[0002] In today's construction industry, which is constantly pursuing efficiency and quality, prefabricated buildings are gradually becoming a development trend in the construction field due to their advantages such as speed and low environmental pollution. However, traditional prefabricated buildings still have many problems at the beam-column connection nodes. For example, in the current prefabricated building structure, welding is often used when installing T-beams during the beam-column assembly process, which is difficult, time-consuming and labor-intensive. In addition, in the connection construction method between T-beams and box columns, the connection method of ordinary connecting plates and bolts is often difficult to balance the connection firmness and error adjustment. Dimensional deviations are prone to occur during construction and cannot be flexibly adjusted, which will affect the overall safety of the building.

[0003] Therefore, there is an urgent need at present for a beam-column connection structure that facilitates rapid assembly of prefabricated buildings. This structure can be flexibly adjusted according to construction needs and can compensate for construction errors, while achieving precise positioning and rapid assembly of building beams and columns (T-beams and box columns), and the connection is firm and has good stability. Summary of the Invention

[0004] To address the problems of existing technologies in the construction of T-beam and box column connection structures, such as high construction difficulty, easy dimensional deviations, and inflexible adjustments that affect the overall safety of the building, this utility model provides a beam-column connection structure that facilitates rapid assembly of prefabricated buildings to solve these problems.

[0005] To achieve the above objectives, this utility model provides a beam-column connection structure that facilitates rapid assembly of prefabricated buildings. The structure includes a connection assembly comprising a top plate, side plates fixedly disposed at the bottom of the four sides of the top plate, and pads located between the side plates and the box column. The number of pads is determined according to the gap between the side plates and the box column. Bolts pass through the side plates and pads and are threadedly connected to the box column, thus achieving a fixed connection between the connection assembly and the upper end of the box column. A placement assembly fixedly disposed on top of the connection assembly includes a bearing base plate and four sets of connecting blocks arranged in an array on top of the bearing base plate. A placement groove is provided between adjacent connecting blocks to limit the placement of the horseshoe portion of the T-shaped beam. A clamping assembly fixedly disposed on top of the connection assembly includes a clamping frame with a cross-shaped structure and clamping grooves at the ends of the clamping frame. Bolts pass sequentially through the clamping grooves and the web of the T-shaped beam to clamp and fix the T-shaped beam.

[0006] Furthermore, the T-beam has a stepped horseshoe-shaped portion, web, and wing plate at its connecting end; the horseshoe-shaped portion is provided with a positioning hole located in front of the web, which is used for quick positioning and installation of the connecting end of the T-beam; the web is provided with multiple sets of first clamping holes.

[0007] Furthermore, the clamping assembly also includes a positioning base plate, a rib plate, an inclined plate, and a first positioning post.

[0009] Furthermore, the placement assembly also includes a second positioning post, which is located in the placement groove and its position corresponds to the positioning hole provided on the horseshoe. Its length is less than the length of the positioning hole. By inserting the second positioning post into the positioning hole, the longitudinal installation and positioning of the horseshoe can be quickly completed.

[0010] Furthermore, the top plate is a square steel plate with multiple sets of connecting bolt seats on its outer periphery. Bolts pass through the connecting bolt seats and are threadedly connected to the bearing base plate, thereby achieving a fixed connection between the placement component and the connecting component.

[0012] Furthermore, the upper connecting plate is also provided with a plurality of fifth bolt holes, the positions of which correspond to the connecting bolt seats respectively. By inverting the connecting assembly to the top of the upper connecting plate, the fifth bolt holes are aligned with the connecting bolt seats.

The bolts in the three bolt holes 421 and the second bolt hole 321 are tightened with nuts to fix the clamping assembly 3 to the top of the placement assembly 4, thereby completing the horizontal limiting and fixing of the T-beam 1. The web plate 12 is clamped and fixed by the bolts passing through the second clamping hole 331 and the first clamping hole 121 in sequence and then connecting with the nuts, thereby completing the vertical limiting and fixing of the T-beam 1.
