Technical Field

[0001] The utility model relates to a corbel connecting piece for prefabricated buildings, belonging to the field of steel structure buildings. Background Technique

[0002] The hollow column is one of the main components in the corbel connecting piece. A plurality of connecting pieces for connecting cross beams in prefabricated buildings are evenly installed on the outer surface of the hollow column. For a steel structure building with a gable roof at the top, when arranging the hollow column between the edge part of the gable roof at the top of the steel structure building and the cross beam, in order to connect the upper and lower ends of the hollow column with the edge part of the gable roof at the top of the steel structure building and the cross beam respectively, it is necessary to install a plurality of hollow columns with different lengths at the edge part of the gable roof at the top of the steel structure building, that is, the heights of the tops of the hollow columns are the same. Therefore, it is necessary to manufacture hollow columns with different lengths, and the hollow columns with different lengths need to be installed at specific positions, resulting in difficulty in making the hollow columns universal. Therefore, it is necessary to design a parapet structure for a steel structure building that can be universal. Content of the Utility Model

Detailed Embodiment

[0024] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figure 1 , the present utility model provides a technical solution: an assembled building bracket connector, which includes an outer tube 1 with a rectangular cross-section. The upper end of the outer tube 1 is fixedly connected with an upper cover 2. A plurality of upper fixing holes are evenly arranged on the upper surface of the upper cover 2. An inner tube 8 is inserted into the outer tube 1. The cross-section of the inner tube 8 is rectangular. A connecting edge 9 fixedly connected with the inner tube 8 is sleeved at one end of the inner tube 8 away from the end cover 12. A plurality of lower fixing holes are evenly arranged on the upper surface of the connecting edge 9. By installing the connecting edge 9 on the inner tube 8, it is convenient to install the hollow column structure formed by the inner tube 8 and the outer tube 1 on the steel structure building beam.

[0026] Refer to Figures 1-4 , the upper end of the inner tube 8 is fixedly connected with an end cover 12. A screw hole 15 is opened in the middle position of the upper surface of the end cover 12. A screw rod 13 is threadedly connected in the screw hole 15. The upper end of the screw rod 13 is installed in the inner ring of a bearing 14. The outer ring of the bearing 14 is fixedly connected with the upper cover 2. Thus, the rotational connection between the screw rod 13 and the upper cover 2 is realized through the bearing 14. A rectangular hole 17 is opened on the side of the screw rod 13 facing away from the upper cover 2. The rectangular hole 17 is arranged along the length direction of the screw rod 13. A rectangular rod 11 is inserted into the rectangular hole 17. One end of the rectangular rod 11 extends to the outside of the inner tube 8. A handle 10 is fixedly connected to the end of the rectangular rod 11 outside the rectangular hole 17. The handle 10 is perpendicularly arranged with the rectangular rod 11. By inserting one end of the rectangular rod 11 into the rectangular hole 17 on the screw rod 13, the insertion connection between the rectangular rod 11 and the screw rod 13 is realized. After separating the rectangular rod 11 from the screw rod 13, the rectangular rod 11 can be reused multiple times. After the rectangular rod 11 is inserted into the rectangular hole 17, the rectangular rod 11 is used to rotate the screw rod 13. Thus, the length of the inner tube 8 inserted into the outer tube 1 changes. Thus, the length formed by the inner tube 8 and the outer tube 1 increases or shortens, realizing the adjustment of the length of the hollow column structure formed by the outer tube 1 and the inner tube 8 according to its installation position on the herringbone top of the steel structure building, making the hollow column structure formed by the outer tube 1 and the inner tube 8 universal.

[0027] Refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7, vertical upper studs 4 are provided on four side surfaces of the outer tube 1. Both ends of the upper stud 4 are fixedly connected with a first ear 3. The first ear 3 is fixedly connected with the outer tube 1. The first ear 3 serves to connect the upper stud 4 and the outer tube 1. A short connecting block 6 is provided between the two first ears 3. One side surface of the short connecting block 6 is in contact with the outer tube 1. A first vertical hole 21 is formed in the upper surface of the short connecting block 6. The upper stud 4 penetrates through the first vertical hole 21. First nuts 5 are provided on both the upper and lower sides of the short connecting block 6 and are threadedly connected with the upper stud 4. A plurality of first screw holes 15 for threadedly connecting bolts are evenly formed in the surface of the short connecting block 6 facing away from the outer tube 1, so that both first nuts 5 are in contact with the short connecting block 6, thereby restricting the relative position between the short connecting block 6 and the upper stud 4.

[0028] Vertical strip-shaped openings 16 are formed on four side surfaces of the inner tube 8. A long connecting block 7 is inserted into the strip-shaped opening 16. A second vertical hole 22 is formed in the upper surface of the long connecting block 7. A lower stud 20 located inside the inner tube 8 is inserted into the second vertical hole 22. Both ends of the lower stud 20 are fixedly connected with a second ear 19. The second ear 19 is installed on the inner wall of the inner tube 8. Second nuts 18 are provided on both the upper and lower sides of the long connecting block 7 and are threadedly connected with the lower stud 20. A plurality of second screw holes 15 for threadedly connecting bolts are evenly formed in the surface of the long connecting block 7 located outside the inner tube 8, so that both second nuts 18 are in contact with the long connecting block 7, thereby restricting the relative position between the long connecting block 7 and the lower stud 20.

[0029] According to the length of the inner tube 8 inserted into the outer tube 1, adjust the position of the short connecting block 6 along the upper stud 4, and adjust the position of the long connecting block 7 along the lower stud 20, so that the positions of the long connecting block 7 and the short connecting block 6 meet the installation requirements of the bolts for restricting the relative positions of the cross beam, the outer tube 1, and the inner tube 8. Then, use the two first nuts 5 to restrict the relative position between the short connecting block 6 and the upper stud 4, and use the two second nuts 18 to restrict the relative position between the long connecting block 7 and the lower stud 20, so as to realize the adjustment of the installation position of the bolts for restricting the relative positions of the cross beam, the outer tube 1, and the inner tube 8 on the hollow column structure formed by the inner tube 8 and the outer tube 1 as needed.
