[0028] The present application is further described in detail below with reference to FIGS. 1-11.

[0029] The present application discloses a modular courtyard pergola and an assembly method.Embodiment 1:

[0030] Referring to FIGS. 1 and 2, a modular courtyard pergola includes a plurality of columns 1 which are vertically erected, a crossbeam 2 which extends horizontally between adjacent columns 1, a connecting assembly configured for connecting the column 1 and the crossbeam 2, a screen assembly 4 on the crossbeam 2, a cover plate 5 for covering the connecting assembly, and a base 6 configured for supporting.

[0031] The column 1 has a full-length rectangular cross-section with open ends. The column 1 is integrally formed with an inner reinforcing frame 11 in its length direction, and the inner reinforcing frame 11 has a #-shaped cross-section. A top of the column 1 is milled to form a socket end 12. The socket end 12 is a # - shaped inner hole of the inner reinforcing frame 11, which means that the cross-section of the socket end 12 is rectangular. In order to facilitate connection between the column 1 and the base 6 with the connecting assembly, the inner reinforcing frame 11 is integrally formed with a tube socket 13. The tube socket 13 includes a first tube socket 131 in the # - shaped inner hole and a second tube socket 132 at four corners of #- shaped inner hole. The first tube socket 131 and the second tube socket 132 are both arc-shaped tubes with one open end.

[0032] The crossbeam 2 is a rectangular pipe, two ends thereof are both formed with inclined sockets 21 which can be horizontally inserted into the socket ends 12 respectively. An inclination angle of the inclined socket 21 is 45° . The crossbeam 2 is provided with a top plate 22, a transverse reinforcement plate 23, and a bottom plate 24 spaced from top to bottom along a height direction. Both ends of the bottom plate 24 and ends of the top plate 22 are flush with the inclined sockets 21 respectively, and a length of the transverse reinforcement plate 23 is smaller than that of the bottom plate 24. A first positioning groove 25 is formed between the transverse reinforcement plate 23 and the bottom plate 24. A second positioning groove 29 is formed between the transverse reinforcement plate 23 and the top plate 22.

[0033] Referring to FIGS. 2 and 3, the connecting assembly includes a lower connector 31, an upper connector 32, and locking elements 33. In this embodiment, the locking elements 33 are self-tapping screws 331 and countersunk screws 332. The lower connector 31 is sleeved on the socket end 12, which includes a sleeve part 311 and first extension parts 312 which are provided on adjacent sides of the sleeve part 311. The sleeve part 311 has a rectangular inner hole that is adapted to the socket end 12. The lower connector 31 and the socket end 12 are fixedly connected by the countersunk screws 332, the countersunk screws 332 pass through the sleeve part 311 and the socket end 12 along a horizontal direction. There is a seal gap 34 between a bottom wall of the lower connector 31 and the column 1.

[0034] Extension directions of the two first extension parts 312 are perpendicular to each other. Each first extension 312 is integrally formed with first sockets 313 on opposite inner side walls. A cross-section of the first socket 313 is an arc-shaped ring, a curvature of the arc-shaped ring is greater than 180° . An inner wall of the first socket 313 is vertically provided with convex parts 3131 along a circumferential direction.

[0035] After fixing the lower connector 31 with the socket end 12, the crossbeam 2 is installed. When horizontally inserting the crossbeam, the bottom plate 24 is inserted into the seal gap 34, and the two first extension parts 312 are respectively inserted into the first positioning grooves 25 between the transverse reinforcement plates 23 and the bottom plates 24. The transverse reinforcement plate 23 has a first through hole 231 corresponding to the first socket 313, and the top plate 22 has a strip-shaped through hole 221 corresponding to the first through hole. The first through hole 231 is adapted to the locking element 33, and a size of the strip-shaped through hole 221 is larger than that of the first through hole 231.

[0036] Referring to FIGS. 4, 5 and 6, the upper connector 32 is configured to insert into a joint of adjacent crossbeams 2, and it includes a positioning part 321 and second extension parts 322 on two adjacent side walls of the positioning part 321. A size of the upper connector 32 is the same as that of the lower connector 31, and a difference between the upper connector 32 and the lower connector 31 is that the upper connector is provided with a rectangular connecting frame 323 inside the positioning part 321. The connecting frame 323 is integrally formed or detachably connected with the upper connector 32. In this embodiment, the connecting frame 323 and the upper connector 32 are fixedly connected by the countersunk screws 332.

[0037] Inner walls of the connecting frame 323 are all provided with second sockets 3231 that are structurally consistent with the first tube socket 131. The second socket 3231 corresponds one-to-one with the first tube socket 131. The top plate 22 has second through holes 222 that correspond one-to-one with the first sockets 313. The top plate 22 is lower than a top surface of the crossbeam 2, so as to form a through grooves 26 through the top plate 22 and two side walls of the crossbeam 2 for positioning and inserting the upper connector 32.

[0038] The upper connector 32 can be assembled by two methods. By the first assembly method the upper connector 32 is inserted into a joint of two through grooves 26 after a preliminary connection between the crossbeams 2 and the lower connector 31 is completed. Then, the self-tapping screws 331 are vertically inserted into the second socket 3231, the second through hole 222, and the first tube socket 131, so as to further press and fix the crossbeam 2 fixed by the upper connector 32.

[0039] By the second assembly method it is not necessary to install the connecting frame 323 on the upper connector 32. The upper connecting frame 323 is inserted into the socket end 12 and fixed with the self-tapping screws 331, by which it is to be ensured that a distance between the upper connector 32 and the lower connector 31 is greater than a thickness of the transverse reinforcement plate 23. Then, the crossbeam 2 is horizontally inserted into the column 1, by which the lower connector 31 is inserted into the first positioning groove 25 and the upper connector 32 is inserted into the second positioning groove 29.

[0040] Referring to FIG. 7, the crossbeam 2 is further formed with insertion slots 27 on two sides of the through groove 26 that match with the cover plate 5. A bottom surface of the insertion slot 27 is higher than the through groove 26. The cover plate 5 covers the crossbeam 2 hermetically, a length of the cover plate 5 is the same as that of the crossbeam 2, and its two ends are also formed with inclined surfaces with the inclination angle of 45 ° respectively.

[0041] The crossbeam 2 is integrally formed with clamping side strips 271 on two sides of the inner wall of the insertion slot 27 along the horizontal direction. The clamping side strips 271 is located closer to a top opening of the insertion slot 27. A bottom of the cover plate 5 has seal strips 51 on two sides which are configured to be inserted into the insertion slots 27 respectively. The seal strip 51 has a certain elastic deformation performance. When the seal strip 51 is inserted into the insertion slot 27, the clamping side strip 271 will compress and deform a side wall of the seal strip 51 inward, improving a sealing effect between the seal strip 51 and the insertion slot 27. An end of the seal strip 51 is also formed with an inwardly inclined guide part 511.

[0042] Referring to FIG. 8, the screen assembly 4 includes a first screen 41 which is slidably installed on a side wall of the crossbeam 2, and a second screen 42 which is vertically fixed at a bottom of the crossbeam 2. The first screen 41 is generally in a shape of a rectangular frame, and it has three third through holes 411. An inner wall of the third through holes 411 is evenly spaced with screen partitions 412. An inner wall of the crossbeam 2 has a through slot 28 spanning two ends along the horizontal direction, and the first screen 41 slides horizontally to be inserted into the through slot 28.

[0043] The second screens 42 are vertically connected with a bottom wall of the crossbeam 2 and are evenly spaced apart from each other, by which a top and bottom of the second screen 42 are fixed by screws.

[0044] Referring to FIGS. 8 and 9, the base 6 includes a base plate 61 and a vertical rod 62 which is fixedly installed on a top of the base plate 61. The vertical rod 62 includes four L-shaped rods which extend vertically. There are lateral gap 621 between adjacent L-shaped rods. The lateral gaps 621 correspond one-to-one with the first tube sockets 131 of the inner reinforcing frame 11, and a positioning of the base 6 relative to the column 1 can be achieved through the lateral gap 621 and the first tube socket 131. A side wall of the column 1 is provided with a light strip 14.

[0045] The base plate 61 is configured with fourth through holes 611 surrounding the vertical rod 62, which correspond one-to-one with the second tube sockets 132. After completing a preliminary positioning of the base 6 and the column 1, the countersunk screw 332 pass through the fourth through hole 611 and is inserted into the second tube socket 132 to fixedly connect the base 6 and the column 1. A bottom of the base plate 61 is further configured with a clearance slot 612 for accommodating screw heads of countersunk screws 332, so as to prevent interference with the ground-level leveling of the base plate 61.Embodiment 2

[0046] Compared with Embodiment 1, this embodiment has a same structure as Embodiment 1 except for the structure of the cover plate and a presence of a drainage assembly.

[0047] Referring to FIGS. 10, 11 and 12, in order to improve a waterproof effect of a top of the courtyard pergola and minimize the ingress of external rainwater or moisture into the connecting assembly, the present application is further provided with the drainage assembly 7. The drainage assembly 7 includes a storage strip 71, a shim 72, and a guide strip 73.

[0048] The storage strip 71 is an upward-opening U-shaped strip with elastic deformation capability. The storage strip 71 is detachably disposed on an outer side of the cover plate 5, with a length direction that is the same as that of the cover plate 5, and has tearing parts 711 extending to the crossbeam 2 at two ends. The storage strip 71 is installed synchronously with the cover plate 5. After a period of usage, there is water stored in the storage strip 71 that enters a gap between the cover plate 5 and the insertion slot 27. At this moment, the tearing parts 711 may be pulled to remove the entire storage strip 71 from a top of the pergola.

[0049] Two ends of the cover plate 5 have extension parts 52 that extend to the top of the crossbeam 2. The extension parts 52 completely cover the crossbeam 2. The shim 72 is fixed on the inclined surfaces at two ends of the cover plate 5 along the extension direction of the cover plate, and extends to the extension parts 52. The shims 72 on adjacent cover plates 5 abut against each other and press against each other to form a guiding channel with a U-shaped cross-section, a bottom of the guiding channel gradually inclines downward from an outer side to an inner side of the cover plate 5.

[0050] The guide strip 73 is fixedly installed on side walls of adjacent crossbeams 2 on a side away from a center of the pergola. A cross-section of the guide strip 73 is a curved surface that protrudes outward, to minimize the ingress of rainwater into the inner side of the pergola from outside.

[0051] The assembly method of the modular courtyard pergola of the present application is as follows: S1, fixedly connecting the bases and the columns through the self-tapping screws respectively, then placing a plurality of sets of columns and bases at four corners where layout positioning are completed according to design requirements, and fixing the base on the ground using expansion bolts; S2, inserting the lower connector into the socket end at the top of the column, by which there is a clearance between the lower connector and a bottom of the socket end, passing the countersunk screws through the socket end from a side wall of the lower connector to connect the lower connector and the socket end; S3, inserting the respective crossbeams horizontally from two adjacent sides of the socket end respectively, such that bottom surfaces of the respective crossbeams tightly abut against a top surface of the column, inserting the locking element into the strip-shaped through hole, the first through hole, and the first socket in sequence to achieve apreliminary connection between the respective crossbeams and the lower connector; S4, inserting the upper connector vertically into a through groove at the tops of the respective crossbeams, inserting the locking element into the second socket, the second through hole, and the connecting tube in sequence to fix the respective crossbeams, the upper connector, and the socket end; S5, completing the fixation of three sets of crossbeams, where one side of the pergola is open, to slide the first screen horizontally, so that a side wall of the first screen is inserted into the through slot of the crossbeam, and fixing a last set of crossbeams after the first screen is installed on the top of the pergola,; S6, inserting the cover plate into the crossbeam in a sealing manner, fixing the second screen at the bottom of the crossbeam and fixing the light strip on the column as needed.

[0028] The present application is further described in detail below with reference to FIGS. 1-11.

[0029] The present application discloses a modular courtyard pergola and an assembly method.Embodiment 1:

[0030] Referring to FIGS. 1 and 2, a modular courtyard pergola includes a plurality of columns 1 which are vertically erected, a crossbeam 2 which extends horizontally between adjacent columns 1, a connecting assembly configured for connecting the column 1 and the crossbeam 2, a screen assembly 4 on the crossbeam 2, a cover plate 5 for covering the connecting assembly, and a base 6 configured for supporting.

[0031] The column 1 has a full-length rectangular cross-section with open ends. The column 1 is integrally formed with an inner reinforcing frame 11 in its length direction, and the inner reinforcing frame 11 has a #-shaped cross-section. A top of the column 1 is milled to form a socket end 12. The socket end 12 is a # - shaped inner hole of the inner reinforcing frame 11, which means that the cross-section of the socket end 12 is rectangular. In order to facilitate connection between the column 1 and the base 6 with the connecting assembly, the inner reinforcing frame 11 is integrally formed with a tube socket 13. The tube socket 13 includes a first tube socket 131 in the # - shaped inner hole and a second tube socket 132 at four corners of #- shaped inner hole. The first tube socket 131 and the second tube socket 132 are both arc-shaped tubes with one open end.

[0032] The crossbeam 2 is a rectangular pipe, two ends thereof are both formed with inclined sockets 21 which can be horizontally inserted into the socket ends 12 respectively. An inclination angle of the inclined socket 21 is 45° . The crossbeam 2 is provided with a top plate 22, a transverse reinforcement plate 23, and a bottom plate 24 spaced from top to bottom along a height direction. Both ends of the bottom plate 24 and ends of the top plate 22 are flush with the inclined sockets 21 respectively, and a length of the transverse reinforcement plate 23 is smaller than that of the bottom plate 24. A first positioning groove 25 is formed between the transverse reinforcement plate 23 and the bottom plate 24. A second positioning groove 29 is formed between the transverse reinforcement plate 23 and the top plate 22.

[0033] Referring to FIGS. 2 and 3, the connecting assembly includes a lower connector 31, an upper connector 32, and locking elements 33. In this embodiment, the locking elements 33 are self-tapping screws 331 and countersunk screws 332. The lower connector 31 is sleeved on the socket end 12, which includes a sleeve part 311 and first extension parts 312 which are provided on adjacent sides of the sleeve part 311. The sleeve part 311 has a rectangular inner hole that is adapted to the socket end 12. The lower connector 31 and the socket end 12 are fixedly connected by the countersunk screws 332, the countersunk screws 332 pass through the sleeve part 311 and the socket end 12 along a horizontal direction. There is a seal gap 34 between a bottom wall of the lower connector 31 and the column 1.

[0034] Extension directions of the two first extension parts 312 are perpendicular to each other. Each first extension 312 is integrally formed with first sockets 313 on opposite inner side walls. A cross-section of the first socket 313 is an arc-shaped ring, a curvature of the arc-shaped ring is greater than 180° . An inner wall of the first socket 313 is vertically provided with convex parts 3131 along a circumferential direction.

[0035] After fixing the lower connector 31 with the socket end 12, the crossbeam 2 is installed. When horizontally inserting the crossbeam, the bottom plate 24 is inserted into the seal gap 34, and the two first extension parts 312 are respectively inserted into the first positioning grooves 25 between the transverse reinforcement plates 23 and the bottom plates 24. The transverse reinforcement plate 23 has a first through hole 231 corresponding to the first socket 313, and the top plate 22 has a strip-shaped through hole 221 corresponding to the first through hole. The first through hole 231 is adapted to the locking element 33, and a size of the strip-shaped through hole 221 is larger than that of the first through hole 231.

[0036] Referring to FIGS. 4, 5 and 6, the upper connector 32 is configured to insert into a joint of adjacent crossbeams 2, and it includes a positioning part 321 and second extension parts 322 on two adjacent side walls of the positioning part 321. A size of the upper connector 32 is the same as that of the lower connector 31, and a difference between the upper connector 32 and the lower connector 31 is that the upper connector is provided with a rectangular connecting frame 323 inside the positioning part 321. The connecting frame 323 is integrally formed or detachably connected with the upper connector 32. In this embodiment, the connecting frame 323 and the upper connector 32 are fixedly connected by the countersunk screws 332.

[0037] Inner walls of the connecting frame 323 are all provided with second sockets 3231 that are structurally consistent with the first tube socket 131.

[0038] The upper connector 32 can be assembled by two methods. By the first assembly method the upper connector 32 is inserted into a joint of two through grooves 26 after a preliminary connection between the crossbeams 2 and the lower connector 31 is completed. Then, the self-tapping screws 331 are vertically inserted into the second socket 3231, the second through hole 222, and the first tube socket 131, so as to further press and fix the crossbeam 2 fixed by the upper connector 32.

[0039] By the second assembly method it is not necessary to install the connecting frame 323 on the upper connector 32. The upper connecting frame 323 is inserted into the socket end 12 and fixed with the self-tapping screws 331, by which it is to be ensured that a distance between the upper connector 32 and the lower connector 31 is greater than a thickness of the transverse reinforcement plate 23. Then, the crossbeam 2 is horizontally inserted into the column 1, by which the lower connector 31 is inserted into the first positioning groove 25 and the upper connector 32 is inserted into the second positioning groove 29.

[0040] Referring to FIG. 7, the crossbeam 2 is further formed with insertion slots 27 on two sides of the through groove 26 that match with the cover plate 5. A bottom surface of the insertion slot 27 is higher than the through groove 26. The cover plate 5 covers the crossbeam 2 hermetically, a length of the cover plate 5 is the same as that of the crossbeam 2, and its two ends are also formed with inclined surfaces with the inclination angle of 45 ° respectively.

[0041] The crossbeam 2 is integrally formed with clamping side strips 271 on two sides of the inner wall of the insertion slot 27 along the horizontal direction. The clamping side strips 271 is located closer to a top opening of the insertion slot 27. A bottom of the cover plate 5 has seal strips 51 on two sides which are configured to be inserted into the insertion slots 27 respectively. The seal strip 51 has a certain elastic deformation performance. When the seal strip 51 is inserted into the insertion slot 27, the clamping side strip 271 will compress and deform a side wall of the seal strip 51 inward, improving a sealing effect between the seal strip 51 and the insertion slot 27. An end of the seal strip 51 is also formed with an inwardly inclined guide part 511.

[0042] Referring to FIG. 8, the screen assembly 4 includes a first screen 41 which is slidably installed on a side wall of the crossbeam 2, and a second screen 42 which is vertically fixed at a bottom of the crossbeam 2. The first screen 41 is generally in a shape of a rectangular frame, and it has three third through holes 411. An inner wall of the third through holes 411 is evenly spaced with screen partitions 412. An inner wall of the crossbeam 2 has a through slot 28 spanning two ends along the horizontal direction, and the first screen 41 slides horizontally to be inserted into the through slot 28.

[0043] The second screens 42 are vertically connected with a bottom wall of the crossbeam 2 and are evenly spaced apart from each other, by which a top and bottom of the second screen 42 are fixed by screws.

[0044] Referring to FIGS. 8 and 9, the base 6 includes a base plate 61 and a vertical rod 62 which is fixedly installed on a top of the base plate 61. The vertical rod 62 includes four L-shaped rods which extend vertically. There are lateral gap 621 between adjacent L-shaped rods. The lateral gaps 621 correspond one-to-one with the first tube sockets 131 of the inner reinforcing frame 11, and a positioning of the base 6 relative to the column 1 can be achieved through the lateral gap 621 and the first tube socket 131. A side wall of the column 1 is provided with a light strip 14.

[0045] The base plate 61 is configured with fourth through holes 611 surrounding the vertical rod 62, which correspond one-to-one with the second tube sockets 132. After completing a preliminary positioning of the base 6 and the column 1, the countersunk screw 332 pass through the fourth through hole 611 and is inserted into the second tube socket 132 to fixedly connect the base 6 and the column 1. A bottom of the base plate 61 is further configured with a clearance slot 612 for accommodating screw heads of countersunk screws 332, so as to prevent interference with the ground-level leveling of the base plate 61.Embodiment 2
