Abstract

The invention discloses a temporary passing bridge for construction. The temporary passing bridge comprises a first bridge body, a second bridge body and a third bridge body. The upper end of the first bridge body, the upper end of the second bridge body and the upper end of the third bridge body are provide with passing flat plates. The bottom of the first bridge body and the bottom of the third bridge body are provided with lead screw nut drill bit devices. The left end of the first bridge body and the right end of the third bridge body are both provided with a hand-operated type lead screw nut pulling device. Each lead screw nut drill bit device comprises a first lead screw nut pair with the bottom provided with a drill bit. The upper end of each first lead screw nut pair is provided with an electric motor device enabling the first lead screw nut pair to advance, stretch and retract. Each hand-operated type lead screw nut drilling device comprises a groove. Cross plates are arranged in the grooves, wherein the bottom of each cross plate is provided with a corresponding hand-operated type lead screw nut pair. The movable end of each cross plate is provided with a bolt fixing hole. According to the temporary passing bridge, through splicing and transverse and a longitudinal lead screw nut system, the installation mode of the bridge and the connecting mode between the bridge and a river bed can be greatly simplified, and the temporary passing bridge is safe and firm.

Description

technical field [0001] The invention relates to a building passing device, in particular to a temporary building passing bridge. Background technique [0002] When building bridges on some rivers with small widths, sometimes due to the needs of temporary traffic, a temporary bridge for traffic must be erected near the bridge under construction. The bridge can also be used for auxiliary bridge construction. The usual way is to erect A simple bridge made of wood or bamboo will be dismantled after the formal bridge is built, but at the same time, the safety hazards of such a bridge are relatively large, especially in rivers where the river water often fluctuates. . Contents of the invention [0003] The present invention aims at the above problems and proposes a temporary access bridge for construction. The temporary access bridge is simple to install, firm to use and greatly improved in safety. [0004] In order to achieve the above-mentioned technical purpose, the present...
