The invention discloses a lifting appliance for mounting a bridge floor steel bottom plate between steel truss girder sections of a plate-truss structure and a construction process. Characterized in that; the lifting appliance is composed of a main beam, a connecting plate, supporting legs, inclined struts, walking wheels, rails and lifting lugs. The rated lifting weight of the device is 5 t. The lower ends of the supporting legs are provided with walking wheels and arranged on a rail, the upper ends of the inclined struts are connected with a connecting plate at the lower end of the main beam, and the lower ends of the inclined struts are fixed to the corresponding supporting legs. The mounting efficiency and precision of the steel bottom plate between the steel truss girder sections are improved through the movable bridge floor steel bottom plate mounting lifting appliance. The method has the following beneficial effects that (1) the bridge deck slab is integrally and rapidly installed, and the installation efficiency of the bridge deck slab is improved; (2) the construction safety risk on the steel truss girder is reduced through the quick installation of the bridge deck slab; the support is simple in structure, easy to machine and convenient to operate.
