[0030] Example

[0031] like Figure 1-7 As shown, the present embodiment provides a modular horizontal connection joint of a steel structure, comprising an extended groove cylindrical column 1, a thin locking cover 2, a sliding limit assembly 3, a sliding limit locking bolt 4, a high position nut 5 and a retracted cylindrical column 6, wherein the extended groove cylindrical column 1 and the retracted cylindrical column 6 are both processed in the factory, and an arc-shaped groove 17 is arranged on the extended groove cylindrical column 1, and the retracted cylindrical column 6 is a hollow structure with a cylindrical groove 18 in the middle, and the size of the extended groove cylindrical column 1 matches that of the cylindrical groove 18, and the extended groove cylindrical column 1 is inserted and connected to the retracted cylindrical column 6 through the thin locking cover 2, the sliding limit assembly 3, the sliding limit locking bolt 4 and the high position nut 5.

[0032] The sliding limit locking bolt 4 is arranged opposite to the retracted cylindrical column 6, and the lower end of the sliding limit locking bolt 4 is fixedly connected to the retracted cylindrical column 6 by machining, and the sliding limit assembly 3 is connected to the sliding limit locking bolt 4 by inserting through the inner wall groove of the sliding limit assembly 3 and the protruding part of the outer wall of the sliding limit locking bolt 4. Specifically, the sliding limit assembly 3 includes four groups of arc plates 7 with the same structure, the upper end surface of the arc plate 7 is provided with a first cylindrical steel pipe 8, the upper end of the inner wall of the arc plate 7 is provided with an arc protrusion 9, and the inner wall of the arc plate 7 is provided with a circular groove 10; the upper end of the sliding limit locking bolt 4 is provided with four groups of bolt blocks 11 and four groups of second cylindrical steel pipes 12, the four groups of bolt blocks 11 are all provided with first bolt holes 13, and the four groups of second cylindrical steel pipes 12 are inserted into the four groups of circular grooves 10, so as to realize the plug-in connection between the sliding limit locking bolt 4 and the sliding limit assembly 3.

[0033] The thin lock cover 2 is connected to the sliding limit assembly 3 by inserting up and down. Specifically, the thin lock cover 2 is provided with four limit grooves 14 and four second bolt holes 15, and the first cylindrical steel pipe 8 is inserted into the limit groove 14 to realize the plug-in connection between the thin lock cover 2 and the sliding limit assembly 3. The thin lock cover 2, the sliding limit device and the sliding limit lock bolt 4 are connected by four bolts penetrating the first bolt hole 13 and the second bolt hole 15.

[0034] The lower end of the sliding limit lock bolt 4 is provided with a thread and is rotatably connected to the high-position nut 5. A drag hole 16 is provided on the outer side wall of the high-position nut 5 to facilitate manual rotation of the high-position nut 5 to the limit state, and then the tightening device is rotated by a tool.

[0035] Working principle: When in use, the sliding limit lock bolt 4 is welded to the inward-retracted cylindrical column 6, and then the high-position nut 5 is put on, and the sliding limit assembly 3 and the thin lock cover 2 are spliced ​​and inserted in sequence, and then the bolt is inserted into the bolt hole to fix it. At this time, the sliding limit assembly 3 and the sliding limit lock bolt 4 are only connected by plug-in, and are in a relatively loose state. Then the extended groove cylindrical column 1 is placed therein so that the groove of the extended groove cylindrical column 1 is engaged with the arc protrusion 9 of the sliding limit assembly 3, and then the high-position nut 5 is rotated to achieve locking. In the process of tightening the high-position nut upward, an inward thrust is given to the sliding limit assembly 3, thereby achieving a close combination of the second cylindrical steel pipe 12 and the circular groove 10. At this time, the thrust will also drive the first cylindrical steel pipe 8 to move from back to front along the limit groove 14. When disassembling, the high-position nut 5 can be rotated in the opposite direction to achieve loosening.
