Abstract

The invention relates to a high-pier built-in stiff framework cross tie beam structure which comprises a hoop-type corbel bracket. Each hoop is composed of two semi-circular-arc-shaped steel plates, and adopted high-strength bolts are connected with pier columns. An operating platform is formed by assembling, machining and hoisting thick steel plates and profile steel on the ground and connecting the materials with the hoop-type corbel bracket by using high-strength bolts. Penetration-type steel beams are made of profile steel or steel rods, the height and width of penetrating I-steel and the thickness of flange web plates are determined according to self weight, people load and the like, and the penetrating I-steel is manufactured according to design values when being prefabricated. A formwork system consists of a bottom formwork, distributing beams, bearing beams, shoulder pole beams and the like, wherein the parts are connected by adopting bolts. The built-in stiff framework is of a truss structure, is formed by welding channel steel and I-steel and is structurally divided into upper chord rods, diagonal bracings, vertical rods and lower chord rods. The high-pier built-in stiff framework cross tie beam structure has the advantages that a built-in stiff framework construction operation face is small and is relatively closed, no crossed operation exists, and the construction risk is low.

Description

technical field [0001] The invention relates to a structure and a construction method of a rigid skeleton transverse beam structure built into a high pier, in particular to a structure and a construction method of a rigid skeleton transverse beam structure built into a high pier, belonging to the field of bridge engineering. Background technique [0002] At present, with the construction of a large number of highway bridges in our country, the application of long-span bridge engineering in highway bridge construction projects is gradually increasing. As a common construction method, high bridge pier construction plays an important role in stabilizing the bridge during the bridge construction process. With the continuous development of the economy, the construction scale of transportation infrastructure is getting larger and larger, which leads to the increase of the height of bridge piers all over the world, and increases the difficulty of construction to a certain extent. ...
