Welding connection requires a large amount of on - site welding, consumes a lot of man - hours, cannot be disassembled without damage, and is not convenient for reuse. When bolt connection is used for large - span structures, a large number of bolts are required, connection plates need to be set, which increases the steel consumption, and has high processing precision requirements, increasing the project cost. After disassembly, the bolts are scrapped, and if reused, it will increase the project cost.

[0003] In the prior art, there is a bow - type support structure and its installation method, which includes cross - insertion joints, T - shaped insertion joints and right - angle insertion joints, avoiding on - site welding and bolt connection of large - span structures, and being easy to disassemble, facilitating repeated installation and use. However, the cross - insertion joints, T - shaped insertion joints and right - angle insertion joints proposed in the above patent are all inserted through square tubes, with high installation precision requirements and inconvenient installation.

[0004] Defects of the prior art:

[0005] Welding connection of large - span structures has the disadvantages of a large amount of on - site welding, high man - hour consumption, inability to be disassembled without damage, and inconvenience for reuse. Bolt connection of large - span structures has the disadvantages of high steel consumption, many bolt requirements, high processing precision requirements, high project cost, and bolt scrapping after disassembly. If reused, it will increase the project cost. Cross - insertion joints, T - shaped insertion joints and right - angle insertion joints are easy to disassemble, but have the disadvantages of high installation precision requirements and inconvenient installation.

[0063] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0064] Example 1:

[0065] In the first aspect of this example, a spindle mortise and tenon connection node for assembly connection is provided, especially applied to an arch support, such as Figure 1 shown, the spindle mortise and tenon connection node includes a connecting piece, and components connected by the connecting piece;

[0066] such as Figure 2 shown, the components include: a first component 100 and a second component 200;

[0067] such as Figure 3 and Figure 4 shown, the connecting piece 300 includes: a first connecting piece 310, a second connecting piece 320 and a node area component 330; the first connecting piece 310 includes: a first left tapered sleeve 311, a first right tapered sleeve 312 and a first spindle connecting piece 313; the second connecting piece 320 includes: a second left tapered sleeve 321, a second right tapered sleeve 322 and a second spindle connecting piece 323; the connecting piece 300 is arranged between the first component 100 and the second component 200 for connecting and fixing the first component 100 and the second component 200; the first left tapered sleeve 311 is arranged inside one end of the first component 100, and the first left tapered sleeve 311 and the first component 100 are integrally connected by welding; the first right tapered sleeve 312 is arranged inside one end of the node area component 330, and the first right tapered sleeve 312 and the node area component 330 are integrally connected by welding; the end face of the first left tapered sleeve 311 is attached to the end face of the first right tapered sleeve 312; the second left tapered sleeve 321 is arranged inside the other end of the node area component 330, and the second left tapered sleeve 321 and the node area component 330 are integrally connected by welding; the second right tapered sleeve 322 is arranged inside one end of the second component 200, and the second right tapered sleeve 322 and the second component 200 are integrally connected by welding; the end face of the second left tapered sleeve 321 is attached to the end face of the second right tapered sleeve; the first spindle connecting piece 313 is arranged inside the spindle cavity formed by the first left tapered sleeve 311 and the first right tapered sleeve 312 to form a spindle mortise and tenon connection, wherein the size of the spindle cavity just matches the size of the first spindle connecting piece 313; the second spindle connecting piece 323 is arranged inside the spindle cavity formed by the second left tapered sleeve 321 and the second right tapered sleeve 322 to form a spindle mortise and tenon connection; so that the connecting piece 300 tightly connects the first component 100 and the second component 200 together.

[0068] In some embodiments, the member and the node area member are one of a square tube, a rectangular tube, or a circular tube, and the material is one of steel, aluminum alloy, or carbon fiber. As Figure 3 shown, the first member 100 and the second member 200 are square tubes. Of course, they can also be circular tubes or even rectangular tubes. At the same time, the external shape of the first left tapered sleeve 311 also corresponds to a square, a circle, or a rectangle to facilitate the connection between the first left tapered sleeve 311 and the first member 100; the shape of the node area member 330 is the same as that of the first member 100 and the second member 200;; the first right tapered sleeve 312, the second left tapered sleeve 321, and the second right tapered sleeve 322 have the same structure as the first left tapered sleeve 311.

[0069] As Figure 5 shown, the first left tapered sleeve 311 includes: a tapered sleeve body 3111 and a tapered sleeve outer edge 3112; the tapered sleeve body 3111 is a sleeve structure with a hollow half-prismatic cavity in the middle; the tapered sleeve outer edge 3112 is an ear-shaped outer edge provided at one end of the tapered sleeve body 3111. The diameter of the half-prismatic cavity of the tapered sleeve body 3111 gradually decreases from one end face of the tapered sleeve body 3111, that is, the end face of the tapered sleeve convex ring 3113, to the other end face of the tapered sleeve body 3111.

[0070] As Figure 6 shown, the first left tapered sleeve 311 further includes a tapered sleeve convex ring 3113; the tapered sleeve convex ring 3113 is a protruding annular structure provided on the end face of the tapered sleeve outer edge 3112. The setting of the tapered sleeve convex ring 3113 is to prevent interference between the first left tapered sleeve 311 and the first right tapered sleeve 312 and to play a positioning role at the same time.

[0071] In some specific embodiments, as Figure 7 shown, the outside of the first left tapered sleeve 311 is a square and the inside is a hollow steel pipe; the tapered sleeve outer edge 3112 is a hollow annular structure with a square outside and a circular shape concentric with the tapered sleeve body 3111 inside. The tapered sleeve outer edge 3112 and the tapered sleeve body 3111 can be integrally formed or welded together.

[0072] Among them, the first right tapered sleeve 312, the second left tapered sleeve 321, and the second right tapered sleeve 322 have the same structure as the first left tapered sleeve 311.

[0073] According to the above solution, further, as Figure 8As shown, the outer shape of the first fusiform connecting member 313 is a fusiform structure with a larger middle and smaller ends. The material of the first fusiform connecting member 313 is one of steel, aluminum alloy, or carbon fiber. The second fusiform connecting member 323 has the same structure as the first fusiform connecting member 313. The first fusiform connecting member 313 is a fusiform structure that is solid or hollow inside. The first fusiform connecting member 313 is preferably a hollow fusiform structure, which reduces weight and has good economic effects, thereby being able to reduce the self-weight of the overall structure, reduce the cross-sectional size of structural members, and achieve better economic effects.

[0074] In some specific embodiments, the first left conical sleeve 311, the first right conical sleeve 312, the second left conical sleeve 321, and the second right conical sleeve 322 have the same dimensions, with a length of 40 - 200 mm, and the specific dimensions are determined according to the force requirements. The first fusiform connecting member 313 and the second fusiform connecting member 323 are centrosymmetric structures and have the same dimensions, with a length of 80 - 400 each. The sum of the lengths of the first left conical sleeve 311 and the first right conical sleeve 312 is the same as that of the first fusiform connecting member 313, and the sum of the lengths of the second left conical sleeve 321 and the second right conical sleeve 322 is the same as that of the second fusiform connecting member 323. The length of the node area member 330 is greater than the sum of the lengths of the first right conical sleeve 312 and the second left conical sleeve 321. There is a gap of 10 mm - 200 mm between the first right conical sleeve 312 and the second left conical sleeve 321. When the gap size meets the condition that each connecting component in the node does not interfere, reducing the gap size will correspondingly reduce the size of the node area member 330, and the node weight and node cost will be reduced accordingly, and the node design will be more reasonable.

[0075] In summary, the first fusiform connecting member and the second fusiform connecting member are arranged in the fusiform cavity formed by two conical sleeves to form a fusiform mortise and tenon connection, which can be applied to the connection of large-span arched structures. The structure is simple and ingenious, the installation is convenient, and the precision is high.
