The dome structure includes an edge truss, a corner unit connected to one side of the edge truss, a spaced-apart partition truss band connected to the length of the edge truss, a partition unit connected between the partition truss bands, and an arc-shaped truss connected to the middle of the length of the edge truss. Supporting steel columns are connected at intervals below the dome structure. The above invention has the problems of long construction and installation time, complex top connection mechanism, and affecting the lighting inside the venue. Summary of the Invention

[0004] In view of this, the construction method and connection mechanism of the curved roof provided by the present invention can solve the problems of long construction and installation time, complex top connection mechanism, and impact on indoor lighting of the venue.

[0005] This invention is implemented as follows:

[0006] This invention provides a construction method for an arched roof, comprising the following steps:

[0007] S10: Mark and measure the construction area, drill holes according to the marked locations, place steel cages in the holes and pour concrete to obtain the concrete pier support structure.

[0008] S20: Connecting support columns to a concrete pier support structure with fixing bolts and constructing a steel truss between the support columns;

[0009] S30: Hoist the curved top beam on the steel truss and fit the plate connecting kit on the curved top beam;

[0010] S40: Adjust the connection angle of the sheet metal connection kit on the curved top beam, and fix the PVC baffle on the sheet metal connection kit with bolts;

[0011] S50: Install sealing connection components along the groove at the edge connection end of the PVC baffle.

[0012] Based on the above technical solution, the construction method of the arched roof of the present invention can be further improved as follows:

[0013] The specific steps for marking and measuring the construction area, drilling holes according to the marked locations, placing reinforcing cages in the holes, and pouring concrete to obtain the concrete pier support structure are as follows: The construction area is measured and marked using a total station according to the design dimensions in the drawings. The points requiring drilling and grouting are marked in segments according to the marked locations. A geological drilling rig is guided to the site. Holes are drilled in the ground according to the marked locations. The width and depth of the holes are set according to the diameter and height of the support column. After cleaning the outer surface of the pile hole, a reinforcing cage for grouting is placed inside. Connectors are fixed to the top of the reinforcing cage by welding. After the connectors are embedded, concrete is poured into the holes sequentially. After the concrete dries completely, the concrete pier support structure is obtained.

[0014] Furthermore, the specific steps for connecting the support columns to the concrete pier support structure with fixing bolts and constructing a steel truss between the support columns are as follows: guide the crane into the site, use the boom to lift the support columns, connect and fix the bottom of the support columns to the top of the concrete pier support structure with bolts, after all the support columns are fixed, lift the steel truss between the support columns on both sides with the crane, align the flanges at both ends of the steel truss with the flange connectors at the top of the support columns on both sides in sequence, and fix the steel truss between the support columns on both sides with bolts to complete the construction of the steel truss.

[0015] Furthermore, the specific steps for hoisting the arc-shaped top beam on the steel truss and fitting the plate connecting kit on the arc-shaped top beam are as follows: the arc-shaped top beam is hoisted by a crane, wherein connecting columns of different heights are sequentially set at the bottom of the arc-shaped top beam so that the bottom of the connecting columns contacts the top of the steel truss and is welded and fixed using an electric welding machine. After each arc-shaped top beam is welded and fixed to the steel truss in sequence, the plate connecting kit is fitted and installed on the arc-shaped top beam.

[0016] Furthermore, the plate connecting kit includes an upper sleeve and a lower sleeve. A movable connecting assembly is provided at one end of the upper sleeve and the lower sleeve, and a fixing plate is provided at the other end of the upper sleeve and the lower sleeve. The fixing plate has threaded holes. The plate connecting kit is fixedly installed on the arc-shaped top beam via the fixing plate and bolts. A connecting platform is fixedly welded to the top of the upper sleeve, and hinge components are fixedly welded to both sides of the top of the connecting platform. A mounting base is fixedly welded to the top of the hinge components, and mounting support plates are fixedly connected to both ends of the mounting base via bolts. The mounting support plates include an upper connecting support plate and a lower connecting support plate.

[0017] Furthermore, the hinge kit includes a hinge chuck, the bottom of which is fixedly welded to the connecting platform. A through hole is provided on the hinge chuck, and a rotating shaft is rotatably disposed in the through hole. Hinges are fixedly welded to both ends of the rotating shaft, and the hinge sleeves are fixedly welded to the bottom of the mounting base.

[0018] Furthermore, the mounting base has two sets of screw holes, and a first adjusting bolt and a second adjusting bolt are respectively installed in the screw holes. The first adjusting bolt and the second adjusting bolt are used to adjust the connection angle between the mounting base and the connecting platform.

[0019] Furthermore, the specific steps for adjusting the connection angle of the panel connecting kit on the arc-shaped top beam and fixing the PVC baffle on the panel connecting kit with bolts are as follows: The lower ends of the first adjusting bolt and the second adjusting bolt on the panel connecting kit in the middle of the arc-shaped top beam are of the same length at the bottom of the mounting base. For the panel connecting kit on the left side, the position of the first adjusting bolt needs to be adjusted upwards, and then the second adjusting bolt is tightened to tilt the mounting base to the left on the connecting platform. For the panel connecting kit on the right side, the position of the second adjusting bolt needs to be adjusted upwards, and then the first adjusting bolt is tightened to tilt the mounting base to the right on the connecting platform. The tilt angle is adjusted according to the connection angle of the PVC baffle. After adjusting the angle of the panel connecting kit, the mounting hole at one end of the bottom of the PVC baffle is aligned with the lower connecting support plate on one set of panel connecting kits, and the mounting hole at the other end of the bottom of the PVC baffle is aligned with the upper connecting support plate on the adjacent set of panel connecting kits, and then fixed with bolts.

[0020] Furthermore, the specific steps for installing the sealing connection component along the groove at the edge connection end of the PVC baffle are as follows: insert a short sealing connection component along the groove on both sides of the PVC baffle in the gap of the longitudinal connection between the PVC baffles on the whole arc-shaped top beam, and insert a long sealing connection component along the groove in the gap of the transverse connection between the PVC baffles on two adjacent arc-shaped top beams.

[0021] Furthermore, the sealing connection component includes the long sealing connection component and the short sealing connection component. The sealing connection component is a hard rubber structure with a cross-shaped cross section. The sealing connection component has protrusions on both sides of the cross section. The protrusions are used to guide rainwater during rainy days. The sealing connection component is adapted to the groove on the PVC baffle.

[0022] Compared with existing technologies, the beneficial effects of the construction method and connection mechanism for an arched roof provided by this invention are as follows: The concrete pier support structure increases the contact area between the support column and the ground, making the connection between the support column and the ground tighter, thereby enhancing the stability of the arched roof. Furthermore, the concrete pier support structure effectively prevents the support column from tilting or collapsing, thus avoiding safety accidents. Secondly, since the support column is in contact with the ground and is susceptible to rainwater erosion, the reinforcement method using concrete piers can extend the service life of the arched roof. Finally, the steel truss can be fixed and installed using flanges and bolts. To improve the overall stability and load-bearing capacity of the steel truss, thereby reducing the probability of accidents; the indirect fixing method using flanges effectively reduces the risk of corrosion and wear caused by direct exposure to the climate; in addition, flange fixing installation allows for more convenient and faster installation and maintenance; the use of plate connection kits for fixing PVC baffles, with adjustable angles to create an arched roof for rainwater drainage; the PVC baffles enhance the light transmission inside the building, and the sealing connection components effectively seal the gaps between the PVC baffles, making the connection tighter. This not only improves air tightness but also effectively prevents external rainwater intrusion, thereby reducing contaminants in the gaps, maintaining indoor air quality and humidity, and extending the service life of the PVC baffles.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] like Figure 1 The diagram shown is a construction flowchart of a method for constructing an arched roof according to the present invention, including the following steps:

[0037] S10: Mark and measure the construction area, drill holes according to the marked locations, place steel cages in the holes and pour concrete to obtain the concrete pier support structure.

[0038] S20: Connecting support columns to a concrete pier support structure with fixing bolts and constructing a steel truss between the support columns;

[0039] S30: Hoist the arc-shaped top beam on the steel truss, and fit the plate connecting kit 10 on the arc-shaped top beam;

[0040] S40: Adjust the connection angle of the plate connecting kit 10 on the arc-shaped top beam, and fix the PVC baffle 11 on the plate connecting kit 10 with bolts;

[0041] S50: Install a sealing connection component along the slot at the edge connection end of the PVC baffle 11.

[0042] It should be noted that the purpose of the cast-in-place concrete pier support structure is to increase the contact area between the support column and the ground, making the connection between the support column and the ground tighter, thereby enhancing the stability of the arched roof. In addition, the cast-in-place concrete pier support structure can effectively prevent the support column from tilting or collapsing, thus avoiding safety accidents. Furthermore, since the support column is in contact with the ground, it is susceptible to rainwater erosion. Strengthening it with cast-in-place piers can extend the service life of the arched roof.

[0043] The specific steps of marking and measuring the construction area, drilling holes according to the marked locations, placing reinforcing cages in the holes, and pouring concrete to obtain the concrete pier support structure are as follows: The construction area is measured and marked using a total station according to the design dimensions in the drawings. The points requiring drilling and grouting are marked in segments according to the marked locations. A geological drilling rig is guided to the site. Holes are drilled in the ground according to the marked locations. The width and depth of the holes are set according to the diameter and height of the support column. After cleaning the outer surface of the pile hole, a reinforcing cage for grouting is placed inside. Connectors are fixed to the top of the reinforcing cage by welding. After the connectors are embedded, concrete is poured into the holes sequentially. After the concrete dries completely, the concrete pier support structure is obtained.

[0044] It should be noted that a total station is a high-precision, multi-functional modern surveying instrument capable of simultaneously measuring angles and distances. Total stations are widely used in civil engineering, mining exploration, building surveying, road and flight path surveying, and are particularly suitable for surveying tasks requiring high precision and efficiency. They offer advantages such as fast measurement speed, large data storage capacity, and high measurement accuracy. The total station used in this invention is a common model used in the construction industry.

[0045] like Figure 2 As shown, in the above technical solution, the specific steps for connecting the support columns to the concrete pier support structure with fixing bolts and constructing a steel truss between the support columns are as follows: guide the crane to the site, use the crane arm to lift the support columns, connect and fix the bottom of the support columns to the top of the concrete pier support structure with bolts, after all the support columns are fixed, lift the steel truss between the support columns on both sides with the crane, align the flanges at both ends of the steel truss with the flange connectors at the top of the support columns on both sides in sequence, and fix the steel truss between the support columns on both sides with bolts to complete the construction of the steel truss.

[0046] It's important to note that using flanges and bolts to secure the steel truss improves its overall stability and load-bearing capacity, thus reducing the probability of accidents. The indirect fixing method with flanges effectively reduces the risk of corrosion and wear from direct exposure to the environment. Furthermore, flange installation allows for easier and faster installation and maintenance, eliminating the need for welding or nailing as required by traditional steel frame connections. This installation method enables quicker and more intuitive assembly and installation of the steel truss on the ground, significantly reducing installation time and resulting in substantial savings in both project duration and cost.

[0047] Furthermore, in the above technical solution, the specific steps for hoisting the arc-shaped top beam on the steel truss and installing the plate connecting kit 10 on the arc-shaped top beam are as follows: the arc-shaped top beam is hoisted by a crane, wherein connecting columns of different heights are sequentially set at the bottom of the arc-shaped top beam so that the bottom of the connecting columns contacts the top of the steel truss and is welded and fixed using an electric welding machine. After each arc-shaped top beam is welded and fixed to the steel truss in sequence, the plate connecting kit 10 is installed on the arc-shaped top beam.

[0048] like Figure 3-5As shown, this invention provides a connecting component for an arched roof. In the above technical solution, the panel connecting kit 10 includes an upper sleeve 12 and a lower sleeve 13. One end of the upper sleeve 12 and the lower sleeve 13 is provided with a movable connecting component, and the other end of the upper sleeve 12 and the lower sleeve 13 is provided with a fixing plate 14. The fixing plate 14 is provided with a threaded hole. The panel connecting kit 10 is fixedly installed on the arched roof beam by the fixing plate 14 and bolts. A connecting platform 15 is fixedly welded to the top of the upper sleeve 12. Hinged components 16 are fixedly welded to both sides of the top of the connecting platform 15. A mounting base 17 is fixedly welded to the top of the hinged components 16. Mounting support plates 18 are fixedly connected to both ends of the mounting base 17 by bolts. The mounting support plate 18 includes an upper connecting support plate 23 and a lower connecting support plate 24.

[0049] Preferably, the number of connecting columns on one of the arc-shaped top beams is 8, and the number of plate connecting kits 10 is 9 sets.

[0050] It should be noted that by setting up the panel connecting kit 10 for fixing and installing the PVC baffle 11, the light transmission intensity inside the building is enhanced, and the angle can be adjusted to construct an arc-shaped roof, which facilitates the diversion of rainwater.

[0051] Furthermore, in the above technical solution, the hinge kit 16 includes a hinge chuck 19, the bottom of the hinge chuck 19 is fixedly welded to the connecting platform 15, a through hole is provided on the hinge chuck 19, a rotating shaft is rotatably arranged in the through hole, and hinge sleeves 20 are fixedly welded to both ends of the rotating shaft, and the hinge sleeves 20 are fixedly welded to the bottom of the mounting base 17.

[0052] Furthermore, in the above technical solution, the mounting base 17 is provided with two sets of screw holes, and a first adjusting bolt 21 and a second adjusting bolt 22 are respectively provided in the screw holes. The first adjusting bolt 21 and the second adjusting bolt 22 are used to adjust the connection angle between the mounting base 17 and the connecting platform 15.

[0053] Furthermore, in the above technical solution, the specific steps for adjusting the connection angle of the plate connecting kit 10 on the arc-shaped top beam and fixing the PVC baffle 11 to the plate connecting kit 10 with bolts are as follows: the lower ends of the first adjusting bolt 21 and the second adjusting bolt 22 on the plate connecting kit 10 in the middle of the arc-shaped top beam are of the same length at the bottom of the mounting base 17. For the plate connecting kit 10 on the left side, the position of the first adjusting bolt 21 needs to be adjusted upwards, and then the second adjusting bolt 22 is tightened, so that the mounting base 17 tilts to the left on the connecting platform 15. For the plate connecting kit 10 on the right side, the position of the first adjusting bolt 21 needs to be adjusted upwards, and then the second adjusting bolt 22 is tightened, so that the mounting base 17 tilts to the left on the connecting platform 15. For the material connecting kit 10, the position of the second adjusting bolt 22 needs to be adjusted upwards, and then the first adjusting bolt 21 is tightened to make the mounting base 17 tilt to the right on the connecting platform 15. The tilt angle is adjusted according to the connection angle of the PVC baffle 11. After the angle of the material connecting kit 10 is adjusted, the mounting hole at one end of the bottom of the PVC baffle 11 is aligned with the lower connecting support plate 24 on one set of material connecting kits 10, and the mounting hole at the other end of the bottom of the PVC baffle 11 is aligned with the upper connecting support plate 23 on the adjacent set of material connecting kits 10. The kit is then fixed in place with bolts.

[0054] It should be noted that after the PVC baffles 11 are installed on one of the curved top beams, short sealing connection components need to be inserted into the longitudinal connection gaps between the PVC baffles 11 along the slots. Then, the PVC baffles 11 on adjacent curved top beams are installed. Then, long sealing connection components are inserted into the transverse connection gaps between the PVC baffles 11 on the two curved top beams along the slots. The long sealing connection components are inserted as a whole piece.

[0055] Furthermore, in the above technical solution, the specific steps for installing the sealing connection component along the slot at the edge connection end of the PVC baffle 11 are as follows: short sealing connection components are inserted along the slots on both sides of the PVC baffle 11 in the longitudinal connection gap between the PVC baffles 11 on the entire arc-shaped top beam; long sealing connection components are inserted along the slots in the transverse connection gap between the PVC baffles 11 on two adjacent arc-shaped top beams.

[0056] Furthermore, in the above technical solution, the sealing connection component includes a long sealing connection component and a short sealing connection component. The sealing connection component is a hard rubber structure with a cross-shaped cross section. The sealing connection component has protrusions 25 on both sides of the cross section. The protrusions 25 are used to guide rainwater during rainy days. The sealing connection component is adapted to the groove on the PVC baffle 11.

[0057] By setting the protrusion 25, it is possible to prevent external rainwater from seeping into the room through the grooves on both sides of the PVC baffle 11, thus preventing water leakage.

[0058] It should be noted that the purpose of installing the sealing connection components is to effectively seal the gaps between the PVC baffles 11, making the connection tighter. This not only improves air tightness but also effectively prevents the intrusion of external rainwater, thereby reducing pollutants in the gaps, maintaining indoor air quality and humidity, and extending the service life of the PVC baffles 11.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
