Figure 5 , Figure 5 This is a perspective view of the positioning and protective part of the present invention; please refer to... Figure 6 , Figure 6 This is the invention Figure 4 Enlarged view of point A in the middle, as shown Figures 1-6 As shown, the present invention provides a steel structure connection node adjustment mechanism, comprising: a main steel beam 1, a plurality of secondary steel beams 2 arranged in an array between two main steel beams 1, both the main steel beams 1 and the secondary steel beams 2 being H-beams in the prior art, a connection reinforcement part 3 disposed between the secondary steel beams 2 and the main steel beams 1, and a sliding support part 4 disposed at the lower end of the secondary steel beams 2; both the sliding support part 4 and the connection reinforcement part 3 are made of steel.

[0039] The sliding support 4 can abut against the main steel beam 1, with the abutment located at the inner bottom end.

[0040] Pushing the secondary steel beam 2 allows the secondary steel beam 2 to be displaced via the sliding support part 4, thereby adjusting the secondary steel beam 2 to the position of the main steel beam 1;

[0041] The connecting reinforcement part 3 is used to fasten the main steel beam 1 and the secondary steel beam 2. Specifically, in the prior art, after the main steel beam 1 is erected, the connection node between the secondary steel beam 2 and the main steel beam 1 has excessive adjustment resistance in a confined space. The adjustment process remains unchanged, and the welding after adjustment lacks a fixing effect, resulting in poor stability. Compared with the prior art, the present invention provides a sliding support part 4, which can be detached and connected to the secondary steel beam 2. Through the temporary connection between the sliding support part 4 and the main steel beam 1, the sliding support part 4 replaces the friction between the secondary steel beam 2 and the main steel beam 1, thereby reducing friction. With minimal resistance, the secondary steel beam 2 can move smoothly and quickly in a limited space to adjust its connection with the main steel beam 1. Afterward, the sliding support 4 can be disassembled from the main steel beam 1 without interfering with further connection work between the main steel beam 1 and the secondary steel beam 2. The device is also equipped with a connecting reinforcement 3, which allows the main steel beam 1 and the secondary steel beam 2 to be stably fixed, providing good assistance for welding between the two and making the welding work more effective. The main steel beam 1 and the secondary steel beam 2 will not vibrate or displace significantly during welding or weld seams.

[0042] Optionally, the sliding support part 4 includes a positioning and protection part 41 disposed at the corner of the secondary steel beam 2, an auxiliary part 42 disposed inside the positioning and protection part 41, and two sets of sliding parts 43 disposed at the bottom and side of the positioning and protection part 41.

[0043] The sliding part 43 of the two groups can abut against the side end and bottom end of the main steel beam 1. Specifically, the positioning protection part 41 can fasten the secondary steel beam 2 and the sliding support part 4, the auxiliary part 42 can adjust the position of the secondary steel beam 2 on the sliding support part 4, and the sliding part 43 can reduce the friction force when the sliding support part 4 and the secondary steel beam 2 are in frictional contact with the main steel beam 1, so that the secondary steel beam 2 will not collide with the side of the main steel beam 1 or the inner bottom surface of the main steel beam 1. The collision and friction force can be reduced by friction of the sliding support part 4.

[0044] Optionally, the positioning protection part 41 includes a rectangular sleeve 411 arranged at the corner of the secondary steel beam 2, a threaded hole 412 arranged on one side of the rectangular sleeve 411, and a fastening bolt 413 inserted through the threaded hole 412 and abutting against the secondary steel beam 2. Specifically, the fastening bolt 413 can approach or move away from the secondary steel beam 2 by screwing in the threaded hole 412. When the rectangular sleeve 411 is attached to the corner of the secondary steel beam 2, it can protect the corner of the secondary steel beam 2 from being damaged. Therefore, the fastening bolt 413 can abut against the secondary steel beam 2 tightly and maintain this state, so that the connection between the rectangular sleeve 411 and the secondary steel beam 2 is firm, and this state can be quickly released by reversing the rotation of the fastening bolt 413.

[0045] Optionally, the sliding part 43 includes a hemispherical shell 431 arranged on the rectangular sleeve 411, and a rolling ball 432 arranged in the hemispherical shell 431.

[0046] The rolling ball 432 is used to roll on the main steel beam 1. Specifically, two hemispherical shells 431 are arranged on the bottom surface and the side surface of the rectangular sleeve 411. The inner diameter of the hemispherical shell 431 is arranged to be able to accommodate the rolling of the rolling ball 432, but to ensure that the rolling ball 432 cannot be separated. The rolling ball 432 can roll in all directions in the hemispherical shell 431 to cooperate with the forward and backward movement, left and right movement, and lifting movement of the secondary steel beam 2 on the main steel beam 1, effectively protecting the safety of its work, and allowing the secondary steel beam 2 to move in all directions to achieve the effect of friction saving.

[0047] Optionally, a plurality of strip-shaped holes 5 are arranged in a linear shape on the middle section of the main steel beam 1.

[0048] The connecting reinforcing part 3 comprises an angle code reinforcing rib 31 arranged at the included angle between the secondary steel beam 2 and the main steel beam 1, a steel backing plate 32 arranged at the parallel position of one end of the angle code reinforcing rib 31 and adhered to one side of the main steel beam 1, a first bolt 34 penetrating the angle code reinforcing rib 31, the strip-shaped hole 5 and the steel backing plate 32 in sequence and connected with a nut, and a second bolt 33 penetrating the angle code reinforcing rib 31 and the secondary steel beam 2 in sequence and connected with a nut. Specifically, when the secondary steel beam 2 needs to be adjusted in position, a flexible selection requirement is needed. When the secondary steel beam 2 no longer needs to be adjusted at the connecting joint position of the main steel beam 1, the angle code reinforcing rib 31 is adhered at the included angle between the secondary steel beam 2 and the main steel beam 1. The main steel beam 1 is connected through the steel backing plate 32, the first bolt 34 and the nut, and the secondary steel beam 2 is connected through the second bolt 33 and the nut. In this way, the main steel beam 1, the secondary steel beam 2 and the angle code reinforcing rib 31 are connected as a whole. At this time, when the welding operation or the welding operation is performed, the connecting joint of the main steel beam 1, the secondary steel beam 2 and the angle code reinforcing rib 31 is stable and will not deviate.

[0049] Optionally, the positioning protection part 41 further comprises a plurality of insertion blocks 414 arranged at the bottom end of the rectangular sleeve 411, a protection plate 415 arranged at one side of the rectangular sleeve 411, and a plurality of insertion slots arranged at the bottom end of the protection plate 415.

[0050] The plurality of insertion blocks 414 can be inserted into the plurality of insertion slots. Specifically, the protection plate 415 acts on the plurality of insertion blocks 414 and the rectangular sleeve 411 to form an insertion combination structure. After the structure combination, a coverless box body with one missing surface can be formed. The missing surface direction is the insertion direction of the secondary steel beam 2. The four surfaces at the corners of the secondary steel beam 2 can be protected. The insertion combination structure can also be quickly separated. The secondary steel beam 2 can be separated from the protection plate 415 and the rectangular sleeve 411 in the direction, which is beneficial to the repeated use of the rectangular sleeve 411 and the adjustment work of the secondary steel beam 2 and the main steel beam 1.

[0051] Optionally, the auxiliary part 42 comprises a plurality of rollers 421 arranged inside the side section of the rectangular sleeve 411.

[0052] The plurality of rollers 421 can abut against the secondary steel beam 2.

[0053] The plurality of rollers 421 can frictionally rotate the secondary steel beam 2. Specifically, when the secondary steel beam 2 needs to be separated from the rectangular sleeve 411, the rectangular sleeve 411 can be subjected to a force in the direction opposite to that of the protection plate 415. At this time, the force can drive the rollers 421 to frictionally rotate the bottom of the secondary steel beam 2, so that the secondary steel beam 2 can be conveniently separated from the rectangular sleeve 411.

[0054] Optionally, the auxiliary part 42 further comprises a plurality of circular grooves 422 arranged at the inner bottom end of the rectangular sleeve 411, and a plurality of support shafts 423 rotatably arranged in the plurality of circular grooves 422;

[0055] The plurality of support shafts 423 abut against the plurality of rollers 421, and the rollers 421 can drive the support shafts 423 to rotate. Specifically, the plurality of circular grooves 422 provide rotation space and support space for the plurality of support shafts 423, saving the space waste of the rectangular sleeve 411. The plurality of support shafts 423 play a supporting role for the rollers 421, avoiding damage of the rollers 421 due to excessive gravity of the secondary steel beam 2, and allowing the gravity to be effectively dispersed.
