AI Technical Summary
When existing beams and columns are directly connected by bolts, the bolt holes on the surface of the beams and columns are difficult to align during the lifting process, making it difficult to insert the bolts directly, affecting the connection speed of the beams and columns.
A prefabricated steel connecting hybrid frame has been designed, including columns, connecting plates, clamps and beams. The clamps and connecting plates are connected by paired bolts, so that the beams and columns can be moved relatively, so as to facilitate the connection of the other end of the beam to another column.
By connecting the clamp and the connecting plate by pairing bolts, the connection speed between the beam and the column is accelerated. At the same time, the outer locking ring and the inner locking ring limit the rotation of the nut, ensuring the long-term stability of the connection between the beam and the column.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beam-column connection structures, in particular to an edge node structure of an assembled steel-connected hybrid frame. Background Art
[0002] Beams and columns can be divided into rigid connections and hinged connections. Hinged connections are support-type. Generally, the connection between steel structures is rigid. Concrete columns and steel beams are generally hinged. The web and flange plates are welded, which is a rigid connection. This has nothing to do with single plates or double plates. Hinged connections are all connected with mounting bolts.
[0003] The existing beams and columns are directly connected by bolts. However, during the lifting process, the bolt holes on the surfaces of the beams and columns are difficult to align, which makes it difficult to directly insert the bolts, affecting the connection speed of the beams and columns. Therefore, an edge node structure of an assembled steel-connected hybrid frame is proposed to solve the above problem. Utility Model Content
[0004] The utility model provides an edge node structure of an assembled steel-connected hybrid frame, which solves the above technical problems.
[0005] In order to solve the above technical problems, the utility model provides an edge node structure of an assembled steel-connected hybrid frame, including a column, a connecting plate is fixed on the surface of the column, a sliding groove is arranged on the surface of the connecting plate, a splint is sleeved on the surface of the connecting plate, a limiting plate is fixed to the upper end of the splint, a beam is fixed to one end of the limiting plate and the splint, bolt holes are arranged on the surfaces of the connecting plate and the splint, matching bolts are arranged inside the bolt holes on the surface of the splint, and the matching bolts are slidably connected to the sliding groove.
[0006] Preferably, the bolt holes on the surfaces of the connecting plate and the clamping plate are arranged correspondingly, and a guiding slope is provided on the upper end of the connecting plate.
[0007] Preferably, a rotation groove is provided on the surface of the clamping plate, and a connecting ring is rotatably connected inside the rotation groove.
[0008] Preferably, an outer locking ring is fixed to the other end of the connecting ring relative to the clamping plate, and an inner locking ring is clamped at one end of the connecting ring.
[0009] Preferably, one-way teeth are provided on one side opposite to the inner locking ring and the outer locking ring, and the one-way teeth are engaged with each other.
[0010] Preferably, a slot is provided in the middle of the outer locking ring and the inner locking ring, and the slot has an inner diameter equal to that of the bolt hole.
[0011] Compared with the related art, the edge node structure of the assembled steel-connected hybrid frame provided by the utility model has the following beneficial effects:
[0012] The utility model connects the clamping plate and the connecting plate by matching bolts so that the beam and the column can move relatively, so that the other end of the beam can be slightly moved to be connected with another column, thereby accelerating the connection speed of the beam and the column. At the same time, the outer locking ring and the inner locking ring can limit the rotation of the nut, thereby ensuring the long-term stability of the connection between the beam and the column.

[0019] Example, by Figure 1-5 It is given that the utility model includes an edge node structure of an assembled steel-connected hybrid frame, including a column 1, a connecting plate 3 is fixed on the surface of the column 1, a slide groove 5 is arranged on the surface of the connecting plate 3, a splint 7 is sleeved on the surface of the connecting plate 3, a limiting plate 6 is fixed to the upper end of the splint 7, a beam 2 is fixed to one end of the limiting plate 6 and the splint 7, bolt holes 4 are arranged on the surfaces of the connecting plate 3 and the splint 7, matching bolts 8 are arranged inside the bolt holes 4 on the surface of the splint 7, and the matching bolts 8 are slidably connected with the slide groove 5.
[0020] The bolt holes 4 on the surfaces of the connecting plate 3 and the clamping plate 7 are arranged correspondingly, and a guiding inclined surface is arranged on the upper end of the connecting plate 3 .
[0021] A rotation groove 12 is provided on the surface of the clamping plate 7 , and a connecting ring 11 is rotatably connected inside the rotation groove 12 .
[0022] An outer locking ring 9 is fixed to the other end of the connecting ring 11 opposite to the clamping plate 7 , and an inner locking ring 10 is clamped to one end of the outer locking ring 9 located at the connecting ring 11 .
[0023] One-way teeth are provided on one side of the inner locking ring 10 and the outer locking ring 9 opposite to each other, and the one-way teeth are engaged with each other.
[0024] A slot is provided in the middle of the outer locking ring 9 and the inner locking ring 10 , and the slot has an inner diameter equal to that of the bolt hole 4 .
[0025] The beam 2 is lifted by a crane, and the worker holds the beam 2 and aligns the splint 7 with the connecting plate 3 until the limit plate 6 contacts the top of the connecting plate 3, and inserts the matching bolt 8 into the bolt hole 4 on the surface of the splint 7, and the matching bolt 8 is inserted into the slide groove 5 on the surface of the connecting plate 3. At this time, the beam 2 can move relative to the column 1, so as to better connect the other end of the beam 2 with the column 1. After the two ends of the beam 2 are completed, the matching bolt 8 is removed, and the connecting plate 3 and the splint 7 are connected to each other by six bolts. The nut on the surface of the bolt squeezes the outer locking ring 9, and the outer locking ring 9 and the inner locking ring 10 squeeze and fit each other to prevent the nut from loosening.
