It should be noted that the building includes multiple connectors of one or more types mentioned above, and also has a square tube 200 with a second opening 201, and a quadrilateral folded panel 300 adapted to the second opening 201; the square tube 200 is provided with a fixing through hole 202 adapted to the support portion through hole 211 of each support portion 21, the outer wall of the square tube 200 is adapted to the inner wall of the support portion 21, and the second opening 201 is located in the middle of one side of the square tube 200; the folded panel 300 has a fixing through hole 202 at each of its four edges. The insertion surface 301, adapted to the second opening 201, has a thickness not exceeding half the width of the second opening 201. The insertion surface 301 has an insertion surface through hole 301a adapted to the support through hole 211 of each support part 21. During assembly, the support through hole 211 and the insertion surface 301 can be bolted to the same fixing through hole 202 on the square tube 200; that is, the support through hole 211, the fixing through hole 202, and the insertion surface through hole 301a are fixed by bolts. Alternatively, the support through hole 211 and the insertion surface 301 can also be bolted to fixing through holes 202 located at different positions on the square tube 200. The fixing through hole 202 can be set according to actual needs and is not specifically limited here. Similarly, the length of the insertion surface 301 can be the same as the length of the corresponding side of the folded panel. As an optional case, the length of the insertion surface 301 can also be less than the length of the corresponding side of the folded panel 300. For example, the support 21 and the insertion surface 301 are fixedly connected by bolts through different fixing through holes 202 on the square tube 200, which will not be described in detail here.

[0080] As an optional implementation, the square tube 200 described above may include, for example, Figures 23 to 26 The square tube structure type. For example... Figure 23 As shown, a second opening 201 is provided at the middle position of one side of the square tube 200 along the axial direction. Four pairs of fixing through holes 202 are sequentially provided along the axial direction on opposite sides of the second opening 201. The fixing through holes 202 at both ends are respectively used to mate with the through holes in the connector and the through holes 301a in the insertion surface, and the three parts are fixedly connected by bolts. The fixing through holes 202 in the middle are respectively used to connect and fix with one or more of the aforementioned combined connectors by bolts. The second opening 201 is used for the insertion of the insertion surface 301 and can be adapted to the thickness of the insertion surface 301; further details are omitted here.

[0081] like Figure 24As shown, a square tube 200 has a fixing through hole 202 adapted to the through hole 211 of the support portion at the location of the second opening 201 at one end, and a fixing through hole 202 adapted to the through hole 211 of the support portion is provided on the side surface adjacent to the second opening 201 at the other end. By providing fixing through holes 202 at appropriate positions on different sides, the square tube 200 can be used to fasten multiple adjacent and different connecting surfaces of the connector and the insertion surface 301 together by bolts.

[0082] like Figure 23 The square tube 200 shown is extended in the extension direction according to a corresponding preset dimension to obtain the following: Figure 25 and Figure 26 The square tube 200 shown above can improve the efficiency of loading and unloading, and enhance the stability of the connection. In particular, during subsequent maintenance, the extended square tube 200 can be used to replace the corresponding damaged connectors, square tube 200 and folded panel 300, and further enhance its stability after maintenance.

[0083] It should be noted that the length, inner diameter, outer diameter and second opening 201 of the above-mentioned different types of square tubes 200 are not fixed and can be of various compatible sizes, as long as the above-mentioned structural dimensions of the square tubes 200 are compatible with the structural dimensions of the connectors and the folded panel 300, which will not be elaborated here.

[0084] As an optional implementation, the folding panel 300 described above may include, for example, Figures 27 to 30 Folded panel structure type. For example... Figure 27 As shown, the side length of the square folded panel 300 is the same as the tube length of the square tube 200. The insertion surface 301 is basically perpendicular to the square folded panel 300. The insertion surface through hole 301a, the fixing through hole 202 of the square tube 200, the support through hole 211 of the connecting part on the connector, and the bolt are compatible, and can play a role in positioning, support, and fixing in application. No specific limitation is made on the length or width of the insertion surface 301. Similarly, as... Figure 28 As shown, at the specially reinforced combined connector, when the folded panel 300 is connected to the square tube 200 and the support portion 21 of the connector, there is partial obstruction between the folded panel 300 and the support portion 21. A chamfer 302 (including a first chamfer 302a, a second chamfer 302b, and a third chamfer 302c) is provided at the location where the folded panel 300 partially obstructs the connection. Corresponding chamfers 302 are provided at corresponding positions on the folded panel 300, such as... Figures 28 to 30As shown below, details will not be repeated here. Additionally, when one or more of the aforementioned first chamfer 302a, second chamfer 302b, and third chamfer 302c are combined, a symmetrical structure can be created at the four corners of the square folded panel 300 (not shown in the figure), depending on the actual situation. Further details will not be provided here. It should also be noted that when the folded panel 300 can be used as a top cover, the insertion surface through hole 301a may not be provided on the insertion surface 301. Simply inserting the insertion surface 301 into the corresponding second opening 201 can also achieve the function of covering and connecting (not shown in the attached figure). This is for illustrative purposes only and will not be elaborated upon here.

Two or five connectors of the same structure can be selected at intervals between the connectors at the four corners of the bottom surface, except that the opening direction of the ninth branch 21i is arranged facing the inside of the pointed hexahedron. The connectors on the bottom and vertical sides of the pointed hexahedron, except at the edges, all adopt the following... Figure 3 The connecting piece shows a cross-shaped structure. At the top of the vertical side of the pointed hexahedron (i.e., the shoulder of the pointed hexahedron), along... Figure 31 The shoulders of the mesohexahedron along its length are symmetrically distributed on both sides as follows: Figure 8 The connectors shown are arranged opposite each other, and the opening directions of their seventh branch 21g at the four corners of the shoulder structure are also opposite. A similar connector is also used between the bottom corner and the shoulder corner.

The remaining supporting portions 21 of the other two T-shaped structures are symmetrically arranged downwards on both sides of the middle T-shaped connector, with their downward-facing supporting portions 21 opening inwards.

Within the closed frame of the square structure formed by the support portions 21 and the square tube 200, the aforementioned folded panel 300 can be used for sealing. The sloping surfaces on both sides of the top of the pointed hexahedron can be sealed with rectangular cover plates similar in structure to the folded panel 300 and their fixing through holes 202 in the square tube 200 above the slope using bolts. Optionally, in the vertically triangular areas on both sides of the slope, a triangular cover plate can be selected and its fixing through hole 202 in the adjacent square tube 200 can be sealed with bolts. The structure of the square tube 200 and the cover plate, as well as the specific details of the sealing, will not be elaborated here.

The connectors on the bottom and vertical sides of the hexahedron, except for those at the edges, all adopt the same structure.) Figure 3 The cross-shaped connector shown can be used at the edges on the vertical sides of the hexahedron or at the four corners at the top. Figure 4 The connectors in the middle, other parts can use such as Figure 3 The connector shown uses the following method: Figure 3 When using the connector shown, the opening faces inwards from the hexahedron. Figure 32 The connectors at the edges of the top surface of the hexahedron shown all adopt the following... Figure 20 The connector shown has an eleventh branch 21k (not shown in the figure) facing downwards and inserted into the branch 21 of its lower connector. All connectors on the top surface of the hexahedron, except those at the edges, can be connectors with a cross-shaped structure, such as... Figure 3 , Figure 12 , Figure 13 , Figure 20 , Figure 21 Any type of connector. Similarly, the connecting portions 21 of the connectors arranged in the hexahedron above are fitted with suitable square tubes 200, and the positions of the second opening 201 and the fixing through hole 202 in the square tube 200 are aligned with the connectors arranged above (including each connecting portion 21 and the connecting portion through hole 211). Within the closed frame of the square structure formed by the connecting portions 21 and the square tube 200, the folded panel 300 can be used for sealing. The structure of the square tube 200 and the cover plate, as well as the specific details of the sealing, are described above and in the accompanying drawings, and will not be repeated here.

[0088] As an optional implementation, such as Figures 33 to 35 As shown, when the building assembled with the above-mentioned connectors is a double-beam flat-top hexahedron, the four corners of the bottom surface can be constructed using the following method: Figure 21 One of the connectors has a twelfth branch, 21m in length, and its side is designed as follows: Figure 2 The T-shaped connector 21t shown has a central section using... Figure 6 The connectors shown are assembled as follows Figure 33 The first assembly connector 21z1 shown. It can be used between the bottom corners and on the edges formed by the four vertical faces of the hexahedron. Figure 21 One of the connectors has a twelfth branch, 21m in length, and its side is designed as follows: Figure 3 The cross-shaped connector 21s shown is assembled as follows: Figure 34 The second assembly connector 21z2 is shown.

The structure of the square tube 200 and the cover plate, as well as the specific details of the sealing, are described above and in the accompanying drawings, and will not be repeated here.

[0089] In embodiments of this utility model, such as Figures 1 to 30 When assembling a building, the connectors, square tubes 200, and folded panels 300 can be omitted based on the excess design or structural dimensions of the extra support parts 21 that extend from the corners of the building that do not participate in the connection, or the second opening 201 or the fixed through hole 202, or the structure of the plug-in surface 301. This can save materials for making connectors and reduce the material cost of assembling the building.

[0090] In embodiments of this utility model, such as Figures 31 to 35 As shown, a building is assembled using connectors, which are not limited to the following: Figure 33 and Figure 34 The structural combination, combined with square tubes 200 and folded panels 300, allows for the assembly of buildings of different forms and stable structures. Because the aforementioned connectors have a cubic intersection 1 and a connecting part 2 consisting of a U-shaped or square cross-section support 21, the assembly of these buildings is more convenient, faster, more efficient, and more stable, while also saving on the cost of widespread application. Buildings assembled using the aforementioned connectors are not limited to those disclosed in this specification; other similar buildings assembled through simple replacement and combination are also within the scope of protection of this application.
