Description
Technical field
The utility model belongs to the bridge technology field.
Background technology
The general employing of prestressed concrete continuous beam construction set up the full hall scaffold formwork erection or passed through the Hanging Basket cantilever grouting.When bridge pier is higher or bridge under can only adopt the construction of Hanging Basket cantilever pouring can't set up scaffold the time.The cradle construction prerequisite is the complete 0# sections of must constructing on bridge pier, and the 0# segmental construction is generally by push up pre-buried built-in fitting at pier, and the load that installation bracket is born 0# sections bracketed part provides working space simultaneously.
General carriage commonly used is triangle, and rigidity and stability are not fine, low bearing capacity.
The high-altitude, 100 meters left and right in mountain area, wind-force is large, as adopts common triangle bracket, can not meet construction and safety requirements.
The utility model content
The purpose of this utility model is: a kind of new bracket is provided, has higher bearing capacity, stability, wind resistance.
The utility model purpose realizes by following technical proposals:
A kind of rectangle wind resistance carriage, on laying respectively at, under upper girder, lower girder, be positioned at described on, connect both two diagonal braces between lower girder, be connected and fixed diagonal brace and described on, the steel plate of putting more energy into of lower girder, and be located at described on, the anchor plate of termination, lower girder the same side forms, on described, lower girder and diagonal brace all adopt two channel-section steel make-ups to form, channel-section steel is to the reserved spacing of buckle, and to the upper and lower full weld of buckle, and be welded and fixed by equidistant connection batten plate, on described, intersect and be welded and fixed up and down by described two diagonal braces between lower girder, the place of being welded to connect by the described steel plate of putting more energy into again be welded to connect described on, lower girder and diagonal brace, have anchor hole on described anchor plate.
As optimal way, described upper and lower girder adopts 2 Pin C36a channel-section steel make-ups to form, described diagonal brace adopts 2 Pin C28a channel-section steel make-ups to form, angle at 45 ° between described upper and lower girder and diagonal brace, described channel-section steel is to the reserved 1cm spacing of buckle, and be welded and fixed by the thick connection batten plate of the equally spaced 1cm of spacing 50cm, the described steel plate of putting more energy into is the thick parallelogram of 1cm, described anchor plate is the 2cm steel plate.
The beneficial effects of the utility model: the utility model has solved that triangle bracket compressive strength is low, low bearing capacity, stability is bad, wind resistance low and the problems such as diagonal brace reinforcing can't be carried out in bottom.The utility model, by girder under the carriage bottom increases, is increasing diagonal brace between upper and lower girder, thereby has increased the bearing capacity, intensity, rigidity etc. of carriage.Increase horizontal diagonal brace between the upper and lower girder of every Pin carriage, every Pin carriage is connected into to integral body, thereby increased the stability of carriage, increased the high-altitude wind resistance.The utility model has improved bearing capacity, stability, the wind resistance of carriage greatly.
