Description

The high bolt of a kind of girder steel rod member assembly unit Moveable telescopic is executed stubborn platform
Technical field
The present invention relates to a kind of construction equipment of bridge subsection deck-molding bolt construction, relate in particular to a kind ofly set up conveniently, the high bolt of girder steel rod member assembly unit that efficiency of construction is high executes stubborn platform.
Background technology
Have because high-strength bolt connects that construction is simple, stress performance is good, replaceable, endurance and the unlikely advantage such as loosening under dynamic load function, development along with domestic and international steel truss girder bridge, high-strength bolt more and more is applied to the assembly unit between each rod member of steel truss girder, but because a gusset plate high-strength bolt quantity is very large, each rod member joint is many again, so this has brought a lot of problems for the construction of high-strength bolt.High-strength bolt construction need to have a space enough large, and the operation platform of safe enough, and conventional employing suspension bracket is as operation platform, and is not only loaded down with trivial details, and along with the advancing of steel truss girder construction stage, has inevitably brought the problem of advanced in unison.If adopt the loop wheel machine lifting to advance, take working sources and time.
Summary of the invention
The present invention is mainly for the existing above-mentioned technical problem of prior art, and the high bolt of girder steel rod member assembly unit that provide a kind of and set up conveniently, efficiency of construction is high is executed stubborn platform.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the high bolt of a kind of girder steel rod member assembly unit Moveable telescopic is executed stubborn platform, comprise steel pipe support, described steel pipe support bottom is provided with road wheel, top is provided with orthogonal two Telescopic sliding platforms, comprises the first sliding platform of the second sliding platform that described steel pipe support top vertically arranges and described the second sliding platform below horizontally set.
As preferably, be respectively equipped with the channel-section steel slideway between described the first sliding platform and the second sliding platform and steel pipe support.
As preferably, described the first sliding platform and the second sliding platform are arranged on groove steel rail by a sliding platform bearing respectively.
As preferably, be provided with the first platform diagonal brace between described the first sliding platform and steel pipe support, described the first platform diagonal brace is hinged with the first sliding platform and steel pipe support respectively.
As preferably, be provided with the diagonal brace faller between described the first platform diagonal brace and steel pipe support.
As preferably, be provided with the second platform diagonal brace between described the second sliding platform and steel pipe support, described the second platform diagonal brace is hinged with the first sliding platform and steel pipe support respectively.
The present invention has taked the sliding platform free-extension, according to gusset plate and steel truss girder web member position free-extension, in the construction main truss outside or during cross bearer place high-strength bolt, the first sliding platform is pulled out, and support with the first platform diagonal brace and diagonal brace faller, when the inboard high-strength bolt of construction main truss or walking reach, regain the first sliding platform and the first platform diagonal brace and diagonal brace faller.In the construction main truss outside or during needle beam place high-strength bolt, the second sliding platform is pulled out, and support with the second platform diagonal brace, when the inboard high-strength bolt of construction main truss or walking reach, withdrawal the second sliding platform and the second platform diagonal brace.The present invention has reduced the engineering time, and method is simple, and is workable, and the high bolt in the time of can being fit to the steel girder member bar assembly unit is executed stubborn, improved again high bolt simultaneously and executed stubborn work efficiency.
