Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a double-sloped roof envelope structure with ventilators and its construction method. Background Technology

[0002] In recent years, considering time, labor, and material costs, as well as the structural safety and stability of buildings, construction methods have moved beyond traditional brick and tile structures and begun to utilize a large amount of corrosion-resistant metal. Metal roofing is the most common application of metal in construction. During construction, after the exterior walls and roof are completed, a roofing or wall cladding system is typically installed to improve the building's waterproofing and insulation. Because some power plant workshops have rooftop ventilators, the waterproofing and insulation requirements for the cladding structure are even higher. However, existing double-sloped roof cladding structures with ventilators still present some problems during use.

[0003] For example, Chinese Patent Publication No. CN 116104240 A discloses a double-sloped roof enclosure structure with ventilators and its construction method. The structure includes a roof steel truss structure with several purlins, multi-ribbed plates on the purlins, waterproof and thermal insulation boards on the multi-ribbed plates, and a roof panel on the waterproof and thermal insulation board. A ridge connecting structure is provided at the ridge, and a gutter is provided at the eaves. One end of the gutter is attached to a concrete parapet wall, and the other end is attached to a purlin. Roof ventilators are also installed on the purlins, with their bottoms mounted on ventilator supports. One end of the roof ventilator passes through the multi-ribbed plates, waterproof and thermal insulation board, and roof panel to connect with the outside. This enclosure structure provides thermal insulation and waterproofing, and seals the connections between the roof ventilator and the roof steel truss structure, the ridge, the eaves and the gutter, and the gutter and the concrete wall, resulting in good sealing performance, a simple structure, and strong practicality.

[0004] The sealing structure at the connection between the roof panel and the ridge of the above-mentioned double-sloped roof enclosure structure with ventilator is too complicated. Although it has a good sealing structure, it is complicated to install and difficult to maintain. It is fixed by multiple bolts, and the bolt holes are prone to water leakage, which affects the sealing effect. Therefore, this application provides a double-sloped roof enclosure structure with ventilator and its construction method to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a double-sloped roof enclosure structure with ventilators and its construction method, which can effectively solve the problems of complex structure and poor sealing effect of existing double-sloped roof enclosure structures with ventilators mentioned in the background art, and achieve the purpose of simplifying the structure and improving the sealing effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a double-sloped roof enclosure structure with a ventilator, comprising two sets of interconnected roof panels, a ridge installed between the two sets of roof panels, a first connecting unit for sealing the roof panels and the ridge between the roof panels and the ridge, a second connecting unit for sealing the two ridges between adjacent ridges, and a third connecting unit for sealing the two ridges between adjacent ridges;

[0007] The first connecting unit includes a connecting plate disposed on one side of the roof panel. The connecting plate is provided with a first concave portion. A first vertical plate is provided on one side of the first concave portion. Both sides of the ridge are provided with second concave portions that are bent inward. A second vertical plate is provided on one side of the second concave portion. The first vertical plate and the second vertical plate abut against each other. A sealing strip is provided between the first vertical plate and the second vertical plate.

[0008] Preferably, a plug is fixedly connected to the end of the ridge, and the ridge and the plug are sealed together by a sealing strip.

[0009] Preferably, both the roof panel and the ridge are provided with mounting holes, and the roof panel and the ridge are fixedly connected by bolts.

[0010] Preferably, the second connecting unit includes guide rails disposed on both sides of the roof panel, the guide rails between two adjacent roof panels abutting each other, and the same connecting strip is slidably connected on the two guide rails between two adjacent roof panels for sealing connection of the two adjacent roof panels.

[0011] Preferably, the third connecting unit includes an anti-detachment strip fixedly connected to the end of the ridge, a connecting block is provided between two adjacent anti-detachment strips, and one end of the connecting block is inserted into one of the ridges, and the other end of the connecting block is inserted into the other adjacent ridge.

[0012] Preferably, the connecting block is provided with a limiting unit for connecting the second connecting unit and the third connecting unit. The limiting unit includes a positioning groove formed at the end of the connecting strip. A shaft is inserted into the connecting block, and a block is sleeved on the shaft. The bottom end of the block is inserted into the positioning groove. A first connecting rod is rotatably connected to the top end of the block. A second connecting rod is rotatably connected to the first connecting rod. A rotating block is rotatably connected inside the connecting block, and one end of the second connecting rod is rotatably connected to the rotating block.

[0013] A construction method for a double-sloped roof enclosure structure with a ventilator includes step one: ridge splicing, aligning the ends of two adjacent ridges, inserting connecting blocks into the ends of the two ridges until both ends of the connecting blocks abut against the anti-detachment strips at the ends of the two ridges, at which point the anti-detachment strips are deeply embedded in the connecting blocks, and the connecting blocks cover the connection gap between the anti-detachment strips and the connecting blocks.

[0014] Step 2: Splicing the ridge and roof panels. After the ridge is spliced, align the first vertical plate on each pair of roof panels with the second vertical plate on the ridge. At this time, clamp the sealing strip between the first and second vertical plates. The mounting holes on the roof panels and the ridge are now aligned. Then, fix them with bolts. After that, install multiple pairs of roof panels onto the ridge in sequence to complete the splicing of the ridge and roof panels.

[0015] Step 3: Roof panel splicing. After completing the splicing of the ridge and roof panels, the guide rails between adjacent roof panels will be aligned and abutting. Then, push the connecting strip to slide it onto the guide rail, thus connecting the adjacent roof panels.

[0016] Preferably, the method further includes installing end caps at the ends of the ridges forming the double-sloped roof, wherein the ridges and the end caps are connected by a sealing fixation.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, a sealed connection structure is formed by setting up a connecting plate, a first recess, a first vertical plate, a second recess, a second vertical plate, mounting holes, and a sealing strip, replacing the existing bolt connection structure. This reduces the number of holes to be made in the metal plate, improves service life, and the cooperation between the first and second recesses, as well as the cooperation between the first and second vertical plates, forms a structure that prevents rainwater from splashing onto the sealing strip. This prevents rainwater accumulation, reduces the risk of moisture on the sealing strip, improves the sealing effect, and makes the solution highly practical.

[0019] By setting guide rails, connecting strips, anti-detachment strips, and connecting blocks, a sealed connection is formed between roof panels and between roof ridges. The second and third connecting units are fixedly connected by positioning grooves, insert shafts, insert blocks, first connecting rods, second connecting rods, and rotating blocks, which further improves the connection stability. Furthermore, the existing bolt connection structure is replaced by a limiting unit, which ensures connection stability while reducing openings and improving the sealing effect.

[0037] like Figure 1-6 As shown, an embodiment of the present invention provides a double-sloped roof enclosure structure with a ventilator, including two sets of interconnected roof panels 1, a ridge 2 installed between the two sets of roof panels 1, a first connecting unit 4 for sealing the roof panels 1 and the ridge 2 between the roof panels 1 and the ridge 2, a second connecting unit 5 for sealing the two adjacent ridges 2 between adjacent ridges 2, and a third connecting unit 6 for sealing the two adjacent ridges 2. Through the cooperative use of the first connecting unit 4, the second connecting unit 5 and the third connecting unit 6, a sealed connection structure for the double-sloped roof is formed, minimizing the use of bolts, reducing the number of perforations, improving the mechanical properties of the metal plate structure, ensuring the sealing effect, facilitating disassembly and assembly, and having high practicality.

[0038] like Figure 2-3 As shown, the first connecting unit 4 includes a connecting plate 7 disposed on one side of the roof panel 1. The connecting plate 7 has a first recess 8, and a first vertical plate 9 is disposed on one side of the first recess 8. Both sides of the ridge 2 have inwardly bent second recesses 10, and a second vertical plate 11 is disposed on one side of the second recess 10. The first vertical plate 9 and the second vertical plate 11 abut against each other. A sealing strip 13 is disposed between the first vertical plate 9 and the second vertical plate 11. A plug 3 is fixedly connected to the end of the ridge 2, and the ridge 2 and the plug 3 are sealed together by a sealing strip. Mounting holes 12 are provided on both the roof panel 1 and the ridge 2. The sealing strip 13 is fixedly connected by bolts. By aligning the first vertical plate 9 on the roof panel 1 with the second vertical plate 11 on the ridge 2 and clamping the sealing strip 13 in the middle, the mounting holes 12 are aligned. The connection is then fixed by bolts. In use, the cooperation of the first concave part 8 and the second concave part 10, as well as the cooperation of the first vertical plate 9 and the second vertical plate 11, forms a structure that prevents rainwater from splashing onto the sealing strip 13. The sealing strip 13 is suspended downwards, which prevents rainwater accumulation, reduces the risk of moisture on the sealing strip 13, and improves the service life of the sealing strip 13. It replaces the existing bolt connection structure, improves the sealing effect, and is highly practical.

[0039] like Figure 3 and Figure 5As shown, the second connecting unit 5 includes guide rails 14 disposed on both sides of the roof panel 1. The guide rails 14 between two adjacent roof panels 1 abut against each other. The same connecting strip 15 is slidably connected to the two guide rails 14 between two adjacent roof panels 1 for sealing connection of the two adjacent roof panels 1. After the two adjacent guide rails 14 are aligned, they are slidably spliced ​​by the connecting strip 15. The connecting strip 15 is also provided with sealant to improve the sealing effect between the two guide rails 14. The connecting strip 15 covers the gap between the two guide rails 14 from above to prevent rainwater from splashing into the gap and improve the sealing effect.

[0040] like Figure 4-5 As shown, the third connecting unit 6 includes an anti-detachment strip 16 fixedly connected to the end of the ridge 2. A connecting block 17 is provided between two adjacent anti-detachment strips 16. One end of the connecting block 17 is inserted into one of the ridges 2, and the other end of the connecting block 17 is inserted into the other adjacent ridge 2. The two ridges 2 are connected by the connecting block 17. When connected, the anti-detachment strip 16 is embedded in the connecting block 17. The connecting block 17 covers the gap at the connection position, further improving the sealing and moisture-proof effect.

[0041] like Figure 5-6 As shown, the connecting block 17 is provided with a limiting unit for connecting the second connecting unit 5 and the third connecting unit 6. The limiting unit includes a positioning groove 18 formed at the end of the connecting strip 15. A shaft 19 is inserted into the connecting block 17, and a block 20 is sleeved on the shaft 19. The bottom end of the block 20 is inserted into the positioning groove 18. A first connecting rod 21 is rotatably connected to the top end of the block 20. A second connecting rod 22 is rotatably connected to the first connecting rod 21. A rotating block 23 is rotatably connected inside the connecting block 17, and one end of the second connecting rod 22 rotates... The connecting rod 15 is mounted on the guide rail 14 after the connecting block 17 is installed. At the same time, one end of the connecting rod 15 is inserted into the connecting block 17. Then, the rotating block 23 is rotated, which drives the second connecting rod 22 to rotate, and then drives the first connecting rod 21 to move. Under the guidance of the insert shaft 19, the insert block 20 is driven to insert and abut against the positioning groove 18. At this time, the rotating block 23 is completely rotated into the connecting block 17, thus fixing the end of the connecting rod 15. The structure is simple, the connection stability is good, and it is easy to disassemble and assemble.

[0042] like Figure 1-7As shown, a construction method for a double-sloped roof enclosure structure with a ventilator is characterized by the following steps: ridge splicing, aligning the ends of two adjacent ridges 2, inserting connecting blocks 17 into the ends of the two ridges 2 until both ends of the connecting blocks 17 abut against the anti-detachment strips 16 at the ends of the two ridges 2. At this point, the anti-detachment strips 16 are deeply embedded in the connecting blocks 17, and the connecting blocks 17 cover the connection gap between the anti-detachment strips 16 and the connecting blocks 17, forming a better sealing effect, reducing rainwater ingress, and improving practicality.

[0043] Step 2: Splicing the ridge and roof panels. After the ridge 2 is spliced, align the first vertical plate 9 on each pair of roof panels 1 with the second vertical plate 11 on the ridge 2. At this time, clamp the sealing strip 13 between the first vertical plate 9 and the second vertical plate 11. The mounting holes 12 on the roof panels 1 and the ridge 2 are now aligned. Then, fix them with bolts. After that, install multiple pairs of roof panels 1 onto the ridge 2 in sequence to complete the splicing of the ridge 2 and roof panels 1. The bolt structure is hidden inside the roof and will not be affected by rainwater, which improves the service life of the connection structure and the sealing effect.

[0044] Step 3: Roof panel splicing. After the splicing of ridge 2 and roof panel 1 is completed, the guide rails 14 between adjacent roof panels 1 are just aligned. Then, push the connecting strip 15 to slide and splice it on the guide rail 14 to achieve the connection between adjacent roof panels 1. The connecting strip 15 is equipped with a sealing strip inside. After it is installed on the guide rail 14, it can improve the sealing effect. After the roof panels 1 are spliced, the end caps 3 are installed at the ends of the ridge 2 that form the double-sloped roof. The ridge 2 and the end caps 3 are connected by sealing. Then, drive the limiting unit to snap the connecting strip 15 into the connecting block 17 to further improve the stability of each connection structure.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
