[0023] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0024] Example

[0025] like Figure 1-4 As shown, a modular horizontal connection joint of a steel structure includes an I-beam 1, a steel ball self-locking connection device 2 and an electromagnetic connection head 3. The upper surface and the lower surface of the connection end of the I-beam 1 are both provided with a plurality of hemispherical grooves 4, and the number of the hemispherical grooves 4 is three and they are respectively located at the three corners of the triangle. One end of the steel ball self-locking connection device 2 is fixedly connected to the I-beam 1 through an upper positioning component 5 and a lower positioning component, and the other end of the steel ball self-locking connection device 2 is fixedly connected to the electromagnetic connection head 3 through a fixing member.

[0026] A positioning hole 6 is provided on the top surface of the steel ball self-locking connection device 2 at one end away from the I-beam 1, a boss 7 is provided on the inner side wall of the positioning hole 6, and an electromagnet 8 is provided at the bottom end of the positioning hole 6. A spring screw 9 is provided in the positioning hole 6, and the spring screw 9 includes a fixed seat 91 and a movable rod 92. The fixed seat 91 is overlapped on the boss 7, and the movable rod 92 is located in the center hole of the fixed seat 91. A convex ring 93 located in the inner cavity of the fixed seat 91 is fixedly connected to the movable rod 92, and the bottom end of the movable rod 92 is made of magnetic metal. A second spring 94 is provided between the convex ring 93 and the bottom surface of the inner cavity, and the second spring 94 is used to provide the movable rod 92 with power to rise and reset when the electromagnet 8 is powered off. The electromagnet 8 and the electromagnetic connector 3 are both connected to the external power supply through the wire 10 pre-buried in the steel ball self-locking connection device 2.

[0027] The steel ball self-locking connection device 2 comprises an integrally connected top plate 201 and a right-angle bent plate 202, one end of the top plate 201 and the right-angle bent plate 202 form a connection groove corresponding to the I-beam 1. The inner wall top surface and the inner wall bottom surface of the connection groove are respectively provided with slots 11 adapted to the top surface and bottom surface structure of the I-beam 1, and the outer wall side surface of the connection groove and the electromagnetic connector 3 are connected by bolts 12.

[0028] The upper positioning assembly and the lower positioning assembly are respectively arranged corresponding to the hemispherical groove 4 on the upper surface of the I-beam 1 and the hemispherical groove 4 on the lower surface of the I-beam 1, and both the upper positioning assembly and the lower positioning assembly include a positioning groove 51 and a locking cover 52. The positioning groove 51 is located on the steel ball self-locking connection device 2, and one end of the positioning groove 51 close to the I-beam 1 is provided with a long strip groove 13 and two first springs 14 parallel to each other, and the other end of the positioning groove 51 is provided with a circular through hole corresponding to the hemispherical groove 4. A positioning steel ball 15 is arranged in the circular through hole, and the positioning steel ball 15 is adapted to connect with the hemispherical groove 4.

[0029] The steel ball self-locking connection device 2 is slidably connected with the inner folding edge of the locking cover 52 through the sliding groove 16. The sliding groove 16 corresponding to the locking cover 52 in the lower positioning assembly is equal to the length of the top plate 201. The length of the sliding groove 16 corresponding to the locking cover 52 in the lower positioning assembly has the following requirements: when the inner folding edge of this locking cover 52 slides to the end of the sliding groove 16, the locking groove 18 on the locking cover 52 just moves to the top of the spring screw 9 on another steel ball self-locking connection device 2, so as to facilitate the positioning between the spring screw 9 and the locking groove 18 on another steel ball self-locking connection device 2. A fixing screw 17 is provided on the top surface of the locking cover 52, and a locking groove 18 for inserting and plugging the spring screw 9 on another steel structure modular horizontal connection joint, a protrusion for pressing and positioning the steel ball 15, and a pressing block 19 for fixing the locking cover 52 are provided on the inner side surface of the top surface of the locking cover 52. An assembly groove 20 corresponding to the first spring 14 is provided on the protrusion, and a gentle slope surface 21 is provided on the end of the protrusion away from the I-beam 1. The pressing block 19 is provided with a guide block 22 extending into the long strip groove 13 , and the pressing block 19 is threadedly connected to the fixing screw 17 .

[0030] The convenient modular assembly and disassembly are as follows: during assembly, the connecting ends of the two I-beams 1 are respectively inserted into the slots 11 of a steel ball self-locking connection device 2, and during insertion, the upper positioning assembly on one steel ball self-locking connection device 2 and the lower positioning assembly on the other steel ball self-locking connection device 2 are located on the same horizontal plane. After insertion, the positioning steel balls 15 in the upper positioning assembly and the lower positioning assembly fall into the hemispherical groove 4 of the I-beam 1. Then, the iron core and the electromagnetic connector 3 of the steel ball self-locking connection device 2 are connected to the power supply through the wire 10. After power is turned on, the spring screw 9 descends and adsorbs on the electromagnet 8. The electromagnetic connector 3 generates magnetic force to dock the steel ball self-locking connection devices 2 on the two I-beams 1, and then the four locking covers 52 on the two steel ball self-locking connection devices 2 are pushed against each other. When pushing, first push the locking cover 52 in the lower positioning assembly to the end position of the slide groove 16, so that the locking groove 18 on the locking cover 52 is opposite to the spring screw 9 on the other steel ball self-locking connection device 2, and then cut off the power, so that the spring screw 9 is pushed upward under the action of the second spring 94 and falls into the locking groove 18 on the other steel ball self-locking connection device 2, and finally push the locking cover 52 in the upper positioning assembly to make it against the other locking cover 52. After the pushing is completed, the protrusion on the locking cover 52 presses the positioning steel ball 15 into the hemispherical groove 4, and then the fixing screw 17 is tightened to prevent the locking cover 52 from resetting due to the action of the first spring 14, and the entire connection structure is completely locked; when disassembling, only power is required, the spring screw 9 is adsorbed downward and disengaged from the locking groove 18, so that the two steel ball self-locking connection devices 2 are unlocked, and the fixing screw 17 is loosened, so that the locking cover 52 is reset under the action of the first spring 14. At this time, the protrusion on the locking cover 52 is removed from the positioning steel ball 15, and the steel ball self-locking connection device 2 can be pulled out from the I-beam 1 to complete the disassembly.

[0031] Therefore, the present invention adopts a modular horizontal connection joint of the steel structure with the above structure, which has a simple fixing method and can realize convenient modular assembly and disassembly, and can also realize large-scale modular production of steel ball self-locking connection devices, electromagnetic connection heads and extended perforated beams.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
