Problems solved by technology

[0002] With the current traffic flow of existing highway bridges becoming increasingly saturated, the existing highway bridges cannot meet the needs of future traffic flow, so it is necessary to widen the existing highway bridges
According to the traditional construction technology, it is impossible to realize the construction platform where the newly added column beams are connected with the originally designed pier columns. The piercing rod method construction has no piercing holes reserved for the pier columns in the original design, and the hoop method is difficult to install due to the limited construction height. , great potential safety hazard during installation

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] see figure 1 , the present invention provides a technical solution: a hanger erected on a construction platform constructed after the columns and beams of a highway bridge under construction, which is arranged on both sides of the top cover beam 6 of the existing pier column, including a top bracket 1 and a suspender 3. There are two sets of top brackets 1, two sets of top brackets 1 are respectively arranged on both sides of the boom 3, there are four sets ...

Abstract

The invention relates to the technical field of highway bridge beam column tie beam construction, in particular to a hanging bracket erected on a construction platform constructed after building of ahighway bridge beam column tie beam. The hanging bracket arranged on two sides of a capping beam on the top of an existing pier stud comprises a top brackets and suspenders, and the two sets of top brackets are arranged on the two sides of the suspenders correspondingly. Every two of the four groups of suspenders are arranged at two ends of the top brackets; a top plate is slidably connected to the upper ends of two adjacent groups of suspenders; and the lower ends of every two adjacent groups of suspenders are connected with a bottom plate in a sliding mode. The upper side and the lower sideof the top plate and the upper side and the lower side of the bottom plate are provided with two fastening nuts respectively. The fastening nuts are in threaded connection with the suspenders. A traditional lower compression system is converted into an upper tension system, the hanging bracket has the advantages of being small in dead weight, convenient to assemble and disassemble, low in cost, safe, reliable and convenient to recycle, and a problem that an existing construction platform for newly-added column tie beams under bent caps cannot be erected because center penetrating holes are notreserved and inner hoops with the limited height are difficult to install is effectively solved.
