Technical Field
[0001] This utility model relates to the field of steel structure beam-column joint assembly technology, specifically a steel structure beam-column connection joint based on finite element analysis. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. With the continuous development of the steel structure housing industry, beam-column joints, as the most basic connection method in steel structures, have also evolved with changes in structural systems and component forms, resulting in various joint structures.
[0003] A search revealed a steel structure workshop beam-column connection node structure proposed in patent publication number CN213626074U, which includes steel structure columns and steel structure beams. The structure includes a fixing sleeve fitted onto the outside of the steel structure column. A structural column groove-shaped reinforcing plate is provided between the inner wall of the fixing sleeve and one side surface of the web of the steel structure column. One end of the steel structure beam passes through the fixing sleeve and is attached to the other side surface of the web of the steel structure column. Upper corner plate fixing members and lower corner plate fixing members are fixedly connected between the two sides of the web of the steel structure beam and the steel structure column, respectively. A structural beam groove-shaped reinforcing plate is provided between the lower end of the lower corner plate fixing member and the fixing sleeve.
[0004] The aforementioned patent literature uses fixed sleeves to reinforce beam-column joints, improving the connection stability. However, in practical use, due to the fixed structure of the beam-column joint, it is necessary to disassemble the joint before splicing when using it with beams of different heights, which is cumbersome and increases the labor intensity of workers. Therefore, there is an urgent need for a steel structure beam-column connection joint based on finite element analysis. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4This utility model provides a technical solution for a steel structure beam-column connection node based on finite element analysis: A steel structure beam-column connection node based on finite element analysis includes a steel structure column 1, a mounting seat 2 slidably installed on the side wall of the steel structure column 1, a steel structure beam 3 detachably installed on the side wall of the mounting seat 2, stress plates 4 fixedly installed on the upper and lower sides of the side wall of the mounting seat 2, an adjustment mechanism 5 provided on the side wall of the stress plates 4, and an ear plate 6 fixedly installed on the inner side wall of the steel structure beam 3, with an installation mechanism 7 provided in the inner cavity of the ear plate 6.
[0024] Furthermore, there are six sets of stress plates 4, which are arranged in an isosceles triangular shape, with the upper and lower stress plates 4 arranged symmetrically.
[0025] Furthermore, the adjustment mechanism 5 includes a transmission worm 51, a handle 52, a transmission worm wheel 53, a rotating seat 54, a transmission screw 55, and a clamping seat 56. A rotating groove 41 is provided between the stress plates 4 on the upper and lower sides. The transmission worm 51 is rotatably installed in the inner cavity of the rotating groove 41. The rotating seat 54 is rotatably installed in the inner cavity of the stress plate 4. The transmission screw 55 is slidably installed in the inner cavity of the rotating seat 54. The clamping seat 56 is threadedly installed on the front and rear ends of the side wall of the transmission screw 55.
[0026] A handle 52 is fixedly installed on the side wall of the transmission worm 51. The transmission worm 51 is meshed with the transmission worm wheel 53. The front and rear sides of the transmission screw 55 have opposite spiral directions. The front and rear side walls of the steel structure column 1 are provided with stepped grooves 11. The clamping seat 56 slides in the inner cavity of the stepped groove 11.
[0027] It should be noted that the mounting base 2 is slidably installed on the side wall of the steel structure column 1. Since the transmission screw 55 is slidably connected to the rotating seat 54, the worker can embed the transmission screw 55 into the rotating seat 54. Then, the worker can rotate the adjusting worm 51 by turning the handle. Since the adjusting worm 51 is meshed with the adjusting worm wheel 53, the adjusting worm wheel 53 can drive the rotating seat 54 to rotate. The transmission screw 55 is slidably installed in the inner cavity of the rotating seat 54. At this time, the rotating seat 54 can drive the transmission screw 55 to rotate. Since the spiral directions of the front and rear sides of the transmission screw 55 are opposite, under the limiting action of the stepped groove 11 on the clamping seat 56, the clamping seats 56 on the front and rear sides can move closer and further away from each other, and engage in the inner cavity of the stepped groove 11 to fix the mounting base 2 and the steel structure column 1.
[0028] Furthermore, the mounting base 2 has a reinforcing groove 21 on its front and rear side walls, and a reinforcing hole 22 is provided in the inner cavity of the reinforcing groove 21.

Four sets of positioning grooves 72 are arranged in a ring at equal intervals around the center of the right side wall of the mounting base 2. The positioning nut 71 is threaded through the ear plate 6 and installed in the inner cavity of the positioning groove 72.
[0031] Working principle:
[0032] After the worker installs the steel structure column 1, the mounting base 2 can be slidably installed on the side wall of the steel structure column 1. Since the transmission screw 55 is slidably connected to the rotating seat 54, the worker can embed the transmission screw 55 into the rotating seat 54. Then, the worker rotates the handle to make the adjusting worm 51 rotate. Since the adjusting worm 51 is meshed with the adjusting worm wheel 53, the adjusting worm wheel 53 can drive the rotating seat 54 to rotate. The transmission screw 55 is slidably installed in the inner cavity of the rotating seat 54. At this time, the rotating seat 54 can drive the transmission screw 55 to rotate. Since the spiral directions of the front and rear sides of the transmission screw 55 are opposite, under the limiting action of the stepped groove 11 on the clamping seat 56, the clamping seats 56 on the front and rear sides can move closer and further away from each other, and engage in the inner cavity of the stepped groove 11 to fix the mounting base 2 and the steel structure column 1.
[0033] Afterwards, workers can further fix the mounting base 2 by setting the reinforcing groove 21 and the reinforcing hole 22. The stress plate 4 is set in an isosceles triangular shape, which can further improve the stable support performance of the entire device.
[0034] After the mounting base 2 is installed, the steel structure beam 3 can be installed horizontally and vertically by setting multiple sets of positioning slots 72, which greatly improves the convenience of the whole device.
[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
