Triangular supporting frame for construction of oblique leg pier

Abstract

The invention discloses a triangular supporting frame for construction of an oblique leg pier. The triangular supporting frame comprises a triangular supporting frame body, a construction support foundation of a bottom supporting triangular supporting frame body and an external pier formwork for mounting the oblique leg pier. The triangular supporting frame body is of an isosceles triangular structure, and the side edges of the triangular supporting frame body are fixedly connected with the external pier formwork through connection parts. A bearing table is arranged at the bottom of the external pier formwork, a drilling pier and a steel plate pier are arranged on the lower portion of the construction support foundation, and a strip-shaped foundation is pre-buried at the position, close tothe steel plate pier, of the lower surface of the construction support foundation. A top beam is arranged at the joint position of the drilling pier and the construction support foundation. Accordingto the triangular supporting frame, different forms of construction support foundations can be pre-arranged aiming at different geological conditions, the floor space is small, the triangular supporting frame can be machined in a factory in advance, can be assembled and dismounted, and is convenient to construct and transport. Space is saved, construction period is shortened, the triangular supporting frame is suitable for construction of oblique leg piers which are close to river banks and the like, limited by space, and have high requirements for appearance line shapes, and is high in practicality and generalization performance.

Description

technical field [0001] The invention relates to the technical field of inclined-leg pier column construction, in particular to a triangular support frame for inclined-leg pier column construction. Background technique [0002] With the rapid development of our country's economy, the construction industry has become an important part of the development that cannot be ignored. With the increase of people's demand and traffic flow, the construction of roads is becoming more and more diversified, and bridges and even elevated roads are becoming more and more complicated. , all kinds of piers can be seen everywhere in the city, some are upright, and some are in the shape of diagonal braces. Among them, the construction of piers in the shape of diagonal braces is more complicated. [0003] The reason is that the oblique leg pier with a large slope will generate a large horizontal thrust during the concrete pouring process, and the root of the pier is prone to cracking after formin...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a triangular support frame for construction of slanted-leg pier columns, which solves the problem that the above-mentioned traditional scaffolding support method offsets the horizontal thrust, which is faced with complex operation, large space occupation, inconvenient construction and long construction period. Long, unable to meet the construction requirements of inclined-leg pier columns limited by the construction site, and the construction efficiency is low
