Description

Technical Field

[0001] The utility model relates to the technical field of underground station structures, in particular to an integral underground station arch bridge top plate assembly structure. Background Art

[0002] With the advancement of urbanization, the use of urban roads is becoming increasingly tense. In the current urbanization construction process, subways, as an integral part of urban transportation, do not occupy surface area and are fast. Therefore, more and more cities choose to build subways. In the current subway construction process, the construction of underground stations is more applied to prefabricated building construction.

[0003] At present, underground station construction adopts prefabricated construction, which can greatly speed up the construction progress. However, in order to facilitate installation and maintain the supporting strength of the middle section of the arch bridge top plate, the arch bridge position of the current prefabricated monolithic underground station often adopts a two-section structure with rod reinforcement. However, at present, the middle section connection position of the arch bridge top plate is usually only equipped with horizontal rods, but there are no reinforcing rods perpendicular to the horizontal. Instead, the joint strength is enhanced by a socket structure during the prefabrication and assembly of the arch bridge top plate. However, since this method does not have a locking structure perpendicular to the horizontal, the load on both ends of the horizontal rod is relatively large, which increases the risk of long-term use.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-3As shown, an integral underground station arch bridge top plate assembly structure, the arch bridge top plate is composed of a first arch bridge 1 and a second arch bridge 2 that are relatively connected, the middle connection position of the first arch bridge 1 and the second arch bridge 2 is upwardly tilted, and matching reinforced connection components are provided on the opposite surfaces of the first arch bridge 1 and the second arch bridge 2, and the opposite ends of the first arch bridge 1 and the second arch bridge 2 can be connected by the reinforced connection components.

[0020] The above-mentioned reinforced connection assembly includes at least two pairs of slots 3. The side wall surface of the first arch bridge 1 is provided with at least two pairs of slots 3 arranged in a matrix. The corresponding slots 3 in the second arch bridge 2 are embedded with a connector. The connector passes through the side wall surface of the second arch bridge 2. The outside of the connector is wrapped with a concrete socket 5. The end of the connector extends out a sleeve 6, and the upper and lower ends of the sleeve 6 pass through the concrete socket 5.

[0021] During the specific implementation process, the opposite ends of the first arch bridge 1 and the second arch bridge 2 are inserted into the slot 3 through the concrete joint 5 on the connector. The tail end of the connector is a rectangular structure and is pre-buried in the head end of the second arch bridge 2 to enhance the connection stability and structural strength of the connector. After the concrete joint 5 and part of the connector are inserted into the slot 3, a longitudinal rod 7 is inserted into the slot 3 to pass through the sleeve 6. The connecting function of the longitudinal rod 7 is used to perform the first reinforcement of the connection between the first arch bridge 1 and the second arch bridge 2.

[0022] The reinforced connection assembly also includes a plurality of first pre-set holes 8 disposed horizontally and parallel to each other on the first arch bridge 1, and a plurality of second pre-set holes 9 disposed horizontally and parallel to each other on the second arch bridge 2. The first pre-set holes 8 and the second pre-set holes 9 are disposed in a one-to-one correspondence. A plurality of tension rods are inserted into the first pre-set holes 8 and the second pre-set holes 9 to achieve a tension connection between the first arch bridge 1 and the second arch bridge 2.

[0023] By making the positions of the first reserved hole 8 correspond to the second reserved hole 9 and utilizing the reverse pulling connection of the pulling rod, the opposite ends of the first arch bridge 1 and the second arch bridge 2 are pulled together in the horizontal direction, thereby making the slot 3 and the concrete seat 5 more tightly combined, serving as a second reinforcement method for the first arch bridge 1 and the second arch bridge 2.

[0024] Furthermore, a number of first reserved holes 8 are arranged in a linear array and staggered with the slots 3, so that the distribution of the rods is more uniform. The edge of the concrete joint 5 is a slope structure, and the end of the slot 3 is provided with a slope structure to facilitate plug-in. The tension rod includes a tension screw 10 that matches the diameter of the first reserved hole 8 and the second reserved hole 9 and a tension nut 11 threadedly connected to both ends of the tension screw 10. The tension nut 11 contacts the outside of the first reserved hole 8 and the second reserved hole 9, and through relative tightening, the first arch bridge 1 and the second arch bridge 2 are tightly connected. The longitudinal rod 7 is a rod with a threaded structure at the head end. The longitudinal rod 7 passes through the top of the first arch bridge 1, and a pre-buried threaded pipe 12 is provided in the bottom slot 3 and is threadedly connected to the longitudinal rod 7;

[0025] The longitudinal rod 7 is used to pass through multiple sleeves 6 at one time and is connected to the embedded threaded tube 12. While the longitudinal rod 7 is pulled and fixed, the limiting effect of the longitudinal rod 7 and the sleeve 6 is used to improve the tightness of the first arch bridge 1 and the second arch bridge 2.

[0026] From the above, it can be generally seen that the integral underground station arch bridge top plate assembly structure is suitable for the arch bridge top plate assembly of underground stations. During the docking connection process of the arch bridge top plates, in addition to setting up transverse connecting rods, vertical plug rods are used to penetrate multiple plug-in sleeves to achieve double fixation, effectively improving the tightness and structural strength of the joint position in the middle of the arch bridge top plate, and improving the safety of use and service life.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
