[0004] In view of the deficiencies existing in the prior art, the steel structure connecting structure based on BIM is provided, which can stably connect the I-beam to the extension pile.

[0005] To achieve the above purpose, the following technical scheme is provided: the steel structure connecting structure based on BIM, comprising a connecting pile, an extension pile, a stabilizing assembly, a first connecting assembly, a second connecting assembly and a third connecting assembly, the extension pile is fixedly connected to the connecting pile, the extension pile is used for splicing a group of I-beams, and the group of I-beams is formed into a "II" shaped structure by splicing two I-beams, the stabilizing assembly is used for connecting two adjacent groups of I-beams, the first connecting assembly and the second connecting assembly are used for respectively penetrating through two I-beams of the same group and the corresponding stabilizing assembly, and are both connected to the extension pile, and the third connecting assembly is connected with the first connecting assembly and the second connecting assembly.

[0006] In summary, the technical scheme has the following beneficial effects: in the steel structure connection, due to the existence of material nonlinearity, geometric nonlinearity and contact nonlinearity and other factors, the stress calculation is more difficult, the material nonlinearity is mainly reflected in the stress-strain relationship of the steel, with the increase of the stress, the strain of the steel no longer maintains the linear relationship, which increases the difficulty of stress calculation, the geometric nonlinearity is mainly reflected in the large deformation of the connecting structure, when the connecting structure is subjected to a larger load, the geometric shape may change, thereby affecting the distribution and size of the stress, the contact nonlinearity is mainly reflected in the contact surface between the connecting pieces, due to the existence of friction, slip and other phenomena of the contact surface, the stress calculation is more complex, BIM is a building information model or building information management, which takes various related information data of a building engineering project as the basis to establish a three-dimensional building model, and simulates the real information of the building through digital information simulation, through the BIM technology, the steel structure connection can be simulated before construction, and the possible problems and challenges in the construction process can be predicted, which helps construction personnel to develop countermeasures in advance, reduces the uncertainty and risk in the construction process, in the application scenario of the utility model, BIM technology is needed to assist in calculation and design;

[0007] In the prior art, two I-beams are usually directly welded or connected on the extension pile by bolts, when the two I-beams are stressed, they will move obliquely to the two sides, which is the driving force of the separation of the centers above the two I-beams, and the two ends will press the extension pile downward, at the same time, the centers below the two I-beams will also press the center of the extension pile upward, so the extension pile is likely to be split into two halves under the action of the two I-beams.

[0008] In the utility model, in addition to the first connecting assembly and the second connecting assembly being connected to the extension pile, a third connecting assembly is arranged for connecting the first connecting assembly and the second connecting assembly, in this case, the force of the oblique movement to the two sides generated by the two I-beams when stressed will be dispersed at the connecting positions of the two ends of the third connecting assembly, and the upward pressing force of the centers below the two I-beams to the center of the extension pile will be borne by the third connecting assembly itself, so the bearing force of the extension pile is mostly transferred to the first connecting assembly, the second connecting assembly and the third connecting assembly, the first connecting assembly and the second connecting assembly directly connect the two I-beams to the extension pile, thereby realizing the purpose of stably connecting the I-beams on the extension pile, and further preventing the extension pile from being broken through the third connecting assembly, and strengthening the connection between the two groups of I-beams through the stabilizing assembly, thereby further strengthening the connection stability of the I-beams.

[0009] In the utility model, two I-shaped steels are directly connected to the extension pile through the first connecting assembly and the second connecting assembly, so that the purpose that the I-shaped steel is stably connected on the extension pile is realized, then the third connecting assembly is used for preventing the extension pile from being broken, and the connection between the two groups of I-shaped steels is strengthened through the stabilizing assembly, so that the connection stability of the I-shaped steel is further strengthened.
