[0021] As Figures 1 to 4 shown, a steel structure joint reinforcing device, including first profiled piece 1, the left end of first profiled piece 1 is fixedly connected with second profiled piece 2, the right end of first profiled piece 1 is fixedly connected with third profiled piece 3, the inner side of second profiled piece 2 is slidably connected with first square box 4 and second square box 5, the inner side of first profiled piece 1 is slidably connected with third square box 6, the outer surface of first square box 4 and second square box 5 is fixedly connected with connecting piece 7 respectively, two connecting pieces 7 are fixedly connected on the outer surface of third square box 6, the inside of third square box 6 is provided with fixing mechanism 8.
[0022] Fixing mechanism 8 includes first fixed sliding block 804 and second fixed sliding block 806, first fixed sliding block 804 and second fixed sliding block 806 are slidably connected in the inside of third square box 6, V-shaped block 802 is slidably connected between first fixed sliding block 804 and second fixed sliding block 806.
[0023] The upper surface of the V-shaped block 802 is rotationally connected with a screw 801, the screw 801 is internally threadedly connected with the third-party box 6 and extends to the outside of the third-party box 6, and the screw 801 is externally threadedly connected with a nut 803.
[0024] The second fixed sliding block 806 is fixedly connected with a strip plate 808, and the strip plate 808 is fixedly connected with two cylinders 809 and two springs 811 away from the V-shaped block 802.
[0025] The inside of each cylinder 809 is slidably connected with a nail-shaped sliding rod 810, and the end, away from the strip plate 808, of each nail-shaped sliding rod 810 is fixedly connected to the inner wall of the third-party box 6.
[0026] The side, away from the V-shaped block 802, of the first fixed sliding block 804 is fixedly connected with a first anti-skid plate 805, and the side, away from the V-shaped block 802, of the second fixed sliding block 806 is fixedly connected with a second anti-skid plate 807.
[0027] As shown in Figures 1 to 4 some actual applications, the fixing mechanism 8 is provided with three parts, one part is arranged in the first-party box 4, one part is arranged in the second-party box 5, and one part is arranged in the third-party box 6, the strip plate 808, the cylinder 809, the nail-shaped sliding rod 810 and the spring 811 in each fixing mechanism 8 are provided with two groups, one group is arranged on the second fixed sliding block 806, and the other group is arranged on the first fixed sliding block 804, and the two groups are in a symmetrical state.
[0028] As shown in Figures 1 to 4 some actual applications, the first workpiece 1 and the second workpiece 2 are connected by welding, and slight loosening and a decrease in bearing capacity occur at the connection due to long-term use and external environmental influence. In order to enhance the stability and bearing capacity of the node, the reinforcing device is adopted. In the reinforcing process, the first-party box 4 and the second-party box 5 are slidably installed to the left inner side and the right inner side of the second workpiece 2 respectively. At the same time, the third-party box 6 is also slidably installed to the inner side of the first workpiece 1. Subsequently, the screw 801 is rotated to drive the V-shaped block 802 to slide in the third-party box 6, and then the first fixed sliding block 804 and the second fixed sliding block 806 are pushed to tightly adhere to the inner walls of the second workpiece 2 and the first workpiece 1 respectively. In this process, the first anti-skid plate 805 and the second anti-skid plate 807 effectively increase the friction between the sliding blocks and the inner walls of the workpieces, preventing the sliding of the reinforcing device. After the reinforcing is completed, a bearing capacity test is carried out, and the result shows that the bearing capacity of the reinforced node is obviously improved, and the stability is significantly improved. When it is necessary to remove the reinforcing device, the screw 801 is only needed to be reversely rotated, so that the reinforcing device can be conveniently removed from the workpiece without causing damage to the original structure.
[0029] As Figures 1 to 4 shown in some practical applications, due to long-term bearing heavy load and external environment corrosion, some large factory building steel structure due to the long-term bearing heavy load and external environment corrosion, part of the connection node appears serious bearing capacity decline and loose phenomenon. In order to guarantee the safe use of the plant, it is urgent to reinforce these nodes. In this reinforcement, the steel structure node reinforcing device is adopted. Through careful design and installation, the reinforcing device successfully improves the bearing capacity and stability of the node. Especially in the design of the fixing mechanism 8, by reasonably setting the strip plate 808, the cylinder 809, the nail type slide rod 810 and the spring 811 and other components, the quick installation and disassembly of the reinforcing device are realized, and the reinforcing efficiency is greatly improved. After the reinforcement is completed, the reinforced node is comprehensively detected and evaluated. The results show that the reinforced node not only has a significant improvement in bearing capacity, but also has good stability and durability in use. This embodiment fully proves the effectiveness and reliability of the steel structure node reinforcing device in practical engineering application.
[0030] Working principle: when the first workpiece 1 and the second workpiece 2 need to be reinforced, first, the fixing mechanism 8 in the first square box 4, the second square box 5 and the third square box 6 is adjusted to the initial state, then the first square box 4 and the second square box 5 are respectively slid to the left inner side and the right inner side of the second workpiece 2, and the third square box 6 is also slid to the inner side of the first workpiece 1, until the first square box 4, the second square box 5 and the third square box 6 are in the appropriate position. Then, the fixing of the reinforcing device is realized by operating the fixing mechanism 8. Specifically, the screw 801 is rotated, since the screw 801 is in threaded connection with the inside of the third square box 6, the rotation of the screw 801 will drive the V-shaped block 802 to slide along the inside of the third square box 6, and at the same time, the first fixed sliding block 804 and the second fixed sliding block 806 are pushed to move in opposite directions. During this process, the first fixed sliding block 804 and the second fixed sliding block 806 will be tightly attached to the inner walls of the second workpiece 2 and the first workpiece 1 respectively, so as to realize the close fixing between the reinforcing device and the workpiece. During the fixing process, the first anti-skid plate 805 and the second anti-skid plate 807 are respectively arranged on the outer surfaces of the first fixed sliding block 804 and the second fixed sliding block 806, for increasing the friction and preventing the reinforcing device from sliding under stress. Finally, when the reinforcing device needs to be removed, the screw 801 is only needed to be rotated in the reverse direction, so that the V-shaped block 802 moves in the opposite direction, and the first fixed sliding block 804 and the second fixed sliding block 806 are released from the tightly attached state to the inner walls of the workpiece, so that the reinforcing device can be conveniently removed from the workpiece. At the same time, by arranging the strip plate 808, the cylinder 809, the nail-shaped sliding rod 810 and the spring 811, when the screw 801 is rotated in the reverse direction, the screw 801 drives the V-shaped block 802 to move upwards, so as to drive the first fixed sliding block 804 and the second fixed sliding block 806 to be automatically recovered into the inside of the third square box 6 through the rebound force of the spring 811, facilitating the next reinforcing operation.
