The invention relates to mounting equipment of a beam falling prevention stopping block and a construction method thereof. The mounting equipment comprises a hoisting mechanism, a steel rope and a manual hoist, wherein the hoisting mechanism is a universal cart and comprises a cart frame and four wheels; the cart frame is connected with a pincer-shaped clamping tool, and the rear part of the cartframe is connected with an armrest; the four wheels include a pair of front large wheels and a pair of rear small wheels; the rear small wheels are universal wheels; cart frame longitudinal beams areconnected between wheel frames of the front large wheels and wheel frames of the rear small wheels at the left side and the right side; a door-shaped frame is connected between the two cart frame longitudinal beams; the manual hoist is suspended and connected with a stopping block bracket; the stopping block bracket has a frame structure in a shape like the Chinese character ri, which is formed by fixedly connecting two kinds of profile steel and three kinds of short profile steel; each grid supports a beam falling prevention stopping block, and the short profile steel in the middle of a frame in the shape like the Chinese character ri is connected with a lifting beam. The equipment has the characteristics of high working efficiency, simple structure and convenient operation, can be operated and used in narrow spaces of the top of a bridge pier and the bottom of a box beam and can easily and conveniently mount the beam falling prevention stopping block in the needed position.
Description
technical field [0001] The invention relates to special equipment for installing anti-falling beam stoppers and a construction method thereof. Background technique [0002] In order to avoid catastrophic damage such as falling girders and limit the relative deformation between the box girder and the top of the bridge pier during a major earthquake, anti-falling girder blocks are usually installed in the box girder construction measures. The existing anti-falling beam stoppers are irregular steel components, which are installed on the pre-embedded steel plates at the bottom of the box girder girder, and four pieces need to be installed for each beam hole. During installation, after the plane with the bolt holes of the anti-drop beam block is accurately aligned with the bolt holes of the pre-embedded steel plate at the bottom of the box girder, they are connected with bolts to complete the installation. When the anti-fall beam stopper does not function, the box girder can vib...
