A second cylindrical hole 416 and a sliding hole 417 are provided on the inner walls of the two grooves of the steel column 1, and each second cylindrical hole 416 is respectively connected to the inside of each sliding hole 417. A T-shaped rod 411 is fixed between the inside of each first cylindrical hole 415 and the inside of each second cylindrical hole 416. The outer surface of each T-shaped rod 411 is movably sleeved with a second spring 412, the other side of the two clamping plates 408 is provided with a placement groove 413, the end faces of the two T-shaped rods 411 are fixed with a clamping strip 414, the top end of each limiting rod 405 is respectively located inside each limiting groove 403, the bottom end of each first spring 406 is respectively fixed to the upper side of each limiting rod 405, the top end of each first spring 406 is respectively fixed to the bottom of the support plate 401, each rectangular block 410 is respectively located inside each perforated block 407, one end of the two second springs 412 is respectively fixed to the surface of the two T-shaped rods 411, and the other end of the two second springs 412 is respectively fixed to the two clamping plates One side of the steel beam 2 is fixed with each other, the size of each of the clips 414 is respectively matched with the size of each placement slot 413 and the size of each slide hole 417, the top of the support plate 401 is in contact with the bottom of the steel beam 2, one side of the support plate 401 is in contact with the surface of the steel column 1, one side of the two reinforcement blocks 402 is in contact with the surface of the steel column 1, and a plurality of the limit grooves 403 are all opened at the bottom of the steel beam 2, the two clips 408 are respectively located in the two grooves of the steel column 1, and the other sides of the two clips 408 are respectively in contact with the inner walls of the two grooves of the steel column 1, one end of the two perforated blocks 407 are both movable through the surface of the steel column 1, and one end of the two perforated blocks 407 respectively extends to the two grooves of the steel column 1,One side of the two clips 414 is in contact with the surface of the steel column 1.

[0041] In this embodiment, when it is necessary to strengthen the stability between the steel beam 2 and the steel column 1 fixed together, the support plate 401 is picked up, and then all the limit rods 405 are moved at the same time. At this time, each limit rod 405 moved will cooperate with the support plate 401 to stretch the first spring 406 connected thereto. When the top end surface of each limit rod 405 is at the same horizontal plane with the top of the support plate 401, the support plate 401 is moved. At this time, the moving support plate 401 will drive the two reinforcement blocks 402, the reinforcement rod 404, the multiple limit rods 405, the multiple first springs 406 and the two perforated blocks 407 to move at the same time. When the same end of the two perforated blocks 407 passes through the steel column 1 , and extend to the two grooves of the steel column 1 respectively, and continue to move until one side of the support plate 401 contacts the surface of the steel column 1.

[0042] Embodiment 2: According to Figure 1-Figure 8 , Fig.11 , Fig.12 and Fig.14 As shown, the node connection mechanism 3 includes a rectangular plate 301, two groups of clamping rods 306 and a group of short rods 307, two clamping blocks 309 are arranged between each of the short rods 307 and each group of clamping rods 306, and each of the clamping rods 306 and each short rod 307 are preset with clamping holes 308 of varying numbers, and each of the clamping rods 306 and the short rods 307 can be plugged into a corresponding clamping block 309 through the two clamping holes 308, and each of the clamping blocks 309 is provided with a U-shaped groove 312, and each of the U-shaped grooves 312 is provided with a U-shaped pad 313, and a limiting block 314 is inserted between every two of the U-shaped grooves 312, and the other side of the rectangular plate 301 is in contact with one side of the steel beam 2, and two symmetrical connecting plates 302 are fixed to the other side of the rectangular plate 301, and the two connecting plates 302 are respectively located in the two grooves of the steel beam 2, and two inclined plates are fixed to the opposite sides of the two connecting plates 302 303, one side of the four inclined plates 303 is fixed to the other side of the rectangular plate 301, one side of the rectangular plate 301 is provided with four first circular holes 304, and the opposite sides of the two connecting plates 302 are provided with two second circular holes 305, the clamping ends of the two groups of clamping rods 306 are respectively movably penetrated through the two groove inner walls of the steel column 1, and the four second circular holes 305 are divided into two groups, each of the short rods 307 is respectively movably sleeved between the inside of each group of second circular holes 305, each of the clamping rods 306 is respectively located inside each first circular hole 304, and the same end of the two short rods 307 is movably penetrated through one of the groove inner walls of the steel beam 2, and the opposite sides of the two connecting plates 302 are provided with cylindrical grooves 310, and a spring body 311 is arranged inside each cylindrical groove 310, and the opposite ends of the two spring bodies 311 are respectively fixed to the inside of the two cylindrical grooves 310.

[0043] In this embodiment, when the steel column 1 and the steel beam 2 need to be quickly installed together, the steel column 1 is first erected on the ground by a crane and fixed to the ground, and then the steel beam 2 is driven to move by the crane (the moving steel beam 2 will drive the spring body 311, the U-shaped pad 313 and the limit block 314 installed thereon to move at the same time). When the moving steel beam 2 is about to approach the steel column 1, the movement of the steel beam 2 is stopped first, and then the staff is asked to use the lifting platform to raise it to a suitable position (the staff can install the node connection mechanism 3 by hand), and then the two connecting plates 302 and the two sets of inclined plates 303 are moved to the upper and lower surfaces of the steel beam 2 respectively by using the rectangular plate 301. The two grooves are then moved together with the rectangular plate 301, the two connecting plates 302, the two spring bodies 311, the two groups of U-shaped pads 313, the two limit blocks 314 and the steel beam 2. When one side of the rectangular plate 301 contacts the surface of the steel column 1, the movement of the steel beam 2 is stopped, and then the position of the steel beam 2 is fine-tuned. When the position of the steel beam 2 is adjusted, the four clamping rods 306 are installed on the steel column 1 in turn. When the four clamping rods 306 are installed, the clamping end of each clamping rod 306 just passes through the inside of the corresponding first circular hole 304, and then the short rod 307 is installed between the inside of each group of second circular holes 305. That is, the two short rods 307 and the two groups of second circular holes 305 are matched to connect the two connecting plates 302 and the steel beam 2 together, and then the position and angle of the clamping holes 308 on each clamping rod 306 and each short rod 307 are adjusted, and then one of the limit blocks 314 is moved first. At this time, the moving limit block 314 will allow the spring body 311 connected thereto to be stretched out from the inside of the corresponding cylindrical groove 310, and at the same time, it will also drive a group of U-shaped pads 313 connected thereto to move. When the limit block 314 moves to a suitable position, the movement of the limit block 314 is stopped, and then the clamping blocks 309 are installed between the two corresponding groups of clamping holes 308. When the two clamping blocks 314 are moved to a suitable position, the movement of the limit block 314 is stopped, and then the clamping blocks 309 are installed between the two corresponding groups of clamping holes 308. When all of 09 are installed, release the force applied by the corresponding limit block 314. At this time, the limit block 314 will automatically return to the initial position under the cooperation of the rebound force of the spring body 311 and the corresponding two U-shaped grooves 312. When the limit block 314 returns to the initial position, the corresponding two clamping blocks 309 will not be able to automatically move out from the inside of the corresponding group of clamping holes 308. Then repeat the above steps, and install the other two clamping blocks 309 in the inside of the corresponding group of clamping holes 308, and they cannot automatically move out from the inside of the corresponding group of clamping holes 308. When the node connection mechanism 3 is installed, the steel beam 2 and the steel column 1 can be fixed together.

[0044] The effect and working principle of the entire mechanism are as follows:

[0045] When the steel column 1 and the steel beam 2 need to be quickly installed together, the steel column 1 is first placed on the ground using a crane and fixed to the ground, and then the steel beam 2 is driven to move by the crane (the moving steel beam 2 will drive the spring body 311, U-shaped pad 313 and limit block 314 installed thereon to move at the same time). When the moving steel beam 2 is about to approach the steel column 1, the movement of the steel beam 2 is stopped first, and then the staff is asked to use the lifting platform to raise it to a suitable position (the staff can install the node connection mechanism 3 by hand), and then the two connecting plates 302 and the two groups of inclined plates 303 are moved to the two grooves on the steel beam 2 by using the rectangular plate 301, and then the rectangular plate 301, the two connecting plates 302, the two spring bodies 311, the two groups of U-shaped pads 313, the two limit blocks 314 and the steel beam 2 are moved together. When one side of the rectangular plate 301 contacts the surface of the steel column 1, the movement of the steel beam 2 is stopped, and then the position of the steel beam 2 is fine-tuned.

[0046] When the position of the steel beam 2 is adjusted, the four clamping rods 306 are installed on the steel column 1 in turn. When the four clamping rods 306 are installed, the clamping end of each clamping rod 306 just passes through the inside of the corresponding first circular hole 304, and then the short rod 307 is installed between the inside of each group of second circular holes 305, that is, the two short rods 307 and the two groups of second circular holes 305 cooperate to connect the two connecting plates 302 and the steel beam 2 together, and then adjust the position and angle of the clamping hole 308 on each clamping rod 306 and each short rod 307, and then move one of the limit blocks 314 first. At this time, the moved limit block 314 will allow the spring body 311 connected to it to be stretched out from the inside of the corresponding cylindrical groove 310, and at the same time, it will also drive a group of U-shaped pads 313 connected to it to move. When the limit block 31 When the stop block 314 moves to the appropriate position, the movement of the limit block 314 is stopped, and then the block 309 is installed between the two corresponding groups of the card holes 308. When the two card blocks 309 are installed, the force applied by the corresponding limit block 314 is released. At this time, the limit block 314 will automatically return to the initial position under the cooperation of the rebound force of the spring body 311 and the corresponding two U-shaped grooves 312. When the limit block 314 returns to the initial position, the corresponding two card blocks 309 will not be able to automatically move out from the inside of the corresponding group of card holes 308. Then repeat the above steps, and install the other two card blocks 309 in the inside of the corresponding group of card holes 308, and they cannot be automatically moved out from the inside of the corresponding group of card holes 308. When the node connection mechanism 3 is installed, the steel beam 2 and the steel column 1 can be fixed together.

[0047] When it is necessary to strengthen the stability between the steel beam 2 and the steel column 1 fixed together, the support plate 401 is picked up, and then all the limit rods 405 are moved at the same time. At this time, each limit rod 405 moved will make the first spring 406 connected thereto be stretched with the cooperation of the support plate 401. When the top end surface of each limit rod 405 is at the same horizontal plane as the top of the support plate 401, the support plate 401 is moved. At this time, the moving support plate 401 will drive the two reinforcement blocks 402, the reinforcement rods 404, and multiple The limiting rod 405, the plurality of first springs 406 and the two perforated blocks 407 move simultaneously. When the same end of the two perforated blocks 407 passes through the surface of the steel column 1 and respectively extends into the two grooves of the steel column 1, the limiting rod 405 continues to move until one side of the support plate 401 contacts the surface of the steel column 1. When one side of the support plate 401 contacts the surface of the steel column 1, the force applied to all the limiting rods 405 is released. At this time, each limiting rod 405 will be reset to its original position with the cooperation of the corresponding first spring 406.

[0048] When the limit rod 405 returns to its original position, the top of each limit rod 405 is clamped in the corresponding limit slot 403, and then one of the clamping plates 408 is picked up, and then the T-shaped rod 411 on it is rotated 90 degrees, and then the T-shaped rod 411 is moved again until the clamping strip 414 on the T-shaped rod 411 moves into the corresponding placement slot 413, and then one of the clamping plates 408 is moved again, and the moved clamping plate 408 will drive the second spring 412, the rectangular block 410 and the clamping strip 414 connected thereto to move simultaneously. When the surface of the card plate 408 contacts the inner wall of one of the grooves of the steel column 1, and one end of the corresponding perforated block 407 is inside the rectangular hole 409 on the card plate 408, the card plate 408 is moved downward. When the card plate 408 completes the downward movement operation, the rectangular block 410 moves to the inside of the perforated block 407, and at the same time, the inside of the first cylindrical hole 415 on the card plate 408 is just connected with the inside of the corresponding second cylindrical hole 416. At this time, the tension of the corresponding T-shaped rod 411 is loosened, so that the T-shaped rod 411 drives the card strip 414 to reset;

[0049] When the clip 414 passes through the corresponding sliding hole 417 and the end of the T-shaped rod 411 close to the clip 414 moves to the corresponding second cylindrical hole 416, the torsion force applied to the T-shaped rod 411 is released. At this time, the T-shaped rod 411 will drive the clip 414 to rotate and return to the initial state with the cooperation of the second spring 412, thereby achieving the fixation of the clip plate 408. Then repeat the above-mentioned operation steps to install the other clip plate 408. When the two clip plates 408 are installed, the support plate 401 can complete the fixing operation. At this time, under the action of the reinforcing mechanism 4, the stability of the steel column 1 and the steel beam 2 after connection can be enhanced. When the steel beam 2 and the steel column 1 need to be separated, at this time, you only need to reverse the operation to remove the reinforcing mechanism 4, and then reverse the operation to remove the node connection mechanism 3.

[0050] Among them, the steel beam 2 and the steel column 1 both have two grooves, and the cross-sectional shapes of the steel beam 2 and the steel column 1 are both H-shaped.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
