[0039] The sliding support part 4 can push down the main steel beam 1, and the push-down position is the inner bottom end, wherein,

[0040] Push the secondary steel beam 2, and the secondary steel beam 2 can be displaced with the assistance of the sliding support part 4, so that the secondary steel beam 2 is adjusted to the position of the main steel beam 1;

[0041] The connection 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 built, the connection node between the secondary steel beam 2 and the main steel beam 1 has too large adjustment resistance in a confined space, the adjustment process remains unchanged, and the welding after the adjustment position lacks a retention effect, and the stability is poor. Compared with the prior art, the present invention is provided with a sliding support part 4, which can be detachably connected with 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 to reduce Less movement resistance allows the secondary steel beam 2 to move smoothly in a limited space and quickly adjust the connection node with the main steel beam 1. Afterwards, the sliding support part 4 and the main steel beam 1 are disassembled without interfering with the further connection work between the main steel beam 1 and the secondary steel beam 2. The device is also provided with a connection reinforcement part 3. The connection reinforcement part 3 can stably fix the main steel beam 1 and the secondary steel beam 2, providing a good auxiliary effect for the welding between the two, so that the welding effect is better, and the main steel beam 1 and the secondary steel beam 2 will not shake or dislocate significantly during welding or welding.

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

[0043] The two groups of sliding parts 43 can respectively resist the side ends and the bottom ends 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 friction contact with the main steel beam 1, so that the secondary steel beam 2 will neither collide with the side surface of the main steel beam 1 nor the inner bottom surface of the main steel beam 1, and the collision and friction force can be reduced by the 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 the secondary steel beam 2 or move away from the secondary steel beam 2 by pushing the thread in the threaded hole 412. When the rectangular sleeve 411 fits the corner of the secondary steel beam 2, it will protect the corner of the secondary steel beam 2 and avoid scratching the corner. Based on this, the fastening bolt 413 can tightly abut against the secondary steel beam 2 and maintain this state, so that the connection state between the rectangular sleeve 411 and the secondary steel beam 2 is firm, and this state can be quickly released by the reverse rotation of the fastening bolt 413.

[0045] Optionally, the sliding portion 43 includes a hemispherical shell 431 disposed on the rectangular sleeve 411, and a ball 432 rollingly disposed in the hemispherical shell 431;

[0046] The ball 432 is used for frictionally rolling the main steel beam 1. Specifically, two hemispherical shells 431 are respectively arranged on the bottom and side surfaces of the rectangular sleeve 411. The inner diameter of the hemispherical shell 431 is set to accommodate the rolling of the ball 432, but to ensure that the ball 432 cannot be separated. The ball 432 can roll in all directions in the hemispherical shell 431 as the friction force is generated, so as to cooperate with the front and rear movement, left and right movement and lifting and lowering movement of the secondary steel beam 2 on the main steel beam 1, effectively protecting its working safety, and allowing the movement and adjustment of the secondary steel beam 2 in all directions to obtain the friction and labor-saving effect.

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

[0048] The connecting reinforcement part 3 includes an angle code stiffening rib 31 arranged at the angle between the secondary steel beam 2 and the main steel beam 1, a steel plate 32 arranged at a parallel position at one end of the angle code stiffening rib 31 and attached to one side of the main steel beam 1, a first bolt 34 inserted through the angle code stiffening rib 31, the strip hole 5 and the steel plate 32 and connected with a nut, and a second bolt 33 inserted through the angle code stiffening rib 31 and the secondary steel beam 2 and connected with a nut. Specifically, the plurality of strip holes 5 facilitate a flexible adjustment of the position of the secondary steel beam 2. According to the selection requirements, when the secondary steel beam 2 no longer needs to be adjusted at the connection node position of the main steel beam 1, the angle code stiffener 31 is selected to fit the angle between the secondary steel beam 2 and the main steel beam 1, and the main steel beam 1 is connected by the steel pad 32, the first bolt 34 and the nut, and the secondary steel beam 2 is connected by the second bolt 33 and the nut. In this way, the main steel beam 1, the secondary steel beam 2 and the angle code stiffener 31 are connected as a whole. At this time, when performing welding operations or welding operations, the connection nodes of the main steel beam 1, the secondary steel beam 2 and the angle code stiffener 31 are stable and will not deviate.

[0049] Optionally, the positioning protection part 41 further includes a plurality of plug blocks 414 disposed at the inner bottom end of the rectangular sleeve 411, a protection plate 415 disposed at one side of the rectangular sleeve 411, and a plurality of slots disposed at the bottom end of the protection plate 415;

[0050] Several of the plug blocks 414 can be plugged into several of the slots. Specifically, the protective plate 415 acts on several of the plug blocks 414 and the rectangular sleeve 411 through several slots to form a plug-in combination structure. After the structure is combined, it can become a coverless box body with one side missing. The direction of the missing side is the insertion direction of the secondary steel beam 2, so that the four sides at the corners of the secondary steel beam 2 can be protected. The plug-in combination structure can also be quickly separated. The secondary steel beam 2 can be separated from the rectangular sleeve 411 from the direction of the protective plate 415, which is conducive to the repeated use of the rectangular sleeve 411 and the adjustment of the other secondary steel beam 2 and the main steel beam 1.

[0051] Optionally, the auxiliary part 42 includes a plurality of rollers 421 disposed on the inner side section of the rectangular sleeve 411;

[0052] Some of the rollers 421 can abut against the secondary steel beam 2;

[0053] Several of the rollers 421 can rub the secondary steel beam 2 to rotate. 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 opposite direction of the protective plate 415. At this time, the force will drive the rollers 421 and the bottom of the secondary steel beam 2 to rub and rotate, making it easy to separate the secondary steel beam 2 from the rectangular sleeve 411.

[0054] Optionally, the auxiliary portion 42 further includes a plurality of circular grooves 422 disposed at the bottom end of the rectangular sleeve 411, and a plurality of supporting shafts 423 rotatably disposed in the plurality of circular grooves 422;

[0055] The support shafts 423 are offset against the rollers 421, and the rollers 421 can drive the support shafts 423 to rotate. Specifically, the circular grooves 422 provide rotation space and support space for the support shafts 423, saving space waste of the rectangular sleeve 411. The support shafts 423 support the rollers 421, preventing the rollers 421 from being damaged by excessive gravity of the secondary steel beam 2, so that the gravity can be effectively dispersed.

[0056] According to another aspect of the present invention, there is provided a method for adjusting a steel structure connection node, comprising:

[0057] The first step is to open a number of strip holes 5 on the erected main steel beam 1, partially cut the horizontal plate parts at the left and right ends of the secondary steel beam 2, insert the set composed of the rectangular sleeve 411 and the protective plate 415 into the vertical plate part of the secondary steel beam 2, and tighten the fastening bolts 413 to fasten the secondary steel beam 2 and the set;

[0058] The second step is to hoist the secondary steel beam 2 by external hoisting equipment so that the secondary steel beam 2 and the kit are located between the two main steel beams 1;

[0059] The third step is to push the secondary steel beam 2 to the position of the main steel beam 1, and stop after reaching the designated position. The two balls 432 rub the main steel beam 1 to rotate in the hemispherical shell 431;

[0060] The fourth step is to fit the angle code stiffening rib 31 and the steel plate 32 on both sides of the main steel beam 1 with the front and back sides of the strip hole 5 as references, and install the angle code stiffening rib 31 and the steel plate 32 on the main steel beam 1 through the connection of the first bolt 34 and the nut. Then, the angle code stiffening rib 31 and the secondary steel beam 2 are fastened by the second bolt 33 inserted through the angle code stiffening rib 31 and the nut. Based on this, the gap between the secondary steel beam 2 and the angle code stiffening rib 31 and the gap between the main steel beam 1 and the angle code stiffening rib 31 are selectively welded.

[0061] Step 5: loosen the fastening bolts 413 away from the secondary steel beam 2, pull out the protective plate 415 to separate it from the rectangular sleeve 411, and separate the plurality of plug blocks 414 from the plurality of slots accordingly;

[0062] The sixth step is to push the rectangular sleeve 411, and the roller 421 rotates to drive the support shaft 423 to rotate and separate from the secondary steel beam 2 by friction and rolling, so as to wait for the next time when the secondary steel beam 2 is adjusted to the position of the main steel beam 1.

[0063] In another embodiment, before the fourth step, a plurality of first circular holes for inserting the second bolts 33 should be opened on the angle code stiffener 31 and the secondary steel beam 2, and a plurality of second circular holes for inserting the first bolts 32 should also be opened on the angle code stiffener 31 and the steel pad 32.
