skylight system is further attached to the inclined roof, building, or flat roof of the corrugated roof, and a pressure reduction adjustment assembly is installed in the skylight system. The roof body is formed by assembling a plurality of sets of roof modules. Two adjacent sets of roof modules along the span direction of the roof are joined by a connecting plate, and both ends of the connecting plate are overlapped and joined to the two adjacent sets of roof modules, and the two are fixed by a self-locking assembly. Two adjacent sets of roof modules along the direction perpendicular to the span direction of the roof are also fixed by a self-locking assembly. The present invention assembles a plurality of sets of roof modules into a roof body, and fixes them when assembling two adjacent roof modules by using a connecting plate and a self-locking assembly, thereby further ensuring the soundness of the metal roof formwork and the entire roof. Multiple reinforcement points cooperate to operate, with high utilization rate, ensuring the soundness and support function of the entire roof. At the same time, the means of prefabricating the modules independently and then joining them can be operated flexibly, is easy to install, and can further accelerate the construction progress, ensuring the safety of the constructor. However, the installation of the self-locking assembly can solve the problems of poor performance, mounting accuracy, and construction safety in preventing the roof panel from being blown off due to its inherent form. The entire roof system ensures the wind resistance performance through the coordinated action of the brackets and various types of reinforcement members. At the same time, a pressure reduction adjustment assembly is installed in the skylight. Since the support force caused by a stronger wind load is too large, the pressure reduction adjustment assembly can effectively respond to the problem of the building being deformed. When the generated negative wind pressure exceeds the set pressure, the pressure reduction adjustment assembly performs pressure reduction, thereby ensuring that the skylight of the roof has good support performance.

Advantages of the Invention

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows. First of all, the present invention assembles a plurality of sets of roof modules into the roof body and fixes them when assembling two adjacent roof modules by using a connecting plate and a self-locking assembly, thereby further ensuring the soundness of the metal roof formwork and the entire roof. Multiple reinforcement points cooperate to operate, with high utilization rate, ensuring the soundness and support function of the entire roof. At the same time, the means of prefabricating the modules independently and then joining them can be operated flexibly, is easy to install, and can further accelerate the construction progress, ensuring the safety of the constructor. However, the installation of the self-locking assembly can solve the problems of poor performance in preventing the roof panel from being blown off due to its inherent form, mounting accuracy, and construction safety. The entire roof system ensures its wind resistance performance through the coordinated action of brackets and various types of reinforcement members. At the same time, a pressure relief adjustment assembly is installed on the skylight. Since the support force caused by stronger wind loads is too large, the pressure relief adjustment assembly can effectively respond to the problem of the building being deformed. When the generated negative wind pressure exceeds the set pressure, the pressure relief adjustment assembly performs pressure relief, thereby ensuring that the skylight of the roof has good support performance. Second, the present invention locks both sides of two adjacent lower roof panels by installing a self-locking assembly, enabling the outer engaging member to cover the inner engaging member from the outside. The protrusion of the inner engaging member engages with the outer engaging member to ensure self-locking between the inner and outer engaging members. A fixing bracket is further provided inside the inner and outer engaging members. In this way, the fixing bracket can protrude and support the bottoms on both sides of the lower roof panel. By locking the lower roof panel from the outside by the inner and outer engaging members, the soundness during the installation of the lower roof panel is ensured, the wind resistance of the lower roof panel 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. The side edge of the roof panel also has a structure that is wider at the top and narrower at the bottom. By engaging with each other, they can effectively resist the negative pressure effect caused by wind load (i.e., resist the pulling resistance). At the same time, by installing an inclined triangular bracket at the small cross-section location at the lower part of the fixing bracket, the pressure resistance effect of the bracket is effectively ensured, and the lower roof panel can be reinforced before the lower roof panel is damaged, thereby solving the problems of weak performance in preventing the roof panel from being blown off due to its inherent form, as well as low installation accuracy and construction safety. The overall metal roof system ensures its wind resistance performance through the coordinated action of the bracket and various types of reinforcing members, greatly improving the structural strength, rigidity, and wind resistance performance of the roof panel. Third, a plurality of sets of positioning pin holes are opened at equal distances on both sides of the fastening beam. The slide block can slide on the fastening beam, and butterfly pin holes corresponding to the positioning pin holes are opened on the slide block. Therefore, the fixation between the fastening beam and the slide block can be realized by the butterfly pin. The operator can move and adjust the slide block by controlling the installation of the butterfly pin, realize the relative movement above the fastening beam of the upper roof panel, and further realize the connection between adjacent roof panels. It has high flexibility, high practicality, is easy to install, and can greatly accelerate the construction speed. Fourthly, in the present invention, the top of the slide block can be slidably connected to the slide bar. However, a serrated pin hole is opened in the slide block, and a serrated slide bar corresponding to the slide bar is installed. In this way, the serrated pin can pass through the serrated pin hole and engage with the serrated slide bar, thereby realizing the locking between the slide block and the slide bar, and further realizing fine adjustment with respect to the slide bar to avoid the problem that the slide block and the slide bar are locked. The position can be easily adjusted, that is, by adjusting the distance between the two fastening beams for different lower roof plates, it can be applied to lower roof plates of different dimensions, ensuring efficient connection of subsequent roof plates, with high flexibility, high practicability, easy installation, and can significantly accelerate the construction speed. Fifthly, in the present invention, a heat preservation and moisture prevention assembly is placed in each gap between the fastening beam and the slide bar. The heat preservation and moisture prevention assembly is, in order from top to bottom, a moisture prevention layer, a heat preservation layer, and a waterproof layer. The fastening beam, the slide bar, and the fixing bracket can play a supporting role with respect to the upper roof plate, and the heat preservation and moisture prevention assembly is not directly subjected to pressure, thereby ensuring the structural stability. When external pressure is received, the pressure is mainly received by the bracket and the reinforcement assembly, improving the integrity. Sixthly, in the present application, a slidable sleeve decompression assembly is installed at the four corner positions of the skylight. Since the support force of the sleeve decompression assembly due to stronger wind loads is too large, it can effectively respond to the problem that the building deforms. At the same time, a decompression hole is provided in the outer sleeve, an elastic member is introduced, and it cooperates with a pressure sensor. When the generated negative wind pressure exceeds the pressure set in the decompression device, the decompression adjustment device starts decompression. When the decompression is completed, the elastic member plays a pulling-back role and immediately closes the decompression adjustment device. When the generated negative wind pressure is lower than the pressure set in the decompression device, there is a risk that the skylight has already been damaged. At this time, the elastic member bounces the decompression device and opens the decompression adjustment device to perform decompression, thereby ensuring that the skylight in the building has good support performance. As the seventh aspect, in the present application, the overall joint is made by a horizontal folding plate at the joint between the four sides of the skylight and the roof. The installation of the horizontal folding plate greatly increases the contact area at the joint, making the contact more reliable. At the same time, the horizontal fold extends the water intrusion path at the joint between the skylight and the roof, and can immediately discharge the fast water flow in heavy rain and heavy snow weather, thereby effectively improving the waterproof performance at the joint between the lower opening of the skylight and the metal roof panel. As the eighth aspect, in the present invention, a C-shaped penetration prevention plate is provided at the boundary between the skylight and the upward slope of the inclined roof. In cooperation with the drain plate, by moving the point where penetration is likely upward, the penetration phenomenon caused by rainwater accumulating at the joint between the skylight and the upward slope of the roof in heavy rain and heavy snow weather conditions is effectively solved. An S-shaped joint plate for penetration prevention is installed between the C-shaped penetration prevention plate and the roof. The installation of the S-shaped joint plate for penetration prevention enables the connection location to transition smoothly, reducing the connection displacement due to stress concentration. Moreover, the connection locations of the C-shaped penetration prevention plate, the S-shaped joint plate for penetration prevention, and the roof are connected by rivets and sealed with a sealing material, thereby reducing the contact area where the C-shaped penetration prevention plate is connected to the roof and making the connection more reliable. As the ninth aspect, in the present invention, a roof snow melting and deicing assembly is installed on the upper eaves of the gutter, and a gutter snow melting and deicing assembly is further provided inside the gutter. The solar panel can supply electrical energy to the two snow melting and deicing assemblies to realize snow melting and deicing on the upper eaves of the gutter and inside the gutter. At the same time, a siphon roof drain is provided at the rainwater inlet in the gutter, a rainwater pipe trace tape is provided in the siphon roof drain, and a spacer is attached to the siphon roof drain. Thereby, the drainage bucket of the siphon drain gutter undergoes thermal expansion and contraction due to the temperature effect, and further causes the phenomenon that the siphon roof drain separates from the bottom of the gutter, resulting in a penetration problem. In the present invention, when the shape such as an "icicle" formed by icing in winter on the upper eaves of the gutter melts and suddenly falls, the gutter structure is damaged to a certain extent, and further water leakage occurs in the gutter. This problem is avoided, ensuring that the gutter realizes all-round snow melting and deicing treatment. At the same time, the snow melting cover area of the gutter is small, the snow melting effect is not obvious, and the problem of energy saving is solved. As for the 10th, a heat conduction plate with "snake-shaped" concave grooves is installed on the surface of the gutter body, and an electrical trace tape is laid in the "snake-shaped" concave grooves of the heat conduction plate, thereby increasing the cover area of the trace tape in the gutter. It solves the problem that the area coverage rate of the electrical trace tape generating heat on the surface of the gutter is small and energy is saved. The material of the heat conduction plate may preferably be a material with higher thermal conductivity such as metal or ceramic. With less electrical trace tape, large-area heat is generated uniformly to cover the entire gutter, and the ice and snow melt immediately in the ice and snow weather. If the area of the gutter is smaller, the area ratio of the "snake-shaped" concave groove to the heat conduction plate can be appropriately reduced, and one "snake-shaped" concave groove can be installed inside. This device is intended to generate large-area heat on the surface of the gutter with less electrical trace tape and achieve the effect of immediately melting ice and snow based on energy conservation. As for the 11th, an intelligent spray member is installed on the inner wall of the gutter, so that snow in the gutter can be removed in winter and the function of cooling the inside of the gutter can be achieved in summer. The intelligent spray member is composed of a pipe, a high-pressure nozzle, a snowfall sensor and an automatic spray control module. The pipe is attached to the inner walls on both sides 0.1 - 0.3 m away from the bottom of the gutter. A plurality of high-pressure nozzles are designed and attached to the pipe, and the high-pressure nozzles are evenly arranged on the inner wall of the gutter at intervals. A snowfall sensor and an automatic spray system are simultaneously connected to the pipe. The snowfall sensor can sense the snowfall amount and temperature. When it snows in winter and the temperature is below 0°C, when the snowfall sensor receives a signal, the automatic spray control module controls the spraying of a snow removal substance (the snow removal substance may be brine or a snow melting agent, etc.), and the spraying amount can be further controlled based on the snowfall amount. Especially when it suddenly snows at night, the system operates immediately to prevent the snow from freezing in the gutter. In summer, in hot weather, the automatic spray system may be set to spray clean water within a certain temperature range to cool down and protect the members, and the service life can be extended.

Mode for Carrying Out the Invention

[0031] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 obtained by those skilled in the art without creative labor shall fall within the protection scope of the present invention.

[0032] Referring to FIG. 1, there is provided a roof system comprising a roof body 2 capable of forming a flat roof or a corrugated roof. The roof shown in FIG. 1 is a corrugated roof body composed of a plurality of arch shapes, and the space between adjacent arch shapes is a trough position. A flat roof is a roof with a horizontal rooftop, which is commonly seen in current factory buildings. The roof body 2 is laid on roof columns 1. The roof columns 1 are support columns necessary for building the roof body 2 and have been built before constructing the roof, belonging to the current normal technology. A gutter system 4 is attached to the trough position of the corrugated roof or the flat roof. For a flat roof with a relatively small size, the gutter may be attached to the edge position of the flat roof. However, when the size of the flat roof is relatively large, a plurality of gutters for draining water from the flat roof may be installed at the center of the roof.

[0033] Referring to FIG. 1, a skylight system 3 is further attached to the flat roof area, or the ridge area, or the pitched roof area on the roof body 2. 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 thereto. Some possibilities of the installation position of the skylight system 3 are provided (as shown in FIG. 1, in the case of an arch-shaped roof, the skylight system 3 may be installed at the ridge or the pitched roof position, and the specific number and position of the installation are determined according to the actual situation). However, in the case of a flat roof, the skylight system 3 is installed as required.

[0034] Referring to FIGS. 1, 2, 3 and 4, the roof body 2 of the present application may be a metal roof or the like, and there is no limitation on what kind of material here, and it may be determined according to the actual installation situation on site. It is assembled by a plurality of sets of roof modules 21. FIG. 1 shows the shape after completely assembling three sets of roof modules 21. FIG. 2 is a partial exploded view after assembling three sets of roof modules 21. For easy observation, FIG. 3 is a partial exploded view after assembling an arc-shaped roof. It should be noted that the roof may be a flat roof (shown in FIG. 2) or an arc-shaped roof (shown in FIG. 3) or an arch-shaped roof (shown in FIG. 1). Therefore, a plurality of sets of roof modules 21 may be assembled into a flat roof or an arc-shaped roof or a roof combining both. Specifically, how many sets of roof modules 21 need to be installed is determined by the actual size of the roof. During the assembly process, two adjacent sets of roof modules 21 are joined by a connection plate 22, and a bridge reinforcing member 23 is engaged above the connection plate 22.

[0035] Referring to FIG. 5, the roof module 21 includes a support beam 211, a lower roof plate 212, a reinforcing assembly 213, an upper roof plate 214, a heat and moisture insulation assembly 215, a mounting bracket 216, a solar panel 217 and a self-locking assembly 218. The support beam 211 is located at the lowermost position and is connected to the roof column 1 to support the lower roof plate 212 and the equipment thereon together with the roof column 1. Two to three support beams 211 may be laid along the span direction of the lower roof plate 212, and the stability of both can be ensured by connecting or welding the lower roof plate 212 with bolts. A reinforcing assembly 213 is attached to the top of the lower roof plate 212. The heat and moisture insulation assembly 215 is located between the reinforcing assemblies 213 and can perform a heat and waterproofing function for the lower roof plate 212. Above the reinforcing assembly 213, the upper roof plate 214 is locked by the self-locking assembly 218. The upper roof plate 214 is located at the top of the heat and moisture insulation assembly 215. Two sets of mounting brackets 216 arranged in parallel are attached to the top of the self-locking assembly 218, and a solar panel 217 is attached to the top of the two sets of mounting brackets 216.

[0036] It should be noted that the heat preservation and moisture-proof assembly 215 consists of a moisture-proof layer, a heat preservation layer and a waterproof layer in sequence from bottom to top, providing the effects of moisture-proof, heat preservation and waterproof for the lower roof board 212. (The heat preservation and moisture-proof assembly 24 has the same structure as the waterproof reinforcement assembly 215, consisting of a moisture-proof layer, a heat preservation layer and a waterproof layer in sequence from bottom to top.) At the same time, the lower roof board 212 selects a color steel plate, while the upper roof board 214 selects an aluminum magnesium manganese plate as the optimal option.

[0037] It should be noted that when assembling two adjacent sets of roof modules 21, there are two types of installations. Firstly, join two adjacent sets of roof modules 21 along the span direction of the roof. Secondly, join 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 connection plate 22 has the same structure as the lower roof board 212. Both have edges installed at both ends and are corrugated in the middle.

[0038] When two adjacent sets of roof modules 21 are joined along the span direction of the roof, the two sets of lower roof panels 212 located at the bottom 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 transmission. A waterproof reinforcement assembly 24 is laid between two sets of reinforcement assemblies 213 located in the middle, and two sets of upper roof panels 214 located at the top are connected by a connecting plate 22. During installation, both ends of the connecting plate 22 are lap jointed to the two adjacent sets of upper roof panels 214, i.e., overlapped above the upper roof panels 214, and the edges of both ends of the connecting plate 22 are also overlapped up and down, 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 the bridge reinforcement 23, and the bridge reinforcement 23 is arc-shaped in the center, and the central part is bent downward, and both ends are engaged with the upper roof panel 214 or the connecting plate 22, so that the upper roof panel 214 and the connecting plate 22 can be pushed out with a pushing force to better prevent blowing away; before the connecting plate 22 is installed, a waterproof reinforcement assembly 24 needs to be laid at the bottom of the connecting plate 22 and above the lower roof panel 212, which improves the waterproof performance between the two roof modules 21; When joining two adjacent sets of roof modules 21 along a direction perpendicular to the span direction of the roof, 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 span direction of the roof 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 finally connected together, and the two adjacent upper sets of upper roof panels 214 are similarly joined using an upper and lower overlap method, and then both of the two overlapping points are fixed by self-locking assemblies 218.

[0039] Referring to FIGS. 6 and 7, the reinforcement assembly 213 includes a fastening beam 2131, a slide bar 2132 and a slide block 2133. The fastening beam 2131, the slide bar 2132 and the slide block 2133 form a frame structure and are located at the central position of the top of the lower roof plate 212. Two sets of fastening beams 2131 are provided and laid parallel to the lower roof plate 212. A plurality of slide blocks 2133 are attached to each set of fastening beams 2131, and the slide blocks 2133 can slide back and forth on the fastening beam 2131. At the same time, the fastening beam 2131 may select an I-beam. Furthermore, the upper and lower limits of the slide block 2133 and the fastening beam 2131 can be realized. This process may perform corresponding sliding adjustments according to the needs of the operator. Similarly, a plurality of sets of slide bars 2132 are installed, and both ends of each slide bar 2132 are removably connected to the slide blocks 2133 on two sets of fastening beams 2131 respectively. After the installation is completed, the slide bar 2132 is arranged perpendicular to the fastening beam 2131, and a plurality of 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 installed on each set of fastening beams 2131 is determined by the on-site installation situation. Similarly, the specific number of sets of slide bars 2132 installed is also determined by the on-site installation situation.

[0040] Furthermore, referring to FIGS. 6 and 7, a plurality of sets of positioning pin holes are opened at equal distances on both sides of the fastening beam 2131. A steel groove 21333 is opened at the bottom of the slide block 2133, and the steel groove 21333 is slidably connected to the fastening beam 2131. Butterfly pin holes 21331 are further opened on both the left and right sides of the slide block 2133. The butterfly pin holes 21331 have a structure with wide ends and a narrow middle. Such a shape has good soundness. The butterfly pin holes 21331 and the positioning pin holes on the fastening beam 2131 are locked by the butterfly pins 21332. During the assembly process, when an operator needs to adjust the distance between two adjacent slide bars 2132, the operator can adjust the distance between the two slide blocks 2133 on the fastening beam 2131, that is, the adjustment can be performed by sliding the slide block 2133 on the fastening beam 2131. After adjusting to the required position, the slide block 2133 and the fastening beam 2131 can be locked with the butterfly pin 21332. It should be noted that the cross-section of the fastening beam 2131 presents an I-shaped structure, and fastening grooves are opened at both ends of the fastening beam 2131. The fastening grooves are one-sided grooves of the butterfly pins 21332. When joining two fastening beams 2131, the ends of both fastening beams 2131 extend into the slide block 2133. Then, if the butterfly pins 21332 are inserted into the butterfly pin holes formed by the fastening grooves on the two fastening beams 2131, the fixation of the two fastening beams 2131 can be realized (the fastening grooves at the ends of the fastening beam 2131 can be seen from FIG. 7). Thereby, the connection and fixation between two adjacent fastening beams 2131 can be completed. By using such a structure, the stability between two adjacent fastening beams 2131 can be greatly improved. Furthermore, the connection between adjacent roof plates is realized, which is highly flexible, highly practical, and easy to install, and can greatly accelerate the construction speed.

[0041] Furthermore, referring to FIGS. 6 and 7, serrated slide bars 21321 are provided on the side walls at both ends of the slide bar 2132. A concave groove 21336 is formed at the top of the slide block 2133. The concave groove 21336 is slidably connected to the slide bar 2132. Serrated pin holes 21335 are formed on both the front and rear sides of the slide block 2133. The serrated pin holes 21335 and the serrated slide bars 21321 are locked by serrated pins 21334. During the assembly process, when an operator needs to adjust the distance between two adjacent slide blocks 2133, the length between the fastening beams 2131 of the slide bar 2132 can be adjusted, that is, the adjustment can be made by sliding the slide bar 2132 into the slide block 2133. After adjusting to the required position, the slide block 2133 and the slide bar 2132 can be locked with the serrated pin 21334.

[0042] Referring to FIGS. 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, and the inner engaging member 2182 includes an engaging bolt that fits into the inner engaging groove. The engaging bolt is inserted and engaged with the inner engaging groove to surround and form an engaging groove for the bracket. The top protrusion of the outer engaging member 2181 wraps 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 externally, the outer engaging member 2181 further wraps the inner engaging member 2182, thereby realizing the double self-locking of the self-locking assembly 218 and ensuring the stability of the self-locking assembly 218. Engagement grooves are opened on both the inner side of the outer engaging member 2181 and the inner side of the inner engaging member 2182, and the fixing bracket 2183 is engaged with the engaging groove for the bracket formed by the two sets of engaging grooves. That is, the outer contour of the fixing bracket 2183 fits into the engaging groove for the bracket, and the edges on both sides of the upper roof plate 214 are restricted between the engaging groove for the bracket and the fixing bracket 2183. It should be noted that the engaging groove for the bracket is composed of two upper and lower parts, the upper part is a fan-shaped concave groove, and the lower part is a rectangular concave groove (shown in FIGS. 12 and 13).

[0043] Furthermore, when the self-locking assembly 218 and the fixing bracket 2183 lock the upper roof plate 214 and the connecting plate 22, the ends of the upper roof plate 214 and the connecting plate 22 may be surrounded outside the fixing bracket 2183. At this time, the fixing bracket 2183 supports the upper roof plate 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 plate 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 plate 214 and the connecting plate 22 from the outside. Here, it should be noted that two layers of connecting plates 22 or adjacent roof plates may be further overlapped on the top of the upper roof plate 214, and then locked by the self-locking assembly 218. In such a case, it can be seen when joining two adjacent sets of roof modules, as can be seen from FIG. 4.

[0044] Referring to FIG. 12, the fixed bracket 2183 includes a positioning horizontal plate and a limiting vertical bar provided perpendicular to the positioning horizontal plate. The limiting vertical bar has a structure that is wider at the top and narrower at the bottom, and the 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 concave portions and protrusion portions are sequentially provided downward along both sides of the arc-shaped protrusion, and the multi-stage structure is integrally formed with the limiting vertical bar.

[0045] FIG. 13 shows another embodiment of the fixed bracket 2183. The structure that is wider at the top and narrower at the bottom is also used, but there are differences at the top, and it may be applied to the overall roof of the present invention.

[0046] As shown in FIG. 8, the upper roof plate 214 has side edges that conform to the shape of the limiting vertical bar, and its top is also an arc-shaped protrusion. Concave portions and protrusion portions are sequentially provided downward along both sides of the arc-shaped protrusion, and the multi-stage structure is integrally formed with the upper roof plate 214.

[0047] Referring to FIG. 10, both sides of the solar panel 217 are fitted and attached to the insert plates 219. Two sets of insert plates 219 are provided, and they are removably attached above two sets of mounting brackets 216 respectively. It should be noted that the outside of the insert plate 219 is further fixed to the opening of the mounting bracket 216 by bolts with an L-shaped connecting plate, thereby improving the stability of the insert plate 219. On the premise of meeting the Chinese national technical standards using solar power generation, energy storage, DC, and flexibility technologies, the solar panel is fixed to the top of the self-locking assembly 218 by an insertion method, thereby realizing "energy storage" and "power supply", and changing the building's power demand from rigidity to flexibility.

[0048] Referring to FIGS. 14, 19 and 21, when the skylight is applied to a corrugated roof, the heights of the regions of the corrugated roof are 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 greatest. Therefore, in the present application, the pressure reduction adjustment assemblies 32 are installed at the four corner positions of the skylight 31 on the ridge. Since the negative wind pressure on the ridge is the greatest, it is an optimal embodiment when the pressure reduction adjustment assemblies 32 are installed on the ridge (shown in FIG. 14), and the balance of the negative wind pressure received by the skylight 31 on the ridge can be achieved. When a linear sudden change occurs on the ridge, the pressure reduction adjustment assembly 32 is suitable for use on the skylight on the ridge, and the balance of the negative wind pressure received by the skylight 31 can be achieved. When the generated negative wind pressure exceeds the pressure set in the pressure reduction adjustment assembly 32, the pressure reduction adjustment assembly 32 can perform pressure reduction. When the generated negative wind pressure is lower than the pressure set in the pressure reduction adjustment assembly 32, the skylight has already been damaged. At this time, the elastic member in the pressure reduction adjustment assembly 32 bounces the pressure reduction device to open the pressure reduction hole for pressure reduction, thereby ensuring that the skylight on the ridge has good support performance. Of course, the pressure reduction adjustment assemblies 32 may also be installed on the skylight 31 in the sloping roof region and the flat roof of the corrugated roof (shown in FIGS. 18 and 20), and specifically whether to install and the installation position are 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] Referring to FIGS. 14 and 15, the pressure reducing device 32 includes an angle pipe 321, an elastic member 322, a pressure reducing hole 323, a support plate 324, a single plate 325, an inner insertion rod 326 and an outer sleeve 327. The top of the inner insertion rod 326 is connected to the angle pipe 321, the bottom of the outer sleeve 327 is fixed to the lower roof plate 212, the bottom of the inner insertion rod 326 is slidably connected into the outer sleeve 327, the pressure reducing hole 323 is opened in the outer sleeve 327, the top of the outer sleeve 327 is connected to the angle pipe 321 by the elastic member 322, the top of the angle pipe 321 is fixed to the skylight 31, one end of the single plate 325 is connected to the angle pipe 321 by the support plate 324, the angle pipe 321 is provided on the side surface of the skylight 31, a spacer is further provided at the contact position between the inner insertion rod 326 and the outer sleeve 327, the spacer is fixed to the inner wall of the outer sleeve 327, and the spacer is located below the pressure reducing hole 323. Here, in order to prevent water from entering the slit between the inner insertion rod 326 and the outer sleeve 327 and affecting subsequent use, a gasket may be used. When the inner insertion rod 326 slides upward in the outer sleeve 327, the pressure reducing hole 23 will be exposed, and at this time, pressure reduction is realized. When the inner insertion rod 326 slides downward in the outer sleeve 327, the pressure reducing hole 323 will be shielded, and at this time, sealing is realized.

[0051] When negative external wind pressure acts on the skylight 31 in the building, the skylight 31 in the building is moved so as to move upward as a whole, and further, the insertion rods 326 on both sides of the skylight are moved so as to slide upward in the outer casing 327. When the pressure relief holes 323 on the insertion rods 326 are exposed, the pressure relief holes 323 can realize the pressure relief treatment 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 under the action of external negative wind pressure, the skylight 31 is moved so that the elastic members 322 on both sides are pulled. After the pressure relief is completed, it will return to its original position under the action of the elastic member 322. Moreover, when the pressure sensor 37 detects that the negative wind pressure exceeds the pressure set for the pressure relief device, the elastic member 322 operates to move the skylight 31 upward as a whole to perform pressure relief through the pressure relief holes. When the generated negative wind pressure becomes lower than the pressure set in the pressure relief adjustment device 32, the skylight may already be at risk of being damaged. At this time, the elastic member 322 in the pressure relief adjustment device 32 is manually controlled to make the pressure relief device bounce, open the pressure relief holes for pressure relief, thereby ensuring that the skylight in the building has good support performance. It should be noted that the elastic member 322 may select a general spring or damper. 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 by bolts or pins or welding.

[0052] Referring to FIG. 14, the drain plates 34 include four sets, which are respectively attached to the four side surfaces of the skylight 31. The top of the drain plate 34 is fixed to the outer casing 326, and there is a slit between the bottom and the lower roof plate 212. The installation of the drain plate 34 can achieve a certain waterproof effect on the connection part between the skylight 31 and the lower roof plate 212. At the same time, the bottoms of the four side surfaces of the skylight 31 and the lower roof plate 212 are fixed by the first anti-permeation assembly 33. The installation of the first anti-permeation assembly 33 can further ensure the waterproof effect of the connection part between the skylight 31 and the lower roof plate 212.

[0053] Furthermore, referring to FIG. 16, the first anti-permeation assembly 33 includes a folded plate 331 and a corner joining member 332. The folded plate 331 is located at the bottom of the side surface of the skylight 31. One end of the folded plate 331 is fixed to the skylight 31 by welding, and the other end is fixed to the lower roof plate 212 by welding. Moreover, the corner joining portions of two adjacent folded plates 331 are fixed by the corner joining member 332. The corner joining member 332 is exactly at the four corner positions of the skylight 31, that is, the four corner joining members 332 are for connecting the folded plates 331 on the four side surfaces. Furthermore, the sealing performance between the entire skylight 31 and the lower roof plate 212 is ensured.

[0054] Furthermore, referring to FIGS. 17 and 18, the folding plate 331 includes an integrally formed skylight welding portion 3311, a vertical overlapping joint portion 3312, a corrugated protrusion portion 3313, and a roof welding portion 3314. The skylight welding portion 3311 is fixed to the bottom of the side surface of the skylight 31, the roof welding portion 3314 is fixed to the lower roof plate 212, both the corrugated protrusion portion 3313 and the roof welding portion 3314 are provided at both ends of the folding plate 331, the roof welding portion 3314 is for welding the roof, and the corrugated protrusion portions 3313 of two adjacent folding plates 331 are fixed by the corner joint member 332, and the two may use fixing attachments such as bolt fixing or welding. The two adjacent vertical overlapping joint portions 3312 are also fixed by the corner joint member 332, the vertical overlapping joint portion 3312 is overlapped with the corner joint member 332, and the two may use fixing attachments such as bolt fixing or welding. The corner joint member 332 includes an upper connection portion 3321 and an arc-shaped overlapping joint portion 3322. The upper connection portion 3321 is provided at the top of the arc-shaped overlapping joint portion 3322, and the upper connection portion 3321 includes two welding sides presenting a vertical shape. The two welding sides are welded to the bottom of the corner of the skylight 31. The arc-shaped overlapping joint portion 3322 connects two adjacent corrugated protrusion portions 3313 and is fixed to the corrugated protrusion portion 3313 by welding. It should be noted that the corrugated protrusion portion 3313 is a corrugated structure with unevenness, and the connection positions of the arc-shaped overlapping joint portion 3322 and the corrugated protrusion portions 3313 on both sides also use corresponding corrugated structures with unevenness and just fit with the corrugated protrusion portions 3313 on both sides, thereby increasing the contact area between the two, ensuring the stability and waterproof effect during the welding of the two. The bottom of the arc-shaped overlapping joint portion 3322 is welded to the roof.

[0055] Referring to FIG. 19, at the same time, the skylight 31 applied to the pitched roof (or the sloping roof) is based on the above-mentioned one, and further includes a second anti-permeation assembly 36 provided at the boundary between the skylight 31 and the ascending slope of the pitched roof (shown in FIG. 19). Since rainwater flows downward along the pitched roof from the top of the building, it will concentrate at the boundary between the skylight 31 and the ascending slope of the pitched roof. Therefore, by providing the second anti-permeation assembly 36 at the boundary between the skylight 31 and the ascending slope of the pitched roof, it is possible to prevent the rainwater flowing from the ascending slope to the descending slope from affecting the seal between the skylight 31 and the roof slab, and further prevent water leakage from occurring on the roof. In the installation here, the second anti-permeation assembly 36 can achieve primary water stoppage between the skylight 31 and the roof slab, while the first anti-permeation assembly 33 between the skylight 31 and the roof slab achieves a secondary water stoppage effect, thereby further ensuring the seal between the skylight 31 and the roof slab.

[0056] Furthermore, referring to FIG. 20, the second anti-permeation assembly 36 includes an anti-permeation plate 361 and an anti-permeation joint plate 362. One end of the anti-permeation plate 361 is fixed to the side surface of the skylight 31 by welding or bolts, and the other end is fixed to the lower roof slab 212 by the anti-permeation joint plate 362. The top of the anti-permeation joint plate 362 is welded to the anti-permeation plate 361, and the bottom of the anti-permeation joint plate 362 is welded to the lower roof slab 212. The anti-permeation plate 361 presents a "C" - shaped structure, and the arc-shaped opening of the "C" - shape faces the ascending slope surface. Such an installation arrangement is not easy for water to accumulate. The anti-permeation joint plate 362 presents an "S" - shaped structure, and it may also be set in a "C" - shape or other shapes, specifically determined according to the actual situation on site. What is given in FIG. 19 of the present application is an "S" - shaped structure, and the "S" - shaped structure of the present application is the optimal embodiment. An "S" - shaped anti-permeation joint plate is installed between the "C" - shaped anti-permeation plate and the roof. Compared with a right-angle connecting member, the connection location of the "S" - shaped anti-permeation joint plate transitions smoothly, reducing connection displacement due to stress concentration. And the connection locations of the "S" - shaped anti-permeation joint plate, the "C" - shaped anti-permeation plate and the roof may also be connected by rivets. Specifically, blind rivets can be selected and sealed with a sealing material to reduce the connection contact area between the "C" - shaped anti-permeation plate and the roof, making the connection more reliable.

[0057] Referring to FIG. 22, when the gutter system 4 is on a flat roof, the operator can install a plurality of gutters at the edge of the roof or in the center of the roof according to actual needs for drainage. However, when the gutter system 4 is on a corrugated roof, the operator can install the gutter at the trough position according to actual needs. By installing it at the trough position, the entire rainwater accumulated on the roof can be discharged from the gutter 41 without affecting the roof. When specifically installing the gutter 41, it is provided at the eaves of the lower roof panel 212. A rainwater inlet is opened on the inner bottom wall of the gutter 41, and a siphon roof drain 42 is attached to the rainwater inlet. The bottom of the rainwater inlet communicates with the rainwater pipe 49. The inside of the rainwater pipe 49 is provided with a rainwater pipe trace tape 46 and is connected to a connection box 48 provided on the inner wall of the gutter. A eaves snow melting and deicing assembly 43 is provided on the upper eaves of the gutter 41 to realize snow melting and deicing treatment for the eaves of the roof, preventing the icicles formed on the eaves from falling into the gutter 41 and causing damage to the gutter. A water pressure monitor 44 for detecting the water pressure inside the gutter 41 is provided on the side wall of the gutter 41. A gutter snow melting and deicing assembly is provided inside the gutter 41, and the gutter snow melting and deicing assembly can realize snow melting and deicing treatment inside the gutter.

[0058] Referring to FIGS. 27 and 28, the siphon roof drain 42 includes a conical drainage part 421, a spacer 422, an inclined spiral part 423 and a drain outlet 424. The conical drainage part 421 is provided at the top of the inclined spiral part 423. The spacer 422 is located outside the inclined spiral part 423. The inclined spiral part 423 communicates with the drain outlet 424 at the bottom. During installation, the inclined spiral part 423 is connected to the pipe at the rainwater inlet, and the spacer 422 is in close contact with the rainwater inlet, thereby ensuring the seal between the inclined spiral part 423 and the rainwater inlet pipe. The drain outlet 424 is connected to the rainwater pipe 49. During use, rainwater flows from the conical drainage part 421 into the inclined spiral part 423 and is discharged from the drain outlet 424 into the rainwater pipe 49. By installing the rainwater pipe trace tape 46, the inside of the rainwater pipe 49 can be heated, thereby preventing the temperature inside the rainwater pipe 49 from being too low and freezing, which may cause blockage of the pipe. It should be noted that by installing threads on the outside of the inclined spiral part 423, not only the stability during installation can be ensured, but also the heat generated by the rainwater pipe trace tape 46 in the rainwater pipe 49 can be prevented from having a temperature effect on the water inlet, and the heat dissipation effect of the siphon roof drain 42 can be enhanced.

[0059] Furthermore, the spacer 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 type spacer. The expansion layer 4221 is located outside 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 part with the expansion layer. The honeycomb layer can prevent the spread of fragmentation when a certain part is damaged, 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 type siphon roof drain spacer will 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 about 30 mm.

[0062] Example 2 The total diameter of the integrated siphon roof drain spacer 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.

[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 expansion 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 expansion 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 expansion 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 expansion layer is 18 mm.

[0067] Heat dissipation function test Examples 1 to 5 in Table 1 are the test results of the integrated spacers. JPEG2025517045000002.jpg28170

[0068] As can be seen from Table 1, although the surface temperature changes of the spacers in Examples 2 to 5 are all less than 5 °C, the temperature rise of Comparative Example 1 without adding an expansion layer is higher than 10 °C, which explains that this new spacer has a better heat dissipation function and the heat dissipation function improves with the increase in the area of the expansion layer.

[0069] Referring to FIGS. 22 and 23, the eaves snow melting and deicing assembly 43 is provided at the top of the roof and the upper eaves position of the gutter 41. The eaves snow melting and deicing assembly 43 includes an eaves cap 431, a heat insulation layer 432, a heat conduction pad 433, a heating cable 434, and a second drain plate 435. The eaves cap 431 is located at the end of the roof, the heat conduction pad 433 and the heat insulation layer 432 are sequentially laid at the end of the roof, the heating cable 434 is located on the heat conduction pad 433, the heating cable 434 is connected to the solar panel 217 on the roof, the second drain plate 435 is provided below the eaves cap 431, and there is a slit between the second drain plate 435 and the lower roof plate 212. The water flow can flow out from the second drain plate 435 through the eaves cap 431 without seeping into the roof and affecting the roof.

[0070] It should be noted that by installing the heating cable 434, that is, the electric trace tape, on the upper eaves of the gutter, it is possible to melt the ice and snow under the ice and snow weather on the upper eaves of the gutter, and it is difficult to cause the problem that the "icicle" formed by freezing clogs the upper eaves of the gutter and the roof is difficult to drain immediately under the rain and snow weather. At the same time, it is possible to avoid the situation that the shape such as the "icicle" suddenly falls and damages the inside of the gutter when melting. At the same time, the device connects the heating cable 434 to the solar panel 217 on the roof, installs the heat conduction pad 433 on the heating cable 434, and installs the heat conduction pad 433 at the same distance from the contact part below the heating cable 434 to the eaves, thereby strengthening the heat and area generated by the heating cable 434. The heat insulation layer 432 is arranged at the distance from the eaves cap below the heat conduction pad 433 to the heating cable, thereby avoiding the heat transmitted from the heat conduction pad 433 from causing a temperature effect and affecting the lower structure. At the same time, the eaves cap 431 can prevent water droplets from seeping into the roof. The solar panel 217 can supply energy to the heating cable 334 and the water pressure monitor 34 in the eaves snow melting and deicing assembly 43.

[0071] Referring to FIG. 24, the gutter snow melting and deicing assembly includes a gutter trace tape 471 and a concave groove formed in the heat conduction plate 410. The concave groove presents a "snake" - shaped structure, and the gutter trace tapes 471 are all laid in the concave groove in a snake - like manner. Moreover, the gutter trace tape 471 is connected to the solar panel 217 on the roof. This method melts and deices the snow by attaching a trace tape in the gutter and heating it.

[0072] It should be noted that by opening a "snake" - shaped concave groove in the heat conduction plate and laying the gutter trace tape 471 in the concave groove, the gutter trace tape 471 also presents a "snake" - shaped structure. Thereby, the covering area of the trace tape in the gutter 41 can be increased, solving the problem that the area - covering rate of the electric trace tape generating heat on the surface of the gutter 1 is small and energy is saved. The heat conduction plate material may preferably be a material with higher thermal conductivity such as metal or ceramic. This application can generate uniform heat over a large area with a relatively small number of electric trace tapes to cover the entire gutter 41, enabling the ice and snow to melt immediately under ice - snow weather. When the area of the gutter 41 is relatively small, the area ratio of the "snake" - shaped heat conduction plate can be appropriately reduced, and one "snake" - shaped concave groove can be installed inside (FIG. 24 shows a schematic diagram of opening one concave groove in the gutter and laying one trace tape, while FIG. 23 shows the case of opening two concave grooves in the gutter and laying two trace tapes). Specifically, how many concave grooves to open and how many trace tapes to install are determined according to the actual dimensions of the gutter and the on - site requirements. This application is not limited and only gives two implementation forms. The purpose of this device is to generate a large area of heat on the surface of the gutter with a relatively small number of electric trace tapes and achieve the effect of immediately melting ice and snow based on energy conservation.

[0073] Referring to FIG. 26, in another embodiment, it is basically the same, but the differences are as follows. The gutter snow melting and deicing assembly includes an intelligent spray member 472, and the intelligent spray member 472 further includes a pipe 4721, a high-pressure nozzle 4722, an automatic spray control module 4723 and a snowfall sensor 4724. A plurality of high-pressure nozzles 4722 are provided, all of which are laid on the side wall of the gutter 41 at equal distances. The plurality of high-pressure nozzles 4722 are communicated by the pipe 4721. It should be noted that the specific number of high-pressure nozzles 4722 installed is determined by the size of the gutter and the actual installation situation, and the present application is not limited here. The automatic spray control module 4723 and the snowfall sensor 4724 are provided at the end of the side wall of the gutter 41. One end of the pipe 4721 communicates with the deicing agent storage box body, and the deicing agent is salt water or a snow melting agent. The deicing agent in the deicing agent storage box body 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 to realize snow melting and deicing in the gutter. This method realizes snow melting and deicing treatment by installing a device that sprays salt water or a snow melting agent into the gutter. It should be noted here that this intelligent spray scheme is a reinforcement based on the heat conduction plate 410. The gutter trace tape 471 can melt ice and snow by dissipating a large amount of heat to the heat conduction plate 410. However, substances such as salt water and snow melting agent sprayed intelligently can also melt ice and snow to enhance the snow melting effect in the gutter.

[0074] It should be noted that by installing the intelligent spray member 472, snow in the gutter can be removed in winter, and the function of cooling the inside of the gutter can be achieved in summer. The pipe 4721 is attached to the inner walls on both sides that are 0.1 - 0.3 m away from the bottom of the gutter. The specific installation height is determined by the on-site installation situation or the actual dimensions of the gutter. This application is not limited and only provides a suitable range value for reference. The snowfall sensor 4724 and the automatic spray system 4723 are simultaneously connected to the pipe 4721 of this application. The snowfall sensor 4724 can sense the snowfall amount and temperature. When it snows in winter and the temperature is below 0°C during snowfall, when the snowfall sensor 4724 receives a signal, the automatic spray control module controls the spraying of de-icing agents, etc., and can further control the spraying amount based on the snowfall amount. Especially when it suddenly snows at night, the system immediately operates to prevent the snow from freezing in the gutter. In summer, in a hot climate, the automatic spray system 4723 may be set to control the spraying of clean water within a certain temperature range to cool down and protect the members, extend the service life. This device can melt and de-ice the gutter, and at the same time, it can effectively prevent the phenomenon that the metal roof generates a temperature difference and causes water leakage at the connection part due to the temperature effect, resulting in the roof becoming loose and not firm.

[0075] A roof equipment box is provided inside the roof. The inside of the roof equipment box includes an inverter, an energy storage module, a load, a water pressure signal transmission module, and a heating control module that are sequentially connected 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 stores the electrical energy formed by the conversion of the inverter and is used to transport the electrical energy to the power consumption load. The heating control module controls the operating state, heating time, and adjusted temperature of the electrical trace tapes at various locations. The water pressure signal transmission module is connected to the water pressure monitor 44 and is used to transmit the water pressure value inside the gutter detected by the water pressure monitor 44. When it is detected that the water pressure value of the gutter is abnormal, inspection and maintenance are immediately carried out.

[0076] The specific installation principle of the roof body of this application is as follows. Before assembly, first, before assembling the metal roof, it is necessary to build an assembly platform on the ground in the span direction of the factory building. The height of the assembly platform should reach the height of the roof column 1 and meet the load requirements. Furthermore, temporary sliding rails for assembly should be installed on the roof column beams of the factory building. Second, arrange the steel-structured factory buildings by area, assemble them by area. For structures with a relatively large span, it is necessary to fix multiple roofs on the assembly platform and then perform overall sliding installation. Third, by installing bolt holes on the beams of the roof columns, it is made easier to slide the roof module to the designated position and fix it with bolts.

[0077] It should be noted that the bottom of the assembly platform is supported by multiple support columns, and the top of the platform may be slightly lower than the height of the roof column. During installation, the operator transports the parts to the platform and then directly assembles them above the assembly platform, thereby facilitating the erection of the entire module on the roof column. The assembly platform is not the scheme protected by this application, and the assembly platform is more common in the current construction site. Since this application uses the assembly platform, it is briefly described here.

[0078] Regarding the assembly method of a single roof module of this application, During assembly, transport the preform of the factory roof module 21 to the site, and assemble a single roof module 21 on the assembly platform. First, attach the lower roof plate 212 above the support beam 211, attach a slide shoe to the bottom of the support beam 211, and the slide shoe can slide on the slide rail. In sequence, lay the fastening beam 2131, slide block 2133 and slide bar 2132 above the lower roof plate 212, and lock the three of them. Then, attach the self-locking assembly 218 above the slide bar 2132, and use the self-locking assembly 218 to fix the upper roof plate 214. Place the heat-insulating and moisture-proof layer 215 in each gap between the fastening beam 2131 and the slide bar 2132. The heat-insulating and moisture-proof layer 215 is, in order from bottom to top, a moisture-proof layer, a heat-insulating layer and a waterproof layer. Finally, attach the solar panel 217 above the self-locking assembly 218. Slide the assembled single roof module 21 along the slide rail on the roof column to the designated position on the roof. Then, lift up the roof module with a jack. The jack lifts up the upper support beam 211 and slowly places the entire module on the roof column and then fixes it as a whole. Remove the slide shoe and the corresponding part of the slide rail, and then fixedly connect the roof module 21 to the roof column 1. It should be noted here that when the span between the roof column and the column is extremely large, a temporary steel column may be installed at the center in the span direction. The height of the temporary steel column is the same as that of the left and right roof columns. Also place a slide rail on the temporary column. The sliding steps are the same as above. After the roofs of the units on both sides slide to the designated position simultaneously, bolt-connect the support beams 11 at the bottoms on both sides. Further, remove some of the slide rails with a jack. After that, a waterproof reinforcement assembly 24 is laid at the connection position of two adjacent roof modules 21, and the two roof modules 21 are connected by a connection plate 22 above the waterproof reinforcement assembly 24. Pay attention to the arrangement of dimensions and the misalignment and overlapping splicing of the front and rear roof plates during assembly. When the span of the factory building is too large, after installing multiple modules, perform a sliding installation as a whole, and it is necessary to perform a check calculation on the load stability of the assembly platform. When the span of the factory building is too large, use the temporary steel columns described above for assistance. The steps refer to the description of the temporary steel columns, and perform the above steps in sequence to assemble the entire roof by block and then slide it to the designated position. Fine-tune the roof through the fine-tuning system between the fastening beam 2131, the slide bar 2132, and the slide block 2133 in the roof system itself, thereby realizing the overall roof effect.

[0079] In the process of assembling the roof body 2, the operator also needs to install and arrange the skylight system 3 and the gutter system 4 as required. The specific installation positions and quantities are determined by the on-site conditions and the dimensions and shapes of the roof body 2.

[0080] When the skylight system 3 is used after installation, when facing rainy and cloudy weather during use and the external negative wind pressure acts on the roof, different wind pressures will be generated at different positions of the roof. The negative wind pressure in the building is the largest. Then, the skylight 31 installed in the building will also receive the largest negative wind pressure correspondingly, and further move the skylight 31 upward. When the negative wind pressure is large, the skylight 31 may be crushed. The corresponding negative wind pressure is on the slope surface. The negative wind pressure received by the slope surface is smaller than that of the building, but it is also affected by the negative wind pressure. Therefore, the pressure reduction device is installed at the skylights 31 in all three locations of the flat roof, the slope roof, and the building.

[0081] When an external negative wind pressure acts on the skylight 31 in the building, the skylight 31 in the building is moved so as to move upward as a whole, and further the insertion rods 326 on both sides of the skylight are moved so as to slide upward in the outer casing 327. When the pressure reducing holes 323 on the insertion rods 326 are exposed, the pressure reducing holes 323 can realize the pressure reducing treatment 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 under the action of an external negative wind pressure, the skylight 31 is moved so that the elastic members 322 on both sides are pulled. After the pressure reduction is completed, it will return to its original position under the action of the elastic member 322. And when the pressure sensor 37 detects that the negative wind pressure exceeds the pressure set for the pressure reducing device, the elastic member 322 operates to move the skylight 31 upward as a whole to perform pressure reduction through the pressure reducing holes. When the generated negative wind pressure is lower than the pressure set in the pressure reducing adjustment device 32, the skylight may already be in danger of being damaged. At this time, the elastic member 322 in the pressure reducing adjustment device 32 is manually controlled to make the pressure reducing device bounce, open the pressure reducing holes for pressure reduction, thereby ensuring that the skylight in the building has good support performance.

[0082] And since it is necessary to ensure that the connection locations between the four side surfaces of the skylight 31 and the lower roof plate 212 have excellent sealing effects, a first anti-permeation assembly 33 is installed at the connection locations between the two. The engagement between the folding plate 331 and the corner joint member 332 realizes the sealing performance of the connection location between the entire skylight 31 and the lower roof plate 212. Moreover, the installation of the corrugated protrusions 3313 on the folding plate 331 can prevent rainwater from passing through the corrugated protrusions 3313. The corrugated protrusions 3313 block rainwater multiple times, further ensuring the sealing effect of the connection location between the skylight 31 and the lower roof plate. The first drain plate 34 can receive rainwater from above hitting the connection location between the skylight 31 and the lower roof plate 212. When the rainwater falls on the first drain plate 34, the first drain plate 34 provides a certain shock mitigation, and then it slides off the first drain plate 34 to the roof. It should be noted that the first anti-permeation assembly 33 is installed at the skylights in all three locations: the flat roof room, the sloped roof room, and the building.

[0083] And, in the case of the slope surface, especially the upward slope surface, since rainwater slides down along the slope surface from the highest building, it is necessary to further prevent infiltration and fix the seal between the skylight 31 and the lower roof board on the upward slope surface. Therefore, a second anti-infiltration assembly 36 is added below the first drainage board 34 on the upward slope surface, and the second anti-infiltration assembly 36 is added to the tip of the first anti-infiltration assembly 33. That is, the rainwater can be blocked for the first time by the anti-infiltration plate 361 and the anti-infiltration joint plate 362, and then the rainwater is blocked for the second time by the first anti-infiltration assembly 33, thereby further ensuring the sealing effect between the skylight 31 and the lower roof board on the upward slope surface.

[0084] When the gutter system 4 is installed and used, when facing rainy and snowy weather, rain and snow will flow from the roof into the gutter 41 on the eaves of the roof. Since the gutter 41 is concave and there is a certain height between its interior and the eaves of the gutter, there is a risk of icicles forming on the upper eaves in rainy and snowy weather. Therefore, by installing the eaves snow melting and deicing assembly 43, the icicles can be removed. During the removal process, by installing the heating cable 434 and the heat conduction pad 433, the snow melting and deicing treatment at high temperature can be realized, and the melted rainwater can flow from the second drainage board 435 into the gutter 41 under the action of the eaves cap 431, thereby preventing the formation of icicles on the upper eaves of the gutter.

[0085] And, the rainwater that has fallen into the gutter 41 has a risk of freezing due to the low outdoor temperature environment, and there is a risk of snow accumulating in the gutter. However, since the gutter is at a high place, it is difficult to remove it manually. Therefore, by installing a gutter snow melting and deicing assembly in the gutter 41, the snow melting and deicing treatment inside the gutter 41 can be realized. Specifically, when processing, there are two selection methods. The first is to install a trace tape inside the gutter to realize snow melting and deicing, and the second is to install something for spraying a snow melting agent on the inner wall of the gutter to realize snow melting and deicing.

[0086] When realizing snow melting and ice thawing inside the gutter by selectively using the trace tape, one gutter trace tape 471 or two gutter trace tapes 471 are selectively used according to the dimensions of the gutter 41 and the actual situation on site. The activation of the gutter trace tape 471 is controlled by the heating control module in the indoor roof equipment box under rainy and snowy weather conditions. The inside of the gutter 41 is heated by the gutter trace tape 471, thereby realizing the snow melting and ice thawing treatment of the accumulated snow or ice blocks inside the gutter. After the accumulated snow and ice blocks melt into rainwater, they can fall from the siphon roof drain 42. When entering the siphon roof drain 42, the rainwater pipe trace tape 46 in the rainwater pipe 49 also starts to operate. The rainwater pipe trace tape 46 is also controlled by the roof equipment box. The rainwater pipe trace tape 46 can prevent rainwater from freezing in the rainwater pipe 49 in a low-temperature environment. Finally, it just needs to fall to the ground through the rainwater pipe 49. Energy is supplied to the rainwater pipe trace tape 46 and the gutter trace tape 471 by the solar panel 217.

[0087] When selecting and using the method of spraying deicing agent to achieve snow melting and ice thawing, the high-pressure nozzles 4722 are laid inside the gutter 41 according to the dimensions of the gutter 41 and the actual situation of the site. A plurality of high-pressure nozzles 4722 are communicated by the pipe 4721 and can be connected to the automatic spraying control module and the snowfall sensor 4724. However, the inlet of the pipe 4721 is connected to the external deicing agent storage box body. During use, the automatic spraying control module 4723 is controlled to operate by the roof equipment box. The automatic spraying control module 4723 imports the deicing agent in the deicing agent storage box body into the pipe 4721, and then controls it to spray out from a plurality of high-pressure nozzles 4722 into the inside of the gutter 41 to act on the ice blocks or accumulated snow inside the gutter 41, thereby realizing the snow melting and ice thawing treatment. After the accumulated snow and ice blocks melt into rainwater, they can fall from the siphon roof drain 42. When entering the siphon roof drain 42, the rainwater pipe trace tape 46 in the rainwater pipe 49 also starts to operate. The rainwater pipe trace tape 46 is also controlled by the roof equipment box. The rainwater pipe trace tape 46 can prevent rainwater from freezing in the rainwater pipe 49 in a low-temperature environment. Finally, it can just fall to the ground through the rainwater pipe 49. The rainwater pipe trace tape 46, the automatic spraying control module 4723 and the snowfall sensor 4724 are supplied with energy by the solar panel 217.
