[0002] A steel structure node refers to the part where the various steel components that make up a steel structure are connected together. It is an important component of the steel structure system and plays a vital role in the overall performance and safety of the steel structure.

[0003] After searching, the announcement number CN218970271U discloses a steel structure connection node. When the connection node connects the I-shaped steel and the steel beam, the connecting protrusion and the connecting recess are plugged into the plug-in block, and the plug-in block is inserted into the slot to lock the position of the connecting protrusion and the connecting recess. At this time, the first connecting through hole is connected to the second connecting through hole, which reduces the time required for alignment between the I-shaped steel and the steel beam and improves the installation speed.

[0004] However, due to the small installation space of the side wall of the column body, the number of beams that can be connected to the column is small, and the overall width of the connected beams is small, which makes it impossible for the column to connect and position multiple beams. Utility Model Content

[0005] In view of the above problems existing in the existing steel structure node connection structure, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a steel structure node connection structure, which solves the problem that the number of beams that can be connected to the column is small and the overall width specification of the connected beams is small due to the small installation space of the side walls around the column body.

[0009] Preferably, two symmetrically arranged positioning bolts are threadedly penetrated at both upper and lower ends of the outer wall of the steel column, and a plurality of threaded connection holes arranged at intervals are provided inside the upper and lower slide plates.

[0010] Preferably, the connecting member includes two symmetrically arranged baffles, and support rods are fixedly penetrated inside the upper slide plate, the lower slide plate and the expansion plate. The two baffles are respectively arranged on both sides of the expansion plate and are rotatably mounted on the outer sides of the two adjacent support rods.

[0011] Preferably, the connecting sleeve is arranged in a U shape.

[0012] Furthermore, a plurality of transverse reinforcement rods which are arranged symmetrically around the upper end of the steel column are fixedly provided on the outer wall, and the ends of the transverse reinforcement rods are fixedly connected to the inside of the connecting sleeve.

[0013] Preferably, both ends of the transverse reinforcement rod are fixed to the connecting sleeve and the steel column by welding.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a steel structure node connection structure.

[0026] The utility model provides Figure 1-4 A steel structure node connection structure shown includes a steel column 1, and a plurality of upper slots 2 and lower slots 3 are respectively provided at the upper and lower ends of the steel column 1 in a symmetrically arranged manner. An upper slide plate 4 and a lower slide plate 5 are respectively slidably penetrated inside the upper and lower slots 2 and the lower slots 3. Two symmetrically arranged positioning bolts 11 are threadedly penetrated at both upper and lower ends of the outer wall of the steel column 1. A plurality of threaded connection holes 12 are respectively provided inside the upper and lower slide plates 4 and the lower slide plates 5. An expansion plate 6 is provided between two adjacent upper slide plates 4 and lower slide plates 5 through a connecting piece. A connecting sleeve 7 is provided on the outer side of two adjacent expansion plates 6. The connecting sleeve 7 is U-shaped. Two symmetrically arranged fixing rods 8 are fixedly provided on the inner wall of the connecting sleeve 7. The expansion plate 6 is rotatably sleeved on the outer side of the fixing rod 8. A mounting plate 9 is fixedly provided on the outer wall of the connecting sleeve 7. A mounting hole 10 is provided inside the mounting plate 9.

[0027] When it is necessary to connect multiple beams through the steel column 1, the upper slide plate 4 and the lower slide plate 5 can be moved through the upper slot 2 and the lower slot 3 to make the upper slide plate 4 and the lower slide plate 5 close to each other. At this time, under the rotation support of the connecting piece, the two adjacent expansion plates 6 can be rotated, and the connecting sleeve 7 and the mounting plate 9 can be moved laterally under the rotation cooperation of the fixing rod 8. After the mounting plate 9 is moved laterally, the position of the upper slide plate 4 and the lower slide plate 5 can be fixed by the positioning bolts 11 and the threaded connection holes 12 to ensure that the setting position of the mounting plate 9 is fixed. When multiple mounting plates 9 have completed the movement, the position between two adjacent mounting plates 9 can be expanded. At this time, a larger width range and a larger number of steel beams can be connected and fixed, ensuring the connection versatility of the steel structure node.

[0028] In order to enable the upper slide plate 4, the lower slide plate 5 and the expansion plate 6 to rotate stably, as shown in FIG. Figure 1 and Figure 3As shown, the connecting member includes two symmetrically arranged baffles 13, and support rods 14 are fixedly penetrated inside the upper slide plate 4, the lower slide plate 5 and the expansion plate 6. The two baffles 13 are respectively arranged on both sides of the expansion plate 6 and are rotatably sleeved on the outer sides of two adjacent support rods 14.

[0029] With the rotation cooperation of the two baffles 13 and the support rod 14 on the same side, the expansion plate 6 can rotate stably when the upper slide plate 4 and the lower slide plate 5 are approaching or separating, so as to facilitate the pushing out of the connecting sleeve 7 and the mounting plate 9.

[0030] In order to ensure the connection stability of the steel beam after the installation plate 9 is pushed out, Figure 1 As shown, a plurality of transverse reinforcement rods 15 arranged symmetrically around the upper end of the steel column 1 are fixedly provided, and the ends of the transverse reinforcement rods 15 are fixedly connected to the inside of the connecting sleeve 7, and the two ends of the transverse reinforcement rods 15 are fixed to the connecting sleeve 7 and the steel column 1 by welding.

[0031] After the mounting plate 9 is moved laterally and connected to the steel beam, the transverse reinforcement rod 15 can be selected according to the distance between the mounting plate 9 and the steel column 1, and the transverse reinforcement rod 15 can be set between the connecting sleeve 7 and the steel column 1 to provide firm support for the connected steel beam, thereby improving the connection stability of the steel structure node.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
