The guide protrusion 31 is in guiding fit with the guide hole 32, the guide hole 32 may be a through hole, a groove, or a tubular structure, and the geometric centerline of the guide hole 32 extends in the same direction as the splicing direction. If the guide protrusion 31 approaches the guide hole 32, the guide hole 32 limits the guide protrusion 31, so that the guide protrusion 31 moves only in the splicing direction. Similarly, the guiding hole 32 approaches to the guiding protrusion 31, and the guiding protrusion 31 limits the guiding hole 32, so that the guiding hole 32 only moves along the splicing direction. For example, the guide protrusion 31 is provided on the first spliced end of the first girder 1, the guide hole 32 is provided on the second spliced end of the second girder 2, and the guide protrusion 31 cooperates with the guide hole 32 to restrict the degree of freedom in the Y and Z directions so that the second girder 2 approaching the first girder 1 moves only in the X direction.

Further, in an embodiment, the guide protrusion 31 may be convex, and correspondingly, the guide hole 32 is configured as a groove to be fitted with the protrusion; in an embodiment, the guide protrusion 31 may be in the shape of a cross key, and correspondingly, the guide hole 32 is configured as a cross recess, as shown in fig. 5. Specifically, the first splicing end is a first connection plate 11, and the second splicing end is a second connection plate 21. The cross key is constructed on one side, facing the second connecting plate 21, of the first connecting plate 11, meanwhile, the cross groove is correspondingly constructed on one side, facing the first connecting plate 11, of the second connecting plate 21, the cross key and the cross groove achieve a guiding effect on splicing through embedding of key grooves, and the cross key is simple in structure and convenient to process; in an embodiment, as shown in fig. 6 and 7, the second splicing end is configured as a guide protrusion 31, the guide tool is a guide hole 32, the guide tool is sleeved on the first splicing end, specifically, the guide tool includes a guide sleeve 41, a plurality of rolling elements 42 (e.g., balls or rollers) are disposed on an inner side of a cylindrical wall of the guide sleeve 41, the guide sleeve 41 can be sleeved on respective first ends of the first girder 1 and the second girder 2, and the rolling elements 42 can be located between the first girder 1 and the second girder 2 and the inner side of the cylindrical wall, when the splicing assembly is performed, the first girder 1 and the second girder 2 are respectively inserted into cylindrical openings at two ends of the guide sleeve 41 and are close to each other, thereby effectively facilitating the splicing and reducing the splicing time.

The following embodiments are described in the above-described configurations, and of course, in some cases, the arrangement parts of the two may be reversed without adversely affecting the specific orientation.

As a specific implementation, the guide projection 31 includes a guide portion 312, and the area of the cross section of the guide portion 312 along the protruding direction (i.e., along the direction from the first splicing end to the second splicing end) is gradually reduced to facilitate the insertion of the guide projection 31 into the guide hole 32.

In a specific embodiment, the guiding portion 312 may have a truncated cone shape, a hemispherical shape, a semi-ellipsoidal shape, or the like, wherein the truncated cone shape is preferred, as shown in fig. 2. The arrangement is simple in process and convenient to process.

As a specific implementation manner, the guide protrusion 31 further includes a matching portion 311, the matching portion 311 connects the first splicing end (the first connecting plate 11) and the guide portion 312, the cross section of the matching portion 311 is the same as the maximum cross section of the guide portion 312, and the matching portion 311 is in plug-in fit with the guide hole 32.

As shown in fig. 4, it should be noted that the outer contour of the fitting portion 311 is substantially the same as the inner contour of the guide hole 32, that is, a small gap exists between the fitting portion 311 and the guide hole 32 for facilitating the fitting. Meanwhile, the matching part 311 is in inserting fit with the guide hole 32, the matching part 311 plays a bearing role for the second girder 2, and the matching part 311 is equivalent to support a second splicing end of the second girder 2, so that the threaded fastening or positioning between the matching part 311 and the second splicing end is facilitated.

In a specific implementation manner, considering that the overall weight of the first girder 1 and the second girder 2 is large, the large-volume and large-mass engaging portion 311 is required, and the orthographic projection of the engaging portion 311 on the first connection plate 11 occupies 50% to 80% of the area of the first connection plate 11, so that the guiding function of the guide portion 312 and the guide hole 32 is better exerted, and high reliability is included.
