Problems solved by technology

However, due to the manufacturing error of the column structure and the steel structure, it is impossible for the steel sleeve and the concrete column to be closely bonded. The effect is greatly reduced. The bearing capacity of the steel cap beam mainly depends on the shear screws or anchor bolts, and the bearing capacity is relatively low.

Embodiment Construction

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The invention provides a steel hoop structure for adding a steel cover beam to a pier column. For details, see figure 1 , which includes a concrete column, and its difference from the prior art is that a steel sleeve is arranged around the concrete column, a gap is provided between the steel sleeve and the concrete column, and a cement mortar layer is provided in the gap, so that the steel sleeve forms a steel cage. One or more outwardly extending steel members are arranged outside the steel hoop to for...

Abstract

The invention relates to a steel hoop structure for additionally arranging a steel cover beam on a pier stand column. A steel sleeve is arranged around a concrete stand column, a gap is arranged between the steel sleeve and the concrete stand column, a cement mortar layer is arranged in the gap so that a steel hoop can be formed by the steel sleeve, and the outer side of the steel hoop is providedwith one or more steel components outwards extending so that a steel cover beam structure can be formed. High-strength cement mortar is poured between the steel hoop and the concrete stand column, the bearing force of the steel cover beam or a steel bracket is provided through the powerful frictional resistance of the structure, and the purposes that the structure is simple, connection is reliable, construction is convenient, and the manufacturing cost is economic are achieved.

Description

technical field [0001] The invention relates to the technical field of reinforcement and reconstruction of bridge structures, in particular to a steel hoop structure and installation method for adding a steel cover beam to a bridge pier column, and in particular to an additional steel cover beam structure for a bridge pier concrete column structure. Background technique [0002] At present, when the concrete column of the pier is reinforced or reconstructed, a steel structure cap beam or corbel is added. The existing technology is to make a steel sleeve to surround the column, and then plant a shear-resistant screw or anchor bolt between the steel sleeve and the concrete. The gaps in the concrete are bonded with organic glue, and the steel cover beam is connected with the original concrete column through the shear screw and the adhesive layer to bear the force together. However, due to the manufacturing error of the column structure and the steel structure, it is impossible ...
