[0023] Embodiment

[0024] As Figures 1-3As shown in the figure, a connecting device for bridge assembly used in municipal bridge engineering proposed by an embodiment of the present utility model includes a pier 1 and a bridge deck 2 to be connected. A socket 3 is sleeved on the pier 1. The socket 3 is composed of two halves spliced together. A connecting buckle 4 is provided on the socket 3. A positioning pin 5 is inserted into the connecting buckle 4. A lever arm 6 is fixedly connected to the side of the socket 3. A reinforcing rib 7 is inserted in the middle of the lever arm 6. One end of the reinforcing rib 7 is connected to a tension device. The tension device includes an end cap 8 fixed to the reinforcing rib 7. A telescopic rod 9 is provided in the middle of the end cap 8. A connecting cover 10 is fixed to the telescopic end of the telescopic rod 9. A tension spring 11 is fixed between the connecting cover 10 and the end cap 8;

[0025] Among them, during splicing, the bearing functions of the socket 3 and the lever arm 6 are used for assistance. Through the tension device, the whole has a certain toughness. Because the connection between the socket 3 and the connecting buckle 4 is movable;

[0026] Socket 3: Sleeved on the pier 1, composed of two halves spliced together, used to connect the pier 1 and the bridge deck 2. A connecting buckle 4 is provided on the socket 3, and a lever arm 6 is fixedly connected to the side.

[0027] Connecting buckle 4: One end is concave and the other end is convex in shape, cooperating with each other, and there is a hole on it. Its shape and size are designed according to the diameter of the pier 1, and at least one hole can be provided. The connecting buckle 4 is used for inserting the positioning pin 5 to play a role in fixing the socket 3.

[0028] Positioning pin 5: Composed of a positioning column and a frame, the positioning column is inserted into the hole on the connecting buckle 4 to ensure the stable connection of the socket 3.

[0029] Lever arm 6: A reinforcing rib 7 is inserted in the middle. The lever arm 6 and the socket 3 jointly bear the load to assist in the installation of the connecting device.

[0030] Reinforcing rib 7: One end is connected to the tension device. The reinforcing rib 7 and the tension device are arranged in a surrounding manner. Four tension devices are provided in this embodiment. The reinforcing rib 7 can enhance the structural strength of the connecting device.

[0031] Tension device: Includes an end cap 8 fixed to the reinforcing rib 7, a telescopic rod 9 in the middle, and a connecting cover 10 fixed to the telescopic end of the telescopic rod 9. A tension spring 11 is fixed between the connecting cover 10 and the end cap 8. The tension device makes the whole have a certain toughness because the connection between the socket 3 and the connecting buckle 4 is movable. Such a design can, to a certain extent, adapt to the deformation and vibration of the bridge and enhance the stability and reliability of the connecting device.

[0032] During splicing, the bearing functions of the socket part 3 and the lever arm 6 are utilized for assistance, and a certain toughness is imparted to the whole through the tension device. The socket part 3 and the connection buckle 4 are movably connected. This movable connection method allows a certain degree of relative displacement to cope with the possible deformation or displacement of the bridge during use, reduces stress concentration at the connection, and improves the reliability and durability of the connection.

[0033] Generally speaking, through the coordinated action of components such as the socket part 3, the connection buckle 4, the positioning pin 5, the lever arm 6, the reinforcing rib 7, and the tension device, this connection device realizes the effective connection between the pier 1 and the bridge deck 2, and at the same time has a certain load-bearing capacity, toughness, and stability to meet the usage requirements of the municipal bridge;

[0034] The working principle is as follows:

[0035] First of all, the socket part 3 is sleeved on the pier 1, and the socket part 3 composed of two half pieces is initially fixed through the connection buckle 4 and the positioning pin 5. The lever arm 6 and the socket part 3 jointly bear the load from the bridge deck 2.

[0036] During normal use, the reinforcing rib 7 transmits the force to the tension device. When the bridge is subjected to external loads such as vehicle passage and wind load, certain deformation and vibration will occur.

[0037] Since the connection between the socket part 3 and the connection buckle 4 is movable and allows a certain relative displacement, a part of the energy can be absorbed and buffered.

[0038] The tension spring 11 in the tension device will produce elastic deformation when being stretched or compressed, and adapts to this deformation through the telescopic movement of the telescopic rod 9, playing a role in buffering and shock absorption. The end cap 8 and the connection cap 10 ensure the stable operation of the tension spring 11.

[0039] The combined action of the reinforcing rib 7 and the circumferentially arranged tension device makes the whole connection device have a certain toughness and adaptability, can effectively disperse and absorb the stress generated by the load, ensure the firmness and reliability of the connection between the pier 1 and the bridge deck 2, reduce fatigue damage at the connection, and extend the service life of the bridge.

[0040] As Figure 2 shown, in some embodiments, one end of the connection buckle 4 is concave and the other end is convex, which are matched with each other and are provided with holes; the concave-convex fit can make the two connection buckles 4 fit tightly, reduce the relative movement of the connection part in the horizontal direction, and improve the firmness of the connection.

[0041] In this embodiment, the shape and size of the connecting buckle 4 are designed according to the diameter of the bridge pier 1. At least one hole can be provided on the connecting buckle. If the diameter of the bridge pier 1 is large, a larger-sized connecting buckle 4 may be required, and in order to fix it more firmly, multiple holes will be provided to insert the positioning pins 5. For a bridge pier 1 with a smaller diameter, the connecting buckle 4 is correspondingly smaller, and the number of holes may be less, but there is at least one to ensure the basic fixing requirement. Such a design has flexibility, can adapt to the connection requirements of different specifications of bridge piers 1, and improves the versatility and practicality of the connecting device.

[0042] In this embodiment, the positioning pin 5 is composed of a positioning column and a frame. The positioning column is inserted into the hole on the connecting buckle 4. The positioning column is the main part that plays a role in fixing and connecting, and it is directly inserted into the hole on the connecting buckle 4. By inserting the positioning column into the hole, the locking and fixing of the connecting buckle 4 can be achieved, preventing the connecting buckle 4 from loosening, displacing or detaching during the working process.

[0043] In this embodiment, the reinforcing ribs 7 and the tension devices are in a surrounding form, and four tension devices are provided. The reinforcing ribs 7 and the tension devices connected thereto are annularly distributed around components such as the bridge pier 1 or the socket 3. This surrounding arrangement can make the transmission and dispersion of force more uniform, providing support and tension for the connection of the bridge from all directions.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
