Detailed Description

The utility model is further illustrated by the following examples and figures:

in the description of the embodiments of the present invention, it should be understood that the terms "top," "bottom," and the like refer to orientations and positional relationships illustrated in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention. In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, e.g., as a fixed connection, a detachable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

In an embodiment of the present invention, as shown in fig. 1, a structural diagram of a welding deformation correction device for a bridge bottom plate includes: the stiffening rib 1 is used for supporting the jack 5, and the stiffening rib 1 can be made of leftover bits and pieces of a steel structure bridge; a support panel provided on the stiffener 1 for supporting the jack 5; and the clamping mechanism is arranged on the stiffening rib 1 and used for clamping the bridge bottom plate 7.

Specifically, the top of the stiffening rib 1 is provided with a notch, the size of the notch is slightly larger than that of the jack 5, and the plane of the notch needs to be flat, so that the contact surfaces of the supporting panel 3 and the jacking panel 2 with the jack 5 are horizontal or vertical.

The supporting mechanism comprises a top pressure panel 2 and a supporting panel 3, the top pressure panel 2 is vertically welded on a plane at the position of the notch, the included angle between the top pressure panel 2 and the horizontal plane of the stiffening rib 1 is measured at any time during welding, a 90-degree vertical state is kept, the thickness of the top pressure panel 2 is the length of the notch minus the length of the jack 5, and the optimal thickness is (20-25 mm) and is used for jacking the jack 5. The horizontal welding of support panel 3 is at incision department plane, measures the contained angle of support panel 3 and the vertical face of stiffening rib 1 at any time during the welding, guarantees 90 perpendicular, and the length of support panel 3 is the length of incision department for support jack 5.

The bottom of the stiffening rib is provided with a groove for clamping a bridge bottom plate 7, the depth of the groove is greater than the extension part of the bridge bottom plate 7 contacted with the steel bridge 6, and the height of the groove is the thickness of the pressure applying panel 4 plus the thickness of the bridge bottom plate 6.

The clamping mechanism comprises a pressing panel 4 for clamping the bridge bottom plate 7, the pressing panel is horizontally welded on the upper surface of the inner side of the groove, certain pressure is applied to the bridge bottom plate 7, the bridge bottom plate 7 is clamped and fixed, and the correction device is prevented from moving to cause correction errors.
