[0002] With the rapid development of the bridge construction industry, it is becoming increasingly common to build bridges using precast bridge slabs. The connection of precast bridge slabs has also become an important issue in the construction process. Traditional precast bridge slab joint connection structures have low installation accuracy, require a large amount of work during installation, are difficult to guarantee connection strength, cannot achieve good stress performance, and have low seismic resistance. Therefore, a connection structure with elastic connection is needed. A connection structure with elasticity during vibration can improve seismic resistance. Summary of the Invention

[0003] The purpose of this application is to provide a bridge precast slab joint connection structure to solve the above problems. It uses elastic elements to connect two precast slabs, improves seismic resistance, and has a detachable design for easy installation and disassembly, and allows for the replacement of aging elastic elements.

[0004] This application achieves the above objectives through the following technical solutions:

[0005] A precast bridge slab joint connection structure includes a precast slab, a connector, a connecting plate, a top plate, an elastic element, a groove, and a perforation. The connecting plate is fixedly connected to the connector. The connecting plate is provided with multiple sets of limiting elements. The bottom of the limiting element is provided with a base plate that is fixedly connected to the limiting element and the connecting plate. The top of the limiting element is provided with a detachable top plate. Fasteners are provided between adjacent limiting elements to secure the top plate. The elastic element is provided with a protrusion that can be inserted into the limiting element and a perforation through which the fastener can pass.

[0006] Furthermore, the connector includes a mounting plate, a reinforcing member, a connecting bolt, and a connecting nut.

The reinforcing member is fixedly connected to the surface of the mounting plate and is fixedly connected to the connecting plate.

[0007] Furthermore, the limiting member consists of two limiting plates arranged at opposite inclinations to form a tapered shape with a narrow opening on the side opposite to the connecting member. The elastic member is provided with a groove for the limiting plate to pass through to form a tapered protrusion that fits the limiting member.

[0008] Furthermore, the fasteners include fastening bolts and fastening nuts. The bottom end of the fastening bolt is fixedly connected to the base plate, the top end of the fastening bolt penetrates the top plate, and a fastening nut is screwed onto the top of the fastening bolt.

Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] like Figure 1-4As shown, a bridge precast slab joint connection structure includes a precast slab 1, a connector, a connecting plate 6, a top plate 11, an elastic member 12, a groove 13, and a through hole 14. The connecting plate 6 is fixedly connected to the connector to support the limiting member. Multiple sets of limiting members are provided on the connecting plate 6. The bottom of the limiting member is provided with a bottom plate 8 that is fixedly connected to the limiting member and the connecting plate 6. The top of the limiting member is provided with a detachable top plate 11. Fasteners are provided between adjacent limiting members to fasten the top plate 11. The elastic member 12 is provided with a protrusion that can be inserted into the limiting member and a through hole 14 for the fastener to pass through.

[0021] Specifically, the limiting member is fixedly connected to the connecting plate 6, and is fixed to the top and bottom of the limiting member by the cooperation of the bottom plate 8 and the top plate 11. The protrusion of the elastic member 12 is inserted into the inside of the limiting member, and the elastic member 12 is fixed by the fastener passing through the elastic member 12. The elastic member 12 can be disassembled and replaced.

[0022] Furthermore, the connecting components include a mounting plate 2, a reinforcing member 3, a connecting bolt 4, and a connecting nut 5. The precast plate 1 has a pre-embedded connecting bolt 4. The mounting plate 2 has a through hole through which the connecting bolt 4 can pass. The connecting bolt 4 is screwed with a connecting nut 5 that can fasten the mounting plate 2. The reinforcing member 3 is fixedly connected to the surface of the mounting plate 2. The reinforcing member 3 is fixedly connected to the connecting plate 6.

[0023] Specifically, the precast slab 1 has pre-embedded connecting bolts 4. When the mounting plate 2 is installed on the precast slab 1, the connecting bolts 4 pass through the mounting plate 2, and then the mounting plate 2 is fastened by the connecting nuts 5. The mounting plate 2 and the reinforcing member 3 are an integral structure, which means that the mounting plate 2 and the reinforcing member 3 are fixedly installed.

[0024] Furthermore, the limiting member consists of two limiting plates 7 arranged at opposite inclinations to form a tapered shape with a narrow opening on the side facing away from the connector. The elastic member 12 is provided with a groove 13 through which the limiting plate 7 passes to form a tapered protrusion that matches the limiting member.

[0025] Specifically, the two limiting plates 7 of each set of limiting members are set vertically, with one side of the inclined constricted opening of the two limiting plates 7 being open, and the other side being fixedly connected to the connecting plate 6, so as to limit the protrusions on the elastic member 12.

[0026] Furthermore, the fasteners include a fastening bolt 9 and a fastening nut 10. The bottom end of the fastening bolt 9 is fixedly connected to the base plate 8, the top end of the fastening bolt 9 penetrates the top plate 11, and the fastening nut 10 is screwed onto the top of the fastening bolt 9.

[0027] Specifically, when installing the elastic element 12, the protrusion is inserted into the inner side of the limiting element, and at the same time the fastening bolt 9 passes through the through hole 14. Then, the fastening nut 10 is tightened to secure the top plate 11, so as to facilitate the installation and fixing of the elastic element 12.

[0028] Furthermore, the elastic element 12 is made of rubber, which has elasticity, thereby improving shock resistance.

[0029] In the above structure, the mounting plate 2 is fastened to the connecting bolt 4 by the connecting nut 5 to connect to the precast plate 1. Then, the elastic element 12 is installed between the limiting plates 7, so that the limiting plates 7 are inserted into the groove 13 and the fastening bolt 9 is inserted into the through hole 14. Then, the top plate 11 is installed on the elastic element 12 to press and fasten the elastic element 12. Then, the fastening nut 10 is screwed onto the fastening bolt 9 to fix the elastic element 12, thus completing the installation. This allows the two precast plates 1 to be connected and fixed. The elastic element 12 can be compressed and deformed to meet the relative movement requirements between the precast plates 1 during vibration, and has a certain seismic performance.
