Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

As shown in fig. 1, a structural diagram of a bridge deck supporting structure of a steel box girder according to an embodiment of the present invention includes a base 1, a supporting platform 8, a supporting mechanism 100 and a reinforcing mechanism 200, wherein the supporting mechanism 100 is mounted on the supporting platform 8 and is used for providing support for a bridge body 11; the reinforcing mechanism 200 is disposed between the base 1 and the supporting platform 8 for improving the stability of the supporting mechanism 100.

In an embodiment of the present invention, the supporting mechanism 100 is capable of resisting acting forces from different directions during supporting the bridge 11, so that the bridge 11 does not shake during building, and the reinforcing mechanism 200 is further provided for improving the load bearing capacity of the supporting mechanism 100 during working.

In an example of the present invention, the bridge 11 is placed on the supporting mechanism 100 during the installation process, and no matter the bridge is subjected to the acting force in the vertical direction or the inclined direction, the bridge can be supported by the supporting mechanism 100, so that the bridge 11 is not subjected to uneven stress and shaking in the installation process, which may affect the installation process of the bridge 11.

As shown in fig. 1 and 3, as a preferred embodiment of the present invention, the supporting mechanism includes a positioning column 12 fixedly installed on the supporting table 8, a connecting rod 13 disposed on the positioning column 12 at an equal angle, and a cross plate 14 and a ball head 15 symmetrically installed at the top end of the connecting rod 13;

the ball head 15 is movably connected with a spherical support 16 arranged at the corner of the bridge body 11;

the top ends of the transverse plate 14 and the positioning column 12 are both arranged at the bottom of the bridge body 11;

the positioning column 12 is provided with a swing rod 17, and the swing rod 17 is connected with a sleeve 18 sleeved on the connecting rod 13.

In an embodiment of the present invention, when the bridge body 11 is displaced to one side due to uneven stress during installation, the spherical support 16 is driven to move, and further drives the ball 15 and the connecting rod 13 to deflect along the positioning post 12, and at the same time, the connecting rod 13 is prevented from moving under the pulling of the swing rod 17, so that the bridge body 11 is kept stable to the maximum extent, and the accident of falling during installation is avoided, thereby improving the installation performance of the operation, and when the bridge body 1 is warped, the transverse plate 14 on the other side is driven to swing, and the connecting rod 13 on the side is also driven to move.

As shown in fig. 1, as another preferred embodiment of the present invention, the supporting mechanism 100 further includes supporting rods 7 symmetrically installed on the supporting platform 8, and side plates 10 fixedly installed at the top ends of the supporting rods 7;

the support rod 7 is provided with an inclined rod 9 for enhancing the compressive strength;

and a backing plate is arranged between the side plate 10 and the bridge body 11.

In one example of the present invention, when the rod 11 is displaced in the vertical direction, a force is applied to the support rod 7 through the side plate 10, a part of the force is offset by the inclined rod 9, and a part of the force is offset again by the reinforcing mechanism 100 at the bottom, so that the support rod 7 can maintain the stability of the dry rod body under the stress.

As shown in fig. 1 and 2, as another preferred embodiment of the present invention, the base 1 is connected to the support platform 8 through a first upright post 2 and a second upright post 3, and the reinforcing mechanism 200 disposed on the first upright post 2 and the second upright post 3 includes a rib plate 4, and a reinforcing frame 5 vertically mounted on a side surface of the rib plate 4;

and the top end of the rib plate 4 is provided with a mounting groove 6 for positioning the support rod 7.

In an embodiment of the present invention, since the support rod 7 and the support platform 8 are slidably disposed in this embodiment, a slight displacement occurs on the support rod 7 when a force is applied to the support rod 8, the rib plate 4 disposed at the bottom bears a pressure transmitted by the bridge body 11 through the support rod 7, and the reinforcing frame 5 mounted on the side surface of the rib plate 4 can also keep the rib plate 4 from deforming during the force application.

In summary, when the bridge 11 is displaced to one side due to uneven stress during installation, the spherical support 16 is driven to move, and further drives the ball head 15 and the connecting rod 13 to deflect along the positioning post 12, and when the bridge 1 is warped, the transverse plate 14 on the other side is driven to swing, and also drives the connecting rod 13 on the side to move, when the bridge 11 is displaced in the vertical direction, an acting force is applied to the supporting rod 7 through the side plate 10, the inclined rod 9 counteracts a part of the acting force, the supporting rod 7 and the supporting platform 8 are arranged in a sliding manner, so that the supporting rod 7 is slightly displaced along the supporting platform 8 when the supporting rod 7 is stressed, the rib plate 4 arranged at the bottom bears the pressure transmitted by the bridge 11 through the supporting rod 7, and the reinforcing frame 5 arranged on the side surface of the rib plate 4 can keep the rib plate 4 from deforming during the stress process, thereby keeping the bridge 11 stable to the maximum extent,

it will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
