[0028] In related technologies, each node of a prefabricated frame typically includes a precast column and two mutually perpendicular precast beams. To ensure sufficient support for the precast beams, both mutually perpendicular precast beams are usually installed together on the precast column, so that the precast column simultaneously supports both beams. This requires workers to simultaneously adjust and assemble both beams when installing them onto the column, causing inconvenience during construction. To address these issues, this application provides a connecting frame node structure that simplifies the construction of such structures.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] See Figure 1 The connecting frame node structure includes a precast column 1, a first precast beam 2, and a second precast beam 3, wherein the precast column 1 supports the first precast beam 2, and the second precast beam 3 connects two adjacent first precast beams 2 together.

[0031] See Figure 1 and Figure 2 The first precast beam 2 is a precast component, comprising a first beam body 21, a first connector 22, and a first connecting rib 23. The first beam body 21 is made of concrete and is positioned at the top of a precast column 1, which directly supports the first beam body 21. Multiple precast columns 1 can be spaced apart along the length of the first beam body 21. The first beam body 21 is fixedly connected to the top of the precast column 1, specifically, by pouring concrete. The first connector 22 is made of metal, with one end fixedly connected to the first beam body 21, specifically, one end of the first connector 22 can be embedded in the first beam body 21 by pouring concrete. The other end of the first connector 22 is used for a fixed connection to the second precast beam 3. The first connecting rib 23 is also made of metal, with one end fixedly connected to the first connector 22, and the first connecting rib 23 can be fixed to the first connector 22 by welding. The first connecting rib 23 extends from the first connecting member 22 into the first beam 21 and extends along the width direction of the first beam 21.

[0032] See Figure 1-3 The second precast beam 3 is a precast component, comprising a second beam body 31, a second connector 32, and a second connecting bar 33. The second beam body 31 is made of concrete, and its length direction is perpendicular to the length direction of the first beam body 21. The second connector 32 is made of metal, with one end fixedly connected to one end of the second beam body 31. Specifically, one end of the second connector 32 can be embedded in the second beam body 31 by pouring concrete, and the other end is fixedly connected to the first connector 22. The second precast beam 3 also includes multiple second stirrups 34, which are spaced apart within the second beam body 31. The second connecting bars 33 are embedded within the second beam body 31, and the second stirrups 34 are located outside the second connecting bars 33. The second connecting rib 33 extends along the length of the second beam 31. Each end of the second beam 31 is connected to a second connecting member 32. Each end of the second connecting rib 33 is also fixedly connected to a second connecting member 32. The second connecting rib 33 can be fixed to the second connecting member 32 by welding. The second connecting rib 33 corresponds one-to-one with the first connecting rib 23. When the second connecting rib 33 is under stress, it can transmit the stress to the first connecting rib 23 through the first connecting member 22 and the second connecting member 32.

[0033] This application places the first beam 21 on top of the precast column 1, uses the precast column 1 to support the first beam 21, and then fixes the first beam 21 and the second beam 31 together by connecting the first connector 22 and the second connector 32. This eliminates the need to support the second precast beam 3 with the precast column 1 when installing the second precast beam 3, saving the support work for the second precast beam 3, simplifying the installation steps of the prefabricated frame, and making it easier for workers to build the prefabricated frame. Furthermore, the cooperation of the first connecting rib 23 and the second connecting rib 33 ensures that the first precast beam 2 and the second precast beam 3 are subjected to uniform stress, ensuring the prefabricated frame is firmly installed while shortening the construction period.

[0034] See Figure 2 and Figure 3 When the first precast beam 2 is located in the middle of the building, the first precast beam 2 and the second precast beam 3 are combined on a precast column 1 to form a T-shaped or cross-shaped structure. There are multiple first connectors 22, and two adjacent first connectors 22 are located on opposite sides of the width direction of the first beam body 21. In two adjacent first connectors 22, one end of the first connecting rib 23 is fixedly connected to one of the first connectors 22, and the other end of the first connecting rib 23 is fixedly connected to the other first connector 22, so as to ensure that the force can be transmitted between the two adjacent first connectors 22.

[0035] See Figure 2 and Figure 3 In some embodiments, the entire first connecting rib 23 is embedded within the first beam 21. The first connecting rib 23 is elongated and plate-shaped, and is connected to the side of the first connecting member 22 adjacent to another first connecting member 22. The first connecting member 22 includes a first base plate 221, a first connecting plate 222, and an anchor 224. The first base plate 221 is connected to the first beam 21, and the surface of the first base plate 221 is perpendicular to the width direction of the first beam 21. The first base plate 221 can be embedded within the first beam 21 or attached to the outside of the first beam 21. The first base plate 221 is respectively connected to the first connecting plate 224. 2. The first connector 22 is connected to the anchor 224, which is completely embedded in the first beam 21, ensuring that the first connector 22 is firmly fixed to the first beam 21. The surface of the first connecting plate 222 is perpendicular to the surface of the first base plate 221, and the first connecting plate 222 is fixedly connected to the second connector 32. The first connecting rib 23 is connected to the side of the first base plate 221 facing away from the first connecting plate 222. Preferably, the first connecting rib 23 is integrally formed with the first base plate 221. By setting the first connecting rib 23 on the side of the first base plate 221 facing away from the first connecting plate 222, the structure of the first connector 22 can be simplified, thereby saving costs.

[0036] See Figure 4 and Figure 5In some embodiments, the first connecting bar 23 is a steel bar, the first connecting bar 23 is fixedly connected to the top end of the first connecting member 22, the first connecting bar 23 penetrates the first beam 21, and the two ends of the first connecting bar 23 are located outside the first beam 21.

[0037] See Figure 2 and Figure 3 When the first precast beam 2 is located on the side of the building closest to the exterior wall, it combines with the second precast beam 3 on a precast column 1 to form an L-shaped structure. One end of the first connecting rib 23 is connected to the first connecting member 22, while the other end is not connected to the first connecting member 22. The end of the first connecting rib 23 away from the first connecting member 22 is exposed outside the first beam body 21, and this end is bent towards the first beam body 21 and attached to its outer surface. This avoids the first connecting rib 23 occupying external space and ensures a stronger connection between the first connecting rib 23 and the first beam body 21. The end of the first connecting rib 23 away from the first connecting member 22 can be fixed to the first beam body 21 by pouring concrete.

[0038] See Figure 2 and Figure 3 The top of the precast column 1 is provided with a through-hole 11, which is made of metal, preferably a steel bar. The first beam 21 has a through hole, through which the through-hole 11 passes and is fixedly connected to the first beam 21, so that the precast column 1 can be firmly fixed together with the first precast beam 2.

[0039] See Figure 2 and Figure 3 In some embodiments, the first precast beam 2 further includes a corrugated pipe located within a perforation. The corrugated pipe is fixed to the first beam body 21 and is fitted over the through-hole insert 11. The through-hole insert 11 and the corrugated pipe are fixed together by pouring concrete. By placing a corrugated pipe between the through-hole insert 11 and the first beam body 21 and pouring concrete into the perforation, the fixing effect between the through-hole insert 11 and the first beam body 21 can be improved, thereby enhancing the fixing effect between the precast column 1 and the first beam body 21.

[0040] See Figure 4 and Figure 5In some embodiments, the first connector 22 includes a first base plate 221, a first connecting plate 222, a first fixing plate 223, and an anchor 224. The first base plate 221 is connected to the first beam 21, and the surface of the first base plate 221 is perpendicular to the width direction of the first beam 21. The first base plate 221 can be embedded in the first beam 21 or attached to the outside of the first beam 21. The first base plate 221 is connected to the first connecting plate 222, the first fixing plate 223, and the anchor 224 respectively. The anchor 224 is completely embedded in the first beam 21 to ensure that the first connector 22 is firmly fixed to the first beam 21. The surface of the connecting plate 222 is perpendicular to the surface of the first base plate 221. The first connecting plate 222 is fixedly connected to the second connecting member 32. Specifically, the first connecting plate 222 has a first through hole 225, which is fixed to the second connecting member 32 by bolts. The first fixing plate 223 is located at the top or bottom of the first connecting member 22. The surface of the first fixing plate 223 is perpendicular to the surface of the first connecting plate 222 and perpendicular to the surface of the first base plate 221. The first fixing plate 223 is used to weld to the second connecting member 32, thereby improving the fixing effect between the first connecting member 22 and the second connecting member 32. In some embodiments, the first connecting rib 23 is a steel bar. The first connecting rib 23 is welded to the side of the first fixing plate 223 away from the first connecting plate 222, and the first connecting rib 23 is at the same height as the corresponding second connecting rib 33, which facilitates the transmission of force between the first connecting rib 23 and the corresponding second connecting rib 33.

[0041] See Figure 2 and Figure 3 The second connecting member 32 includes a second connecting plate 321 and a second fixing plate 322. One end of the second connecting plate 321 is embedded in the second beam 31, and a second through hole 323 is provided on the other end of the second connecting plate 321. Bolts pass through the second through hole 323 and the first through hole 225, so that the first connecting plate 222 and the second connecting plate 321 are fixed together. The second fixing plate 322 is located at the top or bottom end of the second connecting plate 321. One end of the second connecting rib 33 is welded to the side of the second fixing plate 322 facing away from the second connecting plate 321. The plate surface of the second fixing plate 322 is perpendicular to the plate surface of the second connecting plate 321. The second fixing plate 322 is used to weld with the first fixing plate 223.
