Description

Technical Field

[0001] This utility model belongs to the technical field of concrete box girder bridges, and particularly relates to a transverse connection structure for a prestressed concrete continuous box girder bridge. Background Technology

[0002] A concrete box girder bridge is a bridge with long, hollow concrete trusses as crossbeams. Its main girder is composed of hollow box-shaped beams. This design makes the bridge both lightweight and strong. Concrete box girder bridges can be divided into various types according to their structural characteristics and application scenarios, such as inverted trapezoidal box girder bridges, separated box girder bridges, steel-deck box girder bridges, double-layer box girder bridges, double-web box girder bridges, inclined-web box girder bridges, and composite box girder bridges. The cross-section of a concrete box girder bridge is box-shaped, containing a straight top plate, two side walls, and a bottom plate, similar to a closed box. This cross-sectional shape gives the bridge excellent torsional stiffness and integrity, and it can adapt well to various complex structures, such as curved beams, various complex variable cross-section continuous beams, and continuous rigid frames. Concrete box girder bridges occupy an important position in bridge engineering due to their unique structural characteristics and wide range of applications.

[0003] However, the concrete continuous box girder bridges currently in use do not have transverse connection structures, which makes it very inconvenient to connect multiple sets of concrete continuous box girder bridges laterally. Precise positioning is difficult, and construction personnel need to make repeated adjustments. Therefore, it is necessary to provide a transverse connection structure for prestressed concrete continuous box girder bridges to solve the above problems. Summary of the Invention

[0006] As a further solution of this utility model, the main body of the box girder bridge is configured as a trapezoidal structure, and the support block is fixedly installed at the connection between the top of the main body of the box girder bridge and the bottom of the top plate. Four rows of support blocks are symmetrically installed on both sides of the top of the main body of the box girder bridge. The support block is configured to fit the shape of the connection between the top plate and the main body of the box girder bridge. The main body of the box girder bridge and the top plate are fixedly connected. The support block can increase the strength of the connection between the main body of the box girder bridge and the top plate.

[0007] As a further solution of this utility model, five sets of connecting blocks are symmetrically installed on the right side of the top plate, and five sets of connecting slots are correspondingly opened on the left side of the top plate. The locking rod is fixedly installed in the locking slot opened on the connecting block. Both the connecting block and the connecting slot are set as T-shaped structures, so that the connecting block cannot be disengaged from the connecting slot laterally.

[0008] As a further solution of this utility model, the connecting body is configured as a trapezoidal structure identical to the main body of the box girder bridge, and the mounting groove opened on the left side of the main body of the box girder bridge is configured as a structure adapted to the connecting body, so that the two sets of main bodies of the box girder bridge can be assembled together through the connecting body.

[0009] As a further solution of this utility model, a fixing hole is provided on the left side of the main body of the box girder bridge, the fixing hole penetrates the mounting groove, a fixing hole is provided on the connecting body, the mounting groove and the fixing hole on the connecting body are in a connected state, the locking pin is fixedly installed therein, and thirteen sets of locking pins are symmetrically installed in the mounting groove and the connecting body, thereby fixing the connecting body in the mounting groove.

[0010] As a further solution of this utility model, the size of the support frame is adapted to the inner dimensions of the box girder bridge body. The support frame is welded from multiple sets of horizontal and vertical support plates. The two sides and bottom of the support frame are fixedly connected to the inner sides and bottom of the box girder bridge body, thereby effectively increasing the strength of the box girder bridge body itself through the support frame.

[0011] Compared with related technologies, the transverse connection structure for a prestressed concrete continuous box girder bridge provided by this utility model has the following beneficial effects:

[0012] 1. This utility model involves installing a connector on the right side of the main body of a box girder bridge, while an installation groove is provided on the left side of the main body. By horizontally installing the connector on the right side of one set of main bodies into the installation groove on the left side of another set of main bodies, the two sets of main bodies can be assembled together. A fixing hole penetrating the installation groove is provided on the left side of the main body, and a fixing hole is provided on the connector. The installation groove and the fixing hole on the connector are connected, and a locking pin is fixedly installed therein, thereby fixing the connector in the installation groove. This allows the two sets of main bodies to be fixedly assembled together. This structure makes it very convenient to position multiple sets of main bodies during splicing, eliminating the need for repeated adjustments by the user.

[0013] This utility model installs five sets of connecting blocks on the right side of the top plate and five sets of connecting slots on the left side of the top plate. By installing the connecting blocks installed on the right side of one set of top plates into the connecting slots on the left side of another set of top plates, the two sets of top plates can be horizontally spliced ​​together. Both the connecting blocks and the connecting slots are set as T-shaped structures, so that the connecting blocks cannot be horizontally separated from the connecting slots, and thus the two sets of top plates assembled together cannot be horizontally separated.

[0014] This utility model symmetrically installs two sets of support frames inside the main body of the box girder bridge. The size of the support frames is adapted to the inner dimensions of the main body of the box girder bridge. The support frames are welded together from multiple sets of horizontal and vertical support plates. The two sides and bottom of the support frames are fixedly connected to the inner sides and bottom of the main body of the box girder bridge. Thus, the support frames can effectively increase the strength of the main body of the box girder bridge and extend its service life. Attached Figure Description

[0023] Please refer to the following: Figure 1-6 A transverse connection structure for a prestressed concrete continuous box girder bridge includes a top plate 1, a box girder bridge body 2 installed at the bottom of the top plate 1, a connecting block 3 installed on the right side of the top plate 1, a connecting groove 4 opened on the left side of the top plate 1, a locking rod 5 installed in the connecting block 3, a connecting body 6 installed on the right side of the box girder bridge body 2, an installation groove 7 opened on the left side of the box girder bridge body 2, two sets of support frames 8 symmetrically installed inside the box girder bridge body 2, multiple sets of support blocks 9 installed between the top plate 1 and the box girder bridge body 2, and multiple sets of locking pins 10 installed on the left side of the box girder bridge body 2.

[0024] Preferably, the main body 2 of the box girder bridge is configured as a trapezoidal structure, and the support block 9 is fixedly installed at the connection between the top of the main body 2 of the box girder bridge and the bottom of the top plate 1. Four rows of support blocks 9 are symmetrically installed on both sides of the top of the main body 2 of the box girder bridge. The support block 9 is configured to fit the connection between the top plate 1 and the main body 2 of the box girder bridge. The main body 2 of the box girder bridge and the top plate 1 are fixedly connected. The support block 9 can increase the strength of the connection between the main body 2 of the box girder bridge and the top plate 1.

[0025] Preferably, five sets of connecting blocks 3 are symmetrically installed on the right side of the top plate 1, and five sets of connecting slots 4 are correspondingly opened on the left side of the top plate 1. By installing the connecting blocks 3 installed on the right side of one set of top plates 1 into the connecting slots 4 opened on the left side of another set of top plates 1, the two sets of top plates 1 can be horizontally spliced ​​together. The locking rod 5 is fixedly installed in the locking slot opened on the connecting block 3, thereby increasing the strength of the connecting block 3 itself. Both the connecting block 3 and the connecting slot 4 are set as T-shaped structures, so that the connecting block 3 cannot be horizontally separated from the connecting slot 4, and thus the two sets of top plates 1 assembled together cannot be horizontally separated. When making horizontal connections of multiple sets of this device, it is necessary to connect the top plates 1 and the box girder bridge body 2 of multiple sets of this device separately, and then fix and assemble the connected top plates 1 and the connected box girder bridge body 2 together.

[0026] Preferably, the connecting body 6 is configured as a trapezoidal structure identical to that of the box girder bridge body 2, and the mounting groove 7 opened on the left side of the box girder bridge body 2 is configured as a structure adapted to the connecting body 6. By horizontally installing the connecting body 6 on the right side of one set of box girder bridge bodies 2 into the mounting groove 7 opened on the left side of another set of box girder bridge bodies 2, the two sets of box girder bridge bodies 2 can be assembled together.

[0027] Preferably, a fixing hole is provided on the left side of the box girder bridge body 2, and the fixing hole passes through the mounting groove 7. A fixing hole is also provided on the connecting body 6. After the connecting body 6 is installed into the mounting groove 7, the mounting groove 7 and the fixing hole on the connecting body 6 are connected. The locking pin 10 is fixedly installed therein. Thirteen sets of locking pins 10 are symmetrically installed in the mounting groove 7 and the connecting body 6, thereby fixing the connecting body 6 in the mounting groove 7. This allows the two sets of box girder bridge bodies 2 to be fixedly assembled together. Then, the assembled multiple sets of top plates 1 are installed on the top of the assembled multiple sets of box girder bridge bodies 2, which can realize the lateral connection of multiple sets of this device. Under the action of the connecting block 3, the connecting body 6 and the locking pin 10, the assembled multiple sets of this device will not separate, thus making the device highly safe.

[0028] Preferably, the size of the support frame 8 is adapted to the inner dimensions of the box girder bridge body 2. The support frame 8 is welded from multiple sets of horizontal and vertical support plates. The two sides and bottom of the support frame 8 are fixedly connected to the inner sides and bottom of the box girder bridge body 2. Thus, the support frame 8 can effectively increase the strength of the box girder bridge body 2 and extend its service life.
