Description

Technical Field

[0001] This utility model relates to the field of prefabricated subway station construction technology, and in particular to a top-level node connection structure for prefabricated subway station components. Background Technology

[0002] Prefabricated reinforced concrete structures mainly rely on wet joint construction. Although this method has lower requirements for on-site construction and installation technology, it also has obvious drawbacks. Taking the top corner joint connection as an example, since the existing top corner joints are usually orthogonal, such as the dry connection structure of the top corner joint of the prefabricated concrete frame with bolt connection disclosed in patent document CN213233788U, there is a lack of adjustment mechanism. Therefore, for the construction of top corner joints with shape requirements, full-span scaffolding is still the main method.

[0003] A top-level node connection structure for precast components in subway stations is provided, which can adjust the connection angle of the top-level nodes, making the assembly of concrete components more flexible and convenient. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a top-level node connection structure for prefabricated components of subway stations, which effectively solves the problem that the existing top-level node connection structure for prefabricated components of subway stations cannot adjust the angle.

[0005] The technical solution includes a base on which a vertical I-beam is fixed. An opening is formed in the middle rib of the I-beam, and a cylindrical shell arranged in the front-to-back direction is located inside the opening. Multiple longitudinal ribs run through the cylindrical shell, and the ends of the longitudinal ribs pass through the side plates of the I-beam and are placed outside the side plates of the I-beam. The multiple longitudinal ribs fix the cylindrical shell and the I-beam in place. A vertical connecting plate is located on the right side of the cylindrical shell, and multiple studs are fixed on the side of the connecting plate near the cylindrical shell. The studs pass through the cylindrical shell and are placed on the left side of the cylindrical shell, and a tightening nut is screwed on the left end of the stud.

[0006] Preferably, the cylindrical shell has multiple circumferentially distributed first holes on its front and rear sidewalls; the cylindrical shell can be fixed at different angles by adjusting the longitudinal ribs to cooperate with different first holes.

[0007] Preferably, the cylindrical shell has a plurality of second holes evenly distributed around its circumference on its outer circumferential surface, through which the stud penetrates the cylindrical shell.

[0008] Preferably, the outer sides of the front and rear ends of the cylindrical shell are fitted with semi-circular buckle plates, with pins in the middle of the buckle plates, and the cylindrical shell is provided with multiple third holes corresponding to the pins; the ends of the buckle plates are fixed to the ribs of the I-beams by bolts.

[0009] This utility model has an ingenious structure that allows for adjustment of the connection angle of the top-level nodes, making the assembly of concrete components more flexible and convenient. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 6 The present invention includes a base 1, on which a vertical I-beam 2 is fixed. An opening is provided in the middle rib of the I-beam 2, and a cylindrical shell 3 arranged in the front-back direction is provided in the opening. Multiple longitudinal ribs 4 pass through the cylindrical shell 3, and the ends of the longitudinal ribs 4 pass through the side plate of the I-beam 2 and are placed on the outside of the side plate of the I-beam 2. The multiple longitudinal ribs 4 fix the cylindrical shell to the I-beam 2. A vertical connecting plate 5 is provided on the right side of the cylindrical shell 3. Multiple studs 6 are fixed on the side of the connecting plate 5 near the cylindrical shell 3. The studs 6 pass through the cylindrical shell 3 and are placed on the left side of the cylindrical shell 3. A clamping nut 7 is screwed on the left end of the stud 6.

[0018] In order to achieve the adjustment of the cylindrical shell 3 at different angles, and thus to achieve the assembly of prefabricated top beams at different angles, multiple first holes 8 are evenly distributed in a circle on the front and rear side walls of the cylindrical shell 3; by adjusting the longitudinal ribs 4 to cooperate with different first holes 8, the cylindrical shell 3 can be fixed at different angles.

[0019] In order to further realize the angle adjustment of the cylindrical shell 3, multiple second holes 9 are provided on the outer circular surface of the cylindrical shell 3 in a circumferentially distributed manner, and the stud 6 passes through the second holes 9 to penetrate the cylindrical shell 3.

[0020] To prevent the longitudinal ribs 4 from bending and to increase the strength of the top corner connection, the outer sides of the front and rear ends of the cylindrical shell 3 are fitted with semi-circular buckle plates 10. The buckle plates 10 have pins 11 in the middle. The cylindrical shell 3 is provided with multiple third holes corresponding to the pins 11. The ends of the buckle plates 10 are fixed to the ribs of the I-beam 2 by bolts.

[0021] It is worth noting that the multiple first holes 8 and multiple second holes 9 in this solution are both for angle adjustment, making them flexible and convenient to use.

[0022] In use, first fix the base 1, then place the cylindrical shell 3 into the opening on the rib plate, and then insert multiple longitudinal ribs 4 through the side wall of the I-beam 2 and the cylindrical shell 3 to fix them in place. If necessary, stop blocks or limit blocks can be set on the longitudinal ribs 4 to limit their movement and prevent them from moving axially. Then, insert multiple studs 6 on the connecting plate 5 through the cylindrical shell 3, and then screw the clamping nut 7 onto the studs 6. The connecting plate 5 is now installed. Finally, fasten the buckle plate 10 onto the cylindrical shell 3, insert the pin on the buckle plate 10 into the corresponding third hole, and then use bolts to fix the end of the buckle plate 10 to the rib plate of the I-beam 2. The installation is now complete. Install and fix the end of the precast beam to be assembled onto the connecting plate 5, and wait for the next step of construction.

[0023] To accommodate different top beam angles, simply adjust the angle of the connecting plate 5. Specifically, when installing the connecting plate 5, insert the stud 6 into the corresponding second hole 9. Similarly, the longitudinal reinforcement 4 can be inserted into different first holes 8 to adjust the top beam installation angle.
