[0002] Precast foundation beams are concrete beams prefabricated in factories, usually used to bear the load of the superstructure and provide lateral support. Precast foundations refer to precast foundation components, such as foundation plates and foundation piles, which are used to support the overall structure of the building. Connection nodes are the parts that connect precast foundation beams and precast foundations. Their design needs to consider factors such as load transfer, seismic performance, and construction convenience. The connection nodes between precast foundation beams and precast foundations are an important part of construction projects for connecting precast components.

[0003] When the current prefabricated foundation beam and prefabricated foundation connection node is in use, the prefabricated foundation beam is generally connected to the prefabricated foundation by pouring connection or using heavy steel bolts. The connection steps of the two are relatively cumbersome, which not only increases the difficulty of connecting the prefabricated foundation beam and the prefabricated foundation, but also delays the connection period of the prefabricated foundation beam and the prefabricated foundation, resulting in poor use effect.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figures 1 to 10 In an embodiment of the present invention, a prefabricated foundation beam and a prefabricated foundation connection node is arranged between the foundation beam 1 and the foundation column 2, and includes a mosaic portion 101 and a snap-fit ​​portion 201, wherein the mosaic portion 101 is integrally cast with the foundation beam 1, and the snap-fit ​​portion 201 is integrally cast with the foundation column 2.

[0036] The locking portion 201 is formed with a fitting recess 2011 that matches the fitting portion 101 . The surrounding surfaces of the fitting recess 2011 are a first straight surface, a first inclined surface, a second inclined surface, and a third inclined surface. The first straight surface coincides with one surface of the base column 2 .

[0037] The surrounding surfaces of the engaging portion 101 sequentially form a second straight surface, a fourth inclined surface, a fifth inclined surface and a sixth inclined surface corresponding to the surrounding surfaces of the engaging recess 2011 ; the second straight surface coincides with one surface of the foundation beam 1 .

[0038] In this embodiment, when the foundation beam 1 is connected to the foundation column 2, the embedding portion 101 is aligned with the locking portion 201. Under the action of gravity of the foundation beam 1, the embedding portion 101 will be embedded in the embedding recess 2011. The second straight surface, fourth inclined surface, fifth inclined surface and sixth inclined surface provided on the embedding portion 101 are fitted with the first straight surface, first inclined surface, second inclined surface and third inclined surface provided around the embedding recess 2011, so that the connection of the foundation beam 1 on the foundation column 2 can be limited. Because the foundation beam 1 is pressed downward by gravity, the embedding portion 101 will be more tightly contacted in the locking portion 201. Through the design of multiple inclined surfaces, the connection position of the foundation beam 1 on the foundation column 2 can be limited, so that the connection between the foundation beam 1 and the foundation column 2 cannot be displaced left and right, front and back, thereby improving the connection firmness between the two and improving the convenience of connection between the foundation beam 1 and the foundation column 2.

[0039] As a further solution of the present invention, a slider 3 is further provided on the foundation beam 1 , and a docking port 204 adapted to the slider 3 is opened on the surface of the foundation column 2 where the engaging portion 201 is provided.

[0040] After the engaging portion 101 is completely embedded in the engaging recess 2011 , the slider 3 is completely aligned with the docking port 204 and can be slidably embedded in a portion of the docking port 204 .

[0041] In this embodiment, after the engaging portion 101 and the engaging recess 2011 are fully engaged, one end of the slider 3 is aligned with the docking port 204, and the slider 3 can be moved toward one end of the docking port 204, so that the slider 3 slides and is embedded in a part of the docking port 204, thereby making the slider 3 act between the connection between the foundation beam 1 and the foundation column 2, and the connection part of the foundation beam 1 on the foundation column 2 will not move up and down, thereby improving the stability of the connection between the two.

[0042] As a further solution of the present invention, the slider 3 is arranged in a convex shape, and the slider 3 is slidably arranged in a sliding groove 103 opened on the foundation beam 1 and correspondingly adapted to the slider 3.

[0043] The docking port 204 is adapted to the shape of the slider 3 .

[0044] Extension portions are formed on both sides of the slider 3 .

[0045] In this embodiment, the slider 3 slides in the slide groove 103 opened on the foundation beam 1. When the foundation beam 1 is hoisted and prepared for installation, the slider 3 is located in the slide groove 103 on the side away from the end of the foundation beam 1. After the foundation beam 1 is installed and engaged, the slider 3 is adjusted to slide inside the slide groove 103 so that the slider 3 is docked in the docking port 204, which can realize the upper and lower position limiting, avoid displacement at the connection, and improve the convenience of connection.

[0046] As a further solution of the present invention, four first steel bars 102 are arranged in a rectangular distribution on the foundation beam 1 , and two first steel bars 102 on the side of the foundation beam 1 away from the fitting portion 101 correspond to the extensions on both sides of the slider 3 .

[0047] The foundation column 2 is formed with a movable cavity 203 capable of accommodating the first steel bar 102 , and the movable cavity 203 is arranged along the height direction of the foundation column 2 .

[0048] In this embodiment, when the foundation beam 1 is hoisted and connected to the foundation column 2, the first steel bar 102 is first inserted into the movable cavity 203. When the foundation beam 1 falls due to gravity, the first steel bar 102 will slide in the movable cavity 203. After the foundation beam 1 and the foundation column 2 are connected, concrete can be used to seal the movable cavity 203 in the later stage, so that the first steel bar 102 is fixed in the movable cavity 203 to improve the connection firmness. Alternatively, the movable cavity 203 can be sealed without being blocked, and the upper and lower limit positions of the slider 3 after docking can also achieve a firm connection between the foundation beam 1 and the foundation column 2.

[0049] As a further solution of the present invention, a base 205 is integrally cast at the bottom of the foundation column 2 , and six second steel bars 202 are further provided in the foundation column 2 .

[0050] In this embodiment, the base 205 is located on the ground. The base 205 can increase the force-supporting area of ​​the foundation column 2, improve the construction stability of the building, and prevent the foundation column 2 from collapsing and falling due to the small force-supporting area of ​​the ground when it is located on the ground, thereby improving the overall support stability.

[0051] As a further solution of the present invention, the six second steel bars 202 are symmetrically arranged in two rows, and the six second steel bars 202 are staggered with the movable cavity 203 opened on the foundation column 2, and the edges of the three second steel bars 202 close to the docking port 204 are tangent to the docking port 204.

[0052] In this embodiment, the second steel bar 202 and the docking port 204 and the movable cavity 203 are all staggered, which can prevent the second steel bar 202 from affecting the opening of the movable cavity 203 and the docking port 204 on the foundation column 2, and can improve the overall strength of the foundation column 2, avoiding the problem that the overall strength of the foundation column 2 is affected due to disconnection or lack of connection of the second steel bar 202 inside the foundation column 2.

[0053] As a further solution of the present invention, a protrusion 301 is integrally formed on the upper portion of the sliding block 3 , and the height of the protrusion 301 is higher than one side of the foundation beam 1 .

[0054] In this embodiment, the protrusion 301 on the slider 3 is higher than one side of the foundation beam 1. After the foundation beam 1 is hoisted, the protrusion 301 can be knocked with a hammer or other tools to make the slider 3 slide on the foundation beam 1, so that the slider 3 can be successfully docked with the docking port 204, and the connection between the foundation beam 1 and the foundation column 2 is limited in the upper and lower directions to avoid displacement, thereby improving the sliding convenience of the slider 3.

[0055] As a further solution of the present invention, the slider 3 is symmetrically provided with bolt holes away from the end connected to the docking port 204, and when one side of the slider 3 is inserted into the docking port 204, the bolt hole is provided with a positioning hole 104 at the corresponding position on the slide groove 103.

[0056] When the bolt hole is aligned with the positioning hole 104 , the bolt 302 is inserted between the two, and a nut is threadedly connected to one end of the bottom of the bolt 302 .

[0057] In this embodiment, after a part of one end of the slider 3 is inserted into the docking interface 204, the positioning hole 104 is aligned with the threaded hole opened on the slider 3. By inserting the bolt 302 into the combined cavity of the two, and then threading the nut on the bottom end of the bolt 302, the bolt 302 can be connected in the positioning hole 104 and the threaded hole. By inserting the bolt 302, the position of the slider 3 in the slide groove 103 can be fixed, so that the end of the slider 3 inserted into the docking interface 204 remains fixed, and the displacement limit of the connection between the foundation beam 1 and the foundation column 2 in the upper and lower directions can be set, thereby improving the connection firmness of the foundation beam 1 and the foundation column 2.

[0058] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
