Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and in particular to a node assembly, a lattice shell structure and a glass connection system. Background Art

[0002] Since the single-layer grid shell structure and its glass connection system have the advantages of being light, thin and transparent, the single-layer grid shell structure is adopted by more and more buildings for special-shaped curtain walls, canopies and awnings. The nodes of the single-layer grid shell structure are the key components of the entire structure. The nodes determine the connection position and connection method of the rods in the single-layer grid shell structure. The current single-layer grid shell structure usually needs to be constructed by on-site splicing and welding. However, the current single-layer grid shell structure has low splicing efficiency and accuracy of the nodes, which affects the construction efficiency and quality, resulting in a high proportion of labor costs in the project budget, which is not conducive to saving construction costs.

[0011] The first positioning surface abuts against the positioning block in the positioning opening, and the second positioning surface abuts against the plug board in the slot, or the first positioning surface and the second positioning surface abut against the main bodies of two adjacent tubes respectively.

[0012] In one embodiment, the slot and the positioning opening correspond to the midpoint of the edge of the body respectively; and / or,

[0013] The slot penetrates the plug board along the axial direction of the body, and the positioning opening penetrates the positioning block along the axial direction of the body.

[0014] In one of the embodiments, two node plates are further included, and the two node plates are respectively arranged on two opposite sides of the splicing plate.

[0034] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the lattice shell structure 10 in some embodiments, Figure 2Schematic diagram of the structure of the node assembly 110 in some embodiments. In some embodiments, the lattice shell structure 10 can be a single-layer lattice shell structure 10, which includes a plurality of node assemblies 110 and a plurality of rods 120, and the node assembly 110 includes a plurality of tubes 1120 arranged along the circumferential direction, and the two ends of each rod 120 are respectively connected to the tubes 1120 of two of the node assemblies 110. Of course, Figure 1 The schematic diagram of only part of the structure of the grid shell structure 10 in some embodiments may be illustrated. In fact, according to different building requirements, the grid shell structure 10 may also include a larger number of node components 110 and rods 120. The grid shell structure 10 can be used in structures such as special-shaped curtain walls, canopies or awnings of buildings.

[0035] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, Figure 3 is a schematic diagram of a partial structure of the node component 110 in some embodiments, Figure 4 is a schematic diagram of a splicing plate 1110 in some embodiments, Figure 5 is a schematic diagram of the structure of the tube body 1120 in some embodiments, Figure 6 Schematic diagram of the structure of the tube body 1120 and the splicing plate 1110 in some embodiments. In some embodiments, the node assembly 110 includes a splicing plate 1110 and at least two tube bodies 1120, and the at least two tube bodies 1120 are arranged along the circumference of the splicing plate 1110 and are respectively spliced ​​with the splicing plate 1110. Specifically, the splicing plate 1110 includes a main body 1111 and at least two splicing blocks 1115 arranged at intervals along the circumference of the main body 1111, and the splicing blocks 1115 are adapted to the tube body 1120. The tube body 1120 corresponds to the splicing blocks 1115 one by one, and the tube body 1120 includes a main body 1121, a plug-in plate 1122, and a positioning block 1124. The plug-in board 1122 and the positioning block 1124 are respectively arranged at two opposite edges of the end of the body 1121. For example, the plug-in board 1122 and the positioning block 1124 are formed by extending from two opposite edges of the end of the body 1121 toward the splicing board 1110. The size of the positioning block 1124 in the axial direction of the body 1121 is smaller than that of the plug-in board 1122. The plug-in board 1122 is provided with a slot 1123 adapted to the body 1111, and the positioning block 1124 is provided with a positioning opening 1125 adapted to the body 1111. When the splicing board 1110 is spliced ​​with the tube body 1120, the splicing block 1115 is embedded in the body 1121 of the corresponding tube body 1120, and the parts of the body 1111 located on both sides of the splicing block 1115 are respectively inserted into the slot 1123 and the positioning opening 1125 of the tube body 1120 corresponding to the splicing block 1115.

[0036] It should be noted that in the present application, the description of the splicing block 1115 being adapted to the tube body 1120 can be understood as the splicing block 1115 being able to be embedded in the body 1121, and when the splicing block 1115 is embedded in the body 1121, the two sides of the splicing block 1115 respectively abut against the two opposite inner walls of the body 1121. For example, in some embodiments, the body 1121 is a rectangular pipe structure with openings at both ends, and the width of the splicing block 1115 is adapted to the width of the body 1121. In this embodiment, when the body 1121 is a rectangular pipe structure with openings at both ends, the axial direction of the body 1121 is parallel to the length direction of the body 1121. The description that the slot 1123 and the positioning hole 1125 are both adapted to the main body 1111 can be understood as the thickness of the main body 1111 being adapted to the size of the slot 1123 and the positioning hole 1125. In other words, when the main body 1111 is inserted into the slot 1123 and the positioning hole 1125, the two opposite surfaces of the main body 1111 respectively abut against the plug-in board 1122 and the positioning block 1124, thereby being able to fix the relative positions of the main body 1111 and the tube body 1120 in a direction perpendicular to the main body 1111.

[0037] The description that the tubes 1120 correspond to the splicing blocks 1115 one to one only means that the tubes 1120 correspond to the splicing blocks 1115 in quantity, not in shape. Figure 2 and Figure 3 In the illustrated embodiment, the splicing plate 1110 is provided with six splicing blocks 1115, and six tube bodies 1120 are provided accordingly, and each tube body 1120 is spliced ​​with one splicing block 1115. The tube body 1120 may correspond to the splicing block 1115 in shape, in other words, each tube body 1120 is only spliced ​​with a specific splicing block 1115. The shapes of the tube body 1120 and the splicing block 1115 may not correspond, for example, the shapes of the multiple tube bodies 1120 are the same, and the tube bodies 1120 correspond to the splicing blocks 1115 in number, but each tube body 1120 may be spliced ​​with any splicing block 1115.

[0038] In the above-mentioned node assembly 110, during the assembly process, the splicing block 1115 is embedded in the main body 1121, and the parts of the main body 1111 located on both sides of the splicing block 1115 are respectively inserted into the slot 1123 and the positioning port 1125, which can make the splicing of the pipe body 1120 and the splicing plate 1110 quick and accurate, and improve the splicing efficiency and accuracy. At the same time, the axial size of the positioning block 1124 in the main body 1121 is smaller than the plug-in board 1122, which can prevent the splicing of the positioning blocks 1124 and the plug-in board 1122 of two adjacent pipe bodies 1120 from interfering with each other, making the splicing of the node assembly 110 smoother. The splicing block 1115 is adapted to the pipe body 1120, and the design that the main body 1111 is adapted to the slot 1123 and the positioning port 1125 can also make the splicing of the pipe body 1120 and the splicing plate 1110 more reliable, improve the splicing quality, and prevent the deformation of the node assembly 110 during the welding process.

[0039] It is understandable that the number of the splicing blocks 1115 on the splicing plate 1110 determines the number of the tubes 1120 that can be spliced ​​with the splicing plate 1110, which in turn affects the number of rods 120 in the lattice shell structure 10 and the angles between adjacent rods 120. Figure 1 and Figure 3 In the embodiment shown, six tubes 1120 are evenly distributed along the circumference of the splicing plate 1110, and the axis of the rod 120 connecting two adjacent tubes 1120 forms an angle of 60°. Of course, according to actual building requirements, the number of splicing blocks 1115 on the splicing plate 1110 can also be set in other ways, such as three, four, five or more.

[0040] For reference Figure 1 and Figure 7 As shown, Figure 7 Schematic diagram of the alternation of the plug-in board 1122 and the positioning block 1124 in some embodiments. In some embodiments, a plurality of tubes 1120 are arranged in sequence along the circumference of the splicing plate 1110, and in the circumference of the main body 1111, the plug-in board 1122 and the positioning block 1124 are arranged alternately in sequence. In other words, any plug-in board 1122 is adjacent to the positioning block 1124 of another tube 1120, and any positioning block 1124 is adjacent to the plug-in board 1122 of another tube 1120. In this way, the design that the size of the positioning block 1124 in the axial direction of the main body 1121 is smaller than the plug-in board 1122 can reasonably configure the structural layout of the node assembly 110, so that the splicing of two adjacent tubes 1120 and the splicing plate 1110 will not interfere with each other, and at the same time make the structure of the node assembly 110 more compact and improve the space utilization. It can be understood that in this embodiment, the plug-in boards 1122 of any two adjacent tubes 1120 are inclined to each other.

[0041] Furthermore, combined with Figure 7 and Figure 8 As shown, Figure 8 for Figure 7 A partial enlarged view of the A area shown. In some embodiments, the positioning block 1124 is formed with an inclined surface 1126 inclined to the axial direction of the body 1121, and the inclined surface 1126 of any tube body 1120 abuts against the side wall of the plug-in board 1122 of the adjacent tube body 1120. In other words, a plurality of tube bodies 1120 are sequentially arranged and closely abutted along the circumference of the splicing plate 1110, and the side wall of the plug-in board 1122 of each tube body 1120 abuts against the inclined surface 1126 of the adjacent tube body 1120, and at least partially corresponds to the space in the body 1121. Such a configuration can further improve the compactness of the node assembly 110 structure, thereby improving the space utilization rate, and the design of the abutment between the inclined surface 1126 and the plug-in board 1122 can also improve the accuracy of the splicing of the tube body 1120 and the splicing plate 1110.

[0042] Please see again Figure 3 and Figure 4 In some embodiments, the main body 1111 is provided with a protrusion 1112 located between two adjacent splicing blocks 1115, and a protrusion 1112 is provided between any two adjacent splicing blocks 1115. In other words, the number of protrusions 1112 corresponds to the number of splicing blocks 1115. The protrusion 1112 includes a first positioning surface 1113 and a second positioning surface 1114 that are connected to each other and set at an angle, and the first positioning surface 1113 and the second positioning surface 1114 are respectively connected to adjacent splicing blocks 1115. When the splicing plate 1110 is spliced ​​with the tube body 1120, part of the protrusion 1112 is inserted into the slot 1123 of one of the tube bodies 1120, and the other part is inserted into the positioning port 1125 of another tube body 1120 adjacent to the tube body 1120. Furthermore, the first positioning surface 1113 abuts against the positioning block 1124 in the positioning opening 1125 of one of the tube bodies 1120, and the second positioning surface 1114 abuts against the plug board 1122 in the slot 1123 of the other tube body 1120, or the first positioning surface 1113 and the second positioning surface 1114 respectively abut against the main bodies 1121 of the two adjacent tube bodies 1120.

[0043] Specifically, refer to Figure 3 and Figure 5As shown, in some embodiments, the slot 1123 penetrates the plug board 1122 along the axial direction of the body 1121, and the positioning opening 1125 penetrates the positioning block 1124 along the axial direction of the body 1121. In other words, the slot 1123 divides the plug board 1122 into two parts that are not connected to each other, and the positioning opening 1125 divides the positioning block 1124 into two parts that are not connected to each other. Therefore, in this embodiment, when the parts of the main body 1111 located on both sides of the splicing block 1115 are inserted into the slot 1123 and the positioning opening 1125, the protrusion passes through the positioning opening 1125 and the first positioning surface 1113 abuts the body 1121, the body 1121 and the positioning block 1124 limit the protrusion from three directions, the protrusion passes through the slot 1123 and the second positioning surface 1114 abuts the body 1121, and the body 1121 and the plug board 1122 limit the protrusion from three directions. In other embodiments, the slot 1123 does not penetrate the plug board 1122, and the positioning opening 1125 does not penetrate the positioning block 1124. When the main body 1111 is inserted into the slot 1123 and the positioning opening 1125, the raised first positioning surface 1113 and the second positioning surface 1114 respectively abut the bottom surfaces of the slot 1123 and the positioning opening 1125.

[0044] In some embodiments, the slot 1123 and the positioning opening 1125 correspond to the midpoint of the edge of the body 1121, for example, the lengths of the plug board 1122 and the positioning block 1124 on the edge of the body 1121 are equal and the positions correspond, the slot 1123 is set at the position of the plug board 1122 corresponding to the midpoint of the edge of the body 1121, and the positioning opening 1125 is set at the position of the positioning block 1124 corresponding to the midpoint of the edge of the body 1121, then the slot 1123 and the positioning opening 1125 on the edge of the body 1121 correspond. In this way, the rationality of the structural layout of the tube body 1120 and the splicing plate 1110 can be improved.

[0045] refer to Figure 3 As shown, in some embodiments, the node assembly 110 further includes two node plates 1130, and the two node plates 1130 are respectively located on opposite sides of the splicing plate 1110. The node plate 1130 includes at least two connection surfaces 1131 along the circumferential side, and the connection surfaces 1131 correspond to the tube bodies 1120 one by one, and each connection surface 1131 is connected to the end surface of a corresponding body 1121. For example, in Figure 2 and Figure 3 In the illustrated embodiment, the node plate 1130 includes six interconnected connection surfaces 1131 along the circumferential side, each connection surface 1131 is connected to the end face of a corresponding body 1121, and the two node plates 1130 block the space on both sides of the splicing plate 1110 and can improve the connection effect between the tube bodies 1120.

[0046] Furthermore, in some embodiments, the surface of the node plate 1130 facing away from the splicing plate 1110 is flush with or higher than the surface of the body 1121. In other words, in a direction perpendicular to the splicing plate 1110, the body 1121 does not exceed the surface of the node plate 1130 facing away from the splicing plate 1110. The node plate 1130 and the tube body 1120 can be fixedly connected by welding or the like, and the provision of the node plate 1130 can improve the structural strength of the node assembly 110.

[0047] Please see again Figure 3 and Figure 6 As described above, in some embodiments, the two end surfaces of the plug-in board 1122 respectively abut against the side of the two node plates 1130 facing the splicing plate 1110, and the two end surfaces of the positioning block 1124 respectively abut against the side of the two node plates 1130 facing the splicing plate 1110. It can be understood that the end surface of the body 1121 has four edges, of which the plug-in board 1122 and the positioning block 1124 are respectively provided at two opposite edges, and both ends of the plug-in board 1122 and the positioning block 1124 do not completely cover the edge of the body 1121. In other words, the two ends of the two edges of the end surface of the body 1121 provided with the plug-in board 1122 and the positioning block 1124 are reserved for abutting against the node plate 1130, for example, the two end surfaces of the plug-in board 1122 and the positioning block 1124 form steps with the end surface of the body 1121. The node plate 1130 is located in the step formed by the plug-in plate 1122, the positioning block 1124 and the body 1121. The side surface of the node plate 1130 abuts against the end surface of the body 1121, and the surface of the node plate 1130 facing the splicing plate 1110 abuts against the end surfaces of the plug-in plate 1122 and the positioning block 1124. In this way, the tube body 1120 and the node plate 1130 can also limit each other, so that the splicing of the node assembly 110 is more accurate, and the structural strength of the splicing of the node assembly 110 is improved. In addition, the two node plates 1130 can also cover the plug-in plate 1122, the splicing plate 1110 and the positioning block 1124 and other structures between the two node plates 1130, so that the node assembly 110 is more beautiful.

[0048] At the same time, due to the mutual limitation of the splicing block 1115, the slot 1123, the positioning port 1125 and the node plate 1130, the node assembly 110 is firmly spliced, and the various structures of the node assembly 110 are not easily deformed during welding, which is conducive to improving the assembly quality and assembly efficiency. In some embodiments, the tube body 1120 and the rod 120 are both formed by laser cutting of high-precision cold-rolled steel pipes, and welding is no longer required to form the tube body 1120 and the rod 120 during assembly, and deformation of the tube body 1120 and the rod 120 after welding can also be avoided.

[0049] refer to Figure 2 and Figure 3As shown, in some embodiments, the tube body 1120 further includes an end plate 1127, which is disposed at one end of the body 1121 away from the splicing plate 1110 and blocks the end of the body 1121, and the end plate 1127 is provided with spaced threaded holes 1128 and cable holes 1129. The rod 120 is also a hollow rectangular pipe structure with two ends open, and the two ends of the rod 120 are also provided with end plates 1127 blocking the two ends of the rod 120. When the rod 120 is connected to the tube body 1120, the threaded hole 1128 of the end plate 1127 of the rod 120 is opposite to the threaded hole 1128 of the end plate 1127 of the tube body 1120, and the end plate 1127 of the rod 120 is connected to the end plate 1127 of the tube body 1120 by threads. The cable hole 1129 of the end plate 1127 of the rod 120 is opposite to the cable hole 1129 of the end plate 1127 of the tube body 1120. The cable can extend through the cable hole 1129 in the space inside the rod 120 and the tube body 1120 and the space between the node plate 1130 and the splicing plate 1110, which is beneficial to improving the space utilization rate of the lattice shell structure 10 and making the lattice shell structure 10 more beautiful.

[0050] In addition, Figure 2 and Figure 3 In the illustrated embodiment, the surface of the node plate 1130 facing away from the splicing plate 1110 is a plane. In other embodiments, the surface of the node plate 1130 facing away from the splicing plate 1110 can also be set as a curved surface, for example, a curved surface with a high middle and a low periphery. In this way, the node plate 1130 smoothly transitions to the tube body 1120, and the curve of the node plate 1130 is smoother, and it is not easy to have unevenness or wrinkles, which is conducive to making the node assembly 110 more beautiful.

[0051] In some embodiments, before the splicing of the lattice shell structure 10, the surface of each component of the lattice shell structure 10 can be sprayed. Compared with spraying at the construction site, the components of the lattice shell structure 10 can be made more beautiful, avoid rust, and help improve the efficiency of on-site construction. Of course, since the node assembly 110 has a high space utilization rate and occupies a small space, the node assembly 110 can also be spliced ​​and welded before the on-site construction, so that the construction site does not need to splice and weld the node assembly 110, which is conducive to improving construction efficiency. In addition, the manufacture of each component of the node assembly 110 and the splicing and welding of the node assembly 110 can be achieved through automated production. For example, by parameterizing the design of the node assembly 110 and extracting data packets using a program, laser numerical control precision cutting can be achieved to form each component of the node assembly 110, and then automatically splicing by a manipulator, and automatically welding and laser scanning measurement are performed by a welding robot to ensure the splicing quality. Due to the design of the splicing block 1115, the slot 1123, the positioning port 1125, the connecting surface 1131, etc., the components of the node assembly 110 are mutually limited, which can greatly simplify the splicing process of the node assembly 110, improve the splicing efficiency and splicing quality, and also avoid deformation of the node assembly 110 during welding.

[0052] The present application also provides a glass connection system (not shown), comprising glass and a lattice shell structure 10 as described in any of the above embodiments. The glass is fixed to the lattice shell structure 10, for example, fixed to the rod 120 of the lattice shell structure 10.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
