Description

Technical Field

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

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

[0003] In terms of construction quality, when the metal roof panels are integrally installed, the joints are prone to loose connection and deformation. In addition, the connection methods between the components of the roof panels usually adopt mechanical connections such as locking, biting, or clamping forms, with low connection stiffness. When subjected to strong wind loads or ordinary wind loads with specific wind vibration frequencies, wind uplift accidents occur. For example, in the existing patent document with the publication number CN218176365U and the patent name of a reinforcing snap-fit structure for metal roof panels, it specifically discloses that "it includes a ridge cover and a ridge connecting piece, and an elastic traction device for pulling the two side plates of the ridge cover towards the center is installed inside the ridge cover; the ridge cover of the present invention is pulled by the elastic traction device inside it, so that the two side plates of the ridge cover are pulled inwards, and in cooperation with the snap-fasteners on the ridge cover, the connection strength between the ridge cover and the ridge connecting piece can be increased, and the risk of the ridge cover being blown off by strong winds can be reduced". Although the above technology can increase the wind uplift resistance of metal roof panels to a certain extent, it often adopts a multi-point layout form, with a dense layout and each point acting independently. The fixed points cannot cooperate in force, have low stability, and may fall off in extreme cases.

[0004] In terms of construction safety, since steel structures require high-altitude operations, their construction workers often have safety hazards during high-altitude operations, and precision control during the construction process is also a difficult point. Moreover, the safety and precision control of the overall hoisting of the steel structure roof directly determine the subsequent overall construction quality of the steel structure and are also an important part of the entire building construction project. The characteristics of low load-bearing capacity and large area of metal roof panels result in high labor costs, serious material consumption, and inability to achieve efficient and economic utilization of the roof system. Summary of the Invention

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

Multiple reinforcement points work together with high utilization rate to ensure the stability and bearing capacity of the integral roof, and solve the problems of low bearing capacity and large area of the metal roof panel. At the same time, the method of prefabricating modules separately and then splicing is flexible in operation, convenient for installation, can also speed up the construction progress, and ensure the safety of construction workers.

[0027] The present invention also discloses an installation method for an assembled sliding and splicing roof, including the following steps:

[0028] S1. Before assembly, first set up an overall assembly platform in the span direction of the metal roof columns, and install temporary assembly slide rails on the roof columns;

[0029] S2. Divide the overall roof into intervals and perform individual assembly on each interval;

[0030] S3. Transport the prefabricated parts of the factory roof module to the site and perform the assembly of a single roof module on the assembly platform;

[0031] S4. Slide the assembled single roof module to the designated position on the roof by using the slide rails on the roof columns, then lift the roof module by using a hoisting member, and after removing the corresponding sectional slide rails, fixedly connect the roof module to the roof columns;

[0032] S5. Then lay a waterproof strengthening component at the joint of two adjacent roof modules, and connect the two roof modules by using a connecting plate above the waterproof strengthening component;

[0033] S6. Slide and splice into an overall roof in sequence according to the divided intervals.

[0034] The present invention prefabricates flat or special-shaped roof modules in sections on the ground, and with the assistance of an assembly platform and assembly slides on roof columns, after the overall modules are prefabricated, they are slid using the slides, and at the same time, they are hoisted using hoisting components, so that the assembly operation can be realized on the roof, and then an overall roof system is formed, which can form a flat roof, an arc-shaped roof or a combination of the two. The installation method of the present invention can improve the installation accuracy, optimize the work efficiency, reduce the fixed installation time, shorten the construction progress, reduce resource consumption, and at the same time meet the requirements of different types of roof forms, realizing the applicable range of standardized flat modules and special-shaped modules and putting forward a sectional hoisting construction method for easy popularization and application.

[0035] As a further solution of the present invention: the method for assembling a single roof module in step S3 is as follows:

[0036] S31. Then install the lower roof panel above the support beam, and install sliding shoes at the bottom of the support beam, and the sliding shoes can slide on the slide rail;

[0037] S32. Lay a fastening beam, a module and a sliding rod above the lower roof panel in sequence, and lock the three of them. Then install a self-locking component above the sliding rod, and fix the upper roof panel using the self-locking component;

[0038] S33. Place a thermal insulation and vapor barrier component at each gap between the fastening beam and the sliding rod. The thermal insulation and vapor barrier component includes a vapor barrier layer, a thermal insulation layer and a waterproof layer from bottom to top in sequence;

[0039] S34. Finally, install a solar panel above the self-locking component.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] First, the present invention prefabricates flat or special-shaped roof modules in sections on the ground, and with the assistance of an assembly platform and assembly slides on roof columns, after the overall modules are prefabricated, they are slid using the slides, and at the same time, they are hoisted using hoisting components, so that the assembly operation can be realized on the roof, and then an overall roof system is formed, which can form a flat roof, an arc-shaped roof or a combination of the two. The installation method of the present invention can improve the installation accuracy, optimize the work efficiency, reduce the fixed installation time, shorten the construction progress, reduce resource consumption, and at the same time meet the requirements of different types of roof forms, realizing the applicable range of standardized flat modules and special-shaped modules and putting forward a sectional hoisting construction method for easy popularization and application;

[0042] Second, the upper cross-section of the fixed support of the present invention is larger than the lower cross-section, presenting a structure with a wider upper part and a narrower lower part. Moreover, the standing seam of the roof panel (i.e., the side edge) also has the same structure of a wider upper part and a narrower lower part. The two cooperate with each other, which can effectively resist the negative pressure effect caused by wind load (i.e., resist the uplift force). At the same time, an inclined triangular gusset plate is arranged at the small cross-section part of the lower part of the fixed support, effectively ensuring the compressive effect of the support. Before the lower roof panel is damaged, it can reinforce the lower roof panel, thus solving the weakness of the roof panel in resisting wind uplift in its inherent form, as well as problems such as poor installation accuracy and construction safety. The overall metal roof system can ensure the wind resistance quality under the synergistic action of the support and various reinforcement components, greatly improving the structural strength, stiffness and wind resistance performance of the roof panel.

[0043] Third, the present invention locks the two sides of two adjacent lower roof panels by setting a self-locking component. Among them, the outer clamping part can wrap the inner clamping part from the outside, and the protrusion of the inner clamping part engages with the outer clamping part, thus ensuring the self-locking between the inner clamping part and the outer clamping part. At the same time, a fixed support is also arranged on the inner sides of the inner and outer clamping parts. The fixed support can jack up and support the bottoms of the two sides of the lower roof panel, while the inner and outer clamping parts lock the lower roof panel from the outside to ensure the stability of the lower roof panel during installation and improve the wind resistance of the lower roof panel.

[0044] Fourth, a number of groups of positioning pin holes are equidistantly arranged on both sides of the fastening beam, and the module can slide on the fastening beam. At the same time, butterfly pin holes corresponding to the positioning pin holes are arranged on the module. Therefore, the fastening beam and the module can be fixed through the butterfly pin. The staff can move and adjust the module by controlling the installation of the butterfly pin, and the relative movement of the upper roof panel above the fastening beam can be realized. Furthermore, the connection between adjacent roof panels can be realized. It has high flexibility, strong practicability, and is easy to install, which can greatly accelerate the construction speed.

[0045] Fifth, the top of the module of the present invention can be slidably connected to the sliding rod. A serrated pin hole is arranged on the module, and a corresponding serrated slide bar is arranged on the sliding rod. Then the serrated pin passes through the serrated pin hole and can be clamped into the serrated slide bar, thus realizing the locking between the module and the sliding rod. At the same time, fine adjustment of the sliding rod can also be realized, avoiding the problem of locking between the module and the sliding rod, facilitating position adjustment, that is, adjusting the distance between the two fastening beams according to different lower roof panels so that it can be applicable to lower roof panels of different sizes, ensuring the efficient connection of subsequent roof panels. It has high flexibility, strong practicability, and is easy to install, which can greatly accelerate the construction speed.

[0046] VI. In the present invention, a thermal insulation and vapor barrier assembly is placed at the gaps between the fastening beam and the sliding rod. The thermal insulation and vapor barrier assembly includes a vapor barrier layer, a thermal insulation layer, and a waterproof layer from bottom to top. The fastening beam, the sliding rod, and the fixed support can support the upper roof panel, so that the thermal insulation and vapor barrier assembly is not directly compressed, ensuring the stability of the structure. When subjected to external pressure, the pressure is mainly borne by the support and the reinforcement assembly, improving the integrity;

[0047] VII. In response to the national development strategy of "dual carbon goals", the present invention uses the technology of photovoltaic energy storage, direct current, and flexible power. On the premise of meeting the national technical standards, the solar panels are fixed on the top of the self-locking fixture by using the nesting method to achieve "energy storage" and "power supply", so that the building's electricity demand changes from rigid to flexible.

Detailed implementation manners

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0062] Refer to Figure 1 、 Figure 2 and Figure 3 , for the prefabricated sliding and assembled roof, the roof of the present application can be a metal roof, etc., and there is no limitation on the material here, which can be determined according to the actual on-site installation situation; it is assembled by several groups of roof modules 1, Figure 1 The figure given is the graph after the complete assembly of three groups of roof modules 1, and Figure 2 is a partial disassembly diagram after the assembly of three groups of roof modules 1, which is convenient for observation, Figure 3 is a partial disassembly diagram after the assembly of the arc-shaped roof; it should be noted that the roof has a flat roof or an arc-shaped roof (as shown in Figure 2 ) or a combination of the two (that is, the top is an arc-shaped surface and the two sides are flat roofs), so several groups of roof modules 1 can be assembled into a flat roof, an arc-shaped roof, or a combination of the two, and the specific number of groups of roof modules 1 to be set depends on the actual size of the roof; during the assembly process, adjacent two groups of roof modules 1 are spliced through a connecting plate 2, and a bridge-shaped reinforcement member 3 is clamped above the connecting plate 2. It should be noted that multiple bridge-shaped reinforcement members 3 can be provided on the connecting plate 2 in the present application, which is determined according to different uplift forces and the on-site construction environment, and the specific number to be set is not limited here in the present application.

[0063] Refer toFigure 4 and Figure 5 , the roof module 1 includes support beams 11, lower roof panels 12, reinforcement components 13, upper roof panels 14, thermal insulation and vapor barrier components 15, mounting brackets 16, solar panels 17, and self-locking components 18. Among them, the support beams 11 are located at the bottom and are arranged at the bottom of the lower roof panels 12. Two to three support beams can be laid along the span direction of the lower roof panels 12, and they can be connected to the lower roof panels 12 by bolts or welding to ensure their stability; the reinforcement components 13 are installed on the top of the lower roof panels 12, and the thermal insulation and vapor barrier components 15 are located between the reinforcement components 13, which can play a role in thermal insulation and waterproofing for the lower roof panels 12; the upper roof panels 14 are locked by the self-locking components 18 above the reinforcement components 13, where the upper roof panels 14 are located on the top of the thermal insulation and vapor barrier components 15; two groups of parallelly distributed mounting brackets 16 are installed on the top of the self-locking components 18, and the solar panels 17 are installed on the top of the two groups of mounting brackets 16.

[0064] It should be noted that the thermal insulation and vapor barrier component 15 includes a vapor barrier layer, a thermal insulation layer, and a waterproof layer from bottom to top, providing vapor barrier, thermal insulation, and waterproof effects for the lower roof panel 12. (The thermal insulation and vapor barrier component 4 has the same structure as the waterproof reinforcement component 15, including a vapor barrier layer, a thermal insulation layer, and a waterproof layer from bottom to top); at the same time, the lower roof panel 12 can be made of color steel plate, and the upper roof panel 14 can be made of aluminum-magnesium-manganese plate, which is the best choice.

[0065] It should be noted that when assembling two adjacent roof modules 1, there are two installation methods. One is the splicing of two adjacent roof modules 1 along the roof span direction, and the other is the splicing of two adjacent roof modules 1 along the direction perpendicular to the roof span (as shown in Figure 1 and Figure 2 ), the connecting plate 2 has the same structure as the lower roof panel 12, and both ends of them are provided with edges and are in a corrugated shape in the middle;

[0066] When two adjacent sets of roof modules 1 are spliced along the roof span direction, the two lower roof panels 12 located below are overlapped up and down, that is, one lower roof panel 12 is placed on top of the other lower roof panel 12. Such a method helps with waterproofing and water diversion. A waterproof reinforcement component 4 is laid between the two sets of reinforcement components 13 in the middle. The two upper roof panels 14 located above are connected by a connecting plate 2. During installation, the two ends of the connecting plate 2 just overlap on the two adjacent upper roof panels 14, that is, stacked above the upper roof panels 14. The edges at both ends of the connecting plate 2 are also stacked up and down, and the overlapping part at both ends (i.e., the edges on both sides) is fixed by a self-locking component 18, so as to realize the splicing of the connecting plate 2 and the two sets of roof modules 1. The upper part of the overlapping part of the upper roof panel 14 and the connecting plate 2 is fixed by a bridge-shaped reinforcement member 3. The middle of the bridge-shaped reinforcement member 3 is arc-shaped and bent downward in the middle part. The two ends are buckled to the upper roof panel 14 or the connecting plate 2, providing a squeezing force for the upper roof panel 14 and the connecting plate 2, so that they can better withstand the wind uplift. It should be noted that multiple bridge-shaped reinforcement members 3 can be provided on the upper roof panel 14 in this application, depending on the different uplift forces and the on-site construction environment. The specific number of settings is not limited in this application. Before installing the connecting plate 2, a waterproof reinforcement component 4 needs to be laid at the bottom of the connecting plate 2 and above the lower roof panel 12 to improve the waterproof performance between the two sets of roof modules 1;

[0067] When two adjacent sets of roof modules 1 are spliced along the direction perpendicular to the roof span, the two lower roof panels 12 located below are also overlapped up and down (the same as the splicing method along the roof span direction above). The two sets of reinforcement components 13 in the middle are connected to ensure that the reinforcement components 13 of the entire roof are finally connected into one body. The two adjacent upper roof panels 14 located above are also stacked up and down, and then both overlapping parts are fixed by a self-locking component 18.

[0068] Refer to Figure 6, the reinforcement component 13 includes a fastening beam 131, sliding rods 132 and sliders 133. The fastening beam 131, sliding rods 132 and sliders 133 form a frame-like structure and are located at the middle position on the top of the lower roof panel 12. Among them, two groups of fastening beams 131 are provided and are laid parallel on the lower roof panel 12. A number of sliders 133 are installed on each group of fastening beams 131, and the sliders 133 can slide back and forth on the fastening beams 131. At the same time, the fastening beam 131 can be selected as an I-beam, which can also realize the upper and lower limits of the sliders 133 and the fastening beam 131. This process can be adjusted accordingly according to the needs of the staff. And a number of groups of sliding rods 132 are also provided. The two ends of each sliding rod 132 are detachably connected to the sliders 133 on the two groups of fastening beams 131. After installation, the sliding rods 132 and the fastening beams 131 are vertically distributed, and the several groups of sliding rods 132 are parallel to each other. It should be noted that the specific number of groups of sliders 133 provided on each group of fastening beams 131 depends on the on-site installation situation; similarly, the specific number of groups of sliding rods 132 also depends on the on-site installation situation.

[0069] Further, referring to Figure 6 and Figure 7 , a number of groups of positioning pin holes are equidistantly opened on both sides of the fastening beam 131. A steel groove 1333 is opened at the bottom of the slider 133. The steel groove 1333 is just slidably connected to the fastening beam 131. Butterfly pin holes 1331 are also opened on the left and right sides of the slider 133. The butterfly pin holes 1331 are structures with wide ends and narrow middle. This shape has good stability. Among them, the butterfly pin holes 1331 and the positioning pin holes on the fastening beam 131 are locked by butterfly pins 1332. During the assembly process, when the staff needs to adjust the distance between two adjacent sliding rods 132, the distance between the two sliders 133 on the fastening beam 131 can be adjusted, that is, the slider 133 is slid on the fastening beam 131 for adjustment. After adjusting to the required position, use the butterfly pin 1332 to lock the slider 133 and the fastening beam 131.

[0070] It should be noted that the side cross-section of the fastening beam 131 is in an I-shaped structure. Fastening grooves are opened at both ends of the fastening beam 131. The fastening grooves are half grooves of the butterfly pin 1332. When two fastening beams 131 are spliced, the ends of the two fastening beams 131 both extend into the slider 133. Then, the butterfly pin 1332 is inserted into the butterfly pin holes formed by the fastening grooves on the two fastening beams 131, and the fixation of the two fastening beams 131 can be realized (as Figure 6 It can be seen the fastening grooves at the ends of the fastening beam 131), so as to complete the connection and fixation between two adjacent fastening beams 131. Adopting this structure can greatly increase the stability between two adjacent fastening beams 131, further realize the connection between adjacent roof panels, with high flexibility, strong practicability and simple installation, which can greatly speed up the construction speed.

[0071] Further, referring to Figure 6 and Figure 7 , serrated slide bars 1321 are provided on the side walls at both ends of the sliding rod 132; a groove 1336 is formed at the top of the slider 133, where the groove 1336 is exactly slidably connected to the sliding rod 132, and serrated pin holes 1335 are formed on both the front and rear sides of the slider 133. The serrated pin holes 1335 and the serrated slide bars 1321 are locked by serrated pins 1334. During the assembly process, when the staff needs to adjust the distance between two adjacent sliders 133, the length of the sliding rod 132 between the fastening beams 131 can be adjusted, that is, the sliding rod 132 is slid within the slider 133 for adjustment. After adjusting to the required position, the slider 133 and the sliding rod 132 are locked using the serrated pin 1334.

[0072] Referring to Figure 8 and Figure 9 , the self-locking assembly 18 includes an outer clamping member 181 and an inner clamping member 182. The outer clamping member 181 includes an inner card slot, and the inner clamping member 182 includes a key adapted to the inner card slot. The key is inserted and cooperated with the inner card slot to enclose a support card slot. The top protrusion of the outer clamping member 181 wraps the inner clamping member 182 from above to achieve double clamping and self-locking, that is, not only the inner part of the outer clamping member 181 and the inner clamping member 182 is clamped by the inner card slot and the key, but also the outer part wraps the inner clamping member 182 through the outer clamping member 181, thereby realizing double self-locking for the self-locking assembly 18 and ensuring the stability of the self-locking assembly 18; card slots are formed on the inner sides of both the outer clamping member 181 and the inner clamping member 182, and a fixed support 183 is clamped in the support card slot formed by the two groups of card slots, that is, the outer contour of the fixed support 183 is adapted to the support card slot, and the two side edges of the upper roof panel 14 are limited between the support card slot and the fixed support 183. It should be noted that the support card slot is composed of upper and lower parts. The upper part is a fan-shaped groove, and the lower part is a rectangular groove (as Figure 9 shown).

[0073] Further, when the self-locking assembly 18 and the fixed support 183 lock the upper roof panel 4 and the connecting plate 2, the ends of the upper roof panel 14 and the connecting plate 2 can be wound around the outside of the fixed support 183. At this time, the fixed support 183 supports the upper roof panel 14 and the connecting plate 2 from the inside, and then the outer clamping member 181 and the inner clamping member 182 fix the upper roof panel 14, the connecting plate 2, and the fixed support 183 from both sides, that is, the outer clamping member 181 and the inner clamping member 182 fix the upper roof panel 14 and the connecting plate 2 from the outside; it should be noted here that two layers of connecting plates 2 or adjacent roof panels can be stacked on the top of the upper roof panel 14, and then locked by the self-locking assembly 18. This situation can be seen when two adjacent roof modules are spliced, as can be seen from Figure 1 this.

[0074] Refer to Figure 10 Figure 10 , the fixed support 183 includes a positioning horizontal plate 1832 and a limiting vertical rod 1831 vertically arranged on the positioning horizontal plate 1832; wherein the limiting vertical rod 1831 has a structure that is wider at the top and narrower at the bottom, and the inclined triangular gusset plates on both sides of its bottom are fixed to the positioning horizontal plate 1832. The top of the limiting vertical rod 1831 is an arc-shaped protrusion, and an inner concave section and a protrusion section are successively arranged downward along both sides of the arc-shaped protrusion, and this multi-section structure is integrally formed with the limiting vertical rod 1831.

[0075] Figure 11 Figure 11 shows another implementation manner of the fixed support 183, which also adopts a structure that is wider at the top and narrower at the bottom, and there are some differences at the top, and it can also be applied to the overall roof of the present invention.

[0076] As Figure 8 Figure 8 shown, the side edge of the upper roof panel 14 is adapted to the shape of the limiting vertical rod 1831, and its top is also an arc-shaped protrusion. An inner concave section and a protrusion section are successively arranged downward along both sides of the arc-shaped protrusion, and this multi-section structure is integrally formed with the upper roof panel 14.

[0077] Refer to Figure 12 Figure 12 , both sides of the solar panel 17 are embedded and installed in the nested plate 19. There are two groups of nested plates 19, which are respectively detachably installed above the two groups of mounting brackets 16. It should be noted that the outer side of the nested plate 19 is also fixed to the opening on the mounting bracket 16 by bolts through an L-shaped connecting plate, which increases the stability of the nested plate 19. Using the technology of photovoltaics-energy storage-direct current-soft connection, on the premise of meeting the national technical standards, the solar panels are fixed on the top of the self-locking assembly 18 by the nesting method to achieve "energy storage" and "power supply", so that the building's electricity demand changes from rigid to flexible.

[0078] The installation method of the prefabricated sliding and assembling roof of the present application:

[0079] Before assembly, ① First, before assembling the metal roof, it is necessary to set up an assembly platform on the ground in the span direction of the factory building. The height of the assembly platform needs to reach the height of the roof columns and meet the load requirements, and temporary assembly rails are set on the roof column beams of the factory building; ② The steel structure factory building is divided into areas for layout and sectional assembly. For larger structural spans, it is necessary to fix multiple roof panels on the assembly platform and then perform overall sliding installation; ③ Bolt holes are set on the roof column beams so that the roof modules can be slid to the designated positions for bolt fixation.

[0080] It should be noted that the bottom of the assembly platform is supported by several support columns, and the top of the platform can be slightly lower than the height of the roof columns. When installing, the staff transports the parts to the platform and then directly performs assembly above the assembly platform, which is convenient for placing the modules on the roof columns as a whole.

[0081] Method for assembling a single roof module of the present application:

[0082] During assembly, ① transport the prefabricated parts of the factory roof module 1 to the site, and assemble the single roof module 1 on the assembly platform; ② then install the lower roof panel 12 above the support beam 11, and install sliding shoes at the bottom of the support beam 11, and the sliding shoes can slide on the slide rail. Sequentially lay the fastening beam 131, slider 133 and sliding rod 132 above the lower roof panel 12, and lock the three of them. Subsequently, install the self-locking assembly 18 above the sliding rod 132, and fix the upper roof panel 14 using the self-locking assembly 18; place the thermal insulation and air barrier layer 15 at each gap between the fastening beam 131 and the sliding rod 132. The thermal insulation and air barrier layer 15 is, from bottom to top, a vapor barrier layer, a thermal insulation layer and a waterproof layer. Finally, install the solar panel 17 above the self-locking assembly 18;

[0083] ③ Slide the assembled single roof module 1 to the designated position on the roof using the slide rail on the roof column. Subsequently, use a jack to lift the roof module. The jack lifts the upper support beam 11 of it and slowly places the whole module on the roof column, and then perform overall fixation. Remove the sliding shoes, and after removing the corresponding segmented slide rails, fixedly connect the roof module 1 to the roof column; it should be noted here that if the span between the roof columns is very large, temporary steel columns can be set in the middle of the span direction. The temporary steel columns have the same height as the left and right roof columns, and slide rails are also placed on the temporary columns. The sliding steps are the same as before. After the two side unit roofs are simultaneously slid to the designated positions, then bolt the bottom support beams 11 on both sides. Then use a jack to remove some of the slide rails (the installation here is relatively flexible, and the staff can determine according to the actual on-site installation situation. The present application does not make a limit, and only gives some installation methods for selection);

[0084] ④ Subsequently, lay the waterproof reinforcement assembly 4 at the connection between two adjacent roof modules 1, and use the connecting plate 2 to connect the two roof modules 1 above the waterproof reinforcement assembly 4. Pay attention to the arrangement of the size and the staggered lap joint of the front and rear roof panels during assembly. If the span of the factory building is too large, multiple modules are installed and then overall sliding installation is carried out. At the same time, the load stability of the assembly platform needs to be checked. When the span of the factory building is too large, the temporary steel columns described in step ④ are used for assistance, and the steps refer to the description of the temporary steel columns above;

[0085] ⑤ Sequentially perform the above steps, assemble the whole roof in blocks, slide it to the designated position, and perform fine adjustment of the roof through the fine adjustment system between the fastening beam 131, sliding rod 132 and slider 133 within the roof system itself to achieve the overall roof effect.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
