[0001] The invention relates to a building structure, in particular to a steel structure connection node. Background Art

[0002] Steel structures are widely used in various building structures due to their high strength, lightweight, fast construction, and excellent seismic resistance. Traditional steel structure connection nodes are typically connected using bolts, welding, or riveting. While these connection methods can meet connection requirements to a certain extent, they have some shortcomings. Although welded connections have high structural strength, they require professional skills during construction and are difficult to disassemble, which is not conducive to subsequent maintenance and replacement. Bolting and riveting have solved some of the problems of welded connections to a certain extent, but they still suffer from complex installation and low efficiency. Summary of the Invention

[0008] Furthermore, an elastic pad is provided in the upper module column, and the elastic pad is located below the bushing. The sum of the thickness of the elastic pad and the connecting member is less than the thickness of the bushing.

[0009] Furthermore, a rod guide box is provided on the outer side of the upper end of the connecting piece, a rod is passed through both the rod guide box and the connecting piece, and a socket for the rod to enter is opened on the upper module column.

[0010] Furthermore, the self-locking hook includes two hooks symmetrically arranged inside the lower module column and a spring connected between the two hooks. The hook includes two vertical rods hinged at the lower end to the inner wall of the lower module column and a strip board spanning the two vertical rods.

[0011] Furthermore, the distance between the two strips is greater than the width of the lower end of the connecting member, and smaller than the distance between the outer side walls below the two grooves of the connecting member.

[0012] Furthermore, an unlocking rope is provided on the outer side of the self-locking hook, an unlocking hole for the unlocking rope to pass through is opened on the lower module column, and an unlocking ring is connected to the outer end of the unlocking rope.

DETAILED DESCRIPTION

[0026] like Figure 1 and Figure 2 As shown, the present invention includes an upper modular column 1 and a lower modular column 2. A weight block 12 and a connector 14 are disposed within the upper modular column 1. The connector 14 is disposed at the bottom of the upper modular column 1. The weight block 12 is positioned above the connector 14, and a groove is disposed on the outer side of the connector 14. The lower portion of the weight block 12 is adapted to the inner wall dimensions of the groove of the connector 14, while the upper portion of the weight block 12 matches the upper inner wall dimensions of the connector 14. A slope is disposed between the lower and upper portions of the weight block 12. The weight block 12 has a certain mass, which is used to provide pressure to prevent the connector 14 from sliding downward and to maintain stability after the upper and lower modular columns 1 and 2 are connected. A lower limit plate 21 and a self-locking hook 22 are provided at the top inside the lower module column 2. When the weight block 12 falls, the weight block 12 first falls into the connecting piece 14, and then the weight block 12 and the lower part of the connecting piece 14 fall into the lower module column 2, and stop after the lower end of the connecting piece 14 is blocked by the lower limit plate 21. At this time, the upper end of the self-locking hook 22 is stuck in the groove of the connecting piece 14, locking and fixing the connecting piece 14, thereby realizing the connection between the upper connecting piece 14 and the lower module column 2.

[0027] A limiting component for limiting the position of the weight block 12 is provided inside the upper module column 1. The limiting component includes an upper limit plate 11 for limiting the position above the weight block 12 and a limiting rod 13 for limiting the position below the weight block 12. The upper limit plate 11 is provided inside the upper module column 1, and the limiting rod 13 is passed through the upper module column 1. The weight block 12 is located between the upper limit plate 11 and the limiting rod 13, and its up and down movement is restricted by these two components. Both ends of the limiting rod 13 protrude from the upper module column 1. One end of the limiting rod 13 is connected to a pull ring 131, through which the limiting rod 13 can be easily pulled out of the upper module column 1. The other end of the limiting rod 13 is passed through a safety bolt 132 to prevent the limiting rod 13 from slipping off the upper module column 1 during transportation, causing the weight block 12 and the connecting member 14 to fall out of the upper module column 1. Remove the safety bolt 132 before pulling out the limiting rod 13. There are two limiting rods 13 , which jointly support the weight block 12 .

[0028] A bushing 15 is provided within the upper module column 1, positioned between the connector 14 and the upper limit plate 11. The weight 12 is positioned within the bushing 15. An elastic pad 16 is also provided within the upper module column 1, positioned below the bushing 15. The upper end of the connector 14 compresses the elastic pad 16, causing friction between the upper end of the connector 14 and the pad 16 to lock the connector 14 within the upper module column 1. Furthermore, the combined thickness of the elastic pad 16 and connector 14 is less than the thickness of the bushing 15, preventing the weight 12 from interfering with the upper end of the connector 14 during a fall.

[0029] A rod guide box 141 is located on the outer side of the upper end of the connector 14. A rod 142 extends through both the rod guide box 141 and the connector 14. A hole is provided on the side of the rod guide box 141 facing away from the connector 14 for the outer end of the rod 142 to pass through. The inner end of the rod 142 extends flatly into the interior of the connector 14. A receptacle is provided at the lower portion of the upper modular column 1 for the outer end of the rod 142 to enter. After the upper modular column 1 and the lower modular column 2 are connected, the outer end of the rod 142 extends into the receptacle, securing the connector 14 to the upper modular column 1. The inner end of the rod 142 has a sloped surface that matches the slope of the weight block 12. The insertion rod 142 is provided with a ridge, the diameter of which is larger than the size of the insertion hole of the lower module column 2 and also larger than the size of the through-hole of the connector 14 for inserting the insertion rod 142, so that the insertion rod 142 will not fall out of the insertion rod guide box 141. There are two insertion rod guide boxes 141, symmetrically arranged at both ends of the connector.

[0030] The connecting member 14 is U-shaped as a whole, and has two grooves, which are symmetrically arranged on both sides of the connecting member 14. The outer wall below the groove of the connecting member 14 is an inwardly extending inclined surface, and the lower part of the connecting member 14 is an inverted trapezoidal shape to prevent its lower end from interfering with the upper end of the self-locking hook 22 during the connection process.

[0031] The self-locking hook 22 consists of two symmetrically positioned hooks on either side of the interior of the lower modular column 2, and a spring 223 connected between the two hooks. The hooks consist of two vertical rods 221 hinged at their lower ends to the inner wall of the lower modular column 2, and a strip 222 straddling the upper ends of the two vertical rods 221. The strip 222 is designed to engage the groove of the connector 14. A connecting lug 23 is attached to the interior of the lower modular column 2, to which the lower end of the self-locking hook 22 is hinged. Two springs 223 are provided, one between each vertical rod 221 corresponding to the two hooks. The spring 223 ensures that the distance between the upper ends of the two self-locking barbs 22 is greater than the width of the lower end of the connector 14, making it easier for the lower end of the connector 14 to enter between the two self-locking barbs 22; at the same time, it is smaller than the distance between the outer side walls below the two grooves of the connector 14, so that when the lower end of the connector 14 contacts the lower limit plate, the upper ends of the self-locking barbs 22 can be snapped into the grooves of the connector 14 under the tension of the spring 223. The inner side of the strip 222 is provided with an inclined surface, which matches the inclined surface extending outward from the outer side wall below the groove of the connector 14, thereby ensuring that the connector 14 can slide smoothly between the two self-locking barbs 22, and the strip 222 is snapped into the groove using the tension of the spring.

[0032] An unlocking cord 224 is provided on the outside of the self-locking barb 22. An unlocking hole is provided on the top of the lower module column 2 for the unlocking cord 224 to pass through. The unlocking cord 224 is inserted into the unlocking hole, and an unlocking ring 225 is connected to the outer end of the unlocking cord 224. Pulling the unlocking cord 224 outward through the unlocking ring 225 releases the lock of the self-locking barb 22 on the connecting member 14, disconnecting the upper module column 1 from the lower module column 2.

[0033] The lower stopper plates 21 consist of two pieces, providing stable support for the connector 14. They are positioned higher than the connecting lugs 23 and lower than the position of the strips 222 when the self-locking barbs 22 are in the upright position. Furthermore, the width of the lower stopper plates 21 is smaller than the distance between the two uprights 221 of the self-locking barbs 22 to prevent the self-locking barbs 22 from interfering with the lower stopper plates 21 during rotation. The springs 223 are positioned lower than the lower stopper plates 21 to prevent interference with the connector 14.

[0034] A positioning ring 3 is provided between the upper module column 1 and the lower module column 2 . When the upper module column 1 is mounted on the lower module column 2 , the positioning ring 3 ensures accurate alignment and positioning of the two.

[0035] When in use, install the positioning ring 3 on the upper end of the lower module column 2, and then install the lower end of the upper module column 1 on the positioning ring 3. Then pull out the safety bolt 132 and then pull out the limit rod 13. Figure 3As shown, the weight block 12 falls downward into the connector 14. After the inclined surface of the weight block 12 contacts the insertion rod 142, under the action of inertia and gravity, the weight block 12 and the connector 14 slide downward together. Then, the lower end of the connector 14 enters between the two self-locking hooks 22. As the connector 14 slides downward, the lower inclined surface of the connector 14 squeezes the two self-locking hooks 22 on both sides. Figure 4 As shown, when the lower end of the connector 14 contacts the upper end of the lower limit plate 21, the self-locking barb 22, under the tension of the spring, snaps into the groove of the connector 14, completing the connection between the lower module column 2 and the connector 14. Afterwards, the weight block 12 continues to move downward until it contacts the inner bottom of the connector 14. During this downward movement, the weight block 12 presses the insertion rod 142 outward, and the outer end of the insertion rod 142 enters the socket of the upper module column 1, connecting the connector 14 to the upper module column 1.

[0036] Pull the unlocking rope 224 outward to unlock the connection between the self-locking hook 22 and the connector 14, thereby disconnecting the upper module column 1 and the lower module column 2.
